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.

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.

2005-12-01

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).

Occupational exposure as a painter is associated with DNA damage and development of cancer. Comet assay has been widely adopted as a sensitive and quantitative tool for DNA damage assessment at the individual cell level in populations exposed to genotoxics. The aim of this study was to assess the application of the high-throughput comet assay, to determine the DNA damage in car spray painters. The study population included 52 car spray painters and 52 unexposed subjects. A significant increase in the %TDNA median (p  0.05). The results showed an increase in DNA breaks in car spray painters exposed to organic solvents and paints; furthermore, they demonstrated the application of high-throughput comet assay in an occupational exposure study to genotoxic agents.

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.

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

Science.gov (United States)

Järvholm, Bengt; Burdorf, Alex

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.

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.

Exposure Characteristics of Construction Painters to Organic Solvents

Directory of Open Access Journals (Sweden)

Hyunhee Park

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.

Dynamic Properties of the Painter Street Overpass at Different Levels of Vibration

DEFF Research Database (Denmark)

Ventura, C. E.; Brincker, Rune; Andersen, P.

2005-01-01

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...

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.

Airborne UV DIAL Measurements of Ozone and Aerosols

Science.gov (United States)

Grant, William B.; Browell, Edward V.

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.

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.

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.

Efficient 1.6 Micron Laser Source for Methane DIAL

Science.gov (United States)

Shuman, Timothy; Burnham, Ralph; Nehrir, Amin R.; Ismail, Syed; Hair, Johnathan W.

2013-01-01

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.

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

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.

Low-temperature thermochronology of the Mt Painter Province, South Australia

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.

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.

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.

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.)

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

Development of an Airborne Micropulse Water Vapor DIAL

Science.gov (United States)

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

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.

Diode-laser-based water vapor differential absorption lidar (DIAL) profiler evaluation

Spuler, S.; Weckwerth, T.; Repasky, K. S.; Nehrir, A. R.; Carbone, R.

2012-12-01

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.

Multistage cancer models of bone cancer induction in beagles and mice by radium and plutonium, compared to humans

Energy Technology Data Exchange (ETDEWEB)

Bijwaard, H.; Brugmans, M. [RIVM-National Inst. for Public Health and the Environment, Lab. for Radiation Research, MA Bilthoven (Netherlands)

2005-07-01

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.)

Theodore I. King II, Ph.D, L.Ac.

2013-02-01

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.

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.

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.

Prevalence of technical mesothorium in self-luminous compounds used by New Jersey radium dial workers

International Nuclear Information System (INIS)

Keane, A.T.; Holtzmann, R.B.; Rundo, J.

1994-01-01

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

Multiple myeloma, leukemia, and breast cancer among the US radium dial workers

International Nuclear Information System (INIS)

Stebbings, J.H.; Lucas, H.F.; Stehney, A.F.

1984-01-01

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. 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

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.

Hugh Ramsay’s Self-Portrait: Reflections on a Spanish Master Painter

Directory of Open Access Journals (Sweden)

Jenny Beatriz Quijano Martínez

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.

The Center for Human Radiobiology has identified 5784 persons by name and type of exposure to 226 Ra and 228 Ra. Included are 4863 dial painters (mostly women) and non-laboratory employees of the radium dial industry, 410 laboratory workers, 399 persons who received radium for supposed therapeutic effects, and 112 in other categories. 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

Armit, R. J.; Ailleres, L.; Betts, P. G.; Schaefer, B. F.; Blaikie, T. N.

2014-10-01

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

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.

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.

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.

Preschool children adapt grasping movements to upcoming object manipulations: Evidence from a dial rotation task.

Herbort, Oliver; Büschelberger, Juliane; Janczyk, Markus

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.

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)

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

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.

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.

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

International Nuclear Information System (INIS)

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

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

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.

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

Science.gov (United States)

Abo, M.; Shibata, Y.; Nagasawa, C.

2017-12-01

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

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.

The Aboriginal painting movement has long been characterised by ‘remote stars’ whose seniority connotes the last generation to embody the full lexicon of pre-contact experience of language, law (tjukurrpa) and Country. Witness, for example, Emily Kame Kngwarreye, whose career—launched in her eighties—was all ‘late’; the taciturn old men guiding the middle-aged painters at Papunya in the early 1970s; or the last Nyikina speaker, Loongkoonan, who started painting in her nineties and is now brus...

Full Text Available We conducted a meta-analysis to quantitatively compare the association between occupation as a painter and the incidence or mortality from lung cancer. PubMed and the reference lists of pertinent publications were searched and reviewed. For the meta-analysis, we used data from 47 independent cohort, record linkage, and case-control studies (from a total of 74 reports, including > 11,000 incident cases or deaths from lung cancer among painters. Three authors independently abstracted data and assessed study quality. The summary relative risk (meta-RR, random effects for lung cancer in paint-ers was 1.35 [95% confidence interval (CI, 1.29-1.41; 47 studies] and 1.35 (95% CI, 1.21-1.51; 27 studies after controlling for smoking.

Lukas Klic,

2017-10-01

Full Text Available The Drawings of The Florentine Painters project created the first online database of Florentine Renaissance drawings by applying Linked Open Data (LOD techniques to a foundational text of the same name, first published by Bernard Berenson in 1903 (revised and expanded editions, 1938 and 1961. The goal was to make Berenson’s catalog information—still an essential information resource today—available in a machine-readable format, allowing researchers to access the source content through open data services. This paper provides a technical overview of the methods and processes applied in the conversion of Berenson’s catalog to LOD using the CIDOC-CRM ontology; it also discusses the different phases of the project, focusing on the challenges and issues of data transformation and publishing. The project was funded by the Samuel H. Kress Foundation and organized by Villa I Tatti, The Harvard University Center for Italian Renaissance Studies.

Dialética da pratica e ação sem prática

Ubaldo Puppi

1982-12-01

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.

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.

Adam Małkiewicz

2005-12-01

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

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.

Painters in the Splendor of Tunja: Naming Unrecognized Artists to Bring them out of Anonymity (XVI and XVII centuries

Directory of Open Access Journals (Sweden)

Laura Liliana Vargas Murcia

2017-07-01

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.

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.

A Dialógica como Princípio Metodológico Transdisciplinar na Pesquisa em Educação

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.

2005-01-01

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

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.

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)

Toxicity of 239Pu and 226Ra in young adult beagles: risk estimate in man

International Nuclear Information System (INIS)

Miller, S.C.

1985-01-01

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

Central nervous system tumors and related intracranial pathologies in radium dial workers

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 Travelogue Lacroma, Work of Stephanie, Crown Princess of Austria, and Anton Perko, Seascape Painter at the Court

Directory of Open Access Journals (Sweden)

Sanja Žaja Vrbica

2016-01-01

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

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

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.

Development and Deployment of a Compact Eye-Safe Scanning Differential absorption Lidar (DIAL) for Spatial Mapping of Carbon Dioxide for Monitoring/Verification/Accounting at Geologic Sequestration Sites

Energy Technology Data Exchange (ETDEWEB)

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.

Central nervous system tumours and related intracranial pathologies in radium dial workers

International Nuclear Information System (INIS)

Stebbings, J.H.; Semkiw, W.

1989-01-01

Among female radiation workers in the radium dial industry there is no overall excess of fatal brain or central nervous system tumours. A significant excess did appear, 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 tumours outside of the brain was observed, consistent with irradiation of nervous system tissue from adjacent bone. Excess tumours of the eye, pituitary or pineal did not occur. Early deaths from brain abscess or mastoiditis, coded as diseases of the nervous system and sense organs, were observed. (author)

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

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).

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.

Data from MIT and New Jersey studies were combined with data from the Center for Human Radiobiology, Argonne National Laboratory, to create a material of 2259 persons occupationaly exposed to radium. The population studied consisted of radium-dial painters, radium chemists, and persons who had received radium in past years in attempts to treat various medical conditions. Within a colony of beagle dogs at the LEHR, UCD, which received eight semi-monthly injections of 226 Ra were 28 dogs that received a dosage of 80 to 130 times maximum permissible skeletal burden for man (0.1 μCi 226 Ra).

