Sensorimotor rhythm (SMR) activity has been related to automaticity during skilled action execution. However, few studies have bridged the causal link between SMR activity and sports performance. This study investigated the effect of SMR neurofeedback training (SMR NFT) on golf putting performance. We hypothesized that preelite golfers would exhibit enhanced putting performance after SMR NFT. Sixteen preelite golfers were recruited and randomly assigned into either an SMR or a control group. Participants were asked to perform putting while electroencephalogram (EEG) was recorded, both before and after intervention. Our results showed that the SMR group performed more accurately when putting and exhibited greater SMR power than the control group after 8 intervention sessions. This study concludes that SMR NFT is effective for increasing SMR during action preparation and for enhancing golf putting performance. Moreover, greater SMR activity might be an EEG signature of improved attention processing, which induces superior putting performance.

Putting science on the agenda

CERN Multimedia

2012-01-01

The job of CERN Director-General comes with a lot of responsibility, and that’s particularly true today. We’re living through a period of unique circumstances for science. Positive indicators, such as a renewal of interest in physical sciences at the University level and unprecedented public interest in the LHC, are aligning with storm clouds in the form of a prolonged economic crisis that will put downward pressure on everyone’s budgets.   That means that science has to make its voice heard if it’s to preserve support, and if it wants to be in a position to play the role it must in navigating the major societal challenges of our time. For that reason, I have been a fairly rare sight at CERN of late. Last week, I was in Davos for the annual meeting of the World Economic Forum. It was my second time at Davos, and I used the opportunity to argue that science should be more closely linked to the political thread of the meeting. I think my argument was he...

The purpose of this clinical nurse specialist-led interprofessional quality improvement project was to reduce hospital-acquired pressure ulcers (HAPUs) using evidence-based practice. Hospital-acquired pressure ulcers (PUs) have been linked to morbidity, poor quality of life, and increasing costs. Pressure ulcer prevention and management remain a challenge for interprofessional teams in acute care settings. Hospital-acquired PU rate is a critical nursing quality indicator for healthcare organizations and ties directly with Mount Sinai Hospital's (MSH's) mission and vision, which mandates providing the highest quality care to patients and families. This quality improvement project, guided by the Donabedian model, was based on the Registered Nurses' Association of Ontario Best Practice Guideline Risk Assessment & Prevention of Pressure Ulcers. A working group was established to promote evidence-based practice for PU prevention. Initiatives such as documentation standardization, development of staff education and patient and family educational resources, initiation of a hospital-wide inventory for support surfaces, and procurement of equipment were implemented to improve PU prevention and management across the organization. An 80% decrease in HAPUs has been achieved since the implementation of best practices by the Best Practice Guideline Pressure Ulcer working group. The implementation of PU prevention strategies led to a reduction in HAPU rates. The working group will continue to work on building interprofessional awareness and collaboration in order to prevent HAPUs and promote an organizational culture that supports staff development, teamwork and communication. This quality improvement project is a successful example of an interprofessional clinical nurse specialist-led initiative that impacts patient/family and organization outcomes through the identification and implementation of evidence-based nursing practice.

Effects of competitive pressure on expert performance: underlying psychological, physiological, and kinematic mechanisms.

Although it is well established that performance is influenced by competitive pressure, our understanding of the mechanisms which underlie the pressure-performance relationship is limited. The current experiment examined mediators of the relationship between competitive pressure and motor skill performance of experts. Psychological, physiological, and kinematic responses to three levels of competitive pressure were measured in 50 expert golfers, during a golf putting task. Elevated competitive pressure increased putting accuracy, anxiety, effort, and heart rate, but decreased grip force. Quadratic effects of pressure were noted for self-reported conscious processing and impact velocity. Mediation analyses revealed that effort and heart rate partially mediated improved performance. The findings indicate that competitive pressure elicits effects on expert performance through both psychological and physiological pathways.

Carbon dioxide removal and tradeable put options at scale

Science.gov (United States)

Lockley, Andrew; Coffman, D.’Maris

2018-05-01

Options are derivative contracts that give the purchaser the right to buy (call options) or sell (put options) a given underlying asset at a particular price at a future date. The purchaser of a put option may exercise the right to sell the asset to the issuer at any point in the future before the expiration of the contract. These rights may be contracted directly between two parties (i.e. over-the-counter), or may be sold publicly on formal exchanges, such as the Chicago Board Options Exchange. If the latter, they are called tradeable put options (TPOs) because they can be bought and sold by third-parties via a secondary market. The World Bank has a Pilot Auction Facility for methane and carbon mediation which uses TPOs in carbon-relevant markets, giving producers (of e.g. forest restoration) a floor price for their product [1]. This enables long-term producer planning. We discuss the potentially broader use of these options contracts in carbon dioxide removal (CDR) markets generally and at scale. We conclude that they can, if priced correctly, encourage rapid investment both in CDR technology and in operational capacity. TPOs could do this without creating the same type of systemic risk associated with other instruments (e.g. long-dated futures). Nevertheless, the widespread use of such instruments potentially creates novel risks. These include the political risk of premature closure [2] (conventionally rendered as ‘counting your chickens before they are hatched’) and the economic risk of overpaying for carbon removal services. These instruments require careful structuring, and do not inoculate the CDR market against regulatory disruption, or political pressure. Accordingly, we note the potential for the development of TPO markets in CDR, but we urge caution in respect of identified risks.

Project risk management: A review of an institutional project life cycle

Directory of Open Access Journals (Sweden)

Wanjiru Gachie

2017-11-01

Full Text Available This article is a desktop analysis of project risk management involving a project management institutional restructuring. The pragmatic nature of this research allows for the literature review and the document analysis to be integrated and presented as both a descriptive and analytical research. The analysis demonstrates that the project committee did not proactively manage project risk. The restructuring was a change management project, entailing the implementation of many organisational changes, such as restructuring, lay-off of some part of the administrative workforce, adoption of new technology, provision of new approaches to well-established procedures, and implementation of new performance initiative, the process which should have been managed with an effective integrated risk strategy and plan. Analysis of the restructuring project risk management exhibits little evidence of a systematic (computer based or manual record that should have provided policies, procedures, and structures for managing risk. The article concludes that the restructuring risk process was inadequate and it could not have ensured a successful project. An analysis of the restructuring project risk monitoring and control exhibits a reactive rather than proactive application of risk management procedures. The analysis further indicates that the committee failed to make use of the various project risk management processes, standards, and guidelines. Based on the conclusions, the article recommends that project risk planning, strategy, control, and monitoring should be put in place for future institutional projects. The project management team should also put in place procedures for primary stakeholders engagements, identify and address their nature of interest and power in future risk management projects

The Qinshan CANDU Project Reactor Buildings (Units 1 and 2) have been successfully tested for the Pre-Service Proof Pressure and Integrated Leak Rate Tests. The Unit 1 tests took place from May 3 to May 9, 2002 and from May 22 to May 25, 2002, and the Unit 2 tests took place from January 21 to January 27, 2003. This paper discusses the significant steps taken at minimum cost on the Qinshan CANDU Project, which has resulted in a) very good leak rate (0.21%) for Unit 1 and excellent leak rate (0.130%) for Unit 2; b) continuous monitoring of the structural behaviour during the Proof Pressure Test, thus eliminating any repeat of the structural test due to lack of data; and c) significant schedule reduction achieved for these tests in Unit 2.

Full Text Available AIM OF THE STUDY The EDAPA Project (Education of self-measurement of blood pressure was conceived to train hypertensive patients in self blood pressure monitoring (SBPM and to survey their feedback, including patient’ assessment, by recording their related cardiovascular diseases (CVD risks factors and lifestyle habits. METHODS The project was conducted during the year 2006. Initially we met Grottaglie’s citizens and illustrated to participants the importance of SBPM at home in the overall management of hypertension, that might lead to a better control of BP and cardiovascular outcomes. After explaining the correct technique for SBPM, we distributed semiautomatic devices (OMRON M6 and asked the participants to fill in the Hypertension Questionnaire Form and to record their own blood pressure values in a diary. RESULTS Among almost 3,000 citizens interviewed, 370 (198 M, 172 F; mean age: 60 years agreed to take part in our study. They were hypertensive for almost 10 years, but waited 3 years before beginning therapy. They measured BP 4 times a month and, in the same sitting, 66% of them carried out only 1 measurement, 29% of them 2 measurements and only 2.5% carried out 3 measurements. Taking as reference BP value of 135/85 mmHg, we registered 28% of the population as normotensive and the remaining 72% as hypertensive. Among the hypertensives, 30% showed a good control, 55% showed a bad one and the remaining 15% was not aware of being hypertensive. Adding non-treated hypertensives to those treated but not controlled, we noticed that 70% of the participants was not properly controlled. Regarding risk factors, almost 64% showed hypercholesterolemia; 18% were smokers; 35% of males and 28% of females showed hyperglicemia and 63% of the latter had a waist line > 88 cm; 32% used to consume alcohol (46% males and 15% females; 26% had a metabolic syndrome; 13% was affected by vascular brain injuries, 30% by peripheral artheriopaty, 35% had heart

Over two centuries of economic growth have put undeniable pressure on the ecological systems that underpin human well-being. While it is agreed that these pressures are increasing, views divide on how they may be alleviated. Some suggest technological advances will automatically keep us from transgressing key environmental thresholds; others that policy reform can reconcile economic and ecological goals; while a third school argues that only a fundamental shift in societal values can keep human demands within the Earth's ecological limits. Here we use novel integrated analysis of the energy-water-food nexus, rural land use (including biodiversity), material flows and climate change to explore whether mounting ecological pressures in Australia can be reversed, while the population grows and living standards improve. We show that, in the right circumstances, economic and environmental outcomes can be decoupled. Although economic growth is strong across all scenarios, environmental performance varies widely: pressures are projected to more than double, stabilize or fall markedly by 2050. However, we find no evidence that decoupling will occur automatically. Nor do we find that a shift in societal values is required. Rather, extensions of current policies that mobilize technology and incentivize reduced pressure account for the majority of differences in environmental performance. Our results show that Australia can make great progress towards sustainable prosperity, if it chooses to do so.

For the purpose of reducing greenhouse effect gas emissions, a feasibility study was conducted on the energy conservation at Panzhihua Iron and Steel Company in Sichuan Province, China. In this project, the pressure energy of blast furnace is to be recovered in the form of electric power by installing the blast furnace top pressure recovery turbine (TRT). In the project, the pressure-reducing valve was removed, and the dry dust collector/dry TRT were installed to make the scale of electric power production largest. A model of TRT was installed at No. 4 blast furnace and is now in operation. In this project, TRTs are to be installed at Nos. 1, 2 and 3 blast furnaces. As a result of the study, the investment totaled 5.46 billion yen. The capacity of power generation by TRT is 16,890 kW, and the generated output is 137,822 MWh/y. Moreover, the amount of energy conservation is 36,467 toe/y, and the reduction amount of greenhouse effect gas emissions is 112,830 CO2-ton/y. The term of investment recovery is 8.3 years. The effect of reduction in greenhouse effect gas emissions is 20.66 CO2-ton/y/million yen. (NEDO)

2012-06-01

We observed in our institute a 13.6% incidence of prolonged surgery (>4 hours) induced facial pressure ulcers that required prone positioning. Causes identified included: (1) customized silicon face pillows used were not suited for every patient; (2) our institute lacked a standard operating procedure for prone positioning; (3) our institute lacked a postoperative evaluation and audit procedure for facial pressure ulcers. We designed a strategy to reduce post-prolonged surgery facial pressure ulcer incidence requiring prone positioning by 50% (i.e., from 13.6% to 6.8%). We implemented the following: (1) Created a new water pillow to relieve facial pressure; (2) Implemented continuing education pressure ulcer prevention and evaluation; (3) Established protocols on standard care for prone-position patients and proper facial pressure ulcer identification; (4) Established a face pressure ulcers accident reporting mechanism; and (5) Established an audit mechanism facial pressure ulcer cases. After implementing the resolution measures, 116 patients underwent prolonged surgery in a prone position (mean operating time: 298 mins). None suffered from facial pressure ulcers. The measures effectively reduced the incidence of facial pressure ulcers from 13.6% to 0.0%. The project used a water pillow to relieve facial pressure and educated staff to recognize and evaluate pressure ulcers. These measures were demonstrated effective in reducing the incidence of facial pressure ulcers caused by prolonged prone positioning.

Valuing put options on single stock futures: Does the put-call parity relationship hold in the South African derivatives market?

2014-12-01

Full Text Available This study attempts to determine whether mispricing of options on single stock futures is present in the South African derivatives market. The valuation of options on single stock futures is considered through the put-call parity relationship. The theoretical fair values obtained, are compared to the actual market values over a period of three years, that is, from 2009 to 2011. Only put options are considered in this research.The results show that arbitrage put option opportunities do present themselves for the chosen shares. The actual put options were found to be underpriced in 5 out of 6 (83% of the cases considered over the evaluation periods chosen. The mispricing was significant for both the BHP Billiton options with 100% and in the case of Sasol options (66% of the time. Whether profitable arbitrage opportunities is possible, will depend on the magnitude of the mispricing and the transaction fees payable. Further, more extensive research may help identify tendencies which may be of use for the formulation of arbitrage strategies

Income-based projections of water footprint of food consumption in Uzbekistan

Djanibekov, Nodir; Frohberg, Klaus; Djanibekov, Utkur

2013-11-01

Assessing future water requirements for feeding the growing population of Central Asia can improve understanding of the projected water supply scenarios in the region. Future water requirements will be partially determined by the dietary habits of the populations, and are thus responsive to significant variation of income levels. Using Uzbekistan as an example, this study projects the water footprints of income driven changes on the population's diet in Central Asia. To reveal the influence of large income changes on dietary habits a Normalized Quadratic-Quadratic Expenditure System was calibrated and applied to data from 2009. The national water footprints of food consumption in Uzbekistan were projected until 2034 by applying the parameterized demand system to estimate the respective water footprint values. The results showed that for Uzbekistan the projected increase in the food consumption water footprint would be primarily linked to income growth rather than population growth. Due to the high water footprint of common food products, the composition of the population's diet, and responsiveness to income, economic growth is expected to put greater pressure on water resources in Uzbekistan unless proper measures are undertaken.

Climate-smart conservation: putting adaption principles into practice

Science.gov (United States)

Stein, Bruce A.; Glick, Patty; Edelson, Naomi; Staudt, Amanda

2014-01-01

Climate change already is having significant impacts on the nation’s species and ecosystems, and these effects are projected to increase considerably over time. As a result, climate change is now a primary lens through which conservation and natural resource management must be viewed. How should we prepare for and respond to the impacts of climate change on wildlife and their habitats? What should we be doing differently in light of these climatic shifts, and what actions continue to make sense? Climate-Smart Conservation: Putting Adaptation Principles into Practice offers guidance for designing and carrying out conservation in the face of a rapidly changing climate. Addressing the growing threats brought about or accentuated by rapid climate change requires a fundamental shift in the practice of natural resource management and conservation. Traditionally, conservationists have focused their efforts on protecting and managing systems to maintain their current state, or to restore degraded systems back to a historical state regarded as more desirable. Conservation planners and practitioners will need to adopt forward-looking goals and implement strategies specifically designed to prepare for and adjust to current and future climatic changes, and the associated impacts on natural systems and human communities—an emerging discipline known as climate change adaptation. The field of climate change adaptation is still in its infancy. Although there is increasing attention focused on the subject, much of the guidance developed to date has been general in nature, concentrating on high-level principles rather than specific actions. It is against this backdrop that this guide was prepared as a means for helping put adaptation principles into practice, and for moving adaptation from planning to action.

Medical devices have been identified as an extrinsic risk factor for development of pressure injuries, with as many as 30% to 70% of medical device-related pressure injuries resulting from respiratory equipment. This article describes a quality improvement project undertaken to reduce the occurrence of respiratory device-related pressure injuries in a critically care unit. Multiple actions were implemented to achieve this goal. Respiratory therapists were trained to document occurrences on a daily basis, and apparent cause analyses were conducted on each occurrence. An interdisciplinary team conducted biweekly rounds on patients with respiratory devices and consulted other professionals as indicated. Nurses and respiratory therapists attended an evidence-based, collaborative, educational offering and completed a measure of team functioning before the program and at the end of the study period. The occurrence rates of respiratory device-related pressure injuries were reduced over the project period, and these changes were sustained over the subsequent 12 months.

Pressure vessel rupture within a chamber: the pressure history on the chamber wall

International Nuclear Information System (INIS)

Baum, M.R.

1989-04-01

Generally there is a large number of pressure vessels containing high pressure gas on power stations and chemical plant. In many instances, particularly on power plant, these vessels are within the main building. If a pressure vessel were to fail, the surrounding structures would be exposed to blast loads and the forces resulting from jets of fluid issuing from the breached vessel. In the case where the vessel is in a relatively closed chamber there would also be a general overpressurisation of the chamber. At the design stage it is therefore essential to demonstrate that the plant could be safely shut down in the event of a pressure vessel failure, that is, it must be shown that the chamber will not collapse thus putting the building at risk or hazarding equipment essential for a safe shut down. Such an assessment requires the loads applied to the chamber walls, roof, etc. to be known. (author)

Unhealthy Pressure: How Physician Pay Demands Put the Squeeze on Provincial Health-Care Budgets

Directory of Open Access Journals (Sweden)

Hugh M. Grant

2013-07-01

were successful in holding back the growth in doctors’ fees, to the point where physicians saw their purchasing power shrink. If Canadians are now questioning where the priorities of doctors truly lie — whether its preserving health care or enriching themselves — the provinces can only gain more leverage in future negotiations with doctors. Physicians in the Canadian health-care system are entrusted with a special and protected role, and it behooves medical associations to bear in mind their additional responsibility to promote public health-care objectives. The current collective bargaining model has resulted in provinces pressured into buying healthcare peace by agreeing to continually ratchet up doctors’ pay. It is difficult to see how that can continue. It is time that doctors began working with policy-makers on a new model, one that puts less emphasis on profiting doctors, and more emphasis on promoting a sustainable health-care system for everyone.

For the first time after political and economical changes in Germany a hydrothermal site was put into operation in December 1994. Due to prevailing conditions extraordinary in Central Europe (reservoir temperature 99{degrees}C; 220 g/l salinity) the project Neustadt-Glewe is supported by a comprehensive research program. The wells concerned (a doublet with an internal distance of 1.400 m) open the porous sandstone aquifer with an average thickness of about 53 m in a depth of 2.240m. One point of interest was the pressure and temperature behavior over a period of 10 years considering the fluid viscosity changes due to variable injection temperature. For means of reservoir simulation and prognosing the injection behavior and simulator code TOUGH2 was used.

Metal extrusion using hydrostatic pressures

International Nuclear Information System (INIS)

Sauve, Ch.

1965-01-01

The main problems connected with the deformation of metals due to extrusion are described. A method is put forward for calculating the rational rate of percentage deformation in the case of bar extrusion using a cylindrical container; reference is made to previous work on extrusion using a hydrostatic pressure with or without back-pressure. An extrusion process is described using hydrostatic pressure, without back-pressure, and using the lubricant for transmitting the thrust. This process has been used for eight years by the C.E.A. for the extrusion of a very wide range of metals, from beryllium to uranium and including steels; it leads to excellent surface textures. A very fine crystallization can be obtained on extruded products when the rate of extrusion is very low. There appears to be nothing against the use of high extrusion rates using this method.

Effects of high hydrostatic pressure were investigated on vegetable seeds in the GPa range to examine the potentialities of breed improvement by high-pressure processing. Specimens of several seeds of broccoli (Brassica oleracea var. italica), Turnip leaf (Brassica rapa var. perviridis) and Potherb Mustard (Brassica rapa var. nipposinica) were put in a teflon capsule with liquid high pressure medium, fluorinate, and inserted into a pyrophillite cube. By using a cubic anvil press a hydrostatic pressure of 5.5 GP a was applied to these seeds for 15 minutes. After being brought back to ambient pressure, they were seeded on humid soil in a plant pot. Many of these vegetable seeds began to germinate within 6 days after seeded.

Biophysical investigation of type A PutAs reveals a conserved core oligomeric structure

Many enzymes form homooligomers, yet the functional significance of self-association is seldom obvious. Herein, we examine the connection between oligomerization and catalytic function for proline utilization A (PutA) enzymes. PutAs are bifunctional enzymes that catalyze both reactions of proline catabolism. Type A PutAs are the smallest members of the family, possessing a minimal domain architecture consisting of N-terminal proline dehydrogenase and C-terminal l-glutamate-γ-semialdehyde dehydrogenase modules. Type A PutAs form domain-swapped dimers, and in one case (Bradyrhizobium japonicum PutA), two of the dimers assemble into a ring-shaped tetramer. Whereas the dimer has a clear role in substrate channeling, the functional significance of the tetramer is unknown. To address this question, we performed structural studies of four-type A PutAs from two clades of the PutA tree. The crystal structure of Bdellovibrio bacteriovorus PutA covalently inactivated by N-propargylglycine revealed a fold and substrate-channeling tunnel similar to other PutAs. Small-angle X-ray scattering (SAXS) and analytical ultracentrifugation indicated that Bdellovibrio PutA is dimeric in solution, in contrast to the prediction from crystal packing of a stable tetrameric assembly. SAXS studies of two other type A PutAs from separate clades also suggested that the dimer predominates in solution. To assess whether the tetramer of B. japonicum PutA is necessary for catalytic function, a hot spot disruption mutant that cleanly produces dimeric protein was generated. The dimeric variant exhibited kinetic parameters similar to the wild-type enzyme. These results implicate the domain-swapped dimer as the core structural and functional unit of type A PutAs.

Chinese electric power industry has adopted Build-Operate-Transfer (BOT) approach in a number of projects to alleviate the pressure of sole state-owned investment. The Chinese government has taken enormous efforts to create an environment to facilitate the application of BOT approach in electric power projects. Moreover, the growing attention on the sustainability issues puts the traditional major source of electricity - thermal power project under more strict scrutiny. As a result, various renewable energy projects, particularly the wind power projects have involved private sector funds. Both thermal power and wind power projects via BOT approach have met with a varying degree of success. Therefore, it is imperative to understand the factors contributing towards the success of both types of BOT power projects. Using an extensive literature survey, this paper identifies 31 success factors under 5 categories for Chinese BOT electric power projects. This is followed by a questionnaire survey to exam relative significance of these factors. The results reveal the different levels of significance of success factors for BOT thermal power projects versus wind power projects. Finally, survey results were analyzed to explore the underlying construction and distributions among the identified success factors. This study provides a valuable reference for all involved parties that are interested in developing BOT electric power projects in China. (author)

Russian neo-revisionist strategy and the Eurasian Project

Directory of Open Access Journals (Sweden)

Ruslan Dzarasov

2017-03-01

Full Text Available The article is focused on the real meaning of the Eurasian Integration Project for East–West relations. The author departs from Sakwa’s treatment of Russian strategy as neo-revisionist. It does not aspire to change the current world order while trying to make the West observe its national interests within the existing framework. This perspective is treated in the article from the standpoint of world-systems analysis. The Eurasian Project is understood as a reaction of the Russian state to the failure of the neoliberal attempt to integrate into the world economy and the international security system. The two great trade mega-unions—the Trans-Pacific Partnership (TPP and the Trans-Atlantic Partnership—are seen as geoeconomic bolt clamps, which put Russia under enormous pressure. The Russian strategy in the Ukrainian and Syrian crises is designed to find the way out of strategic isolation. The Eurasian Union is expected by the Russian ruling elite to be an important tool to forestall the isolation of the country and secure her economic, military and international security.

Putting rural energy access projects into perspective: What lessons are relevant?

International Nuclear Information System (INIS)

Vleuten, Frank van der; Stam, Nienke; Plas, Robert-Jan van der

2013-01-01

As the Secretary General of the United Nations and the president of the World Bank are calling upon countries to commit themselves to universal access to modern energy services by 2030, and international players such as the International Energy Agency, the EU, and ESMAP are building scenarios how to accomplish this, this article demonstrates the non-linear dynamics of scaling up rural energy access, drawing among others from over 70 energy access projects implemented by the EASE network of national energy and development NGOs in eight countries and on experiences combining microfinance and (clean) energy access. The article shows that scaling up rural energy access demands careful tuning of support to the business models of rural entrepreneurs, in which development finance has only a limited role to play. The article argues for market development approaches that take a programmatic approach, change their intervention model as the market matures, and build on smart use of the limited sector capacity. The ultimate challenge is how to down-tune ambitions and spending power of the development community to match the absorption capacity of rural markets and the reality of entrepreneurs on the ground. - Highlights: • Practitioner's experiences and lessons, based on over 70 implemented projects. • Relevant for “Sustainable Energy for All” high-level initiative. • Match high international ambitions with low capacity of rural energy markets

Enhancing the control of force in putting by video game training.

Fery, Y A; Ponserre, S

Even if golf video games provide no proprioceptive afferences on actual putting movement, they may give sufficient substitutive visual cues to enhance force control in this skill. It was hypothesized that this usefulness requires, however, two conditions: the video game must provide reliable demonstrations of actual putts, and the user must want to use the game to make progress in actual putting. Accordingly, a video game was selected on the basis of its fidelity to the real-world game. It allowed two different methods of adjusting the virtual player's putting force in order to hole a putt: an analogue method that consisted of focusing on the virtual player's movement and a symbolic method that consisted of focusing on the movement of a gauge on a scale representing the virtual player's putting force. The participants had to use one of these methods with either the intention of making progress in actual putting or in a second condition to simply enjoy the game. Results showed a positive transfer of video playing to actual putting skill for the learning group and also, to a lesser degree, for the enjoyment group; but only when they used the symbolic method. Results are discussed in the context of how vision may convey force cues in sports video games.

The scholars increasingly pay at ention to the internal rules in knowledge development and innovation of construction engineering management,as wel as the framework for engineering management body of knowledge. Considering the one-of-a-kind characteristic of construction project s and highly dependence from projects on management knowledge and its innovation,this paper analyzed the knowledge body of engineering management and its development dimension ,such as thinking and knowledge structure dimensions. The engineering management knowledge innovation model and structural model were put forward. The paper reviewed and proposed the engineering management knowledge system framework under engineering thinking mode,including the basic knowledge system framework which is used in engineering management research ,and a framework for body of knowledge which is applicable for engineering management practice. Based on a brief analysis of engineering management practice,this paper analyzed the development progres of engineering management from engineering thinking to ethical thinking and philosophical thinking. A dynamic model formed from the modern engineering management theory was put forward. The construction of projects are divided into two stages:an investment decision-making stage, and project implementation stage. According to the fact that project owners obtain the project products by transaction,the management during project implementation stage are divided into two aspects:project transaction management for the owner, and construction project management for the contractor. Thus, the three theoretical modules of modern engineering management were established:project investment decision-making management theory,engineering transaction management theory, and engineering project management theory. This paper further analyzed the content and basic theoretical issues of each theoretical module.

Managing Innovation under Time Pressure: A Practical Perspective

Directory of Open Access Journals (Sweden)

Blair Winsor

2012-08-01

Full Text Available This article examines the effects of time pressure on innovation. Does time pressure stimulate or eliminate innovation or, in other words, should managers increase or reduce time pressures if they are trying to enhance innovation in their firms? Unfortunately, current research on the subject is ambivalent. To provide some clarity, this innovation management dilemma was examined in a fast-growing, medium-sized communication and IT consultancy (“First”, which claimed to be “highly innovative”. Detailed data on five projects was collected over an 18-month period using practice-based methods. Each project team was followed in real time via observation and interviews. The data was then analyzed by dividing project work into three phases: i negotiating the project particulars with the client; ii conducting project work; and iii project evaluation. This detailed analysis revealed how time pressures eliminated innovation in First’s client-based project work and suggested three implications for the management of innovation. Firstly, managers should try to avoid imposing excessive time pressures on their project teams. Secondly, they should ensure that there is space between projects to enable reflection. Thirdly, managers should ensure that project debriefs occur and that they cover potential innovations.

How effective project management will add value to your uranium project

International Nuclear Information System (INIS)

Bradford, R.; Titley, M.

2014-01-01

Up until the recent Fukushima incident in March 2011 project activity in the uranium sector was driven by high uranium prices and merger and acquisition corporate activity. Soon after the incident, project development in the uranium sector collapsed and capital slowly dried up as Uranium prices dropped. New projects were put on hold, significantly reducing growth in the small to medium capital markets. Existing brownfield growth plans were halted as corporate strategies focused on improving the efficiency of existing assets. Recent positive sentiment supported by positive commentary in the uranium market, driven by an improved understanding of the supply and demand fundamentals and the restart of Japan’s nuclear reactors, has seen renewed corporate merger and acquisition activity. Developers are again taking an interest in new uranium project development.

