    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.

    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.

    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

    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.

    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.

    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)

    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)

    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

    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

    The current regulation, established by NOM-229-SSA1-2002 standard, {sup T}echnical requirements for facilities, health responsibilities, technical specifications for equipment and facilities for radiation protection in medical diagnosis with X-rays,{sup t}hat should be credited refresher courses, and training in radiation safety in accordance with current regulations, however, has been observed that the assistance and accreditation of courses is basically to cover administrative and regulatory requirements and therefore does not necessarily cover needs of the patient to radiation protection in the use of old and new technologies. 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

    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

    In the Peru, according to the current regulations, people that work with ionizing radiations should have an authorization (individual license), which is granted by the Technical Office of the National Authority that is the technical body of the Instituto Peruano de Energia Nuclear (IPEN) manager of the control of ionizing radiations in the country. The individual license is obtained after the applicant fulfills the requested requirements, as having safety knowledge and radiological protection. Since its founding in 1972, the Centro Superior de Estudios Nucleares (CSEN) of the IPEN has carried out diverse training courses in order to that people can work in a safe way with ionizing radiations in medicine, industry and research, until the year 2013 have been organized 2231 courses that have allowed the training of 26213 people. The courses are organized according to the specific work that is carried out with radiations (medical radio-diagnostic, dental radiology, nuclear medicine, radiotherapy, industrial radiography, nuclear meters, logging while drilling, etc.). In their majority the courses are directed to people that will make use of radiations for first time, but refresher courses are also granted in the topic. The CSEN also carries out the Master degree programs highlighting the Second Professional Specialization in Radiological Protection carried out from the year 2004 with the support of the National University of Engineering. To the present has been carried out 2 programs and there is other being developed. In this work is shown the historical evolution of the radiological protection courses as well as the important thing that they are to work in a safe way in the country. (Author)

    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.

    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 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)

    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 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 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 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.

    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.

    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)

    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.

    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)

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.

    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.

    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.

    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)

    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)

    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 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.

    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.

    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.

    Physical protection against the theft or unauthorized diversion of nuclear materials and against the sabotage of nuclear facilities by individuals or groups has long been a matter of national and international concern. Although responsibility for establishing and operating a comprehensive physical protection system for nuclear materials and facilities within a State rests entirely with the Government of that State, it is not a matter of indifference to other States whether and to what extent that responsibility is fulfilled. Physical protection has therefore become a matter of international concern and co-operation. The need for international cooperation becomes evident in situations where the effectiveness of physical protection in one State depends on the taking by other States also of adequate measures to deter or defeat hostile actions against nuclear facilities and materials, particularly when such materials are transported across national frontiers [French] La proteccion fisica contra el robo o la desviacion no autorizada de materiales nucleares y contra el sabotaje de las instalaciones nucleares por parte de individuos o de grupos ha sido durante largo tiempo motivo de preocupacion nacional e internacional.

    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.

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.

    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)

    In the last years the organizations in charge of the regulation in matter of radiological protection, its have adopted measures to minimize the risks derived of the medical exposures, paying special attention to those that involve women in age of procreation, gestating and in period of lactation, because the embryo - fetus and the newborn babies ones are very vulnerable to the risks of the ionizing radiations, which can end up producing them multiple effects of variable severity. In Cuba, a Maternal-children program that includes the genetic advice to the pregnant woman from the medical point of view exists but didn't so the evaluation of the radiological risk; which is only carried out by the Medical Surveillance Service of the Protection and Hygiene of the Radiations Center (CPHR), without that mediates an official link among both parts and whose existence is only known by a reduced group of professionals of the health and of specialists in Radiological Protection. On the other hand is not established a strategy at national level for the differentiated information and systematic in these topics that it contributes to the control of the exposures of the embryo fetus and the breast-fed baby. Keeping in mind the above-mentioned the specialists of the CPHR have elaborated a proposal of national program for the radiological protection of the embryo- fetus due to the medical exposure of its progenitor. In the same one it is settles down the interrelation between work groups and multidisciplinary institutions to achieve the detection, communication and consultant ship of the cases of exposure to the fetus or breast-fed baby that happen in the country and at the same time include the training so much of the professionals of the health like of the public in general.

    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)

    Enclosed or intra-continental seas should be distinguished from lakes, because the systems of the international law of the sea and international water- law differ from each other. The definitions of the enclosed sea used in the literature are not satisfactory and in the paper a new and more appropriate definition is proposed. The main sources of the international law of the sea are four Conventions adopted by the United Nations Conference on the Law of the Sea held at Geneva in 1958. Many of the problems concerning the Baltic are also characteristic of other intra-continental seas. In the paper reference is made to these problems and to the considerations that render the provisions of the Conventions on the Law of the Sea inadequate for the case of the enclosed seas. With regard to the prevention of pollution of the sea and the disposal of radioactive wastes, the rules of international law are still undeveloped. In the paper mention is made of the aspects that should be considered when drawing up regulations and taking measures for the prevention of pollution, especially of the enclosed seas.

    Full Text Available Las producciones de régimen continuo, como las empresas de níquel, requieren del trabajo estable de los Sistemas Eléctricos de Potencia (SEP frente a las averías, por lo que la instalación de protecciones que actúen u operen solo cuando éstas ocurran, desconectando rápidamente la zona o equipo averiado, se hace necesaria para evitar la propagación del daño por todo el SEP. El funcionamiento inadecuado de las protecciones incrementa los costos de producción en una industria; para garantizar el buen funcionamiento de las mismas se requieren herramientas como los simuladores digitales de protección. Este artículo trata de la modelación y simulación de las protecciones eléctricas que utilizan los transformadores de potencia en dos industrias niqueleras cubanas. Mediante el empleo de una Biblioteca Virtual de Protecciones Eléctricas creada en MATLAB/SIMULINK, se analiza el comportamiento de los sistemas de protecciones instalados en ambas industrias, se detectan deficiencias y se ofrecen las soluciones adecuadas para evitar tanto el aumento de los costos de mantenimiento como las desconexiones inoportunas u operaciones incorrectas.

    Full Text Available Determinar las ganancias solares en el vano-ventana con protecciones solares y analizar el comportamiento térmico en un edificio es un tema relativamente nuevo en el ámbito chileno. No obstante, el inadecuado manejo del control solar, en algunos casos, genera problemas de sobrecalentamiento al interior de la edificación. Esta investigación busca establecer un procedimiento que permita evaluar cuatro tipos de protecciones solares y analizar sus implicancias energéticas en un edificio público, cuya infraestructura utilizada se justifica en el desconocimiento de nuevas exigencias que hará el Estado para este tipo de edificación. Para el caso de estudio se han determinado 37 escenarios con distintos factores solares modificados, definidos a través de cálculo manual, los cuales son evaluados bajo simulación dinámica (TAS. En primera instancia se analiza el comportamiento de dos recintos y posteriormente se obtienen los resultados en relación con la demanda energética del edificio. Las protecciones solares utilizadas (voladizos, retranqueo, lamas horizontales y verticales reducen la demanda de refrigeración de un 52 a 73% (aumentando la demanda de calefacción, sin embargo la demanda energética total (calefacción y refrigeración disminuye de un 24 a 31%.

    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

    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 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.

    Recent recommendations by the European Union (2004) for performing lateral cranial cephalometry (LCC) state that collimation should be maximized so that only those tissues necessary are irradiated when performing clinical diagnoses, although the fact that many manufacturers do not incorporate these elements in their equipment design has been recognised (recommendations 4f). Aim: the manufacture and utilization of a collimator with a pre-patient compensating filter for LLC which may be used in most extraoraldental radiology units, as well as determining the reduction in the dose of radiation absorbed by more sensitive tissues exposed to said clinical exploration. Making use of mannequins, phantom and craniums, we constructed a collimator with a compensating filter and established the necessary technical, dosimetric and quality specifications for its clinical use. Subsequently, we studied 16 patients referred for cephalometric study, determining the radiation dose (TLDs) in both the patients (crystalline lens, frontal lobe, parotid/submaxillary/thyroid glands and brain) and in the radiographic film, as well as in different parts of the collimator/filter. Al presented we are aiming for its clinical use by carrying out LCC in another 16 patients referred of orthodontic treatment but with the pre-a patient introduction of the tested collimator with the compensating filter as a substitute for the usual technique. The collimation reduced the field or radiation by some 40% and with that, so too the radiated tissues. The compensating filter reduced the dose in tissues by some 34.2. Our collimator has allowed the radiological image to be obtained with only one third the usual radiation dose. The dose reaching the film shies only between 17% less than in the usual technique and didn't alter its diagnostic capacity. A reduction of 61,6% of the dose administered to the patient is achieved by incorporating the collimator and filter to most radiological equipment without the need for renovating or substituting existing apparatus.

Aim: the manufacture and utilization of a collimator with a pre-patient compensating filter for LLC which may be used in most extraoraldental radiology units, as well as determining the reduction in the dose of radiation absorbed by more sensitive tissues exposed to said clinical exploration. Making use of mannequins, phantom and craniums, we constructed a collimator with a compensating filter and established the necessary technical, dosimetric and quality specifications for its clinical use. Subsequently, we studied 16 patients referred for cephalometric study, determining the radiation dose (TLDs) in both the patients (crystalline lens, frontal lobe, parotid/submaxillary/thyroid glands and brain) and in the radiographic film, as well as in different parts of the collimator/filter. Al presented we are aiming for its clinical use by carrying out LCC in another 16 patients referred of orthodontic treatment but with the pre-a patient introduction of the tested collimator with the compensating filter as a substitute for the usual technique. The collimation reduced the field or radiation by some 40% and with that, so too the radiated tissues. The compensating filter reduced the dose in tissues by some 34.2. Our collimator has allowed the radiological image to be obtained with only one third the usual radiation dose. The dose reaching the film shies only between 17% less than in the usual technique and didn't alter its diagnostic capacity. A reduction of 61,6% of the dose administered to the patient is achieved by incorporating the collimator and filter to most radiological equipment without the need for renovating or substituting existing apparatus.

    The work presents the physical and radiological protection procedures involved in radiotherapy performed in patients during pregnancy that contribute to the security and development of the fetus. We analyzed clinical cases studies with confirmed pregnancy undergoing radiotherapy. The study also analyzed the dosimetry protocols specific to different treatment fields considering the absorbed dose in the region estimated fetal through experimental measurements and computer simulations presented in the literature. It is discussed the concepts of radiation fetuses presented in the Report of the AAPM TG 36 focusing on the influence of the use of appropriate shielding and peripheral dose distribution outside the primary radiation field. Studies show no consensus on the threshold dose for fetal exposure, with values ranging between 2 and 25 cGy, depending on gestational age and position within the abdomen. As recommended by the organs of radiological protection in Brazil, the equivalent dose of radiation to the abdomen of pregnant women occupationally exposed should not exceed 2.0 mSv for the entire period of pregnancy. The measurements show that the main factors contributing to the increase in dose to the fetus are: radiation trail head, scattering from the collimator and dispersion by tissue irradiated region to the region surrounding the fetus. The results of research and clinical situations illustrated in reviewed scientific articles indicate that radiotherapy in pregnant patients is feasible, provided that the dose to the fetus is less than the threshold values, which can be achieved by the use of screens and settings fields Radiation appropriate and properly planned by experts who should simulate physical prior to treatment. The work aims to contribute to subsidize the treatment decision in radiotherapy procedures in pregnant patients pointing out the risks and benefits when the need for treatment. (author)

    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 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.