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.

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

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.

Solvent exposure and related work practices amongst apprentice spray painters in automotive body repair workshops.

Science.gov (United States)

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.

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

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.

Metaheuristics for the dynamic stochastic dial-a-ride problem with expected return transports.

Schilde, M; Doerner, K F; Hartl, R F

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.

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

Science.gov (United States)

Abo, M.; Shibata, Y.; Nagasawa, C.

2017-12-01

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

Resumen: El objetivo del siguiente trabajo es explicar cómo la elaboración de una ontología de la naturaleza por parte de Merleau-Ponty se circunscribe en el intento de elaborar un pensamiento del ser que no haga de éste un elemento del pensamiento abstracto, sino que dé cuenta de la experiencia concreta del ser en el mundo. En este sentido, son fundamentales los conceptos de intercorporalidad, negatividad y dialéctica. Abstract: The aim of the following work is to explain how the elaborat...

[The apothecaries of the Saint-Honoré district of Paris in the 17th century. The apothecaries Antoine and Jacques Grégoire and Louis XIII’s first painter, Simon Vouet].

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. 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.

Finalmente, en base a los análisis realizados, se caracterizan los rasgos de la dialéctica. También se discute su unicidad y su carácter apriori en la Psicología del Desarrollo y en las Ciencias Humanas, justificándose su diversidad, en función de las temáticas que se indagan, así como a ciertos límites en el uso de esa categoría en la indagación empírica. Su implementación exige que adopte formas diferentes, pertinentes a los distintos problemas y focos teóricos.The present article analyses the signficance and relevance of dialectic in Piaget's and Vigotsky's psychological studies. On one hand, it highlights the common dialectical methodology present in units of analysis in research. On the other hand, it focuses on the peculiar features dialectic acquires within both authors' explanation of psychological development. 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.

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.

International Nuclear Information System (INIS)

Tehrani, M Kavosh; Jaafari, E; Mobashery, A; Mohammad, M Malek

2015-01-01

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.

van de Venne, Judy; Cerel, Julie; Moore, Melinda; Maple, Myfanwy

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.

Improving Standard Poststratification Techniques For Random-Digit-Dialing Telephone Surveys

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.

Survival times of pre-1950 US women radium dial workers

International Nuclear Information System (INIS)

Stehney, A.F.

1994-01-01

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

Long-term retention of radium in female former dial workers

Rundo, J.; Keane, A.T.; Essling, M.A.

1984-01-01

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

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.

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

Directory of Open Access Journals (Sweden)

Blasco Aznar, Pedro Luis

2009-12-01

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.

Halyo, N.

1983-01-01

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.

La práctica dialógica, dentro de las teorías de la educación comunicativa, va a enriquecer en gran medida la consecución del aprendizaje y la búsqueda del conocimiento en entornos virtuales donde la comunicación se favorece a través de redes sociales y herramientas comunicativas. Este estudio plantea la pregunta de si la comunidad universitaria está preparada para introducir el diálogo en su práctica educativa. Los resultados han sido analizados mediante la distribución de frecuencias simple desde una perspectiva cuantitativa. A través de un cuestionario se ha podido conocer qué entienden por diálogo profesores y estudiantes universitarios de educación presencial, semipresencial y virtual y cómo consideran que son sus diálogos y los de los demás en diferentes contextos. Se llega a conclusiones tan significativas como que no existe una concepción del diálogo basada en la argumentación sino que consideran que el diálogo se limita a un intercambio de opiniones.

A Dialética do Senhor e do Escravo como Fundamento da Sociologia enquanto Ciência Humana

Full Text Available O presente artigo busca derivar, a partir da Dialética do Senhor e do Escravo, da Fenomenologia do Espírito de Hegel, a sociologia moderna enquanto ciência essencialmente humana. 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.

, trajectory, station, grid, etc., which will be implemented in netCDF format. SeaDataNet is recommending ODV and NetCDF formats. 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

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

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.

Art, class and gender in Joseon dynasty Korea: representations of lower-class women by the scholar-painter Yun Duseo.

Science.gov (United States)

Chung, Saehyang P

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'.

Sonnabend, E.; Spiess, H.; Mays, C.W.

1986-01-01

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.)

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

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

Mechanistic models of bone cancer induction by radium and plutonium in animals compared to humans

International Nuclear Information System (INIS)

Bijwaard, H.

2006-01-01

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)

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)

Integrating stochastic time-dependent travel speed in solution methods for the dynamic dial-a-ride problem.

Science.gov (United States)

Schilde, M; Doerner, K F; Hartl, R F

2014-10-01

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.

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.

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

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.

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.

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.

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.

1.6 μm DIAL Measurement and Back Trajectory Analysis of CO2 Concentration Profiles in the Lower-Atmosphere

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.

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.

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

Compreensão dialética da ética revolucionária de Herbert Marcuse

Alberto Dias Gadanha

2017-05-01

Full Text Available A alteração qualitativa objetivo de uma ética revolucionária pressupõe a reciprocidade entre a decisão política enquanto asserção de parâmetros deontológicos a priori e a efetivação governamental de uma vida sem medo e sem miséria, uma vida de paz. Marcuse ao compreender que o objetivo a ser efetivado é uma vida sem medo e sem miséria supera tanto a eticidade deontológica caracterizada pelo imperativo categórico quanto a ética caracterizada pelo imperativo hipotético de determinação utilitarista. Ética revolucionária, como exposta por Herbert Marcuse na conferência de 1964 na Universidade de Kansas, é uma ética de superação dialética porque contempla por meio do imperativo implicativo tanto as exigências deontológicas, configuradas pela decisão política quanto as exigências utilitaristas configuradas pelo cálculo histórico de efetivação governamental da teleologia política.

Jean-Paul Sartre: La dialéctica ágil y paciente

Arribas, Sonia

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.

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

Lymphoblastogenesis in response to phytohemagglutinin in radium patients: quantitative aspects and reproducibility

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

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.

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

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.

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.

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.

Guiding Inspiratory Flow: Development of the In-Check DIAL G16, a Tool for Improving Inhaler Technique

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.

Neurologic effects of solvents in older adults. (UW retired worker study). Final performance report

Energy Technology Data Exchange (ETDEWEB)

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.

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.

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.

Research on the improvement of traditional dial instrument precision based on C8051F020.

2006-11-01

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.

La justicia social y la Utopía dialética: Discutiendo con Harvey sobre espacio público

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”.

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.

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

Biological effects of radium

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

Association between systemically administered radioisotopes and subsequent malignant disease

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

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.

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.

T urkish Women’s Figures and Clothing Properties Seen in Ottoman Term Orientalist Paintings

Full Text Available Among movements appearing in the painting art, the one most affecting the Turkish painting has become orientalism. Orientalism is defined as the West and Ea st’s effort to understand each other better. The 18 th century, when the Ottoman Empire is socially, economically and politically in the decline stage, is also the beginning of the orientalist movement. Great interest has been shown to Turkish and foreign painters in the terms of Sultan Selim III, Abdülmecid and Abdü laziz. Cultural interaction between painters has revealed an interest on using the Ottoman and East motifs not only in the side of the Ottoman and also in Western art. Topics of Orientalist painters are generally figure compositions and landscapes. That figure compositions take place in orientalism has caused the woman figure in the painting art to come to the forefront. In this research, it was focused on the women’s figures and clothes the orientalist painters used in their paintings while narrati ng their own, their cities and societies. Epochal figurative paintings of European and Turkish painters, who composed works on the Ottoman territories, were examined in terms of woman images, spaces, clothing, daily - use articles and other cultural items. T he women’s clothes’ model properties, ornamentations, accessories, fabrics and material types were emphasized. Since there wasn’t any style consensus in orientalist paintings, comments of painters on woman images and clothing were compared. In the research the descriptive method was used, and the data were got with the document scanning technique.

Hernández Castro, David

2009-12-01

Full Text Available The aporia resulting from Horkheimer and Adorno’s critique of the Dialectic of Enlightenment has been raised after the hermeneutic turn of the tradition started by Nietzsche and Heidegger. 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.

