2014-01-01

In this paper, DC-link voltage control in DC microgrids with photovoltaic (PV) generation and battery, is addressed based on an intelligent approach. The proposed strategy is based on the modeling of the power interface, i.e. power electronic converter, located between the PV array, battery and DC bus, by use of measurement data. For this purpose, a local model network (LMN) is developed to model the converter and then a local linear control (LLC) strategy is designed based on the LMN. Simula...

We previously reported in atrial myocytes that inhibition of cAMP-dependent protein kinase (PKA) by laminin (LMN)-integrin signaling activates β2-adrenergic receptor (β2-AR) stimulation of cytosolic phospholipase A2 (cPLA2). The present study sought to determine the signaling mechanisms by which inhibition of PKA activates β2-AR stimulation of cPLA2. We therefore determined the effects of zinterol (0.1 μM; zint-β2-AR) to stimulate ICa,L in atrial myocytes in the absence (+PKA) and presence (-PKA) of the PKA inhibitor (1 μM) KT5720 and compared these results with atrial myocytes attached to laminin (+LMN). Inhibition of Raf-1 (10 μM GW5074), phospholipase C (PLC; 0.5 μM edelfosine), PKC (4 μM chelerythrine) or IP3 receptor (IP3R) signaling (2 μM 2-APB) significantly inhibited zint-β2-AR stimulation of ICa,L in-PKA but not +PKA myocytes. Western blots showed that zint-β2-AR stimulation increased ERK1/2 phosphorylation in-PKA compared to +PKA myocytes. Adenoviral (Adv) expression of dominant negative (dn) -PKCα, dn-Raf-1 or an IP3 affinity trap, each inhibited zint-β2-AR stimulation of ICa,L in + LMN myocytes compared to control +LMN myocytes infected with Adv-βgal. In +LMN myocytes, zint-β2-AR stimulation of ICa,L was enhanced by adenoviral overexpression of wild-type cPLA2 and inhibited by double dn-cPLA2S505A/S515A mutant compared to control +LMN myocytes infected with Adv-βgal. In-PKA myocytes depletion of intracellular Ca2+ stores by 5 μM thapsigargin failed to inhibit zint-β2-AR stimulation of ICa,L via cPLA2. However, disruption of caveolae formation by 10 mM methyl-β-cyclodextrin inhibited zint-β2-AR stimulation of ICa,L in-PKA myocytes significantly more than in +PKA myocytes. We conclude that inhibition of PKA removes inhibition of Raf-1 and thereby allows β2-AR stimulation to act via PKCα/Raf-1/MEK/ERK1/2 and IP3-mediated Ca2+ signaling to stimulate cPLA2 signaling within caveolae. These findings may be relevant to the remodeling of �

EC-Marie Curie Initial Training Networks (ITN) projects aim to improve the career perspectives of young generations of researchers. Institutions from both academic and industry sectors form a collaborative network to recruit research fellows and provide them with opportunities to undertake research in the context of a joint research training program. In this frame, TOPOMOD - one of the training activities of EPOS, the new-born European Research Infrastructure for Geosciences - is a funded ITN project designed to investigate and model how surface processes interact with crustal tectonics and mantle convection to originate and develop topography of the continents over a wide range of spatial and temporal scales. The multi-disciplinary approach combines geophysics, geochemistry, tectonics and structural geology with advanced geodynamic numerical/analog modelling. TOPOMOD involves 8 European research teams internationally recognized for their excellence in complementary fields of Earth Sciences (Roma TRE, Utrecht, GFZ, ETH, Cambridge, Durham, Rennes, Barcelona), to which are associated 5 research institutions (CNR-Italy, Univ. Parma, Univ. Lausanne, Univ. Montpellier, Univ. Mainz) , 3 high-technology enterprises (Malvern Instruments, TNO, G.O. Logical Consulting) and 1 large multinational oil and gas company (ENI). This unique network places emphasis in experience-based training increasing the impact and international visibility of European research in modeling. Long-term collaboration and synergy are established among the overmentioned research teams through 15 cross-disciplinary research projects that combine case studies in well-chosen target areas from the Mediterranean, the Middle and Far East, west Africa, and South America, with new developments in structural geology, geomorphology, seismology, geochemistry, InSAR, laboratory and numerical modelling of geological processes from the deep mantle to the surface. These multidisciplinary projects altogether aim to

Theses Originality: An Initial Effort to Examine Students’ Final Projects

Full Text Available Thesis is a prerequisite for graduation in all academic institutions. Higher Education institutions, such as Imam Bonjol Islamic State Institute requires its students to write a thesis in order to graduate. Students write their theses and they were examined before the board of examiners. However, students found it difficult to write ‘good’ theses that show academic honesty and high level of originality. This is a big issue in our institution, this article, therefore examines factors that reduce originality of students’ theses. Having analysed over 10 theses using content analysis method, the authors found that almost all theses contain issues that reduces the originality of the theses. Students frequently commit structural plagiarism, in which they tend to follow the structure of their colleagues’ theses, and only made minor changes. Other finding showed that in stating their research problem, students make a claim without appropriate justification. Issues of referencing and paraphrasing are two important issues that reduce qualities of students’ theses.

The Dragon Project origins, achievements and legacies

International Nuclear Information System (INIS)

Price, M.S.T.

2012-01-01

The lineage of the Dragon Project can be traced back to 1955 when the United Kingdom launched a nuclear power programme which involved the construction of large graphite moderated reactors fuelled with natural uranium and cooled by carbon dioxide. Not long afterwards the European Nuclear Energy Agency (ENEA) of the then newly formed Organisation for European Economic Cooperation (OEEC), in the spirit of the time, sought to encourage the construction of nuclear power stations and the development of joint nuclear undertakings. The United Kingdom Atomic Energy Research Establishment (AERE) had, since 1949, been studying possible long term improvements in energy conversion efficiency resulting from higher coolant gas temperatures and the use of ceramic materials. A 1955 paper on gas-cooled reactors using the U-233/thorium cycle attracted interest and this progressed to the definition of an initial programme. The high temperature work led to a proposal for a 20 MW(Th) Reactor Experiment and one important consequence of the ENEA/OEEC initiative was the setting up in April 1959 of the international Dragon Project Agreement. Initial experiments at Harwell in 1957 had involved the coating of small spheroidal particles of uranium carbide or oxide with pyrolytic carbon which were then bonded with carbonaceous material. But experiments demonstrated that fission products such as caesium, strontium or barium could diffuse through such coatings. This led in 1961 to the modification of the coated particle design by the addition of an intermediate layer of silicon or zirconium carbide. The small size of the particles necessitated a statistical approach to quality during manufacture and effort was concentrated on the minimisation of the broken or defective particle fraction. The subsequent operation of the Dragon Reactor for over 10 years confirmed the benign nature of a HTR. It also proved that fuel bodies made with coated particles were capable of maintaining a high degree of

Origin and neurochemical properties of bulbospinal neurons projecting to the rat lumbar spinal cord via the medal longitudinal fasciculus and caudal ventrolateral medulla

Full Text Available Bulbospinal systems (BS originate from various regions of the brainstem and influence spinal neurons by classical synaptic and modulatory mechanisms. Our aim was to determine the brainstem locations of cells of origin of BS pathways passing through the medial longitudinal fasciculus (MLF and the caudal ventrolateral medulla (CVLM. We also examined the transmitter content of spinal terminations of the CVLM pathway. Six adult rats received Fluorogold (FG injections to the right intermediate grey matter of the lumbar cord (L1-L2 and the b-subunit of cholera toxin (CTb was injected either into the MLF or the right CVLM (3 animals each. Double-labelled cells were identified within brainstem structures with confocal microscopy and mapped onto brainstem diagrams. An additional 3 rats were injected with CTb in the CVLM to label axon terminals in the lumbar spinal cord. Double-labelled cells projecting via the MLF or CVLM were found principally in reticular regions of the medulla and pons but small numbers of cells were also located within the midbrain. CVLM projections to the lumbar cord were almost exclusively ipsilateral and concentrated within the intermediate grey matter. Most (62% of terminals were immunoreactive for the vesicular glutamate transporter 2 while 23% contained the vesicular GABA transporter. The inhibitory subpopulation was glycinergic, GABAergic or contained both transmitters. The proportions of excitatory and inhibitory axons projecting via the CVLM to the lumbar cord are similar to those projecting via the MLF. Unlike the MLF pathway, CVLM projections are predominantly ipsilateral and concentrated within intermediate grey but do not extend into motor nuclei or laminia VIII. Terminations of the CVLM pathway are located in a region of the grey matter that is rich in premotor interneurons; thus its primary function may be to coordinate activity of premotor networks.

Excitatory cortical neurons project to various subcortical and intracortical regions, and exhibit diversity in their axonal connections. Although this diversity may develop from primary axons, how many types of axons initially occur remains unknown. Using a sparse-labeling in utero electroporation method, we investigated the axonal outgrowth of these neurons in mice and correlated the data with axonal projections in adults. Examination of lateral cortex neurons labeled during the main period of cortical neurogenesis (E11.5-E15.5) indicated that axonal outgrowth commonly occurs in the intermediate zone. Conversely, the axonal direction varied; neurons labeled before E12.5 and the earliest cortical plate neurons labeled at E12.5 projected laterally, whereas neurons labeled thereafter projected medially. The expression of Ctip2 and Satb2 and the layer destinations of these neurons support the view that lateral and medial projection neurons are groups of prospective subcortical and callosal projection neurons, respectively. Consistently, birthdating experiments demonstrated that presumptive lateral projection neurons were generated earlier than medial projection neurons, even within the same layer. These results suggest that the divergent axonal connections of excitatory cortical neurons begin from two types of primary axons, which originate from two sequentially generated distinct subpopulations: early-born lateral (subcortical) and later-born medial (callosal) projection neuron groups. © The Author 2015.

Stochastic layer scaling in the two-wire model for divertor tokamaks

Science.gov (United States)

Ali, Halima; Punjabi, Alkesh; Boozer, Allen

2009-06-01

The question of magnetic field structure in the vicinity of the separatrix in divertor tokamaks is studied. The authors have investigated this problem earlier in a series of papers, using various mathematical techniques. In the present paper, the two-wire model (TWM) [Reiman, A. 1996 Phys. Plasmas 3, 906] is considered. It is noted that, in the TWM, it is useful to consider an extra equation expressing magnetic flux conservation. This equation does not add any more information to the TWM, since the equation is derived from the TWM. This equation is useful for controlling the step size in the numerical integration of the TWM equations. The TWM with the extra equation is called the flux-preserving TWM. Nevertheless, the technique is apparently still plagued by numerical inaccuracies when the perturbation level is low, resulting in an incorrect scaling of the stochastic layer width. The stochastic broadening of the separatrix in the flux-preserving TWM is compared with that in the low mn (poloidal mode number m and toroidal mode number n) map (LMN) [Ali, H., Punjabi, A., Boozer, A. and Evans, T. 2004 Phys. Plasmas 11, 1908]. The flux-preserving TWM and LMN both give Boozer-Rechester 0.5 power scaling of the stochastic layer width with the amplitude of magnetic perturbation when the perturbation is sufficiently large [Boozer, A. and Rechester, A. 1978, Phys. Fluids 21, 682]. The flux-preserving TWM gives a larger stochastic layer width when the perturbation is low, while the LMN gives correct scaling in the low perturbation region. Area-preserving maps such as the LMN respect the Hamiltonian structure of field line trajectories, and have the added advantage of computational efficiency. Also, for a $1\\frac12$ degree of freedom Hamiltonian system such as field lines, maps do not give Arnold diffusion.

Origins of Sinuous and Braided Channels on Ascraeus Mons, Mars - A Keck Geology Consortium Undergraduate Research Project

de Wet, A. P.; Bleacher, J. E.; Garry, W. B.

Water has clearly played an important part in the geological evolution of Mars. There are many features on Mars that were almost certainly formed by fluvial processes -- for example, the channels Kasei Valles and Ares Vallis in the Chryse Planitia area of Mars are almost certainly fluvial features. On the other hand, there are many channel features that are much more difficult to interpret -- and have been variously attributed to volcanic and fluvial processes. Clearly unraveling the details of the role of water on Mars is extremely important, especially in the context of the search of extinct or extant life. In this project we built on our recent work in determining the origin of one channel on the southwest rift apron of Ascraeus Mons. This project, funded by the Keck Geology Consortium and involving 4 undergraduate geology majors took advantage of the recently available datasets to map and analyze similar features on Ascraeus Mons and some other areas of Mars. A clearer understanding of how these particular channel features formed might lead to the development of better criteria to distinguish how other Martian channel features formed. Ultimately this might provide us with a better understanding of the role of volcanic and fluvial processes in the geological evolution of Mars.

PIT-tags recovered from tern and cormorant breeding colonies at Rice Island and observations from the interrogation systems at John Day and Bonneville Dams were incorporated into survival analyses. Whether the estimates for the upper reaches of the system, between Lower Granite and McNary Dams were as expected (with weighted averages S{sub LGR-LGS} = 0.996, S{sub LGS-LMN} = 0.837, and S{sub LMN-McN} = 0.941), those for the lower reaches, between John Day and Bonneville Dams, appeared positively biased with survival estimates typically greater than 1. Their weighted averages were S{sub McN-JDA} = 0.707 and S{sub JDA-BON} = 1.792 for 1997 releases. For the 1998 releases, they were S{sub McN-JDA} = 0.795 and S{sub JDA-BON} = 1.312. If the estimates for the lower reaches were biased, the estimates for the whole project would also be biased (S{sub LGR-BON} = 0.819). We determined that bias could have arisen if the terns and cormorants of Rice Island fished for salmon yearlings in waters of the BON-Rice reach at low rates (M{sub BON-Rice} {le} 0.2), and the rates of tag-deposition and tag-detection were low (R{sub D} x R{sub R} {le} 0.4). Moreover, unknown levels of uncensored post-detection mortality and scavenging of previously dead salmon yearlings may have also added to the bias.

Management of delayed nuclear power plant projects

International Nuclear Information System (INIS)

2005-01-01

The IAEA assists the management of organizations responsible for Nuclear Power Plant Projects with significant delays with respect to the originally scheduled commercial operation. Several Member States have Nuclear Power Plant Projects with delays of five or more years with respect to the originally scheduled commercial operation. The degree of conformance with original construction schedules shows large variations due to several issues, including financial, economic and public opinion factors. Solving the special difficulties related with a delayed NPP project is problematic and dependent on the particular country situation. However it is not regarded as an isolated national problem but as a significant issue with a number of difficulties shared by several Member States. The IAEA collects information and supports the management of delayed NPP projects by identifying main common issues, gathering available experience and addressing specific needs. On this background the IAEA is in the position to provide unique impartial assistance based upon best international practices. This enables Member States to maintain readiness for resuming the project construction when the conditions permit and to strengthen management's abilities for the completion of the project. The IAEA's service is tailored to the needs and requirements of the requesting organization, implemented on-site by international experts and addresses areas such as project control measures, human resources, updating to technological and regulatory requirements, project data, nuclear safety review, physical protection and nuclear security and preparation to resume project construction and operation

The Watchdog Project completed 100% of the project Statement of Project Objective (SOPO). The Watchdog project was a very aggressive project looking to accomplish commercialization of technology that had never been commercialized, as a result it took six years to complete not the original three that were planned. No additional federal funds were requested from the original proposal and SEL contributed the additional cost share required to complete the project. The result of the Watchdog Project is the world’s first industrial rated Software Defined Network (SDN) switch commercially available. This technology achieved the SOPOO and DOE Roadmap goals to have strong network access control, improve reliability and network performance, and give the asset owner the ability to minimize attack surface before and during an attack. The Watchdog project is an alliance between CenterPoint Energy Houston Electric, Pacific Northwest National Laboratories (PNNL), and Schweitzer Engineering Laboratories, Inc. (SEL). SEL is the world’s leader in microprocessor-based electronic equipment for protecting electric power systems. PNNL performs basic and applied research to deliver energy, environmental, and national security for our nation. CenterPoint Energy is the third largest publicly traded natural gas delivery company in the U.S and third largest combined electricity and natural gas delivery company. The Watchdog Project efforts were combined with the SDN Project efforts to produce the entire SDN system solution for the critical infrastructure. The Watchdog project addresses Topic Area of Interest 5: Secure Communications, for the DEFOA- 0000359 by protecting the control system local area network itself and the communications coming from and going to the electronic devices on the local network.

The Yucca Mountain Site Characterization Project (YMP) has been involved over the years in the continuing struggle with establishing acceptable Software Quality Assurance (SQA) requirements for the development, modification, and acquisition of computer programs used to support the Mined Geologic Disposal System. These computer programs will be used to produce or manipulate data used directly in site characterization, design, analysis, performance assessment, and operation of repository structures, systems, and components. Scientists and engineers working on the project have claimed that the SQA requirements adopted by the project are too restrictive to allow them to perform their work. This paper will identify the source of the original SQA requirements adopted by the project. It will delineate the approach used by the project to identify concerns voiced by project engineers and scientists regarding the original SQA requirements. It will conclude with a discussion of methods used to address these problems in the rewrite of the original SQA requirements

Alshina, Elena; Zakharchenko, Vladyslav

2017-09-01

Advances in display technologies both for head mounted devices and television panels demand resolution increase beyond 4K for source signal in virtual reality video streaming applications. This poses a problem of content delivery trough a bandwidth limited distribution networks. Considering a fact that source signal covers entire surrounding space investigation reviled that compression efficiency may fluctuate 40% in average depending on origin selection at the conversion stage from 3D space to 2D projection. Based on these knowledge the origin selection algorithm for video compression applications has been proposed. Using discontinuity entropy minimization function projection origin rotation may be defined to provide optimal compression results. Outcome of this research may be applied across various video compression solutions for omnidirectional content.

The Origins of the Acheulean at Olduvai Gorge (Tanzania: A New Paleoanthropological Project in East Africa

Directory of Open Access Journals (Sweden)

Ignacio de la Torre

2012-12-01

Full Text Available The disappearance of the earliest human culture, the Oldowan, and its substitution by a new technology, the Acheulean, is one of the main topics in modern Paleoanthropology. Recent research has established that the Acheulean emerged originally in East Africa around 1.7–1.6 million years ago, and from that area expanded across the rest of Africa, Europe and parts of Asia. Despite the great relevance of the Oldowan-Acheulean transition, little is known about the biological and cultural evolutionary mechanisms underlying this process. Traditionally, it has been assumed that this major cultural change was ignited by the emergence of a new human species, Homo ergaster/erectus, and that there was a steady technological evolution during the Oldowan that eventually led to the emergence of the Acheulean handaxes. However, these assumptions are not grounded in the current available evidence, but rooted in cultural-history paradigms that should now be superseded. Olduvai Gorge (Tanzania is the site where the traditional view of the Oldowan-Acheulean transition was established. The aim of the recently launched Olduvai Geochronology and Archaeology Project is to tackle this question by conducting a comprehensive research program at Olduvai, based on the retrieval of fresh data derived from new laboratory and fieldwork research. The multidisciplinary character of this ongoing study is providing an integrative perspective to the analysis of the paleoecology, archaeology, geology and geochronology of the transition to the Acheulean at Olduvai. Using an innovative theoretical perspective that combines interests in cultural change, ecological adaptations, and biological evolution, and state-of-the-art methods in archaeology, geology and taphonomy, this project aims to make Olduvai one of the world’s best references for the understanding of the evolutionary processes that led to the emergence of the Acheulean, the longest lasting culture in the history of

Planetary Environments and Origins of Life

Ollivier Marc

2014-02-01

Full Text Available The present strategies proposed for the search for the origins of life and for extra-terrestrial life are mainly based on Earth-life and its adaptation along geological eras to the Earth environment. These strategies should however face the difficulty that one cannot as yet accurately date the appearance of life on Earth, and consequently one cannot identify a chronology of phenomena related to the transition from the non-living to the living and the dependence of these phenomena on the Earth environment. In this paper, we present new approaches to search for the origins of life on the Earth and next, for life on exoplanets. This study is based on our experience gained at the head of the CNRSc interdisciplinary research initiative "Environnements Planétaires et Origines de la Vie (EPOVd, and on the analysis of the projects the initiative funded.

Analysis of uses and competitions of water resources or an original dissemination strategy of hydrological modelling results of an EU project ?

Science.gov (United States)

La Jeunesse, Isabelle; Fustec, Klervi; Larrue, Corinne; Trottier, Julie

2010-05-01

We propose to address the question of security threats through an analysis of water uses and competitions in the current situation, on one hand, and in conditions of climate change, on the other hand, in order to have an operational dissemination of hydrological modelling results. This will be carried out for each case study of the EU project CLIMB (7th EU FP). In this particular case, climate change impacts are to be considered in relation with water uses and rivalries. Taking them into account while involving stakeholders should allow us to have a deep impact on water uses regulation under conditions of climate change. The originality of this methodology, the first objective of which within the project is to disseminate project results and interact with stakeholders, is to use the dissemination phase as a means of involving stakeholder knowledge concerning water uses and competitions. The idea is to let the stakeholders identify themselves, in each case study, by means of interactive methods, the impact of the change of hydrological regime on their own water uses and competitions. We propose to use a real "bottom-up" strategy to assess the potential water uses and rivalries in the context of water scarcity (or flood) due to climate change. Such an approach will allow us to evaluate the risk of an increase in water rivalries and threats to security following climate change impacts scenarios at the river basin scale.

PROJECT MANAGEMENT AND RELATIONSHIP MARKETING: INTERSECTIONS FOR STAKEHOLDER MANAGEMENT IN PROJECTS

Full Text Available Projects development is essential for organizations. Among the factors originated in projects that influence performance is quality. This variable must be managed to meet the expectations of the stakeholders and this can only be achieved through effective monitoring and control. It can be seen that relationship marketing is relevant to the competitive reality of contemporary organizations. With the purpose of contributing to organizational studies, this theoretical essay proposes to approach project management in relationship marketing. In the context of integrated management, it is discussed how management action can be applied to engage and involve stakeholders in projects, in order to create value and achieve the expectations sustained by the execution of the projects. Based on the reflection, the quality of relationship management is pointed out as a construct of higher order, composed of at least two dimensions: trust and satisfaction.

Projector primary-based optimization for superimposed projection mappings

Science.gov (United States)

Ahmed, Bilal; Lee, Jong Hun; Lee, Yong Yi; Lee, Kwan H.

2018-01-01

Recently, many researchers have focused on fully overlapping projections for three-dimensional (3-D) projection mapping systems but reproducing a high-quality appearance using this technology still remains a challenge. On top of existing color compensation-based methods, much effort is still required to faithfully reproduce an appearance that is free from artifacts, colorimetric inconsistencies, and inappropriate illuminance over the 3-D projection surface. According to our observation, this is due to the fact that overlapping projections are treated as an additive-linear mixture of color. However, this is not the case according to our elaborated observations. We propose a method that enables us to use high-quality appearance data that are measured from original objects and regenerate the same appearance by projecting optimized images using multiple projectors, ensuring that the projection-rendered results look visually close to the real object. We prepare our target appearances by photographing original objects. Then, using calibrated projector-camera pairs, we compensate for missing geometric correspondences to make our method robust against noise. The heart of our method is a target appearance-driven adaptive sampling of the projection surface followed by a representation of overlapping projections in terms of the projector-primary response. This gives off projector-primary weights to facilitate blending and the system is applied with constraints. These samples are used to populate a light transport-based system. Then, the system is solved minimizing the error to get the projection images in a noise-free manner by utilizing intersample overlaps. We ensure that we make the best utilization of available hardware resources to recreate projection mapped appearances that look as close to the original object as possible. Our experimental results show compelling results in terms of visual similarity and colorimetric error.

Full Text Available Purpose: This work investigates the influence of project managers’ personality on the success of a project in a Multinational Corporation. The methodology proposed for analyzing the project managers’ personality is based on the Myers-Briggs Type Indicator.Design/methodology/approach: Forty projects carried out in 2012 by multinational corporation, concerning new product development (NPD, have been analyzed, comparing the profile of project managers with results obtained in terms of traditional performance indexes (time delay and over-budget of projects and performance indexes usually used in “Lean Production” sector (waste time and type of “wastes”. A detailed analysis of the most important “wastes” during the project development is carried out using the Value Stream Mapping (VSM technique.Findings and Originality/value: Relying on the Myers–Briggs personality instrument, results show that extroverted managers (as opposed to introverted managers carry out projects that show lower delay and lower waste time. Introverted managers often make “Over-processing” and “Defect” types of waste. Moreover, lower delay and over-budget have been shown by perceiving managers.Research limitations: Regarding the limitations of this work it is necessary to highlight that we collected data from project managers in a retrospective way. While we believe that several aspects of our data collection effort helped enhance the accuracy of the results, future research could conduct real-time case study research to get more detailed insights into the proposed relationships and avoid retrospective bias. Moreover we focused on a single respondent, the project manager. This helped us ensure that their interpretations played an important role in product development. But, we cannot examined the opinion of team members that could be different from project managers opinion regarding some questions.Originality/value: This research provides insight useful

Chamera Hydroelectric Project was selected by National Hydroelectric Power Corporation (NHPC) as a pilot project for accelerated development of hydro-power in the country. This project was considered to have certain distinct specialties from different aspects in comparison with other projects. In the first place, the field investigation for the project was completed in a record time of only eight months by deploying the most modern techniques. Secondly, Chamera was the first NHPC project with external aid both technically and financially. The third and most important of all the specialties was in the planned reduction of construction period to 6 years from the original estimate of 8 years. Such reduction of gestation period was considered to be the direct outcome of modern method of management, monitoring and improved imported technology. The investment decision in the project was taken in April '84 with an estimated cost of energy at busbar 44.12 paise/unit exclusive of return on equity capital and royalty payable to the home state. The all inclusive rate of power was estimated 75.86 paise/unit. (author). 4 tabs

The Romeu pluton, NE Portugal: constraints on the origin of leucogranite

Wallfass, C.M.

1987-01-01

This the petrogenesis of the Romeu leucogranites can be satisfactorily explained by a fractionation model in which an original granite magma produced a leucogranites rest melt. The S-type characteristics of the leucogranites (high paraluminicity, high initial Sr isotope ratio and the pattern of trace element enrichment and depletion) follow from this model. Research within the Ibergranite Project show that the granite magmas derive from earlier mets, wich descendent from gabbro melts, ultimately originating in the matle. It is possible that the original magma was contaminated with crustal rocks during its residence in the lower crust, but these leucogranites are uncontaminated high level fractionates. (C.D.G.) [pt

Gordon Craig's Scene Project: a history open to revision

Full Text Available The article proposes a review of Gordon Craig’s Scene project, an invention patented in 1910 and developed until 1922. Craig himself kept an ambiguous position whether it was an unfulfilled project or not. His son and biographer Edward Craig sustained that Craig’s original aims were never achieved because of technical limitation, and most of the scholars who examined the matter followed this position. Departing from the actual screen models saved in the Bibliothèque Nationale de France, Craig’s original notebooks, and a short film from 1963, I defend that the patented project and the essay published in 1923 mean, indeed, the materialisation of the dreamed device of the thousand scenes in one scene

This project is in support of our national goal to reduce our dependence on fossil fuels. By supporting efforts that contribute toward the successful mass production of plug-in hybrid electric vehicles, our nation’s transportation-related fuel consumption can be offset with energy from the grid. Over four and a half years ago, when this project was originally initiated, plug-in electric vehicles were not readily available in the mass marketplace. Through the creation of a 21 unit plug-in hybrid vehicle fleet, this program was designed to demonstrate the feasibility of the technology and to help build cross-industry familiarity with the technology and interface of this technology with the grid. Ford Escape PHEV Demonstration Fleet 3 March 26, 2014 Since then, however, plug-in vehicles have become increasingly more commonplace in the market. Ford, itself, now offers an all-electric vehicle and two plug-in hybrid vehicles in North America and has announced a third plug-in vehicle offering for Europe. Lessons learned from this project have helped in these production vehicle launches and are mentioned throughout this report. While the technology of plugging in a vehicle to charge a high voltage battery with energy from the grid is now in production, the ability for vehicle-to-grid or bi-directional energy flow was farther away than originally expected. Several technical, regulatory and potential safety issues prevented progressing the vehicle-to-grid energy flow (V2G) demonstration and, after a review with the DOE, V2G was removed from this demonstration project. Also proving challenging were communications between a plug-in vehicle and the grid or smart meter. While this project successfully demonstrated the vehicle to smart meter interface, cross-industry and regulatory work is still needed to define the vehicle-to-grid communication interface.

Phenomenology in Its Original Sense.

Science.gov (United States)

van Manen, Max

2017-05-01

In this article, I try to think through the question, "What distinguishes phenomenology in its original sense?" My intent is to focus on the project and methodology of phenomenology in a manner that is not overly technical and that may help others to further elaborate on or question the singular features that make phenomenology into a unique qualitative form of inquiry. I pay special attention to the notion of "lived" in the phenomenological term "lived experience" to demonstrate its critical role and significance for understanding phenomenological reflection, meaning, analysis, and insights. I also attend to the kind of experiential material that is needed to focus on a genuine phenomenological question that should guide any specific research project. Heidegger, van den Berg, and Marion provide some poignant exemplars of the use of narrative "examples" in phenomenological explorations of the phenomena of "boredom," "conversation," and "the meaningful look in eye-contact." Only what is given or what gives itself in lived experience (or conscious awareness) are proper phenomenological "data" or "givens," but these givens are not to be confused with data material that can be coded, sorted, abstracted, and accordingly analyzed in some "systematic" manner. The latter approach to experiential research may be appropriate and worthwhile for various types of qualitative inquiry but not for phenomenology in its original sense. Finally, I use the mythical figure of Kairos to show that the famous phenomenological couplet of the epoché-reduction aims for phenomenological insights that require experiential analysis and attentive (but serendipitous) methodical inquiry practices.

The origins of originality: the neural bases of creative thinking and originality.

Science.gov (United States)

Shamay-Tsoory, S G; Adler, N; Aharon-Peretz, J; Perry, D; Mayseless, N

2011-01-01

Although creativity has been related to prefrontal activity, recent neurological case studies postulate that patients who have left frontal and temporal degeneration involving deterioration of language abilities may actually develop de novo artistic abilities. In this study, we propose a neural and cognitive model according to which a balance between the two hemispheres affects a major aspect of creative cognition, namely, originality. In order to examine the neural basis of originality, that is, the ability to produce statistically infrequent ideas, patients with localized lesions in the medial prefrontal cortex (mPFC), inferior frontal gyrus (IFG), and posterior parietal and temporal cortex (PC), were assessed by two tasks involving divergent thinking and originality. Results indicate that lesions in the mPFC involved the most profound impairment in originality. Furthermore, precise anatomical mapping of lesions indicated that while the extent of lesion in the right mPFC was associated with impaired originality, lesions in the left PC were associated with somewhat elevated levels of originality. A positive correlation between creativity scores and left PC lesions indicated that the larger the lesion is in this area the greater the originality. On the other hand, a negative correlation was observed between originality scores and lesions in the right mPFC. It is concluded that the right mPFC is part of a right fronto-parietal network which is responsible for producing original ideas. It is possible that more linear cognitive processing such as language, mediated by left hemisphere structures interferes with creative cognition. Therefore, lesions in the left hemisphere may be associated with elevated levels of originality. Copyright © 2010 Elsevier Ltd. All rights reserved.

Learning binary code via PCA of angle projection for image retrieval

Science.gov (United States)

Yang, Fumeng; Ye, Zhiqiang; Wei, Xueqi; Wu, Congzhong

2018-01-01

With benefits of low storage costs and high query speeds, binary code representation methods are widely researched for efficiently retrieving large-scale data. In image hashing method, learning hashing function to embed highdimensions feature to Hamming space is a key step for accuracy retrieval. Principal component analysis (PCA) technical is widely used in compact hashing methods, and most these hashing methods adopt PCA projection functions to project the original data into several dimensions of real values, and then each of these projected dimensions is quantized into one bit by thresholding. The variances of different projected dimensions are different, and with real-valued projection produced more quantization error. To avoid the real-valued projection with large quantization error, in this paper we proposed to use Cosine similarity projection for each dimensions, the angle projection can keep the original structure and more compact with the Cosine-valued. We used our method combined the ITQ hashing algorithm, and the extensive experiments on the public CIFAR-10 and Caltech-256 datasets validate the effectiveness of the proposed method.

Coordinated Regulation of the EIIMan and fruRKI Operons of Streptococcus mutans by Global and Fructose-Specific Pathways.

