    Cloutier, R.J.

    1980-01-01

    All health physicists are familiar with the radium dial painter episode of the early 1900s and how one of today's primary radiation limits was set after studying both the health effects of these workers. The social history of this event is not as well known to health physicists. This paper tells of the efforts by Florence Kelley of the National Consumers League and others on behalf of the dial painters and of the events that led to Kelley's interest in the problem. Known as the 'Impatient Crusader', Florence Kelley worked to have legislation passed that would eliminate the radiation hazards of dial painting and to obtain compensation for those who were injured.

  2. Polonium-210 concentration in the hair of 51 radium dial painters

    Energy Technology Data Exchange (ETDEWEB)

    Erkang, Zeng; Nanxiang, Li

    1984-07-01

    The /sup 210/Po concentration in the hair of 51 radium dial painters (one group of 29 male, and the another group of 22 female) was reported in this paper. It was found that the /sup 210/Po concentration in the hair of both the male and female painters were significantly higher than that of the controls. A correlation has also been observed between the /sup 210/Po concentration in the hair and the working ages of the male painters.

  3. Dose-effect relationships for the US radium dial painters

    International Nuclear Information System (INIS)

    Thomas, R.G.

    1995-01-01

    Dose-response data are presented from a large percentage of the US workers who were exposed to radium through the painting of luminous dials. The data in this paper are only from females, because very few males worked in this occupation. Log-normal analyses were done for radium-induced bone sarcomas and head carcinomas after the populations of the respective doses were first determined to be log-normally distributed. These populations included luminisers who expressed no radium-related cancerous condition. In this study of the female radium luminisers, the most important data concerning radiation protection are probably from workers who were exposed to radium but showed no cancer incidence. A total of 1391 subjects with average measured skeletal doses below 10 Gy are in this category. A primary purpose is to illustrate the strong case that 226,228 Ra is representative of those radionuclides that exemplify in humans a 'threshold' dose, a dose below which there has been no observed health effects on the exposed individual. Application of a threshold dose for radium deposited in the skeleton does not mean to imply that any other source of skeletal irradiation should be considered to follow a similar pattern. Second, a policy issue that begs for attention is the economic consequence of forcing radiation to appear as a highly toxic insult. It is time to evaluate the data objectively instead of formatting the extrapolation scheme beforehand and forcing the data to fit a preconceived pattern such as linearity through the dose-effect origin. In addition, it is time to re-evaluate (again) variations in background radiation levels throughout the world and to cease being concerned with, and regulating against, miniscule doses for which no biomedical effects on humans have ever been satisfactorily identified or quantified.

  4. Effects of radium-226 on bone from a radium dial painter at 12 years and 55 years after ingestion

    International Nuclear Information System (INIS)

    Henning, C.B.; Lloyd, E.L.

    1982-01-01

    Samples of bone from two different sites in a female former radium dial painter, collected 43 years apart, were examined with the electron microscope. The results show further evidence for the presence of a fibrotic layer of tissue covering bone mineral which separates the bone lining cells from the source of the radioactive deposits in bone mineral. This work further confirms our contention that many of the cells at risk for the production of bone tumors probably lie outside the single bone lining cell layer which characteristically lies about 1 to 2 μm away from bone mineral in normal control bone

  5. Unjustly forgotten painter

    Full Text Available This paper talks about a painter, Sima Čemerikić, whose miscellaneous and rich work, due to unexplained circumstances, has remained out of reach of professional and general public until now. He was born in 1906 in Prizren where he completed junior high-school in 1923. Afterwards, he moved to Skopje. He entered a state School of Art in Belgrade in 1924. Having graduated in 1929 he spent a short time training in Venice. Upon his arrival in Skopje, his artistic career began. Along with other painters from Macedonia, he equally fills the pages of Macedonian modern art. He remained in this city until the capitulation of that country. The other part of his life, from 1941 to his death in 1973, he spent in Niš. The work of Sima Čemerikić is separated into two periods. The first one, from Skopje, lasted from his graduation from the Art School in 1929 to the beginning of the World War II. The second period, from Niš, begins after his family had moved to Niš and ends with his death in 1973. He left hundreds of drawings and a number of paintings behind as well as a dozen of pastels and hundreds of aquarelles. Let me mention some of the paintings: Landscape of the sea, Landscape of Makarska, A Theme from Bol on Brač, Pain, A Little Gypsy, Portrait of The Sister, Fish, Chrysanthemum, Roses, Books and Apples, Tulips.

    2008-01-01

    In this essay Dr Valter Rukavina (Rijeka 1896-1972), excellent specialist in infectious diseases and professor of the Rijeka University School of Medicine, is presented as successful amateur painter. He had been refining his talent through relentless practice since the school days, complementing it with skills and advice from established painters he associated with. He favoured figurative, realistic and somewhat romantic expression for his themes such as coastal landscapes, marinas, Quarnero sceneries, still life in tempera or oil, and drawings in ink or sepia. Despite partial colour blindness, he successfully used colour. He featured in a number of group exhibitions such as that of amateur painters of Rijeka in 1950, of painters physicians of Yugoslavia (Zagreb, 1956), in the Second International Exhibition of Contemporary Art (Florence, 1964), exhibition of the Rijeka branch of the Croatian Association of Visual Artists (Belgrade, 1966), and the 1969 exhibition in Opatija. His native city hosted two one-man exhibitions, the first retrospective in 1971, while he was still alive, and the second posthumous in 2007, with a good selection of his life's work.

    The prevalence of different measurements of respiratory illness among construction painters was examined and the relation between respiratory illness and employment as a painter assessed in a cross sectional study of current male members of two local affiliates of a large international union of painters. Respiratory illness was measured by questionnaire and spirometry. Longer employment as a painter was associated with increased prevalence of chronic obstructive disease and an interactive effect was observed for smoking and duration of employment as a painter. Multiple regression analysis showed a significant association between years worked as a painter and a decrement in FEV1 equal to about 11 ml for each year worked. This association was larger among painters who had smoked. The prevalence of chronic bronchitis was significantly associated with increased use of spray application methods.

    2003-01-01

    The Dial-a-Ride problem is a Vehicle Routing problem in its most general form. The problem was formulated in the beginning of the 1970's and since then a large number of researchers have worked on developing efficient algorithms for use in automated planning of Dial-a-Ride transportation systems....... In a Dial-a-Ride transportation system, passengers request a trip between two stops with either a desired time of departure from the pickup stop or a desired time of arrival at the destination. The time windows at the stops are then calculated by the operator based on additional parameters such as maximum...... to the problem. The metod used in this thesis is based on a clustering first insertion second technique developed at CRT in Canada in the mid 1980's. The algorithm is extended to include constraints imposed by a practical Dial-a-Ride problem at a Danish transportation operator. These constraints are mainly...

  12. Radium dial workers

    Rowland, R.E.; Lucas, H.F. Jr.

    1982-01-01

    The population of radium dial workers who were exposed to radium 30 to 50 years ago are currently being followed by the Center for Human Radiobiology at the Argonne National Laboratory. It is not clear that radium has induced additional malignancies in this population, other than the well-known bone sarcomas and head carcinomas, but elevated incidence rates for multiple myeloma and cancers of the colon, rectum, stomach, and breast suggest that radium might be involved. Continued follow-up of this population may resolve these questions. Finally, the question of the effect of fetal irradiation on the offspring of these women remains to be resolved. No evidence exists to suggest that any effects have occurred, but there is no question that a chronic irradiation of the developing fetus did take place. No formal follow-up of these children has yet been initiated

  13. Overview of occupational cancer in painters in Korea.

    2018-01-01

    Comprehensive consideration is necessary for setting guidelines to evaluate evidence of occupational cancer in painters due to work-related exposure to carcinogens in paint (a phenomenon termed herein as "work-relatedness"). The aim of the present research is to perform a comprehensive review and to suggest criteria for the provision of compensation for occupational neoplasm among painters in Korea. In order to perform a comprehensive review, this study assessed and evaluated scientific reports of carcinogenicities from the International Agency for Research on Cancer (IARC) and the Industrial Injuries Advisory Council (IIAC), as well as reviewed the existing literature about occupational exposure among painters in Korea and the epidemiologic investigations of claimed cases of cancer among painters in Korea. The IARC declares that occupational exposures in commercial painting are classified as Group 1 carcinogens for lung cancer and bladder cancer among painters. The epidemiologic studies show consistent causal relationships between occupational exposure in painters and cancers such as lung cancer [meta relative risk: 1.34 (95% confidence intervals (CIs): 1.23-1.41)] and bladder cancer [meta relative risk: 1.24 (95% CIs: 1.16-1.33)]. In reviewing occupational cancer risks for commercial painters, the Industrial Injuries Advisory Council (IIAC) confirms occupational cancer risks for lung and bladder cancer among commercial painters. According to the IIAC, however, the elevated cancer risks reported in existing literature are not doubled in either lung or bladder cancer in commercial painters relative to the risks of these cancers in the general population. Based on our review of existing Korean articles on the topic, painters are exposed to potential carcinogens including polycyclic aromatic hydrocarbons (PAHs), benzene, hexavalent chrome, crystalized silica, asbestos, and other agents, and relative levels are estimated within commercial painting processes.

  14. Adolf Sandoz, an Orientalist Painter in Algeria

    Directory of Open Access Journals (Sweden)

    Wójcik, Agata

    2017-04-01

    Full Text Available Adolf Karol Sandoz was a 19th-century Polish artist who spent his life and developed his artistic career in France. In Paris, he studied painting and architecture, and worked as a professional illustrator. He can also be linked with a circle of artist-travellers, who searched for new sources of inspiration in the Orient. In 1879 and 1881, Sandoz travelled in Algeria. He described his impressions from the first journey in vividly written memoires published by the Krakow journal "Czas". His travels inspired several genre paintings, including: "Interior of a house in Biskra", "Dancer from the Uled Nail tribe", "Arab woman by a cradle", "Morning in the Sahara", "Evening in the Sahara", "Oasis", "On the Oued riverbank at El Kantara oasis", and "Sheik Mistress of El Kantara". At present, his works emerge at art auctions, are known from reproductions, or only from descriptions. Sandoz exhibited in Paris, Warsaw, Krakow, and Lviv, where he was appreciated by art critics. The aim of this article is to introduce Sandoz’s journey to Algeria, analyse his paintings with exotic subject matter, and locate them within a wider context of orientalist painting. It will also present the history of artistic travel to Algeria undertaken by 19th-century painters, including those from Poland.

  15. Coping with crisis. Career strategies of Antwerp painters after 1585

    David van der Linden

    2015-12-01

    Full Text Available This article explores how painters responded to the crisis on the Antwerp art market in the 1580s. Although scholarship has stressed the profound crisis and subsequent emigration wave, prosopographical analysis shows that only a minority of painters left the city. Demand for Counter-Reformation artworks allowed many to pursue their career in Antwerp, while others managed to survive the crisis by relying on cheap apprentices and the export of mass-produced paintings. Emigrant painters, on the other hand, minimised the risk of migration by settling in destinations that already had close artistic ties to Antwerp, such as Middelburg. Prosopographical analysis thus allows for a more nuanced understanding of artistic careers in the Low Countries.

    The work has been aimed at investigating the effects of organic solvent-toluene-upon the painters of the Building Joinery Factory. Studies carried out during 1978-1980 showed an increased level of toluene metabolite (hippuric acid) in painters' urine, as compared to the environmental control group. The highest level of hippuric acid in painters' urine was found in the first period (first six months) of their job. This was not related to an increase in toluene vapours at the workplace. In painters' blood some irregular and rather small modifications of enzymatic activity were exhibited.

  17. Austrian Painter Leopold Kupelwieser and Bishop Josip Juraj Strossmayer

    Directory of Open Access Journals (Sweden)

    Ljerka Dulibić

    2016-01-01

    Full Text Available All 20th-century chronologies of the collector’s activity of Bishop Josip Juraj Strossmayer (1815-1905 and overviews of the evolution of today’s Strossmayer’s Gallery of Old Masters at the Croatian Academy of Sciences and Arts mention the bishop’s cooperation with the Austrian Nazarene painter Leopold Kupelwieser (1796-1862, father of Paul Kupelwieser, the former owner of the Brijuni islands. This episode from the “prehistory” of Strossmayer’s Gallery has hitherto been known only as a brief notice repeated in almost identical formulations: “In 1857, the bishop sent the first larger group of paintings to Vienna in order to be restored under the supervision of painter Leopold Kupelwieser.” Research of archival documents mentioning the cooperation between Bishop Strossmayer and painter Kupelwieser has now been complemented with an overview of Kupelwieser’s activity in Croatia, with an aim of promoting the preservation and evaluation of this segment of his painting oeuvre. Besides paintings ordered by Strossmayer (presently at the Diocesan Museum of Zagreb, Kupelwieser produced two paintings for Croatian churches independently of his cooperation with the bishop (for the church of St Stephen of Hungary, today’s church of the Immaculate Conception of the Blessed Virgin Mary in Nova Gradiška, and for the chapel of St Peter and Paul in Dvor na Uni. Two more paintings are preserved on the Brijuni islands that do not directly belong to Kupelwieser’s oeuvre yet are closely linked to him.

  18. Exposure Characteristics of Construction Painters to Organic Solvents

    2016-03-01

    Conclusion: From this study, we recognized that construction painters are exposed to various solvents, including carcinogens and reproductive toxins, and the levels of TVOC concentration in many of the painting tasks exceeded the exposure limits. Construction workers need to be protected from chemical agents during their painting works by using personal protective devices and/or work practice measures. Additional studies should focus on the exposure assessment of other hazards for construction workers, in order to identify high-risk tasks and to improve hazardous work environments.

    Pacific Northwest National Laboratory's Infrared Sensors team is focused on developing methods for standoff detection of nuclear proliferation. In FY05, PNNL continued the development of the FM DIAL (frequency-modulated differential absorption LIDAR) experiment. Additional improvements to the FM DIAL trailer provided greater stability during field campaigns which made it easier to explore new locations for field campaigns. In addition to the Hanford Townsite, successful experiments were conducted at the Marine Science Laboratory in Sequim, WA and the Nevada Test Site located outside Las Vegas, NV. The range of chemicals that can be detected by FM DIAL has also increased. Prior to FY05, distributed feedback quantum cascade lasers (DFB-QCL) were used in the FM DIAL experiments. With these lasers, only simple chemicals with narrow (1-2 cm-1) absorption spectra, such as CO2 and N2O, could be detected. Fabry-Perot (FP) QC lasers have much broader spectra (20-40 cm-1) which allows for the detection of larger chemicals and a wider array of chemicals that can be detected. A FP-QCL has been characterized and used during initial studies detecting DMMP (dimethyl methylphosphonate).

    Aggarwal, Neelam; Doiron, Theodore D.; Sanghera, Paramjeet S.

    1993-11-01

    In this paper, we present the development of a fast and robust vision system which, in conjunction with the Dial Gage Calibration system developed by AKO Inc., will be used by the U.S. Army in calibrating dial gage torque wrenches. The vision system detects the change in the angular position of the dial pointer in a dial gage. The angular change is proportional to the applied torque. The input to the system is a sequence of images of the torque wrench dial gage taken at different dial pointer positions. The system then reports the angular difference between the different positions. The primary components of this vision system include modules for image acquisition, linear feature extraction and angle measurements. For each of these modules, several techniques were evaluated and the most applicable one was selected. This system has numerous other applications like vision systems to read and calibrate analog instruments.

    PURPOSE: The present study aimed to estimate possible differences in upper body muscular load between male and female house painters performing identical work tasks. Sex-related differences in muscular load may help explain why women, in general, have more musculoskeletal complaints than men....... METHODS: In a laboratory setting, 16 male and 16 female house painters performed nine standardised work tasks common to house painters. Unilateral electromyography (EMG) recordings were obtained from the supraspinatus muscle by intramuscular electrodes and from the trapezius, extensor and flexor carpi...... radialis muscles by surface electrodes. Relative muscular loads in %EMGmax as well as exerted force in Newton, based on ramp calibrations, were assessed. Sex differences were tested using a mixed model approach. RESULTS: Women worked at about 50% higher relative muscular loads than men in the supraspinatus...

    Full Text Available The article deals with the figure of the painter Henrika Šantel as it appears within national art history discourse and critics. Besides the abatement of women’s role in art history of the late 19th and early 20th centuries, the biased interpretation, contaminated with patriarchal gender ideology, is evident. With the revision of sources, biographical contextualisation of artistic production, and the inclusion of feminist theory of art practice, we aim to shed light on the historical contribution of the painter.

    2017-01-01

    Full Text Available In the present research we explored the presence of schizotypal traits in painters. Furthermore, the relations of schizotypy and creativity-related variables (intelligence, creativity and creative productivity were analyzed. Study participants were divided into the criterion (132 students of art academy and art high school and control group (119 psychology students and members of grammar school. Two hypotheses were set: 1 schizotypal traits are more pronounced in painters than in control group; 2 schizotypy is more closely associated with the creativitylinked variables in the criterion than in control group. Schizotypy was operationalized by Disintegration construct and measured via DELTA 10 inventory. Intelligence was assessed by Advanced Progressive Matrices-18; creativity was measured by the same labeled scale from HEXACO-PI-R inventory and creative productivity was explored by a set of questions regarding the frequency of creative behavior. Results showed that Magical thinking, Enhanced awareness, Somatoform Dysregulation, Perceptual distortions and Social anhedonia were the schizotypal traits which were more pronounced in painters as compared to the control group. Factor analyses performed in each group separately revealed a latent component loaded both with schizotypal traits, creativity and creative productivity, but only in the group of painters: schizotypy and creativity were not so closely related in the control group. Thus, the study hypotheses were largely confirmed. Results provide a more detailed understanding of the relations between schizotypy and creativity.

    Dermal contact with isocyanate-based coatings may lead to systemic respiratory sensitization. The most common isocyanates found in sprayed automotive coatings are monomeric and oligomeric 1,6-hexamethylene diisocyanate (HDI) and isophorone diisocyanate (IPDI). Most spray painters use thin (4–5 mil) latex gloves that are not effective at preventing dermal exposures when spraying isocyanate paints. Personal interviews with collision repair industry personnel and focus groups with spray painters were held to characterize risk awareness, to examine perceptions and challenges concerning protective glove use and selection, and to generate ideas for protective glove use interventions. The most popular gloves among spray painters were thin (4–5 mil) and thick (14 mil) latex. We found that medium to thick (6–8 mil) nitrile were not always perceived as comfortable and were expected to be more expensive than thin (4–5 mil) latex gloves. Of concern is the users’ difficulty to distinguish between nitrile and latex gloves; latex gloves are now sold in different colors including blue, which has traditionally been associated with nitrile gloves. Even though spray painters were familiar with the health hazards related to working with isocyanate paints; most were not always aware that dermal exposure to isocyanates could contribute to the development of occupational asthma. There is a need for more research to identify dermal materials that are protective against sprayed automotive coatings. Automotive spray painters and their employers need to be educated in the selection and use of protective gloves, specifically on attributes such as glove material, color, and thickness.

    This paper describes the results from a series of ambient vibration studies conducted on the Painter Street Overpass in Rio Dell, California. Painter Street is a two-span, skewed reinforced concrete bridge with two single piers near the middle and monolithic abutments, typical of bridge overpasses...... from analyses of selected strong motion records. The magnitude of the events investigated ranges from ML=4.4 to ML=6.9, which produced accelerations of up to 0.54g at the free field site, 1.3g at the abutments, and 0.86g on the deck. The results of this study indicate that the overall dynamic...... properties of the bridge are very sensitive to the level of ground shaking and that soil-structure interaction is very important for this type structural system. Although the superstructure exhibited a nearly elastic response, the motions at the abutments and base of piers were significantly different...

    Sundin, M.; Roslund, C.

    Several generations of Swedish children have become acquainted with the world of fairy-tales through illustrations by the painter John Bauer in the Christmas magazine Goblins and Trolls. Next to his portrayal of grotesque but humorous trolls, his paintings of the Moon and the starry sky are among those best remembered. These pictures have inspired very many Swedes to take pleasure in the beauty of the stars and the movement of the Moon.

  2. Effect of reduced use of organic solvents on disability pension in painters.

    2017-11-01

    To investigate whether the decreased use of paints based on organic solvents has caused a decreased risk for neuropsychiatric disorders in painters by studying their incidence in disability pensions. The incidence of disability pension in Swedish painters who had participated in health examinations between 1971 and 1993 was studied through linkage with Swedish registers of disability pension over 1971-2010 and compared with the incidence in other construction workers as woodworkers, concrete workers and platers. When phasing out began in the 1970s, about 40% of paints were based on organic solvents and it had decreased to 4% in 1990s. The analysis was adjusted for age, time period, body mass index and smoking. The painters (n=23 065) had an increased risk of disability pension due to neurological diagnosis (n=285, relative risk (RR) 1.92, 95% CI 1.67 to 2.20) and psychiatric diagnosis (n=632, RR=1.61, 95 % CI 1.42 to 1.82). For neurological disorders there was a time trend with a continuously decreasing risk from 1980 onwards, but there was no such trend for psychiatric disorders. High exposure to organic solvents increased the risk for disability pension in neurological disorders, and the risk decreased when the use of organic solvents decreased. The painters also had an increased risk of disability pension due to psychiatric disorders, but the causes have to be further investigated. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  3. Painterly rendered portraits from photographs using a knowledge-based approach

    Science.gov (United States)

    DiPaola, Steve

    2007-02-01

    Portrait artists using oils, acrylics or pastels use a specific but open human vision methodology to create a painterly portrait of a live sitter. When they must use a photograph as source, artists augment their process, since photographs have: different focusing - everything is in focus or focused in vertical planes; value clumping - the camera darkens the shadows and lightens the bright areas; as well as color and perspective distortion. In general, artistic methodology attempts the following: from the photograph, the painting must 'simplify, compose and leave out what's irrelevant, emphasizing what's important'. While seemingly a qualitative goal, artists use known techniques such as relying on source tone over color to indirect into a semantic color temperature model, use brush and tonal "sharpness" to create a center of interest, lost and found edges to move the viewers gaze through the image towards the center of interest as well as other techniques to filter and emphasize. Our work attempts to create a knowledge domain of the portrait painter process and incorporate this knowledge into a multi-space parameterized system that can create an array of NPR painterly rendering output by analyzing the photographic-based input which informs the semantic knowledge rules.

  4. Effects of exposure to ethylene glycol ethers on shipyard painters: II. Male reproduction.

    Welch, L S; Schrader, S M; Turner, T W; Cullen, M R

    1988-01-01

    To determine whether 2-ethoxyethanol (2-EE) and 2-methoxyethanol (2-ME) affected the reproductive potential of exposed men, we examined the semen of 73 painters and 40 controls who work in a large shipyard. An industrial hygiene survey was performed to characterize the work environment. The men supplied information on demographic characteristics, medical conditions, personal habits, and reproductive history; underwent a physical examination; and provided a semen sample. Semen samples were analyzed for pH, volume, turbidity, liquidity, viability by stain exclusion and hypo-osmotic stress, sperm density and count per ejaculate, motility using a videotape technique, morphology, and morphometry. Serum was analyzed for testosterone, FSH, and LH. The industrial hygiene survey revealed that the painters were exposed to 2-EE at a time-weighted average (TWA) of 0-80.5 mg/m3 with a mean of 9.9 mg/m3, and to 2-ME at a TWA of 0-17.7 mg/m3 with a mean of 2.6 mg/m3. Painters had an increased prevalence of oligospermia and azoospermia and an increased odds ratio for a lower sperm count per ejaculate, while smoking was controlled. This finding is consistent with prior animal studies and with one human study. Potential biases and confounding of the data are discussed.

    2011-06-01

    Full Text Available Science centers serve a number of goals for visitors, ideally providing experiences that are educational, social, and meaningful. This paper describes SunDial, a handheld application developed for families to use at a science center. Inspired by the idea of geocaching, the high-tech treasure hunting game that utilizes GPS technologies, SunDial asks families to use a single handheld device to locate and participate in a series of learning modules around the museum. Observations of 10 families suggest that it supports rich informal science education experiences, provides insights about families’ interaction patterns around and with single handheld devices, and demonstrates the value of navigation as an educational experience. Further, using recently released guidelines for Informal Science Education (ISE experiences to inform the design process proved valuable, tying features of the technology to educational and social goals, and giving evidence that explicit reference to these guidelines can improve ISE experiences and technologies.

  15. Indoor radon and lung cancer in the radium dial workers

    International Nuclear Information System (INIS)

    Neuberger, J.S.; Rundo, J.

    1996-01-01

    Internally deposited radium has long been known to have tumorigenic effects in the form of sarcomas of the bone and carcinomas of the paranasal sinuses and mastoid air cells. However, the radium dial workers were also exposed to radiation hazards other than that occurring from ingestion of the radium paint, viz., external gamma radiation and elevated concentrations of airborne radon. The uranium miners were also exposed to high concentrations of radon in the 1950s and later, and numerous cases of lung cancer have occurred in that population. However, unlike the atmosphere in the uranium mines, the air in the dial painting plants was probably rather clean and perhaps not much different from the air in many houses. In view of the current concern over the possibility of lung cancer fin the general population being caused by radon (progeny) in houses, it is important to examine the mortality due to this usually fatal disease in the dial workers and to attempt to relate it to their exposure to radon, to the extent that this is possible

    Methane is a potent greenhouse gas and on a per molecule basis has a warming influence 72 times that of carbon dioxide over a 20 year horizon. Therefore, it is important to look at near term radiative effects due to methane to develop mitigation strategies to counteract global warming trends via ground and airborne based measurements systems. These systems require the development of a time-resolved DIAL capability using a narrow-line laser source allowing observation of atmospheric methane on local, regional and global scales. In this work, a demonstrated and efficient nonlinear conversion scheme meeting the performance requirements of a deployable methane DIAL system is presented. By combining a single frequency 1064 nm pump source and a seeded KTP OPO more than 5 mJ of 1.6 µm pulse energy is generated with conversion efficiencies in excess of 20%. Even without active cavity control instrument limited linewidths (50 pm) were achieved with an estimated spectral purity of 95%. Tunable operation over 400 pm (limited by the tuning range of the seed laser) was also demonstrated. This source demonstrated the critical needs for a methane DIAL system motivating additional development of the technology.

  17. Airborne UV DIAL Measurements of Ozone and Aerosols

    2000-01-01

    The NASA Langley Research Center's airborne UV Differential Absorption Lidar (DIAL) system measures vertical profiles of ozone and aerosols above and below the aircraft along its flight track. This system has been used in over 20 airborne field missions designed to study the troposphere and stratosphere since 1980. Four of these missions involved tropospheric measurement programs in the Pacific Ocean with two in the western North Pacific and two in the South Pacific. The UV DIAL system has been used in these missions to study such things as pollution outflow, long-range transport, and stratospheric intrusions; categorize the air masses encountered; and to guide the aircraft to altitudes where interesting features can be studied using the in situ instruments. This paper will highlight the findings with the UV DIAL system in the Pacific Ocean field programs and introduce the mission planned for the western North Pacific for February-April 2001. This will be an excellent opportunity for collaboration between the NASA airborne mission and those with ground-based War systems in Asia Pacific Rim countries to make a more complete determination of the transport of air from Asia to the western Pacific.

    Although Renaissance artists were skilled in representing normal anatomy, a close look at some paintings reveals anatomical variations in the depiction of the feet of human figures. A systematic review has identified 25 paintings by five artists in which the presumptive medico-artistic diagnosis of congenital or acquired foot deformity seems to be varyingly present. The connection between these five painters and what factors have influenced artists' style in the depiction of such deformities is discussed. The possible iconography and medical-historical meaning of such variations, as well as the possibility of artistic licence and real representation that drove the painters to depict these deformities, is explored and debated.

    Nehrir, A. R.; Ismail, S.

    2012-12-01

    Water vapor plays a key role in many atmospheric processes affecting both weather and climate. Airborne measurements of tropospheric water vapor profiles have been a longstanding observational need to not only the active remote sensing community but also to the meteorological, weather forecasting, and climate/radiation science communities. Microscale measurements of tropospheric water vapor are important for enhancing near term meteorological forecasting capabilities while mesoscale and synopticscale measurements can lead to an enhanced understanding of the complex coupled feedback mechanisms between water vapor, temperature, aerosols, and clouds. To realize tropospheric measurements of water vapor profiles over the microscale-synopticscale areas of meteorological interest, a compact and cost effective airborne micropulse differential absorption lidar (DIAL) is being investigated using newly emerging semiconductor based laser technology. Ground based micropulse DIAL (MPD) measurements of tropospheric water vapor and aerosol profiles up to 6 km and 15 km, respectively, have been previously demonstrated using an all semiconductor based laser transmitter. The DIAL transmitter utilizes a master oscillator power amplifier (MOPA) configuration where two semiconductor seed lasers are used to seed a single pass traveling wave tapered semiconductor optical amplifier (TSOA), producing up to 7μJ pulse energies over a 1 μs pulse duration at a 10 kHz pulse repetition frequency (PRF). Intercomparisons between the ground based instrument measurements and radiosonde profiles demonstrating the MPD performance under varying atmospheric conditions will be presented. Work is currently ongoing to expand upon the ground based MPD concept and to develop a compact and cost effective system capable of deployment on a mid-low altitude aircraft such as the NASA Langley B200 King Air. Initial lab experiments show that a two-three fold increase in the laser energy compared to the ground

    2015-01-01

    Full Text Available The interest in European masters from the past was a phenomenon related to the development of the artistic careers of many artists in Australia at the end of the nineteenth and beginning of the twentieth century. More than that, the copying or emulation of great works of art was seen to be a necessary part of an artist’s training1. This paper looks at Hugh Ramsay and his fascination with the painting Las Meninas (1656 by Velázquez as part of a larger study into understanding how the Spanish in uence was re ected in Australian art. Ramsay introduced elements from Las Meninas into his Portrait of the artist standing before easel, which took him to personify the role of the painter as Velázquez.

    Full Text Available Resumen El objetivo de este escrito es examinar cómo se plantea una cierta dialéctica material en el conjunto llamado la Mansana de Chinati, construido por el escultor Donald Judd en la ciudad de Marfa, Texas, a partir del año 1974, comparándolo con las dos viviendas que realiza el arquitecto Philip Johnson en su propiedad de New Canaan, Connecticut, en torno al año 1950. Tanto en New Canaan como en la Mansana de Chinati existe una  oposición, una dialéctica, entre una arquitectura industrial y otra artesana, tanto Philip Johnson como Donald Judd consideran que existe una arquitectura principal, la realizada con materiales y técnicas industriales, y otra subalterna o de servicio, la construida con piezas de arcilla y técnicas artesanales. Esta segunda arquitectura encarnará las cualidades asociadas con la pobreza, la abundancia material y la clausura espacial. Sin  embargo, esta exhibición de pobreza no tiene como fin los propios edificios domésticos construidos artesanalmente, ya sea con adobe o con ladrillo, sino que estará al servicio de esa otra arquitectura, construida con técnicas industriales, a la que se exige renunciar a la comodidad y el confort o cuando menos ocultarlos bajo la forma de una radical austeridad.

    Apatite fission track results are reported for 26 outcrop samples from the Mt Painter Inlier, Mt Babbage Inlier and adjacent Neoproterozoic rocks of the northwestern Curnamona Craton of South Australia. Forward modelling of the data indicates that the province experienced variable regional cooling from temperatures >110deg C during the Late Palaeozoic (Late Carboniferous to Early Permian). The timing of this cooling is similar to that previously reported from elsewhere in the Adelaide Fold Belt and the Curnamona Craton, suggesting that the entire region underwent extensive Late Palaeozoic cooling most likely related to the waning stages of the Alice Springs or Kanimblan Orogenies. Results from the Paralana Fault Zone indicate that the eastern margin of the Mt Painter Inlier experienced a second episode of cooling (∼40-60deg C) during the Paleocene to Eocene. The entire region also experienced significant cooling (less than ∼40deg C) during the Late Cretaceous to Palaeogene in response to unroofing and/or a decrease in geothermal gradient. Regional cooling/erosion during this time is supported by: geomorphological and geophysical evidence indicating Tertiary exhumation of at least 1 km; Eocene sedimentation initiated in basins adjacent to the Flinders and Mt Lofty Ranges sections of the Adelaide Fold Belt; and Late Cretaceous - Early Tertiary cooling previously reported from apatite fission track studies in the Willyama Inliers and the southern Adelaide Fold Belt. Late Cretaceous to Palaeogene cooling is probably related to a change in stress field propagated throughout the Australian Plate, and driven by the initiation of sea-floor spreading in the Tasman Sea in the Late Cretaceous and the Eocene global plate reorganisation.

    1999-07-01

    A miniature CO2 DIAL system has been constructed. Dimension of the system are 500 X 450 X 240 mm, its mass is only 28 kg. The system consists of two tunable TEA CO2 lasers, receiving optics, IR detector, signal processing electronics and single chip microcomputer with display. The lasers are tuned manually by means of micrometric screw and are capable to generate pulses on more than 50 CO2 laser lines. The output energy is 50 mJ. The system was tested using various toxic gases and simulants, mostly at range 300 m, most of the measurements were done using pyrodetector in the receiver. The system shows good sensitivity, but it exhibits substantial instability of zero concentration. In the next stage the work will be concentrated on use of high-sensitivity MCT detector in the receiver and implementation of automatic tuning of lasers to the system.

