  3. One hundred years on..

    International Nuclear Information System (INIS)

    2014-01-01

    One hundred years on from the 'war to end all wars', the face of war has profoundly changed. Inter-State conflicts still exist, but are spatially limited; world war is no longer on the agenda. And if a major power is involved, conflict now has every chance of being both violent (given modern strike capabilities) and short (given the cost of strikes). At least three factors explain this shift, starting with the de-legitimising of war. The horrors of the world wars; a European edifice built on a rejection of war; a neo-pacifism born, in Europe, of wealth, ageing, and economic crisis; and finally, the delusions of the past twenty years, resulting from commitments 'that do not amount to war': all downgrade the war hypothesis. The second factor is the nuclear mortgage, which devalues escalation to extremes. The reality of the first industrial and total war created an initial wave of pacifism in the 1920's. Today, the prospect of unmanageable escalation, the hypothesis, beyond a certain level of violence, of a post-total war curbs different forms of aggression. The image of war remains useful for peace. The third is the relative pacification of relations between major powers in the post-Cold War era. It is yet to be called into question by the re-distribution of power promised by the emergence of new major actors, at either the regional or global level. These three factors must continually be re-appraised. The de-legitimising of war is a cultural phenomenon and can thus evolve, either in a certain climate (as the U.S. 'folly' after 9/11 demonstrates), or in the long term (with a re-evaluation of confrontations between 'sides'). A subsidiary issue concerns how Europe, which is largely unable to psychologically and materially deal with the war hypothesis, would react to a re-brutalization of the world. The nuclear mortgage depends on the viability of the system that manages both nuclear power-projection and non-proliferation. In this respect the negotiations with Iran are

    1995-01-01

    In 1895, exactly one hundred years, ago, a chance discovery in Wurzburg, Germany, marked the dawn of a new science - atomic physics. Other discoveries and new insights followed quickly. Apart from interruptions for two World Wars, this rapid succession of breakthroughs continued for 88 years. A new series of occasional articles in the CERN Courier will look back to what was happening one century ago. In Wurzburg on 8 November 1895, Wilhelm Conrad Rôntgen became an immortal legend. Interested in the effects of ultra-violet radiation, he covered a cathode-ray discharge tube with black paper and darkened the room. With the glow from the tube hidden, Rôntgen was surprised to see a fluorescent screen two metres away light up. For several weeks, Rôntgen hid in his laboratory, finding out more about the mysterious penetrating 'X' rays, produced when the cathode rays hit the end of the discharge tube. Since the time of Faraday, the glow produced in an evacuated tube when an electric current was passed through had intrigued physicists and entertained the public. Nobody understood what these cathode rays were. William Crookes in the UK, who had narrowly missed making the Rôntgen discovery, surmised they were a new 'fourth state' of matter. Some scientists said the phenomena were due to radiation, others said particles. Also in 1895, a young physics student named Ernest Rutherford arrived in Britain from New Zealand with a scholarship for further study. The scholarship, awarded to a New Zealand student only once every few years, had initially been given to a young chemist, but who decided at the last minute to get married and stay in New Zealand. The scholarship passed to Rutherford, who, thanks to a change in regulations, was able to use it at the Cavendish Laboratory in Cambridge, under J.J. Thomson. In New Zealand, Rutherford had carried out experiments on radio telegraphy. He took his transmitter to Britain and at Cambridge continued his pioneer

  6. Can the ministry collaborate to form the "next generation" of sponsors?

    Science.gov (United States)

    Stanley, Teresa

    2007-01-01

    In looking to the future of sponsored ministry of Catholic institutions, the formation of future sponsors--both religious and lay alike--is an important issue. As this ministry continues to evolve, and sponsoring groups determine how best to prepare new sponsors, might it not be time to think about how to pool the ministry's collective wisdom on formation? Sponsors act not only in the name of the health care institution (or other ministry) but on behalf of the faith community engaged in continuing the compassionate healing ministry of Jesus. In Catholic ministry, and particularly health care ministry, sponsors carry out their responsibilities through a multiplicity of organizational relationships. Just as structures differ, so too do criteria that guide who will be called to join a sponsoring group. There are several core elements that are incorporated in the majority of sponsor competency sets. Elements identified by a committee of ministry members, and reviewed by hundreds of sponsors and other ministry leaders are: mission oriented, animated, theologically grounded, collaborative, church related, and accountable. If one is looking at the potential for convening dialogues about possible areas of collaboration in formation, these core elements, with examples of how they are lived out, may offer an outline of areas new sponsors might need to learn more about for their personal and professional development. Our Catholic health ministry depends on leaders who can create and steward organizational cultures that incarnate Jesus' healing. The possibilities for collaboration in the formation of future sponsors are endless, but there are challenges. If you are a member of a sponsor body/council/corporate member in Catholic health care, and are interested in nominating potential persons to take part in a representative group that would discuss possibilities for collaboration in sponsor formation, please go to www.chausa.org/sponsorformation and complete all sections of the

  10. The fragility of the Brazilian Defense Ministry

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available The present article presents different phases that the Brazilian Defense Ministry has passed through, since its inception during Fernando Henrique Cardoso's second presidential term (1999-2002 until the current administration of Luís Inácio Lula da Silva (2003-2006, under its respective ministers of Defense. It has been seen as one of the important stages in the re-constitutionalization of the country, insofar as it establishes the submission of Armed Forces commanders to a civilian minister, and although some analysts have considered that such submission is actually achieved, we point here to the military resistance and insubordination to civil power that are the result of an authoritarian legacy. To the extent that the Ministry of Defense is unable to implement its own policies in which the military would be required to follow civilian guidance, this article concludes with considerations on the civil Defense Ministry's political and institutional fragility vis-a-vis military command. The latter has been able to retain high levels of decision making autonomy in its relationship to the Ministry and its structure.

  11. Theology links Christian ministry with God's call.

    Science.gov (United States)

    O'Connell, L J

    1984-03-01

    Catholic health care ministry originates in and is shaped by the theme of call in the Old and New Testaments. To be specifically Catholic, health professionals and facilities must define their ministries according to the values expressed in this theological tradition. Sponsorship. The opportunity to provide health care enables religious communities to contribute to God's ongoing creation process and to reiterate Christ's call to minister to others. Although health care facility sponsorship thrusts religious communities into the arena of big business, the abandonment of the health care mission could be considered a betrayal of evangelical values. Quality of life. The implicit concern for human dignity that distinguishes Catholic health care facilities should be evident in personalized patient care, just working conditions, and a commitment to healing in the civic community. Stewardship in ethics. The development of business policies and procedures and institutional responses to social change should be carefully considered in light of the Catholic understanding of loving covenant and the Christian way of life. Shared ministry. Health care facilities have played a leading role in implementing the Second Vatican Council's vision of ministry. Sponsoring communities' continued willingness to share responsibilities with laity will be imperative in meeting the health care demands of the future.

  14. Asian American Evangelicals in Multiracial Church Ministry

    Directory of Open Access Journals (Sweden)

    Kathleen Garces-Foley

    2013-04-01

    Full Text Available Since the 1990s, evangelical efforts to create multiracial churches (MRCs have grown exponentially. This article analyzes the experiences of Asian American evangelical ministers leading MRCs. Through interviews we explore how Asian American evangelicals came to be involved in MRC-ministry and how they approach issues of racial diversity in this context. We compare the racial attitudes of Asian American evangelical ministers leading MRCs with those of White and Black evangelicals delineated in Emerson and Smith’s Divide by Faith. Rather than conform to the colorblind approach of many White evangelicals, the majority of our respondents utilize structural explanations for social inequality and promote a colorconscious approach to diversity. We conclude that Asian American evangelicals utilize a unique framework for MRC-ministry, what we call a ‘racialized multiculturalism,’ that has much to offer American evangelicalism.

    Continuous miners create dust and methane problems in underground coal mining. Control has usually been achieved using ventilation techniques as experiments with water based suppression have led to flooding and electrical problems. Recent experience in the US has led to renewed interest in wet head systems. This paper describes tests of the Hydraphase system by IMC Technologies. Ventilation around the cutting zone, quenching of hot ignition sources, dust suppression, the surface trial gallery tests, the performance of the cutting bed, and flow of air and methane around the cutting head are reviewed. 1 ref., 2 figs., 2 photos.

    Drawing upon experiences as a prison chaplain and a state director of prison chaplaincy services, the author proposes a working theology of prison ministry. Such a theology begins with an understanding of the inherent worth of humankind as created by God in God's own image, addresses the question of hope, embodies the incarnate presence of God by being present with people in their alienation, enables the giving and receiving of forgiveness, deals with issues of power and control, and respects the diverse paths that humans take in their walk toward and with God.

  18. The Ministry of Christ Embassy, Lagos. Nigeria

    T.A. Falaye

    2015-03-01

    Full Text Available The ministry of Christ Embassy is one of the fastest growing indigenous churches in Nigeria. The Church is quite attractive to the youths and has grown in bounds all over the country, especially in the Southern part of Nigeria. On the strength of its wide spread coverage, and the age group that the church attracts, the writer is of the opinion that highlighting her activities would be of benefit to church historians and others in church ministry. The writer employed both historical and sociological methodology in his article. It is recommended that the founder of the church should make attempt to translate his sermons and other materials to main languages in Nigeria. The advantage is that the church would be able to reach out to several others. In addition, there is the need for openness especially in the area of financial management in the church. The financial aspect is said to be locked-in between the leadership. It is noted by the writer that such transparency would build greater confidence in others who may desire to join the church in future.

  19. A "second generation" of ministry leadership.

    Giammalvo, Peter J

    2005-01-01

    Catholic health care leaders differ from others in the field in that "they are expected to serve as Jesus served, teach as Jesus taught, and lead as Jesus led, in order to heal as Jesus healed." The Catholic health ministry today is led largely by laypeople-what might be called the "first generation" of lay leaders. This first generation was privileged in that it was tutored by and worked alongside women and men religious. Those religious are now mostly gone from the ministry, and that first generation of lay leaders will also be retiring in the not too distant future. Leadership will then pass to a "second generation," laypeople who have not worked alongside religious. How is this new generation to learn "to heal as Jesus healed"? Catholic Health East (CHE), Newtown Square, PA, has developed a program explicitly directed at the recruitment and development of second-generation leaders. In its efforts to fill a position, the system first assembles a preferred-candidate profile, based on 15 competencies, including seven core competencies. CHE then employs a recruitment process based on behavioral event interviewing. All involved stakeholders participate in the interviews.

    Peden, W.

    1995-01-01

    A consultant for Greenpeace, the anti-nuclear campaigners, looks at the United Kingdom Government's problems with decommissioning of its nuclear submarine fleet as the vessels become obsolete, and at the transport and storage of spent fuels from the submarine's propulsion reactors. It is argued that no proper plans exist to decommission the vessels safely. The Ministry of Defence sites such as Rosyth and Devonport are immune from inspection by regulatory bodies, so there is no public knowledge of any potential radioactive hazards from the stored out-of-service carcasses, floating in dock, awaiting more active strategies. The author questions the wisdom of building new nuclear submarines, when no proper program exists to decommission existing vessels and their operational waste. (U.K.)

    2017-01-01

    Death is inevitable, but that does not mean it can be planned or imposed. It is an ethical imperative that we attend to the unbearable pain and suffering of patients with incurable and terminal illnesses. This is where palliative care plays a vital role. Palliative care has been growing faster in the world of medicine since its emergence as a specialty in the last decade. Palliative care helps to reduce physical pain while affirming the aspect of human suffering and dying as a normal process. The goal of palliative care is to improve the quality of life both of the patient and the family. Palliative care resonates with the healing ministry of Christianity that affirms the sanctity and dignity of human life from the moment of conception to natural death. Christianity is convinced that patients at the very end of their lives, with all their ailments and agonies, are still people who have been created in the image and likeness of God. The human person is always precious, even when marked by age and sickness. This is one of the basic convictions that motivate Christians to take care of the sick and the dying. Palliative care is a great opportunity for Christians to manifest God's unfailing love for the terminally ill and the dying.

  8. Plasma arc cutting: speed and cut quality

    International Nuclear Information System (INIS)

    Nemchinsky, V A; Severance, W S

    2009-01-01

    When cutting metal with plasma arc cutting, the walls of the cut are narrower at the bottom than at the top. This lack of squareness increases as the cutting speed increases. A model of this phenomenon, affecting cut quality, is suggested. A thin liquid layer, which separates the plasma from the solid metal to be melted, plays a key role in the suggested model. This layer decreases heat transfer from the plasma to the solid metal; the decrease is more pronounced the higher the speed and the thicker the liquid metal layer. Since the layer is thicker at the bottom of the cut, the heat transfer effectiveness is lower at the bottom. The decrease in heat transfer effectiveness is compensated by the narrowness of the cut. The suggested model allows one to calculate the profile of the cut. The result of the calculations of the cutting speeds for plates of various thicknesses, at which the squareness of the cut is acceptable, agrees well with the speeds recommended by manufacturers. The second effect considered in the paper is the deflection of the plasma jet from the vertical at a high cutting speed. A qualitative explanation of this phenomenon is given. We believe the considerations of this paper are pertinent to other types of cutting with moving heat sources.

    1993-07-01

    Full Text Available A laser cannot, as generally assumed by the layman, cut right through a diamond with a single cut. A couple of hundred cuts may be necessary to "chip carve" through a diamond. There are several parameters, for example cutting speed, focus point, overlapping of cuts, etc., that influence the cutting process. With a view to optimizing the cutting process, laser cuts in diamonds were studied in a systematic way with the aid of an electron microscope. The method, technique and the results of the research are discussed in this article.

    Although the specialty of palliative nursing and palliative care continues to grow in hospital and outpatient settings, a paucity of home-based palliative services remains. This article discusses a new paradigm of faith-based palliative care ministry using faith community nurses (FCNs). Under the leadership of a palliative care doula (a nurse expert in palliative care), nurses in the faith community can offer critical support to those with serious illness. Models such as this provide stimulating content for FCN practice and opportunity to broaden health ministry within faith communities.

    International Nuclear Information System (INIS)

    Berger, B.S.; Minis, I.; Rokni, M.

    1997-01-01

    Cutting states associated with the orthogonal cutting of stiff cylinders are identified through an analysis of the singular values of a Toeplitz matrix of third order cumulants of acceleration measurements. The ratio of the two pairs of largest singular values is shown to differentiate between light cutting, medium cutting, pre-chatter and chatter states. Sequences of cutting experiments were performed in which either depth of cut or turning frequency was varied. Two sequences of experiments with variable turning frequency and five with variable depth of cut, 42 cutting experiments in all, provided a database for the calculation of third order cumulants. Ratios of singular values of cumulant matrices find application in the analysis of control of orthogonal cutting

    The objectives of this study were to educate consumers about value-added beef cuts and evaluate their palatability responses of a value cut and three traditional cuts. Three hundred and twenty-two individuals participated in the beef value cut education seminar series presented by trained beef industry educators. Seminar participants evaluated tenderness, juiciness, flavor, and overall like of four samples, bottom round, top sirloin, ribeye, and a value cut (Delmonico or Denver), on a 9-point scale. The ribeye and the value cut were found to be similar in all four attributes and differed from the top sirloin and bottom round. Correlations and regression analysis found that flavor was the largest influencing factor for overall like for the ribeye, value cut, and top sirloin. The value cut is comparable to the ribeye and can be a less expensive replacement. © 2013.

    Full Text Available Introduction: The growth of social networks on the internet is visible. Everywhere people use these tools on various places, either via desktop, laptop, tablet or smartphone. In Brazil, the most prominent network in recent years is Facebook, which reached 76 million users in June 2013, an unprecedented number in the country. The growth allowed governments to perceive this virtual space as a potential place to present their work and communicate with society. Objectives: The study goal is to observe how information has been publicized by the Ministry of Health through Facebook since 2010 (year of creation of the page until October 2013, taking as an analytical category the implemented information policy, in order to propose a discussion about democratization of access to health information. Methodology: case study; Non-participant observation, data collection and documental analysis. Results: The main issues addressed by the Ministry of Health on Facebook are organizational actions and government programs instead of posts with guidance for a healthy living style. Also noteworthy is the low interaction of the Ministry page moderators with the users profile. The study showed most of the questions and comments made by the public are not answered by the institutional body. Conclusions: Need of strengthening the mediaton process of the information policies from the Ministry of Health on Facebook.

  7. Investigators find hundreds of intentional nuclear releases

    International Nuclear Information System (INIS)

    1994-01-01

    Investigators with the federal Advisory Committee on Human Radiation Experiments have said that the category of intentional releases is now known to be larger, in variety and quantity, than the 13 releases identified prior to the committee's formation in January 1994 by President Clinton. The committee is now aware of hundreds of additional intentional releases. In addition to the intentional releases, the committee said it had compiled documents on 400 biomedical experiments involving radiation prior to 1975, and had at least fragmentary evidence of more than 1,000 more. The committee also discovered a top secret 1953 Defense Department policy statement on human experimentation that was based on the World War II-era Nuremberg Code. The committee said it was looking into how or whether the policy was implemented. The committee is expected to issue a final report, including recommendations on possible compensation for victims by April 1995

  8. Minkowski Spacetime A Hundred Years Later

    CERN Document Server

    Petkov, Vesselin

    2009-01-01

    This volume is dedicated to the one hundredth anniversary of the publication of Hermann Minkowski's paper "Space and Time" in 1909. His work on the spacetime representation of special relativity had a huge impact on the twentieth century physics to the extent that modern physics would be impossible without the notion of spacetime. While there is consensus on the mathematical significance of spacetime in theoretical physics, for a hundred years there has been no consensus on the nature of spacetime itself. We owe Minkowski a clear answer to the question of the nature of spacetime -- whether it is only a mathematical space or represents a real four-dimensional world. A century after its publication the original Minkowski paper still represents an enrichment to the physicists, especially the relativists, who read it with the intent to fully investigate the depth of Minkowski's ideas on space and time and the physical meaning of special relativity. The volume begins with an excellent retranslation of Minkowski's ...

    1990-01-01

    The primary circuit structures of different nuclear powerplants are constructed out of stainless steels, ferritic steels, plated ferritic steels and alloys of aluminium. According to the level of the specific radiation of these structures, it is necessary for dismantling to work with remote controlled cutting techniques. The most successful way to protect the working crew against exposure of radiation is to operate underwater in different depths. The following thermal cutting processes are more or less developed to work under water: For ferritic steels only - flame cutting; For ferritic steels, stainless steels, cladded steels and aluminium alloys - oxy-arc-cutting, arc-waterjet-cutting with a consumable electrode, arc-saw-cutting, plasma-arc-cutting and plasma-arc-saw. The flame cutting is a burning process, all the other processes are melt-cutting processes. This paper explains the different techniques, giving a short introduction of the theory, a discussion of the possibilities with the advantages and disadvantages of these processes giving a view into the further research work in this interesting field.

    2010-11-01

    Full Text Available This survey of developments, guidelines and uses of technology by congregations and their leaders offers an overview of the topic and points to sources for further study. As technology plays a larger role in religious communities there is a need for guiding principles for its use. Congregational leaders do well to engage technology reflectively while staying informed on its possible applications in ministry. While this article is of primary interest to those in leadership positions at the congregational level, it can also serve both as a primer to seminary students and as a tool for librarians providing reference services on the topic.

  17. The Russian Federation's Ministry of Atomic Energy: Programs and Developments

    International Nuclear Information System (INIS)

    CM Johnson

    2000-01-01

    This paper reviews select programs driving the Ministry of Atomic Energy of the Russian Federation's (Minatom) efforts to raise funds, comments on their potential viability, and highlights areas likely to be of particular concern for the US over the next three to five years. The paper's findings are: (1) Despite numerous cabinet displacements throughout the Yeltsin administration, Yevgeny Adamov was reappointed Minister on four occasions. With Boris Yeltsin's January 1, 2000 resignation, Adamov's long-term position as the head of the Ministry is more tenuous, but he will likely retain his position until at least the March 2000 elections. Acting President Vladimir Putin is unlikely to reorganize his cabinet prior to that date and there are no signs that Putin is dissatisfied with Adamov's leadership of Minatom. (2) Adamov's chief priorities are downsizing Minatom's defense sector, increasing the oversight of subsidiary bodies by the central bureaucracy and consolidating commercial elements of the Ministry within an umbrella organization called Atomprom. (3) Viktor Mikhaylov, Adamov's predecessor and critic of his reform efforts, has been relieved of his duties as First Deputy Minister. While he retains his positions as Chief of the Science Councils and Chief Scientist at Arzamas-16, his influence on Minatom's direction is greatly diminished. Adamov will likely continue his efforts to further marginalize Mikhaylov in the coming year. (4) Securing extra-budgetary sources of income continues to be the major factor guiding Minatom's international business dealings. The Ministry will continue to aggressively promote the sale of nuclear technology abroad, often to countries with questionable nonproliferation commitments. (5) Given the financial difficulties in Russia and Minatom's client states, however, few nuclear development programs will come to fruition for a number of years, if ever. Nevertheless, certain peaceful nuclear cooperation agreements should be carefully

  3. Fundamentals of cutting.

    Science.gov (United States)

    Williams, J G; Patel, Y

    2016-06-06

    The process of cutting is analysed in fracture mechanics terms with a view to quantifying the various parameters involved. The model used is that of orthogonal cutting with a wedge removing a layer of material or chip. The behaviour of the chip is governed by its thickness and for large radii of curvature the chip is elastic and smooth cutting occurs. For smaller thicknesses, there is a transition, first to plastic bending and then to plastic shear for small thicknesses and smooth chips are formed. The governing parameters are tool geometry, which is principally the wedge angle, and the material properties of elastic modulus, yield stress and fracture toughness. Friction can also be important. It is demonstrated that the cutting process may be quantified via these parameters, which could be useful in the study of cutting in biology.

  8. Language as a barrier to ministry of the Word with special reference to sign language in ministry: Human dignity perspective

    Directory of Open Access Journals (Sweden)

    Leepo J. Modise

    2016-03-01

    Full Text Available This article is born out of my participation in the General Synod Ministerial Formation for theological training of Uniting Reformed Church in Southern Africa (URCSA, when a decision was taken to license a student with a disability to be a minister of the Word in URCSA. Furthermore, my experience and observation of the licensing of the two candidates with hearing impairments to the ministry of the Word and Sacrament in URCSA and Dutch Reformed Church in South Africa (DRCSA has encouraged me to conduct this research. This article is made up of four important parts: Firstly, the researcher will discuss Belhar Confession as the confession that emphasises unity (inclusivity, reconciliation and justice. Secondly, Belhar Confession and disability from the human dignity perspective will be discussed. Thirdly, the ecclesiological practices and shortcomings from the human dignity perspective will be highlighted. Fourthly, pastoral care as the affirmation of human dignity will be discussed.Interdisciplinary and/or interdisciplinary implications: The fields involved in this article are Systematic Theology, Sociology and Psychology. The author challenges classification of people with a disability under the category of limited competence by the Dutch Reformed Church when they license the ministerial candidates. The future results will reveal the inclusivity in terms of licensing and calling of ministers in the Dutch Reformed Church Family. This research calls for the change in the traditional discourse within ecclesiological, sociological and psychological fields, which exclude the people with a disability from the ministry of the Word and Sacraments.

    Experimental tests have been performed using CO 2 laser with output power 1 to 15 kW to evaluate the effect of varying the following parameters: material (carbon steel Fe 42 C, stainless steel AISI 304, concrete), laser power, beam characteristics, work piece velocity, gas type and distribution on the laser interaction zone. In the case of concrete, drilling depths of 80 mm were obtained in a few seconds using a 10 kW laser beam. Moreover pieces of 160 mm were cut at 0.01 meters per minute. Results with carbon steel indicated maximum thicknesses of 110 mm, cut at 0.01 meters per minute with 10 kW, depths about 20% lower were obtained with the AISI 304 stainless steel. A parallel investigation was aimed at characterizing particulate emission during the laser cutting process.

  19. Flux cutting in superconductors

    International Nuclear Information System (INIS)

    Campbell, A M

    2011-01-01

    This paper describes experiments and theories of flux cutting in superconductors. The use of the flux line picture in free space is discussed. In superconductors cutting can either be by means of flux at an angle to other layers of flux, as in longitudinal current experiments, or due to shearing of the vortex lattice as in grain boundaries in YBCO. Experiments on longitudinal currents can be interpreted in terms of flux rings penetrating axial lines. More physical models of flux cutting are discussed but all predict much larger flux cutting forces than are observed. Also, cutting is occurring at angles between vortices of about one millidegree which is hard to explain. The double critical state model and its developments are discussed in relation to experiments on crossed and rotating fields. A new experiment suggested by Clem gives more direct information. It shows that an elliptical yield surface of the critical state works well, but none of the theoretical proposals for determining the direction of E are universally applicable. It appears that, as soon as any flux flow takes place, cutting also occurs. The conclusion is that new theories are required. (perspective)

    The Quarter began with installing the new drill pipe, hooking up the new hydraulic power unit, completing the pipe rotation system (Task 4 has been completed), and making the SWACO choke operational. Detailed design and procurement work is proceeding on a system to elevate the drill-string section. The prototype Foam Generator Cell has been completed by Temco and delivered. Work is currently underway to calibrate the system. Literature review and preliminary model development for cuttings transportation with polymer foam under EPET conditions are in progress. Preparations for preliminary cuttings transport experiments with polymer foam have been completed. Two nuclear densitometers were re-calibrated. Drill pipe rotation system was tested up to 250 RPM. Water flow tests were conducted while rotating the drill pipe up to 100 RPM. The accuracy of weight measurements for cuttings in the annulus was evaluated. Additional modifications of the cuttings collection system are being considered in order to obtain the desired accurate measurement of cuttings weight in the annular test section. Cutting transport experiments with aerated fluids are being conducted at EPET, and analyses of the collected data are in progress. The printed circuit board is functioning with acceptable noise level to measure cuttings concentration at static condition using ultrasonic method. We were able to conduct several tests using a standard low pass filter to eliminate high frequency noise. We tested to verify that we can distinguish between different depths of sand in a static bed of sand. We tested with water, air and a mix of the two mediums. Major modifications to the DTF have almost been completed. A stop-flow cell is being designed for the DTF, the ACTF and Foam Generator/Viscometer which will allow us to capture bubble images without the need for ultra fast shutter speeds or microsecond flash system.

