  3. Cogeneration for small SAGD projects

    Energy Technology Data Exchange (ETDEWEB)

    Albion, Stuart [AMEC BDR Limited (United Kingdom)

    2011-07-01

    As many SAGD projects are being developed in remote locations, the supply of a steady source of power to them becomes an important question. Connecting these remote facilities to a grid can often be difficult and costly. This presentation, by AMEC BDR Limited, promotes the use of cogeneration in small SAGD projects. Cogeneration is the generation of two forms of energy from one fuel source. In this particular case, the energy forms would be electricity and heat. In many SAGD projects, a gas turbine system is used to generate the electricity, while a heat recovery system is utilized to generate steam. The use of cogeneration systems in SAGD projects, as opposed to using separate heat and electricity systems, has the potential to significantly reduce the amount of energy lost, the amount of emissions and power costs, in addition to ensuring that there is a reliable supply of steam and electricity.

    Balachandran, S.; Jorde, K.

    2008-01-01

    This report for the Swiss Federal Office of Energy (SFOE) discusses the project for a small 16-kilowatt hydro plant on the Gonzenbaechli stream in eastern Switzerland. The site, which was used even before 1860 for obtaining power from the stream is briefly described, as are the present remains of earlier installations. An old Francis turbine has been retrieved and could possibly be reused. Water-flow figures and fall-heights are noted. Design flows and residual water quantities required by legislation are noted and discussed, as are the geology and topology of the catchment area. The proposals for a new hydro-power plant are described, including the apparatus proposed with a power of 20 kVA. Environmental aspects are also discussed, as are the investment costs and the economic viability of the project. The paper is completed with a comprehensive appendix, including detailed cost estimates.

  5. Make Projects Small Form Factor PCs

    Wessels, Duane

    2006-01-01

    Shoebox sized and smaller, small-form-factor PCs can pack as much computing muscle as a full-sized desktop computer. They consumer less power, have few or no moving parts, and are very quiet. Whether you plan to use one as a standalone PC or want to embed it in your next hacking project, a small-form-factor PC can be a lot of fun to build. Make Projects: Small Form Factor PCs is the only book available that shows you how to build small-form-factor PCs -- from kits and from scratch -- that are more interesting and more personalized than what a full-sized PC can give you.

    1993-01-01

    Examples and techniques used to enhance the ability to finance small hydro projects, or to finance them in non-standard ways, were discussed. It was suggested that factors that motivate investors, namely the maximization of the rate of return on capital, and minimization of risk, should be the primary concern for any would-be developer. A responsible, conservative approach to financial projections was recommended as the best to impress potential investors

  7. Cute Boys or Game Boys? The Embodiment of Femininity and Masculinity in Young Norwegians’ Text Message Love-Projects

    Directory of Open Access Journals (Sweden)

    Lin Prøitz

    2005-01-01

    Full Text Available By looking at young Norwegians’ text messages in sexual romantic negotiations, this article examines whether text messages may provide a site for performing femininity and masculinity in ways that subvert traditional conceptions of these constructs. Although various studies on gender, sexuality and media [1] have consistently indicated gender specific usage/performances which in this article is indicated and supported by the study’s young informants’ own formulations, the discourse analysis approach employed a more complex image. Here, I focus on how the young people indicate and translate their modes and body-language into texts, paying particular attention to how signs of femininity and masculinity emerge in text message love-projects, I argue that especially for young males, text messages in love-projects offer a site where in particular young males may perform masculinity in counter-traditional ways. The article is a part of a long study of young Norwegian’s usages, self-understanding and gender performances through text message communication.

  8. Small and low head pumped storage projects

    International Nuclear Information System (INIS)

    Makarechian, A.H.

    1991-01-01

    The purpose of this paper is to focus attention on small and low head pumped storage projects. These projects may be defined as having a capacity of less than 200-300 MW and down to about 20 MW, with heads of 1200 ft to about 300 ft or less. Many advantages of these smaller pumped storage projects include more flexibility in siting of a project, considerably shorter licensing and construction period, adaptability to closed system design concept to reduce adverse environmental impacts, considerably reduced risks of delays and substantial cost over-runs, better suited to meeting peaking capacity requirements for individual utilities, and much less transmission inter-connection requirements. An overall licensing and construction schedule of about 3 to 3 1/2 years is realistic for many smaller pumped storage projects, and competitive costs in terms of dollars per kW installed can be achieved

    Broude, Gwen J.

    1999-01-01

    Many psychologists assert that boys are in dire straits in U.S. society, but in fact, there is no evidence of an emotional or behavioral epidemic for either sex. If there is any truth to the claim that boys are in trouble, it results from practices that foster aggression. It is a mistake to regard either gender as "fragile." (SLD)

    Understanding cosmic acceleration is one of the key science drivers for astrophysics and high-energy physics in the coming decade (2014 P5 Report). With the Large Synoptic Survey Telescope (LSST) and the Dark Energy Spectroscopic Instrument (DESI) and other new facilities beginning operations soon, we are entering an exciting phase during which we expect an order of magnitude improvement in constraints on dark energy and the physics of the accelerating Universe. This is a key moment for a matching Small Projects portfolio that can (1) greatly enhance the science reach of these flagship projects, (2) have immediate scientific impact, and (3) lay the groundwork for the next stages of the Cosmic Frontier Dark Energy program. In this White Paper, we outline a balanced portfolio that can accomplish these goals through a combination of observational, experimental, and theory and simulation efforts.

    2017-01-01

    Heterotopic gastric mucosa has been described at various locations of the body; however, the polyp composed of heterotopic gastric mucosa in the small intestine is rare. A 15-year-old boy visited us for investigation of recurrent episodes of melena. Capsule endoscopy (CE) revealed a polypoid tumor in the ileum, with an active nearby hemorrhage. Contrast-enhanced computed tomography (CECT) showed a tumor in the right quadrant of the abdomen, with a diameter of about 18 × 14 mm. The patient was diagnosed with polypoid gastric heterotopia. We performed an operation to resect the lesion. The patient recovered smoothly after surgery and was discharged on postoperative day 7 and followed up for 3 months. He has not experienced gastrointestinal intestinal (GI) symptoms up to now. Giant polypoid gastric heterotopia in the small intestine is extremely rare, which can express as an occasional finding with or without symptoms. Surgical resection is the preferred therapy when symptoms appear.

  16. Small Hydropower Research and Development Technology Project

    Energy Technology Data Exchange (ETDEWEB)

    Blackmore, Mo [Near Space Systems, Inc.

    2013-12-06

    The objective of this work was to investigate, develop, and validate the next generation of small hydroturbine generator designs that maximize the energy transfer from flowing water to electrical power generation. What resulted from this effort was the design of a new technology hydroturbine that Near Space Systems (NSS) has named the Star*Stream© Hydroturbine. Using a design that eliminates nearly all of the shortfalls of conventional hydroturbines, the Star*Stream© Hydroturbine employs a new mechanical-to-electrical energy transfer hydro design that operates without lubrication of any kind, and does not introduce foreign chemicals or particulate matter from oil or drive shaft seal degradation into the hydro ecology. In its unique configuration, the Star*Stream© Hydroturbine is nearly environmentally inert, without the negative aspects caused by interrupting the ecological continuity, i.e., disruptions to sedimentation, water quality, habitat changes, human displacement, fish migration, etc., - while it ensures dramatically reduced timeframes to project completion. While a remarkable reduction in LCOE resulting from application of the Star*Stream© Hydroturbine technology has been the core achievement of the this effort, there have been numerous technological breakthroughs from the development effort.

  17. Hoopa Valley Small Scale Hydroelectric Feasibility Project

    2009-03-22

    This study considered assessing the feasibility of developing small scale hydro-electric power from seven major tributaries within the Hoopa Valley Indian Reservation of Northern California (http://www.hoopa-nsn.gov/). This study pursued the assessment of seven major tributaries of the Reservation that flow into the Trinity River. The feasibility of hydropower on the Hoopa Valley Indian Reservation has real potential for development and many alternative options for project locations, designs, operations and financing. In order to realize this opportunity further will require at least 2-3 years of intense data collection focusing on stream flow measurements at multiple locations in order to quantify real power potential. This also includes on the ground stream gradient surveys, road access planning and grid connectivity to PG&E for sale of electricity. Imperative to this effort is the need for negotiations between the Hoopa Tribal Council and PG&E to take place in order to finalize the power rate the Tribe will receive through any wholesale agreement that utilizes the alternative energy generated on the Reservation.

  20. A Guide to Bundling Small-scale CDM Projects

    International Nuclear Information System (INIS)

    Mariyappan, J.; Bhardwaj, N.; De Coninck, H.; Van der Linden, N.

    2005-07-01

    Small-scale renewable energy and energy efficiency projects that fit the development needs of many developing countries, can potentially be supported via the Clean Development Mechanism (CDM), one of the Kyoto Protocol's flexible mechanisms for tackling climate change. However, there is concern that due to high transaction costs, as well as many existing barriers, very few investments will be made in small-scale projects, which are often the most suitable development option in countries such as India. In view of this, the 'bundling' together of appropriate small-scale projects on a regional basis has been proposed as a way in which funding can be leveraged from international sources and transaction costs reduced. IT Power, IT Power India and the Energy research Centre of the Netherlands (ECN) are carrying out a 2-year project to establish the capacity within India to enable individual small scale projects to be bundled as a single CDM project. Overall objectives are to develop the necessary institutional capabilities to formulate and implement small scale CDM projects in India; to provide a guide on how to bundle small scale projects under the CDM in developing countries; and to raise the awareness of the potential for investment in small scale energy projects which can gain funding through the CDM

  1. Trevino Project: a fast-track approach for a small construction project

    International Nuclear Information System (INIS)

    Schick, C.J.; Lynn, N.S.

    1982-01-01

    The approach to a construction project can vary according to the size, location, and degree of difficulty associated with the project. This paper deals with one approach that can be taken to a small construction project, the fast-track approach. A small construction project can be defined as a project having less than $20 million capital cost or a project with a low degree of difficulty. This approach is very applicable to in-situ leaching uranium projects, small precious metal operations, etc. The approach to the small project is that of fast-tracking the project in order to minimize the time over which capital expenditure occurs and also to reduce the indirect costs of field expense, construction supplies, construction equipment, etc. In order to fast-track a project it is necessary to do a very precise job on the preliminary phases of the project such as preliminary engineering, plant site location, environmental permits, etc. 2 figures, 2 tables

  2. Managing Small Spacecraft Projects: Less is Not Easier

    Science.gov (United States)

    Barley, Bryan; Newhouse, Marilyn

    2012-01-01

    Managing small, low cost missions (class C or D) is not necessarily easier than managing a full flagship mission. Yet, small missions are typically considered easier to manage and used as a training ground for developing the next generation of project managers. While limited resources can be a problem for small missions, in reality most of the issues inherent in managing small projects are not the direct result of limited resources. Instead, problems encountered by managers of small spacecraft missions often derive from 1) the perception that managing small projects is easier if something is easier it needs less rigor and formality in execution, 2) the perception that limited resources necessitate or validate omitting standard management practices, 3) less stringent or unclear guidelines or policies for small projects, and 4) stakeholder expectations that are not consistent with the size and nature of the project. For example, the size of a project is sometimes used to justify not building a full, detailed integrated master schedule. However, while a small schedule slip may not be a problem for a large mission, it can indicate a serious problem for a small mission with a short development phase, highlighting the importance of the schedule for early identification of potential issues. Likewise, stakeholders may accept a higher risk posture early in the definition of a low-cost mission, but as launch approaches this acceptance may change. This presentation discusses these common misconceptions about managing small, low cost missions, the problems that can result, and possible solutions.

  12. Project Finance Model for Small Contractors in USA

    Directory of Open Access Journals (Sweden)

    Jawahar Nesan

    2012-11-01

    Full Text Available Construction projects do not require a large capital outlay but a large working capital to start up the project. Unfortunately, for small contractors there are very limited options available from the banks or other lending institutions to cover this large working capital requirement in the absence of sufficient collateral. The “Project Finance” method presented in this paper is recommended as the most effective method for small contractors in the United States. The problems of small and start up contractors in funding their projects have been little addressed in the literature. The current financing practices were observed through both the literature review and interviews with contractors and bankers in the western Michigan area and subsequently a system has been proposed which could help a small start-up company seeking higher growth. The growth rates that can be achieved using the project finance system in contrast to the traditional “line of credit” arrangements as illustrated in this paper show that the project finance model is beneficial.

    Small businesses are the cornerstone of the American economy. Over 22 million small businesses account for approximately 99% of employers, employ about half of the private sector workforce, and are responsible for about two-thirds of net new jobs. Many small businesses fared better than the Fortune 500 in 2001. Non-farm proprietors income rose 2.4% in 2001 while corporate profits declined 7.2%. Yet not all is rosy for small businesses, particularly new ones. One-third close within two years of opening. From 1989 to 1992, almost half closed within four years; only 39.5% were still open after six years. Why do some new businesses thrive and some fail? What helps a new business succeed? Industry knowledge, business and financial planning, and good management. Small geothermal businesses are no different. Low- and medium-temperature geothermal resources exist throughout the western United States, the majority not yet tapped. A recent survey of ten western states identified more than 9,000 thermal wells and springs, over 900 low- to moderate-temperature geothermal resource areas, and hundreds of direct-use sites. Many opportunities exist for geothermal entrepreneurs to develop many of these sites into thriving small businesses. The ''Geothermal Small Business Workbook'' (''Workbook'') was written to give geothermal entrepreneurs, small businesses, and developers the tools they need to understand geothermal applications--both direct use and small-scale power generation--and to write a business and financing plan. The Workbook will: Provide background, market, and regulatory data for direct use and small-scale (< 1 megawatt) power generation geothermal projects; Refer you to several sources of useful information including owners of existing geothermal businesses, trade associations, and other organizations; Break down the complicated and sometimes tedious process of writing a business plan into five easy steps; Lead you

  18. IT Project Management in Very Small Software Companies

    DEFF Research Database (Denmark)

    Shakir, Shahid Nadeem; Nørbjerg, Jacob

    2013-01-01

    In developing countries very small software companies (VSSCs) with only 1-10 employees play an important role both in the local economy and as providers of software and services to customers in other parts of the world. Understanding and improving their IT project management (ITPM) practices...... and challenges are, therefore, important in the local as well as the larger context of globalized software development. There is, however, very little research into small shop software practices in developing countries. The current paper explores actual ITPM practices in Pakistani VSSCs based on a qualitative...... study of seven Pakistani VSSCs. We find that some Pakistani ITPM practices are similar to what is reported from VSSCs in other parts of the world, while others seem to be related to the companies' position in the global software development chain. This paper is part of a larger research project aiming...

    2008-07-01

    This report for the Swiss Federal Office of Energy (SFOE) discusses the project for a small 16-kilowatt hydro plant on the Gonzenbaechli stream in eastern Switzerland. The site, which was used even before 1860 for obtaining power from the stream is briefly described, as are the present remains of earlier installations. An old Francis turbine has been retrieved and could possibly be reused. Water-flow figures and fall-heights are noted. Design flows and residual water quantities required by legislation are noted and discussed, as are the geology and topology of the catchment area. The proposals for a new hydro-power plant are described, including the apparatus proposed with a power of 20 kVA. Environmental aspects are also discussed, as are the investment costs and the economic viability of the project. The paper is completed with a comprehensive appendix, including detailed cost estimates.

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) takes a look at fouling problems encountered in small hydro installations. The report is based on ten interviews made with operators of small hydro power stations in Switzerland. A parallel project carried out in Germany is mentioned. A large variation in the degree of fouling in the various hydro power stations is noted. Sources such as leaves in autumn and algae are discussed, as are the various rinsing procedures used to clear the turbines of fouling. Power losses are discussed and measures that can be taken to prevent fouling are described. Measurements made at an installation in Freienstein, Switzerland, are presented and discussed. The report is completed with an appendix containing calculations, details on the Freienstein power plant and the results of interviews made with the ten hydro power installations examined.

  2. Projective embeddings of homogeneous spaces with small boundary

    2009-01-01

    We study open equivariant projective embeddings of homogeneous spaces such that the complement of the open orbit has codimension at least 2. We establish a criterion for the existence of such an embedding, prove that the set of isomorphism classes of such embeddings is finite, and give a construction of the embeddings in terms of Geometric Invariant Theory. A generalization of Cox's construction and the theory of bunched rings enable us to describe in combinatorial terms the basic geometric properties of embeddings with small boundary

    Alvsvaag, S.J.; Maeland, O.A.; Klovning, A.

    1995-01-01

    The new Small Angle TIle Calorimeter (STIC) covers the forward regions in DELPHI. The main motivation for its construction was to achieve a systematic error of 0.1% on the luminosity determination. This detector consists of a ''shashlik'' type calorimeter, equipped with two planes of silicon pad detectors placed respectively after 4 and 7.4 radiation lengths. A veto counter, composed of two scintillator planes, covers the front of the calorimeter to allow e-γ separation and to provide a neutral energy trigger.The physics motivations for this project, results from extensive testbeam measurements and the performance during the 1994 LEP run are reported here.

    2014-09-01

    Corrective Action Unit (CAU) 541 is co-located on the boundary of Area 5 of the Nevada National Security Site and Range 65C of the Nevada Test and Training Range, approximately 65 miles northwest of Las Vegas, Nevada. CAU 541 is a grouping of sites where there has been a suspected release of contamination associated with nuclear testing. This document describes the planned investigation of CAU 541, which comprises the following corrective action sites (CASs): 05-23-04, Atmospheric Tests (6) - BFa Site; 05-45-03, Atmospheric Test Site - Small Boy. These sites are being investigated because existing information on the nature and extent of potential contamination is insufficient to evaluate and recommend corrective action alternatives (CAAs). Additional information will be obtained by conducting a corrective action investigation before evaluating CAAs and selecting the appropriate corrective action for each CAS. The results of the field investigation will support a defensible evaluation of viable CAAs that will be presented in the investigation report. The sites will be investigated based on the data quality objectives (DQOs) developed on April 1, 2014, by representatives of the Nevada Division of Environmental Protection; U.S. Air Force; and the U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Field Office. The DQO process was used to identify and define the type, amount, and quality of data needed to develop and evaluate appropriate corrective actions for CAU 541. The site investigation process also will be conducted in accordance with the Soils Activity Quality Assurance Plan, which establishes requirements, technical planning, and general quality practices to be applied to this activity. The potential contamination sources associated with CASs 05-23-04 and 05-45-03 are from nuclear testing activities conducted at the Atmospheric Tests (6) - BFa Site and Atmospheric Test Site - Small Boy sites.

    2017-05-01

    Although Small Hydropower Projects (SHPs) are encouraged as sources of clean and green energy, there is a paucity of research examining their socio-ecological impacts. We assessed the perceived socio-ecological impacts of 4 SHPs within the Western Ghats in India by conducting semi-structured interviews with local respondents. Primary interview data were sequentially validated with secondary data, and respondent perceptions were subsequently compared against the expected baseline of assured impacts. We evaluated the level of awareness about SHPs, their perceived socio-economic impacts, influence on resource access and impacts on human-elephant interactions. The general level of awareness about SHPs was low, and assurances of local electricity and employment generation remained largely unfulfilled. Additionally most respondents faced numerous unanticipated adverse impacts. We found a strong relationship between SHP construction and increasing levels of human-elephant conflict. Based on the disparity between assured and actual social impacts, we suggest that policies regarding SHPs be suitably revised.

  8. The 150 ns detector project: progress with small detectors

    International Nuclear Information System (INIS)

    Warburton, W.K.; Russell, S.R.; Kleinfelder, Stuart A.; Segal, Julie

    1994-01-01

    This project's long term goal is to develop a pixel area detector capable of 6 MHz frame rates (150 ns/frame). Our milestones toward this goal are: a single pixel, 1x256 1D and 8x8 2D detectors, 256x256 2D detectors and, finally, 1024x1024 2D detectors. The design strategy is to supply a complete electronics chain (resetting preamp, selectable gain amplifier, analog-to-digital converter (ADC), and memory) for each pixel. In the final detectors these will all be custom integrated circuits. The front end preamplifiers are being integrated first, since their design and performance are both the most unusual and also critical to the project's success. Similarly, our early work is also concentrating on devising and perfecting detector structures which are thick enough (1 mm) to absorb over 99% of the incident X-rays in the energy range of interest. In this paper we discuss our progress toward the 1x256 1D and 8x8 2D detectors. We have fabricated sample detectors at Stanford's Center for Integrated Systems and are preparing both to test them individually and to wirebond them to the preamplifier samples to produce our first working small 1D and 2D detectors. We will describe our solutions to the design problems associated with collecting charge in less than 30 ns from 1 mm thick pixels in high resistivity silicon. We have constructed and tested the front end of our preamplifier design using a commercial 1.2 μm CMOS technology and are moving on to produce a few channels of the complete preamplifier, including a switchable gain stage and output stage. We will discuss both the preamplifier design and our initial test results. ((orig.))

  10. Small and medium power reactors: project initiation study, Phase 1

    International Nuclear Information System (INIS)

    1985-07-01

    In conformity with the Agency's promotional role in the peaceful uses of nuclear energy, IAEA has provided, over the past 20 years, assistance to Member States, particularly developing countries, in planning for the introduction of nuclear power plants in the Small and Medium range (SMPR). However these efforts did not produce any significant results in the market introduction of these reactors, due to various factors. In 1983 the Agency launched a new SMPR Project Initiation Study with the objective of surveying the available designs, examining the major factors influencing the decision-making processes in Developing Countries and thereby arriving at an estimate of the potential market. Two questionnaires were used to obtain information from possible suppliers and prospective buyers. The Nuclear Energy Agency of OECD assisted in making a study of the potential market in industrialized countries. The information gained during the study and discussed during a Technical Committee Meeting on SMPRs held in Vienna in March 1985, along with the contribution by OECD-NEA is embodied in the present report

    An audio recording of an address by Chief Stanley Stephens and Deputy-Chief Ken Neegan of the Constance Lake First Nation, at the Renewable Energy Commercial Trade Show and Markets Conference was presented. The speech concerned development of a 15 MW hydro project on the reservation. Stephens recalled how initial opposition was overcome by addressing simple misconceptions about the project. The project was initiated by the Ontario Energy Corporation with a series of community discussions which addressed environmental impacts, and benefits that would result from the project. Neegan explained that after deliberation and negotiations, the Constance Lake First Nation was pleased with the project. This project was evidence that sound partnership could be formed between First Nations and hydro developers, while preserving respect for `Mother Earth` in the process. Trust between the community, the developers and government was considered to be the critical component of the project. Sound legal, technical, environmental and financial information was also indispensable in allowing the Constance Lake First Nation to make its decision to proceed with the project.

    Taylor, Lara A.

    The expansion of small hydro development in British Columbia has raised concerns surrounding the effects of these projects, and the provincial government's decision to proceed with Site C has brought attention to the impacts of large hydro. Together, these decisions highlight that there are impacts associated with all energy development. My study examines the aquatic effects of large and small hydro projects using two case study sites: Site C and the Upper Harrison Water Power Project. I first determine the aquatic effects of each of the case study sites. Next, I use existing literature and benefits transfer to determine the monetary value of these effects. My results suggest that, with mitigation, small hydro projects have less of an effect on the environment than a large hydro project per unit of electricity. I also describe the implications of my study in the context of current British Columbia energy policy. Keywords: hydropower; aquatic effects. Subject Terms: environmental impact assessment; benefits transfer.

    Large amounts of small-scale bioenergy projects were carried out in China's rural areas in light of its national renewable energy policies. These projects applied pyrolysis gasification as the main technology, which turns biomass waste at low costs into biogas. This paper selects seven bioenergy projects in Shandong Province as a case and assesses these projects in terms of economy, technological performance and effectiveness. Results show that these projects have not achieved a satisfying performance after 10 years experience. Many projects have been discontinued. This failure is attributed to a complex of shortcomings in institutional structure, technical level, financial support and social factors. For a more successful future development of bioenergy in rural areas, China should reform its institutional structure, establish a renewable energy market and enhance the technological level of bioenergy projects

    In many afforestation and reforestation (AR) projects harvesting with stand regeneration forms an integral part of the silvicultural system and satisfies local timber and/or fuelwood demand. Especially clear-cut harvesting will lead to an abrupt and significant reduction of carbon stocks. The smaller the project, the more significant the fluctuations of the carbon stocks may be. In the extreme case a small-scale project could consist of a single forest stand. In such case, all accounted carbon may be removed during a harvesting operation and the time-path of carbon stocks will typically look as in the hypothetical example presented in the report. For the aggregate of many such small-scale projects there will be a constant benefit to the atmosphere during the projects, due to averaging effects.

    Girls outscore boys in reading proficiency levels; the gender gap is startling and concerning. The myth that boys won't read or that it's not "cool" for boys to love reading plays a big part in how these low levels come to be. Low expectations from teachers, and an assumption that boys prefer physical activity, mean that boys often don't find…

    Full Text Available The Clean Development Mechanism (CDM of the Kyoto Protocol, allows the non Annex 1 countries to receive projects that contribute to reducing greenhouse gas emissions and sustainable development in developing countries. The CDM, since its inception, has issued credits equivalent to 1.434.737.562 tons of CO2, distributed across 7.450 projects around the world, from 15 different sectors. Sectors 14 that allow forestry projects (such as reforestation and afforestation have registered 53 projects to date; 19 of which are in Latin America. Nevertheless, the contribution of this sector currently represents less than 1% of CDM Certificates of Emissions Reduction (CERs issued. In September 2013, through their National Forestry Financing Fund (FONAFIFO, Costa Rica registered their first CDM project with the United Nations Framework Convention on Climate Change (UNFCCC, after having complied with all the project cycle processes. The project, known as "Carbon Sequestration in Small and Medium Farms, Brunca Region, Costa Rica" was a project executed by FONAFIFO under their Environmental Services Payment Program.

    Full Text Available This article aims to analyze the structuring stage and use of information systems in project management in small and medium-sized companies in the business of providing services in industrial automation. Information systems applied to project management - SIGPs can contribute to decision-making on projects, assisting in the management of reliable information in real time, making it a natural choice for most companies looking to increase performance management of their projects. The research method used was multiple case study, in line with the explanatory nature of the study, when to investigate and perform analytical comparisons on how small and medium-sized enterprises of the studied branch structure and use the SIGPs, considering the contemporary character theme and the possibility of direct observation of the object of study, in addition to conducting interviews. The main results were identified the main gaps in project management in companies and research as the management characteristics of these SMEs have influence in how their projects are managed. It was observed that there is a predominance of features involving scope, time and resources on projects, whereas aspects related to costs, risks, quality, procurement and communications have unimpressive results in relation to structuring.

  13. EXPLORING THE POLITICS OF LOCAL PARTICIPATION IN RURAL DEVELOPMENT PROJECTS: SMALL DAMS REHABILITATION PROJECT IN ZIMBABWE

    Directory of Open Access Journals (Sweden)

    Jacob Tagarirofa

    2013-02-01

    Full Text Available The study sought to evaluate the effectiveness of community participation in rural development projects in Zimbabwe testing the credibility of the popularized supposition that almost all contemporary development efforts characteristically embrace local participation. Public participation is widely assumed to be an essential ingredient for the fruition of rural development efforts. The research made use of quantitative and qualitative research methodologies in which unstructured interviews, focus group discussions and questionnaires were used as data gathering instruments. The analysis of data was enabled by the use of People-Centered Development (PCD as a conceptual framework. Findings revealed that the level of community participation in the district is not only minimal, but it is also top down. This has much to do with the negative perceptions by facilitating agents viewing local people as passive recipients of externally crafted models of development and other factors such as the power dynamics within and between the community and other stakeholders. The research also found preferential treatment of other tribal groups by the facilitating agent, intra group conflicts and bureaucratic and political influence as obstacles militating against effective participation. Based on these findings, and consistent with the wider literature, recommendation are that the nature of community engagement should be based on the principle of equal partnership among all stakeholders as this would encourage full cooperation and thus effective participation.

