In the Physics Department of the Sciences Faculty of the Universidad Nacional Autonoma de Mexico (UNAM) exist at least 3 sites where radioactive sources and generating equipment s of ionizing radiation are managed: The Modern Physics Laboratory, the Radiological Analysis of Environmental Samples Workshop and the Collisions Workshop; the first of them has two neutron sources, in addition to other emitted sources of gamma and beta radiation. The neutron sources are of Americium 241-Beryllium and other of Californium-252 which have been operated outside of the control of the Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS) that is the regulator organ in Mexico in nuclear matter, because the Operation License No. 183/85, with file number 657 that protected them, lost their validity from August 13, 1987 (25 years behind), what motivated to that the CNSNS assured them. Later to the closing of the Radiological Analysis of Environmental Samples Workshop was believed that a Barium-133 source had been extracted in an illegal way; an investigation realized by the CNSNS determined that the radioactive source was always inside of the detection systems and radiation measurement, for what this source was never lost. In the Collisions Workshop operated an Experimental Accelerator of Particles that the CNSNS prohibited its operation for not having the corresponding license. These examples can be considered as bad practices of radiological protection that should be pointed out to eradicate their promotion and to avoid this way the exposure to the radiation of the occupational exposed personnel and people in general, being also avoided dose of unnecessary radiation. The Instituto Federal de Acceso a la Informacion Publica y Proteccion de Datos (IFAI) in Mexico was a key factor to obtain the information that allowed the realization of this work that was carried out in the Sciences Faculty of the UNAM.

The concern of the corrosion in buried pipes has increased with the course of time, the aging of the mechanical protection of the piping, results in defects in the coating, exposing the metal to the corrosive ground, in which the piping is lodged. If suitable levels of cathodic protection do not exist, the corrosion phenomenon in these defects is presented originating unexpected faults in the piping, increasing the costs of maintenance and repair, as well as the diminution in the safety during the operation, as much for the workers as for the communities near the installation of ducts. The technique of Direct Current Voltage Gradient (DCVG), besides locating the defects of the coating in a buried pipe (which are corrosion potential sites), determines corrosion status of the defects and its severity as far as the consumption of protection current that each of these absorbs. Nevertheless, all this information acquires a greater relevance, when it is correlated with the operating conditions of the cathodic protection systems, to be able to emit recommendations that lead to the mitigation or eradication of the corrosion problems, together with a good operation of the protection systems. [Spanish] La preocupacion por la corrosion en tuberias enterradas ha ido en aumento con el transcurso del tiempo, debido al envejecimiento de la proteccion mecanica de las tuberias, el cual da como resultado defectos en el recubrimiento, dejando expuesto el metal en suelo corrosivo, en el que se encuentra alojada la tuberia. Si no existen niveles de proteccion catodica adecuados, se propicia el fenomeno de corrosion en estos defectos, originando fallas inesperadas en las tuberias, incrementando a su vez los costos de mantenimiento y reparacion, asi como la disminucion en la seguridad durante la operacion, tanto para los trabajadores como para las comunidades cercanas a las instalaciones de ductos.

Today in day is difficult to imagine the development of the medical practices in the diagnosis and treatment of diverse illnesses without the use of the ionizing radiations. In spite of the diffusion and application of these practices, the patients and the public in general don't have full conscience of like the procedures are carried out and the risks that these involve. For it diverse international and national organizations in the last years recommend to include in the programs of radiological protection, all the information that should be given to the patients and the one public that attend as users to the medical institutions to undergo to procedures that imply the use of the ionizing radiations. In Cuba a growing and quick tendency exists to the introduction of nuclear techniques for medical ends, however paradoxically the relative aspects to the communication to the patients and the public in general about the risks of the procedures to that they will be subjected and in consequence on the measures to minimize them is not adequate. Keeping in mind the above-mentioned, specialists of national centers linked to the control and consultant ship in the topics of radiological protection in the medical practices that use ionizing radiations, they worked in the country in the design of an information system that should contribute to elevate the population's culture before the mentioned aspects. The present work describes the structure of this system in function of the different medical attention levels of our national health system. Additionally it exposes the development of a package of varied informative and training tools among those that are folding, posters, guides, instructions, CD Show that its approach general and specific aspects of the uses and risks of medical practices in nuclear medicine, radiodiagnostic and radiotherapy directed so much to health professionals, patients as public in general.

A national programme on radiation protection of patients can only be effective and sustainable if there is a joint effort between the regulatory body and the health authorities, and a cooperation with educational institutions, professional bodies and representatives of the industry. The regulatory body needs to promote a strategy of cooperation, and to identify obstacles that may prevent compliance with regulatory requirements and to address them. Not of least is the need for a continuous self-evaluation on the efficacy of the programme. Radiation safety of the patients is a responsibility of the users of the radiation sources involved in diagnostic and treatment. In particular, they are responsible for compliance with regulatory requirements. But safety depends also on aspects that are beyond the capabilities of those authorized to conduct practices. These aspects include educational programmes and institutions to implement them, calibration facilities, national protocols, professional bodies for the establishment of reference levels and contributions from the industry. Neither the users nor the regulatory body alone can achieve that these elements are in place. It needs a network of institutions and cooperation arrangements that involve educational and health authorities, laboratory facilities, professional bodies and the industry. A national programme has to include a strategy of cooperation, identification of obstacles that may prevent compliance with regulatory requirements and address them. Not of least is the need for a continuous self-evaluation on the efficacy of the programme. A group of regulatory agencies belonging to the Ibero American Forum of Nuclear and Radiation Regulatory Agency have exchanged experiences, lessons learned and good practices over three years. This exchange included extensive collaboration with the health authorities. The result of this work is this document containing a self-evaluation approach for the regulatory programme on

observacion cientifica, ha demostrado su eficacia en la modernizacion de cientos de procesos industriales, comerciales, de comunicacion y de servicios, asi como de los materiales y metodologias utilizadas para la proteccion de diversos equipos y procesos; desde la proteccion en sistema y equipos en alta tension hasta sistemas que manejan muy baja energia, entre los que incluyen electronicos y digitales. Sin embargo, existen leyes fundamentales como la ley de Ohm, la ley de gravedad o la ley universal de gases que, pese a que fueron descubiertos hace muchos anos, siguen vigentes y su validez proporciona elementos invaluables para el desarrollo de nuevos metodos, procesos y desarrollos tecnologicos. Uno de los casos mas relevantes que amalgama la aplicacion de criterios fundamentales y el desarrollo de nuevas tecnologias y su aplicacion en los llamados dispositivos de proteccion no convencionales lo constituye la proteccion contra el efecto de las tormentas electricas en edificios y estructuras. La aplicacion de estos dispositivos en el ambito mundial ha generado escepticismo de una gran parte de la comunidad cientifica, reacciones diversas entre los usuarios y un postura firme por parte de los fabricantes para que dichas tecnologias sean incluidas en normas internacionales. El objetivo de este articulo es ofrecer al lector la informacion basica sobre los inicios de la proteccion, la evolucion que los metodos de proteccion contra las tormentas electricas han tenido desde el siglo XVIII, la aplicacion de los criterios fundamentales de proteccion en estructuras o edificios modernos y su contenido, asi como la situacion que prevalece actualmente en los comites de las diversas organizaciones normativas nacionales e internacionales en lo referente a la inclusion de las nuevas tecnologias en las guias de diseno.

The objective of Radiological Protection is to gurantee that neither people, be they workers or members of the public, or the environment are exposed to radiological risks considered by society to be unacceptable. Among the various resources available to meet this objective is Research and Development (R and D), which is carried out in three areas: I. Radiological protection of persons: (a) knowledge of the biological effects of radiations, in order to determine the relationship that exists between radiation exposure dose and its effects on health; (b) the development of new personal dosimetry techniques in order to adapt to new situations, instrumental techniques and information managmenet technologies allowing for better assessment of exposure dose; and (c) development of the principle of radiological protection optimisation (ALARA), which has been set up internationally as the fundamental principle on which radiological protection interventions are based. II. Assessment of environmental radiological impact, the objective of which is to assess the nature and magnitude of situations of exposure to ionising radiations as a result of the controlled or uncontrolled release of radioactive material to the environment, and III.Reduction of the radiological impact of radioactive wastes, the objective of which is to develop radioactive material and waste management techniques suitable for each situation, in order to reduce the risks assocaited with their definitive managmenet or thier release to the environment. Briefly desribed below are the strategic lines of R and D of the CSN, the Electricity Industry, Ciemat and Enresa in the aforementioned areas. (Author)

The laws on radiological protection have special characteristics. They can exist laws that regulate dangerous activities that will be also applicable, if it corresponds to the activities that involve radioactive materials. But a law of radiological protection should exist. It foresees the existence of an appropriate regulatory body and specialized institutions, definitions, infractions and sanctions then the respective regulations will be elaborated for the different applications. The objective is to contribute to the development of the nuclear energy in the country and to provide the regulatory basis that assures a reasonable security for radioactive installations. The essential objectives of these laws are: 1. to establish the legislative framework for the development and employment of nuclear energy, without risks, according with treaties and conventions that the countries have approved. 2. To fix the fundamental principles and the conditions of their setting in practice allowing to a specific regulation determining application procedures. 3. To create a structure of regulation of enough authority to be able to control and to watch over in an effective way the authorized activities 4. To guarantee an appropriate financial protection against the derived damages of accidents or nuclear incidents. (author)

The cancer incidence in the world has been increased with the course of the time. Fifty percent of the patients receive radiotherapy, as much in the initial treatment, as in the recurrence cases or palliatives. At the moment is considered that in 1998 there were 2,500 teletherapy machines in operation in the countries in development and for the year 2015 will be necessary 10,000. In Mexico the use of these teletherapy units goes back to the year of 1956, when the effort of the Dr. Noriega Limon was consolidated with the installation of the first teletherapy unit with a cobalt 60 source in the National Medical Center of the IMSS. In the same decade the operation began of the Calibration Secondary Center located in the facilities of the General Hospital of Assistance and Health Secretary where a group of seven physicists began in the metrology techniques. Also the national authority in matter of the ionizing radiations use appears and promulgates the first Law in Nuclear Matter. The application has extended in the country, as well as other techniques that have gone incorporating for the cancer treatment. Such as: the brachytherapy, the stereo ataxia and the ophthalmic applicators. In the current application of the radiotherapy several factors are interrelated that have for objective that the dose to the workers and the public is as low as reasonably it can be achieved and that the patient receives the dose prescribed by the medical treatable in the organ or tissue and in the orderly quantity with the minor damage for the healthy tissues. To reach all this, it is necessary to have equipment s, systems, procedures, personal and standards that improve their quality in a gradual but firm way, also the good communication and comprehension among authorities are fundamental for this noble task.

Full Text Available Las redes de distribución han sido diseñadas para que la potencia fluya en una sola dirección. La introducción de la Generación Distribuida (GD hace que esta consideración ya no sea válida. Esto traerá nuevos retos para la operación y el diseño de la red. Una de las áreas críticas más afectadas que existe es la de las protecciones eléctricas. En este trabajo se hace el estudio de cómo se afectan los ajustes de las protecciones eléctricas al trabajar con generación distribuida en una red de distribución. Para ello se simuló una red con la ayuda del software denominado PSX. Se conectó generación en distintos lugares, de diferentes capacidades y tipos. Se calcularon los niveles de cortocircuitos en los distintos escenarios para los cuales fueron ajustadas las protecciones. Se obtuvieron un conjunto de resultados interesantes, los cuales pueden conducir a nuevas estrategias en lo que respecta a estos equipos.The distribution networks have been designed so that the power flows in a single direction. When the Distributed Generation is introduced this consideration is no longer valid. Distributed Generation will bring new challenges for the operation and the design of the network. One of the most critical areas affected is the electric protection. This paper discusses issues of how the adjustments of the electric protection are affected when the Distributed Generation is introduced in a distribution network. For this purpose, the network was simulated with the help of the software named PSX. The generation was connected in different places, with different capacities and types. The levels of short circuits were calculated in the different scenarios in which the protections were adjusted. A set of interesting results was obtained, which can lead to new strategies in what concerns to these protections.

The Government in Paraguay approved by Decree Law 10754, dated October 6, 2000, its National Regulation on Basic Safety Standards for Radiation Protection and the Safety of Radiation Sources, based on the IAEA Safety Standards 115. The primary goal of Patient Protection is to ensure that both Regulatory Authorities and all Responsible parties in Medical Practices observe procedural process in conducting their responsibilities on regulatory and administrative affairs. On one side the Government, 'Department de Proteccion Radiologica', under the Health Ministry and Comision Nacional de Energia Atomica, and on the other side, the medical practitioner who prescribes or conducts diagnostic or therapeutic treatment, both ensure that the exposure of patients be the minimum. This document describes how the Regulatory Authorities intend to implement this recent act and on the other hand take the advantage of this Conference to understand better this subject, especially on the following subjects: essential requirement for licensing, inspection and enforcement programme in the country's capital and in the interior, where there are more difficulties; workers and medical training and lessons learned applying to developing countries.

This presentation sharing experiences which correspond to the nuclear power plant of Laguna Verde. This nuclear power plant is located at level 2 of four possible, in the classification performance of the World Association of Nuclear Operators (WANO), which means the mexican nuclear power plant is classified in terms of its performance indicators and above the average achieved by their counterparts americans and canadians. In the national context, the nuclear power plant of Laguna Verde has also been honored with several awards such as the National Quality Award, the Clean Industry Certificate, the distinction of Environmental Excellence and others of similar importance. For the standards of WANO, the basic idea is that there are shortcomings in one of nuclear power plant concern to all partners. The indicators used for the classification will always go beyond more compliance with regulations, which are assumed, and rather assume come or a path to excellence. Among the most important indicators are: the collective dose, the percentage of areas declared as contaminated, the number, type and tendency of contamination personal cases, the number of dosimetry alarms, the number of unplanned exposures, loss control of high radiation areas and the release of contaminated material outside the restricted areas. Furthermore, as already indicated, nuclear power plants are of special care situations, such as, carrying out work in areas with radiation fields of more than 15 mSv h{sup -1}, the movement of spent fuel in the reload floor. The consideration of the minimum total effective dose equivalent as a criterion for prescribing tools that reduce exposures, but may increase the external cases of contaminated casualties, the experience in portals such as workers subject to radiology, where exposure in industrial radiography, and so on. Special mention deserve the conditions generated during fuel reload stops, which causes a massive personnel movement, working simultaneously on several fronts, the number of dosimetry transactions, increases up to 30 times the normal operation, and so on. For these reasons during the reloads, the electronic dosimetry system and the monitoring system output contamination staff becomes critical systems whose functioning must be ensured to avoid becoming a bottleneck. Reloads must also be planned for a perfect manning of critical supplies such as clothing and protection accessories against contamination. (Author)

Iberdrola Ingenieria y Consultoria (Iberinco) has developed some computer applications based in New Technologies, Virtual Reality and Multimedia, with the aim to optimise the formation and training of professionally exposed workers as well as to inform the public. The use of the new technologies could be an important help for the workers training. Virtual Reality Projects developed by Iberinco are: a) CIPRES: Interactive Calculations of Radiological Protection in a Simulation Environmental and, b) ACEWO: Workers Control Access to Nuclear Power Plants, virtual Reality could be directly applicable to several aspects related with Radiological Protection Training, for example. An application that workers could used to learn the main aspects of Radiological Protection related with: a) Physical concepts, b) Regulations, c) Use of protective clothing, d) Access into and exit out controlled areas, e) ALARA criterion. An examples is the project ACEWO. A training program based on Virtual Reality systems with simulations of procedures in which the operators could receive high doses. In this way, the operation time and dose could be minimised according to the ALARA criterion owing to the ability of repeating the exercise, or the work, as many times as be necessary, like project CIPRES. Iberinco has been developed an educational CD multimedia on nuclear energy and the protection measures foreseen in the emergency plans for the Spanish Civil Protection Agency, with the aim of being distributed to all the schools placed near a nuclear power plant.

This plan of monitoring radiological environmental routine fits on environmental policy of CNEA, satisfying national and international recommendations for licensed facilities. Sampling matrices are related to direct routes of exposure: air and water (river, lake, sediments, drinking water). Soil samples are also analyzed for having integrated matrices. They are considered as minimum three points of measurement: a white point (water or winds up), a point of maximum (water or winds down) and a point corresponding to the location of the individual representative or a point of public interest. Measurements in air estimate KERMA rate with thermoluminescent dosimeters, bi-monthly, and concentrations of particulate material and aerosols. For water samples (monthly), soil and sediments (quarterly), radionuclides that have download limits are analyzed, according to its importance in the dosages produced in the representative individual. In these cases artificial radionuclides using gamma spectrometry, beta total and Sr-90 by radiochemical techniques if the value of total screening (1 Bq/L) is exceeded. Foods are not included because no possible matrices were detected, either by their distance. by located not predominant wind direction. They are however still looking for milk producers that fulfills the minimum requirements.The data collected are compared with environmental baselines to set trends that might point to future significant changes in the environment during the life of the facilities. So far it was not observed significant differences with respect to baseline values.