    2016-01-01

    Laser cutting has a huge importance to manufacturing industry. Laser cutting machines operate with fixed technological parameters and this does not guarantee the best productivity. The adjustment of the cutting parameters during operation can improve the machine performance. Based on a coaxial measuring device it is possible to identify the cut front position during the cutting process. This paper describes the data analysis approach used to determine the cut front position for different feed rates. The cut front position was determined with good resolution, but improvements are needed to make the whole process more stable. (paper)

    The Advanced Cuttings Transport Study (ACTS) was a 5-year JIP project undertaken at the University of Tulsa (TU). The project was sponsored by the U.S. Department of Energy (DOE) and JIP member companies. The objectives of the project were: (1) to develop and construct a new research facility that would allow three-phase (gas, liquid and cuttings) flow experiments under ambient and EPET (elevated pressure and temperature) conditions, and at different angle of inclinations and drill pipe rotation speeds; (2) to conduct experiments and develop a data base for the industry and academia; and (3) to develop mechanistic models for optimization of drilling hydraulics and cuttings transport. This project consisted of research studies, flow loop construction and instrumentation development. Following a one-year period for basic flow loop construction, a proposal was submitted by TU to the DOE for a five-year project that was organized in such a manner as to provide a logical progression of research experiments as well as additions to the basic flow loop. The flow loop additions and improvements included: (1) elevated temperature capability; (2) two-phase (gas and liquid, foam etc.) capability; (3) cuttings injection and removal system; (4) drill pipe rotation system; and (5) drilling section elevation system. In parallel with the flow loop construction, hydraulics and cuttings transport studies were preformed using drilling foams and aerated muds. In addition, hydraulics and rheology of synthetic drilling fluids were investigated. The studies were performed under ambient and EPET conditions. The effects of temperature and pressure on the hydraulics and cuttings transport were investigated. Mechanistic models were developed to predict frictional pressure loss and cuttings transport in horizontal and near-horizontal configurations. Model predictions were compared with the measured data. Predominantly, model predictions show satisfactory agreements with the measured data. As a

    Roadheaders are frequently used machines in mining and tunnelling, and performance prediction of roadheaders is important for project economics and stability. Several methods were proposed so far for this purpose and, rock cutting tests are the best choice. Rock cutting tests are generally divided into two groups which are namely, full scale rock cutting tests and small scale rock cutting tests. These two tests have some superiorities and deficiencies over themselves. However, in many cases, where rock sampling becomes problematic, small scale rock cutting test (core cutting test) is preferred for performance prediction, since small block samples and core samples can be conducted to rock cutting testing. Common problem for rock cutting tests are that they can be found in very limited research centres. In this study, a new mobile rock cutting testing equipment, vertical rock cutting rig (VRCR) was introduced. Standard testing procedure was conducted on seven rock samples which were the part of a former study on cutting rocks with another small scale rock cutting test. Results showed that core cutting test can be realized successfully with VRCR with the validation of paired samples t-test.

    1990-01-01

    At present in Japan the verification tests on the commercial nuclear power reactor decommissioning technology are being conducted as the project of The Ministry of International Trade and Industry by Nuclear Power Engineering Test Center. This paper summarizes the interim results of the verification test for the reactor core internals decommissioning technology, which is being conducted from 1986 as a theme of the above project. All core internals to be studied here are made of stainless steel, and the maximum wall thickness is about 500mm (the maximum one to be cut is about 300mm) for the PWR's, and about 100mm for the BWR's. Though the plasma cutting, arc saw cutting method, etc. have been studied u p to now as the cutting technology for decommissioning these core internals, the authors are carrying out the development and verification test of the cutting technology with the laser beam, which is expected to increase its power in future and can be applied to various materials

    The CO laser is superior in the absorption characteristic to materials to the CO 2 laser due to its shorter wavelength. In consideration of this characteristic Nuclear Power Engineering Corporation is studying this applicability sponsored by the Ministry of International Trade Industry of Japan to cutting of reactor core internals of commercial nuclear power plant. In decommissioning of reactor core internals it is necessary to cut stainless steel plates of 305 mm thick. The authors cut stainless steel plates of up to 310mm thick in air and those of up to 150 mm thick underwater with a 20kW class laser. Further, models simulating key structural elements of PWR core internals were cut and secondary products to clarify the applicability of the CO laser cutting to reactor core internals were evaluated.

    Unlike illusive magnetic field lines in vacuum, magnetic vortices in superconductors are real physical strings, which interact with the sample surface, crystal structure defects, and with each other. We address the complex and poorly understood process of vortex cutting via a comprehensive set of magneto-optic experiments which allow us to visualize vortex patterns at magnetization of a nearly twin-free YBCO crystal by crossing magnetic fields of different orientations. We observe a pronounced anisotropy in the flux dynamics under crossing fields and the filamentation of induced supercurrents associated with the staircase vortex structure expected in layered cuprates, flux cutting effects, and angular vortex instabilities predicted for anisotropic superconductors. At some field angles, we find formation of the vortex domains following a type-I phase transition in the vortex state accompanied by an abrupt change in the vortex orientation. To clarify the vortex cutting scenario we performed time-dependent Ginzburg-Landau simulations, which confirmed formation of sharp vortex fronts observed in the experiment and revealed a left-handed helical instability responsible for the rotation of vortices. This work was supported by the U.S. Department of Energy, Office of Science, Materials Sciences and Engineering Division.

  14. Remote Laser Cutting of CFRP: Improvements in the Cut Surface

    Science.gov (United States)

    Stock, Johannes; Zaeh, Michael F.; Conrad, Markus

    In the automotive industry carbon fibre reinforced plastics (CFRP) are considered as a future key material to reduce the weight of the vehicle. Therefore, capable production techniques are required to process this material in mass industry. E.g., state of the art methods for cutting are limited by the high tool wear or the feasible feed rate. Laser cutting processes are still under investigation. This paper presents detailed new studies on remote laser cutting of CFRP focusing on the influence of the material properties and the quality of the cut surface. By adding light absorbing soot particles to the resin of the matrix, the cutting process is improved and fewer defects emerge.

  15. Cutting agents for special metals

    1979-01-01

    The quantity of use of special metals has increased year after year in the Plasma Research Institute, Nagoya University, with the development of researches on plasma and nuclear fusion. Most of these special metals are hard to cut, and in order to secure the surface smoothness and dimensional accuracy, considerable efforts are required. The method of experiment is as follows: cutting agents salt water and acetone, rape-seed oil, sulfide and chloride oil and water soluble cutting oil W grade 3; metals to be cut niobium, molybdenum, tantalum, titanium and tungsten; cutting conditions cutting speed 4.7 to 90 m/min, feed 0.07 to 0.2 mm/rev, depth of cut 0.1 to 0.4 mm, tool cemented carbide bit. Chemicals such as tetrachloromethane and trichloroethane give excellent cutting performance, but the toxicity is intense and the stimulative odor exists, accordingly they are hard to use practically. Cutting was easier when the salt water added with acetone was used than the case of rape-seed oil, but salt water is corrosive. Recently, the machining of molybdenum has been often carried out, and the water soluble cutting oil was the best. It is also good for cutting stainless steel, and its lubricating property is improved by adding some additives such as sulfur, chlorine, phosphorus and molybdenum disulfide. However after cutting with it, washing is required. (Kako, I.)

    We have tested the loop elevation system. We raised the mast to approximately 25 to 30 degrees from horizontal. All went well. However, while lowering the mast, it moved laterally a couple of degrees. Upon visual inspection, severe spalling of the concrete on the face of the support pillar, and deformation of the steel support structure was observed. At this time, the facility is ready for testing in the horizontal position. A new air compressor has been received and set in place for the ACTS test loop. A new laboratory has been built near the ACTS test loop Roughened cups and rotors for the viscometer (RS300) were obtained. Rheologies of aqueous foams were measured using three different cup-rotor assemblies that have different surface roughness. The relationship between surface roughness and foam rheology was investigated. Re-calibration of nuclear densitometers has been finished. The re-calibration was also performed with 1% surfactant foam. A new cuttings injection system was installed at the bottom of the injection tower. It replaced the previous injection auger. A mechanistic model for cuttings transport with aerated mud has been developed. Cuttings transport mechanisms with aerated water at various conditions were experimentally investigated. A total of 39 tests were performed. Comparisons between the model predictions and experimental measurements show a satisfactory agreement. Results from the ultrasonic monitoring system indicated that we could distinguish between different sand levels. We also have devised ways to achieve consistency of performance by securing the sensors in the caps in exactly the same manner as long as the sensors are not removed from the caps. A preliminary test was conducted on the main flow loop at 100 gpm flow rate and 20 lb/min cuttings injection rate. The measured bed thickness using the ultrasonic method showed a satisfactory agreement with nuclear densitometer readings. Thirty different data points were collected after the test

This maneuver is the first step in a 3-point turn that will rotate the rover 115 degrees to face west. The rover must make this turn before rolling off the lander because airbags are blocking it from exiting from the front lander petal. Before this crucial turn took place, engineers instructed the rover to cut the final cord linking it to the lander. The turn took around 30 minutes to complete.

    Full Text Available The aim of the underlying study to this paper is to evaluate the audit committees in the government ministries in Namibia; by assessing their composition, the function and regulations that govern committees. The study used a qualitative approach of inquiry. A purposive sampling method was used as the researcher selected ministries with audit committees. Thematic and content analysis was used in this study. Both primary and secondary and data were used. On primary data, interviews were conducted and recorded with a voice recorder. Secondary data was during the review of existing literature on the subject. The study found that from the 4 government ministries with audit committees, only one ministry consisted of independent members as well as an independent chairperson, while 3 ministries are chaired by members within their organisations. There was clear evidence of lack of accounting / financial /auditing competence among the committee members. This trend is contrary to the best practice which requires that the chairperson of the audit committees be independent of the ministry as well as the members of the audit committee. The finding indicates possibility of lack of capacity to carry out the functions of audit committees; weak internal control systems; chances of conflict of interest and complacency due to the lack of independence. There is avenue for further research as more ministries in Namibia are now establishing their audit committees, especially as the Namibian Code of Corporate Governance (the NamCode gains more popularity among the public sector.

    Full Text Available The underlying study to this paper attempts to establish to what extent audit committees in government ministries in Namibia have been established as a requirement for enhanced quality of service delivery and accountability to taxpayers A qualitative approach was followed, where questionnaires or an interviews were conducted with accounting officers in government ministries. Content and thematic analyses were used to formulate narratives based on the understanding of similarities and differences in respondents’ experiences, views and perceptions. The study shows that from the 17 ministries that responded, only 2 ministries have established audit committees. Confirmatory, there is currently no legislature that makes it mandatory for government ministries in Namibia to establish audit committees within their respective constituencies. There are no formal audit committee terms and references or an audit committee charters are in place. Government ministries in Namibia seem to not have adopted best national and international governance practices with respect to the establishment of audit committees within their ministries. There is a need for a clear guidance as to how audit committees must be established; the composition of the committee members, the terms of office of committee members and remuneration, to mention a few

    The aim of presented work was the assessment of occupational radiation exposure and its distribution among the workers of Ministry of Defence and Ministry of Interior and Administration in the years 1986 - 2000. the research was conducted on the basis of data collected by Laboratory of Radiological Inspection and Individual Doses Control, Department of Radiation Protection and Radiobiology Military Institute of Hygiene and Epidemiology, Warsaw, Poland. The workers occupationally exposed to radiation were divided into following groups: government department (Ministry of Defence or Ministry of Interior and Administration), according to the age (below 25, 26-35, 36-45, 46-55 and above 56 years old), sex, education, (elementary, secondary, university) or job (doctors, nurses, rtg technicians, etc.). The number of workers covered with individual doses control changed in Ministry of Defence from 689 (in 1986) to 1030 (in 2000), and in Ministry of Interior and Administration from 261 to 924 in the same period. The percent of workers, who received doses below 2 mSv per year varied in Ministry of Defence from 91,6% (in 1997) to 99,4% (in 1990), and in Ministry of Interior and Administration from 96,8% (in 1993) to 99,4 (in 2000). Almost 99% of workers occupationally exposed to radiation and covered with individual doses control received doses below 15 mSv, irrespective of year or department. The analysis of collected data revealed, that for a large majority of occupationally exposed workers the risk arising from contact with ionizing radiation is minimal (over 99% of workers covered with individual doses control received doses below 2 mSv per year), however there are critical groups of workers, for which the received equivalent doses were about 30 - 50 mSv. Increased doses of radiation, however not exceeding obligatory limits, are noticed for workers taking part in surgical operations in X radiation field, urologic operations and diagnostic and or working on several

  5. Leptogenesis: The other cuts

    International Nuclear Information System (INIS)

    Garbrecht, Bjoern

    2011-01-01

    For standard leptogenesis from the decay of singlet right-handed neutrinos, we derive source terms for the lepton asymmetry that are present in a finite density background but absent in the vacuum. These arise from cuts through the vertex correction to the decay asymmetry, where in the loop either the Higgs boson and the right-handed neutrino or the left-handed lepton and the right-handed neutrino are simultaneously on-shell. We evaluate the source terms numerically and use them to calculate the lepton asymmetry for illustrative points in parameter space, where we consider only two right-handed neutrinos for simplicity. Compared to calculations where only the standard cut through the propagators of left-handed lepton and Higgs boson is included, sizable corrections arise when the masses of the right-handed neutrinos are of the same order, but the new sources are found to be most relevant when the decaying right-handed neutrino is heavier than the one in the loop. In that situation, they can yield the dominant contribution to the lepton asymmetry.

    1998-01-01

    The laser has given manufacturing industry a new tool. When the laser beam is focused it can generate one of the world's most intense energy sources, more intense than flames and arcs, though similar to an electron beam. In fact the intensity is such that it can vaporise most known materials. The laser material processing industry has been growing swiftly as the quality, speed and new manufacturing possibilities become better understood. In the fore of these new technologies is the process of laser cutting. Laser cutting leads because it is a direct process substitu­ tion and the laser can usually do the job with greater flexibility, speed and quality than its competitors. However, to achieve these high speeds with high quality con­ siderable know how and experience is required. This information is usually carefully guarded by the businesses concerned and has to be gained by hard experience and technical understanding. Yet in this book John Powell explains in lucid and almost non­ technical language many o...

  9. Aerodynamic Interactions During Laser Cutting

    Science.gov (United States)

    Fieret, J.; Terry, M. J.; Ward, B. A.

    1986-11-01

    Most laser cutting systems utilise a gas jet to remove molten or vaporised material from the kerf. The speed, economy and quality of the cut can be strongly dependent on the aerodynamic conditions created by the nozzle, workpiece proximity and kerf shape. Adverse conditions can be established that may lead to an unwelcome lack of reproducibility of cut quality. Relatively low gas nozzle pressures can result in supersonic flow in the jet with its associated shock fronts. When the nozzle is placed at conventional distances (1-2mm) above the workpiece, the force exerted by the gas on the workpiece and the cut products (the cutting pressure) can be significantly less than the nozzle pressure. Higher cutting pressures can be achieved by increasing the height of the nozzle above the workpiece, to a more damage resistant zone, provided that the shock structure of the jet is taken into account. Conventional conical nozzles with circular exits can be operated with conditions that will result in cutting pressures up to 3 Bar (g) in the more distant zone. At higher pressures in circular tipped nozzles the cutting pressure in this zone decays to inadequate levels. Investigations of a large number of non-circular nozzle tip shapes have resulted in the selection of a few specific shapes that can provide cutting pressures in excess of 6 Bar(g) at distances of 4 to 7mm from the nozzle tip. Since there is a strong correlation between cutting pressure and the speed and quality of laser cutting, the paper describes the aerodynamic requirements for achieving the above effects and reports the cutting results arising from the different nozzle designs and conditions. The results of the work of other investigators, who report anomalous laser cutting results, will be examined and reviewed in the light of the above work.

    Final design of the mast was completed (Task 5). The mast is consisting of two welded plate girders, set next to each other, and spaced 14-inches apart. Fabrication of the boom will be completed in two parts solely for ease of transportation. The end pivot connection will be made through a single 2-inch diameter x 4 feet-8 inch long 316 SS bar. During installation, hard piping make-ups using Chiksan joints will connect the annular section and 4-inch return line to allow full movement of the mast from horizontal to vertical. Additionally, flexible hoses and piping will be installed to isolate both towers from piping loads and allow recycling operations respectively. Calibration of the prototype Foam Generator Cell has been completed and experiments are now being conducted. We were able to generate up to 95% quality foam. Work is currently underway to attach the Thermo-Haake RS300 viscometer and install a view port with a microscope to measure foam bubble size and bubble size distribution. Foam rheology tests (Task 13) were carried out to evaluate the rheological properties of the proposed foam formulation. After successful completion of the first foam test, two sets of rheological tests were conducted at different foam flow rates while keeping other parameters constant (100 psig, 70F, 80% quality). The results from these tests are generally in agreement with the previous foam tests done previously during Task 9. However, an unanticipated observation during these tests was that in both cases, the frictional pressure drop in 2 inch pipe was lower than that in the 3 inch and 4 inch pipes. We also conducted the first foam cuttings transport test during this quarter. Experiments on aerated fluids without cuttings have been completed in ACTF (Task 10). Gas and liquid were injected at different flow rates. Two different sets of experiments were carried out, where the only difference was the temperature. Another set of tests was performed, which covered a wide range of

  17. Health Care Sharing Ministries and Their Exemption From the Individual Mandate of the Affordable Care Act.

    Science.gov (United States)

    Galarneau, Charlene

    2015-06-01

    The U.S. 2010 Patient Protection and Affordable Care Act (ACA) exempts members of health care sharing ministries (HCSMs) from the individual mandate to have minimum essential insurance coverage. Little is generally known about these religious organizations and even less critical attention has been brought to bear on them and their ACA exemption. Both deserve close scrutiny due to the exemption's less than clear legislative justification, their potential influence on the ACA's policy and ethical success, and their salience to current religious liberty debates surrounding the expansion of religious exemptions from ACA responsibilities for both individuals and corporations. Analyzing documents of the United States' three largest health care sharing ministries and related material, I examine these organizations and their ACA exemption with particular consideration of their ethical dimensions. Here a thick description of the nature and workings of health care sharing ministries precedes a similar account of the ACA exemption. From these empirical analyses, five ethical and policy concerns emerge: (1) the charity versus insurance status of these ministries; (2) the conflation of two ACA religious exemptions; (3) the tension between the values of religious liberty and of justice; (4) the potential undermining of ACA policy goals; and (5) the questionable compliance of health care sharing ministries with ACA exemption requirements.  An accurate and informed understanding of HCSMs is required for policymakers and others to justify the ACA exemption of health care sharing ministry members. A sufficient justification would address at least the five ethical and policy concerns raised here.

    Many physicists believe that after the discoveries of Max Planck (1900) and Albert Einstein (1905) physics was quickly transformed into a modern one based on relativistic and quantum principles. The study of the physics community and the physics papers published hundred years ago, in 1909, shows however, that only very few physicists took interest in the novelties while the bulk of physics remained classical and much oriented towards practical applications. Details are given on the physics topics, the strength of physics in various countries, the most important periodicals and prominent physicists of that time. (author)

    A hand held hydraulic cutting tool was developed which is particularly useful in deactivating ejection seats in military aircraft rescue operations. The tool consists primarily of a hydraulic system composed of a fluid reservoir, a pumping piston, and an actuator piston. Mechanical cutting jaws are attached to the actuator piston rod. The hydraulic system is controlled by a pump handle. As the pump handle is operated the actuator piston rod is forced outward and thus the cutting jaws are forced together. The frame of the device is a flexible metal tubing which permits easy positioning of the tool cutting jaws in remote and normally inaccessible locations. Bifurcated cutting edges ensure removal of a section of the tubing or cable to thereby reduce the possibility of accidental reactivation of the tubing or cable being severed.

    A place of material to be cut is surrounded by an openable/closable box. The material to be cut is cut underwater, and materials generated in this case are removed from the cut portion by a pressurized water jet. The removed materials are sucked and recovered together with water in the box. Among the materials caused by the cutting underwater, solid materials not floating on water are caused to stay in the midway of a sucking and recovering channel. A large sucking force might be required for the entire region of the sucking and recovering channel when sucking and recovering large sized solid materials not floating on water, but even large sized materials can be recovered easily according to the present invention since they are recovered after being sucked and stayed in the midway of the sucking and recovering channel.

    Reactive species are produced in biological system because of redox reactions. The imbalance in pro-oxidant and antioxidant homeostasis leads to the production of toxic reactive oxygen and nitrogen species like hydrogen peroxide, organic peroxides, hydroxyl radicals, superoxide anion and nitric oxide. Inactivation of metabolic enzymes, oxidation of biomolecules and cellular damage are some of the prominent characteristics of reactive species. Similarly, oxidative stress has been associated with more than one hundred (100) pathologies such as atherosclerosis, diabetes, cardiovascular diseases, pancreatic and liver diseases, joint disorders, cardiac fibrosis, acute respiratory distress syndrome, neurological diseases (amyotrophic lateral sclerosis, Huntington's disorder, Parkinson's disease and Alzheimer's disease), ageing and cancer etc. The toxicity of reactive species is balanced by the integrated antioxidant systems, which include enzymatic and non-enzymatic antioxidants. Antioxidant therapies or defenses protect the biological sites by removing or quenching the free radicals (prooxidants). Medicinal plants can not only protect the oxidative damage, but also play a vital role in health maintenance and prevention of chronic degenerative diseases. This review will provide a valuable discussion of one hundred (100) well known medicinal plants, which may add to the optimization of antioxidants rank. Besides, some of the antioxidant evaluation techniques or mechanisms via which medicinal plants act as antioxidants are also described.

  11. The "new masculinity": addiction treatment as a reconstruction of gender in Puerto Rican evangelist street ministries.

    Science.gov (United States)

    Hansen, Helena

    2012-06-01

    This article, based on ethnographic fieldwork including twelve months of participant observation and 428 interviews with 84 converts and leaders in Pentecostal ministries founded and run by former addicts in Puerto Rico, describes redefined masculinity as a treatment for addiction. Industrial disinvestment and resulting unemployment and drug trade in urban North and Latin America have led to narcotic addiction among Latino and African American men and attendant homicide, infection, and incarceration. Pentecostal-evangelical street ministries are prevalent in these regions. Their alternative vision of masculine honor and power addresses a cultural crisis of men's social space. They replace the unachievable ideal of the male breadwinner with an image of male spiritual power. In place of the violence of the drug trade, they cultivate male domesticity and responsibility for the home. In place of a deleterious drug economy, they offer the social and cultural capital of ministry networks and biblical knowledge. Yet the trajectories of ministry converts reveal the limits, as well as the promise, of evangelist masculinity as a treatment for addiction. In the course of building leadership among their converts, the ministries create their own, internal hierarchies, fall short of the spiritual democracy they espouse, and lead to relapse among those left at the bottom.

  12. A (South African voice on youth ministry research: Powerful or powerless?

    2015-11-01

    Full Text Available Research on youth ministry in Africa and specifically South Africa traces its origin to much research conducted in America and Europe. Many African scholars also draw on research and practices within these international spheres. Empirical research on youth ministry in Africa is however of great importance. For this purpose, comparative analysis research provides a research methodology in the social sciences that aims to make comparisons across different countries or cultures. A major problem in comparative research is that the data sets in different countries may not use the same categories, or define categories differently. This article makes use of a faith formation case study conducted in South Africa to highlight the value of this methodology when reflecting on international research from an African perspective. The main argument of this article is that international research on youth ministry is valuable in an African context but this research needs to be culturally contextualised through using comparative analysis as a research tool. This will reflect that there are many similarities between international youth ministry and the African context but there are also many cross-cultural disparities. After comparison, differences that are unique to the African context are noted. The article focuses on South Africa as a reflection of youth ministry within the broader African context.