    After the terrorist attack in New York, USA, in 2001, there was a worldwide concern about possible attacks using radioactive material in conventional detonators, called as Radiological Dispersal Device (RDD) or 'dirty bomb'. Several studies have been and are being made to form a global knowledge about this type of event. As until now, fortunately, there has not been an event with RDD, the Goiania Radiological Accident in Brazil, 1987, is used as a reference for decision-making. Several teams with technical experts should act in an event with RDD, but the medical staffs who respond quickly to the event must be properly protected from the harmful effects of radiation. Based on the radiological protection experts performance during the Goiania accident and the knowledge from lessons learned of many radiological accidents worldwide, this work presents an adaptation of the radiation protection actions for an event with RDD that helps a medical team as primary responders. The following aspects are presented: the problem of radioactive contamination from the explosion of the device in underground environment, the actions of the first responders and evaluation of health radiation effects. This work was based on specialized articles and papers about radiological accidents and RDD; as well as personal communication and academic information of the Institute of Radiation Protection and Dosimetry. The radiation protection actions, adapted to a terrorist attack event with RDD, have as a scenario a subway station in the capital. The main results are: the use of the basic radiation protection principle of time because there is no condition to take care of a patient keeping distance or using a shielding; the use of full appropriate protection cloths for contaminating materials ensuring the physical safety of professionals, and the medical team monitoring at the end of a medical procedure, checking for surface contamination. The main conclusion is that all medical actions

    Since the discovery of X-rays in 1895, ionizing radiation has been applied in many sectors of society, such as medicine, industry, safety, construction, engineering and research. However, population is unaware of both the applications of ionizing radiation and their risks and benefits. It can be seen that most people associate the terms 'radiation' and 'nuclear energy' with the atomic bomb or cancer, most likely because of warlike applications and the stealthy way radioactivity had been treated in the past. Thus, it is necessary to clarify the population about the main aspects related to the applications, risks and associated benefits. These knowledge can be disseminated in schools. Brazilian legislation for basic education provides for topics such as nuclear energy and radioactivity to high school students. However, some factors hamper such an educational practice, namely, few hours of class, textbooks do not address the subject, previous concepts obtained in the media, difficulty in dealing with the subject in the classroom, phobia, etc. One solution would be the approximation between schools and institutions that employ technologies involving radioactivity, which would allow students to know the practices, associated radiological protection, as well as the risks and benefits to society. Currently, with the increasing application of ionizing radiation, especially in medicine, it is necessary to demystify the use of radioactivity. (author)

    The perspective of patient protection at the Radio neurosurgery National Service of the Social Security Mexican Institute is divided into three parts: the testing program for equipment acceptance, an assurance quality program based on periodic tests, an also other assurance quality based on tests during the application. Among the technical aspects that influence in the equipment acceptance tests, it is the collimation type, the characteristics of the lineal accelerator, the platform for planning and the network type. In the case of the collimation system and the accelerator characteristics, we consider the manufacturer's specifications and requirements of Mexican Official Standard NOM-033-NUCL-1999, {sup T}echnical Specifications for the Teletherapy Units Operation, Linear Accelerators{sup .} Planning for the platform takes into account the manufacturer's specifications. In the case of computed tomography as well as review the calibration according to manufacturer's specifications should be considered the standard NOM-229-SSA1-2002. In the case of the linear accelerator must be the radiological characterization of radiation beam as part of this, the absolute dose determination. As for the periodic tests is verified the dose constancy, as well as the flattening and symmetry of X-rays beam. There are also tests battery with daily, monthly and yearly frequencies, which make up the assurance quality program. (Author)

  13. 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.

    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 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

    Full Text Available Previous studies concerned with neuropsychological aspect of delusions, were mainly focused on specific forms of this disorder. Comparatively small number of investigations were concerned with cognitive deficiencies accompanying the delusions. The substance of this study includes the detection of neuropsychological disfunctions in patients with persistent delusion disorder, and in tracing of these cognitive distortions to appropriate brain regions. Besides, characteristics of attribution style in these patients are analysed, from the aspect of their connections with unadjusted localized input for their reasoning system. The investigation is designed as a comparative study. The sample includes: a group of patients with persistent delusion disorder; a group of patients with paranoid schizophrenia; a group of healthy individuals. The participants have been tested by a neuropsychological battery that represents the following cognitive functions: attention, memory, vizuospatial and vizuoconstruction organization, executive ability, verbal divergent thinking. Projective Rorschach's method was used for estimation of attribution style.

  4. 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.

    Ethics can be defined as a reflection on nature and a definition of “the good”. Individuals value qualities and things dissimilarly, most visibly, but they also value their goods in different ways, in different relations to each other, for different reasons, and to different ends. These differences are very applicable to sustainability. In other words, sustainability cannot be achieved without attention to its ethical dimensions. The aim of this research is to examine the ethical aspects of s...

    The increase of bundle supply has become widespread in several sectors (for instance in telecommunications and energy fields). This paper review relates strategic aspects of bundling. The main purpose of this paper is to analyze profitability of bundling strategies according to the degree of competition and the characteristics of goods. Moreover, bundling can be used as price discrimination tool, screening device or entry barriers. In monopoly case bundling strategy is efficient to sort consumers in different categories in order to capture a maximum of surplus. However, when competition increases, the profitability on bundling strategies depends on correlation of consumers' reservations values. (author)

    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

    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

    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.

    The impact of natural disasters in cities and communities has grown by different causes in different parts of the world. There are several examples of the impact that have caused extreme natural events in facilities and activities in which ionizing radiation are used. The recent example of the accident at the nuclear power plant of Fukushima Daichi with release of radioactive substances to the environment caused by an earthquake and a tsunami show the need of the increasing improvement in the safety of facilities and activities that use ionizing radiation and radioactive materials in general. Planning and response to events of this nature is another aspect that is important and needs attention. The IAEA documents offer a comprehensive and effective guide to achieve an appropriate degree of readiness to respond to nuclear and radiological emergencies in any situation. However, there are specific challenges for planning and response posed a radiological emergency caused by an extreme natural event or occurring simultaneously with this. The present work deals with essential aspects to take into account by the authorities who coordinate the planning and response to radiological emergencies to deal with extreme natural events.

    2017-09-01

    Full Text Available In the process of globalization of world economic processes, the role of individual national economies increases, comparative advantages of the development of a country are formed, and their competitiveness is ensured. That is why it is worth emphasizing the importance of increasing the competitiveness of each individual country, based on its internal capacity. In a broad aspect, the competitiveness of the national economy is perceived as the ability of the country to ensure the balance of its external proportions and to avoid those constraints imposed by the foreign economic sphere, to self-organizing the improvement of their world economic ties. The competitiveness of the economy at the macro level is associated with the duration of the cycle of reproduction of the main productive assets and, accordingly, the jobs, productive forces of society and determined by the overall economic efficiency of investment. The criteria of competitiveness of the national economy are the growth of social productivity of labor, increase of social and economic efficiency of production and standard of living of the population. The competitiveness of the national economy determines sustainable socio-economic development of the country, as well as sustainable development predetermines the competitiveness of not only the country, but also all its levels. Scientific results are obtained using special methods of research of economic objects and phenomena, that is, based on the correlation and regressive, comparative analysis (establishing the relationship between the indicator factor, as well as economic modeling. Findings. Generalizing analysis and the importance of the macroeconomic aspect of competitiveness were used in the research paper, which will allow to better respond to the economic situation, in accordance with the trends of the “green” transformation of the economy; which in turn will solve important problems of the development and implementation of its

The federal government was very interested in developing the North because they saw oil and gas development in the North as a means of strengthening sovereignty claims. The projected profits from Northern oil and gas development were also very attractive, and after dealing with environmental and social concerns, the government granted the necessary drilling permits. The federal government also made allowances for huge tax incentives for the oil and gas companies to encourage exploration. Although oil has been found, large-scale production in the Beaufort Sea never materialized. During the period from 1984 to 1988, world prices for oil fell and it was no longer economical to undertake frontier production. Beaufort Sea operation were shut down as the oil industry changed its focus to more cost-effective reservoirs in southern Canada. 1 fig

    Full Text Available The concept of resilience has represented during the recent years a leading concern both in Romania, within the European Union and worldwide. Specialists in economics, management, finance, legal sciences, political sciences, sociology, psychology, grant a particular interest to this concept. Multidisciplinary research of resilience has materialized throughout the time in multiple conceptualizations and theorizing, but without being a consensus between specialists in terms of content, specificity and scope. Through this paper it is intended to clarify the concept of resilience, achieving an exploration of the evolution of this concept in ecological, social and economic environment. At the same time, the paper presents aspects of feedback mechanisms and proposes a formalization of resilience using the logic and mathematical analysis.

    Full Text Available Customer loyalty - is a voluntary user solution for a long time to build relationships with the company. Loyalty is the user's desire for a long time to continue their relationship with a particular company, because loyal customers are those who purchase goods/services of the company from time to time. Loyalty can be treated as a customer desire, willingness to be a regular customer for a long time, buying and using the goods of the chosen companies by recommending them to friends and colleagues. Loyalty can be seen as a multi-dimension, covering behavioral and positional components, where positional aspect reflects customers' approach to business, while the behavioral dimension reveals a frequent and regular shopping, purchase quantity, size, range, availability, etc.

    1997-01-01

    Beside the technical problems of ADTT which remain to be solved it is crucial for the ADTT progress that safety and economical aspects are considered already during the research and planning phases. Safety here stands for the converse of risk, negative consequences for human life and health and the environment together with the corresponding probabilities. The system to be considered includes all phases of an ADTT plant, a life cycle analysis (LCA). The risk analysis is useful for two purposes: comparison with other ways of handling nuclear waste, e.g. geological repository and for valuation of different construction designs. Due to lack of precise plans and adequate data the analysis will be more of a qualitative than quantitative type. The main risks appear in connection with repair and replacement work. 2 refs., 1 fig

    Full Text Available Burn injuries and their subsequent treatment cause one of the most excruciating forms of pain imaginable. The psychological aspects of burn injury have been researched in different parts of the world, producing different outcomes. Studies have shown that greater levels of acute pain are associated with negative long-term psychological effects such as acute stress disorder, depression, suicidal ideation, and post-traumatic stress disorder for as long as 2 years after the initial burn injury. The concept of allostatic load is presented as a potential explanation for the relationship between acute pain and subsequent psychological outcomes. A biopsychosocial model is also presented as a means of obtaining better inpatient pain management and helping to mediate this relationship.

    Full Text Available Infertility can be defined as a crisis with cultural, religious, and class related aspects, which coexists with medical, psychiatric, psychological, and social problems. Relation between psychiatric and psychological factors stem from a mutual interaction of both. Family is an important institution in maintaining human existence and raising individuals in line with society's expectations. Fertility and reproduction are seen as universal functions unique to women with raising children as the expected result of the family institution. Incidence of infertility has increased recently and can become a life crisis for a couple. Even though not being able to have a child affects both sexes emotionally, women feel greater amounts of stress, pressure, anxiety, and depression.Consequences of infertility arise from short and long-term devastating effects on both individual's physical and mental health, and marital system. Many studies focus on infertility related psychological and psychiatric disorders (depression, anxiety, grief, marital conflict, gender differences, relation between the causes of infertility and psychopathology, the effects of psychiatric evaluation and intervention -when necessaryon the course of infertility treatment, pregnancy rates, and childbirth. The most important underlying causes of high levels of stress and anxiety that infertile women experience are the loss of maternity, reproduction, sense of self, and genetic continuity. In this review article is to investigate the relationship between medically unexplained symptoms and psychiatric symptoms.

    Full Text Available Innovation in assisted reproductive technologies together with increased infertility and new family structures are increasing the use of gestational surrogacy as a means to have children. Before, during and after the process, it is necessary to study the psychosocial characteristics of triad members: the gestational surrogate, intended parents, and offspring. Research has indicated positive adaptation to the process and benefits for all members of the triad. Altruism is the main motivation of surrogates. Notably, psychological well-being has been found to be higher in individuals who have become parents through surrogacy than in those who have used egg donation or have followed a natural process of conception. Moreover, no differences in psychosocial characteristics have been observed in the offspring, compared with children born through natural conception or egg donation. Results highlight the positive aspects of surrogacy. Future research should investigate psychosocial factors that modulate the process, acting as risk and protective factors for well-being of the triad members, and identify the optimal profiles of surrogates for the process to be a success.

    2016-01-01

    Full Text Available The paper considers risk in the context of the main characteristics of non-classical epistemology. It states that non-classical epistemology is characterized by transformation, according to which the major priority of cognitive activity shifts the focus from the present to the past. In this situation a subject is keen not on what he or she has learnt but on what can be learnt. Truth being a crucial criterion of scientific knowledge is becoming of less priority, while risk is becoming more and more significant and acts as one of the major epistemology measurements. Risk is gaining the status of epistemological phenomenon, which shows a growing degree of uncertainty as a cognitive process background and the necessity for a subject to learn the world (make decisions under the conditions of uncertainty degree strengthening. The author states that risk is a comprehensive notion and it obtains a base value for all other aspects of its application, specifically, in the role of epistemological phenomenon.

    Precise computation of neutron flux in the core of a nuclear reactor represents one of the basic aspects of reactor design and operation. Neutron flux is computed by solving Boltzmann`s linear equation. Anyway, the direct solution of the equation involves too great a number of operations for practical application, leading up to TeraFlops or even PetaFlops supercomputing capabilities. Physical and mathematical models are then required to handle the extensive variety of configurations encountered. Numerical methods must be adapted to the rapid evolution of computer power, as also computer architecture: sequential, vector or parallel. Physical and mathematical models must allow for very fast estimation for online control and monitoring, adequate quantification for industrial studies and high-precision, best estimate computations. Coupling of neutronics to mechanics and two-phase flow thermohydraulics must be implemented in order to improve the accuracy in best-estimate computation schemes and to take into account the transient behaviour of the plant during normal operation or incidents. In this field of continuous improvement, the new methods applied in Reactor Physics lead obviously to good results and provide the improvements required in the future for the needs of efficiency, safety and advanced fuel cycle. This trend and the ``evolutionary`` implementation in large and modular software systems will be illustrated by the example of the SAPHYR system. (authors). 3 tabs.