    Full Text Available The ATLAS collaboration has chosen the Micromegas technology along with the small-strip Thin Gap Chambers for the upgrade of the inner muon station in the high-rapidity region, the so called New Small Wheel upgrade project. It will employ eight layers of Micromegas and eight layers of small-strip Thin Gap Chambers per wheel. The New Small Wheel project requires fully efficient Micromegas chambers, able to cope with the maximum expected rate of 15 kHz/cm2 featuring single plane spatial resolution better than 100 μm. The Micromegas detectors will cover a total active area of ~ 1200 m2 and will be operated in a moderate magnetic field (≤ 0.3 T. Moreover, together with their precise tracking capability the New Small Wheel Micromegas chambers will contribute to the ATLAS Level-1 trigger system. Several studies have been performed on small (10 × 10 cm2 and medium (1 × 0.5 m2 size prototypes using medium (1 − 5 GeV/c and high momentum (120 – 150 GeV/c hadron beams at CERN. A brief overview of the results obtained is presented.

    2009-01-01

    Los Alamos National Laboratory, Carlsbad Office (LANL-CO), has been tasked to write Project Plans for all of the Small Quantity Sites (SQS) with defense related Transuranic (TRU) waste in the Department of Energy (DOE) complex. Transuranic Work-Off Plans were precursors to the Project Plans. LANL-CO prepared a Work-Off Plan for each small quantity site. The Work-Off Plan that identified issues, drivers, schedules, and inventory. Eight sites have been chosen to deinventory their legacy TRU waste; Bettis Atomic Power Laboratory, General Electric-Vallecitos Nuclear Center, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory-Area 300, Nevada Test Site, Nuclear Radiation Development, Sandia National Laboratory, and the Separations Process Research Unit. Each plan was written for contact and/or remote handled waste if present at the site. These project plans will assist the small quantity sites to ship legacy TRU waste offsite and de-inventory the site of legacy TRU waste. The DOE is working very diligently to reduce the nuclear foot print in the United States. Each of the eight SQSs will be de-inventoried of legacy TRU waste during a campaign that ends September 2011. The small quantity sites have a fraction of the waste that large quantity sites possess. During this campaign, the small quantity sites will package all of the legacy TRU waste and ship to Idaho or directly to the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico. The sites will then be removed from the Transuranic Waste Inventory if they are de-inventoried of all waste. Each Project Plan includes the respective site inventory report, schedules, resources, drivers and any issues. These project plans have been written by the difficult waste team and will be approved by each site. Team members have been assigned to each site to write site specific project plans. Once the project plans have been written, the difficult team members will visit the sites to ensure nothing has

    2014-01-01

    In the last few years, the distributed energy production from small wind turbines (i.e.<200 kWp) has developed into a relevant business opportunity for different investors in Italy. The market, especially in Italy, has rapidly grown, achieving 9 MWp only in 2011, with an increase from 1.5 MW in 2009 to 13.3 MW at the end of 2011. This paper reports the results of a case study on the installation of several small wind turbines. It aims to provide an analysis of the conditions in Italy that make it possible to install these machines and offer a reliable reference for designing, planning, and controlling small wind turbine projects while focusing on the strategic variables of time, cost, and quality used by typical enterprises in the investment projects. The results are relevant to investors as well as engineering, procurement, and construction companies involved in this new sector, which must understand Italy’s renewable energy policy and its effects in practice. Moreover, certain national energy policy conclusions are reported and discussed in this paper. To properly study the sector, the data on time, cost and quality are analysed using typical project management tools. - Highlights: • Focus on the Italian wind energy sector. • Analysis of Italian policy effects. • Focus on small/medium size wind energy machines

  20. Clean development mechanism and off-grid small-scale hydropower projects: Evaluation of additionality

    International Nuclear Information System (INIS)

    Tanwar, Nitin

    2007-01-01

    The global climate change mitigation policies and their stress on sustainable development have made electrification of rural mountainous villages, using small hydro, an attractive destination for potential clean development mechanism (CDM) projects. This invariably involves judging the additionality of such projects. The paper suggests a new approach to judge the additionality of such stand-alone small hydropower projects. This has been done by breaking up additionality into two components: external and local. The external additionality is project developer dependent. For determining the local additionality, the paper takes into account the probability of a village getting electrified over a period of time, which is kept equal to the possible crediting period. This is done by defining an electrification factor (EF) whose value depends on the degree of isolation, financial constraints and institutional constraints encountered while electrifying a mountainous village. Using this EF, the additionality of a CDM project can be judged in a much easier and accurate way. The paper is based on the data and inputs gathered during site visits to many isolated villages located in the eastern Indian Himalayas

    2000-01-01

    This paper presents a new method for two-dimensional image reconstruction by using a multi-layer neural network. Though a conventionally used object function of such a neural network is composed of a sum of squared errors of the output data, we define an object function composed of a sum of squared residuals of an integral equation. By employing an appropriate numerical line integral for this integral equation, we can construct a neural network which can be used for CT image reconstruction for cases with small amount of projection data. We applied this method to some model problems and obtained satisfactory results. This method is especially useful for analyses of laboratory experiments or field observations where only a small amount of projection data is available in comparison with the well-developed medical applications.

    2016-12-01

    Concerns about equitable workloads for nursing faculty have been well documented, yet a standardized system for workload management does not exist. A project team was challenged to establish an academic workload management system when two dissimilar universities were consolidated. Tuckman's model of small-group development was used as the framework for the analysis of processes and effectiveness of a workload project team. Agendas, notes, and meeting minutes were used as the primary sources of information. Analysis revealed the challenges the team encountered. Utilization of a team charter was an effective tool in guiding the team to become a highly productive group. Lessons learned from the analysis are discussed. Guiding a diverse group into a highly productive team is complex. The use of Tuckman's model of small-group development provided a systematic mechanism to review and understand group processes and tasks. [J Nurs Educ. 2016;55(12):675-681.].

    Although the Three Gorges Project (TGP) may have affected the population structure and distribution of plant and animal communities, few studies have analyzed the effect of this project on small mammal communities. Therefore, the present paper compares the small mammal communities inhabiting the beaches of Dongting Lake using field investigations spanning a 20-year period, both before and after the TGP was implemented. Snap traps were used throughout the census. The results indicate that the TGP caused major changes to the structure of the small mammal community at a lake downstream of the dam. First, species abundance on the beaches increased after the project commenced. The striped field mouse (Apodemus agrarius) and the Norway rat (Rattus norvegicus), which rarely inhabited the beach before the TGP, became abundant (with marked population growth) once water was impounded by the Three Gorges Reservoir. Second, dominant species concentration indices exhibited a stepwise decline, indicating that the community structure changed from a single dominant species to a more diverse species mix after TGP implementation. Third, the regulation of water discharge release by the TGP might have caused an increase in the species diversity of the animal community on the beaches. A significant difference in diversity indices was obtained before and after the TGP operation. Similarity indices also indicate a gradual increase in species numbers. Hence, a long-term project should be established to monitor the population fluctuations of the Yangtze vole (Microtus fortis), the striped field mouse and the Norway rat to safeguard against population outbreaks (similar to the Yangtze vole outbreak in 2007), which could cause crop damage to adjacent farmland, in addition to documenting the succession process of the small mammal community inhabiting the beaches of Dongting Lake. © 2013 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and Wiley

    2017-10-01

    Full Text Available The paper proposes a systematization of the key success factors of projects, through the theoretical review of family-owned companies operating in the EU market. It is the small and medium companies that in their own way contribute to the overall success of the national economy in terms of economic activity, increased employment, development activities and defining better business environment. The theoretical review observed numerous studies of family businesses, and the contribution of this work is in the systematization of the results of previous research – over three horizons, i.e., over the role of managers in the creation of successful projects (or owner if it is a family enterprise, institutional support for companies in Serbia and the EU, specific industries and the parent (regional markets where a family company operates. Project management, as a general representation of the concept of implementation of strategic and operational endeavors, contains many specifics in terms of critical success factors of projects depending on the environment in which they are implemented. The goal of the paper is reflected in the identification and presentation of critical success factors of projects implemented in family companies. The paper concludes with a discussion of the research results in relation to the existing, similar research studies, as well as with the announcement of future research, which will examine the conclusions drawn on a real sample.

  18. Cooperation and communication challenges in small-scale eHealth development projects.

    Petersen, Lone Stub; Bertelsen, Pernille; Bjørnes, Charlotte

    2013-12-01

    In eHealth development there is an increasing focus on user participation inspired by the information systems field of practice and research. There are, however, many other challenges in developing information systems that fit healthcare practices. One of these is the challenge of cooperation and communication in development projects that are initiated and managed by clinicians e.g. cooperating with IT professionals in 'bottom up' health informatics projects that have been initiated and are managed by healthcare professional project managers. The analysis and results are drawn from a qualitative case study on a systems development project that was managed by a local, non-technical, healthcare professional and the complex blend and interactions with the IT professionals in the phases of ideas, design, development, implementation, maintenance and distribution. We analyze the challenges of cooperation and communication using perspectives from information systems research and the concepts of 'language-games' and 'shared design spaces', and thereby exploring the boundaries between the different communication, practice and culture of the IT professionals and the healthcare professionals. There is a need to (a) develop a better understanding of the development process from the point of view of the 'user' and (b) tools for making technical knowledge explicit in the development process. Cooperative and communicative methods are needed that support and develop the shared design spaces between IT professionals and the clinical context in order to strengthen small-scale health information systems projects.

    Pinho, Paulo; Maia, Rodrigo; Monterroso, Ana

    2007-01-01

    In most Environmental Impact Assessment (EIA) systems environmental authorities can stop an EIA process by refusing the respective EIA Report, on the grounds of technical or methodological insufficiencies identified in the review procedure. However, often times, it cannot be taken for granted that, once an EIA Report is formally accepted, as part of an EIA process, its quality standard is, consistently, of a satisfactory level. This paper summarises the results of a one-year research project aimed at assessing the quality of EIA studies carried out for small hydropower plants in Portugal. An extensive survey was carried out to analyse all EIA Reports that were the basis of successful EIA processes involving this kind of small scale projects, under the old and the new national EIA legislation, that is, over the last two decades. Often times unnoticeable to the general public and the media, located in isolated areas upstream secondary rivers, these projects are likely to generate some significant environmental impacts, in particular on the aesthetics value and character of local landscapes and on pristine ecological habitats. And yet, they are usually regarded as environmental friendly projects designed to produce emission free energy. The design of the evaluation criteria benefited from the literature review on similar research projects carried out in other EU countries. The evaluation exercise revealed a number of technical and methodological weaknesses in a significant percentage of cases. A set of simple and clear cut recommendations is proposed twofold: to improve the current standard of EIA practice and to strengthen the role of the so called EIA Commissions, at the crucial review stage of the EIA process

  2. Scientific projects as a way to provide dynamism in small French remote colleges.

    Science.gov (United States)

    Boer, Michel; Strajnic, Jean

    Scientific projects as a way to provide dynamism in small French remote colleges. Though 77% of the French population lives in towns, they are still quite a lot of people in rural areas. The educational model has favored the proximity colleges instead of forcing the students to make long journeys to get to the school, or to be in boarding schools. This means that grade 6-9 students can be in colleges as small as 100-150 children, specifically in remote areas, e.g. in the Alpes de Haute-Provence. Though small structures have many advantages in terms of discipline and proximity of the educational team with both the students and their parents, some "conservatism" may arise from the low turnover of the population. Children stay for long in the same village, and their access to culture, activities, knowledge of the outside can be restricted, inducing a loss of dynamism. In order to fight this tendency the Observatoire de Haute-Provence has started a program together with the regional educational authorities and the teacher teams proposing to work on scientific projects in astronomy, and soon in environmental sciences. Though the children and their teachers visit OHP, and scientists the college, the idea is that the teachers and the classmates become autonomous, the link being maintained via videoconferencing and electronic blackboard. This is based also on the presence of a prominent scientific institute in a rural district.

    Full Text Available The aim of this paper is to determine small and medium enterprise (SME social media activities and promote CE scholarship engagement. It is a community engagement project conducted in the Tshwane community. Community engagement (CE as a planned process with the specific purpose of working with identified groups of people in the community to address issues affecting their well-being. The CE project SME skills transfer workshops are aimed at expanding involvement with the community. The benefits of social media seem to be ignored by most SMEs however; challenges prevent SME owners from using the tool effectively. A survey study method of research design has been selected for the research. The sample for the study comprised 200 SME owners who currently manage small businesses in the Tshwane area. The conducted research recommends that social media can be cost effective if the SMEs make use of their social networks and use best practises that enable them to get their adverts or posts shared across social networks. The conducted research also recommends that SMEs with limited resources start with social media and YouTube as a marketing tool, as the learning curve is low and cost involved is almost nil.

    2015-01-01

    Micromegas, an abbreviation for Micro MEsh Gaseous Structure (MM), is a robust detector with excellent spatial resolution and high rate capability. An $R\\&D$ activity, called Muon ATLAS MicroMegas Activity (MAMMA), was initiated in 2007 in order to explore the potential of the MM technology for use in the ATLAS experiment. After several years of prototyping and testing, the ATLAS collaboration has chosen the MM technology along with the small-strip Thin Gap Chambers (sTGC) for the upgrade of the inner muon station in the high-rapidity region, the so called New Small Wheel (NSW) upgrade project. It will employ eight layers of MM and eight layers of sTGC detectors per wheel. The NSW project requires fully efficient MM chambers, able to cope with the maximum expected rate of $15\\,\\mathrm{kHz/cm^2}$ featuring single plane spatial resolution better than $100\\,\\mu\\mathrm{m}$. The MM detectors will cover a total active area of $\\sim1200\\,\\mathrm{m^2}$ and will be operated in a moderate magnetic field with intens...

    2009-08-24

    The Sludge Treatment Project (STP) is considering two different concepts for the retrieval, loading, transport and interim storage of the K Basin sludge. The two design concepts under consideration are: (1) Hydraulic Loading Concept - In the hydraulic loading concept, the sludge is retrieved from the Engineered Containers directly into the Sludge Transport and Storage Container (STSC) while located in the STS cask in the modified KW Basin Annex. The sludge is loaded via a series of transfer, settle, decant, and filtration return steps until the STSC sludge transportation limits are met. The STSC is then transported to T Plant and placed in storage arrays in the T Plant canyon cells for interim storage. (2) Small Canister Concept - In the small canister concept, the sludge is transferred from the Engineered Containers (ECs) into a settling vessel. After settling and decanting, the sludge is loaded underwater into small canisters. The small canisters are then transferred to the existing Fuel Transport System (FTS) where they are loaded underwater into the FTS Shielded Transfer Cask (STC). The STC is raised from the basin and placed into the Cask Transfer Overpack (CTO), loaded onto the trailer in the KW Basin Annex for transport to T Plant. At T Plant, the CTO is removed from the transport trailer and placed on the canyon deck. The CTO and STC are opened and the small canisters are removed using the canyon crane and placed into an STSC. The STSC is closed, and placed in storage arrays in the T Plant canyon cells for interim storage. The purpose of the cost estimate is to provide a comparison of the two concepts described.

    NEOShield-2 project was selected in the framework of the European Commission H2020 program in answer to the call for “Access technologies and characterisation for Near Earth Objects (NEOs)”. NEOShield-2 project (2015-2017) is a follow-up of the first NEOShield (2012-2015) and includes 11 European Institutions and Industries. The main objectives of NEOShield-2 project are: i) technological development on techniques and instruments needed for GNC for possible asteroid missions and ii) characterization of NEOs of small sizes.Our team at LESIA is the leader of the entire observational program which involved complementary techniques to provide physical and compositional characterization of NEOs. Priority has been given to potential space-mission targets, optimized for mitigation or exploration missions. In this framework an agreement with the European Southern Observatory was signed to obtain Guaranteed Time Observations at the 3.6-meter NTT with an allocation of 30 nights to characterize by spectroscopy the composition of the smaller asteroids. The objects with an absolute magnitude larger than 20 were selected, with a priority for the very small newly discovered objects.We obtained more than 170 new spectra of NEOs. The observations were performed with EFOSC2 instrument. We covered the wavelength interval 0.4-0.92 microns, with a resolution of R=~200. The observed asteroids include 29 asteroids with diameters smaller than 100 meters and 71 with diameters between 100 and 300 m.The taxonomic type has been assigned for 137 individual objects. Our results on NEO mineralogical compositions provide a body of reference data directly applicable to the design and development of mitigation-relevant space missions. Within our survey, we found eight D-types with ΔV funding by European Commission Horizon 2020 program (contract No. PROTEC-2-2014-640351).

    Full Text Available This work presents the assessment of the development and evolution of an active methodology (Project-Based Learning –PBL- implemented on the course “Unit Operations in Environmental Engineering”, within the bachelor’s degree in Environmental Engineering, with the purpose of decreasing the dropout rate in this course. After the initial design and implementation of this methodology during the first academic year (12/13, different modifications were adopted in the following ones (13-14, 14-15 & 15-16 in order to optimize the student’s and professor’s work load as well as correct some malfunctions observed in the initial design of the PBL. This active methodology seeks to make students the main architects of their own learning processes. Accordingly, they have to identify their learning needs, which is a highly motivating approach both for their curricular development and for attaining the required learning outcomes in this field of knowledge. The results obtained show that working in small teams (cooperative work enhances each group member’s self–learning capabilities. Moreover, academic marks improve when compared to traditional learning methodologies. Nevertheless, the implementation of more active methodologies, such as project-based learning, in small groups has certain specific characteristics. In this case it has been implemented simultaneously in two different groups of 10 students each one. Such small groups are more heterogeneoussince the presence of two highly motivated students or not can vary or affect the whole group’s attitude and academic results.

    Small and medium commercial customers in California make up about 20-25% of electric peak load in California. With the roll out of smart meters to this customer group, which enable granular measurement of electricity consumption, the investor-owned utilities will offer dynamic prices as default tariffs by the end of 2011. Pacific Gas and Electric Company, which successfully deployed Automated Demand Response (AutoDR) Programs to its large commercial and industrial customers, started investigating the same infrastructures application to the small and medium commercial customers. This project aims to identify available technologies suitable for automating demand response for small-medium commercial buildings; to validate the extent to which that technology does what it claims to be able to do; and determine the extent to which customers find the technology useful for DR purpose. Ten sites, enabled by eight vendors, participated in at least four test AutoDR events per site in the summer of 2010. The results showed that while existing technology can reliably receive OpenADR signals and translate them into pre-programmed response strategies, it is likely that better levels of load sheds could be obtained than what is reported here if better understanding of the building systems were developed and the DR response strategies had been carefully designed and optimized for each site.

  11. Using Service-Learning Projects to Jump Start Research at Small Institutions

    Geoscientists at small institutions must frequently be very creative about funding and conducting research. High teaching loads, tuition-driven budgets, and a dearth of geosciences colleagues all contribute challenges to an intellectual life that includes research as a scholarship endeavor. Fortunately, service-learning can be used as a multi-purpose pedagogical technique. Unity College is a very small environmentally-focused undergraduate institution in rural Maine with a student population of less than 600 students. Our students really appreciate learning in the field and through participation in projects that impact the communities in which they live and study. Our Environmental Science (geosciences) and Environmental Analysis (chemistry) majors have been showing increasing interest in pursuing graduate school and independent projects in greater and greater depth. In the past 5 years we have had a complete turn-over in geoscience and chemistry faculty (2 persons), a shift that has brought new ideas to campus and a different idea about importance of research. Unity College has always been a big proponent of community-based projects so the extension to service learning as a pedagogical technique has been smooth. A wide variety of towns, schools, land trusts, pond associations and other groups approach Unity College with project ideas. We are best equipped to handle suggestions that relate to environmental chemistry and to lake sedimentation owing to the research interests of our geoscience faculty. We present two examples of ways to sequence student work that ultimately end in student/faculty research projects. Sophomores in the Unity College Environmental Stewardship Core curriculum may choose to take a course that introduces lake sedimentation as a tool to study environmental change. Students in the course take several sediment cores to analyze proxies of environmental change to reconstruct past environments. The final results are reported to the community

    Much information has been collected during the Seminar on Jatropha held in Wageningen, Netherlands, March 2007, summarized in this paper. Much research is still necessary to improve yield, to allow use of biological products such as oil cake as animal fodder, etc. Good documented yield data are still scarce. Cooperation with research institutions is therefore recommended. At this stage it is still particularly important to distinguish between reality, promises and dangerous extrapolations. To avoid, spectacular and regretful failures and waste of money for investors as well as great disappointments of local populations, promoters of large scale plantation are invited to adopt stepwise approaches: large scale plantations should only be considered after some 4 to 5 years obtaining experimental data (annual seed yield and oil yield, economical viability etc.) from a sufficient number of small scale experimental plots (about 1 ha) corresponding to the whole range of soil and climatic conditions of such projects.

The installation is in the Hofenmuehle, a listed mill complex dating from the first half of the nineteenth century. The headrace channel has already been refurbished by a community service group. The high level of financial effort and the idealism of the owner families are noted. The existing installations are described in detail. The refurbishment of the technical equipment and the associated work such as water-flow measurements are discussed. Cost estimates and environmental aspects are presented and discussed as are the financing of the refurbishment work and the cost-covering remuneration for the power produced. A possible increase in the power produced and the associated water-usage concession are discussed.

  15. Small angle neutron scattering. Report of a coordinated research project 2000-2003

    International Nuclear Information System (INIS)

    2006-03-01

    Small angle neutron scattering (SANS) is a powerful technique for studying macro structures like polymers, precipitates in metallurgical specimens, biological molecules, micelles and magnetic systems like ferrofluids. Neutron scattering has an advantage over X ray scattering (XSAXS) due to selective absorption and scattering cross section of neutrons across the periodic table. It is possible to develop and use a SANS instrument even with a medium flux reactor. The present CRP was aimed at the development of components like collimators, monochromators, position sensitive detectors (PSD) etc. for improving the throughput of the instrument and foster the effective utilization of research reactors, as well as to provide a link between developing and developed facilities. The CRP was launched with the first research coordination meeting (RCM) in 2000 to refine the project proposals and define the action plans and partnerships. There were eight research contracts and four research agreements. Good partnerships were established between various participants with collaborations among participants from various countries including those from developing and developed countries. The progress of the individual projects and team work under the CRP was evaluated and discussed during the second RCM and the action plan for the final phase was formulated. The results of the work done under the CRP were then reviewed in the final RCM held in Vienna, December 2003. This publication presents the results of the work carried out by the participants under the CRP at their respective institutions. The information will be useful for the users and operators of research reactors in developing an instrument and building collaborations for capacity building.

    The satellite market is shifting towards smaller (micro and nanosatellites), lowered mass and increased performance platforms. Nanosatellites and picosatellites have been used for a number of new, innovative and unique payloads and missions. This trend requires new concepts for a reduced size, a better performance/weight ratio and a reduction of onboard power consumption. In this context, disruptive technologies, such as laser-optical communication systems, are opening new possibilities. This paper presents the C3PO1 system, "advanced Concept for laser uplink/ downlink CommuniCation with sPace Objects", and the first results of the development of its key technologies. This project targets the design of a communications system that uses a ground-based laser to illuminate a satellite, and a Modulating Retro-Reflector (MRR) to return a beam of light modulated by data to the ground. This enables a downlink, without a laser source on the satellite. This architecture suits well to small satellite applications so as high data rates are potentially provided with very low board mass. C3PO project aims to achieve data rates of 1Gbit/s between LEO satellites and Earth with a communication payload mass of less than 1kilogram. In this paper, results of the initial experiments and demonstration of the key technologies will be shown.

    2010-11-01

    Full Text Available During the design phase, decisions are made that affect, on average, 70% of the life-cycle cost of a building. Therefore, collaborative design relying on multidisciplinary knowledge of the building life cycle is essential. Building information modelling (BIM makes it possible to integrate knowledge from various project participants that traditionally work in different phases of the building process. BIM has been applied in a number of large-scale projects in the industrial real estate and infrastructure sectors in different countries, including The Netherlands. The projects in the housing sector, however, are predominantly small scale and carried out by small and medium enterprises (SMEs. These SMEs are looking for practical and affordable BIM solutions for housing projects. This article reports a pilot project of small-scale housing development using BIM in the province of Zeeland, The Netherlands. The conceptual knowledge derived from European and national research projects is disseminated to the SMEs through a series of experimental working sessions. Action learning protocols within a pilot project are developed to ensure direct impacts in terms of cost reduction and quality improvement. The project shows that BIM can be applied without radical changes to the SMEs' information and communication technology systems or to their business organizations.

    Du Randt, Francois Jean

    2014-08-01

    Full Text Available Projects that fail, for whatever reason, can impact negatively on society, organisations, and other stakeholders. A number of researchers have identified various critical success factors (CSFs that can influence the outcome and success of a project. This research therefore aims to determine the CSFs that influence various success measures of small- to medium-sized projects at a South African mining company, Exxaro Resources’ Grootegeluk Coal Mine. Other objectives of this research include determining the extent of the impacts of these CSFs on the different success measures of a project. The investigation suggests that there are correlations among CSFs, and that certain factors impact the outcome of projects far more than others. This research finds that the single most important CSF for small- to medium-sized projects is the selection of a competent project manager. The competent project manager is characterised by a group of interrelated CSF factors: good leadership, commitment, and learning from past experiences. Based on the research results, other CSFs are discussed and explored in order for recommendations to be made on how this mining company, and possibly other organisations, can achieve greater project success.

  20. Managing Astronomy Research Data: Case Studies of Big and Small Research Projects

    Astronomy data management refers to all actions taken upon data over the course of the entire research process. It includes activities involving the collection, organization, analysis, release, storage, archiving, preservation, and curation of research data. Astronomers have cultivated data management tools, infrastructures, and local practices to ensure the use and future reuse of their data. However, new sky surveys will soon amass petabytes of data requiring new data management strategies.The goal of this dissertation, to be completed in 2015, is to identify and understand data management practices and the infrastructure and expertise required to support best practices. This will benefit the astronomy community in efforts toward an integrated scholarly communication framework.This dissertation employs qualitative, social science research methods (including interviews, observations, and document analysis) to conduct case studies of data management practices, covering the entire data lifecycle, amongst three populations: Sloan Digital Sky Survey (SDSS) collaboration team members; Individual and small-group users of SDSS data; and Large Synoptic Survey Telescope (LSST) collaboration team members. I have been observing the collection, release, and archiving of data by the SDSS collaboration, the data practices of individuals and small groups using SDSS data in journal articles, and the LSST collaboration's planning and building of infrastructure to produce data.Preliminary results demonstrate that current data management practices in astronomy are complex, situational, and heterogeneous. Astronomers often have different management repertoires for working on sky surveys and for their own data collections, varying their data practices as they move between projects. The multitude of practices complicates coordinated efforts to maintain data.While astronomy expertise proves critical to managing astronomy data in the short, medium, and long term, the larger astronomy

  6. Extraction of the respiratory signal from small-animal CT projections for a retrospective gating method

    2008-01-01

    We propose a retrospective respiratory gating algorithm to generate dynamic CT studies. To this end, we compared three different methods of extracting the respiratory signal from the projections of small-animal cone-beam computed tomography (CBCT) scanners. Given a set of frames acquired from a certain axial angle, subtraction of their average image from each individual frame produces a set of difference images. Pixels in these images have positive or negative values (according to the respiratory phase) in those areas where there is lung movement. The respiratory signals were extracted by analysing the shape of the histogram of these difference images: we calculated the first four central and non-central moments. However, only odd-order moments produced the desired breathing signal, as the even-order moments lacked information about the phase. Each of these curves was compared to a reference signal recorded by means of a pneumatic pillow. Given the similar correlation coefficients yielded by all of them, we selected the mean to implement our retrospective protocol. Respiratory phase bins were separated, reconstructed independently and included in a dynamic sequence, suitable for cine playback. We validated our method in five adult rat studies by comparing profiles drawn across the diaphragm dome, with and without retrospective respiratory gating. Results showed a sharper transition in the gated reconstruction, with an average slope improvement of 60.7%

    This document is to fulfill the final report requirements for the Small Business Voucher (SBV) CRADA project with ORNL and KCF Technologies (CRADA/NFE-16-06133). Pumping systems account for nearly 20% of the world’s electrical energy demand and range from 25-50% of the energy usage in many industrial and building power plants. The energy cost is the largest element in the total cost of owning a pump (~40%). In response to a recent DOE mandate for improved pump efficiency pump manufacturers are preparing for the changes that the impending regulations will bring, including design improvements. This mandate also establishes a need for new low cost pump efficiency measurement systems. The standard industry definition of pump efficiency is the mechanical water horsepower delivered divided by the electrical horsepower input to the motor. KCF Technologies has developed a new sensor measurement technique to estimate fluid pump efficiency using a thermodynamic approach. KCF Technologies applied for a SBV grant with ORNL as the research partner. KCF needed a research partner with the proper facilities to demonstrate the efficacy of its wireless sensor unit for measuring pump efficiency. The ORNL Building Technologies Research and Integration Center (BTRIC) test resources were used to test and demonstrate the successful measurement of pump efficiency with the KCF sensor technology. KCF is now working on next steps to commercialize this sensing technology.