Neural set point for the control of arterial pressure: role of the nucleus tractus solitarius

Directory of Open Access Journals (Sweden)

Valentinuzzi Max E

2010-01-01

Full Text Available Abstract Background Physiological experiments have shown that the mean arterial blood pressure (MAP can not be regulated after chemo and cardiopulmonary receptor denervation. Neuro-physiological information suggests that the nucleus tractus solitarius (NTS is the only structure that receives information from its rostral neural nuclei and from the cardiovascular receptors and projects to nuclei that regulate the circulatory variables. Methods From a control theory perspective, to answer if the cardiovascular regulation has a set point, we should find out whether in the cardiovascular control there is something equivalent to a comparator evaluating the error signal (between the rostral projections to the NTS and the feedback inputs. The NTS would function as a comparator if: a its lesion suppresses cardiovascular regulation; b the negative feedback loop still responds normally to perturbations (such as mechanical or electrical after cutting the rostral afferent fibers to the NTS; c perturbation of rostral neural structures (RNS to the NTS modifies the set point without changing the dynamics of the elicited response; and d cardiovascular responses to perturbations on neural structures within the negative feedback loop compensate for much faster than perturbations on the NTS rostral structures. Results From the control theory framework, experimental evidence found currently in the literature plus experimental results from our group was put together showing that the above-mentioned conditions (to show that the NTS functions as a comparator are satisfied. Conclusions Physiological experiments suggest that long-term blood pressure is regulated by the nervous system. The NTS functions as a comparator (evaluating the error signal between its RNS and the cardiovascular receptor afferents and projects to nuclei that regulate the circulatory variables. The mean arterial pressure (MAP is regulated by the feedback of chemo and cardiopulmonary receptors and

An arbitrarily arranged projection moiré system is presented for three-dimensional shape measurement. We develop a model for projection moiré system and derive a universal formula expressing the relation between height and phase variation before and after we put the object on the reference plane. With so many system parameters involved, a system calibration technique is needed. In this work, we provide a robust and accurate calibration method for an arbitrarily arranged projection moiré system. The system no longer puts restrictions on the configuration of the optical setup. Real experiments have been conducted to verify the validity of this method.

Putting politics first.

Science.gov (United States)

Hacker, Jacob S

2008-01-01

The greatest lesson of the failure of comprehensive health reform in the early 1990s is that politics comes first. Even the best-laid policy plans are worthless if they lack the political support to pass. Putting politics first means avoiding the overarching mistake of the Clinton reformers: envisioning a grand policy compromise rather than hammering out a real political compromise. It also means addressing the inevitable fears of those who believe that they are well protected by our eroding employment-based system. And it means formulating political strategies that are premised on the contemporary realities of the hyperpolarized U.S. political environment, rather than wistfully recalled images of the bipartisan politics of old.

Kennedy, Kriss J.; Toup, Larry; Gill, Tracy; Tri, Terry; Howe, Scott; Smitherman, David

2011-01-01

This paper gives an overview of the National Aeronautics and Space Administration (NASA) led multi-center Habitat Demonstration Unit (HDU) project leadership and management strategies being used by the NASA HDU team for a rapid prototyping project. The HDU project team constructed and tested an analog prototype lunar surface habitat/laboratory called the Pressurized Excursion Module (PEM) during 2010. The prototype unit subsystems were integrated in a short amount of time, utilizing a tiger team rapid prototyping approach that brought together over 20 habitation-related technologies and innovations from a variety of NASA centers. This paper describes the leadership and management strategies as well as lessons learned pertaining to leading and managing a multi-center diverse team in a rapid prototype environment. The PEM configuration went from a paper design to an operational surface habitat demonstration unit in less than 12 months. The HDU project is part of the strategic plan from the Exploration Systems Mission Directorate (ESMD) Directorate Integration Office (DIO) and the Exploration Mission Systems Office (EMSO) to test destination elements in analog environments. The 2011 HDU-Deep Space Habitat (DSH) configuration will build upon the PEM work, and emphasize validity of crew operations (remote working and living), EVA operations, mission operations, logistics operations, and science operations that might be required in a deep space context for Near Earth Object (NEO) exploration mission architectures. The 2011 HDU-DSH will be field-tested during the 2011 Desert Research and Technologies Studies (DRaTS) field tests. The HDU project is a "technology-pull" project that integrates technologies and innovations from multiple NASA centers. This project will repurpose the HDU 2010 demo unit that was field tested in the 2010 DRaTS, adding habitation functionality to the prototype unit. This paper will describe the strategy of establishing a multi-center project

Diffractive Photon Dissociation in a High Pressure Hydrogen Time Projection Chamber

We have performed an experiment at the Tagged Photon Facility of Fermilab to study the diffraction dissociation of high energy photons on hydrogen y + p -+ x + p in the region 0.02 < $\\mid t \\mid$ < 0.1 $(GeV/c)^2$, $M_x$ $^2/s$ < 0.1. In this process, incident photons whose energies range from 70 to 140 GeV transform coherently to massive hadronic states in the mass range M < 5 GeV/c 2 • x We measure the inclusive differential cross section$\\frac{d^20}{dt dM_x ^2}$) The behavior of this cross section, especially when compared to the corresponding cross sections for the diffraction dissociation of incident hadrons (pions, kaons, and protons), reveals some fundamental characteristics of photon hadronic interactions. We use the Recoil Technique to determine the missing mass, $M_x$, and the square of the 4-momentum transfer, t. The recoil detector, TREAD, is a cylindrical time projection chamber filled with high pressure hydrogen gas which serves both as the target and as the drift medium for the ionization track created by recoil protons. The ionization drifts up to 75 cm in a high axial electric field. Concentric sense wires mounted on endplates sample different parts of the track, yielding the polar angle of the recoil. The energy of the recoil is determined by stopping the proton in scintillation counters located inside the high pressure vessel....

Genetic data indicate that the PutA protein is both put repressor and a respiratory chain-linked dehydrogenase. We report a redesigned purification procedure as well as the physical characteristics and biological activities of the PutA protein purified from E. coli. The purified protein was homogeneous as determined by electrophoresis performed under denaturing and nondenaturing conditions. Its N-terminal sequence corresponded to that predicted by the DNA sequence. We showed copurification of proline and delta 1-pyrroline-5-carboxylate dehydrogenase activities. Purified PutA protein bound put DNA in vitro in an electrophoretic band-shift assay and it could be reconstituted to inverted membrane vesicles, yielding proline dehydrogenase activity. The Stokes radius and Svedberg coefficient of the protein were determined to be 7.1 nm and 9.9 S, respectively. These hydrodynamic data revealed that the protein in our preparation was dimeric with a molecular mass of 293 kDa and that it had an irregular shape indicated by the friction factor (f/f0) of 1.6.

Prevention of pressure ulcers is one of the greatest healthcare challenges in terms of reducing patient harm. The literature shows that although numerous reports and policy documents have been published, pressure ulcer prevention remains an ongoing challenge. A number of innovations have been published offering practising nurses and managers ideas for raising awareness of skin care and preventing pressure ulcers. The majority of these have focused on patients in hospital settings with very little in the literature related to care-home and community initiatives. This article reports on an innovative approach to education for pressure ulcer prevention through collaboration between patients, carers and health and social care professionals.

Putting Portugal on the Map

Directory of Open Access Journals (Sweden)

João Ferrão

2010-01-01

Full Text Available This paper argues the need to “put Portugal on the map” in a double sense: in a prospective way, in order to place the country on the required map(s, something which entails strategic vision and capacity for action; and in an analytical way – to enable us to understand Portugal from the map(s it is part of, which presupposes a capacity to analyse and understand the current state of affairs. By drawing inspiration from the polymorphic vision on the spatialities of contemporary societies and economies defended by Jessop, Brenner and Jones (2008, we propose the creation of a unifying reference framework to “put Portugal on the map”, using a combination of five elements: territory as a geographic location; territory as a unit of reference of the nation-state; places; geographic scales; and networks. The polymorphic nature of the spatialities that characterize, or should characterize, Portugal’s place in the world reflects several, and even contradictory, ethical values, interests, preferences, and options. Accordingly, the supported polymorphic spatialities ought to stir up controversy based on knowledge and arguments that are solid from a theoretical and empirical stance, and should make explicit the objectives and values they are based on.

Based on the elastoplastic fracture mechanics, this paper established the expression formulas of limit buckling pressure P u on the ligament of axial and circumferential surface cracks and the initial pressure for the through cracks P c . A new Leak Before Break (LBB) assessment criterion was put forward to predict the failure mode of pressure pipes, i.e., when P u is less than P c , the pipe will leak; when P u is equal to or larger than P c , the pipe will break, which is verified by the test data reported in literatures.

Steady Increase In Prices For Oral Anticancer Drugs After Market Launch Suggests A Lack Of Competitive Pressure.

Science.gov (United States)

Bennette, Caroline S; Richards, Catherine; Sullivan, Sean D; Ramsey, Scott D

2016-05-01

The cost of treating cancer has risen to unprecedented heights, putting tremendous financial pressure on patients, payers, and society. Previous studies have documented the rising prices of cancer drugs at launch, but less critical attention has been paid to the cost of these drugs after launch. We used pharmacy claims for commercially insured individuals to examine trends in postlaunch prices over time for orally administered anticancer drugs recently approved by the Food and Drug Administration (FDA). In the period 2007-13, inflation-adjusted per patient monthly drug prices increased 5 percent each year. Certain market changes also played a role, with prices rising an additional 10 percent with each supplemental indication approved by the FDA and declining 2 percent with the FDA's approval of a competitor drug. Our findings suggest that there is currently little competitive pressure in the oral anticancer drug market. Policy makers who wish to reduce the costs of anticancer drugs should consider implementing policies that affect prices not only at launch but also later.

We find the explicit value of perpetual American put options in the constant elasticity of variance model using the concept of smooth fit. We show that the price is increasing in the volatility and convex in the underlying stock price. Moreover, as the model converges to the standard Black and Scholes model, the value of the put is shown to approach the `correct' limit.

EPR (European Pressurized water Reactor) The advanced nuclear reactor

International Nuclear Information System (INIS)

2004-01-01

Nuclear energy, which provides a steady supply of electricity at low cost, has its rightful place in the energy mix of the 21. century, which puts the emphasis on sustainable development. The EPR is the only 3. generation reactor under construction today. It is an evolutionary reactor that represents a new generation of pressurized water reactors with no break in the technology used for the most recent models. The EPR was developed by Framatome and Siemens, whose nuclear activities were combined in January 2001 to form Framatome ANP, a subsidiary of AREVA and Siemens. EDF and the major German electricity companies played an active part in the project. The safety authorities of the two countries joined forces to bring their respective safety standards into line and draw up joint design rules for the new reactor. The project had three objectives: meet the requirements of European utilities, comply with the safety standards laid down by the French safety authority for future pressurized water reactors, in concert with its German counterpart, and make nuclear energy even more competitive than energy generated using fossil fuels. The EPR can guarantee a safe, inexpensive electricity supply, without adding to the greenhouse effect. It meets the requirements of the safety authorities and lives up to the expectations of electricity utilities. This document presents the main characteristics of the EPR, and in particular the additional measures to prevent the occurrence of events likely to damage the core, the leak-tight containment, the measures to reduce the exposure of operating and maintenance personnel, the solutions for an even greater protection of the environment. The foreseen development of the EPR in France and abroad (Finland, China, the United States) is summarized

Tourism's collapse puts Gambian women at risk.

Science.gov (United States)

Coker, M S

1995-06-01

Despite efforts of the Gambian government, which established a ministry in 1981 that would tackle gender issues, improve women's health, and promote empowerment, women are underrepresented in government and business, and 84% are illiterate. Child mortality is among the highest in Africa; 134 children per 1000 die before their fifth birthday. In the mid-1980s austerity measures adopted by the World Bank and IMF left the ministry without funds. Rice and vegetable production, the main source of income for women, fell in the 1990s. In 1994, paddy production dropped 23% from the previous year; this was due to a lack of technical and financial assistance. The collapse of tourism with Capt. Yahya Jammeh's seizure of power has put prostitutes catering to tourists out of work, but women who have lost jobs in the hotel industry may be pushed into local prostitution to survive. The impact of this on the HIV/AIDS epidemic is unclear. Although Gambia is one of the world's most aid-dependent countries (more than a quarter of the GNP before the coup), corruption and mismanagement in the nongovernmental sector is widespread. The director of the Women in Development Programme, a $15m World Bank project, was forced to resign over allegations of fraud. The political process sidelines women; only village chiefs, who are traditionally men, are allowed to vote when new heads are elected.

Advancing a smart air cushion system for preventing pressure ulcers using projection Moiré for large deformation measurements

Cheng, Sheng-Lin; Tsai, Tsung-Heng; Lee, Carina Jean-Tien; Hsu, Yu-Hsiang; Lee, Chih-Kung

A pressure ulcer is one of the most important concerns for wheelchair bound patients with spinal cord injuries. A pressure ulcer is a localized injury near the buttocks that bear ischial tuberosity oppression over a long period of time. Due to elevated compression to blood vessels, the surrounding tissues suffer from a lack of oxygen and nutrition. The ulcers eventually lead to skin damage followed by tissue necrosis. The current medical strategy is to minimize the occurrence of pressure ulcers by regularly helping patients change their posture. However, these methods do not always work effectively or well. As a solution to fundamentally prevent pressure ulcers, a smart air cushion system was developed to detect and control pressure actively. The air cushion works by automatically adjusting a patient's sitting posture to effectively relieve the buttock pressure. To analyze the correlation between the dynamic pressure profiles of an air cell with a patient's weight, a projection Moiré system was adopted to measure the deformation of an air cell and its associated stress distribution. Combining a full-field deformation imaging with air pressure measured within an air cell, the patient's weight and the stress distribution can be simultaneously obtained. By integrating a full-field optical metrology with a time varying pressure sensor output coupled with different active air control algorithms for various designs, we can tailor the ratio of the air cells. Our preliminary data suggests that this newly developed smart air cushion has the potential to selectively reduce localized compression on the tissues at the buttocks. Furthermore, it can take a patient's weight which is an additional benefit so that medical personnel can reference it to prescribe the correct drug dosages.

Moskaliuk, Johannes; Bertram, Johanna; Cress, Ulrike

2013-01-01

Virtual training environments are used when training in reality is challenging because of the high costs, danger, time or effort involved. In this paper we argue for a theory-driven development of such environments, with the aim of connecting theory to practice and ensuring that the training provided fits the needs of the trained persons and their organisations. As an example, we describe the development of VirtualPolice (ViPOL), a training environment for police officers in a federal state of Germany. We provided the theoretical foundation for ViPOL concerning the feeling of being present, social context, learning motivation and perspective-taking. We developed a framework to put theory into practice. To evaluate our framework we interviewed the stakeholders of ViPOL and surveyed current challenges and limitations of virtual training. The results led to a review of a theory-into-practice framework which is presented in the conclusion. Feeling of presence, social context, learning motivation and perspective-taking are relevant for training in virtual environments. The theory-into-practice framework presented here supports developers and trainers in implementing virtual training tools. The framework was validated with an interview study of stakeholders of a virtual training project. We identified limitations, opportunities and challenges.

This final technical progress report describes work conducted by Membrane Technology and Research, Inc. (MTR) for the Department of Energy (DOE NETL) on development of low-pressure membrane contactors for carbon dioxide (CO₂) capture from power plant flue gas (award number DE-FE0007553). The work was conducted from October 1, 2011 through September 30, 2014. The overall goal of this three-year project was to build and operate a prototype 500 m² low-pressure sweep membrane module specifically designed to separate CO₂ from coal-fired power plant flue gas. MTR was assisted in this project by a research group at the University of Toledo, which contributed to the computational fluid dynamics (CFD) analysis of module design and process simulation. This report details the work conducted to develop a new type of membrane contactor specifically designed for the high-gas-flow, low-pressure, countercurrent sweep operation required for affordable membrane-based CO₂ capture at coal power plants. Work for this project included module development and testing, design and assembly of a large membrane module test unit at MTR, CFD comparative analysis of cross-flow, countercurrent, and novel partial-countercurrent sweep membrane module designs, CFD analysis of membrane spacers, design and fabrication of a 500 m² membrane module skid for field tests, a detailed performance and cost analysis of the MTR CO₂ capture process with low-pressure sweep modules, and a process design analysis of a membrane-hybrid separation process for CO₂ removal from coal-fired flue gas. Key results for each major task are discussed in the report.

2017-12-01

To meet the needs of industries using high pressure technologies, in traceable, reliable and accurate pressure measurements, a joint research project of the five national metrology institutes and the university was carried out within the European Metrology Research Programme. In particular, finite element methods were established for stress-strain analysis of elastic and nonlinear elastic-plastic deformation, as well as of contact processes in pressure-measuring piston-cylinder assemblies, and high-pressure components at pressures above 1 GPa. New pressure measuring multipliers were developed and characterised, which allow realisation of the pressure scale up to 1.6 GPa. This characterisation is based on research including measurements of material elastic constants by the resonant ultrasound spectroscopy, hardness of materials of high pressure components, density and viscosity of pressure transmitting liquids at pressures up to 1.4 GPa and dimensional measurements on piston-cylinders. A 1.6 GPa pressure system was created for operation of the 1.6 GPa multipliers and calibration of high pressure transducers. A transfer standard for 1.5 GPa pressure range, based on pressure transducers, was built and tested. Herewith, the project developed the capability of measuring pressures up to 1.6 GPa, from which industrial users can calibrate their pressure measurement devices for accurate measurements up to 1.5 GPa.

Putting to a bigger hole: Golf performance relates to perceived size

Witt, Jessica K.; Linkenauger, Sally A.; Bakdash, Jonathan Z.; Proffitt, Dennis R.

2011-01-01

When engaged in a skilled behaviour such as occurs in sports, people's perceptions relate optical information to their performance. In current research we demonstrate the effects of performance on size perception in golfers. We found golfers who played better judged the hole to be bigger than golfers who did not play as well (Study 1). In follow-up laboratory experiments, participants putted on a golf mat from a location near or far from the hole then judged the size of the hole. Participants who putted from the near location perceived the hole to be bigger than participants who putted from the far location. Our results demonstrate that perception is influenced by the perceiver's current ability to act effectively in the environment. PMID:18567258

Pressure Drop Versus Flow Rate Analysis of the Limited Streamer Tube Gas System of the BaBar Muon Detector Upgrade

International Nuclear Information System (INIS)

Yi, M.

2004-01-01

It has been proposed that Limited Streamer Tubes (LST) be used in the current upgrade of the muon detector in the BaBar detector. An LST consists of a thin silver plated wire centered in a graphite-coated cell. One standard LST tube consists of eight such cells, and two or three such tubes form an LST module. Under operation, the cells are filled with a gas mixture of CO 2 , argon and isobutane. During normal operation of the detector, the gas will be flushed out of the system at a constant low rate of one volume change per day. During times such as installation, however, it is often desired to flush and change the LST gas volumes very rapidly, leading to higher than normal pressure which may damage the modules. This project studied this pressure as a function of flow rate and the number of modules that are put in series in search of the maximal safe flow rate at which to flush the modules. Measurements of pressure drop versus flow rate were taken using a flow meter and a pressure transducer on configurations of one to five modules put in series. Minimal Poly-Flo tubing was used for all connections between test equipment and modules. They contributed less than 25% to all measurements. A ratio of 0.00022 ± 0.00001 mmHg per Standard Cubic Centimeter per Minute (SCCM) per module was found, which was a slight overestimate since it included the contributions from the tubing connections. However, for the purpose of finding a flow rate at which the modules can be safely flushed, this overestimate acts as a safety cushion. For a standard module with a volume of 16 liters and a known safe overpressure of 2 inches of water, the ratio translates into a flow rate of 17000 ± 1000SCCM and a time requirement of 56 ± 5 seconds to flush an entire module

Elastic-Plastic Numerical Analysis of Tunnel Stability Based on the Closest Point Projection Method Considering the Effect of Water Pressure

Directory of Open Access Journals (Sweden)

Zhan-ping Song

2016-01-01

Full Text Available To study the tunnel stability at various static water pressures and determine the mechanical properties and deformation behavior of surrounding rock, a modified effective stress formula was introduced into a numerical integration algorithm of elastic-plastic constitutive equation, that is, closest point projection method (CPPM. Taking the effects of water pressure and seepage into account, a CPPM-based formula was derived and a CPPM algorithm based on Drucker-Prager yield criterion considering the effect of pore water pressure was provided. On this basis, a CPPM-based elastic-plastic numerical analysis program considering pore water pressure was developed, which can be applied in the engineering of tunnels and other underground structures. The algorithm can accurately take the effects of groundwater on stability of surrounding rock mass into account and it can show the more pronounced effect of pore water pressure on stress, deformation, and the plastic zone in a tunnel. The stability of water flooding in Fusong tunnel was systematically analyzed using the developed program. The analysis results showed that the existence of groundwater seepage under tunnel construction will give rise to stress redistribution in the surrounding rock mass. Pore water pressure has a significant effect on the surrounding rock mass.

Increased projection of MHC and tumor antigens in murine B16-BL6 melanoma induced by hydrostatic pressure and chemical crosslinking.

Science.gov (United States)

Ramakrishna, V; Eisenthal, A; Skornick, Y; Shinitzky, M

1993-05-01

The B16-BL6 melanoma, like most spontaneously arising tumors, is poorly immunogenic and expresses low levels of major histocompatibility complex (MHC) antigens. Treatment of cells of this tumor in vitro by hydrostatic pressure in the presence of adenosine 2',3'-dialdehyde (oxAdo), a membrane-impermeant crosslinker, caused elevated projection of MHC and a specific tumor antigen as demonstrated by flow-cytometric analysis. Maximum projection of both the MHC and the tumor antigens could be reached by application of 1200 atm for 15 min in the presence of 20 mM oxAdo. It is not yet clear whether this passive increase in availability of antigens on the cell surface originated from a dormant pool of antigens in the plasma membrane or from pressure-induced fusion of antigen-rich intracellular organelles (e.g. the endoplasmic reticulum). The immunogenic properties of the antigen-enriched B16-BL6 cells are described in the following paper.

George K. Hung

2003-01-01

Full Text Available The objective of this article is to determine the effect of three different putting grips (conventional, cross-hand, and one-handed on variations in eye and head movements during the putting stroke. Seven volunteer novice players, ranging in age from 21 to 22 years, participated in the study. During each experimental session, the subject stood on a specially designed platform covered with artificial turf and putted golf balls towards a standard golf hole. The three different types of grips were tested at two distances: 3 and 9 ft. For each condition, 20 putts were attempted. For each putt, data were recorded over a 3-s interval at a sampling rate of 100 Hz. Eye movements were recorded using a helmet-mounted eye movement monitor. Head rotation about an imaginary axis through the top of the head and its center-of-rotation was measured by means of a potentiometer mounted on a fixed frame and coupled to the helmet. Putter-head motion was measured using a linear array of infrared phototransistors embedded in the platform. The standard deviation (STD, relative to the initial level was calculated for eye and head movements over the duration of the putt (i.e., from the beginning of the backstroke, through the forward stroke, to impact. The averaged STD for the attempted putts was calculated for each subject. Then, the averaged STDs and other data for the seven subjects were statistically compared across the three grip conditions. The STD of eye movements were greater (p < 0.1 for conventional than cross-hand (9 ft and one-handed (3 and 9 ft grips. Also, the STD of head movements were greater (p < 0.1; 3 ft for conventional than cross-hand and one-handed grips. Vestibulo-ocular responses associated with head rotations could be observed in many 9 ft and some 3 ft putts. The duration of the putt was significantly longer (p < 0.05; 3 and 9 ft for the one-handed than conventional and cross-hand grips. Finally, performance, or percentage putts made, was

The MuCap experiment at the Paul Scherrer Institute performed a high-precision measurement of the rate of the basic electroweak process of nuclear muon capture by the proton, μ{sup -} + p → n + ν{sub μ}. The experimental approach was based on the use of a time projection chamber (TPC) that operated in pure hydrogen gas at a pressure of 10bar and functioned as an active muon stopping target. The TPC detected the tracks of individual muon arrivals in three dimensions, while the trajectories of outgoing decay (Michel) electrons were measured by two surrounding wire chambers and a plastic scintillation hodoscope. The muon and electron detectors together enabled a precise measurement of the μp atom's lifetime, from which the nuclear muon capture rate was deduced. The TPC was also used to monitor the purity of the hydrogen gas by detecting the nuclear recoils that follow muon capture by elemental impurities. This paper describes the TPC design and performance in detail. (orig.)

Technology qualification of an ambient pressure subsea cryogenic pipeline for offshore LNG loading and receiving terminals

A project that deploys new technologies need to be confident that the technology can be implemented successfully and will perform reliably as designed. New technology is critical to industry, especially where such technology is a project enable without the existence of a backup solution, but also for projects where such technologies bring potential benefits such as technical, economic, schedule, and environmental improvements. DNV developed and has been implementing for many years a systematic, risk based technology qualification process as described in DNV RP-A203, qualification procedures for new technology. One of the major objectives of a formal technology qualification process is to ensure that risks are properly addressed. The DNV process includes several levels of technology qualification and review, starting with a statement of feasibility and concluding with a Certificate of Fitness for Service. Fluor Corporation (Fluor) has developed a new subsea cryogenic pipe-in-pipe configuration for offshore LNG loading and receiving terminals. The configuration uses a highly efficient thermal nano-porous insulation in the annular space between the inner and outer pipes. This material is kept in an ambient pressure environment, which is produced through sealing by metal bulkheads. The bulkheads transfer the contraction induced axial compression load on the inner cryogenic carrier pipe to the external jacket pipe. The resulting pipeline bundle is a structural element, which addresses the thermal contraction and expansion loads without the use of expansion bellows or ultra-low thermal contraction alloys. Fluor has followed the DNV technology qualification process to achieve the defined milestones therein which culminated in DNV issuing a certificate of fitness for service. Particular focus was put on the new aspects of the design. The certificate of fitness for service for the Fluor subsea LNG pipe technology provides project management with the confidence that this

the goal of this project was to determine the optimum moisture levels for biomass processing for pellets commercially, by correlating data taken from numerous points in the process, and across several different feedstock materials produced and harvested using a variety of different management practices. This was to be done by correlating energy consumption and material through put rates with the moisture content of incoming biomass ( corn & wheat stubble, native grasses, weeds, & grass straws), and the quality of the final pellet product.This project disseminated the data through a public website, and answering questions form universities across Missouri that are engaged in biomass conversion technologies. Student interns from a local university were employed to help collect data, which enabled them to learn firsthand about biomass processing.

Light water reactor pressure vessel (RPV) material properties reduced by long-term exposure to neutron irradiation can be recovered through a thermal annealing treatment. This technique to extend RPV life, discussed in this report, provides a complementary approach to analytical methodologies to evaluate RPV integrity. RPV annealing has been successfully demonstrated in the former Soviet Union and on a limited basis by the US (military applications only). The process of demonstrating the technical feasibility of annealing commercial US RPVs is being pursued through a cooperative effort between the nuclear industry and the US Department of Energy (USDOE) Plant Lifetime Improvement (PLIM) Program. Presently, two projects are under way through the USDOE PLIM Program to demonstrate the technical feasibility of annealing commercial US RPVS, (1) annealing re-embrittlement data base development and (2) heat transfer boundary condition experiments

When FERC investigates your unlicensed project

International Nuclear Information System (INIS)

Swiger, M.A.

1991-01-01

A FERC investigation into a hydropower project's jurisdictional status poses the potential for substantial risks and costs. This paper outlines a five-point protection plan for owners and operators of unlicensed projects potentially subject to FERC jurisdiction. The plan includes the following elements: understand the investigation process; do your homework; respond promptly to FERC deadlines; weigh the costs and benefits of licensing; and be careful not to do something inadvertently to make your project jurisdictional. Based on the plan outlined above, a project owner or operator should be better able to develop a strategy which minimizes risks while maximizing the ability to prevail on the jurisdictional issue. At the very least, such a plan should put the project owner or operator in a better position to achieve a resolution which is acceptable both to the owner or operator and to FERC

By augmenting the bounded rationality assumption to include interpretive limitations, we show that there are sources of costly conflict that are not rooted in opportunism. Moreover, we show...... that bounded rationality may drive opportunism.

De Sitter projective relativity

CERN Document Server

Licata, Ignazio; Benedetto, Elmo

2017-01-01

This book presents the Projective approach to de Sitter Relativity. It traces the development of renewed interest in models of the universe at constant positive curvature such as "vacuum" geometry. The De Sitter Theory of Relativity, formulated in 1917 with Willem De Sitter's solution of the Einstein equations, was used in different fields during the 1950s and 1960s, in the work of H. Bacry, J.M. LevyLeblond and F.Gursey, to name some important contributors. From the 1960s to 1980s, L. Fantappié and G. Arcidiacono provided an elegant group approach to the De Sitter universe putting the basis for special and general projective relativity. Today such suggestions flow into a unitary scenario, and this way the De Sitter Relativity is no more a "missing opportunity" (F. Dyson, 1972), but has a central role in theoretical physics. In this volume a systematic presentation is given of the De Sitter Projective relativity, with the recent developments in projective general relativity and quantum cosmology.

Dual shell pressure balanced reactor vessel. Final project report

International Nuclear Information System (INIS)

Robertus, R.J.; Fassbender, A.G.

1994-10-01

The Department of Energy's Office of Energy Research (OER) has previously provided support for the development of several chemical processes, including supercritical water oxidation, liquefaction, and aqueous hazardous waste destruction, where chemical and phase transformations are conducted at high pressure and temperature. These and many other commercial processes require a pressure vessel capable of operating in a corrosive environment where safety and economy are important requirements. Pacific Northwest Laboratory (PNL) engineers have recently developed and patented (U.S. patent 5,167,930 December 1, 1992) a concept for a novel Dual Shell Pressure Balanced Vessel (DSPBV) which could solve a number of these problems. The technology could be immediately useful in continuing commercialization of an R ampersand D 100 award-winning technology, Sludge-to-oil Reactor System (STORS), originally developed through funding by OER. Innotek Corporation is a small business that would be one logical end-user of the DSPBV reactor technology. Innotek is working with several major U.S. engineering firms to evaluate the potential of this technology in the disposal of wastes from sewage treatment plants. PNL entered into a CRADA with Innotek to build a bench-scale demonstration reactor and test the system to advance the economic feasibility of a variety of high pressure chemical processes. Hydrothermal processing of corrosive substances on a large scale can now be made significantly safer and more economical through use of the DSPBV. Hydrothermal chemical reactions such as wet-air oxidation and supercritical water oxidation occur in a highly corrosive environment inside a pressure vessel. Average corrosion rates from 23 to 80 miles per year have been reported by Rice (1994) and Latanision (1993)

Distance and slope constraints: adaptation and variability in golf putting.