    Full Text Available Reconstruction of the penis in transgender operations, amputation of the penis, congenital deformities and anomalies of the penis was and remains today an important issue in plastic surgery of the urogenital region. The only method to restore the penis is phalloplasty. In general, over the past decades, generations of clinicians have different ways and flaps for total fallouretheral reconstruction. Thus was formulated the characteristics of an ideal flap for the formation of neophallos, which should be safe, sensitive, without hair, and with long leg. However, despite the fact that the characteristics of a perfect flap, nowadays there is no “gold standard” in the formation of neophallos, as phalloplasty is a fairly complicated surgery, and the choice of method depends on many factors. The choice of methodology is determined by the plastics surgeon and to each patient is individual, depends on the etiology of the disease and the possibility of choosing the form of the donor’s transplant. This article presents a literature review devoted to the historical aspects of phalloplasty. In the article, in chronological order reflected the evolution of the different forming methods neofallos, phallourethrоplasty, describes their advantages and disadvantages.

  6. [Economic aspects of epilepsy].

    Argumosa, A; Herranz, J L

    2000-06-01

    The economic magnitude of epilepsy is determined by its effect on the employment status of the patients, the cost of drug treatment for them and the healthcare system and the repercussion worldwide. Studies of the cost of the disease show that it has economic importance due to the sum of the direct and indirect costs caused by it. In the case of epilepsy, the results of studies in various countries led to the creation of a Commission on Economic Aspects of Epilepsy. The lack of epidemiological studies regarding epilepsy in Spain may explain the lack of publications on this subject in our country. The percentage of the total cost due to antiepileptic drugs is considerable and will probably increase in the future. The pharmaco-economic evaluation made by cost-benefit, cost-effectiveness, cost-usefulness analysis and studies to minimize costs should serve to use healthcare resources in the most effective manner and justify the rational use of the new antiepileptic drugs. The economic impact of epilepsy is added to the repercussion of the disease itself on the patient and his family. The different distribution of costs in children and adults with epilepsy suggest the need for intervention at an early age to try to reduce the long term economic and personal repercussions. The pharmaco-economic evaluation of the new antiepileptic drugs will make it clear whether their considerable cost is worth paying for their greater effectivity.

  7. Electrical aspects of rainout

    International Nuclear Information System (INIS)

    Rosenkilde, C.E.

    1981-01-01

    Rainout commonly denotes the aggregate of phenomena associated with precipitation scavenging of radioactivity from a cloud of nuclear debris that is within a natural rain cloud. (In contrast, the term, washout, is applicable when the nuclear cloud is below the rain cloud and the term, fallout, commonly denotes the direct gravitational settling of contaminated solid material from a nuclear cloud.) Nuclear debris aerosols may be scavenged within natural clouds by a variety of different physical processes which may involve diffusion, convection, impaction, nucleation, phoresis, turbulence, and/or electricity among others. Processes which involve electrical aspects are scrutinized for their susceptibility to the intimate presence of the radioactive-cloud environment. This particular choice of electrical processes is not accidental. Nearly all of the listed processes were examined earlier by Williams. His rough estimates suggested that electrical effects, and to a lesser extent turbulence, could enhance the scavenging of those submicron aerosols which reside in the size-range that bridges the minimum in the scavenging rate coefficient which is commonly called the Greenfield gap. This minimum in the scavenging-rate coefficient is created by the simultaneous reduction of scavenging via diffusion and the reduction of scavenging via inertial impaction. However, Williams omitted the specific influence of a radioactive environment. This report aims to remedy this omission

  8. Cultural Aspects of Suicide

    Full Text Available Undefined cultural factors cannot be dismissed and significantly contribute to the worldwide incidence of death by suicide. Culture is an all embracing term and defines the relationship of an individual to his environment. This study seeks to investigate the effect of culture on suicide both regionally and internationally. Culture-bound syndrome with suicidal behaviours specific to a particular culture or geographical region are discussed. Opinions are divided as to the status of religious martyrs. The law itself is silent on many aspects of suicidal behaviour and despite decriminalization of suicide as self-murder, the latter remains on the statutes of many developing countries. The Caribbean region is of concern due to its steady rise in mean suicide rate, especially in Trinidad and Tobago where socio-cultural factors are instrumental in influencing suicidal behaviour. These include transgenerational cultural conflicts, psycho-social problems, media exposure, unemployment, social distress, religion and family structure. The methods used are attributed to accessibility and lethality. Ingestion of poisonous substances is most popular followed by hanging. The gender differences seen with regard to suicidality can also be attributed to gender related psychopathology and psychosocial differences in help-seeking behaviour. These are influenced by the cultural environment to which the individual is exposed. Culture provides coping strategies to individuals; as civilization advances many of these coping mechanisms are lost unclothing the genetic predisposition of vulnerable groups. In the management of suicidal behaviour, a system of therapeutic re-culturation is needed with an emphasis on relevant culture- based therapies.

  9. SOCIAL ASPECTS OF COMPETITIVENESS

    2014-06-01

    Full Text Available One of the most important conditions of the existence of every organization, every enterprise is to insure the long-term sustainable development, one of the conditions of which is the increase of an organizational competitiveness. In modern economic conditions, social aspects of competitiveness are now in the foreground of interest, because just the strategy of social responsibility (SSR of modern enterprises can assure some commercial benefits, in responding, at the same time, to the social demands and in creating its well-being. Such an approach is in the basis of the notion of competitiveness. Along with «rigid parameters», such as price characteristics, the capability to deal with competitors, effective financial and production policies, «flexible factors» of competitiveness are of a big importance: a personnel potential, individual and collective competencies, organizational and managerial capabilities. As a result, we have formulated a research hypothesis: the organizational competitiveness is defined by individual and collective competencies of an organization, is based on socially responsible actions, confirms the demand for the object and insures its sustainable long-term development. Any organization should base all its actions aimed to increase its competitiveness on its intellectual potential, or on the management of individual and collective competencies that assure the sustainable development and the goal achievement. For every organizational strategic action, an effective combination of these competencies exists. So, we suggest a new definition of competitiveness: it is a social and economic category of understanding of the social responsibility, having as a central element individual and collective competencies, based on socially responsible actions of an enterprise, insuring its long-term sustainable development.

  10. INTERPERSONAL COMMUNICATION: PSYCHOLINGUISTIC ASPECT

    Directory of Open Access Journals (Sweden)

    Mitrofanova, I.I.

    2016-09-01

    Full Text Available The article considers language as the organization of the speech of any person in any situation, without which it is impossible to characterize the internal structure of the speech stream. Language is exactly a system of guidelines necessary for the activity in the social world. Communication is primarily nothing but as a way of making one or another correction in the image of the interlocutor’s world. In order for a language to serve as a means of communication, it must have a single or a similar understanding of reality behind it. Conversely, the unity of understanding the reality and the unity of coherence presuppose the possibility of adequate communication. A mandatory component of communication is the communicative act, that is, the act of sharing information between people. The speech, i.e. the natural sound language is an important means of conveying information that defines this aspect of the communication process as verbal communication. The idea of dialogue as the space, in which the exchange of information takes place, is defined as initial. Essentially, it is the dialogue that in this case acts as the backbone principle in dealing with problems of language. It is here that the essence of social and psychological transition to the analysis of communication is most visibly concentrated. An individual essentially "lives" in the world of Another person’s worlds, and studying the words of this person, he or she studies the "world" of Another person. Thus, the dialogue is not merely the interaction (verbal with another person, but, ultimately, the interaction with the world of culture.

    Although the psychological aspect of the rhinoplasty operation has been a subject of interest for a long time, with the exception of a few studies, sociological factors have been almost totally ignored. In this prospective study the personality characteristics and socioeconomic backgrounds of 216 rhinoplasty patients were evaluated. Between 1994 and 2000, a questionnaire and the Minnesota Multiphasic Personality Inventory (MMPI) were given preoperatively to 157 females and 59 males. The MMPI was also given to age-matched people as a control. Six months after surgery, patients were called on the telephone and asked to rate their satisfaction. According to questionnaire, a great majority of the rhinoplasty patients were young, unmarried women with high education levels. In the rhinoplasty group, one or more scales of the inventory were not in the normal ranges in 45% of the patients, whereas this proportion in the control group was 28% (p childish, highly active, impulsive, competitive, reactive, perfectionistic about themselves, talkative, and emotionally superficial. Male patients could be described as rigid, stubborn, over-sensitive, suspicious, perfectionistic, pessimistic, over-reactive, and having somatizations. Tension and anxiety with feelings of inferiority were found to be characteristics of the male patients. The satisfaction rate after six months was reported as 72%. There was no significant correlation between MMPI results and demographic variables, nor satisfaction rate. In conclusion, the rhinoplasty patients in our study are young people at the very beginning of their careers. It could be that their personalities and socioeconomic backgrounds combine to make aesthetic surgery rewarding enough, both socially and personally, to encourage them to follow through.

    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

The study was undertaken by means of an experimental design of blocks random that contemplate the following variables: intensity of the radiation source, (1850 MBq and 74 MBq); position of irradiation, (four positions); incidence of angle of the radiation (0, 15, 30, 45, 60 and 75 grades) and the absorbed dose in air, (0.005, 0.010, 0.020, 0.050 and 0.100 Gy). Then null hypothesis it was to suppose that there was not difference among the stockings of each treatment, to used the statistical of Duncan to carry out tests of stockings at a level of significance of 5%.These tests of stockings throw the following results in those variables of the experimental design: The irradiations carried out so much with the source pattern secondary of {sup 90}Sr/{sup 90}Y of 1850 MBq and of 74 MBq, they are equivalent reason why they can be used indistinctly. The responses of each one of the glasses of the card are strongly anisotropic for each glass; four positions of irradiation is used: glass 1 (window of 171 mg cm{sup -2} of Pb) it presents six populations in the angular response being from maximum to minimum: 15, 30, 0, 45, 60 and 75 grades. Glass 2 (free window) it presents four populations in the angular response being from maximum to minimum: 15, 30; 45, 0; 60 and 75 grades. - The Doses absorbed in air imparted to the dosimetros were the following ones: T1 = 0.005, T2 0.010, T3 = 0.020, T4 0.050 and - T5 = 0.10 Gy, being the responses of both glasses significantly for each treatment: glass 1 present four populations in the response to those treatments being from maximum to minimum: T5; T4; T3 and T2=T1, (that is to say to low dose the glass cannot differentiate them). Glass 2 present the same four populations in the response to the treatments. Finally it was determined the angular response for each glass in accordance with the ICRU 43 and using the coefficients of conversion, (of transmission and angular) of the norm IS0 6980 (1992), considering as the operative unit to H{sup (0.07;angular)}.

The technique used is that of comparison of stockings, (ANOVA; Variance Analysis, when samples of the same one were had size; and/or GLM, Widespread Lineal Models, when the samples were of different size), by means of the use of those Duncan statistics, SNK, Tukey, Gabriel; the results are validated proving the kindness of adjustment of the experimental data to a Normal distribution by means of the Shapiro-Wilks statistics.The experimental design used consists on a test of two vias: a via is the variable card with two levels, (crystal 1 and 2), the other via is the variable irradiation position with four levels, (LS=left superior, SR= right superior, LI= left Inferior, IR = right inferior). The irradiations carried out in blocks of four personal dosemeters in a gamma radiation beam range of Cobalt 60; carrying out three repetitions of the design. With object of proving the homogeneity of the filter of A1 in those personal dosemeters the experimental design was executed for those cards without personal dosemeters.They were also carried out tests of stockings to the readings of bottom and sensibility of the reader equipment, (Harshaw, model marks 2271), certain that doesn{sup t} exist differences for sequence of reading, but if in the stockings of the sensibility, (they were 4 different populations). The responses of the dosemeters were corrected subtracting him the reading correspondence of bottom and by sensibility of the reader equipment before subjecting them to the tests of stockings mentioned. Of the results of the tests of stockings for the cards with and without personal dosemeters, and for the bottom readings and sensibility of the reader equipment; and of the adjustment kindness to the normal for each game of data.The main conclusions that they were derived of this study they are: i.That the reader equipment presents differences statistically significant ({alpha}=5%) in their sensibilities; that which is necessary correct the readings of the dosemeter, making stand out the necessity of building the curves of operation of the equipment for the bottom and the sensibility. ii. The filter of A1 is not equivalent among the different personal dosemeters i i.For this sample of 40 cards with personal dosemeters to the one fewer exist: eleven populations different statistic significant, ({alpha}) to the response glass 1 five for the response of the glass 2, respectively. i v. That exist difference significant statistical, ({alpha} =5%) among the repetitions; what implies that it is necessary to control but strictly the experimental parameters to the one moment of carrying out the irradiations, (field size, correction for time of obturator of the source, distances source-detecting, etc), since the influence of the reader equipment it has already been considered.

  1. Verb aspect, alternations and quantification

    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.

    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

    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.

    Full Text Available The reproductive cycle of the eared horse mussel, Modiolus auriculatus, was followed for one year from February, 2011 to January, 2012 based on 240 individuals collected from Hurghada, north coast of Red Sea, Egypt. The gonadal maturation of M. auriculatus was examined by means of macroscopic and histological preparations of the mantle. Annual cycle with periods of growth, maturity and discharge of gonadic products occurs simultaneously in both sexes. Ripe individuals were observed throughout the year. The largest number of spawning for the individuals occurred from March to June and July for the population. So, it was clear to identify one heavy spawning period for this species. Sexation of M. auriculatus did not differ significantly from 1:1. Sexes were distinguishable in all individuals at the ripe stage with a shell length greater than 3.00 cm. A direct positive correlation was observed between gonad index and water temperature.