Zeng, Lin; Chakraborty, Brinta; Farivar, Tanaz; Burne, Robert A

2017-11-01

The glucose/mannose-phosphotransferase system (PTS) permease EII Man encoded by manLMN in the dental caries pathogen Streptococcus mutans has a dominant influence on sugar-specific, CcpA-independent catabolite repression (CR). Mutations in manL affect energy metabolism and virulence-associated traits, including biofilm formation, acid tolerance, and competence. Using promoter::reporter fusions, expression of the manLMN and the fruRKI operons, encoding a transcriptional regulator, a fructose-1-phosphate kinase and a fructose-PTS permease EII Fru , respectively, was monitored in response to carbohydrate source and in mutants lacking CcpA, FruR, and components of EII Man Expression of genes for EII Man and EII Fru was directly regulated by CcpA and CR, as evinced by in vivo and in vitro methods. Unexpectedly, not only was the fruRKI operon negatively regulated by FruR, but also so was manLMN Carbohydrate transport by EII Man had a negative influence on expression of manLMN but not fruRKI In agreement with the proposed role of FruR in regulating these PTS operons, loss of fruR or fruK substantially altered growth on a number of carbohydrates, including fructose. RNA deep sequencing revealed profound changes in gene regulation caused by deletion of fruK or fruR Collectively, these findings demonstrate intimate interconnection of the regulation of two major PTS permeases in S. mutans and reveal novel and important contributions of fructose metabolism to global regulation of gene expression. IMPORTANCE The ability of Streptococcus mutans and other streptococcal pathogens to survive and cause human diseases is directly dependent upon their capacity to metabolize a variety of carbohydrates, including glucose and fructose. Our research reveals that metabolism of fructose has broad influences on the regulation of utilization of glucose and other sugars, and mutants with changes in certain genes involved in fructose metabolism display profoundly different abilities to grow and

Naesliden project: FEM modelling strategies

Energy Technology Data Exchange (ETDEWEB)

Borg, T.

1980-05-15

A schematized description is given of the different stages in the project. The aim is to show the development of the project and the strategies which have been chosen. The four different stages in the project are treated from the following points of view: the reasons for the choice of material models; the determination of model properties; and the control of the calculated values. In the origin plan for the project it was stated to only use a joint element model. However, it was shown to be a reasonable strategy to use both a general linear elastic model and a geometric restricted model with joint elements. During the course of the Project's development stages, it was found that a reduction in the number of rock types could be made without loss of generality. A modified strategy is suggested based on more studies of the rock bahavior and less advanced calculations in the first stages of the project.

The primate cingulate gyrus contains multiple cortical areas that can be distinguished by several neurochemical features, including the distribution of neurofilament protein-enriched pyramidal neurons. In addition, connectivity and functional properties indicate that there are multiple motor areas in the cortex lining the cingulate sulcus. These motor areas were targeted for analysis of potential interactions among regional specialization, connectivity, and cellular characteristics such as neurochemical profile and morphology. Specifically, intracortical injections of retrogradely transported dyes and intracellular injection were combined with immunocytochemistry to investigate neurons projecting from the cingulate motor areas to the putative forelimb region of the primary motor cortex, area M1. Two separate groups of neurons projecting to area M1 emanated from the cingulate sulcus, one anterior and one posterior, both of which furnished commissural and ipsilateral connections with area M1. The primary difference between the two populations was laminar origin, with the anterior projection originating largely in deep layers, and the posterior projection taking origin equally in superficial and deep layers. With regard to cellular morphology, the anterior projection exhibited more morphologic diversity than the posterior projection. Commissural projections from both anterior and posterior fields originated largely in layer VI. Neurofilament protein distribution was a reliable tool for localizing the two projections and for discriminating between them. Comparable proportions of the two sets of projection neurons contained neurofilament protein, although the density and distribution of the total population of neurofilament protein-enriched neurons was very different in the two subareas of origin. Within a projection, the participating neurons exhibited a high degree of morphologic heterogeneity, and no correlation was observed between somatodendritic morphology and

Management of delayed nuclear power plant projects

NONE

1999-09-01

According to the available information at the IAEA PRIS (Power Reactor Information System) at the end of 1998 there were more than 40 nuclear power plant projects with delays of five or more years with respect to the originally scheduled commercial operation. The degree of conformance with original construction schedules showed large variations due to several issues, including financial, economic and public opinion factors. Taking into account the number of projects with several years delay in their original schedules, it was considered useful to identify the subject areas where exchange of experience among Member States would be mutually beneficial in identification of problems and development of guidance for successful management of the completion of these delayed projects. A joint programme of the IAEA Departments of Nuclear Energy (Nuclear Power Engineering Section) and Technical Co-operation (Europe Section, with additional support from the Latin America and West Asia Sections) was set up during the period 1997-1998. The specific aim of the programme was to provide assistance in the management of delayed nuclear power plants regarding measures to maintain readiness for resuming the project implementation schedule when the conditions permit. The integration of IAEA interdepartmental resources enabled the participation of 53 experts from 14 Member States resulting in a wider exchange of experience and dissemination of guidance. Under the framework of the joint programme, senior managers directly responsible for delayed nuclear power plant projects identified several issues or problem areas that needed to be addressed and guidance on management be provided. A work plan for the development of several working documents, addressing the different issues, was established. Subsequently these documents were merged into a single one to produce the present publication.

Updegraff, Kimberly A; Umaña-Taylor, Adriana J

2015-06-01

Mexican-origin families are a large and rapidly increasing subgroup of the U.S. population, but they remain underrepresented in family scholarship. This paper introduces a special section of four papers on Mexican-origin families designed to contribute to the advancement of research on how cultural, family, and gender socialization processes unfold across key developmental periods and life transitions in this cultural context. Two longitudinal studies of Mexican-origin families provided the data for these four papers: (a) The Juntos Project, an 8-year longitudinal study of mothers, fathers, and adolescent sibling pairs in 246 Mexican-origin families; and (b) The Supporting MAMI Project, a study following 204 adolescent mothers and their mother figures from the third trimester of pregnancy through their young children's 5th birthdays. In this introductory paper, we highlight four themes, including (a) differential acculturation and reciprocal socialization, (b) interdependence in families, (c) the intersection of culture and gender, and (d) methodological issues. We end with suggestions for future research. © 2015 Family Process Institute.

A Bayesian Perspective on the Reproducibility Project: Psychology.

Science.gov (United States)

Etz, Alexander; Vandekerckhove, Joachim

2016-01-01

We revisit the results of the recent Reproducibility Project: Psychology by the Open Science Collaboration. We compute Bayes factors-a quantity that can be used to express comparative evidence for an hypothesis but also for the null hypothesis-for a large subset (N = 72) of the original papers and their corresponding replication attempts. In our computation, we take into account the likely scenario that publication bias had distorted the originally published results. Overall, 75% of studies gave qualitatively similar results in terms of the amount of evidence provided. However, the evidence was often weak (i.e., Bayes factor studies (64%) did not provide strong evidence for either the null or the alternative hypothesis in either the original or the replication, and no replication attempts provided strong evidence in favor of the null. In all cases where the original paper provided strong evidence but the replication did not (15%), the sample size in the replication was smaller than the original. Where the replication provided strong evidence but the original did not (10%), the replication sample size was larger. We conclude that the apparent failure of the Reproducibility Project to replicate many target effects can be adequately explained by overestimation of effect sizes (or overestimation of evidence against the null hypothesis) due to small sample sizes and publication bias in the psychological literature. We further conclude that traditional sample sizes are insufficient and that a more widespread adoption of Bayesian methods is desirable.

Risk variables in evaluation of transport projects

2017-09-01

Depending on the constantly increasing demands on assessment of investment projects, especially assessment of large-scale projects in transport and important European projects with wide impacts, there is constantly increasing focus on risk management, whether to find mitigations, creating corrective measures or their implementation in assessment, especially in the context of Cost-Benefit analysis. To project assessment is often used implementation of certain risk variables, which can generate negative impacts of project outputs in framework of assess. Especially in case of transportation infrastructure projects is taken much emphasis on the influence of risk variables. However, currently in case of assessment of transportation projects is in Czech Republic used a few risk variables, which occur in the most projects. This leads to certain limitation in framework of impact assessment of risk variables. This papers aims to specify a new risk variables and process of applying them to already executed project assessment. Based on changes generated by new risk variables will be evaluated differences between original and adapted assessment.

Color correction of projected image on color-screen for mobile beam-projector

Science.gov (United States)

Son, Chang-Hwan; Sung, Soo-Jin; Ha, Yeong-Ho

2008-01-01

With the current trend of digital convergence in mobile phones, mobile manufacturers are researching how to develop a mobile beam-projector to cope with the limitations of a small screen size and to offer a better feeling of movement while watching movies or satellite broadcasting. However, mobile beam-projectors may project an image on arbitrary surfaces, such as a colored wall and paper, not on a white screen mainly used in an office environment. Thus, color correction method for the projected image is proposed to achieve good image quality irrespective of the surface colors. Initially, luminance values of original image transformed into the YCbCr space are changed to compensate for spatially nonuniform luminance distribution of arbitrary surface, depending on the pixel values of surface image captured by mobile camera. Next, the chromaticity values for each surface and white-screen image are calculated using the ratio of the sum of three RGB values to one another. Then their chromaticity ratios are multiplied by converted original image through an inverse YCbCr matrix to reduce an influence of modulating the appearance of projected image due to spatially different reflectance on the surface. By projecting corrected original image on a texture pattern or single color surface, the image quality of projected image can be improved more, as well as that of projected image on white screen.

Co-delivery of a laminin-111 supplemented hyaluronic acid based hydrogel with minced muscle graft in the treatment of volumetric muscle loss injury.

Directory of Open Access Journals (Sweden)

Stephen M Goldman

Full Text Available Minced muscle autografting mediates de novo myofiber regeneration and promotes partial recovery of neuromuscular strength after volumetric muscle loss injury (VML. A major limitation of this approach is the availability of sufficient donor tissue for the treatment of relatively large VMLs without inducing donor site morbidity. This study evaluated a laminin-111 supplemented hyaluronic acid based hydrogel (HA+LMN as a putative myoconductive scaffolding to be co-delivered with minced muscle grafts. In a rat tibialis anterior muscle VML model, delivery of a reduced dose of minced muscle graft (50% of VML defect within HA+LMN resulted in a 42% improvement of peak tetanic torque production over unrepaired VML affected limbs. However, the improvement in strength was not improved compared to a 50% minced graft-only control group. Moreover, histological analysis revealed that the improvement in in vivo functional capacity mediated by minced grafts in HA+LMN was not accompanied by a particularly robust graft mediated regenerative response as determined through donor cell tracking of the GFP+ grafting material. Characterization of the spatial distribution and density of macrophage and satellite cell populations indicated that the combination therapy damps the heightened macrophage response while re-establishing satellite content 14 days after VML to a level consistent with an endogenously healing ischemia-reperfusion induced muscle injury. Moreover, regional analysis revealed that the combination therapy increased satellite cell density mostly in the remaining musculature, as opposed to the defect area. Based on the results, the following salient conclusions were drawn: 1 functional recovery mediated by the combination therapy is likely due to a superposition of de novo muscle fiber regeneration and augmented repair of muscle fibers within the remaining musculature, and 2 The capacity for VML therapies to augment regeneration and repair within the

Primary melanocytic neoplasms are rare in the pediatric age. Among them, the pattern of neoplastic meningitis represents a peculiar diagnostic challenge since neuroradiological features may be subtle and cerebrospinal fluid analysis may not be informative. Clinical misdiagnosis of neoplastic meningitis with tuberculous meningitis has been described in few pediatric cases, leading to a significant delay in appropriate management of patients. We describe the case of a child with primary leptomeningeal melanoma (LMM) that was initially misdiagnosed with tuberculous meningitis. We review the clinical and molecular aspects of LMM and discuss on clinical and diagnostic implications. A 27-month-old girl with a 1-week history of vomiting with mild intermittent strabismus underwent Magnetic Resonance Imaging, showing diffuse brainstem and spinal leptomeningeal enhancement. Cerebrospinal fluid analysis was unremarkable. Antitubercular treatment was started without any improvement. A spinal intradural biopsy was suggestive for primary leptomeningeal melanomatosis. Chemotherapy was started, but general clinical conditions progressively worsened and patient died 11 months after diagnosis. Molecular investigations were performed post-mortem on tumor tissue and revealed absence of BRAF V600E , GNAQ Q209 and GNA11 Q209 mutations but the presence of a NRAS Q61K mutation. Our case adds some information to the limited experience of the literature, confirming the presence of the NRAS Q61K mutation in children with melanomatosis. To our knowledge, this is the first case of leptomeningeal melanocytic neoplasms (LMN) without associated skin lesions to harbor this mutation. Isolated LMN presentation might be insidious, mimicking tuberculous meningitis, and should be suspected if no definite diagnosis is possible or if antitubercular treatment does not result in dramatic clinical improvement. Leptomeningeal biopsy should be considered, not only to confirm diagnosis of LMN but also to study

PACTEL OECD project planning (PACO). PACTEL OECD project planning

Kouhia, V.; Purhonen, H. [Lappeenranta University of Technology (Finland)

2004-07-01

OECD launched the SETH project to investigate issues relevant for accident prevention and management and to ensure the existence of integral thermal hydraulic test facilities. The facilities included in the SETH project are PKL from Germany and PANDA from Switzerland. At the early stages of the SETH project an idea was raised to exploit the PACTEL facility in a similar OECD project. Without any external funding the analytical work in the required extent would not be possible within Lappeenranta University of Technology, the party responsible of operating PACTEL. This fact directed the PACO project proposal to be conducted for the SAFIR programme. The aim of the PACO project is to prepare a project proposal to OECD of a PACTEL related project. To attain this objective some preliminary analyses have to be performed to ensure the relevancy of the proposed topic. The low power situation, i.e. midloop state was chosen to be the topic in the PACO studies and project planning basis. The plan is to use PACTEL to examine vertical steam generator behaviour during the midloop operation and the following loss of residual heat removal system transient. Such a possibility is acknowledged with special alterations to PACTEL. The APROS code version 5.04.07 was selected as a tool for the preanalyses. The virtual simulation of the chosen experimental situation would give a preconception on the phenomena to be expected and the progression of the transient. Originally the PACO project was planned to continue only for a few months, ending up with the project proposal to OECD during the summer time 2004. During the pre-calculation process it became obvious that the time expected was not enough to establish good pre-calculation results. The reasons for this relates to time used to learn and adapt the use of the chosen code, improvements and corrections in modelling as well as the code ability to manage the special conditions defined for the project topic.

Full Text Available This article analyses the different models of businesswomen of Asian origin in Spain. To that end, the author considers both the family variable in the migration project and the individual’s own personal project. These variables, in turn, combine with others, such as the businesswomen’s position in the family and the stage of the migration project in which they find themselves. As a result, the author defines four profiles: 1 family businesswomen; 2 women who market their own work; 3 daughters of business families; 4 daughters of the diaspora. Furthermore, a transversal element also exists among all the female entrepreneurs: the use of the “ethnic” as a business asset.

In this paper, we propose a modification for the CQ algorithm, which computes the stepsize adaptively and performs an additional projection step onto two half-spaces in each iteration. We further propose a relaxation scheme for the self-adaptive projection algorithm by using projections onto half-spaces instead of those onto the original convex sets, which is much more practical. Weak convergence results for both algorithms are analyzed.

Karunakaran, P.; Abdullah, A. H.; Nagapan, S.; Sohu, S.; Kasvar, K. K.

2018-04-01

Cost overrun has been severely hit down the economy and reputations for many construction industry around the world. Many project management tools developed to control the budget of a project. However, the cost management is still considered poor as there are many cost overrun issues occurred in the construction industry. Thus, this paper aims to identify and cluster the potential construction project cost overrun factors according to their originating groups using the thematic approach. Basically, through literature review, all the potential factors that may cause cost overrun were screened thoroughly before they were clustered into seven (7) groups of the originating factors, namely project, contract, client, contractor, consultant, labour and external. Each potential factor was explained clearly with some examples based on the Malaysian case studies to illustrate the cost overrun scenario. These findings may aid in the future to highlight on how to mitigate the critical potential factors of cost overrun to reduce or overcome its impact on all the stakeholders involved.

Measures which host countries and countries of origin could adopt to promote the return of migrants.

Science.gov (United States)

Debart, M H

1986-03-01

The immigration wave in the 1960s and 1970s brought scores of migrants to Europe. Most intended to work a few years in a foreign country and return to their homeland; however, poor economies in their own countries discouraged their return. At the same time, jobs became scarcer in their host countries. Several European countries today are resorting to measures designed to promote the return of migrants to their countries of origin. This paper outlines the two major options open to governments in their reintegration efforts. Option 1 requires instituting a definite reintegration policy. Public aid to promote reintegration may be provided. For example, the French give aid contingent upon the return of foreign workers in the labor force to the country of origin and not just upon their departure from the host country. Classical methods pay conpensation to the foreign worker; the problem then is to determine at what point to limit the funds. It must be decided whether or not unemployment benefits should be capitalized and whether or not to reimburse social security and old age contributions. It is also desirable for foreign workers to have access to a specialized organization which is able to advise them on setting up a project or business on their return; ideally, this organization should finance the project. Perhaps the best solution is to enlist participation of the governments of the countries of origin to make job openings known to their nationals desiring to return. Option 2 requires that reintegration be introduced into other economic and social programs. Returning foreign workers would be included as a factor in overall policy planning. Vocational training for return migrants could be proposed to job seekers as well as to dismissed workers. A portion of money used to finance housing projects could be earmarked for construction or reservation of housing in the country of origin. Bilateral vocational training programs can be addressed to nationals who want to

Assessment and financing of electric power projects

The aim of the appraisal of a project is to examine the economic need which a project is designed to meet, to judge whether the project is likely to meet this need in an efficient way, and to conclude what conditions should be attached to eventual Bank financing. Bank involvement continues throughout the life of the project helping to ensure that each project is carried out at the least possible cost and that it makes the expected contribution to the country's development. This paper gives an idea about the origin, nature and functions of the World Bank Group, describes the criteria used by the Bank in its power project appraisals, discusses the Bank's views on nuclear power, and concludes with a review of past lending and probable future sources of financing of electrical expansion in the less developed countries.

Involving students in state-of-the-art research from an early age eliminates the idea that science is only for the scientists and empowers young people to explore STEM (Science, Technology, Engineering and Maths) subjects. It is also a great opportunity to dispel harmful stereotypes about who is suitable for STEM careers, while leaving students feeling engaged in modern science and the scientific method. As part of the Twinkle Space Mission’s educational programme, EduTwinkle, students between the ages of 15 and 18 have been performing original research associated with the exploration of space since January 2016. The student groups have each been led by junior researchers—PhD and post-doctoral scientists—who themselves benefit substantially from the opportunity to supervise and manage a research project. This research aims to meet a standard for publication in peer-reviewed journals. At present the research of two ORBYTS teams have been published, one in the Astrophysical Journal Supplement Series and another in JQSRT; we expect more papers to follow. Here we outline the necessary steps for a productive scientific collaboration with school children, generalising from the successes and downfalls of the pilot ORBYTS projects.

The Crossed Projection to the Striatum in Two Species of Monkey and in Humans: Behavioral and Evolutionary Significance.

Innocenti, Giorgio M; Dyrby, Tim B; Andersen, Kasper Winther; Rouiller, Eric M; Caminiti, Roberto

2017-06-01

The corpus callosum establishes the anatomical continuity between the 2 hemispheres and coordinates their activity. Using histological tracing, single axon reconstructions, and diffusion tractography, we describe a callosal projection to n caudatus and putamen in monkeys and humans. In both species, the origin of this projection is more restricted than that of the ipsilateral projection. In monkeys, it consists of thin axons (0.4-0.6 µm), appropriate for spatial and temporal dispersion of subliminal inputs. For prefrontal cortex, contralateral minus ipsilateral delays to striatum calculated from axon diameters and conduction distance are <2 ms in the monkey and, by extrapolation, <4 ms in humans. This delay corresponds to the performance in Poffenberger's paradigm, a classical attempt to estimate central conduction delays, with a neuropsychological task. In both species, callosal cortico-striatal projections originate from prefrontal, premotor, and motor areas. In humans, we discovered a new projection originating from superior parietal lobule, supramarginal, and superior temporal gyrus, regions engaged in language processing. This projection crosses in the isthmus the lesion of which was reported to dissociate syntax and prosody. The projection might originate from an overproduction of callosal projections in development, differentially pruned depending on species. © The Author 2016. Published by Oxford University Press.

Project mobilisation

International Nuclear Information System (INIS)

Clark, J.; Limbrick, A.

1996-01-01

This paper identifies and reviews the issues to be addressed and the procedures to be followed during the mobilisation of projects using LFG as an energy source. Knowledge of the procedures involved in project mobilisation, their sequence and probable timescales, is essential for efficient project management. It is assumed that the majority of projects will be situated on existing, licensed landfill sites and, in addition to complying with the relevant conditions of the waste management licence and original planning consent, any proposed developments on the site will require a separate planning consent. Experience in the UK indicates that obtaining planning permission rarely constitutes a barrier to the development of schemes for the utilisation of LFG. Even so, an appreciation of the applicable environmental and planning legislation is essential as this will enable the developer to recognise the main concerns of the relevant planning authority at an early stage of the project, resulting in the preparation of an informed and well-structured application for planning permission. For a LFG utilisation scheme on an existing landfill site, the need to carry out an environmental assessment (EA) as part of the application for planning permission will, in vitually all cases, be discretionary. Even if not deemed necessary by the planning authority, an EA is a useful tool at the planning application stage, to identify and address potential problems and to support discussions with bodies such as the Environment Agency, from whom consents or authorisations may be required. Carrying out an EA can thus provide for more cost-effective project development and enhanced environmental protection. Typically, the principal contractual arrangements, such as the purchase of gas or the sale of electricity, will have been established before the project mobilisation phase. However, there are many other contractural arrangements that must be established, and consents and permits that may be

We show how auxiliary subspaces and related projectors may be used for preconditioning nonsymmetric system of linear equations. It is shown that preconditioned in such a way (or projected) system is better conditioned than original system (at least if the coefficient matrix of the system to be solved is symmetrizable). Two approaches for solving projected system are outlined. The first one implies straightforward computation of the projected matrix and consequent using some direct or iterative method. The second approach is the projection preconditioning of conjugate gradient-type solver. The latter approach is developed here in context with biconjugate gradient iteration and some related Lanczos-type algorithms. Some possible particular choices of auxiliary subspaces are discussed. It is shown that one of them is equivalent to using colorings. Some results of numerical experiments are reported.

One of the key aspects of creativity is the ability to produce original ideas. Originality is defined in terms of the novelty and rarity of an idea and is measured by the infrequency of the idea compared to other ideas. In the current study we focused on divergent thinking (DT) - the ability to produce many alternate ideas - and assessed the neural pathways associated with originality. Considering that generation of original ideas involves both the ability to generate new associations and the ability to overcome automatic common responses, we hypothesized that originality would be associated with activations in regions related to associative thinking, including areas of the default mode network (DMN) such as medial prefrontal areas, as well as with areas involved in cognitive control and inhibition. Thirty participants were scanned while performing a DT task that required the generation of original uses for common objects. The results indicate that the ability to produce original ideas is mediated by activity in several regions that are part of the DMN including the medial prefrontal cortex (mPFC) and the posterior cingulate cortex (PCC). Furthermore, individuals who are more original exhibited enhanced activation in the ventral anterior cingulate cortex (vACC), which was also positively coupled with activity in the left occipital-temporal area. These results are in line with the dual model of creativity, according to which original ideas are a product of the interaction between a system that generates ideas and a control system that evaluates these ideas.

Tools for Closure Project and Contract Management: Development of the Rocky Flats Integrated Closure Project Baseline

International Nuclear Information System (INIS)

Gelles, C. M.; Sheppard, F. R.

2002-01-01

This paper details the development of the Rocky Flats Integrated Closure Project Baseline - an innovative project management effort undertaken to ensure proactive management of the Rocky Flats Closure Contract in support of the Department's goal for achieving the safe closure of the Rocky Flats Environmental Technology Site (RFETS) in December 2006. The accelerated closure of RFETS is one of the most prominent projects within the Department of Energy (DOE) Environmental Management program. As the first major former weapons plant to be remediated and closed, it is a first-of-kind effort requiring the resolution of multiple complex technical and institutional challenges. Most significantly, the closure of RFETS is dependent upon the shipment of all special nuclear material and wastes to other DOE sites. The Department is actively working to strengthen project management across programs, and there is increasing external interest in this progress. The development of the Rocky Flats Integrated Closure Project Baseline represents a groundbreaking and cooperative effort to formalize the management of such a complex project across multiple sites and organizations. It is original in both scope and process, however it provides a useful precedent for the other ongoing project management efforts within the Environmental Management program

2012-10-01

The Expanded Very Large Array Project, begun in 2001, is now completed -- on time, on budget, and ``on spec.'' The major goal of the project was to multiply the key observational capabilities of the Very Large Array -- the world's most powerful, versatile, and productive radio telescope -- by a factor of at least an order of magnitude by implementation of modern technologies. The result of the project is an operationally new telescope -- renamed the Jansky Very Large Array -- which is capable of new science unimagined in 1980, when the original VLA was completed. In this talk, I will review the goals of the project, and describe the new capabilities of the Jansky Very Large Array. Already, the array is providing fabulous new insights into the physics of the universe,and I will spend the majority of the time describing examples of new results.

Milbredt, Sarah; Farmani, Neda; Sobetzko, Patrick; Waldminghaus, Torsten

2016-10-21

The standard outline of bacterial genomes is a single circular chromosome with a single replication origin. From the bioengineering perspective, it appears attractive to extend this basic setup. Bacteria with split chromosomes or multiple replication origins have been successfully constructed in the last few years. The characteristics of these engineered strains will largely depend on the respective DNA replication patterns. However, the DNA replication has not been investigated systematically in engineered bacteria with multiple origins or split replicons. Here we fill this gap by studying a set of strains consisting of (i) E. coli strains with an extra copy of the native replication origin (oriC), (ii) E. coli strains with an extra copy of the replication origin from the secondary chromosome of Vibrio cholerae (oriII), and (iii) a strain in which the E. coli chromosome is split into two linear replicons. A combination of flow cytometry, microarray-based comparative genomic hybridization (CGH), and modeling revealed silencing of extra oriC copies and differential timing of ectopic oriII copies compared to the native oriC. The results were used to derive construction rules for future multiorigin and multireplicon projects.

Time-Frequency Analysis and Hermite Projection Method Applied to Swallowing Accelerometry Signals

Directory of Open Access Journals (Sweden)

Ervin Sejdić

2010-01-01

Full Text Available Fast Hermite projections have been often used in image-processing procedures such as image database retrieval, projection filtering, and texture analysis. In this paper, we propose an innovative approach for the analysis of one-dimensional biomedical signals that combines the Hermite projection method with time-frequency analysis. In particular, we propose a two-step approach to characterize vibrations of various origins in swallowing accelerometry signals. First, by using time-frequency analysis we obtain the energy distribution of signal frequency content in time. Second, by using fast Hermite projections we characterize whether the analyzed time-frequency regions are associated with swallowing or other phenomena (vocalization, noise, bursts, etc.. The numerical analysis of the proposed scheme clearly shows that by using a few Hermite functions, vibrations of various origins are distinguishable. These results will be the basis for further analysis of swallowing accelerometry to detect swallowing difficulties.

The Cordoba and Wolsung projects: a progress report

International Nuclear Information System (INIS)

Brooks, G.L.

1977-06-01

The Cordoba and Wolsung projects mark the entry into the international sales arena of the standardized Canadian 600 MWe CANDU-PHW reactor design. The Cordoba station experienced a setback in the early stages when severe inflation in Argentina led to a renegotiation of the contract. However, following this, good progress has been made and the current forecast completion date in 1980 is expected to be achieved. The Wolsung project experienced difficulties early in the project due to site conditions, so that site work commenced some 9-10 months later than originally planned. These difficulties had predictable effects upon the progress of site-related engineering and it is expected that the project completion date will be somewhat delayed

Ipsilateral corticotectal projections from the primary, premotor and supplementary motor cortical areas in adult macaque monkeys: a quantitative anterograde tracing study

Science.gov (United States)

Fregosi, Michela; Rouiller, Eric M.

2018-01-01

The corticotectal projection from cortical motor areas is one of several descending pathways involved in the indirect control of spinal motoneurons. In non-human primates, previous studies reported that cortical projections to the superior colliculus originated from the premotor cortex and the primary motor cortex, whereas no projection originated from the supplementary motor area. The aim of the present study was to investigate and compare the properties of corticotectal projections originating from these three cortical motor areas in intact adult macaques (n=9). The anterograde tracer BDA was injected into one of these cortical areas in each animal. Individual axonal boutons, both en passant and terminaux, were charted and counted in the different layers of the ipsilateral superior colliculus. The data confirmed the presence of strong corticotectal projections from the premotor cortex. A new observation was that strong corticotectal projections were also found to originate from the supplementary motor area (its proper division). The corticotectal projection from the primary motor cortex was quantitatively less strong than that from either the premotor or supplementary motor areas. The corticotectal projection from each motor area was directed mainly to the deep layer of the superior colliculus, although its intermediate layer was also a consistent target of fairly dense terminations. The strong corticotectal projections from non-primary motor areas are in position to influence the preparation and planning of voluntary movements. PMID:28921678

Full Text Available Several semantic and syntactic distinctions, which have largely been neglected in the Vietnamese linguistic literature, are drawn together in this paper in a comparative context with other better-studied languages in order to indicate that Inner Aspect is projected within the VP shell and independently of the projection of Outer Aspect – a structural proposal originally advanced by Travis (2010. Overall, Vietnamese with its isolating character and rigid word order provides us with unusually direct evidence for an articulated VP structure.

Harvey, T.C.

1998-01-01

The establishment of a project to analyse the nature and extent of the problem of marine oil spills and their impact on the wildlife in coastal Newfoundland was described. Pelagic seabirds were identified as the marine wildlife most affected by oil released into the ocean. The Prevention of Oiled Wildlife (POW) project was initiated by the Canadian Coast Guard, the lead agency for oil spills of unknown origin. Details of the POW project were provided. It was shown that the project serves as an interdepartmental approach to: (1) identifying past occurrences, probable sources, causes, effects and possible releases of oil into the marine environment, (2) identifying remedial measures undertaken to date to curb the release of oil, and (3) establishing a plan of action through legislation, education, detection, prosecution or any other means, to eliminate the release of oil. 14 refs., 4 tabs., 5 figs

ENGLISH ABSTRACT: Many projects are not completed on time or within the original budget. This is caused by uncertainty in project variables as well as the occurrence of risk events. A study was done to determine ways of measuring the risk in development projects executed by a mining company in South Africa. The main objective of the study was to determine whether historical project data would provide a more accurate means of estimating the total project duration. Original estimates and actual completion times for tasks of a number of projects were analysed and compared. The results of the study indicated that a more accurate total duration for a project could be obtained by making use of historical project data. The accuracy of estimates could be improved further by building a comprehensive project schedule database within a specific industry.

AFRIKAANSE OPSOMMING: Verskeie projekte word nie binne die oorspronklike skedule of begroting voltooi nie. Dit word dikwels veroorsaak deur onsekerheid oor projekveranderlikes en die voorkoms van risiko’s. 'n Studie is gedoen om 'n metode te ontwikkel om risiko te meet vir ontwikkelingsprojekte van 'n mynmaatskappy in Suid Afrika. Die hoofdoel van die studie was om te bepaal of historiese projekdata gebruik kon word om 'n akkurater tydsduur vir 'n projek te beraam. Die geraamde tydsduur van take vir 'n aantal projekte is ontleed en vergelyk met die werklike tydsduur. Die resultate van die studie het getoon dat 'n akkurater totale tydsduur vir die projek verkry kon word deur gebruik te maak van historiese projekdata. Die akkuraatheid kan verder verbeter word deur 'n databasis van projekskedules vir 'n bepaalde industrie te ontwikkel en by datum te hou.

Functional Echomyography: thickness, ecogenicity, contraction and perfusion of the LMN denervated human muscle before and during h-bFES

Directory of Open Access Journals (Sweden)

Riccardo Zanato

2010-03-01

Full Text Available Permanent denervated muscles were evaluated by ultrasound to monitor changes in morphology, thickness, contraction-relaxation kinetics and perfusion due to the electrical stimulation program of the Rise2-Italy project. In a case of monolateral lesion, morphology and ultrasonographic structure of the denervated muscles changed during the period of stimulation from a pattern typical of complete denervation-induced muscle atrophy to a pattern which might be considered “normal” when detected in an old patient. Thickness improved significantly more in the middle third of the denervated muscle, reaching the same value as the contralateral innervated muscle. Contraction-relaxation kinetics, measured by recording the muscle movements during electrical stimulation, showed an abnormal behavior of the chronically denervated muscle during the relaxation phase, which resulted to be significantly longer than in normal muscle. The long-term denervated muscles analyzed with Echo Doppler showed at rest a low resistance arterial flow that became pulsed during and after electrical stimulation. As expected, the ultra sound measured electrical stimulation-induced hyperemia lasted longer than the stimulation period. The higher than normal energy of the delivered electrical stimuli of the Vienna home-based Functional Electrical Stimulation strategy (h-b FES demonstrate that the explored muscles were still almost completely denervated during the one-year of training. In conclusion, this pilot study confirms the usefulness of Functional Echomyography in the follow-up and the positive effects of h-b FES of denervated muscles.