    We propose a retrospective respiratory gating algorithm to generate dynamic CT studies. To this end, we compared three different methods of extracting the respiratory signal from the projections of small-animal cone-beam computed tomography (CBCT) scanners. Given a set of frames acquired from a certain axial angle, subtraction of their average image from each individual frame produces a set of difference images. Pixels in these images have positive or negative values (according to the respiratory phase) in those areas where there is lung movement. The respiratory signals were extracted by analysing the shape of the histogram of these difference images: we calculated the first four central and non-central moments. However, only odd-order moments produced the desired breathing signal, as the even-order moments lacked information about the phase. Each of these curves was compared to a reference signal recorded by means of a pneumatic pillow. Given the similar correlation coefficients yielded by all of them, we selected the mean to implement our retrospective protocol. Respiratory phase bins were separated, reconstructed independently and included in a dynamic sequence, suitable for cine playback. We validated our method in five adult rat studies by comparing profiles drawn across the diaphragm dome, with and without retrospective respiratory gating. Results showed a sharper transition in the gated reconstruction, with an average slope improvement of 60.7%.

    We report on three boys suffering from achondroplasia concurrent with enchondromatosis-like metaphyseal changes. Two boys who were examined by molecular analysis harbored a mutation of FGFR3, which occurs in most achondroplastic individuals. Given the prevalence of achondroplasia and enchondromatosis, the metaphyseal changes in these patients are less likely to represent the coincidence of both disorders, but rather to result from a rare consequence of the FGFR3 mutation. Impaired FGFs/FGFR3 signaling pathway in achondroplasia inhibits chondrocytic proliferation, which accounts for most characteristics of achondroplasia. On the other hand, it causes conflicting biological consequences that can suppress or stimulate chondrocytic maturation. In a small subset of achondroplastic individuals, the suppression of chondrocytic maturation may outweigh the stimulation, which leads to cartilaginous overgrowth into the metaphysis, eventually causing the metaphyseal dysplasia found in the present patients.

    2007-01-01

    Setting baseline emissions is one of the principal tasks involved in awarding credits for greenhouse gas emission (GHG) mitigation projects under the Clean Development Mechanism (CDM). An emission baseline has to be project-specific in order to be accurate. However, project-specific baseline calculations are subject to high transaction costs, which disadvantage small-scale projects. For this reason, the CDM-Executive Board (CDM-EB) has approved simplified baseline methodologies for selected small-scale CDM project categories. While the simplified methods help reduce the transaction cost, they may also result in inaccuracies in the estimation of emission reductions from CDM projects. The purpose of this paper is to present a rigorous economic scheduling method for calculating the GHG emission reduction in a hypothetical competitive electricity industry due to the operation of a renewable energy-based power plant under CDM and compare the GHG emission reduction derived from the rigorous method with that obtained from the use of a simplified (i.e., standardized) method approved by the CDM-EB. A key finding of the paper is that depending upon the level of power demand, prices of electricity and input fuels, the simplified method can lead to either significant overestimation or substantial underestimation of emission reduction due to the operation of renewable energy-based power projects in a competitive electricity industry

    The efficiency for carbonization by slow pyrolysis is still low in the current method studied using rice straw in Thailand and cashewnut shell in Brazil, however direct heating process yields better char yield of 17% as compared to indirect heating with 15% process using horizontal metal drum kiln.where as vertical kiln were mainly used in Brazil. Higher yield is made possible from Brasilian cashew nut shell to make oil and char. Carbon and energy balance was also carried out and the results were compared for the direct and indirect process. Burning by indirect draft gives better results like more char, faster process. Direct draft gives less char, but higher quality (higher C and H2). Also a lot of straw is left unburnt in the direct draft kiln, because of bad temperature distribution and flow inside. The kiln design is found to be more suitable for indirect draft rather than direct draft. Both methods still give rice straw charcoal that has low calorific value with an output char LHV of 4337 kcal/kg as compared to fresh rice straw of 3412 kcal/kg. In the direct heating method output char is enriched to 45% with a still unburnt rice straw left out as compared to indirect heating method with carbon enrichment of 39%. There is a loss of 13% of carbon through the ash in the both the methods. The carbon content in the condensate is in the order of 18.5% for the indirect process as compared to 13.9% in the direct process due to less exhaust and carbon enrichment inside the kiln. There is a loss of 43% of carbon in the exhaust from indirect heating process as compared to direct heating process which is reduced to 26%. The energy balance predicts a heat loss of 14% in exhaust gases. A practical small scale slow pyrolysis project was developed to meet rural energy and heat requirements. to make the clean energy from waste resources possible by the joint project. (author)

  18. Understanding boys': thinking through boys, masculinity and suicide.

    Science.gov (United States)

    Mac An Ghaill, Mairtin; Haywood, Chris

    2012-02-01

    In the UK, the media are reporting increasing rates of childhood suicide, while highlighting that increasing numbers of pre-adolescent boys (in relation to girls) are diagnosed as mentally ill. In response, academic, professional and political commentators are explaining this as a consequence of gender. One way of doing this has been to apply adult defined understandings of men and masculinities to the attitudes and behaviours of pre-adolescent boys. As a consequence, explanations of these trends point to either 'too much' masculinity, such as an inability to express feelings and seek help, or 'not enough' masculinity that results in isolation and rejection from significant others, such as peer groups. Using a discourse analysis of semi-structured interviews with 28 children aged 9-13 (12 male, 16 females) and 12 school staff at a school in North East England, this article questions the viability of using normative models of masculinity as an explanatory tool for explaining boys' behaviours and suggests that researchers in the field of gender and suicide consider how boys' genders may be constituted differently. We develop this argument in three ways. First, it is argued that studies that use masculinity tend to reduce the formation of gender to the articulation of power across and between men and other men and women. Second, we argue that approaches to understanding boys' behaviours are simplistically grafting masculinity as a conceptual frame onto boy's attitudes and behaviours. In response, we suggest that it is important to re-think how we gender younger boys. The final section focuses specifically on the ways that boys engage in friendships. The significance of this section is that we need to question how notions of communication, integration and isolation, key features of suicide behaviours, are framed through the local production of friendships.

    2014-01-01

    Policy uncertainty can be a powerful deterrent to immediate investments. Based on panel data of 214 licenses to construct small run-of-the-river hydropower plants, we examine whether the prospect of a common Swedish–Norwegian market for green certificates (i.e., a renewable portfolio standard scheme) affected the timing of investments. Our results show that traditional utilities and other professional investors in the energy market acted in accordance with a real options investment rule, and the prospect of possible future subsidies delayed their investment decision. On the other hand, our results do not show that farmers and other non-professional investors incorporated timing considerations in their investment decisions. Rather, our results indicate that these investors behaved as if their investment opportunity is now-or-never, investing if the project is profitable according to a net present value investment rule, ignoring the opportunity to create additional value by waiting. The observed difference in behavior between professional and non-professional investors is interesting given the distributed nature of many renewable energy technologies, and can help planners and policymakers better understand the forces shaping the future market for electricity. - Highlights: • We examine whether the prospect of introducing subsidies delayed investments in hydropower. • We find that professional and non-professional investors behaved differently. • Professional investors explored the opportunity to create additional value by waiting. • Farmers behaved as if their investment opportunity was now-or-never. • These observations are interesting given the distributed nature of renewable energy technologies

By considering the gender divisions and the value of the VET programmes on the labour market, it explores what kind of problems boys have......The last two decades have seen an increasing political concern in the high dropout rates and low performance in education of boys compared to girls – at times in the form of a ‘moral panic’. This has also been the case in Denmark where ‘the boy problem’ in education now is placed high on the agenda...... to general education, but social and institutional processes of differentiation in the vocational schools place a significant group of students in a position where they have little chance of completing the programme. In the conclusion, some reflections are made on the effect of a recent reform of VET...

    No consensus exists regarding the precise role of testicular biopsy in prepubertal boys, although it is considered useful for assessing the potential consequences of undescended testes on fertility. Current scientific knowledge indicates that surgeons should broaden indications for this procedure...... for the preservation of fertility after gonadotoxic chemotherapy - even for prepubertal boys - are emerging. Cryopreservation of testicular tissue samples for the preservation of fertility - although still an experimental method at present - is appealing in this context. In our opinion, testicular biopsy...

    The Space Technology 5(ST5) payload was successfully carried into orbit on an OSC Pegasus XL launch vehicle, which was carried aloft and dropped from the OSC Lockheed L-1011 from Vandenberg Air Force Base March 22,2006, at 9:03 am Eastern time, 6:03 am Pacific time. In order to reach the completion of the development and successful launch of ST 5, the systems integration and test(I&T) team determined that a different approach was required to meet the project requirements rather than the standard I&T approach used for single, room-sized satellites. The ST5 payload, part of NASA's New Millennium Program headquartered at JPL, consisted of three micro satellites (approximately 30 kg each) and the Pegasus Support Structure (PSS), the system that connected the spacecrafts to the launch vehicle and deployed the spacecrafts into orbit from the Pegasus XL launch vehicle. ST5 was a technology demonstration payload, intended to test six (6) new technologies for potential use for future space flights along with demonstrating the ability of small satellites to perform quality science. The main technology was a science grade magnetometer designed to take measurements of the earth's magnetic field. The three spacecraft were designed, integrated, and tested at NASA Goddard Space Flight Center with integration and environmental testing occurring in the Bldg. 7-1 0-15-29. The three spacecraft were integrated and tested by the same I&T team. The I&T Manager determined that there was insufficient time in the schedule to perform the three I&T spacecraft activities in series used standard approaches. The solution was for spacecraft #1 to undergo integration and test first, followed by spacecraft #2 and #3 simultaneously. This simultaneous integration was successful for several reasons. Each spacecraft had a Lead Test Conductor who planned and coordinated their spacecraft through its integration and test activities. One team of engineers and technicians executed the integration of all

    The study aim was to objectively assess levels of sedentary time, light, moderate and vigorous physical activity (PA) among 10-12 year olds across five European countries and to examine differences in sedentary time and PA according to gender and country. 686 children (mean age = 11.6 ± 0.8 years, 53% girls, mean BMI = 19.0 ± 3.4 kg/m(2)) from Belgium, Greece, Hungary, the Netherlands and Switzerland wore Actigraph accelerometers and had at least 2 weekdays with minimum 10 h-wearing time and 1 weekend day with minimum 8 h-wearing time. Data were analyzed using multivariate analyses of covariance. Girls spent significantly more time sedentary (500 minutes/day) than boys (474 minutes/day) and significantly less time in light (267 minutes/day) and moderate-to-vigorous PA (32 minutes/day) than boys (284 minutes/day; 43 minutes/day respectively; p girls and 16.8% of the boys met moderate-to-vigorous PA recommendations of at least 60 minutes/day. Greek boys were more sedentary (510 minutes/day; all at p boys. Dutch girls were less sedentary (457 minutes/day; all at p girls. Swiss girls displayed more moderate-to-vigorous PA (43 minutes/day; at p girls. Large proportions of children across different European countries did not meet PA recommendations and spent a lot of time sedentary. Mean time spent in moderate-to-vigorous PA was significantly lower than the recommended 60 minutes. Obesity prevention programmes focusing on both decreasing sedentary time and increasing light, moderate and vigorous PA are needed for European children, particularly girls.

    Full Text Available Background: The problems of resources management (human, financial, time in multi-project companies are inherently complex and need to be addressed systematically, in both small and large organizations. Furthermore, there is a need for transparent communication and collaboration within the organization as well as with partnering organizations. There are many methodologies and tools supporting project management, which are themselves complex and are therefore not widely adopted, especially among small companies. Objectives: The aim of this paper is to analyse impact of the implementation of a flexible cloud-based project management information system (PMIS from the human resources, financial management, and collaboration points of view. Method: We have conducted a case study in a small Slovenian research and development company, that has implemented the 4PM PMIS. Results: The findings imply the importance of keeping the balance of the creative processes that are unstructured, rule free and even chaotic, with structured processes monitor and control. Conclusions: The results of the study suggest that the use of “4PM” in support of multi-project management improves human resources and financial management in a collaborative and transparent way when implemented in an open and highly motivated environment

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) presents the results of a preliminary project that examined how quality assurance methods can be used in the optimisation of small-scale hydropower projects. The aim of the project, to use existing know-how, experience and synergies, is examined. Discrepancies in quality and their effects on production prices were determined in interviews. The paper describes best-practice guidelines for the quality assurance of small-scale hydro schemes. A flow chart describes the various steps that have to be taken in the project and realisation work. Information collected from planners and from interviews made with them are presented along with further information obtained from literature. The results of interviews concerning planning work, putting to tender and the construction stages of these hydro schemes are presented and commented on. Similarly, the operational phase of such power plant is also examined, including questions on operation and guarantees. The aims of the follow-up main project - the definition of a tool and guidelines for ensuring quality - are briefly reviewed.

    In most research projects budget, staff and IT infrastructures are limiting resources. Especially for small-scale registries and cohort studies professional IT support and commercial electronic data capture systems are too expensive. Consequently, these projects use simple local approaches (e.g. Excel) for data capture instead of a central data management including web-based data capture and proper research databases. This leads to manual processes to merge, analyze and, if possible, pseudonymize research data of different study sites. To support multi-site data capture, storage and analyses in small-scall research projects, corresponding requirements were analyzed within the MOSAIC project. Based on the identified requirements, the Toolbox for Research was developed as a flexible software solution for various research scenarios. Additionally, the Toolbox facilitates data integration of research data as well as metadata by performing necessary procedures automatically. Also, Toolbox modules allow the integration of device data. Moreover, separation of personally identifiable information and medical data by using only pseudonyms for storing medical data ensures the compliance to data protection regulations. This pseudonymized data can then be exported in SPSS format in order to enable scientists to prepare reports and analyses. The Toolbox for Research was successfully piloted in the German Burn Registry in 2016 facilitating the documentation of 4350 burn cases at 54 study sites. The Toolbox for Research can be downloaded free of charge from the project website and automatically installed due to the use of Docker technology.

    The present study was conducted to establish cephalometric norms of Saudi boys based on the Steiners analysis, and to compare the results of the present study with similar studies conducted on other racial or ethnic groups. For this purpose, fifty-five healthy Saudi boys, with a mean age of 12.04 years, were selected from different schools of Riyadh. Female Saudis were not used for this study due to social restrictions with respect to the Kingdom's customs and traditions. Selection was made on the basis of normal occlusion, balanced and pleasing profile with no obvious facial asymmetry. None of the boys have undergone orthodontic treatment prior to this study. Lateral skull cephaiograms were taken and traced using a standardized technique. Each cephalogram was traced twice with a one week interval by the authors. All angular and linear measurements were calculated to the nearest 0.5 degree and 0.5 mm, respectively. Steiners method of cephalometric analysis was used to establish cephalometric norms. The result of the study demonstrated that the Saudi boys differed from other racial and ethnic groups in some skeletal and dental measurements. Generally, the Saudi boys revealed a more protrusive maxillary apical base and double dental protrusion. (author)

    Experimental Design Bureau of Mechanical Engineering (OKBM) specializes in the development of small and medium power reactors having different purposes. They include reactor plants for NPHPP, nuclear district heating power plants and propulsion plants. Small and medium power plants have simpler processes of electricity and heat production, less systems, simpler control algorithms and considerably enhanced inherent safety properties. These plants are mainly equipped with passive safety systems. These properties are especially characteristic for reactor plants of nuclear district heating power plants and HTG reactor plants. The designs of small and medium power plants actually provide a high degree of control automation which considerably reduces workload on the personnel in both normal and abnormal operation conditions. All this allows the reduction in personnel for small and medium power reactors if compared to high capacity reactor plants. But due to objective reasons the specific number of personnel (man/MW) for average and especially small capacity reactors considerably exceeds the value for high capacity reactor plants. At the same time one can propose a set of organization - technical measures allowing the increase in this value in future. Safety requirements imposed for small and average capacity reactors are the same or more strict than those for high capacity reactors. That's why the requirements to the training of personnel for such reactor plants are not allowed to be lowered if compared to the requirements imposed to the personnel of high capacity reactors.

    In order to evaluate physiological characteristics in young male ballet dancers, 27 boys (aged 9 to 16 years) who participated in a boys' dance course during the Kuopio Dance and Music Festival in June 1988 were studied. In general, the boys had started dancing at the age of 8.6 years and had been training for 4.1 years. They had, on average, three dancing sessions per week and the mean time spent on dancing was four hours per week. In the study, some anthropometric measurements were taken, the maximal oxygen uptake (VO2 max) was measured by a cycle ergometer test and the explosive strength and the mechanical power of lower extremities were evaluated by a jumping test. The results indicate that boys who train in ballet are in general moderately lean, have relatively small body size and a high degree of flexibility. The younger boys especially have only moderate aerobic power, but both explosive strength and mechanical power in leg muscles are good in ballet trained boys. PMID:2630002

    Carbon Capture and Storage (CCS) is moving toward large-scale commercial projects and the U.S. Department of Energy is supporting a new CarbonSAFE initiative to assist in the development of a 50 million tonnes geologic storage project. This type of large commercial CCS project will rely on lessons learned from smaller DOE CCS projects such as the Illinois Basin-Decatur Project (IBDP) and the Illinois Industrial Carbon Capture and Storage (IL-ICCS) Project located one mile north of IBDP. Over a three year period ending 2014 IBDP injected almost one million tonnes of CO2 into the Mt. Simon Sandstone, and the IL-ICCS project which commenced injection in 2017 will inject another four million tonnes over a four year period. The IBDP has recorded microseismic events within the study area through continuous downhole seismic monitoring before, during, and after injection. Monitoring shows that microseismicity increased during injection and originate not only in the Cambrian Mt. Simon Sandstone (the target reservoir), but also in the underlying Argenta clastics and deeper Precambrian igneous rocks as SW-NE elongate clusters aligned in strike to the maximum in situ stress direction. An interpretation of site 3D seismic reflection data suggests that much of the microseismicity is proximal to interpreted faults that extend from the basement up into the lowermost Mt. Simon strata. The faults proximally associated with microseismic activity are oriented parallel with respect to the maximum stress direction. The seismic monitoring of the IBDP indicate that the assessment of induced seismic potential associated with commercial-scale CCS requires not only identification of a suitable reservoir and its petrophysical characteristics, but also the extent and orientation of existing faults and their relation to regional stress orientation. Assessment of regional fault orientation using 3D seismic reflection data can be extremely useful to understanding the risks of induced seismicity

    Flash floods regularly cause severe socio-economic damage worldwide. In parallel, climate change is very likely to increase the number of such events, due to an increasing frequency of extreme precipitation events (EASAC 2013). Whereas recent work primarily addresses the resilience of large catchment areas, the major impact of hydro-meteorological extremes caused by heavy precipitation is on small areas. Those are very difficult to observe and predict, due to sparse monitoring networks and only few means for hydro-meteorological modelling, especially in small catchment areas. The objective of the EXTRUSO project is to identify and implement appropriate means to close this gap by an interdisciplinary approach, combining comprehensive research expertise from meteorology, hydrology, photogrammetry and geoinformatics. The project targets innovative techniques for achieving spatio-temporal densified monitoring and simulations for the analysis, prediction and warning of local hydro-meteorological extreme events. The following four aspects are of particular interest: 1. The monitoring, analysis and combination of relevant hydro-meteorological parameters from various sources, including existing monitoring networks, ground radar, specific low-cost sensors and crowdsourcing. 2. The determination of relevant hydro-morphological parameters from different photogrammetric sensors (e.g. camera, laser scanner) and sensor platforms (e.g. UAV (unmanned aerial vehicle) and UWV (unmanned water vehicle)). 3. The continuous hydro-meteorological modelling of precipitation, soil moisture and water flows by means of conceptual and data-driven modelling. 4. The development of a collaborative, web-based service infrastructure as an information and communication point, especially in the case of an extreme event. There are three major applications for the planned information system: First, the warning of local extreme events for the population in potentially affected areas, second, the support

  7. Three-Dimensional Thermal Modeling Analysis Of CST Media For The Small Ion Exchange Project

    International Nuclear Information System (INIS)

    Lee, S.; King, W.

    2011-01-01

    The Small Column Ion Exchange (SCIX) project is designed to accelerate closure of High Level Waste (HLW) tanks at the Savannah River Site (SRS). The SRS tanks store HLW in three forms: sludge, saltcake, and supernate. An in-tank ion exchange process is being designed to treat supernate and dissolved saltcake waste. Through this process, radioactive cesium from the salt solution is adsorbed into Crystalline Silicotitanate (CST) ion exchange media packed within a flow-through column. A packed column loaded with radioactive cesium generates significant heat from radiolytic decay. The waste supernate solution within the ion exchange bed will boil around 120 C. Solution superheating above the boiling point within the column could lead to violent hazardous energy releases. System heating from loaded CST is also of concern in other process modules, such as the waste tank. Due to tank structural integrity concerns, the wall temperature limit for the SRS waste tanks is 100 C. The transfer of cesium-loaded CST to the tank could result in localized hot spots on the tank floor and walls which may exceed this limit. As a result, thermal modeling calculations have been conducted to predict the maximum temperatures achievable both in the column and in the waste tank. As specified in the associated Technical Task Plan, one objective of the present work was to compute temperature distributions within the ion exchange column module under accident scenarios including loss of salt solution flow through the bed and loss of coolant system flow. The column modeling domain and the scope of the calculations in this case were broadened relative to previous two-dimensional calculations to include vertical temperature distributions within the packed bed of ion exchange media as well as the upper column plenum region containing only fluid. The baseline design conditions and in-column modeling domain for the ion-exchange column module are shown in Figure 1. These evaluations assumed the maximum

    Corporate motives and strategies of both investing and hosting country affect the outcomes of a clean development mechanism (CDM) project-who introduces what technology to whom-and result in large differences in economic viability and the CO 2 emission reductions. This is particularly true for steel industry in which steel making consists of many detailed and complex processes, a given strategy could produce cumulative effects of the individual technologies used, leading to large energy savings overall. The objective of this study is to demonstrate some analytical methods that can be used to quantitatively evaluate the impacts of technology selection on the profit performance of CDM projects. Specifically, in this study we analyze a CDM project to introduce energy saving technology from Japan to a small steel manufacturer in China's Shandong Province, and conduct a simulation of the quantitative relationships between various technology options and profitability. Based on these results, we examine the environmental and economic significance of technology selection for CDM projects. To take this further, we then reconsider the profitability of a project as typical FDI activity (i.e., without the CDM), and by comparing this outcome with the CDM case, we clarify the significance and potential of the CDM

  15. Evaluation of an Unsuccessful Brook Trout Electrofishing Removal Project in a Small Rocky Mountain Stream.

    Energy Technology Data Exchange (ETDEWEB)

    2006-01-26

    In the western United States, exotic brook trout Salvelinus fontinalis frequently have a deleterious effect on native salmonids, and biologists often attempt to remove brook trout from streams by means of electrofishing. Although the success of such projects typically is low, few studies have assessed the underlying mechanisms of failure, especially in terms of compensatory responses. A multiagency watershed advisory group (WAG) conducted a 3-year removal project to reduce brook trout and enhance native salmonids in 7.8 km of a southwestern Idaho stream. We evaluated the costs and success of their project in suppressing brook trout and looked for brook trout compensatory responses, such as decreased natural mortality, increased growth, increased fecundity at length, and earlier maturation. The total number of brook trout removed was 1,401 in 1998, 1,241 in 1999, and 890 in 2000; removal constituted an estimated 88% of the total number of brook trout in the stream in 1999 and 79% in 2000. Although abundance of age-1 and older brook trout declined slightly during and after the removals, abundance of age-0 brook trout increased 789% in the entire stream 2 years after the removals ceased. Total annual survival rate for age-2 and older brook trout did not decrease during the removals, and the removals failed to produce an increase in the abundance of native redband trout Oncorhynchus mykiss gairdneri. Lack of a meaningful decline and unchanged total mortality for older brook trout during the removals suggest that a compensatory response occurred in the brook trout population via reduced natural mortality, which offset the removal of large numbers of brook trout. Although we applaud WAG personnel for their goal of enhancing native salmonids by suppressing brook trout via electrofishing removal, we conclude that their efforts were unsuccessful and suggest that similar future projects elsewhere over such large stream lengths would be costly, quixotic enterprises.

    Small Hydro Power is a good option of generation mainly when they are located close to the consumers, because they demand smaller absolute value of invested capital and smaller time of maturation. Besides, the great repressed demand, mainly in the schedules of point, and the recovery of the values of the tariffs has been showed to private investor for this type of central. This paper develops a new method that allows to give agility to the study of small hydropower operating in cascade form in order to optimize the cost-benefit relationship of the enterprise. Approaches are presented for the evaluation of this type of system, the methodology of partition of falls and the proposed model. A case study, in which this method is applied, is shown at the end of this work. (author)

    Electric propulsion and autonomy are technology frontiers that offer tremendous potential to achieve low operating costs for small-aircraft. Such technologies enable simple and safe to operate vehicles that could dramatically improve regional transportation accessibility and speed through point-to-point operations. This analysis develops an understanding of the potential traffic volume and National Airspace System (NAS) capacity for small on-demand aircraft operations. Future demand projections use the Transportation Systems Analysis Model (TSAM), a tool suite developed by NASA and the Transportation Laboratory of Virginia Polytechnic Institute. Demand projections from TSAM contain the mode of travel, number of trips and geographic distribution of trips. For this study, the mode of travel can be commercial aircraft, automobile and on-demand aircraft. NASA's Airspace Concept Evaluation System (ACES) is used to assess NAS impact. This simulation takes a schedule that includes all flights: commercial passenger and cargo; conventional General Aviation and on-demand small aircraft, and operates them in the simulated NAS. The results of this analysis projects very large trip numbers for an on-demand air transportation system competitive with automobiles in cost per passenger mile. The significance is this type of air transportation can enhance mobility for communities that currently lack access to commercial air transportation. Another significant finding is that the large numbers of operations can have an impact on the current NAS infrastructure used by commercial airlines and cargo operators, even if on-demand traffic does not use the 28 airports in the Continental U.S. designated as large hubs by the FAA. Some smaller airports will experience greater demand than their current capacity allows and will require upgrading. In addition, in future years as demand grows and vehicle performance improves other non-conventional facilities such as short runways incorporated into

    At the time of this study there were about 160 small and medium sized nuclear power reactors (referred to as SMRs) in operation worldwide, and about 25 more under construction. Operation and maintenance costs for operating SMRs represent a substantial portion of the cost of electricity produced. Of these costs, the direct and indirect cost of staff represents the major cost component. In recent years, particularly since 1990, there has been increased interest in SMRs by many developing countries wishing to take advantage of nuclear power and several small and medium reactor designs are in various stages of development. To enhance the economic competitive position of SMRs relative to alternative methods of electricity generation, it is essential to ensure that new SMRs can be operated reliably and efficiently using the optimum number of staff. This publication reviews the lessons learned from the reactor operation, and the insights gained through the design of new SMRs, with a view to optimizing staffing in order to improve overall plant economics without compromising safety.This publication is intended to evaluate the estimated staffing size of various SMRs, the staff qualification and training required for the operation of future SMRs. and the key issues which impact the staffing requirements that should be considered in the development and deployment of future SMRs

    Full Text Available This study uses a risk management perspective to analyze compliance costs arising from overlapping service tax (ST jurisdictions. We study the case of an engineering company providing services to the Companhia de Saneamento Básico do Estado de São Paulo [São Paulo State Sanitation Company] – SABESP, a public entity. The engineering company was contracted under public law 8.666/93, to provide engineering service in several townships in São Paulo’s metropolitan area. Because the laws governing bidding do not permit later modification in price or provider, subsequent double taxation by one municipality cut into the firm’s margins, and should other local governments follow suit, multiple taxation would render the contract untenable for the provider. Our paper models the impact of conflicting jurisdictions on administrative burden, psychological costs and profit constriction and discusses project management techniques for decision making and management in similar situations.