    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.

    With the development of the Internet and the WWW, information treatment has gained a new dimension. (Intelligent) software agents are one of the means expected to relieve human staff of the burden of information overload, and in the future to contribute to safeguards data acquisition, data evaluation and decision-making. An overview is given for the categories of Internet, intranet and desktop agents. Aspects of the potential application of agents are described in three fields: information access and delivery, collaboration and workflow management, adaptive interfaces and learning assistants. Routine application of agents is not yet in sight, but the scientific and technical progress seems to be encouraging. (author)

    Finally filling a gap in the literature for a text that also adopts the chemist's view of this hot topic, Professor Likhtenshtein, an experienced author and internationally renowned scientist, considers different physical and engineering aspects in solar energy conversion. From theory to real-life systems, he shows exactly which chemical reactions take place when converting light energy, providing an overview of the chemical perspective from fundamentals to molecular harvesting systems and solar cells. This essential guide will thus help researchers in academia and industry better understand solar energy conversion, and so ultimately help this promising, multibillion euro/dollar field to expand.

    2012-01-01

    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

    Cassidy, V R; Koroll, C J

    1994-10-01

    The requirements of leadership in the current environment of health care reform necessitate a clear distinction between leadership and management, an alteration in traditional leadership roles, and an evaluation of the knowledge and skills needed to address the ethical issues that arise from such reform. Transformational leadership is well suited to the current climate in health care because of the manner in which it actively embraces and encourages innovation and change. The article explores the elements of transformational leadership, describes the need for transformational leaders to be cognizant of the ethical aspects of their roles, and outlines the responsibilities of transformational leaders as moral agents.

    Harman, R.

    1979-01-01

    The main fundamental aspects and problems of cathodic sputtering used mainly for thin film deposition and sputter etching are discussed. Among many types of known sputtering techniques the radiofrequency /RF/ diode sputtering is the most universal one and is used for deposition of metals, alloys, metallic compounds, semiconductors and insulators. It seems that nowadays the largest number of working sputtering systems is of diode type. Sometimes also the dc or rf triode sputtering systems are used. The problems in these processes are practically equivalent and comparable with the problems in the diode method and therefore our discussion will be, in most cases applicable for both, the diode and triode methods

    Full Text Available SUMMARY This literature review analyzed the evidence on nutritional aspects related to the pathogenesis and progression of endometriosis. Diets deficient in nutrients result in changes in lipid metabolism, oxidative stress and promote epigenetic abnormalities, that may be involved in the genesis and progression of the disease. Foods rich in omega 3 with anti-inflammatory effects, supplementation with Nacetylcysteine, vitamin D and resveratrol, in addition to the increased consumption of fruits, vegetables (preferably organic and whole grains exert a protective effect, reducing the risk of development and possible regression of disease. Dietary re-education seems to be a promising tool in the prevention and treatment of endometriosis.

    Full Text Available The trusts have been frequently used in the countries which function under the Anglo-Saxon law system, but it most certainly represents an innovation in the new Romanian legislation. For this reason, in this paper, we tried to highlight the main differences between the trust regulated in the Romanian Civil code and its corespondent in other legal systems. Observing that the trust in an institution that is mainly theoretical, and the reluctance of practicioners in using it, we tried to analyze the trust, regarding its practical side. In this paper, we will take into consideration the following aspects: the rights that the trustee acquires after establishing the trust, that will be explained through the new regulations regarding the division of assets, the quality of the parties and the limits in which the trustee may be held liable. Other important aspects are: the means that the new regulations provide in order to protect the interests of the creditors and at the same time, the fiduciary assets; the formalities which the law requires and the means of termination of the contract. In the end, in order to identify alternative solutions, we will compare the trust (regulated in the Civil code with the management of assets that belong to a third party.

    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

    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.

    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.

    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)

  16. Neurological aspects of lead intoxication

    Energy Technology Data Exchange (ETDEWEB)

    Lehner, H

    1980-05-08

    This study gives a survey over the medical and scientific literature on lead intoxications, which were published until 1979. Neurologic aspects are of particular interest. At present dramatic cases of lead intoxications occur only rarely. However, there are numerous studies about cases of chronical, partly subclinical intoxications. This chronical type of lead intoxication can become manifest clinically as relatively vague symptoms, for example vertigos, insomnia, headaches and weakness. Contrary to this, serious encephalopathies, even with fatal outcome, and polyneuropathies with typical paresis of the radial nerve are preferably observed in acute lead intoxications. Besides the numerous sources of intoxication, also the different opinions found in literature are discussed, concerning the effects of lead on the human body. The fact that there are differing opinions about the limiting value of the blood-lead level at which intoxication symptoms have to be expected, becomes apparent when the determined blood-lead level values are compared and evaluated. Besides the description of general intoxication effects, the discussion of the neurologic aspects found in literature - not only those concerning the central, but also the peripheral system - are preferably concerned. Reports about neuropsychical alterations due to lead exposure, which are mainly found in children, supplement the numerous descriptions of the macroscopic and microscopic alterations of the nervous system provoked by lead. Finally the therapeutic and prophylactic measures given in the literature are discussed.

    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.

    2018-05-01

    Full Text Available Throughout the paper, we have highlighted some controversial aspects regarding the crime of tax evasion, referring to some important decisions of the High Court of Cassation and Justice and also of the Bucharest Court of Appeal. Debating upon the impunity provision stated by art. 10 of Law no. 241/2005, the study also sheds light upon the issue of the perspective of the judicial organs regarding the juridical regime of the tax due for dividends. The main focus of the paper leads to the situations when there is legal ground for the tax due for dividends to be considered part of the damage caused by tax evasion crime. The study includes a short analysis of some relevant provisions of the Romanian Fiscal Code and also some aspects deriving from decisions issued by the Administrative and Tax Litigation Chamber of The High Court of Cassation and Justice concerning the legal regime of dividends. Consequently, the authors are presenting both perspectives of the interpretation of the issue regarding the tax due for dividends to be considered part of the damage caused by tax evasion crime, resulting from two decisions of the two Criminal Sections of The Bucharest Court of Appeal, also arguing in favour of the most solid interpretation among them

    Full Text Available Cancer is accompanied by important psychological distress experienced by both patient and family. From the moment of the diagnosis on, the patient has to develop a great number of mechanisms and tasks of adjustment to the illness and its circumstances. The high prevalence of anxiety and depressive disorders during the course of cancer increases in the end stage disea‐ se. Therefore, a global plan of intervention integrating somatic and psychological/ psychiatric care throughout all the phases of the illness is crucial in the treatment of these patients. Health professionals working on this field can also experience emotional reactions to their patients’ suffering. They should be aware of the emotional aspects involved and develop training to help them intervene adequately with the patient and the family. The articulation between oncologists, palliative care professionals, and mental health care teams can be of great help in providing good quality of care to cancer patients.

    Full Text Available The slipper lobster, Scyllarides latus (Latreille, 1803, is the only representative species of the genusScyllarides in the Mediterranean Sea. In this study, we examined some biological aspects of this species sampled in the Straits of Messina. The specimens were sexed, measured and weighed. The relationships between body measurements (length and width of the carapace, antennal length and length-weight relationship were calculated. Furthermore, the correlation matrix (Pearson’s coefficient was calculated. Two hundred specimens were collected, ranging in size from 81 to 305 mm in total length, and between 21 and 1490 g in weight. A rare juvenile of 39 mm CL was recorded. A sex ratio of 1:1 was found. The carapace length – weight relationship was almost isometric. The wide size range sampled and the presence of a juvenile, indicate an interesting habitat for studying the presence and growth of Scyllarides latus in the Straits of Messina.

    The authors highlight a few medical, biological and psycological aspects of the use of nuclear weapons, drawing attention to their viewpoint that doctors should actively participate in the fight against nuclear armament. The short and long-term radiation effects on man and ecology are presented based on the Hiroshima and Nagasaki experiences. The danger of human error within this framework is emphasised and it is suggested that it is the medical profession's duty to point out how the effect of stress and boredom can lead to a nuclear catastrophe. Medical expertise may also help in the identification of unstable personalities among those who have access to nuclear weapons and in the understanding of the psycology of international conflicts and the psychopathology of those leaders who would use nuclear war as an instrument of national policy. Finally the effects of the nuclear war threat on children and teenagers are considered. (C.F.)

    Pawłowski, L.; Cel, W.; Wójcik Oliveira, K.

    2018-05-01

    Nowadays, world development depends on the energy supply. The use of fossil fuels leads to two threats: depletion of resources within a single century and climate changes caused by the emission of CO2 from fossil fuels combustion. Widespread application of renewable energy sources, in which biofuels play a major role, is proposed as a counter-measure. The paper made an attempt to evaluate to what extent biofuels meet the criteria of sustainable development. It was shown that excessive development of biofuels may threaten the sustainable development paradigms both in the aspect of: intergenerational equity, leading to an increase of food prices, as well as intergenerational equity, resulting in degradation of the environment. The paper presents the possibility of sustainable biofuels production increase.

    Objective: the present study is aimed at showing the different characteristics of pharyngoceles in imaging exams (video fluoroscopic swallowing exam [VFSE] and computed tomography) and its correlation with clinical presentation. Material and method: pharyngocele cases were selected in imaging exams (video fluoroscopic swallowing exam [VFSE] and computed tomography) realized in our service, realizing clinical presentation correlation. Results: pharyngocele presents frequently with small dimensions and narrow orifice. When the size enlarges, clinical presentation is more evident and diverse, which can confuse with other cervical lesions that enlarge with Valsalva maneuver. Differential diagnosis can be done by imaging evaluation. Conclusion: we intended to demonstrate that many times pharyngocele can be presented with different aspects, not always being easy to recognize by clinics or imaging exams, but its diagnosis must be always remembered in our daily practice.

  5. Immune Aspects of Female Infertility

    Directory of Open Access Journals (Sweden)

    Andrea Brazdova

    2016-05-01

    Full Text Available Immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. Semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. The immune rejection of male semen in the female reproductive tract is explained as the failure of natural tolerance leading to local and/or systemic immune response. Present active immune mechanism may induce high levels of anti-seminal/sperm antibodies. It has already been proven that iso-immunization is associated with infertility. Comprehensive studies with regards to the identification of antibody-targets and the determination of specific antibody class contribute to the development of effective immuno-therapy and, on the other hand, potential immuno-contraception, and then of course to complex patient diagnosis. This review summarizes the aspects of female immune infertility.

  6. Holistic aspects of quantum mechanics

    International Nuclear Information System (INIS)

    Pietschmann, H.

    1987-01-01

    Aspects of quantum mechanics irreconcilable with classical physics are outlined. Quantum mechanics started with a negative statement about reality, namely: it is impossible to determine momentum and position of a particle simultaneously. Meanwhile it has generated an impressive body of predictions which can be tested and have been confirmed by suitable experiments. As a consequence a naive, local, materialistic concept of reality must be abolished and a novel approach, the holistic is introduced. This is illustrated by some examples e.g. the Pauli exclusion principle for electrons, the electron capture decay of 135 La as a model of the wavefunction reduction, the Bohr radius of the atom, electron localisation in the atom. An example from the quantum field theory is the calculation of magnetic moments of electron and muon where a particle cannot be considered separately and all other particles must be taken into account.

    Science.gov (United States)

    Nigg, B M; Yeadon, M R

    1987-01-01

    The purpose of this paper is to discuss some biomechanical aspects of playing surfaces with special focus on (a) surface induced injuries, (b) methodologies used to assess surfaces and (c) findings from various sports. The paper concentrates primarily on questions related to load on the athlete's body. Data from epidemiological studies suggest strongly that the surface is an important factor in the aetiology of injuries. Injury frequencies are reported to be significantly different for different surfaces in several sports. The methodologies used to assess surfaces with respect to load or performance include material tests and tests using experimental subjects. There is only little correlation between the results of these two approaches. Material tests used in many standardized test procedures are not validated which suggests that one should exercise restraint in the interpretation of these results. Point elastic surfaces are widely studied while area elastic surfaces have received little attention to date. Questions of energy losses on sport surfaces have rarely been studied scientifically.

    1978-01-01

    An appraisal of the current situation concerning some of the theoretical aspects of solid surfaces is presented. First of all the characterization of the surfaces that involves the surface geometry and atomic composition for both the clean and adsorbed surfaces is discussed. Under this, the methods for determining the surface structure (such as low energy electron diffraction, field electron and field ion microscopy, photo emission spectroscopy and atomic scattering) and methods for determining the surface composition by the Auger electron spectroscopy are outlined. In the second part, emphasis is on the electronic structure of the clean and adsorbed surfaces. The measurements of ultra-violet and X-ray photo electron spectra are shown to yield the information about the surface electronic structure. In this context the many body effects such as, shake-up and relaxation energy etc. are discussed. Finally the status of the theory in relation to the experiments on angular resolved and polarization dependent photo emission are presented. (auth.)

