    DeSimpelaere, Edward

    2011-01-01

    The last thirty years have seen the Space Shuttle as the prime United States spacecraft for manned spaceflight missions. Many lessons have been learned about spacecraft design and operation throughout these years. Over the next few decades, a large increase of manned spaceflight in the commercial sector is expected. This will result in the exposure of commercial crews and passengers to many of the same risks crews of the Space Shuttle have encountered. One of the more dire situations that can be encountered is the loss of pressure in the habitable volume of the spacecraft during on orbit operations. This is referred to as a cabin leak. This paper seeks to establish a general cabin leak response philosophy with the intent of educating future spacecraft designers and operators. After establishing a relative definition for a cabin leak, the paper covers general descriptions of detection equipment, detection methods, and general operational methods for management of a cabin leak. Subsequently, all these items are addressed from the perspective of the Space Shuttle Program, as this will be of the most value to future spacecraft due to similar operating profiles. Emphasis here is placed upon why and how these methods and philosophies have evolved to meet the Space Shuttle s needs. This includes the core ideas of: considerations of maintaining higher cabin pressures vs. lower cabin pressures, the pros and cons of a system designed to feed the leak with gas from pressurized tanks vs. using pressure suits to protect against lower cabin pressures, timeline and consumables constraints, re-entry considerations with leaks of unknown origin, and the impact the International Space Station (ISS) has had to the standard Space Shuttle cabin leak response philosophy. This last item in itself includes: procedural management differences, hardware considerations, additional capabilities due to the presence of the ISS and its resource, and ISS docking/undocking considerations with a

    Full Text Available Paraphrase the title of the famous essay by Herbert Marcuse, since the image has traditionally been generated of man, masculinity, has been one-dimensional. I mean, the man was characterized by traits and behaviors established and entrenched since ancient time, considering all other distinguishing signs as mere deviations from the normative improper. But observe that this undeniable reality, as analyzed various researchers through what has come to be called Men's studies, has proven to be a fallacy difficult to maintain throughout history and today turns into fallacious and ineffective against changes in our current existing corporate models.

  4. Mathematical model of one-man air revitalization system

    Science.gov (United States)

    1976-01-01

    A mathematical model was developed for simulating the steady state performance in electrochemical CO2 concentrators which utilize (NMe4)2 CO3 (aq.) electrolyte. This electrolyte, which accommodates a wide range of air relative humidity, is most suitable for one-man air revitalization systems. The model is based on the solution of coupled nonlinear ordinary differential equations derived from mass transport and rate equations for the processes which take place in the cell. The boundary conditions are obtained by solving the mass and energy transport equations. A shooting method is used to solve the differential equations.

    MILOS RASTOVIC

    2013-05-01

    Full Text Available Nowadays, Marcuse’s main book One-Dimensional Man is almost obsolete, or rather passé. However, there are reasons to renew the reading of his book because of “the crisis of capitalism,” and the prevailing framework of technological domination in “advanced industrial society” in which we live today. “The new forms of control” in “advanced industrial societies” have replaced traditional methods of political and economic administration. The dominant structural element of “advanced industrial society” has become a technical and scientific apparatus of production and distribution of technology and administrative practice based on application of impersonal rules by a hierarchy of associating authorities. Technology has been liberated from the control of particular interests, and it has become the factor of domination in itself. Technological domination stems from the technical development of the productive apparatus that reproduces its ability into all spheres of social life (cultural, political, and economic. Based upon this consideration, in this paper, I will examine Marcuse’s ideas of “the new forms of control,” which creates a one–dimensional society. Marcuse’s fundamental thesis in One-Dimensional Man is that technological rationality is the most dominant factor in an “advanced industrial society,” which unites two earlier opposing forces of dissent: the bourgeoisie and the proletariat.

    Full Text Available This article will discuss the issues at stake when cooperation between library and faculty on information literacy (IL is initiated and explored by using an action research approach. Research on and experiences from cooperation between faculty libraries and faculties indicate that several teaching programmes have not integrated IL into the curriculum nor have they established a formalised cooperation between library and faculty on IL. Participants in the project were three librarians, six lecturers, one library manager, two directors of programme and two project managers from VIA University College, Denmark. The data for this study originates from focus group interviews, process protocols, records of reflective sessions and support meetings as well as from mail correspondences. Results indicate that formal cooperation between librarians and educators is necessary and provides the needed access to the other’s understanding of IL, the curriculum, pedagogical professionalism and mutual roles. A joint conceptual understanding of IL is important for making this teamwork work. Librarians need access to programme documents and knowledge on students’ level of learning and on course work. Co-teaching supports the librarian in developing pedagogical skills. Educators have diverging experiences with IL which can be a problem when challenging students on IL for their assignments. IL is everyone’s business and local dissemination of an agreed curriculum intervention throughout a programme is important. Leadership and re-sources are also significant if the integration of IL is to be possible.

    2008-01-01

    In the past ∼7 years, microwave gyrotron technology has rapidly evolved to a critical threshold wherein ultra-energetic space launch missions based on beamed energy propulsion (BEP) now appear eminently feasible. Over the next 20 years, hundred megawatt-class microwave power-beaming stations could be prototyped on high deserts and 3- to 4 km mountain peaks before migrating into low Earth orbit, along with their passive microwave relay satellites. Described herein is a 20 GW rechargeable nuclear power satellite and microwave power-beaming infrastructure designed for manned space launch operations in the year 2025. The technological readiness of 2500 GJ superconducting magnetic energy storage 'batteries', 433-m ultralight space structures, 100 MW liquid droplet radiators, 1-6+ MW gyrotron sources, and mega-scale arrays (e.g., 3000 phase-locked units) is addressed. Microwave BEP is 'breakthrough' technology with the very real potential to radically reduce space access costs by factors of 100 to 1000 in the forseeable future

    1990-01-01

    This paper aims to ascertain and further develop design guidelines for a man-machine interface compatible with plant operators' problem solving strategies. As the framework for this study, operator's information processing activities were modeled, based on J. Rasmussen's framework for cognitive task analysis. Two experiments were carried out. One was an experiment aimed at gaining an understanding of internal mechanisms involved in mistakes and slips which occurred in operators' responses to incidents and accidents. As a result of fifteen cases of operator performance analysis, sixty one human errors were identified. Further analysis of the errors showed that frequently occurring error mechanisms were absent-mindedness, lack of recognition of patterns in diagnosis and failed procedure formulation due to memory lapses. The other kind of experiment was carried out to identify the envelope of trajectories for the operator's search in the problem space consisting of the two dimensions of means-ends and whole-part relations while dealing with transients. Two cases of experimental sessions were conducted with the thinking-aloud method. From analyses based on verbal protocols, trajectories of operator's search were derived, covering from the whole plant level through the component level in the whole-part dimension and covering from the functional purpose level through the physical form level in the means-ends dimension. The findings obtained from these analyses serve as a basis for developing design guidelines for man-machine interfaces in control rooms of nuclear power plants

    Gershzohn, Gary R.; Sirko, Robert J.; Zimmerman, K.; Jones, A. D.

    1990-01-01

    This task concerns the design, development, testing, and evaluation of a new proximity operations planning and flight guidance display and control system for manned space operations. A forecast, derivative manned maneuvering unit (MMU) was identified as a candidate for the application of a color, highway-in-the-sky display format for the presentation of flight guidance information. A silicon graphics 4D/20-based simulation is being developed to design and test display formats and operations concepts. The simulation includes the following: (1) real-time color graphics generation to provide realistic, dynamic flight guidance displays and control characteristics; (2) real-time graphics generation of spacecraft trajectories; (3) MMU flight dynamics and control characteristics; (4) control algorithms for rotational and translational hand controllers; (5) orbital mechanics effects for rendezvous and chase spacecraft; (6) inclusion of appropriate navigation aids; and (7) measurement of subject performance. The flight planning system under development provides for: (1) selection of appropriate operational modes, including minimum cost, optimum cost, minimum time, and specified ETA; (2) automatic calculation of rendezvous trajectories, en route times, and fuel requirements; (3) and provisions for manual override. Man/machine function allocations in planning and en route flight segments are being evaluated. Planning and en route data are presented on one screen composed of two windows: (1) a map display presenting a view perpendicular to the orbital plane, depicting flight planning trajectory and time data attitude display presenting attitude and course data for use en route; and (2) an attitude display presenting local vertical-local horizontal attitude data superimposed on a highway-in-the-sky or flight channel representation of the flight planned course. Both display formats are presented while the MMU is en route. In addition to these displays, several original display

    Full Text Available The prevailing concept of geography, understood as the study and description of the Earth, can be viewed as a form of removal: less than two-thirds of the globe, that is, the seas or the liquid elements of the Earth, are removed or at the very least are not explicitly designated. This article will focus on issues concerning the classification, systematization, and conceptualization of geographic knowledge that took place in nineteenth-century Germany. I will try to demonstrate how this alleged “removal” operates in modern geography and how it links with a contrasting movement that aims to reintegrate the liquid element of the Earth into the field of geography, on the basis of the man/world relation. I will focus in particular on Friedrich Ratzel’s (1844-1904 pioneering studies in anthropogeography and political geography.

    The operational safety in nuclear power plants depends strongly on man machine interfaces (MMI), such as assignment of equipment on control boards and operation procedures in emergency situations. Therefore, the evaluation and analysis methods for the MMI are important. In order for the methods to be practical, the methods should be executed in each step of design and be easy for designers to use. We aim to develop SEAMAID system: a computer supported system for evaluating and analyzing the MMI by simulating the interaction between the operator and the machine. In this paper, we discuss problems of the conventional methods and the required functions of the operator simulator for the SEAMAID. The operator simulator executes not human errors but correct behavior which follows the operational procedure. The SEAMAID evaluates the MMI by finding potential human errors which could occur in the simulated interactions and points out the problematic interaction parts which could induce human errors. We construct the operator simulator by combining the human model which was proposed by Prof. Reason, and the knowledge base model based on the Petri net model. This simulator can treat frequency parameter which represents the degree of frequency of using a certain knowledge. We conduct two sample simulations in different frequency parameters in the same scenario. These simulation results show that even if the operator behaves correctly following the procedure, there are alternative task sequences. We verify that the simulated interactions are in good agreement with the actual one. Also, we propose the method to point out the problematic parts in the interactions based on the working memory consumption. (author)

    1982-02-18

    Four coal seams, with a total thickness of 16 m, are in production at this opencast mine in the Transvaal; the first coal was mined in 1978. The overburden is stripped by three draglines, and the coal is worked with one shovel and three front-end loaders. Daily production capacity is 28 000 t of coal. The preparation plant has a rated throughput of 1750 t of run-of-mine coal per hour. 5 mt of coal were mined in 1981 and dispatched to Richards Bay, from where the coal is shipped to Western industrial nations. Some 200 million R were invested in the opencast mine, the preparation plant and the infrastructure. Company policy is much concerned with the training and education of the people on the mine; 25% of the personnel attended training courses last year. Pay categories are established in relation to the Peterson evaluation plan; jobs are graded from Group 1 (the lowest) to Group 15 (the grade of the General Manager). The current minimum wage is 214 to 231 R and is well above the living level and the cost of living. The employees live in Company one-family houses, or in bachelor accommodation in the case of unmarried employees. The quality of housing is exactly the same for Blacks and Whites. The housing estates include recreational facilities, sportsfields, a primary school, a clinic, a central restaurant and shops. The present article also gives details of leave entitlements and pensions.

    1984-01-01

    Improvement of the man-machine interface of nuclear power plants is an important contribution to the further enhancement of operational safety. In addition, recent advances in computer technology seem to offer the greatest opportunity to date for achieving improvement in the man-machine interface. The development of a computerized operator support system for BWRs has been undertaken since 1980 with the support of the Japanese Government. The conceptual design of this system is based on the role of the operators. The main functions are standby system management, disturbance analysis and post-trip operational guidance. The objective of the standby system management is to monitor the standby status of the engineered safety feature during normal operation to assure its proper functioning at the onset of emergency situations. The disturbance analysis system detects disturbances in the plant in their early stages and informs the plant operators about, for example, the cause of the disturbances, the plant status and possible propagations. Consequently, operators can take corrective actions to prevent unnecessary plant shutdown. The objective of the post trip operational guide is to support operators in diagnosis and corrective action after a plant trip. Its functions are to monitor the performance of the engineered safety feature, to identify the plant status and to guide the appropriate corrective action to achieve safe plant shutdown. The information from the computerized operator support system is supplied to operators through a colour CRT operator console. The authors have evaluated the performance of various new man-machine interfacing tools and proposed a new operator console design. A prototype system has been developed and verification/validation is proceeding with a BWR plant simulator. (author)

    The Tokyo Electric Power Company (TEPCO) has developed a new Main Control Room design for the Advanced Boiling Water Reactor (ABWR) to improve man-machine interface. New configuration of panels and enhanced automation are some of the features of the ABWR type Main Control Room design. Various technologies such as Cathode Ray Tubes (CRTs) and Flat Displays (FDs) with touch-sensitive operations are contributed to the development of the ABWR type control room design. This design will be first applied to Kashiwazaki-Kariwa Nuclear Power Station unit 6 (K-6). To train the operators sufficiently, TEPCO reviewed the operator training program. Compared with the conventional training, new training menu will be added and the training of ABWR operators will be started 6 months earlier. An ABWR simulator is under construction and training using this simulator is scheduled to be started in August 1994, which is 18 months before fuel loading of K-6. We are reviewing malfunction modes on the simulator. (author)

    1988-01-01

    Nuclear power generation has been steadily developing worldwide and is now playing a very important part in total energy supply. In order to further promote nuclear power generation harmoniously, it is essential to secure the trust of the public by keeping safe and stable operation and to make constant efforts not to repeat such severe accidents as TMI and Chernobyl. These two accidents have caused us to recognize the substantial importance of the Man-Machine interface. With this as a background, the International Conference on the Man-Machine Interface in the Nuclear Industry was held in Tokyo for four days from February 15 th 1988, organized by IAEA and in cooperation with OECD/NEA as well as CEC. I would like to review this conference, for which I was the Vice Chairman of the Japanese Organizing Committee, and to explain my opinion about this issue

    1996-01-01

    Both operating results and human factors studies show that man is able to meet the requirements in this working environment. Hence the degree of human reliability required by the design basis of nuclear power plants is ensured. This means: - Nuclear technology for electricity generation is justifiable from the human factors point of view. - The chief opponent is not right in saying that man is not able to cope with the risks and challenges brought about by nuclear technology applications. The human factors concept for optimisation or configuration of the man-machine systems represents an additional endeavor on the part of nuclear power plant operators within the framework of their responsibilities. Human factors analyses meet with good response by the personnel, as analysis results and clarification of causes of accident scenarios contribute to relieve the personnel (exoneration) and find ways for remedial action.

    A design for a 900-1000 GeV, 100 khz parasitic test beam for use during collider operations has been developed. The beam makes use of two bent crystals, one for extraction and the other one for redirecting the beam in to the present Switchyard beam system. The beam requires only a few modifications in the A0 area and largely uses existing devices. It should be straight-forward to modify one or two beam lines in the fixed target experimental areas to work above 800 GeV. Possibilities for improvements to the design,to operate at higher fluxes are discussed

    Air breathing proton exchange membrane fuel cells (PEMFC) are being considered as a power source for man-portable equipment, such as army radios. In addition to the weight and volume of the fuel cell itself, the device producing hydrogen with which to fuel the cell is also of crucial importance. This paper describes a number of hydrogen storage methods and discusses their applicability to man-portable equipment. (orig.)

    1999-01-01

    One way of ensuring high human reliability is to systematically record, analyse and optimise the identified human factors influencing the safety of operation of NPPs. There are two kinds of human factors to be considered: Those identified and characterised in their actual influence on the man-machine system after an event has happened, and the potential human factors, as far as they are known. The purpose of the paper presented is to: - explain the man-machine interface on the basis of the descriptions delivered by work science, as well as with the information model (acquisition, processing and application of information); - explain their influence on the human performance; - identify the organisational units/competences of a nuclear power plant with respect to responsibility for dealing with those factors influencing human performance; - describe suitable joint action of the responsible organisational units; - present results of HF system reviews and modifications.

    Full Text Available Lisfranc was probably the first to excise the rectum for cancer. He performed operation using perineal approach in 1826. This operation came into common use fifty years later. Czerny did the first combined abdominoperineal resection in attempt to finish excision he could not complete from below. Some fifteen years later Ernest Miles described the planned, one stage abdominoperineal resection.Miles name has become a synonym for this combined procedure, creating a radical change in the philosophy of resection and en bloc lymphadenectomy.In the beginning of twenty-century abdominoperineal resection became golden standard in the treatment of rectal cancer. Reconstructive operations, introduction of stapling devices and better understanding of potential tumor spread, reduced indications for Miles operation.Surgical treatment of rectal cancer made progress in the past 100 years. Miles was the first in line. Without his theory of perirectal lymphatic spread recurrence rate would be still as high as 95%.

    Full Text Available The study covers patristic (primarily Greek comments on the fragment of Gen 3. 22 “And the Lord God said, Behold, the man is become as one of us, to know good and evil”, which can be grouped in three main patterns. The first and the most widespread one (from Justin Martyr to Maximus the Confessor suggests reading Gen 3. 22 as an example of God’s irony employed to show Adam that the serpent’s promise to “be as gods” was false and to urge him to repentance. Armenian and Antiochian versions of this pattern are described with some of its features indicating possible dependence on Pseudo-Clementine tradition. The second pattern was elaborated by the Alexandrian exegetes (Origen and Didymus the Blind and interprets “one of us” as the “one of” the primordial unity of God and intelligible beings, i.e. the devil, who fell away from God and who was followed by Adam. The third pattern was developed in the context of the 4th and 6th Ecumenical councils’ Christological theology (Cyril of Alexandria and Anastasius of Sinai and is based on Christological analogy: “one of us” is God’s Word as the second Hypostasis of Holy Trinity, and Adam’s likeness to God is understood using the fundamental analogy between Christ as the second Adam and the fi rst, old Adam. The reasoning of each of these three patterns was examined to show their internal logic consistency and the difficulties arising when they are externally compared one with another.

    We propose a differential operator for computing the residues associated with a class of meromorphic n-forms that frequently appear in the Cachazo-He-Yuan form of the scattering amplitudes. This differential operator is conjectured to be uniquely determined by the local duality theorem and the intersection number of the divisors in the n-form. We use the operator to evaluate the one-loop integrand of Yang-Mills theory from their generalized CHY formulae. The method can reduce the complexity of the calculation. In addition, the expression for the 1-loop four-point Yang-Mills integrand obtained in our approach has a clear correspondence with the Q-cut results.

The D-2 data processing concept and associated interfaces is presented as well; although this portion of the MSCC facilities is unlikely to be used in later IOI operations activities the experience gathered during D-2 operations will be relevant for defining the Columbus (MSCC - Phase 2) configuration. A summary of the available budget and the allocation to the discussed MSCC Phase-1 facilities will be given. One chapter of the paper will present the current status and objectives of the Detailed Definition Phase (DDP) contract with industry. The last part of this presentation will address the planned implementation integration and test approach for the MSCC as a facility suitable for Columbus operations.

    One of the important activities of ESA Science Operations Centre is to provide Data Analysis Software (DAS) to enable users and scientists to process data further to higher levels. During operations and post-operations, Data Analysis Software (DAS) is fully maintained and updated for new OS and library releases. Nonetheless, once a Mission goes into the "legacy" phase, there are very limited funds and long-term preservation becomes more and more difficult. Building on Virtual Machine (VM), Cloud computing and Software as a Service (SaaS) technologies, this project has aimed at providing long-term preservation of Data Analysis Software for the following missions: - PIA for ISO (1995) - SAS for XMM-Newton (1999) - Hipe for Herschel (2009) - EXIA for EXOSAT (1983) Following goals have guided the architecture: - Support for all operations, post-operations and archive/legacy phases. - Support for local (user's computer) and cloud environments (ESAC-Cloud, Amazon - AWS). - Support for expert users, requiring full capabilities. - Provision of a simple web-based interface. This talk describes the architecture, challenges, results and lessons learnt gathered in this project.

  6. Sample Size of One: Operational Qualitative Analysis in the Classroom

    Full Text Available Qualitative analysis has two extraordinary capabilities: first, finding answers to questions we are too clueless to ask; and second, causal inference – hypothesis testing and assessment – within a single unique context (sample size of one. These capabilities are broadly useful, and they are critically important in village-level civil-military operations. Company commanders need to learn quickly, "What are the problems and possibilities here and now, in this specific village? What happens if we do A, B, and C?" – and that is an ill-defined, one-of-a-kind problem. The U.S. Army's Eighty-Third Civil Affairs Battalion is our "first user" innovation partner in a new project to adapt qualitative research methods to an operational tempo and purpose. Our aim is to develop a simple, low-cost methodology and training program for local civil-military operations conducted by non-specialist conventional forces. Complementary to that, this paper focuses on some essential basics that can be implemented by college professors without significant cost, effort, or disruption.

    Following graduation in 1973 from the Ecole de l'Air (the French Air Force Academy), Michel Tognini served in the French Air Force as an operational fighter pilot, flight leader in 1976, flight commander in 1979, test pilot then chief test pilot from 1983 to 1985. In 1985, France opened a recruitment program to expand its astronaut corps, and Michel Tognini was one of seven candidates selected by CNES. In July 1986, he was one of four candidates to undergo medical examinations in Moscow. In August 1986, he was assigned as a back-up crew member for the Soyuz TM-7 mission. Although he remained a French Air Force officer, he was placed on detachment to CNES for his space flight activities from September 1986 onwards. In 1991 he went to Star City, Russia, to start prime crew training for the third Soviet-French ANTARES mission. During his stay in Russia, he linked up with Mir (ANTARES mission) and spent 14 days (July 27–Aug. 10, 1992; Soyuz TM-14 and TM-14)carrying out a program of joint Soviet-French experimen...

  9. ECCS Operability With One or More Subsystem(s) Inoperable

    2002-01-01

    equivalent to a single Operable ECCS train exists with those components out of service. This evaluation ensures that the safety analysis assumption associated with one train of emergency core cooling system (ECCS) is still preserved by various combinations of components in opposite trains. An ECCS train is inoperable if it is not capable of delivering design flow to the reactor coolant system (RCS). Individual components are inoperable of they are not capable of performing their design function, or support systems are not available. Due to the redundancy of trains and the diversity of subsystems, the inoperability of one component in a train does render the ECCS incapable of performing its function. Neither does the inoperability of two different components, each in a different train, necessarily result in a loss of function for the ECCS. The intent of Condition A is to maintain a combination of components such that 100% of the ECCS flow equivalent to a single Operable ECCS train remains available. This allows increased flexibility in plant operations under circumstances when components in the required subsystem may be inoperable, but the ECCS remains capable of delivering 100% of the required flow equivalent. This paper presents a methodology for identifying the minimum set of components necessary for 100% of the ECCS flow equivalent to a single Operable ECCS train. An example of the implementation of this methodology is provided for a typical Westinghouse 3-loop ECCS design. (authors)

  10. Man-machine supervision

    International Nuclear Information System (INIS)

    Montmain, J.

    2005-01-01

    Today's complexity of systems where man is involved has led to the development of more and more sophisticated information processing systems where decision making has become more and more difficult. The operator task has moved from operation to supervision and the production tool has become indissociable from its numerical instrumentation and control system. The integration of more and more numerous and sophisticated control indicators in the control room does not necessary fulfill the expectations of the operation team. It is preferable to develop cooperative information systems which are real situation understanding aids. The stake is not the automation of operators' cognitive tasks but the supply of a reasoning help. One of the challenges of interactive information systems is the selection, organisation and dynamical display of information. The efficiency of the whole man-machine system depends on the communication interface efficiency. This article presents the principles and specificities of man-machine supervision systems: 1 - principle: operator's role in control room, operator and automation, monitoring and diagnosis, characteristics of useful models for supervision; 2 - qualitative reasoning: origin, trends, evolutions; 3 - causal reasoning: causality, causal graph representation, causal and diagnostic graph; 4 - multi-points of view reasoning: multi flow modeling method, Sagace method; 5 - approximate reasoning: the symbolic numerical interface, the multi-criteria decision; 6 - example of application: supervision in a spent-fuel reprocessing facility.

    The Experiment Computer Operating System (ECOS) of the Spacelab will allow the onboard Payload Specialist to command experiment devices and display information relative to the performance of experiments. Three candidate ECOS command and control service concepts were reviewed and laboratory data on operator performance was taken for each concept. The command and control service concepts evaluated included a dedicated operator's menu display from which all command inputs were issued, a dedicated command key concept with which command inputs could be issued from any display, and a multi-display concept in which command inputs were issued from several dedicated function displays. Advantages and disadvantages are discussed in terms of training, operational errors, task performance time, and subjective comments of system operators.

    The Meteo Hydrological Functional Center for Civil Protection of the Environmental Protection Agency of the Liguria Region is responsible for issuing forecasts primarily aimed at the Civil Protection needs. Several deterministic high resolution models, run every 6 or 12 h, are regularly used in the Center to elaborate weather forecasts at short to medium range. The Region is frequently affected by severe flash floods over its very small basins, characterized by a steep orography close to the sea. These conditions led the Center in the past years to pay particular attention to the use and development of high resolution model chains for explicit simulation of convective phenomena. For years, the availability of several models has been used by the forecasters for subjective analyses of the potential evolution of the atmosphere and of its uncertainty. More recently, an Interactive Poor Man's Ensemble has been developed, aimed at providing statistical ensemble variables to help forecaster's evaluations. In this paper the structure of this system is described and results are validated using the regional dense ground observational network.

  14. One-loop potential with scale invariance and effective operators

    CERN Document Server

    Ghilencea, D M

    2016-01-01

    We study quantum corrections to the scalar potential in classically scale invariant theories, using a manifestly scale invariant regularization. To this purpose, the subtraction scale $\\mu$ of the dimensional regularization is generated after spontaneous scale symmetry breaking, from a subtraction function of the fields, $\\mu(\\phi,\\sigma)$. This function is then uniquely determined from general principles showing that it depends on the dilaton only, with $\\mu(\\sigma)\\sim \\sigma$. The result is a scale invariant one-loop potential $U$ for a higgs field $\\phi$ and dilaton $\\sigma$ that contains an additional {\\it finite} quantum correction $\\Delta U(\\phi,\\sigma)$, beyond the Coleman Weinberg term. $\\Delta U$ contains new, non-polynomial effective operators like $\\phi^6/\\sigma^2$ whose quantum origin is explained. A flat direction is maintained at the quantum level, the model has vanishing vacuum energy and the one-loop correction to the mass of $\\phi$ remains small without tuning (of its self-coupling, etc) bey...

    Several operator information systems for nuclear plants have been developed at Reactor Control Division of BARC and these have involved extensive operator interaction to extract the maximum information from the systems. Each of these systems used a different scheme for operator interaction. A composite package has now been developed on PC/AT with EGA/VGA for use with any system to obviate the necessity to develop new software for each project. This permits information to be displayed in various formats viz. trend and history curves, tabular data, bar graphs and core matrix (both for 235 and 500 MWe cores). It also allows data to be printed and plotted using multi colour plotter. This package thus integrates all the features of the earlier systems. It also integrates the operator interaction scheme. It uses window based pull down menus to select parameters to be fed into a particular display format. Within any display format the operator has significant flexibility to modify the selected parameters using context dependent soft keys. The package also allows data to be retrieved in machine readable form. This report describes the various user friendly functions implemented and also the design of the system software.

    Full Text Available Ports working in a network-community that is composed of a group of associative enterprises and logistic chains require managing their strategic and operational knowledge for achieving the efficiency of their activities at both levels. A conceptual model is presented that allows the development of a strategy for a port community through a strategic planning approach using operational knowledge. The different actors that participate in the community, their roles, and the main processes in which they participate are characterized. Then the vision and the mission of the community, and the strategic objectives in the four perspectives of the Balanced Scorecard: financial, clients, processes, and learning and growth, are defined. Finally, a set of indicators oriented toward the knowledge management of the main actors participating in the community is designed.