Operators in Nuclear Power Plants can receive high doses during refuelling operation. A training program simulating refuelling operations will be useful to reduce doses received by workers as well as to minimise operation time. With this goal in mind a Virtual Reality application is developed in the frame of CIPRES Project (Calculos Interactivos de Proteccion Radiologica en un Entorno de Simulacion - Interactive Calculations of Radiological Protection in a Simulation Environment), a RD project sponsored by IBERINCO and developed jointly by IBERINCO and the Nuclear Engineering Department of the Polytechnic University of Valencia. The Virtual Reality application requires the possibility of displaying doses, both instantaneous and accumulated, at all times during the operator training. Therefore, it is necessary to elaborate a database containing dose rates at every point of the refuelling plant. This database is elaborated from Radiological Protection Surveillance data measured throughout the plant during refuelling operation. To estimate doses throughout the refuelling plant some interpolation routines have been used. Different assumptions have been adopted in order to perform the interpolation and obtain consistent data. In this paper, procedures developed to elaborate the dose database for the Virtual Reality application are presented and analysed

Since its creation in 1967, the Argentine Radiation Protection Society (SAR) promotes all the radiation protection and nuclear safety aspects not only within the scientific, technical and academic areas, but also to general public. To fulfill this objective, SAR organised training and refresher courses, seminars and workshops on RP subjects. During 2002, SAR organised 7 basic and specialized courses regarding the uses of radioactive materials in industrial applications and the course on medical response in radiological accidents, that was attended by Argentine and other Latin American participants. The programmes of the courses are developed in compliance with the legal requirements and also considering specifics needs. In this paper, the characteristics of the courses are enunciated and basic statistics regarding courses and participants are presented. For the 2003 and 2004, SAR foresees the organisation of 18 courses per year and has the capacity to deliver other courses by request. all the courses are delivered in Spanish language. Based on this educational experience SAR consider a priority the inclusion, of a RP module in all the scientific graduate programmes to generate awareness on the importance of RP. Taking into account the migration of professionals to Europe and North America and the Globalization, SAR advocates the harmonization of RP syllabus to attain an international recognition. (Author)

The General Regulation of Radiation Safety, it clearly provides the classification, requirements and obligations of the various figures relating to a radiation protection system, i.e., the occupationally exposed personnel, the radiation safety responsible, the legal representative, the type of installation, etc. For new installations, the shieldings calculation should be contained in the analytical report with due consideration of factors, such as those surrounding the areas classification based on the occupation type, the work load of the equipment and others. The operation license involves requirements such as the Report and the Radiation Safety Handbook, the Emergencies Plan, the establishment of register levels, investigation and intervention, the way it is carried out medical surveillance of the occupationally exposed personnel, and the description of the protection mechanisms and detection instrumentation and radiation measurement. Deserves mention the case when high readings are recorded in the personal dosimeters, which must submit to an interrogation to the employee, you must determine if it is an incorrect reading to the service provider, you must perform a medical exam blood cell count with relevant to the dose determination, may eventually can lead to a cytogenetic study and the determination to do if confirmed an unexpectedly high dose. Moreover, the technology evolution also implies the development of adaptation measures. For example, the Intensity Modulated Radiation Therapy, which is an advanced high-precision radiotherapy that uses X-ray accelerators for computer-controlled radiation doses precisely to a malignant tumor or specific areas within the tumor, taking into account requires regard to equipment, and space and shielding, time and staff hours for treatment, personnel training, materials for making images (such as two-dimensional arrangements of integrated circuits or diodes, films or portal images), the attention given by the engineers of service, the validation of the treatment plan and quality control of the planning system and dosimetry parameters and mechanics.

The regulation antecedents in nuclear question in Mexico are placed in 1950, with the promulgation of {sup L}aw that declares national mining reserves the uranium deposits, thorium and the other substances of which obtains fissionable isotopes that can produce nuclear energy{sup ,} instrument that stipulated the control of uranium, thorium, as to its it indicated it name, and other fissionable substances, on the part of the state, although they were without a doubt the respective institutions, the National Commission of Nuclear Energy in 1955, and the one of the National Commission of Nuclear Safety and Safeguards (CNSNS) in 1979, those that allowed the development of a prescribed frame in the nuclear and radiological areas. One characteristic of the regulation in radiological protection is the variety in the authorities type that have incidence in the regulation, as a result of the different approaches with which it can be approached. For example, in Mexico normative instruments with content in radiological protection exist and are watched over the Health Secretary, who is oriented to the protection of the patient, their relatives and the medical body; Work and Social Welfare Secretary, with a labor approach; Communications and Transport Secretary, which regulates the transport of nuclear and radioactive materials; Finance and Public Credit Secretary, who regulates the import and export of radioactive materials; Environment and Natural Resources Secretary, which regulates the environment protection; Energy Secretary who has responsibilities inside of the {sup p}rescribed law of article 27 constitutional in nuclear matter{sup ;} and within the energy sector, the CNSNS that expedite and watch the fulfillment of normative in radiological protection and nuclear safety. In order to resist effects of on regulation; frequently inter institutional agreements are carried out in which the areas of monitoring are agreed by each authority. The regulation in radiological protection demands the attention in all the involved subjects, like for example the patient protection. The prescribed experience in Mexico indicates that the involved authorities only must demand faculties for whose fulfillment they have all the necessary resources, or on the contrary to guarantee that it was counted on the same. Also it is necessary to understand that when there are overlap of functions in the regulation must need to be a complete coordination between the involved authorities. (Author)

Currently there is a vast research about the harmful effects of the use of ionizing radiation in medical procedures and in recent years struck by the rapid innovation in imaging equipment, considerably increasing the radiation dose received both patients and professionals in the radiodiagnosis area, service having the greatest demand in our country. The main strategy that has so far is education, that is, to inform all those involved in managing ionizing radiation about the applications and risks associated with them. Generally it requires that all personnel occupationally exposed attesting a course of radiation protection. However, the high demand for this type of medical services and poorly trained staff, makes taking a classroom course for personnel occupationally exposed is complicated. So that in the Instituto Politecnico Nacional (IPN) we are designing a course in radiation protection to be implemented online, through the virtual platform Moodle in a first stage, and a massive open online course as the second stage so that can be carried by anyone interested in the subject, without having to appear in person. This will allows to reach the largest possible number of personnel occupationally exposed to just have a computer with internet access. (Author)

The nuclear medicine practice dates of the 1950 years, in this work the achievements reached as regards radiological protection are shown, although even lack a lot to make, the doses for the occupationally exposed personnel have decreased with lapsing of the years, thanks to the perception of the nuclear physicians to improve the administration techniques of the radioactive material, the decrease of administered activity and the unit doses use among the most remarkable advances. The changes in the equipment s technology to quantify the activity to administer, detection systems and image formation have demanded the development of the new professionals of the nuclear medicine that allows give protection to the patient. This improvement needs to consolidate with the appropriate normative development, the involved personnel qualification and the methods and procedures actualization to improve the protection of the occupationally exposed personnel, the public, the environment and the patient.

From its creation in 1967, the Argentine Radioprotection Society (SAR) has as basic purpose promoting all the aspects related with the radiological protection and the nuclear safety. Due to the great increment in the use of radioactive sources in diverse areas, soon it was evident for the SAR the importance and necessity to promote the knowledge of the radioprotection approaches between the users of radioactive sources and ionizing radiations in all its application fields, be these industrial, academic or doctors. From the year 2000, the SAR comes organizing in regular and periodical form basic and specialized courses about radiological safety of radioactive sources for industrial use and profile of oil wells, among others. In this work, the characteristics of the different dictated courses are described whose programs have been developed keeping in mind the requirements of the competent authorities of Argentina. Also, statistical information on the dictated courses and its participants is presented. The number of dictated courses was incremented from 6 (year 2000) up to 16 (year 2005), being also increased significantly the number of participants for course. The dictated courses are theoretical-practical, with a duration average of 20 hs. The educational body is constituted by specialists in the different topics with recognized experience. Its given to the participants notes and support material, as well as copies of the material presented to develop the course. When concluding the courses, its deliver to the participants certifies of attendance and/or approval, as it corresponds. In their headquarters the SAR has didactic facilities and specific equipment for the dictation of the courses. Also accounts with the easiness of dictating those courses outside of their headquarters. This is particularly advantageous for companies or organizations that are seated in points far from the main cities and they should qualify in radiological safety to the personnel but, by

In Peru, people who work with ionizing radiations must have an authorization (Individual License) as established in the Radiological Safety Regulations, which are the mandatory rules. The Technical Office of the National Authority (OTAN), which is the technical organ of the Peruvian Institute of Nuclear Energy (IPEN) in charge of controlling radiations within the country, grants the authorization after the candidate demonstrates that he/she knows the specific use of the technique using radiations, as well as the aspects related to safety and radiological protection. Since it was created in 1972, the Superior Center of Nuclear Studies (VSEN) from IPEN has carried out different training courses so that people can work safety with ionizing radiations in medicine, industry and investigation. The analysis of the radiological safety programs carried out by CSEN during the last 30 years, which allowed the training of more than 2200 people in the country and, at the same time, made possible the securing of the respective Individual License, is presented in this work. The courses, nuclear medicine, radiotherapy, industrial radiography, nuclear gauges gamma irradiator, etc..., are part of the continuous education program of CSEN. (Author)

The number of members had been increased. By the first month it had 117 members and by the end of the year 2002 it had already 179 members, 315 messages were send by then. By December 2007, there were 726 members from 28 countries mainly from Latin America: Argentina, Brazil, Bolivia, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay and Venezuela. There were also members from Austria, Canada, France, Israel, Italy, Portugal, Spain, Sweden, United Kingdom and United States. There have been distributed 2049 messages about Congress, courses and activities on national and international radiation protection and related issues which initially were in Latin American and the Caribbean. This has allowed diverse specialists that work in different themes to interchange experiences and information about subjects of common interest. This objective is the continuation of the spreading of activities that since 1991 and for 10 consecutive years had been made through the Bulletin 'Proteccion Radiologica', from which 65000 samples were published and distributed to specialists from 40 countries thanks to the support of the International Atomic Energy Agency (IAEA) and the Pan-American Health Organization (PAHO). This idea is complemented by the Web: www.radioproteccion.org. Interesting topics have been discussed in the network for example: Pregnancy and medical radiation, emergency response, occupational exposure, radiation protection responsibilities, lessons learned from accidental

This work describes the work done in the implementation of an educational project which aims the formation of technical-professional in radiation protection (RP) with official recognition in Mexico. The constant growth of business activities related to the use of radioactive material in industry, medicine and research has required the development and implementation of standardization by the regulatory authorities of our country. However the advance with regards to training of specialized personnel is reduced in comparison to current needs. in our country there is no technical personnel with studies recognised by the regulatory body in this specialty (RP), however quality assurance programs currently require an educational training that will help to meet the standards in the various activities that develop in the use and handling of sources and ionizing radiation generating equipment, reason why it was developed and implemented this educational project. Additionally induce and promote the need for the peaceful use of nuclear energy and ionizing radiation, at the national level is one more reason to implement the programme at upper secondary level, with the purpose to have knowledge related to the topic. The technical course has a duration of six semesters (three years), and currently there are two generations of graduating. The plan of study consists of the required disciplines for upper secondary level more plus those corresponding to technological training in radiological protection.

The Service of Personal Dosimetry of the External Dosimetry Laboratory of the Centro de Proteccion y Higiene de las Radiaciones - CPHR of Cuba works with an automatic RADOS TLD system and includes the surveillance of the doses of whole body and extremities for photon radiation. The work presents the results of the service in the period 2010-2011, showing data related to the number and distribution of workers monitored for areas. The levels of occupational exposure area analyzed using various indicators such as: annual average dose for areas, number of workers who receive annual doses greater than zero, distribution of workers by dose intervals, and others. These indicators are compared with previous periods and with the values published by the UNSCEAR. In general, the average annual dose for all areas was less than 1 mSv for whole body and 3 mSv for hands. The number of exposed workers experienced significant variation from one year to another, considerably decreasing from 60% to 12% of the total. The work presents an analysis of this behavior and highlights that the country guarantees the personal dosimetry to 100% of exposed workers and that the results of the occupational exposure are within the established requirements

To optimize times and movements in a reload project of nuclear fuel in a nuclear plant, where they are programmed more three thousand maintenance activities, modifications, monitoring and inspection in a smaller period to 30 days, and additionally to optimize the individual and collective dose in the same one, turn out to be important challenges where the used strategies must be accompanied of a deep knowledge of the installation in the radiological sense and of the spaces conceptualized in the time. The attention to the detail makes possible that the objectives are fulfilled. During the shutdown of reload 9 of Unit 2 (9RU2) of the nuclear power plant of Laguna Verde, the attention in detail applied in the critical points allowed a saving of dose of 0.7 Sv-person and one deviation of the goal of only +0.85% (smaller to 1% of the goal established like 2 challenge of Sv-person). Analysis of times, movements and training to develop skills in inspection activities in service that requires intervention in the external surface of the reactor vessel to examine the condition of welds, allowed reducing times of execution of 12 to 2 hours. Analysis of the environment and attention to the detail are techniques that allowed optimizing dose in 9RU2 and they were used in the project Power Increase. In this work the strategies of the surroundings and attention in detail applied in 9RU2 would appear and detail attention in the increase of power in the reload 13 Unit 1. (Author)

During the last years, electromagnetic emitters are more and more commonly used for therapeutic treatments in electrotherapy centers. This extended use has caused worries workers, who believe that microwave radiation radiation might have effects similar to those induced by radioactivity, even if the only effects recognised by international regulatory bodies concerning microwave exposure of humans are those of thermal origin. The present study aims to answer the existing concerns about electromagnetic exposure in electrotherapy facilities. After monitoring environmental values in an electrotherapy facility, we conclude that actions must be undertaken in order to reduce the exposure levels, as proposed by the current European guidelines, which should become legally binding for all EU state members within the current year. With the purpose of reducing potential risks of occupational overexposure, we are developing innovative fabrics for microwave shielding. These new materials are able to attenuate 85% of the microwave radiation. As these are light materials, they can be used in all kind of facilities, as wall covers, movable screens or even as personal protection, like lab clothes or gloves. (Author) 6 refs.

David Brenner and Eric Hall claim that between 1.5 and 2% of all cancers in the USA may be attributable to exposure to X-ray computerized tomography techniques, given the intensive use of these techniques and the patient dose ranges in which incurred. While this is not debatable, if it is, the alternative does not seem to be abandoning the use of computerized tomography, because it gives them undoubted benefits with respect to invasive procedures. Deserves mention concerns the use of computerized tomography in children using scanning protocols designed for adults, in which case it incurs in 5 times higher dose. An additional warning about unwarranted use of computerized tomography is a procedure of this technique in abdomen resulting in an equivalent dose to 298 times that of a mammogram. Additional aspects such as biological effects (including deterministic) of both medical staff and patients of interventional procedures further reinforces the idea that there are education programs in radiation protection. Attention must put in the new generations, including in the curricula of medical residencies in radiology, endoscopy, cardiology and orthopedic, the education (no emerging courses) in radiation protection, radiobiology, radiology physics, and other topics, but previously must have medical physicists in radiology available to train new

In this report we present the results about radiation controls during 1990 - 2010, carried out in the Nuclear Reactor RP-10 of the Nuclear Center of Huarangal. These controls and radiological evaluation are of much utility for the radio personnel protection of this one and other reactors, since it allows to compares these variables with respect to the time. From the results obtained in monitoring and radiation controls, we conclude that in no case it has been reached the limits allowed by the Peruvian Regulating Authority. (author)

The Pain Clinic of the CIMEQ offers treatment to patients with different pathologies, using interventional techniques as the radiology like visual guide to reach the target structure and to apply the election technique. The personnel that carry out these procedures are inserted in the program of radiological surveillance of the institution, reason for which a radiological event could be detected where the main physician responsible of the service was implied. In this work the results of an investigation are presented realized with the objective of to know the causes of the event and to determine the necessary measures to avoid that this repeats again. The investigation was oriented to three fundamental aspects: medical exam of the affected worker; evaluation of the operational procedures from the radiological protection view point; and dosimetric measurements simulating the real conditions of work for which were used ionization chamber, radiometer and PMMA mannequin. As a result of the medical exam was detected that the main physician of the service did not use during the execution of all the procedures the extremities dosimetry and that he presented a radio induced erythema in the right hand, reason for which he was separated of the activity with ionizing radiations, until the conclusion of the investigation. With relationship to the evaluation of the operational procedures from the radiological protection view point, was verified that the medical physician not carried out any collimation of the beam and he was located in the positions where the dose rate reached the maximum values, frequently introducing the hands in the direct beam; that which implied an overexposure of the superior extremities and a not optimized exposure for whole body. This result was proven with the realized experimental measurements, which gave dose estimated values in extremities of the order of the deterministic effects. The investigation facilitated to introduce modifications in the

According to the IAEA-TECDOC-1312, as it is required by international agreements, the displacement of radioactive material within and among States should be subject to strict regulatory, administrative, safety and technical controls to ensure conditions of technological and physical safety. The Customs Office is one of the institutions responsible for monitoring shipments crossing international borders. Increasing illicit trafficking of radioactive materials, the use of ionizing radiation generating equipment for checking loads, and trade in radioactive substances have informed the need for education in radiation protection of customs officials. Thus, based on a course on radiation protection for Customs officials, organized by the International Atomic Energy Agency, in March 2008 was initiated a course of radiation protection, of 30 hours Carrera Tecnica del Centro de Formacion y Capacitacion Aduanera de Paraguay, which highlights the basic chapters and for transporting, nomenclature, new equipment emitting ionizing radiation and smuggling. Since then, to date, at least 10 groups have completed the training. Within the training program for customs officials, was incorporated a course for radiation protection of operators of baggage scanners with a four-hour program. Finally, since from 2011 and periodically, at various country customs, a workshop on Illicit trafficking of radioactive and nuclear materials is performed. The results of these courses have been very positive, as well as know the proper procedures for dealing with ionizing radiation has increased the safety culture within the institution.