Dias, Gonçalo; Couceiro, Micael S; Barreiros, João; Clemente, Filipe M; Mendes, Rui; Martins, Fernando M

2014-07-01

The main objective of this study is to understand the adaptation to external constraints and the effects of variability in a golf putting task. We describe the adaptation of relevant variables of golf putting to the distance to the hole and to the addition of a slope. The sample consisted of 10 adult male (33.80 ± 11.89 years), volunteers, right handed and highly skilled golfers with an average handicap of 10.82. Each player performed 30 putts at distances of 2, 3 and 4 meters (90 trials in Condition 1). The participants also performed 90 trials, at the same distances, with a constraint imposed by a slope (Condition 2). The results indicate that the players change some parameters to adjust to the task constraints, namely the duration of the backswing phase, the speed of the club head and the acceleration at the moment of impact with the ball. The effects of different golf putting distances in the no-slope condition on different kinematic variables suggest a linear adjustment to distance variation that was not observed when in the slope condition.

2017-12-01

Full Text Available Golfers with disability are limited in the execution of the full golf swing, but their performance in putting may be comparable because this stroke does not demand significant strength, balance and range of motion. Therefore, the aim of this study was to compare putting performance, kinetic and kinematic consistency between golfers with different disabilities and healthy athletes. The participants consisted of three disabled athletes (perinatal cerebral palsy, multiple sclerosis, below knee lower limb amputee and three healthy golfers (age 34 ± 4.5 years, body height 178 ± 3.3 cm, body mass 83 ± 6.2 kg. The golfers’ movements were recorded by active 3D markers for kinematic analyses; the subjects performed 10 trials of a 6 m putting task while standing on separate force platforms placed under each lower limb. Putting performance was measured by the distance of the final ball position to the centre of the hole. ANOVA analyses did not show any differences in clubhead speed and total ball distance from the hole. The consistency of those two parameters expressed by the coefficient of variation (CV was CV = 0.5% or better in both groups for clubhead speed and ranged from CV = 0.40 to 0.61% in healthy and CV = 0.21 to 0.55% in disabled athletes for total error distance. The main effect ANOVA showed differences in weight shift, hip and shoulder kinematics (p < 0.05 between healthy players and all players with disability. All disabled athletes shifted their weight toward the healthy side (towards the healthy lower limb and alternated the end of the swing. The player with below knee amputation had the lowest range of motion in the shoulder joint during the putting stroke. The players with perinatal cerebral palsy and multiple sclerosis had the largest range of motion in the hips. Putting performance of disabled golfers was similar to healthy athletes. During training of disabled players, coaches should pay attention to the specificity of a

Pressure Fluctuation Characteristics of Narrow Gauge Train Running Through Tunnel

Science.gov (United States)

Suzuki, Masahiro; Sakuma, Yutaka

Pressure fluctuations on the sides of narrow (1067 mm) gauge trains running in tunnels are measured for the first time to investigate the aerodynamic force acting on the trains. The present measurements are compared with earlier measurements obtained with the Shinkansen trains. The results are as follows: (1) The aerodynamic force, which stems from pressure fluctuations on the sides of cars, puts the energy into the vibration of the car body running through a tunnel. (2) While the pressure fluctuations appear only on one of the two sides of the trains running in double-track tunnels, the fluctuations in opposite phase on both sides in single-track tunnels. (3) The on-track test data of the narrow gauge trains show the same tendency as those of the Shinkansen trains, although it is suggested that the pressure fluctuations develop faster along the narrow gauge trains than the Shinkansen trains.

A dedicated process control computer has been implemented for regulating the metallurgical Pressure Vessel Wall Benchmark Facility (PSF) at the Oak Ridge Research Reactor. The purpose of the PSF is to provide reliable standards and methods by which to judge the radiation damage to reactor pressure vessel specimens. Benchmark data gathered from the PSF will be used to improve and standardize procedures for assessing the remaining safe operating lifetime of aging reactors. The computer system controls the pressure vessel specimen environment in the presence of gamma heating so that in-vessel conditions are simulated. Instrumented irradiation capsules, in which the specimens are housed, contain temperature sensors and electrical heaters. The computer system regulates the amount of power delivered to the electrical heaters based on the temperature distribution within the capsules. Time-temperature profiles are recorded along with reactor conditions for later correlation with specimen metallurgical changes

Determination of the full elastic constants (c{sub ij}) of methane hydrates (MHs) at extreme pressure-temperature environments is essential to our understanding of the elastic, thermodynamic, and mechanical properties of methane in MH reservoirs on Earth and icy satellites in the solar system. Here, we have investigated the elastic properties of singe-crystal cubic MH-sI, hexagonal MH-II, and orthorhombic MH-III phases at high pressures in a diamond anvil cell. Brillouin light scattering measurements, together with complimentary equation of state (pressure-density) results from X-ray diffraction and methane site occupancies in MH from Raman spectroscopy, were used to derive elastic constants of MH-sI, MH-II, and MH-III phases at high pressures. Analysis of the elastic constants for MH-sI and MH-II showed intriguing similarities and differences between the phases′ compressional wave velocity anisotropy and shear wave velocity anisotropy. Our results show that these high-pressure MH phases can exhibit distinct elastic, thermodynamic, and mechanical properties at relevant environments of their respective natural reservoirs. These results provide new insight into the determination of how much methane exists in MH reservoirs on Earth and on icy satellites elsewhere in the solar system and put constraints on the pressure and temperature conditions of their environment.

We report on pressure-induced structural changes in crystalline oligo(para-phenylenes) containing two to six phenyl rings. The results are discussed with particular emphasis put on the implications these changes in intermolecular distances and molecular arrangement have on important bulk properties of this class of materials, such as optical response and charge transport. We performed energy dispersive x-ray diffraction in a systematic study on polycrystalline powders of biphenyl, para-terphenyl, p-quaterphenyl, p-quinquephenyl and p-sexiphenyl under hydrostatic pressure up to 60 kbar. Revisiting the crystal structures at ambient conditions reveals details in the packing principle. A linear relationship between the density at ambient conditions and the number of phenyl rings is found. High pressure data not only yields pressure-dependent lattice parameters and hints towards pressure-induced changes in the molecular arrangement but also allows for an analysis of the equations of state of these substances as a ...

2008-06-01

Prior eye-tracking studies of spoken sentence comprehension have found that the presence of two potential referents, e.g., two frogs, can guide listeners toward a Modifier interpretation of Put the frog on the napkin... despite strong lexical biases associated with Put that support a Goal interpretation of the temporary ambiguity (Tanenhaus, M. K., Spivey-Knowlton, M. J., Eberhard, K. M. & Sedivy, J. C. (1995). Integration of visual and linguistic information in spoken language comprehension. Science, 268, 1632-1634; Trueswell, J. C., Sekerina, I., Hill, N. M. & Logrip, M. L. (1999). The kindergarten-path effect: Studying on-line sentence processing in young children. Cognition, 73, 89-134). This pattern is not expected under constraint-based parsing theories: cue conflict between the lexical evidence (which supports the Goal analysis) and the visuo-contextual evidence (which supports the Modifier analysis) should result in uncertainty about the intended analysis and partial consideration of the Goal analysis.

Importance of nutrition in preventing and treating pressure ulcers.

Science.gov (United States)

Taylor, Carolyn

2017-06-30

Pressure ulcers are painful, and affect patients' health, mobility and well-being. They also cost the NHS between £1.4-2.1 billion a year. Although a large proportion of pressure ulcers are avoidable, many still occur and, because pressure ulcer incidence is an indicator of care quality, it can put carers under scrutiny. The National Institute for Health and Care Excellence states that adequate risk assessment of pressure ulcer development, including the role of malnutrition, improves care. Adequate nutrition is vital for the prevention of pressure ulcers and malnutrition can hinder healing when pressure ulcers have developed. The risk of malnutrition should be assessed with a recognised tool, such as the Malnutrition Universal Screening Tool, and appropriate treatment plans should be drawn up for patients identified as being at risk of malnutrition to improve their nutritional state. For example, the dietary intake of people with poor appetite can be supplemented with nutritious snacks between meals. The aims of this article are to help readers understand risk factors for malnutrition and how dietary intake can be manipulated to improve patients' nutritional state. It also aims to highlight how improving nutritional intake helps to prevent pressure ulcers. On completing the article, readers will be able to consider and review their own practice.

Kelleher, Alyson Dare; Moorer, Amanda; Makic, MaryBeth Flynn

2012-01-01

We conducted a quality improvement project in order to evaluate the effect of nurse-to-nurse bedside "rounding" as a strategy to decrease hospital-acquired pressure ulcers (HAPU) in a surgical intensive care unit. We instituted weekly peer-to-peer bedside skin rounds in a 17-bed surgical intensive care unit. Two nurses were identified as skin champions and trained by the hospital's certified WOC nurse to conduct skin rounds. The skin champion nurses conducted weekly peer-to-peer rounds that included discussions about key elements of our patients' skin status including current Braden Scale for Pressure Sore Risk score, and implementation of specific interventions related to subscale risk assessment. If a pressure ulcer was present, the current action plan was reevaluated for effectiveness. Quarterly HAPU prevalence studies were conducted from January 2008 to December 2010. Nineteen patients experienced a HAPU: 17 were located on the coccyx and 2 on the heel. Ten ulcers were classified as stage II, 3 PU were stage IV, 5 were deemed unstageable, and 1 was classified as a deep tissue injury. The frequency of preventive interventions rose during our quality improvement project. Specifically, the use of prevention surfaces increased 92%, repositioning increased 30%, nutrition interventions increased 77%, and moisture management increased 100%. Prior to focused nursing rounds, the highest HAPU prevalence rate was 27%. After implementing focused nursing rounds, HAPU rates trended down and were 0% for 3 consecutive quarters.

The largest source of funding for alternative fuel vehicle and infrastructure projects in the U.S. Department of Energy's Clean Cities program's history came from the American Recovery and Reinvestment Act (Recovery Act). In 2009, the 25 cost-share projects totaled nearly $300 million in federal government investment. This effort included the involvement of 50 Clean Cities coalitions and their nearly 700 stakeholder partners who provided an additional $500 million in matching funds to support projects in their local communities. In total, those 25 projects established 1,380 alternative fueling stations and put more than 9,000 alternative fuel and advanced technology vehicles on the road. Together, these projects displaced 154 million gasoline gallon equivalents (GGE) of petroleum and averted 254,000 tons of greenhouse gas (GHG) emissions, while supporting U.S. energy independence and contributing to regional economic development. During post-project interviews, project leaders consistently cited a number of key components - ranging from technical and logistical factors, to administrative capabilities - for accomplishing an effective and impactful project. This report summarizes the high-level project design and administrative considerations for conducting a successful transportation project.

Reservoirs talk to pressure recorders

Energy Technology Data Exchange (ETDEWEB)

Pamenter, C B

1968-02-01

Keeping pace with increased demand for efficiency in secondary recovery schemes is the widening use of downhole tools charged with supplying data before and during the operation of the projects. One of the most important of these is the pressure recorder. This highly sensitive instrument, housed in a tough, slim steel case and lowered by drill pipe or cable, accurately measures the pressure of its downhole environment. This information is instantly available at the surface whenever a pressure reading is required. Typical applications of surface recorders often contribute are: (1) production practices such as checking surface and subsurface equipment, and special lifting problems; (2) well conditions including regular productivity indices, data observations and for interference studies; (3) secondary recovery projects, in both producing and injection wells; and (4) reservoir conditions where oil-water contacts and damaged zones need close attention.

Full Text Available Underwater vehicles play a very important role in underwater engineering. Water-tight junction box (WJB is one of the key components in underwater vehicle. This paper puts forward a pressure self-adaptive water-tight junction box (PSAWJB which improves the reliability of the WJB significantly by solving the sealing and pressure problems in conventional WJB design. By redundancy design method, the pressure self-adaptive equalizer (PSAE is designed in such a way that it consists of a piston pressure-adaptive compensator (PPAC and a titanium film pressure-adaptive compensator (TFPAC. According to hydro-mechanical simulations, the operating volume of the PSAE is more than or equal to 11.6 % of the volume of WJB liquid system. Furthermore, the required operating volume of the PSAE also increases as the gas content of oil, hydrostatic pressure or temperature difference increases. The reliability of the PSAWJB is proved by hyperbaric chamber tests.

The Challenge of Integrating OHS into Industrial Project Risk Management: Proposal of a Methodological Approach to Guide Future Research (Case of Mining Projects in Quebec, Canada

Directory of Open Access Journals (Sweden)

Adel Badri

2015-06-01

Full Text Available Although risk management tools are put to good use in many industrial sectors, some large projects have been met with numerous problems due to failure to take occupational health and safety (OHS into consideration. In spite of the high level of risk and uncertainty associated with many industrial projects, the number of studies of methods for managing all known risks systematically remains small. Under effervescent economic conditions, industries must meet several challenges associated with frequent project start-ups. In highly complex and uncertain environments, rigorous management of risk remains indispensable for avoiding threats to the success of projects. Many businesses seek continually to create and improve integrated approaches to risk management. This article puts into perspective the complexity of the challenge of integrating OHS into industrial project risk management. A conceptual and methodological approach is proposed to guide future research focused on meeting this challenge. The approach is based on applying multi-disciplinary research modes to a complex industrial context in order to identify all scenarios likely to contain threats to humans or the environment. A case study is used to illustrate the potential of the proposed approach for application and its contribution to meeting the challenge of taking OHS into consideration. On-site researchers were able to develop a new approach that helped two mining companies in Quebec (Canada to achieve successful integration of OHS into expansion projects.

Hashemian, H.M.

1991-01-01

This paper presents the key results of an experimental research project conducted for the Nuclear Regulatory Commission to quantify the effects of normal aging on static and dynamic performance of nuclear grade pressure, level, and flow transmitters (hereafter referred to as pressure transmitters). The project involved laboratory testing of representative pressure transmitters manufactured by Barton, Foxboro, Rosemount, and Tobar (or Veritrak) companies. These manufacturers provide the four most commonly used pressure transmitters in the safety systems of US nuclear power plants. The transmitters were tested under normal aging conditions as opposed to accelerated aging, even though accelerated aging will be used in the last few months of the project to determine the weak links and failure modes of the transmitters. The project has been performed in two phases. The Phase 1 project which was a six month feasibility study has been completed and the results published in NUREG/CR-5383. The Phase 2 project is still underway with the final report due in the fall of 1991. The project has focused on the following areas: (1) effects of aging on calibration stability; (2) effects of aging on response time; (3) study of individual components of pressure transmitters that are sensitive to aging degradation; (4) sensing line blockages due to solidification of boron, formation of sludge, freezing, and other effects; (5) search of licensee event reports and component reliability databases for failures of safety-related pressure transmitters; and (6) oil loss syndrome in Rosemount pressure transmitters

Kennedy, Kriss J.

2011-01-01

This paper gives an overview of the National Aeronautics and Space Administration (NASA) led multi-center Habitat Demonstration Unit (HDU) project leadership and management strategies. The HDU project team constructed and tested an analog prototype lunar surface habitat/laboratory called the Pressurized Excursion Module (PEM) during 2010. The prototype unit subsystems were integrated in a short amount of time, utilizing a tiger team approach that brought together over 20 habitation-related technologies and innovations from a variety of NASA centers. This paper describes the leadership and management strategies as well as lessons learned pertaining to leading and managing a multi-center diverse team in a rapid prototype environment. The PEM configuration went from a paper design to an operational surface habitat demonstration unit in less than 12 months. The HDU project is part of the strategic plan from the Exploration Systems Mission Directorate (ESMD) Directorate Integration Office (DIO) and the Exploration Mission Systems Office (EMSO) to test destination elements in analog environments. The 2011 HDU-Deep Space Habitat (DSH) configuration will build upon the PEM work, and emphasize validity of crew operations (remote working and living), EVA operations, mission operations, logistics operations, and science operations that might be required in a deep space context for Near Earth Object (NEO) exploration mission architectures. The 2011 HDU-DSH will be field-tested during the 2011 Desert Research and Technologies Studies (DRaTS) field tests. The HDU project is a "technology-pull" project that integrates technologies and innovations from multiple NASA centers. This project will repurpose the HDU 2010 demo unit that was field tested in the 2010 DRaTS, adding habitation functionality to the prototype unit. This paper will describe the strategy of establishing a multi-center project management team that put in place the key multi-center leadership skills and

Specialised pressure-relieving supports reduce or relieve the interface pressure between the skin and the support surface. The comparative effectiveness of dynamic support surfaces is debated. The aim of this study is to examine the impact of using an alternating pressure air mattress (APAM) on pressure ulcer (PU) incidence in patients receiving home-based care. A second aim was to determine the level of patient/family satisfaction with comfort and gain the views of the care team that used the APAM. The PARESTRY study was a prospective observational study conducted in patients with a high risk of PUs (Braden score prevention groups consisted of patients with no PU at baseline who were in bed for at least 20 hours a day. Patients at baseline with a category 3 or 4 PU or a category 1 or 2 PU in association with poor general health or end-of-life status were included in the secondary prevention group. All patients were laid on an APAM. The primary end point was the % of patients with a worsening skin condition in the pressure area (heel, sacrum, ischium) at day 90 or at the end of the study. The primary analysis was done on the full analysis set (patients included with at least a second assessment), using the last observation carried forward technique to handle missing data, at day 90. A 95% confidence interval was calculated. Analysis was performed on 92 patients (30 in primary prevention and 62 in secondary prevention). The average time spent in bed was 22.7 (SD 2.7) hours a day and 22.6 (SD 2.2) hours in the primary and secondary prevention groups, respectively. At baseline, in the secondary group, 77% of patients had a sacral PU, 63% a heel PU, 8% an ischial tuberosity PU and 45% a PU in another area, a number of patients having multiple PUs. In the primary prevention group, 63% (19/30) of patients dropped out of the study (5 were hospitalised, 9 died, 5 other causes). In the secondary prevention group, 61% (38/62) dropped out (7 were hospitalised, 23 died, 8

Reckless lending: how Canada's Export Development Corporation puts people and environment at risk

Energy Technology Data Exchange (ETDEWEB)

NONE

2000-03-01

This report documents the negative impacts of several projects financed by Canada's Export Development Corporation (EDC), how these investments put people and the environment at risk, and highlights the need for ensuring that EDC, an agency of the Canadian Government, is compelled to uphold public policies and international standards protecting human rights, the environment and the social needs of communities. By way of proving its case, authors of this report describe several international projects --the Three Gorges Dam in China; the Urra Hydro Project in Colombia; the Marcopper Mine in the Philippines; the BioBio Dam in Chile; the Ok Tedi Copper Mine in Papua New Guinea; the Yacyreta Dam in Argentina and Paraguay; and CANDU reactors in Argentina, China, Romania, South Korea and Turkey -- as proof of human rights violations and environmental disasters in which EDC has been an accessory. It is emphasized that unlike the World Bank and the U.S. export credit agencies, EDC is not required to undertake environmental assessment, or to take into account the impact on human rights or communities of project which they help to finance. The authors recommend amendments to the Export Development Act that would require the EDC to disclose information about proposed project at least 60 days before approval by the Board, including description of the project, the terms of financing, along with any environmental, social and human rights information collected. EDC should be required to establish an autonomous accountability mechanism, using the mechanisms of the World Bank Group as a model to track and guide EDC's policy implementation, and to receive and address complaints from external parties affected by EDC-supported activities. EDC should require social, environmental and human rights assessments, using World Bank standards and methodology as the base, and ensure implementation of recommendations by separately specifying them in the contract. EDC should not be

'Full text:' Major automotive companies, including DaimlerChrysler, Ford, Hyundai, Nissan, PSA Peugeot-Citroen, and Toyota, are co-operating in the Hydrogen 700 project at Powertech to establish a global basis for high pressure hydrogen fuel systems for vehicles. The fuel systems will store compressed hydrogen on-board at pressures up to 700 bar (10,000psi). It is anticipated that the 700 bar storage pressure will provide hydrogen powered vehicles with a range comparable to the range of petroleum-fueled vehicles. The Hydrogen 700 project has contracted world leaders in high pressure technologies to provide 700 bar fuel system components for evaluation. The data from these tests will be used as the basis for the development of relevant standards and regulations. In a development that complements the Hydrogen 700 project, Powertech Labs has established the world's first 700 bar hydrogen station for fast filling operations. This prototype station will be used to evaluate the performance of the 700 bar vehicle fuel system components. The presentation will provide an overview of the Hydrogen 700 project. Safety issues surrounding the use of compressed hydrogen gas as a vehicle fuel, as well as the use of higher storage pressures, will be reviewed. Test data involving the fire testing of vehicles containing hydrogen fuel systems will be presented. The project is intended to result in the introduction of 700 bar fuel systems in the next generation of hydrogen powered vehicles. (author)

Background: Data on the efficacy and safety of non-invasive Pelvic Circumferential Compression Devices (PCCDs) is limited. Tissue damage may occur if a continuous pressure on the skin exceeding 9.3 kPa is sustained for more than two or three hours. The aim of this study was to gain insight into the pressure build-up at the interface, by measuring the PCCD-induced pressure when applying pulling forces to three different PCCDs (Pelvic Binder® , SAM-Sling ® and T-POD® ) in a simplified model. Methods: The resulting exerted pressures were measured at four ‘anatomical’ locations (right, left, posterior and anterior) in a model using a pressure measurement system consisting of pressure cuffs. Results: The exerted pressure varied substantially between the locations as well as between the PCCDs. Maximum pressures ranged from 18.9-23.3 kPa and from 19.2-27.5 kPa at the right location and left location, respectively. Pressures at the posterior location stayed below 18 kPa. At the anterior location pressures varied markedly between the different PCCDs. Conclusion: The circumferential compression by the different PCCDs showed high pressures measured at the four locations using a simplified model. Difference in design and functional characteristics of the PCCDs resulted in different pressure build-up at the four locations. When following the manufacturer’s instructions, the exerted pressure of all three PCCDs tested exceeded the tissue damaging level (9.3 kPa). In case of prolonged use in a clinical situation this might put patients at risk for developing tissue damage. PMID:20361001

Negative pressure wound therapy and external fixation device: a simple way to seal the dressing.

Science.gov (United States)

Bulla, Antonio; Farace, Francesco; Uzel, André-Pierre; Casoli, Vincent

2014-07-01

Negative pressure therapy is widely applied to treat lower limb trauma. However, sealing a negative pressure dressing in the presence of an external fixation device may be difficult and time consuming. Therefore, screws, pins, wires, etc, may preclude the vacuum, preventing the plastic drape to perfectly adhere to the foam. To maintain the vacuum, we tried to prevent air leaking around the screws putting bone wax at the junction between the pins and the plastic drape. This solution, in our hands, avoids air leakage and helps maintain vacuum in a fast and inexpensive way.

Multi-Canister overpack design pressure rating

International Nuclear Information System (INIS)

SMITH, K.E.

1998-01-01

The SNF project was directed to increase the MCO pressure rating by the U.S. Department of Energy, Richland Operations Office (RL) unless the action was shown to be cost prohibitive. This guidance was driven by RL's assessment that there was a need to improve margin and reduce risks associated with assumptions supporting the bounding pressure calculation for the MCO Sealing Strategy. Although more recent pressure analyses show a bounding MCO pressure of 50 psig, RL still considers it prudent to retain the pressure margin the 450 psig rating provides. This rating creates a real, clearly definable margin and significantly reduces the risk that the safety basis will be challenged

Leak Rate Quantification Method for Gas Pressure Seals with Controlled Pressure Differential

Science.gov (United States)

Daniels, Christopher C.; Braun, Minel J.; Oravec, Heather A.; Mather, Janice L.; Taylor, Shawn C.

2015-01-01

An enhancement to the pressure decay leak rate method with mass point analysis solved deficiencies in the standard method. By adding a control system, a constant gas pressure differential across the test article was maintained. As a result, the desired pressure condition was met at the onset of the test, and the mass leak rate and measurement uncertainty were computed in real-time. The data acquisition and control system were programmed to automatically stop when specified criteria were met. Typically, the test was stopped when a specified level of measurement uncertainty was attained. Using silicone O-ring test articles, the new method was compared with the standard method that permitted the downstream pressure to be non-constant atmospheric pressure. The two methods recorded comparable leak rates, but the new method recorded leak rates with significantly lower measurement uncertainty, statistical variance, and test duration. Utilizing this new method in leak rate quantification, projects will reduce cost and schedule, improve test results, and ease interpretation between data sets.

Pressurized water reactors: the EPR project

International Nuclear Information System (INIS)

Py, J.P.; Yvon, M.

2007-01-01

EPR (originally 'European pressurized water reactor', and now 'evolutionary power reactor') is a model of reactor initially jointly developed by French and German engineers which fulfills the particular safety specifications of both countries but also the European utility requirements jointly elaborated by the main European power companies under the initiative of Electricite de France (EdF). Today, two EPR-based reactors are under development: one is under construction in Finland and the other, Flamanville 3 (France), received its creation permit decree on April 10, 2007. This article presents, first, the main objectives of the EPR, and then, describes the Flamanville 3 reactor: reactor type and general conditions, core and conditions of operation, primary and secondary circuits with their components, main auxiliary and recovery systems, man-machine interface and instrumentation and control system, confinement and serious accidents, arrangement of buildings.

Pressure anisotropy stabilization of axisymmetric mirror machines

International Nuclear Information System (INIS)

Weitzner, H.

1978-01-01

The stability of a two species, anisotropic pressure, axisymmetric plasma is studied using the guiding center plasma model. Successively, asymptotic expansions are applied appropriate to a long, thin plasma, and to a plasma with flux surfaces close to cylinders. The resultant stability problem may be cast as an ordinary differential equation eigenvalue problem or as a problem in the calculus of variations. It is shown that low beta plasmas cannot be confined and be stable although plasmas may be stable in which the pressure gradients are nonzero where the pressure tends to zero. Stable profiles are given; these profiles include the possibility of field reversed regions. These stable profiles require the anisotropic species to be cold near the axis. Rather than absolute stability, a weaker condition is also considered which for fixed azimuthal mode number vertical-barmvertical-bar puts the point of accumulation of the spectrum of modes on the stable side. It is hoped that such a condition may yield systems stable to vertical-barmvertical-bar small modes although not all values of vertical-barmvertical-bar. This condition is more readily satisfied and allows more reasonable profiles near the axis

Pressure vessel for nuclear reactors

International Nuclear Information System (INIS)

1975-01-01

The invention applies to a pressure vessel for nuclear reactors whose shell, made of cast metal segments, has a steel liner. This liner must be constructed to withstand all operational stresses and to be easily repairable. The invention solves this problem by installing the liner at a certain distance from the inner wall of the pressure vessel shell and by filling this clearance with supporting concrete. Both the concrete and the steel liner must have a lower prestress than the pressure vessel shell. In order to avoid damage to the liner when prestressing the pressure vessel shell, special connecting elements are provided which consist of welded-on fastening elements projecting into recesses in the cast metal segments of the pressure vessel. Their design is described in detail. (TK) [de

Re-energising Europe. Putting the EU on track for 100% renewable energy

Energy Technology Data Exchange (ETDEWEB)

White, A.; Anderson, J. [WWF European Policy Office, Brussels (Belgium)

2013-02-15

The report shows where Europe needs to be by 2030 in order to reach a fully renewable energy system by 2050. The key findings are that Europe has significant untapped potential for cutting energy use and maximising indigenous power sources that could deliver cheaper and more secure energy. However, this potential is at risk because of a lack of political ambition. There is a particular need for greater clarity on policy frameworks for renewable energy and energy efficiency after 2020 just one investment cycle away. Based on recent research by ECOFYS for WWF, by 2030, the EU: (a) could be using at least 38% less energy (compared to a business as usual projection; (b) could be generating more than 40% of its energy from renewable sources, and (c), by doing both, could reduce its energy related greenhouse emissions by 50% compared to 1990 levels. Achieving such levels would put the EU on track to delivering a 100% renewably powered energy system by 2050 at the latest. It should be noted that while biomass use has been assessed based on the global model, a more detailed sustainability vision for biomass use in Europe is needed.

2012-09-01

As the xLPR project moves along, it is important to properly manage the knowledge generated by the different groups. We focus specifically on the knowledge and communications written in files, including general documents, source code and executable files. Data generated through the project are different in nature and, for this reason, need to be treated differently. To that end, ORNL put in place a series of tools that facilitate proper storage and management of project data, document and code changes, group collaboration, knowledge transfer, transparency, accountability and auditability. This paper describes the approaches/tools that we recommend for moving the project forward on knowledge management.