2016-01-01

Estimating survival in amyotrophic lateral sclerosis (ALS) is challenging due to heterogeneity in clinical features of disease and a lack of suitable markers that predict survival. Our aim was to determine whether scoring of upper or lower motor neuron weakness is associated with survival. With this objective, 161 ALS subjects were recruited from two tertiary referral centres. Scoring of upper (UMN) and lower motor neuron (LMN) signs was performed, in addition to a brief questionnaire. Subjects were then followed until the censorship date. Univariate analysis was performed to identify variables associated with survival to either non-invasive ventilation (NIV) or death, which were then further characterized using Cox regression. Results showed that factors associated with reduced survival included older age, bulbar and respiratory involvement and shorter diagnostic delay (all p NIV or death (p ≤0.001) whereas UMN scores were poorly associated with survival. In conclusion, our results suggest that, early in disease assessment and in the context of other factors (age, bulbar, respiratory status), the burden of LMN weakness provides an accurate estimate of outcome. Such a scoring system could predict prognosis, and thereby aid in selection of patients for clinical trials.

Development of the software dead time methodology for the 4πβ-γ software coincidence system analysis program

International Nuclear Information System (INIS)

Toledo, Fabio de; Brancaccio, Franco; Dias, Mauro da Silva

2009-01-01

The Laboratorio de Metrologia Nuclear - LMN, Nuclear Metrology Laboratory -, at IPEN-CNEN/SP, Sao Paulo, Brazil, developed a new Software Coincidence System (SCS) for 4πβ-γ radioisotope standardization. SCS is composed by the data acquisition hardware, for the coincidence data recording, and the coincidence data analysis program that performs the radioactive activity calculation for the target sample. Due to hardware intrinsic signal sampling characteristics, multiple undesired data recording occurs from a single saturated pulse. Also pulse pileup leads to bad data recording. As the beta counting rates are much greater than the gamma ones, due to the high 4π geometry beta detecting efficiencies, the beta counting significantly increases because of multiple pulse recordings, resulting in a respective increasing in the calculated activity value. In order to minimize such bad recordings effect, a software dead time value was introduced in the coincidence analysis program, under development at LMN, discarding multiple recordings, due to pulse pileup or saturation. This work presents the methodology developed to determine the optimal software dead time data value, for better accuracy results attaining, and discusses the results, pointing to software improvement possibilities.

Albertin, M.; Nichols, R.M.; Edwards, D.T.

1995-01-01

This paper discusses changes made in a demolition project at the Fernald Environmental Management Project (FEMP), a site on the National Priorities list (NPL), owned by the Department of Energy. The project, to demolish fourteen uranium ore silos and their structure, was based on a Removal Action Work Plan, submitted and approved by the United States Environmental Protection Agency (USEPA), that integrated Comprehensive Environmental Response Compensation and Liability Act (CERCLA) requirements to remove the source of contamination and threat to public health and the environment. After the demolition contractor defaulted at 30% complete, completion of the project by the USEPA deadline was threatened. The recovery plan included re-evaluation of project documents in addition to the schedule. It was determined that re-interpretation of the removal action criteria, including design and Removal Action Work Plan, would eliminate road-blocks, and optimize resources, resulting in project completion by the original deadline even after lost-time in mobilizing another contractor. This presentation will discuss the open-quotes lessons learnedclose quotes by the project team and illustrate how simplification of construction methods resulted in enhancements to the environmental controls, improved material handing, and created a safer work environment

Hellsgate Winter Range Mitigation Project; Long-term Management Plan, Project Report 1993, Final Draft.

1994-01-01

A study was conducted on the Hellsgate Winter Range Mitigation Project area, a 4,943 acre ranch purchased for mitigating some habitat losses associated with the original construction of Grand Coulee Dam and innundation of habitat by Lake Roosevelt. A Habitat Evaluation Procedure (HEP) study was used to determine habitat quality and quantity baseline data and future projections. Target species used in the study were sharp-tailed grouse (Tympanuchus phasianellus), mule deer (Odocoileus hemoinus), mink (Mustela vison), spotted sandpiper (Actiius colchicus), bobcat (Felis reufs), blue grouse (Dendragapus obscurus), and mourning dove (Zenaida macroura). From field data collected, limiting life values or HSI's (Habitat Suitability Index's) for each indicator species was determined for existing habitats on project lands. From this data a long term management plan was developed. This report is designed to provide guidance for the management of project lands in relation to the habitat cover types discussed and the indicator species used to evaluate these cover types. In addition, the plan discusses management actions, habitat enhancements, and tools that will be used to enhance, protect and restore habitats to desired conditions. Through planned management actions biodiversity and vegetative structure can be optimized over time to reduce or eliminate, limiting HSI values for selected wildlife on project lands.

Silvennoinen, Kirsi; Heikkilä, Lotta; Katajajuuri, Juha-Matti; Reinikainen, Anu

2015-12-01

We carried out a project to map the volume and composition of food waste in the Finnish food service sector. The amount, type and origin of avoidable food waste were investigated in 51 food service outlets, including schools, day-care centres, workplace canteens, petrol stations, restaurants and diners. Food service outlet personnel kept diaries and weighed the food produced and wasted during a one-week or one-day period. For weighing and sorting, the food waste was divided into two categories: originally edible (OE) food waste was separated from originally inedible (OIE) waste, such as vegetable peelings, bones and coffee grounds. In addition, food waste (OE) was divided into three categories in accordance with its origins: kitchen waste, service waste and customer leftovers. According to the results, about 20% of all food handled and prepared in the sector was wasted. The findings also suggest that the main drivers of wasted food are buffet services and overproduction.

Electronic system for the automation of current measurements produced by ionization chambers

International Nuclear Information System (INIS)

Brancaccio, Franco; Dias, Mauro da Silva

2002-01-01

Ionization Chambers in current mode operation are usually used in Nuclear Metrology in the determination of radionuclide activity. For this purpose measurements of very low ionization currents, in the range of 10 -8 to 10 -14 A, are required. Usually, electrometers perform the current integration method under command of signals from an automation system, in order to reduce the measurement uncertainties. In the present work, an automation system, developed for current integration measurements at the Laboratorio de Metrologia Nuclear (LMN) of Instituto de Pesquisas Energeticas e Nucleares (IPEN), is described. This automation system is composed by software (graphic interface and control) and an electronic module connected to a microcomputer, by means of a commercial data acquisition card CAD12/32 (LYNX Tecnologia Eletronica Ltda.). Measurements, using an electrometer Keithley 616 (Keithley Instruments, Inc) and an ionization chamber IG12/A20 (20 th Century Electronics Ltd.), were performed in order to check the system and for validating the project.

Full Text Available After complete Spinal Cord Injury (SCI, causing complete disconnection between the muscle fibers and the nervous system, the denervated muscles become unexcitable with commercial electrical stimulators within several months and undergo severe atrophy and disorganization of contractile apparatus after 1-3 years. Years after the injury the surviving and regenerated myofibers are substituted with adipocytes and collagen. To counteract the progressive changes transforming muscle into an unexcitable tissue, we developed a novel therapy concept for paraplegic patients with complete lower motor neuron (LMN denervation of the lower extremities. The new stimulators for home-based functional electrical stimulation (h-b FES have been designed to reverse longstanding and severe atrophy of LMN denervated muscles by delivering high-intensity (up to 2,4 J and long-duration impulses (up to 150 ms able to elicit contractions of denervated skeletal muscle fibers in absence of nerve. Concurrent to the development of the stimulation equipment, specific clinical assessments and training strategies were developed at the Wilhelminenspital Wien, Austria. Main results of our clinical study on 20 patients, which completed a 2 years h-b FES program are: 1. significant +33% increase of muscle size and +75% of the mean diameter of muscle fibers, with striking improvements of the ultra-structural organization of contractile material; 2. recovery of the tetanic contractility with significant increase in muscle force output during electrical stimulation; 3. five subjects performed FES-assisted stand-up and stepping-in-place exercises;. 4. data from ultrastructural analyses indicating that the shorter the time span between SCI and the beginning of h-b FES, the larger were the number and the size of recovered fibers. The study demonstrates that h-b FES of permanent LMN denervated muscle is an effective home therapy that results in rescue of muscle mass, function and perfusion

Power project financing in the People's Republic of China

The current state of financing and security issues which in the past have constrained the amount of foreign investment and project financing in the electric power market in the Peoples Republic of China (PRC) are reviewed. Past impediments to foreign investment and financing of power projects revolved around the rate of return on investment, the difficulties of obtaining project approvals, conflict of interest issues wherein the Chinese power bureau could act in its interest as a contracted party rather than for the joint venture as an equity investor, and currency convertibility. Recent developments such as the new security law, the new electricity law, and new project financing regulations represent major improvements, but foreign investment and financing is still much less than originally anticipated, the potential of the PRC power market for foreign investments notwithstanding. (For example, in 1997, 13,500 MW of new generation capacity was added to the Chinese grid system. This increased the total installed capacity to 250,000 MW, making China the second largest installed capacity in the world.) Recent trends in the market and the likely future of foreign investment in the PRC are also discussed, the conclusion being that although the size of the IPP and project finance market in China is probably smaller than originally hoped, a sufficient proportion of new generation capacity has been allocated to foreign investors to ensure a steady stream of investment opportunities

2007-12-01

Developed to allow high school students with special needs to participate in original scientific research, the Peer Mentoring Program was a supplement to existing science instruction for students in a self-contained classroom. Peer mentors were high school seniors at the end of a three-year advanced science research course who used their experience to create and develop inquiry-based research activities appropriate for students in the self- contained classroom. Peer mentors then assisted cooperative learning groups of special education students to facilitate the implementation of the research activities. Students with special needs successfully carried out an original research project and developed critical thinking and laboratory skills. Prior to embarking on their undergraduate course of study in the sciences, peer mentors developed an appreciation for the need to bring original scientific research to students of all levels. The program will be expanded and continued during the 2007-2008 school year.

Metrology of ionizing radiation started soon after the discovery of radioactivity. However, the modern metrology of ionizing radiation can be considered a by product of the Manhattan Project. When this mammoth effort to produce the first nuclear weapons was initiated, little was known about some of the properties of natural elements, though the phenomenon of natural radioactivity was already known for almost half a century. Less was known about the radioactive materials involved in that project. The amount of those materials which had to be handled were higher than any amount of {sup 226} Ra and {sup 228} Ra ever used thus far. The first atomic piles produced concentration levels of radioactivity much higher than any level known before. There was then a threat not only for the health of hundred of technicians and scientists, but also for thousands of workers. The secrecy involving that project would not allow much to be told about the radioactive hazards. There was, however, the need to protect workers and the public in General against unnecessary exposures to ionizing radiation. The origin of the standards used in radiological protection from pre-world war II and their remarkable evolution during and immediately after this war will be discussed in the paper. (author)

Team work on international projects

International Nuclear Information System (INIS)

Hayfield, F.

1983-01-01

A successful team will result in Project efficiency and so lead to a better achievement of the Project objectives. Such a team will be self-motivating and have a high level of morale. An effective team will also create a better context for transfer of know-how and so better prepare its members for greater roles on future Project teams. The nature of Project work forces the process of team building to recognize several facts of life. A Project team can have a life as short as one year and as long as ten years. A team usually consists of people on temporary transfer from different departments yet retaining a link of some sort to their departments of origin. It may consist of members of one company only or of several as in a joint-venture and may include Client personnel. On International Projects, the members of a team may have different nationalities and be working in a language foreign to many of them. Many of the Project people may be expatriates to the Project area on a bachelor or on a married status well away from their head or usual office. Team building is a complex organizational and human process, with no mathematical formula for the ideal solution. It starts with the selection of the right Project Manager who should be a leader, a technocrat manager and an integrator all at the same time. The Project Manager must have the authority to create the organizational and human climate that will motivate to a maximum each member of the team. Each member must understand clearly his role and realize that this contribution to the Project will influence his career development. Loyalty to the Project Manager must be possible and the Departmental Manager has to recognize this necessity. This presentation will indicate the basic steps of a team building process on a typical major international Project

Ceramic Technology Project, semiannual progress report for October 1993 through March 1994

Johnson, D.R.

1994-09-01

The Ceramic Technology Project was originally developed by the Department of Energy`s Office of Transportation Systems (OTS) in Conservation and Renewable Energy. Significant accomplishments in fabricating ceramic components for the Department of Energy (DOE), National Aeronautics and Space Administration (NASA), and Department of Defense (DoD) advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. An assessment of needs was completed, and a five-year project plan was developed with extensive input from private industry. In July 1990, the original plan was updated through the estimated completion of development in 1993. The original objective of the project was to develop the industrial technology base required for reliable ceramics for application in advanced automotive heat engines. During the course of the Ceramic Technology Project, remarkable progress has been made in the development of reliable structural ceramics. The direction of the Ceramic Technology Project is now shifting toward reducing the cost of ceramics to facilitate commercial introduction of ceramic components for near-term engine applications. In response to extensive input from industry, the plan is to extend the engine types which were previously supported (advanced gas turbine and low-heat-rejection diesel engines) to include near-term (5-10 years) applications in conventional automobile and diesel truck engines. To facilitate the rapid transfer of this technology to U.S. industry, the major portion of the work is being done in the ceramic industry, with technological support from government laboratories, other industrial laboratories, and universities. A systematic approach to reducing the cost of components is envisioned.

The Ceramic Technology Project was developed by the USDOE Office of Transportation Systems (OTS) in Conservation and Renewable Energy. This project, part of the OTS's Materials Development Program, was developed to meet the ceramic technology requirements of the OTS's automotive technology programs. Significant accomplishments in fabricating ceramic components for the USDOE and NASA advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. These programs have also demonstrated that additional research is needed in materials and processing development, design methodology, and data base and life prediction before industry will have a sufficient technology base from which to produce reliable cost-effective ceramic engine components commercially. A five-year project plan was developed with extensive input from private industry. In July 1990 the original plan was updated through the estimated completion of development in 1993. The objective is to develop the industrial technology base required for reliable ceramics for application in advanced automotive heat engines. The project approach includes determining the mechanisms controlling reliability, improving processes for fabricating existing ceramics, developing new materials with increased reliability, and testing these materials in simulated engine environments to confirm reliability. Although this is a generic materials project, the focus is on the structural ceramics for advanced gas turbine and diesel engines, ceramic bearings and attachments, and ceramic coatings for thermal barrier and wear applications in these engines. To facilitate the rapid transfer of this technology to US industry, the major portion of the work is being done in the ceramic industry, with technological support from government laboratories, other industrial laboratories, and universities.

The main goal of post genomics is to explain how the genome, the map of which has been constructed in the Human Genome Project, affacts activities of life. This leads to generate multiple "omics": structural genomics, functional genomics, proteomics, metabonomics, et al. In Jun. 2006, Melbourne, Australia, Human Genome Variation Society (HGVS) initiated the Human Variome Project (HVP) to collect all the sequence variation and polymorphism data worldwidely. HVP is to search and determine those mutations related with human diseases by association study between genetype and phenotype on the scale of genome level and other methods. Those results will be translated into clinical application. Considering the potential effects of this project on human health, this paper introduced its origin and main content in detail and discussed its meaning and prospect.

The origin of the logic of symbolic mathematics Edmund Husserl and Jacob Klein

2011-01-01

Burt C. Hopkins presents the first in-depth study of the work of Edmund Husserl and Jacob Klein on the philosophical foundations of the logic of modern symbolic mathematics. Accounts of the philosophical origins of formalized concepts-especially mathematical concepts and the process of mathematical abstraction that generates them-have been paramount to the development of phenomenology. Both Husserl and Klein independently concluded that it is impossible to separate the historical origin of the thought that generates the basic concepts of mathematics from their philosophical meanings. Hopkins explores how Husserl and Klein arrived at their conclusion and its philosophical implications for the modern project of formalizing all knowledge.

Full Text Available This essay tightens the “origin” concept, its manifestation through puzzles and their relationship to techniques of reproduction. Contrary to the hegemonic critique of aesthetic and cultural objects – critique that, settled on the appearance and notions of identity, tradition, canon, etc., undervalues the reproductions of "originals" –, the aim is to deliver these objects from formal hierarchization dispositives, that is, release them of what is ideal and positively imposed, so that the reproducibility is potentiated as producer of singularities, of apparitions. The effort is to keep the undecided character of puzzles (bodies, texts, images in which the origin is manifest, so that the logic of the spectacle is reverted into sense opening, instance in which the aesthetic becomes a “performance” before contemporary complexity. With the reproducibility, an origin survives in passage: continually restored, but incomplete, present in trace, in absence.

The overall objective of this project was to use extensive Gypsy Field Laboratory and data as a focus for developing and testing reservoir characterization methods that are targeted at improved recovery of conventional oil. This report describes progress since project report DOE/BC/14970-7 and covers the period June 1997-September 1998 and represents one year of funding originally allocated for the year 1996. During the course of the work previously performed, high resolution geophysical and outcrop data revealed the importance of fractures at the Gypsy site. In addition, personnel changes and alternative funding (OCAST and oil company support of various kinds) allowed the authors to leverage DOE contributions and focus more on geophysical characterization.

Brayton Point coal conversion project (NEPCO)

The New England Power Company (NEPCO) recently converted Brayton Point Power Station Units 1, 2, and 3 from oil to coal. The coal conversion project is the largest coal conversion project in the nation to date. Stone and Webster Engineering Corporation (SWEC) was hired as the engineer/constructor for the project. Units 1 and 2 are 250-MW Combustion Engineering boilers, and Unit 3 is a 650-MW Babcock and Wilcox boiler. All three units were originally designed to burn pulverized coal but were converted to oil during the years of low oil prices. Studies performed by NEPCO and SWEC indicated that the areas discussed in the following paragraphs required upgrading before the units could efficiently burn coal and meet Federal and State environmental requirements. All units have been converted and are operating. This paper discusses design modifications required to burn coal, startup, and initial operating problems, and solutions.

The rare-earth crisis, which peaked in the summer of 2011 with the prices of both light and heavy rare earths soaring to unprecedented levels, brought about the widespread realization that the long-term availability and price stability of rare earths could not be guaranteed. This triggered a rapid response from manufacturers involved in rare earths, as well as governments and national and international funding agencies. In the case of rare-earth-containing permanent magnets, three possibilities were given quick and serious consideration: (I) increased recycling of devices containing rare earths; (II) the search for new, mineable, rare-earth resources beyond those in China; and (III) the development of high-energy-product permanent magnets with little or no rare-earth content used in their manufacture. The Replacement and Original Magnet Engineering Options (ROMEO) project addresses the latter challenge using a two-pronged approach. With its basis on work packages that include materials modeling and advanced characterization, the ROMEO project is an attempt to develop a new class of novel permanent magnets that are free of rare earths. Furthermore, the project aims to minimize rare-earth content, particularly heavy-rare-earth (HRE) content, as much as possible in Nd-Fe-B-type magnets. Success has been achieved on both fronts. In terms of new, rare-earth-free magnets, a Heusler alloy database of 236,945 compounds has been narrowed down to approximately 20 new compounds. Of these compounds, Co2MnTi is expected to be a ferromagnet with a high Curie temperature and a high magnetic moment. Regarding the reduction in the amount of rare earths, and more specifically HREs, major progress is seen in electrophoretic deposition as a method for accurately positioning the HRE on the surface prior to its diffusion into the microstructure. This locally increases the coercivity of the rather small Nd-Fe-B-type magnet, thereby substantially reducing the dependence on the HREs Dy and

2002-01-01

The National Transuranic (TRU) Program (NTP) is being optimized to allow for disposing of the legacy TRU waste at least 10 years earlier than originally planned. This acceleration will save the nation an estimated $713. The Department of Energy's (DOE'S) Carlsbad Field Office (CBFO) has initiated the National TRU Waste System Optimization Project to propose, and upon approvaI, implement activities that produce significant cost saving by improving efficiency, thereby accelerating the rate of TRU waste disposal without compromising safety. In its role as NTP agent of change, the National TRU Waste System Optimization Project (the Project) (1) interacts closely with all NTP activities. Three of the major components of the Project are the Central Characterization Project (CCP), the Central Confirmation Facility (CCF), and the MobiIe/Modular Deployment Program.

It is recommended to create a structure of project work starting from the analytical research existing at the enterprise or recommended by standards and guidelines on project management approaches to building a hierarchical structure of works, templates of project work structures. It is noted that the created structure of project work should be audited by participants of the project office. According to the results of planning the sequence and duration of operations for managing the scope of works, a precedence diagram of the investigated process is constructed. Value/originality. The developed recommendations regarding the consistency and structure of subprocesses and operations of the project scope management will allow the enterprise to significantly save time for planning the scope of subsequent projects, using the database created in previous periods, statistics on the implementation of the described operations.

Estimating the greenhouse gas benefits of forestry projects: A Costa Rican Case Study

Energy Technology Data Exchange (ETDEWEB)

Busch, Christopher; Sathaye, Jayant; Sanchez Azofeifa, G. Arturo

2000-09-01

If the Clean Development Mechanism proposed under the Kyoto Protocol is to serve as an effective means for combating global climate change, it will depend upon reliable estimates of greenhouse gas benefits. This paper sketches the theoretical basis for estimating the greenhouse gas benefits of forestry projects and suggests lessons learned based on a case study of Costa Rica's Protected Areas Project, which is a 500,000 hectare effort to reduce deforestation and enhance reforestation. The Protected Areas Project in many senses advances the state of the art for Clean Development Mechanism-type forestry projects, as does the third-party verification work of SGS International Certification Services on the project. Nonetheless, sensitivity analysis shows that carbon benefit estimates for the project vary widely based on the imputed deforestation rate in the baseline scenario, e.g. the deforestation rate expected if the project were not implemented. This, along with a newly available national dataset that confirms other research showing a slower rate of deforestation in Costa Rica, suggests that the use of the 1979--1992 forest cover data originally as the basis for estimating carbon savings should be reconsidered. When the newly available data is substituted, carbon savings amount to 8.9 Mt (million tones) of carbon, down from the original estimate of 15.7 Mt. The primary general conclusion is that project developers should give more attention to the forecasting land use and land cover change scenarios underlying estimates of greenhouse gas benefits.

Searching for the origin of masses

International Nuclear Information System (INIS)

Iwasaki, Hiroyuki

2002-01-01

The origin of masses of weak gauge bosons as well as quarks and leptons is one of the most mysterious themes in high energy physics. In the standard model, it is explained as a result of a spontaneous symmetry breaking of the vacuum, which is caused by self-interaction of an unknown complex scalar field. Three weak gauge bosons acquire their masses by 'eating' the three components of the scalar field. The remaining one component survives and called the 'Higgs boson'. Masses of quarks and leptons are generated by an interaction between those particles and the scalar field. Searching for the Higgs boson is a key step toward deeper understanding of nature. In the lecture, a brief introduction of theoretical aspects and an experimental approach based on an ongoing project will be given

The projective heat map

CERN Document Server

Schwartz, Richard Evan

2017-01-01

This book introduces a simple dynamical model for a planar heat map that is invariant under projective transformations. The map is defined by iterating a polygon map, where one starts with a finite planar N-gon and produces a new N-gon by a prescribed geometric construction. One of the appeals of the topic of this book is the simplicity of the construction that yet leads to deep and far reaching mathematics. To construct the projective heat map, the author modifies the classical affine invariant midpoint map, which takes a polygon to a new polygon whose vertices are the midpoints of the original. The author provides useful background which makes this book accessible to a beginning graduate student or advanced undergraduate as well as researchers approaching this subject from other fields of specialty. The book includes many illustrations, and there is also a companion computer program.

What drives continuous improvement project success in healthcare?

Stelson, Paul; Hille, Joshua; Eseonu, Chinweike; Doolen, Toni

2017-02-13

Purpose The purpose of this paper is to present findings from a study of factors that affect continuous improvement (CI) project success in hospitals. Design/methodology/approach Quantitative regression analysis was performed on Likert scale survey responses. Qualitative thematic analysis was performed on open-ended survey responses and written reports on CI projects. Findings The paper identifies managerial and employee factors that affect project success. These factors include managerial support, communication, and affective commitment. Affective commitment is the extent to which employees perceive the change as being needed or necessary. Practical implications The results highlight how managerial decisions, approaches to communication - including communication before, during and after CI projects affect project success. The results also show that success depends on the way employees perceive proposed changes. This suggests the need for a more individualized approach to CI, lean, and broader change initiatives. Originality/value This research is the first to fuse project success and sustainability theory to CI projects, beyond Kaizen events, in healthcare environments. The research is particularly important at a time when healthcare organizations are required to make rapid changes with limited resources as they work toward outcome-based assessment and reimbursement rules.

Little is understood about how ownership shifts from academic to community partners. . We examined a CBPR project over its life course and asked: what does the evolution of ownership look like from project initiation by an academic (non-community) champion (T1); to maturation-when the intervention is ready to be deployed (T2); to independence-the time when the original champion steps aside (T3); and finally, to its maintenance-when the community has had an opportunity to function independently of the original academic champion (T4)? . Using sociometric (whole network) social network analysis, knowledge leadership was measured using 'in-degree centrality'. Stakeholder network structure was measured using 'centralisation' and 'core-periphery analysis'. Friedman rank sum test was used to measure change in actor roles over time from T1 to T4. . Project stakeholder roles were observed to shift significantly (P project maintenance (T4). Community stakeholders emerged into positions of knowledge leadership, while the roles of academic partners diminished in importance. The overall stakeholder network demonstrated a structural shift towards a core of densely interacting community stakeholders. . This was the first study to use Social network analysis to document a shift in ownership from academic to community partners, indicating community self-determination over the research process. Further analysis of qualitative data will determine which participatory actions or strategies were responsible for this observed change. © The Author 2017. Published by Oxford University Press.

A first document proposes graphs, figures and maps which illustrate various aspects of the situation and development of methanization in France and in the Burgundy-Franche-Comte region (number and location of installations, production evolution, biomass origins, biogas valorisation). A second document presents methanization (basic principles, process types, valorisation), describes agricultural methanization (substrate origin, use of final energy, use of digestates) and proposes elements of thought for methanization development regarding waste origin, project definition, various concerns (energy, environment, agriculture), digestate use and quantities, methane use, and installation sizing. A publication then proposes a synthetic overview of methanization development in Burgundy: number of supported projects, installations (evolution of their number, used materials, production), and support activities. The next publication proposes an assessment and an overview of the biogas sector in Burgundy: presentation and recommendations, assessment in terms of jobs, activities and expertise, professional education and training. The last document recalls some elements related to the methanization technique, outlines some important issues (materials, valorisation type for biogas and for digestate) to be addressed for an agricultural methanization project, and evokes benefits of methanization and some economic aspects. It also briefly describes how to start a project in the region

EUDP Project: Low Noise Airfoil - Final Report

DEFF Research Database (Denmark)

This document summarizes the scientific results achieved during the EUDP-funded project `Low-Noise Airfoil'. The goals of this project are, on one side to develop a measurement technique that permits the evaluation of trailing edge noise in a classical aerodynamic wind tunnel, and on the other side...... to develop and implement a design procedure to manufacture airfoil profiles with low noise emission. The project involved two experimental campaigns: one in the LM Wind Power wind tunnel, a classical aerodynamic wind tunnel, in Lunderskov (DK), the second one in the Virginia Tech Stability Wind Tunnel....... In particular, the so-called TNO trailing edge noise model could be significantly improved by introducing turbulence anisotropy in its formulation, as well as the influence of the boundary layer mean pressure gradient. This two characteristics are inherent to airfoil flows but were neglected in the original...

First Industrial Tests of a Matrix Monitor Correction for the Differential Die-away Technique of Historical Waste Drums

2015-01-01

The fissile mass in radioactive waste drums filled with compacted metallic residues (spent fuel hulls and nozzles) produced at AREVA NC La Hague reprocessing plant is measured by neutron interrogation with the Differential Die-away measurement Technique (DDT). In the next years, old hulls and nozzles mixed with Ion-Exchange Resins will be measured. The ion-exchange resins increase neutron moderation in the matrix, compared to the waste measured in the current process. In this context, the Nuclear Measurement Laboratory (LMN) of CEA Cadarache has studied a matrix effect correction method, based on a drum monitor, namely a 3He proportional counter located inside the measurement cavity. After feasibility studies performed with LMN's PROMETHEE 6 laboratory measurement cell and with MCNPX simulations, this paper presents first experimental tests performed on the industrial ACC (hulls and nozzles compaction facility) measurement system. A calculation vs. experiment benchmark has been carried out by performing dedicated calibration measurements with a representative drum and 235 U samples. The comparison between calculation and experiment shows a satisfactory agreement for the drum monitor. The final objective of this work is to confirm the reliability of the modeling approach and the industrial feasibility of the method, which will be implemented on the industrial station for the measurement of historical wastes.

Conformal invariance of the Lungren-Monin-Novikov equations for vorticity fields in 2D turbulence

Science.gov (United States)

Grebenev, V. N.; Wacławczyk, M.; Oberlack, M.

2017-10-01

We study the statistical properties of the vorticity field in two-dimensional turbulence. The field is described in terms of the infinite Lundgren-Monin-Novikov (LMN) chain of equations for multi-point probability density functions (pdf’s) of vorticity. We perform a Lie group analysis of the first equation in this chain using the direct method based on the canonical Lie-Bäcklund transformations devised for integro-differential equations. We analytically show that the conformal group is broken for the first LMN equation i.e. for the 1-point pdf at least for the inviscid case but the equation is still conformally invariant on the associated characteristic with zero-vorticity. Then, we demonstrate that this characteristic is conformally transformed. We find this outcome coincides with the numerical results about the conformal invariance of the statistics of zero-vorticity isolines, see e.g. Falkovich (2007 Russian Math. Surv. 63 497-510). The conformal symmetry can be understood as a ‘local scaling’ and its traces in two-dimensional turbulence were already discussed in the literature, i.e. it was conjectured more than twenty years ago in Polyakov (1993 Nucl. Phys. B 396 367-85) and clearly validated experimentally in Bernard et al (2006 Nat. Phys. 2 124-8).

Final Technical Report. Origins of subsurface microorganisms: Relating laboratory microcosm studies to a geologic time scale; FINAL

International Nuclear Information System (INIS)

Kieft, Thomas; Amy, Penny S.; Phillips, Fred M.

1998-01-01

This project was conducted as part of the Department of Energy's Deep Subsurface Science Program. It was part of a larger effort to determine the origins of subsurface microorganisms. Two hypotheses have been suggested for the origins of subsurface microorganisms: (1) microorganisms were deposited at the time of (or shortly after) geologic deposition of rocks and sediments (the in situ survival hypothesis), and (2) microorganisms have been transported from surface environments to subsurface rocks and sediments since the time of geologic deposition (transport hypothesis). These two hypotheses are not mutually exclusive. Depending on the geological setting, either one or both of these hypotheses may best explain microbial origins. Our project focused on the in situ survival hypothesis. We tested the hypothesis that microorganisms (individuals populations and communities) can survive long-term sequestration within subsurface sediments. Other objectives were to identify geologic conditions that favor long-term survival, identify physiological traits of microorganisms that favor long-term survival, and determine which groups of microorganisms are most likely to survive long-term sequestration in subsurface sediments. We tested this hypothesis using a combination of pure culture techniques in laboratory microcosms under controlled conditions and field experiments with buried subsurface sediments

Reactor-specific spent fuel discharge projections, 1984 to 2020

International Nuclear Information System (INIS)

Heeb, C.M.; Libby, R.A.; Holter, G.M.

1985-04-01

The original spent fuel utility data base (SFDB) has been adjusted to produce agreement with the EIA nuclear energy generation forecast. The procedure developed allows the detail of the utility data base to remain intact, while the overall nuclear generation is changed to match any uniform nuclear generation forecast. This procedure adjusts the weight of the reactor discharges as reported on the SFDB and makes a minimal (less than 10%) change in the original discharge exposures in order to preserve discharges of an integral number of fuel assemblies. The procedure used in developing the reactor-specific spent fuel discharge projections, as well as the resulting data bases themselves, are described in detail in this report. Discussions of the procedure cover the following topics: a description of the data base; data base adjustment procedures; addition of generic power reactors; and accuracy of the data base adjustments. Reactor-specific discharge and storage requirements are presented. Annual and cumulative discharge projections are provided. Annual and cumulative requirements for additional storage are shown for the maximum at-reactor (AR) storage assumption, and for the maximum AR with transshipment assumption. These compare directly to the storage requirements from the utility-supplied data, as reported in the Spent Fuel Storage Requirements Report. The results presented in this report include: the disaggregated spent fuel discharge projections; and disaggregated projections of requirements for additional spent fuel storage capacity prior to 1998. Descriptions of the methodology and the results are included in this report. Details supporting the discussions in the main body of the report, including descriptions of the capacity and fuel discharge projections, are included. 3 refs., 6 figs., 12 tabs

Full Text Available In the stages of understanding and study, by students, of descriptive geometry, the treble orthogonal projection of a point, creates problems in the situations in that one or more descriptive coordinates are zero. Starting from these considerations the authors have created an original computer program which offers to the students the possibility to easily understanding of the way in which a point is represented, in draught, in the treble orthogonal projection whatever which are its values of the descriptive coordinates.

PROJECT ACTIVITY ANALYSIS WITHOUT THE NETWORK MODEL

Directory of Open Access Journals (Sweden)

Full Text Available

ENGLISH ABSTRACT: This paper presents a new procedure for analysing and managing activity sequences in projects. The new procedure determines critical activities, critical path, start times, free floats, crash limits, and other useful information without the use of the network model. Even though network models have been successfully used in project management so far, there are weaknesses associated with the use. A network is not easy to generate, and dummies that are usually associated with it make the network diagram complex – and dummy activities have no meaning in the original project management problem. The network model for projects can be avoided while still obtaining all the useful information that is required for project management. What are required are the activities, their accurate durations, and their predecessors.