It is widely accepted that damage to DNA is the critical event on irradiated cells, and that double strand breaks are the primary DNA lesions responsible for the biological effects of ionizing radiation. This has lead to the long standing paradigm that these effects, be they cytotoxicity, mutagenesis or malignant transformation, occur in irradiated cells as a consequences of the DNA damage they incur. Evidence has been accumulating over the past decade, however, to indicate that radiation may induce effects that ar not targeted to the irradiated cells itself. Two non-targeted effects will be described in this review. The first, radiation-induced genomic instability, is a phenomenon whereby signals are transmitted to the progeny of the irradiated cell over many generations, leading to the occurrence of genetic effects such as mutations and chromosomal aberrations arising in the distant descendants of the irradiated cell. Second, the bystander effect, is a phenomenon whereby irradiated cells transmit damage signals to non-irradiated cells in a mixed population, leading to genetic effects arising in these bystander cells that received no radiation exposure. the model system described in this review involves dense monolayer cultures exposed to very low fluences of alpha particles. The potential implications of these two phenomena for the analysis of the risk to the human population of exposure to low levels of ionising radiation is discussed. (Author) 111 refs.

The Service of Personal Dosimetry of the External Dosimetry Laboratory of the Centro de Proteccion y Higiene de las Radiaciones - CPHR of Cuba works with an automatic RADOS TLD system and includes the surveillance of the doses of whole body and extremities for photon radiation. The work presents the results of the service in the period 2010-2011, showing data related to the number and distribution of workers monitored for areas. The levels of occupational exposure area analyzed using various indicators such as: annual average dose for areas, number of workers who receive annual doses greater than zero, distribution of workers by dose intervals, and others. These indicators are compared with previous periods and with the values published by the UNSCEAR. In general, the average annual dose for all areas was less than 1 mSv for whole body and 3 mSv for hands. The number of exposed workers experienced significant variation from one year to another, considerably decreasing from 60% to 12% of the total. The work presents an analysis of this behavior and highlights that the country guarantees the personal dosimetry to 100% of exposed workers and that the results of the occupational exposure are within the established requirements.

Every day, the number of didactic materials presented through Internet, is greater. However, we have not effective tools to obtain the potential academic yield of such a media. The complexity of the Internet protocols, in spite of the easy handling, makes it almost impossible. In this work, a didactic tool to analyse graphically the navigation through a tutorial on radiation protection is presented. For its visualisation, some subjects related with the biogical effects of radiation and with radiological quantities and units have been selected. The graphical representation shows the tour travelled by the user, in our case students of Medicine, and the time employed in eyeing each one of the nodes. The answers to problems about the contents of each node and its graphical representation in the navigation map allow us to follow the learning progress of the students as well as their standard of navigation. The graphical representation analysis of multiple users permits to detect some of the mistakes in the design of the tutorial and to suggest to the author a method for amending these mistakes. The system is developed on LINEX, but it is easily adaptable to other operating systems. (Author) 7 refs.

Radiation Protection should be included in the programme of studies necessary to confer a bachelor's degree in Medicine, according to the Directive 97/43 Euratom on medical exposures and the Report RP116 published by the European commission on Education and Training in radiation protection for medical exposures. To analyse the present training programmes in radiation protection at the Medical School in different Spanish Universities. The syllabus and the contents of the subjects including radiation protection issues in 27 Spanish Schools of Medicine have been revised. Radiation protection subjects are obligatory at present, only at the Schools of Medicine from Cantabria and Malaga. There is a group of Schools of Medicine where radiation protection is an optional matter with an extension of 4,5 credits (45 hours). It also exists some topics in radiation protection in subjects dealing with Medical Physics and General Radiology (with a range value from 1 to 10 hours), in 10 Schools of Medicine. A wide dispersion among the contents of different subjects and the hours of training allocated by the different School are found. It should be useful the harmonization of the programmes. (Author)

Primary liver cancer is one of the most frequent in the world and with a low cure rate. Radioembolization using 90y spheres is a promising treatment of this pathology and involves the percutaneous vascular application of radioisotope-labeled the order of Micron size particles. The advantages of this technique include the permit administered high doses of radiation to small volumes with low relative toxicity, offer the possibility of treating all the liver including microscopic tumors, and finally, the feasibility of combined with other therapies. Radiation protection in new medical therapies requires justification and optimization, as requirements for their implementation. The application of the principle of optimization in the context of the protection of the patient must be the minimum that it can be reasonably reached compatible with the required doses of treatment dose to healthy tissue. With {sup 90}Y microspheres therapy this optimization applies to the activity of 90y which is administered to the patient, and estimation methods are postulated. in this work are analyzed comparatively these methods, described the early physicists, equations and the limitations of each. Finally, it is concluded that the optimal method to be implemented for the evaluation of the activity of {sup 90}Y manage must be based in a voxel dosimetric model specific for each patient, however, the partitional method may be a good alternative if you don't have the tools to apply the method.

The Argentine Republic has extensive antecedents in education and training in radiological protection. From the beginning of the nuclear activity in the country was given preponderance to the aspects related with the radiological protection and the personnel's training involved in the employment of ionizing radiations. At the present time these educational activities already overcome the 50 years, there being accumulated a rich and important experience in the matter. In the country the organisms that have assigned by law the responsibility of the regulation and the control of practice them with ionizing radiations are the Nuclear Regulatory Authority and the Ministry of Health and Atmosphere of the Nation. The first one has the mission of protecting people of the noxious effects of the ionizing radiations derived of nuclear activities, the second is in charge of the control of the equipment dedicated specifically to generate X-rays. This includes the responsibility of elaborating, to emit and to make complete the regulations, standards and other corresponding requirements, in particular - in the mark of the present work - regarding to establish demands and to promote education activities and training in radiological protection. The sure use of the benefits that offers the nuclear development in its diverse applications implies to overturn resources, experience and dedication for the personnel's training. In that sense the Argentina has committed recently to undertake the necessary actions to constitute a Regional Center of Education and Training for Latin America and the Caribbean, taking advantage of the important experience obtained in more of 25 years of imparting graduate degree courses in radiological protection and nuclear safety with inter regional and regional character. With that purpose a process of self evaluation has begun (self appraisal), following the limits settled down by the International Atomic Energy Agency in the document &apos

The obtention of images of human body to the medical diagnostic is one of the more old and generalized applications for X-ray. Therefore the design and performance of equipment and installations as well as the operation procedures must be oriented toward safety with the purpose to guarantee this radiological practice will bring a net positive benefit to the society. Given that in Mexico only exists the standardization related to source and equipment generators of ionizing radiation in the industrial area and medical therapy, but not so to the medical diagnostic area it is the purpose of this work to present those standards related with this application branch. Also it is presented the preparation of a manual for the course named Formation of teachers in radiological protection and safety in the X-ray medical diagnostic in 1997 which was imparted at ININ.

A study about the industrial radiography situation in Brazil, concerning to the radiation protection aspects is shown. With this purpose it was made an inventory, with utilization of the file of facilities officially registered in industrial application from Brazilian Nuclear Energy Commission (CNEN). It was evaluated the quantity of accelerators, radiation monitors and radiation workers (health physics, operator). As quality and performance indicators of radiation protection the mean doses and the collective doses were used, and their variation from 1987 to 1990. As deficiency signals of radiological protection programs and procedures were utilized the 175 abnormal event occurred (radiological accident and emergency situation) from 1976 to 1992, after an analysis of their causes. The results showed that, for around 2000 monitored workers, the mean dose equivalent was between 0.83 to 2.70 mSv, and the collective dose, between 1.54 and 6.18 Sv.man, from 1987 to 1990. In this period, it was verified a tendency for reduction of means dose and collective dose values. It indicates a possible improvement of radiation protection services or an influence of economical situation of the country. From 175 abnormal events analysed, 456 persons were exposed, with 7.2% of them receiving doses above 50 mSv. These results were compared with those from others countries, such as United Kingdom and united States. (author). 76 refs, 16 figs, 24 tabs.

The medical irradiations constitute the main contribution to the human exposure to ionizing radiations of artificial character. The growing quantity of practices, facilities and human resources dedicated to such ends, it has increased the concern of regulator organisms and scientific societies by the radiological protection of the patient (PRP). Besides completing it regulatory function in the domains of the medical practices that its concern it, the Nuclear Regulatory Authority (ARN) of Argentina, decided to install an active discussion in order to promoting an action plan in PRP in the national environment. To such end, the ARN organized the First National Day on PRP in December, 2004, with the attendance of professionals of the fields of the Radiodiagnostic, the Nuclear Medicine and the Radiotherapy as well as of representatives of professional associations and authorities of health. In this day the conclusions of the International Conference on PRP (Malaga, 2001) and the approaches of the Directive 97/43/EURATOM adopted in European countries were presented. It was discussed about: practices justification, responsibility of the prescriber doctor, quality systems, dose optimization, reference levels, dosimetry, training of human resources, especially for certain practices (pregnant woman, pediatric radiology and interventionist, PR/118 tomography for the correct application of diagnostic practices and an expert presented in teleconference form the experience of France for the adoption of these guides. During the Second National Day on PRP organized by the ARN (June 2005), received opinions were debated in the different environments in relation to the PR/118 guide and it potential adaptation to the national conditions. Also it was presented the state of advance of the activities developed in relation to the proposed tasks. As a result of this meeting, it was conformed a national net of PRP to which intended to incorporate academic institutions, in order to consider the inclusion of topics of PRP in the medical grade formation. Work groups were constituted in Radiodiagnostic, Radiotherapy, Nuclear Medicine and the PRP of the pregnant woman that agreed the contents and chronograph of a work plan to short and medium term that is at the moment in execution. The continuity of this coordinated action facilitated the execution of the proposed objectives. In this communication the results obtained until the present of the action plan for the PRP implemented in the Argentina starting from the year 2004 are presented. (Author)

In the Secondary Laboratory of Dosimetric Calibration in Mexico was realized the qualities characterization of the series X-rays RQR reported in the International Code of Practices in Dosimetry and Diagnostic Radiology No. 457, using attenuator filters of high purity aluminum and ionizing radiation equipment of inherent filtration of 4 mm Be with and emergent X-radiation beam of 40 grades. For the attenuation was used a geometric arrangement with three beam limiters and a monitor camera prepared on the established form in the mentioned technical report, and a spherical ionization chamber with collection volume of 3.6 cm{sup 3}, aligning its geometric center with the focus of X-rays tube to get that the incident radiation direction will be perpendicular to the ionization chamber. From the perspective of the radiological protection is important to know the X-radiation quality for the application dedicated to the instruments calibration and can to give to these the traceability to a reference laboratory, this way the quality combination and reference chamber can give as a result a procedure for the evaluation of the entrance in surface dose to estimate the dose orientate levels, specified in the basic standards of safety.

The present work has by objective to indicate rules for the establishment and the use of the Radiological Protection Programs (PPR) that are of application to the transport of radioactive materials according to that required by the Transport Regulation of the International Atomic Energy Agency (IAEA). The PPR are established and applied in systematic form for remittent, transport and addressees, to consider the measures of radiological protection and its appropriately control during the transport stages of radioactive material. In particular, in the work it is analyzed the PPR applied to the operative stage, in the one that can be considered as one of the more important documents to use since it summarizes the evaluations and the necessary controls of radiological protection. Also it is analyzed the importance that this document gets ready on the base that it converges in the the analyses, evaluations and data that have been kept in mind during the previous stages of design of bundles and production of packings, the types and quantities of involved bundles, as well as of considering the quantities of expeditions and its frequencies, the ways of transport, etc. It is included a brief description of the parts that the PPR conforms on the base of that suggested in the advanced draft of the TS-G-1.5 Guide 'Radiation Protection Programmes for Transport of Radioactive Material', of October, 2005, of the IAEA: objectives. necessity, scope, basic elements of a PPR in function of the occupational dose. assignment of functions and responsibilities for the establishment of a PPR, evaluation and dose optimization, surface contamination, segregation and other protection measures, responses in emergencies. training and administration systems for baled and transport of radioactive material. Next an example of PPR for the transport of bundles of the A Type by lorry with content of radiopharmaceuticals that are the bundles more used worldwide in the expeditions of radioactive materials and the way of transport more frequently used is developed. Finally, some conclusions about the necessity that at short term the IAEA publishes the TS-G-1.5 Guide not only in English but also in the official languages of the Organism, and that senders, transport companies and addressees settle down, apply or improve their PPR in harmonization with that suggested in the mentioned guide.

Triple-aspect monism: physiological, mental unconscious and conscious aspects of brain activity.

Science.gov (United States)

Pereira, Alfredo

2014-06-01

Brain activity contains three fundamental aspects: (a) The physiological aspect, covering all kinds of processes that involve matter and/or energy; (b) the mental unconscious aspect, consisting of dynamical patterns (i.e., frequency, amplitude and phase-modulated waves) embodied in neural activity. These patterns are variously operated (transmitted, stored, combined, matched, amplified, erased, etc), forming cognitive and emotional unconscious processes and (c) the mental conscious aspect, consisting of feelings experienced in the first-person perspective and cognitive functions grounded in feelings, as memory formation, selection of the focus of attention, voluntary behavior, aesthetical appraisal and ethical judgment. Triple-aspect monism (TAM) is a philosophical theory that provides a model of the relation of the three aspects. Spatially distributed neuronal dendritic potentials generate amplitude-modulated waveforms transmitted to the extracellular medium and adjacent astrocytes, prompting the formation of large waves in the astrocyte network, which are claimed to both integrate distributed information and instantiate feelings. According to the valence of the feeling, the large wave feeds back on neuronal synapses, modulating (reinforcing or depressing) cognitive and behavioral functions.

In this work a historical revision of the exposure magnitude development and their roentgen unit (1905 - 2011) is made, noting that it had their origin in the electric methods for the detection of the ionizing radiation in the period of 1895 at 1937. However, the ionization is not who better characterizes the physical, chemical and biological effects of the ionizing radiations, but is the energy deposited by this radiation in the interest bodies, which led historically to the development of dosimetric magnitudes in energy terms like they are: the absorbed dose D (1950), the kerma K (1958) and the equivalent dose H (1962). These dosimetric magnitudes culminated with the definition of the effective equivalent dose or effective dose which is not measurable and should be considered with the operative magnitudes ICRU: H environmental equivalent dose and/or H directional equivalent dose, which can be determined by means of a conversion coefficient that is applied to the exposure, kerma in air, fluence, etc. (Author)

The aspect system of the Chandra Observatory plays a key role in realizing the full potential of Chandra's x-ray optics and detectors. To achieve the highest spatial and spectral resolution (for grating observations), an accurate post-facto time history of the spacecraft attitude and internal alignment is needed. The CXC has developed a suite of tools which process sensor data from the aspect camera assembly and gyroscopes, and produce the spacecraft aspect solution. In this poster, the design of the aspect pipeline software is briefly described, followed by details of aspect system performance during the first eight months of flight. The two key metrics of aspect performance are: image reconstruction accuracy, which measures the x-ray image blurring introduced by aspect; and celestial location, which is the accuracy of detected source positions in absolute sky coordinates.