La aporía de la dialéctica de la Ilustración ha sido replanteada después de Horkheimer y Adorno por el giro hermenéutico de la tradición que nace con Nietzsche y Heidegger, y que básicamente propone un nuevo comienzo de la filosofía occidental volviendo a la raíz de la dualidad ontológica establecida por los presocráticos y sostenida por Aristóteles frente a la razón monológica de la Academia de Platón. A partir de una nueva interpretación de las éticas Eudemia y Nicomaquea, el autor afrontará una crítica de las visiones modernas de la teoría aristotélica de la virtud, incluida la de MacIntyre, para exponer un nuevo enfoque que vincula la práctica de la virtud con la democracia radical.

1991-01-01

The influence of color vision defects on pictorial art was studied using three methods. 1) From a theoretical standpoint, the possibilities of choice of the color-blind painter are determined by the nature of his color perception. Characteristic errors result from the fact that he has to choose between many hues which are different to a normal individual but which all look the same to him. 2) Evaluation of the clinical cases of painters with dyschromatopsias has shown evidence of the following: a) the color-blind painter makes mistakes according to the type of color defect; b) if the color-blind painter makes several copies of the same model, he makes different mistakes at each attempt; c) when several color-blind painters make copies of the same model, they also make different mistakes, even when they suffer from the same type of color vision defect. Preferences for some colored patterns were studied by means of a forced choice procedure and choices of color-blind individuals were often characteristic of their dyschromatopsia. Recent clinical case of acquired dyschromatopsia reported in the literature are discussed, as is a personal case of a painter suffering from tapeto-retinal degeneration. This was a severe dyschromatopsia with a neutral zone in purple (so-called scotpic axis, by Verriest's terminology). The painting of this artist tended to be monochromatic, mainly in green and green-blue colors. 3) Recent studies in art history have shown that only the romantic etcher Meryon was definitively color deficient. The more dubious cases of the Polish painter Grottger and of Eugène Carrière are discussed and conclusions are negative. Among acquired dyschromatopsias, there have been many recent papers devoted to cataract dyschromatopsias, concerning the cases of Rouault, Monet and Mary Cassatt. The hypothesis of a degree of chromatopsia or dyschromatopsia of toxic origin in the case of Van Gogh is also assessed. In conclusion, the problem of the relations between

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.

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

Toxicity ratios: Their use and abuse in predicting the risk from induced cancer

International Nuclear Information System (INIS)

Mays, C.W.; Taylor, G.N.; Lloyd, R.D.

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

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.

Internal dosimetry, past and future

International Nuclear Information System (INIS)

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

History of occupational exposure to natural radioisotopes

International Nuclear Information System (INIS)

Steinhausler, F.

1993-01-01

From pre-historic times miners represented the group which received, inadvertently, occupational exposure to natural radionuclides. 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

Full Text Available Constantine Calafateanu (1911-1978 is one of the most important Romanian painters of the twentieth century. He studied French literature at the Sorbonne, but he also regularly visited two painting studios: La Grande Chaumiere and Julien Academy. On returning to Romania he did some teaching work, therefore, he started exhibiting relatively late in life. His first solo exhibition took place in 1965. 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.

Feasibility Study of Multi-Wavelength Differential Absorption LIDAR for CO2 Monitoring

Chengzhi Xiang

2016-06-01

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 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.

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.

(Abstract   The following article is the result of a collaboration between a painter and a woman philosopher. They worked previously on an experimental documentary film about objects and art objects, which was realized at Palais de Tokyo. The painter had illustrated in black and white fictions of philosophy, written during a festival on lost films organized by UNdocumenta in South Korea, and then he made photographs of oil paintings of the English translation. This article about painting and philosophical ethics is their first common text. It aims to show that there is no interdiscipline or passage known between the philosophical work and the painting. The philosopher can not imitate the recognition of the painter nor the painter to repair the philosophical non-encounter. The question then is: What can ethics in this non-symmetrical space? Rather than being a product of philosophy, it is what organizes this space between recognition and non-encounter. It is an ethics for philosophy, rather than the other way around. Ethics force to greet the other philosophers without the grudge of the loss necessary to the invention and allows the painter to know the distances that make him feel the recognition. This ethical space is unknown and can not be covered by the artist's philosophy of access or pre-nomination by indexes. Ethics is this unknown, i.e. it is a sense-without-sign, it is without rules-said but process of indexation and acceptance of the loss.

A dialética do desespero em Kierkegaard e sua influência sobre conceito de alienação em Paul Tillich

Full Text Available A respectiva pesquisa procurou estabelecer a relação de influência da filosofia de Søren Kierkegaard sobre a construção teológica de Paul Tillich. Para tanto, utilizamos como pano de fundo ou estrutura argumentativa o conceito de Desespero humano de Kierkegaard, comparando-o ao conceito de Alienação do ser de Tillich. 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 The article discusses the dialogue established between the young public and museums, analyzing the contemporaneity of traditional museum discourse. 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.

Full Text Available The article explores the relation between two miniature painters: the Croatian Giulio Clovio and the Fleming Levina Teerlinc. The starting point of this research is a letter written in the 1540s, which is written by Annibal Caro in name of Giulio Clovio. The letter is addressed to a young nameless female miniature painter. This female miniature painter can be identified as Levina Teerlinc because of a corresponding characteristics and profile. The focal point of this letter is an exchange of self-portraits between Clovio and the female painter. Proof that it is Levina Teerlinc who sends Clovio her self-portrait is to be found in the testament of the Croatian artist, that reminds «il ritratto di Livinia meniatrice» or «the portrait of Livinia miniature painter».Historiography connected the event to the portrait of Giulio Clovio, painted by the hand of Sofonisba Anguissola. In this portrait the Croatian is depicted with a portrait miniature in his hand. Federico Zeri, owner of the portrait until 1998, believed that the miniature portrayed Levina Teerlinc. This present article argues that the miniature is a self-portrait of Sofonisba Anguissola. Evidence for this can be found in another portrait of this painter of Cremona. In the portrait of her master Bernardino Campi, Anguissola depicts Campi in the action of painting her portrait, which essentially is a self-portrait. In both paintings, the master paints a portrait of his pupil Sofonsiba: Bernardino Campi is her master for painting, while Giulio Clovio is her master for miniature painting. Clovio, just like Campi, is depicted in the act of painting, with the brush in his hand and his eye focussed on the viewer. Further, the article describes exhaustively the provenance of the portrait of Clovio. It particularly emphasises the typology of headgear the miniature painter wears and compares it with a similar sample worn by a contemporary Englishman. Finally, this study proposes to give some

Chromosome breakage in lymphocytes from humans with body burdens of 226Ra

1976-01-01

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

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

Schieve, L.A.; Davis, F.; Freels, S.

1997-01-01

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

Some studies have shown increased DNA damage among car painters, but other professionals working in auto body and paint shops have not been extensively assessed. The aim of this study was to assess DNA damage in different types of auto body shop workers by measuring micronucleus (MN) levels in exfoliated buccal cells. The mean number of cells with MN per 2000 exfoliated buccal cells was analyzed in three groups of male workers: auto body repair technicians, painters, and office workers (control group). All participants answered a questionnaire inquiring about age, smoking habits, alcohol consumption, work practices, occupational exposure time, job activities, and use of protective equipment. The mean number of cells with MN was 3.50 ± 1.50 in auto body painters, 3.91 ± 2.10 in auto body repair technicians, and 0.80 ± 0.78 in office workers, with a significant difference between the control group and the two other groups (p = 0.0001). Age, occupational exposure time, use of protective masks, alcohol consumption, and smoking habit did not affect MN results. The findings indicate that technicians and painters working in auto body shops are at risk for genotoxic damage, while office workers seem to be protected.

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.

Graffiti: subculture or vandalism

Full Text Available The article discusses the phenomenon of the modern graffiti in terms of subculture and vandalism. We denote the boundary between the concepts of vandalism in cultural and legal discourse. Study of scientific sources and method of participant observation allowed us to offer our own definition of graffiti. Particular attention is paid to the psychological portrait of the graffiti painters on the basis of empirical data obtained for the first time in our country. The study compared groups of young people involved in graffiti and in legal fine arts. The study revealed the psychological characteristics of graffiti painters and identified the main factors that keep young people in the subculture. Graffiti subculture itself is not considered as a criminal community, but as a communicative field within which young people decide their age-specific problems. Accordingly, we proposed penalties for graffiti painters considering their psychological characteristics.