    Full Text Available A Camaldolese painter, Father Venanzio da Subiaco (around 1570-1659, was active in Poland from 1624 to 1632, when he stayed in the hermitages at Bielany, near Cracow, and at Rytwiany. His name has been familiar to Polish scholars since 1871 (L. Zarewicz, and in 1952 his first brief monograph was written by Witold Urbanowicz, devoted, however, merely to his achievements in Poland. The monograph was later supplemented and verified by other researchers (J. Z. Łoziński and T. Przypkowski, W Kret., A. Ryszkiewicz, A. Małkiewicz. Venanzio’s work accomplished in Italy remained iong unknown. It was only in 1995 that Lucilia Conigliello organized an exhibition in Poppi featuring 14 paintings by Venanty, which she discovered in a Camaldolese hermitage and coenobium in Camaldoli. In the catalogue she discussed his 34 Italian works. In a catalogue of another exhibition of the Baroque art in Castentino (Poppi 2001, Conigliello included a short monograph of the painter, presenting his art both from the Italian and Polish period. The aim of this paper is to present a critical overview of the present state of research on Venanzio. His art created prior to joining the Order in 1618 remains unknown. As a Camaldolese monk he worked almost entirely for the congregation and sporadically for people connected with it, which limited the iconography of his paintings to religious themes. The artist’s preserved works include three sets of mural painitng (Monte Rua, near Padua, Bielany, Rytwiany and 50 oil paintings, 10 of which are in Polish monasteries. Their style bears influence of Caravaggio and is characterized by certain conservatism. The artist was also inspired by the paintings of great Renaissance masters, especially Titian, through the mediation of graphics. An important contribution of Venanzio was creating an iconographical canon of the Camaldolese church painting decoration, which was accomplished by the artist during his stay in Poland and

    Full Text Available El presente artículo trata de la dialéctica marxista y establece un análisis riguroso que determina su carácter no científico. Aunque lo anterior se puede sostener plausiblemente y puede contar con un consenso entre los filósofos especializados, todavía algunos creen en el supuesto carácter científico de la dialéctica, de sus principios, categorías y leyes. Asimismo, aún persiste la creencia en la existencia de una supuesta lógica dialéctica y método dialéctico, lo que cabe entender como un mero autoengaño. En este trabajo, se demostrará que tal creencia es insostenible y se apoya en una comprensión superficial de la ciencia. En efecto, aquí se demostrará que la dialéctica no es ciencia, que la lógica dialéctica no existe y que el llamado método dialéctico no puede considerarse como un método científico.

    Winder, C; Turner, P J

    1992-08-01

    As part of a multidisciplinary study into the health effects of solvents, workplace assessments and airborne solvent vapour monitoring was conducted in 46 spray painting workshops in the Sydney metropolitan area. Breathing-zone samples were taken from 50 apprentices and 14 experienced spray painters. An interview schedule was developed to obtain information about the use of acrylic or two-pack paint systems, the use of engineering controls, the use of personal protective equipment and the availability of material safety data sheets. Contaminants typical of the chemical products used in this industry were encountered (aromatic hydrocarbons, C5-C7 aliphatic hydrocarbons, ketones, esters). The results of airborne solvent monitoring indicate a total solvent exposure in the range 1-99% of a combined Worksafe Australia exposure standard, with a mean of 19%. Solvent exposure was highest when spraying acrylic paint in the open workshop and lowest when spraying two pack paint in a spray booth. Much the same personal protective equipment was available in all workshops, but wide variation in its use was observed. Material safety data sheets were not observed in any of the workshops.

    Directory of Open Access Journals (Sweden)

    Guoliang Lin

    Full Text Available VennPainter is a program for depicting unique and shared sets of genes lists and generating Venn diagrams, by using the Qt C++ framework. The software produces Classic Venn, Edwards' Venn and Nested Venn diagrams and allows for eight sets in a graph mode and 31 sets in data processing mode only. In comparison, previous programs produce Classic Venn and Edwards' Venn diagrams and allow for a maximum of six sets. The software incorporates user-friendly features and works in Windows, Linux and Mac OS. Its graphical interface does not require a user to have programing skills. Users can modify diagram content for up to eight datasets because of the Scalable Vector Graphics output. VennPainter can provide output results in vertical, horizontal and matrix formats, which facilitates sharing datasets as required for further identification of candidate genes. Users can obtain gene lists from shared sets by clicking the numbers on the diagram. Thus, VennPainter is an easy-to-use, highly efficient, cross-platform and powerful program that provides a more comprehensive tool for identifying candidate genes and visualizing the relationships among genes or gene families in comparative analysis.

    Survival times of US women radium dial workers to the end of 1989 were examined by life table methods. Included were 1301 women rust employed before 1930 and 1242 first employed in 1930-1949. Expected numbers of deaths were estimated from age- and time-specific death rates for US white females. In the early group, 85 deaths from the well-known radium-induced cancers - bone sarcomas and head carcinomas - were observed, but only 724 deaths from aH other causes were observed vs 755 expected. Life shortening (±S.E.) of 1.8 ±0.5 y compared to the general population of US white females was calculated from the time distribution of all deaths in the pre-1930 group. In the 1930--1949 group, 350 deaths were observed vs 343 expected and no bone sarcomas or head carcinomas occurred. Among women who survived at least 2 y after rust measurement of body radium, a significant excess of observed vs expected deaths was found only for radium intakes greater than 1.85 MBq of 226 Ra + 228 Ra, and no trend of deaths or reduction of life expectancy was found with length of employment

    2017-11-01

    There are more or less well established technologies such as the optical-parametric-oscillator (OPO), the Raman-laser, and the Ti-Sapphire laser, which are able to emit laser light in the region of the water vapour absorption lines. For WALES the regions of about 935 nm, 942 nm, and 944 nm have been identified as the most suitable wavelength ranges. However, each of these laser designs is highly sophisticated. Current baseline for WALES is the Ti-Sapphire laser. A fourth possibility to achieve these wavelength ranges is to shift the groundstate laser lines (938 nm and 946 nm) of the Nd:YAG laser by replacing Aluminium and Yttrium by other rare earth elements. Changes of the host lattice characteristics lead to a shift of the upper and lower laser levels. These modified crystals are summarized under the name of "Mixed Garnet" crystals. Only the Mixed Garnet lasers can be pumped directly with diode laser and use a direct approach to generate the required laser pulses without frequency conversion. Therefore no additional non-linear crystals are needed and a higher electric to optical efficiency is expected as well as single frequency operation using spectral tuning elements like etalons. Such lasers have the great potential to fulfil the requirements and to become the preferred transmitter concept for WALES as well as for follow up missions. Within a ESA study several crystal compositions have been grown, spectrally characterised and analysed. Absorbed space radiation energy in the crystal lattice causes colour centres, which can reabsorb the pump and laser wavelength and consequently reduce the laser gain considerably. Co-dopants such as Chromium and Cerium are able to suppress the colour centres and are candidates for effective radiation hardening. The results of the crystal tuning, the co-doping with different radiation hardeners and the radiation tests will be presented. There applicability for a space based water vapour DIAL transmitter will be discussed.

Another problem related to data curation and interoperability is the possibility to use common vocabularies. Common vocabularies are developed in many international initiatives, such as GEMET (promoted by INSPIRE as a multilingual thesaurus), UNIDATA, SeaDataNet, Marine Metadata Initiative (MMI). MIS is considering the SeaDataNet vocabulary as a base for interoperability. Four layers of different abstraction levels of interoperability an be defined: - Technical/basic: this layer is implemented at each TAC or MFC through internet connection and basic services for data transfer and browsing (e.g FTP, HTTP, etc). - Syntactic: allowing the interchange of metadata and protocol elements. This layer corresponds to a definition Core Metadata Set, the format of exchange/delivery for the data and associated metadata and possible software. This layer is implemented by the DIAL-P logical interface (e.g. adoption of INSPIRE compliant metadata set and common data formats). - Functional/pragmatic: based on a common set of functional primitives or on a common set of service definitions. This layer refers to the definition of services based on Web services standards. This layer is implemented by the DIAL-P logical interface (e.g. adoption of INSPIRE compliant network services). - Semantic: allowing to access similar classes of objects and services across multiple sites, with multilinguality of content as one specific aspect. This layer corresponds to MIS interface, terminology and thesaurus. Given the above requirements, the proposed solution is a federation of systems, where the individual participants are self-contained autonomous systems, but together form a consistent wider picture. A mid-tier integration layer mediates between existing systems, adapting their data and service model schema to the MIS. The developed MIS is a read-only system, i.e. does not allow

    2013-12-01

    Full Text Available A 46-year-old man who had worked as a bumper spray painter in an automobile body shop for 15 years developed lung cancer. The patient was a nonsmoker with no family history of lung cancer. To determine whether the cancer was related to his work environment, we assessed the level of exposure to carcinogens during spray painting, sanding, and heat treatment. The results showed that spray painting with yellow paint increased the concentration of hexavalent chromium in the air to as much as 118.33 μg/m3. Analysis of the paint bulk materials showed that hexavalent chromium was mostly found in the form of lead chromate. Interestingly, strontium chromate was also detected, and the concentration of strontium chromate increased in line with the brightness of the yellow color. Some paints contained about 1% crystalline silica in the form of quartz.

    A DIAL instrument on a moving platform is seen as a valuable remote sensing component in a sensor network for area monitoring, targeting sites involved in unauthorised explosive manufacturing. Such instrument will perform the area mapping of the vapour concentration of key substances, known to be used as precursors in explosive fabrication, such as acetone and nitromethane. The IR spectra of acetone and nitromethane vapours have been defined from available spectroscopy databases and from laboratory measurements as showing optimal spectral band for the DIAL operation in the spectral range of 3.0 μm - 3.5 μm. The DIAL operation has been numerically simulated, with inputs based on the HITRAN database, the U.S. Standard Atmosphere and aerosol simulation software package OPAC. A combination of OPO and OPA has been chosen as a transmitter, where the idler wavelength is used for probing, with wavelength tuning in sequence. A scanner mounted on top of the coaxially aligned laser and receiver, is capable of covering almost 360 degrees horizontally and +/-30 degrees vertically. The detection is performed by a photovoltaic photodiode with 4-stage cooling, with a signal digitalisation having 14 bit amplitude resolution and 125 Ms/s sampling rate. Here we present the development and the first test of the DIAL instrument.

    Forty-five sealed glass ampoules containing samples of radium dial paint prepared by the US Radium Corporation (USRC) and used by New Jersey dial workers in the period 1915--1928, were analyzed for radium-226 and radium-228 activity by high-resolution gamma-ray spectrometry. Radium-228 was found to be the dominant activating agent at the probable time of use in most of the sampled paints in which the ratio of radium-228 to radium-226 activity was determinable, the calculated radium-228 to radium-226 activity ratio in 1920 in these ranging from 7.2 to 10 (median 8.4), indicating that radium element chemically separated from commercialthorium ores (technical mesothorium) was used as the activator. Published isotopic activity ratios in USRC dial-paint samples that were appreciably in excess of those we found are shown invariably to be due to errors in calculation. Our results and information in the early literature suggested the hypothesis that dial paints used at USRC before July 1919 were activated with isotopically pure radium-226 whereas compounds used thereafter until the year 1925 were activated with technical mesothorium- Isotopic activity ratios predicted by the hypothesis compared well with median ratios observed in two groups of former workers. We conclude that inaccuracies in dates of hire and termination at USRC might well be the principal source of uncertainty in estimates of skeletal dose for former workers in whom the isotopic activity ratio has not been measured

    Full Text Available Tunja has stood out as one of the riches cities of New Kingdom of Granada, regarding the presence of painting in the last decades of the XVI century and the first half of the XVIIth. Its painters were of importance not only in this city but in the rest of the Province as well, with the churches and museums of Boyacá containing images that were essential elements in the indoctrination of indigenous communities. Civil mural works of art in Tunja have been an object of study mostly for their interpretation, and less regarding the identities of their makers. As far as easel painting, Angelino Medoro eclipsed the names of other artists who contributed to making Tunja one the the most representative cities of the Mannerism and Renaissance of Hispanic America. This article presents the names of some of the active painters of this period, their lives and production, seeking the recognition of these characters, whose names have been brought out of anonymity in the latest years. The starting point for the information search was the research of Magdalena Corradine Mora on the inhabitants of Tunja in the first decades of the XVII century, and the search for information in the Boyacá Regional Historical Archive. In calling attention upon these artists, we hope that, in the future, the identification of their works may be initiated as well as the research, conservation and dissemination of these works, due to the fact that this heritage is not always in ideal conditions, nor is it perceived and valued as is deserved.

    The relationships of radium exposure to mortality from multiple myeloma, leukemia, and breast cancer were studied in three cohorts of female dial workers defined by year of first employment. A three-fold excess risk of multiple myeloma occurred in the pre-1930 cohort; however, analyses of body burdens and durations of employment suggest that external radiation was more likely to have been responsible than was internal radium. Leukemia incidence and mortality have not been elevated overall among the female dial workers, either in the pre-1930 or the post-1930 cohorts, but cases have tended to occur early and in subjects with higher body burdens of radium. Extensive analyses of breast cancer data have uncovered several observations weighing against a causal interpretation of the association between radium body burdens and breast cancer

    Recently, we successfully demonstrated a new compact and robust ozone DIAL lidar for smaller aircraft such as the NASA B200 and the ER-2 high-altitude aircraft. This is the first NASA airborne lidar to incorporate advanced solid-state lasers to produce the required power at the required ultraviolet wavelengths, and is compact and robust enough to operate nearly autonomously on the high-altitude ER-2 aircraft. This technology development resulted in the first new NASA airborne ozone DIAL instrument in more than 15 years. The combined ozone, aerosol, and clouds measurements provide valuable information on the chemistry, radiation, and dynamics of the atmosphere. In particular, from the ER-2 it offers a unique capability to study the upper troposphere and lower stratosphere.

    Full Text Available Due to static traffic assignment has poor performance in reflecting actual case and dynamic traffic assignment may incurs excessive compute cost, method of multi-time dynamic traffic assignment combining static and dynamic traffic assignment balances factors of precision and cost effectively. A method based on Dial's logit algorithm is proposed in the article to solve the dynamic stochastic user equilibrium problem in dynamic traffic assignment. Before that, a fitting function that can proximately reflect overloaded traffic condition of link is proposed and used to give corresponding model. Numerical example is given to illustrate heuristic procedure of method and to compare results with one of same example solved by other literature's algorithm. Results show that method based on Dial's algorithm is preferable to algorithm from others.

    We are in the process of evaluating the performance of an eye-safe, low-cost, diode-laser-based, water vapor differential absorption lidar (DIAL) profiler. This class of instrument may be capable of providing continuous water vapor and aerosol backscatter profiles at high vertical resolution in the atmospheric boundary layer (ABL) for periods of months to years. The technology potentially fills a national long term observing facility gap and could greatly benefit micro- and meso-meteorology, water cycle, carbon cycle and, more generally, biosphere-hydrosphere-atmosphere interaction research at both weather and climate variability time scales. For the evaluation, the Montana State University 3rd generation water vapor DIAL was modified to enable unattended operation for a period of several weeks. The performance of this V3.5 version DIAL was tested at MSU and NCAR in June and July of 2012. Further tests are currently in progress with Howard University at Beltsville, Maryland; and with the National Weather Service and Oklahoma University at Dallas/Fort Worth, Texas. The presentation will include a comparison of DIAL profiles against meteorological "truth" at the aforementioned locations including: radiosondes, Raman lidars, microwave and IR radiometers, AERONET and SUOMINET systems. Instrument reliability, uncertainty, systematic biases, detection height statistics, and environmental complications will be evaluated. Performance will be judged in the context of diverse scientific applications that range from operational weather prediction and seasonal climate variability, to more demanding climate system process studies at the land-canopy-ABL interface. Estimating the extent to which such research and operational applications can be satisfied with a low cost autonomous network of similar instruments is our principal objective.

    Recently surveying large areas in an automatic way, for early detection of harmful chemical agents, has become a strategic objective of defence and public health organisations. The Lidar-Dial techniques are widely recognized as a cost-effective alternative to monitor large portions of the atmosphere but, up to now, they have been mainly deployed as ground based stations. The design reported in this paper concerns the development of a Lidar-Dial system compact enough to be carried by a small airplane and capable of detecting sudden releases in air of harmful and/or polluting substances. The proposed approach consists of continuous monitoring of the area under surveillance with a Lidar type measurement. Once a significant increase in the density of backscattering substances is revealed, it is intended to switch to the Dial technique to identify the released chemicals and to determine its concentration. In this paper, the design of the proposed system is described and the simulations carried out to determine its performances are reported. For the Lidar measurements, commercially available Nd- YAG laser sources have already been tested and their performances, in combination with avalanche photodiodes, have been experimentally verified to meet the required specifications. With regard to the DIAL measurements, new compact CO2 laser sources are being investigated. The most promising candidate presents an energy per pulse of about 50 mJ typical, sufficient for a range of at least 500m. The laser also provides the so called "agile tuning" option that allows to quickly tune the wavelength. To guarantee continuous, automatic surveying of large areas, innovative solutions are required for the data acquisition, self monitoring of the system and data analysis. The results of the design, the simulations and some preliminary tests illustrate the potential of the chosen, integrated approach.

    In adults, the motor plans for object-directed grasping movements reflects the anticipated requirements of intended future object manipulations. This prospective mode of planning has been termed second-order planning. Surprisingly, second-order planning is thought to be fully developed only by 10 years of age, when children master seemingly more complex motor skills. In this study, we tested the hypothesis that already 5- and 6-year-old children consistently use second-order planning but that this ability does not become apparent in tasks that are traditionally used to probe it. We asked 5- and 6-year-olds and adults to grasp and rotate a circular dial in a clockwise or counterclockwise direction. Although children's grasp selections were less consistent on an intra- and inter-individual level than adults' grasp selections, all children adjusted their grasps to the upcoming dial rotations. By contrast, in an also administered bar rotation task, only a subset of children adjusted their grasps to different bar rotations, thereby replicating previous results. The results indicate that 5- and 6-year-olds consistently use second-order planning in a dial rotation task, although this ability does not become apparent in bar rotation tasks.

    Full Text Available Considerar a atividade pedagógica como unidade dialética requer que sejam investigadas as condições e circunstâncias que tornam possível tal objetivação e as especificidades da mesma a partir do materialismo histórico dialético, da psicologia histórico-cultural e da teoria da atividade. Concebe-se que a correspondência entre motivos/necessidades, objetivos, ações e operações nas atividades principais dos estudantes e dos educadores cria situações favoráveis para que ocorra a aprendizagem consciente. Tal fato é dependente da consciência da função ontológica do educador e do estudante como sujeitos ativos no processo de ensino-aprendizagem. Considera-se ser possível conceber a unidade dialética desde que a mesma represente uma das condições para a superação das características do sistema educacional vigente, por caracterizar-se a atividade material do homem como a que transforma o mundo material e social em mundo humano.

    Full Text Available OBJECTIVES: Sex differences in occupational biomechanical exposures may be part of the explanation why musculoskeletal complaints and disorders tend to be more common among women than among men. We aimed to determine possible sex differences in task distribution and task-specific postures and movements of the upper extremities among Danish house painters, and to establish sex-specific task exposure matrices. METHODS: To obtain task distributions, we sent out a questionnaire to all members of the Painters' Union in Denmark (N = 9364, of whom 53% responded. Respondents reported their task distributions in a typical week. To obtain task exposures, postures and movements were measured in 25 male and 25 female house painters for one whole working day per person. We used goniometers on the wrists, and inclinometers on the forehead and the upper arms. Participants filled in a logbook allowing task-specific exposures to be identified. Percentiles and % time with non-neutral postures were used to characterise postures. Velocity, range of motion, repetitiveness, and variation were used as measures of movement. Cochran-Mantel-Haenszel statistics and unpaired double-sided t-tests with post-hoc Bonferroni correction were used to evaluate sex differences. RESULTS: Statistically significant (p<0.05 sex differences were revealed in task proportions, but the proportions differed by less than 4%. For task exposures, no statistically significant sex differences were found. CONCLUSIONS: Only minor sex differences were found in task distribution and task exposures regarding postures and movements among Danish house painters. Sex-specific task exposure matrices were established.

    Rapid expansion of the oil and gas industry in Alberta, including the oil sands, has challenged the Alberta Government to keep pace in its efforts to monitor and mitigate the environmental impacts of development. The limitations of current monitoring systems has pushed the provincial government to seek out advanced sensing technologies such as satellite imagery and laser based sensors. The Space Dynamics Laboratory (SDL) of Utah State University, in cooperation with Alberta Environmental Monitoring, Evaluation and Reporting Agency (AEMERA), has developed North America's first mobile differential absorption lidar (DIAL) system designed specifically for emissions measurement. This instrument is housed inside a 36' trailer which allows for mobility to travel across Alberta to characterize source emissions and to locate fugitive leaks. DIAL is capable of measuring concentrations for carbon dioxide (CO2) and methane (CH4) at ranges of up to 3 km with a spatial resolution of 10 meters. DIAL can map both CO2 and CH4, as well as particulate matter (PM) in a linear fashion; by scanning the laser beam in both azimuth and elevation DIAL can create images of emissions in two dimensions. DIAL imagery may be used to understand and control production practices, characterize source emissions, determine emission factors, locate fugitive leaks, assess plume dispersion, and confirm air dispersion modeling. A system overview of the DIAL instrument and some representative results will be discussed.

    Full Text Available Among the numerous travelogues describing southern Dalmatia, Dubrovnik, and its surroundings, the booklet called Lacroma merits special attention. Its author was the widowed Crown Princess Stephanie (1864-1945 and the illustrations were provided by Anton Perko, seascape painter at the court and the former governor of Lokrum. The first edition was published in 1892 in German, followed by an Italian one five years later. This article focuses on the first, German edition. Painter Anton Perko (1833-1905 stayed on the island of Lokrum from January 1879 until the beginning of 1881, with minor absences. The following year, he spent the entire winter on the island, and when the princely couple moved to Vienna, he also moved there in 1883. After the Mayerling drama, when Rudolf and his young mistress Marie Vetsera were found dead under mysterious circumstances, Perko’s life changed as well, yet he remained in the service of the widowed princess until 1896, when he retired. Anton Perko did not write an autobiography, but his important position in the royal household is evident from the fact that Stephanie and her daughter took care of his widow after his death in 1905. In 1892, a volume on Dalmatia was published as part of the complex work Die österreichisch-ungarische Monarchie in Wort und Bild, initiated by Prince Rudolf and continued by his widow Stephanie, which must have also inspired her to write a separate book on Lokrum with its rich historical, cultural, and natural heritage. Her description of Lokrum is intended for future tourists, potential visitors from the north, and introduces the reader to this insular Arcadia with descriptions of its position in southern Dalmatia and Dubrovnik, after which she turns to the history of Lokrum and its monuments, with reference to two written sources: the Apendius chronicle and the Memorie storiche sull’isola Lacroma, published in Vienna in 1861. Illustrations by Anton Perko are completely subjected to

    To assess the association between the use of personal protective equipment (PPE) and good workplace hygiene and symptoms of neurotoxicity in solvent-exposed vehicle spray painters. Exposure control measures including PPE-use and workplace hygiene practices and symptoms of neurotoxicity were assessed in 267 vehicle repair spray painters. Symptoms were assessed using an adapted version of the EUROQUEST Questionnaire. Frequent respirator and glove use was inversely and significantly associated with symptoms of neurotoxicity in a dose-dependent manner (P 80%. Poor hygiene workplace practices, such as solvent exposure to multiple body parts (OR 3.4, P = 0.11 for reporting ≥10 symptoms), were associated with an increased risk of symptoms. When using a general workplace hygiene score derived from a combination of PPE-use and (good) workplace practice factors an inverse and significant dose-response trend was observed for reporting ≥5 (P hygiene are associated with a strongly reduced risk of symptoms of neurotoxicity in solvent-exposed vehicle spray painters.

    A method for subsurface recognition of blind geological bodies is presented using combined surface constraints and 3-D structural modelling that incorporates constraints from detailed mapping, and potential-field inversion modelling. This method is applied to the Mount Painter Province and demonstrates that addition of low density material is required to reconcile the gravity signature of the region. This method may be an effective way to construct 3-D models in regions of excellent structural control, and can be used to assess the validity of surface structures with 3-D architecture. Combined geological and potential-field constrained inversion modelling of the Mount Painter Province was conducted to assess the validity of the geological models of the region. Magnetic susceptibility constrained stochastic property inversions indicates that the northeast to southwest structural trend of the relatively magnetic meta-sedimentary rocks of the Radium Creek Group in the Mount Painter Inlier is reconcilable with the similar, northeast to southwest trending positive magnetic anomalies in the region. Radium Creek Group packages are the major contributor of the total magnetic response of the region. However field mapping and the results of initial density constrained stochastic property inversion modelling do not correlate with a large residual negative gravity anomaly central to the region. Further density constrained inversion modelling indicates that an additional large body of relatively low density material is needed within the model space to account for this negative density anomaly. Through sensitivity analysis of multiple geometrical and varied potential-field property inversions, the best-fitting model records a reduction in gravity rms misfit from 21.9 to 1.69 mGal, representing a reduction from 56 to 4.5 per cent in respect to the total dynamic range of 37.5 mGal of the residual anomaly. This best-fitting model incorporates a volumetrically significant source

    The improvement of computer hardware and software of the NASA Multipurpose Differential Absorption Lidar (DIAL) system is documented. The NASA DIAL system has undergone development and experimental deployment at NASA/Langley Res. Center for the remote measurement of atmospheric trace gas concentrations from ground and aircraft platforms. A viable DIAL system was developed capable of remotely measuring O3 and H2O concentrations from an aircraft platform. The DIAL Data Acquisition System (DAS) has undergone a number of improvements also. Due to the participation of the DIAL in the Global Tropospheric Experiment, modifications and improvements of the system were tested and used both in the lab and in air. Therefore, this is an operational manual for the DIAL DAS.

    Among the female radiation workers in the radium dial industry there is no overall excess of brain or central nervous system tumors. A significant excess did appear, however, in one of three major cohorts; the excess was not due to an excess of gliomas and cannot be ascribed with certainty to radium or external radiation. A significant proportional excess of tumors outside the brain was observed, and is consistent with irradiation of nervous system tissue from adjacent bone. Early deaths from brain abscess or mastoiditis, which are coded as diseases of the nervous system and sense organs, were observed. 12 refs., 11 tabs

    The production of radium paint has been stopped in Switzerland nearly 40 years ago. Nevertheless high quantities of dials and hands with radium paint could be found in the stocks of watch companies. In addition these parts of watches were thrown away illegally as scrap metal or as rubbish. As a consequence the Swiss National Accident Insurance Fund (Suva) has organized a collecting campaign in collaboration with the Federal Office of Public Health (BAG). It was the fourth one during the last 20 years. The procedure and the experiences will be described in more details. (orig.)

    Female radium dial workers first employed before 1930 were analyzed for breast cancer mortality and incidence using method and rate tables described by Monson and the Mantel-Haenszel summary chi-square test for significance. Of 1180 located women, 736 were measured to estimate radium intake. This measured group was analyzed for breast cancer mortality and incidence according to four possible risk factors: radium intake dose, duration of employment, age at first exposure, and parity. The measured women showed a significant excess of breast cancer incidence and mortality only among those women with a radium intake of 50 μCi or greater

    A Brain-computer interface (BCI) is a novel communication system that translates brain signals into a control signal. Now with the appearance of the commercial EEG headsets and mobile smart platforms (tablet, smartphone), it is possible to develop the mobile BCI system, which can greatly improve the life quality of patients suffering from motor disease, such as amyotrophic lateral scleroses (ALS), multiple sclerosis, cerebral palsy and head trauma. This study adopted a 14-channel Emotiv EPOC headset and Microsoft surface pro 3 to realize a dialing system, which was represented by 4×3 matrices of alphanumeric characters. The performance of the online portable dialing system based on P300 is satisfying. The average classification accuracy reaches 88.75±10.57% in lab and 73.75±16.94% in metro, while the information transfer rate (ITR) reaches 7.17±1.80 and 5.05±2.17 bits/min respectively. This means the commercial EEG headset and tablet has good prospect in developing real time BCI system in realistic environments.

    It's well known that air pollution due to anthropogenic sources can have adverse effects on humans and the ecosystem. Therefore, in the last years, surveying large regions of the atmosphere in an automatic way has become a strategic objective of various public health organizations for early detection of pollutant sources in urban and industrial areas.The Lidar and Dial techniques have become well established laser based methods for the remote sensing of the atmosphere. They are often implemented to probe almost any level of the atmosphere and to acquire information to validate theoretical models about different topics of atmospheric physics. They can also be used for environment surveying by monitoring particles, aerosols and molecules.The aim of the present work is to demonstrate the potential of these methods to detect pollutants emitted from local sources (such as particulate and/or chemical compounds) and to evaluate their concentration. This is exemplified with the help of experimental data acquired in an industrial area in the south of Italy by mean of experimental campaign by use of pollutants simulated source. For this purpose, two mobile systems Lidar and Dial have been developed by the authors. In this paper there will be presented the operating principles of the system and the results of the experimental campaign. (paper)

  1. Interpretation of DIAL Measurements of Lower Stratospheric Ozone in Regions with Pinatubo Aerosols

    The influence of volcanic aerosols on stratospheric ozone is a topic of current interest, especially with the June 15, 1991 eruption of Mt. Pinatubo in the Philippines. Lidar has been used in the past to provide aerosol profiles which could be compared with ozone profiles measured using ozonesondes to look for coincidences between volcanic aerosols and ozone decreases. The differential absorption lidar (DIAL) technique has the advantages of being able to measure ozone and aerosol profiles simultaneously as well as being able to cover large geographical regions rapidly. While there are problems associated with correcting the ozone profiles for the presence of aerosols, the corrections can be made reliably when the wavelengths are closely spaced and the Bernoulli method is applied. The DIAL measurements considered in this paper are those obtained in the tropical stratosphere in January 1992 during the Airborne Arctic Stratospheric Expedition (AASE-II). The determination of ozone profiles in the presence of Pinatubo aerosols is discussed in a companion paper.

  2. Dose-response relationships for female radium dial workers: A new look

    Rowland, R.E.

    1994-01-01

    The values of initial systemic intake and of skeletal dose for all of the U.S. radium cases have recently been revised. This revision was required following the demonstrations by Rundo and by Keane that humans who were exposed to radium as adults lost radium at a rate that depended on the quantity of radium originally deposited within their bodies. These new values have been used to define new dose-response relationships for both the bone sarcomas and the carcinomas arising in the paranasal sinuses and mastoid air cells induced by internally deposited radium. The population examined was employed in the U.S. dial painting industry prior to 1950 and consisted of 1530 female dial workers for whom radium body burden measurements were available. By the end of 1990, 46 cases of bone sarcomas and 19 cases of head carcinomas had been diagnosed in this cohort. The head carcinoma incidence can be adequately fitted by a simple linear function, as was found in previous analyses. The bone sarcoma cases were previously fitted by a dose-squared-exponential function. With the revised values of systemic intake, the sarcoma results could not be satisfactorily fitted with this expression. When the exponent on D was increased to larger values, excellent fits were obtained

    1983-01-01

    The relationships of radium exposure to mortality from multiple myeloma, leukemia, and breast cancer were studied in three cohorts of female dial workers defined by year of first employment. Mortality was compared with that expected from US white female rates, with and without adjustment for local mortality rates. Dose-response relationships of these cancers to systemic intake of radium were determined in workers whose body burdens had been measured in vivo since 1955. Incident cases of multiple myeloma occurred in the pre-1930 cohort; however, analyses of body burdens and durations of employment suggest that external radiation was more likely to have been responsible than was internal radium. Leukemia incidence and mortality have not been elevated overall among the female dial workers, either in the pre-1930 or the post-1930 cohorts, but cases have tended to occur early and in subjects with higher body burdens. Extensive analyses of breast cancer data have uncovered several observations weighing against a causal interpretation of the association between radium and breast cancer

    To study inhalation and dermal exposure to hexamethylene diisocyanate (HDI) and its oligomers as well as personal protection equipment (PPE) use during task performance in conjunction with urinary hexamethylene diamine (HDA) in car body repair shop workers and industrial spray painters. Personal task based inhalation samples (n = 95) were collected from six car body repair shops and five industrial painting companies using impingers with di-n-butylamine (DBA) in toluene. In parallel, dermal exposure was assessed using nitril rubber gloves. Gloves were submerged into DBA in toluene after sampling. Analysis for HDI and its oligomers was performed by LC-MS/MS. Urine samples were collected from 55 workers (n = 291) and analysed for HDA by GC-MS. Inhalation exposure was strongly associated with tasks during which aerosolisation occurs. Dermal exposure occurred during tasks that involve direct handling of paint. In car body repair shops associations were found between detectable dermal exposure and glove use (odds ratio (OR) 0.22, 95% confidence interval (CI) 0.09 to 0.57) and inhalation exposure level (OR 1.34, 95% CI 0.97 to 1.84 for a 10-fold increase). HDA in urine could be demonstrated in 36% and 10% of car body repair shop workers and industrial painting company workers respectively. In car body repair shops, the frequency of detectable HDA was significantly elevated at the end of the working day (OR 2.13, 95% CI 1.07 to 4.22 for 3-6 pm v 0-8 am). In both branches HDA was detected in urine of approximately 25% of the spray painters. In addition HDA was detected in urine of a large proportion of non-spray painters in car body repair shops. Although (spray) painting with lacquers containing isocyanate hardeners results in the highest external exposures to HDI and oligomers, workers that do not perform paint related tasks may also receive a considerable internal dose.

    Differential Absorption Lidar (DIAL) using solid state Ti:sapphire lasers finds current application in the NASA/LASE Project for H2O vapor measurements in the approximately = 0.820 micron region for the lower and mid-troposphere and in potential future applications in planned measurements of the approximately = 0.940 micron region where both strong and weak absorption lines enables measurements throughout the troposphere and lower stratosphere. The challenge exists to perform measurements in the eye-safe greater than 1.5 micron region. A comparison between DIAL and passive Gas Filter Correlation Radiometer (GFCR) measurements is made. The essence of the differences in signal to noise ratio for DIAL and passive GFCR measurements is examined. The state of the art of lasers and optical parametric oscillators (OPO's) is discussed.