The following topics are discussed: technical reasons for reprocessing; economic reasons for reprocessing; past experience; justification for advanced reprocessing R and D; technical aspects of current reprocessing development. The present developments are mainly directed at the reprocessing of breeder reactor fuels but there are also many applications to light-water reactor fuel reprocessing. These new developments involve totally remote operation, and maintenance. To demonstrate this advanced reprocessing concept, pilot-scale demonstration facilities are planned with commercial application occurring sometime after the year 2000

    The paper presents the aspects of international GHG (greenhouse gases) emission trading, such as: quality of GHG emission data, possible partners, monitoring activity, market mechanisms and difficulties. The following conclusions are drown: - debates on international trade with GHG emissions are currently in a very early stage; - actions are possible and feasible, particularly after Kyoto Conference, as versatile mechanism (besides the Joint Implementation Projects) which have in view the lowering of the global emission costs in different zones of the planet; - difficulties concerning monitoring, reporting and verification, practically preclude implementing a system of emission trading covering all the GHG, all the sources and reservoirs; - an international viable system of emission trading could initiate with a limited number of participants and consideration of only emission categories easy to be confined and surveyed; - existence of a national market and corresponding institutions for monitoring which could booster an international system development

    2013-01-01

    Full Text Available We raise several elementary questions pertaining to various aspects of means. These questions refer to both known and newly introduced families of means, and include questions of characterizations of certain families, relations among certain families, comparability among the members of certain families, and concordance of certain sequences of means. They also include questions about internality tests for certain mean-looking functions and about certain triangle centers viewed as means of the vertices. The questions are accessible to people with no background in means, and it is also expected that these people can seriously investigate, and contribute to the solutions of, these problems. The solutions are expected to require no more than simple tools from analysis, algebra, functional equations, and geometry.

    1981-01-01

    The legal basis for the use of nuclear energy is generally given by an Atomic Energy Act. Additionally, however, a system of regulations and standards has to be set up to lay down more detailed requirements. The fundamental philosophy and strategy has to be specified by governmental organizations. For the specification and implementation of the requirements some minimum organizational arrangements are necessary, which are not only restricted to governmental organizations. Furthermore procedural regulations have to be laid down before the implementation phase. This includes aspects like public participation in the licensing procedure. In practice, however, the implementation of the legal requirements always shows some weakness of the basic legal requirements. To learn from this experience some examples are presented, which gave rise to difficulties in the implementation procedure. (orig./RW)

  17. Cognitive aspect of diagnostic errors.

    Diagnostic errors can result in tangible harm to patients. Despite our advances in medicine, the mental processes required to make a diagnosis exhibits shortcomings, causing diagnostic errors. Cognitive factors are found to be an important cause of diagnostic errors. With new understanding from psychology and social sciences, clinical medicine is now beginning to appreciate that our clinical reasoning can take the form of analytical reasoning or heuristics. Different factors like cognitive biases and affective influences can also impel unwary clinicians to make diagnostic errors. Various strategies have been proposed to reduce the effect of cognitive biases and affective influences when clinicians make diagnoses; however evidence for the efficacy of these methods is still sparse. This paper aims to introduce the reader to the cognitive aspect of diagnostic errors, in the hope that clinicians can use this knowledge to improve diagnostic accuracy and patient outcomes.

  18. Geological aspects of acid deposition

    Bricker, O.P.

    1984-01-01

    The general pattern of rain falling on the earth and reacting with the materials of the lithosphere (the weathering reactions so familiar to every beginning geology student) began soon after the earth was formed and has continued to the present. Anthropogenic additions to the natural acidic components of the atmosphere have increased since the time of the industrial revolution until they now rival or exceed those of the natural system. The severity of the environmental perturbations caused by these anthropogenic additions to the atmosphere has become a hotly debated topic in scientific forums and in the political arena. The six chapters in this book address various aspects of the acid deposition phenomenon from a geological perspective. It is hoped that the geological approach will be useful in bringing the problem more clearly into focus and may shed light on the geochemical processes that modify the chemical composition of acid deposition after it encounters and reacts with the materials of the lithosphere

    2010-11-01

    To review recent literature around the controversial diagnosis of personality disorder, and to assess the ethical aspects of its status as a medical disorder. The diagnostic currency of personality disorder as a psychiatric/medical disorder has a longstanding history of ethical and social challenges through critiques of the medicalization of deviance. More recently controversies by reflexive physicians around the inclusion of the category in the forthcoming revisions of International Classification of Diseases and Diagnostic and Statistical Manual of Mental Disorders classifications reflect the problems of value-laden criteria, with the diagnostic category being severely challenged from within psychiatry as well as from without. The clinical diagnostic criteria for extremely value-laden psychiatric conditions such as personality disorder need to be analyzed through the lens of values-based medicine, as well as through clinical evidence, as the propensity for political and sociolegal appropriation of the categories can render their clinical and diagnostic value meaningless.

    1975-01-01

    A scintillation counter, particularly for counting gamma ray photons, includes a massive lead radiation shield surrounding a sample-receiving zone. The shield is disassembleable into a plurality of segments to allow facile installation and removal of a photomultiplier tube assembly, the segments being so constructed as to prevent straight-line access of external radiation through the shield into radiation-responsive areas. Provisions are made for accurately aligning the photomultiplier tube with respect to one or more sample-transmitting bores extending through the shield to the sample receiving zone. A sample elevator, used in transporting samples into the zone, is designed to provide a maximum gamma-receiving aspect to maximize the gamma detecting efficiency. (U.S.)

  2. Health aspects of automotive pollutants

    Energy Technology Data Exchange (ETDEWEB)

    Jouan, M

    1973-01-01

    General health aspects of carbon monoxide, lead, nitrogen oxides, unburned hydrocarbons, and aldehydes are described. Unlike spark ignition engines, diesel engines emit but minimal quantities of carbon monoxide. Automotive carbon monoxide may cause chronic poisoning by its combination with hemoglobin. The threshold value beyond which physiological changes occur lies at 2.5 percent carboxyhemoglobin. Nitric oxide, and especially nitrogen dioxide cause pulmonary edema, impaired respiratory function, and chronic bronchitis in very low concentrations. According to regulations implemented in France, a CO concentration of 40 ppM/hr must occur not more than 1 percent of the time on a yearly basis. A level of 15 ppm must not be exceeded for more than 15 percent of the time in any 9-hour period. The maximum allowable 1-hour nitrogen oxide concentration is set at 0.25 ppM. The emission standards implemented, as well as favorable meteorological conditions have resulted in an abatement of the CO concentrations in Paris.

    2007-11-01

    Due to increasing immigration in Germany the German Mental Health Care System today has to deal in a growing number with the assessment of the level of psychic functioning and the capability of self control in patients of different ethnic origin. For clinicians this is a challenge, since suicidal behaviour in terms of its frequency, meaning, motives and manner is very much dependent on the cultural context in which it occurs. Moreover, the general attitude of an individual towards suicide is embedded in the culture of origin of the immigrant. Until now there has been only little systematic research on the influence of culture on suicidal behaviour. In this review the traditions of suicidal behaviour in different cultures in their religious and historical dimensions will be reflected. The historical and cultural roots of suicidal behaviour will be put in context to a categorization of the different variants of suicide, such as institutionalized suicide versus individualized suicide. Psychodynamic aspects of suicidal ideation will be highlighted in cross-cultural perspective with a distinction between a. the wish to die, b. the wish to kill and c. the wish to be killed. It will be shown that there can be differentiated between accepted and non-accepted suicide. With respect to epidemiology there will be discussed the impact of culture on the suicide rates across cultures. The influence of culture on the psychopathology of suicidal behaviour will be summed up systematically. These aspects are of high relevance for the understanding and assessment of suicidal crisis in immigrants, since the suicidal patient even today - although subconsciously - is influenced by the deep rooted traditions of suicidal behaviour in his culture of origin.

  4. Psychosomatic aspects of Cushing's syndrome.

    2010-06-01

    There has been growing interest in the psychosocial aspects of Cushing's syndrome, such as the role of life stress as a pathogenetic factor, the association with affective disorders, and the presence of residual symptoms after treatment. Interestingly, a temporal relationship between stressful life events and disease onset is relevant only to pituitary-dependent Cushing's disease, and not to the pituitary-independent forms. A number of psychiatric and psychological disturbances may be associated with the active hypercortisolemic state, regardless of its etiology. Within the high frequency of mood disorders (about 60%), major depression is the most common complication. Other psychopathological aspects include mania, anxiety disorders, psychological symptoms (demoralization, irritable mood, somatization) and cognitive impairment. Cognitive symptoms are associated with brain abnormalities (mainly loss of brain volume). Quality of life may be seriously compromised during both active and post-treatment phases. Long-standing hypercortisolism may imply a degree of irreversibility of the pathological process. Recovery, thus, may be delayed and be influenced by highly individualized affective responses. Outcomes of Cushing's syndrome treatment are not fully satisfactory. Within its great complexity, a conceptual shift from a merely biomedical care to a psychosomatic consideration of the person and his/her quality of life appears to be necessary to improve effectiveness. It is time to translate the research evidence that has accumulated into clinical practice initiatives. To patients who show persistence or even worsening of psychological distress upon adequate endocrine treatment psychiatric/psychological interventions should be readily available. Applying interdisciplinary expertise and addressing the needs for rehabilitation would markedly improve final outcome.

    In this paper there are showed and debated some situation in which psychological effects like loss aversion, reference point, status-quo and framming effects can influence the deccision of the consumer and are not consistent with the standard economic model.In addition to this aspects, Cumulative Prspect Theory enhance the fact that decision makers overestimate low peobabilities and underestimate high probabilities,thus buying inadequate insurance in many situation.in thiss sense, in order to support this idea I tried to make a qualitative presentation of the model used on the insurance market using Prelec function which is the function related with the Cumulative Prospect Theory which can be used in the insurance context.The weak points of the theory of expected utility are explained through this new perspectives and nevertheless aspects like insensivity to bad news concerning incomes,elasticity of price,displacements of status-quo and default,disposition effect and equity premium are taken into consideration.As example,I chose a Kunreuther experiment about insurance decision in with is underlyined the fact that for moderate risk people buy insurance with premiums that exceed the expected loss.There are demands for low deductibles in the the markets for extended guarantees and insurances for mobile phones where was observed that the insurance underwriting rate increases with the probability of loss keeping the expected loss constant.It is better to mention that the theory and the model that are presented here comes as complementary to the economic standard theory not as a substitute.

We find this constraint to be in agreement with long-established crystallographic studies of DNA.......Two separate regimes exist for the aspect ratio of DNA. A low aspect regime where DNA will twist further under strain and a high aspect regime where DNA will untwist under strain. The question of the overall geometry, i.e. the aspect ratio, of DNA is revisited from the perspective of a geometrical...

  8. Computational aspects of premixing modelling

    Fletcher, D.F. [Sydney Univ., NSW (Australia). Dept. of Chemical Engineering; Witt, P.J.

    1998-01-01

    In the steam explosion research field there is currently considerable effort being devoted to the modelling of premixing. Practically all models are based on the multiphase flow equations which treat the mixture as an interpenetrating continuum. Solution of these equations is non-trivial and a wide range of solution procedures are in use. This paper addresses some numerical aspects of this problem. In particular, we examine the effect of the differencing scheme for the convective terms and show that use of hybrid differencing can cause qualitatively wrong solutions in some situations. Calculations are performed for the Oxford tests, the BNL tests, a MAGICO test and to investigate various sensitivities of the solution. In addition, we show that use of a staggered grid can result in a significant error which leads to poor predictions of `melt` front motion. A correction is given which leads to excellent convergence to the analytic solution. Finally, we discuss the issues facing premixing model developers and highlight the fact that model validation is hampered more by the complexity of the process than by numerical issues. (author)

  9. Global aspects of gauge anomalies

    Zhang, H.

    1988-01-01

    This dissertation discusses the global aspects of gauge anomalies in even dimensions. After a very brief description of local gauge anomalies, the possible global gauge anomalies for various gauge theories are discussed using homotopy theory. One of the main results obtained in a general formula for the SU(n - k) global gauge anomaly coefficient in arbitrary 2n dimensions. The result is expressed in terms of the James number of the Stiefel manifold SU(n + 1)/SU(n - k) and the generalized Dynkin indices. From this, the possibilities of SU(n), SU(n - 1), and SU(2) global gauge anomalies in arbitrary 2n dimensions have been determined. We have also determined the possibilities of global gauge anomalies for the gauge groups SP(2N) and SO(N) in certain general dimensions, as well as for the exceptional gauge groups in specific dimensions. Moreover, several general propositions are formulated and proved which are very useful in the study of global gauge anomalies

  10. Environmental aspects of nuclear power

    Ward, D.P.