    @@ Whether shopping casually or searching for some obscure, hard to find item, more and more Chinese are logging online and turning to customer-to-customer (C2C) network operators for their trading needs rather than bother with the hassles of conventional buying and selling. Proof is in the numbers.

    MSCs are known as multipotent mesenchymal stem cells that have been found capable of differentiating into various lineages including cartilage. However, recent studies suggest MSCs are pericytes that stimulate tissue repair through trophic signaling. Aimed at articular cartilage repair in a one-stage cell transplantation, this study provides first clinical evidence that MSCs stimulate autologous cartilage repair in the knee without engrafting in the host tissue. A phase I (first-in-man) clinical trial studied the one-stage application of allogeneic MSCs mixed with 10% or 20% recycled defect derived autologous chondrons for the treatment of cartilage defects in 35 patients. No treatment-related serious adverse events were found and statistically significant improvement in clinical outcome shown. Magnetic resonance imaging and second-look arthroscopies showed consistent newly formed cartilage tissue. A biopsy taken from the center of the repair tissue was found to have hyaline-like features with a high concentration of proteoglycans and type II collagen. DNA short tandem repeat analysis delivered unique proof that the regenerated tissue contained patient-DNA only. These findings support the hypothesis that allogeneic MSCs stimulate a regenerative host response. This first-in-man trial supports a paradigm shift in which MSCs are applied as augmentations or "signaling cells" rather than differentiating stem cells and opens doors for other applications.

    Full Text Available We study how two pieces of localized quantum information can be delocalized across a composite Hilbert space when a global unitary operation is applied. We classify the delocalization power of global unitary operations on quantum information by investigating the possibility of relocalizing one piece of the quantum information without using any global quantum resource. We show that one-piece relocalization is possible if and only if the global unitary operation is local unitary equivalent of a controlled-unitary operation. The delocalization power turns out to reveal different aspect of the non-local properties of global unitary operations characterized by their entangling power.

    Experience of pain associated with both chronic as well as acute medical conditions is a main cause for call for ambulance. The aim of this study was to establish both frequency and characteristics of pain reported by patients treated in pre-hospital environment in a single operational area. The supplementary goal was an analysis of methods of pain alleviation applied by medical personnel in the above described scenario. The written documentation of 6 months of year 2009 provided by doctor-manned as well as paramedic-only ambulances operating in Tatra county, Małopolska, Poland was analyzed. Medical personnel inquired about pain experienced in 57.4% of cases, 10-point numerical rating scale was used in 22.3% of patients. Pain was reported by 43.8% of patients, the most frequent reasons of experienced pain were trauma and cardiovascular diseases. In almost half of the cases pain was referred to the areas of chest and abdomen. Non-traumatic pain was reported by 47.7% of patients, post-traumatic in 41.3% of cases, 11% of subjects reported ischemic chest pain. 42.3% of pain-reporting patients received some form of analgesia, yet only 3% of subjects in this group received opiates. Personnel of paramedic-only ambulances tended to use pain intensity scale more often (P < 0.01), yet administered pain alleviating drugs noticeably less often than the doctor-manned teams (P < 0.01). The use of pain alleviating drugs, opiates especially, was inadequate in proportion to frequency and intensity of pain reported by patients. General, nation-wide standards of pain measurement and treatment in pre-hospital rescue are suggested as a means to improve the efficacy of pain reduction treatment.

    'One Man Can' (OMC) is a rights-based gender equality and health programme implemented by Sonke Gender Justice in South Africa. It has been featured as an example of best practice by the World Health Organization, UNAIDS, and the UN Population Fund, and translated into nearly a dozen languages and implemented all across Africa. South Africa has strong gender and HIV-related policies, but the highest documented level of men's violence against women in the world, and the largest number of people living with HIV. In this context, OMC seeks to improve men's relationships with their partners, children, and families, reduce the spread and impact of HIV and AIDS, and reduce violence against women, men, and children. To understand whether and how OMC workshops brought about changes in men's attitudes and practices related to parenting, an academic-non-government organisation partnership was carried out with the University of California at San Francisco, the University of Cape Town, and Sonke. The workshops appear to have contributed powerfully to improved parenting and more involved and responsible fathering. This article shares our findings in more detail and discusses the promises and challenges of gender-transformative work with men, underscoring the implications of this work for the health and well-being of women, children, and men.

  13. Classification and Construction of Invertible Linear Differential Operators on a One-Dimensional Manifold

    Directory of Open Access Journals (Sweden)

    V. N. Chetverikov

    2014-01-01

    Full Text Available Invertible linear differential operators with one independent variable are investigated. The problem of description of such operators is important, because it is connected with transformations and the classification of control systems, in particular, with the flatness problem.Each invertible linear differential operator represents a square matrix of scalar differential operators. Its product with an operator-column is an operator-column whose order does not exceed the sum of orders of initial operators. The operators-columns, the product with which leads to order fall, i.e. the order of the product is less than sum of orders of factors, are interesting for the description of invertible operators. In this paper the classification of invertible operators is based on dimensions dk,p of intersections of modules Gp and Fk for various k and p, where Gp is the module of all operators-columns of order not above p, and Fk is the module of compositions of the invertible operator with all operators-columns of order not above k. The invertible operators that have identical sets of numbers dk,p form one class.In the paper the general properties of tables of numbers dk,p for invertible operators are investigated. A correspondence between invertible operators and elementary-geometrical models which in the paper are named by d-schemes of squares is constructed. The invertible operator is ambiguously defined by its d-scheme of squares. The mathematical structure that must be set for its unique definition and an algorithm for the construction of the invertible operator are offered.In the proof of the main result, methods of the theory of chain complexes and their spectral sequences are used. In the paper all necessary concepts of this theory are formulated and the corresponding facts are proved.Results of the paper can be used for solving problems in which invertible linear differential operators are arisen. Namely, it is necessary to formulate the conditions on

  19. Operator algebras for general one-dimensional quantum mechanical potentials with discrete spectrum

    International Nuclear Information System (INIS)

    Wuensche, Alfred

    2002-01-01

    We define general lowering and raising operators of the eigenstates for one-dimensional quantum mechanical potential problems leading to discrete energy spectra and investigate their associative algebra. The Hamilton operator is quadratic in these lowering and raising operators and corresponding representations of operators for action and angle are found. The normally ordered representation of general operators using combinatorial elements such as partitions is derived. The introduction of generalized coherent states is discussed. Linear laws for the spacing of the energy eigenvalues lead to the Heisenberg-Weyl group and general quadratic laws of level spacing to unitary irreducible representations of the Lie group SU(1, 1) that is considered in detail together with a limiting transition from this group to the Heisenberg-Weyl group. The relation of the approach to quantum deformations is discussed. In two appendices, the classical and quantum mechanical treatment of the squared tangent potential is presented as a special case of a system with quadratic level spacing

  5. One-Loop Operation of Primary Heat Transport System in MONJU During Heat Transport System Modifications

    International Nuclear Information System (INIS)

    Goto, T.; Tsushima, H.; Sakurai, N.; Jo, T.

    2006-01-01

    MONJU is a prototype fast breeder reactor (FBR). Modification work commenced in March 2005. Since June 2004, MONJU has changed to one-loop operation of the primary heat transport system (PHTS) with all of the secondary heat transport systems (SHTS) drained of sodium. The purposes of this change are to shorten the modification period and to reduce the cost incurred for circuit trace heating electrical consumption. Before changing condition, the following issues were investigated to show that this mode of operation was possible. The heat loss from the reactor vessel and the single primary loop must exceed the decay heat by an acceptable margin but the capacity of pre-heaters to keep the sodium within the primary vessel at about 200 deg. C must be maintained. With regard to the heat loss and the decay heat, the estimated heat loss in the primary system was in the range of 90-170 kW in one-loop operation, and the calculated decay heat was 21.2 kW. Although the heat input of the primary pump was considered, it was clear that circuit heat loss greatly exceeded the decay heat. As for pre-heaters, effective capacity was less than the heat loss. Therefore, the temperature of the reactor vessel room was raised to reduce the heat loss. One-loop operation of the PHTS was able to be executed by means of these measures. The cost of electrical consumption in the power plant has been reduced by one-loop operation of the PHTS and the modification period was shortened. (authors)

It is known that to the formal operator H(lambda, ..mu..) may be associated a selfadjoint operator H(lambda, ..mu..) on L/sup 2/(R). If q is of finite range, for lambda < 0 and /..mu../ is small enough, we prove that H(lambda,..mu..) has an antibound state; that is the resolvent of H(lambda,..mu..) has a pole on the negative real axis on the second Riemann sheet.

    We propose the general scheme of remote one-qubit information concentration. To achieve the task, the Bell-correlated mixed states are exploited. In addition, the nonremote one-qubit information concentration is equivalent to the decoding of the quantum error-correction code. Here we propose how to decode the stabilizer codes. In particular, the proposed scheme can be used for the operator quantum error-correction codes. The encoded state can be recreated on the errorless qubit, regardless how many bit-flip errors and phase-flip errors have occurred

  11. A new tool for man/machine integration

    International Nuclear Information System (INIS)

    Sommer, W.C.

    1981-01-01

    A popular term within the nuclear power industry today, as a result of TMI, is man/machine interface. It has been determined that greater acknowledgement of this interface is necessary within the industry to integrate the design and operational aspects of a system. What is required is an operational tool that can be used early in the engineering stages of a project and passed on later in time to those who will be responsible to operate that particular system. This paper discusses one such fundamental operations tool that is applied to a process system, its display devices, and its operator actions in a methodical fashion to integrate the machine for man's understanding and proper use. This new tool, referred to as an Operational Schematic, is shown and described. Briefly, it unites, in one location, the important operational display devices with the system process devices. A man can now see the beginning and end of each information and control loop to better understand its function within the system. A method is presented whereby in designing for operability, the schematic is utilized in three phases. The method results in two basic documents, one describes ''what'' is to be operated and the other ''how'' it is to be operated. This integration concept has now considered the hardware spectrum from sensor-to-display and operated the display (on paper) to confirm its operability. Now that the design aspects are complete, the later-in-time operational aspects need to be addressed for the man using the process system. Training personnel in operating and testing the process system is as important as the original design. To accomplish these activities, documents are prepared to instruct personnel how to operate (and test) the system under a variety of circumstances

    In the poem "Always", the author Pablo Neruda employs the first person narration to incisively reveal the paradoxical traits in human nature by exploring man in relation to love. "I" play a role shifting from a calm narrator to a furious one, and the last recovering to a mild one, which offers a multiple visual angle to observe humanity. In sum, by means of continuous changes of my inner feelings in the poem, Pablo Neruda reveals the paradoxical humanity .

    Full Text Available We study the asymptotic behavior of solutions, in particular the scattering theory, for the nonlinear Schr"{o}dinger equations with cubic and quadratic nonlinearities in one or two space dimensions. The nonlinearities are summation of gauge invariant term and non-gauge invariant terms. The scattering problem of these equations belongs to the long range case. We prove the existence of the modified wave operators to those equations for small final data. Our result is an improvement of the previous work [13

    This paper introduces a simple alternating-current (AC) control strategy to perform quantum state manipulations under non-Markovian noise. A genetic algorithm is adopted to optimize the parameters of the AC control, which can be further used to fulfil one-qubit quantum operations at a given final time. Theoretical analysis and simulations show that our method works almost equally well for 1/f noise, ohmic, sub-ohmic and super-ohmic noise, which demonstrates the robustness of our strategy for noise with various spectra. In comparison with the Markovian cases, our method is more suitable to be used to suppress non-Markovian noise.

    In this report we summarize an extension of Fourier analysis for the solution of the wave equation with a non-constant coefficient corresponding to an inhomogeneous medium. The underlying physics of the problem is exploited to link pseudodifferential operators and phase space path integrals to obtain a marching algorithm that incorporates the backward scattering into the evolution of the wave. This allows us to successfully apply single-sweep, one-way marching methods in inherently two-way environments, which was not achieved before through other methods for this problem.

    In any complex system, the interesting problems occur at the interface of dissimilar subsystems. Control of the Mirror Fusion Test Facility (MFTF) begins with the US Congress, which controls the dollars, which control the people, who control the nine top-level minicomputers, which control the 65 microprocessors, which control the hardware that controls the physics experiment. There are many interesting boundaries across which control must pass, and the one that this paper addresses is the man-machine one. For the MFTF, the man-machine interface consists of a system of seven control consoles, each allowing one operator to communicate with one minicomputer. These consoles are arranged in a hierarchical manner, and both hardware and software were designed in a top-down fashion.

Furthermore, the DWC has tried and succeeded arranging R and D proposals for further improvement in water chemistry control through roadmap planning. In the paper, major achievements in plant technologies and in basic research studies of water chemistry in Japan are reviewed. The contributions of the DWC to the long-term safe management of the damaged reactors at the Fukushima Daiichi Nuclear Power Plant until their decommissioning are introduced. (author)

    2018-03-01

    Recently, Grabowska and Kaplan constructed a four-dimensional lattice formulation of chiral gauge theories on the basis of the chiral overlap operator. At least in the tree-level approximation, the left-handed fermion is coupled only to the original gauge field A, while the right-handed one is coupled only to the gauge field A*, a deformation of A by the gradient flow with infinite flow time. In this paper, we study the fermion one-loop effective action in their formulation. We show that the continuum limit of this effective action contains local interaction terms between A and A*, even if the anomaly cancellation condition is met. These non-vanishing terms would lead an undesired perturbative spectrum in the formulation.

    The Primary cooling system (PCS) of a research reactor is designed to provide adequate cooling to the reactor core with a reasonable margin during all operation modes. The PCS consists of pumps, heat exchangers, and all necessary interconnecting pipes, valves, and instruments. The number of pumps is determined from a safety and economic point of view. As the number of pump trains increase, the cost increases according to the increase in safety class equipment. However, it is impossible to install one pump for a PCS because a zero flow can instantaneously occur during a pump failure such as a pump seizure. Thus, a PCS frequently consists of two parallel 50% capacity pumps and heat exchangers. In addition, check valves are generally installed to prevent a reversal flow when multiple pumps are designed to operate. However, if a swing type check valve is used, it should be estimated whether the slam due to instantaneous closing of the valve affects the system vibration. To reduce the vibration by a slam phenomenon, additional equipment such as a damper will be installed in the valve. The purpose of the check valve in PCS is to prevent the flow path when a reverse flow occurs. The installation of additional equipment will make it difficult to perform this function. In this study, it is estimated whether the PCS can operate without check valves. First, a flow analysis using Flowmaster was compared and verified by the calculation employing a empirical correlation. Second, the simulation for a one pump failure accident was performed and analyzed.

    Full Text Available The experience acquired from more than ten years of operation of an Antarctic geomagnetic observatory is described
    along with the development of data transmission facilities. The observatory was deployed at the Spanish Antarctic
    Station in 1996. The main instrument was an Overhauser magnetometer deployed in dual axis Helmholtz coils, a
    δD/δI configuration. The site is only manned during the summer, with the magnetometer left recording throughout
    the rest of the year. During the 2007-2008 survey the observatory instrumentation has been upgraded with a DMI
    suspended triaxial fluxgate magnetometer, new sampling hardware and data logging software. Both sampling and
    timing are carried out under the control of a PIC based microcontroller and GPS receiver. Data presentation, transmission
    and archiving are performed under the control of a low power embedded PC. For real time access to the data
    two options have been provided and rigorously tested during the last 10 years: METEOSAT and GOES Data Collection
    Systems, and recently, a high frequency (HF digital radio-link, using ionospheric propagation between
    Antarctica and Spain, has been developed. This latest transmission system is being continuously upgraded, and it
    would be possible to extend its application to other remote stations. Measurements have been made during the last
    four years in order to determine the channel characteristics and its variability, mainly the multipath and Doppler
    spread and the link availability for a given SNR in the receiver. These measurements are being used to design the
    physical layer of a radiomodem intended to maximize the link capacity keeping the emitted power low.

The report describes a layout with a spiral ramp as access to the deposition area and with a single operational area above ground. The ramp will be used as a transport route for heavy and bulky transports. A shaft, that connects the operational area with the central area of the deposition area, is used for utility systems and for staff transports between the surface and the deposition area. It has been assumed that the deposition areas and the central area are on the same level. The appendix, describing a two level alternative, shows how the underground area could be arranged if the deposition area for regular operation were to be divided into two levels. The facility description concentrates on the situation during regular operation. It also describes the gradual expansion programme, including land requirements and connections to existing infrastructure. The report concludes with some perspective sketches, which give a vision of how the repository might look when ready for operation. This facility description is a translation of the Swedish SKB report R-02-18. It is important to note that the report gives an example of one possible design for the deep repository. Many issues concerning system design, functional solutions, layout and design ought to be investigated further before deciding on the final design.

    In August 1975, Lawrence Livermore Laboratory began to quantitatively fit all employees who are or may be required to wear any type of full-face respirator. After one year, 306 employees have been fitted. A total of 1362 tests were made, using seven makes of full-face respirators. Of the 306 employees fitted, 284 were tested using more than one make of full-face mask. All employees fitted could get a maximum use limit (MUL) of at least 100, 8 percent has a MUL of 100 to 499 on at least one of the makes of masks tested, 11 percent had an MUL of 500 to 999, 13 percent had an MUL of 1000 to 1999, 24 percent had an MUL of 2000 to 4999, and 44 percent had an MUL greater than 5000. These numbers were derived using the average of the peak leakages occurring during each of six exercises performed while wearing each mask. If the overall average leakage occurring during the six exercises rather than the peak average is used in the calculations, 90 percent of the employees could obtain an MUL over 1000 on at least one make of mask

    Fresh-cut produce is at greater risk of Salmonella contamination. Detection and early warning systems play an important role in reducing the dissemination of contaminated products. One-step Reverse Transcription Polymerase Chain Reaction (RT-qPCR) targeting Salmonella tmRNA with or without a 6-h enrichment was evaluated for the detection of Salmonella in fresh-cut vegetables after 6-h storage. LOD of one-step RT-qPCR was 1·0 CFU per ml (about 100 copies tmRNA per ml) by assessed 10-fold serially diluted RNA from 10 6 CFU per ml bacteria culture. Then, one-step RT-qPCR assay was applied to detect viable Salmonella cells in 14 fresh-cut vegetables after 6-h storage. Without enrichment, this assay could detect 10 CFU per g for fresh-cut lettuce, cilantro, spinach, cabbage, Chinese cabbage and bell pepper, and 10 2 CFU per g for other vegetables. With a 6-h enrichment, this assay could detect 10 CFU per g for all fresh-cut vegetables used in this study. Moreover, this assay was able to discriminate viable cells from dead cells. This rapid detection assay may provide potential processing control and early warning method in fresh-cut vegetable processing to strengthen food safety assurance. Significance and Impact of the Study: Fresh-cut produce is at greater risk of Salmonella contamination. Rapid detection methods play an important role in reducing the dissemination of contaminated products. One-step RT-qPCR assay used in this study could detect 10 CFU per g Salmonella for 14 fresh-cut vegetables with a 6-h short enrichment. Moreover, this assay was able to discriminate viable cells from dead cells. This rapid detection assay may provide potential processing control and early warning method in fresh-cut vegetable processing to strengthen food safety assurance. © 2018 The Society for Applied Microbiology.

    Enteropathogenic, enterotoxigenic and enteroaggregative Escherichia coli (EPEC, ETEC, EAEC) are among the most frequent causes of diarrhoea during travel or on military deployments. Cost-efficient and reliable real-time multiplex PCR (mPCR) assays are desirable for surveillance or point prevalence studies in remote and resource-limited tropical settings. We compared one commercial PCR kit and two in-house assays without using a gold standard to estimate sensitivity and specificity of each assay. Residual materials from nucleic acid extractions of stool samples from two groups with presumably different prevalences and increased likelihood of being infected or colonised by diarrhoeagenic E. coli were included in the assessment. One group comprised samples from returnees from tropical deployments, the second group was of migrants and study participants from high-endemicity settings. Each sample was assessed with all of the PCR assays. Cycle threshold (Ct) values were descriptively compared. The calculated sensitivities for the commercial test vs. the in-house tests were for EPEC 0.84 vs. 0.89 and 0.96, for ETEC 0.83 vs. 0.76 and 0.61, and for EAEC 0.69 vs. 0.54 and 0.69. False positive results were rare - specificity was 0.94 and 0.97 for two EPEC tests and 1.0 for all other tests. Most positive samples had late Ct values corresponding to low quantities of pathogens. Discordant test results were associated with late Ct values. As commercial and in-house assays showed comparable results, in-house tests can be assumed to be safe while affording considerable savings, making them a valuable alternative for surveillance testing in resource-limited tropical areas. © 2017 John Wiley & Sons Ltd.

    Our aim is to present the first year of operation of a Clinical Psychology service in a Primary Care setting. A descriptive study was performed by analysing the requests and the care intervention of the Psychology Service, in collaboration with 36 general practitioners (33% of the staff), belonging to 6 health centres. Within the one year period, 171 outpatients from 15 years and older were referred with mild psychological disorders (> 61 in the global assessment functioning scale, APA, 2002). A total of 111 outpatients received psychological care. The main diagnoses were adaptation disorder, affective disorder, and anxiety. More than half (54.82%) of them achieved a full recovery. After a year follow up, a drop of 25.19% was observed in medicines use. The Primary Care Psychology team is a halfway unit between Primary Care practitioners and specialised units in order to deal with mild mental symptomatology which otherwise could be undertreated. It represents an important support for practitioners. Secondly, the early intervention can prevent mental problems becoming chronic, as shown by the drop in medication use. In spite of the not very high agreement between the practitioner's diagnoses and those made by the Psychology unit, it has set up an important means of communication and with direct and immediate interdisciplinary action. This should eventually lead to savings in economic resources and human suffering. Copyright © 2014. Publicado por Elsevier España, S.L.U.

  18. A new program for calculating matrix elements of one-particle operators in jj-coupling

    1978-01-01

    The aim of this paper is to calculate the matrix elements of one-particle tensor operators occurring in atomic and nuclear theory between configuration state functions representing states containing any number of open shells in jj-coupling. The program calculates the angular part of these matrix elements. The program is essentially a new version of RDMEJJ, written by J.J. Chang. The aims of this version are to eliminate inconsistencies from RDMEJJ, to modify its input requirements for consistency with MCP75, and to modify its output so that it can be stored in a discfile for access by other compatible programs. The program assumes that the configurational states are built from a common orthonormal set of basis orbitals. The number of electrons in a shell having j>=9/2 is restricted to be not greater than 2 by the available CFP routines . The present version allows up to 40 orbitals and 50 configurational states with <=10 open shells; these numbers can be changed by recompiling with modified COMMON/DIMENSION statements. The user should ensure that the CPC library subprograms AAGD, ACRI incorporate all current updates and have been converted to use double precision floating point arithmetic. (Auth.)

    End of life of a floating production, storage and off-loading (FPSO) facility requires a lot of planning and management. One of the major challenges is the issue of decontamination and waste management. Waste disposal is a very sensitive subject and with agreements like the London Protocol and differences in legislation between countries, it has the potential to become a major stumbling block. Radiation safety is something not often on the mind of an FPSO operator. The planning and layout of such a vessel and its processing plant have usually not gone through any as low as reasonably achievable process during design. Planning the decontamination of such a vessel should start long before the actual decommissioning date. Performing regular vessel clean-outs and radiological profiling of the plant can be beneficial in the end. Finding a workable solution in getting naturally occurring radioactive material contaminated waste out of the vessels and tanks and effectively reducing the waste volumes for end of life clean-up is very important.

    Two recent piloted simulation experiments have investigated advanced display concepts applied to civil transport helicopter terminal area operations. Civil Category A helicopter operations apply to multi-engine helicopters wherein a safe recovery (land or fly out) is required in the event of a single engine failure. The investigation used the NASA Ames Research Center Vertical Motion Simulator, which has a full six degrees of freedom, to simulate the flight task as closely as possible. The goal of these experiments was to use advanced cockpit displays to improve flight safety and enhance the mission performance of Category A terminal area operations in confined areas. The first experiment investigated the use of military display formats to assist civil rotorcraft in performing a Category A takeoff in confined terminal areas. Specifically, it addressed how well a difficult hovering backup path could be followed using conventional instruments in comparison to panel mounted integrated displays. The hovering backup takeoff, which enables pilots to land back to the confined area pad in the event of an engine failure, was chosen since it is a difficult task to perform. Seven NASA and Army test pilots participated in the experiment. Evaluations, based on task performance and pilot workload, showed that an integrated display enabled the pilot to consistently achieve adequate or desired performance with reasonable pilot workload. Use of conventional instruments, however, frequently resulted in unacceptable performance (poor flight path tracking), higher pilot workload, and poor situational awareness. Although OEI landbacks were considered a visual task, the improved performance on the backup portion, in conjunction with increased situational awareness resulting from use of integrated displays, enabled the pilots to handle an engine failure and land back safely. In contrast, use of conventional instruments frequently led to excessive rates of sink at touchdown. A second

    Full Text Available Considering Louis Althusser’s inquiries into the function of ideology in sustaining power, the writers of this article discuss the operation of ideological and repressive apparatuses in the asylum Ken Kesey portrays in One Flew over the Cuckoo’s Nest (1962. The novel recounts the story of a group of people contained in an institution that is supposed to treat their allegedly mental problems, whereas under the facade of psychiatric treatment lies a ruthless controlling system whose major purpose is to turn the inmates into obedient, submissive “subjects”. The agents of the institution preserve the patients’ docility through strict rules besides the so-called mental therapy that actually results in more confusion in inmates who consequently lose their self-consciousness and self-confidence. But since every ideological system, besides inducing docile “subjects,” raises a sort of resistance among them, gradually resisting forces are formed in the asylum of the novel by the coming of a new inmate who defies the dominant ideology of the institution. By his jovial, life-affirming ideology, he breathes new life into others, makes them think and believe in themselves and trust each other, and thereby acts as a source of inspiration for several inmates, specially the Indian American narrator of the novel that subsequently challenges his schizophrenia, and finally, when his friend is shocked by electrical devices as the result of which he totally loses his consciousness, smashes the control panel of the ward to escape from that penitentiary.

NIBB allows for smaller treatment volumes while maintaining optimal target coverage. Considering the real-time image-guidance and immobilization provided by the NIBB modality, minimal margins around the target tissue are necessary. Accelerated Partial Breast Irradiation in brachytherapy: is shorter better? - Dorin Todor, PhD VCU A review of balloon and strut devices will be provided together with the origins of APBI: the interstitial multi-catheter implant. A dosimetric and radiobiological perspective will help point out the evolution in breast brachytherapy, both in terms of devices and the protocols/clinical trials under which these devices are used. Improvements in imaging, delivery modalities and convenience are among the factors driving the ultrashort fractionation schedules but our understanding of both local control and toxicities associated with various treatments is lagging. A comparison between various schedules, from a radiobiological perspective, will be given together with a critical analysis of the issues. to review and understand the evolution and development of APBI using brachytherapy methods to understand the basis and limitations of radio-biological ‘equivalence’ between fractionation schedules to review commonly used and proposed fractionation schedules Intra-operative breast brachytherapy: Is one stop shopping best?- Bruce Libby, PhD.

    A numerical study is done to understand the possible operating regimes of RF-ICP torch (3 MHz, 50 kW) using different gases for plasma formation at atmospheric pressure. A two dimensional numerical simulation of RF-ICP torch using argon, nitrogen, oxygen, and air as plasma gas has been investigated using computational fluid dynamic (CFD) software fluent (c) . The operating parameters varied here are central gas flow, sheath gas flow, RF-power dissipated in plasma, and plasma gas. The temperature contours, flow field, axial, and radial velocity profiles were investigated under different operating conditions. The plasma resistance, inductance of the torch, and the heat distribution for various plasma gases have also been investigated. The plasma impedance of ICP torch varies with different operating parameters and plays an important role for RF oscillator design and power coupling. These studies will be useful to decide the design criteria for ICP torches required for different material processing applications.