    Female radium dial workers first employed before 1930 were analyzed for breast cancer mortality and incidence using method and rate tables described by Manson and the Mantel-Haenszel summary chi-square test for significance. Of 1180 located women, 736 were measured to estimate radium intake. This measured group was analyzed for breast cancer mortality and incidence according to four possible risk factors: radium intake dose, duration of employment, age at first exposure, and parity. The located women had a mortality ratio of 1.51 (p < 0.05). The measured women showed a significant excess of breast cancer incidence and mortality only among those women with a radium intake of 50 μCi or greater. Although not significant, incidence and mortality ratios were slightly higher for nulliparous women

  10. Solving the dial-a-ride problem using agent-based simulation

    Directory of Open Access Journals (Sweden)

    Campbell, Ian

    2016-11-01

    Full Text Available The ‘dial-a-ride problem’ (DARP requires a set of customers to be transported by a limited fleet of vehicles between unique origins and destinations under several service constraints, including within defined time windows. The problem is considered NP-hard, and has typically been solved using metaheuristic methods. An agent-based simulation (ABS model was developed, where each vehicle bids to service customers based on a weighted objective function that considers the cost to service the customer and the time quality of the service that would be achieved. The approach applied a pre- processing technique to reduce the search space, given the service time window constraints. Tests of the model showed significantly better customer transit and waiting times than the benchmark datasets. The ABS was able to obtain solutions for much larger problem sizes than the benchmark solutions, with this work being the first known application of ABS to the DARP.

    A new unpiloted air vehicle (UAV) based water vapor DIAL system will be described. This system is expected to offer lower operating costs, longer test duration and severe weather capabilities. A new high-efficiency, compact, light weight, diode-pumped, tunable Cr:LiSAF laser will be developed to meet the UAV payload weight and size limitations and its constraints in cooling capacity, physical size and payload. Similarly, a new receiver system using a single mirror telescope and an avalanche photo diode (APD) will be developed. Projected UAV parameters are expected to allow operation at altitudes up to 20 km, endurance of 24 hrs and speed of 400 km/hr. At these conditions measurements of water vapor at an uncertainty of 2-10% with a vertical resolution of 200 m and horizontal resolution of 10 km will be possible.

    The mobile light detection and ranging DIAL system of Malek Ashtar University of Technology has been developed for the detection of chemical warfare agents whose absorption wavelengths are in the range of 9.2–10.8 μm tunable CO 2 lasers of the system. In this paper, this system is first described and then ammonia detection is analyzed experimentally. Also, experimental results of detecting a sarin agent simulant, dimethyl–methyl phosphonate (DMMP), are presented. The power levels received from different ranges to detect specific concentrations of NH 3 and DMMP have been measured and debated. The primary test results with a 150 ns clipped pulse width by passive pinhole plasma shutter indicate that the system is capable of monitoring several species of pollutants in the range of about 1 km, with a 20 m spatial and 2 min temporal resolution.

    2017-07-03

    Suicide is an important public health concern requiring ongoing research to understand risk factors for suicide ideation. A dual-frame, random digit dial survey was utilized to identify demographic and suicide-related factors associated with suicide ideation in a statewide sample of 1,736 adults. The PH-Q 9 Depression scale suicide ideation question was used to assess current suicide ideation in both the full sample and suicide exposed sub-sample. Being non-married and having previous suicide exposure were separately associated with higher risks of suicide ideation in the full sample. Being male, having increased suicide exposures, and having increased perceptions of closeness to the decedent increased risks, while older age decreased risks for the suicide exposed. Implications for future screening and research are discussed.

    Full Text Available Using a cross-sectional descriptive study design, surveys were mailed to 200 randomly selected certified hand therapists of the American Society of Hand Therapists (ASHT to determine how they document analog dynamometer and pinch gauge dial readings. Three different needle settings for the dynamometer and pinch gauge were presented in picture format. For each instrument, one needle setting was just above a gauge marker, one was just below a gauge marker, and one was set exactly between two gauge markers. A total of 126out of 200 surveys were returned for a participation rate of 63%. For the dynamometer readings, therapists estimated the exact strength reading between the two gauge markers 78.3% of the time. For the pinch gauge readings, therapists rounded to the nearest dial marker 76.5% of the time when the needle was just above or just below a dial marker and 61.9% of the time they estimated the reading when the needle was placed exactly between two dial markers.

    2011-12-01

    The problem of transporting patients or elderly people has been widely studied in literature and is usually modeled as a dial-a-ride problem (DARP). In this paper we analyze the corresponding problem arising in the daily operation of the Austrian Red Cross. This nongovernmental organization is the largest organization performing patient transportation in Austria. The aim is to design vehicle routes to serve partially dynamic transportation requests using a fixed vehicle fleet. Each request requires transportation from a patient's home location to a hospital (outbound request) or back home from the hospital (inbound request). Some of these requests are known in advance. Some requests are dynamic in the sense that they appear during the day without any prior information. Finally, some inbound requests are stochastic. More precisely, with a certain probability each outbound request causes a corresponding inbound request on the same day. Some stochastic information about these return transports is available from historical data. The purpose of this study is to investigate, whether using this information in designing the routes has a significant positive effect on the solution quality. The problem is modeled as a dynamic stochastic dial-a-ride problem with expected return transports. We propose four different modifications of metaheuristic solution approaches for this problem. In detail, we test dynamic versions of variable neighborhood search (VNS) and stochastic VNS (S-VNS) as well as modified versions of the multiple plan approach (MPA) and the multiple scenario approach (MSA). Tests are performed using 12 sets of test instances based on a real road network. Various demand scenarios are generated based on the available real data. Results show that using the stochastic information on return transports leads to average improvements of around 15%. Moreover, improvements of up to 41% can be achieved for some test instances.

    Objectives To study inhalation and dermal exposure to hexamethylene diisocyanate (HDI) and its oligomers as well as personal protection equipment (PPE) use during task performance in conjunction with urinary hexamethylene diamine (HDA) in car body repair shop workers and industrial spray painters. Methods Personal task based inhalation samples (n = 95) were collected from six car body repair shops and five industrial painting companies using impingers with di‐n‐butylamine (DBA) in toluene. In parallel, dermal exposure was assessed using nitril rubber gloves. Gloves were submerged into DBA in toluene after sampling. Analysis for HDI and its oligomers was performed by LC‐MS/MS. Urine samples were collected from 55 workers (n = 291) and analysed for HDA by GC‐MS. Results Inhalation exposure was strongly associated with tasks during which aerosolisation occurs. Dermal exposure occurred during tasks that involve direct handling of paint. In car body repair shops associations were found between detectable dermal exposure and glove use (odds ratio (OR) 0.22, 95% confidence interval (CI) 0.09 to 0.57) and inhalation exposure level (OR 1.34, 95% CI 0.97 to 1.84 for a 10‐fold increase). HDA in urine could be demonstrated in 36% and 10% of car body repair shop workers and industrial painting company workers respectively. In car body repair shops, the frequency of detectable HDA was significantly elevated at the end of the working day (OR 2.13, 95% CI 1.07 to 4.22 for 3–6 pm v 0–8 am). In both branches HDA was detected in urine of ∼25% of the spray painters. In addition HDA was detected in urine of a large proportion of non‐spray painters in car body repair shops. Conclusion Although (spray) painting with lacquers containing isocyanate hardeners results in the highest external exposures to HDI and oligomers, workers that do not perform paint related tasks may also receive a considerable internal dose.

    In the framework of CO2 monitoring in the Atmospheric Boundary Layer (ABL), a ground-based 2-μm Differential Absorption Lidar (DIAL) has been developed at the Laboratoire de Météorologie Dynamique (LMD) in Palaiseau. In order to derive flux information, this system has been set up with coherent detection, which allows to combine CO2 density measurements with wind velocity measurements. On the other hand, new advances in the field of Mercury Cadmium Tellure (MCT) Avalanche Photodiodes (APDs) open the way for high-precision measurements in direct detection ultimately from space. In this study, we first report on state of the art measurements obtained with the current coherent DIAL system before presenting expected results for a similar laser transmitter equipped with MCT APDs. For this latter part, we use a numerical model which relies on APDs performance data provided by the Laboratoire d'Électronique et de Technologie de l'Information (LETI).

    In this paper we report, for the first time to our knowledge, on lidar/DIAL detection of acetone vapors at 3.3 μm by means of an optical parametric tunable laser system. After a preliminary spectroscopic study in an absorption cell, the feasibility of a differential absorption (DIAL) lidar for the detection of acetone vapors has been investigated in the laboratory, simulating the experimental conditions of a field campaign. Having in mind measurements in a real scenario, a study of possible atmospheric intereferents has been performed, looking for all known compounds that share acetone IR absorption in the spectral band selected for its detection. Possible interfering species from urban and industrial atmospheres were investigated and limits of acetone detection in both environments were identified. This study confirmed that a lidar system can detect a low concentration of acetone at considerable distances.

    2008-03-01

    Full Text Available Random-digit-dialing surveys in the United States such as the Behavioral Risk Factor Surveillance System (BRFSS typically poststratify on age, gender and race/ethnicity using control totals from an appropriate source such as the 2000 Census, the Current Population Survey, or the American Community Survey. Using logistic regression and interaction detection software we identified key "main effect" socio-demographic variables and important two-factor interactions associated with several health risk factor outcomes measured in the BRFSS, one of the largest annual RDD surveys in the United States. A procedure was developed to construct control totals, which were consistent with estimates of age, gender, and race/ethnicity obtained from a commercial source and distributions of other demographic variables from the Current Population Survey. Raking was used to incorporate main effects and two-factor interaction margins into the weighting of the BRFSS survey data. The resulting risk factor estimates were then compared with those based on the current BRFSS weighting methodology and mean squared error estimates were developed. The research demonstrates that by identifying socio-demographic variables associated with key outcome variables and including these variables in the weighting methodology, nonresponse bias can be substantially reduced.

    Use of random-digit dialing (RDD) for conducting health surveys is increasingly problematic because of declining participation rates and eroding frame coverage. Alternative survey modes and sampling frames may improve response rates and increase the validity of survey estimates. In a 2005 pilot study conducted in six states as part of the Behavioral Risk Factor Surveillance System, the authors administered a mail survey to selected household members sampled from addresses in a US Postal Service database. The authors compared estimates based on data from the completed mail surveys (n = 3,010) with those from the Behavioral Risk Factor Surveillance System telephone surveys (n = 18,780). The mail survey data appeared reasonably complete, and estimates based on data from the two survey modes were largely equivalent. Differences found, such as differences in the estimated prevalences of binge drinking (mail = 20.3%, telephone = 13.1%) or behaviors linked to human immunodeficiency virus transmission (mail = 7.1%, telephone = 4.2%), were consistent with previous research showing that, for questions about sensitive behaviors, self-administered surveys generally produce higher estimates than interviewer-administered surveys. The mail survey also provided access to cell-phone-only households and households without telephones, which cannot be reached by means of standard RDD surveys.

    The results of measurements of radium contents in 13 women made over 20 years or more were used to measure radium retention. The women were all employed at different studios of the same Illinois plant as luminous dial workers for up to 4 years. The data for each woman were fitted to an exponential function of time, yielding a biological half-life of approximately 30 to 60 years. There was a strong negative correlation between elimination rate and body content, suggesting an effect of radiation of bone resorption or remodelling. A strong negative correlation was observed between the elimination rate and the reduced x-ray score, a measure of bone damage observed radiographically in the same subjects. Age at first exposure and duration of exposure were not significantly correlated with the elimination rate. The concentration of radium in soft tissues from eight other subjects, expressed as a percentage of the terminal radium content, decreased with increasing body content, providing further evidence that radiation was affecting the elimination rate. An effect of radiation on the late retention of radium has been demonstrated. 10 references, 4 figures, 2 tables

    Introduction Generating a nationally representative sample in low and middle income countries typically requires resource-intensive household level sampling with door-to-door data collection. High mobile phone penetration rates in developing countries provide new opportunities for alternative sampling and data collection methods, but there is limited information about response rates and sample biases in coverage and nonresponse using these methods. We utilized data from an interactive voice response, random-digit dial, national mobile phone survey in Ghana to calculate standardized response rates and assess representativeness of the obtained sample. Materials and methods The survey methodology was piloted in two rounds of data collection. The final survey included 18 demographic, media exposure, and health behavior questions. Call outcomes and response rates were calculated according to the American Association of Public Opinion Research guidelines. Sample characteristics, productivity, and costs per interview were calculated. Representativeness was assessed by comparing data to the Ghana Demographic and Health Survey and the National Population and Housing Census. Results The survey was fielded during a 27-day period in February-March 2017. There were 9,469 completed interviews and 3,547 partial interviews. Response, cooperation, refusal, and contact rates were 31%, 81%, 7%, and 39% respectively. Twenty-three calls were dialed to produce an eligible contact: nonresponse was substantial due to the automated calling system and dialing of many unassigned or non-working numbers. Younger, urban, better educated, and male respondents were overrepresented in the sample. Conclusions The innovative mobile phone data collection methodology yielded a large sample in a relatively short period. Response rates were comparable to other surveys, although substantial coverage bias resulted from fewer women, rural, and older residents completing the mobile phone survey in

    Generating a nationally representative sample in low and middle income countries typically requires resource-intensive household level sampling with door-to-door data collection. High mobile phone penetration rates in developing countries provide new opportunities for alternative sampling and data collection methods, but there is limited information about response rates and sample biases in coverage and nonresponse using these methods. We utilized data from an interactive voice response, random-digit dial, national mobile phone survey in Ghana to calculate standardized response rates and assess representativeness of the obtained sample. The survey methodology was piloted in two rounds of data collection. The final survey included 18 demographic, media exposure, and health behavior questions. Call outcomes and response rates were calculated according to the American Association of Public Opinion Research guidelines. Sample characteristics, productivity, and costs per interview were calculated. Representativeness was assessed by comparing data to the Ghana Demographic and Health Survey and the National Population and Housing Census. The survey was fielded during a 27-day period in February-March 2017. There were 9,469 completed interviews and 3,547 partial interviews. Response, cooperation, refusal, and contact rates were 31%, 81%, 7%, and 39% respectively. Twenty-three calls were dialed to produce an eligible contact: nonresponse was substantial due to the automated calling system and dialing of many unassigned or non-working numbers. Younger, urban, better educated, and male respondents were overrepresented in the sample. The innovative mobile phone data collection methodology yielded a large sample in a relatively short period. Response rates were comparable to other surveys, although substantial coverage bias resulted from fewer women, rural, and older residents completing the mobile phone survey in comparison to household surveys.

    Nowadays Toxic Industrial Components (TICs) and Toxic Industrial Materials (TIMs) are one of the most dangerous and diffuse vehicle of contamination in urban and industrial areas. The academic world together with the industrial and military one are working on innovative solutions to monitor the diffusion in atmosphere of such pollutants. In this phase the most common commercial sensors are based on “point detection” technology but it is clear that such instruments cannot satisfy the needs of the smart cities. The new challenge is developing stand-off systems to continuously monitor the atmosphere. Quantum Electronics and Plasma Physics (QEP) research group has a long experience in laser system development and has built two demonstrators based on DIAL (Differential Absorption of Light) technology could be able to identify chemical agents in atmosphere. In this work the authors will present one of those DIAL system, the miniaturized one, together with the preliminary results of an experimental campaign conducted on TICs and TIMs simulants in cell with aim of use the absorption database for the further atmospheric an analysis using the same DIAL system. The experimental results are analysed with standard multivariate data analysis technique as Principal Component Analysis (PCA) to develop a classification model aimed at identifying organic chemical compound in atmosphere. The preliminary results of absorption coefficients of some chemical compound are shown together pre PCA analysis. (paper)

    2005-12-01

    Full Text Available This essay reconstructs the Sartrean conception of a dialectics of history and politics, as it is advanced in «In Search of a Method». The principles of Sartre's articulation of Marxism and existentialism are put forward, as well as his reflections on the existential project as the mediation between the economic base of capitalist society and its ideological superstructure, or as the subjective and practical mediation between objective contradictions. The essay argues that this idea of the project is based on an untenable dualism between Knowledge and the real, and that its concomitant notion of the imaginary is problematically formulated as a form of representation. A Marxist approach, without existentialism, can thematize subjectivity and the contingency of history and politics, without dualisms or representationist models of the imaginary.

    Este ensayo reconstruye la concepción sartreana de una dialéctica de la historia y la política, tal y como está esbozada en «Cuestiones de método». Se exponen los principios de su articulación del marxismo y el existencialismo, así como sus reflexiones sobre el proyecto existencial como la mediación entre la base económica de la sociedad capitalista y su superestructura ideológica, o en tanto que la mediación subjetiva y práctica entre contradicciones objetivas. Se argumenta que esta idea del proyecto se basa en un dualismo insostenible entre el Saber y lo real, que el concomitante concepto del imaginario se formula problemáticamente en términos de representación y que una perspectiva marxista, sin existencialismo, permitiría tematizar la subjetividad y la contingencia de la historia y la política sin dualismos ni modelos representacionalistas del imaginario.

    Two essential parameters to weigh the quality of a reinforcing steel bar are the value of its bending force and the maximum pull it can withstand, in order to measure them with higher precision, it is significant to describe the changing tendency of force with time and displacement by drawing a real-time curve directly during the process examining the quality of a bar when the pull exerted is variable continuously. Using C8051F020 as the core component, this paper improves traditional dial instruments whose precision can only reach the second level. Adopting a high precision pulling/pressing force sensor, an amplifier, a two-order Butterworth low-pass filter and a 12-bit AD converter which is in the C8051F020, the first level of precision can be obtained. A rotary encoder is used to measure the length increment of the bar during the pulling process, based on an algorithm, a force-displacement (or time) curve which is quite important for operators to control the course of experiment can be displayed on the LCD. Meanwhile, real-time experimental data can be stored in local flash, or uploaded to PC by RS-485 and stored in the center database. A real-time clock is also adopted to mark the time of each experiment that is useful to index the data. The measure system we describe here is characterized by simple structure, high precision and stabilization, and convenience operation, can be used in other actual measure systems by only changing the front sensor, so it is of great value of application and popularization.

Se obtuvieron perfiles de AFLP ("amplified fragment length polymorphism" y de polipéptidos del pericarpio en cuatro estados de madurez del fruto de 15 genotipos. Se evaluaron, entre otros: peso, acidez titulable, pH, vida poscosecha y firmeza. Se calculó el porcentaje de polimorfismo para los marcadores moleculares y el porcentaje de variabilidad genética para los caracteres cuantitativos en el grupo de líneas recombinantes, el de híbridos y el conjunto de genotipos. Se realizaron análisis de agrupamiento con cada nivel de variación genética. Para AFLP, el porcentaje de polimorfismo varió entre 34 y 54% y, para los perfiles polipeptídicos, entre 40 y 78%. Mayor polimorfismo fue observado en el grupo de híbridos. La variabilidad genética fue de 100% para acidez y 34% para firmeza, con los mayores valores en los parentales. La similitud genética varió entre los genotipos según el nivel de variación genética; pero la consistencia en el agrupamiento de algunas líneas recombinantes y sus híbridos fue conservada, lo que evidenció asociaciones entre los datos moleculares y fenotípicos.

    2011-01-01

    This paper examines several pioneering genre paintings by the important scholar painter Yun Duseo (1668-1715), with its focus on their artistic sources which have not yet been explored so far. Painted on ramie, 'Women Picking Potherbs' is one of the most intriguing examples among Yun Duseo's oeuvre, which encompasses a broad variety of themes, including genre imagery, landscapes, portraits, dragons, and horses. Even among Yun Duseo's genre paintings, 'Women Picking Potherbs' is extraordinary, as recent scholarship regards it as the earliest independent representation of lower-class women in the history of Korean art. In particular, Yun Duseo painted two women who were working ourdoors to gather spring potherbs. In a conservative Confucian society, it was extraordinary women who were working outdoors. Hence, Yun Duseo occupies a highly important place in Korean painting. Furthermore, even though Yun Duseo came from the upper-class, he often painted images of lower class people working. It is possible that Yun Duseo was familiar with the book titled "Tian gong kai wu" (Exploitation of the Works of Nature) which was published in the 17th century. By identifying the probable body of his artistic sources in the book known as "Tian gong kai wu," it will be possible to assess the innovations and limitations found in 'Women Picking Potherbs'.

    Considering the increase of atmospheric pollution levels in our cities, due to emissions from vehicles and domestic heating, and the growing threat of terrorism, it is necessary to develop instrumentation and gather know-how for the automatic detection and measurement of dangerous substances as quickly and far away as possible. The Multi- Wavelength DIAL, an extension of the conventional DIAL technique, is one of the most powerful remote sensing methods for the identification of multiple substances and seems to be a promising solution compared to existing alternatives. In this paper, first in-field tests of a smart and fully automated Multi-Wavelength mini-DIAL will be presented and discussed in details. The recently developed system, based on a long-wavelength infrared (IR-C) CO2 laser source, has the potential of giving an early warning, whenever something strange is found in the atmosphere, followed by identification and simultaneous concentration measurements of many chemical species, ranging from the most important Greenhouse Gases (GHG) to other harmful Volatile Organic Compounds (VOCs). Preliminary studies, regarding the fingerprint of the investigated substances, have been carried out by cross-referencing database of infrared (IR) spectra, obtained using in-cell measurements, and typical Mixing Ratios in the examined region, extrapolated from the literature. First experiments in atmosphere have been performed into a suburban and moderately-busy area of Rome. Moreover, to optimize the automatic identification of the harmful species to be recognized on the basis of in cell measurements of the absorption coefficient spectra, an advanced multivariate statistical method for classification has been developed and tested.

    The life of Giovanni Cingolani (Montecassiano, 1859 – Santa Fe, 1932 takes place between Italy and Argentina at the turn of the 19th and 20th centuries. Cingolani redeems his humble origins with a successful career as a painter and restorer in Rome between 1880 and 1908. Thanks to the relations with prelates and painters of Perugia, close to Pope Leo XIII, the artist fits himself in the papal circles, devoting himself to painting religious and to the portrait. Came into contact with Ludovico Seitz, director of the Vatican Museums, participates in the major restorations in the Borgia apartment, in the chapel Niccolina, in the Vatican Stanze and in the Sistine Chapel. In 1909 he emigrated to Santa Fe, where he worked as a church decorator and portrait painter, devoting himself intensely to teaching: thanks to unpublished documents, especially the correspondence between Cingolani, his daughter Leonilde and the director of the library of Macerata, Giovanni Spadoni, you can learn many details about his life and the Italian and Argentines artistic milieus he frequented. The paper wants to disclose this almost unknown artist, “migrant” between Italy and Argentina, highlighting his role of disseminator of European academic tradition in Latin America.

    Diabetes self-management education is an essential element of diabetes care. Systems based on information and communication technology (ICT) for supporting lifestyle modification and self-management of diabetes are promising tools for helping patients better cope with diabetes. An earlier study had determined that diet improved and HbA1c declined for the patients who had used DialBetics during a 3-month randomized clinical trial. The objective of the current study was to test a more patient-friendly version of DialBetics, whose development was based on the original participants' feedback about the previous version of DialBetics. DialBetics comprises 4 modules: data transmission, evaluation, exercise input, and food recording and dietary evaluation. Food recording uses a multimedia food record, FoodLog. A 1-week pilot study was designed to determine if usability and compliance improved over the previous version, especially with the new meal-input function. In the earlier 3-month, diet-evaluation study, HbA1c had declined a significant 0.4% among those who used DialBetics compared with the control group. In the current 1-week study, input of meal photos was higher than with the previous version (84.8 ± 13.2% vs 77.1% ± 35.1% in the first 2 weeks of the 3-month trial). Interviews after the 1-week study showed that 4 of the 5 participants thought the meal-input function improved; the fifth found input easier, but did not consider the result an improvement. DialBetics with FoodLog was shown to be an effective and convenient tool, its new meal-photo input function helping provide patients with real-time support for diet modification. © 2015 Diabetes Technology Society.

    Full Text Available O conceito de prática recobriria o de sistema de ação, não fosse a existência de sistemas de ação sem prática. Resta que uma prática é um sistema de ação. Como conseqüência, suposta a reciprocação de sistema com teoria e uma atenta inspeção nos termos da proposição, há equivalência semântica entre "prática teórica " e "sistema de ação prático". Num e noutro caso, a contradição interna aos pares de conceitos se resolve dialeticamente. Graças à dialética, são fundidos numa unidade de sentido, síntese de tensões opostas. Daí a proposta de uma dialética da prática global, conjuntamente abstrata e histórica. Destotalizada ou à margem dessa dialética, pode ser destacada a ação sem prática, exemplificada no drama. Dramática é precisamente uma ação que não é prática. O tempo e o lugar da prática são a história e o mundo do homem; o tempo e o lugar do drama são a ficção cultural e a substância simbólica. Mimese da prática, o drama, reproduz, não os traços do modelo, mas a sua produção, tornando-se por sua vez modelo do modelo. Mimese não é cópia, é forma autônoma de eficiência, paradoxalmente sem prática mas especular.

    Horizontal carbon dioxide (CO2) distribution and wind profiles are important information for understanding of the regional sink and source of CO2. The differential absorption lidar (DIAL) and the Doppler lidar with the range resolution is expected to bring several advantages over passive measurements. We have developed a new scanning 1.6μm DIAL and incoherent Doppler lidar system to perform simultaniously measurements of CO2 concentration and wind speed profiles in the atmosphere. The 1.6μm DIAL and Doppler lidar system consists of the Optical Parametric Generator (OPG) transmitter that excited by the LD pumped Nd:YAG laser with high repetition rate (500 Hz). The receiving optics include the near-infrared photomultiplier tube with high quantum efficiency operating at the photon counting mode, a fiber Bragg grating (FBG) filter to detct Doppler shift, and a 25 cm telescope[1][2]. Laser beam is transmitted coaxially and motorized scanning mirror system can scan the laser beam and field of view 0-360deg horizontally and 0-52deg vertically. We report the results of vertical CO2 scanning measurenents and vertical wind profiles. The scanning elevation angles were from 12deg to 24deg with angular step of 4deg and CO2 concentration profiles were obtained up to 1 km altitude with 200 m altitude resolution. We also obtained vertical wind vector profiles by measuring line-of-sight wind profiles at two azimuth angles with a fixed elevation angle 52deg. Vertical wind vector profiles were obtained up to 5 km altitude with 1 km altitude rasolution.

    From analyses of bones, estimates were made of the relative intakes of 228 Ra and 226 Ra by the employees of a dial-painting studio that used luminous compounds activated with technical mesothorium. These data, in turn, were used to derive estimates of 228 Ra activity from activities of 226 Ra in living colleagues whose body contents of 226 Ra and 212 Bi had been measured. The indirectly determined 212 Bi to 228 Ra activity ratios in the living workers averaged 1.56 +- 0.10 (S.E.) at a median of 42 yr post intake. If no 228 Ra decay products are excreted, the expected 212 Bi to 228 Ra activity ratio at 42 yr after intake is 1.59 according to the simple power function of radium retention of Norris et al., and 1.72 according to the alkaline earth model of ICRP No. 20. 15 references, 2 tables

Assim, a partir do conceito de intersubjetividade que Hegel desenvolve através de sua filosofia do espírito, pretende-se analisar os fundamentos filosóficos dos pensamentos sociológicos de Karl Marx e de Max Weber. Conclui-se, portanto, que tanto o viés revolucionário do Manifesto Comunista, quanto o viés conservador da Ética Protestante, partem, fundamentalmente, do legado filosófico hegeliano.

    Full Text Available A laser transmitter has been developed and incorporated into a micro-pulse differential absorption lidar (DIAL for water vapor profiling in the lower troposphere as an important step towards long-term autonomous field operation. The laser transmitter utilizes two distributed Bragg reflector (DBR diode lasers to injection seed a pulsed tapered semiconductor optical amplifier (TSOA, and is capable of producing up to 10 mJ of pulse energy with a 1 ms pulse duration and a 10 kHz pulse repetition frequency. The on-line wavelength of the laser transmitter can operate anywhere along the water vapor absorption feature centered at 828.187 nm (in vacuum depending on the prevailing atmospheric conditions, while the off-line wavelength operates at 828.287 nm. This laser transmitter has been incorporated into a DIAL instrument utilizing a 35.6 cm Schmidt-Cassegrain telescope and fiber coupled avalanche photodiode (APD operating in the photon counting mode. The performance of the DIAL instrument was demonstrated over a ten-day observation period. During this observation period, data from radiosondes were used to retrieve water vapor number density profiles for comparisons with the number density profiles retrieved from the DIAL data.

    This article presents the biographies of the apothecaries who lived in the Rue Saint-Honoré in Paris in the 17th century. Two major facts emerge from this study. The first concerns the formation of a family network involving the apothecaries and the royal artists. The apothecaries Antoine and Jacques Grégoire became allied with Simon Vouet, the first painter of Louis XIII . Links were also made between Antoine Grégoire and Jacques Sarazin, the King’s sculptor, and then with Michel Corneille, painter to the King. The famous painting by Simon Vouet hanging in the assembly hall of the Faculty of Pharmacy in Paris is probably the fruit of his collaboration with Jacques Grégoire, his brother-in-law and an erudite botanist. The other notable fact concerns the relations between Anne de Furnes, widow of Antoine Brulon, the rich apothecary to the King Antoine Brulon, and Molière, both in Paris and in the village of Auteuil.

  3. Measurements of CO2 Column Abundance in the Low Atmosphere Using Ground Based 1.6 μm CO2 DIAL

    Changes in atmospheric carbon dioxide (CO2) concentration are believed to produce the largest radiative forcing for the current climate system. Accurate predictions of atmospheric CO2 concentration rely on the knowledge of its sinks and sources, transports, and its variability with time. Although this knowledge is currently unsatisfactory, numerical models use it as a way in simulating CO2 fluxes. Validating and improving the global atmospheric transport model, therefore, requires precise measurement of the CO2 concentration profile. There are two further variations on Lidar: the differential absorption Lidar (DIAL) and the integrated path differential absorption (IPDA) Lidar. DIAL/IPDA are basically for profile/total column measurement, respectively. IPDA is a special case of DIAL and can measure the total column-averaged mixing ratio of trace gases using return signals from the Earth's surface or from thick clouds based on an airborne or a satellite. We have developed a ground based 1.6 μm DIAL to measure vertical CO2 mixing ratio profiles from 0.4 to 2.5 km altitude. The goals of the CO2 DIAL are to produce atmospheric CO2 mixing ratio measurements with much smaller seasonal and diurnal biases from the ground surface. But, in the ground based lidar, return signals from around ground surface are usually suppressed in order to handle the large dynamic range. To receive the return signals as near as possible from ground surface, namely, the field of view (FOV) of the telescope must be wide enough to reduce the blind range of the lidar. While the return signals from the far distance are very weak, to enhance the sensitivity and heighten the detecting distance, the FOV must be narrow enough to suppress the sky background light, especially during the daytime measurements. To solve this problem, we propose a total column measurement method from the ground surface to 0.4 km altitude. Instead of strong signals from thick clouds such as the IPDA, the proposed method uses

    In this paper we report, for the first time to our knowledge, on lidar/DIAL detection of acetone vapors at 3.3 μm by means of an optical parametric tunable laser system. After a preliminary spectroscopic study in an absorption cell, the feasibility of a differential absorption (DIAL) lidar for the detection of acetone vapors has been investigated in the laboratory, simulating the experimental conditions of a field campaign. Having in mind measurements in a real scenario, a study of possible atmospheric intereferents has been performed, looking for all known compounds that share acetone IR absorption in the spectral band selected for its detection. Possible interfering species from urban and industrial atmospheres were investigated and limits of acetone detection in both environments were identified. This study confirmed that a lidar system can detect a low concentration of acetone at considerable distances. (paper)

    The main purpose of the NASA Goddard Space Flight Center TROPospheric OZone DIfferential Absorption Lidar (GSFC TROPOZ DIAL) is to measure the vertical distribution of tropospheric ozone for science investigations. Because of the important health and climate impacts of tropospheric ozone, it is imperative to quantify background photochemical ozone concentrations and ozone layers aloft, especially during air quality episodes. For these reasons, this paper addresses the necessary procedures to validate the TROPOZ retrieval algorithm and confirm that it is properly representing ozone concentrations. This paper is focused on ensuring the TROPOZ algorithm is properly quantifying ozone concentrations, and a following paper will focus on a systematic uncertainty analysis. This methodology begins by simulating synthetic lidar returns from actual TROPOZ lidar return signals in combination with a known ozone profile. From these synthetic signals, it is possible to explicitly determine retrieval algorithm biases from the known profile. This was then systematically performed to identify any areas that need refinement for a new operational version of the TROPOZ retrieval algorithm. One immediate outcome of this exercise was that a bin registration error in the correction for detector saturation within the original retrieval was discovered and was subsequently corrected for. Another noticeable outcome was that the vertical smoothing in the retrieval algorithm was upgraded from a constant vertical resolution to a variable vertical resolution to yield a statistical uncertainty of exercise was quite successful.

    We report the control of guest release profiles by dialing-in desirable interactions between guest molecules and pores in metal-organic frameworks (MOFs). The interactions can be derived by the rate constants that were quantitatively correlated with the type of functional group and its proportion in the porous structure; thus the release of guest molecules can be predicted and programmed. Specifically, three probe molecules (ibuprofen, rhodamine B, and doxorubicin) were studied in a series of robust and mesoporous MOFs with multiple functional groups [MIL-101(Fe)-(NH 2 ) x , MIL-101(Fe)-(C 4 H 4 ) x , and MIL-101(Fe)-(C 4 H 4 ) x (NH 2 ) 1-x ]. The release rate can be adjusted by 32-fold [rhodamine from MIL-101(Fe)-(NH 2 ) x ], and the time of release peak can be shifted by up to 12 days over a 40-day release period [doxorubicin from MIL-101(Fe)-(C 4 H 4 ) x (NH 2 ) 1-x ], which was not obtained in the physical mixture of the single component MOF counterparts nor in other porous materials. The corelease of two pro-drug molecules (ibuprofen and doxorubicin) was also achieved.