    1987-01-01

    Nuclear power provides the world with an important option for generating electricity. To successfully and safely utilize this power, engineering and environmental factors should be carefully considered throughout a nuclear power plant project, especially during the planning stages. This paper discusses the major environmental aspects of a nuclear power plant project from site selection to retirement. During the site selection process, both engineering and environmental resources must be identified and evaluated. Environmental resources include areas that support agricultural or aquatic commercial activities, habitats for commercial or endangered species, population centers, transportation systems, and recreational areas. Also, during the site selection process, the potential impacts of both construction and operating activities must be considered. In addition to the area actually disturbed by construction, construction activities also affect local services, such as transportation systems, housing, school systems, and other social services. Since nuclear power plants use a 'clean fuel,' generally the most significant operating activity having a potential environmental impact is the discharge of cooling water. The potential effect of this discharge on commercial activities and sensitive habitats should be thoroughly evaluated. Lastly, the method of decommissioning can affect long-range land use planning and should therefore be considered during the planning process. With appropriate planning, nuclear power plants can be constructed and operated with minimum environmental impact. (author)

    Ho, P.M.

    1996-01-01

    Various geometrical aspects of quantum spaces are presented showing the possibility of building physics on quantum spaces. In the first chapter the authors give the motivations for studying noncommutative geometry and also review the definition of a Hopf algebra and some general features of the differential geometry on quantum groups and quantum planes. In Chapter 2 and Chapter 3 the noncommutative version of differential calculus, integration and complex structure are established for the quantum sphere S 1 2 and the quantum complex projective space CP q (N), on which there are quantum group symmetries that are represented nonlinearly, and are respected by all the aforementioned structures. The braiding of S q 2 and CP q (N) is also described. In Chapter 4 the quantum projective geometry over the quantum projective space CP q (N) is developed. Collinearity conditions, coplanarity conditions, intersections and anharmonic ratios is described. In Chapter 5 an algebraic formulation of Reimannian geometry on quantum spaces is presented where Riemannian metric, distance, Laplacian, connection, and curvature have their quantum counterparts. This attempt is also extended to complex manifolds. Examples include the quantum sphere, the complex quantum projective space and the two-sheeted space. The quantum group of general coordinate transformations on some quantum spaces is also given

  13. Molecular radiation biology: Future aspects

    International Nuclear Information System (INIS)

    Hagen, U.

    1990-01-01

    Future aspects of molecular radiation biology may be envisaged by looking for unsolved problems and ways to analyse them. Considering the endpoints of cellular radiation effects as cell inactivation, chromosome aberrations, mutation and transformation, the type of DNA damage in the irradiated cell and the mechanisms of DNA repair as excision repair, recombination repair and mutagenic repair are essential topics. At present, great efforts are made to identify, to clone and to sequence genes involved in the control of repair of DNA damage and to study their regulation. There are close relationships between DNA repair genes isolated from various organisms, which promises fast progress for the molecular analysis of repair processes in mammalian cells. More knowledge is necessary regarding the function of the gene products, i.e. enzymes and proteins involved in DNA repair. Effort should be made to analyse the enzymatic reactions, leading to an altered nucleotide sequence, encountered as a point mutation. Mislead mismatch repair and modulation of DNA polymerase might be possible mechanisms. (orig.)

    1989-11-01

    Data available in the literature on the nutritional aspects of irradiated shrimp are reviewed and the indication is that irradiation of shrimp at doses up to about 3.2 kGy does not significantly affect the levels of its protein, fat, carbohydrate and ash. There are no reports on the effect of irradiation of shrimp above 3.2 kGy on these components. Limited information available indicates that there are some minor changes in the fatty acid composition of shrimp as a result of irradiation. Irradiation also causes some changes in the amino acid composition of shrimp; similar changes occur due to canning and hot-air drying. Some of the vitamins in shrimp, such as thiamine, are lost as a result of irradiation but the loss is less extensive than in thermally processed shrimp. Protein quality of shrimp, based on the growth of rats as well as that of Tetrahymena pyriformis, is not affected by irradiation. No adverse effects attributed to irradiation were found either in short-term or long-term animal feeding tests

    The scientific community is very interested in the biological aspects of gender disorders and sexual orientation. There are different levels to define an individual's sex: chromosomal, gonadic, and phenotypic sex. Concerning the psychological sex, men and women are different by virtue of their own gender identity, which means they recognize themselves as belonging to a determinate sex. They are different also as a result of their own role identity, a set of behaviors, tendencies, and cognitive and emotional attitudes, commonly defined as "male" and "female". Transsexuality is a disorder characterized by the development of a gender identity opposed to phenotypic sex, whereas homosexuality is not a disturbance of gender identity but only of sexual attraction, expressing sexual orientation towards people of the same sex. We started from a critical review of literature on genetic and hormonal mechanisms involved in sexual differentiation. We re-examined the neuro-anatomic and functional differences between men and women, with special reference to their role in psychosexual differentiation and to their possible implication in the genesis of homosexuality and identity gender disorders. Homosexuality and transsexuality are conditions without a well defined etiology. Although the influence of educational and environmental factors in humans is undeniable, it seems that organic neurohormonal prenatal and postnatal factors might contribute in a determinant way in the development of these two conditions. This "organicistic neurohormal theory" might find support in the study of particular situations in which the human fetus is exposed to an abnormal hormonal environment in utero.

    Compact stellarators could combine the good confinement and high beta of a tokamak with the inherently steady state, disruption-free characteristics of a stellarator. Two U.S. compact stellarator facilities are now in the conceptual design phase: the National Compact Stellarator Experiment (NCSX) and the Quasi- Poloidal Stellarator (QPS). NCSX has a major radius of 1.4 m and a toroidal field up to 2 T. The primary feature of both NCSX and QPS is the set of modular coils that provide the basic magnetic configuration. These coils represent a major engineering challenge due to the complex shape, precise geometric accuracy, and high current density of the windings. The winding geometry is too complex for conventional hollow copper conductor construction. Instead, the modular coils will be wound with flexible, multi strand cable conductor that has been compacted to a 75% copper packing fraction. Inside the NCSX coil set and surrounding the plasma is a highly contoured vacuum vessel. The vessel consists of three identical, 120 deg. segments that are bolted together at double sealed joints. The QPS device has a major radius of 0.9 m, a toroidal field of 1 T, and an aspect ratio of only 2.7. Instead of an internal vacuum vessel, the QPS modular coils will operate in an external vacuum tank. (author)

    2014-01-01

    Peacekeeping operations are but one aspect of the systems of peace that have evolved over the past seven decades in a world that is riven with violence of all kinds. With the end of cold war in the late eighties of the last century we have come to see much intrastate violence, in addition to usual interstate hostilities and war, arising out of religious, political, ethnic and economic differences between people. In the changed scenario peacekeeping operations have become complex politico-military-humanitarian efforts. A soldier, trained for conventional military operations, is obliged to participate in the unconventional operations of waging peace in alien lands often in volatile and violent situations and in the process he stands to get exposed to widely variable demands for adjustment that have the potential to bring to the fore many maladaptive responses. Peacekeeping operations also have the potential to offer opportunities for growth and resilience. India is a major player in peacekeeping activities for well over sixty years all over the world. It is necessary for the commanders and mental health professionals to understand the multifarious factors that impinge on the peacekeeping soldier's mind and the emerging patterns of responses thereof for effective management trained manpower and fulfillment of mission objectives.

    2014-01-01

    This review is focused on the general mechanisms of metal toxicity in humans. The possible and mainly confirmed mechanisms of their action are discussed. The metals are divided into four groups due to their toxic effects. First group comprises of metal ions acting as Fenton reaction catalyst mainly iron and copper. These types of metal ions participate in generation of the reactive oxygen species. Metals such as nickel, cadmium and chromium are considered as carcinogenic agents. Aluminum, lead and tin are involved in neurotoxicity. The representative of the last group is mercury, which may be considered as a generally toxic metal. Fenton reaction is a naturally occurring process producing most active oxygen species, hydroxyl radical: Fe(2+) + He2O2 ↔ Fe(3+) + OH(-) + OH(•) It is able to oxidize most of the biomolecules including DNA, proteins, lipids etc. The effect of toxicity depends on the damage of molecules i.e. production site of the hydroxyl radical. Chromium toxicity depends critically on its oxidation state. The most hazardous seems to be Cr(6+) (chromates) which are one of the strongest inorganic carcinogenic agents. Cr(6+) species act also as oxidative agents damaging among other nucleic acids. Redox inactive Al(3+), Cd(2+) or Hg(2+) may interfere with biology of other metal ions e.g. by occupying metal binding sites in biomolecules. All these aspects will be discussed in the review.

    Over the last three decades photodynamic therapy (PDT) has been developed to a useful clinical tool, a viable alternative in the treatment of cancer and other diseases. Several disciplines have contributed to this development: chemistry in the development of new photosensitizing agents, biology in the elucidation of cellular processes involved in PDT, pharmacology and physiology in identifying the mechanisms of distribution of photosensitizers in an organism, and, last but not least, physics in the development of better light sources, dosimetric concepts and construction of imaging devices, optical sensors and spectroscopic methods for determining sensitizer concentrations in different tissues. Physics and biophysics have also helped to focus on the role of pH for sensitizer accumulation, dose rate effects, oxygen depletion, temperature, and optical penetration of light of different wavelengths into various types of tissue. These are all important parameters for optimally effective PDT. The present review will give a brief, physically based, overview of PDT and then discuss some of the main biophysical aspects of this therapeutic modality.

Until recently biochemists and biophysicists were not accustomed to thinking of these processes from the side of a high number of complex biochemical events and an equally high number of physical changes at molecular and cellular levels at the same time. Both types of researchers were convinced that their findings are the most decisive, having higher importance than the findings of the other scientist population. Both casts were wrong. Life, even at cellular level, has a number of interacting physical and biochemical mechanisms, which finally build up the creation of an "excited" cell that will respond to particular signals from the outer or inner world. This book handles both aspects of the signalling events, and in some cases tries to unify our concepts and help understand the signals that govern the life and death of our cells. Not only the understanding, bu...

    Full Text Available Peacekeeping operations are but one aspect of the systems of peace that have evolved over the past seven decades in a world that is riven with violence of all kinds. With the end of cold war in the late eighties of the last century we have come to see much intrastate violence, in addition to usual interstate hostilities and war, arising out of religious, political, ethnic and economic differences between people. In the changed scenario peacekeeping operations have become complex politico-military-humanitarian efforts. A soldier, trained for conventional military operations, is obliged to participate in the unconventional operations of waging peace in alien lands often in volatile and violent situations and in the process he stands to get exposed to widely variable demands for adjustment that have the potential to bring to the fore many maladaptive responses. Peacekeeping operations also have the potential to offer opportunities for growth and resilience. India is a major player in peacekeeping activities for well over sixty years all over the world. It is necessary for the commanders and mental health professionals to understand the multifarious factors that impinge on the peacekeeping soldier′s mind and the emerging patterns of responses thereof for effective management trained manpower and fulfillment of mission objectives

    Full Text Available Multiple sclerosis is the most common inflammatory, chronic and degenerative condition of the central nervous system, and represents the first cause of disability in young adults. In Mexico, 11 to 20 out of every 100 000 people suffer from this disease. The causes of multiple sclerosis remain unknown, but several theories have been proposed on its origin: the interaction of environmental factors, viral infectious factors and genetic and immune susceptibility of each individual patient, which induce an autoimmune response and promote neuronal/axonal degeneration. In this review, the immune reaction main components and neurodegeneration present in multiple sclerosis are analyzed, as well as the inflammatory cascade associated with demyelination. Available treatments’ main purpose is to modulate aspects related to the adaptive immune response (B and T cells. The therapeutic challenge will be antigen-specific immune-tolerance induction, for example, with the use of tolerance protocols with peptides or DNA or nanoparticles vaccines. Future therapies should aim to control innate components (microglia, macrophages, astrocytes and to promote remyelination. To optimize the treatment, a combined therapeutic approach targeting the control of inflammatory and neurodegenerative components of the disease and monitoring of biomarkers will be necessary.

    The theoretical aspects of thermonuclear fusion induced by laser are discussed. After outlining the basic features and the energetics of laser fusion in the chapter 1, various non-linear mechanisms responsible for an enhanced absorption of laser energy into the plasma and the stimulated scattering processes which hinder the absorption are discussed in the second chapter on laser plasma interactions. The third chapter on gas dynamics and the shock phenomena presents the mathematical formulation of the compression to high densities of the core of the pellet for its implosion. A hydrodynamic model developed to stimulate the evolution of laser heated symmetric plasma is outlined in the chapter four on numerichigly relativistic noninteracting particles, regular bouncing states may occur at high densities, or at high temperatures. The latter case is considered in details for the collapse phase of a hot universe; lepton pair creation may completely decelerate the collapse of a hot hadronic plasma, provided the observational parameters, the Hubble constant Hsub(deg), the matter parameter Ωsub(deg) and the deceleration parameter qsub(deg) satisfy certain constraint conditions

    2015-01-01

    Differential Geometry is a wide field. We have chosen to concentrate upon certain aspects that are appropriate for an introduction to the subject; we have not attempted an encyclopedic treatment. Book II deals with more advanced material than Book I and is aimed at the graduate level. Chapter 4 deals with additional topics in Riemannian geometry. Properties of real analytic curves given by a single ODE and of surfaces given by a pair of ODEs are studied, and the volume of geodesic balls is treated. An introduction to both holomorphic and Kähler geometry is given. In Chapter 5, the basic properties of de Rham cohomology are discussed, the Hodge Decomposition Theorem, Poincaré duality, and the Künneth formula are proved, and a brief introduction to the theory of characteristic classes is given. In Chapter 6, Lie groups and Lie algebras are dealt with. The exponential map, the classical groups, and geodesics in the context of a bi-invariant metric are discussed. The de Rham cohomology of compact Lie groups an...