Full Text Available We study on-line version of size-Ramsey numbers of graphs defined via a game played between Builder and Painter: in one round Builder joins two vertices by an edge and Painter paints it red or blue. The goal of Builder is to force Painter to create a monochromatic copy of a fixed graph H in as few rounds as possible. The minimum number of rounds (assuming both players play perfectly is the on-line Ramsey number r(H of the graph H. We determine exact values of r(H for a few short paths and obtain a general upper bound r(Pn ≤ 4n-7. We also study asymmetric version of this parameter when one of the target graphs is a star Sn with n edges. We prove that r(Sn,H≤n ·e(H when H is any tree, cycle or clique.

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.

A powerful and reliable tool for range-resolved remote sensing of gas concentrations that has proven its capabilities in a variety of studies is the differential absorption lidar (DIAL). Differential absorption lidar (DIAL) is frequently used for atmospheric gas monitoring to detect impurities such as nitrogen dioxide, sulfur dioxide, iodine, and ozone. DIAL can measure air pollutant concentrations with a high spatial resolution by adopting two laser systems with different degrees of absorption between the two different wavelengths. The absorption of the reference wavelength is very weak, while the absorption of the other wavelength is very strong. In this paper, we measured the limit of detection capability of our designed DIAL system. The DIAL measurements were performed using a target iodine cell in the laboratory. We confirmed that the concentration of iodine gas ratio increased after the laser passed through the iodine cell. The system of DIAL(Differential Absorption Lidar) was effective to detect the iodine gas. We obtained the signals from the iodine target cell and the lidar signal from the iodine target cell was proportional to frequency locking ratios.

Effetto Tintoretto: Longhi, Sartre, Bernhard

Directory of Open Access Journals (Sweden)

Stefania Rutigliano

2011-05-01

Full Text Available Searching for the core of Tintoretto’s ‘modern’ thinking and for his attractivity, the issue touches two different perspectives on the Venetian painter. Different in genre but not so in content, Sartre’s essays on Tintoretto’s paintings and Bernhard’s novel Ancient Masters look at the new relation between the painter and his public as a fundamental feature in his way of working. The painter’s aspiration after changing the city, its people and the same rules of the art market is not his only way to go beyond the limits. Also useful for this aim is the theme of perception, of looking, that, peculiarly developed by Tintoretto, as Sartre displays, becomes also an interesting aspect in Bernhard’s novel. In the presence of a rather nonfamous portrait by the Venetian painter, The Man with a white Beard, the novel goes beyond and debates on great general artistic questions: originality, masterpiece, tradition and critic.

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

International Nuclear Information System (INIS)

Richardson, R.B.

2007-01-01

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.

The response to chemical stimuli (chemical responsiveness) and the increases in respiratory drive required for arousal (arousal threshold) and for opening the airway without arousal (effective recruitment threshold) are important determinants of ventilatory instability and, hence, severity of obstructive apnea. We measured these variables in 21 obstructive apnea patients (apnea-hypopnea index 91 +/- 24 h(-1)) while on continuous-positive-airway pressure. During sleep, pressure was intermittently reduced (dial down) to induce severe hypopneas. Dial downs were done on room air and following approximately 30 s of breathing hypercapneic and/or hypoxic mixtures, which induced a range of ventilatory stimulation before dial down. Ventilation just before dial down and flow during dial down were measured. Chemical responsiveness, estimated as the percent increase in ventilation during the 5(th) breath following administration of 6% CO(2) combined with approximately 4% desaturation, was large (187 +/- 117%). Arousal threshold, estimated as the percent increase in ventilation associated with a 50% probability of arousal, ranged from 40% to >268% and was chemical drive. Effective recruitment threshold, estimated as percent increase in pre-dial-down ventilation associated with a significant increase in dial-down flow, ranged from zero to >174% and was chemical drive, but instability results because of a low arousal threshold and a brisk increase in drive following brief reduction in alveolar ventilation.

The poetry of John Ruskin – which amounts to a surprisingly large body of work, mostly written in the 1830s and 1840s – reveals the stirrings of the moral perceptual attitude that would emerge with such distinctive force in Modern Painters, yet one guided by the influences of Keats, Shelley and Byron as much as the natural theology of Wordsworth (despite Modern Painters taking its epigraph from The Excursion).

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.

DeYoung, Russell J.; Mead, Patricia F.

2004-01-01

This system study proposes the deployment of a water vapor Differential Absorption LIDAR (DIAL) system on an Altair unmanned aerial vehicle (UAV) platform. The Altair offers improved payload weight and volume performance, and longer total flight time as compared to other commercial UAV's. This study has generated a preliminary design for an Altair based water vapor DIAL system. The design includes a proposed DIAL schematic, a review of mechanical challenges such as temperature and humidity stresses on UAV deployed DIAL systems, an assessment of the available capacity for additional instrumentation (based on the proposed design), and an overview of possible weight and volume improvements associated with the use of customized electronic and computer hardware, and through the integration of advanced fiber-optic and laser products. The results of the study show that less than 17% of the available weight, less than 19% of the volume capacity, and approximately 11% of the electrical capacity is utilized by the proposed water vapor DIAL system on the Altair UAV.

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.

The applicability of a KTA crystal-based laser system with optical parametric oscillators (OPO) generation to lidar sounding of the atmosphere in the spectral range 3-4 μm is studied in this work. A technique developed for lidar sounding of trace atmospheric gases (TAG) is based on differential absorption lidar (DIAL) method and differential optical absorption spectroscopy (DOAS). The DIAL-DOAS technique is tested to estimate its efficiency for lidar sounding of atmospheric trace gases. The numerical simulation performed shows that a KTA-based OPO laser is a promising source of radiation for remote DIAL-DOAS sounding of the TAGs under study along surface tropospheric paths. A possibility of using a PD38-03-PR photodiode for the DIAL gas analysis of the atmosphere is shown.

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

Full Text Available In the tropics, deep convection is the major source of uncertainty in water vapor transport to the upper troposphere and into the stratosphere. Although accurate measurements in this region would be of first order importance to better understand the processes that govern stratospheric water vapor concentrations and trends in the context of a changing climate, they are sparse because of instrumental shortcomings and observational challenges. Therefore, the Falcon research aircraft of the Deutsches Zentrum für Luft- und Raumfahrt (DLR flew a zenith-viewing water vapor differential absorption lidar (DIAL during the Tropical Convection, Cirrus and Nitrogen Oxides Experiment (TROCCINOX in 2004 and 2005 in Brazil. The measurements were performed alternatively on three water vapor absorption lines of different strength around 940 nm. These are the first aircraft DIAL measurements in the tropical upper troposphere and in the mid-latitudes lower stratosphere. Sensitivity analyses reveal an accuracy of 5% between altitudes of 8 and 16 km. This is confirmed by intercomparisons with the Fast In-situ Stratospheric Hygrometer (FISH and the Fluorescent Advanced Stratospheric Hygrometer (FLASH onboard the Russian M-55 Geophysica research aircraft during five coordinated flights. The average relative differences between FISH and DIAL amount to −3%±8% and between FLASH and DIAL to −8%±14%, negative meaning DIAL is more humid. The average distance between the probed air masses was 129 km. The DIAL is found to have no altitude- or latitude-dependent bias. A comparison with the balloon ascent of a laser absorption spectrometer gives an average difference of 0%±19% at a distance of 75 km. Six tropical DIAL under-flights of the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS on board ENVISAT reveal a mean difference of −8%±49% at an average distance of 315 km. While the comparison with MIPAS is somewhat less significant due to poorer

Predictions of silicon avalanche photodiode detector performance in water vapor differential absorption lidar

Kenimer, R. L.