    Full Text Available Two satellites of the INTERBALL project were launched on 3 August 1995. The main goals of the present paper are (1 to give a brief information about the VDP plasma device onboard the INTERBALL-1 satellite, (2 to present the Faradays cup data taken in different magnetospheric regions and (3 to expose first results of the two satellite measurements of the magnetopause motion. The presented data illustrate magnetopause crossings as seen by two satellites when separated by about ~ 1000 km. This separation combined with the Faraday's cup time resolution allows to estimate the velocity of the magnetopause and to reconstruct a possible structure of the boundary. Simultaneous measurement of the magnetic field supports the interpretation of the observed ion fluxes as a signature of the wavy motion of the boundary.

    Sandia has recently completed the flight certification test series for the Multi-Spectral Thermal Imaging satellite (MTI), which is a small satellite for which Sandia was the system integrator. A paper was presented at the 16th Aerospace Testing Seminar discussing plans for performing the structural dynamics certification program for that satellite. The testing philosophy was originally based on a combination of system level vibroacoustic tests and component level shock and vibration tests. However, the plans evolved to include computational analyses using both Finite Element Analysis and Statistical Energy Analysis techniques. This paper outlines the final certification process and discuss lessons learned including both things that went well and things that should/could have been done differently.

    Full Text Available An Advanced Water Treatment Plant (AWTP for potable water recycling in Davis Station Antarctica was trialed using secondary effluent at Selfs Point in Hobart, Tasmania, for nine months. The trials demonstrated the reliability of performance of a seven barrier treatment process consisting of ozonation, ceramic microfiltration (MF, biologically activated carbon, reverse osmosis, ultra-violet disinfection, calcite contactor and chlorination. The seven treatment barriers were required to meet the high log removal values (LRV required for pathogens in small systems during disease outbreak, and on-line verification of process performance was required for operation with infrequent operator attention. On-line verification of pathogen LRVs, a low turbidity filtrate of approximately 0.1 NTU (Nephelometric Turbidity Unit, no long-term fouling and no requirement for clean-in-place (CIP was achieved with the ceramic MF. A pressure decay test was also reliably implemented on the reverse osmosis system to achieve a 2 LRV for protozoa, and this barrier required only 2–3 CIP treatments each year. The ozonation process achieved 2 LRV for bacteria and virus with no requirement for an ozone residual, provided the ozone dose was >11.7 mg/L. Extensive screening using multi-residue gas chromatography–mass spectrometry (GC–MS and liquid chromatography–mass spectrometry (LC–MS database methods that can screen for more than 1200 chemicals found that few chemicals pass through the barriers to the final product and rejected (discharge water streams. The AWTP plant required 1.93 kWh/m3 when operated in the mode required for Davis Station and was predicted to require 1.27 kWh/m3 if scaled up to 10 ML/day. The AWTP will be shipped to Davis Station for further trials before possible implementation for water recycling. The process may have application in other small remote communities.

    Rangitoto is a small basaltic shield volcano representing the most recent and most voluminous episode of volcanism in the Auckland Volcanic Field, New Zealand. Auckland City is built on the field, and hence, Rangitoto's importance in hazard-risk modelling. The symmetrical edifice, ~6 km wide and 260 m high, has volume of 1.78 km3. It comprises summit scoria cones and a lava field. However, the lack of deep erosion dissection has prevented the development of an eruptive stratigraphy. Previous studies suggested construction in a relatively short interval at 550-500 yrs BP. However, microscopic tephra have been interpreted as evidence of intermittent activity from 1498 +/- 140 to 504 +/- 6 yrs BP, a longevity of 1000 years. A 150-m-deep hole was drilled through the edifice in February 2014 to obtain a continuous core record. The result is an unparalleled stratigraphy of the evolution of a small shield volcano. The upper 128 m of core comprises at least 27 lava flows with thicknesses in the range 0.3-15 m, representing the main shield-building phase. Underlying marine sediments are interbedded with 8 m of pyroclastic lapilli, and a thin lava flow, representing the explosive phreatomagmatic birth of the volcano. Preliminary geochemical analyses reveal suite of relatively uniform transitional basalts (MgO = 8.1 to 9.7 wt %). However, 4 compositional groups are distinguished that were erupted in sequential order. High-MgO magmas were erupted first, followed by a two more heterogeneous groups displaying differentiation trends with time. Finally, distinct low-MgO basalts were erupted. Each magma type appears to represent a new magma batch. The core places the magma types in a time series, which can be correlated to the surface lava field. Hence, allowing a geometrical reconstruction of the shield growth. Additional petrologic investigations are providing insight to magmatic ascent processes, while radiocarbon and paleomagnetic secular variation studies will reveal the

    Moderate-to-vigorous physical activity (MVPA) plays an important role in childhood overweight prevention. Sedentary time appears to be independently associated with overweight, but most research has been done in adults. The objective of this study were to identify subgroups of children based on their MVPA and sedentary time, and explore differences in body mass index (BMI), waist circumference and overweight prevalence between among these subgroups. A sample of 766 10- to 12-year-old children (52.9% girls, 11.6 ± 0.8 years) were recruited from Hungary (n = 158), Belgium (n = 111), the Netherlands (n = 113), Greece (n = 169) and Switzerland (n = 215). Children wore an accelerometer to measure MVPA and sedentary time. Cluster analysis revealed four clusters in both gender groups showing an unhealthy pattern (low MVPA/high sedentary time), a healthy pattern (high MVPA/low sedentary time), a low mixed pattern (low MVPA/low sedentary time) and a moderate to high mixed pattern (moderate to high MVPA/moderate sedentary time). In girls, the high MVPA/low sedentary time cluster had a significantly lower BMI (P ≤ 0.05), a lower waist circumference (P ≤ 0.01) and the lowest percentage of overweight (P ≤ 0.10) compared with the other three clusters. In boys, both clusters with higher activity levels had a significantly lower BMI (P ≤ 0.001) and waist circumference (P ≤ 0.001) than the two low activity clusters, independent of sedentary time. Engagement in more MVPA and less sedentary time is associated with a more favourable weight status among 10- to 12-year-old girls. Among boys, MVPA seems most important for weight status, while sedentary time appears to be less relevant. © 2012 The Authors.

    Energy Technology Data Exchange (ETDEWEB)

    1979-02-01

    Solid, liquid, and gaseous by-products and wastes are generated during coal storage and processing, gasification, and gas cleanup. Recovery systems have been designed to collect and utilize by-products. Wastes will be placed in storage areas designed to prevent release of the materials to the environment. The coal gasification plant along with the solid waste disposal area will occupy approximately 115 acres. To prevent, to the fullest extent possible, degradation of groundwater and surface water resources, the coal stockpile, landfill, collection pond, settling basin, and drainage ditches will be constructed to prevent the seepage of potential contaminants into groundwater or the drainage of runoff into surface waters. Cooling water is the primary water requirement of the project. None of the water utilized in the gasification plant will be released into the area surface water system, but will be either recycled or directed into the settling basin. The gasification facility has the potential of emitting a broad spectrum of pollutants into the atmosphere. However, effective emission control procedures such as off-gas recycling, hydrogen sulfide removal, particulate removal, and flaring will be applied to minimize the plant's emissions. The necessity of monitoring the more exotic pollutants such as acid gases, trace elements, metal carbonyls, and a multitude of organic compounds, will be determined as the gasification facility becomes more of a reality and the latest literature and research developments can be surveyed to evaluate the emission rates, biological significance, and monitoring techniques for these pollutants.

    Full Text Available The smart and resilient city evolves by slow procedures of mutation without radical changes, increasing the livability of its territory. The value of the city center in a Smart City can increase through urban lighting systems: its elements on the territory can collect and convey data to increase services to city users; the electrical system becomes the so-called Smart Grid. This paper presents a study of smart lighting for a small town, a touristic location inside a nature reserve on the Italian coast. Three different approaches have been proposed, from minimal to more invasive interventions, and their effect on the territory has been investigated. Based on street typology and its surroundings, the work analyzes the opportunity to introduce smart and useful services for the citizens starting from a retrofitting intervention. Smart city capabilities are examined, showing how it is possible to provide new services to the cities through ICT (Information and Communication Technology without deep changes and simplifying the control of basic city functions. The results evidence an important impact on annual energy costs, suggesting smart grid planning not only for metropolis applications, but also in smaller towns, such as the examined one.

    Head Up Display (HUD) is being applied to automobile. HUD displays information as far virtual image on the windshield. Existing HUD usually displays planar information. If the image corresponding to scenery on the road like Augmented Reality (AR) is displayed on the HUD, driver can efficiently get the information. To actualize this, HUD covering large viewing field is needed. However existing HUD cannot cover large viewing field. Therefore we have proposed system consisting of projector and many small diameter convex lenses. However observed virtual image has blurring and distortion . In this paper, we propose two methods to reduce blurring and distortion of images. First, to reduce blurring of images, distance between each of screen and lens comprised in lens array is adjusted. We inferred from the more distant the lens from center of the array is more blurred that the cause of blurring is curvature of field of lens in the array. Second, to avoid distortion of images, each lens in the array is curved spherically. We inferred from the more distant the lens from center of the array is more distorted that the cause of distortion is incident angle of ray. We confirmed effectiveness of both methods.

    The project of small watercourses restoration in the northern part of the Volga-Akhtuba floodplain is considered together with the aim of increasing the watering of the territory during small and medium floods. The topography irregularity, the complex structure of the floodplain valley consisting of large number of small watercourses, the presence of urbanized and agricultural areas require careful preliminary analysis of the hydrological safety and efficiency of geographically distributed project activities. Using the digital terrain and watercourses structure models of the floodplain, the hydrodynamic flood model, the analysis of the hydrological safety and efficiency of several project implementation strategies has been conducted. The objective function values have been obtained from the hydrodynamic calculations of the floodplain territory flooding for virtual digital terrain models simulating alternatives for the geographically distributed project activities. The comparative efficiency of several empirical strategies for the geographically distributed project activities, as well as a two-stage exact solution method for the optimization problem has been studied.

  1. Thermal Modeling Analysis Of CST Media In The Small Column Ion Exchange Project

    International Nuclear Information System (INIS)

    Lee, S.

    2010-01-01

    Models have been developed to simulate the thermal characteristics of Crystalline Silicotitanate (CST) ion exchange media fully loaded with radioactive cesium in a column configuration and distributed within a waste storage tank. This work was conducted to support the Small Column Ion Exchange (SCIX) program which is focused on processing dissolved, high-sodium salt waste for the removal of specific radionuclides (including Cs-137, Sr-90, and actinides) within a High Level Waste (HLW) storage tank at the Savannah River Site. The SCIX design includes CST columns inserted and supported in the tank top risers for cesium removal. Temperature distributions and maximum temperatures across the column were calculated with a focus on process upset conditions. A two-dimensional computational modeling approach for the in-column ion-exchange domain was taken to include conservative, bounding estimates for key parameters such that the results would provide the maximum centerline temperatures achievable under the design configurations using a feed composition known to promote high cesium loading on CST. One salt processing scenario includes the transport of the loaded (and possibly ground) CST media to the treatment tank floor. Therefore, additional thermal modeling calculations were conducted using a three-dimensional approach to evaluate temperature distributions for the entire in-tank domain including distribution of the spent CST media either as a mound or a flat layer on the tank floor. These calculations included mixtures of CST with HLW sludge or loaded Monosodium Titanate (MST) media used for strontium/actinide sorption. The current full-scale design for the CST column includes one central cooling pipe and four outer cooling tubes. Most calculations assumed that the fluid within the column was stagnant (i.e. no buoyancy-induced flow) for a conservative estimate. A primary objective of these calculations was to estimate temperature distributions across packed CST beds

    The aim of this paper is to propose a method for valuation of assets of small hydroelectric plants in different stages of maturation. To this end, we adopted the principle of risk premium, associated with a portion of the profitability of the project (internal rate of return-IRR) in every stage of development. In other words: the more mature the project, the lower your risk and consequently lower the corresponding premium, adopting as a total prize the IRR expected to the project.

    1985-01-01

    Fundamental studies have been made on the application of mathematical programming to the reconstruction of tomographic images from projections of a small number of views without requiring any circular symmetry nor periodicity. Linear programming and quadratic programming were applied to minimize the quadratic sum of the residue and to finally obtain optimized reconstruction images. The mathematical algorithms were verified by the method of computer simulation, and the relationship between the number of picture elements and the number of iterations necessary for convergence was also investigated. The methods of linear programming and quadratic programming require fairly simple mathematical procedures, and strict solutions can be obtained within a finite number of iterations. Their only draw back is the requirement of a large quantity of computer memory. But this problem will be desolved by the advent of large fast memory devices in the near future. (Aoki, K.)

  4. Designing Agricultural Development Projects for the Small Scale Farmers: Some Lessons from the World Bank Assistance Small Holder Oil Palm Development Scheme in Nigeria

    Orewa, S. I.

    The study was carried out to investigate farmers reasons for intercropping their oil palm farms with food and other cash crops rather than the sole oil palm planting arrangement specified for participation in the World Bank Assistance Smallholder Oil Palm development project financed during the 1975-83 period. The study was conducted at the Ekuku-Agbor Tree Crop Unit Zone (to the East) and Mosogar Tree Crop Unit Zone (to the Southwest) of the old Bendel State of Nigeria. A total of 35 oil palm farmers were randomly selected from each zone for the study. The study tried to identify the size of oil palm cultivated, types of food and cash crops planted and the proportion consumed and sold and the sufficiency of labour for various farm activities. The study showed that the average oil palm farm size at Ekuku-Agbor zone was smaller (about 1.57 ha) and more fragmented while for Mosogar zone it was 2.28 ha. However a greater percentage (over 65%) of the farms at both locations were within 0.01-2.00 ha farm size range which could be said to be relatively small. The study revealed that among other factors the farmers desire to ensure adequate family food needs which equates to food security and some cash to meet regular family financial needs necessitated their intercropping of the oil palm farms. Others include the need to maximize the returns from the use of labour which they considered a major limiting factor in farm maintenance and to take advantage of the relative high unit price of cassava and its products that prevailed then by cultivating on any available land space including the palm plantations and thereby increasing their farm income.

    Full Text Available PURPOSE: The aim of this study was to evaluate the comprehension and acceptance of HPV vaccination in parents of adolescent boys aged 11 to 15 years. METHODS: A cross-sectional survey was conducted by means of questionnaires sent directly to the homes of all families with young males aged between 11 and 15, residents of three municipalities of the Province of Brescia, Italy. The documentation also contained an informative leaflet summarizing the HPV-related disease characteristics, the burden of disease and the available strategies for prevention and treatment, illustrating the rationale of vaccination and describing the project and its phases. The questionnaire included questions on demographic data, acceptance and motivations for HPV vaccination. The collected data was analyzed using descriptive statistics. At the end of the study, parents who received the questionnaires were also offered the possibility of vaccinating their male sons for free. RESULTS: From a total of 1072 questionnaires sent, 161 where returned from the three selected municipalities (average response rate 15%; 97% of adolescent males involved in the study were Italian and 91% Catholic; 97% of parents declared themselves to be willing to vaccinate their sons: the principal motivation given (92% was prevention of the disease, cancerous or not, related to viral infection. Among the respondents not willing to vaccinate their sons, the motivation was lack of information about the vaccine and the disease. At the end of the study, around 71 boys were vaccinated. DISCUSSION: To our knowledge, this is the first survey in Italy exclusively conducted on parents of adolescent males about the acceptability and feasibility of vaccination against HPV: a very high percentage of respondents was favorable to accept the vaccination for their sons, the main motivation being the fact that parents considered protecting their sons from HPV-related diseases highly important.

    2003-09-01

    Full Text Available Abstract Background Subtractive hybridization methods are valuable tools for identifying differentially regulated genes in a given tissue avoiding redundant sequencing of clones representing the same expressed genes, maximizing detection of low abundant transcripts and thus, affecting the efficiency and cost effectiveness of small scale cDNA sequencing projects aimed to the specific identification of useful genes for breeding purposes. The objective of this work is to evaluate alternative strategies to high-throughput sequencing projects for the identification of novel genes differentially expressed in sunflower as a source of organ-specific genetic markers that can be functionally associated to important traits. Results Differential organ-specific ESTs were generated from leaf, stem, root and flower bud at two developmental stages (R1 and R4. The use of different sources of RNA as tester and driver cDNA for the construction of differential libraries was evaluated as a tool for detection of rare or low abundant transcripts. Organ-specificity ranged from 75 to 100% of non-redundant sequences in the different cDNA libraries. Sequence redundancy varied according to the target and driver cDNA used in each case. The R4 flower cDNA library was the less redundant library with 62% of unique sequences. Out of a total of 919 sequences that were edited and annotated, 318 were non-redundant sequences. Comparison against sequences in public databases showed that 60% of non-redundant sequences showed significant similarity to known sequences. The number of predicted novel genes varied among the different cDNA libraries, ranging from 56% in the R4 flower to 16 % in the R1 flower bud library. Comparison with sunflower ESTs on public databases showed that 197 of non-redundant sequences (60% did not exhibit significant similarity to previously reported sunflower ESTs. This approach helped to successfully isolate a significant number of new reported sequences

    The discourse on Black boys tends to suggest that Black boys are in complete peril. We begin with evidence that Black boys are excelling in certain contexts (i.e., in certain states, in certain schools, and in certain courses). We then discuss the ways in which the narratives used by parents, teachers, and Black boys themselves may serve to further reinforce views that Black boys are beyond hope. Research on Black parents suggests that they tend to view their sons as vulnerable and have lower expectations for sons than for daughters. Studies of teachers show that they tend to view Black boys as unteachable, as social problems, and as scary. Research on Black boys shows that they are sometimes complicit in supporting these narratives by engaging in negative or ste reotypical behavior. We also include recent research that includes counter-narratives of Black boys. We end with suggestions for future research.

    CNC cutting machines have become essential tools for designers and architects enabling rapid prototyping, model-building and production of high quality components. Designers often cut from new materials, discarding the irregularly shaped remains. We introduce ProjecTables, a visual augmented...... reality system for interactive packing of model parts onto sheet materials. ProjecTables enables designers to (re)use scrap materials for CNC cutting that would have been previously thrown away, at the same time supporting aesthetic choices related to wood grain, avoiding surface blemishes, and other...... relevant material properties. We conducted evaluations of ProjecTables with design students from Aarhus School of Architecture, demonstrating that participants could quickly and easily place and orient model parts reducing material waste. Contextual interviews and ideation sessions led to a deeper...

    Animal and human adult studies reveal a contribution of serotonin to behavior regulation. Whether these findings apply to children is unclear. The present study investigated serotonergic functioning in boys with a history of behavior regulation difficulties through a double-blind, acute tryptophan supplementation procedure. Participants were 23 boys (age 10 years) with a history of elevated physical aggression, recruited from a community sample. Eleven were given a chocolate milkshake supplemented with 500 mg tryptophan, and 12 received a chocolate milkshake without tryptophan. Boys engaged in a competitive reaction time game against a fictitious opponent, which assessed response to provocation, impulsivity, perspective taking, and sharing. Impulsivity was further assessed through a Go/No-Go paradigm. A computerized emotion recognition task and a staged instrumental help incident were also administered. Boys, regardless of group, responded similarly to high provocation by the fictitious opponent. However, boys in the tryptophan group adjusted their level of responding optimally as a function of the level of provocation, whereas boys in the control group significantly decreased their level of responding towards the end of the competition. Boys in the tryptophan group tended to show greater perspective taking, tended to better distinguish facial expressions of fear and happiness, and tended to provide greater instrumental help to the experimenter. The present study provides initial evidence for the feasibility of acute tryptophan supplementation in children and some effect of tryptophan supplementation on children's behaviors. Further studies are warranted to explore the potential impact of increased serotonergic functioning on boys' dominant and affiliative behaviors.

    Full Text Available Study region: Small watersheds (O[25 km2] in the mountain regions of southern California comprise the study region. Study focus: This paper examines changes in flash flood occurrence in southern California resulting from projected climatic change. The methodology synthesizes elements of meteorological modeling, hydrology and geomorphology into an integrated modeling approach to define flash flood occurrence in a systematic and consistent way on a regional basis with high spatial and temporal resolution appropriate for flash flooding. A single climate model with three-dimensional atmospheric detail was used as input to drive simulations for historical and future periods. New hydrological insights for the region: Results indicate an increase in flash flood occurrence for the study region. For two distributed hydrologic models employed, the increase in flash flood occurrence frequency is on average between 30% and 40%. Regional flash flood occurrence is characterized by near saturation of the upper soil layer, and wider ranges in lower soil layer saturation and in precipitation. Overall, a decrease in the total number of precipitation events was found, although with increased precipitation intensity, increased event duration, and higher soil saturation conditions for the 21st century. This combination could signify more hazardous conditions, with fewer precipitation events but higher rainfall intensity and over soils with higher initial soil moisture saturation, leading to more frequent occurrence of flash floods.

    The problem of the high prevalence of smoking among girls and young women is of great concern. In an attempt to identify the factors which influence girls and boys respectively to attempt smoking, the study examines social background, advertising and brand awareness, knowledge, teaching and personal beliefs in conjunction as predictors of smoking. In this study which involved the administration of identical pre- and post-test questionnaires to a sample of boys and girls aged 12 and 13 years, nine variables expressed by never-smokers at pre-test stage were assessed as predictors of immediate future smoking. The two tests were administered 4 months apart to 1125 boys and 1213 girls in northern England. The nine variables included were parental smoking, best friends' smoking, perceived positive values of smoking, perceived negative values of smoking, correct health knowledge, cigarette-brand awareness, having a favourite cigarette advertisement, having a cigarette-brand sponsored sport in four top favourites on television. One group received teaching about smoking between the pre- and post-tests and this was also included as a variable. For boys, no variable investigated had any consistently statistically significant correlation with the uptake of smoking. The most important predictor of smoking for boys, having a best friend who smoked, was significant on application of the chi 2 test (P 0.037), although it was non-significant when included singly in a logistic regression model (0.094); the discrepancy was probably due to the small number of best friends known to smoke. For girls, four variables were found to be significant predictors of smoking when included singly in a logistic regression.(ABSTRACT TRUNCATED AT 250 WORDS)

    This report is intended to help NASA program and project managers incorporate Glenn Research Center Small Business Innovation Research/Small Business Technology Transfer (SBIR)/(STTR) technologies into NASA Human Exploration and Operations Mission Directorate (HEOMD) programs and projects. Other Government and commercial project managers can also find this useful. Introduction Incorporating Small Business Innovation Research (SBIR)-developed technology into NASA projects is important, especially given the Agency's limited resources for technology development. The SBIR program's original intention was for technologies that had completed Phase II to be ready for integration into NASA programs, however, in many cases there is a gap between Technology Readiness Levels (TRLs) 5 and 6 that needs to be closed. After SBIR Phase II projects are completed, the technology is evaluated against various parameters and a TRL rating is assigned. Most programs tend to adopt more mature technologies-at least TRL 6 to reduce the risk to the mission rather than adopt TRLs between 3 and 5 because those technologies are perceived as too risky. The gap between TRLs 5 and 6 is often called the "Valley of Death" (Figure 1), and historically it has been difficult to close because of a lack of funding support from programs. Several papers have already suggested remedies on how to close the gap (Refs. 1 to 4).

    Full Text Available In this paper the author summarizes several life history case studies of adolescent boys who were identified at school as “wimps” and who eventually engaged in various forms of sexual violence. Such boys rarely are— if at all—discussed in the childhood, education and feminist literatures on sexual violence. The life stories reveal the interrelationship among inschool bullying, reflexivity, embodied structured action, and the social construction of heteromasculinities in the commission of sexual violence by subordinated boys. The author concludes by considering the implications the research has to the evolving discourses on social scientific conceptualizations of reflexive embodiment and heteromasculinities.

    2016-08-01

    This study explored the extent to which sexting represents a problematic behavior in early and late adolescence. Using data from the EU Kids Online II project (17,016 participants aged 11-16 from 25 European countries, 49.7% boys), multilevel logistic regression analyses were conducted separately for four groups: younger girls, older girls, younger boys, and older boys. Irrespective of age and gender, sexting was associated with emotional problems and alcohol use. Its effect decreased in older adolescents, except for emotional difficulties, which remained relatively high in older boys. Vaginal sex was associated with sexting in both younger and older boys while, in girls, the association was observed only in the older group. Younger boys with higher self-efficacy were more likely to send sexts than those with lower self-efficacy. Although sexting is associated with psychological challenges and other types of risk behavior, sexting in some younger boys may not necessarily represent problematic behavior.

    1991-01-01

    As very little is known about boys' subjective and emotional experiences when going through puberty, the qualitative research method of grounded theory was used in this study to address the question: "What is the experience of the physical maturational changes in male adolescents?" A Basic Social Psychological Process emerged, Minimizing Embarrassment, with four stages: waiting for the change, noticing the change, dealing with the change, and feeling comfortable with the change. Boys developed expectations from listening to others, by looking at older males, and by wondering and imagining what the changes would eventually be like for them. After developing these expectations, they compared their physical changes to others and to their own expectations. If the boys felt they were different from their peers, they worried about this difference. They used strategies such as avoiding, pretending, and joking to avoid embarrassment or to deal with embarrassing situations. If the boys felt they were "normal," they accepted the fact that they were maturing properly.

    The City of North Myrtle Beach SC has erected three small-scale wind turbines for educational purposes. These turbines are tied directly into the local power grid. This allows for a unique study opportunity through which to teach renewable energy strategies. The study focuses on inter-site variability spread out over four miles of beach. Each location is subject to different wind fields responding to local structures. The study focuses on inter-site variability to cross reference energy production with the wind and weather conditions. Public and K-12 outreach is a primary objective of the program. Using demonstration turbines and by analyzing the wind, weather and site conditions outreach efforts are focused on highlighting renewable energy concepts. This also allows focus on STEM disciplines and critical thinking in analyzing data to compare the sites and different turbine production. Engaging in the STEM disciplines the projects crosses over science, technology, engineering, and mathematical boundaries creating an interdisciplinary scientific experience for students. In addition, this allows for introduction of techniques and developing technologies. It also allows students to consider challenges and possible solutions to issues of increased power production and cost efficiency. Through connecting the touchstone of experiential learning; a hands-on experience actively engages students in experimental application and problem solving. By looking locally at renewable energy in Horry County South Carolina students are engaged in seeing how projects impact science and economic development in the region. The Congressional Research Service (CRS) Report for Congress reports a considerable need expand and enhance the o preparation of students, teachers and practitioners in the areas of science, technology, engineering and mathematics.