2016-09-01

Full Text Available The aim of this study was to analyse transfer of mechanical energy between body segments during the glide shot put. A group of eight elite throwers from the Polish National Team was analysed in the study. Motion analysis of each throw was recorded using an optoelectronic Vicon system composed of nine infrared camcorders and Kistler force plates. The power and energy were computed for the phase of final acceleration of the glide shot put. The data were normalized with respect to time using the algorithm of the fifth order spline and their values were interpolated with respect to the percentage of total time, assuming that the time of the final weight acceleration movement was different for each putter. Statistically significant transfer was found in the study group between the following segments: Right Knee – Right Hip (p = 0.0035, Left Hip - Torso (p = 0.0201, Torso – Right Shoulder (p = 0.0122 and Right Elbow – Right Wrist (p = 0.0001. Furthermore, the results of cluster analysis showed that the kinetic chain used during the final shot acceleration movement had two different models. Differences between the groups were revealed mainly in the energy generated by the hips and trunk.

women put up with less”—and that the report was, in effect, invalid. In this article we outline the discursive space that emerges when the mass media seeks to tackle symptoms of inequality in Denmark. We argue that the ideology of gender equality comes to construct a dominant discourse, which silences...... symptoms of inequality. Thereby, gendered violence in Denmark is rendered invisible in public awareness.......Denmark is a country that has been heralded for its high levels of gender equality for decades. One would have expected, then, that the recent EU report that ranked Denmark as the EU-member country with the highest occurrence of physical violence towards women would have created a public uproar...

Reservoir Characterization and CO2 Plume Migration Modeling Based on Bottom-hole Pressure Data: An Example from the AEP Mountaineer Geological Storage Project

Science.gov (United States)

Mishra, Srikanta; Kelley, Mark; Oruganti, YagnaDeepika; Bhattacharya, Indra; Spitznogle, Gary

2014-05-01

We present an integrated approach for formation permeability estimation, front tracking, reservoir model calibration, and plume migration modeling based on injection rate and down-hole pressure data from CO2 geologic sequestration projects. The data are taken from the 20 MW CO2 capture and storage project at American Electric Power's Mountaineer Plant in West Virginia, USA. The Mountaineer CO2 injection system consists of two injection wells - one in the Copper Ridge Dolomite formation and one in the Rose Run sandstone formation, and three deep observation wells that were operational between October 2009 and May 2011. Approximately 27000 MT and 10000 MT were injected into the Copper Ridge dolomite formation and Rose Run sandstone formation, respectively. A wealth of pressure and rate data from injection and observation wells is available covering a series of injection and pressure falloff events. The methodology developed and applied for interpreting and integrating the data during reservoir analysis and modeling from the Rose Run formation is the subject of this paper. For the analysis of transient pressure data at the injection and observation wells, the CO2 storage reservoir is conceptualized as a radial composite system, where the inner (invaded) zone consists of both supercritical CO2 and brine, and the outer (uninvaded) zone consists of undisturbed brine. Using established analytical solutions for analyzing fluid injection problems in the petroleum reservoir engineering literature, we show how the late-time pressure derivative response from both injection and observation wells will be identical - reflecting the permeability-thickness product of the undisturbed brine-filled formation. We also show how the expanding CO2 plume affects the "effective" compressibility that can be estimated by history matching injection-falloff data and how this can be used to develop a relationship between the plume radius and "effective" compressibility. This provides a novel non

Effects of Business Model Development Projects on Organizational Culture: A Multiple Case Study of SMEs

Directory of Open Access Journals (Sweden)

Ulla Santti

2017-08-01

Full Text Available Previous research has shown that links between organizational culture and innovativeness/performance may act as a “social glue” that helps a company develop organizational culture as a competitive advantage. In this study of three case companies, the organizational culture change due business model development projects is studied using the Competing Values Framework (CVF tool and interviews with respondents about discovered changes. To reveal intervention and implied effects between business model development project and organizational culture changes, we used CIMO logic (context, intervention, mechanism, and outcome to bridge practice and theory by explanatory, backward-looking research. Our case studies of companies in relatively short-duration business model development projects indicate that organizational culture may have some dynamic characteristics, for example, an increase of the adhocracy organizational type in all case companies or an increase in the hierarchical leadership type in one case company. Thus, the development of an organizational culture type can be partly controlled. Our results also indicated business model development projects do have a minor effect on organizational culture, even when development activities have not been put fully into practice. However, the more comprehensively business model development project activities have been put into practice, the larger the effect on organizational culture.

Analysis of specific factors causing RCS pressure boundary cracking

As nuclear power plants become aged, pressure boundary integrity has become so important issue in domestic and foreign nuclear industry that many related research projects are on-going. KEPRI is going to embark a new research project for managing and preventing these kinds of cracks in nuclear power plants (NPPs). Many nuclear power plants experienced pressure boundary stress corrosion cracking (SCC) and shut downed because of it. In USA, V.C. Summer plant experienced reactor coolant pipe SCC near reactor outlet nozzle and Davis Vesse plant experienced reactor head crack around penetration pipe which is used to control rod drive mechanism. In this paper, RCS pressure boundary cracking cases and corrosion potential have been studied to find out what are the specific factors that have affected crack initiations in the reactor coolant pressure boundaries

2017-07-01

It is difficult for humans to apply small amounts of force precisely during motor control. However, experts who have undergone extended training are thought to be able to control low-velocity movement with precision. We investigated the resolution of motor control in golf putting. A total of 10 professional and 10 high-level amateur golfers participated. Putting distances were 0.6-3.3 m, in increments of 0.3 m. We measured the impact velocity and the club-face angle at impact, and the acceleration profile of the downswing. The professionals showed significantly smaller coefficients of variation with respect to impact velocity and smaller root mean square errors in relation to acceleration profiles than did the amateurs. To examine the resolution of motor control for impact velocity, we investigated intra-participant differences in the impact velocity of the club head at two adjacent distances. We found that professionals had higher velocity precision when putting small distance intervals than did amateurs. That is, professionals had higher resolution of low-velocity control than did high-level amateurs. Our results suggest that outstanding performance at a task involves the ability to recognise small distinctions and to produce appropriate movements.

Study on effective prestressing effects on concrete containment under the design-basis pressure condition

International Nuclear Information System (INIS)

Sun Feng; Pan Rong; Wang Lu; Mao Huan; Yang Yu

2013-01-01

Prestressing technology is widely used in nuclear power plant containment building, and the durability of containment structure is affected directly by the distribution and loss of prestressing value under design-basis pressure. Containment structure and the distribution of prestressing system are introduced briefly. Furthermore, the calculating process of horizontal prestressing bunch loss near the equipment hatch hole is put forward in details, and the containment structure prestressing loss when 5-year pressure test is obtained. Based above analysis, the finite element model of the prestressed concrete containment structure is built by using ANSYS code, the prestressing effect on concrete containment is analysed. The results show that most of the design pressure is bore by the prestressing system under the design-basis pressure, so the containment structure is safe. These conclusions are consistent with prestressing containment system design concepts, which can provide reference to the engineering staff. (authors)

An Index to Measure Sustainability of a Business Project in the Construction Industry: Lithuanian Case

Directory of Open Access Journals (Sweden)

Nomeda Dobrovolskienė

2015-12-01

Full Text Available The continuous growth of the world population, resource scarcity and the threat of climate change pose numerous environmental and social problems to the world. Therefore, much hope is put in the concept of sustainability. Companies are increasingly coming under strong global pressure to incorporate sustainability considerations into their project decision-making process. Business projects in the construction industry are among the most important, as this sector is one of the largest sectors and of major importance for the national economy and therefore has a huge impact on the environment and society. Thus, we have to explore ways to integrate sustainability into the management of those projects. This paper presents a composite sustainability index of a project (CSIP which has been created following a review of existing literature and a pilot research study. A pilot research study was conducted in the Lithuanian construction industry between January 2015 and June 2015. Sustainability criteria were chosen and grouped on the basis of the analysis of the literature and different standards relating to sustainability applicable in the construction industry. A survey was used to select and rank the most important sustainability criteria. The index was constructed using multi-criteria decision-making methods. The results of the pilot study revealed that practitioners in the Lithuanian construction sector attach most importance to 15 sustainability criteria. A composite sustainability index of a project combining all these criteria may be useful in assessing the sustainability of a business project and making decisions regarding project portfolio selection and financial resource allocation. When addressing the issue of financial resource allocation in a project portfolio, the decision-maker could take into account not only the project’s return and risk, but also its sustainability. The understanding of this study should enable companies to execute

Since 1980, Sandia National Laboratory has been designing and constructing Particle Beam Fusion Accelerator II. One managerial challenge of a large project is the problem of handling information. The scope of the PBFA-II projet may be gauged by its cost: $19.4 million for the accelerator itself, $9.5 million for buildings and standard utilities, and $9.6 million for specialized utilities and support systems. The first need of the project at its outset, then, was communication, and this remains a chief function of the CPO. If the nature or magnitude of the risk changes in any one area, the entire project team must know. If a design is changed, persons working on interdependent efforts must know. Some of this communication takes place naturally and informally. But project procedures must guarantee that all important communication is received by all necessary people, that the communication creates accountability, and that management receives timely, accurate reports. To put it another way, important communication requires project documentation. Documentation is both a record of the project and a tool for management

The management of solid residues has, in recent decades, been a source of concern for public administrators the world over. Experiments in the sustainable use of such residues are highly relevant in social and environmental terms, stimulating widespread interest and debate, with considerable research going into sustainability projects. In many areas, however, adequate public funding for sustainable-use projects is hard to come by. One of the major reasons for this is that public authorities, particularly in times of financial constraints, are reluctant to invest in undertakings in which the economic returns are difficult to quantify. Official scrutiny of the expenditures of public authorities is also normally heavily influenced by cost-benefit analyses. The specific objective of this article is to show that putting solid domestic residue (household solid waste) to sustainable use is capable of generating economic returns, as well as environmental benefits for society as a whole. These economic returns can be set out in financial statements, which may, in turn, be used to justify expenditures by public authorities on sustainable-use projects and as a basis for further investment in such incentives. We drew on the findings of existing research into sustainable use, undertaken by the Municipal Urban Cleaning Company in the city of Rio de Janeiro, Brazil, to establish a conceptual framework for setting out the economic results of the collection of household solid waste.

Evolution Procedure of Multiple Rock Cracks under Seepage Pressure

Directory of Open Access Journals (Sweden)

Taoying Liu

2013-01-01

Full Text Available In practical geotechnical engineering, most of rock masses with multiple cracks exist in water environment. Under such circumstance, these adjacent cracks could interact with each other. Moreover, the seepage pressure, produced by the high water pressure, can change cracks’ status and have an impact on the stress state of fragile rocks. According to the theory of fracture mechanics, this paper discusses the law of crack initiation and the evolution law of stress intensity factor at the tip of a wing crack caused by compression-shear stress and seepage pressure. Subsequently, considering the interaction of the wing cracks and the additional stress caused by rock bridge damage, this paper proposes the intensity factor evolution equation under the combined action of compression-shear stress and seepage pressure. In addition, this paper analyzes the propagation of cracks under different seepage pressure which reveals that the existence of seepage pressure facilitates the wing crack’s growth. The result indicates that the high seepage pressure converts wing crack growth from stable form to unstable form. Meanwhile, based on the criterion and mechanism for crack initiation and propagation, this paper puts forward the mechanical model for different fracture transfixion failure modes of the crag bridge under the combined action of seepage pressure and compression-shear stress. At the last part, this paper, through investigating the flexibility tensor of the rock mass’s initial damage and its damage evolution in terms of jointed rock mass's damage mechanics, deduces the damage evolution equation for the rock mass with multiple cracks under the combined action of compression-shear stress and seepage pressure. The achievement of this investigation provides a reliable theoretical principle for quantitative research of the fractured rock mass failure under seepage pressure.

Chang, Chau-Hui; Chen, Hui-Ling; Chen, Hsiang-Chi

2007-12-01

Pressure sores are one of the well known problems that occur in hospitals. As the literature on the subject indicates, a lot of money is expended in managing this problem every year, and 12-66% of pressure sores are caused during surgery. Patients who undergo neurosurgical procedures are susceptible to pressure sores because of lengthy operations. We collected data on patients with pressure sores who underwent surgery between May 2004 and August 2004, and found that the incidence of pressure sore in neurosurgical patients was 9.5%, which was the highest among all surgical patients. This project was developed to solve the problem of pressure sores by setting up standard preventive procedures, a nursing follow up system and continuing education courses, and utilizing cotton rolls to pad sites of pressure sores. The incidence of pressure sore in neurosurgical patients was reduced from 9.5% to 7% after the improvement project was carried out. The more concerned nurses are about pressure sores, the better the quality of operative nursing care.

The herein concerned bill project results from one of the axes of the Plan for Climate presented by Nicolas Hulot, the French minister of ecological transition, and which announced the decision 'to leave hydrocarbons under the ground'. This text thus aims at putting an end to hydrocarbon exploration and exploitation by 2040, and at implementing measures to ensure the security of natural gas supply, and to protect electric power and gas final consumers. The report first outlines the ambitious character of this bill project, and that support measures are necessary on the medium term. It also discusses reforms to be implemented regarding gas storage, how the single contract is to legally made secure. The commission works are then transcribed, with a general debate and a discussion of bill project articles which address the end of hydrocarbon exploration and exploitation, gas storages and consumers, relationships between providers and network operators, the control of bio-fuels, and the reduction of emissions of some atmospheric pollutants. Appendices contain list of currently valid concessions and mining permits

We take a concrete pumping station as an example in this paper. Through the calculation of water hammer protection with a specific pumping station water supply project, and the analysis of the principle, mathematical models and boundary conditions of air vessel and over-pressure relief valve we show that the air vessel can protect the water conveyance system and reduce the transient pressure damage due to various causes. Over-pressure relief valve can effectively reduce the water hammer because the water column re-bridge suddenly stops the pump and prevents pipeline burst. The paper indicates that the combination set of air vessel and over-pressure relief valve can greatly reduce the quantity of the air valve and can eliminate the water hammer phenomenon in the pipeline system due to the vaporization and water column separation and re-bridge. The conclusion could provide a reference for the water hammer protection of long-distance water supply system

When a supermassive black hole at the centre of a galaxy accretes matter, it gives rise to a highly energetic phenomenon: an active galactic nucleus. Numerous physical processes have been proposed to account for the funnelling of gas towards the galactic centre to feed the black hole. There are also several physical processes that can remove gas from a galaxy, one of which is ram-pressure stripping by the hot gas that fills the space between galaxies in galaxy clusters. Here we report that six out of a sample of seven 'jellyfish' galaxies-galaxies with long 'tentacles' of material that extend for dozens of kiloparsecs beyond the galactic disks-host an active nucleus, and two of them also have galactic-scale ionization cones. The high incidence of nuclear activity among heavily stripped jellyfish galaxies may be due to ram pressure causing gas to flow towards the centre and triggering the activity, or to an enhancement of the stripping caused by energy injection from the active nucleus, or both. Our analysis of the galactic position and velocity relative to the cluster strongly supports the first hypothesis, and puts forward ram pressure as another possible mechanism for feeding the central supermassive black hole with gas.

Kryolize - KT Fund Project

2016-01-01

Safety standards and best practices do exist in the field of cryogenics but, as in most domains, they are generally inserted in a few ‘envelope’ cases commonly used in the industry, whereas applicability to the particularity of research facilities are not fully tailored to its needs. The main objective in these cases is to find a harmonised approach, based on lessons learnt and scientific knowledge. The Kryolize Project was created in order to produce tools with a harmonized approach to size pressure relief devices for cryogenic applications. In view of disseminating such tools to other institutes and industrial partners, the project was submitted to CERN’s KT Fund committee. This talk will focus on the process and deliverables of the KT-Funded Kryolize project, including the method on how to cope with the sizing of pressure relief devices and the R&D collaboration agreement between CERN and Karlsruhe Institute of Technology for an experimental programme.

Experimental study on pressure wave propagation through the open end of pipe

International Nuclear Information System (INIS)

Yoshida, K.; Kumagai, H.

1994-01-01

The steam generators of a double pool type liquid metal fast breeder reactor (LMFBR) are used in a large sodium pool which is formed between the primary vessel and the secondary vessel and accommodates the entire secondary heat transport system. Therefore, if there is a sodium-water reaction event in the steam generator, it becomes important to evaluate the pressure rises at the walls of the primary and secondary vessels as well as those at the other secondary components. An experimental study was performed, focusing on the propagation of the initial pressure spike of the-sodium-water reaction from the bottom end of the steam generator to the sodium pool. Pressure wave propagation from inside of a pipe to an open space through the pipe end was measured. Two kinds of pressure propagation media, water and air, ensured a wide range of experimental conditions. The experimental results revealed that the pressure attenuation at the open end of a pipe can be put in order using the concept of inertial length, and that the dimensionless inertial length, i.e., the inertial length divided by the half wave length of the pressure pulse, is proportional to the square of the dimensionless diameter. These results provide a prediction method for a pressure rise by the initial pressure spike in the secondary sodium pool of the Double Pool LMFBR

To each of three classes one of the three approaches was applied as well as 8 sessions alternating with three assessment sessions. The results showed that performance of trainees after using of the first approach (APA was relatively better than that was achieved with using of other two approaches, especially when training of complex motor tasks, specific to the chosen style of throwing. This allows to deduce the existence of a relationship between complexity of the motor action to be reproduce and interpretation of audiovisual messages, presented by the coach in the middle of training cycle.

Full Text Available One of the main financial statements is the Cash Flow. It became mandatory from the law # 11,638/2007 on, which changed the law # 6,404/1976 – the Corporations’ law, and the Cash Flow statement allows analysis about the companies’ operations activities effects, investing and financing, highlighting their main sources of financial allocation. In 2005 and 2006, 37 companies registered takeover bids in the Brazilian Securities Exchange Commission (CVM – Comissão de Valores Mobiliários. Based on these companies’ analysis of Projected Cash Flows (FCP – Fluxos de Caixa Projetados when the takeover bids were put in place and their Actual Cash Flows (FCR – Fluxo de Caixa Realizados the objective of this work was to compare those cash flows, to analyze the differences between the Statements of Cash Flows attached to the Appraisal Reports and the actual ones, as well as to check if these companies’ cash were in line with the balances projected in the takeover bids. The obtained results via statistical analysis of differences between the Projected Cash Flows attached to the Appraisal Reports and the effective Actual Cash Flows, all of them compared in the period between 2007 and 2013, did not show significant differences among them. IE: it was observed that, nevertheless the companies did not accomplish the promised Cash Flows delivery when the OPAs were put in place, the differences between the balances projected and the actual ones were not statistically significant.

External randomness exists in all sports but is perhaps most obvious in golf putting where robotic putters sink only 80% of 5 m putts due to unpredictable ball-green dynamics. The purpose of this study was to test whether physical randomness training can improve putting performance in novices. A virtual random-physics golf-putting game was developed based on controlled ball-roll data. Thirty-two subjects were assigned a unique randomness gain (RG) ranging from 0.1 to 2.0-times real-world randomness. Putter face kinematics were measured in 5 m laboratory putts before and after five days of virtual training. Performance was quantified using putt success rate and "miss-adjustment correlation" (MAC), the correlation between left-right miss magnitude and subsequent right-left kinematic adjustments. Results showed no RG-success correlation (r = -0.066, p = 0.719) but mildly stronger correlations with MAC for face angle (r = -0.168, p = 0.358) and clubhead path (r = -0.302, p = 0.093). The strongest RG-MAC correlation was observed during virtual training (r = -0.692, p golf putting kinematics. Adaptation to external physical randomness during virtual training may therefore help golfers adapt to external randomness in real-world environments.

Aging characteristics of nuclear plant RTDs and pressure transmitters

Resistance Temperature Detectors (RTDs) and pressure, level, and flow transmitters provide almost all the vital signals that are used for the control and safety of nuclear power plants. Therefore, it is crucial to ensure that the performance of these sensors remain acceptable as they age in the process under normal operating conditions. Four comprehensive research projects were conducted for the U.S. Nuclear Regulatory Commission (NRC) to evaluate the effects of normal aging on calibration stability and response time of RTDs and pressure transmitters of the types used for safety-related measurements in nuclear power plants. Each project was conducted over a three year period. The projects involved laboratory testing of representative RTDs and pressure transmitters aged in simulated reactor conditions. The main purpose of these projects was to establish the degradation rate of the sensors and use the information to determine if the current testing intervals practiced by the nuclear power industry are adequate for management of aging of the sensors. The results have indicated that the current nuclear industry practice of testing the response time and calibration of the sensors once every fuel cycle is adequate. (author)

The Posture of Putting One's Palms Together Modulates Visual Motion Event Perception.

Science.gov (United States)

Saito, Godai; Gyoba, Jiro

2018-02-01

We investigated the effect of an observer's hand postures on visual motion perception using the stream/bounce display. When two identical visual objects move across collinear horizontal trajectories toward each other in a two-dimensional display, observers perceive them as either streaming or bouncing. In our previous study, we found that when observers put their palms together just below the coincidence point of the two objects, the percentage of bouncing responses increased, mainly depending on the proprioceptive information from their own hands. However, it remains unclear if the tactile or haptic (force) information produced by the postures mostly influences the stream/bounce perception. We solved this problem by changing the tactile and haptic information on the palms of the hands. Experiment 1 showed that the promotion of bouncing perception was observed only when the posture of directly putting one's palms together was used, while there was no effect when a brick was sandwiched between the participant's palms. Experiment 2 demonstrated that the strength of force used when putting the palms together had no effect on increasing bounce perception. Our findings indicate that the hands-induced bounce effect derives from the tactile information produced by the direct contact between both palms.

In this paper, a novel antenna is proposed for high-temperature testing, which can make the high-temperature pressure characteristics of a wireless passive ceramic pressure sensor demonstrated at up to a temperature of 600 °C. The design parameters of the antenna are similar to those of the sensor, which will increase the coupling strength between the sensor and testing antenna. The antenna is fabricated in thick film integrated technology, and the properties of the alumina ceramic and silver ensure the feasibility of the antenna in high-temperature environments. The sensor, coupled with the ceramic antenna, is investigated using a high-temperature pressure testing platform. The experimental measurement results show that the pressure signal in a harsh environment can be detected by the frequency diversity of the sensor.

Project management at a university

Eaton, Joel A.

2006-06-01

Managing instrumentation projects, large or small, involves a number of common challenges-defining what is needed, desiging a system to provide it, producing it in an economical way, and putting it into service expeditiously. Doing these things in a university environoment provides unique challenges and opportunities not obtaining in the environment of large projects at NASA or national labs. I address this topic from the viewpoint of knowledge of two such projects, the development of OAO-2 at the University of Wisconsin and the relocation of Fairborn Observatory to the Patagonia Mountains in Arizona, as well as my own developemnt of the Tennessee State 2-m Automatic Spectroscopic Telescope. For the university environment, I argue for a more traditional management style that relies on more informal techniques than those used in large-scale projects conducted by big bureaucratic institutions. This style identifies what tasks are really necessary and eliminates as much wasteful overhead as possible. I discuss many of the formalities used in project management, such as formal reviews (PDR, CDR, etc.) and Gantt charts, and propose other ways of acheving the same results more effectively. The university environment acutely requires getting the right people to do the project, both in terms of their individual personalities, motivation, and technical skills but also in terms of their ability to get on with one another. Two critical challenges confronting those doing such projects in universities are 1) keeping the contractors on task (the major challenge to anyone doing project management) and 2) dealing with the purchasing systems in such institutions.

ArthroCare is a medical device company that develops, manufactures, and markets an advanced surgical tool, a plasma electro-surgical system for cutting and removing tissue. The hand-held electrical discharge device produces plasma in a biocompatible conductive fluid and tissue to which it is applied during surgery. Its products allow surgeons to operate with increased precision and accuracy, limiting damage to surrounding tissue thereby reducing pain and speeding recovery for the patient. In the past, the design of ArthfoCare's plasma wands has been an empirical undertaking. One goal of this R&D program was to put the phenomena involved on a sound scientific footing, allowing optimization of existing plasma based electro-surgery system technology, and the design and manufacture of new and improved kinds of scalpels, in particular for the surgical cutting of bone. Another important related goal of the program was to develop, through an experimental approach, new plasma wand approaches to the cutting ('shaving') of hard bone tissue. The goals of the CRADA were accomplished - computer models were used to predict important parameters of the plasma discharge and the bone environment, and several different approaches to bone-shaving were developed and demonstrated. The primary goal of the project was to develop and demonstrate an atmospheric-pressure plasma tool that is suitable for surgical use for shaving bone in humans. This goal was accomplished, in fact with several different alternative plasma approaches. High bone ablation speeds were measured.

Colorectal perforation by self-induced hydrostatic pressure: a report of two cases.

Science.gov (United States)

Choi, Pyong Wha

2013-02-01

Most iatrogenic colorectal perforations occur as a result of endoscopic or fluoroscopic studies. Accidents associated with hydrostatic pressure-induced perforation are rarely reported, and self-induced hydrostatic pressure is an extremely rare cause of perforation because the anal sphincter complex may provide a protective barrier against perianal hydrostatic pressure. We present two cases of rectosigmoid colon perforation secondary to self-induced hydrostatic pressure. A 61-year-old man and a 45-year-old man presented with abdominal pain after forceful entry of tap water into the rectum, during rinsing of the anus after defecation in the first case, and during self-administered enema in the second case. Emergency operations were performed with the suspicion of hydrostatic pressure-induced rectal injury, and showed rectosigmoid mesenteric perforation in both cases. Resection of the diseased segment and end colostomy (Hartmann's procedure) was performed in the first case, and primary resection and anastomosis in the second case. The pathologic results showed abrupt loss of the colonic wall in the mesenteric border, without evidence of other inflammatory disease; these findings were consistent with acute mechanical colon injury. The postoperative course in both cases was uneventful. These cases put forth an unusual type of colorectal injury, caused specifically by hydrostatic pressure, thus adding to the available literature on hydrostatic pressure-induced injury.

In the LISSAC project (LImit Strains in Severe ACcidents), partly funded by the EC Nuclear Fission and Safety Programme within the 5th Framework programme, an extensive experimental and computational research programme is conducted to study the stress state and size dependence of ultimate failure strains. The results are aimed especially to make the assessment of severe accident cases more realistic. For the experiments in the LISSAC project a block of material of the German Biblis C reactor pressure vessel was available. As part of the project, eight reactor pressure vessel head models from this material (22 NiMoCr 3 7) were tested up to rupture at VTT. The specimens were provided by Forschungszentrum Karlsruhe (FzK). These tests were performed under quasistatic pressure load at room temperature. Two specimens sizes were tested and in half of the tests the specimens contain holes describing the control rod penetrations of an actual reactor pressure vessel head. These specimens were equipped with an aluminium liner. All six tests with the smaller specimen size were conducted successfully. In the test with the large specimen with holes, the behaviour of the aluminium liner material proved to differ from those of the smaller ones. As a consequence the experiment ended at the failure of the liner. The specimen without holes yielded results that were in very good agreement with those from the small specimens. (author)

Dissemination and Exploitation: Project Goals beyond Science

Science.gov (United States)

Hamann, Kristin; Reitz, Anja

2017-04-01

Dissemination and Exploitation are essential parts of public funded projects. In Horizon 2020 a plan for the exploitation and dissemination of results (PEDR) is a requirement. The plan should contain a clear vision on the objectives of the project in relation to actions for dissemination and potential exploitation of the project results. The actions follow the basic idea to spread the knowledge and results gathered within the project and face the challenge of how to bring the results into potentially relevant policy circle and how they impact the market. The plan follows the purpose to assess the impact of the project and to address various target groups who are interested in the project results. Simply put, dissemination concentrates on the transfer of knowledge and exploitation on the commercialization of the project. Beyond the question of the measurability of project`s impact, strategies within science marketing can serve purposes beyond internal and external communication. Accordingly, project managers are facing the challenge to implement a dissemination and exploitation strategy that ideally supports the identification of all partners with the project and matches the current discourse of the project`s content within the society, politics and economy. A consolidated plan might unite all projects partners under a central idea and supports the identification with the project beyond the individual research questions. Which applications, strategies and methods can be used to bring forward a PEDR that accompanies a project successfully and allows a comprehensive assessment of the project afterwards? Which hurdles might project managers experience in the dissemination process and which tasks should be fulfilled by the project manager?