Simon P Philbin

2014-10-01

Full Text Available Purpose: Development of a practitioner oriented diagnostic framework and health check tool to support the robust assessment of engineering and technology projects.Design/methodology/approach: The research is based on a literature review that draws together insights on project assessment and critical success factors to establish an integrated systems view of projects. This is extended to allow a comprehensive diagnostic framework to be developed along with a high-level health check tool that can be readily deployed on projects. The utility of the diagnostic framework and health check tool are explored through three illustrative case studies, with two from Canada and one from the United Kingdom. Findings andOriginality/value: The performance of engineering and technology projects can be viewed through a systems perspective and being a function of six sub-systems that are: process, technology, resources, impact, knowledge and culture. The diagnostic framework that is developed through this research integrates these sub-systems to provide a comprehensive assessment methodology for projects, which is linked to existing best practice for project reviews, performance management and maturity models. The case studies provide managerial insights that are related to the diagnostic framework but crucially also position the approach in the context of industrial applications for construction engineering and technology management.Research limitations/implications: The case study approach includes two case studies from the construction and facilities development sector with the third case study from the research and technology sector. Further work is required to investigate the use of the diagnostic framework and health check tool in other sectors.Practical implications: The health check tool will be of practical benefit to new projects managers that require access to a robust and convenient project review methodology for assessing the status and health of a

Project to expand diversity in the nursing workforce.

Georges, Catherine

2012-05-01

The Bronx, one of the five boroughs of New York City, has a diverse population, but the largest ethnic group is Hispanic, or Latino. More than half (53 per cent) of the students at Lehman College of the City University of New York are from this group, reflecting the population demographic of the borough, but in 2006 Hispanic students comprised just 8 per cent of those enrolled in the department of nursing. To address this disparity, the department undertook a project to increase recruitment, retention and graduation of Hispanic nursing students. The project involved several activities in collaboration with a Bronx high school, Lehman College's baccalaureate nursing programme, and a partner hospital that serves thousands of people of Hispanic origin. This article describes the project and the lessons learnt.

The Los Alamos Neutron Science Center (LANSCE) accelerator is an 800-MeV proton linac that drives user facilities for isotope production, proton radiography, ultra-cold neutrons, weapons neutron research and various sciences using neutron scattering. The LANSCE Refurbishment Project (LANSCE-R) is an ambitious project to refurbish key elements of the LANSCE accelerator that are becoming obsolete or nearing end-of-life. The conceptual design phase for the project is funded and underway. The 5 year, $170M (US) project will enable future decades of reliable, high-performance operation. It will replace a substantial fraction of the radio-frequency power systems (gridded tubes and klystrons) with modern systems, completely refurbish the original accelerator control and timing systems, replace obsolete diagnostic devices, and modernize other ancillary systems. An overview of the LANSCE-R project will be presented. The functional and operating requirements will be discussed, the proposed technical solutions presented, and the plan for successful project execution while meeting annual customer expectations for beam delivery will be reviewed.

City of Austin: Green habitat learning project. A green builder model home project

1995-12-01

The purpose of the Year 14 UCETF project was to design and construct a residential structure that could serve as a demonstration facility, training site, and testing and monitoring laboratory for issues related to the implementation of sustainable building practices and materials. The Model Home Project builds on the previous and existing efforts, partially funded by the UCETF, of the City of Austin Green Builder Program to incorporate sustainable building practices into mainstream building activities. The Green Builder Program uses the term {open_quotes}green{close_quotes} as a synonym for sustainability. In the research and analysis that was completed for our earlier reports in Years 12 and 13, we characterized specific elements that we associate with sustainability and, thus, green building. In general, we refer to a modified life cycle assessment to ascertain if {open_quotes}green{close_quotes} building options reflect similar positive cyclical patterns found in nature (i.e. recyclability, recycled content, renewable resources, etc.). We additionally consider economic, human health and synergistic ecological impacts associated with our building choices and characterize the best choices as {open_quotes}green.{close_quotes} Our ultimate goal is to identify and use those {open_quotes}green{close_quotes} materials and processes that provide well for us now and do not compromise similar benefits for future generations. The original partnership developed for this project shifted during the year from a project stressing advanced (many prototypical) {open_quotes}green{close_quotes} building materials and techniques in a research and demonstration context, to off-the-shelf but underutilized {open_quotes}green{close_quotes} materials in the practical social context of using {open_quotes}green{close_quotes} technologies for low income housing. That project, discussed in this report, is called the Green Habitat Learning Project.

Mrica Hydroelectric Project: a study in partnering

International Nuclear Information System (INIS)

Loraine, R.K.; Bannmark, O.

1993-01-01

This paper describes the contractual and financial aspects of the Mrica Project. Of particular interest is the high degree of cooperation that developed between the various parties, and the effect this had on the progress and completion of the project. This relationship had its origin in the need to make the best use of the relatively scarce funds available. It was vitally important that problems were solved jointly and that costs did not escalate as a result of confrontation between the parties. In this respect, the project was an early manifestation of the contractual relationship now called partnering, and the procedures adopted at Mrica are very similar to those now widely used in partnering contracts. The paper is therefore structured to identify and analyse the key elements of co-operation, and their impact on both the negotiation of the contracts and the completion of the works. (Author)

2010-01-01

Objective: To discuss the clinical significance of anomalous origination of right gastric artery in interventional treatment for hepatocellular carcinoma (HCC). Methods: The dynamic enhanced CT scanning of the liver with a 64-slice spiral CT unit was performed in 72 HCC patients. In arterial phase, maximum intensity projection (MIP) and volume reconstruction technique (VRT) were used to observe the origin of the right gastric artery and its relationship with the hepatic artery. The findings were compared with the angiographic results. Results: Of the total 72 cases, the anomalous origin of the right gastric artery was found in 43 (59.8%). The anomalous origins of the right gastric artery included proper hepatic artery (n=19), left hepatic artery (n=17), gastroduodenal artery (n=4), right hepatic artery (n=2) and common hepatic artery (n=1). The results obtained from three-dimensional reconstruction were in good accordance with angiographic findings. Conclusion: The anomalously originated right gastric artery most commonly originates from the left hepatic artery. Three-dimensional reconstruction obtained from the 64-slice spiral CT scans can provide the clear and reliable images of the right gastric artery, which is very helpful for the interventional procedure.

1985-01-01

Some of the main, general-perspective themes of Dr. Alvin Weinberg's leadership and long and varied work are: the effect of present and future nuclear energy projects on society, not only in the United States but throughout the world; analysis, comparison, and combination of various sources of energy; extensive multiple use of nuclear energy complexes (so-called NUPLEX, for nuclear complex) for various areas of the world; and use of ''Big Technology'' and ''Big Science'' for solving, or helping to solve, political problems. A combined hydro-nuclear-solar project for electric power production is discussed, as well as two other energy-related engineering projects. Some of the projects originated or were inspired by work done at the Oak Ridge National Laboratory under the leadership of Dr. Alvin Weinberg. Also reported are the technical characteristics and interrelationships of the three components of the envisaged hydronuclear-solar project

The Sterling experiment, detonated Dec. 3, 1966, was the first decoupled underground nuclear detonation. This experiment used the existing Salmon cavity and the original Salmon emplacement hole. The principal purpose of the Sterling experiment was (1) to determine the extent of decoupling of a sprung cavity in salt; specifically, to determine the decoupling ratio as a function of frequency; (2) to determine the accuracy of decoupling calculations for a sprung cavity; and (3) to define any operational problems associated with the reuse of a cavity. Project Sterling is a part of the Vela Uniform program. Vela is the short title of a research and development program directed toward locating, detecting, and identifying underground, surface, and high altitude nuclear detonations. The administration, operational planning, public safety, engineering and construction and logistics performed by NVOO in support of the technical and scientific experiments carried out are presented.

Saccone, Scott F; Quan, Jiaxi; Jones, Peter L

2012-04-15

Public genomic databases, which are often used to guide genetic studies of human disease, are now being applied to genomic medicine through in silico integrative genomics. These databases, however, often lack tools for systematically determining the experimental origins of the data. We introduce a new data provenance model that we have implemented in a public web application, BioQ, for assessing the reliability of the data by systematically tracing its experimental origins to the original subjects and biologics. BioQ allows investigators to both visualize data provenance as well as explore individual elements of experimental process flow using precise tools for detailed data exploration and documentation. It includes a number of human genetic variation databases such as the HapMap and 1000 Genomes projects. BioQ is freely available to the public at http://bioq.saclab.net.

DESIGN VERIFICATION REPORT SPENT NUCLEAR FUEL (SNF) PROJECT CANISTER STORAGE BUILDING (CSB)

International Nuclear Information System (INIS)

BAZINET, G.D.

2003-01-01

The Sub-project W379, ''Spent Nuclear Fuel Canister Storage Building (CSB),'' was established as part of the Spent Nuclear Fuel (SNF) Project. The primary mission of the CSB is to safely store spent nuclear fuel removed from the K Basins in dry storage until such time that it can be transferred to the national geological repository at Yucca Mountain Nevada. This sub-project was initiated in late 1994 by a series of studies and conceptual designs. These studies determined that the partially constructed storage building, originally built as part of the Hanford Waste Vitrification Plant (HWVP) Project, could be redesigned to safely store the spent nuclear fuel. The scope of the CSB facility initially included a receiving station, a hot conditioning system, a storage vault, and a Multi-Canister Overpack (MCO) Handling Machine (MHM). Because of evolution of the project technical strategy, the hot conditioning system was deleted from the scope and MCO welding and sampling stations were added in its place. This report outlines the methods, procedures, and outputs developed by Project W379 to verify that the provided Structures, Systems, and Components (SSCs): satisfy the design requirements and acceptance criteria; perform their intended function; ensure that failure modes and hazards have been addressed in the design; and ensure that the SSCs as installed will not adversely impact other SSCs. The original version of this document was prepared by Vista Engineering for the SNF Project. Revision 1 documented verification actions that were pending at the time the initial report was prepared. Revision 3 of this document incorporates MCO Cover Cap Assembly welding verification activities. Verification activities for the installed and operational SSCs have been completed

Quasi Gradient Projection Algorithm for Sparse Reconstruction in Compressed Sensing

Directory of Open Access Journals (Sweden)

Xin Meng

2014-02-01

Full Text Available Compressed sensing is a novel signal sampling theory under the condition that the signal is sparse or compressible. The existing recovery algorithms based on the gradient projection can either need prior knowledge or recovery the signal poorly. In this paper, a new algorithm based on gradient projection is proposed, which is referred as Quasi Gradient Projection. The algorithm presented quasi gradient direction and two step sizes schemes along this direction. The algorithm doesn’t need any prior knowledge of the original signal. Simulation results demonstrate that the presented algorithm cans recovery the signal more correctly than GPSR which also don’t need prior knowledge. Meanwhile, the algorithm has a lower computation complexity.

Aufklärung and Eternal Peace: Problems of Kantian Philosophical Projects

Full Text Available This paper aims to critically analyze the major projects of Kantian philosophy in relation to the ideal of Aufklärung and the establishment of Eternal Peace. The main objective of the research is to analyze the originality and boundaries of Kantian projects both at the level of the practical (moral rationale and at the level of the relations of power and interests of the state actors on the international political scene. We aim to identify the boundaries of the Kantian approach in order to establish Eternal Peace, applying the logic of the power relations existing on the international political scene. The secondary objective of the research is to identify how the individual and the state are projected into Kantian philosophy. The original aspect of this article is the decoding of Kantian critical thinking in relation to the project of Aufklärung and the establishment of Eternal Peace. The main result of the research is that the tension of reasoning applied by philosopher Immanuel Kant regarding the definition of human nature and the relationship of forces on the international political scene. Applying the practical (moral rationale used to define the individual’s inclination to get out of the minority state (by knowledge becomes problematic at the time of the Kantian approach to justify the (political necessity of Eternal Peace.

Ceramic Technology Project. Semiannual progress report for April 1993 through September 1993

Energy Technology Data Exchange (ETDEWEB)

1994-04-01

The Ceramic Technology Project was originally developed by the Department of Energy`s Office of Transportation Systems (OTS) in Conservation and Renewable Energy. This project, part of the OTS`s Materials Development Program, was developed to meet the ceramic technology requirements of the OTS`s automotive technology programs. During the course of the Ceramic Technology Project, remarkable progress has been made in the development of reliable structural ceramics. However, further work is needed to reduce the cost of ceramics to facilitate their commercial introduction, especially in the highly cost-sensitive automotive market. The work described in this report is organized according to the following WBS project elements: Project Management and Coordination; Materials and Processing; Materials Design Methodology; Data Base and Life Prediction; and Technology Transfer. This report includes contributions from all currently active project participants. Separate abstracts were prepared for the 47 projects reported here.

There are numerous anatomical variations of the sites of origin of the bronchial arteries (BAs). A subclavian origin of a BA involves an aberrant artery that originates from the subclavian artery (SCA) or its branches. However, the aberrant artery usually originates directly from the SCA, and an SCA-origin BA arising from the branches of the SCA is rare. We herein present an extremely rare case of a right BA arising from the ipsilateral costocervical trunk, and a left BA arising from the ipsilateral thyrocervical trunk, in the absence of other origins of the BA. This anatomical variation was detected during pretherapeutic evaluation by multidetector-row computed tomography and confirmed by selective angiography. Recognition of these anatomic variations is important to surgical, diagnostic, and interventional radiologic procedures in the thorax.

Full Text Available This paper reviews the novel use of CT and MRI data and image processing tools to segment and reconstruct tissue images in 3D to determine characteristics of muscle, bone and brain.This to study and simulate the structural changes occurring in healthy and pathological conditions as well as in response to clinical treatments. Here we report the application of this methodology to evaluate and quantify: 1. progression of atrophy in human muscle subsequent to permanent lower motor neuron (LMN denervation, 2. muscle recovery as induced by functional electrical stimulation (FES, 3. bone quality in patients undergoing total hip replacement and 4. to model the electrical activity of the brain. Study 1: CT data and segmentation techniques were used to quantify changes in muscle density and composition by associating the Hounsfield unit values of muscle, adipose and fibrous connective tissue with different colors. This method was employed to monitor patients who have permanent muscle LMN denervation in the lower extremities under two different conditions: permanent LMN denervated not electrically stimulated and stimulated. Study 2: CT data and segmentation techniques were employed, however, in this work we assessed bone and muscle conditions in the pre-operative CT scans of patients scheduled to undergo total hip replacement. In this work, the overall anatomical structure, the bone mineral density (BMD and compactness of quadriceps muscles and proximal femoral was computed to provide a more complete view for surgeons when deciding which implant technology to use. Further, a Finite element analysis provided a map of the strains around the proximal femur socket when solicited by typical stresses caused by an implant press fitting. Study 3 describes a method to model the electrical behavior of human brain using segmented MR images. The aim of the work is to use these models to predict the electrical activity of the human brain under normal and pathological

We analyse generosity, second-party ('spiteful') punishment (2PP), and third-party ('altruistic') punishment (3PP) in a cross-cultural experimental economics project. We show that smaller societies are less generous in the Dictator Game but no less prone to 2PP in the Ultimatum Game. We might assume people everywhere would be more willing to punish someone who hurt them directly (2PP) than someone who hurt an anonymous third person (3PP). While this is true of small societies, people in large societies are actually more likely to engage in 3PP than 2PP. Strong reciprocity, including generous offers and 3PP, exists mostly in large, complex societies that face numerous challenging collective action problems. We argue that 'spiteful' 2PP, motivated by the basic emotion of anger, is more universal than 3PP and sufficient to explain the origins of human cooperation.

The rise and fall of a second-generation CBNRM project in Zambia: insights from a project perspective.

Science.gov (United States)

Lyons, Andrew

2013-02-01

Since the advent of community-based natural resource management (CBNRM) in the mid-1980s, scholars and practitioners have sought to explain the uneven performance of CBNRM programs. Most CBNRM assessments examine the underlying principles of community-based conservation, the local social and ecological contexts, and connections with larger political and historical patterns. In this article, I argue that analysis of the potential and pitfalls of CBNRM also requires an understanding of the institutional history and internal dynamics of projects that implement CBNRM reforms. Drawing upon theory and methods from development ethnography and public policy, I examine the rise and fall of CONASA, a second-generation CBNRM project in Zambia that operated from 2001 to 2004. CONASA was constituted from a merger of organizations and discourses to provide continuity with previous projects. Its ambitious suite of activities included support for household livelihoods, community-based resource management, policy analysis, advocacy, and conservation enterprises at local, national, and transboundary levels. While individual activities were largely successful, CONASA's hybrid origins and logframe-centric management created fissures between its holistic design and operational logics, and hindered its ability to develop a broader narrative and maintain key alliances. This case study illustrates the importance of understanding the interplay between project design and operational context to fully appreciate the possibilities and limitations of project-mode conservation.

The Origin of Language

2018-01-01

There have been a lot of discussions of the origin of language. Some people think that the origin of words is onomatopoeias. Meanwhile, according to expressive theories, the origin of words and language is the innate cries of pain or pleasure produced by nonhuman animals. Others insist that language originated as a means of communication. Another theory holds that a learned vocalization systems, more like birdsong than innate calls, formed a middle term in language evolution. Others claim tha...

Sipes, Carolyn

2016-01-01

With the evolution of nursing informatics (NI), the list of skills has advanced from the original definition that included 21 competencies to 168 basic competencies identified in the TIGER-based Assessment of Nursing Informatics Competencies (TANIC) and 178 advanced skills in the Nursing Informatics Competency Assessment (NICA) L3/L4 developed by Chamberlain College of Nursing, Nursing Informatics Research Team (NIRT). Of these competencies, project management is one of the most important essentials identified since it impacts all areas of NI skills and provides an organizing framework for processes and projects including skills such as design, planning, implementation, follow-up and evaluation. Examples of job roles that specifically require project management skills as an essential part of the NI functions include management, administration, leadership, faculty, graduate level master's and doctorate practicum courses. But first, better understanding of the NI essential skills is vital before adequate education and training programs can be developed.

The widely-used LMS algorithm for coefficient updates in adaptive (feedforward/decision-feedback) equalizers is found to be suboptimal for ASE-dominant systems but various coefficient-dithering approaches suffer from slow adaptation rate without guarantee of convergence. In view of the non-Gaussian nature of optical noise after the square-law optoelectronic conversion, we propose to apply the higher-order least-mean 2 th-order (LMN) algorithms resulting in OSNR penalty which is 1.5–2 d...

Lesion insertion in the projection domain: Methods and initial results

Chen, Baiyu; Leng, Shuai; Yu, Lifeng; Yu, Zhicong; Ma, Chi; McCollough, Cynthia

2015-01-01

Purpose: To perform task-based image quality assessment in CT, it is desirable to have a large number of realistic patient images with known diagnostic truth. One effective way of achieving this objective is to create hybrid images that combine patient images with inserted lesions. Because conventional hybrid images generated in the image domain fails to reflect the impact of scan and reconstruction parameters on lesion appearance, this study explored a projection-domain approach. Methods: Lesions were segmented from patient images and forward projected to acquire lesion projections. The forward-projection geometry was designed according to a commercial CT scanner and accommodated both axial and helical modes with various focal spot movement patterns. The energy employed by the commercial CT scanner for beam hardening correction was measured and used for the forward projection. The lesion projections were inserted into patient projections decoded from commercial CT projection data. The combined projections were formatted to match those of commercial CT raw data, loaded onto a commercial CT scanner, and reconstructed to create the hybrid images. Two validations were performed. First, to validate the accuracy of the forward-projection geometry, images were reconstructed from the forward projections of a virtual ACR phantom and compared to physically acquired ACR phantom images in terms of CT number accuracy and high-contrast resolution. Second, to validate the realism of the lesion in hybrid images, liver lesions were segmented from patient images and inserted back into the same patients, each at a new location specified by a radiologist. The inserted lesions were compared to the original lesions and visually assessed for realism by two experienced radiologists in a blinded fashion. Results: For the validation of the forward-projection geometry, the images reconstructed from the forward projections of the virtual ACR phantom were consistent with the images physically

Méndez, B. J. H.

2008-06-01

In recent years, several space science research projects have enlisted the help of large numbers of non-professional volunteers, ``citizen scientists'', to aid in performing tasks that are critical to a project, but require more person-time (or computing time) than a small professional research team can practically perform themselves. Examples of such projects include SETI@home, which uses time from volunteers computers to process radio-telescope observation looking for signals originating from extra-terrestrial intelligences; Clickworkers, which asks volunteers to review images of the surface of Mars to identify craters; Spacewatch, which used volunteers to review astronomical telescopic images of the sky to identify streaks made by possible Near Earth Asteroids; and Stardust@home, which asks volunteers to review ``focus movies'' taken of the Stardust interstellar dust aerogel collector to search for possible impacts from interstellar dust particles. We shall describe these and other similar projects and discuss lessons learned from carrying out such projects, including the educational opportunities they create.

A new project on the solar energetic particles (SEPs) and their solar origins (flares and coronal mass ejections) is described here. The main aim of this project is to answer the question - whether the SEPs observed in situ are driven by flares, by CMEs or both accelerators contribute to an extent which varies from event to event - by deducing a quantitative measure of the flare vs. CME contribution, duration and efficiency. New observations (SONG/Koronas-F, Relec/Vernov) and new approaches of analysis will be utilized (e.g., magnetic topology of active regions using 3D extrapolation techniques of detailed case studies together with statistical analysis of the phenomena). In addition, the identification of the uncertainty limits of SEP injection, onset time and testing the validity of assumptions often taken for granted (association procedures, solar activity longitudinal effects, correlation analysis, etc.) are planned. The project outcomes have the capacity to contribute to other research fields for improvement of modeling schemes and forecasting methods of space weather events.

Correcting a Persistent Manhattan Project Statistical Error

Reed, Cameron

2011-04-01

In his 1987 autobiography, Major-General Kenneth Nichols, who served as the Manhattan Project's ``District Engineer'' under General Leslie Groves, related that when the Clinton Engineer Works at Oak Ridge, TN, was completed it was consuming nearly one-seventh (~ 14%) of the electric power being generated in the United States. This statement has been reiterated in several editions of a Department of Energy publication on the Manhattan Project. This remarkable claim has been checked against power generation and consumption figures available in Manhattan Engineer District documents, Tennessee Valley Authority records, and historical editions of the Statistical Abstract of the United States. The correct figure is closer to 0.9% of national generation. A speculation will be made as to the origin of Nichols' erroneous one-seventh figure.

Physico-chemical processes leading to the dynamic formation and physical evolution of comets are reviewed in relationship to the various theories that propose solar origins, protoplanetary origins, planetary origins and interstellar origins. Evidence points to the origins of comets by the growth and agglomeration of small particles from gas and dust at very low temperatures at undetermined regions in space.

Projective configurations in projectivegeometrical drawings

2015-05-01

Full Text Available The article focuses on the optimization of the earlier discussed computer method of obtaining new forms of polyhedra based on projective geometry drawings (trace Diagrams.While working on getting new multifaceted forms by projective geometry methods based on the well-known models of polyhedra on the first stage of the work it is required to calculate the parameters of projective geometry drawings, and then to build them. This is an often used apparatus of analytical geometry. According to it, at first the parameters of the polyhedron (core system of planes are calculated, then we obtain the equation of the plane of the face of the polyhedron, and finally we obtain the equations of lines the next plane faces on the selected curve plane. At each stage of application such a method requires the use of the algorithms of floating point arithmetic, on the one hand, leads to some loss of accuracy of the results and, on the other hand, the large amount of computer time to perform these operations in comparison with integer arithmetic operations.The proposed method is based on the laws existing between the lines that make up the drawing - the known configurations of projective geometry (complete quadrilaterals, configuration of Desargues, Pappus et al..The authors discussed in detail the analysis procedure of projective geometry drawing and the presence of full quadrilaterals, Desargues and Pappus configurations in it.Since the composition of these configurations is invariant with respect to projective change of the original nucleus, knowing them, you can avoid the calculations when solving the equations for finding direct projective geometry drawing analytically, getting them on the basis of belonging to a particular configuration. So you can get a definite advantage in accuracy of the results, and in the cost of computer time. Finding these basic configurations significantly enriches the set of methods and the use of projective geometry drawings.

Image reconstruction technique using projection data from neutron tomography system

Directory of Open Access Journals (Sweden)

Waleed Abd el Bar

2015-12-01

Full Text Available Neutron tomography is a very powerful technique for nondestructive evaluation of heavy industrial components as well as for soft hydrogenous materials enclosed in heavy metals which are usually difficult to image using X-rays. Due to the properties of the image acquisition system, the projection images are distorted by several artifacts, and these reduce the quality of the reconstruction. In order to eliminate these harmful effects the projection images should be corrected before reconstruction. This paper gives a description of a filter back projection (FBP technique, which is used for reconstruction of projected data obtained from transmission measurements by neutron tomography system We demonstrated the use of spatial Discrete Fourier Transform (DFT and the 2D Inverse DFT in the formulation of the method, and outlined the theory of reconstruction of a 2D neutron image from a sequence of 1D projections taken at different angles between 0 and π in MATLAB environment. Projections are generated by applying the Radon transform to the original image at different angles.

Preserving the Manhattan Project

When future generations look back on the 20th century, few events will rival the harnessing of nuclear energy as a turning point in world history, science and society. Yet, the Department of Energy has not always embraced its Manhattan Project origins. The presentation will focus on the progress made over the last 20 years to preserve the properties and first-hand accounts that for decades have been threatened with demolition and indifference. Since the mid-1950s, most remaining Manhattan Project properties at the Los Alamos National Laboratory had been abandoned. Among them was a cluster of wooden buildings called the ``V Site.'' This is where scientists assembled the ``Gadget,'' the world's first atomic device tested on July 16, 1945. Regardless of its significance, the ``V Site'' buildings like all the rest were slated for demolition. The Advisory Council on Historic Preservation (ACHP) toured the properties in November 1998. Most could not believe that the world's first atomic bomb was designed in such humble structures. The properties were declared to be ``monumental in their lack of monumentality.'' A Save America's Treasures grant for 700,000 was awarded to restore the properties. To raise the required matching funds, I left the Federal government and soon founded the Atomic Heritage Foundation. The presentation will trace the progress made over the last decade to generate interest and support nationwide to preserve the Manhattan Project heritage. Saving both the physical properties and first-hand accounts of the men and women have been a priority. Perhaps our most significant achievement may be legislation now under consideration by Congress to create a Manhattan Project National Historical Park. Seventy years later, the Manhattan Project is finally getting the recognition it deserves.

Innovative value offerings encompass a complex network of suppliers and subcontractors that is not stable and is arranged in a sporadic and unpredictable manner. Multiple case studies in the yacht industry were conducted to explore the configuration of project-service solutions. The research constitutes an original contribution to studies on servitization adoption in an industrial project context from an inter-organizational perspective. It emerged that SMEs reorganize themselves, in order to provide flexible on-demand solutions to customers, by including all the capabilities within their network. Newly arising professional roles are oriented to the implementation of smart networks and are focused on service infusion in order to provide increased customer value.

Reading the Austen Project

Full Text Available The Austen Project: Jane Austen Re-imagined pairs six bestselling contemporary authors with Jane Austen’s six complete works. I propose to use this interesting (though obviously commercially based project to return to the intriguing critical issue of Jane Austen’s voice. How do the individual authors, all with established styles and audiences, deal with these demands? Whose voice does the reader hear in the narrative commentary? What is the difference, affectively, between the style and tone of the original novel and that of a contemporary writer who is not writing a pastiche but re-telling the story in modern terms? Equivalences in plot and characters are easy enough to do, and the re-imaginings so far published provide the modern reader with some delighted and/or surprised recognitions. But Austen’s famous irony, her rendition of the heroine’s thoughts from inside but also ‘beside’ the character’s viewpoint, her oblique critiques of her society and its manners – can they be re-imagined and re-rendered successfully?

A joint project between Mayo Clinic and IBM to develop a picture archival and communications system has been under development for three years. This project began as a potential solution to a pressing archival problem in magnetic resonance imaging. The project has grown to encompass a much larger sphere of activity including workstations, image retrieval, and report archival. This report focuses on the clinical aspects involved in the design, development, and implementation of such a system. In particular, emphasis is placed on the clinical impact of the system both inside and outside of the radiology department. The primary concerns have centered on fidelity of archival data, ease of use, and diagnostic efficacy. The project to date has been limited to neuroradiology practice. This group consists of nine staff radiologists and fellows. Administrative policy decisions regarding the accessibility and available of digital data in the clinical environment have been much more difficult and complex than originally conceived. Based on the observations thus far, the authors believe the system will become a useful and valuable adjunct to clinical practice of radiology.

West Hackberry Tertiary Project. Annual report, September 3, 1997--September 2, 1998

Energy Technology Data Exchange (ETDEWEB)

Gillham, T.H.

1997-09-10

The following report is the Project Management Plan for the fifth year of the West Hackberry Tertiary Project. The West Hackberry Tertiary Project is one of four mid-term projects selected by the United States Department of Energy (DOE) as part of the DOE`s Class 1 Program for the development of advance recovery technologies in fluvial dominated deltaic reservoirs. The West Hackberry Tertiary Project is a field test of the idea that air injection can be combined with the Double Displacement Process to produce a low cost tertiary recovery process which is economic at current oil prices. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering tertiary oil by gravity drainage. The Double Displacement Process is based upon the concept that in fields such as West Hackberry waterdrive recoveries are typically 50%-60% of the original oil in place while gravity drainage recoveries average 80%-90% of the original oil in place. Therefore, by injecting a gas into a watered out reservoir, a gas cap will form an additional oil can be recovered due to gravity drainage. Although the Double Displacement Process has been shown to be successful in recovering tertiary oil in other fields, this project will be the first to utilize air injection in the Double Displacement Process. The use of air injection in this process combines the benefits of air`s low cost and universal accessibility with the potential for accelerated oil recovery due to the combustion process. If successful, this project will demonstrate that the use of air injection in the Double Displacement Process will result in an economically viable tertiary process in reservoirs where tertiary oil recovery is presently uneconomical.

DESIGN VERIFICATION REPORT SPENT NUCLEAR FUEL (SNF) PROJECT CANISTER STORAGE BUILDING (CSB)

BAZINET, G.D.

2003-02-12

The Sub-project W379, ''Spent Nuclear Fuel Canister Storage Building (CSB),'' was established as part of the Spent Nuclear Fuel (SNF) Project. The primary mission of the CSB is to safely store spent nuclear fuel removed from the K Basins in dry storage until such time that it can be transferred to the national geological repository at Yucca Mountain Nevada. This sub-project was initiated in late 1994 by a series of studies and conceptual designs. These studies determined that the partially constructed storage building, originally built as part of the Hanford Waste Vitrification Plant (HWVP) Project, could be redesigned to safely store the spent nuclear fuel. The scope of the CSB facility initially included a receiving station, a hot conditioning system, a storage vault, and a Multi-Canister Overpack (MCO) Handling Machine (MHM). Because of evolution of the project technical strategy, the hot conditioning system was deleted from the scope and MCO welding and sampling stations were added in its place. This report outlines the methods, procedures, and outputs developed by Project W379 to verify that the provided Structures, Systems, and Components (SSCs): satisfy the design requirements and acceptance criteria; perform their intended function; ensure that failure modes and hazards have been addressed in the design; and ensure that the SSCs as installed will not adversely impact other SSCs. The original version of this document was prepared by Vista Engineering for the SNF Project. Revision 1 documented verification actions that were pending at the time the initial report was prepared. Revision 3 of this document incorporates MCO Cover Cap Assembly welding verification activities. Verification activities for the installed and operational SSCs have been completed.

From a unique standpoint, the timber industry in Jepara is deeply rooted to the culture and identity of the natives, making the attempt to separate the discussion between timber industry and the people of Jepara not only  imprudent but virtually impossible. By looking at the statistic in which Jepara’s public education level is assessed to be still below the national standard, and as well bearing to the general fact that the timber actors in Jepara are more focused on product sales rather than important technical aspects such as certification of origin, it should be projected that crimes such as fraud of origin could be easily committed in Jepara. This study is using a comparative advantage theory and theories or models of H-O to investigate how the practice of fraud of origin in Jepara occurs and how to resolve such problem.

The fissile mass in radioactive waste drums filled with compacted metallic residues (spent fuel hulls and nozzles) produced at AREVA NC La Hague reprocessing plant is measured by neutron interrogation with the Differential Die-away measurement Technique (DDT). In the next years, old hulls and nozzles mixed with Ion-Exchange Resins will be measured. The ion-exchange resins increase neutron moderation in the matrix, compared to the waste measured in the current process. In this context, the Nuclear Measurement Laboratory (LMN) of CEA Cadarache has studied a matrix effect correction method, based on a drum monitor, namely a 3He proportional counter located inside the measurement cavity. After feasibility studies performed with LMN's PROMETHEE 6 laboratory measurement cell and with MCNPX simulations, this paper presents first experimental tests performed on the industrial ACC (hulls and nozzles compaction facility) measurement system. A calculation vs. experiment benchmark has been carried out by performing dedicated calibration measurements with a representative drum and {sup 235}U samples. The comparison between calculation and experiment shows a satisfactory agreement for the drum monitor. The final objective of this work is to confirm the reliability of the modeling approach and the industrial feasibility of the method, which will be implemented on the industrial station for the measurement of historical wastes.