1988-01-01

Performance analyses are presented which establish that over most of the range of signals expected for a down-looking differential absorption lidar (DIAL) operated at 16 km the silicon avalanche photodiode (APD) is the preferred detector for DIAL measurements of atmospheric water vapor in the 730 nm spectral region. The higher quantum efficiency of the APD's, (0.8-0.9) compared to a photomultiplier's (0.04-0.18) more than offsets the higher noise of an APD receiver. In addition to offering lower noise and hence lower random error the APD's excellent linearity and impulse recovery minimize DIAL systematic errors attributable to the detector. Estimates of the effect of detector system parameters on overall random and systematic DIAL errors are presented, and performance predictions are supported by laboratory characterization data for an APD receiver system.

Full Text Available The applicability of a KTA crystal-based laser system with optical parametric oscillators (OPO generation to lidar sounding of the atmosphere in the spectral range 3–4 μm is studied in this work. A technique developed for lidar sounding of trace atmospheric gases (TAG is based on differential absorption lidar (DIAL method and differential optical absorption spectroscopy (DOAS. The DIAL-DOAS technique is tested to estimate its efficiency for lidar sounding of atmospheric trace gases. The numerical simulation performed shows that a KTA-based OPO laser is a promising source of radiation for remote DIAL-DOAS sounding of the TAGs under study along surface tropospheric paths. A possibility of using a PD38-03-PR photodiode for the DIAL gas analysis of the atmosphere is shown.

La ejercida sobre los pintores españoles siempre se ha asumido como de forma directa debido a las obras de su mano hechas para la corte. Sin embargo, no sólo va a ser a través de las obras del maestro de Cadore y las copias, tanto italianas como las hechas en territorio peninsular, las que van a influir en el gusto por sus composiciones, sino también a través de las copias hechas por pintores flamencos que llegan a la península. Muchas de estas obras flamencas siguiendo a Tiziano han sido admiradas como originales, y otras han sido demandadas a estos pintores septentrionales debido a su cuidado en el detalle y su capacidad de reproducción. Aquí analizamos dos ejemplos de este tipo, el primero se trata de una Magdalena de Gillis Coignet que estuvo atribuida al italiano, y el segundo la labor como copistas de Tiziano de Pablo Schepers y Roland de Moys en el entorno del duque de Villahermosa. Titian's influence in European painters of the sixteenth century is well known. The influence exerted on Spanish painters has always been assumed as directly because of the works of his hand made for the court. However, it will not only be through that works of the master of Cadore and his copies, as much Italians than those made in peninsular territory, which are going to have influence over the taste for his compositions, but also through copies made by Flemish painters who arrived at the peninsula. Many of these Flemish works following Tiziano´s compositions have been admired as originals, and others have been asked for them to these northern painters because of their care in details and their reproductive skills. This article analyzes two examples of both types, the first one is a Mary Magdalen by Gillis Coignet that was attributed to the Italian painter, and the second the work as copyists of Titian by Pablo Schepers and Rolan de Mois in the milieu of the Duke of

Atmospheric water vapor is a greenhouse gas that is known to be a significant driver of weather and climate. Several National Research Council (NRC) reports have highlighted the need for improved water vapor measurements that can capture its spatial and temporal variability as a means to improve weather predictions. Researchers at Montana State University (MSU) and the National Center for Atmospheric Research (NCAR) have developed an eye-safe diode laser based micro-pulse differential absorption lidar (MP-DIAL) for water vapor profiling in the lower troposphere. The MP-DIAL is capable of long term unattended operation and is capable of monitoring water vapor in the lower troposphere in most weather conditions. Two MP-DIAL instruments are currently operational and have been deployed at the Front Range Air Pollution and Photochemistry Experiment (FRAPPE), the Plains elevated Convection at Night (PECAN) experiment, the Perdigão experiment, and the Land Atmosphere Feedback Experiment (LAFE). For each of these field experiments, the MP-DIAL was run unattended and provided near-continuous water vapor profiles, including periods of bright daytime clouds, from 300 m above the ground level to 4 km (or the cloud base) with 150 m vertical resolution and 5 minute temporal resolution. Three additional MP-DIAL instruments are currently under construction and will result in a network of five eye-safe MP-DIAL instruments for ground based weather and climate research experiments. Taking advantage of the broad spectral coverage and modularity or the diode based architecture, a high spectral resolution lidar (HSRL) measurement capabilities was added to the second MP-DIAL instrument. The HSRL capabilities will be operational during the deployment at the LAFE field experiment. The instrument architecture will be presented along with examples of data collected during recent field experiments.

Water vapor differential absorption lidar development and evaluation

Browell, E. V.; Wilkerson, T. D.; Mcllrath, T. J.

1979-01-01

A ground-based differential absorption lidar (DIAL) system is described which has been developed for vertical range-resolved measurements of water vapor. The laser transmitter consists of a ruby-pumped dye laser, which is operated on a water vapor absorption line at 724.372 nm. Part of the ruby laser output is transmitted simultaneously with the dye laser output to determine atmospheric scattering and attenuation characteristics. The dye and ruby laser backscattered light is collected by a 0.5-m diam telescope, optically separated in the receiver package, and independently detected using photomultiplier tubes. Measurements of vertical water vapor concentration profiles using the DIAL system at night are discussed, and comparisons are made between the water vapor DIAL measurements and data obtained from locally launched rawinsondes. Agreement between these measurements was found to be within the uncertainty of the rawinsonde data to an altitude of 3 km. Theoretical simulations of this measurement were found to give reasonably accurate predictions of the random error of the DIAL measurements. Confidence in these calculations will permit the design of aircraft and Shuttle DIAL systems and experiments using simulation results as the basis for defining lidar system performance requirements

High Power OPO Laser and wavelength-controlled system for 1.6μm CO2-DIAL

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

Full Text Available Raden Saleh is a 19th century Indonesian painter who had the opportunity to master the European paintings in his time. He was born in Terbaya, Semarang on 1807 from a noble family. He then studied painting under the Belgian painter A.A.J. Payen who was assigned by Dutch colonial ruler to capture Indonesian scenery. After studied for some times in Indonesia, he began to travel to Netherlands, Germany, France, and several other European countries and chiseled his name as a famous Romantic painter both in Europe and in Indonesia. This research began from a predicament on how far Romanticism has its influence on Raden Saleh‟s paintings. Romanticism in Raden Saleh‟s works not only characterized by the visual and themes, but also embedded in Raden Saleh‟s ideas and attitude. Raden Saleh, at that time, developed a distinctive style and themes under the Romantic spirit which is mostly a depiction about hunting scenes, allegorical landscape, and dramatic scenes that involves human‟s emotion. Nevertheless the influence of Romanticism is to be found more on Raden Saleh‟s ideas and attitude, such as the idea about the grandeur of nature, exoticism, orientalism, individual freedom, and struggle for liberty.

A comparison of mixing depths observed by ground-based wind profilers and an airborne lidar

The mixing depth is one of the most important parameters in air pollution studies because it determines the vertical extent of the `box` in which pollutants are mixed and dispersed. During the 1995 Southern Oxidants Study (SOS95), scientists from the National Oceanic and Atmospheric Administration Environmental Technology Laboratory (NOAA/ETL) deployed four 915-MHz boundary-layer radar/wind profilers (hereafter radars) in and around the Nashville, Tennessee metropolitan area. Scientists from NOAA/ETL also operated an ultraviolet differential absorption lidar (DIAL) onboard a CASA-212 aircraft. Profiles from radar and DIAL can be used to derive estimates of the mixing depth. The methods used for both instruments are similar in that they depend on information derived from the backscattered power. However, different scattering mechanisms for the radar and DIAL mean that different tracers of mixing depth are measured. In this paper we compare the mixing depth estimates obtained from the radar and DIAL and discuss the similarities and differences that occur. (au)

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.

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.

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.

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

Pathway to a paradigm: the linear nonthreshold dose-response model in historical context. The American Academy of Health Physics 1995 Radiology Centennial Hartman Oration.

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.