Cheng, G W; Zhou, Z L; Men, Q Y; Deng, C N

2006-01-01

The pressure of the hydro-mechanical continuously variable transmission (HMCVT) is not only one of the major factors affecting the performance of the power train but also the major control parameter of the HMCVT control system. So how to improve the high accuracy hydraulic pressure parameter for the HMCVT control system will be one of the key technologies in system development. Based on the HMCVT test system for a certain tracked vehicle, the hydraulic pressure is studied, and multi-sensor data fusion technology based on Taylor polynomial regression equation is put forward, which turn out to improve the performance of the pressure sensor. Utilizing the above-mentioned method, the ability of antijamming of the hydraulic screen pressure system of the HMCVT is effectively improved, and the validity of the test data in the test system is improved too

Westinghouse Hanford Company Project W-211 is responsible for providing the system capabilities to remove radioactive waste from ten double-shell tanks used to store radioactive wastes on the Hanford Site in Richland, Washington. The project is also responsible for measuring tank waste slurry properties prior to injection into pipeline systems, including the Replacement of Cross-Site Transfer System. This report summarizes studies of the appropriateness of the instrumentation specified for use in Project W-211. The instruments were evaluated in a test loop with simulated slurries that covered the range of properties specified in the functional design criteria. The results of the study indicate that the compact nature of the baseline Project W-211 loop does not result in reduced instrumental accuracy resulting from poor flow profile development. Of the baseline instrumentation, the Micromotion densimeter, the Moore Industries thermocouple, the Fischer and Porter magnetic flow meter, and the Red Valve Pressure transducer meet the desired instrumental accuracy. An alternate magnetic flow meter (Yokagawa) gave nearly identical results as the baseline fischer and Porter. The Micromotion flow meter did not meet the desired instrument accuracy but could potentially be calibrated so that it would meet the criteria. The Nametre on-line viscometer did not meet the desired instrumental accuracy and is not recommended as a quantitative instrument although it does provide qualitative information. The recommended minimum set of instrumentation necessary to ensure the slurry meets the Project W-058 acceptance criteria is the Micromotion mass flow meter and delta pressure cells

Successful application of MPD (managed pressure drilling) for prevention, control, and detection of borehole ballooning in tight gas reservoir in Cuervito Field, Mexico

The Cuervito field is an oil play located in the Burgos Basin in northeastern Mexico. In order to reach the highest yielding sands, wells in the Cuervito field are usually set up with 3 casings. However, the ballooning effect, an elastoplastic behavior of a well's walls, occurs during drilling operations, leading to loss of circulation. Two methods, based on geological and geopressure data, were found to minimize this effect: either putting in an extra casing, or using an unconventional drilling technique. As the managed pressure drilling (MPD) technique is less complex and more elegant, a pilot project was implemented using this method on a well. Results showed that MPD minimized lost time and enhanced drilling efficiency. This paper demonstrated that the use of MPD in the Cuervito field is a good solution for identifying and controlling the ballooning effect and this technique was successfully applied to the next 3 wells drilled subsequently.

Integrated main coolant pumps for pressurized-water reactors

Wieser, R.

1975-01-01

The efficiency of an integrated main coolant pump for PWR's is increased. For this purpose, the pump is installed eccentric relative to the vertical axis of the U-type steam generator in the three-section HP chamber in such a way that its impeller wheel and the shell of the latter penetrate into the outlet chamber. The axis of the pump lies in the vertical plane of symmetry of the outlet chamber of the steam generator. The suction tube is arranged in the outlet chamber. To allow it to be installed, it is manufactured out of several parts. The diffusor tube, which is also made of several components, is attached to the horizontal separation plate between the outlet chamber and the pressure chamber so as to penetrate into it. To improve the outflow conditions at the diffusor tube, a plowshare-shaped baffle shield is installed between the diffusor tube and the HP chamber. Moreover, in order to improve the outflow conditions from the pump and from the pressure chamber, the outflow opening of the pressure chamber is put into the cylindrical shell of the HP chamber. In this way, the tensioning anchor is located between the pump and the outlet opening. (DG/RF) [de

The quality of early bystander CPR appears important in maximizing survival. This trial tests whether explicit instructions to "put the phone down" improve the quality of bystander initiated dispatch-assisted CPR. In a randomized, double-blinded, controlled trial, subjects were randomized to a modified version of the Medical Priority Dispatch System (MPDS) version 11.2 protocol or a simplified protocol, each with or without instruction to "put the phone down" during CPR. Data were recorded from a Laerdal Resusci Anne Skillreporter manikin. A simulated emergency medical dispatcher, contacted by cell phone, delivered standardized instructions. Primary outcome measures included chest compression rate, depth, and the proportion of compressions without error, with correct hand position, adequate depth, and total release. Time was measured in two distinct ways: time required for initiation of CPR and total amount of time hands were off the chest during CPR. Proportions were analyzed by Wilcoxon rank sum tests and time variables with ANOVA. All tests used a two-sided alpha-level of 0.05. Two hundred and fifteen subjects were randomized-107 in the "put the phone down" instruction group and 108 in the group without "put the phone down" instructions. The groups were comparable across demographic and experiential variables. The additional instruction to "put the phone down" had no effect on the proportion of compressions administered without error, with the correct depth, and with the correct hand position. Likewise, "put the phone down" did not affect the average compression depth, the average compression rate, the total hands-off-chest time, or the time to initiate chest compressions. A statistically significant, yet trivial, effect was found in the proportion of compressions with total release of the chest wall. Instructions to "put the phone down" had no effect on the quality of bystander initiated dispatcher-assisted CPR in this trial.

Systematic impact of institutional pressures on safety climate in the construction industry.

He, Qinghua; Dong, Shuang; Rose, Timothy; Li, Heng; Yin, Qin; Cao, Dongping

2016-08-01

This paper explores how three types of institutional pressure (i.e., coercive, mimetic and normative pressures) systematically impact on the safety climate of construction projects. These impacts are empirically tested by survey data collected from 186 questionnaires of construction companies operating in Shanghai, China. The results, obtained by partial least squares analysis, show that organizational management commitment to safety and employee involvement is positively related to all three institutional pressures, while the perception of responsibility for safety and health is significantly influenced by coercive and mimetic pressure. However, coercive and normative pressures have no significant effect on the applicability of safety rules and work practices, revealing the importance of external organizational pressures in improving project safety climate from a systematic view. The findings also provide insights into the use of institutional forces to facilitate the improvement of safety climate in the construction industry. Copyright © 2015 Elsevier Ltd.

Betterment, undermining, support and distortion: A heuristic model for the analysis of pressure on evaluators.

Science.gov (United States)

Pleger, Lyn; Sager, Fritz

2016-09-18

Evaluations can only serve as a neutral evidence base for policy decision-making as long as they have not been altered along non-scientific criteria. Studies show that evaluators are repeatedly put under pressure to deliver results in line with given expectations. The study of pressure and influence to misrepresent findings is hence an important research strand for the development of evaluation praxis. A conceptual challenge in the area of evaluation ethics research is the fact that pressure can be not only negative, but also positive. We develop a heuristic model of influence on evaluations that does justice to this ambivalence of influence: the BUSD-model (betterment, undermining, support, distortion). The model is based on the distinction of two dimensions, namely 'explicitness of pressure' and 'direction of influence'. We demonstrate how the model can be applied to understand pressure and offer a practical tool to distinguish positive from negative influence in the form of three so-called differentiators (awareness, accordance, intention). The differentiators comprise a practical component by assisting evaluators who are confronted with influence. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Abstract Background HyperBaric Oxygen (HBO therapy involves exposure to pure oxygen in a pressurized room, and it is an already well-established treatment for various conditions, including those originated by serious infections. Starting from the observation of an increased number of patients who were accessing our HBO units for diseases supported from concomitant multidrug-resistant microorganisms, as well as considering the evident clinical benefit and laboratory final outcome of those patients at the end of the treatment, aim of our study was to measure, or better define at least, if there was any interaction between a hyperbaric environment and some selected microorganisms and if those positive results were due to the increased oxygen partial pressure (pO2 value or just to the increased pressure, regardless of the fraction of inspired oxygen (FiO2 applied (21÷100%. Design and methods We applied various increased pO2 values in a hyperbaric environment. Our study design was tailored in four steps to answer four specific questions, ordered in a progressive process: OxyBioTest (OBT-1,2,3, and 4. Specifically, we chose to investigate possible changes in the Minimum Inhibitory Concentration (MIC and in the Minimum Bactericidal Concentration (MBC of multi-resistant microorganisms after a single session of hyperbaric therapy. Results OBT-1 and OBT-2 provide a semi-quantitative confirmation of the bacterio-cidal and cytostatic effects of HBO. HBO is cidal only if the total exposure pressure is elevated, and cidal or cytostatic effect are not always dependent on the pO2 applied. OBT-4 has shown the adjuvant effect of HBO and antimicrobial drug against some selected bacteria. Discussion We seem allowed to hypothesize that only in case of a good approach to a lesion, permitting smaller bacterial loads thanks to surgical debridement and/or eventual antibiotic therapy for example, You can observe the clear effectiveness of the HyperBaric Oxygen (HBO

Critical review of use of high pressure saturated steam turbine economizers in nuclear power plants

1981-01-01

In the high-pressure part of the turbine drops of moisture condensate, which causes erosion and has negative impact on the service-life of the turbine and on its thermodynamic efficiency. Various designs have been put forward to eliminate moisture. A good combination is moisture separation combined with the offtake of steam for the regeneration of feed water or for the steam re-heater. As concerns the high-pressure component of the turbine it is best to offtake steam for the feed water heater and for heating the steam between the high- and low-pressure components of the turbine. The connections of the heater and re-heater in diagrams of various manufacturers are evaluated and compared. It appears to be uneconomical to use the heater in cases where feed water would be heated to temperature considerably below its optimal value. (M.D.)

Building up a convenient accountability: How the ‘anti-corruption’ law in Brazil was put into force

Directory of Open Access Journals (Sweden)

Fernanda Odilla Vasconcellos de Figueiredo

2016-06-01

Full Text Available This paper focuses on how Brazil designed and put into force a legal instrument that makes companies strictly liable for domestic and international acts of corruption and highlights the role of external drivers during a 15-year process. It also introduces the concept of ‘convenient accountability’ which suggests that Brazil has adopted the slowest and cheaper methods in order to see to demands of those who want and do not want greater accountability in the case of the new clean company act (Law 12846/2013; also dubbed as ‘anti-corruption law’. Despite the apparent force of the civil society in this case of ‘pressure from below’, until now, no company has been punished under Law 12846/2013. An already over-whelmed anti-corruption agency was chosen to enforce the new legislation in the federal and international spheres against companies, some of them being traditional campaign financers and governmental contractors. Hence, it still remains uncertain whether Brazil will effectively enforce its anti-corruption law that, on paper, even exceeds international requirements.

A new type of pressurized piston feeder has been tested for further development of the IGCC concept. The project is funded by the Finnish Ministry of Trade and Industry. The objective has been to develop a substitute for lock-hopper systems, which are commercial, but far too expensive from an operational point of view, due to high inert gas consumption for pressurization. The new feeder system, which is of dual piston type, uses little inert gas, because the pressurization sequence is performed partially by the piston movement. The project comprised further development of the concept, mechanical testing under atmospheric and pressurized conditions and testing with wood chips, peat and coal at elevated pressures. The main concern has been the wear of seals and gaskets during long term operation and for this reason over 600 hours of testing has been carried out. The tests were carried out between May 1994 and January 1995 with wood chips, peat and coal mainly at 17 bar(a) pressure. During the operation, the system was fine-tuned, and generally, the testing was successful. At the early stage of the tests, the ring seal design was modified and several alternative seal constructions were tested. During the tests, the seal was developed further and improved. The present ring seal design has been proven reliable and it meets the commercial requirements. After the tests, the feeder system was inspected thoroughly and found to be in good condition. A commercially available concept of the feeder has been developed on the basis of the knowledge obtained during the test runs

Full Text Available In this paper, we present a new devices brought online thanks to our Collaborative Remote Laboratories framework. Whereas previous devices integrated in our remote laboratory belongs to the domain of electronics, such as Vector Network Analyzers, the devices at the concern in this paper are, on one hand, an antenna workbench, and on the other, an homemade switching device, which embeds several electronic components. Because the middleware and framework for our environment were designed to be reusable, we wanted to put it to the test by integrating new and different devices in our Online Engineering catalog. After presenting the devices to be put online, we will expose the software development efforts required in regards to the reusability of the solution. As a consequence, the expose work and results tend to make the Online Engineering software architects to think reusability first, breaking with the current trends to implement Remote Labs one after the other, without much reusability, apart the capitalized experience. In this, we defend a paradigm switch in our current engineering approaches for Remote Laboratories implementations: Reusability should be thought first.

In this project we mainly prepared and classified several materials, important links for understanding accelerators for different age group. Accelarators now-a-days are very much important tool for not only particle physics laboratories but also for the common people for its extended applications. So, it is very much important to make people know the basics of accelerators, its basic principles, objectives and different varieties. As different age group of people have different level of understandings, so it was necessary to develop materials differently for categories based on age group. Hence, for three different categories we have separately prepared different presentations and collected important all the useful weblinks, videos, animations, games etc. related to accelerators and put them to our new webpage : https://twiki.cern.ch/twiki/bin/view/Main/Material

2011-10-01

Non-invasive positive pressure ventilation (NIPPV) has emerged as a significant advancement in the management of acute hypercapnic respiratory failure. Patients with hypercapnic respiratory failure requiring ventilation therapy (respiratory rate [RR] of > 30 breaths per minutes, PaCO2 > 55 mmHg and arterial pH success group and these parameters continued to improve even after four and 24 hours of NIPPV treatment. Out of 24 (24%) patients who failed to respond, 13 (54%) needed endotracheal intubation within one hour. The failure group had higher baseline HR than the success group. Improvement in HR, RR, pH, and PCO2 one hour after putting the patient on NIPPV predicts success of non-invasive positive pressure ventilation in hypercapnic respiratory failure.

Kang, Kyoung Min; Noh, Sang Woo; Suh, Kune Yull

2009-01-01

The Dual Unit Optimizer 2000 MWe (DUO2000) is put forward as a new design concept for large power nuclear plants to cope with economic and safety challenges facing the 21 st century green and sustainable energy industry. DUO2000 is home to two nuclear steam supply systems (NSSSs) of the Optimized Power Reactor 1000 MWe (OPR1000)-like pressurized water reactor (PWR) in single containment so as to double the capacity of the plant. The idea behind DUO may as well be extended to combining any number of NSSSs of PWRs or pressurized heavy water reactors (PHWRs), or even boiling water reactors (BWRs). Once proven in water reactors, the technology may even be expanded to gas cooled, liquid metal cooled, and molten salt cooled reactors. With its in-vessel retention external reactor vessel cooling (IVR-ERVC) as severe accident management strategy, DUO can not only put the single most querulous PWR safety issue to an end, but also pave the way to very promising large power capacity while dispensing with the huge redesigning cost for Generation III+ nuclear systems. Five prototypes are presented for the DUO2000, and their respective advantages and drawbacks are considered. The strengths include, but are not necessarily limited to, reducing the cost of construction by decreasing the number of containment buildings from two to one, minimizing the cost of NSSS and control systems by sharing between the dual units, and lessening the maintenance cost by uniting the NSSS, just to name the few. The latent threats are discussed as well

Nonalcoholic fatty liver disease (NAFLD) affects 9.6% of children and may put these children at elevated risk of high blood pressure and subsequent cardiovascular morbidity and mortality. Therefore, we sought to determine the prevalence of and risk factors for high blood pressure in children with NAFLD. Cohort study performed by the NIDDK NASH Clinical Research Network. There were 484 children with NAFLD ages 2 to 17 at enrollment; 382 children were assessed both at enrollment and 48 weeks afterwards. The main outcomes were high blood pressure at baseline and persistent high blood pressure at both baseline and 48 weeks. Prevalence of high blood pressure at baseline was 35.8% and prevalence of persistent high blood pressure was 21.4%. Children with high blood pressure were significantly more likely to have worse steatosis than children without high blood pressure (mild 19.8% vs. 34.2%, moderate 35.0% vs. 30.7%, severe 45.2% vs. 35.1%; P = 0.003). Higher body mass index, low-density lipoprotein, and uric acid were independent risk factors for high blood pressure (Odds Ratios: 1.10 per kg/m2, 1.09 per 10 mg/dL, 1.25 per mg/dL, respectively). Compared to boys, girls with NAFLD were significantly more likely to have persistent high blood pressure (28.4% vs.18.9%; P = 0.05). In conclusion, NAFLD is a common clinical problem that places children at substantial risk for high blood pressure, which may often go undiagnosed. Thus blood pressure evaluation, control, and monitoring should be an integral component of the clinical management of children with NAFLD.

In Brazil, as elsewhere, high priority is being given to developing domestic energy sources due to the spectacular increase in the cost of imported petroleum in recent years. This paper discusses the present situation of the thirty-two to thirty-four various Indian areas presently known to be threatened by seven major hydro-electric projects and one flood-control project, either planned or underway, in or directly involving Brazil. A total of at least 100,000 hectares of Indian land (or nearly one hectare for each remaining Brazilian Indian) will be flooded or otherwise expropriated by these projects. Past efforts by the Brazilian National Indian Foundation (FUNAI) to protect the Indians from the pressure of ''national development'' have not been sufficient. Research, planning, publicity, and political pressure are necessary to ensure that their efforts regarding these hydroelectric projects are more successful.

Mainstream preventive interventions often fail to reach poor populations with a high risk of cardiovascular diseases (CVDs) in Pakistan. A community-based CVD primary prevention project aimed at developing approaches to reduce risk factors in such populations was established by Heartfile in collaboration with the National Rural Support Program in the district of Lodhran. The project implemented a range of activities integrated with existing social and health service mechanisms during a three year intervention period 2000/01-03/04. These were targeted in 4 key settings: community health education, mass media interventions, training of health professionals and health education through Lady Health Workers. The project received support from the Department for International Development, U.K. At the community level, a pre-test-post-test quasi-experimental design was used for examining project outcomes related to the community component of the intervention. Pre and post-intervention (training) evaluations were conducted involving all health care providers in randomly selected workshops in order to determine baseline levels of knowledge and the impact of training on knowledge level. In order to assess practices of physician and non-physician health care providers patient interviews, with control comparisons were conducted at each health care facility. Significant positive changes were observed in knowledge levels at a community level in the district of intervention compared with baseline knowledge levels particularly in relation to a heart healthy diet, beneficial level of physical activity, the causes of high blood pressure and heart attack and the effects of high blood pressure and active and passive smoking on health. Significant changes in behaviors at a practice level were not shown in the district of intervention. However the project played a critical role in spurring national action for the prevention and control of non-communicable diseases and introducing

Reviving large-scale projects

For the past decade, most large-scale hydro development projects in northern Quebec have been put on hold due to land disputes with First Nations. Hydroelectric projects have recently been revived following an agreement signed with Aboriginal communities in the province who recognized the need to find new sources of revenue for future generations. Many Cree are working on the project to harness the waters of the Eastmain River located in the middle of their territory. The work involves building an 890 foot long dam, 30 dikes enclosing a 603 square-km reservoir, a spillway, and a power house with 3 generating units with a total capacity of 480 MW of power for start-up in 2007. The project will require the use of 2,400 workers in total. The Cree Construction and Development Company is working on relations between Quebec's 14,000 Crees and the James Bay Energy Corporation, the subsidiary of Hydro-Quebec which is developing the project. Approximately 10 per cent of the $735-million project has been designated for the environmental component. Inspectors ensure that the project complies fully with environmental protection guidelines. Total development costs for Eastmain-1 are in the order of $2 billion of which $735 million will cover work on site and the remainder will cover generating units, transportation and financial charges. Under the treaty known as the Peace of the Braves, signed in February 2002, the Quebec government and Hydro-Quebec will pay the Cree $70 million annually for 50 years for the right to exploit hydro, mining and forest resources within their territory. The project comes at a time when electricity export volumes to the New England states are down due to growth in Quebec's domestic demand. Hydropower is a renewable and non-polluting source of energy that is one of the most acceptable forms of energy where the Kyoto Protocol is concerned. It was emphasized that large-scale hydro-electric projects are needed to provide sufficient energy to meet both

Putting a spin on circulating reference, or how to rediscover the scientific subject.

Kochan, Jeff

2015-02-01

Bruno Latour claims to have shown that a Kantian model of knowledge, which he describes as seeking to unite a disembodied transcendental subject with an inaccessible thing-in-itself, is dramatically falsified by empirical studies of science in action. Instead, Latour puts central emphasis on scientific practice, and replaces this Kantian model with a model of "circulating reference." Unfortunately, Latour's alternative schematic leaves out the scientific subject. I repair this oversight through a simple mechanical procedure. By putting a slight spin on Latour's diagrammatic representation of his theory, I discover a new space for a post-Kantian scientific subject, a subject brilliantly described by Ludwik Fleck. The neglected subjectivities and ceaseless practices of science are thus re-united. Copyright © 2014 Elsevier Ltd. All rights reserved.

Currently, at least 18,000 women die every year in Indonesia due to pregnancy or childbirth. It means that every half hour a woman dies due to pregnancy or childbirth. As a result, every year 36,000 children became orphans. The high maternal mortality rate was put Indonesia on top in ASEAN. The main causes of maternal mortality are high-risk pregnancy. Mothers who have diseases like high blood pressure, pre-eclampsia, diabetes, hyperthyroidism, and already over 40 years old and infectious diseases such as rubella, hepatitis and HIV can be factors that lead to high-risk pregnancy. This paper will discuss the development of a blood pressure monitoring device that is suitable for pregnant women. It is based on convenience for pregnant women to get the equipment that is flexible with her presence. Results indicate that the equipment is in use daily support for pregnant women therefore, one of the causes of maternal mortality can be detected earlier.

The immediate need for a high efficiency, low cost carbon capture process has prompted the recent development of pressurized oxy-combustion. With a greater combustion pressure the dew point of the flue gas is increased, allowing for effective integration of the latent heat of flue gas moisture into the Rankine cycle. This increases the net plant efficiency and reduces costs. A novel, transformational process, named Staged, Pressurized Oxy-Combustion (SPOC), achieves additional step changes in efficiency and cost reduction by significantly reducing the recycle of flue gas. The research and development activities conducted under Phases I and II of this project (FE0009702) include: SPOC power plant cost and performance modeling, CFD-assisted design of pressurized SPOC boilers, theoretical analysis of radiant heat transfer and ash deposition, boiler materials corrosion testing, construction of a 100 kWth POC test facility, and experimental testing. The results of this project have advanced the technology readiness level (TRL) of the SPOC technology from 1 to 5.

This document is the Final Technical Report for a project supported by U.S. DOE NETL (Contract No. DE-FE0000507), GE Global Research, GE Energy, and Idaho National Laboratory (INL). This report discusses key project accomplishments for the period beginning August 7, 2009 and ending December 31, 2012. In this project, pressurized delivery of coal/biomass mixtures using GE Posimetric* solids pump technology was achieved in pilot scale experiments. Coal/biomass mixtures containing 10-50 wt% biomass were fed against pressures of 65-450 psi. Pressure capability increased with decreasing biomass content for a given pump design, and was linked to the interaction of highly compressible coal/biomass mixtures with the pump outlet design. Biomass pretreatment specifications for particle size and moisture content were defined based on bench-scale flowability, compressibility, friction, and permeability experiments that mimic the behavior of the Posimetric pump. A preliminary economic assessment of biomass pretreatment and pump operation for coal/biomass mixtures (CBMs) was conducted.

This report presents the results of a six-month Phase 1 study to establish the state-of-the-art in fiber optic pressure sensing and describes the design and principle of operation of various fiber optic pressure sensors. This study involved a literature review, contact with experts in the field, an industrial survey, a site visit to a fiber optic sensor manufacturer, and laboratory testing of a fiber optic pressure sensor. The laboratory work involved both static and dynamic performance tests. In addition, current requirements for environmental and seismic qualification of sensors for nuclear power plants were reviewed to determine the extent of the qualification tests that fiber optic pressure sensors may have to meet before they can be used in nuclear power plants. This project has concluded that fiber optic pressure sensors are still in the research and development stage and only a few manufacturers exist in the US and abroad which supply suitable fiber optic pressure sensors for industrial applications. Presently, fiber optic pressure sensors are mostly used in special applications for which conventional sensors are not able to meet the requirements

In relation to reactor primary coolant pumps, mechanical seal assembly for a pump shaft is disclosed which features a rotating seal ring mounting system which utilizes a rigid support ring loaded through narrow annular projections in combination with centering non-sealing O-rings which effectively isolate the rotating seal ring from temperature and pressure transients while securely positioning the ring to adjacent parts. A stationary seal ring mounting configuration allows the stationary seal ring freedom of motion to follow shaft axial movement up to 3/4 of an inch and shaft tilt about the pump axis without any change in the hydraulic or pressure loading on the stationary seal ring or its carrier.

2017-01-01

　The effect of the amount of the proline transporter PutP expression on the mechanism of adaptation of E. coli cells to high salinity was analyzed. The PutP gene derived from the E. coli expression plasmid was introduced into the E. coli cell, and a high PutP expression strain was developed. At 1.2 M NaCl culture condition, the growth of normal E. coli cells was inhibited, whereas high ProP expression cells showed growth under 2.5 M NaCl conditions. The uptake of proline by E. coli as a compatible solute and substrate for metabolization was in good accordance with those seen in cell growth. These data suggested that the amount of the proline transporter PutP expression played an important role in the adaptation of E. coli cells to high saline conditions.

Full Text Available Wearable technologies are gaining momentum and widespread diffusion. Thanks to devices such as activity trackers, in form of bracelets, watches, or anklets, the end-users are becoming more and more aware of their daily activity routine, posture, and training and can modify their motor-behavior. Activity trackers are prevalently based on inertial sensors such as accelerometers and gyroscopes. Loads we bear with us and the interface pressure they put on our body also affect posture. A contact interface pressure sensing wearable would be beneficial to complement inertial activity trackers. What is precluding force sensing resistors (FSR to be the next best seller wearable? In this paper, we provide elements to answer this question. We build an FSR based on resistive material (Velostat and printed conductive ink electrodes on polyethylene terephthalate (PET substrate; we test its response to pressure in the range 0–2.7 kPa. We present a state-of-the-art review, filtered by the need to identify technologies adequate for wearables. We conclude that the repeatability is the major issue yet unsolved.

Sasajima, H.

1997-01-01

Since the construction of Japanese first commercial nuclear power plant in 1966, 52 nuclear power plants have been commissioned in Japan to commercial operation. Japanese first nuclear power plant has now been service for 30 years and the aging of nuclear power plants is steadily progressing in general. Under these circumstances, the Japan Power Engineering and Inspection Corporation (JAPEIC) is executing, under consignment by the Ministry of International Trade and Industry (MITI), the development and verification test programs for plant integrity evaluation technology by which nuclear power plant aging can be appropriately handled. This paper shows the outline of study dealing with embrittlement of RPV caused by neutron irradiation, as one of the activity of JAPEIC. The embrittlement of RPV caused by neutron irradiation is manifested as a shift of transition temperature and as a reduction in Upper Shelf Energy (USE). In JAPEIC, the study dealing with a shift of transition temperature was conducted in the ''Reactor Pressure Vessel Pressurized Thermal Shock Test Project (the PTS Project)'', and the study dealing with a reduction in USE has been conducted in the ''Nuclear Power Plant Life Management Technology (the PLIM Project)''. And the reconstitution technology of surveillance test specimen has been conducted in PLIM Project as one of the measures to improve monitoring above material characteristic changes. The integrity evaluation under the Pressurized Thermal Shock (PTS) events including the effect of neutron irradiation embrittlement was initiated in 1983 FY as the PTS Project and was completed in the 1991 FY. The study verified that plant integrity could be assured at not only the end of design life, but also an extended service life even when the severest PTS events were postulated. The PLIM Project, designed to develop and verify the integrity evaluation technology dealing with reduction of USE by neutron irradiation, was started in the 1996 FY as a 10

Design of pressure vessels. Part 1

Grandemange, J.M.

2008-01-01

The equipments and loops of PWR reactors are basically pressure vessels. Their specificities concern the integrity warranties that must be implemented considering their importance for the reactors safety. Thus, stress is put on the exhaustiveness of the prevention of in-service degradation and on the safety scenarios considered. The second specificity concerns the possibility of activation of wear and corrosion products during their flow inside the reactor core. This second aspect leads to some constraints on the choice of the materials used and on the surface coating of the inside wall of big components of the primary circuit. The aim of this document is to develop the general approach adopted for the design of the pressure vessels of PWR fluid loops, and to stress more particularly on the nuclear particularities of these equipments. Some extensions of these rules to high temperature resistant materials (FBR-type reactors) are also evoked. Content: General considerations: design basis of pressure vessels, risk analysis and design conditions, ruining paths and safety coefficients; 2 - damage prevention for excessive deformation: definitions, criteria; 3 - prevention of the plastic instability damage: definition, criteria; 4 - buckling prevention: definition and mechanisms, rules and criteria; 5 - prevention of progressive deformation damage: definitions, plastic adaptation, plastic accommodation, progressive deformation; 6 - prevention of fatigue damage: definitions, general prevention approach, design fatigue curves, analytic approach, particular aspects, analysis of zones with geometrical singularity; 7 - prevention of sudden rupture damage: fragile rupture and ductile tear, general approach, analytic criteria, irradiation and aging effects; 8 - other potential damages; 9 - conclusion.

High hydrostatic pressure is a non-thermal food processing technology, which also has several successful applications in different areas besides food processing. In this study, Capsicum annuum L. (pepper) seeds are subjected to 50, 100, 200 and 300 MPa pressure for 5 min at 25°C and the seedlings of HHP processed seeds are used to compare percentage of seed germination and biochemical properties such as chlorophyll a, b and a/b, proline content, total protein, carotenoid, malondialdehyde, glucose, fructose and phenolic compounds concentrations. As a result of the study, it was observed that there are remarkable changes in terms of biochemical properties especially for seedlings, whose seeds were pressurized at 200 and 300 MPa. More detailed studies are needed to put forward the mechanism behind the changes in biochemical properties.