    Patients as Partners is a quality improvement initiative of the British Columbia Ministry of Health (the Ministry) that aims to bring patient voice, choice, and representation to the forefront of healthcare through collaboration with patients, families, non-governmental organizations, funded partners, regional health authorities, and healthcare providers. A spectrum of patient engagement activities, including capacity building and self-management support, occur through partnerships at the individual patient and provider, community, and system levels. These activities ensure patient priorities are identified and embed a patient-centred care approach into provincial policies and projects. Multi-/interdisciplinary collaborations in the healthcare sector occur through participation in working groups, advisory committees, and engagement events. Ongoing improvements include enhancing measurement strategies and leveraging opportunities around gaps. The Ministry was honoured with the International Association of Public Participation Award as the 2016 Canadian Organization of the Year in recognition of improving healthcare through patient and public education.

    A femtosecond (fs) laser has been used as a tool for solving many problems involving access, machining, disassembly, inspection and avoidance of undesirable hazardous waste streams in systems containing energetic materials. Because of the unique properties of the interaction of ultrashort laser pulses with matter, the femtosecond laser can be used to safely cut these energetic materials in a precise manner without creating an unacceptable waste stream. Many types of secondary high explosives (HE) and propellants have been cut with the laser for a variety of applications ranging from disassembly of aging conventional weapons (demilitarization), inspection of energetic components of aging systems to creating unique shapes of HE for purposes of initiation and detonation physics studies. Hundreds of samples of energetic materials have been cut with the fs laser without ignition and, in most cases, without changing the surface morphology of the cut surfaces. The laser has also been useful in cutting nonenergetic components in close proximity to energetic materials. (Abstract Copyright [2003], Wiley Periodicals, Inc.)

    Full Text Available Article is devoted to the history of appearance of the Ministry of Public education in the domestic historiography. The author sets oneself the task of observing a scientifi c study of activities of the Public education Ministry at the initial stage of its existence and revealing not studied aspects of this question. First researches of educational reforms implemented by Alexander I go back to 60 years of the 21th century. Works done by M. N. Suhomlinov and S. V. Rojdestvenskiy are rich with archives materials, they show succession of the instructive reforms made by Ekaterina II and Alexander I, the connection between the arrangement of public education in France, Poland and Germany with Russian educational system at the end of the 18 and beginning of the 19 centuries. During the post revolutionary period in scientific literature less attention was paid to the questions of initial period of existence of the Ministry of Public Education. At the end of the 20th and the beginning of the 21th centuries scientists turned their attention again to the history of education system development in Russia. A large number of works of the modern day researches on university subject appeared and a qualitatively new period of study of the Public Education Ministry activities began. In F. A. Petrov’s monograph the major documents accepted by the ministry are analysed. A. Yu. Andreyev, studying the question of sources of a university autonomy in Russia, included domestic universities in the all-European context of development of university reforms. But despite the existing historiography, the initial stage of existence of the Ministry of Public education demands further researches.

  16. [Late Becker's nevus. One hundred cases (author's transl)].

    The authors make a survey of a series of a hundred Becker's nevi diagnosed in a recruiting center of the French National Service. It is a statistic study bearing on the male population, aged 17 to 26, in a French region which is supposed to be representative of the French male population of the same age. First of all the authors focus on the various clinical descriptions since this nevus was first described by Becker in 1949, then discuss the problems raised by pathogenic interpretation and the results of microscopic studies. About this lesion, usually said to be pigmentary and hairy, and generally appearing before 20 years of age, is still very little known. Then after a short explanation of their method of study the authors give original results. A hundred Becker's nevi were diagnosed among 19,302 young men, that is to say in a proportion of 0.52 p. 100. A study of the racial, genetic and pigmentary background doesn't enable to retain general causes but rather leads to think of local causes. Half of these Becker's nevi appeared before ten years of age, the other half appearing between 10 and 20. In only one quarter of the cases can the role of the sun be pointed out. The location of the nevi is variable; they are mainly situated on the trunk and only 32 p. 100 of them are located above nipples, which was believed to be the usual place of the lesion. Pigmentation in three quarter of the cases is light brown. The average surface is 125 cm2. Hairs can be seen in only a little more than half of the cases of no lesion associated to the nevus could be found. The study points out that Becker's nevi seem to be more various in their clinical expression and more pigment than could be thought through more classical description.

    The contribution of Regge cuts to single-particle inclusive processes is analyzed using the techniques of Gribov. The dependence of these contributions on the polarization state of the target is emphasized. A general formula is obtained and certain contributions to it are calculated. It is not possible, however, to reduce this to a simple, powerful formula expressing the total cut contribution in terms of other measurable quantities, as can be done for the cut contribution to the total cross section. The reasons for this are discussed in detail. The single-particle intermediate states, analogous to the absorption model for elastic scattering, are explicitly calculated as an illustration

    An investigation has been conducted of the use of laser energy for cutting contours, diameters, and holes in flat and shaped Kevlar 49 fiber-reinforced epoxy laminates as an alternate to conventional machining. The investigation has shown that flat laminates 6.35 mm thick may be cut without backup by using a high-powered (1000-watt) continuous wave CO/sub 2/ laser at high feedrates (33.87 mm per second). The cut produced was free of the burrs and delaminations resulting from conventional machining methods without intimate contact backup. In addition, the process cycle time was greatly reduced.

  3. Regge cuts: A general approach

    International Nuclear Information System (INIS)

    Weis, J.H.

    1976-01-01

    We discuss an approach to the calculation of Regge-cut contributions to scattering amplitudes which relies only on the general structure of the physical Reggeon couplings. It thus allows a unified treatment of disparate models [such as the Feynman (Mandelstam) graph model and the dual model] and a general derivation of the Abramovskii--Gribov--Kancheli (AGK) rules. The structure of the Reggeon couplings is expressed through integrals over complex helicity. The Regge-cut amplitude can then be obtained, and its s-channel discontinuity, taken; there results a direct derivation of a set of ''cutting rules'' which express the total discontinuity as a sum of terms involving various discontinuities of the Reggeon couplings. The equality of these discontinuities follows directly if the singularities in complex helicity are the usual ones. Thus the AGK rules are seen to be quite model independent. Here we study in detail the simplest example: the Reggeon-particle cut in the four-particle amplitude

    The selection of proper tool steel for a given application is a difficult task. So; the most important selection factors in choosing cutting tool materials are based on their tool material requirements, cutting tool design and service conditions which is mainly considered as functional requirements. The processability requirements concerns in heat treat ability of the material tool. The classification of these tool materials were discussed with their properties requirement and percent of alloying element which is added to give best properties with a little increase in cost that highly appear in comparison of the selection. The cutting tool materials were evaluated based on two cases; The first was in case of rough surface; the high speed steels is the best material and the other was the ceramic material is the highest performance in cutting of soft or high rate of metal removal.

    The laser cutting of color metals and alloys by a thickness more than 2 mm has significant difficulties due to high reflective ability and large thermal conduction. We made it possible to raise energy efficiency and quality of laser cutting by using a laser processing system (LPS) consisting both of the YAG:Nd laser with passive Q-switching on base of LiF:F2- crystals and the CO2 laser. A distinctive feature of the LPS is that the radiation of different lasers incorporated in a coaxial beam has simultaneously high level of peak power (more than 400 kW in a TEM00 mode) and significant level of average power (up to 800 W in a TEM01 mode of the CO2 laser). The application of combined radiation for cutting of an aluminum alloy of D16 type made it possible to decrease the cutting energy threshold in 1.7 times, to increase depth of treatment from 2 up to 4 mm, and velocity from 0.015 up to 0.7 m/min, and also to eliminate application of absorptive coatings. At cutting of steels the velocity of treatment was doubled, and also an oxygen flow was eliminated from the technological process and replaced by the air. The obtained raise of energy efficiency and quality of cutting is explained by an essential size reducing of a formed penetration channel and by the shifting of a thermal cutting mode from melting to evaporation. The evaluation of interaction efficiency of a combined radiation was produced on the basis of non-stationary thermal-hydrodynamic model of a heating source moving as in the cutting direction, and also into the depth of material.

    Bone cutting error can be one of the causes of malalignment in unicompartmental knee arthroplasty (UKA). The amount of cutting error in total knee arthroplasty has been reported. However, none have investigated cutting error in UKA. The purpose of this study was to reveal the amount of cutting error in UKA when open cutting guide was used and clarify whether cutting the tibia horizontally twice using the same cutting guide reduced the cutting errors in UKA. We measured the alignment of the tibial cutting guides, the first-cut cutting surfaces and the second cut cutting surfaces using the navigation system in 50 UKAs. Cutting error was defined as the angular difference between the cutting guide and cutting surface. The mean absolute first-cut cutting error was 1.9° (1.1° varus) in the coronal plane and 1.1° (0.6° anterior slope) in the sagittal plane, whereas the mean absolute second-cut cutting error was 1.1° (0.6° varus) in the coronal plane and 1.1° (0.4° anterior slope) in the sagittal plane. Cutting the tibia horizontally twice reduced the cutting errors in the coronal plane significantly (Pcutting the tibia horizontally twice using the same cutting guide reduced cutting error in the coronal plane.

    Most low- and middle-income countries face financing pressures if they are to adequately address the recommendations of the Global Strategy for Women's, Children's and Adolescent's Health. Negotiations between government ministries of health and finance are a key determinant of the level and effectiveness of public expenditure in the health sector. Yet ministries of health in low- and middle-income countries do not always have a good record in obtaining additional resources from key decision-making institutions. This is despite the strong evidence about the affordability and cost-effectiveness of many public health interventions and of the economic returns of investing in health. This article sets out 10 attributes of effective budget requests that can address the analytical needs and perspectives of ministries of finance and other financial decision-makers. We developed the list based on accepted economic principles, a literature review and a workshop in June 2015 involving government officials and other key stakeholders from low- and middle-income countries. The aim is to support ministries of health to present a more strategic and compelling plan for investments in the health of women, children and adolescents.

    In Third World countries a key to the course of nation-building is the modernization of the organizational and administrative infrastructures which drive the development process. Increasing the operational capabilities, effectiveness, and efficiency of the ministry of education, and hence the quality and quantity of school outcomes, is typically a high priority item in the development plans of a nation. In order to promote the modernization of management activities in ministries, however, it is first essential to understand their existing patterns of operation. Toward this objective, the paper presents a methodological framework for a field study approach to the examination of the working of a ministry of education in Latin America. Several issues are introduced which influence the process of inquiry, such as: (1) examining the impact of historical traditions on contemporary management procedures; (2) exploring concerns for ethics and academic colonialism; (3) distinguishing between anthropological and sociological participant-observation field methods; (4) gathering and analyzing data on complex ministries; and (5) exploring the task of Third World theory building.

These claims are illustrated with examples.

  1. Risk assessment for implementing e-services in some ministries in the State of Kuwait

    2007-01-01

    The movement to e-government is basically about changing the way people and business interact with government. Kuwait, like any developing country, is currently launching major e-service projects aiming at improving government processes, connect government to citizens, and build interaction within the civil society. The e-services category of e-government applications enables interactions and relationships between the government and citizens, through which the latter gain access to a range of public services. However, the implementation process of e-services involves many factors of risk that could threaten the success of process. Therefore, an effective risk management process is an important component of a successful information security program. This paper investigates and discusses the possibilities of e-services risk areas and assesses the security and privacy protection issues in some ministries in Kuwait. The results show that the total average percentage of applying security and privacy issues in the studied ministries is moderate. The Ministry of Communication (MoC) has the highest percentage of applications, whereas the Ministry of Trading and Industry (MoTI) has the lowest. Physical security is the highest applied variable, while prevention of unauthorized access is the lowest one. (author)

  2. Implenting family planning in a Ministry of Health: organizational barriers at the state and district levels.

    Simmons, R S; Ashraf, A

    1978-01-01

    1. Family planning occupied a subordinate position in the medical and health bureaucracy almost two decades after its introduction. Senior Ministry officials accorded low priority to formal program objectives, while the State Family Planning Officer, the highest state official concerned solely with the family planning program, suffered from a relatively subordinate position in the Directorate and a lack of authority and support. Within the medical profession, family planning was held in low esteem, and the medical and health bureaucracies did not have a mechanism for selecting personnel on the basis of interest and commitment. 2. Organizational adjustment to family planning in the Ministry of Health was a slow and painful process, absorbing the energy and attention of Ministry officials for almost a decade. The repeated reorganizations of the district setup revolving around the division of labor between medical, health, and family planning acitvities and between the rural and urban program, led to months of almost total inertia and detracted substantially from the supervisory capacity of the officials involved. 3. Decision making and guidance suffered from the quick turnover of the Secretary, the most powerful administrator in the Ministry. In Uttar Pradesh Secretaries stayed barely long enough to begin to understand the complex organizational setup of the program. 4. Multiple and often conflicting lines of authority characterized the relationships between the higher and lower echelons within the Ministry. This was accentuated when the District Family Planning Officer was placed under the administrative control of the District Magistrate. While intended to "energize" family planning through the association of the most prestigious and powerful district official with the program, this organizational arrangement resulted in conflicting instructions to the staffs of the primary health centers. 5. The organizational behavior of the Ministry of Health was shaped by the

  3. Antoine Marfan and his syndrome: one hundred years later.

    1998-11-01

    In 1896, in the Bulletin of the Medical Society of Paris, Antoine Marfan described a five-year-old girl with arachnodactyly. It took almost 50 years to fully elucidate this syndrome including aneurysm of the ascending aorta. It is critical to make an early diagnosis of Marfan aneurysm because there is a high frequency of dissection and rupture once the aortic diameter reaches 6 cm. Before the availability of the Bentall composite graft procedure in 1968, the operative results were very poor. The Bentall operation now carries a 30-day mortality rate of less than 5% at major cardiac surgical centers. Two hundred and thirty-one Marfan patients underwent aortic root replacement at The Johns Hopkins Hospital between September 1976 and December 1997. The 30-day mortality for 198 patients undergoing elective aortic root replacement was 0%. Two of 33 patients undergoing urgent surgery died in the first 30 days after surgery; both of these patients arrived in the operating room with ruptured aortas. The actuarial survival for the 231 patients undergoing aortic root replacement was 88% at five years, 81% at ten years, and 75% at 20 years. Clearly, the outlook for Marfan patients undergoing elective aortic root replacement has been excellent. Accompanying the steadily improving surgical results have been spectacular developments in understanding the genetic role in Marfan families. Since 1991, over 150 mutations have been discovered in the gene that is critical in the production of the structural protein fibrillin. The identification of mutations in the fibrillin gene has enabled the diagnosis of Marfan disease in some patients before they become symptomatic; prenatal diagnosis has been achieved in some patients. The ultimate hope for Marfan families is to eliminate the disease by genetic manipulation; however, this may be years away.

  4. One hundred years of return period: Strengths and limitations

    Volpi, E.; Fiori, A.; Grimaldi, S.; Lombardo, F.; Koutsoyiannis, D.

    2015-10-01

    One hundred years from its original definition by Fuller, the probabilistic concept of return period is widely used in hydrology as well as in other disciplines of geosciences to give an indication on critical event rareness. This concept gains its popularity, especially in engineering practice for design and risk assessment, due to its ease of use and understanding; however, return period relies on some basic assumptions that should be satisfied for a correct application of this statistical tool. Indeed, conventional frequency analysis in hydrology is performed by assuming as necessary conditions that extreme events arise from a stationary distribution and are independent of one another. The main objective of this paper is to investigate the properties of return period when the independence condition is omitted; hence, we explore how the different definitions of return period available in literature affect results of frequency analysis for processes correlated in time. We demonstrate that, for stationary processes, the independence condition is not necessary in order to apply the classical equation of return period (i.e., the inverse of exceedance probability). On the other hand, we show that the time-correlation structure of hydrological processes modifies the shape of the distribution function of which the return period represents the first moment. This implies that, in the context of time-dependent processes, the return period might not represent an exhaustive measure of the probability of failure, and that its blind application could lead to misleading results. To overcome this problem, we introduce the concept of Equivalent Return Period, which controls the probability of failure still preserving the virtue of effectively communicating the event rareness.

    Cake cutting is a fundamental model in fair division; it represents the problem of fairly allocating a heterogeneous divisible good among agents with different preferences. The central criteria of fairness are proportionality and envy-freeness, and many of the existing protocols are designed...... to guarantee proportional or envy-free allocations, when the participating agents follow the protocol. However, typically, all agents following the protocol is not guaranteed to result in a Nash equilibrium. In this paper, we initiate the study of equilibria of classical cake cutting protocols. We consider one...... of the simplest and most elegant continuous algorithms -- the Dubins-Spanier procedure, which guarantees a proportional allocation of the cake -- and study its equilibria when the agents use simple threshold strategies. We show that given a cake cutting instance with strictly positive value density functions...

    Spectral features from polycyclic aromatic hydrocarbon (PAH) molecules observed in the mid-infrared (mid-IR) range are typically used to infer the amount of recent and ongoing star formation on kiloparsec scales around active galactic nuclei (AGN) where more traditional methods fail. This method assumes that the observed PAH features are excited predominantly by star formation. With current ground-based telescopes and the upcoming James Webb Space Telescope, much smaller spatial scales can be probed and we aim at testing if this assumption still holds in the range of few tens to few hundreds of parsecs. For that, we spatially map the emitted 11.3 μm PAH surface flux as a function of distance from 0.4-4 arcsec from the centre in 28 nearby AGN using ground-based high-angular-resolution mid-IR spectroscopy. We detect and extract the 11.3 μm PAH feature in 13 AGN. The fluxes within each aperture are scaled to a luminosity-normalized distance from the nucleus to be able to compare intrinsic spatial scales of AGN radiation spanning about two orders of magnitude in luminosity. For this, we establish an empirical relation between the absorption-corrected X-ray luminosity and the sublimation radius in these sources. Once normalized, the radial profiles of the emitted PAH surface flux show similar radial slopes, with a power-law index of approximately -1.1, and similar absolute values, consistent within a factor of a few of each other as expected from the uncertainty in the intrinsic scale estimate. We interpret this as evidence that the profiles are caused by a common compact central physical process, either the AGN itself or circumnuclear star formation linked in strength to the AGN power. A photoionization-based model of an AGN exciting dense clouds in its environment can reproduce the observed radial slope and confirms that the AGN radiation field is strong enough to explain the observed PAH surface fluxes within ∼10-500 pc of the nucleus. Our results advice caution

  9. Document segmentation via oblique cuts

    2013-01-01

    This paper presents a novel solution for the layout segmentation of graphical elements in Business Intelligence documents. We propose a generalization of the recursive X-Y cut algorithm, which allows for cutting along arbitrary oblique directions. An intermediate processing step consisting of line and solid region removal is also necessary due to presence of decorative elements. The output of the proposed segmentation is a hierarchical structure which allows for the identification of primitives in pie and bar charts. The algorithm was tested on a database composed of charts from business documents. Results are very promising.

    The present work applies similarity theory to the plasma emanating from transferred arc, gas-vortex stabilized plasma cutting torches, to analyze the existing correlation between the arc temperature and the physical parameters of such torches. It has been found that the enthalpy number significantly influence the temperature of the electric arc. The obtained correlation shows an average deviation of 3% from the temperature data points. Such correlation can be used, for instance, to predict changes in the peak value of the arc temperature at the nozzle exit of a geometrically similar cutting torch due to changes in its operation parameters.

    Full Text Available Cutting temperature is very important parameter of cutting process. Around 90% of heat generated during cutting process is then away by sawdust, and the rest is transferred to the tool and workpiece. In this research cutting temperature was measured with artificial thermocouples and question of investigation of metal machinability from aspect of cutting temperature was analyzed. For investigation of material machinability during turning artificial thermocouple was placed just below the cutting top of insert, and for drilling thermocouples were placed through screw holes on the face surface. In this way was obtained simple, reliable, economic and accurate method for investigation of cutting machinability.

    Alam, K; Mitrofanov, A V; Silberschmidt, V V; Baeker, M

    2009-01-01

    Bone cutting is a frequently used procedure in the orthopaedic surgery. Modern cutting techniques, such as ultrasonic assisted drilling, enable surgeons to perform precision operations in facial and spinal surgeries. Advanced understanding of the mechanics of bone cutting assisted by ultrasonic vibration is required to minimise bone fractures and to optimise the technique performance. The paper presents results of finite element simulations on ultrasonic and conventional bone cutting analysing the effects of ultrasonic vibration on cutting forces and stress distribution. The developed model is used to study the effects of cutting and vibration parameters (e.g. amplitude and frequency) on the stress distributions in the cutting region.

    Burnable poison rods attached to spent fuels are contained in a containing box and transported to a receiving pool. The burnable poison rod-containing box is provisionally situated by the operation to a handling device to a provisional setting rack in a cutting pool and attached to a cutting guide of a cutting device upon cutting. The burnable poison rod is cut only in a cutting pool water and tritium generated upon cutting is dissolved into the cutting pool water. Diffusion of tritium is thus restricted. Further, the cutting pool is isolated by a partition device from the receiving pool during cutting of the burnable poison rod. Accordingly, water in which tritium is dissolved is inhibited from moving to the receiving pool and prevail of tritium contamination can be avoided. (T.M.)

    Full Text Available This article offers an appraisal of the social ministry of Pentecostal churches through fellowship, healing and livelihood creation in the township communities of the city of Tshwane. In meeting this aim the discussion advances a thesis of these churches as agents of social support and survival of the downcast. In particular, the article attempts to show how these churches exert themselves towards establishing not only moral responsibility, but also a context where the weakest and the least privileged can learn how to survive. The squatter camp people are unique with the special challenges requiring distinctive consideration. Pentecostal churches believe that the lost people matter to God and are of importance to their congregations as well. The backyard Bible study ministries and mutual cooperation strategies are employed for mutual support. Making use of the existing empirical research data and available literature will show how Pentecostal churches in the townships support the laity and community in times of need.

    Adel, M.

    2008-12-01

    Beginning in late 2001, the Afghanistan government started developing plans for the revitalization of the Natural Resources sector. This revitalization included the rebuilding and reorganization of the capabilities of the Ministry of Mines and Industries (now the Ministry of Mines) and the Afghan Geological Survey and several other Afghan ministries. The initial focus was on the development of new mining and hydrocarbon laws, which were supported by the World Bank. Concurrent with these activities was the recognized need to identify, organize and compile existing data and information on the natural resources of the country. This has been followed by the use of these data and information to provide preliminary assessments of the oil and gas resources, mineral resources, water resources, coal resources, and earthquake hazards, all based on existing data. A large part of these assessment efforts required the development of a geospatial infrastructure through the use of satellite imagery and other remote sensing technologies. Institutional and capacity building were integral parts of all efforts. With the assessment and law activities ongoing, the Ministry of Mine has now turned to the development of a leasing framework, which address the critical need of transparency of leasing, lease management, and royalty collection. This new leasing system was implemented in spring 2008 with the leasing of the Aynak Copper Deposit, which is located about 25 miles south of Kabul. At the moment, a second world class mineral deposit is being considered for leasing within the next year. Oil and gas lease tracts are also under development in the northern oil and gas basins of Afghanistan. With the support of the Afghan government, the U.S. Geological Survey (USGS) has recently completed the gathering of new data and information in support of the Natural Resources Sector. These data gathering missions include gravity, magnetics, radar, and hyperspectral data, which were gathered through

    Problems related to the use of personal protective equipment (PPE), specially the use of protective gloves for the manual sugar cane cutting, motivated this research, made possible by a tripartite negotiation involving the Ministry of Labor, the Union of Rural Workers and the Employer's Association of sugarcane agribusiness. The main objective was to evaluate, from an ergonomics perspective, the impact of use of the gloves during the manual cane sugar cutting, raising questions on safety, effectiveness and comfort. The research was carried in a sugarcane industry of São Paulo for two seasons involving 47 workers who made a qualitative analysis of acceptance of four models of protective gloves. The methodology included the use of semi-structured interviews, questionnaires and field observations and the experimental determination of the coefficient of static friction developed between the gloves and the surfaces of the machete handle. The main results indicate the general inadequacy of the gloves currently used forcing the employees to improvise. Workers found the glove of leather and nylon scraping the best reported for comfort in use. The overall results highlight the problem of detachment of test standards for the manufacture of PPE, ignoring users and the activity to be performed.

  8. Administrative reform in the Venezuelan Ministry of Education: A case analysis of the 1970's

    1984-06-01

    Democracy arrived in Venezuela in 1958, and reforming the rigid, centralized and unrepresentative institutions of government subsequently assumed a high priority. This article, based on data gathered in Venezuela several times over a twelve-year period by means of a standard field research methodology, represents a longitudinal case study of efforts through the 70's to generate administrative reform in the Ministry of Education. Specifically, the reform proposed to decentralize and regionalize the organization and management of education in order to promote regional socio-economic development. The study describes and discusses political and organizational factors which disrupted and frustrated the reform process, including: (1) lack of political continuity and maturity; (2) lack of appropriate structures within the system and of real desire on the part of ministry officials to initiate an effective delegation of powers and responsibilities; (3) lack of adequate mechanisms for gathering, processing and distributing information; and (4) lack of sufficient personnel within the ministry with the training and sustained experience to manage complex programs. As in many other countries, the ideals of the reform in Venezuela outstripped the political and human realities of the situation there. Comparative research is now needed to enable other nations to learn from this experience.