Hereditary spastic paraplegia: More than an upper motor neuron disease.

Science.gov (United States)

Parodi, L; Fenu, S; Stevanin, G; Durr, A

2017-05-01

Hereditary spastic paraplegias (HSPs) are a group of rare inherited neurological diseases characterized by extreme heterogeneity in both their clinical manifestations and genetic backgrounds. Based on symptoms, HSPs can be divided into pure forms, presenting with pyramidal signs leading to lower-limb spasticity, and complex forms, when additional neurological or extraneurological symptoms are detected. The clinical diversity of HSPs partially reflects their underlying genetic backgrounds. To date, 76 loci and 58 corresponding genes [spastic paraplegia genes (SPGs)] have been linked to HSPs. The genetic diagnosis is further complicated by the fact that causative mutations of HSP can be inherited through all possible modes of transmission (autosomal-dominant and -recessive, X-linked, maternal), with some genes showing multiple inheritance patterns. The pathogenic mutations of SPGs primarily lead to progressive degeneration of the upper motor neurons (UMNs) comprising corticospinal tracts. However, it is possible to observe lower-limb muscle atrophy and fasciculations on clinical examination that are clear signs of lower motor neuron (LMN) involvement. The purpose of this review is to classify HSPs based on their degree of motor neuron involvement, distinguishing forms in which only UMNs are affected from those involving both UMN and LMN degeneration, and to describe their differential diagnosis from diseases such as amyotrophic lateral sclerosis.

Feed-forward and feedback projections of midbrain reticular formation neurons in the cat

Directory of Open Access Journals (Sweden)

Eddie ePerkins

2014-01-01

Full Text Available Gaze changes involving the eyes and head are orchestrated by brainstem gaze centers found within the superior colliculus (SC, paramedian pontine reticular formation (PPRF, and medullary reticular formation (MdRF. The mesencephalic reticular formation (MRF also plays a role in gaze. It receives a major input from the ipsilateral SC and contains cells that fire in relation to gaze changes. Moreover, it provides a feedback projection to the SC and feed-forward projections to the PPRF and MdRF. We sought to determine whether these MRF feedback and feed-forward projections originate from the same or different neuronal populations by utilizing paired fluorescent retrograde tracers in cats. Specifically, we tested: 1. whether MRF neurons that control eye movements form a single population by injecting the SC and PPRF with different tracers, and 2. whether MRF neurons that control head movements form a single population by injecting the SC and MdRF with different tracers. In neither case were double labeled neurons observed, indicating that feedback and feed-forward projections originate from separate MRF populations. In both cases, the labeled reticulotectal and reticuloreticular neurons were distributed bilaterally in the MRF. However, neurons projecting to the MdRF were generally constrained to the medial half of the MRF, while those projecting to the PPRF, like MRF reticulotectal neurons, were spread throughout the mediolateral axis. Thus, the medial MRF may be specialized for control of head movements, with control of eye movements being more widespread in this structure.

Economic case for CANDU life extension projects

International Nuclear Information System (INIS)

Qureshi, S.; Tenev, T.; Lewi, M.

2014-01-01

As CANDU reactors approach their original end of design life utilities are faced with two options: to extend the operating life of the reactor by undergoing a life extension project (LEP), or to commence decommissioning activities. Recent project experience has shown that there is economic merit in extending the life of the operating reactor. There are many benefits to such a decision, the most obvious being the revenue that will be generated from the additional years of electricity production by the utility. Delays in decommissioning are also advantageous since the large costs associated with such a long-term activity are pushed into the future, thereby decreasing the net present value (NPV) of the investment. In addition, relatively few power reactors have been fully decommissioned to date and deferring this activity transfers the associated risks to others that are currently obligated to undertake decommissioning activities sooner. Candu Energy has been involved with the life extension projects of the following CANDU reactors: Point Lepreau (New Brunswick, Canada), Bruce Unit 1 and Unit 2 (Ontario, Canada), and Wolsong Unit 1 (South Korea). These reactors underwent fuel channel replacement programs in addition to replacement of major reactor components. Most recently, both Ontario Power Generation (OPG) and Nucleoelectrica Argentina Sociedad Anonima (NA-SA) have commenced work on life extension projects at the Darlington (Canada) and Embalse (Argentina) sites respectively. The experience gained from previous LEP projects allows Candu Energy to deliver future projects in a timely, efficient, and cost effective manner. (author)

Creativity in Numbers and Words:The Analysis of Divergence in Creative Project Perception

Alina Kozarkiewicz

2018-05-01

Full Text Available Aim/purpose - The main purpose of this paper is to identify the necessity of distinguishing a particular taxonomic group termed creative projects. Is it a peculiar, distinctive type of projects, or nowadays every project can be denominated 'creative'? The research aims at comparing the ways of understanding and defining this term in prior literature and in the opinions of practitioners involved in everyday project management and realization. Design/methodology/approach - The paper is divided into main parts corresponding to research objectives: first, the results of literature research is demonstrated briefly, and next the results of empirical research are delineated. The empirical research was conducted with mixed methods. The quantitative part conducted as CAWI was supported by Poll Everywhere platform, the qualitative investigations were supported by MAXQDA software. Findings - According to research results, there exists the inconsistency among the views of researchers, as well as practitioners. As the literature review reveals, there are various stances towards this issue: from silent assumption that the concept does not require to be defined till some analyses of the relations between routine and creative actions. Similar variety was disclosed when analyzing practitioners' judgments. Research implications/limitations - The divergence in opinions as to the necessity of distinguishing a particular taxon of creative projects as well as the broad variety of opinions as to their specific characteristics have given rise to the call for more precise framing scientific research on creative projects. The research has numerous limitations result-ing from its scope, sampling method or sample size, however, it demonstrates the absence of coherent views and variety of arguments used.Originality/value/contribution - Apart from urging the more rigorous frames of research on creative projects, the paper indicates new avenues of investigations oriented

An accurate projection algorithm for array processor based SPECT systems

International Nuclear Information System (INIS)

King, M.A.; Schwinger, R.B.; Cool, S.L.

1985-01-01

A data re-projection algorithm has been developed for use in single photon emission computed tomography (SPECT) on an array processor based computer system. The algorithm makes use of an accurate representation of pixel activity (uniform square pixel model of intensity distribution), and is rapidly performed due to the efficient handling of an array based algorithm and the Fast Fourier Transform (FFT) on parallel processing hardware. The algorithm consists of using a pixel driven nearest neighbour projection operation to an array of subdivided projection bins. This result is then convolved with the projected uniform square pixel distribution before being compressed to original bin size. This distribution varies with projection angle and is explicitly calculated. The FFT combined with a frequency space multiplication is used instead of a spatial convolution for more rapid execution. The new algorithm was tested against other commonly used projection algorithms by comparing the accuracy of projections of a simulated transverse section of the abdomen against analytically determined projections of that transverse section. The new algorithm was found to yield comparable or better standard error and yet result in easier and more efficient implementation on parallel hardware. Applications of the algorithm include iterative reconstruction and attenuation correction schemes and evaluation of regions of interest in dynamic and gated SPECT

Projection of curves on B-spline surfaces using quadratic reparameterization

KAUST Repository

Yang, Yijun

2010-09-01

Curves on surfaces play an important role in computer aided geometric design. In this paper, we present a hyperbola approximation method based on the quadratic reparameterization of Bézier surfaces, which generates reasonable low degree curves lying completely on the surfaces by using iso-parameter curves of the reparameterized surfaces. The Hausdorff distance between the projected curve and the original curve is controlled under the user-specified distance tolerance. The projected curve is T-G 1 continuous, where T is the user-specified angle tolerance. Examples are given to show the performance of our algorithm. © 2010 Elsevier Inc. All rights reserved.

Coupled rolling motion: a student project in non-holonomic mechanics

International Nuclear Information System (INIS)

Janova, Jitka; Musilova, Jana; Bartos, JirI

2009-01-01

This paper presents an original undergraduate student project in theoretical mechanics: a demonstration of theory and experiment agreement inspired by a recently theoretically treated mechanical problem of coupled rolling motion of two cylinders. The problem of a mechanical system subjected to non-holonomic constraints is theoretically and numerically solved. Subsequently, the solution is quantitatively verified by a simple and inexpensive experiment, originally proposed and constructed by the authors. The comparison of results of the theoretical study with experimental output shows that there are instruments to directly verify rather abstract mathematical theories even on the undergraduate level. Moreover, combining the theoretical description of the problem with an appropriate laboratory experiment and computational procedures gives students a more complex view of the physical problem as a whole. This paper can be used by physics teachers on the undergraduate university level as an inspiration for an interesting student project. Moreover, the theoretical part of this paper itself can be used by interested intermediate students themselves as a good exercise in theoretical mechanics.

Objective: to observe the origin site, anatomic features of uterine artery with 3D DSA and to discuss the optimal projection position in order to improve the success rate of super-selective catheterization of uterine artery. Methods: Prospective pelvic angiography was performed in 42 adult females (a total of 84 uterine arteries). 3D DSA was carried out with 206 ° rotation. 3D reconstruction of the obtained images was performed and the angiographic manifestations of the uterine artery were analyzed. The optimal projection position for the displaying of uterine artery was discussed. The quality of images obtained with the projection angle of 15 °-25 °, 25 °-35 ° and 35 °-45 ° was determined and the results were compared with each other. Results: The orifices of all 84 uterine arteries could be well demonstrated on 3D DSA images. The uterine artery was originated from the anterior trunk of internal iliac artery (n=58, 69%), from main stem of internal iliac artery (n=16, 19.1%), from internal pudenda artery (n=8, 9.5%) and from inferior gluteal artery (n=2, 2.4%). The best projection position to show the opening and route of the uterine artery was contralateral oblique view of 25-35 degrees (P<0.05). Conclusion: 3D DSA can clearly display the anatomy of the uterine artery, which is very helpful for the management of super-selective catheterization of uterine artery. The optimal projection position for uterine artery is contralateral oblique view of 25-35 degrees. (authors)

Revisiting the theoretical basis of the endosymbiotic origin of plastids in the original context of Lynn Margulis on the origin of mitosing, eukaryotic cells.

Science.gov (United States)

Sato, Naoki

2017-12-07

Fifty years ago, Lynn Margulis proposed a comprehensive hypothesis on the origin of eukaryotic cells with an emphasis on the origin of mitosis. This hypothesis postulated that the eukaryotic cell is a composite of different parts as a result of the symbiosis of various different bacteria. In this hypothesis, she integrated previously proposed ideas that mitochondria and chloroplasts were descendants of endosymbionts that originated from aerobic bacteria and blue-green algae (now cyanobacteria), respectively. However, the major part of her hypothesis, which she believed to be original, was the origin of mitosis. The core of her postulate involved a chromosome partition mechanism dependent on DNA-microtubule binding, which originated from a hypothetical centriole-DNA complex, with an ability to replicate. Surprisingly, her complete lack of real experimental works in the cytoskeleton, cell motility, or paleontology did not prevent this 29-year-old junior scientist from assembling archival knowledge and constructing a narrative on the evolution of all organisms. Whether the centriole-DNA complex originated from a spirochete or not was a minor anecdote in this initial postulate. Unfortunately, this hypothesis on the origin of mitosis, which she believed to be a holistic unity, testable by experiments, was entirely refuted. Despite falsification of her original narrative as a whole, her success as a founder of endosymbiotic theory on the origin of mitochondria and chloroplasts is undoubted. We will discuss the reasons for her success in terms of the historical situation in the latter half of the 20th century. Copyright © 2017 Elsevier Ltd. All rights reserved.

1993-01-01

On February 17,1989, the Midwestern Office of The Council of State Governments and the US Department of Energy entered into a cooperative agreement authorizing the initiation of the Midwestern High-Level Radioactive Waste Transportation Project. The transportation project continued to receive funding from DOE through amendments to the original cooperative agreement, with December 31, 1993, marking the end of the initial 5-year period. This progress report reflects the work completed by the Midwestern Office from February 17,1989, through December 31,1993. In accordance with the scopes of work governing the period covered by this report, the Midwestern Office of The Council of State Governments has worked closely with the Midwestern High-Level Radioactive Waste Committee. Project staff have facilitated all eight of the committee's meetings and have represented the committee at meetings of DOE's Transportation Coordination Group (TCG) and Transportation External Coordination Working Group (TEC/WG). Staff have also prepared and submitted comments on DOE activities on behalf of the committee. In addition to working with the committee, project staff have prepared and distributed 20 reports, including some revised reports (see Attachment 1). Staff have also developed a library of reference materials for the benefit of committee members, state officials, and other interested parties. To publicize the library, and to make it more accessible to potential users, project staff have prepared and distributed regular notices of resource availability

A Conceptual Grey Analysis Method for Construction Projects

Directory of Open Access Journals (Sweden)

Maria Mikela Chatzimichailidou

2015-05-01

Full Text Available Concerning engineers, project management is a crucial field of research and development. Projects of high uncertainty and scale are characterized by risk, primarily related to their completion time. Thus, safe duration estimations, throughout the planning of a project, are a key objective for project managers. However, traditional linear approaches fail to include and sufficiently serve the dynamic nature of activities duration. On this ground, attention should be paid to designing and implementing methodologies that approximate the duration of the activities during the phase of planning and scheduling too. The grey analysis mathematical modeling seems to gain grounds, since it gradually becomes a well-adapted and up-to-date technique for numerous scientific sectors. This paper examines the contribution of the logic behind the aforementioned analysis, aiming to predict possible future divergences of task durations in big construction projects. Based on time observations of critical instances, a conceptual method is developed for making duration estimations and communicating deviations from the original schedule, in a way that approximations will fit reality better. The whole procedure endeavors to investigate the decrease of uncertainty, regarding project completion time and reduce, up to a scale, a possible inaccurate estimation of a project manager. The utmost effort is about exploiting the gained experience and eliminating the “hedgehog syndrome”. This is attainable by designing a reliable, easily updated, and readable information system. An enlightening example is to be found in the last section.

On the geometry of some special projective varieties

CERN Document Server

Russo, Francesco

2016-01-01

Providing an introduction to both classical and modern techniques in projective algebraic geometry, this monograph treats the geometrical properties of varieties embedded in projective spaces, their secant and tangent lines, the behavior of tangent linear spaces, the algebro-geometric and topological obstructions to their embedding into smaller projective spaces, and the classification of extremal cases. It also provides a solution of Hartshorne’s Conjecture on Complete Intersections for the class of quadratic manifolds and new short proofs of previously known results, using the modern tools of Mori Theory and of rationally connected manifolds. The new approach to some of the problems considered can be resumed in the principle that, instead of studying a special embedded manifold uniruled by lines, one passes to analyze the original geometrical property on the manifold of lines passing through a general point and contained in the manifold. Once this embedded manifold, usually of lower codimension, is classi...

A projective approach to a language of landscape design

Directory of Open Access Journals (Sweden)

Catherine Ward Thompson

1997-10-01

Full Text Available Building on the work of Kelly (1955 in personal construct psychology, and Peled (1976, I990 in ecoanalysis, this paper develops projective techniques-which use concepts of personal and phenomenological space-as a means for articulating approaches to landscape design. The projective approach involves two stages. In stage one, projective techniques are used to elicit personal constructs (which may be held at a pre-conscious or sub-conscious level, allowing the holistic experience of landscape to be explored. In stage two, using a 'projection location task' derived from the way we experience and construe the regions of our own bodies, elements of these constructs can then be articulated so as to inform the way we interact and engage with the space around us. This gives insight into the meaning of spatial layouts, which can then be translated into a design language for the structural ordering of space. The author draws on original research conducted with children as well as adults, using projective techniques to draw out their desires and needs in relation to designing their landscape environment. The paper discusses the value of such methods for landscape designers and their clients, and outlines some ongoing research to test the validity of the projection location task.

PERFORMANCE ANALYSIS OF PROJECTS IMPLEMENTATION IN HEIS

Sergiu-Vlad PETCU

2015-04-01

Full Text Available According to the European Commission, Romania is still facing significant mismatch between the skills of graduates of tertiary education and the market needs. This paper is highly relevant for the future implementation of HEIs, since they have a strong economic role and they can significantly influence long-term national social and economical development. Romania did not manage to materialize community funds allocated for the 2007-2013 programming period to its full potential. Accordingly, the proposed thesis intends to analyse how Romanian HEIs were able to manage community resources attracted by grants and how the implemented projects achieved their set objectives. According to the data collected so far, the results will show that the performance of the projects is directly dependent on the proportion of fully dedicated staff in organizational design of the project. The originality of the undertaken study is that it starts from a realistic approach, according to which the rules of the game should be adapted, depending on the players (in our case – HEIs.

Valorization of a repository in an added value project

International Nuclear Information System (INIS)

Van Hove, E.

2004-01-01

Professor of Sociology (retired), spoke of the valorization of a repository in an added value project. He pointed out that though local stakeholders may lack technical expertise, they consider their personal interests very carefully and projects affecting such interests are taken quite personally. This provides caution but also opportunity for such projects to be conducted in ways that can help, though not guarantee, better acceptance by local stakeholders. Professor Van Hove mentioned three attributes. First, while engineering projects tend to be thought of as mono-functional (e.g. dispose of waste), building flexibility into the project to reflect the interests of the local stakeholders can measurably improve Stakeholder satisfaction. What the implementer may see as a single-purpose project may indeed provide additional, desirable capabilities to a creative local population. Second, while engineering projects, particularly waste management projects are often designed and built in uninteresting, utilitarian ways, a more creative design and implementation can add a sense of enjoyment and pride on the part of the local stakeholders. And third, while engineering projects are often conducted a manner closed to their environment, a more transparent, inclusive process may draw local stakeholders more intimately into the project. All of these features can help by providing inviting borders, by valuing the beauty and aesthetic dimension of the project and by building the project so that it has an appropriate place in the memory of society. Professor Van Hove emphasised that people show great ingenuity in adapting uses and functions beyond those originally intended. The extent to which local stakeholders can help provide the vision and then the reality of such waste management projects can significantly improve their sense of ownership of the project and their ultimate acceptance.

Edwards, Mark

2008-04-01

The Advanced Linked Extended Reconnaissance & Targeting (ALERT) Technology Demonstration (TD) project is addressing many operational needs of the future Canadian Army's Surveillance and Reconnaissance forces. Using the surveillance system of the Coyote reconnaissance vehicle as an experimental platform, the ALERT TD project aims to significantly enhance situational awareness by fusing multi-sensor and tactical data, developing automated processes, and integrating beyond line-of-sight sensing. The project is exploiting important advances made in computer processing capability, displays technology, digital communications, and sensor technology since the design of the original surveillance system. As the major research area within the project, concepts are discussed for displaying and fusing multi-sensor and tactical data within an Enhanced Operator Control Station (EOCS). The sensor data can originate from the Coyote's own visible-band and IR cameras, laser rangefinder, and ground-surveillance radar, as well as from beyond line-of-sight systems such as mini-UAVs and unattended ground sensors. Video-rate image processing has been developed to assist the operator to detect poorly visible targets. As a second major area of research, automatic target cueing capabilities have been added to the system. These include scene change detection, automatic target detection and aided target recognition algorithms processing both IR and visible-band images to draw the operator's attention to possible targets. The merits of incorporating scene change detection algorithms are also discussed. In the area of multi-sensor data fusion, up to Joint Defence Labs level 2 has been demonstrated. The human factors engineering aspects of the user interface in this complex environment are presented, drawing upon multiple user group sessions with military surveillance system operators. The paper concludes with Lessons Learned from the project. The ALERT system has been used in a number of C4ISR

The Time Projection Chamber (TPC) is the main particle tracking detector in ALICE. Charged particles crossing the gas of the TPC knock electrons out of their atoms, which drift in the eletric field. By measuring the arrival of electrons at the end of the chamber, at segments such as the one shown here, the TPC will reconstruct the paths of the original charged particles.

Origin of Evolution versus Origin of Life: A Shift of Paradigm

Directory of Open Access Journals (Sweden)

Marc Tessera

2011-06-01

Full Text Available The question of the primordial ancestor must be approached through the search for the origin of evolution, not through the search for the origin of life. There is a major issue with the concept of life because it is impossible to define, thus is not a scientific but a metaphysical concept. On the contrary, evolution may be defined by as few as three conditions. These do not necessarily involve biopolymers. However, such an approach must give clues to explain the emergence of distinct lineages to allow Darwinian natural selection. A plausible solution exists within an autotrophic lipidic vesicle-based model that is presented. The model requires the existence of hydrothermal sites such as the Lost City Hydrothermal Field leading to specific constraints. For this reason Mars and Europa may be questioned as possible cradles of evolution. If we replace the search for the origin of life by the one for the origin of evolution our priority first is to find a consensus on the minimal conditions that would allow evolution to emerge and persist anywhere in the universe.

Neural network algorithm for image reconstruction using the grid friendly projections

International Nuclear Information System (INIS)

Cierniak, R.

2011-01-01

Full text: The presented paper describes a development of original approach to the reconstruction problem using a recurrent neural network. Particularly, the 'grid-friendly' angles of performed projections are selected according to the discrete Radon transform (DRT) concept to decrease the number of projections required. The methodology of our approach is consistent with analytical reconstruction algorithms. Reconstruction problem is reformulated in our approach to optimization problem. This problem is solved in present concept using method based on the maximum likelihood methodology. The reconstruction algorithm proposed in this work is consequently adapted for more practical discrete fan beam projections. Computer simulation results show that the neural network reconstruction algorithm designed to work in this way improves obtained results and outperforms conventional methods in reconstructed image quality.

Stickler, A.; Allan, R.; Valente, M. A.; Tinz, B.; Brönnimann, S.

2012-04-01

Climate science as a whole as well as reanalyses as a special case can significantly profit from the recovery, imaging and digitisation of historical observations. The importance of this fact is reflected in large, global data rescue projects and initiatives such as the Atmospheric Circulation Reconstructions over the Earth (ACRE, www.met-acre.org) or the EU FP7 ERA-CLIM project (www.era-clim.eu). From the time before 1957, there are still large amounts of surface data e.g. from former colonies and from overseas territories of European countries )e.g. Portugal, France and Germany) that need to be rescued. Also in case of the very early upper-air observations before the 1930s, even Europe and North America still hold an important quantity of data to be recovered in digital form. Here, we present the web platform "Data Rescue @ Home" (www.data-rescue-at-home.org), which has been developed at ETH Zurich and Oeschger Centre for Climate Change Research, and which has been designed to take advantage of the voluntary assistance of the thousands of people on the web who are interested in climate or old weather data. On the website, these volunteers can enter meteorological data shown on digital images into entry masks that resemble the original. By registering, the users get access to their personal digitisation statistics and help optimising the project. At the moment, 4 digitisation projects are online: One project is dealing with German upper-air data from the Second World War period. In a second project, station data from Tulagi (Solomon Islands) is being digitised. Finally, two collaborative projects have been included: One in cooperation with the Instituto Dom Luiz (Univ. Lisbon, Portugal), where Portuguese station data from Angra (Azores) is digitised, and a further one in cooperation with the German Meteorological Service (DWD), in which precipitation data from former German colonies is being digitised. On our poster, we will report on the status of the projects

2017-08-01

Recently new JVLA observations by Perley et al. (2017) have revealed evidence for a luminous radio transient at a projected distance of 0.46 kpc from the nucleus of Cygnus A. Based on data taken between 1989 and 2016, the flux density of this radio transient has risen from an upper limit of dimming on this timescale, which we interpret as fading reflected nuclear emission from surrounding dust. In this presentation, we summarize these results and their implications in light of a TDE origin for the observed X-ray and radio variability.

Full Text Available Aim/purpose - The study aims to investigate the relationship among the leadership, operational efficiency and project success in general and the impact of transformational leadership and operational efficiency on project success in particular. Design/methodology/approach - Mean comparison from descriptive statistics and multiple linear regression from inferential statistics was used to determine the association between variables and further impact of the transformational leadership and operational efficiency on project success in the development sector. The paper presents the results of a survey conducted among 200 employees from the top, middle & lower management levels of various national & international development organizations working in Pakistan like Microfinance Banks and other Rural Support Programs. Statistical Package for Social Sciences (SPSS was used to process data. Findings - The result shows positive association among transformational leadership, operational efficiency and project success. In addition, it was found that transformational leadership and operational efficiency have a positive and statistically significant impact on the project success. It is concluded that both transformational leadership and operational efficiency are vital to achieving the optimum level of success in any project, especially in the development sector. Research implications/limitations - The integral limitation of the study was the respondents because most of the development organizations have their operations in rural areas where access was difficult because of limited time and resources. In addition, such organizations are always reluctant to provide survey feedback. Originality/value/contribution - The paper contribution is in the theoretical and practical knowledge of the project success factors in the development sector which is still a somehow unexplored area. Regulators of the development sector may be benefited from this study.

In 1975, the U.S. Government contracted the Jet Propulsion Lab. to develop, by 1985, in conjunction with industry, the photovoltaics (PV) module and array technology required for widespread use of photovoltaics as a significant terrestrial energy source. As a result, a project that eventually became known as the Flat Plate Solar Array (FSA) Project was formed to manage an industry, university, and Government team to perform the necessary research and development. The original goals were to achieve widespread commercial use of PV modules and arrays through the development of technology that would allow them to be profitably sold for $1.07/peak watts (1985 dollars). A 10% module conversion efficiency and a 20 year lifetime were also goals. It is intended that the executive summary provide the means by which one can gain a perspective on 11 years of terrestrial photovoltaic research and development conducted by the FSA Project.

1998-08-01

Spinocerebellar axons have been studied extensively in placental mammals, but there have been no full reports on their origin, laterality, or spinal course in any marsupial. We have used the North American opossum (Didelphis virginiana) to obtain such information and to ask whether any spinocerebellar neurons innervate both the anterior and posterior lobes of the cerebellum through axonal collaterals. To identify spinal neurons that project to the cerebellum, we employed the retrograde transport of Fluoro-Gold (FG) from the anterior lobe, the main target of spinocerebellar axons. In some cases, cerebellar injections of FG were combined with hemisections of the rostral cervical or midthoracic spinal cord, so that laterality of spinocerebellar connections could be established. To determine whether single neurons project to both the anterior lobe and the posterior lobe, injections of Fast Blue (FB) into the anterior lobe were combined with injections of Diamidino yellow (DY) or rhodamine B dextran (RBD) into the posterior lobe, or vice versa. Following injections of FG into the anterior lobe, neurons were labeled throughout the length of the spinal cord, which differed in laminar distribution and laterality of their projections. Among other areas, neurons were labeled in the central cervical nucleus, the nucleus centrobasalis, Clarke's nucleus, the dorsal horn dorsal spinocerebellar tract area, the spinal border region, and Stilling's nucleus. When anterior lobe injections of FB were combined with injections of RBD or DY into the posterior lobe, or vice versa, some double-labeled neurons were present in all major spinocerebellar groups. Cerebellar injections of FG also retrogradely labeled spinocerebellar axons, allowing us to document their locations in the gray matter as well as within the periphery of the lateral and ventral funiculi at all spinal levels. A few spinocerebellar axons also were found in the dorsal funiculus (a dorsal column-spinocerebellar tract

Full Text Available This study treats the members in nonprofit organizations (NPOs as subjects, and explores the origination, planning, control, and completion of project management in NPOs, as well as the general performance of organizational efficacy, such as environmental satisfaction, organizational atmosphere, operational performance, job engagement, and work quality. It also probes into the relationship and effect. By various research methods, such as literature review and questionnaire survey, this study attempts to determine if project management in NPOs can significantly enhance organizational efficacy. This study finds that different NPOs have significant differences in the general performance of project management and organizational efficacy. When the performance of project management in NPOs is more significant, organizational efficacy is higher. Project management in NPOs has a significant path relationship to organizational efficacy; therefore, reinforcement of vocational training in the project management of NPOs could improve performance, which would have significant effect on enhancing organizational efficacy.

Information mining in weighted complex networks with nonlinear rating projection

Liao, Hao; Zeng, An; Zhou, Mingyang; Mao, Rui; Wang, Bing-Hong

2017-10-01

Weighted rating networks are commonly used by e-commerce providers nowadays. In order to generate an objective ranking of online items' quality according to users' ratings, many sophisticated algorithms have been proposed in the complex networks domain. In this paper, instead of proposing new algorithms we focus on a more fundamental problem: the nonlinear rating projection. The basic idea is that even though the rating values given by users are linearly separated, the real preference of users to items between the different given values is nonlinear. We thus design an approach to project the original ratings of users to more representative values. This approach can be regarded as a data pretreatment method. Simulation in both artificial and real networks shows that the performance of the ranking algorithms can be improved when the projected ratings are used.

Hoxb1 controls anteroposterior identity of vestibular projection neurons.

Science.gov (United States)

Chen, Yiju; Takano-Maruyama, Masumi; Fritzsch, Bernd; Gaufo, Gary O

2012-01-01

The vestibular nuclear complex (VNC) consists of a collection of sensory relay nuclei that integrates and relays information essential for coordination of eye movements, balance, and posture. Spanning the majority of the hindbrain alar plate, the rhombomere (r) origin and projection pattern of the VNC have been characterized in descriptive works using neuroanatomical tracing. However, neither the molecular identity nor developmental regulation of individual nucleus of the VNC has been determined. To begin to address this issue, we found that Hoxb1 is required for the anterior-posterior (AP) identity of precursors that contribute to the lateral vestibular nucleus (LVN). Using a gene-targeted Hoxb1-GFP reporter in the mouse, we show that the LVN precursors originate exclusively from r4 and project to the spinal cord in the stereotypic pattern of the lateral vestibulospinal tract that provides input into spinal motoneurons driving extensor muscles of the limb. The r4-derived LVN precursors express the transcription factors Phox2a and Lbx1, and the glutamatergic marker Vglut2, which together defines them as dB2 neurons. Loss of Hoxb1 function does not alter the glutamatergic phenotype of dB2 neurons, but alters their stereotyped spinal cord projection. Moreover, at the expense of Phox2a, the glutamatergic determinants Lmx1b and Tlx3 were ectopically expressed by dB2 neurons. Our study suggests that the Hox genes determine the AP identity and diversity of vestibular precursors, including their output target, by coordinating the expression of neurotransmitter determinant and target selection properties along the AP axis.

The Sub-project W379, ''Spent Nuclear Fuel Canister Storage Building (CSB),'' was established as part of the Spent Nuclear Fuel (SNF) Project. The primary mission of the CSB is to safely store spent nuclear fuel removed from the K Basins in dry storage until such time that it can be transferred to the national geological repository at Yucca Mountain Nevada. This sub-project was initiated in late 1994 by a series of studies and conceptual designs. These studies determined that the partially constructed storage building, originally built as part of the Hanford Waste Vitrification Plant (HWVP) Project, could be redesigned to safely store the spent nuclear fuel. The scope of the CSB facility initially included a receiving station, a hot conditioning system, a storage vault, and a Multi-Canister Overpack (MCO) Handling Machine (MHM). Because of evolution of the project technical strategy, the hot conditioning system was deleted from the scope and MCO welding and sampling stations were added in its place. This report outlines the methods, procedures, and outputs developed by Project W379 to verify that the provided Structures, Systems, and Components (SSCs): satisfy the design requirements and acceptance criteria; perform their intended function; ensure that failure modes and hazards have been addressed in the design; and ensure that the SSCs as installed will not adversely impact other SSCs. The original version of this document was prepared by Vista Engineering for the SNF Project. Revision 1 documented verification actions that were pending at the time the initial report was prepared. Verification activities for the installed and operational SSCs have been completed. Verification of future additions to the CSB related to the canister cover cap and welding fixture system and MCO Internal Gas Sampling equipment will be completed as appropriate for those components. The open items related to verification of those requirements are noted in section 3

Projection methods for the calculation of incompressible or dilatable flows; Methodes de projection pour le calcul d'ecoulements incompressibles ou dilatables

Energy Technology Data Exchange (ETDEWEB)

Jobelin, M

2006-10-15

This thesis treats of time resolution methods for the Navier-Stokes equations. Based on the well-known projection method of Chorin and Temam, an original pressure correction method, named 'projection-penalty' is developed. Its specificity concerns the addition of a penalty term in the prediction step, which constrains the predicted velocity to fit with the mass balance. The precision improvements added by this method are demonstrated by some analysis results and by some numerical experiments of incompressible or dilatable flows. Finally, the potentialities offered by the use of the joint finite elements method in this type of fractionary step scheme is studied. Two applications are presented, one for local refinement purpose, the other for the resolution of a multi-physics problem. (J.S.)

This essay is a history and analysis of the steps leading to the origins of the space station partnership between the United States and its closest allies. It traces the process that led to the decision to invite other countries to participate in the project and their reasons for accepting that invitation. Not covered in this account are the difficult negotiations during the 1984-1988 period that led first to an initial set of agreements that allowed the prospective partners to work together during the early stages of the space station program and then to the final set of agreements creating the original space station partnership. Also, the 1993 invitation to the Russian Federation to join the original partners is not discussed, nor are the subsequent negotiations to revise the 1988 agreements.