VAPOR PRESSURES AND HEATS OF VAPORIZATION OF PRIMARY COAL TARS

Energy Technology Data Exchange (ETDEWEB)

Eric M. Suuberg; Vahur Oja

1997-07-01

This project had as its main focus the determination of vapor pressures of coal pyrolysis tars. It involved performing measurements of these vapor pressures and from them, developing vapor pressure correlations suitable for use in advanced pyrolysis models (those models which explicitly account for mass transport limitations). This report is divided into five main chapters. Each chapter is a relatively stand-alone section. Chapter A reviews the general nature of coal tars and gives a summary of existing vapor pressure correlations for coal tars and model compounds. Chapter B summarizes the main experimental approaches for coal tar preparation and characterization which have been used throughout the project. Chapter C is concerned with the selection of the model compounds for coal pyrolysis tars and reviews the data available to us on the vapor pressures of high boiling point aromatic compounds. This chapter also deals with the question of identifying factors that govern the vapor pressures of coal tar model materials and their mixtures. Chapter D covers the vapor pressures and heats of vaporization of primary cellulose tars. Chapter E discusses the results of the main focus of this study. In summary, this work provides improved understanding of the volatility of coal and cellulose pyrolysis tars. It has resulted in new experimentally verified vapor pressure correlations for use in pyrolysis models. Further research on this topic should aim at developing general vapor pressure correlations for all coal tars, based on their molecular weight together with certain specific chemical characteristics i.e. hydroxyl group content.

Marine radioecology. Annual report 1996. Project plan 1997

International Nuclear Information System (INIS)

1997-06-01

The project plan for the EKO-1 project states that 'the main aim of the EKO-1 project is to enable faster and better assessments to be made of the effects of releases of radionuclides into the marine environment'. To meet this goal the main parts of the project were defined as follows: Model work - Identifying parameters of main interest including estimating and validating the values of these parameters; Research - Field studies, environments typical for various Nordic regions, environments with special physical or chemical characteristics. Laboratory studies; Dissemination of information - Seminars, reports, articles. During the project period emphasis has also been put on quality issues concerning sampling and analysis. The project work has progressed in accordance with project plans in 1996 and within the set budget. In modelling a parameter sensitivity analysis was carried out for a radiological assessment model used for the prediction of doses to man from dumping of radioactive waste in the Kara Sea. Doses to man were found to be generally dominated by contributions from long-lived transuranic radionuclides (plutonium and americium) which associate readily with sediments. Sediment related processes and parameters show therefore high sensitivities, especially at long distances (e.g. Barents Sea). Within the EKO-1 project there has been emphasis on encouraging the Nordic aspect of sediment research in spite of the limitations set by nationally run sampling projects. The EKO-1 project has managed this by e.g.: Organizing exchange of samples for analysis links with the EKO-2.3 project ('Limnic systems'). (EG) 52 refs

Putts that get missed on the right: investigating lateralized attentional biases and the nature of putting errors in golf.

Roberts, Ross; Turnbull, Oliver H

2010-02-01

Although the effects of lateral biases in visual attention ("pseudoneglect") have been examined in real-world settings, this phenomenon has yet to be considered within the realm of sporting performance. In the present study, we investigated the effects of pseudoneglect on putting errors in golf. Novice golfers (n = 30) performed 90 putting trials followed by a series of pseudoneglect tasks: requiring participants to bisect lines manually and with a biomechanical bisection tool. All pseudoneglect measures were performed with both the left and right hands. Results demonstrated a leftward bias for all the pseudoneglect tasks, and a rightward bias for putting error. Moreover, the results revealed that individuals who bisected lines to the left on the Bisection Tool (the typical class of pseudoneglect error for humans) with the left hand (the hand that typically produces the greatest pseudoneglect bias) displayed significantly smaller rightward putting errors. Moreover, these individuals also holed more putts. No other pseudoneglect tasks were shown to impact on putting performance. Our findings suggest that lateralized attentional biases have a significant effect on sport performance; they appear to influence a wide range of precision-based sports (e.g. shooting, archery). Findings are also discussed in terms of the processes that are likely to be involved in this effect.

The contribution is focused on Alessandro Antonelli's project for the seat of the new italian parliament in Turin. The project, unrealized, began back in 1860, when the annexation to the Piedmont of Tuscany and the Emilia asked for the building in the capital of a decent seat for the National Parliament. It had to be situated on the area of the ex Carignano garden, behind the homonym building and the "antonellian" Collegio delle Provincie, in the heart of the city, that comes to be as representative place of the absolutist and dynastic power, through the phases of XVIIIth century of amplification and architectural-urbanism new configuration. To deepen therefore the knowledge of Antonelli's project and to understand better the reasons that have brought to the choice to locate in Palazzo Carignano the Italian Parliament, is has been chosen to deepen the relationships between the building and the city, through a punctual iconografic and archivistic documentation that it has allowed to read the development of the building among XVIIth and XIXth century, also in relationship to the urban transformation, putting to comparison the various projects of the contest with the Baroque existence. Through the restitution of virtual images it has been possible to optimize the hypothesis, putting not only to fire the philosophy of the project, but above all Antonelli's way to measure himself with such an incisive existence in the city as the "guariniano" Palazzo Carignano and to bring back the linguistic choice to the amplest circle of the works that the architect realized in the city of Turin.

[Urinary incontinence as a risk factor for pressure sores does not withstand a critical examination].

Science.gov (United States)

Krause, Tom; Anders, Jennifer; von Renteln-Kruse, Wolfgang

2005-10-01

The association between urinary incontinence and pressure sores is put down to various causes. Most frequently urinary wet and following maceration of the skin are mentioned. However, it is possible that urinary incontinence is only an indicator for other risk factors or a measure of the need for care without any causal relation to pressure sores. There are hardly any controlled or randomised studies; this lack of scientific evidence is problematic. Based on a case-control-study including data of 200 patients as well as on the existing models of explanation, the following study tries to examine critically the connections between pressure sores and urinary incontinence. Out of the patients in our study population 97.5 percent were incontinent. Different categories of the risk factor urinary incontinence and different dichotomisations have led to different statistical results. Statements concerning the connection between urinary incontinence and pressure sores have to be interpreted critically. The dependence of urinary incontinence on other risk factors such as patients' need for care or compliance suggests that the causal connection to pressure sores be not reduced to the influence of wetness. We advise to research connections between urinary incontinence and pressure sores in a methodologically appropriate setting.

Full Text Available The aim of this article is to examine how Rudolf Steiner’s anthroposophical ideas were reflected and put into practice in the lives of the Finnish couple Olly (Olga Donner (1881–1956, neé Sinebrychoff and Uno Donner (1872–1958. They encountered anthroposophy in 1913 and subsequently embraced it as the guiding principle of their lives. Through a close examination of these two people we aim to shed light on how a new worldview like anthroposophy, which was gaining followers in early twentieth-century Finland, was also a manifestation of wider changes in religious culture in Europe. Our perspective could be described as biographical in the sense that it has been characterised by Simone Lässig (2008: 11 who writes that ‘the reconstruction of individual life courses helps to discover more about the context – for example, about daily rituals, pious practices, or kinship relationship’. Thus, the biographical perspective serves as a tool for grasping how something as deeply personal as an anthroposophical worldview was understood and practised, not only by Olly and Uno Donner, but also by a larger group of people who in the early twentieth century were looking for new ways to make sense of the surrounding world.

The objective of this project is to obtain basic experimental data on pyrolysis and gasification of various black liquors and biofuels at elevated pressures, and to model these processes. Liquor-to-liquor differences in conversion behavior of single liquor droplets during gasification at atmospheric pressure were investigated. The applicability of a rate equation developed for catalyzed gasification of carbon was investigated with regard to pressurized black liquor gasification. A neural network was developed to simulate the progression of char conversion during pressurized black liquor gasification. Pyrolysis of black liquor in a pressurized drop-tube furnace was investigated in collaboration with KTH in Stockholm. (author)

Fluor-Hanford 3013 Digital Radiography Dead Zone Mitigation Project Pressure Test Report

International Nuclear Information System (INIS)

Gibbs, K.

2003-01-01

The use of digital radiographic (DR) measurement of lid deflection as an indication of pressurization of the 3013 inner can was first reported by the Savannah River Technology Center (SRTC). The conclusions of this report were that for cans with relatively large initial concavity, lid deflection could be used to meet the 3013 standard (DOE-STD-3013-2000) requirement for a nondestructive indication of a pressurization of 100 psig. During acceptance testing of the system in the Spring of 2003, it was confirmed that for some cans the DR measured lid deflection could become insensitive to the change in lid deflection when compared to actual mechanical measurements. The basic explanation of this phenomenon is that characteristics of the lid geometry such as tilt and wobble can obfuscate the bottom of the lid where the deflection is measured. The purpose of this report is to document the results of the pressure testing and the efficacy of the alternate imaging and analysis methods developed to mitigate the dead zone problem. Prior to review of the results, a review of the current method and an introduction to the newly developed methods and techniques is provided

At dawn this morning, the sun went to work for customers of the Sacramento Municipal Utility District (SMUD). The largest photovoltaic (PV) power plant in the world, adjacent to the closed nuclear power plant at Rancho Seco, generated enough electricity for over a thousand customers, rooftop solar water heaters lowered thousands of residential electric bills and rooftop PV systems turned hundreds of Sacramento homes into mini power plants. SMUD, in partnership with their customers-owners, is leading the way in putting the sun to work today. SMUD plans to have at least half of its energy come from energy efficiency, existing hydroelectric plants and renewable resources in this decade. SMUD expects investments made in solar power today to provide its customer-owners with substantial long-term energy, environmental and community benefits. This article describes some of SMUD's efforts

ATLAS, and also the other LHC-experiments, has been very active in this process to maximally influence the outcome. Our main priorities were to ensure that the global aspects are properly taken into account, that the CERN non-member states are also included in the structure, that the experiments are properly involved in the LCGP execution and that the LCGP takes operative responsibility during the data challenges. A Project Launch Board (PLB) was active from the end of July until the 10th of September. It was chaired by Hans Hoffmann and had the IT division leader as secretary. Each experiment had a representative (me for ATLAS), and the large CERN member states were each represented while the smaller were represented as clusters ac...

Launch Velocities in Successful Golf Putting: An Analytical Analysis

Directory of Open Access Journals (Sweden)

John F. Mahoney

2017-04-01

Full Text Available Background: This study is concerned with the special case of a putted ball intersecting a standard golf hole at its diameter. The velocity of the ball at the initial rim of the hole is termed the launch velocity and depending upon its value the ball may either be captured or it may escape capture by jumping over the hole. The critical value of the launch velocity (V is such that lesser values result in capture while greater values produce escape. Purpose: Since the value of the V entered prominently in some theoretical studies of putting, the aim of the current study is to provide an original re-evaluation of V and to contrast our results with existing results. Method: This analytical analysis relies on trigonometry in conjunction with Newtonian mechanics and the mathematics of projectiles. The results of a recent study into the mathematics of a bouncing ball which included the notions of restitution and friction were also employed in the analysis. Results: If bouncing and slipping do not occur when the ball hits the far rim of the hole our analysis produces a value of V of 1.356 m/s. When bouncing and slipping are present we find that V is at least 1.609 m/s but increases beyond this value as slipping and friction become greater. Useful relations which relate the dynamics and geometry of the ball to V are provided. Conclusion: Since ambient conditions may influence the extent of bounce and slippage we conjecture that the value of V is not unique.

Since the late 1990s, financial analysts have focused strongly on short-term profitability for benchmarking and valuation of international oil and gas companies. The increasing pressure for strict capital discipline among oil and gas companies may have reduced their willingness to invest for future reserves and production growth. The current high oil price is partly due to low exploration activity in the oil industry the last decade. We present and discuss the background for this development - based on previous academic research, industry trends and current valuation practices. An estimated econometric model of stock market valuation among oil and gas companies suggests that analysts and companies have put exaggerate weight on short-term earnings and accounting profitability. We therefore expect that the attention will shift back to long-term reserve and production growth. (author)

Report From BPTCS Project Team On Evaluation Of Additive Manufacturing For Pressure Retaining Equipment

Energy Technology Data Exchange (ETDEWEB)

Rawls, G. [Savannah River Site (SRS), Aiken, SC (United States)

2016-09-22

ASME is evaluating the use of additive manufacturing (AM) for the construction of pressure equipment. The information in this report assesses available AM technologies for direct metal fabrication of pressure equipment. Background information is included in the report to provide context for those not experienced in AM technology. Only commercially available technologies for direct metal fabrication are addressed in the report because these AM methods are the only viable approaches for the construction of pressure equipment. Metal AM technologies can produce near-net shape parts by using multiple layers of material from a three dimensional (3D) design model of the geometry. Additive manufacturing of metal components was developed from polymer based rapid prototyping or 3D printing. At the current maturity level, AM application for pressure equipment has the potential to reduce delivery times and costs for complex shapes. AM will also lead to a reduction in the use of high cost materials, since parts can be created with corrosion resistant layers of high alloy material and structural layers of lower cost materials.

The SSDP has been using a Configuration Control system as a significant element in the management plan for the safe and effective performance of the project. The objective of the Configuration Control system is to control the physical plant configuration, system status, work schedules, status tracking, and day-to-day problem resolution. Prior to the Decommissioning Operations Contractor (DOC) assuming operational responsibility for the Shippingport Plant, an assessment was made of the status of the configuration of the systems and related documentation. Action was taken as required to match the operating procedures and system documentation with the actual physical condition of the plant. During the first stage of the project, planning was put in place for subsequent decommissioning activities. This planning included defining organizational responsibilities, completing the necessary project instructions and procedures, and doing the planning and scheduling for the subsequent decommissioning phase activities. Detailed instructions for the performance of the various decommissioning tasks were prepared. Prior to the start of any work on a given Activity Package, a Work Authorization is required. The Work Authorization form provides a complete checklist to ensure that all necessary prerequisites are completed. A computerized Communications Configuration Control Information system monitors status including information on system status, tag-outs, radiological work permits, etc. An ongoing effort is being directed toward maintaining operating instructions and system schematics, etc. current as the Plant configuration changes. The experience with the Configuration Control System to date has been favorable

Individuals with chronic tic disorders (CTDs) frequently describe aversive subjective sensory sensations that precede their tics. The first aim of the present study was to explore the psychometric properties of a standardized self-report measure to assess premonitory urges in CTDs, The Premonitory Urge for Tics Scale (PUTS), by replicating the analyses of Woods et al. (J Dev Behav Pediatr 26:397-403, 2005) using a sample twice the size of theirs. The second aim was to conduct an exploratory factor analysis of the PUTS. Eighty-four youth with CTDs, recruited from a pediatric OCD and tic specialty clinic, completed the PUTS while their caregivers completed The Parent Tic Questionnaire (PTQ) and a demographic measure. Consistent with (Woods et al. J Dev Behav Pediatr 26:397-403, 2005), the PUTS was found to be internally consistent (α = 0.82) and significantly correlated with overall tic severity as measured by the PTQ (r = 0.24, p tics than the frequency or intensity of tics.

Project Politics, Priorities and Participation in Rural Water Schemes

Directory of Open Access Journals (Sweden)

Barbara van Koppen

2012-02-01

Full Text Available Governments, NGOs and financers invest considerable resources in rural domestic water supplies and irrigation development. However, elite capture and underuse, if not complete abandonment, are frequent. While the blame is often put on 'corrupt, lazy and indisciplined' communities, this article explores the question of how the public water sector itself contributes to this state of affairs. Four case studies, which are part of the research project Cooperation and Conflict in Local Water Governance, are examined: two domestic water supply projects (Mali, Vietnam; one participatory multiple use project (Zambia; and one large-scale irrigation project (Bolivia. It was found that accountability of water projects was upward and tended to lie in construction targets for single uses with already allocated funding. This rendered project implementers dependent upon the village elite for timely spending. Yet, the elite appeared hardly motivated to maintain communal schemes, unless they themselves benefited. The dependency of projects on the elite can be reduced by ensuring participatory and inclusive planning that meets the project’s conditions before budget allocation. Although such approaches are common outside the water sector, a barrier in the water sector is that central public funds are negotiated by each sector by profiling unique expertise and single livelihood goals, which trickle down as single use silos. The article concludes with reflections on plausible benefits of participatory multiple use services for equity and sustainability.

Ambulatory Blood Pressure Monitoring for the Effective Management of Antihypertensive Drug Treatment.

Science.gov (United States)

O'Brien, Eoin; Dolan, Eamon

2016-10-01

This purpose of this article is to review the current recommendations for ambulatory blood pressure measurement (ABPM) and the use of ABPM in assessing treatment. We review current international guidelines and undertake a critical review of evidence supporting the clinical use of ABPM in effectively managing antihypertensive drug treatment. Current guidelines emphasize the diagnostic superiority of ABPM, mainly from the ability of the technique to identify sustained hypertension by allowing for the exclusion of white-coat hypertension and by demonstrating the presence of masked hypertension. ABPM also offers diagnostic insights into nocturnal patterns of blood pressure, such as dipping and nondipping, reverse dipping, and excessive dipping, and the presence of nocturnal hypertension; although less attention is given to the nocturnal behavior of blood pressure in clinical practice, the nocturnal patterns of blood pressure have particular relevance in assessing the response to blood pressure-lowering medication. Surprisingly, although the current guidelines give detailed recommendations on the diagnostic potential and use of ABPM, there are scant recommendations on the benefits and application of the technique for the initiation of blood pressure-lowering therapy in clinical practice and virtually no recommendations on how it might be used to assess the efficacy of drug treatment. In view of a deficiency in the literature on the role of ABPM in assess the efficacy of drug treatment, we put forward proposals to correct this deficiency and guide the prescribing physician on the most appropriate drug administration and dosage over time.

Task transfer: another pressure for evolution of the medical profession.

Science.gov (United States)

Van Der Weyden, Martin B

2006-07-03

Since the 1960s, Australian society and the medical profession have undergone enormous change. Our society has moved from a relatively homogeneous and conservative community, supported by limited government services, to one that is multicultural, focused on the individual and consumerism, and supported by extensive government programs, with health care a top public and political priority. A defining feature of contemporary society is its mistrust of institutions, professionals, public servants and politicians. The medical profession has changed from a cohesive entity, valuing generalism and with limited specialisation, to one splintered by ultra-specialisation and competing professional agendas. The medical workforce shortage and efforts to maintain the safety and quality of health services are putting acute pressure on the profession. Task transfer or role substitution of medical services is mooted as a potential solution to this pressure. This has the potential to drastically transform the profession. How task transfer will evolve and change medicine depends on the vision and leadership of the profession and a flexible pragmatism that safeguards quality and safety and places patient priorities above those of the profession.

At present, the major part of the discussion does not focus on technical assessment methodology and data, but rather on interpretation of the available geologic data for high-level waste disposal planning. Meanwhile, plans for the implementation of repositories have to be developed. Accordingly, the longer-term studies on high-level waste disposal are proceeding at a pace appropriate for their relatively far-future timescales, and intensified efforts are being put into projects for design, siting, safety assessment and construction of the more urgently required repository for low and intermediate level waste.

A molecular dynamics investigation of the surface tension of water nanodroplets and a new technique for local pressure determination through density correlation

Science.gov (United States)

Leong, Kai-Yang; Wang, Feng

2018-04-01

The surface tension of nanoscale droplets of water was studied with molecular dynamics simulations using the BLYPSP-4F water potential. The internal pressure of the droplet was measured using an empirical correlation between the pressure and density, established through a series of bulk simulations performed at pressures from 1 to 1000 bars. Such a procedure allows for reliable determination of internal pressure without the need to calculate the local virial. The surface tension, estimated with the Young-Laplace relation, shows good agreement with the Tolman equation with a Tolman length of -0.48 Å. The interface of a liquid water droplet is shown to be around 1.1-1.3 nm thick depending on radii. The fairly thick interface region puts a lower limit on the size of droplets that still have a bulk-like interior.

Pressure distribution due to steam bubble collapse in a BWR suppression chamber

International Nuclear Information System (INIS)

Giencke, E.

1979-01-01

For the pressure time history at the walls of a suppression chamber due to a steam bubble collaps at the condenser pipes interests, expecially the influence of the wall elasticity and the position of the condenser pipes. Two problems are to solve: the pressure time history in the steam bubble and at the walls during the collaps and the pressure distribution at the walls. Both problems are coupled with each other, but the influence of the wall elasticity on the pressure time history in the steam bubble is usually small. Thus the two problems may be solved one after each other. For simplifying the analysis the steam bubble surface may be idealized as a sphere during the whole collaps time. Then the resulting pressure time history is be put on the fluid-structure-system. To show the influence of the containment-elasticity it is favourable to investigate both the rigid and the elastic containment. Because the condenser pipes are arranged in a regular scheme, two limit loading cases are to distinguish. Collapses occur simultaneously with the same intensity at all condenser pipes and a strong collaps occurs only at one condenser pipe or a small group of pipes. When including wall elasticity first the modes of the fluid-structure-system are to analyse and then the dynamical responses of the modes. The coupling effects between the pressure time history in the bubble and at the walls are discussed and then how the membrane and bending stiffness of the walls and the buttomstructure influence the pressure distribution, both for steel and concrete structure. Finally simple models for the analysis are derived and the analytical results are compared with experiments. (orig.)

Improving the attractiveness of CDM projects through allowing and incorporating options

International Nuclear Information System (INIS)

Carmichael, David G.; Ballouz, Joseph J.; Balatbat, Maria C.A.

2015-01-01

The paper puts forward a proposal that, within Clean Development Mechanism (CDM) projects, investors be allowed to benefit from options; this will require a CDM rule change. Through the presence of options, the downside risk resulting from low carbon prices and/or low achieved emission reductions on projects can be limited, while any upside resulting from high carbon prices and/or high achieved emission reductions can be taken advantage of. It is demonstrated that the presence of options improves the financial attractiveness of CDM projects, and this is at no detriment to any stakeholder. The flow-on from the proposal is that more CDM projects should be realisable if options are available, and this in turn will lead to reduced global emissions and improved sustainability. The proposal is supported by the necessary theory and is demonstrated on two registered CDM projects, one on hydropower and one on wind power. - Highlights: • The paper proposes that options be allowed within CDM projects. • Introducing options will require a CDM rule change. • Options improve the financial attractiveness of CDM projects. • Allowing options comes at no cost or detriment to any party. • Allowing options is a win–win situation to both society and the project proponent.

2004-07-01

The Wavegen Project which set out to develop a floating externally tensioned articulated wave-energy generator based on work carried out at RMCS Shrivenham in the 1980s has been abandoned until further notice. The computer modelling carried out in the early days indicated much promise, but the promise turned to disappointment when difficulties cropped-up in attempting to put the design into practice. A particular problem arose in matching the external tension to an equivalent beam stiffness to tune the natural bending frequency of the raft to that of the driving waves. A further eleven practical problems encountered are discussed.

Vulnerability of sandy coasts to climate change and anthropic pressures: methodology and preliminary results

Science.gov (United States)

Idier, D.; Poumadère, M.; Vinchon, C.; Romieu, E.; Oliveros, C.

2009-04-01

1-INTRODUCTION Climate change is considered in the latest reports of the Intergovernmental Panel on Climate Change IPCC (2007) as unequivocal. Induced vulnerability of the system is defined as "the combination of sensitivity to climatic variations, probability of adverse effects, and adaptive capacity". Substantial methodological challenges remain, in particular estimating the risk of adverse climate change impacts and interpreting relative vulnerability across diverse situations. As stated by the IPCC, the "coastal systems should be considered vulnerable to changes in climate". In these areas, amongst the most serious impacts of sea-level rise (Nicholls, 1996) are erosion and marine inundation. Thus, the coast of metropolitan France, being composed of 31% sandy coasts, is potentially vulnerable, as it has been qualitatively assessed on the pilot coasts of Aquitaine and Languedoc-Roussillon in the RESPONSE project (Vinchon et al., 2008). Within the ANR VULSACO project (VULnerability of SAndy COast to climate change and anthropic pressure), the present day erosion tendencies as well as the potentially future erosion trends are investigated. The main objectives are to: (1) assess indicators of vulnerability to climate change for low-lying linear sandy coastal systems, from the shore to the hinterland, facing undergoing climate change and anthropic pressure until the 2030s; and (2) identify the aggravating or improving effect of human pressure on this vulnerability. This second issue is sometimes considered as a main driver of coastal risks. The methodology proposed in the project considers anthropic adaptation (or not) by putting decision makers in front of potential modifications of the physical system, to study the decision process and the choice of adaptation (or not). The coastal system is defined by its morphology, its physical characteristics and its land use. The time scales will range from short-term (days to weeks, e.g. time scale of extreme events) to

Breathing circuit compliance and accuracy of displayed tidal volume during pressure-controlled ventilation of infants: A quality improvement project.

Glenski, Todd A; Diehl, Carrie; Clopton, Rachel G; Friesen, Robert H

2017-09-01

Anesthesia machines have evolved to deliver desired tidal volumes more accurately by measuring breathing circuit compliance during a preuse self-test and then incorporating the compliance value when calculating expired tidal volume. The initial compliance value is utilized in tidal volume calculation regardless of whether the actual compliance of the breathing circuit changes during a case, as happens when corrugated circuit tubing is manually expanded after the preuse self-test but before patient use. We noticed that the anesthesia machine preuse self-test was usually performed on nonexpanded pediatric circuit tubing, and then the breathing circuit was subsequently expanded for clinical use. We aimed to demonstrate that performing the preuse self-test in that manner could lead to incorrectly displayed tidal volume on the anesthesia machine monitor. The goal of this quality improvement project was to change the usual practice and improve the accuracy of displayed tidal volume in infants undergoing general anesthesia. There were four stages of the project: (i) gathering baseline data about the performance of the preuse self-test and using infant and adult test lungs to measure discrepancies of displayed tidal volumes when breathing circuit compliance was changed after the initial preuse self-test; (ii) gathering clinical data during pressure-controlled ventilation comparing anesthesia machine displayed tidal volume with actual spirometry tidal volume in patients less than 10 kg before (machine preuse self-test performed while the breathing circuit was nonexpanded) and after an intervention (machine preuse self-test performed after the breathing circuit was fully expanded); (iii) performing department-wide education to help implement practice change; (iv) gathering postintervention data to determine the prevalence of proper machine preuse self-test. At constant pressure-controlled ventilation through fully expanded circuit tubing, displayed tidal volume was 83

The University of applied sciences HTA Lucerne designed a prototype of an uninterruptible power supply (UPS) with Fuel Cell technology instead of lead-acid batteries and put it into operation. The delayed start-up of the Fuel Cell was bridged with ultra capacitor technology. In a first project stage the system was designed, assembled and tested in laboratory. In a second stage the installation was connected to a real base station of a telecommunication antenna and put to field tests for one year. The field test included monthly simulations of power failure with antenna load of about 2.4 kW as well as tests with external load up to 8.5 kW to establish the characteristic diagram. Hydrogen was provided by two 50 l pressure tanks. The full quantity of hydrogen secured a stand-alone operation of the Fuel Cell system for about 6 hours under antenna load. The results of the 101 grid-failure simulations demonstrate a very reliable start-up behaviour of the Fuel Cell System. Also during a real power failure due to a thunderstorm the installation provided the demanded power without any problem. The total duration of operation of the Fuel Cell during the field tests was 39 hours. No degradation could be noticed. The project takes place in collaboration with the industrial partners APC Industrial Systems, as a producer and market leader of UPS-Systems, and Swisscom Mobile AG, as a user of UPS-systems in telecommunications. Following the good results and in order to get more experience in long-term operation of the Fuel Cell system the tests will go on for two more years. (author)

Evaluation of negative pressure vacuum-assisted system in acute and chronic wounds closure: our experience.

Science.gov (United States)

Chiummariello, S; Guarro, G; Pica, A; Alfano, C

2012-10-01

Negative-pressure therapy or vacuum-assisted closure (VAC) has been used in clinical applications since the 1940's and has increased in popularity over the past decade. This dressing technique consists of an open cell foam dressing put into the wound cavity, a vacuum pump produces a negative pressure and an adhesive drape. A controlled sub atmospheric pressure from 75 to 150 mmHg is applied. The vacuum-assisted closure has been applied by many clinicians to chronic wounds in humans; however it cannot be used as a replacement for surgical debridement. The initial treatment for every contaminated wound should be the necrosectomy. The VAC therapy has a complementary function and the range of its indications includes pressure sores, stasis ulcers, chronic wounds such as diabetic foot ulcers, post traumatic and post operative wounds, infected wounds such as necrotizing fasciitis or sternal wounds, soft-tissue injuries, bone exposed injuries, abdominal open wounds and for securing a skin graft. We describe our experience with the VAC dressing used to manage acute and chronic wounds in a series of 135 patients, with excellent results together with satisfaction of the patients.

The genetic and phenotypic variability of interspecific hybrid bermudagrasses (Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt-Davy) used on golf course putting greens.