Comics Journalism and Fine Art: War, Massacre, and The Individual, in works of Pieter Bruegel, Joe Sacco and Otto Dix

Directory of Open Access Journals (Sweden)

Sara Owj

2017-02-01

Full Text Available As a pioneer of Comics Journalism, Joe Sacco’s works have been linked to conflict studies, migration, education, and so on. But despite references that Sacco makes to 16th Century master painter, Pieter Bruegel, and 20th century New Objectivity painter Otto Dix in his interviews, there have been few studies on the potential link between comics of Sacco and works of these masters of fine art. In this study I explore this connection by examining the questions of war, individuality and portrayal of massacre in paintings of Bruegel and Dix and journalistic comics of Sacco. My greater aim is to demonstrate the potential of further comparative studies between arts and comics journalism, especially between Renaissance and modern artists.

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.

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

Dialéctica y Libertad

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 OBJETIVO: Compreender diferentes lógicas de autonomia presentes nos conflitos entre prescrições cirúrgicas e expectativas de pacientes com diagnóstico de câncer. 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.

The purpose of this study was to evaluate the usefulness of tibial reduction during dial test for clinical detection of underestimated posterolateral rotatory instability (PLRI) in combined posterior cruciate ligament (PCL)-posterolateral corner (PLC) deficient knee in terms of external rotation laxity and clinical outcomes. Twenty-one patients who classified as grade I PLRI using dial test with subluxated tibia, but classified as grade II with tibial reduction evaluated retrospectively. The mean follow-up was 39.3 months (range 24-61 months). Each patient was evaluated by the following variables: posterior translation and varus laxity on radiograph, KT-1000 arthrometer, dial test (reduced and subluxated position), International Knee Documentation Committee, Orthopädische Arbeitsgruppe Knie scoring system and Tegner activity scale. There were significant improvements in posterior tibial translation (8.6 ± 2.0 to 2.1 ± 1.0 mm; P application of reduction of posteriorly subluxated tibia during the dial test was essential for an appropriate treatment of underestimated PLRI in combined PCL-PLC deficient knee.

This study identifies technologies required to extend the capabilities of airborne light detection and ranging (lidar) systems and establish the feasibility of autonomous space-based lidars. Work focused on technologies that enable the development of a lightweight, low power, rugged and autonomous Differential Absorption Lidar (DIAL) instruments. Applications for airborne or space-based DIAL include the measurement of water vapor profiles in support of climate research and processing-plant emissions signatures for environmental and nonproliferation monitoring. A computer-based lidar performance model was developed to allow trade studies to be performed on various technologies and system configurations. It combines input from the physics (absorption line strengths and locations) of the problem, the system requirements (weight, power, volume, accuracy), and the critical technologies available (detectors, lasers, filters) to produce the best conceptual design. Conceptual designs for an airborne and space-based water vapor DIAL, and a detailed design of a ground-based water vapor DIAL demonstration system were completed. Future work planned includes the final testing, integration, and operation of the demonstration system to prove the capability of the critical enabling technologies identified

Fuir la complétude ou Le métarécit intermédial des Faux-monnayeurs

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.

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 The new Grohar’s room in the Škofja Loka Mu¬seum that is located in a more than a thousand years old town, some kilometres northwest of Ljubljana, Slove¬nia, represents one of the new possibilities to popularize old local history. Ivan Grohar (1867−1911 is one of the four well-known Slovenian painters from the beginning of the 20th century, together with Rihard Jakopič, Matija Jama and Matej Sternen. These Slovenian painters are the founders of Impressionism within the modern style. Škofja Loka became the so called Slovenian “Barbizon” (i.e. French village near Fontainebleau, once the settle-ment of painters and this art and old tradition inspired another Slovenian (music artist Oskar Dev (1868−1932, who composed some of his musical works (songs and choirs in Škofja Loka, too. His and Grohar’s period in Škofja Loka resulted in some extraordinary art works i.e. paintings and musical works. They both were inspired by the countryside that reflected on their works. This is now one of the new Slovenian’s challenges of museology and musicology in an interdisciplinary and multidisciplinary approach so the art of painting and music could be a benefit for the visitors of this and other museums.

Practical Design Guidelines for Fugitive Gas Detection from Unmanned Aerial Vehicles

Science.gov (United States)

Tandy, William D., Jr.

Simulation, design, and analysis are combined in this effort to realize a UAV-scale instrument for fugitive gas detection. The contributing material to the industry begins by extending and correlating an integrated Gaussian plume model useful for instrument predictions and trade studies, regardless of the instrument type or molecule of interest. A variety of generally applicable plots are produced from this foundation, including receiver operator curves for leak rate detectability vs. wind speed, beam diameter vs. leak rate detectability, and plots for required scan densities. The atmospheric and instrument parameter trade studies are followed by hardware-specific analyses applicable to differential absorption lidar (DIAL) instruments. A synopsis of the lessons learned from hands-on experiences in the lab further define the design space for DIAL sensors. The dissertation culminates in the detailed design and analysis of two DIAL instrument concepts. The conclusion is that a DIAL instrument capable of reliably detecting a 50 SCFH plume in winds speeds up to 7 mph is on the threshold of being achievable on a quadcopter platform. Of special note is that the effort was funded by a Pipeline and Hazardous Materials Safety Administration grant and performed in collaboration with Ball Aerospace & Technologies.

The lead-poisoned genius: saturnism in famous artists across five centuries.

Science.gov (United States)

Montes-Santiago, Julio

2013-01-01

Lead poisoning (saturnism) has been present throughout the history of mankind. In addition to possible ingestion from contaminated food, one of the most important ways in which poisoning caused morbid processes was by occupational exposure. This exposition was pandemic in the Roman Empire, and it has been claimed that it contributed to its fall, but it also caused numerous epidemics in Western countries until the nineteenth century. In the case of artists, and since the Renaissance period, this toxicity has been called painter's colic or painter's madness. The latter term is partly due to the mental disorders displayed by some of the great masters, including Michelangelo and Caravaggio, although it was long recognized that even house and industrial painters were prone to the disorder. This chapter examines the historical evidence of recognition of such toxicity and discusses the controversies raised by the possibility of professional lead poisoning in great artists. In addition to those mentioned above, many other artists across several centuries will be discussed, some being Rubens, Goya, Fortuny, Van Gogh, Renoir, Dufy, Klee, Frida Kahlo, and Portinari. This chapter also briefly mentions the possibility of lead poisoning in two famous composers: Beethoven and Handel. Whether suffering from lead poisoning or not, about which we cannot always be sure, we should still highlight and admire such geniuses fighting their disorders to bequeath us their immortals works. © 2013 Elsevier B.V.

Full Text Available FUNDAMENTO: Os indivíduos com insuficiência renal crônica terminal estão sujeitos a um elevado estresse cardíaco pelo carácter repetitivo e intermitente da terapia dialítica. As alterações na sístole elétrica ventricular induzidas pela necessária terapia dialítica são um contributo importante na predição da ocorrência de morte súbita arrítmica na insuficiência renal crônica terminal. OBJETIVO: O objetivo principal desta investigação é avaliar o comportamento da repolarização ventricular em face da terapia dialítica, mediante o estudo do intervalo QTc e dispersão do QTc. MÉTODOS: A amostra em estudo inclui 47 indivíduos sujeitos a hemodiálise (61,7% do sexo masculino e 38,3% do sexo feminino com idade média de 66,79 ± 13,16 anos. Todos os indivíduos foram sujeitos a três eletrocardiogramas realizados em três momentos durante a terapia dialítica (pré, durante e após a sessão, sendo posteriormente analisada a sístole elétrica ventricular. RESULTADOS: Ocorreu um aumento do intervalo QTc máximo e da dispersão do QTc associado à terapia dialítica. Aliado ao aumento desses intervalos ocorreu um aumento do número de indivíduos com critérios eletrocardiográficos para hipertrofia ventricular esquerda, registando-se no período pós-diálise uma média superior do intervalo QTc máximo (473 ± 27,63 mseg e da dispersão do QTc (58,95 ± 18,87 mseg desses indivíduos, comparativamente aos indivíduos sem HVE, 455,21 ± 26,85 mseg e 44 ± 16,41 mseg, respectivamente. CONCLUSÃO: O presente estudo confirmou um aumento do intervalo QTc e da dispersão do QTc associado à terapia dialítica. Esse aspecto reforça a dependência da repolarização ventricular em relação ao equilíbrio hídrico e eletrolítico e sugere um perfil de maior vulnerabilidade arrítmica associada à terapia dialítica.