    2000-07-24

    The Ministry of Atomic Energy of the Russian Federation (Minatom) is one of Russia's largest and most influential federal bodies. Throughout 1999 its head, Yevgeny Adamov, has worked to increase the Ministry's commercial competitiveness by consolidating redundant facilities and tightening control over subsidiary organizations. Economic difficulties and budget constraints, however, have hindered Minatom's ability to achieve many of its programs and goals. As a result, the Ministry has continued, renewed or initiated contracts with several countries possessing questionable commitments to nonproliferation and has sought to expand its role in international nuclear waste management and spent fuel reprocessing in order to raise new sources of revenue. While many of these programs are not likely to come to fruition, others raise significant nonproliferation and environmental concerns. This paper reviews select programs driving Minatom's efforts to raise funds, comments on their potential viability, and highlights areas likely to be of particular concern for the United States over the next three to five years.

    Full Text Available The identification of commercial circuits in the Machala canton contributes to the economic and social development of the members of the San José de Guartiguro agricultural cooperative located in the Guanazón parish of Zaruma canton. The purpose of this paper was to identify commercial circuits for the marketing of baskets of organic agricultural products in nine Public Ministries of Machala. An inquiry was carried out among 138 workers, and the distribution process of the baskets was observed. The program Microsoft Excel 2013was applied to organize data in tables and graphics. Results showed that 84.14% of the workers inquired agreed to purchase the baskets at the Ministries. The implementation of commercial circuits in Machala canton that will favor the access of the members of the agricultural cooperative to institutional markets is proposed. This measure will also enable the workers at the Ministries to acquire organic agricultural products at lower prices in their work place.

    2017-01-01

    Full Text Available Religiosity has a profound role and influence on youth development within a community. Religiosity promotes risk reduction and positive moral characteristics and thus remains an avenue of opportunity for transformation in considering the lived experiences of vulnerable young people living on the Cape Flats in the Western Cape, South Africa. The Cape Flats is an area that is overwhelmed with unemployment, poverty, gang violence, chemical substance abuse and a general societal abandonment of young people. It is out of dire hopelessness that a meaningful relationship with God can be experienced by youth. The Cape Flats is, therefore, a fertile space for an intervention of religiosity. This article will research how the agency of youth ministry as a positive youth development can assist in youth development within a community in tension like that of the Cape Flats. While youth development is a broad category for consideration and research, this article will primarily focus on identity formation of young people, in particular, the vulnerable youth living on the Cape Flats.Intradisciplinary and/or interdisciplinary implications: The agency of youth ministry, in an evangelical epistemology, should seek to address the influencers on adolescent identity formation, as one�s identity has a direct bearing on faith formation. The potential outcome of the article would allow the youth ministry to take serious the impact of the lived realities of youth and adjust their programmatic designs and outcomes, in relation to youth faith formation.

    The Botswana's Ministry of Health redesigned and adopted a new organizational structure in 2005, which was poorly implemented. This article explores factors that influenced the implementation of this organizational structure. This article draws from data collected through in-depth interviews with 54 purposively selected key informants comprising policy makers, senior managers and staff of the Ministry of Health (N = 40) and senior officers from various stakeholder organizations (N = 14). Participants generally felt that the review of the Ministry of Health organizational structure was important. The previous structure was considered obsolete with fragmented functions that limited the overall performance of the health system. The new organizational structure was viewed to be aligned to current national priorities with potential to positively influence performance. Some key weaknesses identified included lack of consultation and information sharing with workers during the restructuring process, which affected the understanding of their new roles, failure to mobilize key resources to support implementation of the new structure and inadequate monitoring of the implementation process. Redesigning an organizational structure is a major change. There is a need for effective and sustained leadership to plan, direct, coordinate, monitor and evaluate the implementation phase of the reform. Copyright © 2014 John Wiley & Sons, Ltd.

    2008-10-01

    In some applications, laser cutting of wedge surfaces cannot be avoided in sheet metal processing and the quality of the end product defines the applicability of the laser-cutting process in such situations. In the present study, CO 2 laser cutting of the wedge surfaces as well as normal surfaces (normal to laser beam axis) is considered and the end product quality is assessed using the international standards for thermal cutting. The cut surfaces are examined by the optical microscopy and geometric features of the cut edges such as out of flatness and dross height are measured from the micrographs. A neural network is introduced to classify the striation patterns of the cut surfaces. It is found that the dross height and out of flatness are influenced significantly by the laser output power, particularly for wedge-cutting situation. Moreover, the cut quality improves at certain value of the laser power intensity.

    Recent economic growth in Kazakhstan has been accompanied by slower improvements in population health and this has renewed impetus for health system reform. Strengthening strategic planning and policy-making capacity in the Ministry of Health has been identified as an important priority, particularly as the Ministry of Health is leading the health system reform process. The intervention was informed by the United Nations Development Programme (UNDP) framework for capacity building which views capacity building as an ongoing process embedded in local institutions and practices. In response to local needs extra elements were included in the framework to tailor the capacity building programme according to the existing policy and budget cycles and respective competence requirements, and link it with transparent career development structures of the Ministry of Health. This aspect of the programme was informed by the institutional capability assessment model used by the United Kingdom National Health Service (NHS) which was adapted to examine the specific organizational and individual competences of the Ministry of Health in Kazakhstan. There were clear successes in building capacity for policy making and strategic planning within the Ministry of Health in Kazakhstan, including better planned, more timely and in-depth responses to policy assignments. Embedding career development as a part of this process was more challenging. This case study highlights the importance of strong political will and high level support for capacity building in ensuring the sustainability of programmes. It also shows that capacity-building programmes need to ensure full engagement with all local stakeholders, or where this is not possible, programmes need to be targeted narrowly to those stakeholders who will benefit most, for the greatest impact to be achieved. In sum, high quality tailor-made capacity development programmes should be based on thorough needs assessment of individual and

    A model is presented for calculating Reggeon-Pomeranchukon cuts, making use explicitly of the Mandelstam diagram. External spins are treated in a natural way. Calculation for the general case is outlined and it is shown that in practical application the cut can be calculated in a standard way. Cuts associated with the exchanges of π, rho, B, and A 2 are considered, and characteristics of the RP cuts, as well as the structure functions, are extracted and discussed. It is found that the model differs considerably from the absorption model. Two suppression schemes are operative which control the magnitudes of cut contributions to amplitudes with ''naturality'' opposite to the Reggeon. The πP cut is found to be a unique case because of the smallness of the pion mass. In general, the RP cuts are self-conspiratorial. At very high energies, all cuts, except πP cut, exhibit quasifactorization

    In is desirable to use remote underwater device for the decommissioning work of highly radioactive components such as the nuclear internals from a view point of reducing the ranitidine exposure to the worker. Underwater laser cutting technology has advantages. First advantage in underwater laser cutting technology is that low reaction force during cutting, namely, remote operability is superior. Second point is that underwater laser cutting generates a little amount of secondary waste, because cutting kerf size is very small. Third point is that underwater laser cutting has low risk of the process delay, because device trouble is hard to happen. While underwater laser cutting has many advantages, the careful consideration in the safe treatment of the offgas which underwater laser cutting generates is necessary. This paper describes outline of underwater laser cutting technology developed by IHI Corporation (IHI) and that this technology is effective in various dismantling works in water. (author)

    In this paper the morphology of the laser cut front generated by fibre lasers was investigated by observation of the 'frozen' cut front, additionally high speed imaging (HSI) was employed to study the fluid dynamics on the cut front while cutting. During laser cutting the morphology and flow properties of the melt film on the cut front affect cut quality parameters such as cut edge roughness and dross (residual melt attached to the bottom of the cut edge). HSI observation of melt flow down a laser cutting front using standard cutting parameters is experimentally problematic because the cut front is narrow and surrounded by the kerf walls. To compensate for this, artificial parameters are usually chosen to obtain wide cut fronts which are unrepresentative of the actual industrial process. This paper presents a new experimental cutting geometry which permits HSI of the laser cut front using standard, commercial parameters. These results suggest that the cut front produced when cutting medium section (10 mm thick) stainless steel with a fibre laser and a nitrogen assist gas is covered in humps which themselves are covered by a thin layer of liquid. HSI observation and theoretical analysis reveal that under these conditions the humps move down the cut front at an average speed of approximately 0.4 m/s while the covering liquid flows at an average speed of approximately 1.1 m/s, with an average melt depth at the bottom of the cut zone of approximately 0.17 mm.

    Laser cutting technique produces narrow, precise, fast, and repeatable cuts in thin nickel-allow bellows material. Laser cutting operation uses intense focused beam to melt material and assisting gas to force melted material through part thickness, creating void. When part rotated or moved longitudinally, melting and material removal continuous and creates narrow, fast, precise, and repeatable cut. Technique used to produce cuts of specified depths less than material thickness. Avoids distortion, dents, and nicks produced in delicate materials during lathe trimming operations, which require high cutting-tool pressure and holding-fixture forces.

    significant lensing effect for one of the galaxy clusters in the field ( CL0053-37 , see PR Photo 18d/02 ); the images of background galaxies around this cluster were noticeably distorted in the direction tangential to the cluster center. Based on the measured degree of distortion, a map of the distribution of (dark) matter in this direction was constructed ( PR Photo 18e/02 ). The separation of unlensed foreground (bluer) and lensed background galaxies (redder) greatly profited from the photometric measurements done by Gieren's group in the course of their work on the Cepheids in NGC 300. Assuming that the lensed background galaxies lie at a mean redshift of 1.0, i.e. a distance of 8 billion light-years, a mass of about 2 x 10 14 solar masses was obtained for the CL0053-37 cluster. This lensing analysis in the NGC 300 field is part of the Garching-Bonn Deep Survey (GaBoDS) , a weak gravitational lensing survey led by Peter Schneider (IAEF). GaBoDS is based on exposures made with the WFI and until now a sky area of more than 12 square degrees has been imaged during very good seeing conditions. Once complete, this investigation will allow more insight into the distribution and cosmological evolution of galaxy cluster masses, which in turn provide very useful information about the structure and history of the Universe.

    2010-01-01

    The properties of null geodesic congruences (NGCs) in Lorentzian manifolds are a topic of considerable importance. More specifically NGCs with the special property of being shear-free or asymptotically shear-free (as either infinity or a horizon is approached) have received a great deal of recent attention for a variety of reasons. Such congruences are most easily studied via solutions to what has been referred to as the 'good cut equation' or the 'generalization good cut equation'. It is the purpose of this paper to study these equations and show their relationship to each other. In particular we show how they all have a four-complex-dimensional manifold (known as H-space, or in a special case as complex Minkowski space) as a solution space.

    1993-09-01

    A variable incident angle, asymmetric cut, double crystal monochromator was tested for use on beamlines at the Advanced Photon Source (APS). For both undulator and wiggler beams the monochromator can expand area of footprint of beam on surface of the crystals to 50 times the area of incident beam; this will reduce the slope errors by a factor of 2500. The asymmetric cut allows one to increase the acceptance angle for incident radiation and obtain a better match to the opening angle of the incident beam. This can increase intensity of the diffracted beam by a factor of 2 to 5 and can make the beam more monochromatic, as well. The monochromator consists of two matched, asymmetric cut (18 degrees), silicon crystals mounted so that they can be rotated about three independent axes. Rotation around the first axis controls the Bragg angle. The second rotation axis is perpendicular to the diffraction planes and controls the increase of the area of the footprint of the beam on the crystal surface. Rotation around the third axis controls the angle between the surface of the crystal and the wider, horizontal axis for the beam and can make the footprint a rectangle with a minimum. length for this area. The asymmetric cut is 18 degrees for the matched pair of crystals, which allows one to expand the footprint area by a factor of 50 for Bragg angles up to 19.15 degrees (6 keV for Si[111] planes). This monochromator, with proper cooling, will be useful for analyzing the high intensity x-ray beams produced by both undulators and wigglers at the APS

    Oil, Gas and Energy sector has been identified as an essential driving force in the Malaysian Economic Transformation Programs (ETP). Recently confirmed discovery of many offshore oil and gas deposits in Malaysian waters has ignited new confidence in this sector. However, this has also spurred intense interest on safeguarding the health and environment of coastal waters in Malaysia from adverse impact resulting from offshore oil and gas production operation. Offshore discharge of spent drilling mud and rock cuttings is the least expensive and simplest option to dispose of large volumes of drilling wastes. But this onsite offshore disposal may have adverse environmental impacts on the water column and the seabed. It may also pose occupational health hazards to the workers living in the offshore platforms. It is therefore important to model the transport and deposition of drilling mud and rock cuttings in the sea to enable proper assessment of their adverse impacts on the environment and the workers. Further, accumulation of drill particles on the seabed may impede proper operation of pipelines on the seabed. In this paper, we present an in-house application model TUNA-PT developed to cater to local oil and gas industry needs to simulate the dispersion and mount formation of drill cuttings by offshore oil and gas exploration and production platforms. Using available data on Malaysian coastal waters, simulation analyses project a pile formation on the seabed with a maximum height of about 1 m and pile radius of around 30 to 50 m. Simulated pile heights are not sensitive to the heights of release of the cuttings as the sensitivity has been mitigated by the depth of water.

The purpose of this study was to improve nutritional status among under-nourished children in poor families. Methods: A total of 50,000 children under 5 (girls and boys) in 30 provinces in Iran which suffered by moderate and severe malnutrition participated (<-2SD weight for age) in this program. Malnourished children belong to poor families were determined; weights and heights were measured and anthropometric indicators were determined based on WHO, 2007. Then, these malnourished children were introduced to Imam Khomeini Foundation. Khomeini Foundation as one of the biggest NGO in Iran which supports poor families since 1979. This study collaborated with Ministry of Welfare, Ministry of Health and Emam Khomeini. They have started to receive monthly supportive food basket which could support their daily nutritional requirements. This basket included (meat, egg, cheese, legumes, milk, tuna fish, chicken, liquid oil). Along with food support community health workers were actively involved with counseling of mothers on the nutritional requirements of children. Nutritional support cut for whoever has been improved nutritional status. However, nutritional education still had continued. Results: The results of monitoring & evaluation (according to anthropometric indicators) of this plan have shown around more than 45% of children that received food basket had consistently improved nutritional status. Conclusion: Likewise other intervention nutrition programs in developing countries this project showed that inter sector collaboration have been the best way for decreasing malnutrition in children.

    An abrasive suspension jet (ASJ) formed by propelling abrasive suspension through a nozzle has a greater cutting capability than the conventional abrasive water jet. However the cutting capability of submerged ASJs decreases drastically with increasing the standoff distance and the pressure around the jet. A sheathed nozzle with ventilation for ASJs has been developed as a mean of extending the effective stand-off distance and improving the cutting capabilities under submerged condition. In the present investigation, cutting tests by ASJs in air and under submerged condition are conducted with specimens of aluminum alloy. Air coated ASJs are formed by using a sheathed nozzle with ventilation. The relative cutting depth is defined as the cutting depth under submerged condition divided by the cutting depth in air at the same standoff distance. The relative cutting depth is arranged effectually by the cavitation number based on the cavity pressure measured at the sheath. (author)

    Purpose: To improve the cutting performance to a level as comparable with that in air, as well as prevent the scattering of the radioactive materials upon cutting to the level as that in water cutting. Method: After igniting a gas cutting torch automatically, water spray by the local water sprayer is started by the actuation of a submerged pump, while a gas cutting manipulator is operated to cut the nuclear reactor pressure vessel. In this way, cutting exhaust gases resulted from the gas cutting torch are water-washed by the spray from the local water sprayer and falls within the nuclear rector pressure vessel in the form of water streams or droplets along the inner wall surface of the pressure vessel. Further, water is fed again to the local water sprayer by the submerged pump. (Kawakami, Y.)

    2000-07-24

    This paper reviews select programs driving the Ministry of Atomic Energy of the Russian Federation's (Minatom) efforts to raise funds, comments on their potential viability, and highlights areas likely to be of particular concern for the US over the next three to five years. The paper's findings are: (1) Despite numerous cabinet displacements throughout the Yeltsin administration, Yevgeny Adamov was reappointed Minister on four occasions. With Boris Yeltsin's January 1, 2000 resignation, Adamov's long-term position as the head of the Ministry is more tenuous, but he will likely retain his position until at least the March 2000 elections. Acting President Vladimir Putin is unlikely to reorganize his cabinet prior to that date and there are no signs that Putin is dissatisfied with Adamov's leadership of Minatom. (2) Adamov's chief priorities are downsizing Minatom's defense sector, increasing the oversight of subsidiary bodies by the central bureaucracy and consolidating commercial elements of the Ministry within an umbrella organization called Atomprom. (3) Viktor Mikhaylov, Adamov's predecessor and critic of his reform efforts, has been relieved of his duties as First Deputy Minister. While he retains his positions as Chief of the Science Councils and Chief Scientist at Arzamas-16, his influence on Minatom's direction is greatly diminished. Adamov will likely continue his efforts to further marginalize Mikhaylov in the coming year. (4) Securing extra-budgetary sources of income continues to be the major factor guiding Minatom's international business dealings. The Ministry will continue to aggressively promote the sale of nuclear technology abroad, often to countries with questionable nonproliferation commitments. (5) Given the financial difficulties in Russia and Minatom's client states, however, few nuclear development programs will come to fruition for a number of years, if ever. Nevertheless, certain

  8. Study of Cutting Edge Temperature and Cutting Force of End Mill Tool in High Speed Machining

    Directory of Open Access Journals (Sweden)

    Kiprawi Mohammad Ashaari

    2017-01-01

    Full Text Available A wear of cutting tools during machining process is unavoidable due to the presence of frictional forces during removing process of unwanted material of workpiece. It is unavoidable but can be controlled at slower rate if the cutting speed is fixed at certain point in order to achieve optimum cutting conditions. The wear of cutting tools is closely related with the thermal deformations that occurred between the frictional contact point of cutting edge of cutting tool and workpiece. This research paper is focused on determinations of relationship among cutting temperature, cutting speed, cutting forces and radial depth of cutting parameters. The cutting temperature is determined by using the Indium Arsenide (InAs and Indium Antimonide (InSb photocells to measure infrared radiation that are emitted from cutting tools and cutting forces is determined by using dynamometer. The high speed machining process is done by end milling the outer surface of carbon steel. The signal from the photocell is digitally visualized in the digital oscilloscope. Based on the results, the cutting temperature increased as the radial depth and cutting speed increased. The cutting forces increased when radial depth increased but decreased when cutting speed is increased. The setup for calibration and discussion of the experiment will be explained in this paper.

  9. Optical Cutting Interruption Sensor for Fiber Lasers

    Directory of Open Access Journals (Sweden)

    Benedikt Adelmann

    2015-09-01

    Full Text Available We report on an optical sensor system attached to a 4 kW fiber laser cutting machine to detect cutting interruptions. The sensor records the thermal radiation from the process zone with a modified ring mirror and optical filter arrangement, which is placed between the cutting head and the collimator. The process radiation is sensed by a Si and InGaAs diode combination with the detected signals being digitalized with 20 kHz. To demonstrate the function of the sensor, signals arising during fusion cutting of 1 mm stainless steel and mild steel with and without cutting interruptions are evaluated and typical signatures derived. In the recorded signals the piercing process, the laser switch on and switch off point and waiting period are clearly resolved. To identify the cutting interruption, the signals of both Si and InGaAs diodes are high pass filtered and the signal fluctuation ranges being subsequently calculated. Introducing a correction factor, we identify that only in case of a cutting interruption the fluctuation range of the Si diode exceeds the InGaAs diode. This characteristic signature was successfully used to detect 80 cutting interruptions of 83 incomplete cuts (alpha error 3.6% and system recorded no cutting interruption from 110 faultless cuts (beta error of 0. This particularly high detection rate in combination with the easy integration of the sensor, highlight its potential for cutting interruption detection in industrial applications.

    The proactive search of deaths is a strategy for capturing events that were not informed to the Mortality Information System of Ministry of Health. Its importance to reduce underreporting of deaths and to evaluate the operation of the information system is widely known. To describe the methodology and main findings of the Proactive Search of Deaths, 2013, establishing the contribution of different information sources. The research was carried out in 79 Brazilian municipalities. We investigated several official and unofficial sources of information about deaths of municipality residents. Every information source investigated and all cases found in each source were typed in an on-line panel. The second stage of the research was the confirmation of cases to verify information of year and residence and to complete missing information. For all confirmed cases, we estimated the completeness of death registration and correction factors according to the adequacy level of mortality information. We found 2,265 deaths that were not informed to the Mortality Information System. From those, 49.3% were found in unofficial sources, cemeteries and funeral homes. In some rural municipalities, precarious burial conditions were found in cemeteries in the middle of the forest and no registration of the deceased. Correction factors were inversely associated to the adequacy level of mortality information. The findings confirm the association between level of information adequacy and completeness of death registration, and indicate that the application of the proactive search is an effective method to capture deaths not informed to the Ministry of Health.

    Full Text Available Deconcentration policies held because not all authority/government affairs can be done by using the principle of decentralization. The intent of this policy is to synergize the central and local relations. However, in reality not all of the activities of these policies can produce output in accordance with the plans and policy objectives, including those carried out by the Ministry of the Interior. Such conditions occur because of the policy implementation process has not been going well. This study uses naturalistic methods or qualitative descriptive explanation. The purpose of this study is to investigate the process of policy implementation, identify the factors that influence, as well as the results of policy implementation devolution of government affairs deconcentration scope of the Ministry of the Interior in the province of West Java. The results of this study indicate that in general the result of the implementation of deconcentration policy in West Java province is relatively accordance with the objectives of the implementation of deconcentration policy. Similarly, the output of the implementation of deconcentration program targets as predetermined. Nevertheless, there are still many shortcomings in the implementation process.

    To describe the technical aspects of the Exceptional Circumstance Drug Dispensing Program of the Brazilian Ministry of Health, especially with respect to the cost of dispensed medication. Technical information was obtained from the ordinances that regulate the Program. Expenditure from 2000 to 2007 was obtained from the Sistema Único de Saúde's (Unified Healthcare System) Outpatient Information System. All drugs dispensed between 1993 and 2009 and the amount and cost of each procedure were evaluated, based on information from the high-complexity procedure authorization of each of the country's states. The Program changed with the increase in the number of pharmacological agents and presentations distributed by, and the number of diseases contemplated in the program. In 1993, the program distributed 15 pharmacological agents in 31 distinct presentations. This number increased to 109 agents in 243 presentations in 2009. Total Ministry of Health expenditure with medications was R$1,410,181,600.74 in 2007, almost twice the amount spent in 2000, R$684,975,404.43. Diseases whose expenditure increased in the period included chronic renal insufficiency, transplantation, and hepatitis C. The Exceptional Circumstance Drug Dispensing Program is in constant transformation, aimed at building instruments and strategies that can ensure and expand access to medication among the population. Alternatives should be sought to decrease the financial impact of the Program to a level that does not impact other sectors of the health care system, given the high cost associated with novel interventions.

  15. Imagine-making disciples in youth ministry … that will make disciples

    Full Text Available Discipling youth may be one of the ‘missing links’ in developing missional thinking and missional local churches. This is even more so where churches suffer from a very obvious estrangement among generations. This article draws on the most recent literature on developing missional churches. The departure point is the argument of a the New Testament scholar, who refers to the description of Matthew 28:16–20 as the manifesto of the church – a manifesto that lies on the same level of value as the Shema of Israel: ‘Listen, o Israel, the Lord our God is the only One.‘ This manifesto wants to tell us how new and differently we have to think on how people come into the body and how people will stay in the body. Picking up on three of my theological premises this article will work with a research question: What kind of church will make disciples in youth ministry? It will also work towards theological suggestions on how to make disciples in youth ministry in such a way that young disciples will make disciples.

    2014-06-01

    After having recalled some important results of the fifth IPCC report, this report aims at providing a mapping of biases by which climate disruption impacts the different activities, functions, and missions of the French Ministry of Defence. This disruption results in new risks and threats, but could also be the background of new legal and administrative standards and constraints which may affect military capacities. The authors first study how climate disruption is addressed by American and British allies, analyse direct and indirect risks and threats which are created or strengthened by climate disruption, identify the impact of climate disruption on operational capacities as a whole, at the industrial level (in product elaboration), and also in the use of hardware on locations which could be modified under the action of climate change. They also propose crisis scenarios on the near and on the long term, in relationship with climate disruption but also with other issues. They state a set of operational recommendations for the Ministry for a better anticipation of impact on the short, medium and long term

  17. Cutting costs without drawing blood.

    Copeland, T

    2000-01-01

    When looking for ways to cut costs, most managers reach for the head-count hatchet, and the markets usually roar with approval. But a company can almost always create far more sustainable value by rigorously evaluating the small-ticket capital items that often get rubber-stamped. Drawing on his experience as a consultant and providing numerous anecdotes, the author contends that those "little" requests often prove to be gold plated or unnecessary. A disciplined evaluation involves asking only eight questions and conducting postmortems--regular audits of units' capital spending. But the payoff is enormous. Because cutting the capital budget increases cash flow, the author argues that a permanent cut of just 15% in the planned level of capital spending could boost some companies' market capitalization by as much as 30%. The first three questions--Is this your investment to make? Does it really have to be new? How are our competitors meeting compliance needs?--are asked of operating managers as they assemble capital project requests. The next three are asked by senior managers of themselves and their colleagues as they examine proposals: Is the left hand duplicating investments made by the right? Are trade-offs between profit and capital spending well understood? Are there signs of budget massage? At the end of the review process, senior managers ask: Are we fully using shared assets? How fine-grained are our capacity measures? The author's suggestions for the postmortem include searching for systematic problems with whole classes of expenditures and making sure audit teams come up with specific recommendations for change.