2016-10-01

Some interspecific hybrid bermudagrass cultivars used on golf course putting greens are genetically unstable, which has caused phenotypically different off-type grasses to occur in production nurseries and putting surfaces. Management practices to reduce the occurrence of off-type grasses in putting green surfaces and the effect they can have on putting quality and performance need to be researched until genetically stable cultivars are developed. Golf course putting green surfaces in subtropical and tropical climates are typically planted with an interspecific hybrid bermudagrass (Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt-Davy), because of the superior putting quality and performance of these cultivars. 'Tifgreen' was one of the first interspecific hybrids developed for putting green use in lieu of common bermudagrass. However, off-type grasses began appearing in established Tifgreen stands soon after commercial release. Off-type grasses are those with different morphology and performance when compared to the surrounding, desirable cultivar. Off-types have the potential to decrease surface uniformity, which negatively affects putting surface quality. However, several unique off-types from Tifgreen have been selected as commercial cultivars, the first being 'Tifdwarf'; then 'Floradwarf', 'MS-Supreme', 'Pee Dee-102', and 'TL-2', identified later. The cultivars 'Champion Dwarf', 'P-18', 'RJT', and 'Emerald Dwarf' were subsequently selected as off-types in Tifdwarf. The naturally occurring off-types and cultivars that have been identified within the Tifgreen family have widely differing phenotypes; however, they are reported to be genetically similar, supporting the hypothesis that their occurrence is a result of somatic mutations. Genetic instability in currently available commercial cultivars is likely to lead to the continued presence of off-types in production nurseries and putting greens. Additional research is needed to understand the nature of

The objective of the project has been to study barriers for a production of advanced high pressure containers especially suitable for hydrogen, in order to create a basis for a container production in Denmark. The project has primarily focused on future Danish need for hydrogen storage in the MWh area. One task has been to examine requirement specifications for pressure tanks that can be expected in connection with these stores. Six potential storage needs have been identified: (1) Buffer in connection with start-up/regulation on the power grid. (2) Hydrogen and oxygen production. (3) Buffer store in connection with VEnzin vision. (4) Storage tanks on hydrogen filling stations. (5) Hydrogen for the transport sector from 1 TWh surplus power. (6) Tanker transport of hydrogen. Requirements for pressure containers for the above mentioned use have been examined. The connection between stored energy amount, pressure and volume compared to liquid hydrogen and oil has been stated in tables. As starting point for production technological considerations and economic calculations of various container concepts, an estimation of laminate thickness in glass-fibre reinforced containers with different diameters and design print has been made, for a 'pure' fibre composite container and a metal/fibre composite container respectively.

South Stream Project and the Ukrainian Factor

Full Text Available The paper seeks to develop an analysis of the South Stream project in view of the Ukrainian crisis. We cannot put aside the internal factor as Ukraine is facing serious internal issues such as corruption and instability, therefore Russia’s invasion of Ukraine can not be simply ignored in this pipeline project. The article uses mostly facts that happened throughout last years, as well as for and against declarations in the case of the South Stream project and its mother Russia. When we hear about South Stream, we think of Russia and since 2007, this pipeline has encouraged Putin’s faith in energy superpower. A good point to start with was to gather all declarations since then and cover all actions that regard the South Stream game. In Russian foreign policy for the South Stream race, Soft Power was used more than enough and it has recently made room for Hard Power, which is the Ukraine never ending episode. Insights of the South Stream story have been lately related both softly and hardly, this is the reason why I have chosen to analyse both sides in order to complete the energy landscape.

The public's awareness of industrial projects is constantly growing. In addition, if such project imply any sort of environmental impact, their awareness increases and may result in a series of deterrents to the start-up of the said projects. The present article focuses on one of the most powerful of management tools through, at the same time, the one most often forgotten by companies: external communication. In the first part of the article, we shall analyse the reasons why many industrial projects never actually see the light of day. Starting from three working hypotheses, we came to the conclusion that we must be proactive in our communication if we wish our development to be durable and to last. In the second part, we put forward a method for planning communication aimed at first of all, foreseeing, and, ultimately, solving situations arising from the deterrents already mentioned. We have used a classical planning model from which to develop a specific application called Environmental Communication. (Author)

economically stressed. The primary reason for this is the recent fundamental shift in the US energy landscape. Abundant supplies of natural gas have put downward pressure on any project that displaces natural gas or natural gas substitutes. Moreover, this shift appears long-term as domestic supplies for natural gas may have been increased for several hundred years. While electricity prices are less affected by natural gas prices than other thermal projects, they are still significantly affected since much of the power in the Entergy cost structure is driven by natural gas-fired generation. Consequently, rates reimbursed by the power company based on their avoided cost structure also face downward pressure over the near and intermediate term. In addition, there has been decreasing emphasis on environmental concerns regarding the production of thermal energy, and as a result both the voluntary and mandatory markets that drive green attribute prices have softened significantly over the past couple of years. Please note that energy markets are constantly changing due to fundamental supply and demand forces, as well as from external forces such as regulations and environmental concerns. At any point in the future, the outlook for energy prices may change and could deem either the electricity generation or pipeline injection project more feasible. This report is intended to serve as the primary background document for subsequent decisions made at Parish staff and governing board levels.

Two severe accident research projects: 'Severe Accident Management' (VAHTI), 1994-96 and 'Reactor Accidents' Phenomena and Simulation (ROIMA) 1997-98. have been conducted at VTT Energy within the RETU research programme. The main objective was to assist the severe accident management programmes of the Finnish nuclear power plants. The projects had several subtopics. These included thermal hydraulic validation of the APROS code, studies of failure mode of the BWR pressure vessel, investigation of core melt progression within a BWR pressure vessel, containment phenomena, development of a computerised severe accident training tool, and aerosol behaviour experiments. The last topic is summarised by another paper in the seminar. The projects have met the objectives set at the project commencement. Calculation tools have been developed and validated suitable for analyses of questions specific for the Finnish plants. Experimental fission product data have been produced that can be used to validate containment aerosol codes. The tools and results have been utilised in plant assessments. One of the main achievements has been the computer code PASULA for analysis of interactions between core melt and pressure vessel. The code has been applied to pressure vessel penetration analysis. The results have shown the importance of the nozzle construction. Modelling possibilities have recently improved by addition of a creep and porous debris models. Cooling of a degraded BWR core has been systematically studied as joint Nordic projects with a set of severe accident codes. Estimates for coolable conditions have been provided. Recriticality due to reflooding of a damaged core has been evaluated. (orig.)

Tidd PFBC demonstration project

1997-12-31

The Tidd project was one of the first joint government-industry ventures to be approved by the US Department of Energy (DOE) in its Clean Coal Technology Program. In March 1987, DOE signed an agreement with the Ohio Power Company, a subsidiary of American Electric Power, to refurbish the then-idle Tidd plant on the banks of the Ohio River with advanced pressurized fluidized bed technology. Testing ended after 49 months of operation, 100 individual tests, and the generation of more than 500,000 megawatt-hours of electricity. The demonstration plant has met its objectives. The project showed that more than 95 percent of sulfur dioxide pollutants could be removed inside the advanced boiler using the advanced combustion technology, giving future power plants an attractive alternative to expensive, add-on scrubber technology. In addition to its sulfur removal effectiveness, the plant`s sustained periods of steady-state operation boosted its availability significantly above design projections, heightening confidence that pressurized fluidized bed technology will be a reliable, baseload technology for future power plants. The technology also controlled the release of nitrogen oxides to levels well below the allowable limits set by federal air quality standards. It also produced a dry waste product that is much easier to handle than wastes from conventional power plants and will likely have commercial value when produced by future power plants.

Deepwater sediments are prone to loss circulation in drilling due to a low overburden gradient. How to predict the magnitude of leak-off pressure more accurately is an important issue in the protection of drilling safety and the reduction of drilling cost in deep water. Starting from the mechanical properties of a shallow formation and based on the basic theory of rock-soil mechanics, the stress distribution around a borehole was analyzed. It was found that the rock or soil on a borehole is in the plastic yield state before the effective tensile stress is generated, and the effective tangential and vertical stresses increase as the drilling fluid density increases; thus, tensile failure will not occur on the borehole wall. Based on the results of stress calculation, two mechanisms and leak-off pressure prediction models for shallow sediments in deepwater drilling were put forward, and the calculated values of these models were compared with the measured value of shallow leak-off pressure in actual drilling. The results show that the MHPS (minimum horizontal principle stress) model and the FIF (fracturing in formation) model can predict the lower and upper limits of leak-off pressure. The PLC (permeable lost circulation) model can comprehensively analyze the factors influencing permeable leakage and provide a theoretical basis for leak-off prevention and plugging in deepwater drilling.

The SOLA-LOOP computer code for transient, nonequilibrium, two-phase flows in networks has been coupled with a simple valve model to analyze a feedwater pipe breakage with a back-pressure check valve. Three tests from the Superheated Steam Reactor Safety Program Project (PHDR) at Kahl, West Germany, are analyzed, and the calculated transient back-pressure check valve behavior and fluid dynamics effects are found to be in excellent agreement with the experimentally measured data

Comparison of selected approaches to finance renewable energy projects in European countries

A large number of proven technical solutions exists for the use of renewable energies. However, their dissemination is still too slow to meet the political goal of substituting for 8-15% of the primary energy demand in the European Union by the year 2010. Even renewable energy systems (RES) with an economic potential are only partly exploited. The FIRE research project financed partly in the JOULE program analyses and compares the means of financing RES in Austria, Denmark, Germany, the Netherlands, Spain, Sweden and the United Kingdom to put forward best practice recommendations so that renewable energy depolyments will occur at a faster rate. FIRE addresses to politicians, to potential investors and to project-developers. (orig./RHM)

Managing IT Projects in Public Companies: A Case Study

Bouras, A.

2014-07-01

Full Text Available As part of its public sector modernization effort, a North African government has put a lot of effort and allocated significant budgets since 1997 to modernize one of its main public sector companies. Consequently, this company, that mainly offers postal services, initiated many IT-based projects to computerize all paper-based ongoing services offered through its branches and to present new products to customers. This company was aiming to improve service quality and to diversify the range of its services. However, some of these IT-based projects inevitably faced problems. Some projects were either not completed successfully, cancelled, over-budget or taking more time than scheduled. As a result, many employees and customers of this company were dissatisfied and complained about bad planning, slowness and significant disruptions in these projects, an event that affected adversely the quality of service. This study aims at determining the causes of these project disruptions, failures or delays. To achieve this aim, 30 experienced project developers and engineers working in that company’s IT department volunteered to respond to a detailed questionnaire specifically developed for this purpose. The questionnaire included questions about project vision clarity, time/cost management, project quality assurance, risk management and human resources management. Results show that the main reasons for disruptions, failure or delays in IT projects are lack of business plan and poor documentation during and after finishing projects, lack of clear quality assurance criteria, standards and reviews, and poor project risk management practices. Ramifications of such results in terms of improving IT project management practices in the public service sector are finally presented.

Belgoprocess is momentarily in the process of purchasing its fifth NDA-system. Measurement systems are, although based on general designs, not from the shelf items but tailor-made sophisticated and highly automated devices. It is obvious that such a project cannot be carried out by solely a NDA team, but needs a multifunctional team. This team combines NDA expertise with experts in civil works, electrical and mechanical engineering, procurement, IT, safety and legal administration. From less positive experiences in the past, Belgoprocess learned a lot and has now a systematic in place. This systematic structures the project from definition of requirements to operation, a two to three year process. This paper defines the phases of a NDA project and gives for each phase some do's and don'ts. A second subject is the writing and handling of the vast but needed and required documentation. It gives a brief overview of the over thirty documents and files needed. The described, integrated and formal approach reduces the risk of failing projects, systems not meeting the expectations or denied qualification. It puts clear agreements in place, smoothening the relationship between company, supplier and authorities. (authors)

2017-04-01

The 42-month ¡VAMOS! project (Viable Alternative Mine Operating System, Grant Agreement 642477, www.vamos-project.eu), funded by the EC H2020 Programme, will enable access to high-grade EU reserves of mineral ore-bodies by developing an innovative clean and low visibility mining technique. The project will demonstrate the technological and economic viability of the underwater extraction of metallic mineral deposits which are currently technologically, economically, and environmentally unobtainable. In doing so, ¡VAMOS! hopes to encourage investment in abandoned open-pit mines and prospective mines, helping to put the EU back on a level playing field with the rest of the world in terms of access to strategically important minerals. The ¡VAMOS! concept is defined by a remotely-operated underwater mining vehicle, adapted and improved from existing subsea mining technology. Operating in tandem with an HROV, the mining vehicle will connect to a flexible riser through which slurried mined material will be pumped from the mudline to onshore dewatering facilities via a floating mobile deployment-module, on which will be fitted a bypass system linked to an LIBS, allowing real-time grade-control. Analysis of European and national regulation and stakeholder assessments found there is significant support for developing the technology among local communities and governments. An initial environmental assessment of the potential impact of the innovative mining operation concluded the project has a smaller environmental footprint than conventional mining operations: this is due to factors including the quieter operation and absence of blasting, zero water-table flux, and the higher stripping ratio enabled by higher fluid pressure acting on the sidewalls of the mine. The prototypes are currently in their construction phase following a final design freeze in October 2016. Work is now underway on the foresight visioning, economic evaluation and policy guidelines for the �

The objective of this research is to set up the basic technologies for the evaluation of pressure tube integrity and to develop improved zirconium alloys to prevent pressure tube failures due to DHC and hydride blister caused by excessive creep-down of pressure tubes. The experimental procedure and facilities for characterization of pressure tubes were developed. The basic research related to a better understanding of the in-reactor performances of pressure tubes leads to noticeable findings for the first time : the microstructural effect on corrosion and hydrogen pick-up behavior of Zr-2.5Nb pressure tubes, texture effect on strength and DHC resistance and enhanced recrystallization by Fe in zirconium alloys and etc. Analytical methodology for the assessment of pressure tubes with surface flaws was set up. A joint research is being under way with AECL to determine the fracture toughness of O-8 at the EOL (End of Life) that had been quadruple melted and was taken out of the Wolsung Unit-1 after 10 year operation. In addition, pressure tube with texture controlled is being made along with VNINM in Russia as a joint project between KAERI and Russia. Finally, we succeeded in developing 4 different kinds of zirconium alloys with better corrosion resistance, low hydrogen pickup fraction and higher creep strength.

Full Text Available This paper presents an eye gaze controlled projected display that can be used in aviation and automotive environment as a head up display. We have presented details of the hardware and software used in developing the display and an algorithm to improve performance of point and selection tasks in eye gaze controlled graphical user interface. The algorithm does not require changing layout of an interface; it rather puts a set of hotspots on clickable targets using a Simulated Annealing algorithm. Four user studies involving driving and flight simulators have found that the proposed projected display can improve driving and flying performance and significantly reduce pointing and selection times for secondary mission control tasks compared to existing interaction systems.

Industrial-scale injection of CO2 into the subsurface can cause reservoir pressure increases that must be properly controlled to prevent any potential environmental impact. Excessive pressure buildup in reservoir may result in ground water contamination stemming from leakage through conductive pathways, such as improperly plugged abandoned wells or distant faults, and the potential for fault reactivation and possibly seal breaching. Brine extraction is a viable approach for managing formation pressure, effective stress, and plume movement during industrial-scale CO2 injection projects. The main objectives of this study are to investigate suitable different pressure management strategies involving active brine extraction and passive pressure relief wells. Adaptive optimized management of CO2 storage projects utilizes the advanced automated optimization algorithms and suitable process models. The adaptive management integrates monitoring, forward modeling, inversion modeling and optimization through an iterative process. In this study, we employ an adaptive framework to understand primarily the effects of initial site characterization and frequency of the model update (calibration) and optimization calculations for controlling extraction rates based on the monitoring data on the accuracy and the success of the management without violating pressure buildup constraints in the subsurface reservoir system. We will present results of applying the adaptive framework to test appropriateness of different management strategies for a realistic field injection project.

Stanovich's arguments against the "adaptive rationality" project: An assessment.

Science.gov (United States)

Polonioli, Andrea

2015-02-01

This paper discusses Stanovich's appeal to individual differences in reasoning and decision-making to undermine the "adaptive rationality" project put forth by Gigerenzer and his co-workers. I discuss two different arguments based on Stanovich's research. First, heterogeneity in the use of heuristics seems to be at odds with the adaptationist background of the project. Second, the existence of correlations between cognitive ability and susceptibility to cognitive bias suggests that the "standard picture of rationality" (Stein, 1996, 4) is normatively adequate. I argue that, as matters stand, none of the arguments can be seen as fully compelling. Nevertheless, my discussion is not only critical of Stanovich's research, as I also show that (and how) his research can push forward the so-called "rationality debate" by encouraging greater theoretical and experimental work.

Mass optimization of a small pressure vessel using metal/FRP (fiber reinforced polymers) hybrid structures

International Nuclear Information System (INIS)

Nisar, J.A.; Abdullah, A.N.; Iqbal, N.

2004-01-01

In hybrid pressure vessels, composite (Fiber) is wound over a metallic liner (Steel/Aluminum) in hoop direction. In this concept of hybrid pressure vessel structure, metallic liner takes all the axial loads and fiber reinforced polymers (FRP/sub s/) takes load in circumferential (Hoop) direction. Hybrid structures combine the relatively high shear stiffness and ductility of metal alloy with high specific stiffness, strength and fatigue properties of FRP/sub s/. The relatively simple methods for producing hybrid structures circumvent the need for the complex and expensive equipment that is used for advanced composites processing. This paper presents an efficient way of designing a hybrid pressure vessel where prime concern is weight reduction over an equivalent aluminum structure and investigates various methodologies regarding combinations of metals and FRP/sub s/ for optimization of a given pressure vessel. For this purpose we adopted two different methods of simulation one is computer simulation using ANSYS and other is experimental verification by hydrostatic testing of manufactured pressure vessel. Two different pressure vessels one with aluminum liner and other with steel liner were fabricated. Kevlar 49/epoxy was wrapped around the liners in hoop direction. Both the pressure vessels were put into hydrostatic test. Strains were measured during the test and then converted into corresponding stresses. Results of hydrostatic test were quite in favor of the ANSYS results. In this way we have successfully designed, manufactured and tested the Hybrid pressure vessel saving almost 40% weight in case of aluminum liner and 43.6% in case of steel liner. (author)

Risk profile modification of energy projects

Larson, B.O.

1992-01-01

The commodity futures and swaps markets are thought by some to be the invention of speculators, the bane of the oil business, or possibly something confined to finance departments of major corporations. In actuality, they should be considered more as insurance and can be utilized at the project level to modify the risk profile of a property. In this context, an increased familiarity with them can be useful for an engineer. This paper reports that either futures or swaps can be used to guarantee or modify product prices, an accomplishment very difficult or impossible to duplicate through other means, particularly with such integrity. Participation in futures or swaps does not necessarily maximize cashflow or present worth, it can either guarantee the price, put a minimum price in place or offer a combination of the above. A project or company can be protected for several years from downside price risk using swaps. Not being subject to market price swings substantially reduces the risk of the venture. This can be particularly important if lower product prices would cause unacceptable cashflows or net incomes

Cryogenic and Gas System Piping Pressure Tests (A Collection of PT Permits)

Rucinski, Russell A.

2002-01-01

This engineering note is a collection of pipe pressure testing documents for various sections of piping for the D-Zero cryogenic and gas systems. High pressure piping must conform with FESHM chapter 5031.1. Piping lines with ratings greater than 150 psig have a pressure test done before the line is put into service. These tests require the use of pressure testing permits. It is my intent that all pressure piping over which my group has responsibility conforms to the chapter. This includes the liquid argon and liquid helium and liquid nitrogen cryogenic systems. It also includes the high pressure air system, and the high pressure gas piping of the WAMUS and MDT gas systems. This is not an all inclusive compilation of test documentation. Some piping tests have their own engineering note. Other piping section test permits are included in separate safety review documents. So if it isn't here, that doesn't mean that it wasn't tested. D-Zero has a back up air supply system to add reliability to air compressor systems. The system includes high pressure piping which requires a review per FESHM 5031.1. The core system consists of a pressurized tube trailer, supply piping into the building and a pressure reducing regulator tied into the air compressor system discharge piping. Air flows from the trailer if the air compressor discharge pressure drops below the regulator setting. The tube trailer is periodically pumped back up to approximately 2000 psig. A high pressure compressor housed in one of the exterior buildings is used for that purpose. The system was previously documented, tested and reviewed for Run I, except for the recent addition of piping to and from the high pressure compressor. The following documents are provided for review of the system: (1) Instrument air flow schematic, drg. 3740.000-ME-273995 rev. H; (2) Component list for air system; (3) Pressure testing permit for high pressure piping; (4) Documentation from Run I contained in D-Zero Engineering note

Sweat, Michael J.

2013-01-01

During May through September 2012, the U.S. Geological Survey, in cooperation with the Bureau of Land Management, inventoried and assessed existing water wells in southwestern Wyoming for inclusion in a possible groundwater-monitor network. Records were located for 3,282 wells in the upper Green River Basin, which includes the U.S. Geological Survey study area and the proposed Normally Pressured Lance natural gas development project area. Records for 2,713 upper Green River Basin wells were determined to be unique (not duplicated) and to have a Wyoming State Engineers Office permit. Further, 376 of these wells were within the U.S. Geological Survey Normally Pressured Lance study area. Of the 376 wells in the U.S. Geological Survey Normally Pressured Lance study area, 141 well records had sufficient documentation, such as well depth, open interval, geologic log, and depth to water, to meet many, but not always all, established monitor well criteria. Efforts were made to locate each of the 141 wells and to document their current condition. Field crews were able to locate 121 of the wells, and the remaining 20 wells either were not located as described, or had been abandoned and the site reclaimed. Of the 121 wells located, 92 were found to meet established monitor well criteria. Results of the field efforts during May through September 2012, and specific physical characteristics of the 92 wells, are presented in this report.

Feasibility study is conducted for introduction of a top pressure recovery turbine (TRT) in China's Panzhihua Iron and Steel (Group) Company, Sichuan Province, for the potential project to simultaneously contribute to abatement of the greenhouse effect gases and to sustainable economic development of the counterpart country. This project considers to adopt the TRTs in 3 blast furnaces (No.1 to 3) of the 4 furnaces in service at the works, producing 2,500,000 t/y of crude steel, where the No.4 furnace is already provided with the model system and not considered in this project. According to the feasibility study results, the total fund required is 5.46 billion yen (Japan-made facilities: 4.172 billion yen, and China-made facilities: 1.288 billion yen), energy-saving effect is 36,467 t/y as crude, greenhouse effect gas emission abatement effect: 112,830 t/y as CO2, and pay-off period is 8.3 years. This plan considers to adopt almost the same facilities as those for the model project on a commercial basis. The taxes will be applied to the Japan-made facilities at a rate of 30% or more, although they were free for the model project, which should squeeze the investment effects. For the TRT project to be realized, low-interest fund is essential, and environmental yen loans will be necessary. (NEDO)

To evaluate the effectiveness of information and communication technologies in the undergraduate students' pressure ulcer training as a learning tool, compared with traditional teaching methods. Pressure ulcers constitute one of the great challenges faced by nursing professionals. Currently, pressure ulcer training is based on traditional on-campus teaching, involving lecture-style classes with frequent use of photographs of the wounds. This traditional training has some important weaknesses that can put the efficacy of the training at risk. A randomised controlled trial was developed including undergraduate nursing students. The intervention group used an adaptive self-learning e-learning tool developed by the research team (ePULab) for pressure ulcer assessment and treatment. The control group received a traditional on-campus class on the same topic. Pretest and post-test questionnaires were designed to assess the students' ability in pressure ulcer diagnosis and treatment. The educational intervention based on the use of the ePULab tool produced significantly better learning acquisition results than those obtained by traditional lecture-style classes: the total score improved in the control group from 8·23 (SD 1·23)-11·6 (SD 2·52) after the lecture, whereas in the intervention group, the knowledge score changed from 8·27 (SD 1·39)-15·83 (SD 2·52) (p = 0·01) with the use of ePULab. The results show a higher effectiveness of the devised e-learning approach for education on management of pressure ulcers. Our results reveal the suitability of the ePULab e-learning tool as an effective instrument for training on assessment of and treatment for pressure ulcers and its potential impact on clinical decision-making. © 2013 John Wiley & Sons Ltd.

The demand for refined petroleum products in Iran: Estimation and projection

1990-01-01

The estimation and projection of the demand for refined petroleum products of the OPEC states, are important for the world petroleum market from both the demand and supply sides. In this context, this study forms an econometric model to estimte the demand for the total and four major refined petroleum products (RPPs) in Iran and project their future trends into the year 2000. The fact that Iran has the largest domestic demand for RPPs among all the OPEC members has motivated some research primarily to study the structure of the demand for such products. None, however, has utilized econometric models to estimate or project the demand for RPPs. The first section of this study discusses the structure of the Iranian energy market. Next, the demand functions for gasoline, kerosine, gas oil, fuel oil, and the total RPPs in Iran are estimated. The third section puts together the demand functions to form a model used to project the demand for RPPs up to the year 2000 under an historical scenario. Finally, some condlusions are offered. 7 tabs

RegionsТ Competition for Investment Projects in Forest Development

Directory of Open Access Journals (Sweden)

Valentina Fedorovna Lapo

2014-06-01

Full Text Available The author considers the problem of competition between regions for investments. It is hypothesized that the presence of legislative stimulating benefits in a particular region, ceteris paribus, promotes investment flows in forest projects from other regions and is an instrumentl of inter-regional competition. To test the hypotheses the researcher uses a modified model with spatial weighted exogenous variables in order to assess the spatial effects. The obtained estimates indicate the presence of spatial effects, both negative (an inter-regional competition for investment and positive (agglomeration effects. The author argues that the process of inter-regional competition for investment in projects on forest development is caused by benefits under taxes and payments into the regional budget, regulation of pricing (including actions by natural and local monopolies and depreciation policy and solutions to put some forest projects in the list of priority ones. Along with this, the paper identifies agglomeration effects induced by a number of benefits: direct dealings in investment by financing or property contribution, subsidies, state guarantees, credit security and partial payment of interest

To comprehensively assess condom use errors and problems reported by women who apply condoms, given the lack of data on this aspect of condom use. Data from a questionnaire survey, using a 3-month recall period, was analyzed for a convenience sample of 102 college women who put condoms on their male partner(s) for sex (vaginal, anal, or oral). The percentage of the sample reporting that an error or problem occurred at least once is presented. Fifty-one percent put the condom on after starting sex, and 15% took the condom off before ending sex. Forty-eight percent wanted a condom but didn't have one, 46% did not leave space at the tip, 30% put the condom on wrong side up and had to flip the condom over, 26% did not use a lubricant, and 15% wanted a water-based lubricant and did not have any available. Twenty-five percent reported that their partners lost erections in association with condom use. Twenty-eight percent reported breakage, slippage, or both. Higher error scores were found for those who reported: 1) breakage or slippage, 2) partner erection problems, 3) use of another form of contraception, and 4) not having received instruction in correct condom use. Educating women as well as men about correct condom use, in addition to promoting consistent condom use, may be an important public health strategy.

Next Generation Life Support (NGLS) is one of several technology development projects sponsored by NASA s Game Changing Development Program. The NGLS Project is developing life support technologies (including water recovery and space suit life support technologies) needed for humans to live and work productively in space. NGLS has three project tasks: Variable Oxygen Regulator (VOR), Rapid Cycle Amine (RCA) swing bed, and Alternative Water Processor (AWP). The RCA swing bed and VOR tasks are directed at key technology needs for the Portable Life Support System (PLSS) for an Advanced Extravehicular Mobility Unit, with focus on test article development and integrated testing in an Advanced PLSS in cooperation with the Advanced Extra Vehicular Activity (EVA) Project. An RCA swing-bed provides integrated carbon dioxide removal and humidity control that can be regenerated in real time during an EVA. The VOR technology will significantly increase the number of pressure settings available to the space suit. Current space suit pressure regulators are limited to only two settings whereas the adjustability of the advanced regulator will be nearly continuous. The AWP effort, based on natural biological processes and membrane-based secondary treatment, will result in the development of a system capable of recycling wastewater from sources expected in future exploration missions, including hygiene and laundry water. This paper will provide a status of technology development activities and future plans.

This document summarizes the work that was ongoing when Project W-340 was put on hold. Project W-340: Tank 241-C-106 Manipulator Retrieval System, was a candidate FY98 Major System Acquisition. The project was to develop, procure and deploy a Long Reach Manipulator (LRM) waste retrieval system to provide an alternate method to completing the in-tank demonstration of Single Shell Tank waste retrieval technology. The need for enhanced capabilities derives from (1) the inability of the baseline technology to retrieve certain hard waste forms; (2) uncertainty in the quantity of leakage which will be allowed. Numerous studies over the years have identified an arm architecture as a promising retrieval technology to overcome these concerns. The W340 project was intended to further develop and demonstrate this alternative, as part of selecting the best approach for all tanks. Prior to completing the effort, it was determined that an LRM system was too architecture specific and was envisioned to be too expensive for a one time demonstration of retrieval technology. At the time the work was stopped, an effort was underway to broaden the project scope to allow alternatives to an arm-based system

A common plantar pressure analysis technique requires dividing the pressure distribution into regions based on key landmarks of the foot. Typically, this is done using visual inspection of the footprint and is subject to error when there is abnormal foot contact. A novel, robust method of synchronizing motion capture and plantar pressure data was created that allows for motion capture markers to be projected onto the plantar pressure mat for accurate subdivision of the foot. Validation studies showed that spatial synchronization of the plantar pressure and motion capture systems was determined to be accurate within 1 sensel. Copyright 2010 Elsevier B.V.

Because medical students have many different learning styles, the authors, medical students at Mayo Clinic, College of Medicine researched the history of anatomical specimen procurement, reviewing topic-related film, academic literature, and novels, to write, direct, and perform a dramatization based on Robert Louis Stevenson's The Body-Snatcher. Into this performance, they incorporated dance, painting, instrumental and vocal performance, and creative writing. In preparation for the performance, each actor researched an aspect of the history of anatomy. These micro-research projects were presented in a lecture before the play. Not intended to be a research study, this descriptive article discusses how student research and ethics discussions became a theatrical production. This addition to classroom and laboratory learning addresses the deep emotional response experienced by some students and provides an avenue to understand and express these feelings. This enhanced multimodal approach to"holistic learning" could be applied to any topic in the medical school curriculum, thoroughly adding to the didactics with history, humanities, and team dynamics.