Real-Time Video Stylization Using Object Flows.

Science.gov (United States)

Lu, Cewu; Xiao, Yao; Tang, Chi-Keung

2017-05-05

We present a real-time video stylization system and demonstrate a variety of painterly styles rendered on real video inputs. The key technical contribution lies on the object flow, which is robust to inaccurate optical flow, unknown object transformation and partial occlusion as well. Since object flows relate regions of the same object across frames, shower-door effect can be effectively reduced where painterly strokes and textures are rendered on video objects. The construction of object flows is performed in real time and automatically after applying metric learning. To reduce temporal flickering, we extend the bilateral filtering into motion bilateral filtering. We propose quantitative metrics to measure the temporal coherence on structures and textures of our stylized videos, and perform extensive experiments to compare our stylized results with baseline systems and prior works specializing in watercolor and abstraction.

2017-10-15

We report on the capability of a direct detection differential absorption lidar (DIAL) for range resolved and integrated path (IPDIAL) remote sensing of CO 2 in the atmospheric boundary layer (ABL). The laser source is an amplified nested cavity optical parametric oscillator (NesCOPO) emitting approximately 8 mJ at the two measurement wavelengths selected near 2050 nm. Direct detection atmospheric measurements are taken from the ground using a 30 Hz frequency switching between emitted wavelengths. Results show that comparable precision measurements are achieved in DIAL and IPDIAL modes (not better than a few ppm) on high SNR targets such as near range ABL aerosol and clouds, respectively. Instrumental limitations are analyzed and degradation due to cloud scattering variability is discussed to explain observed DIAL and IPDIAL limitations.

The Japanese jewel beetle: a painter's challenge

International Nuclear Information System (INIS)

Schenk, Franziska; Wilts, Bodo D; Stavenga, Doekele G

2013-01-01

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.

Isocyanate exposure was evaluated in 33 spray painters from 25 Washington State autobody shops. Personal breathing zone samples (n = 228) were analyzed for isophorone diisocyanate (IPDI) monomer, 1,6-hexamethylene diisocyanate (HDI) monomer, IPDI polyisocyanate, and three polyisocyanate forms of HDI. The objective was to describe exposures to isocyanates while spray painting, compare them with short-term exposure limits (STELs), and describe the isocyanate composition in the samples. The composition of polyisocyanates (IPDI and HDI) in the samples varied greatly, with maximum amounts ranging from up to 58% for HDI biuret to 96% for HDI isocyanurate. There was a significant inverse relationship between the percentage composition of HDI isocyanurate to IPDI and to HDI uretdione. Two 15-min STELs were compared: (1) Oregon's Occupational Safety and Health Administration (OR-OSHA) STEL of 1000 μg/m3 for HDI polyisocyanate, and (2) the United Kingdom's Health and Safety Executive (UK-HSE) STEL of 70 μg NCO/m3 for all isocyanates. Eighty percent of samples containing HDI polyisocyanate exceeded the OR-OSHA STEL while 98% of samples exceeded the UKHSE STEL. The majority of painters (67%) wore half-face air-purifying respirators while spray painting. Using the OROSHA and the UK-HSE STELs as benchmarks, 21% and 67% of painters, respectively, had at least one exposure that exceeded the respirator's OSHA-assigned protection factor. A critical review of the STELs revealed the following limitations: (1) the OR-OSHA STEL does not include all polyisocyanates, and (2) the UK-HSE STEL is derived from monomeric isocyanates, whereas the species present in typical spray coatings are polyisocyanates. In conclusion, the variable mixtures of isocyanates used by autobody painters suggest that an occupational exposure limit is required that includes all polyisocyanates. Despite the limitations of the STELs, we determined that a respirator with an assigned protection factor of 25 or

Two 15-min STELs were compared: (1) Oregon's Occupational Safety and Health Administration (OR-OSHA) STEL of 1000 μg/m(3) for HDI polyisocyanate, and (2) the United Kingdom's Health and Safety Executive (UK-HSE) STEL of 70 μg NCO/m(3) for all isocyanates. Eighty percent of samples containing HDI polyisocyanate exceeded the OR-OSHA STEL while 98% of samples exceeded the UK-HSE STEL. The majority of painters (67%) wore half-face air-purifying respirators while spray painting. Using the OR-OSHA and the UK-HSE STELs as benchmarks, 21% and 67% of painters, respectively, had at least one exposure that exceeded the respirator's OSHA-assigned protection factor. A critical review of the STELs revealed the following limitations: (1) the OR-OSHA STEL does not include all polyisocyanates, and (2) the UK-HSE STEL is derived from monomeric isocyanates, whereas the species present in typical spray coatings are polyisocyanates. In conclusion, the variable mixtures of isocyanates used by autobody painters suggest that an occupational exposure limit is required that includes all polyisocyanates. Despite the limitations of the STELs, we determined that a respirator with an assigned protection factor of 25 or

‘Afro-Ghanaian influences in Ghanaian paintings’

Directory of Open Access Journals (Sweden)

Kwame Amoah Labi

2013-12-01

Full Text Available Easel painting is a foreign art form whose materials and techniques were introduced by the Europeans into the Gold Coast, now Ghana, in the first decades of the twentieth century during the period of European modern art. Since its introduction as an academic discipline, concepts identified as Ghanaian have been incorporated into it. Hence there is the need for scholarly debate on this subject to define a framework for a discourse on the histories and receptions of Ghanaian painting. This article discusses Ghanaian easel painting by examining some African and non-African voices in the discourse on modern and contemporary African art, its early teaching methods and philosophy, and their impact on modern and post-colonial painters. To what degree did early instructors succeed in their insistence on students incorporating Ghanaian aesthetics and principles in their studies, and what impact has this had on subsequent painters?

The bay of Cattaro (Kotor school of icon-painting 1680-1860

2014-01-01

Full Text Available Relying on post-Byzantine tradition, eleven painters from five generations of the Dimitrijević-Rafailović family, accompanied by Maksim Tujković, painted several thousand icons and several hundred iconostases between the late seventeenth and the second half of the nineteenth century. They worked in major Orthodox Christian monasteries in Montenegro, Kosovo and Metohija, Bosnia and Herzegovina and Dalmatia, but their works can mostly be found in modest village churches in the Bay of Kotor (Cattaro and on the South Adriatic coast. The decoration of these churches was financially supported by the local population headed by elders. Along with a reconstruction of their biographies and a chronological overview of their major works, this paper seeks to trace stylistic changes in the Bay of Kotor school of icon-painting. While simply varying a thematic repertory established in earlier periods, the painters from the Bay of Kotor were gradually introducing new details and themes adopted from Western European Baroque art under indirect influences coming from the monastery of Hilandar, Corfu, Venice and Russia. This process makes this indigenous school of icon-painting, which spanned almost two centuries, comparable to the work of Serbian traditional religious painters (zografs and illuminators active north of the Sava and Danube rivers after the Great Migration of the Serbs (1690. Despite differences between the two, which resulted from different cultural and historical circumstances in which Serbs lived under Ottoman, Venetian and Habsburg rules, similarities in iconography and style, which were inspired by an urge to counteract proselytic pressures, are considerably more important.

2011-01-01

Although urinary 1,6-hexamethylene diamine (HDA) is a useful biomarker of exposure to 1,6-hexamethylene diisocyanate (HDI), a large degree of unexplained intra- and inter-individual variability exists between estimated HDI exposure and urine HDA levels. We investigated the effect of individual and workplace factors on urine HDA levels using quantitative dermal and inhalation exposure data derived from a survey of automotive spray painters exposed to HDI. Painters' dermal and breathing-zone HDI-exposures were monitored over an entire workday for up to three separate workdays, spaced approximately one month apart. One urine sample was collected before the start of work with HDI-containing paints, and multiple samples were collected throughout the workday. Using mixed effects multiple linear regression modeling, coverall use resulted in significantly lower HDA levels (p = 0.12), and weekday contributed to significant variability in HDA levels (p = 0.056). We also investigated differences in urine HDA levels stratified by dichotomous and classification covariates using analysis of variance. Use of coveralls (p = 0.05), respirator type worn (p = 0.06), smoker status (p = 0.12), paint-booth type (p = 0.02), and more than one painter at the shop (p = 0.10) were all found to significantly affect urine HDA levels adjusted for creatinine concentration. Coverall use remained significant (p = 0.10), even after adjusting for respirator type. These results indicate that the variation in urine HDA level is mainly due to workplace factors and that appropriate dermal and inhalation protection is required to prevent HDI exposure.