    In this paper we define a one-dimensional discrete Dirac operator on Z . We study the eigenvalues of the Dirac operator with a complex potential. We obtain bounds on the total number of eigenvalues in the case where V decays exponentially at infinity. We also estimate the number of eigenvalues for the discrete Schrödinger operator with complex potential on Z . That is we extend the result obtained by Hulko (Bull Math Sci, to appear) to the whole Z.

    We describe the modeling and reasoning about operations constraints in an automated mission planning system for an earth observing satellite - EO-1. We first discuss the large number of elements that can be naturally represented in an expressive planning and scheduling framework. We then describe a number of constraints that challenge the current state of the art in automated planning systems and discuss how we modeled these constraints as well as discuss tradeoffs in representation versus efficiency. Finally we describe the challenges in efficiently generating operations plans for this mission. These discussions involve lessons learned from an operations model that has been in use since Fall 2004 (called R4) as well as a newer more accurate operations model operational since June 2009 (called R5). We present analysis of the R5 software documenting a significant (greater than 50%) increase in the number of weekly observations scheduled by the EO-1 mission. We also show that the R5 mission planning system produces schedules within 15% of an upper bound on optimal schedules. This operational enhancement has created value of millions of dollars US over the projected remaining lifetime of the EO-1 mission.

    1976-01-01

    The operating manual is one of many technical documents which the nuclear power plant operator needs for ensuring safe operation. For the operating staff, however, there is only one document, namely the operating manual. The operating manual is an essential element in bringing man and machine in harmony. This is necessary for safe and, as far as possible, uninterrupted operation of the power plant. The operating manual is the only document containing binding instructions for plant operation. All the tasks of plant operation which are carried out by plant staff are described in the operating manual in a form which is as clear and comprehensible as possible. A considerable number of these tasks can only be carried out by man, namely: 1) tasks concerning operational organization, 2) all non-automated areas of plant operation. (orig./TK) [de

    Nuclear power is accepted as a reality in this description of the nature of radioactivity, its presence in the operation of a nuclear reactor, how and why some of the radioactivity is introduced into the environment in a controlled manner, and how these processes should be judged. The didactic approach makes the account an informative one rather than argumentative. The basic properties of radioactivity and its interaction with matter are described in the first chapter. Subsequent chapters deal with the radiation background, radiation and man, nuclear reactors and their fuel cycles, radioactive wastes and the public, environmental behavior and effects, and the acceptability of future discharges. 10 references, 41 figures, 57 tables.

    Full Text Available Contemporary authors emphasise the importance of viewing the family as a specific educational context and of studying its role in the cognitive development. In this paper, we tested the model that postulates the way in which the different ways of parental mediation and various means of the family cultural-supportive system affect the development of formal operations. We assumed that the education of parents and financial status of the family form a wider context that influences the general dimensions of family interaction (emotional exchange and democratism, but also the cultural-pedagogical status of the family, and that their connection with formal operations is mediated by the above-mentioned variables. We expected the education of parents and general dimensions of family interaction to influence the parental mediation characteristic for the development of formal operations, operationalised by CSS scale, and to mediate, via this variable, the development of that form of thinking. The direct link with formal operations is postulated in the case of variables of cultural-pedagogical status and CSS scale. The sample consists of 305 pupils aged 15 to 19. The Structural Equation Modeling was used for testing the postulated model. The results show that there is a direct influence of cultural-pedagogical status and CSS scale on formal operations, but of mother's education as well. Some relations between other predictors were confirmed, and some not, which suggests that the proposed explanatory model must be revised to some degree.

    Since August 1991 the superconducting cw-electron accelerator S-DALINAC at Darmstadt has produced single and multi pass beam which is used for different experiments. At energies below 10 MeV investigations of channeling radiation production and nuclear resonance fluorescence experiments are performed. Single pass operation yielding beam energies up to 40 MeV has been used for tests of the Free Electron Laser (FEL) beamline and for the investigation of spontaneous emission from the undulator. Two and three pass operation at higher energies produces beam for electron scattering experiments,(e,e') and (e,e'x), as well as for the production of channeling radiation. True cw operation allows for energies up to 84 MeV limited by the capacity of the He refrigerator. At higher energies the duty factor has to be reduced and pulse length is on the order of seconds. The successful operation of the entire accelerator was the result of several developments: six accelerating cavities fabricated from RRR = 280 niobium raised the average field gradient to 6 MV/m; the control systems for gun, rf, cavity tuners, and the beam transport system including beam diagnostics have been integrated into a reliable remote control of the S-DALINAC; and computer controlled path length adjustments for the two recirculating beamlines were installed for optimization of the reinjection phase.

    Full Text Available The manner of designing biogas plants is eagerly described by each and every seller or supplier of the respective technology. Numerous feasibility studies comprising forecasts of future operation featuring different quality levels have been written. However, it is rarely possible to obtain information comparing the anticipated future numbers and real values. Nevertheless, an evaluation of past operation of BGP is of utmost importance for calibration of the calculation methods used for designing of future BGPs. Information obtained on the basis of an evaluation is also useful for the purpose of verification of correct functionality of the equipment as well as optimisation of its operation with the objective of achieving the planned (or even better values of profitability of each respective project. A comprehensive analysis of a biogas plant is a project sensitive to accuracy of inputs. Measurements of amounts and quality of the feed substrate throughout the whole year, which comprises numerous criteria, is highly demanding and complicated, and therefore the objective of this evaluation is to analyze the performance, production and consumption of the biogas plant in the course of a calendar year (Schulz et al., 2004. Power measuring tasks are performed using calibrated gauges (which are mostly used for invoicing purposes, thus ensuring accuracy and credibility of the input data.

    In the frame of minimizing the operation lost of the RSG-GAS reactor, operation using one line cooling system at certain power range is being evaluated. Analysis the performance of cooling system for determining maximum power should be carried out. Analysis was carried out based on heat exchanger calculation using actual operation data. Constraints imposed to the analysis are that inlet cooling system to the reactor core shall be less than 42 o C. The result shows that by using one line of primary and secondary coolant flow of 1780 m exp. 3/hr and 2000 m 3 /hr and secondary coolant temperature from the cooling tower of 38 o C, the primary coolant to the core will be reach 42 o C if reactor operated at power of 16 MW

    The environmental charging of satellite surfaces during geomagnetic substorms is the apparent cause of a significant number of anomalous events occurring on geosynchronous satellites since the early 1970's. Electromagnetic pulses produced in connection with the differential charging of insulators can couple into the spacecraft harness and cause electronic switching anomalies. An investigation conducted to determine the response of the spacecraft surfaces to substorm particle fluxes makes use of a harness transient detector. The harness transient detector, called the Transient Event Counter (TEC) was built and integrated into the Canadian-American Communications Technology Satellite (CTS). A description of the TEC and its operational characteristics is given and the obtained data are discussed. The data show that the satellite surfaces appear to be charged to the point that discharges occur and that the discharge-induced transients couple into the wire harnesses.

    Today's complexity of systems where man is involved has led to the development of more and more sophisticated information processing systems where decision making has become more and more difficult. The operator task has moved from operation to supervision and the production tool has become indissociable from its numerical instrumentation and control system. The integration of more and more numerous and sophisticated control indicators in the control room does not necessary fulfill the expectations of the operation team. It is preferable to develop cooperative information systems which are real situation understanding aids. The stake is not the automation of operators' cognitive tasks but the supply of a reasoning help. One of the challenges of interactive information systems is the selection, organisation and dynamical display of information. The efficiency of the whole man-machine system depends on the communication interface efficiency. This article presents the principles and specificities of man-machine supervision systems: 1 - principle: operator's role in control room, operator and automation, monitoring and diagnosis, characteristics of useful models for supervision; 2 - qualitative reasoning: origin, trends, evolutions; 3 - causal reasoning: causality, causal graph representation, causal and diagnostic graph; 4 - multi-points of view reasoning: multi flow modeling method, Sagace method; 5 - approximate reasoning: the symbolic numerical interface, the multi-criteria decision; 6 - example of application: supervision in a spent-fuel reprocessing facility.

    We demonstrate the use of two different wavelength ranges of excitation light as inputs to remotely trigger the responses of the self-assembled DNA devices (D-OR). As an important feature of this device, the dependence of the readout fluorescent signals on the two external inputs, UV excitation for 1 min and/or near infrared irradiation (NIR) at 800 nm fs laser pulses, can mimic function of signal communication in OR logic gates. Their operations could be reset easily to its initial state. Furthermore, these DNA devices exhibit efficient cellular uptake, low cytotoxicity, and high bio-stability in different cell lines. They are considered as the first example of a photo-responsive DNA logic gate system, as well as a biocompatible, multi-wavelength excited system in response to UV and NIR. This is an important step to explore the concept of photo-responsive DNA-based systems as versatile tools in DNA computing, display devices, optical communication, and biology. © 2016 WILEY-VCH Verlag GmbH & Co.

    2016-08-01

    In milling, an accurate prediction of chatter is still one of the most complex problems in the field. The presence of these self-excited vibrations can spoil the surface of the part and can also cause a large reduction in tool life. The stability diagrams provide a practical selection of the optimum cutting conditions determined either by time domain or frequency domain based methods. Applying these methods parametric or parameter traced representations of the linear stability limits can be achieved by solving the corresponding eigenvalue problems. In this work, new analytical formulae are proposed related to the parameter domains of both Hopf and period doubling type stability boundaries emerging in the regenerative mechanical model of time periodical milling processes. These formulae are useful to enrich and speed up the currently used numerical methods. Also, the destabilization mechanism of double period chatter is explained, creating an analogy with the chatter related to the Hopf bifurcation, considering one dominant mode and using concepts established by the Pioneers of chatter research.

    In the frame of minimizing the operation-cost, operation mode using one line cooling system is being evaluated. Maximum reactor power shall be determined to assure that the existing safety criteria are not violated. The analysis was done by means of a core thermal hydraulic code, COOLOD-N. The code solves core thermal hydraulic equation at steady state conditions. By varying the reactor power as the input, thermal hydraulic parameters such as fuel cladding and fuel meat temperatures as well as safety margin against flow instability were calculated. Imposing the safety criteria to the results, maximum permissible power for this operation was obtained as much as 17.1 MW. Nevertheless, for operation the maximum power is limited to 15MW

    In the previous paper, the authors pointed out correspondence between a supersymmetric double-well matrix model and two-dimensional type IIA superstring theory on a Ramond–Ramond background from the viewpoint of symmetry and spectrum. This was confirmed by agreement between planar correlation functions in the matrix model and tree-level amplitudes in the superstring theory. In order to investigate the correspondence further, in this paper we compute correlation functions to all order of genus expansion in the double scaling limit of the matrix model. One-point functions of operators protected by supersymmetry terminate at some finite order, whereas those of unprotected operators yield non-Borel summable series. The behavior of the latter is characteristic in string perturbation series, providing further evidence that the matrix model describes a string theory. Moreover, instanton corrections to the planar one-point functions are also computed, and universal logarithmic scaling behavior is found for non-supersymmetric operators.

    A complete plasma control system (PCS) has been developed for KSTAR's first plasma campaign as a collaborative project with the DIII-D team. The KSTAR real time plasma control system is based on a conceptual design by Jhang and Choi [Hogun Jhang, I.S. Choi, Fusion Engineering and Design 73 (2005) 35-49] and consists of a fast real-time computer/communication cluster and software derived from the GA-PCS [Penaflor, B.G., et.al., Fusion Engineering and Design, 83 (2) (2008) 176]. The system has been used for simulation testing, poloidal field (PF) coil power supply commissioning and first plasma control. The seven sets of up-down symmetric, superconducting PF coil/power supply systems have been successfully tested. Reflective memory (RFM) is utilized as the primary actuator/PCS real-time communication layer and PCS synchronization with KSTAR timing system and slower control devices is achieved through an EPICS implementation. Consistent feedback loop times of 100 microseconds has been achieved during PF coil power supply testing and first plasma commissioning. Here we present the 'Day-One' plasma control system in its final form for the first plasma experimental campaign of KSTAR and describe how the system has been utilized during magnet commissioning and plasma startup experiments.

    1984-01-01

    Man's ability to live and perform useful work in space was demonstrated throughout the history of manned space flight. Current planning envisions a multi-functional space station. Man's unique abilities to respond to the unforeseen and to operate at a level of complexity exceeding any reasonable amount of previous planning distinguish him from present day machines. His limitations, however, include his inherent inability to survive without protection, his limited strength, and his propensity to make mistakes when performing repetitive and monotonous tasks. By contrast, an automated system does routine and delicate tasks, exerts force smoothly and precisely, stores, and recalls large amounts of data, and performs deductive reasoning while maintaining a relative insensitivity to the environment. The establishment of a permanent presence of man in space demands that man and machines be appropriately combined in spaceborne systems. To achieve this optimal combination, research is needed in such diverse fields as artificial intelligence, robotics, behavioral psychology, economics, and human factors engineering.

High magnetic field operation is a favorable approach to enlarge relative plasma performance without increasing normalized beta or plasma current. Exploration of one-dimensional current density profile and its optimization process for the K-DEMO steady-state operation are reported in this paper. Numerical analysis is conducted with an integrated plasma simulation code package incorporating a transport code with equilibrium and current drive modules. Operation regimes are addressed with zero-dimensional system analysis. One-dimensional plasma current density profile is calculated based on equilibrium, bootstrap current analysis, and thermal transport analysis. The impact of self and external heating profiles on those parameters is considered self-consistently, where thermal power balance and 100% non-inductive current drive are the main constraints during the whole exploration procedure. Current and pressure profiles are identified as a reference steady-state profile by minimizing the external heating power with desired fusion power.

    1980-01-01

    This book is an attempt to describe briefly the nature of radioactivity, how it arises in the day-to-day operation of a nuclear reactor, how and why a small fraction is introduced into the environment in a controlled manner, and on what basis such judgements are made. It is an account of current practice, and an attempt to be didactic rather than polemic. As a general subject area it is one which involves many disciplines and therein lies its particular scientific interest, especially for the ecologist. It is also a subject area of continuing research and one of increasing public awareness. The chapters are entitled: radioisotopes - their characterization and interaction with matter; the radiation background; radiation and man; nuclear reactors and their fuel cycles; radioactive wastes and the public; environmental behaviour and effects; the future.

    In this paper, based on a one-neuron recurrent neural network, a novel k-winners-take-all ( k -WTA) network is proposed. Finite time convergence of the proposed neural network is proved using the Lyapunov method. The k-WTA operation is first converted equivalently into a linear programming problem. Then, a one-neuron recurrent neural network is proposed to get the kth or (k+1)th largest inputs of the k-WTA problem. Furthermore, a k-WTA network is designed based on the proposed neural network to perform the k-WTA operation. Compared with the existing k-WTA networks, the proposed network has simple structure and finite time convergence. In addition, simulation results on numerical examples show the effectiveness and performance of the proposed k-WTA network.

    This paper deals with the methodology to implement the man-machine system (MMS) with enhanced human friendliness for nuclear power plants. The relevant technologies are investigated from the two view points: One is integrated multi-media usage for user-computer interface and the other cognitive engineering for user-task interaction. Promising MMS design methodologies, concepts, and their limitations are discussed. To overcome uncertain factors found in human behaviors or individual differences in performance and preference of operators, a design appproach to natural and flexible man-computer interactive environment is proposed by intergrated use of not only cognitive and psychological knowledge but also advanced media technology. Multi-media operator support system under development is shown as an example to evaluate the effectiveness of the new approach and future advancement is prospected. (orig.)

    An expression for the U(3) content of the matrix elements of one- and two-body operators in Elliott's basis is obtained. Three alternative ways of evaluating this content with increasing performance in computing time are presented. All of them allow an exact representation of that content in terms of integers, avoiding rounding errors in the computer codes. The role of dual bases in dealing with non-orthogonal bases is also clarified. (author)

    Torrefaction reactor model is required for the development of reactor and process design for biomass torrefaction. In this study, a one-dimensional reactor model is developed based on the kinetic model describing volatiles components and solid evolution and the existing thermochemical model considering the heat and mass balance. The developed reactor model used the temperature and flow rate of the recycled gas as the practical manipulated variables instead of the torrefaction temperature. The temperature profiles of the gas and solid phase were generated, depending on the practical thermal conditions, using developed model. Moreover, the effect of each selected operating variables on the parameters of the torrefaction process and the effect of whole operating variables with particular energy yield were analyzed. Through the results of sensitivity analysis, it is shown that the residence time insignificantly influenced the energy yield when the flow rate of recycled gas is low. Moreover, higher temperature of recycled gas with low flow rate and residence time produces the attractive properties, including HHV and grindability, of torrefied biomass when the energy yield is specified. - Highlights: • A one-dimensional reactor model for biomass torrefaction is developed considering the heat and mass balance. • The developed reactor model uses the temperature and flow rate of the recycled gas as the practical manipulated variables. • The effect of operating variables on the parameters of the torrefaction process is analyzed. • The results of sensitivity analysis represent notable discussions which were not done by the previous researches

  8. One-point functions of non-SUSY operators at arbitrary genus in a matrix model for type IIA superstrings

    2017-06-01

    Full Text Available In the previous paper, the authors pointed out correspondence between a supersymmetric double-well matrix model and two-dimensional type IIA superstring theory on a Ramond–Ramond background from the viewpoint of symmetry and spectrum. This was confirmed by agreement between planar correlation functions in the matrix model and tree-level amplitudes in the superstring theory. In order to investigate the correspondence further, in this paper we compute correlation functions to all order of genus expansion in the double scaling limit of the matrix model. One-point functions of operators protected by supersymmetry terminate at some finite order, whereas those of unprotected operators yield non-Borel summable series. The behavior of the latter is characteristic in string perturbation series, providing further evidence that the matrix model describes a string theory. Moreover, instanton corrections to the planar one-point functions are also computed, and universal logarithmic scaling behavior is found for non-supersymmetric operators.

    We describe a numerical method applied to the first-order form of one-speed slab-geometry discrete ordinates equations modelling time-independent neutron transport problems with anisotropic scattering, with no interior source and defined in a nonmultiplying homogeneous host medium. Our numerical method is concerned with the generation of the spectrum and of a vector basis for the null space of the one-speed slab-geometry discrete ordinates operator. Moreover, it allows us to overcome the difficulties introduced in previous methods by anisotropic scattering and by angular quadrature sets of high order. To illustrate the positive features of our numerical method, we present numerical results for one-speed slab-geometry neutron transport model problems with anisotropic scattering

    The quality of produced and discharged waters is of increasing concern as the overall quality of potable waters within many regions of the country becomes a critical issue. The impact of discharged waters on the downstream water quality, as well as the flora and fauna within a discharge zone, is dependent on the quality of the water ultimately released into the system. In many regions of the country, discharge permits are being re-evaluated and sometimes recalled due to the actual and perceived impact upon surface and subsurface waters, particularly those providing water utilized by the human population. The engineering, design and testing of a system to treat produced waters from oil operations in Wyoming is addressed in this study. This work was designed and performed by students and faculty in the Environmental Science and Engineering and Petroleum Engineering departments at the Colorado School of Mines. The system consists of overland flow units and a constructed wetlands unit. The system units can be independently evaluated. The water is drawn from active settling ponds above the test site. Produced waters are actively being discharged into the drainage basin. Waters flowing through the test units are likewise discharged after treatment. The system has been operational since June, 1991 and monthly sampling and testing will continue through March, 1992. Initial results having been very promising. Aeration, precipitation and bacterial activity in the overland flow and wetland units appears to nearly eliminate the sulfide problem present and significantly reduce the released radium concentration. These are the constituents of major concern although testing for other chemicals of concern, including hydrocarbon content is also analyzed

    2010-05-01

    A natural seismicity of Kuznetsk Basin is confined in the main to mountain frame of Kuznetsk hollow. In this paper materials of experimental work with local station networks within sediment basin are presented. Two types of seismicity display within Kuznetsk hollow have been understood: first, man-caused seismic processes, confined to mine working and concentrated on depths up to one and a half of km; secondly, seismic activations on depths of 2-56 km, not coordinated in plan with coal mines. Every of studied seismic activations consists of large quantity of earthquakes of small powers (Ms=1-3). From one to first tens of earthquakes were recorded in a day. The earthquakes near mine working shift in space along with mine working, and seismic process become stronger at the instant a coal-plough machine is operated, and slacken at the instant the preventive works are executed. The seismic processes near three lavas in Kuznetsk Basin have been studied in detail. Uplift is the most typical focal mechanism. Activated zone near mine working reach in diameter 1-1,5 km. Seismic activations not linked with mine working testify that the subsoil of Kuznetsk hollow remain in stress state in whole. The most probable causes of man-caused action on hollow are processes, coupled with change of physical state of rocks at loss of methane from large volume or change by mine working of rock watering in large volume. In this case condensed rocks, lost gas and water, can press out upwards, realizing the reverse fault mechanism of earthquakes. A combination of stress state of hollow with man-caused action at deep mining may account for incipient activations in Kuznetsk Basin. Today earthquakes happen mainly under mine workings, though damages of workings themselves do not happen, but intensive shaking on surface calls for intent study of so dangerous phenomena. In 2009 replicates of the experiment on research of seismic activations in area of before investigated lavas have been conducted

    To enable complete rejection of holder-related events in the upcoming CRESST-III dark matter search experiment, the scintillating target crystals are held by calcium tungstate sticks (iSticks) instrumented with tungsten transition edge sensors (TESs). Since the iStick signals are used exclusively for vetoing, it is sufficient to register if an event happened in any stick, without knowing which one. This allows the operation of all iSticks in a single readout circuit, requiring just one SQUID magnetometer. The talk describes the effect of bias current heating and corresponding hysteresis phenomena known in single-TES circuits, and the resulting conditions for stability in multiple-TES circuits. The fundamentally different behaviour of parallel and series circuits and resulting design choices are explored.

  18. Bidirectional control of a one-dimensional robotic actuator by operant conditioning of a single unit in rat motor cortex

    Directory of Open Access Journals (Sweden)

    Pierre-Jean eArduin

    2014-07-01

    Full Text Available The design of efficient neuroprosthetic devices has become a major challenge for the long-term goal of restoring autonomy to motor-impaired patients. One approach for brain control of actuators consists in decoding the activity pattern obtained by simultaneously recording large neuronal ensembles in order to predict in real-time the subject’s intention, and move the prosthesis accordingly. An alternative way is to assign the output of one or a few neurons by operant conditioning to control the prosthesis with rules defined by the experimenter, and rely on the functional adaptation of these neurons during learning to reach the desired behavioral outcome. Here, several motor cortex neurons were recorded simultaneously in head-fixed awake rats and were conditioned, one at a time, to modulate their firing rate up and down in order to control the speed and direction of a one-dimensional actuator carrying a water bottle. The goal was to maintain the bottle in front of the rat’s mouth, allowing it to drink. After learning, all conditioned neurons modulated their firing rate, effectively controlling the bottle position so that the drinking time was increased relative to chance. The mean firing rate averaged over all bottle trajectories depended non-linearly on position, so that the mouth position operated as an attractor. Some modifications of mean firing rate were observed in the surrounding neurons, but to a lesser extent. Notably, the conditioned neuron reacted faster and led to a better control than surrounding neurons, as calculated by using the activity of those neurons to generate simulated bottle trajectories. Our study demonstrates the feasibility, even in the rodent, of using a motor cortex neuron to control a prosthesis in real-time bidirectionally. The learning process includes modifications of the activity of neighboring cortical neurons, while the conditioned neuron selectively leads the activity patterns associated with the prosthesis

    The traditional operator job is changing, which among other things has generated a need for better job training. Surprisingly increased process automation has lead to increased operator qualifications, i.e. basic job training but also up-date and rehearsal training within certain fixed intervals. There are several, similar models for instructional system development available in the literature. One model which is of special interest integrates Operator Training development and Man-Machine Interfaces development. The extent to which Systematic Operator Training has been implemented varies with branches and companies. The nuclear power branch is given as an example in the report. This branch probably represents something better than the average among the process industries.(author)

    1972-01-01

    Erasable-memory programs (EMPs) designed for the guidance computers used in the command (CMC) and lunar modules (LGC) are described. CMC programs are designated COLOSSUS 3, and the associated EMPs are identified by a three-digit number beginning with 5. LGC programs are designated LUMINARY 1E, and the associated EMPs are identified, with one exception, by a three-digit number beginning with 1. The exception is EMP 99. The EMPs vary in complexity from a simple flagbit setting to a long and intricate logical structure. They all, however, cause the computer to behave in a way not intended in the original design of the programs; they accomplish this off-nominal behavior by some alteration of erasable memory to interface with existing fixed-memory programs to effect a desired result.

    To make real and accurate dose assessment method so far, it is necessitated to provide ''Reference Japanese Man'' based on anotomical, physiological and biochemical data of Japanese people instead of the Reference Man presented in ICRP Publications 23 and 30. This review describes present status of researched for the purpose of establishing of Reference Japanese Man. The Reference Japanese Man is defined as a male or female adult who lives in Japan with a Japanese life-style and food custom. His stature and body weight, and the other data was decided as mean values of male or female people of Japan. As for food custom, Japanese people take significantly smaller amount of meat and milk products than Western people, while larger intake amount of cereals and marine products such as fish or seaweeds. Weight of organs is a principal factor for internal dose assessment and mean values for living Japanese adult has been investigated and the value employable for dose assessment for organs and tissues are shown. To employ these values of Reference Japanese Man, it should be taken into account of age. Metabolic parameters should also be considered. Iodine metabolism in Japanese is quite different from that of Western people. The above-mentioned data are now tentatively employing in modification of table of MIRD method and others. (Takagi, S.)

    Hysterectomy dates back to 120BC and is the second most commonly performed gynecological surgery in the world. Cosmetic demands and the necessity of rapid return to work have contributed to the minimally invasive laparoscopic approach for hysterectomy. The majority of reports describe the use of three or four incisions to perform the surgery (two or three for manipulation and one for optics). This work describes our experience with using only two ports for 11 patients who underwent video-laparoscopic hysterectomy surgery. One port was used for the optical system, and the second was used for manipulation. Early and late surgery complications, as well as the time to return to work and daily activities, were assessed. The mean age of the patients was 41.4 years old (range 16 to 52 years) and the mean uterine weight was 133.54 g, ranging from 35 g and 291 g. The operative time ranged from 30 to 60 minutes (average 46.4 minutes) and the hospital stay ranged between 24 and 48 hrs. No intraoperative complications occurred, and no early or late postoperative complications were recorded. Patients reported minimal pain during the first 24-48 hrs in the hospital. Patients returned to their daily activities within seven days after surgery. Clinical care follow-up continued until the 40th postoperative day. The laparoscopic hysterectomy technique with a single port for manipulation is a feasible procedure when the uterine weight is not greater than 400 mg with little postoperative pain. The patients had an early return-to-work and daily activities and a better cosmetic outcome. These preliminary data led us to make the one-operative port laparoscopic hysterectomy the procedure of choice for patients with a low uterine weight.

    Integrated testing (such as Multi-Element Integrated Test (MEIT)) is critical to reducing risks and minimizing problems encountered during assembly, activation, and on-orbit operation of large, complex manned spacecraft. Provides the best implementation of "Test Like You Fly:. Planning for integrated testing needs to begin at the earliest stages of Program definition. Program leadership needs to fully understand and buy in to what integrated testing is and why it needs to be performed. As Program evolves and design and schedules mature, continually look for suitable opportunities to perform testing where enough components are together in one place at one time. The benefits to be gained are well worth the costs.

    2000-12-01

    The aptitude for symbolization, characteristic of man, is revealed not only in artistic representations and funerary practices. It is exhibited by every manifestation of human activity or representation of natural phenomena that assumes or refers to a meaning. We can recognize functional symbolism (tool-making, habitative or food technology), social symbolism, (language and social communication) and spiritual symbolism (funerary practices and artistic expressions). On the basis of these concepts, research into symbolism in prehistoric man allows us to recognize forms of symbolism already in the manifestations of the most ancient humans, starting with Homo habilis (or rudolfensis). Toolmaking, social organization and organization of the territory are oriented toward survival and the life of the family group. They attest to symbolic behaviors and constitute symbolic systems by means of which man expresses himself, lives and transmits his symbolic world. The diverse forms of symbolism are discussed with reference to the different phases of prehistoric humanity.