Searching for the neutrinoless double beta decay (NLDBD) is now regarded as the topmost promising technique to explore the nature of neutrinos after the discovery of neutrino masses in oscillation experiments. PandaX-III (particle and astrophysical xenon experiment III) will search for the NLDBD of 136Xe at the China Jin Ping Underground Laboratory (CJPL). In the first phase of the experiment, a high pressure gas Time Projection Chamber (TPC) will contain 200 kg, 90% 136Xe enriched gas operated at 10 bar. Fine pitch micro-pattern gas detector (Microbulk Micromegas) will be used at both ends of the TPC for the charge readout with a cathode in the middle. Charge signals can be used to reconstruct the electron tracks of the NLDBD events and provide good energy and spatial resolution. The detector will be immersed in a large water tank to ensure 5 m of water shielding in all directions. The second phase, a ton-scale experiment, will consist of five TPCs in the same water tank, with improved energy resolution and better control over backgrounds.

RF BREAKDOWN STUDIES USING PRESSURIZED CAVITIES

Energy Technology Data Exchange (ETDEWEB)

Johnson, Rolland

2014-09-21

Many present and future particle accelerators are limited by the maximum electric gradient and peak surface fields that can be realized in RF cavities. Despite considerable effort, a comprehensive theory of RF breakdown has not been achieved and mitigation techniques to improve practical maximum accelerating gradients have had only limited success. Part of the problem is that RF breakdown in an evacuated cavity involves a complex mixture of effects, which include the geometry, metallurgy, and surface preparation of the accelerating structures and the make-up and pressure of the residual gas in which plasmas form. Studies showed that high gradients can be achieved quickly in 805 MHz RF cavities pressurized with dense hydrogen gas, as needed for muon cooling channels, without the need for long conditioning times, even in the presence of strong external magnetic fields. This positive result was expected because the dense gas can practically eliminate dark currents and multipacting. In this project we used this high pressure technique to suppress effects of residual vacuum and geometry that are found in evacuated cavities in order to isolate and study the role of the metallic surfaces in RF cavity breakdown as a function of magnetic field, frequency, and surface preparation. One of the interesting and useful outcomes of this project was the unanticipated collaborations with LANL and Fermilab that led to new insights as to the operation of evacuated normal-conducting RF cavities in high external magnetic fields. Other accomplishments included: (1) RF breakdown experiments to test the effects of SF6 dopant in H2 and He gases with Sn, Al, and Cu electrodes were carried out in an 805 MHz cavity and compared to calculations and computer simulations. The heavy corrosion caused by the SF6 components led to the suggestion that a small admixture of oxygen, instead of SF6, to the hydrogen would allow the same advantages without the corrosion in a practical muon beam line.

Harsh, Kevin

2014-01-01

Robust, miniaturized sensing systems are needed to improve performance, increase efficiency, and track system health status and failure modes of advanced propulsion systems. Because microsensors must operate in extremely harsh environments, there are many technical challenges involved in developing reliable systems. In addition to high temperatures and pressures, sensing systems are exposed to oxidation, corrosion, thermal shock, fatigue, fouling, and abrasive wear. In these harsh conditions, sensors must be able to withstand high flow rates, vibration, jet fuel, and exhaust. In order for existing and future aeropropulsion turbine engines to improve safety and reduce cost and emissions while controlling engine instabilities, more accurate and complete sensor information is necessary. High-temperature (300 to 1,350 C) capacitive pressure sensors are of particular interest due to their high measurement bandwidth and inherent suitability for wireless readout schemes. The objective of this project is to develop a capacitive pressure sensor based on silicon carbon nitride (SiCN), a new class of high-temperature ceramic materials, which possesses excellent mechanical and electric properties at temperatures up to 1,600 C.

Structural analysis and evaluation for the design of pressure vessel

International Nuclear Information System (INIS)

Arai, K.; Uragami, K.; Funada, T.; Baba, K.; Kira, T.

1977-01-01

For the design of pressure vessel, the detailed structural analysis such as the fatigue analysis under operating conditions is required by ASME Code or Japanese regulation. Accordingly, it should be verified by the analysis that the design of the pressure vessel is in compliance with the stress limitation defined in the Code or the regulation. However, it was apparent that the analysis is very complicated and takes a lot of time to evaluate in accordance with the Code requirements. Thereupon we developed the computer program by which we can perform the stress analysis with correctness and comparatively in a short period of design work reflecting the calculation results on detailed drawings to be used for fabrication. The computer program is controlled in combination with the system of the design work and out put list of the program can be directly used for the stress analysis report which is issued to customers. In addition to the above computer program, we developed the specific three dimensional finite element computer program to make sure of the structural integrity of the vessel head and flanges which are most complex for the analysis compared with the stress distribution measured by strain gauges on the vessel head and flange. Besides the structural analysis, the fracture mechanics analysis for the purpose of preventing the pressure vessel from the brittle fracture during heat-up and cool-down operation is also important and thereby we showed herein that the pressure vessel is in safety against the brittle fracture for the specified operating conditions. As a result of the above-mentioned analysis, the pressure vessel is designed with safety from the stand-points of the structural intensity and the fracture mechanics. (auth.)

Theory of affine projection algorithms for adaptive filtering

CERN Document Server

Ozeki, Kazuhiko

2016-01-01

This book focuses on theoretical aspects of the affine projection algorithm (APA) for adaptive filtering. The APA is a natural generalization of the classical, normalized least-mean-squares (NLMS) algorithm. The book first explains how the APA evolved from the NLMS algorithm, where an affine projection view is emphasized. By looking at those adaptation algorithms from such a geometrical point of view, we can find many of the important properties of the APA, e.g., the improvement of the convergence rate over the NLMS algorithm especially for correlated input signals. After the birth of the APA in the mid-1980s, similar algorithms were put forward by other researchers independently from different perspectives. This book shows that they are variants of the APA, forming a family of APAs. Then it surveys research on the convergence behavior of the APA, where statistical analyses play important roles. It also reviews developments of techniques to reduce the computational complexity of the APA, which are important f...

An environmental pressure index proposal for urban development planning based on the analytic network process

International Nuclear Information System (INIS)

Gomez-Navarro, Tomas; Garcia-Melon, Monica; Acuna-Dutra, Silvia; Diaz-Martin, Diego

2009-01-01

This paper introduces a new approach to prioritize urban planning projects according to their environmental pressure in an efficient and reliable way. It is based on the combination of three procedures: (i) the use of environmental pressure indicators, (ii) the aggregation of the indicators in an Environmental Pressure Index by means of the Analytic Network Process method (ANP) and (iii) the interpretation of the information obtained from the experts during the decision-making process. The method has been applied to a proposal for urban development of La Carlota airport in Caracas (Venezuela). There are three options which are currently under evaluation. They include a Health Club, a Residential Area and a Theme Park. After a selection process the experts chose the following environmental pressure indicators as ANP criteria for the project life cycle: used land area, population density, energy consumption, water consumption and waste generation. By using goal-oriented questionnaires designed by the authors, the experts determined the importance of the criteria, the relationships among criteria, and the relationships between the criteria and the urban development alternatives. The resulting data showed that water consumption is the most important environmental pressure factor, and the Theme Park project is by far the urban development alternative which exerts the least environmental pressure on the area. The participating experts coincided in appreciating the technique proposed in this paper is useful and, for ranking ordering these alternatives, an improvement from traditional techniques such as environmental impact studies, life-cycle analysis, etc.

European financial support and succesful road PPP Projects

2016-07-01

The EU has been promoting the use of PPPs in order to accelerate the development of the Trans-European Transport Network (TEN-T) for ensuring economic, social and territorial cohesion and increasing accessibility throughout the Union. To encourage the use of PPPs, the European Commission has put several financing mechanisms at the disposal of the Member States, including a series of innovative financial instruments developed along with the European Investment Bank. The Bank has in turn played a major role in the promotion and financing of PPPs across the EU. The paper undertakes a review of the main financial instruments developed by the EU that are available to PPPs so as to determinate to what extent the European financial support has been channelled to road projects under that scheme in Spain. On the basis of the results obtained, a multiple regression model has been developed to analyse whether the PPP projects which enjoyed the financial support of the European Union tend to be significantly more successful from an economic point of view. The paper concludes that there is a positive correlation between receiving European financial support and the success of the PPP road projects. (Author)

Ultra-high pressure water jet: Baseline report

International Nuclear Information System (INIS)

1997-01-01

The ultra-high pressure waterjet technology was being evaluated at Florida International University (FIU) as a baseline technology. In conjunction with FIU's evaluation of efficiency and cost, this report covers the evaluation conducted for safety and health issues. It is a commercially available technology and has been used for various projects at locations throughout the country. The ultra-high pressure waterjet technology acts as a cutting tool for the removal of surface substrates. The Husky trademark pump feeds water to a lance that directs the high pressure water at the surface to be removed. The safety and health evaluation during the testing demonstration focused on two main areas of exposure. These were dust and noise. The dust exposure was found to be minimal, which would be expected due to the wet environment inherent in the technology, but noise exposure was at a significant level. Further testing for noise is recommended because of the outdoor environment where the testing demonstration took place. In addition, other areas of concern found were arm-hand vibration, ergonomics, heat stress, tripping hazards, electrical hazards, lockout/tagout, fall hazards, slipping hazards, hazards associated with the high pressure water, and hazards associated with air pressure systems

Pressure ulcer prevention in patients with advanced illness.

Science.gov (United States)

White-Chu, E Foy; Reddy, Madhuri

2013-03-01

Pressure ulcers can be challenging to prevent, particularly in patients with advanced illnesses. This review summarizes the relevant literature since 2011. Through a MEDLINE and CINAHL database search from January 1, 2011 to June 1, 2012, a total of 14 abstracts were found addressing the prevention of pressure ulcers in persons with advanced illness. Search terms included pressure ulcer, prevention, and control. Advanced illness was defined as patients transitioning from curative to supportive and palliative care. Ten original studies and four review articles specifically addressed pressure ulcer prevention. There were four articles that specifically addressed patients with advanced illness. The studies varied in quality. One systematic review, one randomized controlled trial, three prospective trials, two retrospective trials, one cost-effectiveness analysis, one quality improvement project, one comparative descriptive design, and four review articles were found. The interventions for pressure ulcer prevention were risk assessment, repositioning, surface selection, nutritional support and maintenance of skin integrity with or without incontinence. The quality of pressure ulcer prevention studies in persons with advanced illness is poor. Increased number and higher quality studies are needed to further investigate this important topic for these fragile patients.

In order to fulfill future emissions and OBD regulations, whilst meeting increasing demands for driveability and refinement, new technologies for SI engines have to be found in terms of sensors and algorithms for engine control units. One promising way, explored in the AENEAS collaborative project between DaimlerChrysler, Kistler, Ricardo and the European Commission, is to optimize the behavior of the system by using in-cylinder measurements and analysing them with modern control algorithms. In this paper a new engine management system based on combustion pressure sensing is presented. The pressure sensor is designed to give a reliable and accurate signal of the full pressure trace during a working cycle. With the application of new technologies low cost manufacturing appears to be achievable, so that an application in mass production can be considered. Furthermore, model-based algorithms were developed to allow optimal control of the engine based on the in-cylinder measurements. The algorithms incorporate physical principles to improve efficiency, emissions and to reduce the parameterisation effort. In the paper, applications of the combustion pressure signal for air mass estimation, knock detection, ignition control cam phase detection and diagnosis are discussed. (author)

Auction Mechanism of Micro-Grid Project Transfer

Directory of Open Access Journals (Sweden)

Yong Long

2017-10-01

Full Text Available Micro-grid project transfer is the primary issue of micro-grid development. The efficiency and quality of the micro-grid project transfer directly affect the quality of micro-grid project construction and development, which is very important for the sustainable development of micro-grid. This paper constructs a multi-attribute auction model of micro-grid project transfer, which reflects the characteristics of micro-grid system and the interests of stakeholders, calculates the optimal bidding strategy and analyzes the influence of relevant factors on auction equilibrium by multi-stage dynamic game with complete information, and makes a numerical simulation analysis. Results indicate that the optimal strategy of auction mechanism is positively related to power quality, energy storage quality, and carbon emissions. Different from the previous lowest price winning mechanism, the auction mechanism formed in this paper emphasizes that the energy suppliers which provide the comprehensive optimization of power quality, energy storage quality, carbon emissions, and price will win the auction, when both the project owners and energy suppliers maximize their benefits under this auction mechanism. The auction mechanism is effective because it is in line with the principle of individual rationality and incentive compatibility. In addition, the number of energy suppliers participating in the auction and the cost of the previous auction are positively related to the auction equilibrium, both of which are adjusting the equilibrium results of the auction. At the same time, the utilization rate of renewable energy and the comprehensive utilization of energy also have a positive impact on the auction equilibrium. In the end, this paper puts forward a series of policy suggestions about micro-grid project auction. The research in this paper is of great significance to improve the auction quality of micro-grid projects and promote the sustainable development of micro-grid.

Full Text Available One of the major challenges facing society today is increasing proportion of its elderly population. Nowadays, elderliness along with its all psychological, socio-cultural, ideological and economic aspects have become a serious and challenging issue affecting families in developing and developed countries. Thus, the current study aimed to examine families’ experiences of putting their elders in nursing homes. A phenomenological research method was employed to pursue this qualitative study. The samples of the study were selected through purposive sampling method; and data collection proceeded until it reached to the data saturation within 10 participants. The instruments adopted by the researcher include note-taking and in-depth and unstructured interviews with the families of the elderly who put their elders in nursing homes. The obtained data were analyzed using Colaizzi’s seven-step process of analysis. The four general themes derived include isolation, peace, abusiveness, children’s inability to look after their elders and guilty conscience; each of which contained some sub-themes. According to the results, it is essential to take the social, economic and health support of the elderly into consideration and to provide the necessary context for improving the life quality of the elderly residing in nursing homes through formulating, planning and making appropriate policies.

Wave Shape and Impact Pressure Measurements at a Rock Coast Cliff

Science.gov (United States)

Varley, S. J.; Rosser, N. J.; Brain, M.; Vann Jones, E. C.

2016-02-01

Rock coast research focuses largely on wave behaviour across beaches and shore platforms but rarely considers direct wave interaction with cliffs. Hydraulic action is one of the most important drivers of erosion along rock coasts. The magnitude of wave impact pressure has been shown by numerical and laboratory studies to be related to the wave shape. In deep water, a structure is only subjected to the hydrostatic pressure due to the oscillating clapotis. Dynamic pressures, related to the wave celerity, are exerted in shallower water when the wave is breaking at the point of impact; very high magnitude, short duration shock pressures are theorised to occur when the approaching wavefront is vertical. As such, wave shape may directly influence the potential of the impact to weaken rock and cause erosion. Measurements of impact pressure at coastal cliffs are limited, and the occurrence and influence of this phenomenon is currently poorly constrained. To address this, we have undertaken a field monitoring study on the magnitude and vertical distribution of wave impact pressures at the rocky, macro-tidal coastline of Staithes, North Yorkshire, UK. A series of piezo-resistive pressure transducers and a camera were installed at the base of the cliff during low tide. Transducers were deployed vertically up the cliff face and aligned shore-normal to capture the variation in static and dynamic pressure with height during a full spring tidal cycle. Five minute bursts of 5 kHz pressure readings and 4 Hz wave imaging were sampled every 30 minutes for six hours during high tide. Pressure measurements were then compensated for temperature and combined with wave imaging to produce a pressure time series and qualitative wave shape category for each wave impact. Results indicate the presence of a non-linear relationship between pressure impact magnitude, the occurrence of shock pressures, wave shape and tidal stage, and suggest that breaker type on impact (and controls thereof) may

An analysis of project selection and assignment criteria of Danish tenders in Europe

Jasper Kranker Larsen

2013-12-01

Full Text Available Public construction agencies are one of the largest developers within the Danish construction industry, where such agencies own and develop new public construction projects. Most of these projects are put out in European tender. This study analyses the selection and assignment criteria employed by these agencies in different types of public sector projects. Some of the objectives pursued by the study include the determination of 1/ the selection and assignment criteria mostly used in Danish public tenders 2/ how different types of projects use selection and assignment criteria in the bidding process, and 3/ any significant difference between the use of selection and assignment criteria in Danish public construction projects. The study uses a quantitative research approach where 157 Danish public tender cases were selected from the European Tenders Electronic Daily database between the period: January 2010 to March 2013. Fisher's Exact Test was conducted to determine if there was any significant use of some selection and assignment criteria. The findings of the study showed that invited tenders with pre-qualification and lowest price in 69.8% of the tenders are the most used selection and assignment criteria, with little regard to project type.

Change management in information systems projects for public organizations

Directory of Open Access Journals (Sweden)

Ewa Ziemba

2015-08-01

Full Text Available It can be argued that public organizations, in order to provide the public with sufficient services in the current, highly competitive and continuously evolving environment, require changes. The changes that become necessary are often related to the implementation of information systems (IS. Moreover, when organizations are faced with changes, a change management (CM process needs to be put in place. CM theories that are currently available to practitioners and academics are often contradictory; they mostly lack empirical evidence and are supported by unchallenged hypotheses concerning the nature of the contemporary CM. The aim of this paper is, therefore, to identify critical success factors (CFSs for CM in IS projects. In order to reach this aim an explanation of changes in public organizations and the nature of CM are presented. Following this, a framework of CFSs for CM in IS projects are identified based on the literature review. The paper also examines two IS projects and uses them to demonstrate CFSs influencing CM in IS projects in Polish pubic organizations. A discussion of the research findings is provided and the paper concludes with a presentation of the study’s contributions and limitations as well as the stream of future work.

Stahl, Bernd Carsten; Rainey, Stephen; Harris, Emma; Fothergill, B Tyr

2018-05-14

We describe current practices of ethics-related data governance in large neuro-ICT projects, identify gaps in current practice, and put forward recommendations on how to collaborate ethically in complex regulatory and normative contexts. We undertake a survey of published principles of data governance of large neuro-ICT projects. This grounds an approach to a normative analysis of current data governance approaches. Several ethical issues are well covered in the data governance policies of neuro-ICT projects, notably data protection and attribution of work. Projects use a set of similar policies to ensure users behave appropriately. However, many ethical issues are not covered at all. Implementation and enforcement of policies remain vague. The data governance policies we investigated indicate that the neuro-ICT research community is currently close-knit and that shared assumptions are reflected in infrastructural aspects. This explains why many ethical issues are not explicitly included in data governance policies at present. With neuro-ICT research growing in scale, scope, and international involvement, these shared assumptions should be made explicit and reflected in data governance.

THE CONVERSION OF LATE-TYPE INTO EARLY-TYPE DWARF GALAXIES BY RAM-PRESSURE STRIPPING IN THE FORNAX CLUSTER

International Nuclear Information System (INIS)

De Rijcke, S.; Van Hese, E.; Buyle, P.

2010-01-01

We put to the test the hypothesis that the Fornax cluster dwarf galaxies are mostly a relatively recently acquired population, of which the star-forming, late-type members are converted into quiescent, early-type ones by ram-pressure stripping while being on orbits that plunge inside the inner few hundred kiloparsecs of the cluster. We construct dynamical models with different anisotropy profiles for the dwarf galaxy population and show that only extremely radially anisotropic orbital distributions are in agreement with the available morphological, positional, and kinematical data, especially with the radially increasing late-to-early-type ratio. This corroborates the idea that the Fornax cluster dwarfs are an infall population and that environmental factors, in this case ram-pressure stripping, play a prominent role in converting late-type dwarfs into early-type ones.

1988-01-01

The OECD Halden Reactor project is an agreement between OECD member countries. It was first signed in 1958 and since then regularly renewed every third year. The activities at the Project is centred around the Halden heavy water rector, the HBWR. The reseach programme comprizes studies of fuel performance under various operating conditions, and the application of computers for process control. The HBWR is equipped for exposing fuel rods to temperatures and pressures, and at heat ratings met in modern BWR's and PWR's. A range of in-core instruments are available, permitting detailed measurements of the reactions of the fuel, including mechanical deformations, thermal behaviour, fission gas release, and corrosion. In the area of computer application, the studies of the communication between operator and process, and the surveillance and control of the reactor core, are of particular interst for reactor operation. 1988 represents the 30th year since the Project was started, and this publication is produced to mark this event. It gives and account of the activities and achievements of the Project through the years 1958-1988

Artur Biskupek

2016-12-01

Full Text Available Purpose of the article: The article show summarized information about stakeholders and their role in project implementation based on literature review. The second part of the article is dedicated for the research about stakeholder influence on project implementation. The only condition to participate in the survey was managing projects. Although the respondents are employed in the area of south Poland, they implement projects all over Poland. The research tool was a questionnaire which was sent by e-mail to the respondents. 90 project managers from the area of south Poland were invited to join the project, and 62 people sent back a completed questionnaire. Methodology/methods: The research was done by a questionnaire with twenty two question, which was divided into three parts. The first part was the imprint, which consisted of three questions. The second part consisted of two questions, which concerned the way of defining the word “stakeholder”. The third part concerned the topic of the research and consisted of seventeen questions. Scientific aim: The aim of the article is presenting the results of the research which was done, to show the research results of project stakeholder influence on the project implementation. Findings: The results received from the survey in the process of analysis and interpretation allow to put forward a thesis that stakeholders as a whole group are significant for the implementation of the whole project. Their impact is so important that it is possible to tell that they decide also about the project success or failure. Conclusions: The respondents show that stakeholders affect every area in large extent or very big extent. The fact has been proved in table 1 which shows the most frequently chosen answers by responders. However, by conducted analysis by the standard deviation it is possible to see a large dispersion of the results.

Putting people into the picture.

Rowley, J

1989-01-01

In an interview with the newly appointed head of the Population, Women, and Natural Resources Program of the International Union for the Conservation of Nature (IUCN), Dr. Pietronella van den Oever reflects on the concern about natural resources and working with women, rural development, and agricultural extension projects. She considers her job to have three main objectives: 1) to try to increase the in-house knowledge among the staff about population matters and also in the country where they work; 2) to conceptualize the linkages between the sustainable use of natural resources and demographic variables because of the struggle to integrate population concerns into programs (the example of Zaire is given, which had the same level of fertility and maternal mortality as Mali with very few resources; this shows the lack of knowledge and the effect of resources on population); 3) to test the practical application of joint policies, strategies, and projects relating to conservation of natural resources and population. This can be done if population and natural resources projects are integrated. As a start a population reference library will be set up and a population data tape will be produced for staff who travel to various countries. Other initiatives will be the formation of a committee on population/resources links, and the field testing of the unit's Population, Resources, and Development Guidebook, particularly in relation to Pakistan's national conservation strategy. Eventually a work book is hoped to be developed from this for those wanting to plan their natural resources. In addition, the program is helping to plan the Africa Women's Assembly in Harare, Zimbabwe, to be held in February 1990. The objective is to involve local people in conserving nature. Since women are heavily involved in agriculture, they should be educated to use resources in a sustainable way.

Nuclear reactor pressure vessel surveillance capsule examinations. Application of American Society for Testing and Materials Standards

International Nuclear Information System (INIS)

Perrin, J.S.

1978-01-01

A series of pressure vessel surveillance capsules is installed in each commercial nuclear power plant in the United States. A capsule typically contains neutron dose meters, thermal monitors, tensile specimens, and Charpy V-notch impact specimens. In order to determine property changes of the pressure vessel resulting from irradiation, surveillance capsules are periodically removed during the life of a reactor and examined. There are numerous standards, regulations, and codes governing US pressure vessel surveillance capsule programmes. These are put out by the US Nuclear Regulatory Commission, the Boiler and Pressure Vessel Committee of the American Society of Mechanical Engineers, and the American Society for Testing and Materials (ASTM). A majority of the pertinent ASTM standards are under the jurisdiction of ASTM Committee E-10 on Nuclear Applications and Measurements of Radiation Effects. The standards, regulations, and codes pertaining to pressure vessel surveillance play an important role in ensuring reliability of the nuclear pressure vessels. ASTM E 185-73 is the Standard Recommended Practice for Surveillance Tests for Nuclear Reactors. This standard recommends procedures for both the irradiation and subsequent testing of surveillance capsules. ASTM E 185-73 references many additional specialized ASTM standards to be followed in specific areas of a surveillance capsule examination. A key element of surveillance capsule programmes is the Charpy V-notch impact test, used to define curves of fracture behaviour over a range of temperatures. The data from these tests are used to define the adjusted reference temperature used in determining pressure-temperature operating curves for a nuclear power plant. (author)

Lincoln Composites operates a facility for designing, testing, and manufacturing composite pressure vessels. Lincoln Composites also has a U.S. Department of Energy (DOE)-funded project to develop composite tanks for high-pressure hydrogen storage. The initial stage of this project involves testing the permeation of high-pressure hydrogen through polymer liners. The company recently moved and is constructing a dedicated research/testing laboratory at their new location. In the meantime, permeation tests are being performed in a corner of a large manufacturing facility. The safety review team visited the Lincoln Composites site on May 25, 2010. The project team presented an overview of the company and project and took the safety review team on a tour of the facility. The safety review team saw the entire process of winding a carbon fiber/resin tank on a liner, installing the boss and valves, and curing and painting the tank. The review team also saw the new laboratory that is being built for the DOE project and the temporary arrangement for the hydrogen permeation tests.

Putting science at the heart of European policy

CERN Multimedia

2015-01-01

One year ago, the incoming European Commission President Jean-Claude Juncker shocked the scientific world by scrapping the post of Chief Scientific Advisor. This week, the Commission made amends by launching a well-considered Scientific Advisory Mechanism (SAM) that not only puts science back at the heart of policy, but does so in a much more structured and robust way than conferring such responsibility on a single individual.     The SAM has two independent strands: an advisory group of seven scientists, and funding through the Horizon 2020 programme for national academies and learned societies to network and collaborate on policy issues. Both are backed up by a secretariat at Commission headquarters in Brussels. When Mr Juncker scrapped the role of Chief Scientific Advisor, it was against a backdrop of sometimes vitriolic attacks on the incumbent, Anne Glover, due to her outspoken views on GMOs. Mr Juncker’s move was seen by some as simply giving in to a powerful lob...

Case studies in control putting theory to work

CERN Document Server

Juričić, Đani

2013-01-01

Case Studies in Control presents a framework to facilitate the use of advanced control concepts in real systems based on two decades of research and over 150 successful applications for industrial end-users from various backgrounds. In successive parts the text approaches the problem of putting the theory to work from both ends, theoretical and practical. The first part begins with a stress on solid control theory and the shaping of that theory to solve particular instances of practical problems. It emphasizes the need to establish by experiment whether a model-derived solution will perform properly in reality. The second part focuses on real industrial applications based on the needs and requirements of end-users. Here, the engineering approach is dominant but with theoretical input of varying degree depending on the particular process involved. Following the illustrations of the progress that can be made from either extreme of the well-known theory–practice divide, the text proceeds to a third part relate...

Waste-isolation projects, FY 1978

International Nuclear Information System (INIS)

Ramspott, L.D.

1979-01-01

This report describes Lawrence Livermore Laboratory (LLL) activities during FY 1978 in support of the National Waste Terminal Storage Program. Current projects at LLL fall into three categories: (1) field testing, (2) laboratory rock mechanics measurements, and (3) laboratory studies of sorption and leaching. Field test activities conducted in the Climax granite at the Nevada Test Site included electrical heater tests, preparation for a spent-fuel-storage test, and planning for a series of rock mechanics tests. The heater tests determined the in situ thermal properties of Climax granite and its in situ permeability as a function of rock temperature. The two main laboratory rock mechanics projects involved (1) measurement of the permeability, electrical conductivity, and acoustic velocity of 15-cm-diam cores of granitic rocks over a range of confining pressure, pore (water) pressure, and deviatoric stress, and (2) measurement of rock thermal properties as a function of temperature and confining pressure in the presence of pore fluids to 770 0 K and 200 Mpa. The leaching studies made use of an LLL-designed, single-pass leaching apparatus with three solutions, two leach temperatures, and three flow rates. The material evaluated was Np--Pu-doped simulated waste glass from Battelle Pacific Northwest Laboratories. The sorption studies involved standard static measurements of the equilibrium distribution coefficient (K/sub d/) for various radionuclides on a variety of rocks, and flow-through-core studies of dynamic sorption

methodology, offer results, very similar to the obtained ones that are validated against experiences of experimental facilities such like the experimental facility UPTF (Upper Plenum Test Facility). An important observation arises from the analysis of the behavior of the temperature in the fluid contained in the RPV downcomer, below the cold leg level, versus the water injected temperature (T HPI ) by the CAN-I low pressure emergency system (T j system). It is possible to be noticing that when the temperature T HPI increases, the possibility that the conditions occur so that a phenomenon of PTS happens is decreasing. The temperature that is reached in the fuel elements, that is to say, that does not put in risk the structural integrity of the cladding of the fuel element, will fix the maximum limit for the temperature T HPI . We insist on the solution of engineering that would allow modifying the Emergency Core Cooler System (ECCS) behavior, extending the safety margin, what it means, the distance between the K lc of the material and the K l of the process. It is emphasized the excessive conservative hypotheses that have been used in all the previous studies and the necessity to replace them with other more realists that would allow to extend the safety margin. At the moment this safety margin based in these coefficients is about 22 C degrees. (author) [es