    A cutting machine includes a gun barrel for receiving a projectile. A compression tube is disposed in flow communication with the barrel and includes a piston therein. A reservoir is disposed in flow communication with the tube and receives a first gas under pressure. A second gas fills the compression tube on a front face of the piston. And, the pressurized first gas is discharged into the tube on a back face of the piston to accelerate the piston through the tube for compressing the second gas, and in turn launching the projectile through the barrel to impact a workpiece.

    2012-01-01

    Proponents of Lean Philosophy believe that successful businesses must reduce waste in working time and resources to a minimum, and maximise their use in productive work. The productive work of the Acute Medical Unit is to provide effective clinical management to a daily cohort of acutely ill patients. Many Clinicians are cynical about Lean. In this article, Dr Caldwell discusses how many clinicians complain of too much crap in the workplace, which gets in the way of swift, safe high quality clinical care. He argues that "Cutting the Crap" in the Acute Medical Unit is entirely consistent with Lean approaches to management of complex systems.

    Fuchs, A. N.; Schoeberl, M.; Tremmer, J.; Zaeh, M. F.

    Due to their high weight-specific mechanical stiffness and strength, parts made from carbon fiber reinforced polymers (CFRP) are increasingly used as structural components in the aircraft and automotive industry. However, the cutting of preforms, as with most automated manufacturing processes for CFRP components, has not yet been fully optimized. This paper discusses laser cutting, an alternative method to the mechanical cutting of preforms. Experiments with remote laser cutting and gas assisted laser cutting were carried out in order to identify achievable machining speeds. The advantages of the two different processes as well as their fitness for use in mass production are discussed.

    Computer-controlled machine-tool system uses laser beam assisted by directed flow of air to cut refractory materials into complex three-dimensional shapes. Velocity, position, and angle of cut varied. In original application, materials in question were thermally insulating thick blankets and tiles used on space shuttle. System shapes tile to concave or convex contours and cuts beveled edges on blanket, without cutting through outer layer of quartz fabric part of blanket. For safety, system entirely enclosed to prevent escape of laser energy. No dust generated during cutting operation - all material vaporized; larger solid chips dislodged from workpiece easily removed later.

In order to maximize the propagation of cuts, we evaluated the concentrations of auxin (indolbutiric acid and the presence of leaves on the rooting in cuts of Ixora coccinea L. The experiment was conducted in randomized block design, in factorial design 3x4, with three types of cuts (without leaf, with two or four leaves, four concentrations of indolbutiric acid (0, 1000, 2000 and 4000 mg L-1, with four replications and 10 cuts in each experimental unit. After 53 days of implantation the experiment, evaluated the survival(%, rooting(%, sprouting(%, formation of callus(%, number, length and biomass of roots formed. The interaction of the type of cuts with concentrations of auxin was not significant for any of the variables analyzed. The survival of cuttings was not influenced by the treatments. Cuts with two or four leaves presented rooting and length of roots above the cuttings without leaves. The application of auxin does not substitute the presence of leaf in cuts of ixora in vegetative propagation. The vegetative propagation by cut of ixora can be made without application of auxin, and the leaves must be maintained in the cuttings.

    1996-01-01

    A control rod transferred under water in a vertically suspended state is postured horizontally at such a water depth that radiations can be shielded, and then it is cut to a dropping speed limiting portion and a cross-like main body. The separated cross-like main body portion is further cut in the longitudinal direction and separated into a pair of cut pieces each having an L-shaped cross section. A disk like metal saw is used as a cutting tool. Alternatively, a plasma jet cutter or a melting-type water jet cutter is used as a cutting tool. Then, since the spent control rod to be cut is postured horizontally under water, the water depth for the cutting position can be reduced. As a result, the cutting state using the cutting tool can be observed by naked eyes from the position above the water surface thereby enabling to perform the cutting operation reliably. (N.H.)

    2014-01-01

    Phosphorene, a recently fabricated two-dimensional puckered honeycomb structure of phosphorus, showed promising properties for applications in nano-electronics. In this work, we report a chemical scissors effect on phosphorene, using first-principles method. It was found that chemical species, such as H, OH, F, and Cl, can act as scissors to cut phosphorene. Phosphorus nanochains and nanoribbons can be obtained. The scissors effect results from the strong bonding between the chemical species and phosphorus atoms. Other species such as O, S and Se fail to cut phosphorene nanostructures due to their weak bonding with phosphorus. The electronic structures of the produced P-chains reveal that the hydrogenated chain is an insulator while the pristine chain is a one-dimensional Dirac material, in which the charge carriers are massless fermions travelling at an effective speed of light ∼8 × 10 5 m s −1 . The obtained zigzag phosphorene nanoribbons show either metallic or semiconducting behaviors, depending on the treatment of the edge phosphorus atoms. (paper)

    1993-01-01

    Timothy Firnstahl owns five successful restaurants in Seattle, but he recently came very close to owning none. In the early 1990s, he found himself, like so many restauranteurs, facing rising costs, inefficient management, and a recession. Confronting financial annihilation, Firnstahl had to act quickly: since he had no peripherals to trim, he cut off the head of his company. Remarkably, it worked. Firnstahl's problem was his new and innovative restaurant, Sharps Fresh Roasting. The heart of the Sharps concept was a unique long-roasting technique that made lean, inexpensive meats taste as juicy and delicious as fattier, expensive cuts. The process also lent itself to faster service and lower labor costs. But it wasn't working. Sharps wasn't breaking even, and his other restaurants couldn't make up the difference. He needed a solution fast. Firnstahl got his answer from Mikhail Gorbachev: slash the centralized command and liberate the company. In doing so, he would also transfer virtually all power and responsibility to his line managers. And after five months of intensive study and planning, he accomplished what he set out to do. He fired most of his corporate staff, empowered his restaurant managers with "100% Power and Responsibility," and, finally, undertook a massive promotion campaign. A year later, Sharps Fresh Roasting is the gold mine Firnstahl always believed it could be. He's done away with bureaucracy and turned business around in a down market. All this because his managers are managing themselves.

  8. Pastoral ministry in a missional age: Towards a practical theological understanding of missional pastoral care

    2015-03-01

    Full Text Available This article concerns itself with the development of a missional ecclesiology and the practices that may accept the challenge of conducting pastoral ministry in the context of South African, middleclass congregations adapting to a rapidly changing, post-apartheid environment. Some practical theological perspectives on pastoral counselling are investigated, whilst Narrative Therapy is explored as an emerging theory of deconstruction to enable the facilitating of congregational change towards a missional understanding of church life in local communities. Subsequently, the theological paradigm of missional ecclesiology is investigated before drawing the broad lines of a theory for pastoral ministry within missional ecclesiology.Intradisciplinary and/or interdisciplinary implications: In this article, a missional base theory is proposed for pastoral counselling, consisting of interdisciplinary insights gained from the fields of Missiology, Practical Theology, Narrative Therapy and Cognitive Behaviour Therapy. The implications of this proposal for the development of a missional pastoral theory focus on the following three aspects:� re-establishing pastoral identity: exploring Christ� pastoral development: intentional faith formation� pastoral ministry: enabling Christ-centred lives.In such a missional pastoral theory four practices should be operationalised: first of all, a cognitive approach to increasing knowledge of the biblical narrative is necessary. This provides the hermeneutical skills necessary to enable people to internalise the biblical ethics and character traits ascribed to the Christian life. Secondly, a pastoral theory needs to pay close attention to development of emotional intelligence. Thirdly, this should be done in the context of small groups, where the focus falls on the personality development of members. Finally, missional pastoral theory should also include the acquisition of life coaching skills, where leaders can be

    The issues in imaging are the appropriate use of equipment and optimising the organisation of imaging facilities, through a pooling of medical resources. The Ministry responsible for health has confirmed its desire to increase the number of MRI devices in order to better address patient needs in compliance with best practices, especially in dealing with strokes and cancers. The primary need is to reinforce radiation protection, essentially with regard to children. The steps taken are designed to speed up the replacement of irradiating techniques. According to the SROS-PRS (regional health care organisation scheme - regional health care project), the ARS (regional health agencies) are required to mobilize all resources in order to meet the national objectives for improving access to imaging and reducing disparities in access and efficiency. It is up to the ARS to define the territorial distribution of supply, with appropriate gradation of imaging facilities, in particular to ensure a permanent supply of care. (author)

    Full Text Available African culture(s had assigned inferior roles to women in society. The first Christian missionaries did very little to liberate women from this cultural enslavement. The missionaries's understanding of the leadership roles of women was not very different from that of African culture and its societal organisation. Many churches in Africa had kept to this cultural conservatism and also adopted the missionary theology. However, there are some Christians who accept women into the pastoral ministry, while others consider this move as blasphemous and unbiblical. The role of the church in this conflictual issue is to elaborate a new biblical hermeneutic which would help the church to create a conducive environment where men and women would understand their humanity on an equal basis and participate in God's salvific mission for the world.

    To date, 359 cases of anaplastic large cell lymphoma in women with breast implants (BIA-ALCL) worldwide have been reported out of more than 10 million implanted patients but Health Care Authorities suspect this is a possible underestimation and the limited number of cases makes it difficult to clarify its etiology. The General Directorate of Medical Devices and Pharmaceutical Services of the Italian Ministry of Health (IMoH) has examined and studied the Italian BIA-ALCL cases, and the aim of this study is to report on the knowledge and experience gained on this new emerging disease. An official document has been diffused by the IMoH to all the Italian medical associations, aiming at encouraging all physicians to notify each BIA-ALCL case through the compilation of a specific on-line form. A retrospective study has been performed on the notified BIA-ALCL cases collected in the IMoH's database named DISPOVIGILANCE. Research on DISPOVIGILANCE gives back a list of 22 Italian BIA-ALCL cases. The patients' mean age was 49.6 years (range 30 -71). The average time to the onset of the symptoms was 6.8 years (range 1-22). The average time to the diagnosis was 7.8 years (range 4 -22). The estimated incidence of the Italian BIA-ALCL cases related to 2015 is 2.8 per 100.000 patients. The BIA-ALCL pathogenesis remains unknown. The Italian Ministry of Health, together with scientific associations and other Competent Authorities worldwide, is working on the BIA-ALCL issue to increase awareness and knowledge of this disease by healthcare professionals.

    To identify the availability of some essential drugs (ED) at primary health care units of the Mexican Ministry of Health (SSA), using data from a research work conducted in 1996 and 1997. A random sample of the 18 sanitary jurisdictions of states participating in the Extension of Coverage Program (ECP) was drawn. All primary care units from selected jurisdictions were evaluated through an inspection visit, using a checklist that included 36 ED. In phase I of the analysis, the absolute number and proportion of units without a single item of any of the 36 drugs were calculated. In the units with available drugs, the median of the distribution was also calculated. In phase II, the medians according to the type of health unit and state was obtained. The statistic utilized for the comparison of the medians was the Scheffé test with one way variance analysis. In addition, the drugs were classified according to their therapeutic indication and the medians and proportion of available drugs were calculated. The differences in proportion were evaluated with the statistic chi 2. During the visits, on average, 18 of the 36 drugs included in the list of the study were found in the health units. The availability of antibiotics, antituberculosis drugs, and antimalarial drugs was particularly poor. In contrast, oral rehydration salts, family planning methods and vaccines were usually available. In general, the PAC3 states presented the best availability figures. The Ministry of Health of México will have to develop an enormous effort to overcome the obstacles related to the supply of essential drugs in primary health care units. Otherwise, all other efforts directed to meet the needs of the non-insured population will end up being useless, and enormous amounts of the already scarce resources of the health sector will be wasted since drugs are a vital component of the long chain of health care.

The scope of this study covers the school managers of Primary Schools, Secondary Schools and Professional Technical Schools in the capital, Lefkosa, and the inspectors of the Ministry of Education. Data was collected by questionnaire forms, which were answered by the participants. The forms included the “Environmental Consciousness Survey List”. The data was evaluated by using SPSS. The results of this study revealed the environmental attitude, behaviour and knowledge of school managers and inspectors, according to their gender, age, level of education, job and professional seniorities. A sample of the study covered 71 school managers and inspectors of which 38% were females and 62% were males. The results showed that the environmental consciousness level of the school managers and inspectors was 74%, which could be accepted as average level. No significant differences were determined for the environmental consciousness levels of school managers and inspectors regarding the factors of gender, professional seniorities, membership to any environmental organization, and participation in any environmental project. On the other hand, the results indicated an increase in the environmental consciousness levels when the age and level of education increased. Another important result of this study was that the environmental consciousness level of inspectors is higher than the school managers. School managers and inspectors indicated that the most important environmental problem for the world and TRNC is the misuse of natural resources. According to participants, the most important factor for the prevention of environmental problems is the schools and the most important subject is education.

    This report presents the starting poits, implementations and the results of the Futures Clinique commissioned by the Ministry of the Environment and conducted by Finland Futures Research Centre. The theme for the clinique was 'Radical innovations to constrain the climate change by the year 2050'. The focus was set on the households, since the attention has previously been on the industry and production. The time frame from the present to 2050 was chosen because achieving the goals set by EU's climate policy requires emission cuts of 80% by the year 2050. The carbon footprint of households was examined from the perspectives of energy, traffic, food and water and leisure, entertainment and communications. As desirable goals regarding these aspects the participants studied economic efficiency, sustainability and durability, safety and security, healthinesss and comfortable living. The groups discussed also on converging NBIC technologies (nano, bio, information and cognitive technologies) that could enable these goals. According to the concept of Futures Clinique the work was conducted in groups, in which topics attuned by pre-tasks done by the participants were worked on by the methods of the Futures Wheel and the Futures Table. From each group's working resulted various both technological and socio-cultural radical innovations. (orig.)

  18. New Modelling Strategies For Metal Cutting

    International Nuclear Information System (INIS)

    Rosa, Pedro A. R.; Martins, Paulo A. F.; Atkins, Anthony G.

    2007-01-01

    This paper draws from the 'plasticity and friction only' view of metal cutting to the presentation of new modelling strategies based on the interaction between finite elements and modern ductile fracture mechanics. The overall presentation is supported by specially designed orthogonal metal cutting experiments that were performed on Lead test specimens under laboratory-controlled conditions. Comparisons between theoretical predictions and experimental results comprise a wide range of topics such as material flow, cutting forces and specific cutting pressure. The paper demonstrates that while material flow and chip formation can be successfully modelled by traditional 'plasticity and friction only' analyses, the contribution of the fracture work involved in the formation of new surfaces is essential for obtaining good estimates of cutting forces and of the specific cutting pressure

    2015-01-01

    An abrasive suspension jet (ASJ) formed by propelling abrasive suspension through a nozzle has a greater cutting capability than the conventional abrasive water jet. However the cutting capability of submerged ASJs decreases drastically with increasing the standoff distance and the pressure around the jet. A sheathed nozzle nozzle with ventilation for ASJs has been developed as a mean of extending the effective stand-off distance and improving the cutting capabilities under submerged condition. In the present investigation, cutting tests by ASJs in air and under submerged condition are conducted with specimens of aluminum alloy. Air coated ASJs are formed by using a sheathed nozzle with ventilation.

    Analysis of the laser cut surface morphology remain topical. It is related with the fact that the surface roughness is the main index of the cut quality. The present paper deals with the experimental study of the relatively unstudied type of defects on the laser cut surface, dimples, or craters. According to the measurement results, amount of craters per unit of the laser cut surface area rises as the sheet thickness rises. The crater diameter rises together with the sheet thickness and distance from the upper sheet edge. The obtained data permit concluding that the defects like craters are observed predominantly in the case of thick sheets. The results agree with the hypothesis of crater formation as impact structures resulting from the melt drops getting on the cut channel walls upon separation from the cut front by the gas flow.

    Interest in ceramics as a high speed cutting tool material is based primarily on favorable material properties. As a class of materials, ceramics possess high melting points, excellent hardness and good wear resistance. Unlike most metals, hardness levels in ceramics generally remain high at elevated temperatures which means that cutting tip integrity is relatively unaffected at high cutting speeds. Ceramics are also chemically inert against most workmetals.

    Full Text Available Identification of laser cutting conditions that are insensitive to parameter variations and noise is of great importance. This paper demonstrates the application of Taguchi method for optimization of surface roughness in CO2 laser cutting of stainless steel. The laser cutting experiment was planned and conducted according to the Taguchi’s experimental design using the L27 orthogonal array. Four laser cutting parameters such as laser power, cutting speed, assist gas pressure, and focus position were considered in the experiment. Using the analysis of means and analysis of variance, the significant laser cutting parameters were identified, and subsequently the optimal combination of laser cutting parameter levels was determined. The results showed that the cutting speed is the most significant parameter affecting the surface roughness whereas the influence of the assist gas pressure can be neglected. It was observed, however, that interaction effects have predominant influence over the main effects on the surface roughness.

    Full Text Available The Grand Vizier, who had been responsible to the Sultan for the administration of the country, the security of the subjects, foreign policy and wars up to the 19th century, began to lose prominence as a result of the centrist reforms initiated by Mahmut II. The Sultan appointed the Grand Vizier’s as the Prime Minister and distributed his powers among ministries. The Grand Viziership was rapidly institutionalized in the process of adapting to Europe and its main function became determining the politics. However, Sultan Abdulmecit abolished the practice of prime ministry and appointed Koca Hüsrev Pasha as the Grand Vizier after the death of Mahmut II. In this article, the changes in the institution of Grand Viziership in the first half of the 19th century were investigated. 19. yüzyıla kadar, padişaha karşı ülke yönetiminden, tebaanın güvenliğinden, dış politikadan ve savaşlardan sorumlu olan sadrazam, II. Mahmut’un merkeziyetçi reformları neticesinde yetkileri azalmaya başlamıştır. II. Mahmut, sadrazama bütün vekillerin başı olmak üzere başvekil sanını vererek, yetkilerini nezaretler arasında dağıtmıştır. Avrupa’ya ayak uydurma sürecinde sadrazamlık hızla kurumlaşırken asıl işlevi de siyaseti belirlemek ve uygulamak olmuştur. Lakin II. Mahmut’un ölümünden sonra Sultan Abdülmecit, Koca Hüsrev Paşa’yı sadrazam tayiniyle başvekil unvanı kaldırılarak tekrar sadrazam tabiri kullanılmaya başlanmıştır.

    Evidence-informed health policymaking logically depends on timely access to research evidence. To our knowledge, despite the substantial political and societal pressure to enhance the use of the best available research evidence in public health policy and program decision making, there is no study addressing availability of peer-reviewed research in Canadian health ministries. To assess availability of (1) a purposive sample of high-ranking scientific journals, (2) bibliographic databases, and (3) health library services in the fourteen Canadian health ministries. From May to October 2011, we conducted a cross-sectional survey among librarians employed by Canadian health ministries to collect information relative to availability of scientific journals, bibliographic databases, and health library services. Availability of scientific journals in each ministry was determined using a sample of 48 journals selected from the 2009 Journal Citation Reports (Sciences and Social Sciences Editions). Selection criteria were: relevance for health policy based on scope note information about subject categories and journal popularity based on impact factors. We found that the majority of Canadian health ministries did not have subscription access to key journals and relied heavily on interlibrary loans. Overall, based on a sample of high-ranking scientific journals, availability of journals through interlibrary loans, online and print-only subscriptions was estimated at 63%, 28% and 3%, respectively. Health Canada had a 2.3-fold higher number of journal subscriptions than that of the provincial ministries' average. Most of the organisations provided access to numerous discipline-specific and multidisciplinary databases. Many organisations provided access to the library resources described through library partnerships or consortia. No professionally led health library environment was found in four out of fourteen Canadian health ministries (i.e. Manitoba Health, Northwest

    Comparisons and discussions were made on the plasma cutting and laser cutting in sheet steel cutting, referring partly to gas cutting. Historically, the cutting has been developed from gas, plasma, and laser in that order, and currently these three methods are used mixedly. Generally, the plasma cutting is superior in cutting speed, but inferior in cut face quality, and it requires measures of dust collection. Due to high accuracy and quality in cut face, the laser cutting has been practically used for quite some time in the thin sheet industry, but medium to thick sheet cutting had a problem of unavailability of high output laser suitable for these ranges. However, the recent technologies have overcome the problem as a result of development at the authors {prime} company of a 2 kW class laser cutter capable of cutting 19 mm thick sheet. The cutter has been proven being particularly excellent in controllability. Choice of whether plasma or laser would depend upon which priority is to be taken, cost or accuracy. 15 figs., 3 tabs.

    One of the main objectives of the German Federal Ministry for the Environment, within the overall concept of the Federal Government to help establish democracy and a social market economy in Eastern Europe, is to contribute to improving the safety of nuclear power plants. Safety evaluations of Soviet-type reactors in the former German Democratic Republic have given rise to findings since 1990 which resulted in qualified cooperation especially in Russia and Ukraine. These activities mainly serve to strengthen the role of supervisory authorities in the interest of nuclear safety, and to make available technical inspection systems for nuclear power plants. German experts also conducted safety analyses and radioactivity measurements in situ. The financial expenditure between 1990 and 1995 totaled approx. DM 150 million. The money was spent on some 75 different projects for which contracts were awarded to qualified German firms. All measures, from analyses to the provision of equipment to training seminars, serve the purpose of providing help towards self-help, together with an adequate transfer of know-how. (orig.) [de

    With support from the Korean Ministry of the Environment (ME), our interdisciplinary research staff developed the COnsumer Product Exposure and Risk assessment system (COPER). This system includes various databases and features that enable the calculation of exposure and determination of risk caused by consumer products use. COPER is divided into three tiers: the integrated database layer (IDL), the domain specific service layer (DSSL), and the exposure and risk assessment layer (ERAL). IDL is organized by the form of the raw data (mostly non-aggregated data) and includes four sub-databases: a toxicity profile, an inventory of Korean consumer products, the weight fractions of chemical substances in the consumer products determined by chemical analysis and national representative exposure factors. DSSL provides web-based information services corresponding to each database within IDL. Finally, ERAL enables risk assessors to perform various exposure and risk assessments, including exposure scenario design via either inhalation or dermal contact by using or organizing each database in an intuitive manner. This paper outlines the overall architecture of the system and highlights some of the unique features of COPER based on visual and dynamic rendering engine for exposure assessment model on web.

    In Singapore, the notification of workplace accidents and occupational diseases is a legal requirement under the Workplace Safety and Health (Incident Reporting) Regulations. This review is to identify back injury cases with physical work stresses and propose recommendations for preventive measures. Cases involving back injuries notified to the Ministry of Manpower (MOM) from 1 January 2011 to 31 December 2012 were reviewed. Using predefined criteria, cases with physical work stresses were identified and the associated variables analysed. A total of 1124 notifications involving back injuries were received from 2011 to 2012; 579 cases (52%) were identified to have physical work stresses, of which 447 cases (77%) were males and 375 (64%) of them were between the ages of 21 to 40 years. The commonest physical work stresses were carrying (35%), awkward postures (22%) and lifting (20%). Majority of the cases came from the following sectors: construction (14%), accommodation and food services (12%), transport and storage (12%), manufacturing (10%) and wholesale and retail trade (10%). We identified the main physical work stresses in the back injury cases as carrying, awkward postures and lifting. The common industries involved were construction, accommodation and food services, and transport and storage sectors. This is useful for programmes aimed at reducing physical work stresses which can lead to improved work and health outcomes for our workers.

In the memorandum 26 policy targets are formulated for the period 2004-2008 in the fields of climate and energy, noise, hazardous materials, environmental care, and biological diversity and nature. One of the projects concerns the participation in a wind turbine farm in the Dutch province Drenthe. [Dutch] Uitgangspunt van de nota is een milieuverantwoorde bedrijfsvoering. Na een grondige evaluatie van de Defensie Milieubeleidsnota (DMB) 2000 zijn in de DMB 2004 zo'n 26 doelstellingen geformuleerd tot en met het jaar 2008. De belangrijkste doelstellingen liggen op het gebied van klimaat en energie, geluid, gevaarlijke stoffen, afval, milieuzorg, en biodiversiteit en natuur. Een van de opvallendste projecten uit DMB 2004 is een windturbinepark in Drenthe. Defensie gaat daarbij deelnemen aan een provinciaal project op en naast het magazijnencomplex te Coevorden. Van acht a negen te plaatsen turbines, die elk 2 MegaWatt elektriciteit gaan opwekken, zal het ministerie van Defensie er zes voor zijn rekening nemen. Dat betekent een investering van ruim 19 miljoen euro. Deze investering wordt echter binnen tien jaar geheel terugverdiend. Het turbinepark past in de doelstelling dat bij Defensie, conform het Rijksbeleid, eind 2008 zo'n 75% van het elektriciteitsverbruik duurzaam wordt opgewekt.