The Large Aspect Ratio Tokamak Study (LARTS) at Oak Ridge National Laboratory (ORNL) investigated the potential for producing a viable longburn tokamak reactor by enhancing the volt-second capability of the ohmic heating transformer through the use of high aspect ratio designs. The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were assessed in the context of extended burn operation. Using a one-dimensional transport code plasma startup and burn parameters were addressed. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the startup and shutdown portions of the tokamak cycle. A representative large aspect ratio tokamak with an aspect ratio of 8 was found to achieve a burn time of 3.5 h at capital cost only approx. 25% greater than that of a moderate aspect ratio design tokamak

In the patients with differentiated thyroid cancer (CADIT) subjected to therapy with radiopharmaceuticals should be considered the possible risk of sharp depression of the bone marrow like consequence of the intolerance to the quantity of administered activity. The manifestation of the myelotoxicity can limit in a substantial way the future treatments and to deteriorate the predict of resolution of the illness. In this work it shows the physical-mathematical mark of a methodology for the estimated absorbed dose in bone marrow based in the MIRD scheme whose objective is to protect the one patient of the noxious and undesirable effects of the internal radiotherapy in organs that are not target of the same one. The formalism incorporates specific information of the patient and also peculiar characteristics of the internal therapy in patient with CADIT. The considerations are the following ones: (1) the main organ to protect is the bone marrow: (2) the accumulated activity, in bone marrow, it is obtained starting from measurements in blood: (3) the used isotope almost exclusively in this type of therapies is the {sup 131}I; (4) it is used as radiopharmaceutical at the {sup 131}INa that it is characterized to be a simple, inorganic and small molecule: (5) the statistical incidence of the CADIT is bigger in women than in men. It is explained for that it was selected the formalism that is presented, the principles on which it is sustained which are their reaches and their limitations. They are also presented future innovations that can be implemented to effects of improving the estimates. The work is framed inside the thematic of the medical applications of open radioactive sources and it constitutes a contribution to the invigoration of the internal therapy with radiopharmaceuticals. This is due to that the methodology of dose estimation presented supplements with a theoretical biophysics base the protocols of empiric prescription broadly used in this practice. For these reasons, the dosimetric information obtained, adjusted to each concrete case, it contributes to improve the radiological protection of the patient. (Author)

The Large Aspect Ratio Tokamak Study (LARTS) investigated the potential for producing a viable long burn tokamak reactor through enhanced volt-second capability of the ohmic heating transformer by employing high aspect ratio designs. The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were accessed in the context of extended burn operation. Plasma startup and burn parameters were addressed using a one-dimensional transport code. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the field in the ohmic heating coil and the wave shape of the ohmic heating discharge. A high aspect ratio reference reactor was chosen and configured

Cognitive aspects of color

Derefeldt, Gunilla A. M.; Menu, Jean-Pierre; Swartling, Tiina

1995-04-01

This report surveys cognitive aspects of color in terms of behavioral, neuropsychological, and neurophysiological data. Color is usually defined as psychophysical color or as perceived color. Behavioral data on categorical color perception, absolute judgement of colors, color coding, visual search, and visual awareness refer to the more cognitive aspects of color. These are of major importance in visual synthesis and spatial organization, as already shown by the Gestalt psychologists. Neuropsychological and neurophysiological findings provide evidence for an interrelation between cognitive color and spatial organization. Color also enhances planning strategies, as has been shown by studies on color and eye movements. Memory colors and the color- language connections in the brain also belong among the cognitive aspects of color.

Health care should ensure the safety of a number of people, equipment and clinical practices to achieve quality service offering. Work systems should minimize the risks of health care and the environment for patients, families and professionals, avoiding as much as possible, errors that may be committed. A rigorous and methodologically sound study of the circumstances in which errors occur will help to establish secure systems that can prevent errors regardless of the human factor, detecting latent conditions that are the root causes of the errors on the need influence.

The possible occurrence of accidents involving sources of ionizing radiation demands response plans to mitigate the consequences of radiological accidents. This paper offers orientations in order to elaborate emergency planning for institutions with medical applications of ionizing radiation. Taking into account that the prevention of accidents is of prime importance in dealing with radioactive materials and others sources of ionizing radiation, such as X-rays, it is recommended that one include in emergency instructions and procedures several aspects relative to causes which originate these radiological events. Topics such as identification of radiological events in these practices and their consequences, protective measures, planning for and emergency response and maintenance of emergency capacity, are considered in this article.

The use of the nuclear techniques in the social practice confers a special imporatnce to the relative aspects to the safety of the practices and radiationsources, for what the implementation of efficient programs of radiation protection constitutes a priority. However in spite of the will before expressed, regrettably radiological situations happen accidental assocaited to multiple causes taht suggest the creation of response capacities to intervention before these fortuitous facts. The experiences accumulated in the last decades related with accidental exposures have evidenced the convenience of having properly qualified human resources for the Medical Response in Radiological Emergencies. The training in the medical aspects of the radiological emergencies acquires a singular character. In such a sense when valuing the national situation put onof manifest deficiences as for the training in medical aspects of the radiological emergencies that advised the development of training programs in such aspects for the different response groups linked to the topic. After identified the training necessities and the scope of the same ones, the contents of the training program were elaborated. The program has as general purpose the invigoration of the capacity of the medical response in front of accidental radiological situations, by means of actions that they bear to prepare groups of medical response in the handling of people accident victims and to the identification of potentials,accidental scenarios, as well as of the necessary resources to confront them. The program content approaches theoretical and paractical aspects to the medical aspect to radiological emergencies. The program include the different topics about fundamental of physical biological to radiation protection, radiation protection during exposure of radiological accidents, medical care for overexposed or contaminated persons, drill, exercises and concludes with designation of a strategy as preparation and

2011-01-01

Background and Aims Functional–structural plant models (FSPMs) are used to integrate knowledge and test hypotheses of plant behaviour, and to aid in the development of decision support systems. A significant amount of effort is being put into providing a sound methodology for building them. Standard techniques, such as procedural or object-oriented programming, are not suited for clearly separating aspects of plant function that criss-cross between different components of plant structure, which makes it difficult to reuse and share their implementations. The aim of this paper is to present an aspect-oriented programming approach that helps to overcome this difficulty. Methods The L-system-based plant modelling language L+C was used to develop an aspect-oriented approach to plant modelling based on multi-modules. Each element of the plant structure was represented by a sequence of L-system modules (rather than a single module), with each module representing an aspect of the element's function. Separate sets of productions were used for modelling each aspect, with context-sensitive rules facilitated by local lists of modules to consider/ignore. Aspect weaving or communication between aspects was made possible through the use of pseudo-L-systems, where the strict-predecessor of a production rule was specified as a multi-module. Key Results The new approach was used to integrate previously modelled aspects of carbon dynamics, apical dominance and biomechanics with a model of a developing kiwifruit shoot. These aspects were specified independently and their implementation was based on source code provided by the original authors without major changes. Conclusions This new aspect-oriented approach to plant modelling is well suited for studying complex phenomena in plant science, because it can be used to integrate separate models of individual aspects of plant development and function, both previously constructed and new, into clearly organized, comprehensive FSPMs. In

Verb aspect, alternations and quantification

Directory of Open Access Journals (Sweden)

Svetla Koeva

2015-11-01

Full Text Available Verb aspect, alternations and quantification In this paper we are briefly discuss the nature of Bulgarian verb aspect and argue that the verb aspect pairs are different lexical units with different (although related meaning, different argument structure (reflecting categories, explicitness and referential status of arguments and different sets of semantic and syntactic alternations. The verb prefixes resulting in perfective verbs derivation in some cases can be interpreted as lexical quantifiers as well. Thus the Bulgarian verb aspect is related (in different way both with the potential for the generation of alternations and with the prefixal lexical quantification. It is shown that the scope of the lexical quantification by means of verbal prefixes is the quantified verb phrase and the scope remains constant in all derived alternations. The paper concerns the basic issues of these complex problems, while the detailed description of the conditions satisfying particular alternation or particular lexical quantification are subject of a more detailed study.

Verbal aspect category and some ways of distinguishing of aspect pairs of verbs

Directory of Open Access Journals (Sweden)

Elena V. Sheyko

2016-09-01

Full Text Available The article discusses one of the most complex grammatical categories of the verb - category of the aspect, it is noted that there are still unsolved issues relating to the status of this category, its volume, ratio to the aspect pairs of verbs. One group of scientists after V.V. Vinogradov calls category of aspect as word-changing on the basis of the lexical identity of aspect pairs, another group, and in particular I.G. Miloslavsky, relates it to the formative, the third group, which representative is L.A. Mesenyashina, tryes to find a compromise, and those verbs, which syntactic-functional series are identical, calls paired, and those verbs in which there are significant differences in compatibility, calls different lexems. Thus it is accounted only the compatibility of verbs with the word forms, as well as many verbs can act as a reference in subordinate clauses, and in this case their compatibility in different lexical-semantic versions may vary. It is shown on the example of the verbs “чувствовать – почувствовать», which in the majority of lexicographical sources are named paired verbs, but their compatibility is not the same, and therefore, they can not be called as aspect pair. Therefore, in determining the pair/unpair verbs we should proceed from the same or not the same invariant meaning of verbs (in the terminology of A. Timberlake, take into account their multiple meanings and compatibility in different LSV and consider compatibility not only at the level of word forms, but also at the level of a complex sentence.

The risks of the radiation in computed tomography (CT) studies have been recently reported in many works. Caution should be had in the environment of the exploration in the patient. To maintain the radiation doses so low as is reasonably possible during the CT examination, is important that in the CT the parameters are correctly adjusted for each patient with the purpose of having the minimum dose in the application of the study. Thermoluminescent dosimeters were used to measure the absorbed dose and to measure the CT profiles of dose. The distribution of the dose in the CT abdominal examination in the simulated patients was evaluated. The exploration parameters of the CT were 130 kV, 90 m A, with a cut thickness of 3 mm and a field of 1.0 in the pitch. The assignment dose was increased in an axis along the direction of the study, they were also studied. The equivalent dose due to the direct and dispersed radiation was determined during the procedures of the irradiation in pelvis examinations, for the next areas to the study like is in specific the critical organ (gonads) that is the terminal area of the exploration. During this study of 26 cuts was obtained an equivalent dose to critical organ of 14.27 mSv. (Author)

The purpose of this work, in general form, is to describe a practical method for reduction of hot particles generated as consequence of the operational activities of BWR nuclear reactors. This methodology provides a description of the localizations and/or probable activities of finding particles highly radioactive denominated hot particles. For this purpose it was developed a strategy based on the decontamination lineaments, as well as the manipulation, gathering, registration, contention, documentation, control and final disposition of the hot particles. In addition, some recommendations are reiterated and alternative, in order to gathering the hot particles in a dynamic way given to the activities of the personal occupationally exposed in highly radioactive areas. The structure of the methodology of hot particles is supported in the radiological controls based on the Code of Federal Regulation 10 CFR 20 as well as the applicable regulatory documents. It provides an idea based on administrative controls of radiological protection, in order to suggesting the responsibilities and necessary directing for the control of the hot particles required in nuclear plants of the BWR type.

Between 1969 and 1971 the National Commission of Nuclear Energy and the Mining Fostering Commission operated coordinately a production plant of uranium and molybdenum concentrates (Benefit plant) at Ciudad Aldama, Chihuahua, Mexico. During two years of operation some 45 tonnes of uranium concentrate and approximately 35,000 tonnes of uranium wetlands were produced. These last were stored in a dam to 120 m. toward West of the plant. Due to the nearness of the population with respect to what was the Benefit plant and over all to the wetland dam, the objective of this work had two main aspects: On the one hand, to carry out the works of radiological decontamination of the benefit plant of uranium, according to the established normative by the Regulatory organization in matter of radiological safety and protection (CNSNS) for the population and the hard workers. After that the works mentioned were realized it was considered that the estate which comprises what was the Benefit plant did not reach the established criteria by the CNSNS for being considered of unrestricted use such estate and it was not allowed any type of construction in the zone which could be showed the residual contamination which remains there. On the other hand, to determine the site where could be stored the radioactive wastes generated by the radiological decontamination and the wetland mobilization for its definitive storage in benefit of the present population and of the future generations due to the radionuclides which are in a such material. The site more adequate technical and economically to storage the wastes generated by this activity was evaluated. Whereby studies about demography, use of soil and water, meteorology, hydrology and ecology were realized. The site selected being in the Pena Blanca mountains, Chihuahua, place where is located one of the uranium zones and the most important of the country. In this work, specific objectives also were treated such as: knowing the radiological

The purpose of this report is to document the environmental aspects and associated environmental impacts of the Bechtel SAIC Company (BSC) scope of work, evaluate the significance of those environmental aspects based on established criteria, and establish environmental objectives and targets for specific environmental aspects. This report is intended to be used by environmental staff in the evaluation of BSC work packages during the annual risk-based planning process. This report shall be fully reviewed and revised annually during the annual work planning process to reflect changes in BSC operations, facilities, and scope of work. Planned BSC work will be evaluated to determine if the work is covered by a previously defined activity, product or service (see Table 2); if work activities require redefinition or addition of a new activity; and if the significant evaluation for each environment aspect is still valid based on scope of planned work. New workscope initiated during the fiscal year through the Baseline Change Proposal process (i.e., not as part of the annual work plan) also will be reviewed for new environmental aspects and determination of whether the new workscope would change the significance rating of any environmental aspect. If a new environmental aspect is identified in a new work activity, product, or service but the aspect is not determined to be significant (see Section 4), then this report can be changed through an interim change notice (ICN). This report can be changed five times through an ICN before a full revision is required. However, if new workscope causes an environmental aspect to be graded as significant using the evaluation process in Section 4, this report shall be revised though a full review and revision

Full Text Available Unified Modeling Language is the most popular and widely used Object-Oriented modelling language in the IT industry. This study focuses on investigating the ability to expand UML to some extent to model crosscutting concerns (Aspects to support AspectJ. Through a comprehensive literature review, we identify and extensively examine all the available Aspect-Oriented UML modelling approaches and find that the existing Aspect-Oriented Design Modelling approaches using UML cannot be considered to provide a framework for a comprehensive Aspectual UML modelling approach and also that there is a lack of adequate Aspect-Oriented tool support. This study also proposes a set of Aspectual UML semantic rules and attempts to generate AspectJ pseudocode from UML diagrams. The proposed Aspectual UML modelling approach is formally evaluated using a focus group to test six hypotheses regarding performance; a “good design” criteria-based evaluation to assess the quality of the design; and an AspectJ-based evaluation as a reference measurement-based evaluation. The results of the focus group evaluation confirm all the hypotheses put forward regarding the proposed approach. The proposed approach provides a comprehensive set of Aspectual UML structural and behavioral diagrams, which are designed and implemented based on a comprehensive and detailed set of AspectJ programming constructs.

Safeguarding, supporting and protecting adults and children in vulnerable situations; leading, co-ordinating and managing care; functioning as an effective and confident member of the multidisciplinary team; and managing risk while maintaining a safe environment for patients and colleagues, are vital aspects of this cluster. This article discusses the roles and responsibilities of the newly registered graduate nurse. Throughout their education, nursing students work towards attaining this knowledge and these skills in preparation for their future roles as nurses.

Ranking product aspects through sentiment analysis of online reviews

Science.gov (United States)

Wang, Wei; Wang, Hongwei; Song, Yuan

2017-03-01

The electronic word-of-mouth (e-WOM) is one of the most important among all the factors affecting consumers' behaviours. Opinions towards a product through online reviews will influence purchase decisions of other online consumers by changing their perceptions on the product quality. Furthermore, each product aspect may impact consumers' intentions differently. Thus, sentiment analysis and econometric models are incorporated to examine the relationship between purchase intentions and aspect-opinion pairs, which enable the weight estimation for each product aspect. We first identify product aspects and reduce dimensions to extract aspect-opinion pairs. Next the information gain is calculated for each aspect through entropy theory. Based on sentiment polarity and sentiment strength, we formulate an econometric model by integrating the information gain to measure the aspect's weight. In the experiment, we track 386 digital cameras on Amazon for 39 months, and results show that the aspect weight for digital cameras is detected more precisely than TF-ID and HAC algorithms. The results will bridge product aspects and consumption intention to facilitate e-WOM-based marketing.

Ethical aspects of nuclear power

International Nuclear Information System (INIS)

1989-01-01

The nuclear controversy comprises many ethical aspects, e.g. the waste disposal problem. Nuclear opponents should not neglect the environmental protection aspect; for example, the use of nuclear power alone brought about an 8% reduction of the CO 2 burden in 1987. Our responsibility towards nature and humans in the Third World leaves us no alternative to nuclear power. On the other hand, the nuclear power debate should not become a matter of religious beliefs.

Modeling Submarine Lava Flow with ASPECT

Science.gov (United States)

Storvick, E. R.; Lu, H.; Choi, E.