    , 2007 and was successfully concluded as planned on October 31, 2008. During this time period the Dawn IPS was operated mostly at full power for approximately 6500 hours, consumed 71.7 kg of xenon and delivered approximately 1.8 km/s of delta V to the spacecraft. The thrusting to Mars was followed by a coasting period of approximately 3.5 months that included a Mars flyby in February of 2009. The Mars flyby provided a gravity assist (MGA) for a plane change and approximately 1 km/s of heliocentric energy increase and is the only part of the mission following launch in which a needed velocity change is not accomplished by the IPS. During the coast period IPS was operated for a trajectory correction maneuver and for engineering tests but was not operated for primary propulsion. Closest approach to Mars occurred as planned on February 17, 2009 and was followed by another coasting period of just under 4 months in duration. During this last coasting phase IPS was operated only for routine maintenance activities and for system engineering tests. Deterministic thrusting for heliocentric transfer to Vesta resumed on June 8, 2009. Since resumption of cruise to Vesta IPS has been operated at throttled power levels, most of the time at full power, and with a duty cycle of approximately 93%, leading to an arrival at Vesta in July of 2011 and arrival at Ceres in February 2015. This paper provides an overview of Dawn's mission objectives and the results of Dawn IPS mission operations through one year from the spacecraft's rendezvous with Vesta.

    2007-01-01

    The paper presents the results of the independent analysis of the operational event which took place on 07.11.2003 at Unit 1 of Rostov NPP. The event started with switching off the electrical generator of the turbine due to a short cut at the local switching substation. The turbine isolating valves closed to prevent damage of the turbine. The condenser dump valves (BRU-K) and the atmospheric dump valves (BRU-A) opened to release the vapour generated in the steam generators. After the pressure decrease in the steam generators BRU-K and BRU-A closed but one valve stuck opened. The emergency core cooling system was activated automatically. The main circulation pump of the loop corresponding to the steam generator with the stuck BRU-A was tripped. The stuck valve was closed by the operational stuff manually. No safety limits were violated. The analysis of the event was carried out using ATHLET code. A reasonable agreement was achieved between the calculated and measured values. (author)

    1997-12-31

    The Idaho National Engineering and Environmental Laboratory`s Heat Cycle Research project is developing a technology base that will increase the use of moderate-temperature hydrothermal resources to generate electrical power. One of the concepts under investigation is the use of a metastable, supersaturated turbine expansion. This expansion process supports a supersaturated vapor. If brought to equilibrium conditions, liquid condensate would be present in the expanding vapor. Analytical studies show that a plant designed to operate with this expansion will have an improvement in the brine effectiveness of up to 8% provided there is no adverse impact on turbine performance. Determining the impact of this expansion on turbine performance is focus of the project investigations being reported.

    Abundant, cheap computing power has provided industry with a far greater opportunity than was available one or two decades ago to automate industrial processes and to improve the man-machine interface. Exciting innovations in knowledge representation methods arising from artificial intelligence research pave the way for advanced support systems for assisting plant operators. AECL has recognized the importance of knowledge based system technology, particularly expert systems, in the achievement of this objective and also, as a strategic technology to be fully exploited in the next generation of CANDU reactors. Operator Companion, an expert system intended to diagnose plant faults and advise the operator on appropriate restoring or corrective actions, is a major undertaking which is receiving support within the research and engineering groups of AECL

    2017-01-01

    The Appendix to Kant’s Toward perpetual peace is commonly viewed as an explication of the systematic relations between political practice and normative political theory. This paper provides an alternative interpretation to Kant’s main aim in the Apendix which is to provide an argument against...... that Kant’s argument against the practical man is based on a proto-phenomenological analysis of moral experience. The practical man’s attempt to describe political practice in purely non-normative terms is, Kant believes, necessarily self-undermining because it denies one of the most basic aspects of human...

  19. Man machine interface and its implementation

    International Nuclear Information System (INIS)

    1992-01-01

    Sizewell B is the latest nuclear power station to be constructed in the United Kingdom: its Man-Machine Interfaces are therefore, by definition, the state-of-the-art. This paper discusses the principal Man-Machine Interfaces used in the operation of the station, and the systems that implement them. The Man-Machine Interface facilities discussed are: in the Main Control Room, which is used for normal operation and shutdown of the plant: in the Auxiliary Shutdown Room, which allows shutdown of the reactor if evacuation of the main Control Room is necessary: and in the Technical Support Centre, which is used for remote monitoring of the plant. The Man-Machine Interfaces that are described are parts of a station-wide group of interlinked computer systems called the Data Processing and Control System. This system collects data from the plant and displays it to the operators via discrete devices and on graphical computer displays. It also acquires control inputs from the operators via switches, which are then used to provide remote manual control, modulating control and sequence control. The computer system that handles the plant process data and alarm information displays uses a windowing interface with keyboard and trackerball navigation to allow easy retrieval and viewing of information. It is this system that is the main topic of this paper. (author)

    2013-01-01

    We study the numerical recovery of Manning\\'s roughness coefficient for the diffusive wave approximation of the shallow water equation. We describe a conjugate gradient method for the numerical inversion. Numerical results for one-dimensional models are presented to illustrate the feasibility of the approach. Also we provide a proof of the differentiability of the weak form with respect to the coefficient as well as the continuity and boundedness of the linearized operator under reasonable assumptions using the maximal parabolic regularity theory. © 2012 Elsevier B.V.

    The discussion of cultural and sociological consequences of computer evolution is hindered by human prejudice. For example the sentence 'a computer is at best as intelligent as its programmer' veils actual developments. Theoretical limits of computer intelligence are the limits of intelligence in general. Modern computer systems replace not only human labour, but also human decision making and thereby human responsibility. The historical situation is unique. Human head-work is being automated and man is loosing function. (orig.) [de

    Purpose: The objective of this study is to evaluate the stability of ProteusOne, the 1st commercial PBS proton system, throughout the daily QA and monthly over 6 month clinical operation. Method: Daily QA test includes IGRT position/repositioning, output in the middle of SOBP, beam flatness, symmetry, inplane and crossplane dimensions as well as energy range check. Daily range shifter QA consist of output, symmetry and field size checks to make sure its integrity. In 30 mins Daily QA test, all the measurements are performed using the MatriXXPT (IBA dosimetry). The data from these measurement was collected and compare over the first 6 month of clinical operation. In addition to the items check in daily QA, the summary also includes the monthly QA gantry star shots, absolute position check using a novel device, XRV-100. Results: Average machine output at the center of the spread out bragg peak was 197.5±.8 cGy and was within 1%of the baseline at 198.4 cGy. Beam flatness was within 1% cross plane with an average of 0.67±0.12% and 2% in-plane with an average of 1.08±0.17% compared to baseline measurements of 0.6 and 1.03, respectively. In all cases the radiation isocenter shift was less than or equal to 1mm. Output for the range shifter was within 2% for each individual measurement and averaged 34.4±.2cGy compare to a baseline reading of 34.5cGy. The average range shifter in and cross plane field size measurements were 19.8±0.5cm and 20.5±0.4cm compared with baseline values of 20.19cm and 20.79cm, respectively. Range shifter field symmetry had an average of less 1% for both in-plane and cross plane measurements. Conclusion: All machine metrics over the past 6 months have proved to be stable. Although, some averages are outside the baseline measurement they are within 1% tolerance and the deviation across all measurements is minimal.

    One of potential hazard in Nuclear Power Plant is the failure of its operation. The accident or operation failure in the reactor must be concerned event its probability is low. The important thing should be concerned is 'Analysis of Man-Machine Interaction (MMI) for Control and Display System in Main Control Room (MCR) of Nuclear Power Reactor', especially LWR type. Control and Display System in MCR of Reactor is the main part of MMI link process in Reactor MCR work system. Signal from display system showed performance process in reactor, while this signal will be received by operator. This signal will be described through central nerve for making decision what kind must be done. Then the operator manage the next process of reactor operation through control system. So by knowing Analysis of Man-Machine Interaction for Control and Display System in Main Control Room of Power Reactor, we can understand human error probability of the operator in reactor operation

    Typhoon Man-Yi was pummeling the Japanese island of Okinawa with winds between 230 and 295 kilometers per hour (125-160 knots, 144-184 miles per hour) and heavy rain on the morning of July 13, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured this image. The immense storm covered hundreds of kilometers with spiraling bands of thunderstorms, though it had lost the distinctive cloud-free eye it exhibited the day before. Typhoons are common in Japan, but powerful typhoons usually strike the island nation later in the year. The Japan Meteorological Agency said that Man-Yi is the fourth typhoon of the 2007 season and may be the most powerful ever observed in the northwest Pacific in July, reported Kyodo News. The Joint Typhoon Warning Center expected the typhoon to strike Kyushu, a southern Japanese island, on July 14, and then curve northeast along the eastern shore of Japan. By the time the storm reaches Tokyo on July 15, it should be degraded to a tropical storm. As of July 13, Typhoon Man-Yi had injured eight and flooded twenty houses in Okinawa, and forced airlines to cancel hundreds of flights, said Kyodo News. The storm was expected to bring heavy rain to Japan's Pacific coast. NASA image created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response team.

    Marie Curie was awarded the Nobel Prize in chemistry 1911. During the preceding year a rumour had circulated in Stockholm that she had had an affaire with one of her assistants. She received a letter, in which she was told that there had been strong opposition to her election not on scientific but moral grounds, and that she should not go to Stockholm, because nobody could forsee what reactions her appearance at the prize ceremony could evoke. Emil Kleen, a man of violent temper and radical opinions, reacted strongly to these rumours. He wrote a paper, with a violent attack on Gustaf Retzius, previous professor of Histology at Karolinska Institutet. Rightly or wrongly he suspected him to be the author of the infamous letter. Retzius is described as a dilletant in scientific matters, as a "sexual hyena" and a garroulus old man. This portrait of Retzius is of course most unfair, but the portrait of Emil Kleen by the famous swedish artist Bruno Liljefors is a masterpiece and one of the most valuable of the Swedish Medical Association.

    The Cobra-P drug-eluting stent (DES) system consists of cobalt chromium alloy with bio-absorbable siloxane sol-gel matrix coating that elutes low dose paclitaxel within 6 months. The aim of this first-in-man trial was to evaluate the safety and performance of 2 doses of the Cobra-P DES. A total of 60 lesions (54 patients) were sequentially assigned to 2 different paclitaxel doses: group A (3.7 μg/18mm, n=30) or group B (8 μg/18mm, n=30). The primary endpoint was MACE at 4 months defined as cardiac death, myocardial infarction, and target lesion revascularization. Patient and lesion characteristics were matched between the 2 groups except for male sex. MACE at 4 months was 3.3% and 0% respectively (P=1.000) and at 1-year follow-up remained unchanged. In-stent late loss at 4 months was similar in both groups (0.36 ± 0.30mm and 0.34 ± 0.20mm P=.773). In this FIM study, implantation of the Cobra-P low dose paclitaxel-eluting stent with a bioabsorbable sol-gel coating was proven to be feasible and safe. Moderate neointimal proliferation was observed as well as an acceptable MACE rate up to 1 year. © 2014.

    Space Station Freedom operations management concepts must be responsive to the unique challenges presented by the permanently manned international laboratory. Space Station Freedom will be assembled over a three year period where the operational environment will change as significant capability plateaus are reached. First Element Launch, Man-Tended Capability, and Permanent Manned Capability, represent milestones in operational capability that is increasing toward mature operations capability. Operations management concepts are being developed to accomodate the varying operational capabilities during assembly, as well as the mature operational environment. This paper describes operations management concepts designed to accomodate the uniqueness of Space Station Freedoom, utilizing tools and processes that seek to control operations costs.

    The long term operative results of one-stage closure of isolated cleft palate with either the Veau-Wardill-Kilner V to Y pushback procedure or the Cronin modification were evaluated and compared retrospectively. A total of 116 consecutive patients with isolated cleft palate who had been operated on at the age of 18-24 months were followed up until 17-20 years of age. Twenty-four of the patients needed one or more additional operations on the palate, mainly pharyngeal flaps (20%) and repair of fistulas (10%). There was no significant difference in the number of patients who needed further operations, either between the two different operations or between the sexes, but the patients who presented with the most extensive clefts required the most operations.

    We show that the Wigner function W = Tr(△ρ) (an ensemble average of the density operator ρ, △ is theWigner operator) can be expressed as a matrix element of ρ in the entangled pure states. In doing so, converting fromquantum master equations to time-evolution equation of the Wigner functions seems direct and concise. The entangledstates are defined in the enlarged Fock space with a fictitious freedom.

    The paper depicts a software assessment system, Dynamic Interaction Analysis Support (DIAS), based on computer simulation technology for man-machine interfaces (MMI) of a control room. It employs a computer to simulate the operation procedures of operations on man-machine interfaces in a control room, provides quantified assessment, and at the same time carries out analysis on operational error rate of operators by means of techniques for human error rate prediction. The problems of placing man-machine interfaces in a control room and of arranging instruments can be detected from simulation results. DIAS system can provide good technical supports to the design and improvement of man-machine interfaces of the main control room of a nuclear power plant

  7. Pathways to man

    The study of radionuclide pathways leading to man generally has the goal of allowing us to predict human exposure from measurements of the radionuclide concentration in some segment of the environment. This modelling process provides a valuable tool in both the regulatory and health protection fields. However, most of the models in the regulatory field and in the health physics profession were designed to maximize exposure estimates. It is preferable to have scientifically defensible estimates and to add suitable safety factors at the end. Thus we are still faced with the development and validation of suitable models for many of the radionuclides of interest. The most useful models will include means of assessing variability and uncertainty. In this case variability might be considered as the differences in behavior due to age, sex or other factors in animals or man and those differences among plant species or animal species that determine their uptake factors. The uncertainty, on the other hand, would be the estimate of possible error in the experimental measurements. Model parameters would always have some variability even for site-specific cases and broad averages for population groups would have to include a factor expressing the possible variabilty and uncertainity. Thus any exposure calculation would have to be expressed with some range and valid assessments of this range are required

    A new and exciting discipline of human ecology is in the making. It has not, perhaps fortunately, found its bearings yet and remains to date overly dependent upon the limitations of sociology, biology, engineering and the sciences for its general theory, approaches, and philosophy. A new discipline with a world view and focussed on the human being and his habitat will hopefully emerge from a rich dialectic among scientists, humanists and policy makers educated and experienced in a variety of fields and committed to man's welfare. This new discipline and its practitioner must always be open to the revelations their knowledge will bring to man through the environmental processes. The implications of public policy, science and technology of industrial and post-industrial nations are all in need of considered re-examination by us all. Since their early application in these western societies we have witnessed the general downgrading of the world's environment. An ungrading in social priorities for the development of adequate housing, jobs, medical care and education which is almost always lower in rank than they should be is needed. The role of local groups, involving a well-informed and participating citizenship, in this process of changing priorities will always remain of prime importance, but no long-range goal in a rapidly-changing landscape is possible without broad national and local planning which contains ways and means of implementation.

  9. 1958 : Manning wants markets

    International Nuclear Information System (INIS)

    2008-01-01

    This article described the 2 opposing views in 1958 regarding how the big Montreal refinery market should be served. While the president of Imperial Oil expressed that Montreal refineries should not be forced to use domestic feedstocks, Alberta Premier Ernest Manning urged the Borden Commission to take immediate measures to expand the market for Canadian crude oil into Montreal. Manning argued that the dependence on Venezuelan crude in the Montreal refining market would pose a danger to the stability and development of the oil industry; loss of revenue for municipal, provincial and federal governments; and, an adverse effect on Canada's trade balance with the United States. The Premier suggested that these problems could be avoided by expanding the market for Canadian crude in Ontario and Quebec, in the U.S. Midwest, and in the Pacific Northwest. In 1958, the Canadian oil industry was divided on the Montreal market issue. Other key events in 1958 were listed. Waterton was characterized as Canada's biggest gas field, with reserves of 3 trillion cubic feet. A gas discovery at Berland River was considered the largest single-well exploration find in the world, flowing 27 million cubic feet per day on 1 drillstem. Two new refineries near Vancouver and Toronto were built to raise Canadian refining capacity to 813,000 barrels per day. 1 tab., 1 fig

  10. Quasi-periodic Schroedinger operators in one dimension, absolutely continuous spectra, Bloch waves, and integrable Hamiltonian systems

    Chierchia, L.

    1986-01-01

    In the first chapter, the eigenvalue problem for a periodic Schroedinger operator, Lf = (-d 2 /dx 2 + v)f = Ef, is viewed as a two-dimensional Hamiltonian system which is integrable in the sense of Arnold and Liouville. With the aid of the Floquet-BLoch theory, it is shown that such a system is conjugate to two harmonic oscillators with frequencies α and omega, being the rotation number for L and 2π/omega the period of the potential v. This picture is generalized in the second chapter, to quasi periodic Schroedinger operators, L/sub epsilon/, with highly irrational frequencies (omega 1 , ..., omega/sub d/), which are a small perturbation of periodic operators. In the last chapter, the absolutely continuous spectrum σ/sub ac/ of a general quasi-periodic Schroedinger operators is considered. The Radon-Nikodym derivatives (with respect to Lebesgue measure) of the spectral measures are computed in terms of special independent eigensolutions existing for almost ever E in σ/sub ac/. Finally, it is shown that weak Bloch waves always exist for almost ever E in σ/sub ac/ and the question of the existence of genuine Bloch waves is turned into a regularity problem for a certain nonlinear partial differential equation on a d-dimensional torus

    Rising costs and low energy prices were inhibiting the development of marginal fields on the Dutch Continental Shelf, resulting in a reduction in drilling activity and a loss of business opportunities. Independent benchmark surveys and critical analysis of total well costs showed the potential for major cost reductions that could turn many of the smaller offshore gas finds into economic development prospects. This triggered a change from traditional operating and contracting strategies to a partnering approach with the principal drilling and service contractors and the institution of a well-construction team (WCT). The WCT proved so successful, with an average well cost reduction of 21% in the first year, that a similar organization has been set up for all the land drilling and workover operations. This paper describes the strategies used and presents a comparison between the traditional performance and the results from the first year of operating as a WCT. The comparison includes the results of an independent benchmark study of 20 North Sea operating companies

    In the modern day operating room, the surgeon performs surgeries with the support of different medical systems that showcase patient information, physiological data, and medical images. It is generally accepted that numerous interactions must be performed by the surgical team to control the corresponding medical system to retrieve the desired information. Joysticks and physical keys are still present in the operating room due to the disadvantages of mouses, and surgeons often communicate instructions to the surgical team when requiring information from a specific medical system. In this paper, a novel user interface is developed that allows the surgeon to personally perform touchless interaction with the various medical systems, switch effortlessly among them, all of this without modifying the systems' software and hardware. To achieve this, a wearable RGB-D sensor is mounted on the surgeon's head for inside-out tracking of his/her finger with any of the medical systems' displays. Android devices with a special application are connected to the computers on which the medical systems are running, simulating a normal USB mouse and keyboard. When the surgeon performs interaction using pointing gestures, the desired cursor position in the targeted medical system display, and gestures, are transformed into general events and then sent to the corresponding Android device. Finally, the application running on the Android devices generates the corresponding mouse or keyboard events according to the targeted medical system. To simulate an operating room setting, our unique user interface was tested by seven medical participants who performed several interactions with the visualization of CT, MRI, and fluoroscopy images at varying distances from them. Results from the system usability scale and NASA-TLX workload index indicated a strong acceptance of our proposed user interface.

  16. Oedipus king: preparing man for the polis

    José Joaquim Pereira Melo

    2013-09-01

    Full Text Available Having Sophoclean play Oedipus King as a frame of reference, the purpose of this paper is to discuss the educative proposal conceived to the Greek Man as preparation for life in the polis. Although not intentionally, Sophocles pointed out an ideal of Man which, in his perspective, would fulfill Greek societal demands of that time. Such society was divided between myth and rationality and, as a result, Man found Himself in conflict and lacking direction for His life. Given that, Oedipus’ character represented the ideal behavior of that society, and it also made it possible for citizens to reflect and to discuss social, economic and political transformations taking place at that period. Thus Sophocles came up with a hero who was an educational model and a citizen’s as well. Furthermore, such hero differed from that one of the archaic Greek thought.

    This research topic was first established in China by Professor Shengzhao Long in 1981, with direct support from one of the greatest modern Chinese scientists, Xuesen Qian. In a letter to Shengzhao Long from October 22nd, 1993, Xuesen Qian wrote: “You have created a very important modern science subject and technology in China!” MMESE primarily focuses on the relationship between Man, Machine and Environment, studying the optimum combination of man-machine-environment systems. In this system, “Man” refers to working people as the subject in the workplace (e.g. operators, decision-makers); “Machine” is the general name for any object controlled by Man (including tools, machinery, computers, systems and technologies), and “Environment” describes the specific working conditions under which Man and Machine interact (e.g. temperature, noise, vibration, hazardous gases etc.). The three goals of optimization are to ensure "Safety, High efficiency and Economy" of man-machine-environment systems. These...

  19. Manned in Situ Confirmation of Lunar Ice

    Science.gov (United States)

    Gerené, S. P. B.; Hummeling, R. W. J.; Ockels, W. J.

    A study is performed to investigate the feasibility of a manned expedition to the Moon using the European Ariane-5 launcher. The primary objective of this lunar mission is to confirm the presence of water at the South-Pole craters. It is believed that these permanently shadowed craters contain water in the form of ice. Secondary objective is to perform lunar surface science and making a first step towards a lunar outpost. Early results show that a minimum of two Ariane-5 launches is required. In this `two Ariane' scenario the first launch will bring a Lunar Landing Vehicle (LLV) into low lunar orbit. The second will launch two astronauts in a Crew Transfer Vehicle into a rendez- vous trajectory with the LLV. Arrived at the Moon, the astronauts will enter the LLV, undock from the CTV and land at the designated site located near the rim of the South-Pole Shackleton crater. The transfer strategy for both spacecraft will be the so-called direct transfer, taking about four days. At arrival the LLV will start mapping the landing site at a ground resolution of one meter. As a consequence of the polar orbit, the CTV has to arrive fourteen days later and surface operations can take about twelve days, accumulating in a total mission-duration of 36 days. 32 days for the CTV and 22 days for the LLV. In case a `two Ariane' flight does not posses sufficient capabilities also a `three Ariane' scenario is developed, in which the LLV is split-up into two stages and launched separately. These two will dock at the Moon forming a descent stage and an ascent stage. The third launch will be a CTV. During surface operations, astronauts will set up a solar power unit, install the sample retrieval system and carry out surface science. Samples of the crater floor will be retrieved by means of a probe or robot guided along a cable suspended over the crater rim. Also, this paper shows the way in which European astronauts can be brought to the Moon for other future missions, like the

    1984-01-01

    In BWR nuclear power stations the Traversing Incore Probe (TIP) system is one of the most important components in reactor monitoring and control. In previous TIP systems, however, operators have suffered from the complexity of operation and long operation time required. The system presented in this paper realizes the automatic operation of the TIP system by monitoring and driving it with a process computer. This system significantly reduces the burden on customer operators and improves plant efficiency by simplifying the operating procedure, augmenting the accuracy of the measured data, and shortening operating time. The process computer is one of the PODIA (Plant Operation by Displayed Information Automation) systems. This computer transfers control signals to the TIP control panel, which in turn drives equipment by microprocessor control. The process computer contains such components as the CRT/KB unit, the printer plotter, the hard copier, and the message typers required for efficient man-machine communications. Its operation and interface properties are described

  3. The 'poor man's laryngogram'

    Bartelt, D.

    1991-01-01

    This paper is reassessment of an old method improved by well-directed application of well-known maneuvers of laryngo-pharyngeal function. Although not as visually attractive as a dedicated laryngogram (now hardly ever requested), it does render similarly reliable diagnostic information, which, supported, as occasionally necessary, by conventional tomography, can even surpass that given by the older technique. Its main advantage lies in providing cheap, quick, noninvasive studies with minimal descomfort for the patient. Should further investigation be necessary, for analysis of deep extension, modern cross-sectional imaging methods (especially MR) far surpass even dedicated laryngography in diagnostic value and can be based adequately on 'poor mans's laryngography'. Ways in which this method may be optimised, especially those involving laryngopharyngeal function, are briefly presented - with emphasis on relevant practical aspects - as are normal and abnormal findings.

  13. From the rights of man to the human rights: Man - nation - humanity

    Directory of Open Access Journals (Sweden)

    Zaharijević Adriana

    2008-01-01

    Full Text Available The insistence on the fact that human rights and the rights of man (codified in The Universal Declaration of Human Rights and Declaration of the Rights of Man and of the Citizen, respectively are not one and the same, which could be deduced from the notion of man common to both terms, is the key thesis of this text. By developing this motive, I try to determine the following: that the notion of man, by definition inclusive and abstractly non-discriminative term, is in fact established on tacit exclusions in the time of its inception (Enlightenment revolutinary era, and it was only upon these exclusions that the term man could have signified "the free and equal". Although the parallel or simultaneous evolution and implementation of the rights of man and national rights might seem contradictory, I seek to demonstrate that this paradox is only ostensible, arguing that the notion of man is itself limited and exclusionary, and is therefore compatible with the exclusivity which is the conditio sine qua non of nation. The consequences of nationalism - World Wars, primarily - proved that the conception of liberty and equality, based on the conception of fraternity of men (white European males, and of partial democracy pretending to be universal, cannot be maintained any further. Codification of universal human rights represents a reaction to this internal discrepancy inasmuch as it is a reaction to the destructiveness of all kinds of nationalisms. The notion of life, developed in this text, corresponds to the fundamental requirement for the right to life (as the first and the most basic of all human rights, which no longer belongs to "man", but to everyone.

  15. One-loop polarization operator of the quantum gauge superfield for 𝒩 = 1 SYM regularized by higher derivatives

    Science.gov (United States)

    Kazantsev, A. E.; Skoptsov, M. B.; Stepanyantz, K. V.

    2017-11-01

    We consider the general 𝒩 = 1 supersymmetric gauge theory with matter, regularized by higher covariant derivatives without breaking the BRST invariance, in the massless limit. In the ξ-gauge we obtain the (unrenormalized) expression for the two-point Green function of the quantum gauge superfield in the one-loop approximation as a sum of integrals over the loop momentum. The result is presented as a sum of three parts: the first one corresponds to the pure supersymmetric Yang-Mills theory in the Feynman gauge, the second one contains all gauge-dependent terms, and the third one is the contribution of diagrams with a matter loop. For the Feynman gauge and a special choice of the higher derivative regulator in the gauge fixing term, we analytically calculate these integrals in the limit k → 0. In particular, in addition to the leading logarithmically divergent terms, which are determined by integrals of double total derivatives, we also find the finite constants.

  16. AN/FSY-3 Space Fence System – Sensor Site One/Operations Center Integration Status and Sensor Site Two Planned Capability

    Science.gov (United States)

    Fonder, G. P.; Hack, P. J.; Hughes, M. R.

    This paper covers two topics related to Space Fence System development: Sensor Site One / Operations Center construction and integration status including risk reduction integration and test efforts at the Moorestown, NJ Integrated Test Bed (ITB); and the planned capability of Sensor Site Two. The AN/FSY-3 Space Fence System is a ground-based system of S-band radars integrated with an Operations Center designed to greatly enhance the Air Force Space Surveillance network. The radar architecture is based on Digital Beam-forming. This capability permits tremendous user-defined flexibility to customize volume surveillance and track sectors instantaneously without impacting routine surveillance functions. Space Fence provides unprecedented sensitivity, coverage and tracking accuracy, and contributes to key mission threads with the ability to detect, track and catalog small objects in LEO, MEO and GEO. The system is net-centric and will seamlessly integrate into the existing Space Surveillance Network, providing services to external users—such as JSpOC—and coordinating handoffs to other SSN sites. Sensor Site One construction on the Kwajalein Atoll is in progress and nearing completion. The Operations Center in Huntsville, Alabama has been configured and will be integrated with Sensor Site One in the coming months. System hardware, firmware, and software is undergoing integration testing at the Mooretown, NJ ITB and will be deployed at Sensor Site One and the Operations Center. The preliminary design for Sensor Site Two is complete and will provide critical coverage, timeliness, and operational flexibility to the overall system.