    Full Text Available Portable inhalers are divisible into those that deliver medication by patient triggering (pMDIs: a gentle slow inhalation and those that use the patient’s inspiratory effort as the force for deaggregation and delivery (DPIs: a stronger deeper inspiratory effort. Patient confusion and poor technique are commonplace. The use of training tools has become standard practice, and unique amongst these is an inspiratory flow meter (In-Check which is able to simulate the resistance characteristics of different inhalers and, thereby, guide the patient to the correct effort. In-Check’s origins lie in the 1960s peak expiratory flow meters, the development of the Mini-Wright peak flow meter, and inspiratory flow assessment via the nose during the 1970s–1980s. The current device (In-Check DIAL G16 is the third iteration of the original 1998 training tool, with detailed and ongoing assessments of all common inhaler resistances (including combination and breath-actuated inhaler types summarised into resistance ranges that are preset within the device. The device works by interpolating one of six ranges with the inspiratory effort. Use of the tool has been shown to be contributory to significant improvements in asthma care and control, and it is being advocated for assessment and training in irreversible lung disease.

    SRI International designed and constructed a DIfferential Absorption Lidar (DIAL) to provide EPRI with a mobile field system for remote measurements of SO/sub 2/, NO/sub 3/, and O/sub 3/. After field testing the lidar was prepared for the sytem calibration testing where lidar measurements were compared to in situ profiles of SO/sub 2/, NO/sub 2/, and O/sub 3/. This two-week field program determined overall system accuracy and reliability in measuring varying ambient gas concentrations. The lidar was then returned to SRI for detailed subsystem performance evaluations. Improvements were made wherever possible, and the lidar was prepared for further systems tests. Tests were made using an NO/sub 2/ sample chamber to simulate a calibrated NO/sub 2/ plume, and ambient measured NO/sub 2/ concentrations were compared with values from a regional air pollutant monitoring station. Following the local calibration and the systems field tests, SRI evaluated the performance and reliability of the EPRI lidar. Based on that evaluation, SRI undertook a major analysis of possible system improvements. Although the remote measuring capability had been successfully demonstrated in the field program, SRI makes several recommendations for systems improvements which would increase the lidar accuracy and reliability.

    In urban areas, logistic transportation operations often run into problems because travel speeds change, depending on the current traffic situation. If not accounted for, time-dependent and stochastic travel speeds frequently lead to missed time windows and thus poorer service. Especially in the case of passenger transportation, it often leads to excessive passenger ride times as well. Therefore, time-dependent and stochastic influences on travel speeds are relevant for finding feasible and reliable solutions. This study considers the effect of exploiting statistical information available about historical accidents, using stochastic solution approaches for the dynamic dial-a-ride problem (dynamic DARP). The authors propose two pairs of metaheuristic solution approaches, each consisting of a deterministic method (average time-dependent travel speeds for planning) and its corresponding stochastic version (exploiting stochastic information while planning). The results, using test instances with up to 762 requests based on a real-world road network, show that in certain conditions, exploiting stochastic information about travel speeds leads to significant improvements over deterministic approaches.

    A standardized approach for the definition, propagation, and reporting of uncertainty in the ozone differential absorption lidar data products contributing to the Network for the Detection for Atmospheric Composition Change (NDACC) database is proposed. One essential aspect of the proposed approach is the propagation in parallel of all independent uncertainty components through the data processing chain before they are combined together to form the ozone combined standard uncertainty. The independent uncertainty components contributing to the overall budget include random noise associated with signal detection, uncertainty due to saturation correction, background noise extraction, the absorption cross sections of O3, NO2, SO2, and O2, the molecular extinction cross sections, and the number densities of the air, NO2, and SO2. The expression of the individual uncertainty components and their step-by-step propagation through the ozone differential absorption lidar (DIAL) processing chain are thoroughly estimated. All sources of uncertainty except detection noise imply correlated terms in the vertical dimension, which requires knowledge of the covariance matrix when the lidar signal is vertically filtered. In addition, the covariance terms must be taken into account if the same detection hardware is shared by the lidar receiver channels at the absorbed and non-absorbed wavelengths. The ozone uncertainty budget is presented as much as possible in a generic form (i.e., as a function of instrument performance and wavelength) so that all NDACC ozone DIAL investigators across the network can estimate, for their own instrument and in a straightforward manner, the expected impact of each reviewed uncertainty component. In addition, two actual examples of full uncertainty budget are provided, using nighttime measurements from the tropospheric ozone DIAL located at the Jet Propulsion Laboratory (JPL) Table Mountain Facility, California, and nighttime measurements from the JPL

    Full Text Available O presente trabalho apresenta a dialógica enquanto perspectiva de pesquisa transdiciplinar. O texto começa por referir o percurso seguido por Mikhail Bakthin, Paulo Freire, Edgar Morin e Basarab Nicolescu ao trabalharem a metodologia dialógica em suas obras. Além disso, discute a transdiciplinaridade compreendida em seu aspecto metodológico, como processo que ocorre em três etapas simultâneas: análise de diferentes níveis de realidade, a lógica do terceiro incluído e a complexidade. Buscou-se, através da pesquisa bibliográfica, levantar pontos teóricos sobre a dialogia e pesquisa transdisciplinas entre os autores supracitados. Na dialógica não se rejeita nenhuma flecha do conhecimento, o processo de conhecimento disciplinar, multidisciplinar, pluridisciplinar, interdisciplinar fazem parte da unidade na diversidade que compõe a transdiciplinaridade. Nesta perspectiva, Nicolescu (2000 diz que não há superação de um nível anterior de conhecimento, mas que os opostos coexistem e que, portanto, o princípio retroativo e de autorregulação ocorrem simultaneamente. Por isso, é um importante caminho metodológico para as ciências sociais.

Essentially it proposes a new Western philosophy beginning, starting from the ontological duality established by the presocratics and maintained by Aristotle against the monological reason of Plato’s teachings. Starting from a new point of view on the Nicomachean and Eudemian ethics, the author puts forward a critique of modern views on Aristotle’s virtue theory, including MacIntyre, in order to propose a new approach to connect the practice of virtue to radical democracy.

  2. De la locura y la inseguridad del derecho a la racionalidad y el orden de la ley. Lectura dialéctica de Thomas Hobbes

    Full Text Available I take for granted as a starting-point the anthropological antinomy on the individual/social nature of man. This antinomy is constituted politically in Hobbes’ thought as the antinomy individual/society, whose legal expression gives rise to the antinomy right/law —in his iusnaturalist conception— which reflects as well the anthropological antinomy passion/reason. This dialectical conception is only implicit in his political and legal philosophy; however, it becomes obvious if the underlying anthropology is analysed. Therefore, the problems derived from this dialectics require a dialectical solution in accordance with the dialecticity of its anthropological foundation. That is why Hobbes’ legal and political philosophy was not and is not still adequate or effective, but in a partial or negative way.

    Asumo como punto de partida la antinomia antropológica de la naturaleza individual/ social del hombre, que se constituye en el pensamiento de Hobbes, políticamente, como la antinomia indviduo/sociedad, cuya expresión jurídica da lugar a la antinomia derecho/ ley, en su concepción iusnaturalista, que refleja asimismo la antinomia antropológica pasión/razón. Tal concepción dialéctica sólo está implícita en su Filosofía Política y Filosofía del Derecho, pero se hace bien patente si analizamos la antropología subyacente en ella. Por lo tanto, los problemas que esta dialéctica origina requieren una solución o salida dialéctica de acuerdo a la dialecticidad de su fundamento antropológico. Por eso la filosofía jurídica y política de Hobbes no pudo ni puede ser adecuada ni efectiva sino parcial o negativamente.

Lastly, a characterization of dialectic features based on previous analysis is introduced. The present article argues against the unique dialectic and its a priori features in Developmental Psychology and Human Sciences areas. It also justifies its diversity in relation to the subject matters under investigation as well as the existence of certain limits in the use of that category in empirical research. The use of dialectics requires the adoption of diverse forms regarding different issues and theoretical focuses.

    Objective An up-to-date meta-analysis of experimental research on talking and driving is needed to provide a comprehensive, empirical, and credible basis for policy, legislation, countermeasures, and future research. Background The effects of cell, mobile, and smart phone use on driving safety continues to be a contentious societal issue. Method All available studies that measured the effects of cell phone use on driving were identified through a variety of search methods and databases. A total of 93 studies containing 106 experiments met the inclusion criteria. Coded independent variables included conversation target (handheld, hands-free, and passenger), setting (laboratory, simulation, or on road), and conversation type (natural, cognitive task, and dialing). Coded dependent variables included reaction time, stimulus detection, lane positioning, speed, headway, eye movements, and collisions. Results The overall sample had 4,382 participants, with driver ages ranging from 14 to 84 years ( M = 25.5, SD = 5.2). Conversation on a handheld or hands-free phone resulted in performance costs when compared with baseline driving for reaction time, stimulus detection, and collisions. Passenger conversation had a similar pattern of effect sizes. Dialing while driving had large performance costs for many variables. Conclusion This meta-analysis found that cell phone and passenger conversation produced moderate performance costs. Drivers minimally compensated while conversing on a cell phone by increasing headway or reducing speed. A number of additional meta-analytic questions are discussed. Application The results can be used to guide legislation, policy, countermeasures, and future research.

    Five flight tests of the Digital Automated Landing System (DIALS) were conducted on the Advanced Transport Operating Systems (ATOPS) Transportation Research Vehicle (TSRV) -- a modified Boeing 737 aircraft for advanced controls and displays research. These flight tests were conducted at NASA's Wallops Flight Center using the microwave landing system (MLS) installation on runway 22. This report describes the flight software equations of the DIALS which was designed using modern control theory direct-digital design methods and employed a constant gain Kalman filter. Selected flight test performance data is presented for localizer (runway centerline) capture and track at various intercept angles, for glideslope capture and track of 3, 4.5, and 5 degree glideslopes, for the decrab maneuver, and for the flare maneuver. Data is also presented to illustrate the system performance in the presence of cross, gust, and shear winds. The mean and standard deviation of the peak position errors for localizer capture were, respectively, 24 feet and 26 feet. For mild wind conditions, glideslope and localizer tracking position errors did not exceed, respectively, 5 and 20 feet. For gusty wind conditions (8 to 10 knots), these errors were, respectively, 10 and 30 feet. Ten hands off automatic lands were performed. The standard deviation of the touchdown position and velocity errors from the mean values were, respectively, 244 feet and 0.7 feet/sec.

    The NASA Langley Research Center's airborne UV Differential Absorption Lidar (DIAL) system participated in the Subsonic Assessment, Ozone and Nitrogen Oxide Experiment (SONEX) mission from October 13 to November 12, 1997. The purpose of the mission was to study the upper troposphere/lower stratosphere in and near the North Atlantic flight corridor to better understand this region of the atmosphere and how civilian air travel in the corridor might be affecting the atmospheric chemistry. Bases of operations included NASA Ames, California (37.4 deg N, 122.1 deg W); Bangor, Maine (44.8 deg N, 68.8 deg W); Shannon, Ireland (52.7 deg N, 8.9 deg W); and Lajes, Terceira Island, Azores (38.8 deg N, 27.1 deg W). Since the UV DIAL system observes in the nadir as well as the zenith, aerosol and ozone data were obtained from near the Earth's surface to the lower stratosphere. A number of interesting features were noted relating to both chemistry and dynamics of the troposphere, which are reported here.

    Unlike the existing 2.0μm CO2-DIAL, a high-energy pulse laser operating in the 1.6μm absorption band of CO2 has not been realized. Quasi phase matching (QPM) devices have high conversion efficiency and high beam quality due to their higher nonlinear optical coefficient. We adapt the PPMgLT crystal as the QPM device. The PPMgLT crystal had 3mm × 3mm apertures, and the periodically poled period was 30.9 μm, with the duty ratio close to the ideal value of 0.5. The beam quality of the pumping laser was exceed M2 ≥1.2. The repetition rate was 400 Hz and the energy was 35 mJ. The pumping laser pulse was injection-seeded by the continuous-wave (CW) fiber laser, which had a narrow spectrum. The pulse pumped the PPMgLT crystal in the ring cavity with a single pass through the dielectric mirror. The PPMgLT crystal was mounted on a copper holder, and the temperature was maintained at 40 °C using a Peltier module. The holder’s temperature was stabilized to within 0.01 °C when the copper holder was covered with a plastic case. The OPO ring cavity was a singly resonant oscillator optimized for the signal wave. Single-frequency oscillation of the PPMgLT OPO was achieved by injection seeding, as described in the following. The injection seeder was a DFB laser having a power of 30mW with a 1MHz oscillation spectrum. Their oscillation wavelength was coarse tuned by temperature and fine tuned by adjusting injection currents. The partial power of the online wavelength was split in the wavelength control unit. We locked the DFB laser as an injection seeder of the online wavelength onto the line center by referencing the fiber coupled multipath gas cell (path length 800mm) containing pure CO2 at a pressure of 700 Torr. Stabilization was estimated to within 1.8MHz rms of the line center of the CO2 absorption line by monitoring the feedback signal of a wavelength-controlled unit. Injection seeding of the PPMgLT OPO was performed by matching the cavity length to the seeder

    due città ha delle ripercussioni anche sul linguaggio artistico dei veronesi, il quale si differenzia dalla restante arte veneta – in massima parte influenzata dalla tradizione veneziana – proprio per una certa affinità con la pittura lombarda.   The study aims to illustrate (when it is possible also through artists’ writings the stories of the Verona’s painters who, in the nineteenth century, seek their fortune in Milan, which was the most updated artistic center in North Italy, especially beaucase of its Academy and its frequented exhibitions. This "migration" occurs because, during the Hapsburg’s rule (1815 - 1866, Verona becomes the pivot of the military system of the Regno Lombardo - Veneto and, consequently, the development of the city is subordinated to the needs of the military companies that stay or transit through its territory. Therefore military buildings and the means for long distance communications are increased, but the development of the city and the creation of small industries and businesses, that can help Verona’s people, are disregarded. In this situation, the art market is slack, both for the lack of public and private buyers, and for the few exhibitions organized during these difficult years. Also the Verona’s Academy experiences hard tiemes, due to outdated teaching methods and to the lack of money: in this situation the quality of teaching gets worse, so the artists, who have studied at this school, are unprepared to compete with painters coming from other italian Academies. After the unification of Italy and especially after the reform of the School of fine art of Verona (1873, the relationship between Verona and Milan becomes more complex: not only Verona’s painters go to Milan for studing and exhibiting their works of art, but also the authors from Lombardia do not disdain the shows of the Venetian city and even they aim at the direction of Verona’s Academy. Finally, it should be noted that the link between the two

    Repasky, Kevin

    2014-03-31

    A scanning differential absorption lidar (DIAL) instrument for monitoring carbon dioxide has been developed. The laser transmitter uses two tunable discrete mode laser diodes (DMLD) operating in the continuous wave (cw) mode with one locked to the online absorption wavelength and the other operating at the offline wavelength. Two in-line fiber optic switches are used to switch between online and offline operation. After the fiber optic switch, an acousto- optic modulator (AOM) is used to generate a pulse train used to injection seed an erbium doped fiber amplifier (EDFA) to produce eye-safe laser pulses with maximum pulse energies of 66 {micro}J, a pulse repetition frequency of 15 kHz, and an operating wavelength of 1.571 {micro}m. The DIAL receiver uses a 28 cm diameter Schmidt-Cassegrain telescope to collect that backscattered light, which is then monitored using a photo-multiplier tube (PMT) module operating in the photon counting mode. The DIAL instrument has been operated from a laboratory environment on the campus of Montana State University, at the Zero Emission Research Technology (ZERT) field site located in the agricultural research area on the western end of the Montana State University campus, and at the Big Sky Carbon Sequestration Partnership site located in north-central Montana. DIAL data has been collected and profiles have been validated using a co-located Licor LI-820 Gas Analyzer point sensor.

    Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In addition to the ground level CO2 network, vertical CO2 concentration profiles also play an important role for the estimation of the carbon budget and global warming in the inversion method. Especially, for the detailed analysis of forest carbon dynamics and CO2 fluxes of urban area, vertical CO2 concentration profiles with high spatial and temporal resolution in the lower atmosphere have been conducted by a differential absorption lidar (DIAL). We have observed several vertical profiles of CO2 concentrations for nighttime and daytime from 0.25 to 2.5 km altitude with range resolution of 300 m and integration time of 1 hour. In order to extract information on the origin of the CO2 masses, one day back trajectories were calculated by using a three dimensional (3-D) atmospheric transport model. In many cases, CO2 low concentration layers of over 1.5km altitude were flown by westerly winds from the forest. In another case, high concentration layers of CO2 were flown from the urban areas. As the spectra of absorption lines of any molecules are influenced basically by the temperature in the atmosphere, laser beams of three wavelengths around a CO2 absorption spectrum are transmitted alternately to the atmosphere for simultaneous measurements of CO2 concentration and temperature profiles. Moreover, a few processing algorithms of CO2-DIAL are also performed for improvement of measurement accuracy. For computation of trajectories and drawing their figures, the JRA-25 data provided by the cooperative research project for the JRA-25 long-term reanalysis of the Japan Meteorological Agency (JMA) and the Central Research Institute of Electric Power Industry (CRIEPI) and the NIPR trajectory model (Tomikawa and Sato, 2005; http://firp-nitram.nipr.ac.jp) were used.

Ele afirma que as categorias da Lógica de Hegel e aquelas do início de O Capital de Marx mostram uma homologia impressionante [...] à luz de algum trabalho de reconstrução menor. (Arthur, 2004, p. 4. Este ensaio critica a leitura de Arthur de Marx e, especialmente, de Hegel contra o background das importantes contribuições para os estudos de Hegel das últimas décadas. Estes estudos foram pioneiros na teoria da dialética e na teoria das categorias, na sistematização da estrutura antinômica do conceito e o problema do pressuposto semântico-pragmático (semantisch-pragmatischer Präsuppositionsbegriff da exposição científica. Não obstante o seu caráter fundamental para um tratamento erudito e para a compreensão da dialética de Hegel, essas abordagens estão ausentes na intervenção de Arthur.

  1. Development of the 1.6μm OPG/OPA system wavelength-controlled precisely for CO2 DIAL

    2010-12-01

    We developed an optical parametric oscillator (OPO) laser system for 1.6μm CO2 DIAL1). In order to improve the measurement accuracy of CO2 profiles, development of high power and wavelength stabilized laser system has been conducted. We report a new high-power 1.6μm laser transmitter based on a parametric master oscillator-power amplifier (MOPA) system pumped by a LD-pumped Q-switched Nd:YAG laser which has the injection seed laser locked to the iodine absorption line. The master oscillator is an optical parametric generator (OPG), based on an MgO-doped periodically poled LiTaO3 (PPMgLT) crystal. The OPOs require either active control of the cavity length or slight misalignment of the cavity. On the other hand, the OPGs do not require a cavity and instead rely on sufficient conversion efficiency to be obtained with a single pass through the crystal. The single-frequency oscillation of the OPG was achieved by injection seeding. The 1.6μm emission of the OPG is amplified by two-stage optical parametric amplifiers (OPAs). The each PPMgLT crystal was mounted on the copper holder, and the temperature control of the each holder was carried out within 0.01 K. The wavelength feedback system of the Nd:YAG seed laser is performed with the side locking of the iodine absorption spectrum (line No.1107) and the frequency stability is realized within 10 MHz rms. Stabilization of the 1.6μm DFB seed laser is estimated to within 4 MHz rms at the CO2 absorption line center and within 1.8 MHz rms at the CO2 absorption line slope using the wavelength control unit. We demonstrated single-longitudinal-mode emission with the OPG and two OPAs. The beam quality was TEM00 mode, the pulse energy was 12 mJ at 500 Hz repetition rate and the frequency stability was less than 10MHz rms. The unique performances of this optical parametric system make a relevant transmitter for CO2 DIAL.

    The Dialé-Daléma group is located in the eastern part of the Kédougou-Kenieba Inlier (KKI) and is essentially composed of Paleoproterozoic rock formations. Lithostructural studies in this area, hassuggested, often controversial, deformational regimes and geodynamic evolution models. In this study, we suggest the existence of an initial tangential D1 deformation and transpressional D2 deformational phases. D1 is characterized by an initial metamorphic schistosity denoted as S1 and by F1 folds with the main shortening stress direction generally oriented in NW-SE direction. D2 in the study area is divided into two stages. The first stage designated as D2a is coaxial and compressive in nature. It is characterized by a N-S to NNE-SSW trending metamorphic schistosity termed S2a. The D2a phase evolves gradually to a transcurrent phase connoted as D2b and characterized by a NNE-SSW S2b metamorphic schistosity which is axial planar to the F2b folds with subvertical fold axes. During the D2 phase, the main shortening stress direction rotates gradually in a clockwise motion from an E-W to a NW-SE direction within a continuum of deformation. The third deformation phase D3 in the Dialé-Daléma basin, is also divided into two stages, thus D3a and D3b. D3a is transcurrent and transtensive in nature and is characterized by NE-SW sinistral shear corridors with local extensional jogs. During this deformation stage, the maximum shortening stress (σ1) direction acts in a N-S direction and rotate to a NE-SW direction, thereby creating a N-S transcurrent dextral shear corridors. D3b component of the D3 deformation is compressive in nature with a weak sinistral shear component. The D4 corresponds to a N-S extensional phase which is characterized by E-W directed normal faults. D4 in the study area denotes the final stage of the evolution of the Eburnean orogeny in the KKI.

    Full Text Available Resumo Este ensaio aborda o papel da informação e do conhecimento ao longo do desenvolvimento do modo de produção capitalista, especialmente na atualidade, quando ganham popularidade termos como sociedade da informação e do conhecimento, economia do conhecimento, capital intelectual e capital humano. Nosso ponto de partida será a apresentação de alguns fundamentos da dialética materialista, filosofia precursora da investigação das relações entre capital e conhecimento. Indo além da luz lançada por Marx sobre essa obscura problemática, esse texto também destaca algumas teorias de autores contemporâneos que, partindo das concepções marxistas, tentam explicar a realidade do século XXI a partir da subsunção, em maior ou menor grau, do trabalho pelo capital. Essa perspectiva permite afirmar que a dominação das condições de trabalho no modo de produção capitalista avança a passos largos em busca da apropriação privada do intelecto geral. Palavras-chave informação, conhecimento, capitalismo, dialética materialista, apropriação privada do intelecto geral Abstract This essay discusses the role of information and knowledge throughout the development of the capitalist mode of production, especially nowadays, when some terms become popular such as information and knowledge society, knowledge economy, intellectual capital and human capital. Our starting point is the presentation of some foundations of dialectical materialism, a precursor philosophy to investigate the relationships between capital and knowledge. Drawing on Marxist ideas and going beyond in this obscure issue, this paper also highlights some theories of contemporary authors which, starting from Marxist concepts, attempt to explain the 21st century reality based on the subsumption of labor under capital in a greater or lesser extent. This perspective allows us to assert that the domination of working conditions in the capitalist mode of production has

    Full Text Available Resumo: Ressaltamos a importância do estudo da gênese do self dialógico. Propomos que esse self emerge e se desenvolve no processo de comunicação em face do Outro. Tendo como foco a história da díade mãe-bebê nos primeiros oito meses de vida do bebê, sugerimos que tanto os padrões de organização do diálogo - atingindo a forma abreviada do diálogo - como a análise das posições que assume a fala da mãe denotam um processo de diferenciação do bebê como parceiro nesse diálogo. Também, o despontar do bebê como agente e sua subjetividade emergem respaldados no desenrolar da historia construída pela díade. Essa historicidade, possível de ser construída através de uma emergente capacidade do bebê de distanciamento e, portanto, capaz de abstrair as ações do contexto imediato no qual ocorrem, se constitui como um terceiro polo do diálogo, formando, então, uma relação triádica.

    Full Text Available Este ensayo explora la idea de justicia social y, teniendo en cuenta el papel del espacio público, el pensamiento utópico de David Harvey sobre el futuro de las ciudades. Este conocido geógrafo Inglés, que vive en EE.UU., dedica su vida a construir una teoría del desarrollo geográfico desigual que objetiva elaborar propuestas alternativas que empiecen un proceso continuo de cambios progresistas en la búsqueda de una sociedad más justa. El artículo analiza varios de sus escritos y construcciones teóricas, incluyendo a las que se refieren a la “justicia distributiva territorial” y el “utopianismo dialéctico”, como también las versiones modificadas del “derecho a la ciudad”, de Henri Lefebvre, y de “cosmopolitismo subalterno”, de Boaventura de Souza Santos. Harvey piensa que es fundamental que toda la infraestructura física y el aparato institucional producidos por la sociedad burguesa en los últimos 500 años sean sustituidos por otros sistemas que den origen a un espacio y lugar relacional alternativo, construido a partir de una “reflexión filosófica”, una “evaluación de requerimientos prácticos y de necesidades humanas básicas” y del “fermento de los movimientos sociales”.

    Random-digit dialing (RDD) using landline telephone numbers is the historical gold standard for control recruitment in population-based epidemiologic research. However, increasing cell-phone usage and diminishing response rates suggest that the effectiveness of RDD in recruiting a random sample of the general population, particularly for younger target populations, is decreasing. In this study, we compared landline RDD with alternative methods of control recruitment, including RDD using cell-phone numbers and address-based sampling (ABS), to recruit primarily white men aged 18-55 years into a study of testicular cancer susceptibility conducted in the Philadelphia, Pennsylvania, metropolitan area between 2009 and 2012. With few exceptions, eligible and enrolled controls recruited by means of RDD and ABS were similar with regard to characteristics for which data were collected on the screening survey. While we find ABS to be a comparably effective method of recruiting young males compared with landline RDD, we acknowledge the potential impact that selection bias may have had on our results because of poor overall response rates, which ranged from 11.4% for landline RDD to 1.7% for ABS.

    The design and development of a 3-D Digital Integrated Automatic Landing System (DIALS) for the Terminal Configured Vehicle (TCV) Research Aircraft, a B-737-100 is described. The system was designed using sampled data Linear Quadratic Gaussian (LOG) methods, resulting in a direct digital design with a modern control structure which consists of a Kalman filter followed by a control gain matrix, all operating at 10 Hz. DIALS uses Microwave Landing System (MLS) position, body-mounted accelerometers, as well as on-board sensors usually available on commercial aircraft, but does not use inertial platforms. The phases of the final approach considered are the localizer and glideslope capture which may be performed simultaneously, localizer and steep glideslope track or hold, crab/decrab and flare to touchdown. DIALS captures, tracks and flares from steep glideslopes ranging from 2.5 deg to 5.5 deg, selected prior to glideslope capture. Digital Integrated Automatic Landing System is the first modern control design automatic landing system successfully flight tested. The results of an initial nonlinear simulation are presented here.

    The artist began his journey in Italy in the first decade of the 17th century. Starting from Cracovia, he made a stop in Vienna, to then continue on towards Venice, Bologna and then, following the Adriatic coast, arrived in Abruzzo, going down to the chietino. It is very likely that the young painter was called to Teramo at the beginning of the 17th century, the anniversary of the death of Saint Berardo. From this moment on, he settled in the city and, in 1628, was united in matrimony with Cesarea Vannemarini, a very prominent family of Teramo. He noted that, five hundred years after the death of the Saint, the painter was commissioned to portray Saint Berardo in the six paintings depicting the Vita e Miracoli del patrono S. Berardo Life and Miracles of the patron Saint Berardo. Along with the coping with the Holy Family, they adorn the altar in fine walnut of the Baroque style leaning against the wall of the sacristy of the cathedral SS.

  20. The High Accuracy Measurement of CO2 Mixing Ratio Profiles Using Ground Based 1.6 μm CO2-DIAL with Temperature Measurement Techniques in the Lower-Atmosphere

    We have developed a ground based direct detection three-wavelength 1.6 μm differential absorption lidar (DIAL) to achieve measurements of vertical CO2 concentration and temperature profiles in the atmosphere. As the spectra of absorption lines of any molecules are influenced basically by the temperature and pressure in the atmosphere, it is important to measure them simultaneously so that the better accuracy of the DIAL measurement is realized. Conventionally, we have obtained the vertical profile of absorption cross sections using the atmospheric temperature profile by the objective analysis and the atmospheric pressure profile calculated by the pressure height equation. Comparison of atmospheric pressure profiles calculated from this equation and those obtained from radiosonde observations at Tateno, Japan is consistent within 0.2 % below 3 km altitude. But the temperature dependency of the CO2 density is 0.25 %/°C near the surface. Moreover, the CO2 concentration is often evaluated by the mixing ratio. Because the air density is related by the ideal gas law, the mixing ratio is also related by the atmospheric temperature. Therefore, the temperature affects not only accuracy of CO2 concentration but the CO2 mixing ratio. In this paper, some experimental results of the simultaneous measurement of atmospheric temperature profiles and CO2 mixing ratio profiles are reported from 0.4 to 2.5 km altitude using the three-wavelength 1.6 μm DIAL system. Temperature profiles of CO2 DIAL measurement were sometimes different from those of objective analysis below 1.5 km altitude. These differences are considered to be due to regionality at the lidar site. The temperature difference of 5.0 °C corresponds to a CO2 mixing ratio difference of 8.0 ppm at 500 m altitude. This cannot be ignored in estimates of regional sources and sinks of CO2. This three-wavelength CO2 DIAL technique can estimate accurately temporal behavior of CO2 mixing ratio profiles in the lower atmosphere

  3. Trapping of cis-2-butene-1,4-dial to measure furan metabolism in human liver microsomes by cytochrome P450 enzymes.

    Furan is a liver toxicant and carcinogen in rodents. It is classified as a possible human carcinogen, but the human health effects of furan exposure remain unknown. The oxidation of furan by cytochrome P450 (P450) enzymes is necessary for furan toxicity. The product of this reaction is the reactive α,β-unsaturated dialdehyde, cis-2-butene-1,4-dial (BDA). To determine whether human liver microsomes metabolize furan to BDA, a liquid chromatography/tandem mass spectrometry method was developed to detect and quantify BDA by trapping this reactive metabolite with N-acetyl-l-cysteine (NAC) and N-acetyl-l-lysine (NAL). Reaction of NAC and NAL with BDA generates N-acetyl-S-[1-(5-acetylamino-5-carboxypentyl)-1H-pyrrol-3-yl]-l-cysteine (NAC-BDA-NAL). Formation of NAC-BDA-NAL was quantified in 21 different human liver microsomal preparations. The levels of metabolism were comparable to that observed in F-344 rat and B6C3F1 mouse liver microsomes, two species known to be sensitive to furan-induced toxicity. Studies with recombinant human liver P450s indicated that CYP2E1 is the most active human liver furan oxidase. The activity of CYP2E1 as measured by p-nitrophenol hydroxylase activity was correlated to the extent of NAC-BDA-NAL formation in human liver microsomes. The formation of NAC-BDA-NAL was blocked by CYP2E1 inhibitors but not other P450 inhibitors. These results suggest that humans are capable of oxidizing furan to its toxic metabolite, BDA, at rates comparable to those of species sensitive to furan exposure. Therefore, humans may be susceptible to furan's toxic effects.

  4. Evaluation of internal alpha-particle radiation exposure and subsequent fertility among a cohort of women formerly employed in the radium dial industry

    This study examined the effect of internal exposure to α-particle radiation on subsequent fertility among women employed in radium dial industry prior to 1930, when appreciable amounts of radium were often ingested through the practice of pointing the paint brush with the lips. The analysis was limited to women for whom a radium body burden measurement had been obtained and who were married prior to age 45 (n = 603). Internal radiation dose to the ovary was calculated based on initial intakes of radium-226 and radium-228, average ovarian mass, number and energy of α particles emitted, fraction of energy absorbed within the ovary, effective retention integrals and estimated photon irradiation. Time between marriage and pregnancy, number of pregnancies and number of live births served as surrogates for fertility. Radiation appeared to have no effect on fertility at estimated cumulative ovarian dose equivalents below 5 Sv; above this dose, however, statistically significant declines in both number of pregnancies and live births were observed. These trends persisted after multivariable adjustment for potential confounding variables and after exclusion of subjects contributing a potential classification or selection bias to the study. Additionally, the high-dose group experienced fewer live births than would have been expected based on population rates. There were no differences in time to first pregnancy between high- and low-dose groups. These results are consistent with earlier studies of γ-ray exposures and suggest that exposure to high doses of radiation from internally deposited radium reduces fertility rather than inducing sterility. 42 refs., 5 tabs

Objetivamos com isso, demonstrar o entrelaçamento dialogal composto no desenvolvimento da chamada doutrina do pecado original em ambos os autores. Isto é, como o desdobramento da antropologia kierkegaardiana problematizou os fundamentos da teologia sistemática, sobretudo, na questão da harmatiologia, e, como esta mesma problematização, foi capaz de padronizar o modus operandi que determinou a elaboração feita por Tillich sobre o mesmo assunto. Obviamente, que, no decorrer dessa investigação, não se pretendeu “desqualificar” ou “eliminar” a originalidade dos autores, nem tampouco transformar seus argumentos em uma espécie de amálgama conceitual. Assim, antes de uma suposta crítica de ter se proposto uma “fusão arbitrária de ideias”, buscamos, mais uma vez apontar soluções de dialéticas e centros comuns, que apontem para aqueles elementos de convergência, aonde de fato, o diálogo é possível.