2017-12-01

Submarine lava flow is not easily observed and experimented on due to limited accessibility and challenges posed by the fast solidification of lava and the associated drastic changes in rheology. However, recent advances in numerical modeling techniques might address some of these challenges and provide unprecedented insight into the mechanics of submarine lava flow and conditions determining its wide-ranging morphologies. In this study, we explore the applicability ASPECT, Advanced Solver for Problems in Earth's ConvecTion, to submarine lava flow. ASPECT is a parallel finite element code that solves problems of thermal convection in the Earth's mantle. We will assess ASPECT's capability to model submarine lava flow by observing models of lava flow morphology simulated with GALE, a long-term tectonics finite element analysis code, with models created using comparable settings and parameters in ASPECT. From these observations we will contrast the differing models in order to identify the benefits of each code. While doing so, we anticipate we will learn about the conditions required for end-members of lava flow morphology, for example, pillows and sheet flows. With ASPECT specifically we focus on 1) whether the lava rheology can be implemented; 2) how effective the AMR is in resolving morphologies of the solidified crust; 3) whether and under what conditions the end-members of the lava flow morphologies, pillows and sheets, can be reproduced.

Aspect Βased Classification Model for Social Reviews

Directory of Open Access Journals (Sweden)

J. Mir

2017-12-01

Full Text Available Aspect based opinion mining investigates deeply, the emotions related to one’s aspects. Aspects and opinion word identification is the core task of aspect based opinion mining. In previous studies aspect based opinion mining have been applied on service or product domain. Moreover, product reviews are short and simple whereas, social reviews are long and complex. However, this study introduces an efficient model for social reviews which classifies aspects and opinion words related to social domain. The main contributions of this paper are auto tagging and data training phase, feature set definition and dictionary usage. Proposed model results are compared with CR model and Naïve Bayes classifier on same dataset having accuracy 98.17% and precision 96.01%, while recall and F1 are 96.00% and 96.01% respectively. The experimental results show that the proposed model performs better than the CR model and Naïve Bayes classifier.

Inside the mark of the regulatory control it takes a preponderant place the control of sealed and open radioactive sources, in oil applications. In this task, the handling of the radioactive sources, the demand of the use of written procedures and the training, they are only some examples, of all those that conform the regulatory control. Among these topics they stand out a series of aspects divided in three big groups: operative radiological safety in the base, in the transport and in the task properly said. Given the great quantity of aspects that should be kept in mind, as well as the integration of all the control processes should be included strongly, aspects of safety and quality culture, and to introduce improvements as for the prevention refers, to correct deviations and remoteness that can be produced, avoiding like this, situations of radiological risk, emphasizing aspects of perception of the risk, training in attitudes, the implementation of audits and verifications of the safety level of the installation and the pursuit and control of the tasks that involve the manipulation of radioactive material, which are described in this work.

The discovery of X-ray was a great achievement for humanity, especially for the medical community. In Intensive Care Units (ICUs), the RX tests, performed with mobile devices, add immense value to the diagnosis of inpatients who do not have the option to carry them out of bed. Following the technology and its improvements, fatalities arose from misuse of ionizing radiation, which mostly gave up for lack of knowledge of the biological effects caused by them, which leads to fear among professionals and often prevents a quick job and effectively by professionals of radiological techniques. The research it is a systematic review of the literature and justified by the scarcity of materials that reflect on the radiological protection in ICUs. For this study we found the Virtual Health Library (VHL) and Pubmed were indexed terms radiological protection and intensive care units, the search in Portuguese and English terms were used radiological protection and intensive care unit. The study aims to inform professionals of ICUs on the main aspects that refer to X-rays in hospital beds, the standards of radiological protection and personal protective equipment, thus avoiding possible damage to the biological health of workers, addressing subjects in rules and laws about the X radiation, emphasizing the protection of professionals in intensive care. It is clear, finally, that little research is conducted in the context of radiological protection of workers ICU's and this is a place that receives daily RX equipment, deserving more attention to protect the worker.

Some global aspects regarding nuclear spent fuel management

International Nuclear Information System (INIS)

Ohai, Dumitru; Postoaca, Marius Marcel

2002-01-01

The globalization means the worldwide extension of certain aspects of social or economic processes, structural or environmental changes, or concerning working methodologies, technical activity, industrial production, etc. At present the emergence of global aspects is more frequently observed, being determined by the rapid development of computerized systems and of transfer of information, by the development of big transnational companies and due to the increasing international co-operation. Some of the manifested global aspects could be beneficial for the development of the human society, other could be not. It is necessary to perform an adequate analysis from this view point and to promote appropriate measures to enhance the positive global aspects and to mitigate the negative global aspects. These measures can have a good efficiency only if they are pursued at global level, but for this it is necessary to build an adequate international coordinating body, having the corresponding instruments for action. The global aspects identified in the field of nuclear power may be divided into two categories, namely: - related to the main features of nuclear power; - regarding the specific features of some subdivisions of the field, as for example, spent fuel management. In the paper both categories are discussed. The influence of the global aspects on the development of nuclear power and particularly on the back end activities of the fuel cycle, is also presented. At the same time, some possible actions for enhancing nuclear power development are proposed

The value of a systematic radiologic analysis in constitutional osteochondrodysplasias remains underestimated by both neonatologists and radiologists. The authors report the clinical experience of the Department of Neonatology and Neonatal Intensive Cure Unit of St. John Hospital in Rome with constitutional osteochondrodysplasias identifiable at birth. The authors justify the relatively high incidence of constitutional osteochondrodysplasias in this study (66% versus an average incidence of 0,076% reported in the world population) on the basis of: a) an increasing number of high-risk newborns in the intensive cure; b) an improvement in our clinical and radiologic diagnostic skill.

Güney, Burcu Gülay; Şeker, Hayati

2017-11-01

Scientific literacy is one of the primary purposes of science education which briefly focuses on using and interpreting scientific explanations, understanding science within its culture. However, science curricula emphasize science with its cognitive aspects and underestimate affective and aesthetic aspects of science. Science education needs to cover beauty of science for students to cross borders between their own culture and culture of science and to achieve the aim of scientific literacy. Relating aesthetic aspects of science with content of science and paving the way for aesthetic experiences through artworks may enrich science education. The purposes of this study are to discuss the need of integrating aesthetic aspects of science in science instruction and to propose examples and pedagogical suggestions to promote aesthetic experiences into the science education. Artworks are selected to present socio-cultural aspects of science to demonstrate the culture of science, their stories are explained, and pedagogical suggestions are proposed. Advantages and difficulties of using artworks in science instruction are discussed as a result of the study.

Behavioural aspects of terrorism.

2013-05-10

Behavioural and social sciences are useful in collecting and analysing intelligence data, understanding terrorism, and developing strategies to combat terrorism. This article aims to examine the psychopathological concepts of terrorism and discusses the developing roles for behavioural scientists. A systematic review was conducted of studies investigating behavioural aspects of terrorism. These studies were identified by a systematic search of databases, textbooks, and a supplementary manual search of references. Several fundamental concepts were identified that continue to influence the motives and the majority of the behaviours of those who support or engage in this kind of specific violence. Regardless of the psychological aspects and new roles for psychiatrists, the behavioural sciences will continue to be called upon to assist in developing better methods to gather and analyse intelligence, to understand terrorism, and perhaps to stem the radicalisation process.

Following the Social Media: Aspect Evolution of Online Discussion

Science.gov (United States)

Tang, Xuning; Yang, Christopher C.

Due to the advance of Internet and Web 2.0 technologies, it is easy to extract thousands of threads about a topic of interest from an online forum but it is nontrivial to capture the blueprint of different aspects (i.e., subtopic, or facet) associated with the topic. To better understand and analyze a forum discussion given topic, it is important to uncover the evolution relationships (temporal dependencies) between different topic aspects (i.e. how the discussion topic is evolving). Traditional Topic Detection and Tracking (TDT) techniques usually organize topics as a flat structure but it does not present the evolution relationships between topic aspects. In addition, the properties of short and sparse messages make the content-based TDT techniques difficult to perform well in identifying evolution relationships. The contributions in this paper are two-folded. We formally define a topic aspect evolution graph modeling framework and propose to utilize social network information, content similarity and temporal proximity to model evolution relationships between topic aspects. The experimental results showed that, by incorporating social network information, our technique significantly outperformed content-based technique in the task of extracting evolution relationships between topic aspects.

Optimizing Aspect-Oriented Mechanisms for Embedded Applications

Science.gov (United States)

Hundt, Christine; Stöhr, Daniel; Glesner, Sabine

As applications for small embedded mobile devices are getting larger and more complex, it becomes inevitable to adopt more advanced software engineering methods from the field of desktop application development. Aspect-oriented programming (AOP) is a promising approach due to its advanced modularization capabilities. However, existing AOP languages tend to add a substantial overhead in both execution time and code size which restricts their practicality for small devices with limited resources. In this paper, we present optimizations for aspect-oriented mechanisms at the level of the virtual machine. Our experiments show that these optimizations yield a considerable performance gain along with a reduction of the code size. Thus, our optimizations establish the base for using advanced aspect-oriented modularization techniques for developing Java applications on small embedded devices.

Selected aspects of fusion reactions

International Nuclear Information System (INIS)

Lacroix, D.

2003-01-01

In this lecture, we present selected aspects of nuclear fusion. The importance of the initial geometry of the reaction and its relation to fusion barrier are first discussed. The effect of deformation leading to the notion of barrier distribution is then illustrated. After a brief overview of the advantages of macroscopic theories, the dynamics of nuclear system under large amplitude motion is reviewed. The di-nuclear concept is presented to understand the competition between fusion and quasi-fission. This concept is then generalized to account for the dissipative dynamics in multidimensional collective space. The last part of this lecture is devoted to new aspects encountered with radioactive beams specific properties of very extended neutron rich system, influence of pygmy or soft dipole resonances and charge exchange far from stability are discussed.

Transport in a small aspect ratio torus

International Nuclear Information System (INIS)

White, R.B.; Gates, D.A.; Mynick, H.E.

2005-01-01

Transport theory in toroidal devices often assumes large aspect ratio and also assumes the poloidal field is small compared to the toroidal field. These assumptions result in transport which in the low collision rate limit is dominated by banana orbits, giving the largest collisionless excursion of a particle from an initial flux surface. However in a small aspect ratio device the gyro radius may be larger than the banana excursion, resulting in significant deviations from the standard neoclassical predictions. In this paper we report numerical simulation of diffusion in low and high beta low aspect ratio equilibria. We also sketch an analytic theory. The diffusion, which we refer to as omniclassical, is a combination of neoclassical and properly averaged classical effects, and can be two or three times the neoclassical value. Good agreement of the analytic theory with numerical simulations is obtained. (author)

Integer Linear Programming for Constrained Multi-Aspect Committee Review Assignment

Science.gov (United States)

Karimzadehgan, Maryam; Zhai, ChengXiang

2011-01-01

Automatic review assignment can significantly improve the productivity of many people such as conference organizers, journal editors and grant administrators. A general setup of the review assignment problem involves assigning a set of reviewers on a committee to a set of documents to be reviewed under the constraint of review quota so that the reviewers assigned to a document can collectively cover multiple topic aspects of the document. No previous work has addressed such a setup of committee review assignments while also considering matching multiple aspects of topics and expertise. In this paper, we tackle the problem of committee review assignment with multi-aspect expertise matching by casting it as an integer linear programming problem. The proposed algorithm can naturally accommodate any probabilistic or deterministic method for modeling multiple aspects to automate committee review assignments. Evaluation using a multi-aspect review assignment test set constructed using ACM SIGIR publications shows that the proposed algorithm is effective and efficient for committee review assignments based on multi-aspect expertise matching.

Huei Peng; Wang, K.

1992-01-01

We propose that the geometric and standard gauge field aspects of gravity are equally essential for a complete description of gravity and can be reconciled. We show that this dualism of gravity resolves the dimensional Newtonian constant problem in both quantum gravity and unification schemes involving gravity (i.e., the Newtonian constant is no longer the coupling constant in the gauge aspect of gravity) and reveals the profound similarity between gravity and other fields. 23 refs., 3 tabs

Tense and aspect in Lamnsoʹ

Directory of Open Access Journals (Sweden)

Lendzemo Constantine Yuka

2012-12-01

Full Text Available Yuka (1997 has identified three broad tenses in Lamnso’2. A closer look at these tenses and their specification of time reference willreveal a more complex tense structure of multiple past and future timeallusions that distinguish different degrees of remoteness to the pastand future tense categories. This paper seeks to determine the variousdegrees of remoteness to a given tense category exhibited in Lamnso’. This paper investigates the relative relationship(s between a tense marker that denotes the time of an action and the time reference preceding or following that action within the clause. It also examines aspect, interpreted as the way of conceiving the flow of an event (Comrie, 1976. This study identifies seven tense forms for Lamnso’ (P3, P2, P1, P0, F1, F2 and F3., which specify time distinctions from the remote past (P3 to the remote future (F3 and three aspect forms. These ten tense and aspect forms combine with distinctive tones and time adverbials to derive a time reference structure whose cut-off points are sometimes fluid and non-rigid.

2008-01-01

This is a summary of talks about quantum aspects of cosmology. Topics involve the properties of quantum matter fields on an expanding spacetime as well as issues in the quantization of gravity itself. This session had three parts, one of which was in a joint session with quantum aspects of black holes (D1) and other quantum aspects (D3). The first block of talks was related to quantum aspects of field theories on a classical spacetime (with possible back-reaction), while the second block dealt in several ways with quantizations of gravity itself. The two talks in the combined session discussed issues in quantum theory on de Sitter space and will therefore be included here in the summary of the first block.

Microeconomic aspects of energy crops cultivation

International Nuclear Information System (INIS)

Bartolelli, V.; Mutinati, G.; Pisani, F.

The topic of energy crops, namely of those crops designed to produce biomass to transform into ethanol, has been explored, in Italy and abroad, in all its technical and agronomical aspects. The microeconomic aspect, including the evaluation of convenience for the farmer in adopting such crops, is, on the contrary, less well researched. RENAGRI has developed a research methodology able to give information about the level of convenience of two energy crops (Sweet Sorghum and Topinambour) and has applied it to different Italian agricultural situations, in order to verify the existence of conditions favourable to the cultivation of the two crops, or to indicate the necessity of eventual subvention.

Achieving high aspect ratio wrinkles by modifying material network stress.

Science.gov (United States)

Chen, Yu-Cheng; Wang, Yan; McCarthy, Thomas J; Crosby, Alfred J

2017-06-07

Wrinkle aspect ratio, or the amplitude divided by the wavelength, is hindered by strain localization transitions when an increasing global compressive stress is applied to synthetic material systems. However, many examples from living organisms show extremely high aspect ratios, such as gut villi and flower petals. We use three experimental approaches to demonstrate that these high aspect ratio structures can be achieved by modifying the network stress in the wrinkle substrate. We modify the wrinkle stress and effectively delay the strain localization transition, such as folding, to larger aspect ratios by using a zero-stress initial wavy substrate, creating a secondary network with post-curing, or using chemical stress relaxation materials. A wrinkle aspect ratio as high as 0.85, almost three times higher than common values of synthetic wrinkles, is achieved, and a quantitative framework is presented to provide understanding the different strategies and predictions for future investigations.

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

Sentiment Analysis on Tweets about Diabetes: An Aspect-Level Approach

KAUST Repository

Salas-Zárate, María del Pilar

2017-02-19

In recent years, some methods of sentiment analysis have been developed for the health domain; however, the diabetes domain has not been explored yet. In addition, there is a lack of approaches that analyze the positive or negative orientation of each aspect contained in a document (a review, a piece of news, and a tweet, among others). Based on this understanding, we propose an aspect-level sentiment analysis method based on ontologies in the diabetes domain. The sentiment of the aspects is calculated by considering the words around the aspect which are obtained through N-gram methods (N-gram after, N-gram before, and N-gram around). To evaluate the effectiveness of our method, we obtained a corpus from Twitter, which has been manually labelled at aspect level as positive, negative, or neutral. The experimental results show that the best result was obtained through the N-gram around method with a precision of 81.93%, a recall of 81.13%, and an -measure of 81.24%.

In recent years, some methods of sentiment analysis have been developed for the health domain; however, the diabetes domain has not been explored yet. In addition, there is a lack of approaches that analyze the positive or negative orientation of each aspect contained in a document (a review, a piece of news, and a tweet, among others). Based on this understanding, we propose an aspect-level sentiment analysis method based on ontologies in the diabetes domain. The sentiment of the aspects is calculated by considering the words around the aspect which are obtained through N-gram methods (N-gram after, N-gram before, and N-gram around). To evaluate the effectiveness of our method, we obtained a corpus from Twitter, which has been manually labelled at aspect level as positive, negative, or neutral. The experimental results show that the best result was obtained through the N-gram around method with a precision of 81.93%, a recall of 81.13%, and an -measure of 81.24%.