This strategy finds its limits in the system's architecture. The CHADAC project proposes a simple and efficient solution to this problem, using a multiprocessor modular architecture. CHADAC main features are: parallel acquisition of data; CHADAC is fast, it dedicates one processor per branch and each processor can read and store one 16 bit word in 800 ns; original structure; each processor can work in its own private memory, in its own shared memory (double access) and in the shared memory of any other processor. Simple and fast communications between processors are also provided by local DMAs; flexibility; each processor is autonomous and may be used as an independent acquisition system for a branch, by connecting local peripherals to it. Adjunction of fast trigger logic is possible. By its architecture and performances, CHADAC is designed to provide a g...

Whitney, Richard P.; Berger, Matthew T.; Rushing, Samuel; Peone, Cory

2009-01-01

The Hellsgate Big Game Winter Range Wildlife Mitigation Project (Hellsgate Project) was proposed by the Confederated Tribes of the Colville Reservation (CTCR) as partial mitigation for hydropower's share of the wildlife losses resulting from Chief Joseph and Grand Coulee Dams. At present, the Hellsgate Project protects and manages 57,418 acres (approximately 90 miles2) for the biological requirements of managed wildlife species; most are located on or near the Columbia River (Lake Rufus Woods and Lake Roosevelt) and surrounded by Tribal land. To date we have acquired about 34,597 habitat units (HUs) towards a total 35,819 HUs lost from original inundation due to hydropower development. In addition to the remaining 1,237 HUs left unmitigated, 600 HUs from the Washington Department of Fish and Wildlife that were traded to the Colville Tribes and 10 secure nesting islands are also yet to be mitigated. This annual report for 2008 describes the management activities of the Hellsgate Big Game Winter Range Wildlife Mitigation Project (Hellsgate Project) during the past year.

Generalized projective synchronization via the state observer and its application in secure communication

International Nuclear Information System (INIS)

Wu Di; Li Juan-Juan

2010-01-01

Based on the improved state observer and the pole placement technique, by adding a constant which extends the scope of use of the original system, a new design method of generalized projective synchronization is proposed. With this method, by changing the projective synchronization scale factor, one can achieve not only complete synchronization, but also anti-synchronization, as well as arbitrary percentage of projective synchronization, so that the system may attain arbitrary synchronization in a relatively short period of time, which makes this study more meaningful. By numerical simulation, and choosing appropriate scale factor, the results of repeated experiments verify that this method is highly effective and satisfactory. Finally, based on this method and the relevant feedback concept, a novel secure communication project is designed. Numerical simulation verifies that this secure communication project is very valid, and moreover, the experimental result has been greatly improved in decryption time. (general)

Overview of work at the OECD/Nea data bank for the TDB project

Mompean, F.

2002-01-01

The NEA TDB Project aims at making available a comprehensive, internally consistent and quality-assured chemical thermodynamic database of selected chemical elements in order to meet the specialized modelling requirements for safety assessments of radioactive waste disposal systems. The project was initiated by the NEA in 1984 and reorganized in 1998. During the period 1984-1998 (TDB Project Phase I, TDB-I), reviews on the chemical thermodynamics for the following elements were completed: U, Am and Tc. A further review originating from TDB-I and dealing with data for Np and Pu appeared in print in May 2001. Although not strictly a part of TDB-I, a further collective publication of OECD/NEA [5] is a much-cited reference in the field of aquatic chemistry. The second phase of the TDB Project (TDB Project Phase II, TDB-II) was started in 1998 following an agreement between the following Participating Organisations. (author)

New Method of Selecting Efficient Project Portfolios in the Presence of Hybrid Uncertainty

Directory of Open Access Journals (Sweden)

Bogdan Rębiasz

2016-01-01

Full Text Available A new methods of selecting efficient project portfolios in the presence of hybrid uncertainty has been presented. Pareto optimal solutions have been defined by an algorithm for generating project portfolios. The method presented allows us to select efficient project portfolios taking into account statistical and economic dependencies between projects when some of the parameters used in the calculation of effectiveness can be expressed in the form of an interactive possibility distribution and some in the form of a probability distribution. The procedure for processing such hybrid data combines stochastic simulation with nonlinear programming. The interaction between data are modeled by correlation matrices and the interval regression. Economic dependences are taken into account by the equations balancing the production capacity of the company. The practical example presented indicates that an interaction between projects has a significant impact on the results of calculations. (original abstract

Network theory-based analysis of risk interactions in large engineering projects

International Nuclear Information System (INIS)

Fang, Chao; Marle, Franck; Zio, Enrico; Bocquet, Jean-Claude

2012-01-01

This paper presents an approach based on network theory to deal with risk interactions in large engineering projects. Indeed, such projects are exposed to numerous and interdependent risks of various nature, which makes their management more difficult. In this paper, a topological analysis based on network theory is presented, which aims at identifying key elements in the structure of interrelated risks potentially affecting a large engineering project. This analysis serves as a powerful complement to classical project risk analysis. Its originality lies in the application of some network theory indicators to the project risk management field. The construction of the risk network requires the involvement of the project manager and other team members assigned to the risk management process. Its interpretation improves their understanding of risks and their potential interactions. The outcomes of the analysis provide a support for decision-making regarding project risk management. An example of application to a real large engineering project is presented. The conclusion is that some new insights can be found about risks, about their interactions and about the global potential behavior of the project. - Highlights: ► The method addresses the modeling of complexity in project risk analysis. ► Network theory indicators enable other risks than classical criticality analysis to be highlighted. ► This topological analysis improves project manager's understanding of risks and risk interactions. ► This helps project manager to make decisions considering the position in the risk network. ► An application to a real tramway implementation project in a city is provided.

Guidance and Control Software Project Data - Volume 1: Planning Documents

Hayhurst, Kelly J. (Editor)

2008-01-01

The Guidance and Control Software (GCS) project was the last in a series of software reliability studies conducted at Langley Research Center between 1977 and 1994. The technical results of the GCS project were recorded after the experiment was completed. Some of the support documentation produced as part of the experiment, however, is serving an unexpected role far beyond its original project context. Some of the software used as part of the GCS project was developed to conform to the RTCA/DO-178B software standard, "Software Considerations in Airborne Systems and Equipment Certification," used in the civil aviation industry. That standard requires extensive documentation throughout the software development life cycle, including plans, software requirements, design and source code, verification cases and results, and configuration management and quality control data. The project documentation that includes this information is open for public scrutiny without the legal or safety implications associated with comparable data from an avionics manufacturer. This public availability has afforded an opportunity to use the GCS project documents for DO-178B training. This report provides a brief overview of the GCS project, describes the 4-volume set of documents and the role they are playing in training, and includes the planning documents from the GCS project. Volume 1 contains five appendices: A. Plan for Software Aspects of Certification for the Guidance and Control Software Project; B. Software Development Standards for the Guidance and Control Software Project; C. Software Verification Plan for the Guidance and Control Software Project; D. Software Configuration Management Plan for the Guidance and Control Software Project; and E. Software Quality Assurance Activities.

2007-12-01

Principles of constructivist educational philosophy serve as a foundation for the recently completed National Science Foundation sponsored undergraduate curricular revision undertaken by the Geology Department of Lake Superior State University. We integrate lecture and laboratory sessions utilizing active learning strategies that focus on real-world geoscience experiences and problems. In this presentation, we discuss details of three research-like projects that require students to access original data, process and model the data using appropriate geological software, interpret and defend results, and disseminate results in reports, posters, and class presentations. The projects are from three upper division courses, Carbonate Systems, Sequence Stratigraphy, and Geophysical Systems, where teams of two to four students are presented with defined problems of durations ranging from a few weeks to an entire semester. Project goals and location, some background information, and specified dates and expectations for interim and final written and oral reports are provided to students. Some projects require the entire class to work on one data set, some require each team to be initially responsible for a portion of the project with teams ultimately merging data for interpretation and to arrive at final conclusions. Some projects require students to utilize data from appropriate geological web sites such as state geological surveys. Others require students to design surveys and utilize appropriate instruments of their choice for field data collection. Students learn usage and applications of appropriate geological software in compiling, processing, modeling, and interpreting data and preparing formal reports and presentations. Students uniformly report heightened interest and motivation when engaged in these projects. Our new curriculum has resulted in an increase in students" quantitative and interpretive skills along with dramatic improvement in communication and

Performance of consultants on government projects in ghana: Client and contractor pespective

Directory of Open Access Journals (Sweden)

J. Dadzie

2013-07-01

Full Text Available Construction project consultants share the characteristics of helping their clients address problems and improve upon project performance; they have a passion for the wisdom and expertise they bring to the project, and they have the ability to galvanize clients into action. However, it is an open secret that many projects often delay. Also, it is a known fact that most project contract figures swell more than double the original tender figure. Meanwhile, there are supervising consultants who are engaged and paid to manage such important projects. Their role however, is to complement the effort of contractors to ensure a successful completion of a project. The aim of this research is to identify factors affecting the performance of consultants on government projects, and to rank these factors according to their relative importance from the perspective of consultants. Analysis of the factors considered in a survey indicate that the main factors negatively affecting the performance of consultants are: urgency of the project at hand, project duration, variations, political influence from higher authority, timely decision making on the part of the consulting team and the experience of the design team on the project. The others are the ability of the consultants to work as a team, creativity on the part of the consultants in controlling cost and developing own efficiencies so that contract sums are kept within budget .

The Commonwealth Local Government Pacific Project: Seeking ‘most significant change’

2010-03-01

Full Text Available The origins of the Commonwealth Local Government Forum’s Pacific Project date to a 1997 roundtable in Papua New Guinea. Substantial activity, however, commenced more recently in 2005 with the launch of a 5-year project to enhance the quality of local government in the small states of the Pacific Islands. The project was well-conceived and managed to establish strong ‘buy-in’ by major stakeholders and partners. A mid-term review was undertaken in 2008 and was generally positive. The project is now in the final stages of implementation of what it hoped will be only its first phase. In 2009-2010 its central task is to ensure that the ‘key results’ envisaged at the outset are achieved: donors are looking for evidence of real impact in participating countries; project administrators are refining management practices on the basis of the mid-term review (as well as the regular feedback they receive from participating countries; participating countries are being asked to realistically plan, and to better integrate project activities into their ongoing work-plans as evidence of both genuine development outcomes and future sustainability of lessons learned.

Stearns, Jeffrey A; Stearns, Marjorie A; Davis, Ardis K; Chessman, Alexander W

2007-01-01

In the original contract for the Family Medicine Curricular Resource Project (FMCRP), the Health Resources and Services Administration (HRSA), Division of Medicine and Dentistry, charged the FMCRP executive committee with reviewing recent medical education reform proposals and relevant recent curricula to develop an analytical framework for the project. The FMCRP executive and advisory committees engaged in a review and analysis of a variety of curricular reform proposals generated during the last decade of the 20th century. At the same time, in a separate and parallel process, representative individuals from all the family medicine organizations, all levels of learners, internal medicine and pediatric faculty, and the national associations of medical and osteopathic colleges (Association of American Medical Colleges and the American Association of Colleges of Osteopathic Medicine) were involved in group discussions to identify educational needs for physicians practicing in the 21st century. After deliberation, a theoretical framework was chosen for this undergraduate medical education resource that mirrors the Accreditation Council for Graduate Medical Education (ACGME) competencies, a conceptual design originated for graduate medical education. In addition to reflecting the current environment calling for change and greater accountability in medical education, use of the ACGME competencies as the theoretical framework for the FMCR provides a continuum of focus between the two major segments of physician education: medical school and residency.

The Waste Isolation Pilot Plant (WIPP) integrated project management system

International Nuclear Information System (INIS)

Olona, D.; Sala, D.

1993-01-01

The Waste Isolation Pilot Plant (WIPP), located 26 miles east of Carlsbad, New Mexico, is a research and development project of the Department of Energy (DOE), tasked with the mission of demonstrating the safe disposal of transuranic (TRU) radioactive wastes. This unique project was authorized by Congress in 1979 in response to the national need for long-term, safe methods for disposing of radioactive by-products from our national defense programs. The WIPP was originally established in December of 1979, by Public Law 96-164, DOE National Security and Military Applications of Nuclear Energy Authorization Act of 1980. Since the inception of the WIPP Project, work has continued to prepare the facility to receive TRU wastes. Studies continue to be conducted to demonstrate the safety of the WIPP facility in accordance with federal and state laws, state agreements, environmental regulations, and DOE Orders. The objectives of implementing an integrated project management system are to assure compliance with all regulatory and federal regulations, identify areas of concern, provide justification for funding, provide a management tool for control of program workscope, and establish a project baseline from which accountability and performance will be assessed. Program management and project controls are essential for the success of the WIPP Project. The WIPP has developed an integrated project management system to establish the process for the control of the program which has an expected total dollar value of $2B over the ten-year period from 1990-2000. The implementation of this project management system was motivated by the regulatory requirements of the project, the highly public environment in which the project takes place, limited funding and resources, and the dynamic nature of the project. Specific areas to be addressed in this paper include strategic planning, project organization, planning and scheduling, fiscal planning, and project monitoring and reporting

Full Text Available Our project is about the synthesis of a musical piece, based on the timeline of the Universe. We can understand music through visual and gestural analogies. In a similar way, popular descriptions of scientific concepts also use external metaphors and visual support to help comprehension. We will use music to describe a topic from astrophysics, the birth and evolution of the Universe. We describe the compositional technique used to create the composition 'Origin,' referring to recent techniques to derive music from tridimensional images and from gestures, under the light of the mathematical theory of music in the context of a narrative.

Factors that influence the outcome of information technology projects in South Africa: An empirical investigation

Directory of Open Access Journals (Sweden)

Carl Marnewick

2009-12-01

Full Text Available Purpose: In developing countries such as South Africa, many organisations are reliant on information and communication technology (ICT to provide accurate, relevant and timely information. For organisations to obtain and sustain a competitive advantage, ICT systems are constantly implemented, upgraded, modified or replaced. These initiatives are often managed as projects. While there is an increasing amount of both financial resources and effort being spent on ICT, these projects are not always delivered within the predetermined project constraints. This implies additional time to complete, as well as additional costs, as resources are not released in time to participate in other projects. It is therefore important to understand the factors that influence the outcome of South African ICT projects relative to their original constraints. Problem Investigated: The goal of this article is to determine the factors that influence South African ICT projects, taking into consideration the fact that most current published research on this topic was done within the context of a developed country such as the USA and Europe. Design and/or methodology: The outcomes of ICT projects in South Africa as well as the factors that influence them were determined through an extensive survey. An analysis was done on the factors together with a correlation between the main factors contributing to project outcomes. The purpose of this was to establish if a factor's presence or absence influenced the eventual outcome. Findings: The factors that contribute to a successful outcome are often outside the direct control of the project manager and tend to be complex in nature. One factor that does stand out is that the alignment of projects with business objectives influences their perceived success. Originality/Value: The benefits of this article are that it firstly provides a South African perspective of current ICT project management practices, and secondly, it highlights

Mediterranean Hydrogen Solar (MedHySol) is a federator project for development of a massive hydrogen production starting from solar energy and its exportation within a framework of a Euro-Maghrebian Cooperation project for industrial and energetic needs in the Mediterranean basin. The proposal of this project is included in the Algiers Declaration's on Hydrogen from Renewable Origin following the organization of the first international workshop on hydrogen which was held in 2005. Algeria is the privileged site to receive the MedHySol platform. The objective of the first step of the project is to realize a technological platform allowing the evaluation of emergent technologies of hydrogen production from solar energy with a significant size (10-100 kW) and to maintain the development of energetic rupture technologies. The second step of the project is to implement the most effective and less expensive technologies to pilot great projects (1-1000 MW). In this article we present the potentialities and the feasibility of MedHySol, as well as the fundamental elements for a scientific and technical supervision of this great project. (author)

Design of an electronic system with simultaneous registering of pulse amplitude and event time applied to the 4πβ-γ coincidence method

International Nuclear Information System (INIS)

Toledo, Fabio de

2009-01-01

The 4πβ-γ coincidence method for absolute radionuclide activity measurement has been considered for many years as a primary standard in Nuclear Metrology, because of dependence on few observable quantities and high accuracy. The Laboratorio de Metrologia Nuclear (LMN) - Nuclear Metrology Laboratory -, at Instituto de Pesquisas Energeticas e Nucleares (IPEN) - Nuclear and Energy Research Institute -, among its measurement techniques, uses the 4πβ-γ coincidence method. Recently a new technique known as 'software coincidence' has been used, with many advantages over the conventional coincidence methodology. In order to update the methodologies for radionuclide standardizations, the LMN developed a new system based on the software coincidence technique, described in the present work. This system uses the same nuclear set up for beta and gamma detection. The new software coincidence electronics uses a National Instruments (NI) acquisition card connected to a microcomputer and, through a connection panel, to the nuclear detection set up. The card configuration and controlling is accomplished by software using the LabVIEW, a NI proprietary product. This system records into disk files all the amplitudes and occurrence times for beta and gamma detected pulses. A suitable software was developed (the coincidence analysis program) to process the recorded data in order to obtain beta, gamma and coincidence counts and perform calculation of the radioactive source activity. The work also presents and discusses the results obtained with the first version of the coincidence analysis program, as well as perspectives for future works. (author)

The present study was conducted to evaluate the suitability of a repeated-dose liver micronucleus (LMN) assay in young adult rats as a collaborative study by the Mammalian mutagenicity study (MMS) group. All procedures were performed in accordance with the standard protocols of the MMS Group. Six-week-old male Crl:CD(SD) rats (5 animals/group) received oral doses of the hepatocarcinogen N-nitrosomorpholine (NMOR) at 0 (control), 5, 10, and 30mg/kg/day (10mL/kg) for 14 days. Control animals received vehicle (water). Hepatocytes were collected from the liver 24h after the last dose, and the number of micronucleated hepatocytes (MNHEPs) was determined by microscopy. The number of micronucleated immature erythrocytes (MNIMEs) in the femoral bone marrow was also determined. The liver was examined using histopathologic methods after formalin fixation. The results showed statistically significant and dose-dependent increases in the number of MNHEPs in the liver at doses of 10mg/kg and greater when compared with the vehicle control. However, no significant increase was noted in the number of MNIMEs in the bone marrow at doses of up to 30mg/kg. Histopathology of the liver revealed hypertrophy and single cell necrosis of hepatocytes at doses of 5mg/kg and above. These results showed that the induction of micronuclei by NMOR was detected by the repeated-dose LMN assay, but not by the repeated-dose bone marrow micronucleus assay. Copyright © 2014 Elsevier B.V.

2010-01-01

Full Text Available The detection of short optical transients of astrophysical origin in real time is an important task for existing robotic telescopes. The faster a new optical transient is detected, the earlier follow-up observations can be started. The sooner the object is identified, the more data can be collected before the source fades away, particularly in the most interesting early period of the transient. In this the real-time pipeline designed for identification of optical flashes with the “Pi of the Sky” project will be presented in detail together with solutions used by other experiments.

Full Text Available Jacques Derrida developed deconstruction as a way of thinking which constantly examines the nature and possibilities of meaning. The paper analyses spatial-economic, cultural and social context in which deconstructive discourse was translated into architectural discourse. Translation between these two discourses happens vice versa. Deconstructivism emphasizes the formal properties of architecture, like postmodernism, which is the subject of exploration by architects such as Coop Himmelblau, Frank Gehry, Eric Owen Moss, etc. According to some interpretations, the only solution for deconstruction in architectural work is incompleteness, an open project which represents never-ending deconstruction. There are different solutions for open projects, and the article highlights projects by architects mentioned above, which seems to manage to achieve continuous deconstruction in practice.   Article received: December 23, 2016; Article accepted: January 18, 2017; Published online: April 20, 2017 Original scholarly paper How to cite this paper: Tošić, Jovana.

2006-01-01

A study was sponsored by FEMP in 2001 - 2002 to develop methods to compare life-cycle costs of federal energy conservation projects carried out through energy savings performance contracts (ESPCs) and projects that are directly funded by appropriations. The study described in this report follows up on the original work, taking advantage of new pricing data on equipment and on $500 million worth of Super ESPC projects awarded since the end of FY 2001. The methods developed to compare life-cycle costs of ESPCs and directly funded energy projects are based on the following tasks: (1) Verify the parity of equipment prices in ESPC vs. directly funded projects; (2) Develop a representative energy conservation project; (3) Determine representative cycle times for both ESPCs and appropriations-funded projects; (4) Model the representative energy project implemented through an ESPC and through appropriations funding; and (5) Calculate the life-cycle costs for each project.

Classification of heterogeneous electron microscopic projections into homogeneous subsets

2008-01-01

The co-existence of different states of a macromolecular complex in samples used by three-dimensional electron microscopy (3D-EM) constitutes a serious challenge. The single particle method applied directly to such heterogeneous sets is unable to provide useful information about the encountered conformational diversity and produces reconstructions with severely reduced resolution. One approach to solving this problem is to partition heterogeneous projection set into homogeneous components and apply existing reconstruction techniques to each of them. Due to the nature of the projection images and the high noise level present in them, this classification task is difficult. A method is presented to achieve the desired classification by using a novel image similarity measure and solving the corresponding optimization problem. Unlike the majority of competing approaches, the presented method employs unsupervised classification (it does not require any prior knowledge about the objects being classified) and does not involve a 3D reconstruction procedure. We demonstrate a fast implementation of this method, capable of classifying projection sets that originate from 3D-EM. The method's performance is evaluated on synthetically generated data sets produced by projecting 3D objects that resemble biological structures

Group-Effort Applied Research (GEAR): Expanding Opportunities for Undergraduate Research Through Original, Class-Based Research Projects

Moore, Sean D.; Teter, Ken

2014-01-01

Undergraduate research clearly enriches the educational development of participating students, but these experiences are limited by the inherent inefficiency of the standard one student - one mentor model for undergraduate research. Group-Effort Applied Research (GEAR) was developed as a strategy to provide substantial numbers of undergraduates with meaningful research experiences. The GEAR curriculum delivers concept-driven lecture material and provides hands-on training in the context of an active research project from the instructor's lab. Because GEAR is structured as a class, participating students benefit from intensive, supervised research training that involves a built-in network of peer support and abundant contact with faculty mentors. The class format also ensures a relatively standardized and consistent research experience. Furthermore, meaningful progress toward a research objective can be achieved more readily with GEAR than with the traditional one student - one mentor model of undergraduate research because sporadic mistakes by individuals in the class are overshadowed by the successes of the group as a whole. Three separate GEAR classes involving three distinct research projects have been offered to date. In this paper, we provide an overview of the GEAR format and review some of the recurring themes for GEAR instruction. We propose GEAR can serve as a template to expand student opportunities for life science research without sacrificing the quality of the mentored research experience. PMID:24898007

Mapping replication origins in yeast chromosomes.

Science.gov (United States)

Brewer, B J; Fangman, W L

1991-07-01

The replicon hypothesis, first proposed in 1963 by Jacob and Brenner, states that DNA replication is controlled at sites called origins. Replication origins have been well studied in prokaryotes. However, the study of eukaryotic chromosomal origins has lagged behind, because until recently there has been no method for reliably determining the identity and location of origins from eukaryotic chromosomes. Here, we review a technique we developed with the yeast Saccharomyces cerevisiae that allows both the mapping of replication origins and an assessment of their activity. Two-dimensional agarose gel electrophoresis and Southern hybridization with total genomic DNA are used to determine whether a particular restriction fragment acquires the branched structure diagnostic of replication initiation. The technique has been used to localize origins in yeast chromosomes and assess their initiation efficiency. In some cases, origin activation is dependent upon the surrounding context. The technique is also being applied to a variety of eukaryotic organisms.

Hoxb1 controls anteroposterior identity of vestibular projection neurons.

Directory of Open Access Journals (Sweden)

Yiju Chen

Full Text Available The vestibular nuclear complex (VNC consists of a collection of sensory relay nuclei that integrates and relays information essential for coordination of eye movements, balance, and posture. Spanning the majority of the hindbrain alar plate, the rhombomere (r origin and projection pattern of the VNC have been characterized in descriptive works using neuroanatomical tracing. However, neither the molecular identity nor developmental regulation of individual nucleus of the VNC has been determined. To begin to address this issue, we found that Hoxb1 is required for the anterior-posterior (AP identity of precursors that contribute to the lateral vestibular nucleus (LVN. Using a gene-targeted Hoxb1-GFP reporter in the mouse, we show that the LVN precursors originate exclusively from r4 and project to the spinal cord in the stereotypic pattern of the lateral vestibulospinal tract that provides input into spinal motoneurons driving extensor muscles of the limb. The r4-derived LVN precursors express the transcription factors Phox2a and Lbx1, and the glutamatergic marker Vglut2, which together defines them as dB2 neurons. Loss of Hoxb1 function does not alter the glutamatergic phenotype of dB2 neurons, but alters their stereotyped spinal cord projection. Moreover, at the expense of Phox2a, the glutamatergic determinants Lmx1b and Tlx3 were ectopically expressed by dB2 neurons. Our study suggests that the Hox genes determine the AP identity and diversity of vestibular precursors, including their output target, by coordinating the expression of neurotransmitter determinant and target selection properties along the AP axis.

Applying EVM principles to Tevatron Beam Position Monitor Project

International Nuclear Information System (INIS)

Banerjee, Bakul

2005-01-01

At Fermi National Accelerator Laboratory (Fermilab), the Tevatron high energy particle collider must meet the increasing scientific demand of higher beam luminosity. To achieve this higher luminosity goal, U. S. Department of Energy (DOE) sponsored a major upgrade of capabilities of Fermilab's accelerator complex that spans five years and costs over fifty million dollars. Tevatron Beam Position Monitor (BPM) system upgrade is a part of this project, generally called RunII upgrade project. Since the purpose of the Tevatron collider is to detect the smashing of proton and anti-protons orbiting the circular accelerator in opposite directions, capability to detect positions of both protons and antiprotons at a high resolution level is a desirable functionality of the monitoring system. The original system was installed during early 1980s, along with the original construction of the Tevatron. However, electronic technology available in 1980s did not allow for the detection of significantly smaller resolution of antiprotons. The objective of the upgrade project is to replace the existing BPM system with a new system utilizing capabilities of modern electronics enhanced by a front-end software driven by a real-time operating software. The new BPM system is designed to detect both protons and antiprotons with increased resolution of up to an order of magnitude. The new system is capable of maintaining a very high-level of data integrity and system reliability. The system consists of 27 VME crates installed at 27 service buildings around the Tevatron ring servicing 236 beam position monitors placed underground, inside the accelerator tunnel. Each crate consists of a single Timing Generator Fanout module, custom made by Fermilab staff, one MVME processor card running VxWorks 5.5, multiple Echotek Digital Receiver boards complimented by custom made Filter Board. The VxWorks based front-end software communicates with the Main Accelerator Control software via a special

World in Mercator Projection, Shaded Relief and Colored Height

Science.gov (United States)

2003-01-01

This image of the world was generated with data from the Shuttle Radar Topography Mission (SRTM). The SRTM Project has recently released a new global data set called SRTM30, where the original one arcsecond of latitude and longitude resolution (about 30 meters, or 98 feet, at the equator) was reduced to 30 arcseconds (about 928 meters, or 1496 feet.) This image was created from that data set and shows the world between 60 degrees south and 60 degrees north latitude, covering 80% of the Earth's land mass. The image is in the Mercator Projection commonly used for maps of the world.Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations.Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise,Washington, D.C.Orientation: North toward the top, Mercator projection Image Data: shaded and colored SRTM

In 1984 the Ontario Geological Survey initiated a research project on the Sudbury structure (SS) in cooperation with the University of Muenster. The project included field mapping (1984-1989) and petrographic, chemical, and isotope analyses of the major stratigraphic units of the SS. Four diploma theses and four doctoral theses were performed during the project (1984-1992). Specific results of the various investigations are reported. Selected areas of the SS were mapped and sampled: Footwall rocks; Footwall breccia and parts of the sublayer and lower section of the Sudbury Igneous Complex (SIC); Onaping Formation and the upper section of the SIC; and Sudbury breccia and adjacent Footwall rocks along extended profiles up to 55 km from the SIC. All these stratigraphic units of the SS were studied in substantial detail by previous workers. The most important characteristic of the previous research is that it was based either on a volcanic model or on a mixed volcanic-impact model for the origin of the SS. The present project was clearly directed toward a test of the impact origin of the SS without invoking an endogenic component. In general, our results confirm the most widely accepted stratigraphic division of the SS. However, our interpretation of some of the major stratigraphic units is different from most views expressed. The stratigraphy of the SS and its new interpretation is given as a basis for discussion.

Parent-of-origin effect in multiple sclerosis: observations from interracial matings.

Multiple sclerosis (MS) is a complex neurologic disease with a striking geographical distribution. In Canada, prevalence is high in Caucasians of Northern European ancestry and uncommon in North American Aboriginals, many of whom now have Caucasian admixture. The population-based Canadian Collaborative Project on the Genetic Susceptibility to MS provided the characteristics of 58 individuals with 1 Caucasian and 1 North American Aboriginal parent from a database of 30,000 MS index cases. We found that MS index cases with a Caucasian mother and a North American Aboriginal father had a higher sib recurrence risk and greater F:M sex ratio (p = 0.043) than patients with a North American Aboriginal mother and Caucasian father. Maternal parent-of-origin effects in multiple sclerosis disease etiology previously seen in studies of half-siblings and avuncular pairs are also seen in Caucasian-North American Aboriginal admixture matings and warrant further investigation. A differential influence of maternal risk transmission on the sex ratio of affected offspring is implied. The method of analysis used may have broader implications for detection of parent-of-origin effects in admixture cohorts.

Geography and genography: prediction of continental origin using randomly selected single nucleotide polymorphisms

Directory of Open Access Journals (Sweden)

Ramoni Marco F

2007-03-01

Full Text Available Abstract Background Recent studies have shown that when individuals are grouped on the basis of genetic similarity, group membership corresponds closely to continental origin. There has been considerable debate about the implications of these findings in the context of larger debates about race and the extent of genetic variation between groups. Some have argued that clustering according to continental origin demonstrates the existence of significant genetic differences between groups and that these differences may have important implications for differences in health and disease. Others argue that clustering according to continental origin requires the use of large amounts of genetic data or specifically chosen markers and is indicative only of very subtle genetic differences that are unlikely to have biomedical significance. Results We used small numbers of randomly selected single nucleotide polymorphisms (SNPs from the International HapMap Project to train naïve Bayes classifiers for prediction of ancestral continent of origin. Predictive accuracy was tested on two independent data sets. Genetically similar groups should be difficult to distinguish, especially if only a small number of genetic markers are used. The genetic differences between continentally defined groups are sufficiently large that one can accurately predict ancestral continent of origin using only a minute, randomly selected fraction of the genetic variation present in the human genome. Genotype data from only 50 random SNPs was sufficient to predict ancestral continent of origin in our primary test data set with an average accuracy of 95%. Genetic variations informative about ancestry were common and widely distributed throughout the genome. Conclusion Accurate characterization of ancestry is possible using small numbers of randomly selected SNPs. The results presented here show how investigators conducting genetic association studies can use small numbers of arbitrarily

A telencephalospinal projection in the Tegu lizard (Tupinambis teguixin).

Science.gov (United States)

Follett, K A

1989-09-04

Tegu lizards (Tupinambis teguixin) were studied to determine the presence of a homologue of the mammalian corticospinal tract. The sources of telencephalic efferent projections to the spinal cord were determined by evaluating the localization of retrogradely transported horseradish peroxidase applied in the cervical spinal cord. Labeled cells were present in subtelencephalic sites reported previously by other authors and, in addition, were found in the principal sensory and motor nuclei of the trigeminal nerve and in the nucleus of the posterior commissure. A telencephalospinal projection was identified, originating in the ventral caudal telencephalon. Histochemical staining revealed a high concentration of acetylcholinesterase in cells and neuropil in the same area. This tract is suggested to be homologous to the mammalian amygdalospinal tract. No reptilian homologue of the corticospinal tract was identified.

Afferent projections to the deep mesencephalic nucleus in the rat

International Nuclear Information System (INIS)

Veazey, R.B.; Severin, C.M.