    It is necessary to improve human reliability in order to gain a higher reliability of the total plant system taking an account of development of plant automation and improvement of machine reliability. Therefore, the role of the man-machine system will come to be important. Accordingly, the evaluation of the man-machine system design information is desired in order to solve the mismatch problem between plant information presented by the man-machine system and information required by the operator comprehensively. This paper discusses required functions and software framework for the man-machine interface design evaluation system. The man-machine interface design evaluation system has features to extract the potential matters which are inherent on the design information of man-machine system by simulating the operator behavior, the plant system and the man-machine system, considering the operator's cognitive performance and time dependency.

  19. The CANDU man-machine interface and simulator training

    Hinchley, E.M.; Yanofsky, N.

    1982-09-01

    The most significant features of the man-machine interface for CANDU power stations are the extensive use of computer-driven colour graphics displays and the small number of manual controls. The man-machine interface in CANDU stations is designed to present the operator with concise, easy-to-understand information. Future developments in the use of computers in safety shutdown systems, and the use of data highway technologies in plant regulating systems will present special requirements and new opportunities in the application of human factors engineering to the control room. Good man-machine interaction depends on operator training as much as on control room design. In Canada computerized training simulators, which indicate plant response to operator action, are being introducted for operator training. Such simulators support training in normal operation of all plant systems and also in the fault management tasks following malfunctions

    Full Text Available Since May 1992 a small, 915-MHz profiler has been operated continuously in downtown Montreal. It is a five-beam system employing a microstrip array antenna, located atop a 14-story office building that houses several academic departments of McGill University. The data are used for research on precipitation physics and the clear-air reflectivity in addition to wind profiling. We are especially interested in situations in which the reflectivities of the clear air and the precipitation are comparable. This permits the study of interactions between the precipitation and the clear air, a new area of research made possible by wind profilers. On clear days in the summer, 30-min consensus winds can often be measured to an altitude of 3 km, but ground clutter in the antenna sidelobes interferes with measurements below 600 m. Rain when present often permits wind profiling down to 100 m and up to 6 km or higher. On cold winter days there are some periods when the reflectivity is too weak at all levels to permit wind estimation. Falling snow, however, provides readily detectable echoes and serves as a good tracer of the wind and so allows profiling over its full altitude extent. The best conditions for observing interactions between precipitation and the clear air are when light rain falls through a reflective layer associated with a frontal surface or inversion. Unexpectedly, flocks of migrating birds sometimes completely dominate the signal at night in the spring and fall seasons.

    Magnetic configuration of one-way thorsatron VINT-20 is investigated as regards of satisfying the conditions required for the equilibrium of plasma featuring high β (herein β = (nk(Tsub(i) + Tsub(e))/(Bsub(0)sup(2)/18π)). It is revealed that in certain modes which are elaborated at great lateral fields (Bsub(2)/Bsub(0) = -7.5 %), the shape of magnetic surfaces satisfies the requirements to the equilibrium configuration. Values β as estimated from the parameters of the magnetic surface in these favourable modes reach 0.8

  3. Human reliability and the man/machine interface: what do we do after the control room review

    The nuclear industry has focused on only one aspect of the man/machine interface--human factors engineering of control rooms - to enhance nuclear power plant (NPP) safety. There are other factors that profoundly affect the reliability of the operators and maintenance personnel of NPP which, thus, affect NPP safety and availability. This paper discusses the factors of training, selection, job engineering, and work satisfaction, describing the potential effects on reactor safety of these factors at the man/machine interface. The impact of these factors on safety and plant availability is illustrated with examples of results obtained in other fields

    1987-01-01

    A brief history of the development of electrical power systems from the earliest manned space flights illustrates a natural trend toward a growth of electrical power requirements and operational lifetimes with each succeeding space program. A review of the design philosophy and development experience associated with the Space Shuttle Orbiter electrical power system is presented, beginning with the state of technology at the conclusion of the Apollo Program. A discussion of prototype, verification, and qualification hardware is included, and several design improvements following the first Orbiter flight are described. The problems encountered, the scientific and engineering approaches used to meet the technological challenges, and the results obtained are stressed. Major technology barriers and their solutions are discussed, and a brief Orbiter flight experience summary of early Space Shuttle missions is included. A description of projected Space Station power requirements and candidate system concepts which could satisfy these anticipated needs is presented. Significant challenges different from Space Shuttle, innovative concepts and ideas, and station growth considerations are discussed. The Phase B Advanced Development hardware program is summarized and a status of Phase B preliminary tradeoff studies is presented.

  5. Plasma confinement in self-consistent, one-dimensional transport equilibria in the collisionless-ion regime of EBT operation

    1983-01-01

    It has long been recognized that if an EBT-confined plasma could be maintained in the collisionless-ion regime, characterized by positive ambipolar potential and positive radial electric field, the particle loss rates could be reduced by a large factor. The extent to which the loss rate of energy could be reduced has not been as clearly determined, and has been investigated recently using a one-dimensional, time-dependent transport code developed for this purpose. We find that the energy confinement can be improved by roughly an order of magnitude by maintaining a positive radial electric field that increases monotonically with radius, giving a large ExB drift near the outer edge of the core plasma. The radial profiles of heat deposition required to sustain these equilibria will be presented, and scenarios for obtaining dynamical access to the equilibria will be discussed

  6. REMO poor man's reanalysis

    Ries, H.; Moseley, C.; Haensler, A.

    2012-04-01

    Reanalyses depict the state of the atmosphere as a best fit in space and time of many atmospheric observations in a physically consistent way. By essentially solving the data assimilation problem in a very accurate manner, reanalysis results can be used as reference for model evaluation procedures and as forcing data sets for different model applications. However, the spatial resolution of the most common and accepted reanalysis data sets (e.g. JRA25, ERA-Interim) ranges from approximately 124 km to 80 km. This resolution is too coarse to simulate certain small scale processes often associated with extreme events. In addition, many models need higher resolved forcing data ( e.g. land-surface models, tools for identifying and assessing hydrological extremes). Therefore we downscaled the ERA-Interim reanalysis over the EURO-CORDEX-Domain for the time period 1989 to 2008 to a horizontal resolution of approximately 12 km. The downscaling is performed by nudging REMO-simulations to lower and lateral boundary conditions of the reanalysis, and by re-initializing the model every 24 hours ("REMO in forecast mode"). In this study the three following questions will be addressed: 1.) Does the REMO poor man's reanalysis meet the needs (accuracy, extreme value distribution) in validation and forcing? 2.) What lessons can be learned about the model used for downscaling? As REMO is used as a pure downscaling procedure, any systematic deviations from ERA-Interim result from poor process modelling but not from predictability limitations. 3.) How much small scale information generated by the downscaling model is lost with frequent initializations? A comparison to a simulation that is performed in climate mode will be presented.

    1987-01-01

    The field of man-machine systems is introduced with its subareas and a short outline of its history of 45 years. Three current lines of development in university and industrial research are emphasized. Today, the human problem solving activities are experimentally investigated and analytically described more vigorously than the control activities. Further, improved information presentations and decision support are made possible through new technologies of computer graphics and expert systems. At last, work on a general design methodology for man-machine systems is in progress. The aim is to better support human operators of dynamic technological systems as well as designers of graphics for visual display units and of dialogue styles. Thereby, safety and availability of the complete system can be increased. (orig.) [de

  9. Program encourages use of renewable energies in Algeria-20 co-operative projects by sonelgaz in one year

    The renewable energy projects are tools for the management of reserves and sustainable development of desert communities. These are generally areas wher a diesel or gas-powered generator present a problem of fuel transportation and may potentially harm the environment. Tremendous opportunities exist in Algeria for growth in the use of renewable energy technologies in particular photovoltaic solar power. According to some estimates, more than five million Algerians do not have access to grid electricity, while many rural communities are in need of drinking water and water for livestock or irrigation. Given Algerian's abundant solar resource, these rural needs represent a potential market for renewable energy technologies. Nowadays a growing number of people in the south of Algeria are using renewable energy to irrigate their land, light their houses, pump well water and then improve their lives, thanks to the 'Ministere de l'Energie et des Mines' and the Sonelgaz (Societe Nationale de l'Electricite et du Gaz) R and D office. From 1999 up 2002. Sonelgaz Renewable Energy Program, and the above mentioned ministry have collaborated and sponsored several photovoltaic projects in 20 villages of the desert of Algeria concerning this renewable energy program aiming at increasing the use of renewable energy technologies, thus providing green power to isolated villages. Sonelgaz's role in the project is to initiate renewable energy pilot projects that could be easily replicated by area residents and provide training with technical assistance. Based on its feasibility, potential projecs are initially identified and selected by the Sonelgaz R and D office which develops system requirements, provides technical review, evaluates and monitors the projects following their installation. Since 1999, Sonelgaz has received 988 millions of DA (Algerian Dinars) to operate the program. Most activities focus on house lighting and implementing water pumping systems. For most of these

    We designed a new naphthalenetetracarboxylic diimide (NTCDI) semiconductor molecule with long fluoroalkylbenzyl side chains. The side chains, 1.2 nm long, not only aid in self-assembly and kinetically stabilize injected electrons but also act as part of the gate dielectric in field-effect transistors. On Si substrates coated only with the 2 nm thick native oxide, NTCDI semiconductor films were deposited with thicknesses from 17 to 120 nm. Top contact Au electrodes were deposited as sources and drains. The devices showed good transistor characteristics in air with 0.1-1 μA of drain current at 0.5 V of V(G) and V(DS) and W/L of 10-20, even though channel width (250 μm) is over 1000 times the distance (20 nm) between gate and drain electrodes. The extracted capacitance-times-mobility product, an expression of the sheet transconductance, can exceed 100 nS V(-1), 2 orders of magnitude higher than typical organic transistors. The vertical low-frequency capacitance with gate voltage applied in the accumulation regime reached as high as 650 nF/cm(2), matching the harmonic sum of capacitances of the native oxide and one side chain and indicating that some gate-induced carriers in such devices are distributed among all of the NTCDI core layers, although the preponderance of the carriers are still near the gate electrode. Besides demonstrating and analyzing thickness-dependent NTCDI-based transistor behavior, we also showed <1 V detection of dinitrotoluene vapor by such transistors.

    He was sitting on a large slab of rock. As he looked at the cloud of dust hanging hazily on the horizon, the piece of antler and the block of flint he held in his hand hung as if they were suspended from their previous rapid motion. The man gazed intently across the swaying grass which rose in wave-like billows across the distant hills. What was that dust - a herd of buffalo, a band of hunters, or were coyotes chasing the antelope again? After watching for a while he started again to chip the flint with a rapid twisting motion of the bone in his right hand. The little chips of flint fell in the grass before him. It is the same hill but the scene has changed. Seated on the same rock, holding the reins of a saddle horse, a man dressed in buckskin took the fur cap off his head and wiped his brow. He was looking intently across a brown and desolate landscape at a cloud of dust on the far horizon. Was it the hostile tribe of Indians? It could be buffalo. Nervously he kicked at the ground with the deerhide moccasin, pushing the flint chips out of the way. He wiped the dust from his long rifle. What a terrible place - no water, practically no grass, everything bare and brown. Now at sunset, slanting across the hills green with springtime, a cowman sits on a big rock, pushes his sombrero back on his head, and looks across the valley at a large but quiet herd of stock, moving slowly as each steer walks from one lush patch of grass to another, nibbling. Suddenly he stood up. Far on the horizon some dark objects were moving. Is it the sheepmen? Could it be the stage coach from Baggs to the Sweetwater Crossing?Same hill - a gray truck was grinding slowly toward the summit. It pulled up near a small fenced enclosure where there were some instruments painted a bright silver color. A man stepped out of the truck and turned to his younger companion, "You've never found an arrowhead? Maybe you have never thought about it correctly. If you want to find where an Indian camped long

    Eliminating middlemen from security protocols helps less than one would think. EMV electronic payments, for example, can be made fairer by adding an electronic attorney - a middleman which mediates access to a customer’s card. We compare middlemen in crypto protocols and APIs with those in the real world, and show that a man-in-the-middle defence is helpful in many circumstances. We suggest that the middleman has been unfairly demonised.

  19. Man-machine interface versus full automation

    International Nuclear Information System (INIS)

    Hatton, V.

    1984-01-01

    As accelerators grow in size and complexity of operation there is an increasing economical as well as an operational incentive for the controls and operations teams to use computers to help the man-machine interface. At first the computer network replaced the traditional controls racks filled with knobs, buttons and digital displays of voltages and potentiometer readings. The computer system provided the operator with the extension of his hands and eyes. It was quickly found that much more could be achieved. Where previously it was necessary for the human operator to decide the order of the actions to be executed by the computer as a result of a visual indication of malfunctioning of the accelerator, now the operation is becoming more and more under the direct control of the computer system. Expert knowledge is programmed into the system to help the non-specialist make decision and to safeguard the equipment. Machine physics concepts have been incorporated and critical machine parameters can be optimised easily by the physicists or operators without any detailed knowledge of the intervening medium or of the equipment being controlled. As confidence grows and reliability improves, more and more automation can be added. How far can this process of automation replace the skilled operator. Can the accelerators of tomorrow be run like the ever increasing robotic assembly plants of today. How is the role of the operator changing in this new environment

    The OECD Halden Reactor Project is a jointly financed research programme under the auspices of the OECD - Nuclear Energy Agency with fifteen participating countries. One of the main research topics focuses on man-machine systems. Particular attention is paid to the operator's tasks in the reactor control room environment. The overall objective of the research in this field is to provide a basis for improving today's control rooms through the introduction of computer-based solutions for the effective and safe execution of surveillance and control functions in normal as well as off-normal plant situations. The programme comprises four main activities: the verification and validation of safety critical software systems; man-machine interaction research emphasizing improvements in man-machine interfaces on the basis of human factors studies; computerised operator support systems assisting the operator in fault detection/diagnosis and planning of control actions; and control room development providing a basis for retrofitting of existing control rooms and for the design of advanced concepts

The method is illustrated for a single j-shell, where phonons built with one type of particles are introduced. The eigenvalues obtained within the space spanned by the phonons of lowest angular momentum are compared to those of the full space. In such a method, the Pauli principle is fully and properly taken into account. ((orig.))

    The functions of man in space have been in a state of constant change since the first manned orbital flight. Initially, the onboard crewmen performed those tasks essential to piloting and navigating the spacecraft. The time devoted to these tasks has steadily decreased and the crewman's time is being allotted to functions other than orbital operations. The evolving functions include added orbital operational capabilities, experimentation, spacecraft maintenance, and fabrication of useful end items. The new functions will include routine utilization of the crewman to extend mission life, satellite retrieval and servicing, remote manipulator systems operations, and piloting of free-flying teleoperator systems. The most demanding tasks are anticipated to be associated with construction of large space structures. The projected changes will introduce innovative designs and revitalize the concepts for utilizing man in space.

The system must recognize spoken commands, and execute the desired tasks, without manual interventions of operators. The range of applications goes from the execution of commands in an industrial plant's control room, to navigation and interaction in virtual environments. Results are reported for isolated word recognition, the isolated words corresponding to the spoken commands. For the pre-processing stage, relevant parameters are extracted from the speech signals, using the cepstral analysis technique, that are used for isolated word recognition, and corresponds to the inputs of an artificial neural network, that performs recognition tasks.

    Wan, Rui; Pang, Xingyuan; Ren, Jun

    2018-02-01

    This case study improves an operative method of ear reconstruction for microtia patients by using a four-layer rib cartilage framework to increase transverse height of the reconstructive ear to a natural level in one operative stage. The procedures of ear reconstruction were conducted from February 2014 to May 2016. The ear framework used in the procedures was fabricated from autologous rib cartilage into a four-layer spliced sculpture. Totally 23 patients with unilateral microtia were willing to be enrolled in this study. After the operation, 23 patients achieved 2.3-2.8 cm transverse height of reconstructed ears, which was basically the same as the normal side. Both patients and their families felt satisfied with the results. Follow-up was performed at 6-16 months after the procedures. Only one case showed significantly lowered transverse height of the reconstructed ear, compared to the normal one. It was due to the sleeping position of the patient (10-year-old boy), which put the reconstructed ear under pressure and reduced the transverse height of the ear. The method of four-layer sculpted autologous rib cartilage ear reconstruction has good clinical effect. It can provide a reconstructed ear that reaches normal transverse height and avoids a third operation to increase the transverse height by rib cartilage transplantation.

These values, permitting adequate choice of protection both at design and operation level, are dependent on the level of annual individual doses. The man-rem value, originating from annual individual doses less than 0.5 rem are estimated to 1 kf. The proposed value is 20 kf for annual individual exposures between 0.5 and 3 rem, and 90 kf for annual individual exposures between 3 and 5 rem. (author) [fr

The results of these studies show that person-related expectations in respect of risk consequences, the possibility of personal influencing control, the severeness of risk consequences and one's own risk propensity play a significant role in the evaluation of risks.

We show that by adjusting the minimum required signal-to-noise ratio the machine-based MRTDs are very similar to the ones obtained with the help of the human observers.

    The operator is ultimately responsible for the safe and economical operation of the plant, and must evaluate the accuracy of any system-recommended action or other output. Decision support systems offer a means to improve the man-machine interface by explicitly supporting operator problem solving, rather than complicating decision-making by the need to request an explanation of the rationale behind an expert system's advice during a high stress situation.

    One of the major pathways of radiological exposure to man from uranium milling operations is through the terrestrial food chain. Studies by various investigators have shown the extent of uptake and distribution of U-238, U-234, Th-230, Ra-226, Pb-210, and Po-210 in plants and animals. These long-lived natural radioisotopes, all nuclides of the uranium decay series, are found in concentrated amounts in uranium mill tailings. Data from these investigations are used to estimate the dose to man from consumption of beef and milk contaminated by the tailings. This dose estimate from this technologically enhanced source is compared with that from average normal dietary intake of these radionuclides from natural sources.

    One of the major pathways of radiological exposure to man from uranium milling operations is through the beef/milk food chain. Studies by various investigators have shown the extent of uptake and distribution of 238U, 234U, 230Th, 226Ra, 210Pb, and 210Po in plants and cattle. These long-lived natural radioisotopes, all nuclides of the uranium decay series, are found in concentrated amounts in uranium mill tailings. In this paper, data from these investigations are used to estimate the dose to man from consumption of beef and milk from cattle that have fed on forage contaminated with the tailings. The estimated doses from this technologically enhanced source are compared with those resulting from average dietary intake of these radionuclides from natural sources.

Comparison of the above data with the Reference Man data of ICRP which was based primarily on Caucasians suggests some differences in the average weight and height of whole body and in the weights of some organs. Hence there appears to be a need for the establishment of Filipino standard man which can be used in the estimation of internal dose commitment of the Filipinos. (author)

    Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason. Thomas Aquinas argues that man is essentially different from animals because man's intellectual processes show evidence of an abstract mechanism not possessed by animals. Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analog...

    The acceptance of technological risks, which is discussed today mainly in the context of large-scale technologies, has become the subject of political argument, of power politics and also of negotiation. Its evaluation and assessment depend not least on the current atmosphere for decisions and the specific subject. Acceptance research - this is one of the central theses of this book - is not (only) a reactive instrument for later fine-tuning after the probability of risk is evident, but can also be more. However, it requires to this end 'cleaner' and more comprehensible methods; the recognition of its viability limits is also necessary. It provides then a possibility for a rational formulation of policies on the basis of a long-standing, and certainly partly superfluous technological-political dialogue. (orig.) [de

    Occupational exposure to swine has been associated with increased Staphylococcus aureus carriage, including antimicrobial-resistant strains, and increased risk of infections. To characterize animal and environmental routes of worker exposure, we optimized methods to identify S. aureus on operations that raise swine in confinement with antibiotics (industrial hog operation: IHO) versus on pasture without antibiotics (antibiotic-free hog operation: AFHO). We associated findings from tested swine and environmental samples with those from personal inhalable air samplers on worker surrogates at one IHO and three AFHOs in North Carolina using a new One Health approach. We determined swine S. aureus carriage status by collecting swab samples from multiple anatomical sites, and we determined environmental positivity for airborne bioaerosols with inhalable and impinger samplers and a single-stage impactor (ambient air) cross-sectionally. All samples were analyzed for S. aureus, and isolates were tested for antimicrobial susceptibility, absence of scn (livestock marker), and spa type. Seventeen of twenty (85%) swine sampled at the one IHO carried S. aureus at >1 anatomical sites compared to none of 30 (0%) swine sampled at the three AFHOs. All S. aureus isolates recovered from IHO swine and air samples were scn negative and spa type t337; almost all isolates (62/63) were multidrug resistant. S. aureus was recovered from eight of 14 (67%) ambient air and two (100%) worker surrogate personal air samples at the one IHO, whereas no S. aureus isolates were recovered from 19 ambient and six personal air samples at the three AFHOs. Personal worker surrogate inhalable sample findings were consistent with both swine and ambient air data, indicating the potential for workplace exposure. IHO swine and the one IHO environment could be a source of potential pathogen exposure to workers, as supported by the detection of multidrug-resistant S. aureus (MDRSA) with livestock-associated spa

    A 75-year-old woman noticed a small mass in the right side breast and consulted our hospital. The results of the detailed examination indicated the synchronous double primary right breast cancer and the same side lung cancer (rS5). One-stage operation from the same skin incision was scheduled. Volume rendering (VR) of computed tomography (CT)-scan was very useful in deciding the position and the length of the skin incision. The breast tumor resection and the right middle lobe resection were successfully performed through 6.5 cm skin incision.

  3. Estimate of man-rem expenditures for a mature CANDU 600 MW(e) station

    1978-08-01

    In recent years, man-rem expenditures at operating stations have come under close scrutiny in order to reduce operating personnel dosage. This increased awareness has led to concerted efforts to improve station design and to improve operating procedures to achieve lower man-rem expenditures. This paper is intended to highlight design improvements that have been made in the CANDU 600 MW(e) design and to show how these improvements will reduce man-rem expenditures. Other considerations, such as station decontaminations of the primary heat transport system and the fuelling machines and stricter chemistry control are presently available to help reduce man-rem consumption. Also, station management operating policy should emphasize man-rem awareness. (author)

  4. Fabrication and operation methods of a one-time programmable (OTP) nonvolatile memory (NVM) based on a metal-oxide-semiconductor structure

    2011-01-01

    In this paper, a novel one-time programmable (OTP) nonvolatile memory (NVM) device and its array based on a metal-insulator-semiconductor (MIS) structure is proposed. The Iindividual memory device has a vertical channel of a silicon diode. Historically, OTP memories were widely used for read-only-memories (ROMs), in which the most basic system architecture model was to store central processing unit (CPU) instructions. By grafting the nanoscale fabrication technology and novel structuring onto the concept of the OTP memory, innovative high-density NVM appliances for mobile storage media may be possible. The program operation is performed by breaking down the thin oxide layer between the pn diode structure and the wordline (WL). The programmed state can be identified by an operation that reads the leakage currents through the broken oxide. Since the proposed OTP NVM is based on neither a transistor structure nor a charge storing mechanism, it is highly reliable and functional for realizing the ultra-large scale integration. The operation physics and the fabrication processes are also explained in detail.

    MAN Nutzfahrzeuge AG (Munich, Federal Republic of Germany) always is eager to offer products for the respective markets whereby the products are interesting for the customer under economic criteria. Additionally, the products shall not lack in the travelling comfort under consideration of the legal emission borders. Thus, a AdBlue {sup registered} free technology for all MAN series was already offered before the legal introduction of EURO IV. This technology is based on an internal-motor solution with external, cooled AGR and a PM-Cat {sup registered} -filter. This solution is esteemed highly by our customers because apart from the well-known advantages in relation to a SCR technology there were no losses with the operating cost. With EURO V which is inserted in some countries MAN Nutzfahrzeuge AG returns to a long-term experience with SCR technology. The motivation for the development of a AdBlue {sup registered} free solution was the positive feedback of our customers on the basis of MAN EURO IV AGR/PM Cat technology. With the developed EURO V AGR solution, other EURO IV solutions in line with market conditions for the 'Emerging markets' can be derived with which a technology without exhaust post-treatment can be offered worldwide for our customers. This technology presents the basis for a platform concept EURO IV/V and EURO VI. In this concept, EURO IV can be presented without subsequent treatment of exhaust gases, EURO V in connection with an Oxicat and EURO VI with a SCRT system. Here, the vehicle/engine concept presents the most important components for the individual series in particular. By means of these components, the goal EURO V was achieved internal-motor without losses of operating cost and life span in relation to SCR technologies.

    Krause, Niklas; Burgel, Barbara; Rempel, David

    2010-01-01

    The literature on psychosocial job factors and musculoskeletal pain is inconclusive in part due to insufficient control for confounding by biomechanical factors. The aim of this study was to investigate prospectively the independent effects of effort-reward imbalance (ERI) at work on regional musculoskeletal pain of the neck and upper extremities of call center operators after controlling for (i) duration of computer use both at work and at home, (ii) ergonomic workstation design, (iii) physical activities during leisure time, and (iv) other individual worker characteristics. This was a one-year prospective study among 165 call center operators who participated in a randomized ergonomic intervention trial that has been described previously. Over an approximate four-week period, we measured ERI and 28 potential confounders via a questionnaire at baseline. Regional upper-body pain and computer use was measured by weekly surveys for up to 12 months following the implementation of ergonomic interventions. Regional pain change scores were calculated as the difference between average weekly pain scores pre- and post intervention. A significant relationship was found between high average ERI ratios and one-year increases in right upper-extremity pain after adjustment for pre-intervention regional mean pain score, current and past physical workload, ergonomic workstation design, and anthropometric, sociodemographic, and behavioral risk factors. No significant associations were found with change in neck-shoulder or left upper-extremity pain. This study suggests that ERI predicts regional upper-extremity pain in -computer operators working >or=20 hours per week. Control for physical workload and ergonomic workstation design was essential for identifying ERI as a risk factor.

  16. Interactive animated displayed of man-controlled and autonomous robots

    International Nuclear Information System (INIS)

    Crane, C.D. III; Duffy, J.