    Full Text Available In traditional costing systems the emphasis is on the production volume and products units and also it is assumed that the products consume the resources. In activity based costing it is argued that the production of the products requires some activities and activities are consumers of the resources. Therefore in costing based on the activity initially overhead costs is allocated to the activities pile up of costs under the title of costs reservoirs and then the allocated costs to the activities are allocated based on a factor called cost driver to products or production lines. In activity based costing the major activities in the process of production are divided into four classes of product unit level product category level product support level and factory level. In the present research we aim to design a budgeting model with strategic planning approach and regarding the views of the elites and the previous researches a questionnaire is presented on the intended field and using the structural equations SEMs a model is presented in order to evaluate the parameters of the applied strategy in the Ministry of Power that according to the results related to the impact coefficient the greatest coefficient is related to the allocation of financial resources on financial strategy dimension with an impact factor value of 4.954.

    Full Text Available Nowadays most organizations have found that improving the quality of goods and services is the necessary condition to attend and survive in the market and in universal competition. ISO quality management system encompasses requirements for creating, deploying, implementing and maintaining quality management system. The purpose of this research is to investigate the effectiveness of implementing quality management system in some ministry of energy’s subsidiaries in Isfahan province to whom the ISO certificate is given. In order to do that, the research questionnaire was made and data was collected from statistical society containing managers of subsidiaries. The results show that in the above mentioned subsidiaries, after receiving ISO certificate, the desired goals of the quality management system has not been fulfilled generally. The results indicate that lack of knowledge about the capabilities of human resources in implementing the quality management system and lack of efficient staff, lack of continuous control and supervision, exclusiveness of the services and lack of competing conditions, lack of trust among senior managers about the usefulness of quality management system and also lack of sufficient support and relying on dissatisfactory old processes has paved the way for inefficiency of quality management system.

  3. Understanding HMIS Implementation in a Developing Country Ministry of Health Context - an Institutional Logics Perspective.

    Globally, health management information systems (HMIS) have been hailed as important tools for health reform (1). However, their implementation has become a major challenge for researchers and practitioners because of the significant proportion of failure of implementation efforts (2; 3). Researchers have attributed this significant failure of HMIS implementation, in part, to the complexity of meeting with and satisfying multiple (poorly understood) logics in the implementation process. This paper focuses on exploring the multiple logics, including how they may conflict and affect the HMIS implementation process. Particularly, I draw on an institutional logics perspective to analyze empirical findings from an action research project, which involved HMIS implementation in a state government Ministry of Health in (Northern) Nigeria. The analysis highlights the important HMIS institutional logics, where they conflict and how they are resolved. I argue for an expanded understanding of HMIS implementation that recognizes various institutional logics that participants bring to the implementation process, and how these are inscribed in the decision making process in ways that may be conflicting, and increasing the risk of failure. Furthermore, I propose that the resolution of conflicting logics can be conceptualized as involving deinstitutionalization, changeover resolution or dialectical resolution mechanisms. I conclude by suggesting that HMIS implementation can be improved by implementation strategies that are made based on an understanding of these conflicting logics.

    1991-01-01

    For thermal dismantling and cutting of metallic components, as electric arc, water jet cutting method was developed that can be used for underwater cutting work up to a depth of 20 m. Short-circuiting of a continuously fed electrode wire in contact with the metal generates an electric arc which induces partial melting of the metal, and the water jet surrounding the wire rinses away the molten material, thus making a continuous kerf in the material. The method was also tested and modified to allow larger area, surface cutting and removal of metallic surface coatings. This is achieved by melting parts of the surface with the electric arc and subsequent rinsing by the water jet. The cutting and melting depth for surface removal can be accurately controlled by the operating parameters chosen. (orig./DG) [de

    The results obtained during the INTEGRAL masks development program an implementing the HURA and MURA codes on tungsten plates of different thickness are presented. Hard scientific requirements on pixels size and location tolerances (tenths of microns over large areas -1 m 2 - and thickness from 0.5 mm to 60 mm) required the set up of a dedicated program for testing cutting technologies: laser, photochemical milling, spark machining and electro discharge wire cutting. After a very intensive test campaign the wire cutting process was selected as the optimum technology for code manufacturing . Accuracies achieved an the code cutting fulfill scientific requirements. In fact, they are 5 times better than required. Pixel size and centroids location accuracies of 0.01 mm over a 1 m 2 area have been obtained for the 10,000 pixels on IBIS, 100 pixels on SPI and 24000 pixels on JEM-X masks. Comparative results among different cutting technologies are also discussed. (author)

    Full Text Available Variety and complex interaction of physical processes during laser cutting is a critical characteristic of the laser cutting of metals. Small spatial and temporal scales complicate significantly the experimental investigations of the multi-phase fluid flow in the conditions of laser cutting of metals. In these conditions, the surface formed during the cutting is an indicator determining the melt flow character. The quantitative parameter reflecting the peculiarities of the multi-phase fluid flow, is normally the roughness of the forming surface, and the minimal roughness is the criterion of the qualitative flow [1 – 2]. The purpose of this work is to perform the experimental comparative investigation of the thermophysical pattern of the multi-phase melt flow in the conditions of the laser cutting of metals with the laser wavelength of 10.6 μm and 1.07 μm.

    Stems of Chenopodium album. and Sinapis arvensis. and leaves of Lolium perenne. were cut with a CO2 laser or with a pair of scissors. Treatments were carried out on greenhouse-grown pot plants at three different growth stages and at two heights. Plant dry matter was measured 2 to 5 weeks after...... treatment. The relationship between dry weight and laser energy was analysed using a non-linear dose-response regression model. The regression parameters differed significantly between the weed species. At all growth stages and heights S. arvensis was more difficult to cut with a CO2 laser than C. album....... When stems were cut below the meristems, 0.9 and 2.3 J mm(-1) of CO2 laser energy dose was sufficient to reduce by 90% the biomass of C. album and S. arvensis respectively. Regrowth appeared when dicotyledonous plant stems were cut above meristems, indicating that it is important to cut close...

    Full Text Available Bohorodyts'ka and Starosamars'ka hundred (sotnyais an unique Cossack formations. They existed in a territorial isolation from the Hetmanate and Slobozhanshchyna, on the lands of the Zaporozhian Sich. The study of these formations will better understand the policy of the Russian government in relation to the Sich, to find out the methods by which the state authorities planned to put Zaporizhzhya Cossacks under their control. We do not know when the Bohorodyts'ka hundred (sotnya arose. Now the first mention in the documents dates back to 1700. The Russian government planned to create a Cossack regiment (polk here, but in reality was founded a Cossack hundred (sotnya. Ivan Mazepa, as an autonomous ruler, wanted to include this formation in the structure of Hetmanate, but a hundred (sotnya was subject to the authority of a representative of the Russian administration – the Kiev governor. The hundreds (sotnya were liquidated as a result of Russia's defeat in the war with Turkey and the signing of the Prut peace in 1711. We do not know when the Cossack hundred (sotnya was restored under the name Starosamars'ka. This happened in the late 1730s – early 1740s. In 1744, the Starosamarsʼka hundreds became part of the Poltava regiment (polk of the Hetmanate. The administrative apparatus of the hundreds was predominantly similar to other hundreds of Hetmanates, but the real power of the Cossack officers was a bit lower here. During the existence of the Starosamars'ka hundreds, such a body of self-government was preserved as a council (rada that was not typical for the Hetmanate in this period. This was due to the fact that the peoples could easily escape from their power and move to neighboring settlements and recognize the jurisdiction of the Zaporozhska Sich. The population of hundreds and officers consisted mainly of immigrants from the left bank of the Dnieper, to a lesser extent – from immigrants from the right bank. Summing up, I note that the

    Customized cutting block (CCB) was designed to ensure the accurate alignment of knee prostheses during total knee arthroplasty. Given the paucity of CCB efficacy data, we compare CCB with conventional cutting guide using a randomized controlled trial. One hundred eight osteoarthritic knee patients underwent total knee arthroplasty by one experienced surgeon were randomized to receive CCB (n = 54) or conventional cutting instrument (CCI) surgery (n = 54). The primary outcomes were limb alignment, prostheses position, and operative time. The secondary outcomes were hemodynamic alteration after surgery, functional outcomes (modified Western Ontario and McMaster University Osteoarthritis Index) and range of motion at 2 years after surgery. Mean hip-knee-ankle angle in the CCB group was 179.4° ± 1.8° vs 179.1° ± 2.4° in the CCI group, Δ = 0 (95% confidence interval [CI] -0.6 to 1.1, P = .55). Mean operative time was faster in the CCB arm: 93 ± 12 vs 104 ± 12 minutes, Δ = 11 (95% CI -16.7 to -7.2, P < .0001). There were no differences in hemodynamic parameters, mean blood loss (446 [CCB] vs 514 mL [CCI], Δ = -68 [95% CI -138 to 31 mL, P = .21]), postoperative hemoglobin changes, incidence of hypotension (systolic <90 mm Hg), oliguria, and rates of blood transfusion. Functional outcomes and range of motion were also similar. There was no improvement in alignment, hemodynamic changes, blood loss, and knee functional outcomes. CCB reduced surgical time by 11 minutes in our population. CCB cost-effectiveness should be further investigated. Copyright © 2017 Elsevier Inc. All rights reserved.

    In most countries where Internet is widely used the number of people surfing the web for healthcare information equals (and in some countries is more than) the number of people looking for healthcare assistance. More and more often, all over the world, Internet is integrated by advanced healthcare systems as a cornerstone of their e-health infrastructure, to meet citizens' needs for health information. Therefore, information plays a key role in the relationship between healthcare providers and citizenship. In 2010 the Italian Ministry of Health has worked out a set of guidelines to improve online communication, within the framework of health promotion. To analyze if the web sites of the Italian public hospitals (PH) and the local healthcare units (LHU) comply with the guidelines of the Italian Ministry of Health (IMH) on the improvement of online communication within the framework of healthcare promotion. All Italian PH and LHU web sites have been analyzed using the self evaluation tool of the IMH. The total number of web sites analyzed was 245. Their compliance with the IMH guidelines was low. Web sites linking to other professional sites, such as the College of Physicians, the College of Pharmacists, or the College of Nurses, were 32 (13%). One hundred and forty-two (58%) were the sites that did not offer any kind of health information, such as pathophysiology of diseases, the most relevant pathologic conditions, risky behaviors, primary and secondary prevention's interventions. A web navigation menu organized according to the most relevant life events or according to categories of users (I am ... /dedicated to...) was available only in 53 web sites (22%). The IMH's guidelines on online communication -- with reference to the aspects here analyzed -- have been in some ways disregarded and the criteria suggested by them have not been fully adopted by PHs and LHUs. Overall, communication is globally meant (and directed) "towards" citizenship and not "together with

    Abstract Most low- and middle-income countries face financing pressures if they are to adequately address the recommendations of the Global Strategy for Women’s, Children’s and Adolescent’s Health. Negotiations between government ministries of health and finance are a key determinant of the level and effectiveness of public expenditure in the health sector. Yet ministries of health in low- and middle-income countries do not always have a good record in obtaining additional resources from key decision-making institutions. This is despite the strong evidence about the affordability and cost–effectiveness of many public health interventions and of the economic returns of investing in health. This article sets out 10 attributes of effective budget requests that can address the analytical needs and perspectives of ministries of finance and other financial decision-makers. We developed the list based on accepted economic principles, a literature review and a workshop in June 2015 involving government officials and other key stakeholders from low- and middle-income countries. The aim is to support ministries of health to present a more strategic and compelling plan for investments in the health of women, children and adolescents. PMID:27274599

    The recent spread of carbon oxide laser cutter is so startlingly fast, but at the same time, water jet cutting using ultra high pressure water stream is drawing attention as it has identical characteristics, and opens the way to cutting materials that have been hitherto difficult to cut. The authors, who are fabricators of cutters of both types, gave the comparisons and explanations on several examples referring to materials that can be cut, cutting accuracy, speed, shape and thermal effects to cut face, and running cost in detail. However, simple comparison is difficult. For instance, cutting 6 mm thick SUS sheet costs a running cost of 65 yen per meter in laser cutting, and 535 yen per meter in water jet cutting, but this situation is often reversed when other material or sheet thickness is selected. The actual situation in the sheet metal processing industry at the present time is that it uses by far more laser processing machines, and uses water jet cutters to supplement for cutting materials more difficult to cut. 10 figs., 3 tabs.

    A Kevlar laminate has negative thermal expansion coefficient, which makes it difficult to machine at room temperaures using the conventional cutting tools. Contararily, laser machining of a Kevlar laminate provides advantages over the conventional methods because of the non-mechanical contact between the cutting tool and the workpiece. In the present study, laser circular cutting of Kevlar laminate is considered. The experiment is carried out to examine and evaluate the cutting sections. Temperature and stress fields formed in the cutting section are simulated in line with the experimental study. The influence of hole diameters on temperature and stress fields are investigated incorporating two different hole diameters. It is found that the Kevlar laminate cutting section is free from large size asperities such as large scale sideways burnings and attachemnt of charred residues. The maximum temperature along the cutting circumference remains higher for the large diameter hole than that of the small diameter hole. Temperature decay is sharp around the cutting section in the region where the cutting terminates. This, in turn, results in high temperature gradients and the thermal strain in the cutting region. von Mises stress remains high in the region where temperature gradients are high. von Mises stress follows similar to the trend of temperature decay around the cutting edges.

    Brain and heart activities were measured in 31 veal calves during restraining and rotating followed by neck cutting with or without stunning to evaluate welfare. After neck cutting correlation dimension analyses and %power of EEG beta wave fraction decreased gradually to lower values resulting in an induction of unconsciousness lasting on average 80s. Corneal reflex response ceased 135±57s after neck cutting. The CD scores and the %power of beta waves fell immediately after post-cut captive bolt and pre-cut electrical stunning to levels indicating unconsciousness. Heart rate in lairage increased upon entrance to the restrainer and again after rotation, heart rate variability decreased. Rotating the restrainer 90°, 120° or 180° compromised veal calf welfare and should be avoided. It is recommended to use post-cut captive bolt stunning or pre-cut electrical stunning inducing immediate unconsciousness. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Westinghouse capitalizes more than 30 years of experience in the cutting of internal components of reactor and their packaging in view of their storage. Westinghouse has developed and validated different methods for cutting: plasma torch cutting, high pressure abrasive water jet cutting, electric discharge cutting and mechanical cutting. A long feedback experience has enabled Westinghouse to list the pros and cons of each cutting technology. The plasma torch cutting is fast but rises dosimetry concerns linked to the control of the cuttings and the clarity of water. Abrasive water jet cutting requires the installation of costly safety devices and of an equipment for filtering water but this technology allows accurate cuttings in hard-to-reach zones. Mechanical cutting is the most favourable technology in terms of wastes generation and of the clarity of water but the cutting speed is low. (A.C.)

    This is a multi-centre study to determine cost efficiency and cost effectiveness of the Ministry of Health centre haemodialysis and continuous ambulatory peritoneal dialysis (CAPD) programme. Forty-four haemodialysis and 11 CAPD centres were enrolled in this study in 2001. Sixty patients, 30 from each modality, were evaluated. Micro-costing was used to determine costs. The number of haemodialyses conducted ranged from 402 to 23,000 procedures per year, while for CAPD, output ranged from 70 to 2300 patient months/year. Cost ranged from RM79.61 to RM475.79 per haemodialysis treatment, with a mean cost of RM169 per HD (USD 1 = RM 3.80). The cost of CAPD treatment ranged from RM1400 to RM3200 per patient month, with a mean of RM2186. Both modalities incurred similar outpatient costs. The cost of erythropoeitin per year is RM4500 and RM2500 for haemodialysis and CAPD, respectively. The number of life years saved is 10.96 years for haemodialysis and 5.21 years for CAPD. Cost per life year saved is RM33 642 for haemodialysis and RM31 635 for CAPD. The cost for land, building, equipment, overheads, and staff were higher for haemodialysis, while consumables and hospitalization cost more for CAPD. Sensitivity analysis was performed for two discount rates (3 and 5%), varying erythropoietin doses and maximum and minimum overheads. Relative cost effectiveness of haemodialysis and CAPD was unchanged in all sensitivity scenarios, except for overhead costs, which influenced the cost effectiveness of HD. It is economically viable to promote the use of both CAPD and haemodialysis because the cost effectiveness of both are nearly equal.

Infant mortality rates are the main determinants of the under-five mortality rate, which is used for the developmental ranking of countries by the United Nations Children’s Fund (UNICEF. It is also an important indicator for assessing the maternal and child health status of a country and for calculating life expectancy at birth. The aim of this review is to reassess the calculations that were made in recent years in Turkey in the light of the criteria mentioned in the text and to guide the steps that need to be taken to make future calculations.Methods: The infant mortality rates of Turkey were collected, and their values and methods of calculating the rates were compared. Results:According to the Annual Reports of Health Statistics by Ministry of Health, the infant mortality rate has dropped from 29,0% in 2003 to 7,4% in 2012 in Turkey; but in these reports, infant mortality rates were taken from various studies and by various methods and presented in the same charts. In the data of the Turkish Statistical Institute (TSI, UNICEF and the Turkey Demographic and Health Survey (TDHS and in references used, this value was reported by different numbers (11,6 and 12% for 2012; 13,6% for 2013, respectively. Conclusions: The infant mortality rate must be calculated by a scientific approach and with definitions according to international standards in terms of comparability. This must be consistent between countries and between years studied so that the report can be compared according to consistent standards.Keywords: Infant mortality rate, calculation of infant mortality rate, life expectancy at birth, Turkey

    1975-01-01

    The regulation applies to the design, construction, reconstruction, and operation of any medical establishment, facilities using radioactive substances for diagnostic, therapeutic, or research purposes. Designs for nuclear medicine laboratories (or departments) must be approbated by, and commissioning performed with the participation of representatives of the State Sanitary Control. Use of radioactive materials is licensed by the Ministry of Public Health and the Committee for Peaceful Uses of Atomic Energy. Radiation safety responsibility is assigned to a specific staff member of the laboratory (or department). Any receipt or transfer of radioactive material is entered into appropriate records, acts, or requests. Special storage facilities must be available; their design and equipment have to meet the particular requirements for the corresponding class of work, as determined by the activity levels, radiotoxicities, and physical conditions of the radioactive substances used. With storage of unsealed sources, the class is at least second. Sealed source treatment requires primarily protection from external exposure. In such cases provisions are made for one basic and one intermediate storage facility; an applicator preparation room; and application room; a sterilization room; a surgery room; wards; toilets and washrooms for patients treated; a routine manipulation room; and a stock room. A number of safety rules in handling sealed sources are listed. A detailed system of radiation protection safeguards and rules is prescribed with regard to ventilation, sewer systems, remote control devices, work clothing and gloves, etc. Handling of unsealed radioactive materials used for diagnostic or research purposes should meet the requirements placed upon the respective radioisotope laboratory class, which has to be at least second.

    Introduction: The current study aims to assess the level of patients’ satisfaction and the factors contributing to patients’ satisfaction toward family physicians (FPs) consultation, visiting primary healthcare centers (PHCCs) working under Ministry of Health, Jeddah. Materials and Methods: In this cross-sectional study conducted in Jeddah from November 1, 2016 to March 1, 2017, we used consultation satisfaction questionnaire and its four subscales with standard cutoffs. These subscales include general satisfaction, professional care, depth of relationship, and length of consultation. Mean scores along with standard deviation of these subscales were measured. Independent sample t-test, ANOVA, and multivariate regression analysis were performed to test the association between satisfaction level and predictors. Results: Overall, patients’ satisfaction was 60%. Around 74% of patients were satisfied with the professional care and 58% with the depth of the relationship. Around 60% of patients need more consultation time with the physicians. Knowledge about the presence of FP in the nearest PHCCs was around 70%. Multivariate regression analysis for the overall high satisfaction showed that the most important predictors of this high satisfaction level are regular visits to a particular FP (P < 0.001), distance from the PHCC (P = 0.044) and gender of the patient (P = 0.027). Conclusion: This study concluded that satisfaction with the FP's consultation is acceptable but needs improvement. Lower satisfaction was reported among males, patients living at a distance from PHCC and who had less knowledge about the presence of FP in their nearest PHCC. Such study data are vital for any corrective measures to boost satisfaction in patients attending PHCCs. PMID:29564270

    Introduction The levels of physicians' job satisfaction and burnout directly affect their professionalism, punctuality, absenteeism, and ultimately, patients' care. Despite its crucial importance, little is known about professional burnout of the physicians in Saudi Arabia. The objectives of this research are two-fold: (1) To assess the prevalence of burnout in physicians working in primary health care centers under Ministry of Health; and (2) to find the modifiable factors which can decrease the burnout ratio. Methodology Through a cross-sectional study design, a representative sample of the physicians working in primary health care centers (PHCCs) Jeddah (n=246) was randomly selected. The overall burnout level was assessed using the validated abbreviated Maslach burnout inventory (aMBI) questionnaire. It measures the overall burnout prevalence based on three main domains i.e., emotional exhaustion, depersonalization, and personal accomplishment. Independent sample T-test, analysis of variance (ANOVA), and multivariate regression analysis were performed using Statistical Package for the Social Sciences (SPSS Version 22, IBM, Armonk, NY). Results Overall, moderate to high burnout was prevalent in 25.2% of the physicians. Emotional exhaustion was noted in 69.5%. Multivariate regression analysis showed that patient pressure/violence (p burnout. The patient's pressure/violence was the only significant independent predictor of overall burnout. Conclusion Emotional exhaustion is the most prominent feature of overall burnout in the physicians of primary health care centers. The main reasons include patient's pressure/violence, unorganized patient flow, less cooperative colleague doctors, fewer support services at the PHCCs, more paperwork, and less cooperative colleagues. Addressing these issues could lead to a decrease in physician's burnout.

  13. The English Proficiency Test of the Iranian Ministry of Science, Research, and Technology: A Review

    Full Text Available One of the serious decisions which every administrator may need to make during his/her professional career is to select or reject applicants based on their general language skills or competence. These significant decisions, which may be of serious consequences not only for the individuals but also for the society in general, are occasionally made based on norm-referenced proficiency tests. Out of internationally available proficiency tests such as the TOEFL test, those which fit the specific local cultural and academic contexts seem of greater prominence. One such test, which has been specifically designed for the Iranian EFL context by the Ministry of Science, Research, and Technology, is the MSRT proficiency test. While a few studies have been conducted on the analysis of the reliability and validity of the mentioned test, no study has yet reviewed the test and its component parts. Therefore, the current study aimed at considering the strengths and weaknesses of the test in general and its component items in particular. The results implicated that the MSRT benefits from more efficient general reliability and validity, well planned language items, practicality, ease of administration, objective scoring, ease of accessibility, as well as reasonable fees, while it needs to be more substantiated in terms of the inclusion of the speaking skill assessment, the computerized adaptive assessment procedures, and the correction factor for guessing. In addition, the use of the individual-based listening apparatus for testing listening comprehension as well as the consideration of the integrative communicative tests for its concurrent validity purposes can contribute to more appropriate distinction of proficient and non-proficient applicants.

    Deferment cutting is a regeneration practice that resembles a seed-tree or shelterwood cutting. The difference is that residual trees are not cut when the reproduction becomes established. Instead, residual trees are left until new reproduction matures to sawtimber size, and another regeneration cut is the silvicultural objective. Hence, with deferment cutting specific...

    We study cut elimination for a multifocused variant of full linear logic in the sequent calculus. The multifocused normal form of proofs yields problems that do not appear in a standard focused system, related to the constraints in grouping rule instances in focusing phases. We show that cut...... elimination can be performed in a sensible way even though the proof requires some specific lemmas to deal with multifocusing phases, and discuss the difficulties arising with cut elimination when considering normal forms of proofs in linear logic....

    1995-01-01

    Two grooves each of a predetermined depth are formed along a surface of a structural component, and a portion between the two grooves is cut in the direction of the depth from the surface of the structural component by using a cutting wire of a wire saw device. Then, the cutting wire is moved in the extending direction of the grooves while optionally changing the position in the direction of the depth to conduct cutting for the back face. Further, the cutting wire is moved in the direction of the depth of the groove toward the surface, to cut a portion between the two grooves. The wire saw device comprises a wire saw main body movable along the surface of the structural component, a pair of wire guide portions extending in the direction of the depth, guide pooleys capable of guiding the cutting wire guides revolvably and rotatably disposed at the top end, and an endless annular cutting wire extending between the wire guide portions. Thus, it is possible to continuously cut out blocks set to optional size and thickness. In addition, remote cutting is possible with no requirement for an operator to access to the vicinity of radioactivated portions. (N.H.)