    Ellen De Schepper

    2015-09-01

    Full Text Available The two core objectives of the Clean Development Mechanism (CDM are cost-effective emission reduction and sustainable development. Despite the potential to contribute to both objectives, solar projects play a negligible role under the CDM. In this research, the greenhouse gas mitigation cost is used to evaluate the economic and environmental performances of small-scale rural photovoltaic solar projects. In particular, we compare the use of absolute and relative mitigation costs to evaluate the attractiveness of these projects under the CDM. We encourage the use of relative mitigation costs, implying consideration of baseline costs that render the projects profitable. Results of the mitigation cost analysis are dependent on the baseline chosen. To overcome this drawback, we complement the analysis with a multi-objective optimization approach, which allows quantifying the trade-off between economic and environmental performances of the optimal technologies without requiring a baseline.

    NPP SMR is one alternative to overcome the Outside Java Bali region's dependence on diesel power plant. One crucial issue in the NPP project (including SMR) would be financing, associated with the capital-intensive nature of the project. In addition, the SMR NPP project also be vulnerable in occurrence of some uncertainties. Therefore, this study aimed to analyze the financial feasibility of SMR NPP project by accommodating the possibility of the uncertainties. The methodology used is probabilistic analysis which was performed by Monte Carlo technique. This technique simulates the relationship between the uncertainty variables with financial feasibility indicators. The results showed that in probabilistic approach, SMR NPP project is considered feasible on the 'most probable value' of electricity selling price of 15 cents/kWh, indicated by positive average value of NPV (US$ 135,324,004) and the average value of both of IRRs are bigger than MARR (IRR project = 10.65 %, IRR Equity = 14.29 %, while MARR = 10 %). The probability of rejection of the SMR project was about 20 %. The three main variables that are most influential in the project were: selling price of electricity, investment cost and inflation rate. (author)

    Capability of various aeration techniques to remove radon from water in small waterworks was studied as a part of project (Treatment Techniques for Removing Natural Radionuclides from Drinking Water), which was carried out during 1997-1999 on a cost-shared basis (contract No. F14PCT960054) with The European Commission (CEC) under the supervision of the Directorate-General XII Radiation Protection Research Unit. In TENAWA project both laboratory and field experiments were performed in order to find reliable methods and equipment for removing natural radionuclides from ground water originating either from private wells or small waterworks. Because such techniques are more often needed in private households than at waterworks, the main emphasis of the research was aimed to solve the water treatment problems related to the private water supplies, especially bedrock wells. Radon was the most important radionuclide to be removed from water at waterworks whereas the removal of other radionuclides ( sup 2 sup 3 sup 4...

    We describe current pubertal development in healthy urban Chinese boys. A cross-sectional study of the pubertal development of 18,807 urban Chinese boys aged from 3.50 to 18.49years was conducted between 2003 and 2005. Testicular volume was evaluated with a Prader orchidometer. Pubic hair development was assessed according to the Tanner method. Data on spermarche were collected using the status quo method. Probit analysis was used to calculate the median age and 95% CI at different stages of testicular development, pubic hair development and spermarche. By age 9, 12.99% of the boys had a testicular volume of 4mL or greater. The median age of onset of puberty defined as the age at attainment of testicular volume of 4mL or greater was 10.55 (95% CI 10.27-10.79) years. The median age for onset of pubic hair development (PH(2) ) and spermarche was 12.78 (95%CI 12.67-12.89) years and 14.05 (95%CI 13.80-14.32) years, respectively. Pubertal onset in urban Chinese boys is earlier than currently used clinical norms but their pubic hair development occurs relatively late in comparison with the reported data from numerous other countries. There is also evidence of a secular trend towards an earlier age of spermarche since 1979 in Chinese urban boys. © 2011 The Authors.

    In a period of 6 years 144 asymptomatic boys with cryptorchidism, of mean age 7 ± SD 3.5 years, underwent orchiopexy. None of these boys referred to a history of a known urological anomaly, urinary tract infection haematuria, palpable mass in the renal region, bladder extrophy, epispadias, hypospadias or anorectal malformation. On the third day after orchiopexy an intravenous pyelography was done in every boy following testicular protection against irradiation. Ultrasonic investigation was not available at that time. There were minor urological abnormalities in 36 (25%) boys and major ones in 8 (5.5%) boys. A major anomaly is defined as one resulting in significant loss of renal substance (one case of single kidney and three cases of unilateral renal hypoplasia), or requiring surgical correction for conservation of the renal substance (one case of ureterocele, two cases of pelviureteric stenosis and one case of vesicoureteric stenosis with ipsilateral hydronephrosis). The unsuspected major urological abnormalities are usually ipsilateral to the more undescended testis. They may be associated with a hernia and are more frequent in bilateral cryptorchidism. In conclusion we encourage the routine use of IVP, or ultrasonic investigation or dynamic renal scanning (99 mTc -DTPA), if it is possible, in all patients undergoing orchiopexy for the detection of an unsuspected major renal anomaly.

    Full Text Available Introduction and Aim. Down syndrome (DS is associated with numerous developmental abnormalities, some of which cause dysfunctions of the posture and the locomotor system. The analysis of selected features of the foot structure in boys with DS versus their peers without developmental disorders is done. Materials and Methods. The podoscopic examination was performed on 30 boys with DS aged 14-15 years. A control group consisted of 30 age- and gender-matched peers without DS. Results. The feet of boys with DS are flatter compared to their healthy peers. The hallux valgus angle is not the most important feature differentiating the shape of the foot in the boys with DS and their healthy peers. In terms of the V toe setting, healthy boys had poorer results. Conclusions. Specialized therapeutic treatment in individuals with DS should involve exercises to increase the muscle strength around the foot joints, enhancing the stabilization in the joints and proprioception. Introducing orthotics and proper footwear is also important. It is also necessary to monitor the state of the foot in order to modify undertaken therapies.

    1999-01-01

    The NRSE trust fund established with financial support from the Italian Government has succeeded in catalyzing a number of energy projects in small island developing countries. These projects have elicited a great deal of interest by local communities and opened up prospects for further utilization of locally available energy resources. The projects have created a positive impact on the quality of life of people in dispersed locations in small island developing countries by focusing on provision of renewable energy based electricity services such as solar PV lighting for homes, schools, and hospitals; radio, TV, VCR as well as medicine refrigerators. Thus it has become evident that renewable energy technologies such as solar and wind systems can have an important role to play in improving the quality of life of people in these small island countries. Market potential for these technologies is indeed substantial. However constraints and barriers still exist. One of the principal barriers is still the high initial cost of solar devices. Innovative financing including microcredit facilities needs to be explored. Efforts are also needed to strengthen local capacity to undertake assembly of components and systems, and also in the installation, maintenance, and service of renewable energy devices. Entrepreneurial activities need to be fostered through further strengthening of skills in this area. (EHS)

    2012-11-01

    A new collection model was designed and tested in Catalonia (Spain) to foster the separate collection and recycling of electrical and electronic toys, with the participation of selected primary and secondary schools, as well as waste collection points and municipalities. This project approach is very original and important because small household WEEE has low rates of collection (16-21% WEEE within the EU or 5-7% WEEE in Spain) and no research on new approaches to enhance the collection of small WEEE is found in the literature. The project was successful in achieving enhanced toys collection and recycling rates, which went up from the national Spanish average of 0.5% toys before the project to 1.9 and 6% toys during the two project years, respectively. The environmental benefits of the campaign were calculated through a life-cycle approach, accounting for the avoided impact afforded by the reuse of the toys and the recycling of the valuable materials contained therein (such as metals, batteries and circuit boards) and subtracting the additional environmental burdens associated with the establishment of the collection campaign.

    Erhardt, Drew; Hinshaw, Stephen P

    1994-08-01

    This study systematically compared the influence of naturalistic social behaviors and nonbehavioral variables on the development of peer status in 49 previously unfamiliar boys, aged 6-12 years, who attended a summer research program. Twenty-five boys with attention-deficit hyperactivity disorder (ADHD) and 24 comparison boys participated. Physical attractiveness, motor competence, intelligence, and academic achievement constituted the nonbehavioral variables; social behaviors included noncompliance, aggression, prosocial actions, and isolation, measured by live observations of classroom and playground interactions. As early as the first day of interaction, ADHD and comparison boys displayed clear differences in social behaviors, and the ADHD youngsters were overwhelmingly rejected. Whereas prosocial behavior independently predicted friendship ratings during the first week, the magnitude of prediction was small. In contrast, the boys' aggression (or noncompliance) strongly predicted negative nominations, even with nonbehavioral factors, group status (ADHD versus comparison), and other social behaviors controlled statistically. Implications for understanding and remediating negative peer reputations are discussed.

    This paper presents an academic project that addresses the issue of international corruption in the engineering and construction industry, in a manner that effectively incorporates several learning experiences. The major objectives of the project are to provide the students a learning activity that will 1) make a meaningful contribution within the disciplines being studied; 2) teach by experience a significant principle that can be valuable in numerous situations during an individual's career, and 3) engage the minds, experiences, and enthusiasm of the participants in a real ethical challenge that is prevalent in all of their chosen professional fields. The paper describes the full details of the project, the actual implementation of it during Winter Semester 2005, the experiences gained during the initial trial, and the modifications and improvements incorporated for future implementation.

    1998-11-01

    To identify the family and child determinants of aggressive behaviour in Nigerian elementary school boys and to compare the findings with previous ones from Western studies. Forty-seven aggressive boys from four elementary schools in Lagos, Nigeria were compared with 47 matched pro-social boys. Teacher rating and peer nomination were combined to select subjects. The subjects and their parents were given structured questionnaires to obtain information on possible risk factors for aggression. Compared with pro-social boys, it was found that significantly more aggressive boys came from polygamous families and crowded homes, had more siblings, received less parental affection, were more physically punished, less supervised at home, witnessed more domestic conflicts, did poorly at school, had poorer verbal intelligence and attributed malice more readily than pro-social boys. Logistic regression indicated that the independent family predictors of aggression were crowding, little paternal affection, and corporal punishment. The independent child predictors were biased attribution and poor school achievement. Corporal punishment at school was also an independent predictor of aggression. The family and child determinants of aggressive behaviour in Nigeria are similar to those found in Western studies except for the small contribution of family instability and overwhelming influence of corporal punishment in our sample. Models of intervention developed in the West may therefore be cautiously applied to Nigerian children.

  20. Distribution and abundance of small plastic debris on beaches in the SE Pacific (Chile): a study supported by a citizen science project.

    The accumulation of large and small plastic debris is a problem throughout the world's oceans and coastlines. Abundances and types of small plastic debris have only been reported for some isolated beaches in the SE Pacific, but these data are insufficient to evaluate the situation in this region. The citizen science project "National Sampling of Small Plastic Debris" was supported by schoolchildren from all over Chile who documented the distribution and abundance of small plastic debris on Chilean beaches. Thirty-nine schools and nearly 1000 students from continental Chile and Easter Island participated in the activity. To validate the data obtained by the students, all samples were recounted in the laboratory. The results of the present study showed that the students were able to follow the instructions and generate reliable data. The average abundance obtained was 27 small plastic pieces per m(2) for the continental coast of Chile, but the samples from Easter Island had extraordinarily higher abundances (>800 items per m(2)). The abundance of small plastic debris on the continental coast could be associated with coastal urban centers and their economic activities. The high abundance found on Easter Island can be explained mainly by the transport of plastic debris via the surface currents in the South Pacific Subtropical Gyre, resulting in the accumulation of small plastic debris on the beaches of the island. This first report of the widespread distribution and abundance of small plastic debris on Chilean beaches underscores the need to extend plastic debris research to ecological aspects of the problem and to improve waste management.

    Cryptorchidism is an ubiquitous feature in prune belly syndrome (PBS). Laparoscopic orchidopexy allows dissection of the spermatic cord with minimal morbidity. We discuss the technical difficulties and outcome of three boys with PBS who underwent two-stage laparoscopic Fowler-Stephens orchidopexy (F-SO). Three boys, ages 1, 2, and 4, underwent laparoscopic F-SO. All boys had viable testes that were found within 3 cm of the deep inguinal ring. The testicular vessels were either ligated bilaterally with 4/0 polyglactin or monopolar diathermy was used and the vessels divided. Bilateral second-stage F-SO was performed within 6 months in two boys and limited to one side in the third boy. One boy awaits the contralateral second stage. All three boys have adequately sized gonads. Based on our experience, the port incisions should be smaller than routine practice to prevent air leak in PBS. Although the intra-abdominal pressure of 12 mm Hg did not vary from our normal practice, a high flow rate is necessary after initial insufflation (6 L/min) to compensate for inevitable gas leaks because the abdominal wall is so thin. Risk of diathermy injury to the thin abdominal wall and the vessels is significant. Laparoscopy enables easy visualization of the ureter, testes, and testicular vessels and permits complete dissection of testicular vessels. It is easier to maintain integrity of spermatic vessels. Use of radially expanding trocars, small incisions, and high gas flow rates permit this procedure to be performed safely with good outcome and cosmetic results in this challenging group of boys.

    Knowledge of all aspects of the hydrologic cycle is required for consideration of Yucca mountain as a high level radioactive waste site. Surface processes are especially important in controlling the quantity and quality of water infiltrating into the unsaturated zone, available for recharging the aquifer. The investigation reported herein uses small bore drill holes to access the near surface fractured rock environment. The study was conducted in northern Nevada at the north end of the Pah Rah range, east of Pyramid Lake as an analog to Yucca Mountain. The results of this study will be used to better understand the chemistry and flow of the near surface flow regime of Yucca Mountain and to evaluate proposed techniques for use in future investigations. 7 refs., 6 figs., 3 tabs

  6. Boys Are Victims, Too: The Influence of Perpetrators' Age and Gender in Sexual Coercion Against Boys.

    2018-06-01

    Sexual coercion among adolescent boys in South Africa is an underresearched topic despite the frequency of such events. Although quantitative research has illuminated the prevalence of sexual coercion toward boys, it has provided little understanding of the context of sexual coercion for adolescent boys. Given the often severe consequences of sexual coercion, it is important to further understand these experiences to inform prevention efforts. The current study aims to provide a more nuanced understanding of the context of sexual coercion. Data come from the baseline assessment for a translational research evaluation of a school-based intervention. The current study focuses on a subset of early and middle adolescent boys who reported experiencing sexual coercion ( n = 223). Analyses examine boys' reports of their perpetrators' characteristics and details about the sexual coercion encounter. Logistic regression is used to examine how coercion tactics used by the perpetrator differs depending on the perpetrator's age and gender. Eighth-grade boys were most likely to report that their perpetrator was a similar-aged female and that perpetrator's age played a particularly important role in what tactics were used. Adult perpetrators were more likely to use physical force, threaten them, harass them electronically, and drink or use drugs at the time. Results provide important insight into boys' experiences of sexual coercion that have implications for both future research and intervention efforts. Although much research is needed on the topic, intervention programs should recognize that both male and female adolescents can be victim and perpetrator.

    This report for the Swiss Federal Office of Energy (SFOE) reports on the preliminary project for a small hydropower plant in Chippis, Switzerland. The project takes advantage of an existing irrigation scheme that deviates water from the Navisence River into two successive tunnels (total 1.8 km) and a following channel built on steep mountain sides. The basic idea of the project is to increase the flow rate entering the tunnels from 265 l/s to 1265 l/s and to lead the additional 1000 l/s to a new penstock connected to the second tunnel's outlet. In this way, a hydraulic head of 130 m could be used for power generation for over 600 households (mechanical power: 0.8 to 1.1 MW, annual electrical energy production: 2.5 to 3.6 GWh, depending on the variant considered). The report reviews the history of water use at this location and its present use as well as a feasibility study previously made. The project is described, including water collection points, conduits, the power station and the particular aspects of the joint use of water for power generation and irrigation from mid April to mid September. Technical details on water quantities and energy production are presented. Financial aspects including construction and operating costs are presented and the economic viability of the project is discussed. Environmental aspects are reviewed. Further steps to be taken in the realisation of this hydropower installation are listed.

  16. Small power reactor projects in the United States of America and Canada. Information gathered as a result of invitations from Member States

    International Nuclear Information System (INIS)

    1962-01-01

    As part of its activities in connection with the development of nuclear power, and in response to the resolutions adopted by the General Conference, the Agency has been undertaking a continuing study of the technology and economics of small and medium sized power reactors, particularly with reference to the needs of the less-developed countries. This report summarizes the information gathered on the small power reactor projects in the United States of America and Canada, as a result of the opportunity afforded by these Member States to the Agency. It may be recalled that, at the third regular session of the General Conference, the United States Government offered to provide the Agency with relevant technical and economic data on several small power reactor projects of its Atomic Energy Commission. The Agency accepted the offer and since June 1960 it has sent one or two staff members at approximately six-monthly intervals to follow the development of nine power reactor projects in the United States which represent six different reactor systems. Last year, the Agency issued a report summarizing the information obtained through their visits and study of available published literature. The present document, which should be read in conjunction with that document, brings the information up to date and provides additional information on certain phases of the projects already discussed in the last report. Three more power reactor projects are also dealt with, namely the experimental gas-cooled reactor (EGCR), the high temperature gas-cooled reactor (HTGR) and the Hallam nuclear power facility (HNPF). Early in 1962, the Canadian Government expressed its willingness to make available to the Agency relevant information on the NPD and CANDU projects. The coverage of the NPD reactor is based upon the published information supplied by AECL of Canada and the visit by one of the staff members to the NPD site. The Agency wishes to acknowledge with thanks the co-operation extended

    Software is becoming increasingly significant in today's critical avionics systems. To achieve safe, reliable software, government regulatory agencies such as the Federal Aviation Administration (FAA) and the Department of Defense mandate the use of certain software development methods. However, little scientific evidence exists to show a correlation between software development methods and product quality. Given this lack of evidence, a series of experiments has been conducted to understand why and how software fails. The Guidance and Control Software (GCS) project is the latest in this series. The GCS project is a case study of the Requirements and Technical Concepts for Aviation RTCA/DO-178B guidelines, Software Considerations in Airborne Systems and Equipment Certification. All civil transport airframe and equipment vendors are expected to comply with these guidelines in building systems to be certified by the FAA for use in commercial aircraft. For the case study, two implementations of a guidance and control application were developed to comply with the DO-178B guidelines for Level A (critical) software. The development included the requirements, design, coding, verification, configuration management, and quality assurance processes. This paper discusses the details of the GCS project and presents the results of the case study.

    The goal in the small-scale production of wood fuels in the context of the Bioenergy research programme is to reduce production costs by 20 % when compared to the 1992 cost level. Also, new harvesting technology and new work methods will be developed for forest owners and small-entrepreneurs in the course of the research programme. The goal of the research work will be to improve the competitiveness of harvesting machines, devices and work chains when dealing with small-diameter trees and logging residues. The aim in the development of measuring methods and quality requirements for purchased fuelwood is to eliminate obstacles resulting from the ambiguities in the measuring and quality of fuelwood. The objective of the fuelwood utilisation research is to eliminate technical obstacles and to develop new action models for organising energy generation in the categories of building-specific and district heating. Also, marketing of the new action models to potential entrepreneurs and heating energy purchasers is an important part of the work. The main objective of the work on the development of fireplaces is to reduce fluegas emissions. The main subject of development of heating equipment designed for buildings is stoker burners for wet fuels (orig.)

    Context Multiple studies have reported an overgrowth in head circumference (HC) in the first year of life in autism. However, it is unclear whether this phenomenon is independent of overall body growth and whether it is associated with specific social or cognitive features. Objectives To examine the trajectory of early HC growth in autism compared with control groups; to assess whether HC growth in autism is independent of height and weight growth during infancy; and to examine HC growth from birth to 24 months in relationship to social, verbal, cognitive, and adaptive functioning levels. Design Retrospective study. Setting A specialized university-based clinic. Participants Boys diagnosed as having autistic disorder (n=64), pervasive developmental disorder–not otherwise specified (n=34), global developmental delay (n=13), and other developmental problems (n=18) and typically developing boys (n=55). Main Outcome Measures Age-related changes in HC, height, and weight between birth and age 24 months; measures of social, verbal, and cognitive functioning at age 2 years. Results Compared with typically developing controls, boys with autism were significantly longer by age 4.8 months, had a larger HC by age 9.5 months, and weighed more by age 11.4 months (P=.05 for all). None of the other clinical groups showed a similar overgrowth pattern. Boys with autism who were in the top 10% of overall physical size in infancy exhibited greater severity of social deficits (P=.009) and lower adaptive functioning (P=.03). Conclusions Boys with autism experienced accelerated HC growth in the first year of life. However, this phenomenon reflected a generalized process affecting other morphologic features, including height and weight. The study highlights the importance of studying factors that influence not only neuronal development but also skeletal growth in autism. PMID:21969460

    Full Text Available Background: Some boys with sexual precocity are known to have behavioral problems like increased physical and verbal aggression and school and social maladjustments. It is believed to be due to premature androgen exposure. However, it is not clear why only some develop this problem, difference in etiology could be one explanation. Aim: The aim of the study is to assess behavioral aggression in boys with sexual precocity due to different disorders. Materials and Methods: Seven children, ages three to seven years, were enrolled for this study. Two were diagnosed to have congenital adrenal hyperplasia (CAH, three had testotoxicosis, while two had central precocious puberty. Parents of children with precocious puberty underwent the (CASP questionnaire (children′s aggression scale-parent version. Results: Testosterone levels were high in all patients. Parents denied any history of physical or verbal aggression in the two boys with CAH. Their CASP rating was 0. In contrast, the CASP ratings in the two boys with testotoxicosis and the two with precocious puberty for five domains ranged from 3.1 - 24.2, 2.6 - 8.3,1-5.6,0 - 7.1, and 0 - 1, respectively. In the present study, increased aggression was seen among all the patients with testotoxicosis and both with precocious puberty. In contrast, there were no symptoms of either increased verbal or physical aggression in either of the two patients with CAH. Conclusions: The hormonal milieu in the boys with CAH versus those with sexual precocity due to other causes differed in terms of cortisol and androgen precursors. The androgen excess in CAH children was a consequence of cortisol deficiency. It is possible that cortisol sufficiency is required for androgen-mediated behavioral effects.

    . The effects were associated with the maternal exposure levels, so that high-exposed boys had smaller genitals than medium-exposed boys, who had smaller genitals than those who were unexposed. Boys of mothers in the high exposure group (n = 23) had 24.7% smaller testes (95% CI: -62.2; -10.1) and 9.4% shorter...... penile length (95% CI: -16.8; -1.1) compared with the unexposed. The testicular volume and penile length at school age could be tracked to measures from the same boys made at 3 months, e.g. those that had small testes at school age also had small testes at 3 months.

    The aim of this study was to explore the effect of the Active Teen Leaders Avoiding Screen-time (ATLAS) intervention on psychological well-being in adolescent boys and to examine the potential mediating mechanisms that might explain this effect. ATLAS was evaluated using a cluster randomized controlled trial in 14 secondary schools located in low-income communities (N = 361 adolescent boys, mean age = 12.7 ± .5 years). The 20-week intervention was guided by self-determination theory and involved: professional development for teachers, provision of fitness equipment to schools, enhanced school sport sessions, researcher-led seminars, a smartphone application, and parental strategies for reducing screen time. Assessments were conducted at baseline and immediately post intervention (8 months). Psychological well-being was measured using the Flourishing Scale. Motivational regulations (intrinsic, identified, introjected, controlled, and amotivation) and basic psychological needs (autonomy, competence, and relatedness) in school sport, muscular fitness, resistance training skill competency, and recreational screen time were examined as potential mediating mechanisms of the intervention effect. The intervention effect on well-being was small but statistically significant. Within a multiple mediator model, changes in autonomy needs satisfaction, recreational screen time, and muscular fitness significantly mediated the effect of the intervention on psychological well-being. In addition to the physical health benefits, targeted physical activity programs for adolescent boys may have utility for mental health promotion through the mechanisms of increasing autonomy support and muscular fitness and reducing screen time.

  6. Boy-lovers and their influence on boys: distorted research and anecdotal observations.

    Brongersma, E

    1990-01-01

    A wide experience with boy-lovers has convinced the author that one can often learn more about them from reading some excellent novels than from so-called scientific studies. All too often research is unreliable because (1) it assumes pedosexual activity is a positive indicator of pedophilia; (2) no distinction is drawn between pseudo-pedophiles and real pedophiles; (3) no difference is recognized between boys and girls as partners; and (4) it is highly distorted by bias. Representative samples for research cannot be drawn from members of boy-love organizations. The incidence of violence is very low in pedophile contacts with boys. The influence can be strong in lasting relationships; it can be either wholesome or unwholesome. Within a relationship, sex is usually only a secondary element, although it can be important in sexual instruction and education. The impact of the law, the hostility of parents and the problem of the partners' inequality are discussed.

    The purpose of the study was (1) to investigate gender role behaviors of boys with hypospadias compared with groups of unaffected boys and girls using parental reports and direct observations; and (2) to directly observe effects of socialization (mothers' presence) on children's gender role behaviors. Ages of 19 children with hypospadias ranged from 3 to 7 years, and each of them were matched to controls of unaffected boys and girls by age. All the children participated with their mothers. Children's gender role behaviors and their mothers' behaviors were evaluated using an observation coding system. Mothers also completed questionnaires regarding their children's gender role behaviors. Results indicated no atypical gender role behavior for the boys with hypospadias and no direct effects of socialization on their gender role behaviors. However, differences were found in negative communicative behaviors between boys with hypospadias and unaffected boys, suggesting a possible role of socialization. © The Author 2014.

  10. Update on CNSC's readiness to regulate projects proposing the use of Small Modular Reactors (SMR)

    International Nuclear Information System (INIS)

    De Vos, M.; Lee, K.

    2014-01-01

    Over the past few years, Canadian Nuclear Security Commission (CNSC)staff have been working to identify and understand key regulatory and technical issues that may be encountered in Small Modular Reactor (SMR) deployment scenarios in Canada. This work is considered necessary not only to be ready to engage with vendors and utilities in technical and licensing discussions, but also to prepare to disseminate objective scientific, technical and regulatory information to the public. Beyond size differences, SMRs are reactor-based facilities. The main finding from CNSC's work-to-date is that most, if not all, of the regulatory issues to be addressed from a Canadian perspective are due to the alternate or novel approaches that proponents of SMRs are proposing and that present uncertainties from the perspective of proven technology or public acceptance. These uncertainties represent risks that need to be mitigated by proponents before the environmental assessment and licensing processes are initiated. Examples of alternate or novel approaches include, but are not limited to: non-traditional siting scenarios (remote regions, near industrial facilities, in urban areas); increased use of physical design measures to reduce the need for security personnel; fleet-based regional emergency planning and response; design specific passive design features; and, remote operation of the facility This paper covers two main themes: 1. CNSC staff have made significant progress in the ongoing characterization of key regulatory and licensing issues that may emerge in deployment of both large and / or small SMRs in Canada. This work informs CNSC’s regulatory framework activities. 2. Many regulatory framework development activities (e.g. REGDOCs) have either already accounted for SMR concepts in the development of requirements and guidance or are planning to do so. This includes taking into account the ability to use a graded approach. (author)

  11. Atomistic modelling of scattering data in the Collaborative Computational Project for Small Angle Scattering (CCP-SAS).

    The capabilities of current computer simulations provide a unique opportunity to model small-angle scattering (SAS) data at the atomistic level, and to include other structural constraints ranging from molecular and atomistic energetics to crystallography, electron microscopy and NMR. This extends the capabilities of solution scattering and provides deeper insights into the physics and chemistry of the systems studied. Realizing this potential, however, requires integrating the experimental data with a new generation of modelling software. To achieve this, the CCP-SAS collaboration (http://www.ccpsas.org/) is developing open-source, high-throughput and user-friendly software for the atomistic and coarse-grained molecular modelling of scattering data. Robust state-of-the-art molecular simulation engines and molecular dynamics and Monte Carlo force fields provide constraints to the solution structure inferred from the small-angle scattering data, which incorporates the known physical chemistry of the system. The implementation of this software suite involves a tiered approach in which GenApp provides the deployment infrastructure for running applications on both standard and high-performance computing hardware, and SASSIE provides a workflow framework into which modules can be plugged to prepare structures, carry out simulations, calculate theoretical scattering data and compare results with experimental data. GenApp produces the accessible web-based front end termed SASSIE-web , and GenApp and SASSIE also make community SAS codes available. Applications are illustrated by case studies: (i) inter-domain flexibility in two- to six-domain proteins as exemplified by HIV-1 Gag, MASP and ubiquitin; (ii) the hinge conformation in human IgG2 and IgA1 antibodies; (iii) the complex formed between a hexameric protein Hfq and mRNA; and (iv) synthetic 'bottlebrush' polymers.