AMFIBIA: A Meta-Model for the Integration of Business Process Modelling Aspects

DEFF Research Database (Denmark)

Axenath, Björn; Kindler, Ekkart; Rubin, Vladimir

2007-01-01

AMFIBIA is a meta-model that formalises the essential aspects and concepts of business processes. Though AMFIBIA is not the first approach to formalising the aspects and concepts of business processes, it is more ambitious in the following respects: Firstly, it is independent from particular...... modelling formalisms of business processes and it is designed in such a way that any formalism for modelling some aspect of a business process can be plugged into AMFIBIA. Therefore, AMFIBIA is formalism-independent. Secondly, it is not biased toward any aspect of business processes; the different aspects...... can be considered and modelled independently of each other. Moreover, AMFIBIA is not restricted to a fixed set of aspects; new aspects of business processes can be easily integrated. Thirdly, AMFIBIA does not only name and relate the concepts of business process modelling, as it is typically done...

Optimization method concerning target conflicts between safety aspects and occupational safety aspects in nuclear power plant operations

International Nuclear Information System (INIS)

Mueller, W.

1991-01-01

The simplified cost-benefit analysis has not been considered for applications in nuclear engineering with complex decisions between safety aspects and occupational safety aspects. The extended cost-benefit analysis encounters problems with non-monetary criteria. Solutions are in sight, however with a subjective element. A major problem in implementing the method is the psychological barrier as against an evaluation of human life. The multi-attribute utility analysis overcomes the difficulties of the extended cost-benefit analysis, however, it also creates new problems on account of the complicated construction of the utility functions. The problems are solved most elegantly with the multi-criteria outranking analysis, the only disadvantage possibly being less transparency at first sight. (orig./HP) [de

Two often disregarded aspects of Foucault's pendulum

International Nuclear Information System (INIS)

Pérez, José-Philippe; Pujol, Olivier

2015-01-01

This paper revisits the famous Foucault's pendulum by highlighting two often-disregarded aspects in mechanics courses. The first one concerns the existence of a local accelerated reference frame to express the law of dynamics without the Coriolis force. The second aspect deals with the geometrical phase that appears in pendulum dynamics. This last point, which could appear banal, should be related to analogous consideration in quantum physics. It is also linked to vectorial parallel transport of the pendulum angular momentum eigenvector. Numerical simulations with MATLAB are proposed. (paper)

[Gender (role) aspects in doctor-patient communication].

Science.gov (United States)

Sieverding, M; Kendel, F

2012-09-01

Aspects of gender and gender roles are important factors influencing the interactions between physicians and their patients. On the one hand, gender roles have an impact on the behavior of the patients, such as in health care utilization or use of preventive examinations. On the other hand, gender issues influence doctors' actions with respect to communication, diagnosis, and treatment. Here, a gender bias may lead to misdiagnosis and inadequate treatment. In this paper certain pertinent aspects of gender roles in the doctor-patient relationship are discussed and illustrated by empirical findings.

Several cities in Indonesia have the sewerage local regulation such as Banjarmasin, Bantul, Surakarta and Denpasar. Meanwhile, The National Government have guideline in composing domestic sewerage regulation. Each city have their own characteristic and issues that need to be carried out by the local regulation. By using SWOT analysis, this study tries to figure out several aspect that need to be included in the local regulation. International references from developed and developing countries like Japan, Phillipines, Malaysia and Thailand were also used as benchmark without neglecting the local conditions of cities in Indonesia. Several crucial aspect of local regulation are institutional authority, composition on-site and off-site system, tariff, evaluation and monitoring, as well as punishment and rewards. Both tariff and evaluation aspects need to be narrowed down into specific regulations.

Economic aspects of radionuclide production for nuclear medicine

Le Gallic, Y.; Prospert, J.

1980-03-01

In a difficult economic situation it was considered advisable to inform users of certain financial aspects of radionuclide production for nuclear medicine. Two aspects of this vast and many-sided problem are developed here: - The cost price structure of different products (radiopharmaceutical and radioimmunological) which defines the size of the market consistent with a balanced budget. This aspect of the economic analysis seems all the more important as ORIS, although a non profit-making organization, has to balance its production costs. - The effects on the national economy of the nuclear medicine supply market. From this viewpoint it seemed interesting to examine the share-out of the French market between ORIS which is practically the only national producer and importers, as well as the balance of payments situation in this respect [fr

Ethical aspects on rare diseases.

Barrera, Luis A; Galindo, Gilberto Cely

2010-01-01

In this chapter we discuss several of the most relevant subjects related to ethics on Rare Diseases. Some general aspects are discussed such as the socio-psychological problems that confront the patients and their families that finally lead to marginalization and exclusion of patients affected by these diseases from the health programs, even in wealthy countries. Then we address problems related to diagnosis and some ethical aspects of newborn screening, prenatal, pre-implantation diagnosis and reference centers, as well as some conditions that should be met by the persons and institutions performing such tasks. Alternatives of solutions for the most critical situations are proposed. Subsequently the orphan drugs subject is discussed not only from the availability point of view, prizes, industrial practices, and purchasing power in developed and developing societies. The research related to rare disease in children and other especially vulnerable conditions, the need for informed consent, review boards or ethics comities, confidentiality of the information, biobanks and pharmacogenetics are discussed.

Aspect-object alignment with Integer Linear Programming in opinion mining.

Directory of Open Access Journals (Sweden)

Yanyan Zhao

Full Text Available Target extraction is an important task in opinion mining. In this task, a complete target consists of an aspect and its corresponding object. However, previous work has always simply regarded the aspect as the target itself and has ignored the important "object" element. Thus, these studies have addressed incomplete targets, which are of limited use for practical applications. This paper proposes a novel and important sentiment analysis task, termed aspect-object alignment, to solve the "object neglect" problem. The objective of this task is to obtain the correct corresponding object for each aspect. We design a two-step framework for this task. We first provide an aspect-object alignment classifier that incorporates three sets of features, namely, the basic, relational, and special target features. However, the objects that are assigned to aspects in a sentence often contradict each other and possess many complicated features that are difficult to incorporate into a classifier. To resolve these conflicts, we impose two types of constraints in the second step: intra-sentence constraints and inter-sentence constraints. These constraints are encoded as linear formulations, and Integer Linear Programming (ILP is used as an inference procedure to obtain a final global decision that is consistent with the constraints. Experiments on a corpus in the camera domain demonstrate that the three feature sets used in the aspect-object alignment classifier are effective in improving its performance. Moreover, the classifier with ILP inference performs better than the classifier without it, thereby illustrating that the two types of constraints that we impose are beneficial.

Aspects of leak before break quantification in pressurized pipes

International Nuclear Information System (INIS)

Hellen, R.A.J.; Darlaston, B.J.L.; Connors, D.C.

1980-01-01

In fitness for purpose studies of pressurized structures containing defects, the concept of leak before break is often invoked. As the assumptions used in the concept are sometimes very pessimistic it is desirable to be able to quantify them more precisely. Two aspects are currently receiving attention; these are the way in which a crack profile develops during fatigue and what happens when the remaining ligament below the crack fails. These aspects are being evaluated experimentally and theoretically. Data are presented from tests on pipes subjected to cyclic pressure and subsequently failed. An analytical approach is proposed on the question of ligament failure, this being based on the development of some recent work on flat plates. The overall question of leak before break is considered. As the understanding and confidence increases, it is possible to reduce the range of interest and focus on specific aspects of the problem. This paper examines these aspects. (author)

ITER plasma control design solutions and performance requirements are strongly driven by its nuclear mission, aggressive commissioning constraints, and limited number of operational discharges. In addition, high plasma energy content, heat fluxes, neutron fluxes, and very long pulse operation place novel demands on control performance in many areas ranging from plasma boundary and divertor regulation to plasma kinetics and stability control. Both commissioning and experimental operations schedules provide limited time for tuning of control algorithms relative to operating devices. Although many aspects of the control solutions required by ITER have been well-demonstrated in present devices and even designed satisfactorily for ITER application, many elements unique to ITER including various crucial integration issues are presently under development. We describe selected novel aspects of plasma control in ITER, identifying unique parts of the control problem and highlighting some key areas of research remaining. Novel control areas described include control physics understanding (e.g., current profile regulation, tearing mode (TM) suppression), control mathematics (e.g., algorithmic and simulation approaches to high confidence robust performance), and integration solutions (e.g., methods for management of highly subscribed control resources). We identify unique aspects of the ITER TM suppression scheme, which will pulse gyrotrons to drive current within a magnetic island, and turn the drive off following suppression in order to minimize use of auxiliary power and maximize fusion gain. The potential role of active current profile control and approaches to design in ITER are discussed. Issues and approaches to fault handling algorithms are described, along with novel aspects of actuator sharing in ITER.

Grammatical Aspect and Gesture in French: A kinesiological approach

Доминик Бутэ

2016-12-01

Full Text Available In this paper, we defend the idea that research on Gesture with Speech can provide ways of studying speakers’ conceptualization of grammatical notions as they are speaking. Expressing an idea involves a dynamic interplay between our construal, shaped by the sensori-motoric and interactive experiences linked to that idea, the plurisemiotic means at our disposal for expressing it, and the linguistic category available for its expression in our language. By analyzing the expression of aspect in Speech with Gesture (GeSp in semi-guided oral interactions, we would like to make a new contribution to the field of aspect by exploring how speakers’ construal of aspectual differences grammaticalized in their language, may be enacted and visible in gesture. More specifically we want to see the degree to which event structure differences expressed in different grammatical aspects (perfective and imperfective correlate with kinesiological features of the gestures. To this end, we will focus on the speed and flow of the movements as well as on the segments involved (fingers, hand, forearm, arm, shoulder. A kinesiological approach to gestures enables us to analyze the movements of human bodies according to a biomechanical point of view that includes physiological features. This study is the first contribution focused on the links between speech and gesture in French in the domain of grammatical aspect. Grammatical aspect was defined by Comrie (1976 [1989] as involving the internal unfurling of the process, «[...] tense is a deictic category, i.e. locates situations in time, usually with reference to the present moment [...]. Aspect is not concerned with relating time of the situation to any other time-point, but rather with the internal temporal constituency of the one situation; one could state the difference as one between situation-internal time (aspect and situation-external time (tense » (Comrie, 1976 [1989]: 5.

What’s Done is Done: Verb Aspect and Verbatim Memory

Directory of Open Access Journals (Sweden)

Meghan Salomon-Amend

2017-09-01

Full Text Available Grammatical verb aspect uses morphosyntactic cues (‘-ed’, ‘-ing’ to convey whether an action is, for example, complete (“walked” or on-going (“was walking” and has shown notable comprehension ramifications for a reader’s event model. Additionally, research suggests that the reader quickly forgets verbatim surface-form information, such as morphosyntactic cues, while the event model remains intact. The current study used three different memory tests to probe readers’ event models of the texts, testing readers’ event model at retrieval. More importantly, we explored whether participants could have biased memory for the perfective aspect consistent with events unfolding in the narrative world. We show that verbs in the perfective aspect were remembered more accurately than those in the imperfective aspect. Moreover, imperfective verbs had a stronger tendency to be misremembered as being in the perfective aspect. That is, readers’ memory seems to be affected by the passage of narrative time, rather than maintaining fidelity to the temporal status of the verb at original presentation.

Aspect-Oriented Model-Driven Software Product Line Engineering

Science.gov (United States)

Groher, Iris; Voelter, Markus

Software product line engineering aims to reduce development time, effort, cost, and complexity by taking advantage of the commonality within a portfolio of similar products. The effectiveness of a software product line approach directly depends on how well feature variability within the portfolio is implemented and managed throughout the development lifecycle, from early analysis through maintenance and evolution. This article presents an approach that facilitates variability implementation, management, and tracing by integrating model-driven and aspect-oriented software development. Features are separated in models and composed of aspect-oriented composition techniques on model level. Model transformations support the transition from problem to solution space models. Aspect-oriented techniques enable the explicit expression and modularization of variability on model, template, and code level. The presented concepts are illustrated with a case study of a home automation system.

Highlights: • Nanocell lattice with a high aspect ratio on InSb semiconductor surface was fabricated by ion beam irradiation. • The fabrication technique consisting of top-down and bottom-up processes was performed in FIB. • High aspect ratio of 2 was achieved in nanocell lattice with a 100 nm interval. • The intermediate-flux irradiation is favorable for fabrication of nanocell with a high aspect ratio. - Abstract: A high aspect ratio nanocell lattice was fabricated on the InSb semiconductor surface using the migration of point defects induced by ion beam irradiation. The fabrication technique consisting of the top-down (formation of voids and holes) and bottom-up (growth of voids and holes into nanocells) processes was performed using a focused ion beam (FIB) system. A cell aspect ratio of 2 (cell height/cell diameter) was achieved for the nanocell lattice with a 100 nm dot interval The intermediate-flux ion irradiation during the bottom-up process was found to be optimal for the fabrication of a high aspect ratio nanocell.

Full Text Available Objective To investigate the correlation between the Alberta Program Early CT Score (ASPECTS and the Scandinavian Stroke Scale (SSS for the evaluation of neurological impairment in patients with acute stroke. Method 59 patients with a first acute ischemic stroke were evaluated. The ASPECTS were evaluated by 2 neurologists at admission and by another neurologist after 48 hours. The NIHSS and SSS was applied to determinate stroke severity. Correlations and agreements were analysed statistically by Spearman and Kappa tests. Results ASPECTS was correlated with National Institute of Health Stroke Scale (NIHSS at admission (r = -0.52; p < 0.001 and SSS (r = 0.50; p < 0.001. The ASPECTS and SSS items were most correlated with arm (r = 0.52; p < 0.001 and hand (r = 0.49; p < 0.001 motor power, and speech (r = 0.51; p < 0.001. The SSS of 25.5 shows sensitivity (68% and specificity (72% when associated with ASPECTS ≤ 7. Conclusion The SSS can predict worst neurological impairment when associated with lower values of ASPECTS.

Myocardial Na,K-ATPase: Clinical aspects

Science.gov (United States)

Kjeldsen, Keld

2003-01-01

The specific binding of digitalis glycosides to Na,K-ATPase is used as a tool for Na,K-ATPase quantification with high accuracy and precision. In myocardial biopsies from patients with heart failure, total Na,K-ATPase concentration is decreased by around 40%; a correlation exists between a decrease in heart function and a decrease in Na,K-ATPase concentration. During digitalization, around 30% of remaining pumps are occupied by digoxin. Myocardial Na,K-ATPase is also influenced by other drugs used for the treatment of heart failure. Thus, potassium loss during diuretic therapy has been found to reduce myocardial Na,K-ATPase, whereas angiotensin-converting enzyme inhibitors may stimulate Na,K pump activity. Furthermore, hyperaldosteronism induced by heart failure has been found to decrease Na,K-ATPase activity. Accordingly, treatment with the aldosterone antagonist, spironolactone, may also influence Na,K-ATPase activity. The importance of Na,K pump modulation with heart disease, inhibition in digitalization and other effects of medication should be considered in the context of sodium, potassium and calcium regulation. It is recommended that digoxin be administered to heart failure patients who, after institution of mortality-reducing therapy, still have heart failure symptoms, and that the therapy be continued if symptoms are revealed or reduced. Digitalis glycosides are the only safe inotropic drugs for oral use that improve hemodynamics in heart failure. An important aspect of myocardial Na,K pump affection in heart disease is its influence on extracellular potassium (Ke) homeostasis. Two important aspects should be considered: potassium handling among myocytes, and effects of potassium entering the extracellular space of the heart via the bloodstream. It should be noted that both of these aspects of Ke homeostasis are affected by regulatory aspects, eg, regulation of the Na,K pump by physiological and pathophysiological conditions, as well as by medical

QCD-instantons at LHC. Theoretical aspects

2007-06-01

Instantons are nonperturbative, topologically nontrivial field configurations, which occur in every nonabelian gauge theory. They can be understood as tunneling processes between topologically distinct vacua. Although being a basic theoretical aspect of the Standard Model, a direct experimental verification of instanton processes is still lacking. In this thesis the general discovery potential for QCD-instantons at the LHC is studied in detail by means of instanton perturbation theory. In this context the close correspondence between the leading instanton induced processes at HERA and at LHC becomes important. Essential aspects and differences to deep inelastic scattering can already be revealed by studying the simplest process. Based on these results inclusive cross sections are calculated including the emission of final state gluons. Compared to deep inelastic scattering, a large enhancement of the cross section is found.