  2. An FMS Dynamic Production Scheduling Algorithm Considering Cutting Tool Failure and Cutting Tool Life

    International Nuclear Information System (INIS)

    Setiawan, A; Wangsaputra, R; Halim, A H; Martawirya, Y Y

    2016-01-01

    This paper deals with Flexible Manufacturing System (FMS) production rescheduling due to unavailability of cutting tools caused either of cutting tool failure or life time limit. The FMS consists of parallel identical machines integrated with an automatic material handling system and it runs fully automatically. Each machine has a same cutting tool configuration that consists of different geometrical cutting tool types on each tool magazine. The job usually takes two stages. Each stage has sequential operations allocated to machines considering the cutting tool life. In the real situation, the cutting tool can fail before the cutting tool life is reached. The objective in this paper is to develop a dynamic scheduling algorithm when a cutting tool is broken during unmanned and a rescheduling needed. The algorithm consists of four steps. The first step is generating initial schedule, the second step is determination the cutting tool failure time, the third step is determination of system status at cutting tool failure time and the fourth step is the rescheduling for unfinished jobs. The approaches to solve the problem are complete-reactive scheduling and robust-proactive scheduling. The new schedules result differences starting time and completion time of each operations from the initial schedule. (paper)

    Buioca, C.D.; Iusan, Vasile; Pirlea, Remus

    2002-01-01

    The nondestructive testing of cutting knives consists in the determination of nonuniformity of a magnetic fluid layer applied on the horizontally placed surface of the magnetized cutting plate of the knife. A low constant magnetic field was applied perpendicular to the knife surface and a uniform magnetic fluid layer was applied. The defects as nonuniform brass layer, fissures or small cavities between the cutting plate and knife core determine the apparition of magnetic field gradients and therefore magnetic forces acting on the magnetic fluid which migrates to the zones with higher magnetic field intensity. After several minutes, a nonuniform layer of magnetic fluid was directly observed. Quantitative results, concerning the position and dimensions of the defect, were obtained by computer aided processing of the magnetic fluid layer image. Experimental data for several cutting knives are presented in the paper

  4. Automated Cell-Cutting for Cell Cloning

    Ichikawa, Akihiko; Tanikawa, Tamio; Matsukawa, Kazutsugu; Takahashi, Seiya; Ohba, Kohtaro

    We develop an automated cell-cutting technique for cell cloning. Animal cells softened by the cytochalasin treatment are injected into a microfluidic chip. The microfluidic chip contains two orthogonal channels: one microchannel is wide, used to transport cells, and generates the cutting flow; the other is thin and used for aspiration, fixing, and stretching of the cell. The injected cell is aspirated and stretched in the thin microchannel. Simultaneously, the volumes of the cell before and after aspiration are calculated; the volumes are used to calculate the fluid flow required to aspirate half the volume of the cell into the thin microchannel. Finally, we apply a high-speed flow in the orthogonal microchannel to bisect the cell. This paper reports the cutting process, the cutting system, and the results of the experiment.

    1991-01-01

    With the change-out of equipment at nuclear power plants comes large quantities of low level contaminated metallic waste. Of particular concern are large heat exchangers, preheaters and steam generators. These bulky items consume huge volumes of burial space. The need for volume reduction and recycling of these metals has created new demands for 'how' to cut heat exchangers into useful sizes for decontamination, melting or compaction. This paper reviews the cutting solution provided by a diamond wire system, with particular regard for cutting of a Ringhals Preheater Bundle at Studsvik Nuclear in 1989. The background of diamond wire sawing is discussed and basic components of wire sawing are explained. Other examples of wire cutting decommissioned components are also given. (author)

    The Tokamak Fusion Test Reactor (TFTR) ceased operation in April 1997 and decommissioning commenced in October 1999. The deuterium-tritium fusion experiments resulted in contaminating the vacuum vessel with tritium and activating the materials with 14 Mev neutrons. The total tritium content within the vessel is in excess of 7,000 Curies while dose rates approach 50 mRem/hr. These radiological hazards along with the size of the Tokamak (100 cubic meters) present a unique and challenging task for dismantling. Plasma arc cutting is the current baseline technology for the dismantlement of fission reactors. This technology is typically used because of its faster cutting times. Alternatively, an innovative approach for dismantlement of the TFTR is the use of diamond wire cutting technology. Recent improvements in diamond wire technology have allowed the cutting of carbon steel components such as pipe, plate, and tube bundles in heat exchangers. Some expected benefits of this technology include: significantly reduction in airborne contaminates, reduced personnel exposure, a reduced risk of spread of tritium contamination, and reduced overall costs as compared to using plasma arc cutting. This paper will provide detailed results of the diamond wire cutting demonstration that was completed in September of 1999, on a mock-up of this complex reactor. The results will identify cost, safety, industrial and engineering parameters, and the related performance of each situation

    The classical max-flow min-cut theorem describes transport through certain idealized classical networks. We consider the quantum analog for tensor networks. By associating an integral capacity to each edge and a tensor to each vertex in a flow network, we can also interpret it as a tensor network and, more specifically, as a linear map from the input space to the output space. The quantum max-flow is defined to be the maximal rank of this linear map over all choices of tensors. The quantum min-cut is defined to be the minimum product of the capacities of edges over all cuts of the tensor network. We show that unlike the classical case, the quantum max-flow=min-cut conjecture is not true in general. Under certain conditions, e.g., when the capacity on each edge is some power of a fixed integer, the quantum max-flow is proved to equal the quantum min-cut. However, concrete examples are also provided where the equality does not hold. We also found connections of quantum max-flow/min-cut with entropy of entanglement and the quantum satisfiability problem. We speculate that the phenomena revealed may be of interest both in spin systems in condensed matter and in quantum gravity.

Recent improvements in diamond wire technology have allowed the cutting of carbon steel components such as pipe, plate, and tube bundles in heat exchangers. Some expected benefits of this technology include: significantly reduction in airborne contaminates, reduced personnel exposure, a reduced risk of spread of tritium contamination, and reduced overall costs as compared to using plasma arc cutting. This paper will provide detailed results of the diamond wire cutting demonstration that was completed in September of 1999, on a mock-up of this complex reactor. The results will identify cost, safety, industrial and engineering parameters, and the related performance of each situation.

  15. Theoretical aspects of fibre laser cutting

    Fibre lasers offer distinct advantages over established laser systems with respect to power efficiency, beam guidance and beam quality. Consequently, the potential of these new laser beam sources will be increasingly exploited for laser cutting applications that are conventionally carried out with CO{sub 2} lasers. However, theoretical estimates of the effective absorptivity at the cut front suggest that the shorter wavelength of the fibre laser in combination with its high focusability seems to be primarily advantageous for thin sheet metal cutting whereas the CO{sub 2} laser is probably still capable of cutting thicker materials more efficiently. This surprising result is a consequence of the absorptivity behaviour of metals that shows essential quantitative differences for the corresponding wavelengths of both laser sources as a function of the angle of incidence between the laser beam and the material to be cut. In evaluation of the revealed dependences, solution strategies for an improvement of the efficiency of fibre laser cutting of thicker metal sheets are suggested.

    The classical max-flow min-cut theorem describes transport through certain idealized classical networks. We consider the quantum analog for tensor networks. By associating an integral capacity to each edge and a tensor to each vertex in a flow network, we can also interpret it as a tensor network and, more specifically, as a linear map from the input space to the output space. The quantum max-flow is defined to be the maximal rank of this linear map over all choices of tensors. The quantum min-cut is defined to be the minimum product of the capacities of edges over all cuts of the tensor network. We show that unlike the classical case, the quantum max-flow=min-cut conjecture is not true in general. Under certain conditions, e.g., when the capacity on each edge is some power of a fixed integer, the quantum max-flow is proved to equal the quantum min-cut. However, concrete examples are also provided where the equality does not hold. We also found connections of quantum max-flow/min-cut with entropy of entanglement and the quantum satisfiability problem. We speculate that the phenomena revealed may be of interest both in spin systems in condensed matter and in quantum gravity.

    In Article 16 of Stockholm Convention for the global elimination of Persistent Organic Pollutants (POPs), it is written that ''comparable monitoring data'' reported by the Parties will be used for the ''effectiveness evaluation of the Convention''. A detailed evaluation scheme will be decided by the Conference of the Parties, but various technical aspects of this POPs monitoring were discussed by the international experts at UNEP Chemical's workshop on the development of Global POPs Monitoring held in Geneva in March 2003, and the guidance documents for the monitoring are now being prepared based on the results of the workshop. The Ministry of the Environment (MoE), Japan, has been conducting environmental monitoring of various pollutants including major POPs in Japan for more than two decades, and reported the results every year in a report ''Chemicals in the Environment'' (or KUROHON, meaning ''black book'' in Japanese). Originally a conventional GC/ECD method had been employed for the analysis of organochlorine chemicals (OCs) in biological samples. Then a GC/MS (low resolution) was introduced for OCs analysis in sediments and water, and GC/high resolution(HR)-MS method was introduced for dioxins analysis from around 1990. Due to general decline of POPs levels in the environment, the number of ND (not detected = less than detection limits) data had been increasing in recent years, and consequently it became difficult to extract temporal trends from the monitoring data. In 2002, MoE decided to reorganize the environmental monitoring framework in order to respond to the request of POPs convention, and re-started POPs monitoring by using more sensitive GC/HR-MS method for the analysis of nine POPs chemicals (dioxins and furans have already been monitored by the method; toxaphene is analyzed by GC/negative ionization-MS). The primary purpose of this reorganization is to reveal

    Introduction The levels of physicians' job satisfaction and burnout directly affect their professionalism, punctuality, absenteeism, and ultimately, patients' care. Despite its crucial importance, little is known about professional burnout of the physicians in Saudi Arabia. The objectives of this research are two-fold: (1) To assess the prevalence of burnout in physicians working in primary health care centers under Ministry of Health; and (2) to find the modifiable factors which can decrease the burnout ratio. Methodology Through a cross-sectional study design, a representative sample of the physicians working in primary health care centers (PHCCs) Jeddah (n=246) was randomly selected. The overall burnout level was assessed using the validated abbreviated Maslach burnout inventory (aMBI) questionnaire. It measures the overall burnout prevalence based on three main domains i.e., emotional exhaustion, depersonalization, and personal accomplishment. Independent sample T-test, analysis of variance (ANOVA), and multivariate regression analysis were performed using Statistical Package for the Social Sciences (SPSS Version 22, IBM, Armonk, NY). Results Overall, moderate to high burnout was prevalent in 25.2% of the physicians. Emotional exhaustion was noted in 69.5%. Multivariate regression analysis showed that patient pressure/violence (p <0.001), unorganized patients flow to clinics (p=0.021), more paperwork (p<0.001), and less co-operative colleague doctors (p=0.045) were the significant predictors for high emotional exhaustion. A positive correlation was noted between the number of patients per day and burnout. The patient’s pressure/violence was the only significant independent predictor of overall burnout. Conclusion Emotional exhaustion is the most prominent feature of overall burnout in the physicians of primary health care centers. The main reasons include patient’s pressure/violence, unorganized patient flow, less cooperative colleague doctors, fewer

    Laser cutting of various materials including Ti-6Al-4V alloy, steel 304, Inconel 625, and alumina is carried out to assess the kerf width size variation along the cut section. The life cycle assessment is carried out to determine the environmental impact of the laser cutting in terms of the material waste during the cutting process. The kerf width size is formulated and predicted using the lump parameter analysis and it is measured from the experiments. The influence of laser output power and laser cutting speed on the kerf width size variation is analyzed using the analytical tools including scanning electron and optical microscopes. In the experiments, high pressure nitrogen assisting gas is used to prevent oxidation reactions in the cutting section. It is found that the kerf width size predicted from the lump parameter analysis agrees well with the experimental data. The kerf width size variation increases with increasing laser output power. However, this behavior reverses with increasing laser cutting speed. The life cycle assessment reveals that material selection for laser cutting is critical for the environmental protection point of view. Inconel 625 contributes the most to the environmental damages; however, recycling of the waste of the laser cutting reduces this contribution.

    Götze, Elisa; Zanger, Frederik; Schulze, Volker

    2018-05-01

    The finishing process of parts manufactured by laser beam melting is of high concern due to the lack of surface accuracy. Therefore, the focus of this work lies on the influence of the build-up direction of the parts and their effect on the finishing process. The orthogonal cutting reveals findings in the fields of chip formation, involved forces and temperatures appearing during machining. In the investigations, the cutting depth was varied between 0.05 and 0.15 mm representing a finishing process and the cutting velocity ranges from 30 to 200 m/min depending on the material. The experiments contain the materials stainless steel (AISI 316L), titanium (Ti6Al4V) and nickel-base alloy (IN718). The two materials named latter are of high interest in the aerospace sector and at the same time titanium is used in the medical field due to its biocompatibility. For the materials IN718 and Ti6Al4V a negative rake angle of -7.5° and for stainless steel a rake angle of 12.5° are chosen for the cutting experiments. The results provide the base for processing strategies. Therefore, the specimens were solely laser beam melted without post-processing like heat treatment. The evaluation of the experiments shows that an increase in cutting speed has different effects depending on the material. For stainless steel the measured forces regarding the machining direction to the layers approach the same values. In contrast, the influence of the layers regarding the forces appearing during orthogonal cutting of the materials IN718 and Ti6Al4V differ for lower cutting speeds.

    The zirconium alloy tube of the impile creep test facility had been subjected to inner pressure in the Japan Material Testing Reactor (JMTR) environment. In the near future, it will be necessary to dismantle the facility and to take out the tube for such examinations as irradiation effects on material properties. In order to establish the dismantling technology for the radioactive facility, a study on underwater plasma arc cutting has been carried out since 1977. Primarily, optimum underwater cutting sequence and conditions were studied in details for developing the remote control handling and the cutting system. Further, the amounts of particles suspended in water as well as those contained in bubbled gas were quantitatively analyzed for developing a safe removal system for contaminants which were produced by cutting the radioactive material. As a result of this study, it has been concluded that the underwater plasma arc cutting method is generally suitable and effective for dismantling such radioactive material as the impile creep test facility of the JMTR.

    2007-01-01

    Powerful lasers represent a promising alternative solution to traditional cutting processes used in dismantling nuclear equipments. The use of optical fibers has an unquestionable advantage when dealing with airtight workshops. A study funded by COGEMA Marcoule was undertaken by IRSN/SERAC in collaboration with GIP/GERAILP in order to characterise the aerosols emitted by the cutting of evaporators elements with a 4 kW continuous wave Nd:YAG laser. For this study, laser cutting has been carried out in a tight room of 35 m 3 connected to a particle sampling pipe. Iso-kinetic samplers allowed the measurement of the aerosol concentration. A diffusional and inertial spectrometer (SDI 2001) - an Andersen impinger coupled to a diffusion battery - provided the size distribution. An electrostatic filter used upstream a HEPA filter, itself placed before the extractor fan, collected the majority of the emitted aerosol. Its efficiency was measured and controlled throughout the experiments. The results show the influence of the cutting conditions on the characteristics of the aerosol, and allow a comparison with other cutting tools. (authors)

    Chavand, J.; Gauthier, A.; Lopez, J.J.; Tanis, G.

    1985-01-01

    The objective of this contract was to study a new steel-sheet cutting technique for dismantling nuclear installations without in principle producing secondary waste. This technique is based on intergranular cracking of steel induced by the combined action of penetration of molten metal into the steel and application of a mechanical load. Cutting has been achieved for stainless-steel sheets with thicknesses ranging from a few mm to 50 mm and for carbon-steel plates with thicknesses between 20 and 60 mm. For carbon steel is seems possible that components as thick as 100 mm can be cut. The tests have permitted selection of the heating methods and determination of the cracking parameters for the materials and range of thickness studied. In the case of thin sheets, results were obtained for cutting in varied positions suited to the techniques of dismantling in hot cells. A temperature-measuring system using an infrared camera has been developed to determine the variation of the temperature field established in the component. In association with the three-dimensional computation code COCO developed by the CEA, this system permits prediction of the changes in stresses in the cracked zone when the cutting parameters are modified. 34 figs

    Cut welding is a newly developed cold pressure welding process. In the present work, an experimental investigation was carried out analyzing the mechanisms involved in cut welding of a block to a strip. Experiments were carried out in technically pure aluminium. The investigation has involved...... tensile testing and metallographic investigations of the welds. The results show that this variant of cut welding is a very reproducible process giving a weld strength equal to 30-40% the strength of the parent material. The experiments have shown that the reason for this relatively low strength...... is an uneven pressure distribution along the weld due to a wave formed during sliding. Attempts to alter the material flow during sliding are presented....

    The photonic band properties of random rotator mesophases are calculated using supercell methods applied to cut rods on a hexagonal lattice. Inspired by the thermodynamic mesophase for anisotropic building blocks, we vary the shape factor of cut fraction for the randomly oriented basis. We find large, stable bandgaps with high gap isotropy in the inverted and direct structures as a function of cut fraction, dielectric contrast, and filling fraction. Bandgap sizes up to 34.5% are maximized at high dielectric contrast for rods separated in a matrix. The bandgaps open at dielectric contrasts as low as 2.0 for the transverse magnetic polarization and 2.25 for the transverse electric polarization. Additionally, the type of scattering that promotes the bandgap is correlated with the effect of disorder on bandgap size. Slow light properties are investigated in waveguide geometry and slowdown factors up to 5 × 10{sup 4} are found.

    The biological shield concrete and the radiation shield concrete which construct a part of the atomic reactor must be demolished with the decommissioning of the atomic reactor plants. In a case, the demolition using a laser is expected as one of excellent method for the decommissioning of these radioactive concretes. The fundamental cuttings of a mortar, the concretes with andesite, lime stone and gray wacke as ballast and a concrete reinforced with mild steel rods were therefore carried out using a 5 kW output CO 2 laser. As the results of experiment, it was cleared that cutting results varied with ballasts, 100 mm thick reinforced concrete could be cut, safety was high because few dross and few fume were produced.

    2012-11-01

    Full Text Available Strained environment is a global problem. In metal industries the use of coolant has become more problematic in terms of both employee health and environmental pollution. It is said that the use of coolant forms approximately 8 - 16 % of the total production costs.The traditional methods that use coolants are now obviously becoming obsolete. Hence, it is clear that using a dry cutting system has great implications for resource preservation and waste reduction. For this purpose, a new cooling system is designed for dry cutting. This paper presents the new eco-friendly cooling innovation and the benefits gained by using this method. The new cooling system relies on a unit for ionising ejected air. In order to compare the performance of using this system, cutting experiments were carried out. A series of tests were performed on a horizontal turning machine and on a horizontal machining centre.

    The cutting processes used actually for nuclear facilities dismantling are, for the most mechanic or thermic processes already widely tested in various industrial sectors. Some of there are still in faisability studies or in focus sed prototypes. By the criteria to take into account in the choice of such process, for future dismantlings, it is shown that the emitted nuisances should be wellknown and correctly overcome, in view to reduce the cutting process impact on its environment. In the second part we present the IPSN research. We describe the actual state of works realized in collaboration between French and European teams, especially on nuisances characterizations (gas, aerosols) and the means to confine it (ventilation, source collecting, filtration). In the end of this text we indicate the interest for the realization of intercomparison program and for qualification of various cutting processes taking into account the nuisances aspects in view to extrapolate results obtained in inactive situation at those obtained in real dismantling situations [fr

    Full Text Available Thise paper deals with the application of laser technology and optimizing the parameters for cutting nickel alloy. The theoretical part of the paper describes various types of lasers, their principles and usage. The experimental part focuses on optimizing the section parameteres of Haynes 718 alloy using a CO2 gas laser. This alloy is employed in the production of components for the aircraft industry. The experiment was performed on the Wibro Delta laser system designed for sizable parts. The actual section is measured with respect to its quality and any accompanying side effects that occur during the process. In this case, laser output and cutting speed were the parameters with most influence on the final cut. The summary explains the results achieved in a metallographic laboratory.

  15. Metal Cutting for Large Component Removal

    2008-01-01

    Decommissioning of commercial nuclear power plants presents technological challenges. One major challenge is the removal of large components mainly consisting of the reactor vessel, steam generators and pressurizer. In order to remove and package these large components nozzles must be cut from the reactor vessel to precise tolerances. In some cases steam generators must be segmented for size and weight reduction. One innovative technology that has been used successfully at several commercial nuclear plant decommissioning is diamond wire sawing. Diamond wire sawing is performed by rotating a cable with diamond segments attached using a flywheel approximately 24 inches in diameter driven remotely by a hydraulic pump. Tension is provided using a gear rack drive which also takes up the slack in the wire. The wire is guided through the use of pulleys keeps the wire in a precise location. The diamond wire consists of 1/4 inch aircraft cable with diamond beads strung over the cable separated by springs and brass crimps. Standard wire contains 40 diamond beads per meter and can be made to any length. Cooling the wire and controlling the spread of contamination presents significant challenges. Under normal circumstances the wire is cooled and the cutting kerf cleaned by using water. In some cases of reactor nozzle cuts the use of water is prohibited because it cannot be controlled. This challenge was solved by using liquid Carbon Dioxide as the cooling agent. The liquid CO 2 is passed through a special nozzle which atomizes the liquid into snowflakes which is introduced under pressure to the wire. The snowflakes attach to the wire keeping it cool and to the metal shavings. As the CO 2 and metal shavings are released from the wire due to its fast rotation, the snowflakes evaporate leaving only the fine metal shavings as waste. Secondary waste produced is simply the small volume of fine metal shavings removed from the cut surface. Diamond wire sawing using CO 2 cooling has

    Sikora, W; Kusz, F; Fels, M

    1988-02-01

    Presents results of investigations into operation of the AM-50 heading machine. About 50% of headings, i.e. about 800 km/a, are driven by about 400 heading machines. It has been found that energy consumption depends on compression strength of rock and is 6 times higher for sandstone than for clayey shale. Power consumed by cutting heads depends mainly on the web used (30-150 mm depending on rock strength). Wear of cutting tools is 1-30 pieces per meter of heading advance at a working cross-section area of 15 m/sup 2/. The AM-50 machine uses cutting speeds of 1.1-3.5 m/s. Higher speeds negatively affect the resistance to cutting. Nonuniform tool wear on the cutting head circumference is an indication of improper head design that requires remedying.

    The aim of this work is to develop a laser cutting process model that can predict the relationship between the process input parameters and resultant surface roughness, kerf width characteristics. The research conduct is based on the Design of Experiment (DOE) analysis. Response Surface Methodology (RSM) is used in this work. It is one of the most practical and most effective techniques to develop a process model. Even though RSM has been used for the optimization of the laser process, this research investigates laser cutting of materials like Composite wood (veneer)to be best circumstances of laser cutting using RSM process. The input parameters evaluated are focal length, power supply and cutting speed, the output responses being kerf width, surface roughness, temperature. To efficiently optimize and customize the kerf width and surface roughness characteristics, a machine laser cutting process model using Taguchi L9 orthogonal methodology was proposed.

    Highlights: • Different TIG and Laser welding techniques are tested. • Twin spot laser welding techniques is the best. • Limited heat input gives a stable weld pool in all positions. • Penetrations is achieved. • Lip seal welding and cutting with a robotic arm is successfully performed on a representative mock-up. - Abstract: The welded lip seals form part of the torus primary vacuum boundary in between the port plugs and the vacuum vessel, and are classified as Protection Important Component. In order to refurbish the port plugs or the in-vessel components, port plugs have to be removed from the machine. The lip seal design must enable up to ten opening of the vacuum vessel during the life time operation of the ITER machine. Therefore proven, remote reliable cutting and re-welding are essential, as these operations need to be performed in the port cells in a nuclear environment, where human presence will be restricted. Moreover, the combination of size of the components to be welded (∼10 m long vacuum compatible thin welds) and the congested environment close to the core of the machine constraint the type and size of tools to be used. This paper describes the lip seal cutting and welding development programme performed at the VTT Technical Research Centre, Finland. Potential cutting and welding techniques are analyzed and compared. The development of the cutting, TIG and laser welding techniques on samples are presented. Effects of lip seal misalignments and optimization of the 2 welding processes are discussed. Finally, the manufacturing and test of the two 1.2 m × 1 m representative mock-ups are presented. The set-up and use of a robotic arm for the mock-up cutting and welding operations are also described.

    Laser with water jet is examined to cut in-vessel structure. However, it is necessary to increase the break-up length of water jet to cut a thick plate. Therefore, the effects of the water jet parameter (water pressure, assist gas, laser power) on break-up length were investigated. It was found from observation results of water jet that the longest break-up length is about 135mm under condition of water pressure 40 MPa, laser power 30W and helium assist gas 1L/min. (author)

    The present work is an attempt to develop a laser cutting method for cutting and removing stainless steel liners from concrete walls and floors in cells and fuel storage pools of nuclear facilities. The effects of basic laser cutting parameters such as cutting speed, assist gas flow etc. were first studied applying a 1 kW Nd:YAG laser to mock up concrete specimens lined with 3 mm thick stainless steel sheets. These initial studies were followed by studies on the effect of unevenness of the liner surface and on methods of confining contamination during the cutting process. The results showed that laser cutting is superior to other conventional cutting methods from the point of view of safety from radioactivity and work efficiency when cutting contaminated stainless steel liners. In addition to the above results, this paper describes the design outline of a laser cutting system for cutting stainless liners at site and evaluates its merit and cost performance. (author)

    Based on physical backgrounds, the four time series of the Guliya (Tibetan plateau) ice core (GIC) δ 18 O, and three natural factors, i.e. the rotation rate of earth, sunspots, and El Nino–Southern Oscillation (ENSO) signals, are decomposed into two hierarchies, i.e. more and less than 10-year hierarchies respectively, and then the running t-test is used to reanalyse the data before and after filtering with the purpose of investigating the contribution of natural factors to the abrupt climate changes in the last one hundred years. The results show that the GIC δ 18 O evolved with a quasi-period of 7–9 years, and the abrupt climate changes in the early 1960s and in the period from the end of the 1970s to the beginning of the 1980s resulted from the joint effect of the two hierarchies, in other words, the two interdecadal abrupt changes of climate in the last one hundred years were global. The interannual variations of ENSO and sunspots were the important triggering factors for the abrupt climate changes in the last one hundred years. At the same time, the method of Information Transfer (IT) is employed to estimate the contributions of ENSO signals and sunspots activities to the abrupt climate changes, and it is found that the contribution of the interannual variation of ENSO signals is relatively large

    In Kawasaki Heavy Industries, Ltd., the development of a remote dismantling system by underwater plasma arc cutting process has been advanced, expecting its application to the dismantling and removal of nuclear reactor facilities. In the previous two reports, the fundamental experimental results such as the comparison of the cutting capability in air and in water were shown, but this time, the remote automatic cutting of wedge-shaped specimens was carried out, using a newly installed manipulator for underwater works, therefore its outline is reported. Also the cutting experiment by overhead position and vertical position was performed by using the same equipment, and comparison was made with the cutting capability by downhand and horizontal positions. It is important to grasp the cutting characteristics in the case of upward advancing and downward advancing cuttings by overhead and vertical positions when the cutting of pressure vessels and horizontal pipes into rings is supposed. The experimental apparatus, the cutting conditions, the testing method and the test results of the cutting capability test, the test of changing direction during cutting, and the remote cutting of pipes into rings are described. The underwater plasma arc cutting can cut all metals, the cutting speed is relatively high, and the apparatus is simple and compact. (Kako, I.)