  13. Small Reactors without On-site Refuelling: Neutronic Characteristics, Emergency Planning and Development Scenarios. Final Report of an IAEA Coordinated Research Project

    International Nuclear Information System (INIS)

    2010-09-01

    Small reactors without on-site refuelling have a capability to operate without reloading or shuffling of fuel in their cores for reasonably long periods of time consistent with plant economy and considerations of energy security, with no fresh or spent fuel being stored at the site during reactor operation. In 2009, more than 25 design concepts of such reactors were analyzed or developed in IAEA Member States, representing both developed and developing countries. Small reactors without on-site refuelling are being developed for several reactor lines, including water cooled reactors, sodium cooled fast reactors, lead and lead bismuth cooled reactors, and also include some non-conventional concepts. Most of the concepts of small reactors without on-site refuelling reactors are at early design stages. To make such reactors viable, further research and development (R and D) is necessary, inter alia, to validate long-life core operation, define and validate new robust types of fuel, justify an option of plant location in the proximity to its users, and examine possible niches that such reactors could fill in future energy systems. To further research and development (R and D) in the areas mentioned above and several others, and to facilitate progress in Member States in design and technology development for small reactors without on-site refueling, the IAEA has conducted a dedicated Coordinated Research Project (CRP) entitled 'Small Reactors without On-site Refuelling' (CRPi25001). The project started late in 2004 and, after a review in 2008, was extended for one more year to be ended in 2009. The project has created a network of 18 research institutions from 10 Member States, representing both developed and developing countries. Over the CRP period, collaborative results were achieved for many of the abovementioned research areas. Some studies highlighted new directions of research to be furthered after the CRP completion. Some studies remained the efforts of

    This report for the Swiss Federal Office of Energy (SFOE) takes a look at a project for the realisation of a small hydro-power plant in the municipality of Anzonico, southern Switzerland. The water of a small alpine stream is to be used for power generation and vineyard irrigation as well as for the creation of an additional water resource for fire fighting in this sensitive region. The report is foreseen to support the request for a water usage concession to the authorities of the Canton of Ticino. It presents details on the hydrological data for the river and the dimensioning of the installation. The hydrological installations and the turbine foreseen are described and discussed, as is the removal of river sediment. The electricity production expected is discussed, as is the economic viability of the project. Synergies exist with the local electricity utility that will renew and improve its power distribution and telecommunication system when the penstock will be mounted in the underground.

    Climate change and the needed reductions in the use of fossil fuels call for the development of renewable energy sources. However, renewable energy production, such as hydropower (both small- and large-scale) and wind power have adverse impacts on the local environment by causing reductions in biodiversity and loss of habitats and species. This paper compares the environmental impacts of many small-scale hydropower plants with a few large-scale hydropower projects and one wind power farm, based on the same set of environmental parameters; land occupation, reduction in wilderness areas (INON), visibility and impacts on red-listed species. Our basis for comparison was similar energy volumes produced, without considering the quality of the energy services provided. The results show that small-scale hydropower performs less favourably in all parameters except land occupation. The land occupation of large hydropower and wind power is in the range of 45-50 m(2)/MWh, which is more than two times larger than the small-scale hydropower, where the large land occupation for large hydropower is explained by the extent of the reservoirs. On all the three other parameters small-scale hydropower performs more than two times worse than both large hydropower and wind power. Wind power compares similarly to large-scale hydropower regarding land occupation, much better on the reduction in INON areas, and in the same range regarding red-listed species. Our results demonstrate that the selected four parameters provide a basis for further development of a fair and consistent comparison of impacts between the analysed renewable technologies.

    Longitudinal studies found that criminal behavior in juveniles often concurs with neighborhood disadvantage and family dysfunction, especially in girls. In this study we assessed the psychosocial background in incarcerated juveniles and analyzed the data for each gender separately. The Multidimensional Clinical Screening Inventory for delinquent juveniles (MCSI) was used to assess school history, psychiatric history, family background, abuse and neglect and motive for crime. The sample consisted of 294 juveniles (46 females and 248 males). Innerfamilial abuse/neglect was reported by 91% (girls) and 79% (boys). 76% (girls) and 88% (boys) reported school-problems. 57% (girls) and 29% (boys) reported to have recieved psychiatric pretreatment. In girls we found significantly higher prevalence rates for parental divorce, incarceration of mother, abuse/neglect and psychiatric pretreatment. Significantly more girls reported a co-occurrence of school-problems and experiences of separation and loss and abuse (65.2% vs. 46.4%, χ²=5.51, df=1, p<.05). Incarcerated juveniles, especially females, are and have been exposed to multiple psychosocial burdens. Therefore it is necessary to implement prevention programs for psychosocially stressed families. Forensic intervention in and after detention has to include a family centered approach.

  17. Boys in India challenge gender stereotypes.

    Science.gov (United States)

    1998-01-01

    This article discusses CEDPA's Better Life Options Program in India. The program was initiated in 1987 to challenge gender inequities. The program offers over 400,000 girls a chance to develop skills and self-confidence for increasing their options in education, social mobility, work, health, and family and community roles. CEDPA's partner, Prerana, offers an integrated program that provides literacy training, vocational skills, after-school tutoring, health education, and family life education for about 600 girls/year. Vocational training includes nontraditional skills, such as video production and electronics. Prerana established a parallel program in 1994 for boys and young men that aims to change attitudes about girls and women and traditional gender roles. The program offers vocational skills, such as cooking and candle-making. Family life education teaches gender awareness and provides counseling and services for reproductive health. The Prerana program emphasizes men's shared responsibility in parenthood and sexual behavior, shared contribution to family income, health and nutrition, and prevention of violence against women. Since 1994, the program has included 1200 boys in 6 villages in New Delhi. Boys' enrollment is increasing; several young men have volunteered to become depot holders of contraceptive supplies in their villages. For example, one young man who was part of the Prerana program went on to be a depot holder and then a family planning promoter and counselor. He interacts with both young and older men. His contributions were well received by his village.

    This study examined the psychosocial and behavioral concomitants of anxiety in clinic-referred boys with attention-deficit/hyperactivity disorder (ADHD) with and without chronic multiple tic disorder (CMTD). ADHD boys with (n = 65) and without (n = 94) CMTD were evaluated with measures of psychiatric symptoms, mental health risk factors, and academic and social performance. Boys with CMTD evidenced more severe anxiety and less social competence and were more likely to be living with only one biological parent than the ADHD Only group, but the magnitude of group differences was generally small. The severity of generalized anxiety, separation anxiety, social phobia, and obsessive-compulsive symptoms were uniquely associated with a different pattern of risk factors, and there was some evidence that these patterns differed for the two groups of boys. Boys with CMTD had a relatively more severe and complex pattern of anxiety that was associated with different clinical features, all of which suggests that ADHD plus CMTD might better be conceptualized as a distinct clinical entity from ADHD Only. However, findings from the extant literature are mixed, and therefore this remains a topic for further study.

    Mechanical precision is a key-aspect of the high-rate capable Micromegas detectors for the upgrade of the Small Wheels of the ATLAS muon spectrometer. 32 SM2 quadruplets will be built by four German institutes with cathodes and strip-anodes made of stable honeycomb sandwiches. To achieve a single plane resolution below $100\\mu m$ the deviation from planarity of a single detector plane must not exceed $80\\mu m$ over the whole active area and the global position of the readout strips has to be within $30\\mu m$ for a single readout-plane of 3 PCB's, as well as between all four planes of a quadruplet. Precision tooling is used for the correct positioning of readout PCB's and readout sandwich planes. For quality control of the planarity of the sandwich planes a laser distance sensor combined with a coordinate measurement system has been developed. Deviation from planarity below 10 $\\mu$m can be easily resolved. We will present key features of the challenging construction procedure to achieve this high level of pre...

    2007-09-01

    This illustrated final report for the Swiss Federal Office of Energy (SFOE) is a feasibility study for the retrofitting of the small hydro electric scheme 'Moulin d'en Bas' located in Cronay on the Mentue river, Switzerland. Two variants are considered. In the first one the existing scheme uses a 4.72 m water fall and its power amounts to about 25 kW. A 4-blades Kaplan turbine is foreseen to generate 160,000 kWh/y. In the second variant, weir and penstock have to be adapted in order to take advantage of the full 6.74 m water fall indicated in the water-use concession granted in 1952. A new fish pass has to be built as well. The resulting electric power is in this case 80 kW and the power generation by the turbo group 353,000 kWh/y, about 60% of which in the wintertime. Electricity production cost is estimated to be 0.282 CHF/kWh in the second variant.

    In the future natural gas can be substituted by hydrogen. In the short term hydrogen can be produced from fossil fuels. Released CO 2 can be stored. In the long run it will be possible to produce hydrogen from renewable energy sources (solar cells and wind turbines), which can be transported to the consumer. In the study on the title subject attention is paid to different methods of hydrogen production from natural gas and from residual oils, costs and problems of hydrogen distribution, hydrogen appliances, and CO 2 storage. From the results it appears that a demonstration project to use hydrogen on a small-scale is feasible, although expensive. The costs of the reconstruction of the present natural gas distribution system to a hydrogen distribution system is higher than expected. The price of hydrogen per GJ is higher than the equal energy content of natural gas, in spite of a reduction of the energy levy. The demonstration project will be 25% cheaper per GJ hydrogen when carried out in a newly built area. A demonstration project in which hydrogen is mixed with natural gas is even a factor 2 cheaper. 17 refs., 7 appendices

    Conclusions: • From the standpoint of population, the opportunity of catastrophic consequences caused by nuclear accident is much more important than very low possibility of its realization. • The level of social acceptability of future large-scale NP must be higher. • Use of the nuclear power technology (NPT) based on RFs, in which the value of stored potential energy of different kinds is minimal, will meet that goal the most efficient. • Those RFs cannot amplify the external impacts, therefore, the scale of damages will be only determined by the external impact energy, the exhaust of radioactivity being localized. • Now there are no developed NPTs with such properties. • The NPT based on modular fast reactors SVBR-100 and verified in conditions of NS operating is to the most extent ready to be demonstrated. • Federal target program “New Generation Nuclear Power Technologies for 2010 – 2015 Years and Future Trends up to 2020” stipulates the construction of experimental-industrial power-unit SVBR-100. • The project is realized within the frameworks of state-private partnership by joint venture JSC “AKME-Engineering” organized on a parity basis by State Atomic Energy Corporation “Rosatom” and Limited Liability Company “Irkutskenergo”. • The first of a kind power unit with RF SVBR-100 will be commissioned in 2017 near the SSC NIIAR site in Dimitrovgrad (Ulyanovsk region). • Widespread common use of this NPT, which potentials are very high, is expected to begin in ∼ 2020 – 2025. In case of earlier starting, the economic risk will be high; in case it is launched later, much profit will be lost

    As a result of the joint work performed recently by FSUE OKB Gidropress, SNC RF-IPPE and other organizations the technical feasibility is shown for creation and usage in nuclear power engineering of the unified reactor plant (RP) SVBR-75/100 with fast neutron reactor core and lead-bismuth coolant (LBC) in the primary circuit. Technical design of SVBR-75/100 reactor plant is based on the following: 50-year operation experience in development and operation of RP with LBC for nuclear submarines; experience in development and operation of fast reactor with sodium coolant; experience in optimization of LBC technology at nuclear submarines and ground-based test benches; conceptual design of SVBR-75 reactor plant (for renovation of Units 2, 3 and 4 of Novovoronezh NPP). Technical solutions laid down in the basis of SVBR-75/100 reactor plant design are oriented towards the industrial basis, structural materials existing in Russia, as well as the unique LBC technology with experimental and practical support. The concept of SVBR-75/100 reactor plant safety assurance is based on the following provisions: maximum usage of inherent safety supported by physical features of fast neutron reactor, chemically inert LBC in the primary circuit, integral layout and special design solutions; maximum possible combination of normal operation and safety functions in RP systems. Small power of SVBR-75/100 RP makes it possible to manufacture the complete set of RP main equipment at the factory and delivery it to NPP site as-finished practically using any transport including railway. Possible fields of application of SVBR-75/100 reactor plants: modular NPPs of different power; renovation of NPPs with light water reactors exhausted their service life; independent nuclear power sources for different applications (ground-based nuclear water-desalinating plants, etc. )(author)

    A small hydro plant in Canada is defined as any project between 1 MW and 15 MW but the international standard is 10 MW. The global market for small hydro development was considered good. There are some 1000 to 2000 MW of generating capacity being added each year. In Canada, growth potential is considered small, primarily in remote areas, but significant growth is anticipated in Eastern Europe, Africa and Asia. Canada with its expertise in engineering, manufacturing and development is considered to have a good chance to take advantage of these growing markets

    The generation capacity of small-scale (less than one megawatt) fossil-fueled electricity in the United States is anticipated to grow by threefold to twenty-fold from 2015 to 2040. However, in adherence with internationally agreed upon carbon accounting methods, the Environmental Protection Agency's (EPA's) U.S. Greenhouse Inventory (GHGI) does not currently attribute greenhouse gases (GHGs) from these small-scale distributed generation sources to the electric power sector and instead accounts for these emissions in the sector that uses the distributed generation (e.g., the commercial sector). In addition, no other federal electric-sector GHG emission data product produced by the EPA or the U.S. Energy Information Administration (EIA) can attribute these emissions to electricity. We reviewed the technical documentation for eight federal electric-sector GHG emission data products, interviewed the data product owners, collected their GHG emission estimates, and analyzed projections for growth in fossil-fueled distributed generation. We show that, by 2040, these small-scale generators could account for at least about 1%- 5% of total CO2 emissions from the U.S. electric power sector. If these emissions fall outside the electric power sector, the United States may not be able to completely and accurately track changes in electricity-related CO2 emissions, which could impact how the country sets GHG reduction targets and allocates mitigation resources. Because small-scale, fossil-fueled distributed generation is expected to grow in other countries as well, the results of this work also have implications for global carbon accounting.

    As adolescence is a critical period of development, and as boys are less inclined than girls to approach the school facility for adolescent counselling, segregated consulting hours were introduced for boys to attract those with problems. The frequency of consultations by boys increased by 25 per cent, and 70 per cent of the boys reported a preference for the segregated consulting hours; 75 per cent appreciated the absence of girls from the waiting room; and of the 42 per cent with special preferences regarding the gender of the staff encountered, half reported preferring a man. Most of the boys presented with defined problems, though many revealed other problems, often relating to sexuality, in the course of consultation. The availability of segregated consulting hours for boys with adolescent problems is important, and often the only way to reach young boys who need help.

    There is vigorous debate regarding the possibility that ADHD is overdiagnosed in boys. We investigated the impact of the gender stereotype depicting boys as inattentive and impulsive on neuropsychological assessment (observation of psychology students and child's cognitive performance). In experiment 1, after the stereotype was activated, psychology students rated a "boy," a "girl," or a "child" on a behavioral assessment scale. In experiment 2, 103 children (boys and girls) completed neuropsychological tasks under stereotype threat or neutral conditions. The gender stereotype led psychology students to assess a child's behaviors more negatively if they thought the child was a boy. Boys' performance on one cognitive score declined following stereotype threat. Regression path analyses suggested moderation by stigma consciousness. Additionally, there were mediating and suppressing (through stereotype endorsement) effects. Our results suggest that the gender stereotype might contribute to the overdiagnosis of ADHD in boys.

    In the food industry, injuries due to food poisoning have been increasing. Especially the mass outbreak of food poisoning by Escherichia coli such as O-157 in 1996 gave warning on the importance of food sanitation management. Public efforts such as the Hazard Analysis and Critical Control Point (HACCP) system have been made to prevent food poisoning. Recently, disinfection made by electrolyzing water with some salt added has attracted attention. Fuji Electric has developed the generator 'SaniBoy' that produces weak alkaline electrolyzed water without wasting water. The environment-friendly 'SaniBoy' will contribute to sanitation in various fields. (author)

    Since 1971 the Study of Mathematically Precocious Youth (SMPY) at Johns Hopkins University has pioneered in discovery of and provision of educational help for 12-year-old boys and girls who reason better mathematically than 99% of other 12-year-olds. SMPY originated widespread searches for such youths and special academic classes for them outside the regular school system. A regional talent search, verbal as well as mathematical, now covers all 50 states of the USA, and many varied residential summer programmes are offered across the country. These have provided educational facilitation for many thousands, and have encouraged greater curricular flexibility in schools and better articulation of in-school with out-of-school learning experiences. From the first talent search conducted by SMPY in 1972, it became obvious that boys tend to score considerably higher than girls on the College Board Scholastic Aptitude Test-Mathematical (SAT-M), a test intended mainly for college-bound 17- and 18-year-olds. This difference was reported in 1974 but attracted little attention until a controversial report in 1980 stimulated research on sex differences in various aspects of mathematics. Here I describe a study of sex differences over 10 years on 14 College Board high school achievement tests, which are taken (three usually) by bright 17- and 18-year-olds seeking admission to the USA's selective colleges and universities. Among the high scores on the European history test the ratio of males to females was greatest, 6:1. The next most sex-differentiating test was physics, 2.9:1, followed by elementary-level mathematics (mainly algebra and geometry), 2.5:1. Other ratios favouring males were, in 1991, chemistry (2.4:1), American history (2.1:1), biology (1.8:1), precalculus mathematics (1.6:1), Latin (1.6:1), French (1.4:1), modern Hebrew (1.1:1) and German (1.02:1). Tests in which more females were high scorers were literature (1.26:1), English composition (1.05:1) and Spanish (1

    Hydrological processes in the humid tropics are poorly understood and an important topic when it comes to water management in the seasonal tropics. The Smithsonian Tropical Research Institute, Panama Canal Watershed Experiment, Agua Salud Project, seeks to understand these processes and quantify the long-term effects of different land cover and uses across the Panama Canal Watershed. One of the project’s main objectives is to understand how reforestation effects seasonal stream flows. To meet this objective, a baseline characterization of hydrology on the small catchment scale is being assessed across different land uses typical in rural Panama. The small experimental catchments are found within Panama’s protected Soberania National Park and the adjacent headwaters of the Agua Salud and Mendoza Rivers, all of which are part of the greater Panama Canal Watershed. The land uses being monitored include a variety of control catchments as well as treated pasture sites. The catchments used for this study include a mature old regrowth forest, a 50% deforested or mosaic regrowth site, an active pasture and a monoculture invasive grass site (saccharum spontaneum) as experimental controls and two treated catchments that were recently abandoned pastures converted to teak and native species timber plantations. Installed instrumentation includes a network of rain gauges, v-notched weirs, atmometers, an eddy covariance system and an assortment of meteorological and automated geochemical sampling systems. Spatial, rainfall, runoff and ET data across these six geologically and topographically similar catchments are available from 2009 and 2010. Classic water balance and paired catchment techniques were used to compare the catchments on an annual, seasonal, and event basis. This study sets the stage for hydrologic modeling and for better understanding the effects of vegetation and land-use history on rainfall-runoff processes for the Agua Salud Project and Panama Canal

    The IAEA actively promotes the development of controlled fusion as a source of energy. Through its coordinated research activities, the IAEA helps Member States to exchange and establish scientific and technical knowledge required for the design, construction and operation of a fusion reactor. Due to their compactness, flexibility and low operation costs, small fusion devices are a great resource for supporting and accelerating the development of mainstream fusion research on large fusion devices such as the International Thermonuclear Experimental Reactor. They play an important role in investigating the physics of controlled fusion, developing innovative technologies and diagnostics, testing new materials, training highly qualified personnel for larger fusion facilities, and supporting educational programmes for young scientists. This publication reports on the research work accomplished within the framework of the Coordinated Research Project (CRP) on Utilization of the Network of Small Magnetic Confinement Fusion Devices for Mainstream Fusion Research, organized and conducted by the IAEA in 2011–2016. The CRP has contributed to the coordination of a network of research institutions, thereby enhancing international collaboration through scientific visits, joint experiments and the exchange of information and equipment. A total of 16 institutions and 14 devices from 13 Member States participated in this CRP (Belgium, Bulgaria, Canada, China, Costa Rica, the Czech Republic, the Islamic Republic of Iran, Kazakhstan, Pakistan, Portugal, the Russian Federation, Ukraine and the United Kingdom).

    Capability of various aeration techniques to remove radon from water in small waterworks was studied as a part of project (Treatment Techniques for Removing Natural Radionuclides from Drinking Water), which was carried out during 1997-1999 on a cost-shared basis (contract No. F14PCT960054) with The European Commission (CEC) under the supervision of the Directorate-General XII Radiation Protection Research Unit. In TENAWA project both laboratory and field experiments were performed in order to find reliable methods and equipment for removing natural radionuclides from ground water originating either from private wells or small waterworks. Because such techniques are more often needed in private households than at waterworks, the main emphasis of the research was aimed to solve the water treatment problems related to the private water supplies, especially bedrock wells. Radon was the most important radionuclide to be removed from water at waterworks whereas the removal of other radionuclides ( 234,238 U, 226,228 Ra, 210 Pb and 210 Po) was oft required from radonrich bedrock waters. The currently available methods and equipment were mainly tested during the field and laboratory experiments but the project was also aimed to find new materials, absorbents and membranes applicable for radionuclide removal from various types of ground waters (e.g. soft, hard, acidic). Because iron, manganese or organic occur in waters with radionuclides, their simultaneous removal was also studied. The project was divided into 13 work packages. In this report the results of the work package 2.2 are described. Elevated levels of radon and other natural radionuclides in European ground waters have been observed mainly in wide areas of the crystalline Scandinavian bedrock, especially in the granite rock areas of Finland and Sweden but also in more limited crystalline rock areas of Central and Southern Europe, Ukraine and Scotland. The radon removal efficiencies of different aeration methods

    Background: Phthalates are used as plasticizers in soft polyvinyl chloride (PVC) and in a large number of consumer products. Because of reported health risks, diisononyl phthalate (DiNP) has been introduced as a replacement for di(2-ethylhexyl) phthalate (DEHP) in soft PVC. This raises concerns because animal data suggest that DiNP may have antiandrogenic properties similar to those of DEHP. The anogenital distance (AGD)—the distance from the anus to the genitals—has been used to assess reproductive toxicity. Objective: The objective of this study was to examine the associations between prenatal phthalate exposure and AGD in Swedish infants. Methods: AGD was measured in 196 boys at 21 months of age, and first-trimester urine was analyzed for 10 phthalate metabolites of DEP (diethyl phthalate), DBP (dibutyl phthalate), DEHP, BBzP (benzylbutyl phthalate), as well as DiNP and creatinine. Data on covariates were collected by questionnaires. Results: The most significant associations were found between the shorter of two AGD measures (anoscrotal distance; AGDas) and DiNP metabolites and strongest for oh-MMeOP [mono-(4-methyl-7-hydroxyloctyl) phthalate] and oxo-MMeOP [mono-(2-ethyl-5-oxohexyl) phthalate]. However, the AGDas reduction was small (4%) in relation to more than an interquartile range increase in DiNP exposure. Conclusions: These findings call into question the safety of substituting DiNP for DEHP in soft PVC, particularly because a shorter male AGD has been shown to relate to male genital birth defects in children and impaired reproductive function in adult males and the fact that human levels of DiNP are increasing globally.

    2008-12-01

    This study investigated geology knowledge acquisition by Boy Scouts through use of the Boy Scout Geology Merit Handbook. In this study, boys engaged in hands-on interactive learning following the requirements set forth in the Geology Merit Badge Handbook. The purposes of this study were to determine the amount of geology content knowledge engendered in adolescent males through the use of the Geology Merit Badge Handbook published by the Boy Scouts of America; to determine if single sex, activity oriented, free-choice learning programs can be effective in promoting knowledge development in young males; and to determine if boys participating in the Scouting program believed their participation helped them succeed in school. Members of a local Boy Scout Troop between the ages of 11 and 18 were invited to participate in a Geology Merit Badge program. Boys who did not already possess the badge were allowed to self-select participation. The boys' content knowledge of geology, rocks, and minerals was pre- and post-tested. Boys were interviewed about their school and Scouting experiences; whether they believed their Scouting experiences and work in Merit Badges contributed to their success in school. Contributing educational theories included single-sex education, informal education with free-choice learning, learning styles, hands-on activities, and the social cognitive theory concept of self-efficacy. Boys who completed this study seemed to possess a greater knowledge of geology than they obtained in school. If boys who complete the Boy Scout Geology Merit Badge receive additional geological training, their field experiences and knowledge acquired through this learning experience will be beneficial, and a basis for continued scaffolding of geologic knowledge.

    A review of studies which investigated drawings of the ideal man and the occupational aspirations of boys (ages 11-18 years) from several countries indicated that becoming a professional athlete was a popular but unrealistic aspiration for many adolescent boys. Boys who were athletes and nonathletes from diverse ethnic groups and nationalities dreamed of becoming professional athletes. In two additional studies in the United States of America, adolescents were asked why they thought boys most often selected professional athlete as a possible future occupation. Adolescents perceived professional athletes as rich, famous, and glorified. Enhancement of status and financial gain were ranked as more important than the desire to play sports.

    Although various theories describe mechanisms leading to differential parenting of boys and girls, there is no consensus about the extent to which parents do treat their sons and daughters differently. The last meta-analyses on the subject were conducted more than fifteen years ago, and changes in gender-specific child rearing in the past decade are quite plausible. In the current set of meta-analyses, based on 126 observational studies (15,034 families), we examined mothers’ and fathers’ differential use of autonomy-supportive and controlling strategies with boys and girls, and the role of moderators related to the decade in which the study was conducted, the observational context, and sample characteristics. Databases of Web of Science, ERIC, PsychInfo, Online Contents, Picarta, and Proquest were searched for studies examining differences in observed parental control of boys and girls between the ages of 0 and 18 years. Few differences were found in parents’ use of control with boys and girls. Parents were slightly more controlling with boys than with girls, but the effect size was negligible (d = 0.08). The effect was larger, but still small, in normative groups and in samples with younger children. No overall effect for gender-differentiated autonomy-supportive strategies was found (d = 0.03). A significant effect of time emerged: studies published in the 1970s and 1980s reported more autonomy-supportive strategies with boys than toward girls, but from 1990 onwards parents showed somewhat more autonomy-supportive strategies with girls than toward boys. Taking into account parents’ gender stereotypes might uncover subgroups of families where gender-differentiated control is salient, but based on our systematic review of the currently available large data base we conclude that in general the differences between parenting of boys versus girls are minimal.