    Full Text Available Os objetivos deste trabalho foram obter informações dos componentes de médias de populações de cajueiro (Anacardium occidentale L., por meio de análise dialélica parcial, e verificar o potencial per se de dois grupos distintos de parentais: um, constituído por clones comerciais de cajueiro-anão-precoce (CCP06, CCP76, CCP09 e CCP1001, e o outro, por matrizes de cajueiro comum (CP07, CP12, CP77, CP96 e BTON, e a heterose em suas respectivas combinações híbridas. Utilizou-se o delineamento experimental de blocos casualizados, com quatro repetições. Os caracteres avaliados foram altura da planta, diâmetro da copa, número da castanhas por planta, produtividade de castanhas, peso médio da castanha, peso médio da amêndoa e relação peso da amêndoa/peso da castanha. Constatou-se que os efeitos de parentais e heterose são importantes componentes das médias das populações em estudo, em relação a todos os caracteres. Entre os componentes heteróticos, a heterose média apresentou-se como o mais expressivo, indicando presença de dominância e considerável divergência genética entre os dois grupos. Apenas em relação aos caracteres número de castanhas e produtividade a capacidade específica de combinação foi significativa. As combinações híbridas CCP76 x CP07, CCP09 x BTON e CCP09 x CP77 são as mais promissoras, sendo indicadas para formação de populações-base para programas de melhoramento do cajueiro.

    Full Text Available Este artigo apresenta resultados parciais de nossa pesquisa de doutoramento de cunho etnográfico. Nela, investigamos o processo de formação continuada do professor de ensino médio, da rede pública, que adota o gênero discursivo conto como objeto de estudo em seu projeto de trabalho docente. O texto literário em foco é analisado sob a ótica da Linguística Aplicada e da Teoria Sociológica da Linguagem, revelando os vários movimentos dialógicos na dinâmica da interação verbal. Com efeito, compreender o diálogo pressupõe observar essas formas e essa recepção, as quais, na medida em que assumem uma função na língua, podem influenciar de maneira reguladora, estimulante ou inibidora, sobre o desenvolvimento das propensões à apreensão apreciativa, cujo campo de ação é justamente definido pela interação dinâmica das duas dimensões inseridas no contexto narrativo: o discurso a transmitir e aquele que serve para transmiti-lo.This article consists of a partial report of our doctoral research, within an ethnographic approach. We investigated the process of continuing education of high school teachers, from the public school system, who adopt the short story genre as their study subject in their teaching project. The literary text is analyzed based on Applied Linguistics and the Sociological Theory of Language, revealing the several dialogic movements in the dynamics of verbal interaction. Understanding the dialogue implies observing these forms and how they are perceived, and as they take on a role in language, they may influence in a regulatory, stimulating or inhibiting manner, the development of susceptibility to appreciative apprehension, whose field of action is precisely defined by the dynamic interaction of the two dimensions involved in the narrative context: the discourse to be transmitted and the channel used to transmit it.

    Full Text Available In this paper we analyze the articles published by Argentinean physician Juan Larzarte in the magazine Estudios in the 1930s. This took place within a publishing policy aimed at overcoming the exclusion of discourses opposing the established social order. The discourse practices we explore were dialogic while focusing on neo-Malthusian and eugenic propositions and the historical causes of a gendered social relations structuring a double sexual morals. Lazarte used several forms of intertextuality and suggested the compatibility of seemingly opposed approaches without getting round the differences and avoiding debates in dichotomic terms. These practices allowed the strategic use of eugenic rhetoric within the neo-Malthusian proposition aimed at the human species to reach a state of good living. As he did not consider history from an ideology of progress, and insisted on taking into account the different facets of any issue (biological, economic and cultural, Lazarte’s discourse in Estudios contributed to configure a world defying the assumptions of a deterministic biopower, thus becoming a destabilizing power regarding the sexual and social order.En este trabajo analizamos los artículos del médico argentino Juan Lazarte publicados en la revista Estudios en los años 30 del siglo XX. Este hecho se produjo en el marco de una política editorial que pretendía superar la exclusión a que eran sometidos los discursos de oposición al orden social establecido. La práctica discursiva analizada se desarrolló sobre una dialógica en torno a las propuestas neomaltusianas y eugenésicas y a las causas históricas de unas relaciones sociales generizadas que estructuraban una doble moral sexual. Lazarte usó diversas formas de intertextualidad y señaló la compatibilidad de planteamientos que se mostraban opuestos en apariencia, sin obviar las diferencias, evitando los debates en términos dicotómicos.

The terminologies and the techniques then used are explained as well as the various reasons (moral, theological, aesthetic, decorous, and others for undertaking that type of work, which is assumed as the precursor of the 19th century «scientific restoration». «Renovation» criteria, iconoclast and iconofylic practice related to this «utilitarian restoration» are discussed herein and important figures of Portuguese painting such as Francisco Venegas, Diogo Teixeira, André Reinoso, António Pereira Ravasco, Francisco Vieira Lusitano, amongst others, were also «painters-restorers» within those existing concepts. It is further reminded that to be a «painter-restorer», always in the perspective of an artistic «re-creation», was a motive for added pride for artists such as Pietro Guarienti,Vieira Lusitano, Pereira Pegado or Inácio Coelho Valente.

En lo referido a la primera cuestión, se analiza la peculiaridad de la dialéctica krausiana mostrando el esfuerzo que este autor realiza por ablandar las antinomias del esquema dialéctico, desconfiando siempre de la síntesis y proponiendo una dialéctica dual de la complementariedad El recorrido realizado incluye consideraciones relativas a la filosofía del derecho y la dialéctica en Krause, Hegel y Marx. En lo referido al lugar de las mujeres, Krause pensaba que si el Estado debía serlo de un pueblo organizado democráticamente, era preciso partir de una reestructuración de la familia. Desde su punto de vista el Estado provenía de la familia, de allí su esfuerzo por reformular su estructura sobre nuevas bases: la educación en los valores de libertad e igualdad. A contrapelo de las ideas volcadas por Rousseau en el Emilio, Krause pensaba que era preciso educar a las mujeres para la libertad y la armonía con el varón, de modo tal que a partir de una familia así formada se llegara a la institución de un Estado orgánico que no fuera obstáculo para el desarrollo pleno de cada uno de los seres humanos. Para Krause las mujeres deberían ser empujadas a unirse a la Alianza de la Humanidad, el ideal libertario promulgado por el filósofo. En este credo sería educada Sofía, su hija primogénita.This paper works about the Krause's ideas both dialectics and women's place. On dialectics the author analyzes the peculiarity of Krausist dialectics showing the author's effort to conceive the antinomies of dialectics in a softer way.

    Full Text Available Les Faux-monnayeurs d’André Gide est un (anti-roman qui fait appel à un autre médium artistique amimétique – en l’occurrence la musique – afin de mettre en question la représentation de l’authenticité, du réel et de la subjectivité de l’écrivain. Édouard, le protagoniste romancier qui souhaite lui-même rédiger un roman intitulé Les Faux-monnayeurs, se trouve plongé dans une mise-en-abîme où le récit linéaire contrapuntique déjà complexe se colore d’ambiguïté narrative grâce à une polyphonie verticale : et ce, par le biais de l’axe paradigmatique, des récits emboîtés et de l’usage du discours indirect libre. Gide réalise, au moins en partie, le rêve d’Édouard paralysé par la page blanche : terminer l’œuvre de Bach, L’Art de la fugue, en littérature. C’est-à-dire, que d’un point de vue intermédial, Gide emploie une poétique de la fugue – style musical théoriquement interminable – afin de subvertir le genre romanesque. L’intermédialité rejoint l’interdisciplinarité et, en appliquant le théorème mathématique et philosophique de Kurt Gödel – son théorème de l’incomplétude –, la verticalité textuelle, synonyme de métarécit chez Gide, se déploie dans toute son éloquence et renforce davantage la thématique du « faux » et de la « copie » dans un roman contrefait. Fleeing Completeness or The Intermedial Metanarrative of Les Faux-monnayeurs André Gide’s Les Faux-monnayeurs is a (anti-novel that calls upon another amimetic artistic medium – music – in order to question the representation of authenticity, of the real, and of the novelist’s subjectivity. The novel’s protagonist, Édouard, wishes to write a novel entitled Les Faux-monnayeurs, and finds himself at the bottom of a mise-en-abîme where the already complex contrapuntal narrative becomes further ambiguous alongside examples of vertical polyphony: such as the paradigmatic axis, framed

    Full Text Available A metodologia dialética propõe um ensino de dupla mão (professor-aluno que provoque a aprendizagem por meio de tarefas contínuas dos sujeitos. Para isso, o professor assume o papel de mediador e dirige as diferentes atividades. Nesse contexto, a Fisiologia do Exercício é uma disciplina academicamente orientada que está inserida em um ambiente dinâmico, e a utilização de estratégias de ensino se faz necessária para otimizar a apropriação do conhecimento de forma ativa, além de contribuir para a maior autonomia dos estudantes universitários. Portanto, o objetivo do presente estudo foi o de utilizar diferentes estratégias de ensinagem por meio de atividades propostas aos alunos na disciplina de Fisiologia da Atividade Motora I da Escola de Educação Física e Esporte da Universidade de São Paulo e correlacionar o desempenho do aluno com a sua participação nessas atividades propostas. Nossos principais achados demonstram correlações significativas e positivas entre a presença nas aulas e o desempenho nas avaliações (p < 0,0001; r = 0,84, bem como entre a realização das atividades propostas e o desempenho nas avaliações (p < 0,0001; r = 0,69. Em conjunto, esses dados sugerem que a utilização de diferentes estratégias de ensinagem baseadas na metodologia dialética com a ativa participação dos alunos é essencial para um bom rendimento acadêmico, sendo altamente recomendada para o ensino da Fisiologia do Exercício.

    O objetivo é compreender como as condutas dos tutores, em atividades a distância, potencializam diálogo-problematizador e produção colaborativa em torno dos conteúdos curriculares. Problematizamos as condutas dos tutores nas atividades de estudo Fórum no ambiente virtual de um curso de formação de professores a distância da UAB/UFSM. Segundo pressupostos teórico-metodológicos da pesquisa-ação, a abordagem de procedimentos contou com aplicação de questionários tipo survey, observação participante e exploração da documentação do curso. A análise foi categorizada pelas condutas conectada e separada fundamentadas na teoria dos modos de saber e educação dialógica. Os resultados indicam que condutas conectada e separada dos tutores, nas atividades de estudo Fórum em ambientes virtuais, promovem diálogo-problematizador e produção colaborativa desde que os mesmos desenvolvam fluência nos conteúdos, no modelo pedagógico e nas tecnologias em rede. As conclusões pontuam que os princípios da teoria dos modos de saber na interface com a educação dialógica são basilares para potencializar a problematização conceitual e a produção colaborativa em torno dos conteúdos curriculares na educação a distância.

PROCEDIMENTOS METODOLÓGICOS: Estudo qualitativo, no qual foram realizadas 11 entrevistas semi-estruturadas com cirurgiões oncológicos especializados em tumores de cabeça e pescoço da cidade do Rio de Janeiro, RJ, entre 2000 e 2005. Os participantes foram selecionados por chain sampling e a interrupção do trabalho de campo obedeceu ao critério de saturação. Utilizando-se a técnica de análise de discurso, buscou-se identificar as premissas estruturantes do conceito de autonomia, que comporiam uma dialética discursiva no contexto dos pacientes que relutam em se submeter a cirurgias consideradas mutiladoras. ANÁLISE DOS RESULTADOS: Inicialmente, os cirurgiões exibiram assertivas padronizadas, centradas em conceitos deontológicos de autonomia. À medida que narravam suas experiências, foram observados auto-questionamentos que expunham contradições quanto ao conceito cotidiano de "ressecabilidade informada". Neste ponto os discursos padronizados se deixam permear por auto-questionamentos sobre a necessidade de um retorno ao equilíbrio existencial prejudicado pelo câncer. CONCLUSÕES: As narrativas expressaram demandas por uma "autonomia de equilíbrios" na forma de um semi-projeto não idealizável aprioristicamente, embora dependente de interações com o outro. Os resultados indicam a necessidade de reflexão perante o conceito de autonomia como premissa linear, categórica e individual que, embora superficialmente elaborada, têm governado as ações cotidianas.OBJETIVO: Comprender diferentes lógicas de autonomía presentes en los conflictos entre prescripciones quirúrgicas y expectativas de pacientes con diagnóstico de cáncer.

    Ana Paula Coelho Figueira Freire

    Full Text Available INTRODUÇÃO: A doença renal crônica (DRC é decorrente de uma lesão renal e perda progressiva e irreversível da função dos rins. A hemodiálise substitui parcialmente essa função, com o objetivo de corrigir as alterações metabólicas na DRC. Para acompanhar a adequação da diálise, é determinado o Kt/V - índice de depuração da ureia por sessão de hemodiálise. O exercício físico de moderada intensidade tem se mostrado de fundamental importância para melhorar os efeitos adversos ao tratamento dialítico. OBJETIVOS: Avaliar o Kt/V em indivíduos com DRC submetidos ao exercício físico isotônico de baixa intensidade durante a hemodiálise. MATERIAIS E MÉTODOS: Analisados dados de 15 voluntários de ambos os sexos, submetidos à hemodiálise três vezes por semana. Após duas horas do início da diálise, foi aplicado um protocolo de exercícios isotônicos de baixa intensidade de membros superiores e inferiores com duração de 30 minutos, por um período de três meses. Os valores do Kt/V foram comparados no período de três meses anteriores sem exercício e após três meses de exercício. RESULTADOS: A média dos valores do Kt/V nos três meses sem exercício foi de 1,13 ± 0,11 e após aplicação do programa de exercícios foi de 1,29 ± 0,12 (p < 0,05. CONCLUSÃO: O programa de exercício físico isotônico de baixa intensidade em pacientes com DRC, aplicados durante a sessão de diálise mostrou a melhora da eficiência dialítica.

    2000-01-01

    Full Text Available Vigotski, em seu "Manuscrito de 1929" afirma que a relação filogênese-ontogênese no desenvolvimento orgânico é distinta da mesma relação no desenvolvimento cultural: enquanto que o embrião humano se desenvolve sem interagir com o organismo adulto, o desenvolvimento cultural da criança só ocorre por meio da interação com o adulto, isto é, com o ser mais desenvolvido. Partindo dessa afirmação, o artigo analisa as relações entre a dialética em Vigotski e em Marx, apoiando-se na reflexão metodológica e epistemológica desenvolvida por Marx no texto em que afirmou que "a anatomia do homem é a chave da anatomia do macaco". O artigo conclui com a defesa da tese de que a psicologia vigotskiana fornece apoio a uma pedagogia que valorize a transmissão das formas mais desenvolvidas do saber objetivo produzido pela humanidade.

    Full Text Available RESUMO: Bakhtin analisou a poética de Dostoiévski não por meio de uma síntese parcial em função do discurso do escritor ou de uma de suas personagens, mas através do diálogo que deixaria de ser contingente para assumir um papel estrutural. Bakhtin, porém, não pôde demonstrarcomo a obra de Dostoiévski constituiria uma totalidade polifônica integral. Com o aporte da teoria crítica, procuraremos reaproximar a polifonia bakhtiniana da noção contraditória de totalidade por meio do método dialético. ABSTRACT: Bakhtin analyzed Dostoevsky’s poetics not by a partial synthesis in terms of the speech of the writer or one of his characters, but through the dialogue that would leave itscontingency to assume a structural role. However, Bakhtin could not demonstrate how Dostoevsky’s work would constitute an integral polyphonic totality. With the contribution from the critical theory, we will try to reapproach Bakhtin’s polyphony to the contradictorynotion of totality through the dialectical method.

In the light of concepts such as sharing of the sensitive, dialectal images, metamorphosis of artwork and cyberspace, developed by the theoreticians Jacques Rancière, Georges Didi-Huberman, André Malraux and Pierre Lévy, my intention is to question the potential interaction and production of senses exploited, or not, in museum spaces. O artigo põe em cena o diálogo estabelecido pela relação entre público jovem e museus, analisando a contemporaneidade do discurso museológico tradicional. À luz de conceitos como partilha do sensível, imagens dialéticas, metamorfose da obra de arte e ciberespaço, desenvolvidos respectivamente pelos teóricos André Malraux, Georges Didi-Huberman, Jacques Rancière e Pierre Lévy, pretende-se interrogar o potencial de interação e de produção de sentidos utilizado, ou não, pelo espaço museal.

    2014-12-01

    Full Text Available O artigo apresenta resultados de um estudo comparativo sobre aspectos da questão da técnica em obras de Theodor W. Adorno e José Ortega y Gasset, desdobrado em suas relações com o progresso, o domínio da natureza e a cultura de massas. Pretende com isso encontrar o tema da formação e seus impasses, problematizando-o mais uma vez. O cotejamento parte de comentário de Adorno sobre Ortega, segundo o qual este seria um crítico conservador da cultura, para então confrontar teoricamente os temas escolhidos. A análise da técnica em Adorno e em Ortega dá-se a partir da posição que cada um apresenta nos termos da condição humana, extraindo-se daí as consequências analíticas, mas também formativas, de cada autor: uma vinculada à perspectiva de que seria a técnica motor da existência e produção do supérfluo; outra, que a compreende no interior de uma dialética do esclarecimento.

Com esse intuito, determinou-se, por meio de cruzamento dialélicos, a capacidade geral (CGC e específica (CEC de combinação para resistência a Puccinia polysora de oito híbridos comerciais de milho em diferentes níveis de adubação fosfatada. Cultivaram-se 56 combinações híbridas (F1s e recíprocos e oito genitores em dois ambientes distintos quanto à disponibilidade de fósforo (baixo e alto P e avaliou-se a severidade de ataque da ferrugem polissora, de acordo com a área abaixo da curva de progresso da doença (AACPD. A análise de variância conjunta indicou que os híbridos diferiram significativamente (p<0,01 quanto à curva de progresso da ferrugem polissora, sinalizando a existência de variabilidade genética entre eles na resistência à incidência da doença. O maior valor do quadrado médio da CGC comparado a CEC evidenciou, nesses genitores, maior contribuição da ação gênica aditiva no controle da resistência à ferrugem polissora. As combinações híbridas recíprocas P30F53 x AG 8060 e TRUCK x BM 2202 apresentaram as maiores médias negativas de CEC, em ambientes de baixo e alto fósforo, respectivamente, e foram classificadas, assim, como promissoras para obtenção de resistência à ferrugem polissora.

    Full Text Available Em grande parte da literatura a escrita é vista como recurso de explicitação de idéias/conhecimento. Pouco, entretanto, se diz sobre seu papel na constituição destas. Contrapondo-se a essa tendência, propõe-se aqui que a escrita, entendida como processo de construção de sentido, possui importante potencial de constituição do conhecimento. Este potencial de construção depende essencialmente de negociações entre o autor e 'vozes' sociais com que dialoga ao escrever. A análise do processo de produção textual de universitários sugere que este se desenvolve no tempo, alternando momentos de estabilidade e variabilidade. Estes últimos se materializam no subprocesso de Revisão Local que, sugerimos, caracteriza-se por negociações dialógico-argumentativas. Propomos ser precisamente nessa argumentatividade inerente à escrita que reside seu potencial epistêmico (constitutivo do conhecimento.Many researchers see writing as a resource that allows the explicitation of ideas/knowledge. Few, however, have addressed its role in the constitution of ideas. We propose that writing (understood as a sense-making process has considerable potential in knowledge constitution. This potential depends on negotiations between the author and the social "voices" with which he/she dialogs during text production. An analysis of text production among university students suggests that the process develops over time, alternating between moments of stability and variability. These latter moments materialize in the sub-process of Local Revision, which we suggest is characterized by negotiations of a dialogic-argumentative nature. We propose that the epistemic potential of the writing process resides precisely in the argumentativity inherent to such negotiations.

  15. The lives of Mary Foote: painter and Jungian.

    Science.gov (United States)

    Trousdell, Richard

    2016-11-01

    Mary Foote (1872-1968) was a successful early twentieth century American artist who suddenly closed her New York studio in 1926 to go to Zurich to study with Jung. There she joined his 'Interpretation of Visions' seminars (1930-1934), which she recorded and edited. This work won Jung's praise and his friendship, but all too often Foote was seen merely as a secretary or background figure. Deirdre Bair's biography of Jung suggested that Foote's life and work deserved fuller study, if only to rebalance our view of Jung's early women followers. This paper takes up that work to ask how Foote's early life and career led to her important work in preserving and describing Jung's earliest attempts to apply his theories to clinical practice. © 2016, The Society of Analytical Psychology.

    Colours as dynamic as the metallic-like hues adorning the Japanese jewel beetle have never been captured on canvas before. Unlike, and unmatched by, the chemical pigments of the artist's palette, the effect is generated by layered microstructures that refract and reflect light to make colour visible. Exclusive to nature for millions of years, such jewel-like colouration is only now being introduced to art. Sustained scientific research into nature's iridescent multilayer reflectors has recently led to the development and manufacture of analogous synthetic structures, notably innovative light interference flakes. For the first time this novel technology offers artists the exciting, yet challenging, potential to accurately depict nature's iridescence. Mimicking the Japanese jewel beetle by using paints with embedded flakes, we demonstrate that the resulting painting, just like the model, displays iridescent colours that shift with minute variation of the angle of light and viewing.

  18. Painter and scribe: From model of mind to cognitive strategy.

    Science.gov (United States)

    MacKisack, Matthew

    2017-12-06

    Since antiquity the mind has been conceived to operate via images and words. Pre-scientific thinkers (and some scientific) who presented the mind as operating in such a way tended to i) bias one representational mode over the other, and ii) claim the dominance of the mode to be the case universally. The rise of empirical psychological science in the late 19th-century rehearses the word/image division of thought but makes universal statements - e.g., that recollection is a verbal process for everyone - untenable. Since then, the investigation of individual differences and case studies of imagery loss have shown rather that words and images present alternative cognitive "strategies" that individuals will be predisposed to employing - but which, should the necessity arise, can be relearned using the other representational mode. The following sketches out this historical shift in understanding, and concludes by inviting consideration of the wider context in which discussion of the relationships between 'images' and 'words' (as both internal and external forms of representation) must take place.

  19. The Absent Painter: Ideological Premises in Tacitus portraits

    Directory of Open Access Journals (Sweden)

    Juan Luis Conde

    2015-09-01

    Full Text Available An interpretation of René Magritte's series La condition humaine underlines its anti-realistic warning. On that analogical basis, an approach to three of Cornelius Tacitus' protraits of emperors is provided, namely those of Galba, Tiberius, and Augustus. A common feature in these personalities is their particular difficulty to be represented in the static and univocal way required by literary portrait. The paper analyzes the rhetorical and ideological devices used by the artist to tackle that goal. As a counterpart, a circularity in the appropriation of ideological legacies is suggested, according to which forms that were designed by writers to describe characters in their works have historically moulded social representations of personality

    Full Text Available Spirit, Freedom and Dialectic are frequently explained as if they were a whole. The spiritual movement, namely Freedom, is shown as a dialectical process. Apparently, there is no other solution when the Spirit is conceived as truth, as a plenitude that belongs to Spirit, but that it does not have and it must acquire. That's because dialectic is usually understood as a necessary consequence of the axiom: truth is interiority, and is therefore identity. And if this axiom were false?

    Full Text Available Este trabalho trata da relação entre métodos quantitativos e qualitativos nas ciências sociais em geral e na área da educação em particular. Começa focalizando a orientação positivista da Sociologia, assim como de outras ciências sociais em sua origem, mas rejeitando a identificação sumária entre métodos quantitativos e positivismo. Aborda, então, a querela metodológica, com destaque para três teses a respeito da relação entre métodos quantitativos e qualitativos: a da oposição ou incompatibilidade; a da complementaridade; e a da unidade. Esta última, como unidade na perspectiva da dialética marxista. Por fim, sugere que, em vez de nos inquirirmos sobre qual a competência metodológica de maior valor em absoluto, deveríamos perguntar-nos se e como diferentes competências metodológicas poderão articular-se no estudo de um determinado objeto ou problema social ou educacional.This paper deals with the relationship between quantitative and qualitative methods in the social sciences in general and in the area of education in particular. It starts by focusing on the positivistic orientation that sociology and other social sciences had in their origin, but rejects a simple identification of quantitative methods and positivism. It then discusses the methodological dispute, highlighting three theses on the relationship between quantitative and qualitative methods: the thesis of opposition or incompatibility, the thesis of complementariness and the thesis of unity. The latter is seen as a unity in the perspective of Marxist dialectics. The paper finally suggests that instead of wondering what is the methodological competence that has the highest absolute value, we should ask whether and in which way different methodological competences can be brought together in the study of a particular object or social or educational problem.

    Full Text Available OBJETIVOS: Procura-se analisar as atuais evidências empíricas e teóricas sobre o modo de operar nas intervenções comportamentais dialéticas. Procedeu-se igualmente à análise da eficácia dessa terapia no tratamento da bulimia nervosa e no transtorno da compulsão alimentar periódica. MÉTODO: Realizou-se uma revisão agregativa da literatura, recorrendo às palavras-chave "dialectical behavior therapy", "bulimia nervosa" e "binge eating disorder" nas bases de dados PsycInfo e MedLine e em livros da especialidade, sob o critério da atualidade e premência das publicações levantadas. RESULTADOS: A terapia comportamental dialética, inicialmente desenhada para o transtorno de personalidade borderline, tem-se estendido a outros transtornos do eixo I. Sua aplicação às perturbações alimentares sustentase num paradigma dialético com o recurso das estratégias comportamentais e cognitivas. Esse modelo permite aos pacientes uma regulação mais efetiva dos estados afetivos negativos, reduzindo a probabilidade da ocorrência de comportamentos bulímicos e de compulsão alimentar periódica. CONCLUSÃO: Embora escasseiem estudos sobre a sua eficácia, os resultados existentes parecem comprovar a eficácia da terapia comportamental dialética nas populações descritas.OBJECTIVES: Current theoretical and empirical evidences on how to operate in dialectical behavioral interventions were examined. The effectiveness of these interventions in the treatment of bulimia nervosa and binge eating disorder were analyzed too. METHOD: An aggregative literature review was made, using the keywords "dialectical behavior therapy", "bulimia nervosa" and "binge eating disorder", from the database PsycInfo and MedLine and from reference books, selecting the most representative and recent scientific texts about this psychotherapy model.

    The chief effects of absorbed radionuclides and external radiation are radiation osteitis, disturbed bone growth, myelofibrosis, and bone tumors. The lesions in part are dependent on localization and character of the radiation, in part on dose. Data on radium were derived from dial painters, radium chemists and those treated some years ago by oral or parenteral administration. (U.S.)

    Full Text Available En el presente ensayo los autores pretenden exponer consideraciones acerca del lugar y la presencia del positivismo, la dialéctica materialista y la fenomenología como enfoques del método científico, al mismo tiempo, identificar su valor para la investigación educativa. No se consideran estas tres orientaciones como las únicas, ni las más importantes, es solo que tienen un espacio considerable en las creencias de los investigadores y en el debate académico y pueden ser puentes para asumir ideas filosóficas novedosas. La reflexión se hace desde una perspectiva que entra a cavilar sobre la realidad latinoamericana y en la que se muestran argumentos básicos de la interacción entre la filosofía y el método científico. El trabajo ha sido desarrollado a partir de la consulta de una extensa bibliografía que incluye tesis de maestría y de opción al grado científico de Doctor y de escuchar las opiniones de varios estudiosos que toman como campo la educación. Desde perspectivas muy heterogéneas, las distintas corrientes del pensamiento social y filosófico de los últimos siglos han estado ligadas a la evolución del proceder científico de producir el conocimiento, por lo que reflexionar sobre ello ofrece la oportunidad de apropiarse de criterios que pueden ser útiles para los científicos. Estar en posesión de buenos argumentos filosóficos para justificar las acciones investigativas impacta de manera positiva la actividad científica. Through this essay authors intend to expose some considerations related to the place and presence of positivism, materialist dialectic and phenomenology as approaches of the scientific method, and at the same time to identify its value to the educative investigation. These three orientation lines are not considered as the only ones or the most important one. It is just that they have a considerable space in the researcher’s believes and in nowadays academic debate and they can be bridges to assume

MÉTODOS: Análise de dados do Ministério da Saúde do Brasil de 25.952 pacientes com idade superior a 18 anos, portadores de EFDR, que estavam em tratamento dialítico em abril de 1997. Foram registrados os casos de óbito que ocorreram entre abril de 1997 e julho de 2000. Modelos de Cox foram utilizados para estimar o risco relativo (RR da associação entre número de anos em tratamento dialítico e risco de morte. RESULTADOS: O risco de morte foi significantemente menor nos pacientes que estavam em diálise entre 3 e OBJECTIVE: To assess whether, in Brazil, the number of years on dialysis treatment in end-stage renal disease (ESRD patients, with and without diabetes mellitus, relates to mortality risk. METHODS: Analysis of data from the Ministry of Health of Brazil of 25.952 patients older than 18 years who were on dialytic treatment in April 1997. Death cases that occurred from April 1997 to July 2000 were recorded. Cox models were used to estimate the relative risk (RR of the association between years on dialysis and mortality risk. RESULTS: The mortality risk was significantly lower in patients on dialysis between 3 and <10 years as compared with 1 to <2 years (RR between 0.78 and 0.88. With adjustments for age and diabetes the effect of years on dialysis was reduced. In diabetics (n=2.952 the adjusted mortality risk showed a trend to decrease with more years on dialysis. CONCLUSIONS: In Brazil, the mortality risk for ESRD patients decreases with the increasing number of years on dialysis up to approximately 10 years. This finding can be partially explained by the lower mean age and prevalence of diabetes mellitus in patients with more years on dialysis treatment. The effect of years on dialysis on the mortality risk seems to be

    Full Text Available Tendo como sustentação, o interacionismo sujeito-objeto de Piaget no ensino-aprendizagem propiciado pela linha pedagógica predominante nos jogos de negócios dirigidos ao ensino de Administração, bem como a proposta de superação via interacionismo sujeito-social de Vygotsky, é que se estrutura o presente trabalho. Norteado pela dúvida sobre qual alternativa pedagógica incorporada à prática metodológica dos jogos de negócios permite avançar de um interacionismo sujeito-objeto para um interacionismo sujeito-social, busca-se como objetivo principal nesse ensaio, apresentar uma alternativa pedagógica para os jogos de negócios que avance para além da perspectiva interacionista piagetiana na direção do interacionismo vygotskyano. Nesse sentido a metodologia adotada constitui-se de uma pesquisa bibliográfica, que discorre inicialmente sobre as características das principais tendências pedagógicas, partindo da tradicional até a histórico-crítica. Na sequencia destaca-se que os jogos em si, apresentam desdobramentos relacionados as tendências humanista e cognitivista apoiando-se na valorização dos interesses e ritmos individuais. Explicando a diferença entre os modelos piagetiano e vygotskyano que possibilitaria uma superação interacionista, é apresentado um detalhamento dos processos avaliativos para os jogos de negócios dentro de uma proposta pedagógica com pano de fundo dialético que reforça a dimensão social do conhecimento a partir da perspectiva histórico-critica de Saviani. A partir da analise do processo ensino-aprendizagem, destacando as diferenças das contribuições de Piaget e Vygotsky, conclui-se que os jogos podem avançar ao propor critérios avaliativos objetivos que pressupõe tomada de consciência por meio da zona de desenvolvimento proximal, caracterizada pela distância entre o nível de desenvolvimento real do indivíduo e seu nível de desenvolvimento potencial.   Palavras-chave Pedagogia

    Resumen

    El tema es una reflexión sobre la epistemología y la tradición de los saberes turísticos y ociológicos desde la perspectiva de la hermenéutica dialéctica. Su objetivo consiste en aproximarnos a la configuración de un pensamiento latinoamericanista de estirpe analógica, orientada a esquivar las limitaciones objetivistas típicas del univocismo turisticológico y de las deficiencias subjetivistas propias de los estudios de la posmodernidad del tiempo libre. La metodología está basada en la perspectiva de la contradicción y el enfoque hermenéutico. El trabajo es una reflexión crítica sobre el estatuto específico del pensamiento turístico de la modernidad tardía, señalando de manera sucinta sus fortalezas y debilidades. Los principales hallazgos en la investigación son: la necesidad de un horizonte dialéctico, analógico e interpretacional del turismo, priorizando la dimensión epistémica y la relevancia de la tradiciónLa dialéctica del amo y el esclavo como clave interpretativa del teatro emergente en la dictadura uruguaya de los años 70 The master-slave dialectic as a key for understanding the emergent theatre during the Uruguayan dictatorship of the '70s

    Full Text Available Aristóteles y Freud, entre otros, apoyaron la idea de que el teatro, a través de la catarsis o la posibilidad de purgar deseos reprimidos, ocupa un lugar central en la vida social, especialmente cuando regímenes totalitarios suspenden las libertades fundamentales. Sin embargo, en el microsistema teatral emergente en el Uruguay de la dictadura aparece un héroe degradado, sometido a la violencia. ¿Cómo lograba el receptor su catarsis al observar a un anti-héroe que perpetuaba la realidad opresiva? La respuesta se encuentra en Hegel y su dialéctica del amo y el esclavo. Veremos cómo puede aplicarse esta hipótesis a dos ejemplos del microsistema mencionado.Aristotle and Freud, among others, supported the idea that drama plays a central role in social life, through catharsis or the possibility of purging repressed desires, particularly when totalitarian regimes suspend fundamental freedoms. However, in the theatrical microsystem emerging during the Uruguayan dictatorship (1973-1984, the kind of hero that arose was humiliated, subjected to violence. How did the spectator reach his/her catharsis by observing an anti-hero that perpetuated the country's reality on stage? The answer to this question lies in Hegel and his dialectic of master and slave. This paper shall look into the way in which this hypothesis can be applied to two examples of the microsystem mentioned above.