New Vehicle Detection Method with Aspect Ratio Estimation for Hypothesized Windows

Directory of Open Access Journals (Sweden)

Jisu Kim

2015-12-01

Full Text Available All kinds of vehicles have different ratios of width to height, which are called the aspect ratios. Most previous works, however, use a fixed aspect ratio for vehicle detection (VD. The use of a fixed vehicle aspect ratio for VD degrades the performance. Thus, the estimation of a vehicle aspect ratio is an important part of robust VD. Taking this idea into account, a new on-road vehicle detection system is proposed in this paper. The proposed method estimates the aspect ratio of the hypothesized windows to improve the VD performance. Our proposed method uses an Aggregate Channel Feature (ACF and a support vector machine (SVM to verify the hypothesized windows with the estimated aspect ratio. The contribution of this paper is threefold. First, the estimation of vehicle aspect ratio is inserted between the HG (hypothesis generation and the HV (hypothesis verification. Second, a simple HG method named a signed horizontal edge map is proposed to speed up VD. Third, a new measure is proposed to represent the overlapping ratio between the ground truth and the detection results. This new measure is used to show that the proposed method is better than previous works in terms of robust VD. Finally, the Pittsburgh dataset is used to verify the performance of the proposed method.

Molen, Yara Fleury; Carvalho, Luciane Bizari Coin; Prado, Lucila Bizari Fernandes do; Prado, Gilmar Fernandes do

2014-01-01

Insomnia involves difficulty in falling asleep, maintaining sleep or having refreshing sleep. This review gathers the existing informations seeking to explain insomnia, including those that focus on psychological aspects and those considered neurobiological. Insomnia has been defined in psychological (cognitive components, such as worries and rumination, and behavioral aspects, such as classic conditioning) and physiological terms (increased metabolic rate, with increased muscle tone, heart rate and temperature). From the neurobiological point of view, there are two perspectives: one which proposes that insomnia occurs in association with a failure to inhibit wakefulness and another that considers hyperarousal as having an important role in the physiology of sleep. The non-pharmacological interventions developed to face different aspects of insomnia are presented.

Phenomenological aspects of unified theories

International Nuclear Information System (INIS)

Peccei, R.D.

1987-01-01

The author briefly discusses two new phenomena of recent interest, the 5/sup th/ force and variant axions. The former, for its elucidation, will require further gravitational experiments, but the author concludes that variant axions are now definitely rules out experimentally. Various aspects of superstring phenomenology are then addressed, including some of the generic predictions of superstrings and some of its generic problems. In particular, he discusses some of the phenomenological consequences of having an extra Z 0 boson and the circumstances under which this excitation is a genuine prediction of superstrings. Since it is likely that a more reliable relic of superstrings will be provided by the presence of superpartners at low energy (≤ TeV), he discusses some of the bounds for squarks and gluinos obtained at the SppS collider and the expectations for their production at the Tevatron. As a final topic, he touches upon some of the consequences that result from having the Fermi scale arise from an underlying theory. Some aspects of the composite Higgs model and of the strongly coupled standard model are briefly reviewed

Investigating legal aspects of cyberbullying.

Paul, Simone; Smith, Peter K; Blumberg, Herbert H

2012-11-01

In the UK schools are required by law to protect students from bullying; the responsibility of teachers to govern such behaviour has been extended outside the school setting to include cyberbullying. In this investigation, cyberbullying in secondary education is explored from the student perspective using a qualitative method of enquiry. Reported awareness and understanding about the legal aspects of cyberbullying are investigated; consideration is given to legislation, cybercrime, children's rights, school sanctions and safeguarding responsibilities. A total of 197 male and female students aged between 11 and 14 years old participated. Despite the availability of information on guidelines and legislation at national, local, and school level, this does not appear to have reached ground level of the individual student. There is a considerable gap between what students should know and what they report to be aware of with regard to legal aspects of cyberbullying. To address concerns of keeping up with the pace of change in cyberbullying, a collaborative approach is required with young people and adults sharing expertise.

Thermophysical aspects of WWER safety

Kolochko, Vladimir N.

1999-01-01

The paper presents a review of the main thermophysical aspects of NPPs safety and efficiency increase applied to WWERs. Improvement of operating WWER units is the main short-term and medium-term tasks of the utilities in Ukraine. The new generation of reactors for increasing the reactor facilities efficiency should utilize achievements of thermo physics research results. The thermophysical aspects of NPPs safety and efficiency are envisaged in the context of the atomic energy development strategy. The analysis of thermophysical processes occurring in the core shows that a number of problems concerning boiling crisis and heat exchange intensification during transient and accidents are not solved in spite of numerous calculations and experimental research. The up-to-date safety conception includes severe accidents consideration for safety assessment. Review of severe accidents management is presented. Additional validation of the West advanced thermal hydraulic codes which are applied for WWERs reassessment calculations is required. Contribution of the processes which might occur in WWER containment to safety problems solving is considered as well. (author)

In situ leaching of uranium: Technical, environmental and economic aspects

International Nuclear Information System (INIS)

1989-01-01

Within the framework of its activities in nuclear raw materials the International Atomic Energy Agency has convened a series of meetings to discuss various aspects of uranium ore processing technology, recovery of uranium from non-conventional resources and development of projects for the production of uranium concentrates including economic aspects. As part of this continuing effort to discuss and document important aspects of uranium production the IAEA convened a Technical Committee Meeting on Technical, Economic and Environmental Aspects of In-Situ Leaching. Although the use of this technique is limited by geological and economic constraints, it has a significant potential to produce uranium at competitive prices. This is especially important in the current uranium market which is mainly characterised by large inventories, excess production capability and low prices. This situation is not expected to last indefinitely but it is unlikely to change drastically in the next ten years or so. This Technical Committee Meeting was held in Vienna from 3 to 6 November 1987 with the attendance of 24 participants from 12 countries. Eight papers were presented. Technical sessions covered in-situ mining research, environmental and licensing aspects and restoration of leached orebodies; the technological status of in-situ leaching, the current status and future prospects of in-situ leaching of uranium in Member States, general aspects of planning and implementation of in-situ projects and the economics of in-situ leaching.

2013-07-01

Full Text Available Grammatical aspect is known to shape event understanding. However, little is known about how it interacts with other important temporal information, such as recent and distant past. The current work uses computer-mouse tracking (Spivey, Grosjean, & Knoblich, 2005 to explore the interaction of aspect and temporal context. Participants in our experiment listened to past motion event descriptions that varied according to aspect (simple past, past progressive and temporal distance (recent past, distant past while viewing scenes with paths and implied destinations. Participants used a computer mouse to place characters into the scene to match event descriptions. Our results indicated that aspect and temporal context interact in interesting ways. When aspect placed emphasis on the ongoing details of the event and the temporal context was recent (thus, making fine details available in memory, this match between conditions elicited smoother and faster computer mouse movements than when conditions mismatched. Likewise, when aspect placed emphasis on the less-detailed end state of the event and temporal context was in the distant past (thus making fine details less available, this match between conditions also elicited smoother and faster computer mouse movements.

Energy and social aspects

International Nuclear Information System (INIS)

Perez, D.; Gomez, Y.

2008-01-01

In this section, the social aspects of Cuba's energy system are described, based on the accessibility and availability of energy services and the affordability and acceptance of these energy services by the population. Accessibility refers to the existence of modern energy services and supporting infrastructures that allow the population, regardless of income level, place of residence, race, religion, etc., the use of modern fuels. Logistics and the economy determine the amount and kinds of energy and energy services available in each place. Even if energy services are accessible to the population, problems with their availability during particular time periods may exist; thus, this section discusses the problems of availability of modern fuels in Cuba. Affordability relates to the ability of the population to pay for the energy services that are accessible and available. Energy prices should be low enough (without affecting the profitability of the producing companies) to enable everyone's minimum requirements for modern energy services to be satisfied. Acceptability concerns the social and/or environmental problems related to energy chains, ranging from production and use to the disposal of waste generated by energy production. Making an assessment of the acceptability of an energy option is often difficult and sometimes involves many issues, including social, environmental, cultural, economic and religious aspects at local and regional levels

Adili, Fatemeh; Larijani, Bagher; Haghighatpanah, Mohammadreza

2006-11-01

This study was undertaken to consider the psychological aspect of diabetes with regard to improving clinical outcomes. The review was limited to literature reports on the causes, solutions, and treatments of some common psychological problems known to complicate diabetes management. A literature search was undertaken using Pub-Med, CINAHL, Proquest, Elsevier, Blackwell Synergy, Ovid, Ebsco, Rose net, and Google websites, including studies published in English journals between 1995 and 2006. Therefore about 88 articles were selected based on the inclusion criteria. In earlier studies, relatively little empirical research was found to substantiate the effect of psychological counseling in complicated diabetes. The greatest deficits were seen in areas of mental health, self-esteem parent impact, and family cohesion. There were some different factors, which influence the psychological aspect of diabetic patients, such as age, gender, place of living, familial and social support, motivation, energy, life satisfaction, and lifestyle. There are various types of solutions for coping with the psychological problems in diabetic clients. The most essential solution lies in educating the patients and healthcare providers on the subject. Before initiating each educational intervention, a thorough assessment would be crucial. Treatment plans may benefit from cognitive behavior therapy (CBT), behavior family therapy, improving family communication, problem-solving skills, and providing motivation for diabetic patients. Moreover, it seems that the close collaboration between diabetologists and psychologists would be fruitful.

Weisberg, Yanna J; Deyoung, Colin G; Hirsh, Jacob B

2011-01-01

This paper investigates gender differences in personality traits, both at the level of the Big Five and at the sublevel of two aspects within each Big Five domain. Replicating previous findings, women reported higher Big Five Extraversion, Agreeableness, and Neuroticism scores than men. However, more extensive gender differences were found at the level of the aspects, with significant gender differences appearing in both aspects of every Big Five trait. For Extraversion, Openness, and Conscientiousness, the gender differences were found to diverge at the aspect level, rendering them either small or undetectable at the Big Five level. These findings clarify the nature of gender differences in personality and highlight the utility of measuring personality at the aspect level.

Designing for the handicapped persons, aiming at the liquidation of the barriers is actually an essential part of the architects activity. It results from the fact that the handicapped persons issue became the interdisciplinary one. The architect, being responsible for the living space and environment creation, is to design the friendly environment for the handicapped persons. The space favourable for the handicapped is favourable for all. There are many aspects of the designing for the handicapped; legislative or execution issues are the examples. The legislative aspect is presented in this paper on the base of the contemporary legal rules of the Polish Republic, whereas the execution aspect is introduced and discussed on the basis of the two projects designed by the Design Bureau in Cracow and being currently in realization. These are: housing & service unit (Boruty-Spiechowicza Str., Cracow) and the Faculty of Philosophy complex at the Jesuits College (Kopernika Str., Cracow).

2003-05-01

Full Text Available This research analyzes the issue from the jurisprudential and social aspects. The social aspect focuses on the existing viewpoints regarding the grounds for addiction and also looks into the jurisprudential decrees by Shiite and Sunni jurisprudents regarding opium, hashish and tobacco. In other words, the research focuses on the impacts of jurisprudential decrees on social issues and vice-versa. The research in order to offer strong proof for subjects under discussion conducts documental studies and extracts jurisprudential, historical and scientific texts. In all, this research promotes one’s knowledge about the chronology of drugs including opiates, hashish and tobacco, their side effects, reasons behind drug addiction and jurisprudential decrees in this regard from the viewpoint of jurisprudents. From the viewpoint of social philosophy it raises the thought that there is a dialectic relationship between the thought and the environment and necessitates the need for changes in jurisprudential thoughts. As far as is applied aspect is concerned, it offers solutions for preventing drug addiction.

Distinguishing Relational Aspects of Character Strengths with Subjective and Psychological Well-being

Full Text Available Research has shown that character strengths are positively linked with well-being in general. However, there has not been a fine-grained analysis up to date. This study examines the individual relational aspects between the 24 character strengths, subjective well-being (SWB, and different aspects of psychological well-being (PWB at two times of measurement (N = 117. Results showed that overall the “good character” was significantly stronger related with PWB than with SWB. The character strength “hope” was at least moderately correlated with the PWB aspects meaning, optimism and autonomy, and “zest” with the PWB aspects relationships and engagement. “Persistence” showed the highest correlation with the PWB aspect mastery. Out of the 24 character strengths, the happiness-related strengths (hope, zest, gratitude, curiosity, and love were more likely to correlate with PWB and SWB than any other character strength. This study offers a more fine-grained and thorough understanding of specific relational aspects between the 24 character strengths and a broad range of well-being aspects. Future studies should take up a detailed strategy when exploring relationships between character strengths and well-being.

Aspect-related Vegetation Differences Amplify Soil Moisture Variability in Semiarid Landscapes

Science.gov (United States)

Yetemen, O.; Srivastava, A.; Kumari, N.; Saco, P. M.

2017-12-01

Soil moisture variability (SMV) in semiarid landscapes is affected by vegetation, soil texture, climate, aspect, and topography. The heterogeneity in vegetation cover that results from the effects of microclimate, terrain attributes (slope gradient, aspect, drainage area etc.), soil properties, and spatial variability in precipitation have been reported to act as the dominant factors modulating SMV in semiarid ecosystems. However, the role of hillslope aspect in SMV, though reported in many field studies, has not received the same degree of attention probably due to the lack of extensive large datasets. Numerical simulations can then be used to elucidate the contribution of aspect-driven vegetation patterns to this variability. In this work, we perform a sensitivity analysis to study on variables driving SMV using the CHILD landscape evolution model equipped with a spatially-distributed solar-radiation component that couples vegetation dynamics and surface hydrology. To explore how aspect-driven vegetation heterogeneity contributes to the SMV, CHILD was run using a range of parameters selected to reflect different scenarios (from uniform to heterogeneous vegetation cover). Throughout the simulations, the spatial distribution of soil moisture and vegetation cover are computed to estimate the corresponding coefficients of variation. Under the uniform spatial precipitation forcing and uniform soil properties, the factors affecting the spatial distribution of solar insolation are found to play a key role in the SMV through the emergence of aspect-driven vegetation patterns. Hence, factors such as catchment gradient, aspect, and latitude, define water stress and vegetation growth, and in turn affect the available soil moisture content. Interestingly, changes in soil properties (porosity, root depth, and pore-size distribution) over the domain are not as effective as the other factors. These findings show that the factors associated to aspect-related vegetation

Tenses, Aspects, and Categories of Evidentiality and Egocentricity in Spoken Lhasa Tibetan

Directory of Open Access Journals (Sweden)

Jiang Di

2007-10-01

Full Text Available This paper mainly discusses verbal aspects and their syntactic markers in Lhasa Tibetan. Since aspects in Tibetan always share markers with other important categories called evidentiality and egocentricity, the former of which assesses the evidence of speaker's statement and the latter denotes behavioral characteristics of a speaker's ego-centricity, this paper simultaneously describes all three types: aspect, evidentiality and egocentricity. There are nine types of verb aspects in Lhasa Tibetan, namely: Prospective, Imminent, Premediated, Realis, Durative, Resultative, Merely-past, Perfect, and Contextual aspects. There are four types of evidentialities, namely, Self-knowledge, Knowing-by-sight, Knowing-by-newly-found-information and Knowing-by-inference evidentialities. Categories of egocentricity demonstrate whether an action is towards the Self or the Other, whether the speaker gains or loses, and so on. Additionally，this essay also discusses the interactive relationship between syntactical verb aspects and personal pronouns, intentionality, modality, as well as temporal-spatial cognition.

Bam earthquake was the most catastrophic natural disasters in recent years. The aim of this study was to review different aspects of crisis management during and after the catastrophic earthquake in Bam City, Iran. Data needed for this systematic review were collected through searching PubMed, EMBASE and SID databases, for the period from 2003 to 2011. Keywords included earthquake, Iran and Bam earthquake. The data were summarized and were analyzed using Content Analysis. Out of 422 articles, 25 articles were included in the study. Crisis Management aspects and existing pitfalls were classified into seven categories including planning and organization, human resource management, management of logistics, international humanitarian aids, field performance of the military and security forces, health and medical service provision, and information management. Positive aspects and major pitfalls of crisis management have been introduced in all the mentioned categories. The available evidence indicated poor crisis management during Bam earthquake that resulted in aggravating the losses as well as diminishing the effect of interventions. Thus, concerning the importance of different aspects of the crisis management and the high prevalence of disasters in Iran, the observed vulnerability in disaster management process should be addressed.