1982-01-01

Afferent projections to the deep mesencephalic nucleus (DMN) of the rat were demonstrated with axonal transport techniques. Potential sources for projections to the DMN were first identified by injecting the nucleus with HRP and examining the cervical spinal cord, brain stem, and cortex for retrogradely labeled neurons. Areas consistently labeled were then injected with a tritiated radioisotope, the tissue processed for autoradiography, and the DMN examined for anterograde labeling. Afferent projections to the medial and/or lateral parts of the DMN were found to originate from a number of spinal, bulbar, and cortical centers. Rostral brain centers projecting to both medial and lateral parts of the DMN include the ipsilateral motor and somatosensory cortex, the entopeduncular nucleus, and zona incerta. at the level of the midbrain, the ipsilateral substantia nigra and contralateral DMN likewise project to the DMN. Furthermore, the ipsilateral superior colliculus projects to the DMN, involving mainly the lateral part of the nucleus. Afferents from caudal centers include bilateral projections from the sensory nucleus of the trigeminal complex and the nucleus medulla oblongata centralis, as well as from the contralateral dentate nucleus. The projections from the trigeminal complex and nucleus medullae oblongatae centralis terminate in the intermediate and medial parts of the DMN, whereas projections from the contralateral dentate nucleus terminate mainly in its lateral part. In general, the afferent connections of the DMN arise from diverse areas of the brain. Although most of these projections distribute throughout the entire extent of the DMN, some of them project mainly to either medial or lateral parts of the nucleus, thus suggesting that the organization of the DMN is comparable, at least in part, to that of the reticular formation of the pons and medulla, a region in which hodological differences between medial and lateral subdivisions are known to exist

The future GNSS Galileo system offer a number of benefits (e.g. availability of better accuracy positioning, new frequencies bands allowing the implementation of specific techniques, provable time-stamp and location data using SIS authorisation, integrity, better support ad-hoc algorithms for data analysis and other service guarantee for liability and regulated applications) are widely spread among different disciplines. Also applications which are less interesting from the commercial and market point of view could successfully contribute to the numerous social benefits and support the innovation in the international research. The aim of the GEO-6 project "Scientific research Using GNSS" is to propose and broaden scientific utilization of future GNSS Galileo system data in research. It is a joint project of seven institutions from six countries led by the Atos Origin Company from Spain. The core of the project consists from six projects in five priority areas: PA-1 Remote sensing of the ocean using GNSS reflections, PA-2a Investigating GNSS ionospheric data assimilation, PA-2b 3-D gravity wave detection and determination (both PA-2a and PA-2b are ionospheric topics), PA-3 Demonstration of capability for operational forecasting of atmospheric delays, PA-4 GNSS seismometer, PA-5 Spacecraft formation flying using global navigation satellite systems. Institute of Atmospheric Physics, Prague, Czech Republic is responsible for the project PA-2b, where we developed and tested (to the extent allowed by available data) an algorithm and computer code for the 3-D detection of gravity waves and determination of their characteristics. The main drivers of the GEO-6 project are: high levels of accuracy even with the support of local elements, sharing of solutions and results for the worldwide scientific community. The paper will present basic description of the project with more details concerning Czech participation in it.

Full Text Available Purpose: This study aims to review the implementation of the Lean Six Sigma project methodology in the Johnson Space Center (JSC business environment of National Aeronautics and Space Administration (NASA with an objective of evaluating performance of individual projects and to develop recommendation for strategies to improve operational efficiencies based on Data Envelopment Analysis (DEA.Design/methodology/approach: In this study, authors propose the Lean Six Sigma project performance evaluation model (LSS-PPEM based on Data DEA where Critical Success Factors (CSFs and Total Team Hours serve as inputs while Process Sigma and Cost avoidance are used as outputs. The CSFs are factors that critically affect the performance of LSS at JSC. Six of those are identified by the Black Belts through Analytical Hierarchical Process, and the values of those are decided by project leaders and Green Belts through survey. Eighteen LSS projects are evaluated, and their results are analyzed.Findings and Originality/value: Eventually, four out of the six CSFs are adopted for this study based upon Pearson correlation analysis, and those four include Project execution and follow up of results; Top management’s commitment and participation; The use of data analysis with easily obtainable data; Attention given to both long and short term targets. Using data between the years 2009 and 2011, seven of the eighteen projects are found to be efficient.

One project`s waste is another project`s resource

Energy Technology Data Exchange (ETDEWEB)

Short, J.

1997-02-01

The author describes the efforts being made toward pollution prevention within the DOE complex, as a way to reduce overall project costs, in addition to decreasing the amount of waste to be handled. Pollution prevention is a concept which is trying to be ingrained into project planning. Part of the program involves the concept that ultimately the responsibility for waste comes back to the generator. Parts of the program involve efforts to reuse materials and equipment on new projects, to recycle wastes to generate offsetting revenue, and to increase awareness, accountability and incentives so as to stimulate action on this plan. Summaries of examples are presented in tables.

The marine environment offers both economic and scientific potential which are relatively untapped from a biotechnological point of view. These environments whilst harsh are ironically fragile and dependent on a harmonious life form balance. Exploitation of natural resources by exhaustive wild harvesting has obvious negative environmental consequences. From a European industry perspective marine organisms are a largely underutilised resource. This is not due to lack of interest but due to a lack of choice the industry faces for cost competitive, sustainable and environmentally conscientious product alternatives. Knowledge of the biotechnological potential of marine organisms together with the development of sustainable systems for their cultivation, processing and utilisation are essential. In 2010, the European Commission recognised this need and funded a collaborative RTD/SME project under the Framework 7-Knowledge Based Bio-Economy (KBBE) Theme 2 Programme 'Sustainable culture of marine microorganisms, algae and/or invertebrates for high value added products'. The scope of that project entitled 'Sustainable Production of Biologically Active Molecules of Marine Based Origin' (BAMMBO) is outlined. Although the Union is a global leader in many technologies, it faces increasing competition from traditional rivals and emerging economies alike and must therefore improve its innovation performance. For this reason innovation is placed at the heart of a European Horizon 2020 Strategy wherein the challenge is to connect economic performance to eco performance. This article provides a synopsis of the research activities of the BAMMBO project as they fit within the wider scope of sustainable environmentally conscientious marine resource exploitation for high-value biomolecules.

Guidance and Control Software Project Data - Volume 3: Verification Documents

Science.gov (United States)

Hayhurst, Kelly J. (Editor)

2008-01-01

The Guidance and Control Software (GCS) project was the last in a series of software reliability studies conducted at Langley Research Center between 1977 and 1994. The technical results of the GCS project were recorded after the experiment was completed. Some of the support documentation produced as part of the experiment, however, is serving an unexpected role far beyond its original project context. Some of the software used as part of the GCS project was developed to conform to the RTCA/DO-178B software standard, "Software Considerations in Airborne Systems and Equipment Certification," used in the civil aviation industry. That standard requires extensive documentation throughout the software development life cycle, including plans, software requirements, design and source code, verification cases and results, and configuration management and quality control data. The project documentation that includes this information is open for public scrutiny without the legal or safety implications associated with comparable data from an avionics manufacturer. This public availability has afforded an opportunity to use the GCS project documents for DO-178B training. This report provides a brief overview of the GCS project, describes the 4-volume set of documents and the role they are playing in training, and includes the verification documents from the GCS project. Volume 3 contains four appendices: A. Software Verification Cases and Procedures for the Guidance and Control Software Project; B. Software Verification Results for the Pluto Implementation of the Guidance and Control Software; C. Review Records for the Pluto Implementation of the Guidance and Control Software; and D. Test Results Logs for the Pluto Implementation of the Guidance and Control Software.

1994-01-01

To make a plan for a project is one thing; to control it are a hundred things at the same time. Because of this fact, the enterprises and Research and Development Institutions have searched better ways to manage this activities. The management system of Research and Development projects and services from ININ, is used as a recording, evaluation tracking, information and control of result instrument for these activities. The need to have update information of different activities in the working areas of ININ, such as: Projects, technical or technological services either internal or external; diffusion programs and human resources training programs; and departmental activities, has taken to the development of uniform methods of recording, evaluation tracking and control of events, which allow the standardization, compilation, analysis and reporting of the results in an easy and quick way. The elaboration of an original scheme for the evaluation system of assessment for Research and Development projects and services was started in July 1988, and the data acquisition was manual. The use of Personal Computers began at 1992. (Author)

This report summarizes the accomplishments of the project ''Studies of nuclear reactions at very low energies''. This project was undertaken in 1987 and completed in 1993. All but one of the major objectives of this study have been accomplished. Specifically the authors have completed their investigation of the (p,γ) on light nuclei, a study of the Oppenheimer-Phillips effect, a measurements of the astrophysically interesting reaction D(α,γ) 6 Li at low energies and an extension of the reaction D(d,γ) 4 He to lower energies than previously observed. Preliminary investigation of te reaction 7 Li( 3 He,p) 9 Be was begun and is continuing under a separate DOE grant. In addition to these tasks, they have completed some very interesting projects which were not included in the original proposal. These include a study of the (d,γ) reactions on 6 Li, 7 Li and 10 B and an investigation of the possibility of observing terrestrial antineutrinos from the beta decay chains of U and Th as a diagnostic of terrestrial heat flow

A Principal Component Analysis of Project Management Construction Industry Competencies for the Ghanaian

Directory of Open Access Journals (Sweden)

Rockson Dobgegah

2011-03-01

Full Text Available The study adopts a data reduction technique to examine the presence of any complex structure among a set of project management competency variables. A structured survey questionnaire was administered to 100 project managers to elicit relevant data, and this achieved a relatively high response rate of 54%. After satisfying all the necessary tests of reliability of the survey instrument, sample size adequacy and population matrix, the data was subjected to principal component analysis, resulting in the identification of six new thematic project management competency areas ; and were explained in terms of human resource management and project control; construction innovation and communication; project financial resources management; project risk and quality management; business ethics and; physical resources and procurement management. These knowledge areas now form the basis for lateral project management training requirements in the context of the Ghanaian construction industry. Key contribution of the paper is manifested in the use of the principal component analysis, which has rigorously provided understanding into the complex structure and the relationship between the various knowledge areas. The originality and value of the paper is embedded in the use of contextual-task conceptual knowledge to expound the six uncorrelated empirical utility of the project management competencies.

1999-01-01

The US Nuclear Regulatory Commission (NRC) is prescribing decontamination and decommissioning (cleanup) criteria for the West Valley Demonstration Project and the West Valley, New York, site. The site is contaminated with various forms of residual radioactive contamination and contains a wide variety of radioactive waste. The NRC is planning to issue cleanup criteria for public comment in Fall 1999. Due to the complexity of the site, and the newness of NRC's cleanup criteria policy, applying NRC's cleanup criteria to this site will be an original regulatory undertaking. (author)

Distribution and origin of authigenic smectite clays in Cape Roberts Project Core 3, Victoria Land Basin, Antarctica

Science.gov (United States)

Priestas, A.W.; Wise, S.W.

2007-01-01

Of some 800 m of lower Oligocene marine sediments cored continuously from the seafloor in the Victoria Land Basin of Antarctica at Cape Roberts Site CRP-3, the lower 500 m exhibit authigenic smectite clay coats on shallow-water sandstone grains. A scanning electron microscope/EDS study of 46 fracture sections confirms that the distribution of the clay coats through the unit is not uniform or evenly distributed, but rather varies with depth, original porosity, and the kinds and abundance of source materials. Our results suggest that smectite emplacement resulted from in-situ, low-temperature burial diagenesis rather than hydrothermal or fault-focused thermobaric fluids.

We describe efforts to identify novel genes and hosts for the generation of an optimal biocatalyst, analysis of diesel fuels (untreated, chemically oxidized and hydrotreated) for organosulfur compound composition and directed evolution of enzymes central to the biodesulfurization pathway to optimize properties important for their use in a biocatalyst. Finally we will summarize the challenges and issues that are central to successful development of a viable biodesulfurization process.

End user orientation of TC projects. Special evaluation review

International Nuclear Information System (INIS)

1996-12-01

The present review of the end use orientation of TC projects was undertaken as requested by the TC Department to identify: (a) end users and beneficiaries beyond the boundaries of the counterpart laboratories, as appropriate; (b) means provided or planned to reach the end users and beneficiaries; (c) performance indicators in quantifiable terms, including those related to the counterpart activities that could be foreseen during and after completion of Agency assistance; and (d) recommendations of additional means, if necessary, to reach the end users and beneficiaries. A total of 13 TC projects with large budgets of around $200,000 and above were selected from those first approved under the 1995-1996 biennial programme and supported under the TCF, representing diverse fields of Agency activities and covering all the geographical areas of the Agency's technical co-operation. The projects thus selected were one each from Argentina, Bolivia, Bulgaria, Chile, Colombia, Egypt, Ethiopia, Jordan, Mexico, Mongolia, Slovenia, Turkey and Viet-Nam. The overall budget of the 13 projects as originally approved for 1995 to 1998, amounted to $5,510,980. The current budget as of 8 November 1996 stands at $5,446,719, representing a decrease of more than one percent. Figs, tabs

Projective limits of state spaces IV. Fractal label sets

Science.gov (United States)

Lanéry, Suzanne; Thiemann, Thomas

2018-01-01

Instead of formulating the state space of a quantum field theory over one big Hilbert space, it has been proposed by Kijowski (1977) to represent quantum states as projective families of density matrices over a collection of smaller, simpler Hilbert spaces (see Lanéry (2016) [1] for a concise introduction to this formalism). One can thus bypass the need to select a vacuum state for the theory, and still be provided with an explicit and constructive description of the quantum state space, at least as long as the label set indexing the projective structure is countable. Because uncountable label sets are much less practical in this context, we develop in the present article a general procedure to trim an originally uncountable label set down to countable cardinality. In particular, we investigate how to perform this tightening of the label set in a way that preserves both the physical content of the algebra of observables and its symmetries. This work is notably motivated by applications to the holonomy-flux algebra underlying Loop Quantum Gravity. Building on earlier work by Okołów (2013), a projective state space was introduced for this algebra in Lanéry and Thiemann (2016). However, the non-trivial structure of the holonomy-flux algebra prevents the construction of satisfactory semi-classical states (Lanéry and Thiemann, 2017). Implementing the general procedure just mentioned in the case of a one-dimensional version of this algebra, we show how a discrete subalgebra can be extracted without destroying universality nor diffeomorphism invariance. On this subalgebra, quantum states can then be constructed which are more regular than was possible on the original algebra. In particular, this allows the design of semi-classical states whose semi-classicality is enforced step by step, starting from collective, macroscopic degrees of freedom and going down progressively toward smaller and smaller scales.

MODELS AND METHODS OF SAFETY-ORIENTED PROJECT MANAGEMENT OF DEVELOPMENT OF COMPLEX SYSTEMS: METHODOLOGICAL APPROACH

Directory of Open Access Journals (Sweden)

Олег Богданович ЗАЧКО

2016-03-01

Full Text Available The methods and models of safety-oriented project management of the development of complex systems are proposed resulting from the convergence of existing approaches in project management in contrast to the mechanism of value-oriented management. A cognitive model of safety oriented project management of the development of complex systems is developed, which provides a synergistic effect that is to move the system from the original (pre condition in an optimal one from the viewpoint of life safety - post-project state. The approach of assessment the project complexity is proposed, which consists in taking into account the seasonal component of a time characteristic of life cycles of complex organizational and technical systems with occupancy. This enabled to take into account the seasonal component in simulation models of life cycle of the product operation in complex organizational and technical system, modeling the critical points of operation of systems with occupancy, which forms a new methodology for safety-oriented management of projects, programs and portfolios of projects with the formalization of the elements of complexity.

Coating of pumps is a quite new activity. For many years pipes and containers have been coated inside in order to avoid corrosion, but the technology has only been used inside pumps for the last ten years. The technology comes from USA and is originally developed in the space technology industry as an exceptionally durable and corrosion constant coating. The project is a further development of results found in a previous R and D project in which measurements were performed before and after coating two different installations. Both installations showed large efficiency improvements. This project supplements the theory behind losses in pumps with measurements on more pumps. (BA)

Final Technical Report - Modernization of the Boulder Canyon Hydroelectric Project

Energy Technology Data Exchange (ETDEWEB)

Taddeucci, Joe [Dept. of Public Works, Boulder, CO (United States). Utilities Division

2013-03-29

The Boulder Canyon Hydroelectric Project (BCH) was purchased by the City of Boulder, CO (the city) in 2001. Project facilities were originally constructed in 1910 and upgraded in the 1930s and 1940s. By 2009, the two 10 MW turbine/generators had reached or were nearing the end of their useful lives. One generator had grounded out and was beyond repair, reducing plant capacity to 10 MW. The remaining 10 MW unit was expected to fail at any time. When the BCH power plant was originally constructed, a sizeable water supply was available for the sole purpose of hydroelectric power generation. Between 1950 and 2001, that water supply had gradually been converted to municipal water supply by the city. By 2001, the water available for hydroelectric power generation at BCH could not support even one 10 MW unit. Boulder lacked the financial resources to modernize the facilities, and Boulder anticipated that when the single, operational historical unit failed, the project would cease operation. In 2009, the City of Boulder applied for and received a U.S. Department of Energy (DOE) grant for $1.18 million toward a total estimated project cost of $5.155 million to modernize BCH. The federal funding allowed Boulder to move forward with plant modifications that would ensure BCH would continue operation. Federal funding was made available through the American Recovery and Reinvestment Act (ARRA) of 2009. Boulder determined that a single 5 MW turbine/generator would be the most appropriate capacity, given the reduced water supply to the plant. Average annual BCH generation with the old 10 MW unit had been about 8,500 MW-hr, whereas annual generation with a new, efficient turbine could average 11,000 to 12,000 MW-hr. The incremental change in annual generation represents a 30% increase in generation over pre-project conditions. The old turbine/generator was a single nozzle Pelton turbine with a 5-to-1 flow turndown and a maximum turbine/generator efficiency of 82%. The new unit is a

Best practices for preparing vessel internals segmentation projects

International Nuclear Information System (INIS)

Boucau, Joseph; Segerud, Per; Sanchez, Moises

2016-01-01

Westinghouse has been involved in reactor internals segmentation activities in the U.S. and Europe for 30 years. Westinghouse completed in 2015 the segmentation of the reactor vessel and reactor vessel internals at the Jose Cabrera nuclear power plant in Spain and a similar project is on-going at Chooz A in France. For all reactor dismantling projects, it is essential that all activities are thoroughly planned and discussed up-front together with the customer. Detailed planning is crucial for achieving a successful project. One key activity in the preparation phase is the 'Segmentation and Packaging Plan' that documents the sequential steps required to segment, separate, and package each individual component, based on an activation analysis and component characterization study. Detailed procedures and specialized rigging equipment have to be developed to provide safeguards for preventing certain identified risks. The preparatory work can include some plant civil structure modifications for making the segmentation work easier and safer. Some original plant equipment is sometimes not suitable enough and need to be replaced. Before going to the site, testing and qualification are performed on full scale mock-ups in a specially designed pool for segmentation purposes. The mockup testing is an important step in order to verify the function of the equipment and minimize risk on site. This paper is describing the typical activities needed for preparing the reactor internals segmentation activities using under water mechanical cutting techniques. It provides experiences and lessons learned that Westinghouse has collected from its recent projects and that will be applied for the new awarded projects. (authors)

U.S. China Carbon Capture and Storage Development Project at West Virginia University

Energy Technology Data Exchange (ETDEWEB)

Fletcher, Jerald

2013-12-31

The original overall objective of this activity was to undertake resource evaluation and planning for CCS projects and to describe and quantify the geologic, environmental, and economic challenges to successful development of large-scale CCS in China’s coal sector. Several project execution barriers were encountered in the course of this project, most notably a project stop/delay due to funds availability/costing restrictions from the US State Department to the US Department of Energy at the end of CY2012, which halted project execution from January 2, 2013 to April 1, 2013. At the resolution of this project delay, it was communicated to the project team that the overall project period would also be reduced, from a completion date of February 28, 2014 to December 31, 2013. The net impact of all these changes was a reduction in the project period from 24 months (3/1/2012-2/28/2014) to 22 months (3/1/2012-12/31/2013), with a 3 month stop from 1/1/2013-3/31/2013. The project team endeavored to overcome these project time impacts, focusing heavily on technoeconomic modeling that would be deliverable under Task 3 (Ordos Basin Feasibility Study), and choosing to abandon the full investigation into the Demonstration Site (Task 4) due to the reduced project time. The ultimate focus of this project changed to work with the Chinese on a carbon atlas/geologic characterization, and on mechanisms for CO2 storage options from high-quality streams within China.

From a CEU '98er: 9 years and 5 research projects later

Science.gov (United States)

Aidala, Christine

2007-10-01

Since my first research experience in 1996 working in low-energy nuclear structure, the results of which were presented at the original DNP CEU poster session in Santa Fe in 1998, subsequent projects led me to weave my way through various energies and collision systems in nuclear and particle physics. Through the course of the broad exposure to research that I have been fortunate enough to experience, I have found a niche for myself in the study of nucleon spin structure. I originally got involved in the field in 1998-99 through my undergraduate senior project on studies for polarizing the proton beam at HERA in Hamburg, Germany. After a foray into particle physics followed by an unanticipated diversion from research, teaching music and English abroad, fate--and some kind individuals--would give me the opportunity to return both to physics and specifically to nucleon structure in 2001 as part of the PHENIX experiment at the Relativistic Heavy Ion Collider. Six years into my research on proton spin structure as a member of the PHENIX Collaboration, I will discuss where I am today and the non-linear path that brought me here.

The project is coordinated by CEA with the other partners being: ADEME (co-funding), AFH2, CNRS, IFP, Air Liquide, EdF, GdF Suez, TOTAL, ALPHEA. The project is divided into 4 sub-projects, that address present and future French hydrogen industrial markets for chemical and refinery uses, the analysis of the interplay between wind energy production and storage of hydrogen for different automotive requirements (refuelling stations, BtL plants, H2/NG mix), massive hydrogen storage to balance various offer and demand characteristics, and the supply network (pipeline option competitiveness vs. trucked in supply) to distribute hydrogen in a French region for automotive applications. Technical and economical issues, as well as GHG emissions, are addressed. (orig.)

Les origines de l’entrepreneur schumpétérien The Origins of the Schumpeterian Entrepreneur

Directory of Open Access Journals (Sweden)

Jean-Jacques Gislain

2012-11-01

Full Text Available Cet article examine les deux origines, logique dans la théorie économique et historique dans l’histoire de la pensée économique, de l’entrepreneur chez J. A. Schumper. L’origine logique réside dans la nécessité analytique de construire un « type entrepreneur », comme type particulier d’agent économique, pour rendre intelligible le processus de transformation économique. Ce type permet le passage de l’analyse statique, le circuit walrasien, à celle dynamique de l’évolution économique. L’origine historique de ce type entrepreneur ne fait pas de Schumpeter un auteur aussi original que l’on pourrait le penser. Quelques années avant, de nombreux auteurs importants, et bien connus de Schumper, avaient déjà proposé des descriptions de l’entrepreneur très proches de celle de Schumpeter. Parmi ceux-ci, Max Weber, Werner Sombart, Alfred Marshall, Paul Leroy-Beaulieu et Friedrich von Wieser sont ici étudiés.This article examines both origins, logic in the economic theory and historic in the history of the economic thought, of the Schumpeterian entrepreneur. The logical origin lies in the analytical necessity of building a "typify entrepreneur", as particular type of economic agent, to make understandable the process of economic transformation. This type allows the passage of the static analysis, the walrasian circuit, that dynamics of the economic evolution. The historic origin of this type entrepreneur does not make Schumpeter a so original author as we could think of it. Some years before, numerous important authors, and known well by Schumper, had already proposed the descriptions of the entrepreneur very close to that of Schumpeter. Among these, Max Weber, Werner Sombart, Alfred Marshall, Paul Leroy-Beaulieu and Friedrich von Wieser are studied here.

Symbiotic Origin of Aging.

Greenberg, Edward F; Vatolin, Sergei

2018-06-01

Normally aging cells are characterized by an unbalanced mitochondrial dynamic skewed toward punctate mitochondria. Genetic and pharmacological manipulation of mitochondrial fission/fusion cycles can contribute to both accelerated and decelerated cellular or organismal aging. In this work, we connect these experimental data with the symbiotic theory of mitochondrial origin to generate new insight into the evolutionary origin of aging. Mitochondria originated from autotrophic α-proteobacteria during an ancient endosymbiotic event early in eukaryote evolution. To expand beyond individual host cells, dividing α-proteobacteria initiated host cell lysis; apoptosis is a product of this original symbiont cell lytic exit program. Over the course of evolution, the host eukaryotic cell attenuated the harmful effect of symbiotic proto-mitochondria, and modern mitochondria are now functionally interdependent with eukaryotic cells; they retain their own circular genomes and independent replication timing. In nondividing differentiated or multipotent eukaryotic cells, intracellular mitochondria undergo repeated fission/fusion cycles, favoring fission as organisms age. The discordance between cellular quiescence and mitochondrial proliferation generates intracellular stress, eventually leading to a gradual decline in host cell performance and age-related pathology. Hence, aging evolved from a conflict between maintenance of a quiescent, nonproliferative state and the evolutionarily conserved propagation program driving the life cycle of former symbiotic organisms: mitochondria.

Implementation of the Hungarian RW management project: Results and lessons

International Nuclear Information System (INIS)

Vigassy, J.; Czoch, I.; Ormai, P.

1995-01-01

In 1993, a National RW Management Project was launched to solve handling and disposal of LLW/ILW of the Paks Nuclear Power Plant and to elaborate a complex strategy for the management of radwastes from the NPP, including HLW, spent fuel and wastes from the decommissioning. It was intended to implement the project so as to have selected the possible site (or sites) for the LLW/ILW waste repository by 1996. This paper describes the first results of the nation-wide screening for suitable areas and the problems related to the comparative evaluation process to select potential sites for a surface or geological LLW/ILW disposal facility. International tenders were issued to find the most appropriate technology to reduce the quantity of liquid and solid radwaste in the Nuclear Power Plant. Their results will provide a better basis for planning the characteristics and quantity of radwaste. The applications revealed that supercompacting can be ordered as a service when the need arises, and thus it was possible to re-allocate the funding originally foreseen for the equipment to treat solid wastes. Great importance is attached in the Project to public acceptance and PR activity. An expert organization was selected in a two-phase bidding process, and it was decided that detailed exploration of a potential site will take place only if public acceptance is assured. The original program of the Hungarian RW Management Project was extended in 1994 to perform on-site underground investigations (with Canadian support) in a silt-stone formation. The first results confirm that this is a potential site for deep geological disposal of HLW. The financial and legal framework of the RW management is also to be solved. The new law on nuclear energy -- now in preparation -- will deal with that problem in one of its most important chapters, defining the responsibilities for RW management and the sources of funding

Test and evaluation plan for Project W-314 tank farm restoration and safe operations

International Nuclear Information System (INIS)

Hays, W.H.

1998-01-01

The ''Tank Farm Restoration and Safe Operations'' (TFRSO), Project W-314 will restore and/or upgrade existing Hanford Tank Farm facilities and systems to ensure that the Tank Farm infrastructure will be able to support near term TWRS Privatization's waste feed delivery and disposal system and continue safe management of tank waste. The capital improvements provided by this project will increase the margin of safety for Tank Farms operations, and will aid in aligning affected Tank Farm systems with compliance requirements from applicable state, Federal, and local regulations. Secondary benefits will be realized subsequent to project completion in the form of reduced equipment down-time, reduced health and safety risks to workers, reduced operating and maintenance costs, and minimization of radioactive and/or hazardous material releases to the environment. The original regulatory (e.g., Executive Orders, WACS, CFRS, permit requirements, required engineering standards, etc.) and institutional (e.g., DOE Orders, Hanford procedures, etc.) requirements for Project W-314 were extracted from the TWRS S/RIDs during the development of the Functions and Requirements (F and Rs). The entire family of requirements were then validated for TWRS and Project W-314. This information was contained in the RDD-100 database and used to establish the original CDR. The Project Hanford Management Contract (PHMC) team recognizes that safety, quality, and cost effectiveness in the Test and Evaluation (T and E) program is achieved through a planned systematic approach to T and E activities. It is to this end that the Test and Evaluation Plan (TEP) is created. The TEP for the TFRSO Project, was developed based on the guidance in HNF-IP-0842, and the Good Practice Guide GPG-FM-005, ''Test and Evaluation,'' which is derived from DOE Order 430.1, ''Life Cycle Asset Management.'' It describes the Test and Evaluation program for the TFRSO project starting with the definitive design phase and ending

Facing a heavy task, any single person can only make a limited contribution and team cooperation is needed. As one enjoys the benefit of the public goods, the potential benefits of the project are not always maximized and may be partly wasted. By incorporating individual ability and project benefit into the original public goods game, we study the coupling effect of the four parameters, the upper limit of individual contribution, the upper limit of individual benefit, the needed project cost and the upper limit of project benefit on the evolution of cooperation. Coevolving with the individual-level group size preferences, an increase in the upper limit of individual benefit promotes cooperation while an increase in the upper limit of individual contribution inhibits cooperation. The coupling of the upper limit of individual contribution and the needed project cost determines the critical point of the upper limit of project benefit, where the equilibrium frequency of cooperators reaches its highest level. Above the critical point, an increase in the upper limit of project benefit inhibits cooperation. The evolution of cooperation is closely related to the preferred group-size distribution. A functional relation between the frequency of cooperators and the dominant group size is found.

The integrated melter off-gas treatment systems at the West Valley Demonstration Project

Vance, R.F. [West Valley Nuclear Services Co., Inc., NY (United States)

1995-02-01

The West Valley Demonstration Project was established by Public Law 96-368, the {open_quotes}West Valley Demonstration Project Act, {close_quotes} on October 1, l980. Under this act, Congress directed the Department of Energy to carry out a high level radioactive waste management demonstration project at the Western New York Nuclear Service Center in West Valley, New York. The purpose of this project is to demonstrate solidification techniques which can be used for preparing high level radioactive waste for disposal. In addition to developing this technology, the West Valley Demonstration Project Act directs the Department of Energy to: (1) develop containers suitable for permanent disposal of the high level waste; (2) transport the solidified high level waste to a Federal repository; (3) dispose of low level and transuranic waste produced under the project; and (4) decontaminate and decommission the facilities and materials associated with project activities and the storage tanks originally used to store the liquid high level radioactive waste. The process of vitrification will be used to solidify the high level radioactive liquid wastes into borosilicate glass. This report describes the functions, the controlling design criteria, and the resulting design of the melter off-gas treatment systems which are used in the vitrification process.

2000-02-01

The Fort McMurray Demonstration Project in Social Marketing is a multifaceted program that applies the techniques of social marketing to health and safety. This paper describes the origins of the project and the principles on which it was based. VENUE: Fort McMurray, in the province of Alberta, Canada, was selected because the community had several community initiatives already underway and the project had the opportunity to demonstrate "value added." The project is distinguished from others by a model that attempts to achieve mutually reinforcing effects from social marketing in the community as a whole and from workplace safety promotion in particular. Specific interventions sponsored by the project include a media campaign on cable television, public activities in local schools, a community safety audit, and media appearance by a mascot that provides visual identity to the project, a dinosaur named "Safetysaurus." The project integrated its activities with other community initiatives. The evaluation component emphasizes outcome measures. A final evaluation based on injury rates and attitudinal surveys is underway. Baseline data from the first round of surveys have been compiled and published. In 1995, Fort McMurray became the first city in North America to be given membership in the World Health Organization's Safe Community Network.

Origins and Consequences of Religious Restrictions: A Global Overview

Science.gov (United States)

Finke, Roger

2014-01-01

Despite the international controversies surrounding religious restrictions and freedoms, the topic has only recently received substantial research attention. Drawing on this new body of research, and multiple research projects in progress, this address explores both the origins and consequences of religious restrictions in the global arena. To understand the motives for restrictions, I propose hypotheses in three areas: the relationship or lack of relationship between institutional religion and the state, the willingness and capacity of the state to ensure freedoms, and the larger social and cultural pressures restricting freedoms, including social and political movements targeting minority religions. Turning to the consequences of religious restrictions, I explore how and why restrictions alter the religious economy (i.e., formation, supply and operation of religions) and are associated with higher levels of religious persecution, religious violence and intrastate conflict in general. Finally, I review additional areas where research is needed. PMID:25364225

Origin of life experts might find inspiration at CERN

“How did life appear on Earth?” That was the unanswered question on attendees’ minds at a single-day workshop held at CERN, 20 May. The brainstorming session featured experts from the biology field and CERN physicists. Although the million-dollar question wasn't answered, the group explored the possibility of organising a large-scale research project that could do just that.   Darwin’s vision of "descent with modification" from his "B" notebook. According to workshop chair Stuart Kauffman, an American theoretical biologist, currently Finland Distinguished Professor (FiDiPro) at the Tampere University of Technology: “The Origin of Life problem began with Louis Pasteur, who refused to believe in the ‘spontaneous generation principle’ of life. All life, he said, comes from life. This left Pasteur in a conundrum: how did life start in the first place?” As a renowne...

The Historical Origins and Economic Logic of 'Open Science'

CERN Multimedia

CERN. Geneva

2008-01-01

Modern "big science" projects, such as the LHC experiments in physics that are being prepared to run at CERN, embody the distinctive ethos of cooperation and mechanisms of coordination among distributed groups of researchers that are characteristic of 'open science'. Much has been written about the institutions of open science, their supporting social norms, and their effectiveness in generating additions to the stock of reliable knowledge. But from where have these institutions and their supporting ethos come? How robust can we assume them to be in the face of the recent trends for universities and research institutes in some domains of science to seek to appropriate the benefits of new discoveries and inventions by asserting intellectual property claims? A search for the historical origins of the institutions of open science throws some new light on these issues, and the answers may offer some lessons for contemporary science and technology policy-making.