  10. 2-Micron Laser Transmitter for Coherent CO2 DIAL Measurement

    Singh, Upendra N.; Bai, Yingxin; Yu, Jirong

    2009-01-01

    Carbon dioxide (CO2) has been recognized as one of the most important greenhouse gases. It is essential for the study of global warming to accurately measure the CO2 concentration in the atmosphere and continuously record its variation. A high repetition rate, highly efficient, Q-switched 2-micron laser system as the transmitter of a coherent differential absorption lidar for CO2 measurement has been developed in NASA Langley Research Center. This laser system is capable of making a vertical profiling of CO2 from ground and column measurement of CO2 from air and space-borne platform. The transmitter is a master-slave laser system. The master laser operates in a single frequency, either on-line or off-line of a selected CO2 absorption line. The slave laser is a Q-switched ring-cavity Ho:YLF laser which is pumped by a Tm:fiber laser. The repetition rate can be adjusted from a few hundred Hz to 10 kHz. The injection seeding success rate is from 99.4% to 99.95%. For 1 kHz operation, the output pulse energy is 5.5mJ with the pulse length of 50 ns. The optical-to-optical efficiency is 39% when the pump power is 14.5W. A Ho:YLF laser operating in the range of 2.05 micrometers can be tuned over several characteristic lines of CO2 absorption. Experimentally, a diode pumped Ho:Tm:YLF laser has been successfully used as the transmitter of coherent differential absorption lidar for the measurement of CO2 with a repetition rate of 5 Hz and pulse energy of 75 mJ. For coherent detection, high repetition rate is required for speckle averaging to obtain highly precise measurements. However, a diode pumped Ho:Tm:YLF laser can not operate in high repetition rate due to the large heat loading and up-conversion. A Tm:fiber laser pumped Ho:YLF laser with low heat loading can operate in high repetition rate. A theoretical model has been established to simulate the performance of Tm:fiber laser pumped Ho:YLF lasers. For continuous wave (CW) operation, high pump intensity with small beam size is suitable for high efficiency. For Q-switched operation, the optimal energy extraction relies on the pump intensity, pump volume, and pump duration which is inversely proportion to the repetition rate. CW and Q-switched Ho:YLF lasers with different linear cavity configurations have been designed and demonstrated for a 30 W Tm:fiber pump laser. The CW Ho laser slope efficiency and optical-to-optical efficiencies reach 65% and 55%, respectively. The pulsed laser efficiency depends on the repetition rate. For 1 kHz operation, the optical-to-optical efficiency is 39% when the pump power is 14.5W. Currently, the injection seeding success rate is between 99.4% and 99.95%. After a ten thousand pulses, the standard deviation of the laser frequency jitter is about 3 MHz. It meets the requirements of highly precise CO2 concentration measurement. In conclusion, an injection seeded, high repetition rate, Q-switched Ho:YLF laser has been developed for a coherent CO2 differential absorption lidar. This master-slave laser system has high optical-to-optical efficiency and seeding success rate. It can potentially meet the requirements of the coherent detection of CO2 concentration by a differential absorption lidar technique.

    Full Text Available Trata-se de uma reflexão crítica acerca do capítulo VI do livro O Poder Simbólico de Pierre Bourdieu (1989, que se propõe a examinar as lutas simbólicas, inspirando-se, sobretudo, na sociologia da representação, cuja formulação clássica é de Durkheim. Toma de empréstimo desse mesmo autor, através de Bachelard, o seu racionalismo, que lhe permite efetuar a separação entre "classe teórica" e "classe real". Conforme o enfoque crítico do artigo, a conseqüência inevitável desse procedimento é a negação de todo e qualquer ontologismo e a resultante formalização do conhecimento.

    Full Text Available Uno de los numerosos desafíos para los críticos a la hora de interpretar la complejidad de La Celestina ha sido y sigue siendo el problema de su clasificación genérica. el título original  –primero  Comedia  y  en  la  segunda  redacción Tragicomedia  de  Calisto  y melibea–, se refiere según la teoría actual de los géneros a una obra dramática. Sin embargo, como apunta ĺñigo Ruiz arzálluz (La Celestina 2000: xCii–xCiii, a finales de la edad Media en Castilla los términos ‘comedia’ y ‘tragedia’ se alejaron del concepto clásico y «no implicaban necesariamente una estructura dramática», sino que se referían al aspecto temático y significaban «toda obra literaria […] que empezara mal y terminara bien», en el caso de comedia, o aquella «en la que el principio era alegre y el final triste», para la tragedia. De hecho, aunque la obra de Rojas está escrita en forma de diálogos y sería de esperar que todo en ella fuera activo, es obvio que en los diálogos y aún más en los monólogos la función dramática es a menudo superada por la función narrativa. es significativa en este sentido la hesitación inicial de Menéndez Pelayo, quien, a pesar del carácter supuestamente dramático de la La Celestina afirma que no se puede prescindir de ella en una historia de la novela y la incluye como «novela dialogada» en su obra Orígenes de la novela en España (Menéndez Pelayo 1961: cap. x. Dejando de lado las argumentaciones que tratan de encasillar La Celestina sea en el drama sea en la novela, parece mucho más justificado centrar la atención no en la definición genérica en el sentido de formas o estructuras (tema tratado prácticamente por todos los que abordaron el estudio de esta obra, desde Menéndez Pelayo (1943, Gilman (1956, Lida de Malkiel (1962, Whinnom (1993, Deyermond  (1980,  Severin  (1989,  etc.,  sino  en  las  funciones  narrativas  y/o dramáticas y sus respectivos procedimientos que intervienen en la construcción del texto.  Javier  Huerta  Calvo  (2000,  por  ejemplo,  realza  precisametne  su  carácter independiente en cuanto a cualquier técnica o preceptiva –otra originalidad más de esta obra– vinculándola a las formas más avanzadas de la dramaturgia contemporánea (p. ej. de valle-inclán en las que «los condicionamientos de género se han mitigado o han desaparecido y la estructura dramática ha ganado en flexibilidad, dejándose contaminar incluso por el ritmo de la narración».

    As part of a large-scale epidemiological study, occupational isocyanate exposure was assessed in spray-painting environments. The aim was to assess which compounds contribute to isocyanate exposure in car body repair shops and industrial painting companies, and to identify tasks with high risk of isocyanate exposure. Mainly personal task-based samples (n = 566) were collected from 24 car body repair shops and five industrial painting companies using impingers with DBA in toluene. Samples were analysed by LC-MS for isocyanate monomers, oligomers and products of thermal degradation. From the 23 analysed compounds, 20 were detected. Exploratory factor analysis resulted in a HDI, TDI and MDI factor with the thermal degradation products divided over the TDI and MDI factors. The HDI factor mainly consisted of HDI oligomers and was dominant in frequency and exposure levels in both industries. Spray painting of PU lacquers resulted in the highest exposures for the HDI factor (car body repair shops than in industrial painting companies. Exposure levels were low (car body repair shops (

  20. Non-invasive techniques for revealing the palette of the Romantic painter Francesco Hayez

    2017-04-01

    This paper describes the first systematic analysis of the palette of Francesco Hayez, one of the most outstanding artists of European Romanticism, whose painting technique has never been extensively investigated despite the plethora of artistic studies. He lived in a particular moment in the history of painting, as in the first half of the 19th century many synthetic pigments were available, also in tin tubes, but traditional materials were still used. Sixteen paintings on canvas and on panels, created between 1823 and 1868, were analyzed in situ through non-invasive techniques (infrared reflectography and infrared reflection spectroscopy). Imaging investigation provided clues on painting technique, revealing some cases of pentimenti and underdrawings. A preliminary survey was carried out on a hundred pure pigments used up to the 19th century and on new synthetic colours, in order to attain reference spectra for the interpretation of painting spectra. The portable infrared instrument provided insight into Hayez's painting materials, identifying barite, ivory black, lead-tin yellow, Naples yellow, ochres, Prussian blue, and white lead. The pigments were often blended, to obtain a unique fabric appearance or to attain cold shades. The results pointed to a siccative oil as a binder, mixed with white lead so that it could act as a catalyzer in polymerization reactions, and in some cases with a proteinaceous binder and resins. The preparation was made with gypsum and white lead mixed with a siccative oil. The results showed that the artist used a typical traditional palette, throughout his career, in order to lead to brilliant colours and with long-term stability. Anyway, the possible presence of cobalt blue in a few paintings suggests that Hayez had probably started testing the new colours, since the second decade of 19th century.

  1. A Painter's View of the Cosmos In the Twenty-first Century

    I am an ecosystem artist who uses paint to bring nature's “invisible forces” into view. My eco-sensitive palette recreates the push-pull forces that shape and mold all things. As a result, I create microscopic and telescopic views of earth and places scattered throughout our universe. Self-similarity led me to realize that if I want my mind to wonder into the far reaches of the universe, I must draw closer to nature. I show how space looks and appears and, more importantly, how it moves. My speed element palette is a portal through which I peer into the universe at scales great and small using paint as my lens. Microscopes, telescopes, the Internet, and even eyeglasses are portals through which technology affords us the ability to see that which is unseen to the unaided eye. Rather than see the world and then paint, the opposite is true for me. My work is revelatory, not representational and, as such, seeks similar occurrences in nature. Just as a planet's surface is a visual record of past events, so too do speed element experiments reveal traces of the past. It would be more accurate to call a painting that comes to rest a “painted.” It is video that captures images that eluded capture by the canvas and could more accurately be called a “painting. ” Simply put, I manipulate space, time, and matter—and the matter is never just paint.

    The aim of the presentation is to show results of the collaboration between the Croatian Conservation Institute (CCI) and the Laboratory for Ion Beam Interactions of the Rudjer Boskovic Institute (RBI) established within the present CRP. CCI is the central Croatian institution for conservation and restoration of cultural heritage objects. Prior to restoration/conservation CCI performs scientific analysis of an object, primarily to enable selection of the best strategy for its restoration/conservation. In many occasions such analysis is also helpful to resolve issues such as clarification of authenticity and/or authorship of an object. CCI has its analytical laboratory which is fully dedicated to the analysis of cultural heritage and art objects. CCI analytical laboratory is equipped with various microscopy techniques, photography methods, portable X-ray Fluorescence Spectrometer (XRF) and X-ray radiography instrumentation. Access to complementary microanalytical techniques like Raman Spectroscopy or Ion Beam Analytical (IBA) techniques is provided through already long and successful collaboration with RBI. The RBI Laboratory for Ion Beam Interactions provides complementary analysis of layered microsamples by using IBA techniques, such as Particle Induced X-ray Emission (PIXE) and Rutherford Back-scattering (RBS), and for the miniature samples by using ion microprobe.

    Full Text Available Exposure to lead-containing dusts is a global public health concern. This work addresses an important issue of whether eco-friendly water-based paints reduce the exposure potential of auto-repainting workers to metals. With this aim, metal levels in automobile paints and worker metal exposure were measured using both solvent- and water-based paints. The levels of metals, and particularly Pb, Cr (total, Fe, and Cu, in solvent-based paints varied greatly among colors and brands. Lead concentrations ranged from below the detection limit (~0.25 μg/g to 107,928 μg/g (dry film across all samples. In water-based paints, the concentrations of Pb and Cr (total were generally two to three orders of magnitude lower, but the concentrations of Al and Cu exceeded those in some solvent-based paints. The personal short-term exposure of workers who applied water-based paints of popular colors, such as black and white, were generally low, with Pb levels of less than <4 µg/m3 and Cr (total levels of less than 1 µg/m3. Conversely, mean short-term exposure to Pb during the painting of a yellow cab using solvent-based paints were 2028 µg/m3, which was ~14 times the Taiwan short-term permissible exposure limit, while the mean level of exposure to Cr (total was 290 µg/m3, which was well below the exposure limit. This study demonstrates that water-based paints reduce the exposure potential to lead, and highlights the importance of source control in limiting the toxic metals in paints.

  8. Ivan Rančić: A forgotten painter of flowers and landscapes

    Full Text Available Ivan Rančić was born in the Kraljevo village, in eastern Serbia to a family of farmers on 19th, February, 1906. Very little data about him has been preserved, therefore, this paper is an attempt to make a reconstruction of his life and work. He attended primary school in his birth place, lower secondary school he finished in Knjazevac and Military Academy in Belgrade. After completing the National Academy in 1934, he was sent to Zagreb where he got his first post. He lived there with his wife and his son until the capitulation of the country in 1941. A few months after the collapse of the country, he was arrested and sent to Ljubljana and three months later to a concentration camp in Austria. He spent about fifteen months in that camp in during which time he intensively studied painting. He fled from the camp to Switzerland and stayed there until his death in 1987. According to some letters he sent to his wife in Nis, some of his paintings he created during his time in the camp, ne took to Switzerland where he eventually sold them. He did the toughest jobs there in order to survive and painted extensively. After World War II he graduated from the School of Fine Arts in Lausanne. Later on he had two exhibitions at the New Gallery of Modern Art. Ivan Rančić came a long way from an unknown beginner to a respected prominent artist. He left behind about 350 works, many of which he sold during his life, mainly landscapes and still life in oil, watercolor and pastel. He was neither concerned about styles and trends nor did he believe in the old and the new. If he came to a certain specific manner of painting, it is because at one point it was imposed on him as the only proper way of expression. The analysis of Rančić's paintings leads to the conclusion that his creation had gone through four phases. The first one (started in the concentration camp in Austria during which he painted still lifes without full sketches, previous studies, and the use of linear perspective. This phase is characterized by the use of dark colors. This phase is followed by the one in which he painted flowers and vases with flowers. A considerable number of paintings from this period has been preserved, many of which were done in oil on canvas, while most of which were painted in oil on plywood or cardboard. A number of these paintings was painted in watercolor on paper. In the colorist sense, this stage was very different from the previous one. The next was the stage in which he painted landscapes. Some of his landscapes, mostly the ones which were painted using the combination of watercolor and pastel have a transparent atmosphere, bright and flickering light. The fourth stage was, in fact, a synthesis of all previous stages of development in which Rančić attempted to alleviate some of his artistic shortcomings. Almost all of his paintings were signed but none were dated , so t will be very difficult to determine the time of their creation. Ivan Rančić is a rare example of an artist who came a long way from realism through impressionism to expressionism. Rančić, as a man, wanted and succeeded to remain completely anonymous to us. As an artist, he could not prevent a number of Swiss art lovers from recognizing a talented artist in him. His painting represents the last page of a yet unwritten history of Serbian painting of the twentieth century. He died in a nursing home in Korbirijer on 26, January, 1987. The urn with his ashes is being kept in that place.

    Brain as the seat of behavior is acknowledged from the times of Charaka, however where neurology ends and philosophy begins remains an enigma. It is certainly every neurologist's observation that there is loss of function either region based or domain based in progressive diseases of the nervous system making it the seat of all useful activities. However, there are references to occurrence of new skills seen during various illnesses causing progressive cognitive dysfunction. This serves as a pharmaco-sparing agent in behavior management and therefore serves as a rehabilitatory tool. However, its pathomechanism is not clear. Two patients comprising one male and one female who were being evaluated for progressive cognitive dysfunction and were found to have interesting creative skills and are being described. The first patient is a case of young onset behavioral variant frontotemporal dementia and the second patient is a case of neurosarcoidosis. The emergence of these skills could be due to disinhibition of some of the innate skills of the patients during degeneration or establishment of new data linking circuits with creative potential during attempted repair.

    Two-mutation carcinogenesis models of mice injected with Pu-239 and Ra-226 have been derived as an extension of previous modellings of beagle dogs injected with Pu-239 and Ra-226 and dial painters that ingested radium. In all cases the data could be fitted adequately using no more than five free model parameters. Apart from three parameters for the background, these include two dose-related parameters: a linear mutation coefficient that is equal in both mutational steps and a usually non-zero cell-killing coefficient in the second mutational step. After a simple scaling the animal models compare reasonably well with each other and with the model for the radium dial painters. From the toxicity ratio of beagle models for Pu-239 and Ra-226, together with the human model for Ra-226, an approximate model for the exposure of humans to Pu-239 has been constructed. Relative risk calculations with this approximate model are in good agreement with epidemiological findings for the plutonium-exposed Mayak workers. This promising result may indicate new possibilities for estimating risks for humans from animal experiments. (orig.)

  18. Synchronized dial-a-ride transportation of disabled passengers at airports

    DEFF Research Database (Denmark)

    Reinhardt, Line Blander; Clausen, Tommy; Pisinger, David

    2013-01-01

    The largest airports have a daily average throughput of more than 500 passengers with reduced mobility. The problem of transporting these passengers is in some cases a multi-modal transportation problem with synchronization constraints. A description of the problem together with a mathematical...... model is presented. The objective is to schedule as many of the passengers as possible, while ensuring a smooth transport with short waiting times. A simulated annealing based heuristic for solving the problem is presented. The algorithm makes use of an abstract representation of a candidate solution...

    Full Text Available Given the lack of research on this subject produced in Romance Languages, the author Given the lack of research on this subject produced in Romance Languages, the author tries to find a possible meeting point between the philosophical systems of Fichte and Sartre in order to understand better their contributions to this theme. Disregarding a possible approach to these two authors through a receptive textual criticism of the former in the work of the latter, it is possible to identify points of convergence and coincidence between them. Subsequently, the paper focuses on the subject of freedom, firstly, from the Transcendence of the Ego and Being and Nothingness, and secondly, from the Foundations of the Entire Science of Knowledge and Nova Method. In this way, freedom is perceived as the cornerstone for both systems of thought and the bridge that shortens the distance between the Fichtean self and nonself and the Sartrean being-in-itself and being-for-itself.

Sin embargo, la comprensión del concepto de racionalidad lleva a la interpretación moderna del mundo y debido a la conexión entre teoría de la racionalidad y de la modernidad se puede construir una teoría de la sociedad. Para el análisis se recuperan aquellos autores que han enfatizado la ponencia crítica de la razón, para cuestionar como plantea Habermas las aporías de la razón y reivindicar el proyecto emancipador de la propia razón, rescatar el mundo de la vida de la racionalidad instrumental para crear la posibilidad de una sociedad verdaderamente humana.

    1986-01-01

    Personal habits and biological characteristics of 42 female Illinois radium workers first employed during the 1920s were analyzed in relationship to radium loss in late adult life. The 42 women met the criteria that they first were examined between 1957 and 1969 and are no longer employed, have had two or more radium body-burden measurements by gamma spectroscopy, 10-year minimum interval exists between initial and final measurements, and exhibit a RaC body burden in 1970 or later of ≥.137 kBQ. High radium body burdens are associated with decreased rates of radium elimination, as previously described. However, the most powerful predictor was coffee/tea consumption, increased consumption being associated with increased rates of radium elimination and explaining ∼35% of the variance. The effect persisted after deletion of smokers and subjects with x-ray evidence of bone damage. Weight/height ratios were positively associated with radium excretion. Individuals smoking cigarettes throughout the study period had significantly low rates of elimination of radium, similar to subjects with x-ray evidence of significant radiation-induced bone damage. Both smokers and subjects with x-ray evidence of radiation damage to bone had low weight/height ratios, suggesting that biological promoters of radiation damage to bone may exist. Rates of radium elimination were significantly associated with (linear) bone density, demonstrating that rates of loss of radium cannot be assumed to be independent of adult or postmenopausal bone density losses. Number of children and age of menopause did not have demonstrable effects on radium elimination. 9 refs., 2 figs., 7 tabs

    This paper sets out to review the dilemma of citizenship Wollstonecraft raised in A Vindication of the Rights of Women, published in 1792. I argue that this dilemma falls into the same trap feminist theory does by proposing two different (and opposed models of feminism: equality and difference. In this paper I suggest that the two are in fact the same paradox, which in turn refers to the equality-difference binarism that operates by structuring the liberal-patriarchal debate on equity in the social contract. Feminism must climb out of this trap in order to offer a new concept of citizenship in which women do not have to decide between equality and difference, or between justice and care.

    Full Text Available Seasonality was a stronger influence in the ichthyoplankton assemblages around the Saint Peter and Saint Paul Archipelago (SPSPA than distance from the islands. Plastic debris were ubiquitous and although it presented diel trends, no other spatiotemporal patterns was showed. Larval Oxyporhamphus micropterus was the most important taxa (29.37% of the total catch, followed by Ceratoscopelus warmingii and Entomacrodus vomerianus. Exocoetidae eggs represented 41.01%. Mesopelagic fish larvae dominated the community. Myctophidae had the highest species richness (15. Four larval fish assemblages occured: (1 nighttime demersal/bathydemersal (Anguillidae, Congridae; (2 daytime mesopelagic/bathypelagic/epipelagic (Myctophidae, Cyclothone acclinidens; (3 daytime epipelagic (Exocoetidae, Coryphaena hippurus, Thunnus albacares and (4 nighttime reef and demersal (Blennidae, Pomacentridae, Lutjanidae. The dry season (lower temperature, higher chlorophyll a and higher SW wind velocity influenced the first two assemblages. The rainy season (higher temperatures and lower NW wind velocity influenced the last two. Nighttime abundance of dominant species in the rainy season suggests diel vertical migration nearshore. Plastics were 2.12 times more abundant than the most abundant fish larvae. Comparable amounts of larvae and plastics in the water column increase the chances of interaction between these two compartments and might disturb the local marine food web and promote the transfer of microplastic from one habitat to another, especially when smaller taxa contaminated by ingested fragments are preyed by migratory animals such as marine birds and tuna. A study around the area concluded that at least a part of the plastic debris can have local source due to fishing activities. Small-scale oceanographic mechanisms such as the interaction between the topography and currents (SEC and EUC seem to be responsible for the retention of fish eggs, fish larvae and plastics around SPSPA.

Se estudos do verbal e do visual, separadamente, contam com longa e respeitável tradição em várias áreas do conhecimento e com estudos bastante expressivos e rigorosos na atualidade, também a condição verbo-visual da linguagem tem hoje um lugar privilegiado, não somente enquanto produção social, cultural e discursiva recorrente, mas, por isso mesmo, como objeto de estudos. Assim sendo, o objetivo aqui é focalizar alguns textos de diferentes gêneros, advindos de diferentes esferas, nos quais a articulação verbo-visual, tecida na instância de produção, funciona, deliberadamente, como projeto de construção de sentidos, de efeitos de sentido, quer lógicos, ideológicos, emocionais, estéticos ou de outra natureza, entretecidos por um diálogo face a face em que alteridades, ao se defrontarem, convocam memórias de sujeitos e de objetos, promovendo novas identidades.

Body contents of radium have been measured in 1916 of the dial workers and about one-half of the subjects in the other groups. Bone sarcomas, carcinomas of the paranasal sinuses and mastoids, and deterioration of skeletal tissue are still the only effects unequivocally attributable to internal radium. Excess leukemias have not been observed and other malignancies, if in excess, appear more likely to be related to external gamma radiation or radon than to internal radium. Positive correlations with radium burdens have been found for the incidence of benign exostoses among subjects exposed to radium before age 18 and for shortened latency of ocular cataracts. 26 references, 3 figures, 5 tables

    This study was conducted to determine the toxicity of injected {sup 226}Ra in immature dogs and to compare the results with those from studies of injected {sup 226}Ra in young adult dogs. An historic objective of these studies, initiated at the University of Utah and continued at ITRI, was to compare the results in dogs to the population of dial painters who ingested {sup 226}Ra as young adults. Age at the time of exposure is considered to be an important factor in dosimetry and risk of developing radiation-induced disease, particularly bone cancer. In summary, dogs injected with {sup 226}Ra when immature had increased occurrences of bone tumors in a dose-related fashion.

    Two-mutation carcinogenesis models of mice and rats injected with 239 Pu and 226 Ra have been derived extending previous modellings of beagle dogs injected with 239 Pu and 226 Ra and radium dial painters. In all cases statistically significant parameters could be derived fitting data from several research groups jointly. This also lead to similarly parametrized models for 239 Pu and 226 Ra for all species. For each data set not more than five free model parameters were needed to fit the data adequately. From the toxicity ratios of the animal models for 239 Pu and 226 Ra, together with the human model for 226 Ra, an approximate model for the exposure of humans to 239 Pu has been derived. Relative risk calculations with this approximate model are in good agreement with epidemiological findings for the plutonium-exposed Mayak workers. This promising result may indicate new possibilities for estimating risks for humans from animal experiments. (authors)

    This report provides risk estimates for various health effects of alpha radiation. Human and animal data have been used to characterize the shapes of dose-response relations and the effects of various modifying factors, but quantitative risk estimates are based solely on human data: for lung cancer, on miners in the Colorado plateau, Czechoslovakia, Sweden, Ontario and Newfoundland; for bone and head cancers, on radium dial painters and radium-injected patients. Slopes of dose-response relations for lung cancer show a tendency to decrease with increasing dose. Linear extrapolation is unlikely to underestimate the excess risk at low doses by more than a factor of l.5. Under the linear cell-killing model, our best estimate

  8. Bone sarcoma in humans induced by radium: A threshold response?

    International Nuclear Information System (INIS)

    Rowland, R.E.

    1996-01-01

    The radium 226 and radium 228 have induced malignancies in the skeleton (primarily bone sarcomas) of humans. They have also induced carcinomas in the paranasal sinuses and mastoid air cells. There is no evidence that any leukemias or any other solid cancers have been induced by internally deposited radium. This paper discuses a study conducted on the dial painter population. This study made a concerted effort to verify, for each of the measured radium cases, the published values of the skeletal dose and the initial intake of radium. These were derived from body content measurements made some 40 years after the radium intake. Corrections to the assumed radium retention function resulted in a considerable number of dose changes. These changes have changed the shape of the dose response function. It now appears that the induction of bone sarcomas is a threshold process

    Tooth breakage has been common among the 224 Ra patients, especially those injected as teenagers. The fracture of 1 or more teeth was reported by 26% (8/31) of boys and 23% (7/30) of girls injected with 224 Ra at 16-20 years of age. Combining results from all age groups, the incidence of tooth fractures increased significantly with dose (P=0.01). Unlike the normal loss of permanent teeth by periodontal disease, in which the entire tooth is lost, the tooth loss following 224 Ra injection was primarily from tooth resorption near the gum line causing the tooth crowns to break off easily. Eventually the tooth roots may either become incorporated into the jawbone or are resorbed and replaced with bone. These tooth fractures resembled those observed in the U.S. radium dial painters and in dogs injected with bone-seeking α-emitters. (orig.)

    Radium-induced intraocular neoplasia has not been reported in people, nor were the intraocular pigmentary changes observed in the beagles described in the dial painters or the radium 226 iatrogenic cases. However, Spiess (1969) has observed a 25% incidence of multiple pigmented naevi in the iris of the radium 224 German cases and Stefani, Spiess and Mays (1986) have noted an abnormal incidence of cataracts in this same group of patients. The reasons for the absence of the much less severe radium-induced eye changes in man as compared to the dog has not been determined. Reference is also made to the authors radium 226 rodent studies with mouse strain onychomys leucogaster. (author)

    One hundred and sixty dogs given single intravenous injections of 226 Ra citrate at age 17 +/- 2 months (116) or a non-radioactive solution (44 controls) were part of a 30 year long experiment to determine the relative radiotoxicity of injected 226 Ra and 239 Pu. The authors report a preliminary summary of the results of the 226 Ra study. Skeletal development of the beagles used in this study is analogous to a young adult human, simulating that of a young adult radium dial painter or occupationally exposed person. Injected dosage of 226 Ra, average skeletal dose, and number of dogs and dogs developing bone sarcomas in each group are presented. The lowest nominal injected activity was 0.007 μCi/kg. Each of the 8 dosage levels contained about 12 dogs, except for 23 dogs at 0.06 μCi/kg and 25 dogs at 0.02 μCi/kg

    The overall objective of this research program is to predict the risk to humans following exposure to 239 Pu. The beagle was originally selected for this program because it is relatively long-lived and has skeletal functions and structure analogous to young adults humans, simulating that of a young adult radium dial painter or occupationally exposed person. Young adult (17 month-old) beagles from the moderately inbred colony at the University of Utah were administered one intravenous injection of 239 Pu (0.0007-2.88 μCi/kg in 238 dogs) or 226 Ra (0.007-10.4 μCi/kg in 119 dogs), and compared to appropriate age-matched control beagles. All beagles have been and are being observed clinically throughout their expected 12 to 15 year post-injection lifespan. A thorough clinical and post-mortem survey is conducted to determine causes of death or lesions at death. The clinical findings are being encoded using SNOMED terminology and entered into a computerized database. All beagles in the 226 Ra study are dead and the data are being analyzed and published. The shape of the curve for dose vs. bone tumor incidence is highly linear up to average skeletal doses of 2200 rads. In higher dose groups, the time to tumor appearance is decreased and skeletal tumors occur in almost all animals. The 226 Ra response is being compared with the 239 Pu response in beagles. This toxicity ratio will allow use of the bone tumor response in the radium dial painters to predict the toxicity of plutonium for bone tumor induction in man

    The beiwusheng huiguan (`Meeting hall of the Five Northern Dynasties') is a building complex from the Qing dynasty (1636-1912 ad) located in Wafangdian, near Ziyang, in the south of the Chinese Province of Shaanxi. Two of the preserved halls are richly decorated with wall paintings dated probably in 1848 ad and representing scenes of the `Romance of the Three Kingdoms' and Confucian moral tales. They are a rare example of well-preserved mural paintings of high artistic value inside civil buildings. The aims of this paper are the chemical characterization and localization of organic materials used as binders and colorants in the wall paintings. A multi-analytical approach, consisting in the combined use of gas chromatographic-mass spectrometric techniques (GC/MS and Py-GC/MS) and high-pressure liquid chromatography with diode array detector (HPLC-DAD), was chosen for these purposes. Proteinaceous materials (animal glue and egg), saccharide material (fruit tree gum) and a siccative oil were identified in different paint layers supplying invaluable information about the painting technique used. Moreover, the analyses of organic dyes allowed identifying indigo and gallic acid in more than one sample adding fundamental information about Chinese artists' techniques in mural paintings, missing from the previous studies. To shed light on the gilding technique, the distribution of the painting materials was achieved by means of synchrotron radiation Fourier transform infrared spectroscopy (SR micro-FTIR) and X-ray fluorescence (SR micro-XRF). The results obtained from the multi-analytical approach enabled us to determine the organic materials both binders and organic colorants used by Chinese artisans, highlighting the high technical level achieved in nineteenth century. The binding media and the organic colorants identified, as well as their distribution, allowed the discussion on the painting technique used by the artists of the Qing dynasty giving information for the first time about the decoration of Chinese civil buildings.

  17. Silesian Workshop of master painter 1486-87 in the light of studies on lead white by means of neutron activation analysis

    The article shows results of the analyses of the element vestiges in the specimens of lead white obtained by means of the instrumental neutron activation analysis (INAA). The paintings from Master Workshop 1487-87 were studied. The anonymous workshop was active in Silesia towards the end of 15th century and specialized in making immense altarpieces on commission as well as single votive and epitaph paintings. The purpose of the studies was predominantly to determine the kind of lead white used in the Master Workshop 1486-87. The results of the studies show that the workshop applied the so-called transalpine white. The whites in all the studied paintings resemble those coming from the fifteenth-century paintings of the Silesian School. These significantly differ from the whites of the Malopolska School. The results of the studies also give additional information on the origin and material applied not only in the Silesian painting art but also in that from Poland and Europe. Comparing the results of these analyses concerning the studied paintings constitutes the source complementing the data base on the kinds of lead whites used in Polish painting workshops of the mediaeval times.

    Full Text Available Neste artigo são exploradas as relações, na psicologia vigotskiana, entre o indivíduo em desenvolvimento e as formas mais ricas de individualidade, de conhecimento e de linguagem. A proposição metodológica que Karl Marx apresenta em sua clássica análise do método da economia política, segundo a qual, a anatomia humana é uma chave para a anatomia do macaco, ou seja, a forma mais desenvolvida é uma referência para a compreensão da menos desenvolvida, é vista por Vigotski como força motora do desenvolvimento psíquico humano. Esse psicólogo defende que a relação com o adulto é necessária ao desenvolvimento da criança. Igualmente ele postula que a individualidade se desenvolve do “em si” ao “para si” e que os sistemas de instrumentos psicológicos mais ricos são indispensáveis ao alcance de níveis mais elevados de desenvolvimento psíquico.

  3. Habermas e a Religião: por uma dialética da secularização

    Directory of Open Access Journals (Sweden)

    Juliano Cordeiro da Costa Oliveira

    2017-05-01

    Full Text Available Este artigo tem como objetivo investigar a relação entre razão e religião no âmbito do que Jürgen Habermas chama hoje de sociedade pós-secular. Duas tendências, para ele, caracterizariam nossa época: a proliferação de imagens de mundo naturalistas e a influência política crescente também das ortodoxias religiosas, constituindo este diagnóstico um dos temas mais recentes da reflexão de Habermas. Ele busca, no entanto, um lugar intermediário entre o naturalismo cientificista e a religião, numa perspectiva crítica em relação a um caminho unilateral tanto da ciência como da religião. Para ele, cidadãos seculares e religiosos devem estar dispostos a se ouvirem reciprocamente nos debates públicos e a aprenderem uns com os outros. Segundo Habermas, começa a prevalecer, na sociedade pós-secular e não mais apenas secular, a ideia de que tanto as mentalidades religiosas quanto as seculares precisam se modificar de forma reflexiva, aprendendo as contribuições de uma e de outra para os diversos temas.