  14. South Africa's nuclear model: A small and innovative reactor is seen as the model for new electricity plants. The project is nearing the starting blocks

    2004-01-01

    Although nuclear power generation has by far the best safety and environmental record of any technology in general use, it has for many years been unable to make any meaningful inroads into the wall of negative perceptions that have arisen against it. But sentiments are changing rapidly on a global scale. The flare-up of oil prices is a sobering reminder of the volatility in the energy market, the exhaustibility of fossil fuels and the urgent need for stable, reliable, non-polluting sources of electrical power that are indispensable to a modern industrial economy. Today, new types of nuclear plants are prized, and South Africa is moving ahead. The State energy provider, Eskom, is internationally regarded as the leader in the field of the Pebble Bed Modular Reactor (PBMR) technology, a 'new generation' nuclear power plant. A decision on the PBMR project's future is on the near horizon. Should approvals be received in the coming months to proceed to the project's next phase, construction of the PBMR demonstration plant will start in 2006, in which case the reactor will start in 2010 and handed over to the client, Eskom, in 2011. Eskom has conditionally undertaken to purchase the first commercial units. Pebble bed reactors are small, about one-sixth the size of most current nuclear plants. Multiple PBMRs can share a common control center and occupy an area of no more than three football fields. More specifically, the PBMR is a helium-cooled, graphite moderated high temperature reactor (HTR). The concept is based on experience in the UK, United States and particularly Germany where prototype reactors were operated successfully between the late 1960s and 1980s. Although it is not the only high-temperature, gas-cooled nuclear reactor being developed in the world, the South African project is internationally regarded as a front-runner. The South African PBMR includes unique and patented technological innovations which make it particularly competitive. The Chief Executive

    African American (AA) boys face serious barriers to academic success, many of which are uncommon--or absent--in the lives of AA girls, other children of color, and European American children. In this chapter, we identify nine critical challenges to the successful education of AA boys and review possible solutions. In addition, we evaluate one particular reform, public single-sex schooling, as a possible solution to the challenges facing AA boys. Considering the evidence, we argue that recent efforts to expand the existence of public single-sex schools are rarely grounded in empirical findings. Given the lack of compelling evidence and the high stakes for AA boys, we call for more rigorous evaluations of the outcomes of sex-segregated programs that specifically target AA boys.

    Studies of the relationship of weight status with timing of puberty in boys have been mixed. This study examined whether overweight and obesity are associated with differences in the timing of puberty in US boys. We reanalyzed recent community-based pubertal data from the American Academy of Pediatrics' Pediatric Research in Office Settings study in which trained clinicians assessed boys 6 to 16 years for height, weight, Tanner stages, testicular volume (TV), and other pubertal variables. We classified children based on BMI as normal weight, overweight, or obese and compared median age at a given Tanner stage or greater by weight class using probit and ordinal probit models and a Bayesian approach. Half of boys (49.9%, n = 1931) were white, 25.8% (n = 1000) were African American, and 24.3% (n = 941) were Hispanic. For genital development in white and African American boys across a variety of Tanner stages, we found earlier puberty in overweight compared with normal weight boys, and later puberty in obese compared with overweight, but no significant differences for Hispanics. For TV (≥3 mL or ≥4 mL), our findings support earlier puberty for overweight compared with normal weight white boys. In a large, racially diverse, community-based sample of US boys, we found evidence of earlier puberty for overweight compared with normal or obese, and later puberty for obese boys compared with normal and overweight boys. Additional studies are needed to understand the possible relationships among race/ethnicity, gender, BMI, and the timing of pubertal development.

  10. A Boy with a Large Bladder Stone

    Kuo-Shen Chow

    2008-08-01

    Full Text Available Despite the frequent association of urinary tract infection with vesicoureteral reflux and urinary calculi, since vesicouretal reflux is induced by bladder stones, the coexistence of vesicoureteral reflux and bladder stones is rare. Because of its occurrence in children belonging to poor socioeconomic groups, it is believed to be a deficiency disorder. Most cases of bladder stones occur between the ages of 2 and 5 years. Common clinical presentations of bladder stones include urinary dribbling and enuresis, frequency of micturition, pain during micturition, pelvic pain and hematuria. We report the occurrence of a large bladder stone in a boy, who experienced intermittent lower abdominal pain and urinary incontinence, both during the day and at night. He had been diagnosed with enuresis and treated in pediatric clinics for 1 year. Delayed diagnosis resulted in bladder stone formation. The stone was larger than 2.5 cm and open vesicolithotomy was therefore selected as the best and safest treatment choice. His symptoms disappeared after surgery. Thorough metabolic and environmental evaluations of such cases are required on an individual basis. Bladder stones should be considered as a possible diagnosis in children presenting with urinary incontinence.

    Job's syndrome (hyper IgE syndrome) is a very rare primary immunodeficiency disease that has an annual approximate incidence of less than 1/1,000,000. This manuscript aims to provide education regarding diagnosis and management strategies of this syndrome worldwide. A 6-year-old boy was seen at the clinic secondary to persistent pruritus interfering with sleep. At the age of 2 months, the patient developed diffuse eczematous and desquamating skin lesions. He was subsequently diagnosed with atopic dermatitis and managed conservatively. From 2 months to 7 years of age, intermittent exacerbations of dermatitis persisted despite an aggressive treatment regimen. The serum IgE level increased exponentially over a period of 7 years, with a peak value of 57,400 IU/ml. Molecular genetic testing revealed a dominant negative mutation within the SH2 domain of the Signal Transducer and Activator of Transcription (STAT3) gene. The patient was subsequently diagnosed with Job's syndrome. Management included proper skin care, prophylactic antibiotics, immunomodulating agents, and psychotherapy. Job's syndrome can often go unrecognized and masquerade as atopic dermatitis. Therefore, genetic testing for this condition should be obtained in all patients with treatment-refractory AD. Additionally, psychotherapy can be a successful management strategy for the grating psychological impact that can be imposed on children with excessive pruritus.

    Takayusu's disease is a rare disease affecting women predominantly during the child- bearing age. It is a primary vasculitis condition of large-vessels that responds well to steroid therapy. Immunosuppressives and vascular reconstruction may be needed as necessary. Reference was made to the case note of this young boy who was being co-managed by cardiology and vascular clinics. The diagnosis of Takayasu's disease was confirmed by the rheumatology unit and appropriate literature search was done. Takayusu's disease responds well to steroid therapy as exemplified by this patient. There was no relapse of the active inflammation after six months of steroid therapy. A high index of suspicion must be exercise in diagnosing Takayasu's disease. It could be difficult to have a clue early in the disease process because of non-specific presentations. Appropriate referral should however be made to Rheumatologist when the diagnosis is suspected. This will go a long way in delaying the morbidity that is associated with this rare disease.

  15. Boys or girls? Parents' preferences and sex control.

    Science.gov (United States)

    Williamson, N E

    1978-01-01

    Recent evidence from the U.S. and from other selected countries is examined on parent sex preferences for their children and how strongly these are held. This involves the significance of these preferences, the social and economic conditions that foster different types of preferences, and how different individuals and societies deal with them. The traditional preference for boys appears to remain nearly universal, which runs contrary to the ideal of "every child a wanted child," and also presents an obstacle to desired declines in fertility in developing countries where sons are still perceived as needed for economic and emotional security. This tendency has been turned around in Japan, Singapore, Hong Kong, and the U.S., where small families are now the ideal. 3 basic approaches to the scientific selection of sex-specific sperm for preselection, the timing of sexual intercourse, the separation of male- and female-bearing sperm followed by artificial insemination, and selective abortion after fetal sex determination indicate that an effective and practical method of sex control is still further off than predicted.

    2016-05-01

    Full Text Available The rapid growth of the natural gas extraction industry in Pennsylvania and neighboring states has stirred concerned citizens to seek ways to collect data on water quality impacts from the extraction activities. As a response to requests from community members, the Alliance for Aquatic Resource Monitoring (ALLARM developed a volunteer-friendly protocol in 2010 for early detection and reporting of surface water contamination by shale gas extraction activities in small streams. To date, ALLARM has trained more than 2,000 volunteers in Pennsylvania, New York, and West Virginia to monitor water quality (conductivity, barium, strontium, and total dissolved solids and physical parameters (stream stage and visual observations prior to, during, and after shale gas wells have been developed. This paper documents the operational models of Public Participation in Scientific Research (PPSR used by ALLARM, describes the volunteer monitoring protocol developed, and examines three years of water quality results from hundreds of monitoring sites in Pennsylvania and New York. The majority of watersheds monitored are small, forested, headwater streams. Results indicate that mean conductivity in streams is strongly and positively related to the percentage of development and the percentage of limestone in the watersheds. Mean conductivity is not significantly related to number or density of drilled wells, although the dataset did not lend itself to finding a signal from shale gas activities because only 20% of the watersheds had wells drilled at the time of sampling. This fact enables the use of these data as baseline data for future documentation of shale gas impacts on water quality. Volunteers have reported multiple cases of visual pollution related to shale gas activities, but have not identified water contamination events based on stream water chemistry. The results of the volunteer dataset are compared with results from the scientific literature, affirming

    2015-12-01

    Youth development programs, such as the Boy Scouts of America, aim to develop positive attributes in youth (e.g., character virtues, prosocial behaviors, and positive civic actions), which are necessary for individuals and societies to flourish. However, few developmental studies have focused on how specific positive attributes develop through participation in programs such as the Boy Scouts of America. As part of the Character and Merit Project, this article examined the developmental trajectories of character and other positive attributes, which are of focal concern of the Boy Scouts of America and the developmental literature. Data were collected from 1398 Scouts (M = 8.59 years, SD = 1.29 years, Range 6.17-11.92 years) and 325 non-Scout boys (M = 9.06 years, SD = 1.43 years, Range 6.20-11.81 years) over five waves of testing across a two-and-half-year period. Latent growth-curve analyses of self-report survey data examined the developmental trajectories of the attributes. Older youth rated themselves lower than younger participants on helpfulness, reverence, thriftiness, and school performance. However, all youth had moderately high self-ratings on all the attributes. Across waves, Scouts' self-ratings increased significantly for cheerfulness, helpfulness, kindness, obedience, trustworthiness, and hopeful future expectations. Non-Scout boys' self-ratings showed no significant change for any attributes except for a significant decrease in religious reverence among non-Scout boys from religious institutions. We discuss implications for positive youth development and for the role of the Boy Scouts of America programming in character development.

    Clinical experiences with 36 males, between the ages of 21 and 60 are described. All of them felt an enduring sexual attraction for boys. Sixteen males were treated for sexual identity conflicts. For eight of them this ended in a positive self-labeling as pedophile, the others had severe problems with accepting sexuality as positive and lustful. Twenty males were treated for identity management problems and counseled how to handle their relationships with boys. Several modalities of interpersonal interaction in man-boy relationships are proposed and the ways conflicts can arise within these frames of reference are explored in counseling and psychotherapy.

  1. Quantifying Hydrological Ecosystem Services of Various Land Covers and Uses on Small Experimental Catchments within the Panama Canal Watershed: The Agua Salud Project

    Crouch, T. D.; Ogden, F. L.; Agua Salud Project

    2011-12-01

    As a part of the Agua Salud Project, a baseline characterization of hydrologic processes on the small catchment scale (~0.24 to 2.0 km2) is assessed across different land uses and covers typical to rural Panama. The land covers being monitored include a mature secondary forest, a disturbed catchment with a mosaic of various aged secondary growth and agricultural use, an active pasture and a monoculture invasive grass site as experimental controls, and two treated catchments that were recently abandoned pastures converted to teak and native species timber plantations. The catchments are found within Panama's protected Soberania National Park and the adjacent headwaters of the Agua Salud and Mendoza Rivers, all part of the greater Panama Canal Watershed. Using hydrological data from the first two and a half years of the project, three main ecosystem services are observed. The forested area exhibited lower storm event peaks, decreased flashiness, and greater stream flow during the dry season compared to the disturbed mosaic site. Lower hydrograph peaks and flashiness mitigate the risk of substantial flood damage during the major flood events generally seen in Panama between October and December. The mature forest (1.35 km2) catchment has shown lower average flood peaks in comparison to the disturbed site. For storm peaks less than 6 mm/hr, flood peaks are on average 51% lower. For storm peaks greater than 6 mm/hr, flood peaks are approximately 40% lower. In 1998, draft restrictions were imposed in the Panama Canal because of a deficit of dry season water after an El Niño-Southern Oscillation resulted in decreased wet season rainfall. The water that is available during the end of the dry season has the potential to insure the full operation of the Canal during El Niño drought years. Toward the end of the dry season (March through May) our data shows that roughly 34% more water was available during a relatively dry year with respect to antecedent wet season rainfall

This study aimed to identify the types of bullying (physical, verbal, psychological, material, virtual or sexual more prevalent in this population and compare bullying among adolescent males and females. We used a questionnaire prepared by the researcher. Participants were 309 students, 142 males and 167 females, from 6th to 8th grade from two schools, one state and one municipal. These results show 27% of participants were involved in episodes of bullying and that the most prevalent type of bullying was verbal, being appointed for 92% of girls and 84% boys; followed by psychological, indicated by 70% of girls and 53% boys. Physical bullying, had 46% of female and 44% male reports, the material was mentioned by 27% of girls and 16% boys. On sexual bullying type was greatest difference between the sexes, suffered by 38% of girls and 16% boys. Only 13% of girls and 12% boys, mentioned suffer the virtual bullying. Corroborating research area, in this study the highest percentage of victims were female and different from the literature girls reported being verbally abused more for boys than for girls.

    To investigate whether weight category (underweight, average weight, overweight, and obese) at age 7.5 predicts bullying involvement at 8.5 years. Models were tested separately for boys and girls to investigate gender differences in association patterns. Prospective cohort study in southwest England. Height and weight were measured in children at age 7.5 (n = 8210). BMI (kg/m2) was used to define underweight, average weight, overweight, and obese children, according to British age and gender specific growth reference data. Overt (n = 7083) and relational (n = 6932) bullying behaviour was assessed in children at age 8.5. After adjustment for parental social class, compared to average weight boys, obese boys were 1.66 (95% CI 1.04 to 2.66) times more likely to be overt bullies and 1.54 (1.12 to 2.13) times more likely to be overt victims. Obese girls were 1.53 (1.09 to 2.15) times more likely to be overt victims compared to average weight girls. Obesity is predictive of bullying involvement for both boys and girls. Preadolescent obese boys and girls are more likely to be victims of bullying because they deviate from appearance ideals. Other obese boys are likely to be bullies, presumably because of their physical dominance in the peer group.

    To analyze the features of boys with congenital gonadotropin deficiency (CGD), and to determine the value of plasma inhibin B and anti-Müllerian hormone (AMH) for predicting testicular function and the effect of testosterone treatment. We followed 19 boys for CGD, including five with Kallmann syndrome. The boys were seen before 14 years of age for micropenis (9 boys) or later for delayed puberty (10 boys). No testis was palpable in the scrotum in 13 patients, bilaterally in seven of them. Luteinizing hormone (LH) peak after a gonadotropin releasing hormone (GnRH) test was between 0.5 and 5.6 U/l. Plasma inhibin B was low in the four patients evaluated at less than 1 year old. AMH was low in one of them and normal in four others. Of the older patients, three lad low plasma inhibin B and four had normal concentrations; plasma AMH was low in three of them and increased in four. Testosterone treatment restored penis length to normal in all patients. Low plasma inhibin B and AMH concentrations may indicate testicular damage in boys with CGD.

    Although toxicological studies have demonstrated an association between exposure to polychlorinated dibenzo-p-dioxins (PCDDs) and adverse developmental and reproductive health effects, human evidence is limited. In particular, the health consequences of childhood and adolescent exposure to PCDDs have been inadequately investigated. Given the animal data and the evidence that children may be more sensitive to PCDDs than adults, we conducted a pilot study to determine exposure levels among adolescents living in Chapaevsk, Russia, where environmental levels of dioxin are high. Chapaevsk, a town of approximately 80,000 residents, is 43 kilometers southwest of Samara on the Chapaevsk River, a tributary to the Volga. Half of the town area of 187 km{sup 2} is occupied by industrial manufacturing facilities employing almost half of the city's work-force. Our pilot study in Chapaevsk was designed to determine the feasibility of studying the relationship of exposure to PCDDs and PCDFs with somatic growth, pubertal development, and hypothalamicpituitary- gonadal function among peri-pubertal Chapaevsk boys. Aims of the pilot study included identifying potential predictors of serum levels of PCDDs and PCDFs among adolescent boys and assessing the relation of these measures with genito-urinary development and adolescent sexual maturation. Due to the high expense involved in measuring serum PCDDs and PCDFs, these analytes and coplanar and mono-ortho PCBs were measured in serum from a small subset (n=30) of boys participating in the pilot. Potential predictors of these 30 boys' serum dioxin levels and the relationship of dioxin levels with sexual development were assessed. Throughout the remainder of this report, the term dioxins will include PCDDs, PCDFs, and co-planar PCBs.

  19. Boys and girls "doing science" and "doing gender"

    Science.gov (United States)

    Cervoni, Cleti

    The gender gap in achievement in science continues to plague science educators (AAAS, 2001). Strategies to close this gap have defined the problem in terms of girls' lack of interest or their inability to survive in science classrooms. Recent feminist scholarship has re-centered this problem of gender inequity not on girls, but on the nature of science and how it is taught in schools (Birke, 1986; Parker, 1997). Lesley Parker (1997) argues that it is schools that need to change and recommends a gender-inclusive science curriculum for schools. My dissertation argues for a new framework and research agenda for understanding the relationship between gender and science in schools. My study examines the gender dynamics of how unequal gender relations are negotiated, resisted and sustained in the context of a second grade science classroom. In examining the gender dynamics between the boys and the girls in a science classroom, I found that the boys positioned the girls as their assistants, as incompetent in science, as weak in contrast to the boys, and in need of the boys' help and protection. These discourses functioned to create and sustain unequal gender relations in the classroom. The girls responded in paradoxical ways to the boys' positioning of them. They resisted the boys by: (a) ignoring them; (b) using a domestic discourse to negotiate/gain more power; (c) appropriating teacher authority; or (d) using sexuality to embarrass and silence the boys. The girls also deferred to the boys as experts in science. In these ways, the girls themselves contributed to maintaining unequal gender relations in the classroom. I found that the classroom context is a site of struggle for both boys and girls as they seek to secure a place in the social hierarchy of the classroom. For the boys, masculinity is strong and powerful yet fragile and vulnerable. The girls struggle in holding multiple images of femininity. Examining gender dynamics through positioning and negotiation for

    This report describes in details the project of the installation of a small-scale hydroelectric power plant on the river Areuse in Switzerland. Located on a 4 m high waterfall the plant includes a 10-13 m{sup 3}/s Kaplan turbine, which should deliver roughly 1.6 GWh/year for an installed power of about 500 kVA. The authors insist on the ecological aspect of the project. The plant will be built underground; the river track will be practically unchanged and the existing fish ladder maintained. The report includes maps and pictures of the site as well as technical drawings of the installation. An economic analysis of the project is presented and its viability is discussed. Finally, the authors state that the energy produced by this plant will certainly be certified under one of the Swiss labels 'naturemade star' or 'naturemade basic', in the framework of the federal government's promotion of renewable energy sources.

    Some boys with autism spectrum disorder (ASD) and boys with fragile X syndrome and a codiagnosis of ASD (FXS+ASD) have impairments in expressive grammatical abilities. The current study compared grammatical performance in these 2 groups of school-age boys. Thirty-seven boys similar on mean length of utterance participated in the current study (FXS: n = 19, ASD: n = 18). Participants completed an ASD assessment, nonverbal IQ testing, and conversation language samples. Convergent validity of a sentence imitation task with a norm-referenced assessment of grammar was examined in addition to divergent validity of the measures with nonverbal IQ and vocabulary comprehension and production. The boys with ASD outperformed the boys with FXS+ASD on the norm-referenced assessment of "be," and effect sizes indicate that the boys with ASD had better performance on past tense probes on the sentence imitation task and "do" on the norm-referenced assessment. The two measures of grammar had good convergent validity except for copula and auxiliary "be" and "do." Grammatical performance was not correlated with nonverbal IQ, and trends indicate a relationship between vocabulary and grammar. Despite being similar on mean length of utterance, there were group differences on grammatical performance. The sentence imitation task had good convergent validity with a norm-referenced assessment of grammar for the third-person singular and past tense probes and therefore could be an inexpensive and valid tool to use clinically for these populations. Future research should continue to refine this task, particularly for the probes with high rates of unscorable responses (i.e., "be" and "do").

Most of the boys lived in Ontario, although a few came from other Canadian provinces.Methods – Library school students who were registered in a Literature for Children and Young Adults class interviewed children and young adults about their reading and information practice as part of a “Book Ownership Case Study” assignment. The researcher also interviewed children and young adults, for a total of 137 case studies. For the purpose of this article, a data subset for the 43 boys included in the larger project was analyzed. The boys ranged in age from four to twelve years. The mean age was eight and the median age was nine. The theoretical perspective of reader response theory was used to situate the study. This theory has the relationship between the text and the reader as its focus, and it suggests that to understand the reading habits of boys, there needs to be recognition that the experts about their reading are the boys themselves. The interviews, which explored reading preferences and practices, were qualitative, semi‐structured, and took thirty minutes to complete. In addition to the interview, each boy’s personal book and information material collection was inventoried. The researcher used a grounded theory approach to analyze the inventory and interview data to pull out themes related to the

    2004-05-01

    The current study examined the best friendships of aggressive and nonaggressive boys (N = 96 boys, 48 dyads, mean age = 10.6 years). Friends completed self-report measures of friendship quality, and their interactions were observed in situations that required conflict management and provided opportunities for rule-breaking behavior. Although there were no differences in boys' self-reports of friendship quality, observers rated nonaggressive boys and their friends as showing greater positive engagement, on-task behavior, and reciprocity in their interactions compared with aggressive boys and their friends. Aggressive boys and their friends provided more enticement for rule violations and engaged in more rule-breaking behavior than did nonaggressive boys and their friends. Also, the intensity of negative affect in observed conflicts between aggressive boys and their friends was greater than that between nonaggressive boys and their friends. The findings suggest that friendships may provide different developmental contexts for aggressive and nonaggressive boys. Copyright 2003 Elsevier, Inc.

    Full Text Available Background. The epidemic of the XXI century – a disease that threatens through development of other ailments, caused by pathological accumulation of adipose tissue in the body, beyond the physiological needs and adaptability – the obesity. A significant number of diseases are largely a consequence of obesity, and despite the fact that it mainly occurs in adults, that problem may start influencing our health from an early age. In childhood and adolescence the most common form is simple obesity, and frequency of occurrence shows significant growing trend, regardless of gender. The prevalence of obesity in early stages of life is associated with a significant probability of a continuation of or increase in adulthood, therefore one should look for the onset of obesity in childhood. The results of studies and projections show steady growth in the number of overweight and obese in populations of developing countries and developed economies, including Poland. Therefore it is important to continuously monitor body weight and degree of fatness of children and adolescents. Material and methods. The study was conducted in 2001 and 2002 in six rural primary schools from the Copper Mining Region and in all three primary schools from Polkowice. More measurements were made in 2008 and 2010. The total number of 7-year old boys was 277. The measurements covered Body height, Body weight, Lean Body Mass, Total Body Water and Total Body Fat. These data were collected with the use of anthropometer, body scale and FUTREX 5000, the optical body composition analyzer. Measurements were necessary to get the BMI. Results. Based on analysis, it was observed that the height and weight of 7-year-old boys from the Copper Mining Region has increased compared to the first series of tests. The BMI and amount of body fat have also increased. This situation was observed both in rural and urban environment. There was a difference in body fat percentage. Lower values were

    On the basis of the widespread belief that emotions underpin psychological adjustment, the authors tested 3 predicted relations between externalizing problems and anger, internalizing problems and fear and sadness, and the absence of externalizing problems and social-moral emotion (embarrassment). Seventy adolescent boys were classified into 1 of 4 comparison groups on the basis of teacher reports using a behavior problem checklist: internalizers, externalizers, mixed (both internalizers and externalizers), and nondisordered boys. The authors coded the facial expressions of emotion shown by the boys during a structured social interaction. Results supported the 3 hypotheses: (a) Externalizing adolescents showed increased facial expressions of anger, (b) on 1 measure internalizing adolescents showed increased facial expressions of fear, and (c) the absence of externalizing problems (or nondisordered classification) was related to increased displays of embarrassment. Discussion focused on the relations of these findings to hypotheses concerning the role of impulse control in antisocial behavior.

    Boys' lacrosse has one of the highest rates of concussion among boys' high school sports. A thorough understanding of injury mechanisms and game situations associated with concussions in boys' high school lacrosse is necessary to target injury prevention efforts. To characterize common game-play scenarios and mechanisms of injury associated with concussions in boys' high school lacrosse using game video. Descriptive epidemiological study. In 25 public high schools of a single school system, 518 boys' lacrosse games were videotaped by trained videographers during the 2008 and 2009 seasons. Video of concussion incidents was examined to identify game characteristics and injury mechanisms using a lacrosse-specific coding instrument. A total of 34 concussions were captured on video. All concussions resulted from player-to-player bodily contact. Players were most often injured when contact was unanticipated or players were defenseless (n = 19; 56%), attempting to pick up a loose ball (n = 16; 47%), and/or ball handling (n = 14; 41%). Most frequently, the striking player's head (n = 27; 79%) was involved in the collision, and the struck player's head was the initial point of impact in 20 incidents (59%). In 68% (n = 23) of cases, a subsequent impact with the playing surface occurred immediately after the initial impact. A penalty was called in 26% (n = 9) of collisions. Player-to-player contact was the mechanism for all concussions. Most commonly, injured players were unaware of the pending contact, and the striking player used his head to initiate contact. Further investigation of preventive measures such as education of coaches and officials and enforcement of rules designed to prevent intentional head-to-head contact is warranted to reduce the incidence of concussions in boys' lacrosse.

  16. The pool chlorine hypothesis and asthma among boys.

    Swimming pool sanitation has largely been concerned with the microbiological quality of pool water, which is normally treated using a number of chlorine products. Recent studies have pointed to the potential hazards of chlorine by-products to the respiratory epithelium, particularly in indoor, poorly ventilated, pools. The aim of our study was to elucidate whether chronic exposure to indoor chlorinated swimming pools was associated with an increased likelihood of the development of asthma in boys. METHODS: The subjects were boys aged between 6 and 12 years. Data was collected by means of parental responses to a standardized asthma questionnaire (ISAAC: International Study of Asthma and Allergies in Childhood), supplemented with additional questions regarding frequency of attendance, number of years attendance, whether the child is a swimming team member. The questionnaire return rate was 71\\/% (n = 121). 23 boys were excluded on the basis that they had asthma before they started swimming (n = 97). There was a significant association between number of years a boy had been swimming and the likelihood of wheezing in the last 12 months (p = 0.009; OR = 1.351; 95% CI = 1.077-1.693) and diagnosed asthma (p = 0.046; OR = 1.299; 95% CI = 1.004-1.506). The greater the number the number of years a boy had been attending an indoor, chlorinated pool, the greater the likelihood of wheezing in the last 12 months or "had asthma". Age, parental smoking habits and being a swimming team member had no association with any of the asthma variables examined. Swimming pool attendance may be a risk factor in asthma in boys.

    Adolescence is a period of transition during which a person is neither considered a child nor an adult. As little is known about adolescent boys' perceptions, norms, role models and gender relations that influence their male identity and behaviour, this qualitative study was conducted. Data were drawn from seven FGDs and twelve mails of adolescent boys (15-19 years old) residing in two townships outside Lusaka and Kitwe in Zambia. Findings show that growing up to a man entails a certain level of ambiguity and contradictory perceptions in terms of supposedly appropriate social and sexual behaviour but indicates a few alternatives. Based on the findings, we recommend that the information gap, misconceptions and anxiety among boys regarding their male identity should be addressed. The respondents suggested that an educational programme that will pay due attention to their needs and answer their questions should be designed and implemented with active involvement of male adolescent peers.

    In the food industry, injuries due to food poisoning have been increasing. Especially the mass outbreak of food poisoning by Escherichia coli such as O-157 in 1996 gave warning on the importance of food sanitation management. Public efforts such as the Hazard Analysis and Critical Control Point (HACCP) system have been made to prevent food poisoning. Recently, disinfection made by electrolyzing water with some salt added has attracted attention. Fuji Electric has developed the generator 'SaniBoy' that produces weak alkaline electrolyzed water without wasting water. The environment-friendly 'SaniBoy' will contribute to sanitation in various fields. (author)

    This PowerPoint presentation discussed initiatives and strategies adopted by the Canadian Wind Energy Association (CanWEA) to support the development of Canada's small wind market. The general public has shown a significant interest in small wind projects of 300 kW. Studies have demonstrated that familiarity and comfort with small wind projects can help to ensure the successful implementation of larger wind projects. Small wind markets include residential, farming and commercial, and remote community applications. The results of CanWEA market survey show that the small wind market grew by 78 percent in 2008 over 2007, and again in 2009 by 32 percent over 2008. The average turbine size is 1 kW. A total of 11,000 turbines were purchased in 2007 and 2008. Global small wind market growth increased by 110 percent in 2008, and the average turbine size was 2.4 kW. Eighty-seven percent of the turbines made by Canadian mid-size wind turbine manufacturers are exported, and there is now a significant risk that Canada will lose its competitive advantage in small wind manufacturing as financial incentives have not been implemented. American and Canadian-based small wind manufacturers were listed, and small wind policies were reviewed. The presentation concluded with a set of recommendations for future incentives, educational programs and legislation. tabs., figs.