Linguistic aspects of writing for professional purposes

Greta Përgjegji

2016-03-01

Full Text Available Writing for Professional Purposes is considered as a means of communication between professionals who belong to two communities that have different languages, but share the same knowledge or expertise. The article gives a hint on how writing for specific purposes evolved to give rise to the creation of Writing for Professional Purposes. The social, cultural and cognitive aspects are an essential part of Writing for Professional Purposes since the physical act of writing cannot be considered only a result or product of the knowledge the individual possesses but also a social and cultural act. Therefore, the social and cultural aspects of writing explains the specificities and the intricacies of the effects these aspects have on writing for it is considered as an inseparable part of social and cultural groups. On the other hand, the cognitive aspect of writing explains and emphasizes the mental activities of the individual during the decision-making process while he/she is writing planning and editing their material having in mind the audience. On the same line of reasoning, writing for professional purposes in a second language means that the writer has to consider the audience twice; first, there is an audience who shares the same knowledge or expertise and second, the audience does not have the same language. Consequently, writing in another language that is not the first language with a specific jargon as well as a specific grammatical structure brings about a lot of difficulties. Hence, writing in professional contexts in the mother tongue implies only writing in a specialized version of a language already known to the writer, but writing in a target language means that the writer has to learn the target language and the specialized version of that language.

Special radiation protection aspects of medical accelerators

CERN Document Server

Silari, Marco

2001-01-01

Radiation protection aspects relevant to medical accelerators are discussed. An overview is first given of general safety requirements. Next. shielding and labyrinth design are discussed in some detail for the various types of accelerators, devoting more attention to hadron machines as they are far less conventional than electron linear accelerators. Some specific aspects related to patient protection are also addressed. Finally, induced radioactivity in accelerator components and shielding walls is briefly discussed. Three classes of machines are considered: (1) medical electron linacs for 'conventional' radiation therapy. (2) low energy cyclotrons for production of radionuclides mainly for medical diagnostics and (3) medium energy cyclotrons and synchrotrons for advanced radiation therapy with protons or light ion beams (hadron therapy).

2016-01-01

In wastewater treatment facilities (WWTF), technical and financial aspects have been considered a priority, while other issues, such as social aspects, have not been evaluated seriously and there is not an accepted methodology for assessing it. In this work, a methodology focused on social concerns related to WWTF is presented. The methodology proposes the use of 25 indicators as a framework for measuring social performance to evaluate the progress in moving towards sustainability. The methodology was applied to test its applicability and effectiveness in two WWTF in Mexico (urban and rural). This evaluation helped define the key elements, stakeholders and barriers in the facilities. In this context, the urban facility showed a better overall performance, a result that may be explained mainly by the better socioeconomic context of the urban municipality. Finally, the evaluation of social aspects using the semi-qualitative approach proposed in this work allows for a comparison between different facilities and for the identification of strengths and weakness, and it provides an alternative tool for achieving and improving wastewater management. - Highlights: • The methodology proposes 25 indicators as a framework for measuring social performance in wastewater treatment facilities. • The evaluation helped to define the key elements, stakeholders and barriers in the wastewater treatment facilities. • The evaluation of social aspects allows the identification of strengths and weakness for improving wastewater management. • It provides a social profile of the facility that highlights the best and worst performances.

The quality of a conventional radiographic image can be characterized in terms of five basic parameters; density, contrast, latitude, resolution and noise. Since xeroradiographic images exhibit very limited broad area contrasts, and image formation is predominantly due to edge enhancement, a straightforward description of image quality using the same five parameters is not adequate. A detailed study was made of the radiographic aspects of xeroradiography with special reference to mammography, and a summary of major findings to date with appropriate references to published papers is presented

Nouzil, Ibrahim; Raza, Ali; Pervaiz, Salman

2017-09-01

Sustainable development has been recognized globally as one of the major driving forces towards the current technological innovations. To achieve sustainable development and attain its associated goals, it is very important to properly address its concerns in different aspects of technological innovations. Several industrial sectors have enjoyed productivity and economic gains due to advent of automation technology. It is important to characterize sustainability for the automation technology. Sustainability is key factor that will determine the future of our neighbours in time and it must be tightly wrapped around the double-edged sword of technology. In this study, different impacts of automation have been addressed using the ‘Circles of Sustainability’ approach as a framework, covering economic, political, cultural and ecological aspects and their implications. A systematic literature review of automation technology from its inception is outlined and plotted against its many outcomes covering a broad spectrum. The study is more focused towards the social aspects of the automation technology. The study also reviews literature to analyse the employment deficiency as one end of the social impact spectrum. On the other end of the spectrum, benefits to society through technological advancements, such as the Internet of Things (IoT) coupled with automation are presented.

High β(β much-gt ε/q 2 ) large aspect ratio (ε much-gt 1) tokamak equilibria are shown to be always stable to ideal M.H.D. modes that are localized about a flux surface. Both the ballooning and interchange modes are shown to be stable. This work uses the analytic high β large aspect ratio tokamak equilibria developed by Cowley et.al., which are valid for arbitrary pressure and safety factor profiles. The stability results make no assumption about these profiles or the shape of the boundary. 14 refs., 4 figs

Some aspects of nuclear fuel economics

International Nuclear Information System (INIS)

Timm, M.

1975-01-01

The paper reviews the economic aspects of nuclear fuel based on the year 1975. The focus of attention is on the well-established light-water reactors, which for the time being, and also for the foreseeable future, account for the bulk of the world's nuclear power capacity. The author describes the principal economic aspects of the light-water fuel cycle components and discusses their future development to the extent that this can be foreseen. Various approaches to the formulation of the contract for the supply of light-water fuel are discussed on the basis of the established procedure. After some introductory comments on methods of calculating specific fuel costs, the author describes the main results of fuel cycle calculations. The economic aspects of nuclear fuel for other types of reactors are discussed in the sequence in which it is planned to introduce such reactors commercially. The economic data available apply to reactors ranging from the heavy-water-moderated type, through helium-cooled high-temperature reactors, to the fast breeders, and are based more and more on results of feasibility studies and less on practical operational experience. For this reason the author discusses only the basic data of importance, as viewed from the present-day stand-point, and mentions the emerging trends. It should be pointed out, however, that a comprehensive description of this kind can only show the situation at a given moment. Numerous political, economic and technological influences are in a state of permanent flux, hence economic data and developments may easily change within a short time. (author)

Nutritional Aspects of Dysphagia Management.

Science.gov (United States)

Gallegos, C; Brito-de la Fuente, E; Clavé, P; Costa, A; Assegehegn, G

This chapter describes the nutritional aspects of dysphagia management by starting with the definition of these two conditions (dysphagia and malnutrition) that share three main clinical characteristics: (a) their prevalence is very high, (b) they can lead to severe complications, and (c) they are frequently underrecognized and neglected conditions. From an anatomical standpoint, dysphagia can result from oropharyngeal and/or esophageal causes; from a pathophysiological perspective, dysphagia can be caused by organic or structural diseases (either benign or malignant) or diseases causing impaired physiology (mainly motility and/or perception disorders). This chapter gathers up-to-date information on the screening and diagnosis of oropharyngeal dysphagia, the consequences of dysphagia (aspiration pneumonia, malnutrition, and dehydration), and on the nutritional management of dysphagic patients. Concerning this last topic, this chapter reviews the rheological aspects of swallowing and dysphagia (including shear and elongational flows) and its influence on the characteristics of the enteral nutrition for dysphagia management (solid/semisolid foods and thickened liquids; ready-to-use oral nutritional supplements and thickening powders), with special focus on the real characteristics of the bolus after mixing with human saliva. © 2017 Elsevier Inc.

Full Text Available Emergency radiological diagnosis of acute ischaemic stroke requires the accurate detection and appropriate interpretation of relevant imaging findings. Non-contrast computed tomography (CT provides fast and low-cost assessment of the early signs of ischaemia and is the most widely used diagnostic modality for acute stroke. The Alberta Stroke Program Early CT Score (ASPECTS is a quantitative and clinically validated method to measure the extent of ischaemic signs on brain CT scans. The CE-marked electronic-ASPECTS (e-ASPECTS software automates the ASPECTS score. Anglia Ruskin Clinical Trials Unit (ARCTU independently carried out a clinical investigation of the e-ASPECTS software, an automated scoring system which can be integrated into the diagnostic pathway of an acute ischaemic stroke patient, thereby assisting the physician with expert interpretation of the brain CT scan. Here we describe a literature review of the clinical importance of reliable assessment of early ischaemic signs on plain CT scans, and of technologies automating these processed scoring systems in ischaemic stroke on CT scans focusing on the e-ASPECTS software. To be suitable for critical appraisal in this evaluation, the published studies needed a sample size of a minimum of 10 cases. All randomised studies were screened and data deemed relevant to demonstration of performance of ASPECTS were appraised. The literature review focused on three domains: i interpretation of brain CT scans of stroke patients, ii the application of the ASPECTS score in ischaemic stroke, and iii automation of brain CT analysis. Finally, the appraised references are discussed in the context of the clinical impact of e-ASPECTS and the expected performance, which will be independently evaluated by a non-inferiority study conducted by the ARCTU.

Understanding the influence of aspect ratio on water immersion into silica nanoholes is of significant importance to the etching process of semiconductor fabrication and other water immersion-related physical and biological processes. In this work, the processes of water immersion into silica nanoholes with different height/width aspect ratios (ϕ = 0.87, 1.92, 2.97, 4.01, 5.06) and different numbers of water molecules (N = 9986, 19972, 29958, 39944) were studied by molecular dynamics simulations. A comprehensive analysis has been conducted about the detailed process of water immersion and the influence of aspect ratios on water immersion rates. Five distinguishable stages were identified for the immersion process with all studied models. The results reveal that water can easily immerse into the silica nanoholes with larger ϕ and smaller N. The calculation also suggests that aspect ratios have a greater effect on water immersion rates for larger N numbers. The mechanism of the water immersion process is discussed in this work. We also propose a mathematical model to correlate the complete water immersion process for different aspect ratios.

Hauptbeschreibung Aspect-oriented-programming is a relatively new technique that has evolved on top of the already well-established approach of object-oriented programming. When it is used correctly, it promises to remove many redundant parts of a code that appear repeatedly in an application, essentially untangling the original code. Thus, it can lead to a cleaner, more separated software design, to greater modularity and maintainability. Time-savings in software engineering can also be huge cost-savings, and anything that increases software quality is a welcome sight in an industr

Tang, Haixiong; Zhou, Zhi; Sodano, Henry A

2014-04-23

The aspect ratio of barium titanate (BaTiO3) nanowires is demonstrated to be successfully controlled by adjusting the temperature of the hydrothermal growth from 150 to 240 °C, corresponding to aspect ratios from 9.3 to 45.8, respectively. Polyvinylidene fluoride (PVDF) nanocomposites are formed from the various aspect ratio nanowires and the relationship between the dielectric constant of the nanocomposite and the aspect ratio of the fillers is quantified. It was found that the dielectric constant of the nanocomposite increases with the aspect ratio of the nanowires. Nanocomposites with 30 vol % BaTiO3 nanowires and an aspect ratio of 45.8 can reach a dielectric constant of 44.3, which is 30.7% higher than samples with an aspect ratio of 9.3 and 352% larger than the polymer matrix. These results demonstrate that using high-aspect-ratio nanowires is an effective way to control and improve the dielectric performance of nanocomposites for future capacitor applications.

In this paper, we discuss some design aspects of transuranic field studies. Some of the principal steps in the design of such studies are given and illustrated using examples. This is followed by a review of sampling designs that have been used at nuclear detonation and safety-shot sites on the Nevada Test Site and elsewhere for estimating spatial pattern and total amounts in soil. Some design aspects of ecosystem-type transuranic studies for estimating total amounts as well as movement of transuranics between ecosystem components are also discussed. Acceptance sampling using either attributes or measurements is considered as a possible approach for deciding whether to clean up a contaminated site. Three general guidelines for the design of efficient transuranic studies are presented

This study was designed to explore two aspects (mother-father; woman-man) of Masculinity-Femininity in personality. Sixty-five middle school students, 150 high school students and 219 university students were asked to rate the desirability for them, their fathers and mothers, and society of each of 45 items comprising a questionnaire which described valid characteristics of these two aspects. Analysis of the results revealed that male subjects in all age groups seemed to feel that their fathers desired them to be more masculine (i.e., father and man) than they, themselves, desired. Those of high school and university age also seemed to feel that their mothers and fathers and society desired more motherliness of them than they, themselves, desired. Female high school and university subjects seemed to feel that their fathers and mothers desired much more femininity (mother and woman) and much less masculinity (father and man) than they, themselves, desired.

We describe the intricacies of instrumentation of the Java class library and present an extended instrumentation approach allowing the user to choose between a pure Java weaving solution based on a two-phases instrumentation scheme, or a single-phase one requiring a tiny native code layer. The single-phase approach allows to better isolate the weaving process from the execution of the woven code.

criterio para juzgar la confiabilidad de un sistema electrico de potencia, es la frecuencia y duracion de la interrupcion del suministro de energia electrica a los consumidores. Debido a la importancia de mantener la continuidad del servicio de energia electrica, es necesario estudiar los dispositivos de proteccion contra sobretensiones, ya que en condiciones meteorologicas adversas, asi como por condiciones de cambio de configuracion en la red, se pueden presentar sobretensiones que danen a los equipos del sistema electrico de potencia. Los apartarrayos son dispositivos cuya funcion es proteger equipos de un sistema electrico de potencia contra las sobretensiones, por medio de absorcion de energia a traves del sistema de aterrizamiento. En la proteccion de los Sistemas Electricos de Potencia (SEP) contra sobretensiones comunmente se empleaban los apartarrayos de carburo de silicio (SiC) que brindaban un margen de proteccion pequeno. En los ultimos anos se han desarrollado nuevas tecnologias que han revolucionado la coordinacion del aislamiento. Un ejemplo de estas tecnologias es la aplicacion de los apartarrayos de oxidos metalicos (ZnO), los cuales incrementan el margen de proteccion considerablemente. En este trabajo se evaluan las limitaciones y potencialidades reales de los modelos existentes, y el propuesto en este trabajo, de apartarrayos de oxidos metalicos, con la ayuda de las simulaciones digitales en transitorios electromagneticos, cuando los apartarrayos estan sujetos a transitorios por maniobra de interruptores como por descargas atmosfericas. Todas las simulaciones en este trabajo se realizaron con el Programa de Transitorios Electromagneticos (EMTP), que es una herramienta ampliamente usada y recomendada para el analisis de los fenomenos transitorios electromagneticos. El modelado de los apartarrayos de oxidos metalicos en el EMTP es complicado por el comportamiento no lineal de sus elementos y se requiere de una gran precision y cuidado para implementar

Effect of aspect ratio in free-swimming plunging flexible plates

Science.gov (United States)

Yeh, Peter; Alexeev, Alexander

2015-11-01

Using three dimensional fully-coupled fluid-structure interaction simulations, we investigate the free swimming of plunging elastic rectangular plates with aspect ratios ranging from 0.5 to 5 in a viscous fluid with Reynolds number 250. We find that maximum velocity occurs near the first natural frequency regardless of aspect ratio, while the maximum swimming economy occurs away from the first natural frequency and corresponds to a specific swimmer bending pattern characterized by reduced displacement of the swimmer's center of mass. Furthermore, we find that swimmers with wider span are both faster and more economical than narrow swimmers. These faster speeds are due to decreased drag for low aspect ratio plunging swimmers, which is in agreement with a recently proposed vortex-induced drag model that suggests that the smaller relative size of side vortices in low aspect ratio swimmers creates less drag per unit width. Our results are useful for the design of small autonomous micro-swimming devices and also provide insights on the physics of aquatic locomotion using oscillating fins.

Determination of dough properties is also mentioned and pasta quality is also described in this chapter. Chemometrics-multivariate analysis is one of the analyses carried out. Regarding production weighing/mixing of flours, kneading, extruded wheat flours, and sodium chloride are important processing steps/raw materials used in the manufacturing of pastry products. Staling of cereal-based products is also taken into account. Finally, safety aspects of cereal-based products are well documented with special emphasis on mycotoxins, acrylamide, and near infrared methodology.

Aspect-Aided Dynamic Non-Negative Sparse Representation-Based Microwave Image Classification

Directory of Open Access Journals (Sweden)

Xinzheng Zhang

2016-09-01

Full Text Available Classification of target microwave images is an important application in much areas such as security, surveillance, etc. With respect to the task of microwave image classification, a recognition algorithm based on aspect-aided dynamic non-negative least square (ADNNLS sparse representation is proposed. Firstly, an aspect sector is determined, the center of which is the estimated aspect angle of the testing sample. The training samples in the aspect sector are divided into active atoms and inactive atoms by smooth self-representative learning. Secondly, for each testing sample, the corresponding active atoms are selected dynamically, thereby establishing dynamic dictionary. Thirdly, the testing sample is represented with ℓ 1 -regularized non-negative sparse representation under the corresponding dynamic dictionary. Finally, the class label of the testing sample is identified by use of the minimum reconstruction error. Verification of the proposed algorithm was conducted using the Moving and Stationary Target Acquisition and Recognition (MSTAR database which was acquired by synthetic aperture radar. Experiment results validated that the proposed approach was able to capture the local aspect characteristics of microwave images effectively, thereby improving the classification performance.