    1986-01-01

    An interactive computer graphics program has been developed which allows an operator to more readily control robot motions in two distinct modes; viz., man-controlled and autonomous. In man-controlled mode, the robot is guided by a joystick or similar device. As the robot moves, actual joint angle information is measured and supplied to a graphics system which accurately duplicates the robot motion. Obstacles are placed in the actual and animated workspace and the operator is warned of imminent collisions by sight and sound via the graphics system. Operation of the system in man-controlled mode is shown. In autonomous mode, a collision-free path between specified points is obtained by previewing robot motions on the graphics system. Once a satisfactory path is selected, the path characteristics are transmitted to the actual robot and the motion is executed. The telepresence system developed at the University of Florida has been successful in demonstrating that the concept of controlling a robot manipulator with the aid of an interactive computer graphics system is feasible and practical. The clarity of images coupled with real-time interaction and real-time determination of imminent collision with obstacles has resulted in improved operator performance. Furthermore, the ability for an operator to preview and supervise autonomous operations is a significant attribute when operating in a hazardous environment

  17. Development of a numerical tool to study the mixing phenomenon occurring during mode one operation of a multi-mode ejector-augmented pulsed detonation rocket engine

    Science.gov (United States)

    Dawson, Joshua

    A novel multi-mode implementation of a pulsed detonation engine, put forth by Wilson et al., consists of four modes; each specifically designed to capitalize on flow features unique to the various flow regimes. This design enables the propulsion system to generate thrust through the entire flow regime. The Multi-Mode Ejector-Augmented Pulsed Detonation Rocket Engine operates in mode one during take-off conditions through the acceleration to supersonic speeds. Once the mixing chamber internal flow exceeds supersonic speed, the propulsion system transitions to mode two. While operating in mode two, supersonic air is compressed in the mixing chamber by an upstream propagating detonation wave and then exhausted through the convergent-divergent nozzle. Once the velocity of the air flow within the mixing chamber exceeds the Chapman-Jouguet Mach number, the upstream propagating detonation wave no longer has sufficient energy to propagate upstream and consequently the propulsive system shifts to mode three. As a result of the inability of the detonation wave to propagate upstream, a steady oblique shock system is established just upstream of the convergent-divergent nozzle to initiate combustion. And finally, the propulsion system progresses on to mode four operation, consisting purely of a pulsed detonation rocket for high Mach number flight and use in the upper atmosphere as is needed for orbital insertion. Modes three and four appear to be a fairly significant challenge to implement, while the challenge of implementing modes one and two may prove to be a more practical goal in the near future. A vast number of potential applications exist for a propulsion system that would utilize modes one and two, namely a high Mach number hypersonic cruise vehicle. There is particular interest in the dynamics of mode one operation, which is the subject of this research paper. Several advantages can be obtained by use of this technology. Geometrically the propulsion system is fairly

We describe a conjugate gradient method for the numerical inversion. Numerical results for one-dimensional models are presented to illustrate the feasibility of the approach. Also we provide a proof of the differentiability of the weak form with respect to the coefficient as well as the continuity and boundedness of the linearized operator under reasonable assumptions using the maximal parabolic regularity theory. © 2012 Elsevier B.V.

    Tsvetkova, Galina V.; Peddicord, Kenneth L.

    2002-01-01

    Promising existing nuclear reactor concepts together with new ideas are being discussed worldwide. Many new studies are underway in order to identify prototypes that will be analyzed and developed further as systems for Generation IV. The focus is on designs demonstrating full inherent safety, competitive economics and proliferation resistance. The work discussed here is centered on a modularized small-size High Temperature Gas-cooled Reactor (HTGR) concept. This paper discusses the possibility of maintaining long-term operation on one fuel loading through utilization of plutonium and higher actinides in the small-size pebble-bed reactor (PBR). Acknowledging the well-known flexibility of the PBR design with respect to fuel composition, the principal limitations of the long-term burning of plutonium and higher actinides are considered. The technological challenges and further research are outlined. The results allow the identification of physical features of the PBR that significantly influence flexibility of the design and its applications. (authors)

    2012-08-01

    Two most frequent asymptomatic diseases qualifying for vascular surgery are abdominal aortic aneurysm (AAA) and internal carotid artery stenosis (ICAS). Emotions experienced by the patient activate processes of dealing with the cognitive dissonance of asymptomatic disease. The aim of this paper was to compare the reasons involved in decision making on surgery in two asymptomatic vascular pathologies. Fifty patients were divided into two groups: the ICAS group-27 (CAS or CEA) and the AAA group-23 (EVAR or open surgical operation (OSR). Specific questionnaire regarding: 1) self-image; 2) attitude to one's illness; 3) reasons for decision on surgery was applied for the study. The χ² test was used to for the analysis. The AAA patients reacted emotionally (88.2%) comparing to ICAS patients reacting "rationally" (59.3%) (α=0.05). In AAA patients attitude towards themselves had worsened (α=0.001) AAA patients were less likely to seek support in decision on surgery (α=0.01). ICAS patients are internally motivated (78.7%), whereas AAA patients are externally motivated (63.9%) (α=0.001). Reasons underlying the decision on surgery, were predominantly rational (55.8%). In the process of decision-making on surgery by asymptomatic patients, evolutionary transformation takes place - the emotional attitude to one's illness leads to rationally evaluated decision. Regardless of the causes the process of making a decision on surgical operation tended to run more smoothly in ICAS patients. The ICAS patients tended to display a rational attitude to their illness. AAA patients displayed a distinctly emotional attitude towards their illness.

    2015-01-01

    Purpose: We have developed a gated spot scanning proton beam therapy system with real-time tumor-tracking. This system has the ability of multiple-gated irradiation in a single synchrotron operation cycle controlling the wait-time for consecutive gate signals during a flat-top phase so that the decrease in irradiation efficiency induced by irregular variation of gate signal is reduced. Our previous studies have shown that a 200 ms wait-time is appropriate to increase the average irradiation efficiency, but the optimal wait-time can vary patient by patient and day by day. In this research, we have developed an evaluation system of the optimal wait-time in each irradiation based on the log data of the real-time-image gated proton beam therapy (RGPT) system. Methods: The developed system consists of logger for operation of RGPT system and software for evaluation of optimal wait-time. The logger records timing of gate on/off, timing and the dose of delivered beam spots, beam energy and timing of X-ray irradiation. The evaluation software calculates irradiation time in the case of different wait-time by simulating the multiple-gated irradiation operation using several timing information. Actual data preserved in the log data are used for gate on and off time, spot irradiation time, and time moving to the next spot. Design values are used for the acceleration and deceleration times. We applied this system to a patient treated with the RGPT system. Results: The evaluation system found the optimal wait-time of 390 ms that reduced the irradiation time by about 10 %. The irradiation time with actual wait-time used in treatment was reproduced with accuracy of 0.2 ms. Conclusion: For spot scanning proton therapy system with multiple-gated irradiation in one synchrotron operation cycle, an evaluation system of the optimal wait-time in each irradiation based on log data has been developed.

    1994-01-01

    Gas turbine driven gas compressors have been widely used on manned offshore facilities. Similarly unmanned gas turbine driven compressor stations have been in operation onshore with major gas transmission companies in Europe, North America and elsewhere. This paper summarizes a recent joint industry study to investigate the technical and economic feasibility of Not Normally Manned (NNM) Offshore Compression Facilities in terms of reliability, availability and maintainability. Classification of not normally manned (or unmanned) offshore facilities in the UK North Sea is in accordance with HSE Operations Notice 8. ON8 specifies criteria for offshore visits, visit hours and number of personnel on board for the operation of NNM platforms. This paper describes a typical Southern North Sea gas platform being considered for NNM compressor application. The conclusions from the study was that NNM compression is technically feasible with the facilities being able to provide an availability in excess of 98%. Life cycle costs were of the order of 70% of manned facilities thus significantly improving field development economics

    A preliminary feasibility study of the potential application of small nuclear reactor space power systems to manned planetary surface base missions was conducted. The purpose of the study was to identify and assess the technology, performance, and safety issues associated with integration of reactor power systems with an evolutionary manned planetary surface exploration scenario. The requirements and characteristics of a variety of human-rated modular reactor power system configurations selected for a range of power levels from 25 kWe to hundreds of kilowatts is described. Trade-off analyses for reactor power systems utilizing both man-made and indigenous shielding materials are provided to examine performance, installation and operational safety feasibility issues. The results of this study have confirmed the preliminary feasibility of a wide variety of small reactor power plant configurations for growth oriented manned planetary surface exploration missions. The capability for power level growth with increasing manned presence, while maintaining safe radiation levels, was favorably assessed for nominal 25 to 100 kWe modular configurations. No feasibility limitations or technical barriers were identified and the use of both distance and indigenous planetary soil material for human rated radiation shielding were shown to be viable and attractive options.

    Full Text Available Background: With the increasing number of cases for CABG, the cardiac rehabilitation has gained importance. The trends in rehabilitation of a coronary artery disease patient are changing by incorporating a variety of aerobic exercises and resisted training in to their rehabilitation program. The outcome of any exercise chiefly depends on the training parameters like intensity, frequency and duration. Hence the present study focused to know the effects of supervised moderate intensity exercises on patients during hospital discharge following CABG. The objective of is to study the effectiveness of supervised moderate intensity exercise on distance walked and Quality of Life at hospital discharge following CABG. Methods: Study recruited randomly 46 patients between age group 40-65 years who were posted for non-emergency CABG for the first time. Pre-operative assessment was done thoroughly and was divided in to two groups, Group A conventional treatment and Group B Moderate intensity exercise group. The patients were treated using different protocols in terms of intensity for 8-10 days immediate post CABG. Then the outcome parameters of 6MWT and sf-36 were compared for analysis. Results: Both groups individually showed extremely significant results for two outcome measures. 6 MWD difference between two treatment groups showed significant results with unpaired t test (t = 8.5720,p<0.001. Quality of life score difference within group showed very significant results but there is no difference found between both groups. Conclusion: Moderate intensity exercises can also be included in the immediate post-operative phase of CABG, as they reduce the length of hospital stay and quicken the cardiac rehabilitation process. But there need to be a lot of randomized control trails to confirm the benefits of moderate intensity exercises in phase one rehabilitation program after CABG.

  11. A distributed planning concept for Space Station payload operations

    Hagopian, Jeff; Maxwell, Theresa; Reed, Tracey

    1994-01-01

    The complex and diverse nature of the payload operations to be performed on the Space Station requires a robust and flexible planning approach. The planning approach for Space Station payload operations must support the phased development of the Space Station, as well as the geographically distributed users of the Space Station. To date, the planning approach for manned operations in space has been one of centralized planning to the n-th degree of detail. This approach, while valid for short duration flights, incurs high operations costs and is not conducive to long duration Space Station operations. The Space Station payload operations planning concept must reduce operations costs, accommodate phased station development, support distributed users, and provide flexibility. One way to meet these objectives is to distribute the planning functions across a hierarchy of payload planning organizations based on their particular needs and expertise. This paper presents a planning concept which satisfies all phases of the development of the Space Station (manned Shuttle flights, unmanned Station operations, and permanent manned operations), and the migration from centralized to distributed planning functions. Identified in this paper are the payload planning functions which can be distributed and the process by which these functions are performed.

  12. The strangest man. The hidden life of Paul Dirac

    International Nuclear Information System (INIS)

    Farmelo, Graham

    2016-01-01

    The Strangest Man is the Costa Biography Award-winning account of Paul Dirac, the famous physicist sometimes called the British Einstein. He was one of the leading pioneers of the greatest revolution in twentieth-century science: quantum mechanics. The youngest theoretician ever to win the Nobel Prize for Physics, he was also pathologically reticent, strangely literal-minded and legendarily unable to communicate or empathize. Through his greatest period of productivity, his postcards home contained only remarks about the weather. Based on a previously undiscovered archive of family papers, Graham Farmelo celebrates Dirac's massive scientific achievement while drawing a compassionate portrait of his life and work. Farmelo shows a man who, while hopelessly socially inept, could manage to love and sustain close friendship. The Strangest Man is an extraordinary and moving human story, as well as a study of one of the most exciting times in scientific history.

  13. One Medicine, One Acupuncture

    Full Text Available “One Acupuncture”, like “One Medicine”, has the potential to improve research quality and clinical outcomes. However, while human acupuncture point locations have remained largely consistent over time, the veterinary versions remain imprecise and variable. Establishing anatomical criteria for veterinary acupuncture atlases in keeping with the human template will create congruence across species, benefiting both research and practice. Anatomic criteria for points based on objectively verifiable structures will facilitate translational research. Functionally comparative innervation, in particular, should be similar between species, as the nerves initiate and mediate physiologic changes that result from point stimulation. If researchers choose points that activate different nerves in one species than in another, unpredictable outcomes may occur. Variability in point placement will impede progress and hamper the ability of researchers and clinicians to make meaningful comparisons across species. This paper reveals incongruities that remain between human and veterinary acupuncture points, illustrating the need to analyze anatomical characteristics of each point to assure accuracy in selecting transpositional acupuncture locations.

    The available evidence on the effects of radiation on man and the predictions that have been made of possible low level effects are reviewed. Data from United Nations Scientific Committee of the Effects of Atomic Radiation (UNSCEAR) and the committee on the Biological Effects of Ionising Radiation (BEIR) is used to illustrate the acute, delayed and hereditary effects of high dose levels. The effects of low dose levels are discussed on the assumption that both somatic and hereditary effects can be predicted on the basis of linear extrapolation from high dose effects. (U.K.)

  16. Psychological considerations of man in space: Problems & solutions

    Science.gov (United States)

    Kass, J.; Kass, R.; Samaltedinov, I.

    With concrete plans for long duration flight taking form a new impetus is lent to preparing man for this hostile and unnatural environment. Cramped conditions, isolation from family and loved ones, work stress, fear, and incompatibility with fellow crew, are but a few of the problems suffered by astronauts and cosmonauts during their long missions in orbit about the earth. Although criteria for selection of crew is one aspect of attacking the problem, it has not solved it Notwithstanding good selection, team combination, and counselling before flight, problems have still occurred with unwanted consequences. Incompatibility of team members, far from being the exception, has been frequent. This has been detrímental both physiologically and psychologically for the individual as well as for the operational success and safety of the missions. Because problems will inevitably occur in future long duration missions, especially when they are of international and multi-cultural nature, the importance of dealing with them is underlined. This paper takes a different approach towards ameliorating these problems, namely that of psychological group training before a mission.

    To investigate the methods and effectiveness of one-stage operation for pelvis and acetabular fractures combined with Morel-Lavallée injury by internal fixation associated with vacuum sealing drainage (VSD). Between June 2008 and October 2012, 15 cases of pelvis and acetabular fractures combined with Morel-Lavallée injury were treated. There were 5 males and 10 females, aged from 18 to 67 years (mean, 36.8 years). Fractures were caused by traffic accident in 11 cases and crashing injury of heavy object in 4 cases. The time from injury to hospitalization was 3 hours to 9 days (mean, 5.4 days). Morel-Lavallée injury located in the above posterior superior iliac spine in 4 cases, greater trochanter in 7 cases, and anterior proximal thigh in 4 cases. In 10 cases complicated by pelvic fracture, there were 1 case of anteroposterior compression type, 3 cases of lateral compression type, 5 cases of vertical shear type, and 1 case of compound injury type; in 5 cases complicated by acetabular fracture, there were 1 case of transverse fracture, 1 case of posterior wall and posterior column fracture, 1 case of transverse acetabulum plus posterior wall fracture, and 2 cases of both columns fracture. Open reduction and internal fixation were used to treat pelvic and acetabular fractures, and VSD to treat Morel-Lavallée injury. When the drainage volume was less than 20 mL/d, interrupted wound suture or free skin grafting was performed. The hospitalization time was 16-31 days (mean, 20.8 days). Thirteen cases were followed up 4-16 months (mean, 7.8 months). The healing time of Morel-Lavallée injury was 16-36 days after operation (mean, 21.3 days). All the wounds had primary healing, and no infection occurred. The X-ray films showed that all fractures healed, with a mean healing time of 13.6 weeks (range, 11-18 weeks). At 6.5 months after operation, according to Majeed function scoring system in 8 cases of pelvic fracture, the results were excellent in 5 cases, good in 2 cases

    2008-08-01

    In 2002 the Australian Parliament enacted legislation which prohibited both therapeutic and reproductive embryonic cloning. Just four years later, in December 2006, this same legislation was amended, reversing the prohibition on therapeutic cloning, while retaining the ban on reproductive cloning. The Prime Minister, sensing the political mood, allowed a conscience vote. This contrasted with his decision several months earlier against introducing any changes to the 2002 Act, despite 54 recommendations having been made by a Statutory Review Committee. Approval of the legislation had as much to do with the careful drafting of the provisions as with any rational, social or scientific factor. The legislation is narrow in scope, retains an absolute prohibition on reproductive cloning and contains strict regulations with heavy criminal penalties. The Act requires a review after three years. A number of questions remain. Does stem cell research demand a global rather than a local approach, by way of an international Covenant? Does the legal status of a cloned embryo need further examination? Will the embryo have a separate legal standing recognised by law? These are some of the questions which will need addressing as the law tries to keep up with science.

    Allocating limited resource efficiently is a task to which efficient planning and policy design aspires. This may be a non-trivial task. For example, the seventh sustainable development goal (SDG) of Agenda 2030 is to provide access to affordable sustainable energy to all. On the one hand, energy is required to realise almost all other SDGs. (A clinic requires electricity for fridges to store vaccines for maternal health, irrigate agriculture requires energy to pump water to crops in dry periods etc.) On the other hand, the energy system is non-trivial. It requires the mapping of resource, its conversion into useable energy and then into machines that we use to meet our needs. That requires new tools that draw from standard techniques, best-in-class models and allow the analyst to develop new models. Thus we present the Model Management Infrastructure (MoManI). MoManI is used to develop, manage, run, store input and results data for linear programming models. MoManI, is a browser-based open source interface for systems modelling. It is available to various user audiences, from policy makers and planners through to academics. For example, we implement the Open Source energy Modelling System (OSeMOSYS) in MoManI. OSeMOSYS is a specialized energy model generator. A typical OSeMOSYS model would represent the current energy system of a country, region or city; in it, equations and constraints are specified; and calibrated to a base year. From that future technologies and policy options are represented. From those scenarios are designed and run. Efficient allocation of energy resource and expenditure on technology is calculated. Finally, results are visualized. At present this is done in relatively rigid interfaces or via (for some) cumbersome text files. Implementing and operating OSeMOSYS in MoManI shortens the learning curve and reduces phobia associated with the complexity of computer modelling, thereby supporting effective capacity building activities.

    Building manned lunar base is one of the core aims of human lunar exploration project, which is also an important way to carry out the exploitation and utilization of lunar in situ resources. The most important part of manned lunar base is the design and construction of living habitation and many factors should be considered including science objective and site selection. Through investigating and research, the scientific goals of manned lunar base should be status and characteristics ascertainment of lunar available in situ resources, then developing necessary scientific experiments and utilization of lunar in situ resources by using special environment conditions of lunar surface. The site selection strategy of manned lunar base should rely on scientific goals according to special lunar surface environment and engineering capacity constraints, meanwhile, consulting the landing sites of foreign unmanned and manned lunar exploration, and choosing different typical regions of lunar surface and analyzing the landform and physiognomy, reachability, thermal environment, sunlight condition, micro meteoroids protection and utilization of in situ resources, after these steps, a logical lunar living habitation site should be confirmed. This paper brings out and compares three kinds of configurations with fabricating processes of manned lunar base, including rigid module, flexible and construction module manned lunar base. 1.The rigid habitation module is usually made by metal materials. The design and fabrication may consult the experience of space station, hence with mature technique. Because this configuration cannot be folded or deployed, which not only afford limit working and living room for astronauts, but also needs repetitious cargo transit between earth and moon for lunar base extending. 2. The flexible module habitation can be folded in fairing while launching. When deploying on moon, the configuration can be inflatable or mechanically-deployed, which means under

  3. The rights of man and animal experimentation.

    Science.gov (United States)

    Martin, J

    1990-01-01

    Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason. Thomas Aquinas argues that man is essentially different from animals because man's intellectual processes show evidence of an abstract mechanism not possessed by animals. Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analogy. However, cruelty to animals is illicit and they should be protected, principally not because they have rights, but because he who is cruel to animals is more likely to be cruel to his fellowman. If there is a need for animal experimentation in science for the good of man, this approach gives philosophical justification for experimentation, since man's well-being must come before that of animals because of his unique possession of rights. However, those experiments should be carried out in the kindest way possible, to promote kindness towards man. To see man as solely part of a biological continuum in competition for rights with those beings close to him biologically, detracts from man's dignity. PMID:2135948

    One of the critical determinants of performance for any remotely operated maintenance system is the compatibility achieved between elements of the man/machine interface (e.g., master manipulator controller, controls, displays) and the human operator. In the remote control engineering task of the Consolidated Fuel Reprocessing Program, considerable attention has been devoted to optimizing the man/machine interface of the operator control station. This system must be considered an integral element of the overall maintenance work system which includes transporters, manipulators, remote viewing, and other parts. The control station must reflect the integration of the operator team, control/display panels, manipulator master controllers, and remote viewing monitors. Human factors principles and experimentation have been used in the development of an advanced integrated operator control station designed for the advance servomanipulator. Key features of this next-generation design are summarized in this presentation. 7 references, 4 figures

    In recent years, there has been a major shift in emphasis within neurology from being a largely diagnostic discipline to one much more actively involved in treating disease. There have been major scientific advances leading to new and effective treatments. There is also a much greater awareness of the burden of neurological disease (Olesen J, Leonardi M. European Journal of Neurology 2003; 10: 471) and informed sufferers are requesting specific intervention. There is wide variation in the delivery of neurological services throughout Europe. This is reflected in manpower levels, the place of neurology related to other medical specialties and different mixes of hospital and private office practice. These differences have been thrown into sharper focus by the recent expansion of the European Union (EU). Initial training in neurology is given to undergraduate/pre-graduate students. Post-graduate education is delivered within a residency program leading to specialist qualification and certification. We now recognize that this is only the beginning of a life long program of continuous education and development (CME/CPD). National and international exchange programs facilitate the growth of knowledge and promote professional harmony and cooperation. The free migration of medical specialists has been an aspiration but remains limited by cultural, linguistic, personal, professional, political and economic factors. Two bodies, the European Board of Neurology (EBN-UEMS) http://www.uems-neuroboard.org (Union Européenne des Médecins Spécialistes) and the European Federation of Neurological Societies (EFNS) http://www.efns.org are actively involved in harmonising and developing neurology at the European level.

It is necessary to adopt the state of the art technologies to present and make bi-directional the interaction of users with cultural heritage objects. In this work, we present two different applications of novel technologies applied to the Vitruvian man of Leonardo. The first application is the mirror that exploits a 3D depth sensor to compare the proportions of a user with the perfect ones of the Vitruvian man. The second application is a complex interaction between a complete novel 3D model of the Leonardo’s Vitruvian Man, sounds and image effects inside a 360-degrees hologram. These two systems are the results of interaction between academia and the 3D EVE spin-off company.

Habituation is common in experimental pain models, and dividing analgesics and placebo evenly between the study days is one way of eliminating the effects......Human experimental pain models are important tools in pain research. The primary aims of pain research in normal man is 1) to provide insight in pain mechanisms, 2) to provide a rational basis for clinical trials of pain relieving interventions, and 3) to confirm the anti-nociceptive effects...... demonstrated in animal models. Most often clinical pain is due to tissue damage leading to acute inflammation and hyperalgesia, but only few human pain models have examined pain responses in injured tissues. Therefore, models with controlled and reversible tissue trauma are needed. The human burn model...

    1981-10-01

    This paper provides an elementary discussion of the problems of verification and validation in the context of the empirical evaluation of designs for man-machine systems. After a definition of the basic terms, a breakdown of the major parts of the process of evaluation is given, with the purpose of indicating where problems may occur. This is followed by a discussion of verification and validation, as two distinct concepts. Finally, some of the practical problems of ascertaining validity are discussed. The general conclusion is that rather than rely blindly on a well-established procedure or rule, one should pay attention to the meaningfulness of the aspects which are selected for observation, and the degree of systematism of the methods of observation and analysis. A qualitative approach is thus seen as complementary to a quantitative approach, rather than antithetical to it. (author)

Tesla not only discovered the rotating magnetic field, the basis of most alternating current machinery, but also introduced the fundamentals of robotry, computers, and missile science and helped pave the way for such technologies as satellites, microwaves, beam weapons, and nuclear fusion. Almost supernaturally gifted, Tesla was also unusually erratic, flamboyant, and neurotic. He was J. P. Morgan's client, counted Mark Twain as a friend, and considered Thomas Edison an enemy. But above all, he was the hero and mentor to many of the last century's most famous scientists. In a meticulously researched, engagingly written biography, Margaret Cheney presents the many different dimensions of this extraordinary man, capturing his human qualities and quirks as she chronicles a lifetime of discoveries that continue to alter our ...

  15. Deformation of Man Made Objects

    KAUST Repository

    Ibrahim, Mohamed

    2012-07-01

    We introduce a framework for 3D object deformation with primary focus on man-made objects. Our framework enables a user to deform a model while preserving its defining characteristics. Moreover, our framework enables a user to set constraints on a model to keep its most significant features intact after the deformation process. Our framework supports a semi-automatic constraint setting environment, where some constraints could be automatically set by the framework while others are left for the user to specify. Our framework has several advantages over some state of the art deformation techniques in that it enables a user to add new features to the deformed model while keeping its general look similar to the input model. In addition, our framework enables the rotation and extrusion of different parts of a model.

    Various concepts for advanced manned launch systems are examined for delivery missions to space station and polar orbit. Included are single-and two-stage winged systems with rocket and/or air-breathing propulsion systems. For near-term technologies, two-stage reusable rocket systems are favored over single-stage rocket or two-stage air-breathing/rocket systems. Advanced technologies enable viable single-stage-to-orbit (SSTO) concepts. Although two-stage rocket systems continue to be lighter in dry weight than SSTO vehicles, advantages in simpler operations may make SSTO vehicles more cost-effective over the life cycle. Generally, rocket systems maintain a dry-weight advantage over air-breathing systems at the advanced technology levels, but to a lesser degree than when near-term technologies are used. More detailed understanding of vehicle systems and associated ground and flight operations requirements and procedures is essential in determining quantitative discrimination between these latter concepts.

  17. Man-machine interaction in Canadian nuclear power plants

    Olmstead, R.A.

    1994-01-01

    The design of man-machine interaction in the CANDU plants has evolved considerably over several generations of plants, from the first Douglas Point plant through to the next generation of plants represented by new designs like CANDU 3. In the early plants, the control room configuration was based on designers' projections of control interface requirements. With succeeding generations of designs, there has been an evolution towards a more systematic consideration of human strengths and weaknesses, increasing attention to formal requirements definition, and incorporation of a larger base of operational experience. This paper describes the design of the man-machine interaction for third generation CANDU-3 control rooms for improved operator reliability and reduced costs. (author). 13 refs., 3 figs

    Stratton, R.C.; Lusk, E.L.

    1983-01-01

    This paper describes a project being undertaken at Argonne National Laboratory to demonstrate the usefulness of automated reasoning techniques in the implementation of a man-machine control system being designed at the EBR-II nuclear power plant. It is shown how automated reasoning influences the choice of optimal roles for both man and machine in the system control process, both for normal and off-normal operation. In addition, the requirements imposed by such a system for a rigorously formal specification of operating states, subsystem states, and transition procedures have a useful impact on the analysis phase. The definitions and rules are discussed for a prototype system which is physically simple yet illustrates some of the complexities inherent in real systems

  19. Man's limitations. The Catholic view.

    The Assistant Bishop of Manila, Philippines, comments on Pope John Paul II teachings and former Pope Paul VI's Humanae Vitae. The Roman Catholic Church over the past twenty five years has not accepted modern contraception. Lay Catholics are confused over the appropriate behavior regarding family planning, are ignorant of the Church's teachings, or have followed their conscience. Critics say that the teachings are obsolete and unheeded. Church officials respond that the Church is run by divine inspiration and not majority rule. The Church position is based on reason and on God himself, who prohibits man-made contraception. Paul VI revealed that the conjugal act was the link between unitive and procreative meanings, and man did not have the right to break the link on his own initiative. John Paul II reaffirms this position by stating that human beings do not have "absolute dominion over the conjugal act" and are not the final arbiters of the creation of life. Humans are servants of the creation of new life as collaborators and procreators. Humans act like Gods when they deprive the conjugal act of procreative meaning through contraceptive use. Natural family planning does not violate this divine prerogative. The Pope's teachings are verified. There is evidence of declines in conjugal infidelity, the lowering of moral standards, increased abortion, and the demise of demographic imperialism. The Church recognizes the problem of overpopulation, and the Catholic Bishops Conference of the Philippines acknowledges the responsibility of all sectors of society to solve the problem. Catholics in the Philippines are opposed to the Ramos' administration's aggressive birth control program. The opposition is due to the government's lack of provision of sufficient information about the side effects of modern contraceptives and the neglect of natural family planning, which is the only morally legitimate form of contraception sanctioned by Roman Catholics. Freedom of choice means

  20. Biosafety in manned space flight

    2006-01-01

    The main goal of manned exploration is to achieve a prolonged stay in space, for example in an orbital station (such as the International Space Station (ISS)) or in planetary bases on the Moon and/or Mars. It goes without saying that such missions can only be realized when the astronaut's health and well-being is secured. In this respect, the characterization of the microbiological contamination on board spacecraft and orbital stations and the influence of cosmic radiation and microgravity are of paramount importance. Microbial contamination may originate from different sources and includes the initial contamination of space flight materials during manufacturing and assembly, the delivery of supplies to the orbital station, the supplies themselves, secondary contamination during the lifetime of the orbital station, the crew and any other biological material on board e.g. animals, plants, micro-organisms used in scientific experiments. Although most microorganisms do not threaten human health, it has been reported that in a confined environment, such as a space cabin, microorganisms may produce adverse effects on the optimal performance of the space crew and the integrity of the spacecraft or habitat. These effects range from infections, allergies, and toxicities to degradation of air and water supplies. Biodegradation of critical materials may result in system failure and this may jeopardize the crew. The research aims at monitoring the biological airborne and surface contamination during manned space flight. The ISS has been selected as primary test bed for this study. The majority of the investigations are being done by the Russian Institute of Biomedical Problems (IBMP), which is responsible for monitoring the biological contamination in the habitable compartments of the ISS for safety and hygienic reasons. Within the frame of a collaboration between IBMP and the European Space Agency (ESA), SCK-CEN is able to participate in the analyses

    The immobilization of naringinase in PVA lens-shaped particles, a cheap and biocompatible hydrogel was shown to provide an effective biocatalyst for naringin hydrolysis, an appealing reaction in the food and pharmaceutical industries. The present work addresses the operational stability and scale-up of the bioconversion system, in various types of reactors, namely shaken microtiter plates (volume ⩽ 2 mL), batch stirred tank reactors (volume reactor (PBR, 6.8 mL). Consecutive batch runs were performed with the shaken/stirred vessels, with reproducible and encouraging results, related to operational stability. The PBR was used to establish the feasibility for continuous operation, running continuously for 54 days at 45°C. The biocatalyst activity remained constant for 40 days of continuous operation. The averaged specific productivity was 9.07 mmol h(-1) g enzyme(-1) and the half-life of 48 days. Copyright © 2014 Elsevier Ltd. All rights reserved.