  4. Nosso corpo nos pertence: a dialética do biológico e do social

    Directory of Open Access Journals (Sweden)

    Karen Mary Giffin

    1991-06-01

    Full Text Available Este artigo visa situar a discussão do biológico e do social no interior da análise da condição feminina. Com o surgimento das análises feministas, a hegemonia anterior das explicações biológicas é substituída por uma ênfase na construção social da identidade feminina. O determinismo biológico é repudiado, mesmo quando a identificação da mulher com o corpo e com a natureza e seu status secundário são considerados como universais. Neste processo de reelaboração do objeto, o papel ideológico da ciência é apontado, na medida em que a dominação masculina na ciência e na sociedade acompanhou a tendência histórica que relegou a questão da mulher à esfera natural. Embora uma crescente apreciação da construção social da atividade científica em si impulsione o abandono da dicotomia biológico/social ao nível conceitual, as diferenças entre homem e mulher na esfera da reprodução continuam a atuar. É argumentado que análise da reprodução requer caracterização dos sexos como entidades biossociais em relacionamento, situados em contextos históricos específicos, e que, na sociedade moderna, a mulher é sujeita a uma dupla contradição reprodutiva.This article aims at reviewing the discussion of biological and social factors in the analysis of women's social condition. With the appearance of a feminist perspective, the dominance of earlier biologically-based explanations was substituted by an emphasis on the social construction of female identity. Even when women's identification with the body and with nature, and their secondary status, were considered universal, biological determinism was rejected. In this process of re-definition of the object of study, the ideological role of science was pointed out, since male dominance in science and society accompanied the historical tendency which relegated "the woman question" to the sphere of natural fact. Although growing awareness of the socially-constructed nature of scientific activity itself is producing a tendency to abandon the biological/social dichotomy at the conceptual level, differences between men and women in the reproductive sphere continue to exist. It is argued that analysis of reproduction requires characterization of the sexes as biosocial entities in relationship, situated in specific historical contexts, and that in modern society women are subject to a double reproductive contradiction.

    2006-04-15

    Telecommunications will play a major role in the construction of the Mackenzie Gas Project due to the remoteness of its location and the volume of communication data required to support the number of people involved and the amount of construction activity. While suppliers for communications tools have not yet been identified, initial telecommunications plans call for the installation of communication equipment at all camps, major facility sites and construction locations. Equipment will be housed in self-contained, climate-controlled buildings called telecommunication service modules (TSMs), which will be connected to each other as well as to existing public communications networks. The infrastructure will support telephone and fax systems; Internet and electronic mail services; multiple channel very high frequency radios; air-to-ground communication at airstrips and helipads; ship-to-shore at barge landings; closed circuit television; satellite community antenna television; CBC radio broadcast; public address systems; security systems; and supervisory control and data acquisition (SCADA) systems. An Internet Protocol (IP) network with a voice telephone system will be implemented along with a geostationary orbit satellite network. Satellite servers and real-time data services will be used. Car kits that allow call and battery-operated self-contained telemetry devices designed to communicate via a satellite system have been commissioned for the project that are capable of providing cost-efficient and reliable asset tracking and fleet management in remote regions and assisting in deployment requirements. It was concluded that many of today's mega-projects are the driving factors behind new telecommunications solutions in remote areas. 1 fig.

  11. Spectral probes of the holographic Fermi ground state: Dialing between the electron star and AdS Dirac hair

    International Nuclear Information System (INIS)

    Cubrovic, Mihailo; Liu Yan; Schalm, Koenraad; Sun Yawen; Zaanen, Jan

    2011-01-01

    We argue that the electron star and the anti-de Sitter (AdS) Dirac hair solution are two limits of the free charged Fermi gas in AdS. Spectral functions of holographic duals to probe fermions in the background of electron stars have a free parameter that quantifies the number of constituent fermions that make up the charge and energy density characterizing the electron star solution. The strict electron star limit takes this number to be infinite. The Dirac hair solution is the limit where this number is unity. This is evident in the behavior of the distribution of holographically dual Fermi surfaces. As we decrease the number of constituents in a fixed electron star background the number of Fermi surfaces also decreases. An improved holographic Fermi ground state should be a configuration that shares the qualitative properties of both limits.

    Full Text Available This essay intends to offer a first approach to some works that have been rarely taken into account by literary criticism: Cuban crime and contraspying theatre. These texts were mainly produced in the 70s and early 80s due to the success of the novels dealing with the same topics. They clearly show the link between literature and ideology that was the core of the an important part of Cuban cultural production of the period. Some plays are specially dealt with Ha muerto una mujer, Ernesto y Aquí del G-2 soy yo by Gerardo Fernández García and Crimen en Noche de máscaras, by Antonio Veloso y Rodolfo Pérez Valero.

    Esta contribución pretende ofrecer un primer acercamiento a un corpus que ha sido escasamente considerado por la crítica: la producción dramática cubana policiaca o de contraespionaje.

  18. ‘Locality, nation and the “primitive” – notions about the identities of late medieval non-professional wall painters in Finnish historiography from 1880 to 1940’

    Directory of Open Access Journals (Sweden)

    Katja Fält

    2013-12-01

    Full Text Available The article examines a group of medieval wall paintings and how they have been dealt with in the Finnish research history during the period from 1880 to 1940. The paintings have long been referred to ‘primitive paintings’ and thought to have been executed by local men. This interpretation has been in connection to the late nineteenth and early twentieth century history-writing and its attempts to establish and validate a shared national past for Finland. The notion of the ‘primitive paintings’ as something essentially local or ‘native’, was an endeavour of cultural construction that aimed to recreate a continuous, plausible narrative as a part of ‘writing the nation’ in the late-nineteenth and early-twentieth-century Finnish historiography.

    Full Text Available Dans cet article, Eamonn Wall considère les œuvres de divers artistes et penseurs de l’âge classique à l’époque actuelle, et tente de décrire les diverses méthodologies choisies par les écrivains et leurs commentateurs pour écrire des poèmes et les interpréter. Il sera principalement question ici des poètes de l’École de New York qui, apparue dans les années 1950, comprenait parmi ses membres des poètes tels que John Ashbery, Frank O’ Hara, James Schuyler, Kenneth Koch, et bien d’autres encore. Ce mouvement poétique empruntait son nom au groupe de peintres qui occupa la scène new yorkaise après la Deuxième Guerre mondiale. Eamonn Wall s’arrête sur différents points de convergence et de dissonance entre les poètes et les peintres de ces Écoles, avant de considérer les liens entre poésie et arts visuels dans l’Irlande et la Grande-Bretagne tant contemporaines qu’anciennes afin de montrer les échecs et les réussites des poètes qui essayèrent de faire de la poésie à partir des arts visuels. Il conclut que pour un poète, un tableau est toujours un sujet irrésistible et se montre certain que tant qu’il y aura des œuvres aux murs des musées, il y aura des poètes pour les mettre en poésie.

    Full Text Available Citando los ejemplos de los Tamils de Sri Lanka, los Sikhs de la India, los chinos non-Han, las sublevaciones populares en Afganistán contra los rusos, las de Cisjordania contra los judíos israelíes y en Rusia contra la minoría étnica rusa, el nacionalismo y el rechazo de "lo extranjero" se postula como la realidad cultural del siglo XX. Se presume como causa la tecnología, que propicia un acercamiento del mundo hacia una cultura global, existiendo así una lucha por mantener identidades nacionales familiares; de este modo, "lo extranjero" es reprimido violentamente. "Lo extranjero", incluyendo lo positivo y lo negativo que se le atribuye, ha sido una fuerza universal en la historia humana; una ayuda a las sociedades para analizar ambigüedades en épocas de agitación.

  6. Computer Simulation of Global Profiles of Carbon Dioxide Using a Pulsed, 2-Micron, Coherent-Detection, Column-Content DIAL System

    We present preliminary results of computer simulations of the error in measuring carbon dioxide mixing ratio profiles from earth orbit. The simulated sensor is a pulsed, 2-micron, coherent-detection lidar alternately operating on at least two wavelengths. The simulated geometry is a nadir viewing lidar measuring the column content signal. Atmospheric absorption is modeled using FASCODE3P software with the HITRAN 2004 absorption line data base. Lidar shot accumulation is employed up to the horizontal resolution limit. Horizontal resolutions of 50, 100, and 200 km are shown. Assuming a 400 km spacecraft orbit, the horizontal resolutions correspond to measurement times of about 7, 14, and 28 s. We simulate laser pulse-pair repetition frequencies from 1 Hz to 100 kHz. The range of shot accumulation is 7 to 2.8 million pulse-pairs. The resultant error is shown as a function of horizontal resolution, laser pulse-pair repetition frequency, and laser pulse energy. The effect of different on and off pulse energies is explored. The results are compared to simulation results of others and to demonstrated 2-micron operating points at NASA Langley.

São analisadas duas questões fundamentais: o crescente processo de exclusão social, de grande parte da população mundial, e o papel do Estado-Nação. Considera-se esta última questão extremamente relevante, pois diante de uma tendência intrínseca do sistema à concentração da riqueza, de um lado, e a expansão da pobreza, de outro, o Estado se apresenta como a única salvaguarda real dos interesses vitais dos excluídos em cada país. Discutem-se também alguns aspectos da crise atual do sistema capitalista e o impacto do modelo neoliberal no acirramento das contradições sociais e na polarização dos interesses de classe. Propõe-se uma reflexão sobre formas alternativas de organização social.The purpose of this work is to rethink the process of capitalist development, pointing out to some of global society's numerous contradictions. Two central issues are examined: the growing process of social exclusion of a sizable part of the world population and the role of the nation-state. The latter is seen as extremely relevant in the light of the system's intrinsic trend to concentrate wealth while expanding poverty, when the state comes as the only real safeguard for vital interests of those excluded in each country. Some aspects of the current crisis in the capitalist system and the impact of the neoliberal model in deepening social contradictions and polarizing class interests are also discussed. A reflection on alternative forms of social organization is put forward.

    In the absence of climate change policies, the fossil fuel emissions are projected to increase in the next decades. Depending on how the current carbon sinks change in the future, the atmospheric CO2 concentration is predicted to be between 700-1000 ppmv by 2100, and global mean surface temperature between 1.1-6.4°C, with related changes in sea-level, extreme events and ecosystem drifts. Keeping the atmospheric CO2 concentration at a level that prevents dangerous interference with the climate system poses an unprecedent but necessary challenge to humanity. Beyond this point, global climate change would be very difficult and costly to deal with. There are two main approaches that are currently analysed: (1) to reduce emissions; (2) to capture CO2 and store it, i.e. sequestration. For these two ways, some monitoring at different scales ultimately from space would be needed. Lidar remote sensing is a powerful technique that enables measurements at various space and time resolution.

  14. The use of multi-energy-group neutron diffusion theory to numerically evaluate the relative utility of three dial-detector neutron porosity well logging tools

    Zalan, T.A.

    1988-01-01

    Multi-energy-group neutron diffusion theory is used to numerically evaluate the utility of two different dual-detector neutron porosity logging devices, a 14 MeV (accelerator) neutron source - epithermal neutron detector device and a 4 MeV neutron source - capture gamma-ray detector device, relative to the traditional 4 MeV neutron source - thermal neutron detector device. Fast and epithermal neutron diffusion parameters are calculated using Monte Carlo - derived neutron flux distributions. Thermal parameters are calculated from tabulated cross sections. An existing analytical method to describe the transport of gamma-rays through common earth materials is modified in order to accommodate the modeling of the 4 MeV neutron - capture gamma-ray device. The 14 MeV neutron - epithermal neutron device is found to be less sensitive to porosity than the 4 MeV neutron - capture gamma-ray device, which in turn is found to be less sensitive to porosity than the traditional 4 MeV neutron - thermal neutron device. Salinity effects are found to be comparable for the 4 MeV neutron - capture gamma-ray and 4 MeV neutron - thermal neutron devices. The 4 MeV neutron capture gamma-ray measurement is found to be deepest investigating

Las instituciones subregionales de integración viven una crisis que difícilmente podrá ser resuelta por la UNASUR, ya que los Estados se debaten entre un proyecto que propicia una integración abierta al mundo sin exclusiones, basado en la democracia como forma de gobierno, el libre comercio como vía para el desarrollo, el respeto a los derechos humanos como ética política, y la observancia de la soberanía y del principio de no injerencia para la cooperación internacional, y otro, que propugna una integración cerrada centrada en el ámbito regional, e impulsa un proyecto socialista revolucionario transnacional que es democráticamente regresivo y esencialmente anti-norteamericano. La agresividad ideológica, verbal y la intervención en asuntos internos de otros Estados ha llegado a un nivel tal que, por primera vez desde el siglo XIX, se plantean hipotéticas guerras subregionales que afectarían a la estabilidad, la paz y la gobernabilidad en la región, ello en un contexto actual de presiones políticas para que los países y las instituciones de integración tomen partido, quebrándose así su neutralidad.

    Cellphone use while driving is having a noticeable impact on driver safety. Driving is the leading cause of death in the petroleum industry. Traffic collisions have increased by nearly 15 per cent since 2005. Driver error is considered to be a contributing factor in 9 out of 10 traffic collisions. The media has desensitized and conditioned most people to accept road deaths as inevitable. However, a number of people are now expressing deep concerns over the carelessness of drivers who use their cellphones while on the road. This paper described a campaign recently launched by Alberta's safety training company Enform to develop a policy about cellphone use. The awareness program has been developed to inform the public of the dangers of cellphone use. A team of people have also been hired to conduct safety initiatives in local communities in Alberta. The program is part of the The Alberta Traffic Safety Plan (TSP), which was formed in order to consider methods of increasing public education and awareness, sustained enforcement, legislation, best practices, and safety-based engineering. 3 figs.

    1982-12-01

    It is evident from a survey of the current literature that a problem exists in finding the correlation between the exposure of the human body to radiation, with the subsequent development of diseases, particularly for certain types of cancer. A brief history of the early experiences of radium incorporation into humans is given followed by data collected on some important polulation groups exposed to radium body burden, such as miners in rare metal and uranium mines, dial painters and some groups of patients. The medical and technical applications of radium are discussed. A summary is also given of the natural occurence of radium and the amounts in which it is present in the environment. Incorporation, retention and excretion pathways are outlined. In order to study the metabolism and the induction of diseases by radium several animal studies have been performed. The ICRP regards radium-226 as the best known and most studied radionuclide. It can thus serve as a guideline for setting limits for other radionuclides, e.g. plutonium. The valid limiting value for radium-226 of 0.1 μCi for whole body exposure is generally accepted and regarded as sufficiently safe. Finally, transfer factors have been collected as fas as they were available in the literature. (orig./MG) [de

    There is a continuing need to understand dose-response relationships for ionizing radiation in order to protect the health of the public and nuclear workers from undue exposures. However, relatively few human populations have been exposed to doses of radiation high enough to cause observable, long-term health effects from which to derive dose-response relationships. This is particularly true for internally deposited radionuclides, although much effort has been devoted to epidemiological studies of the few types of exposures available, including lung cancers in uranium miners form the inhalation of the radioactive decay products of Ra, liver cancers in patients injected with Thorotrast X-ray contrast medium containing Th, bone cancers in radium dial painters who ingested Ra, and bone cancers in patients who received therapeutic doses of Ra. These four types of exposures to internally deposited radionuclides provide a basis for understanding the health effects of many other radionuclides for which a potential for exposure exists. However, potential exposures to internally deposited radionuclides may differ in many modifying factors, such as route of exposure, population differences, and physical, chemical, and elemental forms of radionuclides. The only means available to study many of these modifying factors has been in laboratory animals, and to then extrapolate the results to humans. Three conclusions can be drawn from this example.

  6. Survey of studies of occupational populations exposed to low-level radiation

    International Nuclear Information System (INIS)

    Marks, S.

    1980-04-01

    Studies of occupational populations exposed to large doses of radiation, principally from the ingestion of radium by dial painters and inhalation of radon and its daughters by miners, have provided important information on the health effects of those radioisotopes. Studies of medical radiologists, military personnel exposed to nuclear tests, and factory workers exposed to thorium are in progress. Employees of DOE-contractor facilities and of naval shipyards are also under study. Personnel dosimetry data are generally available for the latter category of occupational populations. Reasons for conducting the studies include interest in exploring the verification at low exposure levels of results of studies of heavily exposed populations and the responsibility of the employer to maintain adequate surveillance of the health of his workers by conducting appropriate epidemiologic studies. The low level of exposure of workers in facilities where adequate personnel dosimetry records are available make it unlikely that the results of such studies can be used to provide health risk estimates in the near future

  7. The toxicity of the bone seeking radionuclides

    International Nuclear Information System (INIS)

    Spiers, F.W.

    1989-01-01

    This editorial concludes that it is evident from work on radium dial painters at the Argonne National Laboratory and on beagles at the Universities of Utah and California that irradiation by α particles from 226 Ra and 239 Pu incorporated in bone results in tumours of bone but rarely if at all in tumours arising from bone marrow. The same can probably be said of α particle irradiation by other radionuclides deposited in bone or on bone surfaces. If α particles arise in bone or on bone surfaces, the trabecular marrow can be only partially irradiated with considerable fractions of marrow left intact. On the other hand it is evident from beagle data that when bone marrow is totally irradiated by the long range β particles from 90 Sr, whether fed orally or administered by single injection, both marrow neoplasms and bone tumours occur. Total irradiation of bone marrow by γ radiation, and some neutron radiation at Hiroshima and Nagasaki also resulted in leukaemia induction. (author)

    Data on 63 subjects from several occupational cohorts, plus iatrogenic subjects, were analyzed to determine effects of sex, age at exposure, exposure duration, and age at measurement upon the coefficient of elimination (λ, % y -1 ). While 12 women exposed at age 17-18 had λ's significantly lower than those exposed at ages 15-16 or 21-26, λ showed no overall trend with age at exposure among females. Higher radium burdens associated with bone damage are associated with decreased λ's, but neither exposure duration nor age at measurement correlated significantly with λ. The 12 males had λ's about 60% of those for females after adjustment for retention time. The males λ's were lower the earlier the age at exposure. Effects of personal habits were studied in a homogeneous cohort of female Illinois dial painters with relatively uniform ages at first employment. The most powerful predictor of radium loss was the number of cups of coffee and tea consumed per day. Coffee/tea consumption explained ∼ 35% of the variance in λ, the effect persisting after deletion of smokers and subjects with x-ray evidence of bone damage. Higher weight/height ratios were associated with higher λ's. Individuals smoking throughout the measurement period had significantly low λ's. A complex interaction of weight/height ratios to both smoking and radium-induced bone damage was observed

    1986-01-01

    The toxicity ratio concept assumes the validity of certain relationships. In some examples for bone sarcoma induction, the approximate toxicity of 239 Pu in man can be calculated algebraically from the observed toxicity in the radium-dial painters and the ratio of 239 Pu/ 226 Ra toxicities in suitable laboratory mammals. In a species highly susceptible to bone sarcoma induction, the risk coefficients for both 239 Pu and 226 Ra are elevated, but the toxicity ratio of 239 Pu to 226 Ra tends to be similar to the ratio in resistant species. Among the tested species the toxicity ratio of 239 Pu to 226 Ra ranged from 6 to 22 (a fourfold range), whereas their relative sensitivities to 239 Pu varied by a factor of 150. The toxicity ratio approach can also be used to estimate the actinide risk to man from liver cancer, by comparing to the Thorotrast patients; from lung cancer, by comparing to the uranium miners and the atomic-bomb survivors; and from neutron-induced cancers, by comparing to cancers induced by gamma rays. The toxicity ratio can be used to predict the risk to man from a specific type of cancer that has been reliably induced by a reference radiation in humans and that can be induced by both the reference and the investigated radiation in suitable laboratory animals. 26 refs., 3 figs., 1 tab

  10. CEDR: Comprehensive Epidemiologic Data Resource

    Energy Technology Data Exchange (ETDEWEB)

    1993-08-01

    The Department of Energy (DOE) and its predecessor agencies have a long history of epidemiologic research programs. The main focus of these programs has been the Health and Mortality Study of the DOE work force. This epidemiologic study began in 1964 with a feasibility study of workers at the Hanford facility. Studies of other populations exposed to radiation have also been supported, including the classic epidemiologic study of radium dial painters and studies of atomic bomb survivors. From a scientific perspective, these epidemiologic research program have been productive, highly credible, and formed the bases for many radiological protection standards. Recently, there has been concern that, although research results were available, the data on which these results were based were not easily obtained by interested investigators outside DOE. Therefore, as part of an effort to integrate and broaden access to its epidemiologic information, the DOE has developed the Comprehensive Epidemiologic Data Resource (CEDR) Program. Included in this effort is the development of a computer information system for accessing the collection of CEDR data and its related descriptive information. The epidemiologic data currently available through the CEDAR Program consist of analytic data sets, working data sets, and their associated documentation files. In general, data sets are the result of epidemiologic studies that have been conducted on various groups of workers at different DOE facilities during the past 30 years.

    There is a long history recording the association of x radiation and the subsequent development of malignant tumors. For systemically administered isotopes this came into prominence when Martland discovered the association between cancer, particularly of the bone, and ingestion of radioactive isotopes by radium dial painters. This association was amplified by the development of cancer in patients given thorotrast as a contrast medium for diagnostic radiologic examination. Acute leukemia was reported 30 years ago in patients with polycythemia vera treated with 32 P. Acute leukemia also occurs in patients with polycythemia vera treated only with phlebotomy or drugs. A controlled study is now underway to provide a more definite answer to question what is the incidence of acute leukemia in patients with polycythemia vera treated by phlebotomy alone, chlorambucil, or 32 P. 131 I for the treatment of hyperthyroidism probably does not induce cancer, but in the doses used for thyroid cancer there was an increased incidence of neoplasms (12/200 in one study). This was higher than the expected incidence of neoplasms. The doses of radioactive isotopes used currently for diagnostic purposes have not induced cancer, but it is difficult and probably impossible to verify this with absolute certainty

  12. Internal dosimetry, past and future

    Johnson, J.R.

    1989-03-01

    This paper is a review of the progress in the dosimetry of internally deposited radionuclides (internal dosimetry) since World War II. Previous to that, only naturally occurring radionuclides were available and only a limited number of studies of biokinetics and dosimetry were done. The main radionuclides studied were 226 Ra, 228 Ra, and 224 Ra but natural uranium was also studied mainly because of its toxic effect as a heavy metal, and not because it was radioactive. The effects of 226 Ra in bone, mainly from the radium dial painters, also formed the only bases for the radiotoxicity of radionuclides in bone for many years, and it is still, along with 224 Ra, the main source of information on the effects of alpha emitters in bone. The publications of the International Commission on Radiological Protection that have an impact on internal dosimetry are used as mileposts for this review. These series of publications, more than any other, represent a broad consensus of opinion within the radiation protection community at the time of their publication, and have formed the bases for radiation protection practice throughout the world. This review is not meant to be exhaustive; it is meant to be a personnel view of the evolution of internal dosimetry, and to present the author's opinion of what the future directions in internal dosimetry will be. 39 refs., 2 tabs

At the end of the 19th century scientists researching the newly found radiation called ''radioactivity'' became exposed frequently to uranium, thorium and their decay chains, still hardly aware of the potential risks associated with their work. In the first half of the 20th century some employees in the radium industry received high doses in the course of their professional duties as chemists, maintenance workers, or radium dial painters; many of them lacked adequate information on radiation protection. After World War II the increased international demand for uranium in the military and civilian sector caused overexposures of several thousands of miners (volunteers, prisoners), mostly due to the inhalation of elevated levels of radon and its decay products. By comparison on an international scale a relatively small number of workers was exposed to increased levels of thorium and its decay products in the thorium and rare-earth extraction industry. Health effects due to these past exposures range from relatively weak associations to statistically significant excesses for a variety of symptoms, such as respiratory diseases or cancer of the bone, lung or pancreas. An assessment of today industrial exposure situations indicates a wide range of occupations exposed to partly significant levels of natural radionuclides. 36 refs., 7 tabs., 3 figs

    There is a continuing need to understand dose-response relationships for ionizing radiation in order to protect the health of the public and nuclear workers from undue exposures. However, relatively few human populations have been exposed to doses of radiation high enough to cause observable, long-term health effects from which to derive dose-response relationships. This is particularly true for internally deposited radionuclides, although much effort has been devoted to epidemiological studies of the few types of exposures available, including lung cancers in uranium miners form the inhalation of the radioactive decay products of Ra, liver cancers in patients injected with Thorotrast X-ray contrast medium containing Th, bone cancers in radium dial painters who ingested Ra, and bone cancers in patients who received therapeutic doses of Ra. These four types of exposures to internally deposited radionuclides provide a basis for understanding the health effects of many other radionuclides for which a potential for exposure exists. However, potential exposures to internally deposited radionuclides may differ in many modifying factors, such as route of exposure, population differences, and physical, chemical, and elemental forms of radionuclides. The only means available to study many of these modifying factors has been in laboratory animals, and to then extrapolate the results to humans. Three conclusions can be drawn from this example

    Lymphocyte stimulation by different concentrations of phytohemmagglutinin (PHA) provided a profile of lymphocyte responsiveness in 5 normal subjects and 40 radium dial painters. This profile will, hopefully, improve detection of lymphocyte defects in patients with impairment of cellular immunity. When a suboptimal dose (0.15 μg PHA-protein) was used, decreased lymphocyte responsiveness was observed in patients with high body burdens of 226 Ra (> 0.1 μCi) compared with patients with low body burdens (< 0.1 μCi) and normal subjects. At all other PHA concentrations, the lymphocyte responsiveness was not significantly different in these three groups. A decrease in lymphocyte response was found with age in both normal controls and in the radium patients, but the decrease appeared to be somewhat greater in the radium patients above 50 years of age. To test the significance of these findings, larger numbers of control subjects in the higher age groups and low body burden radium patients known not to be on any type of medication will have to be examined

Research in fact raised a set of theoretical and methodological questions, one of which is to understand the processes through which people from traditional oral cultures build up references on literacy so that they may still perceive themselves as subjects of their own history. The confrontation of the theoretical and methodological principles available in the field of psychology and anthropology has been essential to current search. In fact, it aims at overcoming classical antinomies in the field of psychology: individual and culture; concrete and abstract.

    Multiple myeloma (MM) is an incurable plasma cell malignancy with a poorly understood etiology. The purpose of our research was to examine the relationships between lifetime occupations and MM in a relatively large case-control study. MM cases (n = 180) were identified through cancer registries in the Seattle-Puget Sound area and Detroit. Population-based controls (n = 481) were identified using random digit dialing and Medicare and Medicaid Services files. In-person interviews were conducted to ascertain occupational histories. Standard occupational classification (SOC) and standard industrial classification (SIC) codes were assigned to each job held by each participant. Unconditional logistic regression was used to generate odds ratios (ORs) and 95% confidence intervals (CIs) for associations between MM and having ever worked in each occupation/industry and according to duration of employment in an occupation/industry. The risk of MM was associated with several manufacturing occupations and industries, including machine operators and tenders, not elsewhere classified (SOC 76) (OR = 1.8, CI = 1.0-3.3); textile, apparel, and furnishing machine operators and tenders (SOC 765) (OR = 6.0, CI = 1.7-21); and machinery manufacturing, except electrical (SIC 35) (OR = 3.3, CI = 1.7-6.7). Several service occupations and industries, such as food and beverage preparation (SOC 521) (OR = 2.0, CI = 1.1-3.8), were also associated with MM. One occupation that has been associated with MM in several previous studies, painters, paperhangers, and plasterers (SOC 644) was associated with a non-significantly elevated risk (OR = 3.6, CI = 0.7-19). We found associations between the risk of MM and employment in several manufacturing and service-related occupations and industries. Copyright 2010 Wiley-Liss, Inc.

Responsibility for tissue radioanalysis was transferred from Los Alamos National Laboratory to Washington State University in February 1994. The University of Washington was selected as the Quality Assurance/Quality Control laboratory and a three way intercomparison with them and LANL has been initiated. The results of the initial alpha spectrometry intercomparison showed excellent agreement among the laboratories and are documented in full in the Appendices to the report. The NHRTR serves as the initial point of receipt for samples received from participants in the USTUR program. Samples are weighed, divided, and reweighed, and a portion retained by the NHRTR as backup or for use in other studies. Tissue specimens retained in the NHRTR are maintained frozen at -70 C and include not only those from USTUR registrants but also those from the radium dial painter and thorium worker studies formerly conducted by Argonne National Laboratory. In addition, there are fixed tissues and a large collection of histopathology slides from all the studies, plus about 20,000 individual solutions derived from donated tissues. These tissues and tissue related materials are made available to other investigators for legitimate research purposes. Ratios of the concentration of actinides in various tissues have been used to evaluate the biokinetics, and retention half times of plutonium and americium. Retention half times for plutonium in various soft tissues range from 10-20 y except for the testes for which a retention half time of 58 y was observed. For americium, the retention half time in various soft tissues studied was 2.2-3.5 y.

    Data available on the biological effects of radiation on man are reviewed, with emphasis on dose response to low LET and high LET radiation sources, and the effects of dose rate. Existing guides for radiation protection were formulated largely on the basis of tumor induction in the bone of radium dial painters, but the ICRP/NCRP annual dose guides of 5 rem/yr are of the same general magnitude as the doses received in several parts of the world from the natural radiation environment. Because of the greater sensitivity of rapidly dividing cells and the assumption that radiation occupations would not begin before the age of eighteen, maximum exposure levels were set as 5 (N-18) rem/yr, where N is the exposed worker's age in years. However, in the case of the natural radiation environment, exposure commences, in a sense, with the exposure of the ovum of the individual's mother; and the ovum is formed during the fetal development of the mother. In occupational exposures, the professional health physicist has always practiced the as low as practical philosophy, and exposures have generally averaged far below the guidelines. The average annual exposure of the radiation worker in modern plants and laboratories is approximately equal to the average natural radiation environment exposure rate and far lower than the natural radiation environment in many parts of the world. There are numerous complications and uncertainties in quantifying radiation effects on humans, however, the greatest is that due to having to extrapolate from high dose levels at which effects have been measured and quantified, to low levels at which most exposures occur but at which no effects have been observed

  2. Stem cell targets and dosimetry for radiation-induced leukaemia and bone cancer

    The ICRP are proposing changes to the assumed targets for the induction of bone cancer and leukaemias as described by Harrison et al in an accompanying article. This study of radiation targets in the skeleton finds that the endosteum of the long bone medullary cavities is not an important target, especially in the adult, as it supports a very low stem cell population associated with high adiposity, whereas the periosteum has a strong mesenchymal stem cell population throughout lifetime. Quiescent stem cells are found to be preferentially located close to the trabecular bone surface in the osteoblastic niche, whereas progenitors of stem cells prefer to reside in perivascular niches. Evidence is given in support of the suggestion that the absence of excess bone-cancer in atomic bomb survivors may be related to the extremely low prevalence of Paget's disease in Japan. The hypoxic conditions of the endosteum adjacent to quiescent bone surfaces provide a radioprotective stem cell microenvironment by a factor of 2-3 fold, whereas greater radiosensitivity is prevalent in the young and individuals with benign diseases of bone. Increasing the volume of the bone cancer target from a 10 μm thick endosteum to a 50 μm peripheral marrow layer will result in an approximately three-fold decline in the mean dose from alpha-emitters in bone. These new observations are shown to go some way in explaining the low incidences for leukaemia and especially bone cancer in radium dial painters, Thorotrast patients and Mayak nuclear workers.

    Peripheral lymphocytes from 10 controls and 40 patients with body burdens of 226 Ra ranging from below the limit of detection to 8.6 μCi were scored for unstable chromosome aberrations. The patient population was divided into four groups: a group with body burdens below the limit of detection (less than 0.003 μCi, 12 patients); a low-burden group (0.003 to 0.099 μCi, 13 patients); a moderate-burden group (0.1 to 0.99 μCi, 11 patients); and a high-burden group (greater than 1.0 μCi, 4 patients). In none of these groups was the frequency of cells with unstable aberrations significantly elevated above that in the controls. The rate of occurrence of dicentric and ring chromosomes was above the control frequency in only the two patients with the highest burdens (3.55 and 8.6 μCi). Our results are consistent with the expectation derived from a recent calculation of alpha dose delivered to blood by bone-deposited radium and its decay products. Marshall and Hoegerman have estimated that the blood dose for an individual with a radium burden of 1.0 μCi is 0.09 +- 0.03 rad/year. The value is compared with the dose estimate used by Boyd et al. in their study of British radium-dial painters, and the relevance of the blood dose to the lymphocyte dose is discussed

    This paper traces the evolution of the linear nonthreshold dose-response model and its acceptance as a paradigm in radiation protection practice and risk analysis. Deterministic effects such as skin burns and even deep tissue trauma were associated with excessive exposure to x rays shortly after their discovery, and carcinogenicity was observed as early as 1902. Still, it was not until 1925 that the first protective limits were suggested. For three decades these limits were based on the concept of a tolerance dose which, if not exceeded, would result in no demonstrable harm to the individual and implicitly assumed a threshold dose below which radiation effects would be absent. After World War II, largely because of genetic concerns related to atmospheric weapons testing, radiation protection dose limits were expressed in terms of a risk based maximum permissible dose which clearly implied no threshold. The 1927 discovery by Muller of x-ray induced genetic mutations in fruit flies, linear with dose and with no apparent threshold, was an important underpinning of the standards. The linear nonthreshold dose-response model was originally used to provide an upper limit estimate of the risk, with zero being the lower limit, of low level irradiation since the dose-response curve could not be determined at low dose levels. Evidence to the contrary such as hormesis and the classic studies of the radium dial painters notwithstanding, the linear nonthreshold model gained greater acceptance and in the centennial year of the discovery of x rays stands as a paradigm although serious questions are beginning to be raised regarding its general applicability. The work includes a brief digression describing the work of x-ray protection pioneer William Rollins and concludes with a recommendation for application of a de minimis dose level in radiation protection.