    Service performance of components such as fatigue life are dramatically influenced by the machined surface and subsurface residual stresses. This paper aims at achieving a better understanding of the influence of cutting edge microgeometry on machined surface residual stresses during orthogonal dry cutting of Inconel 718. Numerical and experimental investigations have been conducted in this research. The cutting edge microgeometry factors of average cutting edge radius S¯, form-factor K , and chamfer were investigated. An increasing trend for the magnitudes of both tensile and compressive residual stresses was observed by using larger S¯ or introducing a chamfer on the cutting edges. The ploughing depth has been predicted based on the stagnation zone. The increase of ploughing depth means that more material was ironed on the workpiece subsurface, which resulted in an increase in the compressive residual stress. The thermal loads were leading factors that affected the surface tensile residual stress. For the unsymmetrical honed cutting edge with K = 2, the friction between tool and workpiece and tensile residual stress tended to be high, while for the unsymmetrical honed cutting edge with K = 0.5, the high ploughing depth led to a higher compressive residual stress. This paper provides guidance for regulating machine-induced residual stress by edge preparation.

    The objective of the present study is to analyze and compare the cutting performance of segmented diamond blades when dry-cutting concrete. A cutting criteria is proposed to characterize the wear of the blades by measuring the variation of the external diameter and the weight loss of the blade. The results exhibit the cutting blade SB-A, which has twice the density of diamonds and large contact area, exhibits less wear even though the material removal rate is higher compared with the other two cutting blades. Additionally, the surface topography of the different blades is evaluated to examine the impact of wear depending on the surface profile and the distribution of the diamonds in the blade's matrix. Large number of diamonds pull-out are found in blades type SB-C, which additionally shows the worst wear resistant capability. As a conclusion, the cutting efficiency of the blade is found to be related to the density of embedded diamonds and the type of the surface profile of the cutting blade after reaching the stop criteria.

    1977-09-01

    The forces during cryosectioning were measured using miniature strain gauges attached to a load cell fitted to the drive arm of the Porter-Blum MT-2 cryomicrotome. Work was calculated and the data normalized to a standard (1 mm X 1 mm X 0.5 micrometer) section. Thermal energy generated was also calculated. Five parameters were studied: cutting angle, thickness, temperature, hardness, and block shape. Force patterns could be divided into three major groups thought to represent cutting (Type I), large fracture planes greater than 10 micrometer in length (Type II), and small fracture planes less than 10 micrometer in length (Type III). Type I and Type II produced satisfactory sections. Work in cutting ranged from an average of 78.4 muJ to 568.8 muJ. Cutting angle and temperature had the greatest effect on sectioning. Heat generated would be sufficient to cause through-section melting for 0.5 micrometer thick sections assuming the worst possible case, namely that all heat went into the section without loss. Presence of a Type II pattern (large fracture pattern) is thought to be presumptive evidence against thawing.

  8. The cutting of metals via plastic buckling

    Udupa, Anirudh; Viswanathan, Koushik; Ho, Yeung; Chandrasekar, Srinivasan

    2017-06-01

    The cutting of metals has long been described as occurring by laminar plastic flow. Here we show that for metals with large strain-hardening capacity, laminar flow mode is unstable and cutting instead occurs by plastic buckling of a thin surface layer. High speed in situ imaging confirms that the buckling results in a small bump on the surface which then evolves into a fold of large amplitude by rotation and stretching. The repeated occurrence of buckling and folding manifests itself at the mesoscopic scale as a new flow mode with significant vortex-like components-sinuous flow. The buckling model is validated by phenomenological observations of flow at the continuum level and microstructural characteristics of grain deformation and measurements of the folding. In addition to predicting the conditions for surface buckling, the model suggests various geometric flow control strategies that can be effectively implemented to promote laminar flow, and suppress sinuous flow in cutting, with implications for industrial manufacturing processes. The observations impinge on the foundations of metal cutting by pointing to the key role of stability of laminar flow in determining the mechanism of material removal, and the need to re-examine long-held notions of large strain deformation at surfaces.

The base of the cuttings were dipped in IBA solution for 10 seconds and then were staked in polyethylene tubes of 110 cm³, filled with organic substrate (Bioplant®. The irrigation of the seedlings was carried out by means of a nebulization system with a uniform flow rate of 7 L.h-1. After 40 days, were evaluated: percentage of survival, rooting percentage, percentage of roots observed at the lower end of the plastic tube, average number of roots, length of roots, presence of calluses, vigor and root dry matter. The results for the characteristics evaluated, with emphasis on survival, showed the highest averages were obtained at intermediate stakes, regardless of the dose of IBA. The highest rooting percentage, root number, length and dry mass of roots, in both types of cuttings was obtained with the highest dose tested of AIB (32,000 mg.L-1. Based on these results, it is concluded that the technique of cutting associated with application of plant growth regulators can be used for vegetative propagation of S. amazonicum.

    Energy Technology Data Exchange (ETDEWEB)

    Tani, Giovanni; Tomesani, Luca; Campana, Giampaolo

    2003-03-15

    In this paper, an analytical model for the evaluation of the melt film geometry in laser cutting of steels is developed. Using as basis, a previous model for kerf geometry estimation developed by the authors, with both reactive and non-reactive process gases, the film thickness and velocity were determined as a function of the kerf depth in the cutting plate. Two criteria were then adopted to predict the quality of the laser cutting operation: the first is based on a minimum acceptable value of the ejection speed of the melt from the bottom of the kerf, the second on the occlusion of the kerf itself due to an excess of molten material in the boundary layer at the kerf width. These criteria determined a feasibility region in the domain of the process and material variables, such as cutting speed, assistant gas pressure, laser beam power and material characteristics. These factors may be successfully used to build a process-planning tool for parameters optimisation and setting, in order to achieve a satisfactory process quality. The model response is in excellent agreement with the feasibility regions reported from experimental data by various authors and demonstrates a relationship between the occurrence of dross adhesion and the two different mechanisms predicted for such a phenomenon were: unsatisfactory ejection speed of the melt film from the bottom of the kerf and occlusion of the kerf.

  4. Automatic Generation of Minimal Cut Sets

    Directory of Open Access Journals (Sweden)

    Sentot Kromodimoeljo

    2015-06-01

    Full Text Available A cut set is a collection of component failure modes that could lead to a system failure. Cut Set Analysis (CSA is applied to critical systems to identify and rank system vulnerabilities at design time. Model checking tools have been used to automate the generation of minimal cut sets but are generally based on checking reachability of system failure states. This paper describes a new approach to CSA using a Linear Temporal Logic (LTL model checker called BT Analyser that supports the generation of multiple counterexamples. The approach enables a broader class of system failures to be analysed, by generalising from failure state formulae to failure behaviours expressed in LTL. The traditional approach to CSA using model checking requires the model or system failure to be modified, usually by hand, to eliminate already-discovered cut sets, and the model checker to be rerun, at each step. By contrast, the new approach works incrementally and fully automatically, thereby removing the tedious and error-prone manual process and resulting in significantly reduced computation time. This in turn enables larger models to be checked. Two different strategies for using BT Analyser for CSA are presented. There is generally no single best strategy for model checking: their relative efficiency depends on the model and property being analysed. Comparative results are given for the A320 hydraulics case study in the Behavior Tree modelling language.

    2018-06-01

    The femtosecond laser ablation process for cutting thin aluminoborosilicate glass sheets of thickness 100 μm was investigated with emphasis on effective cutting speed (Veff) and mechanical strength of diced samples. The process parameters including the laser fluence (F), overlap ratio (r) of the laser beam and polarization direction were varied at a fixed pulse repetition rate f = 1 kHz to find the optimal process condition that maximizes Veff and edge strength. A three-point bending test was performed to evaluate the front-side and back-side bending (edge) strength of the laser-cut samples. Veff was proportional to F unless r exceeded a critical value, at which excessive energy began to be delivered at the same spot. The front-side edge strength was bigger than the back-side strength because of the back-side damages such as chipping. Good edge strength, as high as ∼280 MPa (front-side) and ∼230 MPa (back-side), was obtained at F = 19 J/m2, r = 0.99, with laser polarization vertical to the cutting path.

  7. A pastoral evaluation and responses to the challenge of spiritual insecurity in African pastoral ministry and Christianity

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available This article argues that there is a form of Christian syncretism operating in African Christians� use of traditional African powers to address their spiritual insecurity challenges that arises from their former traditional African worldview of spiritual powers. It provides an overview description of the nature of the spiritual insecurity which still grips African Christians by delving into the traditional African worldview of spiritual powers (such as the notions of a Supreme Being, lesser divinities, spirits and ancestors and the centrality of traditional powers such as diviners in addressing this insecurity. After underscoring the aforementioned, this article proceeds to demonstrate three predominant views proposed by theological scholars as a response to the spiritual insecurity of African Christians. The first stance calls African Christians to discontinue with anything that is linked to traditional African spiritual worldview because Christianity entails a complete new ontological being. The second stance disapproves African Christians� reliance on traditional African powers and then proceeds to argue that Christian ministry should identify positives within the African spiritual world system and worldview that is useful and can be imported for use in contextualising the gospel. The third position advocates for Christians� continual reliance on traditional African spiritual powers in addressing their African contextual needs. In doing this, the weaknesses and strengths of these approaches are established with the view to outline an alternative biblical theological basis to ensure biblical Christianity in the challenging African contexts of spiritual insecurity. This article concludes by drawing from various theological responses to the spiritual insecurity of African Christians to ensure Christian ministry that is thoroughly biblical and contextual in African Christianity.Intradisciplinary and/or interdisciplinary implications: This

    The possibility of making quick checkings of the inhomogeneities of turning materials with radioactive wear measurements has been tested. After activation analysis of the long-lived radioisotopes of cutting tools made of hard metal a method for loss-free collection of the turnings has been developed. The detection limit of the abrasion is about 10 -8 g, the measuring times are 5-10 minutes. Special radiation protection measures are not necessary. An analysis of the abrasion showed that at the beginning of cutting the amount of cobalt is 6 times higher than in the normal composition of the used cutting tools. (author)

  14. Remotely controlled cutting techniques in the field of nuclear decommissioning. Overview of effectively applied thermal cutting methods

    International Nuclear Information System (INIS)

    Bienia, H.; Klotz, B.

    2008-01-01

    This article describes 3 thermal cutting technologies that are effectively used in nuclear decommissioning projects: the autonomous flame cutting, the plasma arc cutting and the contact arc metal cutting. The autonomous flame cutting technology is based on a high pressure oxygen jet oxidizing the material in a small kerf. Not all metal types are appropriate for this technology. The plasma arc cutting, in contrast to the previous technology, uses an electronically induced plasma arc to melt a kerf in the material. Inside the plasma arc temperatures up to 30.000 K exist, so in theory, this temperature is sufficient to cut all materials. Contact arc metal cutting is a new thermal cutting technology for under-water cutting works. Here, a carbon blade cuts the components. An electric arc between the cutting blade and component melts a kerf into the material easing the cutting. This technology allows the cutting of complex structures with hollows. The applications in nuclear facility dismantling of these 3 cutting technologies and their limits are reported and their requirements (staff, investment) listed in a table. (A.C.)

    Ductile cutting are most widely used in fabricating high-quality optical glass components to achieve crack-free surfaces. For ultra-precision machining of brittle glass materials, critical undeformed chip thickness (CUCT) commonly plays a pivotal role in determining the transition point from ductile cutting to brittle cutting. In this research, cutting characteristics in nanometric cutting of BK7 and fused silica glasses, including machined surface morphology, surface roughness, cutting force and specific cutting energy, were investigated with nanometric plunge-cutting experiments. The same cutting speed of 300 mm/min was used in the experiments with single-crystal diamond tool. CUCT was determined according to the mentioned cutting characteristics. The results revealed that 320 nm was found as the CUCT in BK7 cutting and 50 nm was determined as the size effect of undeformed chip thickness. A high-quality machined surface could be obtained with the undeformed chip thickness between 50 and 320 nm at ductile cutting stage. Moreover, no CUCT was identified in fused silica cutting with the current cutting conditions, and brittle-fracture mechanism was confirmed as the predominant chip-separation mode throughout the nanometric cutting operation.

    Anemia in children is a public health issue, and the current strategies include treatment and iron supplementation, but their level of adherence or compliance is unknown. To consider the adherence to multiple micronutrient powders and the associated factors. Epidemiological study of active surveillance through sentinel facilities in 2,024 children aged 6 to 35 months treated in health facilities of the Ministry of Health of Peru, from October to December 2014. Household visits were conducted in which counting of multiple micronutrient powders was applied and determined an adherence of consumption ≥ 90% envelopes, besides a form on the associated factors (anemia knowledge, iron-rich food, side effects, dosage regimen, drugs used, and motivation) was applied. Descriptive statistics, χ² test, Odds Ratio with a 95% confidence interval (CI), and binary logistic regression or adjusted Odds Ratio (aOR) were used. Of all, 79.1% participants were aged 6 to 23 months; 75.9% received multiple micronutrient powders; and the adherence was equivalent to 24.4% (95%CI 22.3 - 26.6). The factors: continue supplementation (OR = 3.5; 95%CI 1.7 - 7.5); no nausea (OR = 3.0; 95%CI 2.0 - 4.3); no use of antibiotics (OR = 2.5; 95%CI 1.7 - 3.6); and intention to continue treatment (OR = 2.3; 95%CI 1.3 - 4.1) were associated with adherence. The variables: thought of continuing treatment (aOR = 2.6; 95%CI 1.1 - 6.1); presence of side effects, but no discontinuation of the treatment (aOR = 2.5; 95%CI 1.4 - 4.3); no use of antibiotics (aOR = 2.0; 95%CI 1.1 - 3.4); and belief that not only drugs cure anemia (aOR = 1.6; 95%CI 1.0 - 2.6) were associated in the multivariate analysis. There was a low prevalence of adherence to a demanding cut-off point (≥ 90% of envelopes of multiple micronutrient powders), and the associated factors are associated with absence of infections, side effects, and mother's beliefs.

    We introduce test tube systems based on operations that are closely related to the splicing operations, i.e. we consider the operations of cutting a string at a specific site into two pieces with marking them at the cut ends and of recombining two strings with specifically marked endings. Whereas in the splicing of two strings these strings are cut at specific sites and the cut pieces are recombined immediately in a crosswise way, in CR(cutting/recombination)-schemes cutting can happen independently from recombining the cut pieces. Test tube systems based on these operations of cutting and recombination turn out to have maximal generative power even if only very restricted types of input filters for the test tubes are used for the redistribution of the contents of the test tubes after a period of cuttings and recombinations in the test tubes. 10 refs.

    2017-06-01

    In addition to a high spatial resolution and well characterised dose response, one of the major advantages of radiochromic film as a dosimeter is that sheets of film can be cut into pieces suitable for use as calibration films, and for in vivo and phantom measurements. The cutting of film is typically done using scissors or a guillotine, and this process can be time-consuming, limited in precision, requires extensive handling and does not allow holes to be cut from the film without cutting from an existing edge. This study investigated the use of a Brother ScanNCut hobby cutting system for EBT3 film preparation. The optimal operating parameters (blade size, pressure, speed) that resulted in precise cuts with minimal delamination at cut edges were identified using test cutting patterns. These parameters were then used to cut a large film insert for a stereotactic head phantom for comparison against an insert cut with scissors. While the hobby cutting system caused a wider region of delamination at the film edge (1.8 mm) compared to scissors (1 mm), the hobby cutting system was found to be able to produce reproducible cuts more efficiently and more accurately than scissors. The use of the hobby cutting system is recommended for complex phantom inserts (containing sharp corners or holes for alignment rods) or in situations where large numbers of film pieces need to be prepared.

  20. Investigation of Cutting Quality of Remote DOE Laser Cutting in 0.5 mm Stainless Steel

    Villumsen, Sigurd Lazic; Kristiansen, Morten

    It has previously been shown that the stability of the remote fusion cutting (RFC) process can be increased by modifying the intensity profile of the laser by means of a diffractive optical element (DOE). This paper investigates the quality of remote DOE cutting (RDC) conducted with a 3 kW single mode fiber laser in 0.5 mm stainless steel. An automatic measurement system is used to investigate how the travel speed, focus offset and angle of incidence effect the kerf width and kerf variance. The study shows that the RDC process has a very low kerf width variance, and that the kerf width decreases with cutting speed. Furthermore, selected etched samples show a significant increase in the perpendicularity of the cuts when compared to RFC. Also, on average, the depth of the layer of molten material for RFC is 83% deeper than for RDC.

Content analysis was employed to identify health promoting contents in the messages posted between November 2013 and February 2014. A total of 105 messages were published on the topic of interest (37 from Peru and 68 from Brazil). In both cases, most messages focused on individuals, addressing the change or adoption of personal behaviors relating to the prevention and detection of HIV - 34 messages (50.0%) for Brazil and 17 (45.9%) for Peru. Twenty-one (30.9%) messages with a structural emphasis were published by Brazil and 14 (37.8%) by Peru, addressing the context of health care system organization, including HIV/ AIDS health policies, available services, access to HIV testing and initiatives to promote testing. Hybrid messages, including both emphases, were less frequent: 13 (19.1%) for Brazil and six (16.2%) for Peru. Health promoting contents were identified in hybrid messages, which provided resources to expand the understanding of individuals about the susceptibility to AIDS.

    High-power laser cutting is extensively used in many industrial applications. An important weakness of this process is the formation of striations, i.e. regular lines on the cut surface, which lowers the quality of the surfaces produced. The elimination of striation formation is thus of considerable importance, since it could open a variety of novel high-precision applications. This study presents the initial results of a laser cutting study using a 1 kW single-mode fibre laser, a relative newcomer in the field of laser metal cutting. Striation-free laser cuts are demonstrated when cutting 1 mm thick mild steel sheets. (orig.)

    An edge dominating set $F$ of a graph $G=(V,E)$ is an \\textit{edge cut dominating set} if the subgraph $\\langle V,G-F \\rangle$ is disconnected. The \\textit{edge cut domination number} $\\gamma_{ct}(G)$ of $G$ is the minimum cardinality of an edge cut dominating set of $G.$ In this paper we study the edge cut domination number and investigate its relationships with other parameters of graphs. We also introduce the properties edge cut irredundance and edge cut independence.

    The cutting resistance curve is the most useful tool for reflecting the overall cutting performance of a cutting machine. The cutting resistance curve is influenced by many factors such as the pick structure and arrangement, the cutter operation parameters, coal quality and geologic conditions. This paper discusses the use of fractal geometry to study the properties of the cutting resistance curve, and the use of fractal dimensions to evaluate cutting performance. On the basis of fractal theory, the general form and calculation method of fractal characteristics are given. 4 refs., 3 figs., 1 tab.

    Three Hundred Sixty Degree Feedback systems, while popular in business, have been less commonly implemented in local public health agencies. At the same time, they are effective methods of improving employee morale, work performance, organizational culture, and attainment of desired organizational outcomes. These systems can be purchased "off-the-shelf," or custom applications can be developed for a better fit with unique organizational needs. We describe the City of Milwaukee Health Department's successful experience customizing and implementing a 360-degree feedback system in the context of its ongoing total quality improvement efforts.

    After one hundred fifty years of drilling first commercial petroleum wells that led to the intensive use of liquid fuels to move transport vehicles, we are arriving at the peak of the world-wide petroleum reserves. Yet, we still have a good portion for spending, with the hope that the consequences will be better than in the first part, which has implied several wars and deteriorations of the environment. This assay brings a review about the history of fossil fuels and with the prospective of the emergent energetic alternatives, placing emphasis on bioenergy as an alternative for the transition between the actual combustion age and the new age of clean energy.

    Full Text Available The Great War has featured regularly in Michael Longley’s poetry, for personal, family, aesthetic and political reasons. His collection published in 2011 under the title A Hundred Doors contains a number of poems relating to his father and the so-called War Poets, in connection with others in which love and nature, life and death are also dominant themes. This article will show how, as elsewhere in his poetry, everything is interrelated, “the nature poetry”, in Longley’s words, “fertilizing the war poetry”.

  15. Respiration rate and ethylene production of fresh cut lettuce as affected by cutting grade

    Full Text Available For designing optimal polymeric films for modified atmosphere packaging of whole heads as well as for minimally fresh processed (fresh-cut Iceberg lettuce ‘Coolguard’, the effect of several cutting grades on respiration rate (RR and ethylene production at 5ºC was studied. According to common industrial practices cutting grades less than 0.5 cm, between 0.5 and 1 cm, and 2 cm length were selected. Results from four experiments were compared to those obtained for whole heads in which a homogenous range of 6 to 8 ml CO2 kg-1 h-1 in RR was found. Compared to whole heads, in fresh-cut lettuce the RR was 2-fold higher. The lowest cutting grade showed the highest respiration rate, and no significant differences in RR among lettuce pieces of intermediate and the highest grades were found. No ethylene production was detected in whole heads, while in minimally processed lettuce pieces only traces were found. For avoiding risks of anaerobic respiration and excessive CO2 levels within packages containing fresh-cut lettuce pieces lower than 0.5 cm length, films with relatively high O2 permeability like standard polypropylene or low-density polyethylene must be selected.;

    Most output parameters in machining, such as cutting forces, temperatures, strains and the work-hardening of the chip material, are directly related to the chip formation process. The characteristics of machining processes can be well understood if the forces and strains during chip formation are known. In this research a lathe tool dynamometer was used to measure cutting forces involved in machining of Steel 1045 and Aluminum 2219 T62. High Speed Steel (HSS), cutting tools with positive and negative rake angles were used. It was observed that more cutting forces are experienced by the cutting tool with positive rake angle as compared to the forces experienced by the cutting tool with negative rake angle. For steel 1045 the cutting forces using positive rake angle cutting tool were much higher. This suggested that for harder materials using a negative rake angle is more suitable for cutting. (author)

    Skin segmentation is widely used in many computer vision tasks to improve automated visualiza-tion. This paper presents a graph cuts algorithm to segment arbitrary skin regions from images. The detected face is used to determine the foreground skin seeds and the background non-skin seeds with the color probability distributions for the foreground represented by a single Gaussian model and for the background by a Gaussian mixture model. The probability distribution of the image is used for noise suppression to alle-viate the influence of the background regions having skin-like colors. Finally, the skin is segmented by graph cuts, with the regional parameter y optimally selected to adapt to different images. Tests of the algorithm on many real wodd photographs show that the scheme accurately segments skin regions and is robust against illumination variations, individual skin variations, and cluttered backgrounds.

  19. Prototype arc saw design and cutting trials

    A program was initiated to develop the arc saw as a tool capable of removing the end fittings from spent nuclear fuel bundles. A special arc saw for this purpose was designed, installed at the Pacific Northwest Laboratory and satisfactorily operated to remove end fittings from simulated, nonradioactive fuel bundles. The design of the arc saw included consideration of the cutting environment, power supply size, control equipment, and work piece size. Several simulated fuel bundles were cut to demonstrate that the arc saw met design specifications. Although the arc saw development program was curtailed before significant performance data could be collected, tests indicate that the arc saw is a good means of cropping spent fuel bundles and is well suited to remote operation and maintenance

    We prove several geometric theorems using tools from the theory of convex optimization. In the Riemannian setting, we prove the max flow-min cut (MFMC) theorem for boundary regions, applied recently to develop a ‘bit-thread’ interpretation of holographic entanglement entropies. We also prove various properties of the max flow and min cut, including respective nesting properties. In the Lorentzian setting, we prove the analogous MFMC theorem, which states that the volume of a maximal slice equals the flux of a minimal flow, where a flow is defined as a divergenceless timelike vector field with norm at least 1. This theorem includes as a special case a continuum version of Dilworth’s theorem from the theory of partially ordered sets. We include a brief review of the necessary tools from the theory of convex optimization, in particular Lagrangian duality and convex relaxation.