    After the derivation of weak conditions under which the potential for the Schroedinger operator is well defined the authers state an ergodicity assumption of this potential which ensures that the spectrum of this operator is a fixed non random set. Then random point interaction Hamiltonians are considered in this framework. Finally the authors consider a model where for sufficiently small fluctuations around the equilibrium positions a finite number of gaps appears. (HSI)

    The development of a completely new series of gas turbines requires significant capital, resources and know-how. MAN Diesel and Turbo strategically decided to create a small gas turbine in the 6 MW-class. The construction of the Gas Turbine has been on the basis of opportunities in current and future markets and the positioning of the competition, this has determined the characteristics and technical parameters which have been optimised in the 6 MW design. The construction uses extremely high precision engineering so that the assembly of sub-components to modules is a smooth flowing process and can guarantee the high standards both quality and performance which MAN Diesel and Turbo are operating to. The individual components must be tested and thoroughly validated many months before actual assembly of the first machine. These include in particular the compressor of the gas turbine and the combustion chamber. The combustion system required special attention, since the emissions are strongly focused to satisfy stringent environmental requirements. The planned tests are a prerequisite for the construction of such a prototype and must be successfully completed before the Gas Turbine will be accepted into service. (orig.)

    Full Text Available Warship Man-Machine-Environment System Engineering (MMESE is an integral part of the overall design, and its design principles were proposed according to safety, efficiency, comfort and pleasure. The typical characteristics of MMESE are summarized. The operating environment is extremely terrible on long voyages. High level collaboration is required due to the complex task system and large manpower demand. Owing to the dense computer interface information, the mental cognitive burden on the crew is heavy. The MMESE technology system is divided into four parts:man-machine coordinated, man-environment coordinated, the evaluation of man-machine-environment characteristics and the ergonomic simulation. Based on the MMESE development venation in this paper, the overseas and domestic research statuses are expounded. Interactive optimization can be realized according to the following aspects:researching the basic human characteristics of the crew, applying this to the warship's overall design, and formulating relevant ergonomic standards and norms. Next, Human System Integration (HSI professional engineering was introduced comprehensively into the marines in order to achieve an optimal system. On this basis, we completed the future development trend analysis. All these studies and results have some reference meaning for guiding the integrated optimization of warships as a whole, downsizing the manpower and improving efficiency.

    Full Text Available Abstract Background Identification of Anopheles gambiae s.s. and Anopheles arabiensis from field-collected Anopheles gambiae s.l. is often necessary in basic and applied research, and in operational control programmes. The currently accepted method involves use of standard polymerase chain reaction amplification of ribosomal DNA (rDNA from the 3' 28S to 5' intergenic spacer region of the genome, and visual confirmation of amplicons of predicted size on agarose gels, after electrophoresis. This report describes development and evaluation of an automated, quantitative PCR method based upon TaqMan™ single nucleotide polymorphism (SNP genotyping. Methods Standard PCR, and TaqMan SNP genotyping with newly designed primers and fluorophore-labeled probes hybridizing to sequences of complementary rDNA specific for either An. gambiae s.s. or An. arabiensis, were conducted in three experiments involving field-collected An. gambiae s.l. from western Kenya, and defined laboratory strains. DNA extraction was from a single leg, sonicated for five minutes in buffer in wells of 96-well PCR plates. Results TaqMan SNP genotyping showed a reaction success rate, sensitivity, and species specificity comparable to that of standard PCR. In an extensive field study, only 29 of 3,041 (0.95% were determined to be hybrids by TaqMan (i.e., having rDNA sequences from both species, however, all but one were An. arabiensis by standard PCR, suggesting an acceptably low (ca. 1% error rate for TaqMan genotyping in mistakenly identifying species hybrids. Conclusion TaqMan SNP genotyping proved to be a sensitive and rapid method for identification of An. gambiae s.l. and An. arabiensis, with a high success rate, specific results, and congruence with the standard PCR method.

  6. Biomedical support of man in space

    Pendergast, D. R.; Olszowka, A. J.; Rokitka, M. A.; Farhi, L. E.

    In its broadest sense, biomedical support of man in space must not be limited to assisting spacecraft crew during the mission; such support should also ensure that flight personnel be able to perform properly during landing and after leaving the craft. Man has developed mechanisms that allow him to cope with specific stresses in his normal habitat; there is indisputable evidence that, in some cases, the space environment, by relieving these stresses, has also allowed the adaptive mechanisms to lapse, causing serious problems after re-entry. Inflight biomedical support must therefore include means to simulate some of the normal stresses of the Earth environment. In the area of cardiovascular performance, we have come to rely heavily on complex feedback mechanisms to cope with two stresses, often combined: postural changes, which alter the body axis along which gravitational acceleration acts, and physical exercise, which increases the total load on the system. Unless the appropriate responses are reinforced continuously during flight, crew members may be incapacitated upon return. The first step in the support process must be a study of the way in which changes in g, even of short duration, affect these responses. In particular we should learn more about effects of g on the "on" and "off" dynamics, using a variety of approaches: increased acceleration on one hand at recumbency, immersion, lower body positive pressure, and other means of simulating some of the effects of low g, on the other. Once we understand this, we will have to determine the minimal exposure dose required to maintain the response mechanisms. Finally, we shall have to design stresses that simulate Earth environment and can be imposed in the space vehicle. Some of the information is already at hand; we know that several aspects of the response to exercise are affected by posture. Results from a current series of studies on the kinetics of tilt and on the dynamics of readjustment to exercise in

    The universe has always aroused people's curiosity. It fascinates and at the same time scares in its vastness. Encourages us to reflect of the meaning of human life. This begs the questions: whether there is a life beyond Earth? Whether is it possible that the man is alone in such a large space? These questions still remain unanswered, and topics concerning "the cosmos" constantly evoke many emotions. It is especially fascinating for the youngest students. Quite often, preschoolers can flawlessly name the planets according to their order of appearance in relation to the sun. They are happy to take the fun inspired by journeys into space. Teaching through action is extremely important for the development of the child-man* (Piaget, 2006). The thinking originates primarily from the action. Therefore, students should undertake independent research activities, perform experiments and conduct observations and thus raise questions about the world, looking for meanings and solutions. Adults (a teacher, a person with a passion) are to be the support in the search for knowledge, its processing and cleaning. Its role is to ensure a proper development of environment that is conducive to research activity. The answer to these requirements was to create in the oldest technical school in Poland (Railway Technical College, now Technical College No. 7) the astronomical observatory, which can be used by pupils of Warsaw's kindergartens and schools. There are organized activities for children and youth in this school, as well as trainings for teachers. Younger students during such an interdisciplinary courses are, among others, the opportunity to get acquainted with the construction of the telescope, they can build their own rockets and organize their racing or create your own star constellations. Older students as a result of observations and experiments may confirm or refute the hypothesis that the universe is within each of us. The classes are enriched using applications on

    1993-01-01

    The development of new technologies in recent years has led to a tremendous increase in the information to be mastered by operators in industrial processes. The information at operators disposal both in routine situations and accidental ones needs to be well prepared and organized to ensure reliability and safety. The man-machine interface should give operators all the necessary and clear indications on the process status and evolution so that the operators can operate the installation through adequate procedures. Procedures represent the real interface and mode of action of the operators on the machine, and they are of prime importance. Although they are by essence quite different, the routine, accident, and emergency procedures have in common one attribute: They all require a good safety culture both in their development and their implementation. From the definition given by the members of the International Nuclear Safety Advisory Group (INSAG), open-quotes Safety culture is that assembly of characteristics and attitudes in organizations and individuals which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance,close quotes one can see that two aspects are embedded, a collective attitude that in fact is reflected in the managerial framework and an individual one that is linked to personnel behavior and work practices

    In the last years the interest in process control has expecially focused on problems of man-machine communication. It depends on its great importance to process performance and user acceptance. Advanced computerized operator aids, e.g. in nuclear power plants, are as well as their man-machine interface. In the Central Institute for Nuclear Research in Rossendorf a computerized operator support system for nuclear power plants is designed, which is involved in a decentralized process automation system. A similar but simpler system, the Hierarchical Informational System (HIS) at the Rossendorf Research Reactor, works with a computer controlled man-machine interface, based on menu. In the special case of the disturbance analysis program SAAP-2, which is included in the HIS, the limits of menu techniques are obviously. Therefore it seems to be necessary and with extended hard- and software possible to realize an user controlled natural language interface using Artificial Intelligence (AI) methods. The draft of such a system is described. It should be able to learn during a teaching phase all phrases and their meanings. The system will work on the basis of a self-organizing, associative data structure. It is used to recognize a great amount of words which are used in language analysis. Error recognition and, if possible, correction is done by means of a distance function in the word set. Language analysis should be carried out with a simplified word class controlled functional analysis. With this interface it is supposed to get experience in intelligent man-machine communication to enhance operational safety in future. (author)

    2018-03-01

    Full Text Available Brain iron is tightly regulated by a multitude of proteins to ensure homeostasis. Iron dyshomeostasis has become a molecular signature associated with aging which is accompanied by progressive decline in cognitive processes. A common theme in neurodegenerative diseases where age is the major risk factor, iron dyshomeostasis coincides with neuroinflammation, abnormal protein aggregation, neurodegeneration, and neurobehavioral deficits. There is a great need to determine the mechanisms governing perturbations in iron metabolism, in particular to distinguish between physiological and pathological aging to generate fruitful therapeutic targets for neurodegenerative diseases. The aim of the present review is to focus on the age-related alterations in brain iron metabolism from a cellular and molecular biology perspective, alongside genetics, and neuroimaging aspects in man and rodent models, with respect to normal aging and neurodegeneration. In particular, the relationship between iron dyshomeostasis and neuroinflammation will be evaluated, as well as the effects of systemic iron overload on the brain. Based on the evidence discussed here, we suggest a synergistic use of iron-chelators and anti-inflammatories as putative anti-brain aging therapies to counteract pathological aging in neurodegenerative diseases.

    Transfer to man of transuranic element contamination may occur by the inhalation or ingestion pathways. The measurements of globally dispersed fall-out radioactivity have provided pertinent data on the environmental behaviour of plutonium. Additional data may eventually become available for americium. From the measured and inferred concentrations of fall-out plutonium, the inhalation intake has been determined and the ICRP Task Group lung model used to estimate deposition in the lung and transfer to other body organs. The computed body burden reached a maximum of 4pCi in 1964 and is currently about 2.5pCi. A complete diet sampling has been conducted to determine ingestion intake. Plutonium concentration in food ranged from 0.01pCi/kg in shellfish to undetected (less than 0.0003pCi/kg) in milk. Annual intake in total diet is estimated to have been 1.6pCi in 1972. Low uptake by the gastrointestinal tract makes contribution to organ burdens from ingestion negligible. Long-term pathway considerations include plant uptake from the cumulative deposit in soil and resuspension. Downward movement in soil may limit the significance of these long-term pathway components.

There is a great need to determine the mechanisms governing perturbations in iron metabolism, in particular to distinguish between physiological and pathological aging to generate fruitful therapeutic targets for neurodegenerative diseases. The aim of the present review is to focus on the age-related alterations in brain iron metabolism from a cellular and molecular biology perspective, alongside genetics, and neuroimaging aspects in man and rodent models, with respect to normal aging and neurodegeneration. In particular, the relationship between iron dyshomeostasis and neuroinflammation will be evaluated, as well as the effects of systemic iron overload on the brain. Based on the evidence discussed here, we suggest a synergistic use of iron-chelators and anti-inflammatories as putative anti-brain aging therapies to counteract pathological aging in neurodegenerative diseases.

    Full Text Available A software and control architecture for a humanoid robot is a complex and large project, which involves a team of developers/researchers to be coordinated and requires many hard design choices. If such project has to be done in a very limited time, i.e., less than 1 year, more constraints are added and concepts, such as modular design, code reusability, and API definition, need to be used as much as possible. In this work, we describe the software architecture developed for Walk-Man, a robot participant at the Darpa Robotics Challenge. The challenge required the robot to execute many different tasks, such as walking, driving a car, and manipulating objects. These tasks need to be solved by robotics specialists in their corresponding research field, such as humanoid walking, motion planning, or object manipulation. The proposed architecture was developed in 10 months, provided boilerplate code for most of the functionalities required to control a humanoid robot and allowed robotics researchers to produce their control modules for DRC tasks in a short time. Additional capabilities of the architecture include firmware and hardware management, mixing of different middlewares, unreliable network management, and operator control station GUI. All the source code related to the architecture and some control modules have been released as open source projects.

    The Exploration Laboratory Analysis (ELA) project supports the Exploration Medical Capability Element under the NASA Human Research Program. ELA instrumentation is identified as an essential capability for future exploration missions to diagnose and treat evidence-based medical conditions. However, mission architecture limits the medical equipment, consumables, and procedures that will be available to treat medical conditions during human exploration missions. Allocated resources such as mass, power, volume, and crew time must be used efficiently to optimize the delivery of in-flight medical care. Although commercial instruments can provide the blood and urine based measurements required for exploration missions, these commercial-off-the-shelf devices are prohibitive for deployment in the space environment. The objective of the ELA project is to close the technology gap of current minimally invasive laboratory capabilities and analytical measurements in a manner that the mission architecture constraints impose on exploration missions. Besides micro gravity and radiation tolerances, other principal issues that generally fail to meet NASA requirements include excessive mass, volume, power and consumables, and nominal reagent shelf-life. Though manned exploration missions will not occur for nearly a decade, NASA has already taken strides towards meeting the development of ELA medical diagnostics by developing mission requirements and concepts of operations that are coupled with strategic investments and partnerships towards meeting these challenges. This paper focuses on the remote environment, its challenges, biomedical diagnostics requirements and candidate technologies that may lead to successful blood-urine chemistry and biomolecular measurements in future space exploration missions.

    The ALICE collaboration has just lifted the dipole of the muon spectrometer and reassembled it on the other side of the huge solenoid magnet. This incredible feat involved lifting no fewer than 900 tonnes of equipment over the red octagonal yoke inherited from the L3 experiment at a height of 18 metres. A special lifting gantry weighing 5 tonnes had to be developed to move and install the coils. Huge clamps, which can be seen at the front, were used to rotate these enormous 32-tonne components. The whole assembly was raised to the cavern ceiling using an overhead travelling crane. With just 3 centimetres to spare below and 2 centimetres above, there was just enough room for the coil to pass. The operation required the overhead travelling crane to be operated with extreme precision. The coil was then placed on a 4.5-metre-high platform on the other side of the magnet.

    1980-01-01

    Evaluation of nuclear power plant incidents frequently reveals man as a major element of risk. Yet, in a nuclear power plant man has the function of an important protective barrier, either by maintaining the plant, by detecting and limiting faults or incidents, or by taking proper measures in accidents. This is true despite, or perhaps because of, the high degree of plant automation. For this reason, it is indispensable that a high level of engineered plant safeguards be accompanied by a minimum of faults contributed by human action. This implies that the staff and their working conditions must meet the same stringent safety requirements as the nuclear power plant proper. Reactor manufacturers, nuclear power plant operators and the responsible authorities try to optimize this human contribution. The Federal Ministry of the Interior, through its Special Technical Guidelines and its continuation training measures, occupies an important position in this respect. Further measures and ordinances are being prepared by that Ministry. (orig.) [de

    As automation and advanced technologies are introduced into transport systems ranging from the Next Generation Air Transportation System termed NextGen, to the advanced surface transportation systems as exemplified by the Intelligent Transportations Systems, to future systems designed for space exploration, there is an increased need to validly predict how the future systems will be vulnerable to error given the demands imposed by the assistive technologies. One formalized approach to study the impact of assistive technologies on the human operator in a safe and non-obtrusive manner is through the use of human performance models (HPMs). HPMs play an integral role when complex human-system designs are proposed, developed, and tested. One HPM tool termed the Man-machine Integration Design and Analysis System (MIDAS) is a NASA Ames Research Center HPM software tool that has been applied to predict human-system performance in various domains since 1986. MIDAS is a dynamic, integrated HPM and simulation environment that facilitates the design, visualization, and computational evaluation of complex man-machine system concepts in simulated operational environments. The paper will discuss a range of aviation specific applications including an approach used to model human error for NASA s Aviation Safety Program, and what-if analyses to evaluate flight deck technologies for NextGen operations. This chapter will culminate by raising two challenges for the field of predictive HPMs for complex human-system designs that evaluate assistive technologies: that of (1) model transparency and (2) model validation.

These occured either during the design and construction, the commissioning, the reconditioning or the operation of the plants. This very fact stresses human responsibility for the safety of nuclear power plants, in spite of those plants being automated to a high degree and devices. (orig.) [de

    Birth and development of the man-made gemstones in the 20th century are outlined. Manufacturing gemstones was initiated by the invention of corundum production, followed by production of rubies and sapphires. In 1950 GE Co. synthesized diamonds, after that, most gemstones were manufactured consequently by progress of technologies of single crystal growing and ceramic manufacturing. In the 21st century, steep growth in demand is not expected but it seems to keep steady growth and the importance and necessity of man-made gemstones may be increased because of global environmental issues. Man-made gemstones seem to have both personality and variety of characteristics. (NEDO)

    1990-08-01

    The importance of man-machine interface for ensuring safe and reliable operation of nuclear power plants has always been recognized. Since the early 1970's, the concepts of operator support and human factors have been increasingly used to better define the role of control rooms. In the late 1970's, the lessons learned from experience considerably accelerated the development of recommendations and regulatory requirements governing the resources and data available to operators in nuclear power plant control rooms, and specified the expertise required to assist them in case of need. This document summarizes the steps which have been taken and are being planned around the world to improve the man-machine interface for safe and economic power generation. It intends to present to the reader useful examples on some selected control room design and man-machine interface practices for operation and surveillance of nuclear power plants. 53 refs, 94 figs, 27 tabs

    This paper describes ongoing research at ORNL to develop a man/machine interface system that can be used to remotely control a system composed of a transporter base and a force-reflecting, servo-controlled manipulator. A unique feature of the concept is the incorporation of totally remote operation. Thus, a major objective is the requirement that an operator have a sense of presence in the remote environment. Man/machine interface requirements for this totally remote operation remain to be developed. Therefore, a simulator is being built to optimize such requirements and the developments are discussed

  7. Thoughts on the cultural evolution of man. Developmental imprinting and transgenerational effect.

    Csaba, György

    2007-01-01

    The biological evolution of man stopped since it has been conveyed to the objects, created by man. This paper introduces the concept of "conveyed evolution". Being part of the cultural evolution, the conveyed evolution is a continuation of the biological one. There are several similarities between the laws of biological and conveyed evolution, albeit the differences are important as well. Some laws of the conveyed evolution are described here. The conveyed evolution has man-made repair mechanisms (medicine, protection of environment) which defend man from harm. Man's fragility limits the progress of conveyed evolution. However, artificial compounds or environmental pollutants which are provoked by the conveyed evolution induce chemical (hormonal) imprinting in the developmental critical periods, which is transmitted to the progeny generations (transgenerational effect). This could cause evolutionary alterations without mutation.

  8. Hematologic syndrome in man modeled from mammalian lethality

    Jones, T.D.

    1981-01-01

    Data on acute radiation lethality due to failure of the hematologic system in rats, mice, dogs, swine, monkeys and man are analyzed. Based on the available data, the mortality incidences for 1-100% levels can be computed directly if one has only an estimate of the dose lethal to 50% of the population (LD 50 ) for the mammalian strain and radiation environment of interest. The sole restriction is that the dose profile to the marrow be moderately uniform. If an LD 50 for any exposure situation has been measured, then one can readily scale to any desired situation through implicit-biological and empirical-physical relationships. The LD 50 for man, exposed to an isotropic cloud of photons, and knowledge of the bone-marrow dose profiles readily permit evaluation of the model for other levels of human mortality from different irradiating particles, partial body irradiation and spatially dependent and/or mixed radiation environments.

    Superfluid helium is increasingly used as a coolant for superconducting devices in particle accelerators: the lower temperature enhances the performance of superconductors in high-field magnets and reduces BCS losses in RF acceleration cavities, while the excellent transport properties of superfluid helium can be put to work in efficient distributed cooling systems. The thermodynamic penalty of operating at lower temperature however requires careful management of the heat loads, achieved inter alia through proper design and construction of the cryostats. A recurrent question appears to be that of the need and practical feasibility of an additional screen cooled by normal helium at around 4.5 K surrounding the cold mass at about 2 K, in such cryostats equipped with a standard 80 K screen. We introduce the issue in terms of first principles applied to the configuration of the cryostats, discuss technical constraints and economical limitations, and illustrate the argumentation with examples taken from large proj...

    The first major man-made environmental problem was the soil acidification, caused primarily by the massive industrial emissions of sulphur dioxide. Then came the problem of ozone depletion, caused by the emissions of man-made halocarbons. More recently, the possibility of man-made climate change has received a lot of attention. These three man-made problems are interconnected in fundamental ways and require for their solution interdisciplinary and international approach. Narrowing of the scientific uncertainties connected with the problems mentioned above can be expected through international `Global Change` programmes such as the World Climate Research Programme (WCRP) and the International Geosphere-Biosphere Programme (IGBP). Periodic assessments of the type produced by the IPCC will clearly be needed. Also in the future such assessments should form the scientific basis for international negotiations and conventions on the climate change issue

    Chamberlain, N.

    1989-01-01

    'Nuclear Fuel ' The Thinking Man's Alternative' is the title of the 55th Melchett Lecture given by Neville Chamberlain, Chief Executive of British Nuclear Fuels plc. This article is based on the address, the essence of which is that the case for nuclear power should be based upon an appreciation of the totality and sophistication of man's handling of his energy needs - not on a glib catch-phase or on a simple political dogma or on an economic argument. Arguments in favour of nuclear power were discussed. The conclusion was that nuclear energy is the thinking man's alternative because only thinking man could have and can develop it; secondly, only thinking men should be authorized to exploit and control it; thirdly, a thinking person will appreciate that, properly thought out and controlled, it must be the most important source of future energy for the benefit of mankind.

    The historical development of plant instrumentation and control system accompanying the introduction of automation is shown by the example of nuclear power plants. It is explained, and the change in the role of operators in the man-machine system is mentioned. Human errors are the serious problem in various fields, and automation resolves it. But complex systems also caused various disasters due to the relation of men and machines. The problem of human factors in high risk system automation is considered as the heightening of reliability and the reduction of burden on workers by decreasing human participation, and the increase of the risk of large accidents due to the lowering of reliability of human elements and the strengthening of the training of workers. Human model and the framework of human error analysis, the development of the system for man-machine system design and information analysis and evaluation, the significance of physiological index measurement and the perspective of the application, the analysis of the behavior of subjects in the abnormality diagnosis experiment using a plant simulator, and the development to the research on mutual adaptation interface are discussed. In this paper, the problem of human factors in system safety, that technical advancement brings about is examined, and the basic research on the advancement of man-machine systems by the author is reported.

    Full Text Available Background: The treatment of pressure sores represents a significant challenge to health care professionals. Although, pressure wound management demands a multidisciplinary approach, soft tissue defects requiring reconstruction are often considered for surgical management. Myocutaneous and fasciocutaneous flaps can provide stable coverage of pressure sores. Purpose: Here, we describe our experience using a recent fasciocutaneous flap, which is named ′reading man′ flap, in sacral, ischial, and trochanteric pressure sores. Materials and Methods: During a period of 1 year the authors operated 16 patients, 11 men, and 5 women, using the reading man flap. The ages of the patients ranged from 24 to 78 years. The location of pressure sores was 8 sacral, 5 ischial, and 3 trochanteric pressure sores. The mean size of pressure sores was 8 cm × 9 cm. Results: All pressure sores covered bt the Reading Man flap healed asymptomatically. After follow-up of 2-8 months, no recurrences were encountered and no further surgical intervention was required. Conclusion: The reading man flap was found to be a useful technique for the closure of pressure sore in different anatomic locations. The advantage of tension-free closure and the minimal additional healthy skin excision made this flap a useful tool in pressure sore reconstructions.

    2013-07-01

    Full Text Available OBJECTIVES: This pilot study was designed to utilize stroke volume variation and cardiac index to ensure fluid optimization during one-lung ventilation in patients undergoing thoracoscopic lobectomies. METHODS: Eighty patients undergoing thoracoscopic lobectomy were randomized into either a goal-directed therapy group or a control group. In the goal-directed therapy group, the stroke volume variation was controlled at 10%±1%, and the cardiac index was controlled at a minimum of 2.5 L.min-1.m-2. In the control group, the MAP was maintained at between 65 mm Hg and 90 mm Hg, heart rate was maintained at between 60 BPM and 100 BPM, and urinary output was greater than 0.5 mL/kg-1/h-1. The hemodynamic variables, arterial blood gas analyses, total administered fluid volume and side effects were recorded. RESULTS: The PaO2/FiO2-ratio before the end of one-lung ventilation in the goal-directed therapy group was significantly higher than that of the control group, but there were no differences between the goal-directed therapy group and the control group for the PaO2/FiO2-ratio or other arterial blood gas analysis indices prior to anesthesia. The extubation time was significantly earlier in the goal-directed therapy group, but there was no difference in the length of hospital stay. Patients in the control group had greater urine volumes, and they were given greater colloid and overall fluid volumes. Nausea and vomiting were significantly reduced in the goal-directed therapy group. CONCLUSION: The results of this study demonstrated that an optimization protocol, based on stroke volume variation and cardiac index obtained with a FloTrac/Vigileo device, increased the PaO2/FiO2-ratio and reduced the overall fluid volume, intubation time and postoperative complications (nausea and vomiting in thoracic surgery patients requiring one-lung ventilation.