Through the analysis of four dialogues extracted from two literary Portuguese language works of two different centuries, we demonstrate how the conversational structures of verbal exchanges have not changed over the time, despite the different schools and literary currents that have occurred since the medieval times until the contemporary era. The text chosen are taken from the novels A queda d'um anjo and Amor de perdição: memorias duma família of Camilo Castelo Branco (1825-1890 and from the contemporary work Não há coincidências of Margarida Rebelo Pinto: the choice of these extracts was not random, but taking into account the use of dialogue as a conversational technique, between characters, by these authors who use it in their fiction works in order to involve more actively the reader on the reported events.

    Full Text Available Dos han sido los prismas bajo los que se ha concebido tradicionalmente a la audiencia: como ciudadanos, que ante los mensajes de los medios ejercen sus derechos comunicativos y participan en la construcción de una opinión pública libre; o como consumidores o usuarios, que actúan dentro de un mercado de productos audiovisuales. Mientras que la primera perspectiva atiende a la comunicación audiovisual valorando su interés público y su influencia en la construcción de un espacio público de debate y discusión, la segunda atiende a la dimensión más privada e individual de la comunicación audiovisual. En el presente trabajo se abordan las principales posiciones doctrinales sobre dicha dicotomía consumidor-ciudadano, analizando para ello la obra de los autores que más atención han dedicado a estas cuestiones en el ámbito europeo, y en especial los trabajos de Peter Dahlgren sobre las relaciones entre medios y democracia, los de Richard Collins sobre política audiovisual, y los vinculados a Sonia Livingstone sobre esfera pública, participación de las audiencias y gobernanza de los medios. Realizada esta aproximación teórica, se analiza la presencia de dichas concepciones de la audiencia en dos ordenamientos jurídicos audiovisuales que están experimentando modificaciones sustanciales: el español y el mexicano. Como conclusión, se constata que las distintas concepciones de la audiencia están en profunda relación con la forma de concebir el control de los medios y la rendición de cuentas de sus operadores frente al público.

Arendt’s The burden of our times (1951, which takes into account this work as an analysis of the causes that led to the crisis and fall of the modern Nation-state, displaying the elements which brought forth the most destructive experiment which the political condition of man was subjected to, i.e. the totalitarian phenomenon. I shall begin by outlining the reasons of Arendt’s disdain for the rules of sociological method, since she considers that human actions can only retrospectively illuminate which are the elements that actually led to the historical events. Secondly, I tackle the incompatibility that Arendt highlights between political and boundless economic enrichment with the help of the criticism she addressed to Hobbes’s Leviathan, that would be guilty of granting theoretical legitimacy to the specific needs of a rising class, the bourgeoisie. Imperialism would thus be the logical consequence of forgetting the principle that commands men transforming the earth as a habitable place, inserting in it a system of legal mediations. Finally, I will deal with the criticism of Arendt on human rights —near to the criticism that she leveled at the nationalism concealed by every national state, whose content she drastically reduces to the requirement of belonging effectively to a political community. Concerning this topic I aim at exploring the possibilities for setting up a dialogue with Kant’s Doctrine of Right, which also assesses the foundation of a civil union as an essential condition for upholding human rights.El artículo propone una lectura de Los orígenes del totalitarismo (1951 de H. Arendt que entiende esta obra como análisis de las causas que condujeron a la crisis y decadencia del Estado-nación moderno y propiciaron el experimento más destructivo de la condición política del hombre, el fenómeno totalitario. Comenzaremos señalando las razones de la displicencia de Arendt hacia las reglas del método sociológico, al considerar que sólo las acciones humanas pueden iluminar retrospectivamente cuáles son los elementos que han cristalizado en los acontecimientos históricos. En segundo lugar, nos detendremos en la incompatibilidad que Arendt encuentra entre poder político y enriquecimiento económico, de la mano de la crítica que realiza del Leviatán de Hobbes, por haber proporcionado una legitimación teórica a las necesidades de una clase en ascenso, la burguesía. El imperialismo sería, así, la consecuencia lógica del olvido del principio que ordena a los hombres volver la tierra un lugar habitable, introduciendo en ella un sistema de mediaciones legales. Finalmente, nos ocuparemos de la crítica que Arendt dirige a los derechos humanos, estrechamente ligada a la destinada al nacionalismo latente en toda forma estatal, que reduce drásticamente su contenido a la exigencia de pertenecer a una efectiva comunidad política, explorando a este respecto las posibilidades de un diálogo con la Doctrina del derecho de Kant, que también hace de la formación de una unión civil una condición fundamental para la defensa efectiva de los derechos del hombre.

    Full Text Available http://dx.doi.org/10.5007/1518-2924.2015v21n45p115 A utilização dos dispositivos de comunicação da web social pelas bibliotecas universitárias públicas brasileiras, como um recurso que pode potencializar a mediação da informação por meio da interação entre usuários e bibliotecários é o tema deste trabalho, que teve por objetivo identificar e analisar como as bibliotecas das universidades federais e estaduais têm explorado os recursos de comunicação nos websites para ampliar suas ações voltadas à mediação para o acesso e uso da informação. A técnica da observação direta e intensiva dos websites foi adotada para análise do uso dos dispositivos de comunicação da web social e se o mesmo tem ampliado a mediação realizada pelas bibliotecas centrais e/ou sistemas de bibliotecas das IES Estaduais e IFES para o acesso e uso da informação. Constatou-se neste trabalho que, ainda são poucos os casos de bibliotecas que, além de disponibilizarem conteúdos relevantes para auxiliar os usuários no acesso e uso da informação, bem como conteúdos sobre a biblioteca, também vêm explorando os dispositivos para favorecer a participação ativa dos usuários na troca de informações, debates, comentários e manifestação de sugestões. Assim, concluiu-se que, embora em menor quantidade e ainda necessitando de maior planejamento nas ações, há uma parcela das bibliotecas centrais e/ou sistemas de bibliotecas das IES Estaduais e das IFES analisadas que têm procurado avançar no modo de aproximação e de relacionamento com os usuários, como também vêm apresentando uma nova conduta de comunicação por parte dos bibliotecários que se mostraram mais acolhedores e amigáveis na interlocução com os usuários por meio dos dispositivos de comunicação da web social.

    Full Text Available Resumo: Distanásia ou qualquer um dos seus sinónimos é uma consequência do excesso terapêutico em relação ao prognóstico esperado. A obstinação terapêutica é um dos dilemas éticos mais angustiantes no quotidiano de medicina intensiva, apesar de a sua apreciação encontrar um suporte normativo em várias instituições e organizações. A manutenção ou não suspensão da ventilação mecânica numa determinada circunstância de fim de vida pode ser considerado como um exemplo paradigmático de obstinação terapêutica.A compreensão desta postura passa pela análise e reflexão do acto médico à luz de alguns conceitos ético-filosóficos. Abstract: Dysthanasia or any of its synonyms is a consequence of excessive technical science, without any reasonable chance of achieving a therapeutic benefit for the patient.Medical futility is a distressing ethical dilemma of intensive care medicine. Its recognition has led to a precept support in various institutions and organizations.Not withdrawing or withholding mechanical ventilation in certain circumstances can be considered as a paradigmatic model of medical futility.The understanding of this posture implies a philosophical approach and reflexion of medical practice.

    Full Text Available Os objetivos deste trabalho foram determinar as capacidades geral e específica de combinação entre variedades locais e sintéticas de milho e identificar cruzamentos que reúnam características de interesse agronômico, com vistas à síntese de variedades. O dialelo parcial foi realizado com 11 variedades sintéticas cruzadas com cinco variedades locais do Paraná. As combinações híbridas resultantes foram avaliadas juntamente com as cinco variedades locais genitoras e com cinco híbridos comerciais, em blocos completos ao acaso com quatro repetições, em São João do Triunfo e Londrina, PR. Houve interação genótipo x local para a maioria dos caracteres avaliados, com predominância da interação da capacidade geral de combinação x local. As melhores estimativas de capacidade geral de combinação do grupo dos sintéticos foram observadas para ST09 e ST04 e, no grupo das variedades, para MC45 e IAPAR 50, considerando-se o conjunto das características e de locais. As melhores combinações híbridas (MC34 x ST04, IAPAR 50 x ST07, MC47 x ST09, MC45 x ST02, MC51 x ST04 e MC45 x ST01 apresentaram estimativas positivas de capacidade específica de combinação quanto à produtividade, em ambos os locais. Existem combinações híbridas com potencial para síntese de novas variedades com padrões de produtividade, altura de planta, posição relativa da espiga e percentagem de espigas danificadas e de plantas acamadas e quebradas melhores que os observados em variedades locais per se e mais semelhantes aos dos híbridos comerciais.The objectives of this work were to determine the general and specific combining ability between landraces and synthetic varieties of maize and to identify the crosses that combine important agronomic traits, to develop new maize varieties. A partial diallel was done with 11 synthetic varieties crossed with five landraces. The crosses were evaluated along with the five parental landraces and five commercial hybrids, in randomized complete block design, with four replicates, in São João do Triunfo and Londrina, PR, Brazil. There was genotype x location interaction for most characters, predominantly from the general combining ability x location interaction. The best estimates of general combining ability of the synthetic group were observed for ST09 and ST04 and, in the variety group, for MC45 and IAPAR 50, taking into consideration the set of traits and locals. The bests crosses (MC34 x ST04, IAPAR 50 x ST07, MC47 x ST09, MC45 x ST02, MC51 x ST04, and MC45 x ST01 had positive estimates of specific combining ability for grain yield in both locals. There are crosses with potential to develop new maize varieties with better grain yield, plant height, ear position, percentage of damaged ears and of lodging and broken stalks than individual maize landraces, and more similar to the performance of commercial corn hybrids.

    Full Text Available To date, normative studies on the generation of public patents have focused on universities. This paper extends the analysis to public research organisations (PRO. From both a historic and economic standpoint, and via the interpretation of three institutional factors (the change in the political and legal background, the dominance of certain areas of science over others, and the increase in technological cooperation, the reasons moving the Consejo Superior de Investigaciones Científicas (CSIC; the Spanish Research Council to file patents were examined. The impact of these quantified factors on patenting was examined from 1987 to the present. The institutional framework of bodies such as the CSIC was found to favour a patenting culture. The historical approach adopted defined homogeneous analytical periods and guided the interpretation of the results and their effects over time, while the economic approach allowed some of the relationships seen to be quantified and questioned the validity of merely descriptive classifications (e.g., scientific areas according to number of patents.

    Hasta la fecha los estudios normativos sobre el origen de patentes públicas han estado centrados en las patentes universitarias. Con este artículo extendemos el análisis a las patentes generadas en los organismos públicos de investigación (OPI. Desde una doble perspectiva, la histórica y la económica, y a través de la interpretación de tres factores institucionales (evolución de los cambios políticos y legales, primacía de unas áreas científicas sobre otras y aumento de la cooperación tecnológica se analiza qué lleva al Consejo Superior de Investigaciones Científicas (CSIC a patentar. Para el último período, desde 1987, hemos cuantificado el impacto de estos factores en las patentes. Hemos concluido que el marco institucional resulta eficaz en un organismo como el CSIC para crear una cultura favorable a la patente. La aproximación histórica define períodos homogéneos de análisis y guía la interpretación de los resultados y sus efectos a lo largo del tiempo, mientras que la aproximación económica cuantifica algunas de las relaciones y pone en cuestión la validez de las clasificaciones meramente descriptivas, por ejemplo, de las áreas científicas según el número de patentes.

    Full Text Available This theoretical reflection intends to show the inter-subjective relationship that takes place in health and nursing practices under the following theoretical perspectives: Institutional Analysis, Psychodynamics of Labor and the Theory of Communicative Action, with an emphasis on the latter. Linking these concepts to the Marxist approach to work in the field of health emerges from recognizing the need for its continuous reconstruction-in this case, with a view to understand the interaction and communication intrinsic to work in action. The theory of Communicative Action seeks to consider these two inextricable dimensions: work as productive action and as interaction. The first corresponds to instrumental action based on technical rules with a production-guided rationale. The second refers to the interaction that takes place as communicative action and seeks understanding among subjects. We assume that adopting this theoretical perspective in the analysis of health and nursing practices opens new possibilities for clarifying its social and historical process and inter-subjective connections.Esta reflexión teórica objetiva poner en evidencia la relación intersubjetiva procesada en el trabajo en salud y enfermería bajo la perspectiva de los siguientes marcos teóricos: Análisis Institucional; Psicodinámica del Trabajo y Teoría de la Acción Comunicativa, con la profundización de este último. La articulación de estas referencias con el enfoque marxista del trabajo en salud parte del reconocimiento de la necesidad de su reconstrucción continua - en el sentido de aprehensión de la interacción y la comunicación, intrínsecos al acto de trabajar. La Acción Comunicativa pretende tener en cuenta estas dos dimensiones inextricables: acción productiva e interacción. La primera corresponde a la acción instrumental basada en reglas técnicas, dirigida a la producción. La segunda realizada como una acción comunicativa destinada al entendimiento entre sujetos. Se supone que la adopción de esta perspectiva en el análisis de las prácticas en salud y enfermería abre nuevas posibilidades para dilucidar sus conexiones sociales, históricas, procesales e intersubjetivas.Esta reflexão teórica objetiva evidenciar a relação intersubjetiva presente no trabalho em saúde e enfermagem sob o olhar das seguintes vertentes teóricas: Análise Institucional; Psicodinâmica do Trabalho e Teoria do Agir Comunicativo, com aprofundamento da última. A articulação desses referenciais à abordagem marxiana do trabalho em saúde parte do reconhecimento da necessidade de sua contínua reconstrução neste caso, no sentido da apreensão da interação e comunicação intrínsecas ao trabalho em ato. A Teoria do Agir Comunicativo busca considerar essas duas inextricáveis dimensões: trabalho como ação produtiva e como interação. A primeira corresponde à ação instrumental baseada em regras técnicas e com uma racionalidade dirigida à produção. A segunda refere-se à interação realizada como ação comunicativa visando o entendimento entre sujeitos.

    Full Text Available Il presente contributo intende riportare l’attenzione sull’attività grafica di Francesco Solimena in una prospettiva rivolta a individuare motivazioni affini alla sodalitas letteraria arcadica, al fine di recuperare nuovi elementi di valutazione, funzionali al raggiungimento di esiti sostanziali sia in senso ripropositivo sia, e soprattutto, in funzione innovativa rispetto ai risultati finora raggiunti. Partendo da un riesame delle relazioni sviluppate nell’ambito delle cerchie arcadiche attive a Napoli e a Roma sono state condotte indagini mirate, rivolte ad apportare chiarimenti alla qualità della ricezione dell’opera solimeniana. Fondamentale è risultato il riferimento alle fonti e ai contributi documentari, in quanto attraverso tale ausilio informativo si è potuto fare il punto su alcuni episodi di committenza, che rimandano a una consuetudine di rapporti mediati dalla comune sensibilità culturale. L’emergere di linee di tendenza non ancora adeguatamente valutate ha indotto a riconsiderare le motivazioni della svolta del Solimena a favore di un purismo formale, affrontando con maggiore chiarezza la ricostruzione di una prassi operativa rivolta a un più severo ripristino dei valori disegnativi e delle sue implicazioni didattiche.   The hereby essay intends to bring back the attention on Francesco Solimena's graphic art in a perspective aimed to identify motivations akin to pastoral literature sodalitas, in order to recover new evaluation elements to reach significant results both in repropositive and, above all, in innovative way compared to the achieved outcomes collected until now. Focused researches were lead in order to clarify the quality of reception of Solimena's work, starting with a re-examination of developed connections in the active pastoral circles in Neaples and Rome. In this essays turns out to be essential the reference to sources and documentary evidences in which it's possible to evaluate some episodes concerning patronage and referring to a custom based relationships mediated by common cultural sensitivity. New trends not yet adequantly judged have induced to reconsider the motivations linked to the Solimena's change in favor a formal purism, dealing with more clarity the reconstruction of an operative practice pointed to a more severe restoration of graphic values and its didactic implications.

    Estimation of radiation doses to the soft tissues from internally-deposited 226 Ra and 228 Ra is relevant to an investigation of soft-tissue malignancies in radium-exposed persons being conducted at the Center for Human Radiobiology. Alpha-particle doses in a 50-year period following a single injection of 226 Ra or 228 Ra are presented for 31 soft tissues and organs of the adult human. The dose estimates were derived from the ICRP alkaline earth model fitted to data on retention of 226 Ra in soft tissues and bone, combined with reported ratios of 226 Ra to Ca in soft tissue and bone at natural levels and the distribution of Ca in the tissues of Reference Man (ICRP23). The median of the 31 organ and tissue doses from the α-particles of 226 Ra itself is 0.08 rad per injected μCi. An additional average dose of 0.01 rad per μCi 226 Ra daughter products produced in soft tissue or transferred from bone to soft tissue. Soft-tissue doses from α-particles of the 228 Ra decay series are about six times those from 226 Ra α-particles for equal injected activities of 228 Ra and 226 Ra, with the assumption that 228 Ra daughter products do not transfer from the organ in which they are produced. The 50-year dose to the red marrow of bone from α-particles originating in bone is 0.55 rad per μCi 226 Ra injected and 1.0 rad per μCi 228 Ra injected. For ingestion by dial painters of luminous compound containg 226 Ra or 228 Ra with a daughter-to-parent activity ratio of 0.5, the dose to the mucosal alyer of the lower large intestine from α-particles originating in the gut contents is about 0.1 rad per μCi systemic intake of 226 Ra or 228 Ra

    Daniell, W.E.

    1993-11-12

    The possibility that previous occupational exposure to solvents might be associated with clinically significant neurological dysfunction in older adults was investigated in a cross-sectional study. Subjects included 67 painters, 22 aerospace painters and fuel cell sealers, and a comparison group of 126 carpenters. All subjects had retired from regular employment at least 1 year prior to the study. As measured by semiquantitative exposure index, the cumulative histories of lifetime occupational solvent exposure were on the average comparable in the two exposed study groups, painters and aerospace workers. The carpenters differed from the other groups in solvent exposure by several orders of magnitude. The painters had a significantly higher history of consuming alcoholic beverages than did the other two study groups. The painters had a significantly higher score on the Beck Depression Inventory, a measure of current depressive symptoms. The painters reported significantly more general neurologic symptoms than did the other two groups. The aerospace workers showed much greater evidence of possible adverse effects from former solvent exposure on current neuropsychological function than did the painters when determined by reasoning and memory tests, memory visual motor speed and motor tests. No evidence of persistent effects on liver or renal excretory function was seen in solvent exposed subjects.

The creation of this painter highlights two phases: the first one lasted until 1965 and the second one lasted from 1968 to the end of the painter's life. Calafateanu mostly painted landscapes (fall and winter, flowers, still life, and nudes.

    To evaluate whether exposure to mobile phone radiation (MPR) can induce DNA damage in male germ cells. A mouse spermatocyte-derived GC-2 cell line was exposed to a commercial mobile phone handset once every 20 min in standby, listen, dialed or dialing modes for 24 h. DNA damage was determined using an alkaline comet assay. The levels of DNA damage were significantly increased following exposure to MPR in the listen, dialed and dialing modes. Moreover, there were significantly higher increases in the dialed and dialing modes than in the listen mode. Interestingly, these results were consistent with the radiation intensities of these modes. However, the DNA damage effects of MPR in the dialing mode were efficiently attenuated by melatonin pretreatment. These results regarding mode-dependent DNA damage have important implications for the safety of inappropriate mobile phone use by males of reproductive age and also suggest a simple preventive measure: Keeping mobile phones as far away from our body as possible, not only during conversations but during 'dialed' and 'dialing' operation modes. Since the 'dialed' mode is actually part of the standby mode, mobile phones should be kept at a safe distance from our body even during standby operation. Furthermore, the protective role of melatonin suggests that it may be a promising pharmacological candidate for preventing mobile phone use-related reproductive impairments.

    Full Text Available To obtain a better understanding of carbon cycle and accurate climate prediction models, highly accurate and temporal resolution observation of atmospheric CO2 is necessary. Differential absorption LIDAR (DIAL remote sensing is a promising technology to detect atmospheric CO2. However, the traditional DIAL system is the dual-wavelength DIAL (DW-DIAL, which has strict requirements for wavelength accuracy and stability. Moreover, for on-line and off-line wavelengths, the system’s optical efficiency and the change of atmospheric parameters are assumed to be the same in the DW-DIAL system. This assumption inevitably produces measurement errors, especially under rapid aerosol changes. In this study, a multi-wavelength DIAL (MW-DIAL is proposed to map atmospheric CO2 concentration. The MW-DIAL conducts inversion with one on-line and multiple off-line wavelengths. Multiple concentrations of CO2 are then obtained through difference processing between the single on-line and each of the off-line wavelengths. In addition, the least square method is adopted to optimize inversion results. Consequently, the inversion concentration of CO2 in the MW-DIAL system is found to be the weighted average of the multiple concentrations. Simulation analysis and laboratory experiments were conducted to evaluate the inversion precision of MW-DIAL. For comparison, traditional DW-DIAL simulations were also conducted. Simulation analysis demonstrated that, given the drifting wavelengths of the laser, the detection accuracy of CO2 when using MW-DIAL is higher than that when using DW-DIAL, especially when the drift is large. A laboratory experiment was also performed to verify the simulation analysis.

    Full Text Available The transition between the first abstract art – the one that precedes the second post-war period - and its later development can be investigated through Barnett Newman's “living rectangles”. Because Newman's pictures try to overcome both the objective idea of art - that still survives in the programmatic, geometrical abstraction of painters such as Mondrian and Klee - and the pure visibility of later formalist painters. Released from every prepackaged figure, emotion is commited though dangerously to language alone.

  7. Ecosystem approach and the Fuzzy logic: a dialectical proposal for information on Environmental Health Abordagem ecossistêmica e lógica Fuzzy: uma proposta dialética para o uso da informação em Saúde Ambiental

    Full Text Available The ever-growing production and the problematization of Environmental Health have shown the need to apprehend complex realities and deal with uncertainties from the most diversified instruments which may even incorporate local aspects and subjectivities by means of qualitative realities, while broadening the capacity of the information system. This paper presents a view on the reflection upon some challenges and possible convergences between the ecosystemic approach and the Fuzzy logic in the process of dealing with scientific information and decision-making in Environmental Health.O avanço da produção intelectual sobre Saúde e Ambiente tem demonstrado a necessidade de apreender realidades que são complexas, além de lidar com suas incertezas. Nesse sentido, os instrumentos utilizados deveriam incorporar aspectos subjetivos e qualitativos, além dos elementos de cunho quantitativo, ao retratar uma condição local. Esse artigo apresenta uma reflexão a respeito dos desafios e dos possíveis pontos de convergência entre uma abordagem ecossistêmica e a lógica Fuzzy nesse processo de lidar com a informação para apoio a tomada de decisão envolvendo Saúde e Ambiente.

  8. : The glocal bunker and its paradox: operational dialetic between "reclosure" and "openness" in advanced mediatic civilization. O bunker glocal e seu paradoxo: dialética operacional entre "refechamento" e "abertura" na civilização mediática avançada.

    Full Text Available in advanced mediatic civilization — In this article, the author reflects upon the sociohistorical signification of the glocal bunker today — the mediatic bunker of cyberculture (cyberspace, which, extending beyond the global and the local, within the very fabric of planetary glocaliza- tion, culturally rearticulates and reinforces the process of obliterated militarization of social life. His discussion dissects an autopoietic sociophenomenological and fundamental filigrain of the material and subjective experience of this bunker: a paradoxical intra-operational movement which simultaneously encompasses "reclosure" and "openness" in relation to the world, and particularly to alterity. This peculiar paradox conceals the way in which the collective and indi- vidual appropriation by the majority of digital networks is expressed in the sociohistorical and in quotidian life. In effect, internationally established cyber-overoptimistic discourse promotes the "openness" brought about by interactivity as the only fact worthy of attention in the current stage of the productive forces. The material and subjective "reclosure" it also represents is discarded as a mere historical exception, accident or minor inconvenience. The present study examines the naiveté of this epochal fallacy. "Openness" can only be understood if in inter-remission with the tendency for "reclosure". If, in cyberculture, there is no confinement or total atomization of the subject, neither is there an unquestionable horizon absolutely free to him. O artigo desdobra a reflexão do autor sobre a significação social-histórica do bunker glocal na atualidade — bunker mediático da cibercultura (o cyberspace que, vigorando para além do global e do local, já no tecido próprio da glocalização planetária, rearticula e reforça, cul- turalmente, o processo de militarização obliterada da vida social. A argumentação disseca uma filigrana sociofenomenológica autopoiética e fundamental da experiência material e subjetiva desse bunker: um movimento intra-operacional paradoxal no qual se encerram, simultanea- mente, "refechamento" e "abertura" em relação ao mundo e, em particular, à alteridade. Tal paradoxo peculiar recobre o modo pelo qual a apropriação coletiva e individual majoritária das redes digitais se expressa no social-histórico e na vida cotidiana. Com efeito, discursos ciberufanistas internacionalmente vigentes promovem a "abertura" trazida pela interatividade como o único fato digno de atenção no estágio atual das forças produtivas. O "refechamento" material e subjetivo que ele também representa fica descartado como mera excepcionalidade histórica, acidente ou mal menor. O artigo tensiona a ingenuidade política dessa falácia epocal. A "abertura" só pode ser compreendida se em interremissão com a tendência de "refechamen- to". Se, na cibercultura, inexiste confinamento ou atomização total do sujeito, tampouco se verifica aprumo inquestionável de horizonte absolutamente livre para ele.

  9. Dialética do desenvolvimento periférico: dependência, superexploração da força de trabalho e política econômica Dialectics of peripheral development: dependence, superexploitation of labor force and economic policy

    Full Text Available Este trabalho procura discutir as possibilidades de desenvolvimento na periferia da economia mundial, enfatizando dois aspectos. Em primeiro lugar, observa-se que as políticas econômicas neoliberais e a reestruturação produtiva foram formas encontradas pelo capital para responder à sua própria crise dos anos 1970, e que essas formas aprofundaram a condição de dependência das economias periféricas dentro da lógica mundial de acumulação capitalista. Em segundo lugar, constata-se que a única maneira de desenvolvimento capitalista na periferia, tendo em vista o aprofundamento da dependência, é a superexploração da força de trabalho. Por fim, argumenta-se que as alternativas para a periferia passam pela redução dessa superexploração da força de trabalho e/ou da luta contra a própria exploração capitalista da força de trabalho como forma de extração de excedente.This paper aims to discuss the possibilities of development in the periphery of the world economy emphasizing two points. Firstly, there is that the neoliberal economic policies and productive restructuring were forms found by capital to respond to its own crisis of 70's, and that these forms deepened the condition of dependency of peripheral economies within the logic of global capitalist accumulation. Secondly, it appears that the only way of capitalist development in the periphery, with a view to deepening dependence, is the superexploitation of labor force. Finally, it is argued that the alternatives to the periphery are the reduction of superexploitation of labor force and/or the fight against the capitalist exploitation of the labor force as a form of extraction of surplus.

    Full Text Available Com o objetivo de investigar a capacidade combinatória, bem como o efeito recíproco em dialelo envolvendo genótipos de milho doce e comum, avaliaram-se seis caracteres de interesse agronômico e industrial: altura de plantas, estande, porcentagem de espigas atacadas por pragas, teor de proteína no grão, peso médio de espiga sem palha e comprimento médio de espiga sem palha. Os valores dos quadrados médios referentes à capacidade geral de combinação ( e capacidade específica de combinação (Sij foram significativos para as características altura de planta, peso médio de espiga sem palha, comprimento médio de espiga sem palha e teor de proteína no grão, indicando a presença de efeitos gênicos aditivos e não aditivos no controle dos caracteres. Para peso médio de espiga sem palha e comprimento médio de espiga sem palha, as médias dos quadrados dos efeitos não diferiram, sugerindo a utilização de métodos intrapopulacionais ou interpopulacionais de melhoramento. Os genótipos Doce 13 e Sol da Manhã são os mais indicados para programas de melhoramento pelo comportamento dos valores de . Com base nos efeitos de Sij, o melhor híbrido foi Doce 13 X Sol da Manhã.The combining ability as well as reciprocal effect in diallel of sweet and regular corn genotypes was investigated for six agronomic and industrial characters: plant height, stand, percentage of ears attacked by insects, grain protein content, and average (mean dehusked ear length and weight. General Combining Ability ( and Specific Combining Ability (Sij mean square values were statistically significant when evaluating the following characters: plant height, average (mean dehusked ear length and weight, and grain protein content, indicating that additive and non-additive genetic effects control these characters. There was no statistical difference regarding mean square effects of average (mean dehusked ear length and weight characters suggesting the utilization of intra and interpopulational breeding methods. 'Doce 13' and 'Sol da Manhã' are among the most indicated genotypes for breeding programs due to observed trend of values. Based on specific combining ability estimates, the best hybrid originated from 'Doce 13' and 'Sol da Manhã' crossing.

    Full Text Available Este artigo resgata o avanço das análises teóricas sobre a influência do "modelo empresarial" no funcionamento do sistema educacional brasileiro, desde os anos da ditadura militar. Ressalta que as experiências práticas de gestão democrática da educação básica realizadas em administrações municipais de caráter democrático-popular necessitam ser avaliadas e expandidas para que se materializem as concepções avançadas de educação desenvolvidas pelos setores progressistas que são assimiladas e ressignificadas pelos grupos hegemônicos que atuam nas três instâncias de poder político e administrativo federal, estadual e municipal. São apresentados exemplos e sugestões de encaminhamento político-pedagógico para acirrar a contradição diante da política impositiva do governo, implementada sob a égide do Banco Mundial, de modo que os setores progressistas no cotidiano do funcionamento das escolas e dos sistemas de ensino resgatem os princípios, as concepções e metodologias que foram diluídos e negados no texto da "LDB oficial" para desenvolver o Plano Nacional de Educação.

    Full Text Available La investigación se centra en la caracterización de la actividad profesional del Contingente Médico Internacional “Henry Reeve”, especializado en situaciones de desastre y graves epidemias, tomando en cuenta el condicionamiento histórico social de la génesis del mismo, su desempeño profesional como parte de la sociedad revolucionaria cubana, así como su repercusión internacional; para lo mismo se realizó un estudio teórico, basado en la aplicación de los métodos históricos, de análisis y síntesis de fuentes documentales. El estudio permitió observar que, los servicios médicos no son únicamente un asunto de formación científica, es un asunto de política y de formación humanista. La posibilidad de su realización está condicionada histórica y socialmente de un modo concreto. La ciencia, ética y sociedad constituyen una unidad histórica que se asienta en un tipo cualitativo de política, por lo que la formación actual y futura de médicos y profesionales de la salud en nuestro país, deberá basarse en las necesidades de los campos, aldeas, barrios marginales y pobres de las ciudades del Tercer Mundo, consolidando los valores humanos necesarios en estos profesionales. Los miembros del Contingente Henry Reeve son portadores de profundos conocimientos científicos, de una fortaleza política, altos valores humanos y principios éticos inconfundibles, demostrados a través de estos años de revolución mediante la atención a nuestro pueblo, el cumplimiento de misiones internacionalistas y la colaboración médica en más de 100 países.This investigation is centred in the characterization of the professional activity of the International Medical Contingent ‘‘Henry Reeves'', specialized in disaster situations and serius epidemics, taking into account, its own social and historical nature, its professional acting as a part of the Cuban Revolutionary Society, as well as its international repercussion. For this reason a theorical study was carried out, based on the application of the historical methods of analysis and synthesis of documental sources. This study is allowed to observe that the medical services are not only a matter of scientific formation, its is a matter of policy and humanist formation. Science, ethics and society constitute a historical unit that settles a qualitative type of policy, for that reason the present and future formation of doctors and professionals of medicine should be based in the necessities of the people who live in the country side, villages and marginal neighbourhoods and the poors of the cities of the Third World, consolidating the necessary human values of these professionals. The members of the ‘Henry Reeves' Contingent have a mastery of deep scientific knowledge and political strength, high human values and unmistakable ethical principles, demonstrated through these years of Revolution by means of the attention to our people, carrying out international missions and the medical collaboration in more than 100 countries

La importante presencia de piezas musicales mexicanas que fueron integradas en esta ciudad hasta el punto de convertirse en nuevos estilos preflamencos propiamente gaditanos, es un fenómeno que no ha sido atendido en la literatura flamenca. El estudio del diálogo musical transatlántico entre Andalucía y México desde un enfoque etnomusicológico, es decisivo para la comprensión de los procesos de cambio musical producidos durante la etapa preflamenca, en la que Cádiz desempeñó un papel vertebrador.Over the centuries Cadiz has been a gateway for musics and dances from America.

    Full Text Available Taking into consideration various argumentation perspectives, the introduction of Modern and ContemporaryPhysics at High School level has been defended by various researchers. In the present qualitative nature research, weheard and interpreted ten High School physics teachers’ discourses, aiming to analyze how their initial education,regarding to Modern and Contemporary Physics, was based in a rationality which matches with the communicativeand the dialogical actions. Teachers of our sample were individually interviewed and, at that time, they had finishedtheir initial undergraduate program at least five years before. Teachers’ discourses interpretation was supported bysome French school discourse analysis’ concepts, Jürgen Habermas’ communicative action, Freire’s dialogicalaction, as well as teachers’ education research critical referential. The discourses interpretations evidenced that theseteachers’ education, with respect to Modern and Contemporary Physics, was mainly based in technical-instrumentalrationality basis. This perspective did not help teachers’ autonomy construction in order to work these subjects intheir classes, mainly in a perspective coherent with the teachers’ emancipation, producing reflexes in classroomphysics teaching. The study evidenciates the necessity of future teachers’ professors revise theirs teaching practice,as well studying other curricular structures, regarding to Modern and Contemporary Physics teaching.