    Initiation and progression of puberty requires concerted action of hypothalamic activating and inhibiting factors. Recently, cases of familial central precocious puberty have been linked to loss-of-function mutations of makorin RING-finger protein 3 (MKRN3) indicating a pivotal inhibitory role of the protein on GnRH secretion. To investigate peripubertal circulating MKRN3 levels in healthy boys. Population-based longitudinal study in healthy Danish boys. General community. Healthy boys (n = 60) aged (median [range]) 9.3 (5.8-11.8) years at baseline followed for 6.0 (0.5-7.6) years (2006-2014) with blood sampling every 6 months. None. Serum levels of MKRN3: 623 samples, median (range) 12 (2-14) per boy. MKRN3 levels declined before onset of puberty; the geometric mean (95% confidence interval) 5 years before onset of puberty vs last visit before onset of puberty was 216 (169-272) pg/mL vs 128 (118-139) pg/mL (P puberty progressed. MKRN3 levels were not associated with age at onset of puberty. Declining MKRN3 before pubertal onset support MKRN3 as an inhibitor of GnRH secretion during midchildhood.

    2013-12-01

    In developed societies levels of daily physical activity (PA) among school-age children are decreasing. This implies risk factors for cardiovascular and metabolic diseases. Specific strategies to improve levels of PA are needed. In prepubertal boys there is evidence that strength training increases spontaneous PA outside of training. A total of 102 schoolchildren (age 10-14 years) in Switzerland were randomly assigned to physical education classes or to participate twice weekly at a guided strength training program for 19 weeks. Spontaneous PA energy expenditure (PAEE; 3axial accelerometry for 7 days), leg and arm strength, and body composition (dual energy radiograph absorptiometry) were measured at baseline, after 19 weeks of training intervention, and after 3 months of washout. There were no significant differences between the groups at baseline. In the intervention group, PAEE increased by 10% from baseline to end of training in boys (P = .02), but not in girls. Leg and arm strength were increased owing to training intervention in both boys and girls. All other variables were unchanged. Baseline PAEE was significantly negatively correlated with changes of PAEE. Targeted strength training significantly increases daily spontaneous PA behavior in boys. The less active children showed the greatest increase in spontaneous PAEE. Girls showed a similar increase in strength, but not in spontaneous PAEE. This may be explained by their earlier pubertal development. Strength training may be a promising strategy in schools to counteract decreasing levels of PA.

    The aim of this study was to examine the associations between lifetime traumatic experiences and leisure physical inactivity among adolescent boys and to determine to what extent those associations are mediated by posttraumatic stress symptoms, unhealthy behaviors (smoking, alcohol use), the daily consumption of fresh fruit, and sense of coherence. A self-administered questionnaire combining 3 instruments measured leisure physical activity level (Godin and Shephard), symptoms of posttraumatic stress (IES-revised), lifetime traumatic experiences, sense of coherence (SOC-13, from Antonovsky), and behavioral and dietary patterns in a representative sample of eighth grade boys from a number of Kaunas, Lithuania, secondary schools (N = 885; response rate 88.6%). Fifty-six point eight percent of boys had experienced at least 1 lifetime traumatic event, with a 20.5% prevalence of PTS symptoms, and 5.4% were inactive during leisure time. In the logistic regression models, leisure physical inactivity was associated with lifetime traumatic experiences (adjusted OR = 2.33; 95% CI: 1.09-4.98). Sense of coherence and posttraumatic stress symptoms did not mediate those associations. Less-than-daily consumption of fresh fruit showed an independent effect, while smoking and weekly consumption of alcohol did not. Consistent associations between lifetime traumatic experiences and leisure physical inactivity among adolescent boys indicate that the presence of lifetime traumatic events should be taken into account when employing intervention and prevention programs on unhealthy lifestyles (physical inactivity, smoking, and alcohol).

    The purpose of this study was to analyze in which physical capabilities boys and girls are closer or distant. An additional objective was to find which of the body fat, physical activity, and somatotype factors have a greater effect on prepubescent children's physical fitness. This was a cross-sectional study involving 312 children (10.8 ± 0.4 years). The physical fitness assessment employed sets of aerobic fitness, strength, flexibility, speed, agility, and balance. The boys presented higher values in all selected tests, except tests of balance and flexibility, in which girls scored better. Gender differences in the physical fitness were greatest in the explosive strength of upper (p ≤ 0.01, η(p)(2) = 0.09) and lower limbs (p ≤ 0.01, η(p)(2) = 0.08), although with a medium-size effect of gender, and smaller in the abdominal (p > 0.05, η(p)(2) = 0.007) and upper limbs (p > 0.05, η(p)(2) = 0.003) muscular endurance, and trunk extensor strength and flexibility (p > 0.05, η(p)(2) = 0.001). The endomorphic (p ≤ 0.01, η(p)(2) = 0.26) in the girls, and the ectomorphic (p ≤ 0.01, η(p)(2) = 0.31) and mesomorphic (p ≤ 0.01, η(p)(2) = 0.26) in the boys, had the high-sized effect on the physical fitness. The physical activity in the girls, and the endomorphic and body fat in the boys, did not have a significant effect. These findings can help in the planning of activities that take into account the success and motivation of both boys and girls and thus increase levels of physical activity and physical fitness at school. However, in prepubescent children, one cannot neglect the influence of genetic determinism, observed from the morphoconstitutional point of view.

    Dams influence directly the process of fish migration. Assessing the impact of these infrastructure and direct research for that purpose minimize environmental impacts resulting from projects on biodiversity. Through computer models and probability logistic regressions of occurrence that take into account geomorphologic parameters (elevation and basin area) was obtained a standard distribution model of migratory fishes species in the upper Uruguay river basin (RS/SC) with high calibration (84.39% of adherence). The computational modelling significantly increases the knowledge about methodologies for evaluate environmental impacts caused by small and large dams and applicability in other basins. (author)

    Technique testing of quality the transparent component of optical devices with application of self-focusing effect is offered. In measurement of small wavefront distortions a method of comparison of laser beam parameters before and after passage of a tested optical element is used. With the purpose of increase of sensitivity it is offered for overcoming negative diffraction action to use self-focusing effect of probe beam. Application of self-focusing effect allows to reach sensitivity no less than (lambda) /600 and in future up to (lambda) /3000. On simple samples experimental checks of a method are made.

    2011-01-01

    We propose a new scanner for small animal Positron Emission Tomography (PET) based on stacks of double sided silicon detectors. Each stack is made of 40 planar detectors with dimension 60x60x1 mm 3 and 128 orthogonal strips on both sides to read the two coordinates of interaction, the third being the detector number in the stack. Multiple interactions in a stack are discarded by an exclusive OR applied between each detector plane of a stack. In this way we achieve a precise determination of the interaction point of the two 511 keV photons. The reduced dimensions of the scanner also improve the solid angle coverage resulting in a high sensitivity. Preliminary results were obtained with MEGA prototype tracker (11 double sided Si detector layers), divided into two stacks 2 cm apart made of, respectively, 5 and 6 prototype layers, placing a small spherical 22 Na source in different positions. We report on the results, spatial resolution, imaging and timing performances obtained with double sided silicon detectors, manufactured by ITC-FBK, having an active area of 3x3 cm 2 , thickness of 1 mm and a strip pitch of 500μm. Two different strip widths of 300 and 200μm equipped with 64 orthogonal p and n strips on opposite sides were read out with the VATAGP2.5 ASIC, a 128-channel 'general purpose' charge sensitive amplifier.

    A major problem for sustainable development in the Amazon is the difficulty of supplying electric power to isolated communities. This problem has been a major obstacle to the productive activities of such communities, especially extractive and agricultural. One way to solve this problem would be to use the small rivers in the region by implementing Micro Hydroelectric Power Plants. In this paper, it was suggested a run-of-river scheme, based on a survey of energy demand and the local hydrological and topographical characteristics. Assessments of environmental, hydropower and economic aspects were developed. Also, the power supply option existing in the community - diesel generator - was analyzed. By comparing the analyses of the Micro hydroelectric power plants (MHP) to those of the diesel generator, the environmental and economic advantage of the MHP was confirmed, thus demonstrating that these can be considered for solving, in a sustainable manner, the problem of shortage of electric power supply verified in the small communities in the Amazon.

    Children with language impairment (LI) experience social difficulties, including conflict management. This paper is therefore motivated to examine behavioural processes guiding preschool peer conflict progression, which ultimately contributes to overall development. To describe behavioural sequences in conflicts between children with typically developing language (TL) and between children with LI. Attention is particularly focused on the conflict resolution strategy reconciliation, i.e. friendly contact between former opponents shortly following conflict termination. It is hypothesized that children with LI, with weaker language skills, experience difficulties attaining effective reconciliation. Unstructured play of 11 boys with LI (4-7-years-old), at a specialized language preschool, and 20 TL boys (4-6-years-old), at mainstream preschools, were video filmed. Conflicts were identified and recorded according to a validated coding system. Recorded conflict details included behavioural sequences constituting conflict cause (conflict period) and in the post-conflict period, reconciliatory behaviours that were classified into six 'categories' (Invitation to play, Body contact, Object offer, Verbal apology, Self-ridicule, Cognition, i.e. offering privileges/negotiating) and the verbal character of accepted behaviours were determined. The mean proportion of individual target children's conflicts in which specific behavioural sequences had occurred were calculated and thereafter compared between and within the groups. Boys with LI reconcile fewer conflicts than TL boys (LI: 47.3 +/- 4.5%; TL: 63.6 +/- 2.0%). Contributory factors include the occurrence of conflicts caused by aberrance, i.e. conflicts initiated by inappropriate behavioural play intensities (i.e. 'a pillow fight' where one partner swings so intensively the other partner cannot participate as a player in the game) and protests that are no longer directed to the opponent within reciprocal exchanges, but

    The objective of this test program is the performance and economic evaluation of a pre charged-pulse jet filter as the principal particulate control device for a commercial or industrial scale coal fired combustor. Performance factors that will be considered are the effects of particle charge, air/cloth ratio, fabric types, percent humidity and inlet particulate loading on fine particle collection efficiency, and pressure drop. Economic factors that will be considered are capital costs, energy and other operating costs, and maintenance costs. The program will result in a recommendation regarding the relative suitability of the pre charged pulse-jet filter for small combustor particulate control, as compared to other control devices. Fine particle control capability, ease of operation, and overall economics will be taken into consideration in making comparisons.

  1. Occipital cephalocele with neural crest remnants? Radiological and pathological findings in a newborn boy.

    2016-06-01

    A cephalocele is a congenital anomaly involving the herniation of intracranial tissue from a skull defect. The sac containing the central nervous system (CNS) with the ventricle system is called the encephalocystocele. An atretic cephalocele is thought to be an abortive form of cephalocele, and the essential nature is still controversial. Here, we report the case of a newborn boy with an occipital cephalocele containing a small cystic component which was composed of ependymal cells and the immature CNS tissue. A newborn boy was admitted to our hospital because of an occipital mass, which was about 2.5 cm in diameter, located at the posterior midline, and covered with alopetic skin without CSF leakage. He had a cleft palate. Magnetic resonance imaging (MRI) clearly showed an occipital cephalocele with a tiny cystic component connecting to the subarachnoid space. MRI also showed mild hydrocephalus, hypoplasia of the corpus callosum and tentorium cerebelli, dropping down of the bilateral occipital lobes and vermicular agenesis. We performed the extirpation of the subscalp module under general anesthesia and histologically examined the resected mass. On immunohistopathological examination, most part of the subscalp module was fibrous tissue with numerous vessels and meningeal origin cells. In a small part of the innermost layer, we found a small island consisting of CNS tissue and a tiny cyst lined with a single layer of ependymal cells. Based on radiological and immunohistopathological findings, we speculate that the cystic component at the base of the nodule seems to correspond to neural crest remnants but not to true herniation of the brain and cerebral ventricles.

  2. Girls in detail, boys in shape: gender differences when drawing cubes in depth.

    Lange-Küttner, C; Ebersbach, M

    2013-08-01

    The current study tested gender differences in the developmental transition from drawing cubes in two- versus three dimensions (3D), and investigated the underlying spatial abilities. Six- to nine-year-old children (N = 97) drew two occluding model cubes and solved several other spatial tasks. Girls more often unfolded the various sides of the cubes into a layout, also called diagrammatic cube drawing (object design detail). In girls, the best predictor for drawing the cubes was Mental Rotation Test (MRT) accuracy. In contrast, boys were more likely to preserve the optical appearance of the cube array. Their drawing in 3D was best predicted by MRT reaction time and the Embedded Figures Test (EFT). This confirmed boys' stronger focus on the contours of an object silhouette (object shape). It is discussed whether the two gender-specific approaches to drawing in three dimensions reflect two sides of the appearance-reality distinction in drawing, that is graphic syntax of object design features versus visual perception of projective space. © 2012 The British Psychological Society.

    The purpose of this study was to validate derived T2 maps as an objective measure of muscular fat for discrimination between boys with Duchenne muscular dystrophy (DMD) and healthy boys. Forty-two boys with DMD (mean age, 9.9 years) and 31 healthy boys (mean age, 11.4 years) were included in the study. Age, body mass index, and clinical function scale grade were evaluated. T1-weighted MR images and T2 maps with and without fat suppression were obtained. Fatty infiltration was graded 0-4 on T1-weighted images, and derived T2 fat values (difference between mean T2 values from T2 maps with and without fat suppression) of the gluteus maximus and vastus lateralis muscles were calculated. Group comparisons were performed. The upper limit of the 95% reference interval of T2 fat values from the control group was applied. There was no significant difference in age or body mass index between groups. All healthy boys and 19 boys (45.2%) with DMD had a normal clinical function scale grade. Grade 1 fatty infiltration was seen in 90.3% (gluteus maximus) and 71.0% (vastus lateralis) of healthy boys versus 33.3% (gluteus maximus) and 52.4% (vastus lateralis) of boys with DMD. T2 fat values of boys with DMD were significantly longer than in the control group (p < 0.001). Using a 95% reference interval for healthy boys for the gluteus maximus (28.3 milliseconds) allowed complete separation from boys with DMD (100% sensitivity, 100% specificity), whereas the values for the vastus lateralis (7.28 milliseconds) resulted in 83.3% sensitivity and 100% specificity. Measurement of muscular fat with T2 maps is accurate for differentiating boys with DMD from healthy boys.

    We report here on a 6-year-old boy referred to the laboratory for karyotyping and SHOX microdeletion testing. The most significant clinical findings in this boy were small stature, Madelung deformity, facial dysmorphism, mild mental retardation and behavioral problems. R-, G- and RTBG-banding chromosome analysis showed a normal male karyotype. Fine molecular characterization, by FISH, of terminal Xp microdeletion revealed an associated partial duplication. Further refinement of the molecular analysis indicated an inverted duplication of the Xp22.31-Xp22.32 (13.7 Mb) region including the STS, VCX-A and KAL1 genes, associated with a terminal Xp deletion Xp22.33-Xpter (3.6 Mb) encompassing the SHOX and ARSE genes. Such rearrangements have been characterized for other chromosomal pairs, but this is the first reported male patient involving the short arm of the X chromosome. Molecular analysis of the maternal and patient's microsatellite markers showed interchromatid mispairing leading to non-allelic homologous recombination to be the most likely mechanism underlying this rearrangement. This case highlights the importance of clinically driven FISH investigations in order to uncover cryptic micro-rearrangements. Copyright (c) 2007 Wiley-Liss, Inc.

    Structural materials, such as ferritic and austenitic steels or aluminium alloys used in the nuclear and aircraft industry, are subjected to external operational loads in different environments. Adopting a damage tolerant design principle, understanding the growth of preexisting or newly formed cracks under these conditions is of prime relevance to prevent extensive crack propagation and failure of the component. Within this framework, the characterization of early stages of the damage processes, as nucleation, growth and coalescence of micro-voids and the evolution of the spatial dislocation distribution (dislocation patterning) is a particularly challenging aspect. It was the objective of the work performed to investigate the damage structure near a crack tip by means of small angle X-ray scattering (SAXS). Pre-cracked fracture mechanics standard specimens from different aluminium alloys and steels were loaded up to different amounts of crack growth. From the crack tip range samples of 100 to 200 μm thickness were prepared and a small region around the crack tip was scanned using a microfocused Synchrotron beam. The SAXS experiments were performed at different Synchrotron sources and equipments with different beam cross section, scan step width and X-ray energy. Additionally, the investigation was completed by other methods like X-ray diffraction, X-ray imaging diffraction technique (MAXIM), transmission electron microscopy, scanning electron microscopy, and positron annihilation spectroscopy. The SAXS intensity pattern shows location-related effects. Potential SAXS parameters to characterize the damage are the integral intensity, a fractal dimension parameter and a value determined from the ratio of the intensity vertical and horizontal to the direction of crack growth. Above all, the last parameter is suitable to depict the damage zone around the crack tip. It is robust and applicable even for a material which exhibits an anisotropic SAXS pattern in the

    The experiences of small and midsized enterprises (SME) with medical rehabilitation were investigated in the KoRB-Study (KoRB= KOoperation Rehabilitation und Betrieb) for the first time. Opportunities for a targeted cooperation between the statutory pension insurance and these enterprises were explored. Based on explorative interviews, Westphalian employers, members of the works council, occupational health practitioners and employees were interrogated about the image of and their appreciation of medical rehabilitation in the work setting. Experience with rehabilitation and the level of information on rehabilitation were recorded as well as the compatibility of rehabilitation with operative processes in the working site. In addition rehab hospitals were asked about their experience in cooperating with enterprises. 697 employers of small and midsized enterprises, 458 members of the works councils, 73 occupational health practitioners, 47 rehab hospitals and 3 509 employees, who are members of the German Pension Fund of Westphalia, took part in the survey. Especially employers perceived rehabilitation positively and reported good experiences. Among the employees, those who had taken part in rehabilitation showed the highest appreciation. Occupational health practitioners were more restrained in their appraisal. Some of them complained about a lack of sustainability. The different target groups of the survey felt differently well informed about rehabilitation - best ratings came from the occupational health practitioners, worst ratings from the employees. All groups would welcome more accessible information in case of need. Medical rehabilitation in its standard form of "3 weeks full-time" often causes severe logistic problems in SME (e. g., replacement of employee, loss of experience). However the financial burden is perceived as less problematic. Employers favour alternative rehab models, which allow part-time working. Many employees, who expressed a need for

He had 2–3 admissions per year due to fall and had a history of fractures at his right ankle, left femur and three times at his left elbow. On further questioning, it was found that he was born via spontaneous vaginal delivery. Antenatal and postnatal periods were uneventful and neonatal and development histories were similar to other siblings. No similar illnesses, history of osteoporosis, recurrent fractures or eye problem were found in the family. Examination showed that he was a thin-built boy with a normal gait, vision, speech and hearing. It was noted he had an eye abnormality (Figure 1, but the ear, nose, throat and dentition were normal. The cranial nerve and other neurological tests were also normal. There was no joint hypermobility and the other systems and pure tone audiogram were normal.

    The aim of this pilot study was to evaluate respiratory behavior and respiratory indices of poultry workers on family-owned, poultry farms with 10 or less employees in North Carolina. A field study was conducted to collect data on participants (N = 24) using spirometry, fractional exhaled nitric oxide (Feno), and an interviewer-administered questionnaire. The majority of workers (76%) ranked respiratory protection as being important, yet 48% reported never or rarely wearing respiratory protection when working in dusty conditions. A large percent of workers reported eye (55%) and nasal (50%) irritation and dry cough (50%). On average, pulmonary lung function and Feno tests were normal among nonsmokers. In bivariate analysis, significant associations were identified between working 7 days on the farm (P = .01), with eye irritation, and working 5 or fewer years in poultry farming (P = .01). Poultry workers on family-owned farms spend a considerable amount of work time in poultry houses and report acute respiratory-related health symptoms. Administrative controls among small, family-owned poultry farms are necessary to improve and promote safety and health to its employees.

    This report describes in details the project of the installation of a small-scale hydroelectric power plant on the river Areuse in Switzerland. Located on a 4 m high waterfall the plant includes a 10-13 m{sup 3}/s Kaplan turbine, which should deliver roughly 1.6 GWh/year for an installed power of about 500 kVA. The authors insist on the ecological aspect of the project. The plant will be built underground; the river track will be practically unchanged and the existing fish ladder maintained. The report includes maps and pictures of the site as well as technical drawings of the installation. An economic analysis of the project is presented and its viability is discussed. Finally, the authors state that the energy produced by this plant will certainly be certified under one of the Swiss labels 'naturemade star' or 'naturemade basic', in the framework of the federal government's promotion of renewable energy sources.

    Early detection examinations take place from birth to the age of 6 years. The youth screening is a continuation of the screening of the "U-series" and should be carried out between the age of 12-15 and 16-17, respectively. Afterwards adolescent girls have good contact with a gynecologist, but adolescent boys usually do not have a medical contact person who they can trust in. To evaluate the state of knowledge on boys' health, a 15-item comprehensive knowledge survey was conducted among ninth grade students at 7 secondary schools (Gymnasien) in North Rhine-Westphalia. The knowledge survey took place at three specified times (before, immediately after and approximately 3 months after adolescent sexual education classes). Only completed questionnaires were analyzed and evaluated in a gender-specific manner. Overall, 459 students participated from March-September 2017. Before sexual education instruction, about half of all questions were answered correctly by the students. Immediately after class, the proportion increased by a factor of 1.5 to a total of 79.24%. Then 2-3 months after the class, the percentage was 69.67%. Considering gender separately, this resulted in an increase of 15.32% for the female students and 16.99% for the male students. The knowledge survey reveals a need to catch up on facts on the subject of boys' health. Despite evidence of an increase in knowledge of both sexes after sexual education instruction, there is a gender gap. Hence, a preventive check-up especially for boys should be established and offered. Issues such as the prevention of sexually transmitted diseases, options for vaccination against human papillomavirus, etc. should be actively addressed.

  14. Are Adolescent Girls More Depressive than Adolescent Boys in Turkey?

    Depression is a serious mental health problem that affects people of all ages, including children and adolescents. Studies showed that female gender is one of the risk factors may influence the development of depression in adolescents. However, some of the studies from Turkey suggested that gender does not lead to any significant difference in the youth depression level. Therefore, the presented study investigated whether girls differ from boys in respect of depression. T...

    A 12-year-old boy returned from a summer holiday in North Morocco with a slowly progressive erythematous, infiltrated plaque with a central crust on his right cheek. We diagnosed this as cutaneous leishmaniasis. Treatment for Leishmania major infection failed; subsequent PCR species typing revealed Leishmania infantum. This case shows the importance of recognition of parasitic skin diseases in travellers to the nearby subtropics and the value of leishmania species typing.

    Congenital absence of the portal vein (CAPV) is a malformation that is generally thought to be limited to females. We encountered an 11-year-old boy with this malformation. In 17 previously reported cases of CAPV, 2 were male. Three male patients, including our case, were Abernethy type Ib malformation. They had no associated liver tumour and two had no additional congenital abnormality. Conversely, 13 of the 15 female patients had congenital abnormalities and 6 had liver mass lesions. (orig.)

    In Canada, boys account for almost three quarters of suicides among those aged 15-24 years. However, non-fatal suicide-related behaviours also onset in youth but are more common in girls. Thus far, there has been little empirical investigation of what produces this gender paradox. This report summarizes two recently published studies in which ICES tackles the issues of the potential impacts of misclassification of suicide and of help-seeking behaviour.

    concept of liquid fuel based on molten fluorides. The proposal and organization of the project was based upon the activity of the national consortium TRANSMUTATION having been established in November 1996 by four leading institutions in nuclear research: Nuclear Research Institute Rez plc, Nuclear Physics Institute of Academy of Sciences, SKODA Nuclear Machinery plc and Faculty of Nuclear Sciences and Physical Engineering of the Czech Technical University in Prague to whom Technical University in Brno (specialized for a secondary circuit problems) has associated in the year 2000. The governmental authorities of the Czech Republic as well as the future utilities of the developed technology: Radwaste Repository Authority, CEZ a.s. (Czech Power Comp.), SKODA Works Company Nuclear Machinery Branch plc and some other bodies have been providing necessary funding. The substantial part of the project has been incorporated in suitable forms of international collaboration; the European Union's, so called, Framework Programs are supposed to be the most convenient ones, in particular. The individual parts of the project have been incorporated to the corresponding tasks (Work Packages) of the MOST (Molten Salt Technology) Project of the 5th Framework Program of the EC since November 2001 for the period of two years and then they have been prolonged for two more years. There is a convenient incorporation of the whole complex being proposed into the 6th Framework Program for the next three years (2006-2008) as a basis for a European participation in the Generation IV as well as other forms of a multinational co-operation, too. There will be a current status of the project being focused on an experimental verification of the selected technology, in a full scale at room temperature and in a small scale under conditions close to operational, described in the paper.

    Full Text Available Background The ages of onset of pubertal characteristics are influenced by genetic, geographic, dietary and socioeconomic factors; however, due to lack of country-specific norms, clinicians in Saudi Arabia use Western estimates as standards of reference for local children. Aims The aim of the Riyadh Puberty Study was to provide data on pubertal development to determine the average age of onset of pubertal characteristics among Saudi boys. Methods Cross-sectional study among male school children in Riyadh, Saudi Arabia, in 2006, 542 schoolboys, aged 6 to 16 years old, from diverse socioeconomic levels were selected into the sample using a cluster sample design. Tanner stages were ascertained during physical examination by pediatric endocrine consultants, and also trained pediatric residents and fellows. Results The mean age (standard deviation at Tanner Stages 2, 3, 4, and 5 for pubic hair development of Saudi boys was 11.4 (1.6, 13.3 (1.3, 14.4 (1.0 and 15.1 (0.8 years old, respectively. For gonadal development, the mean age (standard deviation at stages 2, 3, 4, and 5 were 11.4 (1.5, 13.3 (1.2, 14.3 (1.1 and 15.0 (0.9 years old, respectively. Conclusion The ages of onset of pubertal characteristics, based on gonadal development, among Saudi boys are comparable to those reported in Western populations.

    Targeted weight-bearing activities during the pre-pubertal years can improve cortical bone mass, structure and distribution, but less is known about the influence of habitual physical activity (PA) and fitness. This study examined the effects of contrasting habitual PA and fitness levels on cortical bone density, geometry and mass distribution in pre-pubertal children. Boys (n = 241) and girls (n = 245) aged 7-9 years had a pQCT scan to measure tibial mid-shaft total, cortical and medullary area, cortical thickness, density, polar strength strain index (SSIpolar) and the mass/density distribution through the bone cortex (radial distribution divided into endo-, mid- and pericortical regions) and around the centre of mass (polar distribution). Four contrasting PA and fitness groups (inactive-unfit, inactive-fit, active-unfit, active-fit) were generated based on daily step counts (pedometer, 7-days) and fitness levels (20-m shuttle test and vertical jump) for boys and girls separately. Active-fit boys had 7.3-7.7 % greater cortical area and thickness compared to inactive-unfit boys (P girls, but active-fit girls had 6.1 % (P girls, which was likely due to their 6.7 % (P active-fit girls. Higher levels of habitual PA-fitness were associated with small regional-specific gains in 66 % tibial cortical bone mass in pre-pubertal children, particularly boys.