The vast majority of the known dwarf-planet sized bodies are bright enough to be studied through optical and infrared spectroscopy. As a result, we have an understanding of the surface properties for the largest Kuiper belt objects (KBOs) which retain their primordial inventory of volatile ices. For the typically smaller > 22 mag KBO, we must rely instead on what colors reveal by proxy; yet this picture remains incomplete. Most KBO physical property studies examine the hodgepodge set of objects discovered by various surveys with different and varying detection biases that make it difficult if not impossible to reliably estimate the sizes of the different surface color groupings (compositional classes) residing in the modern-day Kuiper belt.The Colours of the Outer Solar System Origins Survey (Col-OSSOS) probes the surface properties within the Kuiper belt primarily through near simultaneous g,r and J colors with the Gemini North Telescope and u-band with Canada-France-Hawaii Telescope. The project aims to target ~100 KBOs brighter than 23.6 r‧ mag found by the Outer Solar System Origins Survey (OSSOS), a survey with a well-measured detection efficiency. Thus, Col-OSSOS provides the first brightness-complete, compositional-dynamical map of the Outer Solar System, probing in a new light the radial color distribution in the primordial planetesimal disk from which KBOs originated. We will provide an update on the current status of the program highlighting results from the first two years of the survey; including size estimates of the two color KBO subgroups (the red and neutral surfaces) within the dynamically excited Kuiper belt and implications for the early planetesimal disk composition based on neutral-colored binaries found in the cold classical Kuiper belt.

Project-level impact assessment was originally conceived as a snapshot taken in advance of project implementation, contrasting current conditions with a likely future scenario involving a variety of predicted impacts. Current best practice guidance has encouraged a shift towards longitudinal assessments from the pre-project stage through the implementation and operating phases. Experience and study show, however, that assessment of infrastructure-intensive projects rarely endures past the project's construction phase. Negative consequences for environmental, social and health outcomes have been documented. Such consequences clarify the pressing need for longitudinal assessment in each of these domains, with human rights impact assessment (HRIA) as an umbrella over, and critical augmentation of, environmental, social and health assessments. Project impacts on human rights are more closely linked to political, economic and other factors beyond immediate effects of a company's policy and action throughout the project lifecycle. Delineating these processes requires an adequate framework, with strategies for collecting longitudinal data, protocols that provide core information for impact assessment and guidance for adaptive mitigation strategies as project-related effects change over time. This article presents general principles for the design and implementation of sustained, longitudinal HRIA, based on experience assessing and responding to human rights impact in a uranium mining project in Malawi. The case study demonstrates the value of longitudinal assessment both for limiting corporate risk and improving human welfare. - Graphical abstract: Assessing changes in human rights condition as affected by both project and context, over time. - Highlights: • Corporate capital projects affect human rights in myriad ways. • Ongoing, longitudinal impact assessment techniques are needed. • We present an approach for conducting longitudinal human rights impact

The United Nations Development Program (UNDP) project was conceived in April 1985, implementation was started on preliminary authorization by summer 1986, and it was approved and signed in early 1987. The duration was originally planned for three years with a UNDP input of US$ 1,657.500 (including Government cost sharing of US$ 280,000). The project is now essentially completed with a few items still pending, though committed as firmly planned, and the current cost estimate is US$ 1,707.617. The objective of the project was to assist in establishing long-term training programmes in two training centres in the People's Republic of China (Qinshan and Suzhou) and strengthen the training capabilities at these centres. The two centres are intended to provide specialized comprehensive training in basic and applied nuclear power engineering disciplines as well as in construction, operation and maintenance of nuclear power plants to technical personnel assigned to the nuclear power plants in the People's Republic of China

Purpose Canada's primary care system has been described as "a culture of pilot projects" with little evidence of converting successful initiatives into funded, permanent programs or sharing project outcomes and insights across jurisdictions. Health services pilot projects are advocated as an effective strategy for identifying promising models of care and building integrated care partnerships in local settings. In the qualitative study reported here, the purpose of this paper is to investigate the strengths and challenges of this approach. Design/methodology/approach Semi-structured interviews were conducted with 34 primary care physicians who discussed their experiences as pilot project leads. Following thematic analysis methods, broad system issues were captured as well as individual project information. Findings While participants often portrayed themselves as advocates for vulnerable patients, mobilizing healthcare organizations and providers to support new models of care was discussed as challenging. Competition between local healthcare providers and initiatives could impact pilot project success. Participants also reported tensions between their clinical, project management and research roles with additional time demands and skill requirements interfering with the work of implementing and evaluating service innovations. Originality/value Study findings highlight the complexity of pilot project implementation, which encompasses physician commitment to addressing care for vulnerable populations through to the need for additional skill set requirements and the impact of local project environments. The current pilot project approach could be strengthened by including more multidisciplinary collaboration and providing infrastructure supports to enhance the design, implementation and evaluation of health services improvement initiatives.

Full Text Available Modern management theory treats all complex tasks and duties like projects and make these projects possible to be managed by a particular organizational-management concept in order to achieve a goal effectively. A large number of jobs and tasks performed in the system of defense or for defense purposes have the characteristics of projects. Project management is both a skill and a science of monitoring human, material, financial, energy and other resources to achieve required objectives within the given limits: deadlines, time, budget, possibility of realization and the satisfaction of the interests of all project participants. Project management is a traditional area of applied (or functional management focused on managing complex and uncertain situations with defined goals. Introduction In conditions of rapid change and high uncertainty, only adaptive organizations survive, i. e. those that are able not only to react quickly to changes but also to proactively take advantage of changes. Development of project management The biggest influence on the development of the area had complex jobs within the engineering profession. In parallel with the traditional approach new approaches began to develop, while the traditional one still remained in use. Contrary to the traditional engineering approach, a dynamic model first developed in order to respond to demands for greater control of costs. Project management Project management is a skill and knowledge of human and material resources to achieve set objectives within prescribed limits: deadlines, time, budget, possibility of realization, and the satisfaction of all participants in the project. In order to realize a project effectively, it is necessary to manage it rationally.

Genetic algorithm for project time-cost optimization in fuzzy environment

Directory of Open Access Journals (Sweden)

Khan Md. Ariful Haque

2012-12-01

Full Text Available Purpose: The aim of this research is to develop a more realistic approach to solve project time-cost optimization problem under uncertain conditions, with fuzzy time periods. Design/methodology/approach: Deterministic models for time-cost optimization are never efficient considering various uncertainty factors. To make such problems realistic, triangular fuzzy numbers and the concept of a-cut method in fuzzy logic theory are employed to model the problem. Because of NP-hard nature of the project scheduling problem, Genetic Algorithm (GA has been used as a searching tool. Finally, Dev-C++ 4.9.9.2 has been used to code this solver. Findings: The solution has been performed under different combinations of GA parameters and after result analysis optimum values of those parameters have been found for the best solution. Research limitations/implications: For demonstration of the application of the developed algorithm, a project on new product (Pre-paid electric meter, a project under government finance launching has been chosen as a real case. The algorithm is developed under some assumptions. Practical implications: The proposed model leads decision makers to choose the desired solution under different risk levels. Originality/value: Reports reveal that project optimization problems have never been solved under multiple uncertainty conditions. Here, the function has been optimized using Genetic Algorithm search technique, with varied level of risks and fuzzy time periods.

STRATEGIC MAPS AND CRITICAL FACTORS FOR PROJECT MANAGEMENT MATURITY: A PROPOSAL

Directory of Open Access Journals (Sweden)

Sady Darcy Silva Junior

2010-06-01

Full Text Available Project Management (PM and Strategic Management (SM are two subjects of growing importance in the corporate environment which are normally considered in isolation. One way of integrating these two concepts might be via the concept of project management maturity (Westphal et al., 2008. Rabechini and Pessoa (2005 state that to obtain project management maturity, it is necessary to achieve success in a number of critical factors which include organizational culture and structure, as well as sponsorship at both tactical and strategic levels (Silva et al., 2008. Another way of achieving this connection is by using Balanced Scorecard (BSC as an auxiliary tool to integrate between projects and organizational strategy (Brock et al., 2003. The original developers of the BSC, Kaplan e Norton, subsequently developed the concept of strategy mapping, which they affirm "represents the missing link between the formulation and the execution of the strategy" (Kaplan e Norton, 2004. This paper proposes a strategy map identifying critical factors for attaining project management maturity. To formulate the map, we used a qualitative, exploratory approach oriented by Project Management theory and strategy mapping. We first identified 13 critical factors, then developed a strategy map, which was evaluated by six specialists (three in SM area and three in PM area.The results suggest links between strategic mapping nad critical factors in project management. It also contributes to both areas independently. Specifically, the study identifies critical factors for project management maturity while demonstrating the applicability of strategic mapping techniques to Balanced Scorecard concepts.

Full Text Available The characterization of multifloral honey regarding the mineral composition, sugar content and basic physicochemical properties has been done. The total of 164 honey samples was collected from six regions of Serbia during 2009 harvesting season. Univariate data analysis (descriptive statistics and analysis of variance, geographic information system and pattern recognition methods (principal component analysis and cluster analysis have been performed in order to identify geographical origin of honey. The content of Mg, K, and Cu, electrical conductivity, and optical rotation were established as useful indicators in tracing regional differences between honey samples. Samples originated from Zlatibor region were clearly distinguished from those from the rest of Serbia showing higher K and Mg content, as well as higher values of optical rotation, electrical conductivity, and free acidity. The influence of the soil composition, and climate conditions, as well as the presence of particular flora on the honey composition is stressed out. The modeling of geographic origin of honey has been attempted by the means of linear discriminant analysis.

2010-05-01

Full Text Available The Positron-Electron Project II (PEP-II B Factory collider ended the final phase of operation at nearly twice the design current and 4X the design luminosity. In the ultimate operation state, eight 1.2 MW radio-frequency (rf klystrons and 12 accelerating cavities were added beyond the original implementation, and the two storage rings were operating with longitudinal instability growth rates roughly 5X in excess of the original design estimates. From initial commissioning there has been continual adaptation of the low level rf (LLRF control strategies, configuration tools, and some new hardware in response to unanticipated technical challenges. This paper offers a perspective on the original LLRF and longitudinal instability control design, and highlights via two examples the system evolution from the original design estimates through to the final machine with 1.2×10^{34} luminosity. The impact of unanticipated signals in the coupled-bunch longitudinal feedback and the significance of nonlinear processing elements in the LLRF systems are presented. We present valuable “lessons learned” which are of interest to designers of next generation feedback and impedance controlled LLRF systems.

Automotive Stirling Engine Development Project

1997-01-01

The development and verification of automotive Stirling engine (ASE) component and system technology is described as it evolved through two experimental engine designs: the Mod 1 and the Mod 2. Engine operation and performance and endurance test results for the Mod 1 are summarized. Mod 2 engine and component development progress is traced from the original design through hardware development, laboratory test, and vehicle installation. More than 21,000 hr of testing were accomplished, including 4800 hr with vehicles that were driven more dm 59,000 miles. Mod 2 engine dynamometer tests demonstrated that the engine system configuration had accomplished its performance goals for power (60 kW) and efficiency (38.5%) to within a few percent. Tests with the Mod 2 engine installed in a delivery van demonstrated combined metro-highway fuel economy improvements consistent with engine performance goals and the potential for low emission levels. A modified version of the Mod 2 has been identified as a manufacturable design for an ASE. As part of the ASE project, the Industry Test and Evaluation Program (ITEP), NASA Technology Utilization (TU) project, and the industry-funded Stirling Natural Gas Engine program were undertaken to transfer ASE technology to end users. The results of these technology transfer efforts are also summarized.

2013-02-01

Project TALENT is a US national longitudinal study of about 377,000 individuals born in 1942-1946, first assessed in 1960. Students in about 1,200 schools participated in a 2-day battery covering aptitudes, abilities, interests, and individual and family characteristics (Flanagan, 1962; www.projectTALENT.org). Follow-up assessments 1, 5, and 11 years later assessed educational and occupational outcomes. The sample includes approximately 92,000 siblings from 40,000 families, including 2,500 twin pairs and 1,200 other siblings of twins. Until recently, almost no behavior genetic research has been conducted with the sample. In the original data collection information was not collected with the intent to link family members. Recently, we developed algorithms using names, addresses, birthdates, and information about family structure to link siblings and identify twins. We are testing several methods to determine zygosity, including use of yearbook photographs. In this paper, we summarize the design and measures in Project TALENT, describe the Twin and Sibling sample, and present our twin-sib-classmate model. In most twin and family designs, the 'shared environment' includes factors specific to the family combined with between-family differences associated with macro-level variables such as socioeconomic status. The school-based sampling design used in Project TALENT provides a unique opportunity to partition the shared environment into variation shared by siblings, specific to twins, and associated with school- and community-level factors. The availability of many measured characteristics on the family, schools, and neighborhoods enhances the ability to study the impact of specific factors on behavioral variation.

The corpus callosum establishes the anatomical continuity between the 2 hemispheres and coordinates their activity. Using histological tracing, single axon reconstructions, and diffusion tractography, we describe a callosal projection to n caudatus and putamen in monkeys and humans. In both species......, the origin of this projection is more restricted than that of the ipsilateral projection. In monkeys, it consists of thin axons (0.4–0.6 µm), appropriate for spatial and temporal dispersion of subliminal inputs.

Origin of tektites

Science.gov (United States)

O'Keefe, John A.

1994-01-01

The origin of tektites has been obscure because of the following dilemma. The application of physical principles to the data available on tektites points strongly to origin from one or more lunar volcanoes; but few glasses of tektite composition have hitherto been reported from the lunar samples. Instead, the lunar silicic glasses consist chiefly of a material very rich in K2O and poor in MgO. The ratio of K2O/MgO is higher in these glasses than in any tektites reported. The solution of the dilemma seems to come from the study of some recently discovered terrestrial deposits of tektite glass with high values of K2O/MgO at the Cretaceous Tertiary boundary. These glasses are found to be very vulnerable to crystallization into sandine or to alteration to smectite. These end products are known and are more abundant than any terrestrial deposits of tektite glass. It seems possible that, in fact, the moon produces tektite glass, mostly of the high K2O-low MgO type; but on Earth these deposits are destroyed. The much less abundant deposits with lower K and higher Mg are observed because they survive. Other objections to the lunar origin hypothesis appear to be answerable.

Project management of life-science research projects: project characteristics, challenges and training needs.

Science.gov (United States)

Beukers, Margot W

2011-02-01

Thirty-four project managers of life-science research projects were interviewed to investigate the characteristics of their projects, the challenges they faced and their training requirements. A set of ten discriminating parameters were identified based on four project categories: contract research, development, discovery and call-based projects--projects set up to address research questions defined in a call for proposals. The major challenges these project managers are faced with relate to project members, leadership without authority and a lack of commitment from the respective organization. Two-thirds of the project managers indicated that they would be interested in receiving additional training, mostly on people-oriented, soft skills. The training programs that are currently on offer, however, do not meet their needs. Copyright © 2010 Elsevier Ltd. All rights reserved.

Davis, Ronald M; Douglas, Clifford E; Beasley, John K

2006-12-01

Research on previously secret tobacco industry documents has grown substantially during the past decade, since these documents first became available as the result of private and governmental litigation and investigations by the US Congress and the US Food and Drug Administration. Complementary research on tobacco litigation testimony is now being conducted through the Tobacco Deposition and Trial Testimony Archive (DATTA) project. We obtained transcripts of depositions and trial testimony, deposition and trial exhibits, expert reports, and other litigation documents from law firms, court reporter firms, individual lawyers and witnesses, tobacco company websites, and other sources. As of 3 March 2006, the publicly available collection of DATTA (http://tobaccodocuments.org/datta) contained 4850 transcripts of depositions and trial testimony, including a total of about 820,000 transcript pages. Transcripts covered testimony from 1957 to 2005 (85% were for testimony from 1990 to 2005) given by more than 1500 witnesses in a total of 232 lawsuits. Twelve research teams were established to study the transcripts, with each team covering a particular topic (for example, the health consequences of tobacco use, addiction and pharmacology, tobacco advertising and promotion, tobacco-product design and manufacture, economic impact of tobacco use, youth initiation of tobacco use, and public understanding of the risks of tobacco use and exposure to second-hand smoke). The teams used qualitative research methods to analyse the documents, and their initial findings are published throughout this journal supplement.

2006-01-01

Objective: To evaluate the role of 16-slice spiral computed tomography angiography (MSCTA) to identify the anomalous origin and anatomic course of the right coronary artery (RCA) with conventional X-ray coronary angiography (CAG) serving as standard of reference. Methods: MSCTA data in 8 patients with anomalous RCA were retrospectively analyzed for the study, 7 of them had also undergone CAG examinations. MSCTA and CAG images were analyzed in blinded fashion for accuracy of anomalous artery origin and path detection. Results were compared in a secondary consensus evaluation. Virtual endoscopy (VE) was used to evaluate the orifice of the anomalous arteries and its relationship with the adjacent ostia of normal arteries. Multi-planar reconstruction (MPR), curved MPR, thin-slab maximum intensity projection (MIP), volume rendering (VR) or slab VR (cut-plane VR) were used to assess the aberrant path of the RCA and its relationship with the adjacent large vessels. At least two views of the RCA were analyzed on CAG. Results: The anomalous RCA for all 8 patients were correctly displayed on MSCTA. RCA originated from the left sinus of Valsalva in 6 patients, one RCA from the end of left main coronary artery, another RCA arose from the posterior sinus of Valsalva. The anomalous ostia showed no stenosis. All of them passed between the aortic root and the pulmonary artery. For 7 patients with CAG alone correct identification of the abnormality was achieved in only 71%. Conclusion: MSCTA was superior to show the anomalous orifice and path of the RCA, it should be considered as a prime non-invasive imaging tool for suspected coronary anomalies. (authors)

A successful waste stream analysis on a large construction project in a radiologically controlled area

Kennicott, M.; Richardson, D.; Starke, T.P.

1997-01-01

The Los Alamos National Laboratory (the Laboratory) Chemistry and Metallurgy Research (CMR) Facility, constructed in 1952, is currently under going a major, multi-year demolition and construction project. Many of the operations required under this project (i.e., design, demolition, decontamination, construction, and waste management) mimic the processes required of a large scale decontamination and decommissioning (D and D) job and are identical to the requirements of any of several upgrades projects anticipated for the laboratory and other Department of Energy (DOE) sites. For these reasons the CMR upgrades Project is seen as an ideal model facility--to test the application and measure the success of waste minimization techniques which could be implemented for any similar projects. The purpose of this paper will be to discuss the successful completion of a waste stream analysis. The analyses performed was to measure the potential impact of waste generation, in terms of volume and costs, for a reconfiguration option being considered to change the approach and execution of the original project

An overview of the ITER project

International Nuclear Information System (INIS)

Holtkamp, N.

2007-01-01

The ITER Project Team now coming together in Cadarache is currently being shaped from the old, preserving the legacy of technical know-how built up in the ITER Joint Central Team since 1992. It is particularly strong initially in the most urgent areas, related to long lead items - magnets, the main vessel and the buildings - as well as in work related to licensing. But it also incorporates new functional needs - financial, administrative, and procurement - and ties in the needs of future users during operation. Since the bulk of the procurement for ITER will be provided in kind, efforts have been strengthened to define better the share of responsibilities with the Parties' Domestic Agencies. The procurement cost sharing is being transferred into realistic technical splitting of the work, with agreements between the Parties to demonstrate production of the necessary quality, and how to handle any shortcomings. The design has evolved since originally conceived and valued 5 years ago. Design reviews of specific procurements will therefore start in September 2006 to ensure the current manufacturing and design assumptions continue to satisfy requirements. This paper reviews the current status of development of the ITER project, covering organisational and technical issues

Origin of solar radio waves

International Nuclear Information System (INIS)

Olmr, J.

1977-01-01

Solar radiowave radiation amounts to about 10 -7 of the total solar radiation. The solar atmosphere emits radiation of different wavelengths from a fraction of nanometer to kilometer waves. The solar radiowaves are of thermal origin and except for neutral hydrogen emission and solid body radio emission their emission always results from free electrons. The radiowave radiation active components were classified in several types, such as noise storms, flashes, flares, continuum, and flashes lasting for several minutes. The respective types are discussed and their origins shown. The mechanisms are described permitting the formation of radio waves of nonthermal origin, i.e., plasma oscillations, gyromagnetic emission, synchrotron and Cherenkov radiations. (J.P.)

Optimal projection of observations in a Bayesian setting

KAUST Repository

Giraldi, Loic

2018-03-18

Optimal dimensionality reduction methods are proposed for the Bayesian inference of a Gaussian linear model with additive noise in presence of overabundant data. Three different optimal projections of the observations are proposed based on information theory: the projection that minimizes the Kullback–Leibler divergence between the posterior distributions of the original and the projected models, the one that minimizes the expected Kullback–Leibler divergence between the same distributions, and the one that maximizes the mutual information between the parameter of interest and the projected observations. The first two optimization problems are formulated as the determination of an optimal subspace and therefore the solution is computed using Riemannian optimization algorithms on the Grassmann manifold. Regarding the maximization of the mutual information, it is shown that there exists an optimal subspace that minimizes the entropy of the posterior distribution of the reduced model; a basis of the subspace can be computed as the solution to a generalized eigenvalue problem; an a priori error estimate on the mutual information is available for this particular solution; and that the dimensionality of the subspace to exactly conserve the mutual information between the input and the output of the models is less than the number of parameters to be inferred. Numerical applications to linear and nonlinear models are used to assess the efficiency of the proposed approaches, and to highlight their advantages compared to standard approaches based on the principal component analysis of the observations.

Fernandez, R. A.; Torralbo, J. R.

2004-01-01

NUCLENOR has been developing lifetime management and modernisation activities at Santa Maria de Garona NPP since the end of the 80's and the plant is now in optimum technical conditions to continue in operation beyond its original lifetime planned in the design (40 years). In the USA, the country of origin of the project, a good number of power plants with a similar design, age and history to SMG are in the process of obtaining or have already obtained, a licensing extension of up to 60 years from the NRC. In Spain, the activities required for requesting a long-term operating licensing extension include the Ageing Assessment and Management of the plant systems, structures and components, in accordance with the american regulation 10CFR54, a Radiological Impact Study for the new operating period, and an Analysis of New Legislation, not included in the licensing bases and considered to be important to safety by the CSN. With a view to obtaining a renewal of the current operating permit for the period 2009-2019, NUCLENOR has launched the Proyecto 2019, which extends to technical and licensing aspects, as it involves all the company's personnel.

Hartmann, Ieneke J.C.; Remy-Jardin, Martine; Menchini, Laura; Teisseire, Antoine; Khalil, Chadi; Remy, Jacques

2007-01-01

The purpose of this study was to determine non-invasively the frequency of ectopic bronchial arteries (BA) (i.e., bronchial arteries originating at a level of the descending aorta other than T5-T6 or from any aortic collateral vessel) on multidetector-row CT angiograms (CTA) obtained in patients with hemoptysis. Over a 5-year period (2000-2005), 251 consecutive patients with hemoptysis underwent multidetector-row CT angiography of the thorax. From this population, 37 patients were excluded because of a suboptimal CTA examination (n = 19), the presence of extensive mediastinal disease (n = 15) or severe chest deformation (n = 3) precluding any precise analysis of the bronchial arteries at CTA. Our final study group included 214 patients who underwent a thin-collimated CT angiogram (contrast agent: 300 to 350 mg/ml) on a 4- (n = 56), 16- (n = 119) and 64- (n = 39) detector-row scanner. The site of origin and distribution of bronchial arteries were analyzed on transverse CT scans, maximum intensity projections and volume-rendered images. The site of the ostium of a bronchial artery was coded as orthotopic when the artery originated from the descending aorta between the levels of the fifth and sixth thoracic vertebrae; all other bronchial arteries were considered ectopic. From the studied population, 137 (64%) patients had only orthotopic bronchial arteries, whereas 77 patients (36%) had at least one bronchial artery of ectopic origin. A total of 147 ectopic arteries were depicted, originating as common bronchial trunks (n = 23; 19%) or isolated right or left bronchial arteries (n = 101; 81%). The most frequent sites of origin of the 124 ostiums were the concavity of the aortic arch (92/124; 74%), the subclavian artery (13/124; 10.5%) and the descending aorta (10/124; 8.5%). The isolated ectopic bronchial arteries supplied the ipsilateral lung in all but three cases. Bronchial artery embolization was indicated in 26 patients. On the basis of CTA information, (1

DNA replication origins-where do we begin?

Science.gov (United States)

Prioleau, Marie-Noëlle; MacAlpine, David M

2016-08-01

For more than three decades, investigators have sought to identify the precise locations where DNA replication initiates in mammalian genomes. The development of molecular and biochemical approaches to identify start sites of DNA replication (origins) based on the presence of defining and characteristic replication intermediates at specific loci led to the identification of only a handful of mammalian replication origins. The limited number of identified origins prevented a comprehensive and exhaustive search for conserved genomic features that were capable of specifying origins of DNA replication. More recently, the adaptation of origin-mapping assays to genome-wide approaches has led to the identification of tens of thousands of replication origins throughout mammalian genomes, providing an unprecedented opportunity to identify both genetic and epigenetic features that define and regulate their distribution and utilization. Here we summarize recent advances in our understanding of how primary sequence, chromatin environment, and nuclear architecture contribute to the dynamic selection and activation of replication origins across diverse cell types and developmental stages. © 2016 Prioleau and MacAlpine; Published by Cold Spring Harbor Laboratory Press.

Third harmonic system was originally developed by Fermilab for FLASH facility at DESY and then was adopted and modified by INFN for the XFEL project [1-3]. In contrast to XFEL project, all cryomodules in LCLS-II project will operate in CW regime with higher RF average power for 1.3 GHz and 3.9 GHz cavities and couplers. Design of the cavity and fundamental power coupler has been modified to satisfy LCLS-II requirements. In this paper we discuss the results of COMSOL thermal and mechanical analysis of the 3.9 GHz coupler and cavity to verify proposed modifica-tion of the design. For the dressed cavity we present simulations of Lorentz force detuning, helium pressure sensitivity df/dP and major mechanical resonances.

Full Text Available Purpose: Within project-based supply chain inter-organizational cooperative innovation, the achievement of project value-adding reflects by factors such as project-based organizational effect level, the relationship between project cooperative innovation objectives etc. The purpose is to provide a reliable reference for the contractor reasonably allocate the effect level and resources between the knowledge input and innovation stage and realize the knowledge collaboration for project-based supply chain. Design/methodology/approach: Based on the assumption of equal cooperation between project-based organizations, from the view of maximizing project value-adding and the relationship of effect cost between knowledge input and innovation stage in consideration, the knowledge collaborative incentive model for project-based supply chain inter-organizational cooperative innovation was established, and solved through the first-order and second-order approach, then the digital simulation and example analysis were presented. Findings: The results show that, the project management enterprise resorted to adjust project knowledge collaboration incentive intensity and implemented knowledge input-innovation coordinative incentive strategy, not only could achieve project value-adding maximization, but also could realize net earnings Pareto improvement between project management enterprise and contractor. Research limitations/implications: To simplify the knowledge flow among project-based organizations, the knowledge flow in the model hypothesis is presented as knowledge input and knowledge innovation stage, thus it may affect the final analysis results. Originality/value: In construction project practice, knowledge is become more and more important to achieve project value-adding. The research can provide a theoretical guideline for the project-based organizations, such as the contractor, the owner, especially how to utilize their core knowledge.

compromised. This project provided non-destructive intrusion, isolation and automated response solution, achieving a goal of the Department of Energy (DOE) Roadmap to Secure Control Systems. It also addressed CIP-007-R4 which requires asset owners to employ malicious software prevention tools on assets within the electronic security perimeter. In addition, the CIP-007-R3 requirement for security patch management is minimized because white listing narrows the impact of vulnerabilities and patch releases. The exe-Guard Project completed all tasks identified in the statement of project objective and identified additional tasks within scope that were performed and completed within the original budget. The cost share was met and all deliverables were successfully completed and submitted on time. Most importantly the technology developed and commercialized under this project has been adopted by the Energy sector and thousands of devices with exe-Guard technology integrated in them have now been deployed and are protecting our power systems today

The origin of the lower fourth molar in canids, inferred by individual variation

Full Text Available Background An increase in tooth number is an exception during mammalian evolution. The acquisition of the lower fourth molar in the bat-eared fox (Otocyon megalotis, Canidae, Carnivora, Mammalia is one example; however, its developmental origin is not clear. In some canids (Canidae, individual variation exist as supernumerary molar M4. This study focuses on the acquisition of the lower fourth molar in canids and proposes that the inhibitory cascade model can explain its origin. Methods Occlusal view projected area of lower molars was determined from 740 mandibles obtained from Canis latrans, Nyctereutes procyonoides, and Urocyon cinereoargenteus museum specimens. For each molar, relative sizes of molars (M2/M1 and M3/M1 scores affected by inhibition/activation dynamics during development, were compared between individuals with and without supernumerary molar (M4. Results Possession of a supernumerary molar was associated with significantly larger M2/M1 score in Canis latrans, M3/M1 score in Nyctereutes procyonoides, and M2/M1 and M3/M1 scores in Urocyon cinereoargenteus compared to individuals of these species that lacked supernumerary molars. Discussion We propose that, in canids, the supernumerary fourth molar is attributable to reduced inhibition and greater activation during molar development. In the bat-eared fox, altered inhibition and activation dynamics of dental development during omnivorous-insectivorous adaptation may be a contributing factor in the origin of the lower fourth molar.

Full Text Available The study analyzes the role of project leadership facets on effective project outcome. Numerous such initiatives have already been taken on project outcome/performance in the context of apposite leadership styles or project management. However, the current study is unique in the milieu of project outcome that it introduces a new leadership approach, which throws light on the significance of variant leadership facets on project outcome. The study uses explanatory approach; primary data is collected from project management professionals working in different project organizations. The study uses structural equation model (SEM technique to test the hypothesis. The study found a positive relationship between project leadership facets and project outcome.

The question of the mode of origin of modern humans (Homo sapiens) has dominated palaeoanthropological debate over the last decade. This review discusses the main models proposed to explain modern human origins, and examines relevant fossil evidence from Eurasia, Africa and Australasia. Archaeological and genetic data are also discussed, as well as problems with the concept of 'modernity' itself. It is concluded that a recent African origin can be supported for H. sapiens, morphologically, be...

The idea of genetic authenticity and origin has been an important issue within genetics for decades for scientific, political, and economic reasons. The question of where species and populations come from, as well as the linking of genetic traits to particular geographical locations, has resurfaced....... Using the case of human and non-human genetics to compare and contrast the various facets associated with genetic identity, we seek to develop a broader picture of the ways in which genetics plays an important role in stabilizing categories of origin....

In silico reversal of repeat-induced point mutation (RIP identifies the origins of repeat families and uncovers obscured duplicated genes

Full Text Available Abstract Background Repeat-induced point mutation (RIP is a fungal genome defence mechanism guarding against transposon invasion. RIP mutates the sequence of repeated DNA and over time renders the affected regions unrecognisable by similarity search tools such as BLAST. Results DeRIP is a new software tool developed to predict the original sequence of a RIP-mutated region prior to the occurrence of RIP. In this study, we apply deRIP to the genome of the wheat pathogen Stagonospora nodorum SN15 and predict the origin of several previously uncharacterised classes of repetitive DNA. Conclusions Five new classes of transposon repeats and four classes of endogenous gene repeats were identified after deRIP. The deRIP process is a new tool for fungal genomics that facilitates the identification and understanding of the role and origin of fungal repetitive DNA. DeRIP is open-source and is available as part of the RIPCAL suite at http://www.sourceforge.net/projects/ripcal.

An original approach to data acquisition: CHADAC

Many labs try to boost existing data acquisition systems by inserting high performance intelligent devices in the important nodes of the system's structure. This strategy finds its limits in the system's architecture. The CHADAC project proposes a simple and efficient solution to this problem, using a multiprocessor modular architecture. CHADAC main features are: a) Parallel acquisition of data: CHADAC is fast; it dedicates one processor per branch; each processor can read and store one 16 bit word in 800 ns. b) Original structure: each processor can work in its own private memory, in its own shared memory (double access) and in the shared memory of any other processor (this feature being particulary useful to avoid wasteful data transfers). Simple and fast communications between processors are also provided by local DMA'S. c) Flexibility: each processor is autonomous and may be used as an independent acquisition system for a branch, by connecting local peripherals to it. Adjunction of fast trigger logic is possible. By its architecture and performances, CHADAC is designed to provide a good support for local intelligent devices and transfer operators developped elsewhere, providing a way to implement systems well fitted to various types of data acquisition.

This issue of "Continental Shelf Research" is dedicated to the study of processes potentially responsible for the relatively high productivity of the North Aegean Sea in comparison to other regions of the Eastern Mediterranean. This region, one of the most important fishing grounds in the eastern Mediterranean, is characterized by: i) the inflow of mesotrophic waters of Black Sea (BSW) origin into the North Aegean and their interaction with the more saline Levantine waters (LW); and ii) the wind-generated coastal upwelling occurring every summer in the eastern Aegean. The study of these two natural fertilization mechanisms has been the major aim of the AegeanMarTech project ("Technological and oceanographic cooperation Network for the Study of mechanisms fertilizing the North-East Aegean Sea").