    We investigate cosmological aspects of spontaneous baryogenesis driven by a scalar field, and present general constraints that are independent of the particle physics model. The relevant constraints are obtained by studying the backreaction of the produced baryons on the scalar field, the cosmological expansion history after baryogenesis, and the baryon isocurvature perturbations. We show that cosmological considerations alone provide powerful constraints, especially for the minimal scenario with a quadratic scalar potential. Intriguingly, we find that for a given inflation scale, the other parameters including the reheat temperature, decoupling temperature of the baryon violating interactions, and the mass and decay constant of the scalar are restricted to lie within ranges of at most a few orders of magnitude. We also discuss possible extensions to the minimal setup, and propose two ideas for evading constraints on isocurvature perturbations: one is to suppress the baryon isocurvature with nonquadratic scalar potentials, another is to compensate the baryon isocurvature with cold dark matter isocurvature by making the scalar survive until the present.

    For more than 10 years integrated care has been an inherent part of the German healthcare system. The aims of selective contracts are to minimize interface problems between outpatient and inpatient sectors, generalist und specialist care as well as to intensify competition. Despite repeated efforts by the legislator, comprehensive integrated healthcare is still limited to a few flagship projects. This is mainly due to low incentives on the part of both suppliers and customers. Therefore, this article focuses on the economic aspects of integrated care. From a theoretical perspective, integrated care improves efficiency in the healthcare sector by reducing interface problems and asymmetric information as well as by intensifying competition. In practice, however, there are a number of obstacles to implementation. Particularly noteworthy are the financial difficulties in addition to problems regarding sectoral budgeting and the long-term nature of investments. However, the political environment and thus the financial arrangements within the statutory health insurance seem to be more important for further development of integrated care in Germany than the financing issues.

  10. Psychopathy: Legal and neuroscientific aspects

    Full Text Available Psychopathy is characterised by emotional disturbances that affect interpersonal behaviour and decision-making. The objective of this paper is to review the most recent contributions to the field of neuroscience of psychopathy and the implications that this disorder has on the criminal legal field. In regards to this last aspect, we evaluate the issue of psychopaths’ accountability and the incidence of psychopathy in many other penal institutions. In terms of the contributions of neuroscience, we will focus on the orbitofrontal (ofPFC and ventromedial (vmPFC regions of the frontal lobes and on the amygdala. Data spanning from the nineteenth century to the present indicate that damage to the ofPFC and vmPFC is the basis of behaviours that have been referred to as pseudopsychopathic. The earlier during brain development the damage occurs, the more likely these behaviours will resemble those of psychopaths. The damage to the amygdala is rather related to impairments in the ability to distinguish facial expressions of fear and the capacity to feel emotions. Damage to ofPFC, vmPFC, and amygdala are highly relevant to the expression of pseudopsychopathic behaviours.

    US anti-abortion groups have used misinformation on the long-term psychological impact of induced abortion to advance their position. This article reviews the available research evidence on the definition, history, cultural context, and emotional and psychiatric sequelae of induced abortion. Notable has been a confusion of normative, transient reactions to unintended pregnancy and abortion (e.g., guilt, depression, anxiety) with serious mental disorders. Studies of the psychiatric aspects of abortion have been limited by methodological problems such as the impossibility of randomly assigning women to study and control groups, resistance to follow-up, and confounding variables. Among the factors that may impact on an unintended pregnancy and the decision to abort are ongoing or past psychiatric illness, poverty, social chaos, youth and immaturity, abandonment issues, ongoing domestic responsibilities, rape and incest, domestic violence, religion, and contraceptive failure. Among the risk factors for postabortion psychosocial difficulties are previous or concurrent psychiatric illness, coercion to abort, genetic or medical indications, lack of social supports, ambivalence, and increasing length of gestation. Overall, the literature indicates that serious psychiatric illness is at least 8 times more common among postpartum than among postabortion women. Abortion center staff should acknowledge that the termination of a pregnancy may be experienced as a loss even when it is a voluntary choice. Referrals should be offered to women who show great emotional distress, have had several previous abortions, or request psychiatric consultation.

  12. Environmental aspects of nuclear power

    Ward, D.P.

    1988-01-01

    Nuclear power provides the world with an important option for generating electricity. To successfully and safely utilize this power, engineering and environmental factors should be carefully considered throughout a nuclear power plant project, especially during the planning stages. This paper discusses the major environmental aspects of a nuclear power plant project from site selection to retirement. During the site selection process, both engineering and environmental resources must be identified and evaluated. Environmental resources include areas that support agricultural or aquatic commercial activities, habitats for commercial or endangered species, population centers, transportation systems, and recreational areas. Also during the site selection process, the potential impacts of both construction and operating activities must be considered. In addition to the area actually disturbed by construction, construction activities also affect local services, such as transportation systems, housing, school systems, and other social services. Since nuclear power plants use a ''clean fuel,'' generally the most significant operating activity having a potential environmental impact is the discharge of cooling water. The potential effect of this discharge on commercial activities and sensitive habitats should be thoroughly evaluated. Lastly, the method of decommissioning can affect long-range land use planning and should therefore be considered during the planning process

    1989-09-01

    The accident at Chernobyl revealed that there were shortcomings and gaps in the existing international mechanisms and brought home to governments the need for stronger measures to provide better protection against the risks of severe accidents. The main thrust of international co-operation with regard to nuclear safety issues is aimed at achieving a uniformly high level of safety in nuclear power plants through continuous exchanges of research findings and feedback from reactor operating experience. The second type of problem posed in the event of an accident resulting in radioactive contamination of several countries relates to the obligation to notify details of the circumstances and nature of the accident speedily so that the countries affected can take appropriate protective measures and, if necessary, organize mutual assistance. Giving the public accurate information is also an important aspect of managing an emergency situation arising from a severe accident. Finally, the confusion resulting from the unwarranted variety of protective measures implemented after the Chernobyl accident has highlighted the need for international harmonization of the principles and scientific criteria applicable to the protection of the public in the event of an accident and for a more consistent approach to emergency plans. The international conventions on third party liability in the nuclear energy sector (Paris/Brussels Conventions and the Vienna Convention) provide for compensation for damage caused by nuclear accidents in accordance with the rules and jurisdiction that they lay down. These provisions impose obligations on the operator responsible for an accident, and the State where the nuclear facility is located, towards the victims of damage caused in another country

    Mango is an important and very popular tropical fruit. Because of its short shelf life, however, its use is restricted to the areas of production. Since mango is a climacteric fruit, it is possible to extend its shelf life by delaying the ripening process and senescence by irradiation. The ripening process is very complex: it appears that the radiation-induced delay in ripening may be mediated through the inhibition of the enzyme(s) involved in ethylene production. The dose required for shelf-life extension is ≤1.5 kGy. Higher doses can lead to scalding, flesh darkening and development of hollow pockets. This review focuses on the chemical aspects of radiation-induced shelf-life extension of mangoes. At the low irradiation doses required for this shelf-life extension (≤1.5 kGy), the chemical effects are negligible. Irradiation does not affect the carotenoid levels, and has only a minor effect on the vitamin C level in a few mango varieties. No significant differences in the free and total (hydrolyzed) amino acids, or the protein content of Kent mangoes, have been detected between irradiated and unirradiated samples. During ripening of the mangoes the reducing sugar and the total sugar levels increase, but in the majority of the mango varieties these levels remain very similar in irradiated and unirradiated samples. There are some differences in the volatile compounds between irradiated and unirradiated Kent mangoes; however, these differences have no apparent effect on the taste and flavor of the irradiated mangoes

    One of the modern economy models is circular economy in which wastes should be considered as resource and used in an efficient and sustainable way. This also concerns to metals included in scraps. However, the need for metal recovery from waste is not only the result of the latest economic trends but also the result of large and constantly changing demand for metals. Shrinking natural sources of metals, concentrations of ores in small number of countries in the world and resulting from this dependence on import, geopolitical situation, new technologies demands are only a few most important determinants that have been changing the structure of the metal market over years. In this chapter, authors focused on the presentation of economic aspects of metal recovery from various sources. The chapter presents the characteristic of metal market elements (supply, demand and price) and changes that took place over decades, underlining the structure of precious and highly desirable metal market elements. Balance between the demand and supply ensures price stability and rationalizes inflation. However, growing demand on many means that secure supply chains, such as recycling and material recovery, are essential to ensure continuity in the supply chain and guarantee unrestricted technological progress and innovation. The data included in this chapter presents also the concentration of different metals and group of metals in wastes pointing that recycling of waste can become one of the possibilities of acquiring missing and critical metals. Metal-laden wastes include a few groups: waste electrical and electronic equipments, catalysts of different application, introduced on chemical, petrochemical or automotive market, galvanic wastes and wastewaters. The profitability assessment of recycling processes is very complicated. Nevertheless cited data shows that profitability of recovery depends on the metal analyzed and the type of waste. It must be underline that an optimized

    2014-07-01

    Full Text Available Ecofeminism can be understood as the relationship between the manner in which women are treated in society and on how the environment is treated and protected. Ecofeminism starts from the idea according to which "nature is a feminist issue". The explanation for this is based on the feminist philosophy according to which the connection between woman and nature is a strong one, due to the fact that she is the one who gives birth, thus helping nature to regenerate itself. Without women, female plants and animals, the planet could not develop, perpetuate and the end would be death. Furthermore, another explanation related to the first is that animals and people in their capacity as mothers are able to provide a greater amount of love, care, protection, both to their offspring and to nature. This paper aims to analyze the manner in which women are harmed by the environmental degradation in Romania and also the principles that have governed and still govern the current economy. Nowadays society is lead largely by male gender persons. The main accusations against current policies is that they seek concrete and immediate results, such as those related to economic growth, inflation rate etc. in terms of strictly economic indicators such as: gross domestic product, net national product, gross national product etc.. On the contrary, ecofeminist policies suggest that the emphasis should be placed on quality of life issues, which within itself analyzes both economic and also social and environmental aspects. Is not this the reproach for decades now that is brought to current economic policies? The fact that they do not take into account issues related to environmental degradation, in time led to negative consequences in the world whose costs are unimaginable.

    Full Text Available On the basis of the latest statistics, the author estimates the present share of first- and second-generation immigrants in Slovenia’s population. After examining the quantity and intensity of those public efforts in Slovenia that have been focused on unresolved problems of the immigrants’ social and cultural integration, she continues to question the equality of immigrant minorities in Slovenia, and the sufficiency of the existing programs aimed at facilitating their integration with Slovenian society at large. She explains her doubts about the general assumption that a very clear distinction should be made between the rights of the autochthonous minorities and those of the immigrant ones as far as their special protection is concerned. In the third section of this article, the author discusses the social-ethnic stratification of Slovenian society and tries to look into the psychological background of the nationality/ethnicity statistics. She presents some aspects of the immigrants’ daily experience in Slovenian social, cultural, educational and working milieu, and points to the authorities’ attitude toward them. She comments on the burning issue of the “deleted residents”, and illustrates it with the experience of one of the persons involved. The fourth section, in which the most regular symptoms of Slovenian xenophobia are presented, consists of first-hand observations and focuses on the daily human attitude of the national majority towards the immigrant minorities. Finally the author compares the nature of the specific needs of Slovenians as a “European national minority” with the needs of the immigrant minorities in Slovenia.