    2017-09-01

    Full Text Available The film recreates Shakespeare’s masterly play set to music 280 years later by Guiuseppe Verdi after an adaptation for the musical theatre by Arrigo Boito. Otello forms the “third way” of Verdi in which the sung word reaches a summit in doing justice to the written text, anticipating what would later be refined by “verism”. The struggle between the falsified infidelity and the amorous sentiments of the Moor of Venice provide elements that are summarised in eloquent lyricism and profound musical emotion. Zeffirelli’s Otello is a lofty concatenation of talents that affords the poetic essence and drama of the story a focused significance. Melodic nobility, singing, scenery, complemented by a constant flow of ideas, nuances, effects and hues are all there.

  13. One man's poison is another man's meat: using azithromycin-induced phospholipidosis to promote ocular surface health.

    2014-06-05

    Drug-induced phospholipidosis (PLD) is a common adverse effect which has led to the termination of clinical trials for many candidate pharmaceuticals. However, this lipid-inducing effect may be beneficial in the treatment of meibomian gland dysfunction (MGD). MGD is the major cause of dry eye disease (DED), which affects 40 million people in the USA and has no cure. Azithromycin (AZM) is a PLD-inducing antibiotic that is used off-label to treat MGD, and is presumably effective because it suppresses the MGD-associated conjunctival inflammation (i.e. posterior blepharitis) and growth of lid bacteria. We hypothesize that AZM can act directly to promote the function of human meibomian gland epithelial cells by inducing PLD in these cells, characterized by the accumulation of lipids and lysosomes. Immortalized human meibomian gland epithelial cells (HMGEC) were cultured with or without azithromycin for 5 days. Cells were evaluated for cholesterol (Filipin) and neutral lipid (LipidTox) staining, as well as the appearance of lysosomes (LysoTracker) and lamellar bodies (transmission electron microscopy, TEM). The lipid composition of cellular lysates was analyzed by high performance thin-layer chromatography. Our findings demonstrate that AZM stimulates the accumulation of free cholesterol, neutral lipids and lysosomes in HMGEC. This AZM-induced increase of neutral lipid content occurred predominantly within lysosomes. Many of these vesicles appeared to be lamellar bodies by TEM, which is the characteristic of PLD. Our findings also show that AZM promotes an accumulation of free and esterified cholesterol, as well as phospholipids in HMGECimmortalized. Our results support our hypothesis and confirm the beneficial effect of PLD induced by AZM on HMGEC. Our discovery reveals a new potential use of PLD-inducing drugs, and makes this adverse effect a beneficial effect. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Singer, S. F.

    The rationale for a manned mission to the satellites of Mars is discussed. The view has been expressed that NASA must define a major program to follow the Shuttle and to utilize it. However, such a program could not be initiated and proceed without public support, and to obtain this support, public interest would have to be excited. It is shown that, of a number of possible targets for manned exploration in the solar system, Mars appears to be the only possible candidate. Attention is given to a comparison of three Mars missions, a Mars 1984 mission, a manned landing on Mars surface, a manned landing on Phobos and Deimos (Ph-D project), putting men in Mars orbit, the capabilities of the Ph-D mission, a description of the spacecraft, a Ph-D project operations plan, and aspects of timing, technology, and costs.

  15. Some consideration of Japanese standard man value

    Yoshizawa, Yasuo; Kusama, Tomoko

    1976-01-01

    Numerical values of standard man or reference man is important problem in the field of radiation protection and safety. The standard man values given by ICRP were obtained from European and North American adult data. For that reason, there are some theoretical problems in the application of standard man values to Japanese. The purpose of the present paper is to consider the difference of values between Japanese and standard man. The standard man values are divided into three categories. The first category is the size and weight of the body or organ, the second is the values of elementary composition, and the third is the numerical factors related to metabolic kinetics. It is natural that some values of the second and the third categories have little difference between Japanese and European. On the other hand, there are some differences in the value of the first category, but the differences can calculation in proportional allotment to the body weight. The values concerning the thyroid gland and iodine metabolism are important for radiation protection. It has been foreseen that these values of Japanese are significantly different from standard man. A survey of past reports was carried out with a view to search for normal values of the weight, iodine content, and iodine uptake rate of the thyroid of Japanese. The result of the survey showed that the weight of thyroid are about 19g for adult male and 17g for adult female and that the iodine contents are 12-22mg and iodine uptake rate (fw) is about 0.2.

  16. Conceptual models in man-machine design verification

    International Nuclear Information System (INIS)

    Rasmussen, J.

    1985-01-01

    The need for systematic methods for evaluation of design concepts for new man-machine systems has been rapidly increasing in consequence of the introduction of modern information technology. Direct empirical methods are difficult to apply when functions during rare conditions and support of operator decisions during emergencies are to be evaluated. In this paper, the problems of analytical evaluations based on conceptual models of the man-machine interaction are discussed, and the relations to system design and analytical risk assessment are considered. Finally, a conceptual framework for analytical evaluation is proposed, including several domains of description: 1. The problem space, in the form of a means-end hierarchy; 2. The structure of the decision process; 3. The mental strategies and heuristics used by operators; 4. The levels of cognitive control and the mechanisms related to human errors. Finally, the need for models representing operators' subjective criteria for choosing among available mental strategies and for accepting advice from intelligent interfaces is discussed

    1986-01-01

    The automation, robotics, and inflight training requirements of manned Mars missions will be supported by similar capabilities developed for the space station program. Evolutionary space station onboard training facilities will allow the crewmembers to minimize the amount of training received on the ground by providing extensive onboard access to system and experiment malfunction procedures, maintenance procedures, repair procedures, and associated video sequences. Considerable on-the-job training will also be conducted for space station management, mobile remote manipulator operations, proximity operations with the Orbital Maneuvering Vehicle (and later the Orbit Transfer Vehicle), and telerobotics and mobile robots. A similar approach could be used for manned Mars mission training with significant additions such as high fidelity image generation and simulation systems such as holographic projection systems for Mars landing, ascent, and rendezvous training. In addition, a substantial increase in the use of automation and robotics for hazardous and tedious tasks would be expected for Mars mission. Mobile robots may be used to assist in the assembly, test and checkout of the Mars spacecraft, in the handling of nuclear components and hazardous chemical propellent transfer operations, in major spacecraft repair tasks which might be needed (repair of a micrometeroid penetration, for example), in the construction of a Mars base, and for routine maintenance of the base when unmanned.

    Compes, P.C.; Wolff, H.A.

    1980-01-01

    Safety engineering derives its justification from the success achieved in maintaining and enlarging safety, more precisely, from activities aimed at avoiding or preventing damage caused by accidents. Man is not only affected by accidents but is also the cause of accidents, either directly or indirectly, and thus is to be regarded as the actual cause or preventer of accidents. The Second International Summer Symposium of the Society for Safety Engineering (GfS) which was held at Duesseldorf in 1980 brought into focus this aspect and the importance to be attached to the individual man and the whole mankind in the field of accident prevention. 'Man as a safety problem in technical systems' - a great and weighty field of problems, the large extent of which and the complex content of which was to be discussed by the programme with its many different contributions, on the one hand by presenting an outline as completely as possible, and on the other hand by finding further-reaching solutions for at least some problems. This was the purpose of the dialogues held between theory and practice on the one hand, and between safety engineering and, in this case, the human sciences on the other hand. (orig./RW) [de

    Recent development of artificial intelligence(AI) seems to offer new possibility to strengthen the performance of the operator support system. From this point of view, a national project of Advanced Man-Machine System Development for Nuclear Power Plant (MMS-NPP) has been carried out since 1984 as 8-year project. This project aims at establishing advanced operator support functions which support operators in their knowledge-based behaviors and smoother interface with the system. This paper describes the role of MMS-NPP, the support functions and the main feature of the MMS-NPP detailed design with its focus placed on the realization methods using AI technology of the support functions for BWR and PWR plants.

    Moghissi, A.A.; Carter, M.W.

    1976-01-01

    The Atomic Energy Act of 1954 and its subsequent amdenments separate radioactive materials and ionizing radiation into two categories. The one category, man-made, which is covered by that Act has received considerable care and attention and thus causes a small population exposure and dose. However, the second category, natural, has received very little care and attention and, in many cases, has been neglected. Ironically, natural radiation causes the major fraction of the population exposure. This paper describes the exposure from these categories, identifies laws covering each category, and attempts a risk-benefit analysis of the subject. It also discusses the difficulties associated with differentiating between natural and man-made radiation

    The Space Station Freedom program is developing an operations planning structure which assigns responsibility for planning activities to three tiers of management. The strategic level develops the policy, goals and requirements for the program over a five-year horizon. Planning at the tactical level emphasizes program integration and planning for a two-year horizon. The tactical planning process, architecture, and products have been documented and discussed with the international partners. Tactical planning includes the assignment of user and system hardware as well as significant operational events to a time increment (the period of time from the arrival of one Shuttle to the manned base to the arrival of the next). Execution-level planning emphasizes implementation, and each organization produces detailed plans, by increment, that are specific to its function.

    IN 1992 Huang Wentao, 22, set a world record in the disabled long jump. Before he set this record, his parents had never thought of letting him do sports. He is the second son of Liu Linzhi. When Liu got pregnant again, she felt happy and at ease. She wanted to have a beautiful girl because she thought she would then be satisfied, having one son and one daughter. Of course it would also be all right if she had a second son like her first child. The two brothers could take care of each other and be friends. The child, a good-looking boy, came into the world safely. Like most babies, newborn Huang sometimes cried, sometimes opened his big eyes and

    2014-07-01

    At Sandia National Laboratories in New Mexico (SNL/NM), the design, construction, operation, and maintenance of facilities is guided by industry standards, a graded approach, and the systematic analysis of life cycle benefits received for costs incurred. The design of the physical plant must ensure that the facilities are "fit for use," and provide conditions that effectively, efficiently, and safely support current and future mission needs. In addition, SNL/NM applies sustainable design principles, using an integrated whole-building design approach, from site planning to facility design, construction, and operation to ensure building resource efficiency and the health and productivity of occupants. The safety and health of the workforce and the public, any possible effects on the environment, and compliance with building codes take precedence over project issues, such as performance, cost, and schedule. These design standards generally apply to all disciplines on all SNL/NM projects. Architectural and engineering design must be both functional and cost-effective. Facility design must be tailored to fit its intended function, while emphasizing low-maintenance, energy-efficient, and energy-conscious design. Design facilities that can be maintained easily, with readily accessible equipment areas, low maintenance, and quality systems. To promote an orderly and efficient appearance, architectural features of new facilities must complement and enhance the existing architecture at the site. As an Architectural and Engineering (A/E) professional, you must advise the Project Manager when this approach is prohibitively expensive. You are encouraged to use professional judgment and ingenuity to produce a coordinated interdisciplinary design that is cost-effective, easily contractible or buildable, high-performing, aesthetically pleasing, and compliant with applicable building codes.

    It is well known, that the president of the first Moldavian Parliament in 1918 was Ion Inculetz (borne on 5 april, 1884, Rezeni vill., Lapusna county, Basarabia - died on 19 november 1940, Bucharest, regraved in Barnova, near Iasi). On 24 January 1918 this Parliament claimed the independence of Basarabia from the Russia (The Democratic Republic of Moldova). On 27 march of the same year in a solennele session the Parliament claimed "The Democratic Republic of Moldova (Basarabia) in its borders between Prut, Dniester rivers, Black Sea, and old borders with Austria, rupted by Russia more than one hundred years from the body of old Moldova, due to the historical right and due to the right of the selfdetermination of peoples, is unifying forever with She's mother Romania ". After the Unification Ion Inculetz activated as representative of Basarabia in the Romanian Parliament. He was a man of democratic views, a partisan of social-democracy in Russia, as well as in Romania after the unification. The progress of peoples was one of His main political goals. It is less known, however, that Inculetz was a remarkable physicist. This is the subject of the conference. After the finish of the secondary studies in Chisinau, He entered to Jur'ev (actually Tartu- Estonia) University Medecine Department, but after one year of studies He moved to Sankt-Petersburg Imperial University, where He specialized in physics and mathematics. After the finish of the Physical Mathematical Department he became private-docent (Associate Professor). Concomittantly He taught methematics at one of the comercial schhols in Sankt Petersburg. In the same time he was a Scientific Secretary of the journal "Nauchnoie Obozrenie" ("Scientific Review") and a researcher at the Meteorological Observatory in Sankt-Petersburg (since 1914). Since 1912 till 1917 He published a series of papers in the fields of physics and meteorology, particularly concerned to anodic rays, Krooks tubes, radiactivity, Doppler effect

    1993-01-01

    The Royal Swedish Academy of Engineering Sciences has set up a committee known as The Committee of Man, Technology and Society. The members of this committee form an interdisciplinary group for the study of the interaction between scientific and technological advances and the way in which society evolves. Most of the committees activities have focused on the present relationship between man, technology and society. Attempts have been made to assess the future influence on society of key developments in biotechnology, electronic communication and systems analysis. In order to pursue this path still further, the committee decided to arrange an international symposium on the topic Man and Technology in the Future at the village of Forsmark on the Baltic coast of Sweden. The proceedings consists of 13 lectures centered on energy systems - and the connected waste problems, biotechnology, and telecommunications. Separate abstracts were prepared for 5 of the lectures in this volume

    No suitable data are available from man for the quantitative assessment of genetic radiation risk. Therefore, the results from experiments on animals must be utilized. Two hypotheses are presented here in drawing analogical conclusions from one species to another. Although the extrapolation of results from animal experiments remains an open question, the use of experimental results from mice seems to be justified for an assessment of the genetic radiation risk in man.

    The U.S. Department of Energy Strategic Petroleum Reserve stores crude oil in caverns solution-mined in salt domes along the Gulf Coast of Louisiana and Texas. The CaveMan software program has been used since the late 1990s as one tool to analyze pressure mea- surements monitored at each cavern. The purpose of this monitoring is to catch potential cavern integrity issues as soon as possible. The CaveMan software was written in Microsoft Visual Basic, and embedded in a Microsoft Excel workbook; this method of running the CaveMan software is no longer sustainable. As such, a new version called CaveMan Enter- prise has been developed. CaveMan Enterprise version 1.0 does not have any changes to the CaveMan numerical models. CaveMan Enterprise represents, instead, a change from desktop-managed work- books to an enterprise framework, moving data management into coordinated databases and porting the numerical modeling codes into the Python programming language. This document provides a report of the code validation and verification testing.

    An immunocompromised man presented with an inflammatory eyelid lesion. Biopsy was performed; histopathology and special staining confirmed a diagnosis of bacillary angiomatosis. The man was treated with oral erythromycin, and the lesion resolved. The etiologic agents of bacillary angiomatosis are Bartonella henselae and Bartonella quintana, Gram-negative coccobacilli. The organisms stain positively with the Warthin-Starry silver stain. Lesions can be cutaneous or visceral and have been commonly described in immunocompromised patients. Histopathologic examination of lesions reveals angiogenesis and cellular proliferation. Bacillary angiomatosis can be treated with oral antibiotics.

  19. Why Cannot Today’s Medicine Tolerate Man?

    Directory of Open Access Journals (Sweden)

    Farzad Goli

    Full Text Available Today, anyone who has travelled a little through history or reflected on social systems knows that although social systems are established and designed to satisfy our needs and demands, they have needs of their own which guarantee their life and may precede our needs. Hence, these systems, which were supposed to serve us indisputably like the genie, make us serve them in different ways. Medicine is one of such social systems which were undoubtedly established to satisfy our vital need to care and cure. To exist and develop, medicine needs to know and control personal and social conditions, and to actualize this need, it needs knowledge, money, and, perhaps prior to all of these, it needs to be trusted. To know man, he should be completely uncovered, observable, and dissected into his parts and the relationship between his parts should be explained in simple models. And to direct the condition toward maximum health, men should be converted into statistical entities and their individual differences, conditions, and narratives have to be ignored so that they become predictable and, consequently, controllable creatures. The story of relative, and almost necessary, conflict between man and medicine is as simple as it is explained. Before we go any further into the discussion, we should remember that a real man, with his whole phenomenological world and new-emergent and unique properties of autonomy and consciousness, may suddenly behave like a joker and disturb all the rules of medicine's play. It is natural that such subtleties cannot be tolerated by a materialistic model which is relying on knowledge of mechanistic organization of parts. The aim of this theoretical essay was to increase the readers’ awareness of biomedical model restrictions and organized cruelties it imposes on man in practice and theory. The discussion of alternate models which we are turning to recently has been undertaken in other essays.

    1983-10-01

    We are presently participating in a program to optimize the functional man-machine interface for Liquid Metal-Cooled Fast Breeder Reactors. The overall objective of this program is to enhance operational safety; that is, to accommodate plant incidents through optimal integration of man and machine in performing the functions required to safely control a plant during both normal and off-normal conditions. Purpose of this talk is to describe an approach to determine the optimal roles of man and computer in the control of nuclear power plants. Purpose of this session was to get together people that are working in the areas of understanding of how operators control plants, and working on developing new aids for these operators. We were asked to explain how our modeling and approach we're taking will lead us to an optimization of the roles of the man and the computer in the control of nuclear power plants. Our emphasis was to be on the functions required for plant control, and how the attributes of the human operator and the attributes of the computer can be optimally used to enhance operational safety in performing these functions

    Science.gov (United States)

    1975-01-01

    Solid polymer electrolyte technology used in a water electrolysis system (WES) to generate oxygen and hydrogen for manned space station applications was investigated. A four-man rated, low pressure breadboard water electrolysis system with the necessary instrumentation and controls was fabricated and tested. A six man rated, high pressure, high temperature, advanced preprototype WES was developed. This configuration included the design and development of an advanced water electrolysis module, capable of operation at 400 psig and 200 F, and a dynamic phase separator/pump in place of a passive phase separator design. Evaluation of this system demonstrated the goal of safe, unattended automated operation at high pressure and high temperature with an accumulated gas generation time of over 1000 hours.

  2. Leak suppression at steam generator man-, hand-, and eyeholes

    International Nuclear Information System (INIS)

    Sylvain, C.; Sutz, P.; Gemma, A.

    1988-01-01

    Plant unavailability associated with primary and secondary holes is approximately the same as that caused by steam generator tube defects, i.e., 0.5%. Problems encountered with steam generator man-, hand-, and eyeholes during plant operation have led Electricite de France (EdF) and Framatome to improve hole seal design and to develop robots for closing and cleaning them. The data base available in France in this field on some 150 steam generators in 900- and 1300-MW(electric) pressurized water reactors (the equivalent of 300 reactor-yr of operation) has been the base of the developments described in this paper. Incidents occurring in operation primarily concern had-and inspection holes located on the steam generator's secondary side. They include four kinds: (1) leakage detected in operation, requiring forced outages, (2) leakage detected during plant restart after a scheduled shutdown and resulting in a restart delay, (3) pitting of seal mating surfaces, not inducing any leakage but jeopardizing subsequent compliance and requiring difficult and costly repairs, and (4) seizing of screws or bolts. New primary and secondary hole stud tightening and maintenance machines help to improve the efficiency of the in-service closing operations. They provide savings of up to 80% on labor, duration of operations, and exposure

    Argonne National Laboratory is constructing a 7-GeV Advanced Photon Source for use as a synchrotron radiation source in basic and applied research. The controls and computing environment for this accelerator complex includes graphical operator interfaces to the machine based on Motif, X11, and PHIGS/PEX. Construction and operation of the control system for this accelerator relies upon interactive interface builder and diagram/editor type tools, as well as a run-time environment for the constructed displays which communicate with the physical machine via network connections. This paper discusses our experience with several commercial CUI builders, the inadequacies found in these, motivation for the development of an application- specific builder, and design and implementation strategies employed in the development of our own Man-Machine Interface builder. 5 refs

Kratom is currently easily available worldwide via special shops and the Internet to use as a drug of abuse, opioid alternative, or pain killer. So far, the pharmacokinetics of this plant has been studied only in animals, and there is no such study in humans. The major abundant active alkaloid in Kratom, mitragynine, is one of the promising new chemical substances to be developed as a new drug. The aim of this study was to examine the pharmacokinetics of mitragynine and assess the linearity in pharmacokinetics in chronic users.Methods: Since Kratom is illegal in Thailand, studies in healthy subjects would be unethical. We therefore conducted a prospective study by enrolling ten chronic, regular, healthy users. We adjusted the steady state in each subject by giving a known amount of Kratom tea for 7 days before commencement of the experiment. We admitted and gave different oral doses to subjects to confirm linearity in pharmacokinetics. The mitragynine blood concentrations at 17 times points and the urine concentrations during the 24-hour period were collected and measured by liquid chromatography-tandem mass spectrometry method. Results: Ten male subjects completed

    2007-01-01

    Albert Schweitzer, the great missionary physician from the XXth century, had a versatile personality that integrated multiple talents, leading to the slightly frequent conjunction of the thinker with the man of action, and the humanist with the scientist and the artist. He studied all these disciplines in a brilliant manner: Philosophy, Theology, Music and Medicine; he was also a great scholar of Bach's work, Jesus Christ and the civilization history. In his maturity, this great man renounced to the fame and glory gained as intellectual and musician, to dedicate his life as a physician for the forgotten African natives. His deeply religious spirit allowed him to penetrate into the most recondite of the human soul; in his personality, he expressed in its entire dimension the eternally unsatisfied desire of the solitary man, against the immensity of the universe. His philosophy, based on the respect for life, was realized throughout the practice of the medical profession. His noble character and personality was based on the man as symbol, since it was not so much what he did helping people but what people could do to others due to him. His singular example represented a moral force in the world, superior to millions of men armed for a war. In 1953, he received the Nobel Peace Prize for his philanthropic work in Africa during more that fifty years, and for his deep love to the living beings. He was transformed in a perennial legend as the Lambaréné doctor.

    In training, it has been important to show good performance of operators dealing with abnormal operating; condition simulated by a training simulator. Video-taping of the scenario-based performance by instructors of a training center is the most common way. However, it is difficult for the experienced instructors to show good performance due to the stress of being video-taped. Therefore, the authors developed a system named Operator Behavior Computer Graphic System (OBCGS) to computer-graphically show the behavior of operators. The input data of this system are data on operation, watching, walking and utterances with time, objects of operation and watching, contents of their behavior, etc. The system temporally uses the output data of Man Machine Simulator developed by CRIEPI. OBCGS has 3 kinds of user interfaces. The first one computer-graphically shows 3 operators and one shift supervisor behaving in the control room from a bird's eye viewpoint. The second one has multi windows to show details of computer graphics of operators and control panels. The last one shows the history of operations, warnings and utterance. The system shows reasonable computer graphics in quality from the viewpoint of showing good performance of operations. This report also describes how to use the OBCGS and ways of application to the operator training. (author)

It has been recognized for quite some time that in large and complex man-machine interactive systems human errors can contribute substantially to failures of these systems, and that the improvement in the human interface in man-machine systems is essential for the safety of the plant. Many important surveys have been made in some member countries. These studies and operational experience have shown that it is possible to substantially reduce this adverse impact of human errors in nuclear power plant operations by the application of human factors technology. This technology. This technology includes: (1) selection of people with the requisite skills and knowledge and providing them with job-relevant training, (2) maintenance of the necessary job qualifications for each person in the plant, (3) design of man-machine interfaces which are fully compatible with the capabilities and limitations of the people in the system, and (4) design of job operations, including written materials, to facilitate required quality of human performance. A review is made of education/training, operator support systems, human error data collection, analysis of safety significant events and future activities. (Nogami, K.)

    The use of operant procedures was extended to decrease immediate echolalia and increase appropriate responding to questions of a 21-year-old autistic man. Multiple baseline designs demonstrated that echolalia was rapidly replaced with correct stimulus-specific responses. A variety of generalized improvements were observed in verbal responses to…

    Two significant psychological contributions for reducing risk in human behavior while operating with technical systems are presented. The ergonomic designing and the diagnostic selection method are explicated. Both hold a good tradition in this field and are successful in improving safety conditions for the so-called human factor in the man-machine-environment-relationship. (DG)

    Many European companies use some type of control-enhancing mechanism, such as dual class shares or a pyramid ownership structure. Such mechanisms cause deviations from the one share–one vote principle, allocating more voting rights than cash flow rights to some shares and, in turn, providing...

  13. Exploitation of new information technologies to improve the man-machine interface in particular in nuclear power plants control rooms (SR 2039/7)

    The establishment of a uniform computer-based user surface requires a qualification of the employed hard- and software which meets safety demands. This problem is outlined, pointing out those parts of safety instrumentation and control which for the time being have to be conventional in order to ensure sufficient safety precaution. Ergonomic problems of man-machine interaction, which have to be assessed when licensing computerized control rooms or mixed ones, are worked out and a way of solving them is shown. In this regard, observational and operational tasks are considered; activities, however, which are related to the modification of computer software remain unconsidered. (orig./DG) [de

  14. A new workstation based man/machine interface system for the JT-60 Upgrade

    Development of a new man/machine interface system was stimulated by the requirements of making the JT-60 operator interface more 'friendly' on the basis of the past five-year operational experience. Eleven Sun/3 workstations and their supervisory mini-computer HIDIC V90/45 are connected through the standard network; Ethernet. The network is also connected to the existing 'ZENKEI' mini-computer system through the shared memory on the HIDIC V90/45 mini-computer. Improved software, such as automatic setting of the discharge conditions, consistency check among the related parameters and easy operation for discharge result data display, offered the 'user-friendly' environments. This new man/machine interface system leads to the efficient operation of the JT-60. (author)

    This paper gives an overview of the current state of the art in man machine systems interaction studies, focusing on the problems derived from highly automated working environments and the role of humans in the control loop. In particular, it is argued that there is a need for sound approaches to design and analysis of Man-Machine Interaction (MMI), which stem from the contribution of three expertises in interfacing domains, namely engineering, computer science and psychology: engineering for understanding and modelling plants and their material and energy conservation principles; psychology for understanding and modelling humans and their cognitive behaviours; computer science for converting models in sound simulations running in appropriate computer architectures.

  16. The Somerton man : an unsolved history

    Directory of Open Access Journals (Sweden)

    Balint, Ruth

    2010-01-01

    Full Text Available The case of the unknown man who died mysteriously at Somerton Beach in South Australia in 1948 remains an open police investigation, although the trail today has grown fairly cold. Revisiting the case, and the responses the mystery of his person have elicited, enables a special historical insight into Australia’s postwar society, and the ways in which the past is continually reshaped by the subjectivities of the present. Further, an unsolved case such as this provides for a unique kind of historical project. The limitations of a history without a coherent centre are myriad, yet so are the possibilities. In this article, I explore the possibilities of an ‘unsolved history’, a history of dead ends, and argue that it is the very unknowable-ness of the Somerton Man that allows for a perception of history as multi-dimensional and complex.

  19. [Man's place and anthropology in bioethics].

    2013-01-01

    From the analysis of its epistemological status, the article focuses on the philosophical fundament of bioethics, stressing the need for an authentic anthropology as a reference or starting point. Being an applied ethics, the first fundament of bioethics is in ethics. It shows how only personalistic ethics, which takes as reference the nature or essence of man, can offer objective and universal criteria. Philosophical anthropology studies man as a whole, in an integral manner, from the perspective of its nature or fundamental aspects of his being. It analyzes the distinction and relationship between the philosophical anthropology and the positive anthropologies, as well as with the physical, human and social sciences. Finally, it reflects on the current anthropological crisis and its ethical consequences.

  20. Man-midwifery history: 1730-1930.

    Science.gov (United States)

    Shelton, D C

    2012-11-01

    This paper seeks to determine whether the man-midwives William Smellie and William Hunter deserve continuing approbation as 'Founding Fathers' of the obstetrics profession. Scrutiny of their careers reveals their involvement in murders for dissection. In addition, the man-midwifery initiative of delivery in lying-in hospitals resulted in around 1 million more deaths in Britain and Ireland between 1730 and 1930, than would have occurred had home-births remained as the norm. While some may still credit Smellie and Hunter with obstetric discoveries, their knowledge was obtained by murder-for-dissection. That indictment, together with the lying-in hospital legacy, far outweighs their discoveries. The paper invites further constructive discussion and debate, but concludes the accolade of Founding Fathers is undeserved. Any continuing endorsement of Smellie and Hunter effectively demeans the high ethical standards and reputation of current obstetric professionals.