    The injury to haemopoietic and lymphatic tissues produced by ionizing irradiation in various species of mammals including man is one of the major features of the biological effects of radiation (Bond et al. 1965,' Cottier, 1961). At the moment of injury and for a short time thereafter relatively little morphological evidence of cell damage in bone marrow other than cessation of cell division and DNA synthesis is seen. Within a few hours, however, depending on the level of exposure, major destruction of red bone marrow tissue can occur. In this chapter the histologic changes in bone marrow are summarized for correlation with the functional aspects of the change in the target tissue, particularly its cell renewal features and where possible the remarkable flux or migration of cells through bone marrow and lymphatic tissues. This latter topic of cellular traffic represents the outcome of extensive physiological studies on haemopoiesis and lymphopoiesis by mammalian radiobiologists. The initial injury, the structural changes and the physiological consequences are the first half of the radiation injury sequence. Regeneration also has morphological features of major importance to the understanding of radiation haematology. It is common to discuss radiation effects on biological materials from the point of view of external or internal sources of exposure. In addition exposure rate, whole body or partial body, type and quality of the ionizing source are features that must be taken into account. While these features are extremely important, the simplest approach to understanding histologic effects on the bone marrow is to assume acute penetrating whole-body exposure in the lethal range. With this background the differences related to variations in the conditions of exposure can usually be understood. The individual human or animal organism receiving the exposure must also be considered in the final outcome of the experience because age, sex, nutritional status and presence

    Full Text Available The purpose of this article is to outline the main economical and social benefits that can be obtained by adopting an ethical attitude of the organisations which use a performant environmental management. From the idea that the human being is the master of nature, it was passed to the view according to which the human being must ensure a balance between consumption and the use of resources. In order to achieve our goal we identified the factors that lead to long term or even permanent destructive effects over the environment and we briefly present the reasons for which the organizations adopt and implement environmental management systems. Also, the difficulties encountered in implementing environmental strategies have been briefly enumerated and the competitive and economic advantages that can be achieved by adopting an efficient environmental management and the main reasons that grant to the environmental management a special significance were exposed. This theoretical paper emphasizes the importance of the adoption by organizations of a "green behavior" and reveals correlations between sustainability, economic growth and environmental performance in organizations. The analysis of the ethical aspects of environmental management shows the links that can be created between the development of an ethical culture of organizations and the achievement of the environmental excellence. The research provides an overview of the concept of environmental ethics and encloses it within the scope of environmental management. Someone needs to explain why an increasing number of organizations, both large and small, are setting up environmental management systems, making environmental investments and reducing risks over and beyond legal requirements, even when the benefits are not at all obvious, even in the long run. Also, this paper provides some practical examples of organizations environmental problems and points out how these organizations adapted their

    Full Text Available The world practice of using agrochemicals for long periods, in an indiscriminated and abusive way, has been a concern of the authorities involved in public health and sustainability of the natural resources, as a consequence of environmental contamination. Agrochemicals refer to a broad range of insecticides, fungicides and herbicides, and among them stands out atrazine, a herbicide intensively used in sugarcane, corn and sorghum cultures, among others. Researches have demonstrated that atrazine has toxic effects in algae, aquatic plants, aquatic insects, fishes and mammals. Due to the toxicity and persistence of atrazine in the environment, the search of microbial strains capable of degrading it is fundamental to the development of bioremediation processes, as corrective tools to solve the current problems of the irrational use of agrochemicals. This review relates the main microbial aspects and research on atrazine degradation by isolated microbial species and microbial consortia, as well as approaches on the development of techniques for microbial removal of atrazine in natural environments.A prática mundial do uso de agroquímicos por períodos extensos, de maneira indiscriminada e abusiva, tem mobilizado as autoridades envolvidas em saúde pública e sustentabilidade de fontes naturais, como uma conseqüência da contaminação ambiental. Agroquímicos referem-se a uma ampla variedade de inseticidas, fungicidas e herbicidas, entre estes a atrazina, um herbicida intensivamente usado em culturas de cana-de-açúcar, milho, sorgo, entre outros. Pesquisadores têm demonstrado que a atrazina tem efeitos tóxicos em algas, plantas aquáticas, insetos aquáticos, peixes e mamíferos. Devido à toxicidade e à persistência da atrazina no ambiente, a busca de linhagens microbianas capazes de degradá-la é fundamental para o desenvolvimento de processos de biorremediação, com uma ferramenta corretiva para solucionar problemas decorridos do uso

Another important aspect of clinical efficacy of medications in space is the stability of pharmaceuticals. As the U.S. space program is moving toward extended Space Shuttle flights and beyond, to space station missions and planetary explorations, understanding how space flight affects organ systems and clinical pharmacology is necessary to optimize pharmacotherapeutics in space and ensure adequate safety and health of crewmembers.

    with propagation via the ionosphere of signals within the HF band. Several aspects are covered in this paper:

    a The directions of arrival and times of flight of signals received over a path oriented along the trough have

    been examined and several types of propagation effects identified. Of particular note, combining the HF observations

    with satellite measurements has identified the presence of irregularities within the floor of the trough that

    result in propagation displaced from the great circle direction. An understanding of the propagation effects that

    result in deviations of the signal path from the great circle direction are of particular relevance to the operation

    of HF radiolocation systems.

    Results are presented of a literature review to identify social and psychological aspects of abortion. The literature does not provide a true profile of women requesting abortions, but some characteristics emerge. Reasons for requesting abortion include economic problems, difficult previous pregnancies, general medical contraindications to pregnancy, marital conflicts, feelings of loneliness, professional aspirations, problems with existing children, and feelings of insecurity about the future. However, the same feelings are found among women carrying their pregnancies to term. Unplanned pregnancies are more common during periods of depression. Most authors have found about 1/2 of women seeking abortions to be single and about 1/2 to be under 25 years old. Religion does not appear to be a determining factor. 1 study of psychological factors in abortion seekers found that a large number of single women seeking abortion had suffered traumatic experiences in childhood and were seeking security in inappropriate amorous relationships. Helene Deutsch stressed the destructive impulses latent in all pregnancies. Others have cited the ambivalence of the desire for pregnancy and feelings of loss after abortion. Studies published after legalization of abortion in the US and France however have stressed the nearly total absence of moderate or severe psychiatric symptoms after abortion. Responses immediately after the abortion may include feelings of relief, guilt, indifference, or ambivalence. Secondary affects appear minor to most authors. Psychological effects do not appear to be influenced by age, marital status, parity, intelligence, occupation, existence of a later pregnancy, or concommitant sterilization. "Premorbidity" and coercion by spouse or family were most closely associated with psychological symptoms. Numerous authors have found about twice as many negative reactions among women undergoing abortion for medical reasons. Most patients undergoing abortions for

    Inside the industrial applications of the sealed radioactive sources, there are clearly exist two defined branches for which these materials are used: radioactive sources used in fixed equipment and in mobile ones. These devices are used in a countless of applications and every time with more advanced technological systems. This requires a permanent improvement inside the training of the responsible one and in turn it introduces an obligatory change to other intervention groups during the useful life of the device. The accident risks to those that are associate the use of these equipment, they are errors during the operation, undue use, maintenance carried out by personal without knowledge, flaws of human type or negligence and incidents happened during the transport. All these 'risks' its are surrounded of different groups of factors that influence during the safe use of the radioactive material, inside the installation of one way or another. Then it stands out the importance of implanting aspects of 'Safety Culture', evaluations of aptitude of the responsible one for the radiological safety, introduction of improvements in aspects of quality and communication of risks, chord to what indicates the normative of the Argentine Republic and the international requirements, which will be approached in the present work.

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

    2000-01-01

    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.

    Within the industrial applications of sealed radioactive sources, there are two clearly defined branches for which these materials are used: radioactive sources used in fixed and mobile equipment. These devices are used in a myriad of applications and each time with more technological advanced systems. This requires a permanent improvement on the training of the responsible, and introduces a mandatory exchange to other groups of intervention during the useful life of the device. Accident risks during the use of the equipment, although its rate of occurrence is low, are related to mistakes during operation, improper use, maintenance performed by staff without knowledge, human failures or oversights and incidents occurring during transport. All these risks are surrounded by different groups of factors that influence during the safe use of radioactive material within the installation. So, it is evidenced the importance of implementing aspects of the 'Safety Culture' and evaluations of suitability of the person responsible for radiation safety. In this paper we will refer to all the concepts that surround the election of the head of radioactive material, the factors involved during the operation, their training, the obligations of the installation, and responsible for environment and the technology.

    Following an accidental release of radionuclides to the atmosphere that leads to the contamination of large areas, a detailed and fast methodology to assess the prognosis of public exposure is needed, in order to estimate radiological consequences and propose and optimize decisions related to the protection of the public. The model ECOSYS has been chosen to integrate the SIEM, the Integrated Emergency System developed by IRD/CNEN, to assess the doses at the short, medium and long term to the public after an accidental contamination of rural areas. The objective of this work is to perform the adaptation of the model ECOSYS to be used in Brazil to assess public exposure and support decision processes regarding the implementation of protective measures but also to guide the need for studies and research aiming to improve the adequacy of estimates to the actual Brazilian situation. The area select for reference to this work consists on the 50 km radius area surrounding the Brazilian nuclear power plants, located at Angra dos Reis County, in the state of Rio de Janeiro. The methodology included the definition of criteria to select agricultural cultures and animals to be simulated, taking into account both the availability of the production at the selected area and the relevance of the food to the population regional diet. Radionuclides included in this study were {sup 137}Cs, {sup 90} Sr and {sup 131} I. A large survey has been performed to gather data related to both agricultural practices and behavior of radionuclides in the selected agricultural-systems. The results of simulation indicated the relevance of the knowledge of local aspects on the estimated doses. Important factors included the kind of products produced, seasonality, agricultural practices, animals feed practices, kind of soil, and ingestion habits of the population. (author)

    The response to an emergency situation involving ionizing radiation requires the joint participation of professionals from various kind of knowledge, belonging to public and private organizations (in the local, state and federal levels). The theme radiation tends to be an additional challenging factor - considering that it's, usually, remembered for its macabre and ominous aspect, in spite of the benefits provided by it - which makes the implementation of actions to protect the public, emergency professionals, the environment and property, very difficult. To this, we can add the complicating factor that, in most cases, the technician (holder of basic or advanced on the subject) is far !Tom the place where this action unfolds. The accident/incident takes the form of a radioactive source (sometimes orphaned, one that gone astray or even stolen) that is found by a person unaware of the risks to which they are being exposed or, let not forget about it, the non-observance of safety standards in industries and workplaces, by their own operators. Thus, before integrating emergency response plans with conventional plans specific to the prompt response to radiological emergencies, it is necessary that some measures had been anticipated and that some actions had, already, been planned - with the intention of mitigate health, psychological and economical damage, in ali of kind. To do this, since in the course of the second decade of the second millennium, and since you own a portable personal computer (Note or Netbook), or even with a mobile device (cellular) with a bit more resources, both of them previously updated, a responder (or even a qualified technician that is next to that fact) may already guide, at least, about a safety distances !Tom the source. Since he had knowledge about some characteristics of the source (its individual data), he can plan ahead about the possible serious situation that unfolds itself and emergency responders will find, when it get to the

    Phantoms are tools for simulation of organs and tissues of the human body in radiology and radiotherapy. This thesis describes the development, validation and, most importantly, the use of a physical head and neck phantom in radiology and radiotherapy, with the purpose of evaluating dose distribution using Gafchromic EBT2 film in 15 MV 3D conformal radiotherapy. The work was divided in two stages, (1) development of new equivalent tissues and improvement of the physical phantom, and (2) use of the physical phantom in experimental dosimetry studies. In phase (1) parameters such as mass density, chemical composition of tissues, anatomical and biometric measurements were considered, as well as aspects of imaging by computed tomography (CT) and radiological response representation in Hounsfield Units (HU), which were compared with human data. Radiological experiments of in-phantom simulated brain pathologies were also conducted. All those results matched human-sourced data, therefore the physical phantom is a suitable simulator that may be used to enhance radiological protocols and education in medical imaging. The main objective in phase (2) was to evaluate the spatial dose distribution in a brain tumor simulator inserted inside the head and neck phantom developed by the Ionizing Radiation Research Group (NRI), exposed to 15 MV 3D conformal radiotherapy, for internal dose assessment. Radiation planning was based on CT images of the physical phantom with a brain tumor simulator made with equivalent material. The treatment planning system (TPS), CAT3D software, used CT images and prescribed a dose of 200 cGy, distributed in three fields of radiation, in a T-shaped pattern. The TPS covered the planning treatment volume (PTV) with 97% of the prescribed dose. A solid water phantom and radiochromic Gafchromic EBT2 film were used for calibration procedures, generating a dose response curve as a function of optical density (OD). After calibration and irradiation, the film

  15. 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.

  16. Decentralised energy supply in 2020 - Commercial aspects

    International Nuclear Information System (INIS)

    Kleimaier, M.

    2007-01-01

    This comprehensive article summarises the commercial aspects of a study made by the German Association of Electrical, Electronic and Information Technologies VDE on the topic of decentralised energy supply in the year 2020. In a previous article, the technical aspects were examined. This article looks at the findings in connection with commercial aspects of the production of power in decentralised facilities including those using renewable sources of energy. The potential of these forms of electricity generation for the year 2020 is looked at both from the political and economical points of view. The general conditions prevailing for the implementation of decentralised power production in Germany such as the Renewable Energy Law and legislation on combined heat and power generation are discussed. The influence of electricity tariffs and competition in the market is examined, as are various scenarios and concepts for the supply of both power and heating energy. Ways of providing a sustainable energy supply without having to subsidise particular concepts are discussed

  17. 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)

    With the aim of exchanging information on various subjects about radiation protection and designing a site where the members can send and receive information on courses, scientific activities, articles, technical opinions, commentaries and everything that promotes the communication, collaboration and integration, the 15th March 2002 the networking: 'radioproteccion' is created with 11 persons from 11 countries. 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

  1. Microeconomic aspects of energy crops cultivation

    International Nuclear Information System (INIS)

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

    1992-01-01

    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.

  5. 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)

    1989-02-01

    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.