Una dialógica desestabilizadora del orden social y sexual: el médico argentino Juan Lazarte en la revista anarquista Estudios (1932-1936

Directory of Open Access Journals (Sweden)

Jiménez-Lucena, Isabel

2014-12-01

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.

Differential Absorption Measurements of Atmospheric Water Vapor with a Coherent Lidar at 2050.532 nm

Wind and water vapor are two major factors driving the Earth's atmospheric circulation, and direct measurement of these factors is needed for better understanding of basic atmospheric science, weather forecasting, and climate studies. Coherent lidar has proved to be a valuable tool for Doppler profiling of wind fields, and differential absorption lidar (DIAL) has shown its effectiveness in profiling water vapor. These two lidar techniques are generally considered distinctly different, but this paper explores an experimental combination of the Doppler and DIAL techniques for measuring both wind and water vapor with an eye-safe wavelength based on a solid-state laser material. Researchers have analyzed and demonstrated coherent DIAL water vapor measurements at 10 micrometers wavelength based on CO2 lasers. The hope of the research presented here is that the 2 gm wavelength in a holmium or thulium-based laser may offer smaller packaging and more rugged operation that the CO2-based approach. Researchers have extensively modeled 2 um coherent lasers for water vapor profiling, but no published demonstration is known. Studies have also been made, and results published on the Doppler portion, of a Nd:YAG-based coherent DIAL operating at 1.12 micrometers. Eye-safety of the 1.12 micrometer wavelength may be a concern, whereas the longer 2 micrometer and 10 micrometer systems allow a high level of eyesafety.

Alpha-particle doses to human organs and tissues from internally-deposited 226Ra and 228Ra

International Nuclear Information System (INIS)

Keane, A.T.; Schlenker, R.A.

1981-01-01

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

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 The aim of this text is to analise The Girls, book in which portuguese novelist Agustina Bessa-Luís concerns the compatriot painter Paula Rego's life and work. In spite of its biographic contours, with special focus on Rego's childhood and her relationship with Victor Willing, the text brings various reflexions about the nature of the artistic job itself. It is believed that, by reading the novel, it is possible to consider it not only as a critic appreciation report of Rego's artistic fortune, but also as a book which value indwells in itself. By introducing the painter's biography, Bessa-Luis finds connections with her own experience, and use them as starting points to weave a great number of metalinguistic reflexions, as well as thoughts about the relation between text and canvas. Considering that, it is intended to demonstrate how the book accuses an interartistical dialog, also demonstrating connecting points between Bessa-Luis writing and the images that permeates the novel.

PIXE analysis of Italian ink drawings of the XVI century

2005-01-01

The composition of inks in a group of 24 drawings of ten XVI century Italian painters, has been determined by PIXE at the external micro-beam line of the Centro de Micro Analisis de Materiales of the Universidad Autonoma de Madrid. Ink elemental thicknesses have been determined by comparison with a set of certified thin standards.

Full Text Available Seeking funds to finance the war against the Turks which it entered in July 1876, Serbia, ruled by Prince Milan Obrenović, passed the decision on issuing paper banknotes with no backing in precious metals. They were printed at the national printing house in Belgrade. About 1500 pieces of banknotes of the Main National Treasury of the Principality of Serbia were printed in different denominations: 1, 5, 10, 50, and 100 dinars. These banknotes were never actually in circulation, being the test prints only, used to check whether the machines and technology for their future printing were working properly. They are extremely rare and popular with collectors. The most interesting ones are the 1-dinar banknotes because they have no reverse side, the 5-dinar banknotes because they were painted by the poet and painter Đura Jakšić, and the 10-dinar ones because they feature the drawings of the painter Đorđe Krstić.

The composition of inks in a group of 24 drawings of ten XVI century Italian painters, has been determined by PIXE at the external micro-beam line of the Centro de Micro Análisis de Materiales of the Universidad Autónoma de Madrid. Ink elemental thicknesses have been determined by comparison with a set of certified thin standards. A comprehensive comparison of inks has also been performed by renormalisation of spectra and definition of an ink-to-ink distance. The elemental compositions and the ink-to-ink distances give consistent results that are generally in line with the appearance of the drawings and add relevant instrumental information to the stylistic observation, revealing for example the presence of retouches and additions in different parts of a drawing.

Full Text Available No presente artigo é apresentada a leitura singular da obra marxiana efetuada por Althusser, leitura que é radicalmente oposta à do marxismo humanista e/ou hegeliano. Em geral, defende-se que o conteúdo do conceito de sobredeterminação é o principal elemento que diferencia as dialéticas marxiana e hegeliana. De forma focada, passa-se de uma apresentação das noções de Mao Tsé-Tung sobre a contradição e a dialética às reflexões propriamente althusserianas sobre a sobredeterminação e a determinação em última instância pelo econômico. Em seguida discute-se as diferenças entre o sistema de esferas hegeliano e o edifício marxiano para concluir com um debate e uma negação da ideia de que a dialética marxista é uma inversão da de Hegel.

Cell phone use is considered as an essential part of everyday life saturating all age groups and demographics. This study aimed to explore the effect of various cell phone functions on postural control and mobility in the elderly. Twenty healthy older (mean age 72.5±2.9) and twenty young (26.3±2.8) adults participated in this study. Postural balance was assessed by measuring the center of pressure (CoP) displacement with (talking on a cell phone (CONVERSE), dialing a number (DIAL) and listening to music (MUSIC)) and without cell phone use. Mobility was assessed by the Timed Up and Go Test (TUGT). Results showed that for both groups, the CoP parameters increased significantly during the CONVERSE (pcell phone use impairs similarly standing postural balance of elderly and young adults. Interestingly, in the elderly, all cell phone functions used altered mobility with the dialing function causing the largest mobility deterioration. Copyright © 2017 Elsevier Inc.

New laser design for NIR lidar applications

Vogelmann, H.; Trickl, T.; Perfahl, M.; Biggel, S.

2018-04-01

Recently, we quantified the very high spatio-temporal short term variability of tropospheric water vapor in a three dimensional study [1]. From a technical point of view this also depicted the general requirement of short integration times for recording water-vapor profiles with lidar. For this purpose, the only suitable technique is the differential absorption lidar (DIAL) working in the near-infrared (NIR) spectral region. The laser emission of most water vapor DIAL systems is generated by Ti:sapphire or alexandrite lasers. The water vapor absorption band at 817 nm is predominated for the use of Ti:sapphire. We present a new concept of transversely pumping in a Ti:Sapphire amplification stage as well as a compact laser design for the generation of single mode NIR pulses with two different DIAL wavelengths inside a single resonator. This laser concept allows for high output power due to repetitions rates up to 100Hz or even more. It is, because of its compactness, also suitable for mobile applications.

Full Text Available Car painters who work near volatile organic compounds (VOCs sources, including paints, solvents and painting processes may be exposed to highly elevated VOCs levels. This study investigates air samples from car painting houses in Thailand to evaluate the health risks following inhalation exposure. Personal air samplings were obtained at nine garages in Phitsanulok, Thailand from June to September 2012. The concentrations of benzene, toluene, ethylbenzene, xylenes, and styrene in the air workplaces were significantly higher than in a control group of office workers (p < 0.05. Toluene, xylene and ethylbenzene were the most abundant species. However, all VOCs in these air samples were lower than TWA limit of Thailand and the OSHA standard. The lifetime cancer and non-cancer risks for the workers exposed to VOCs were also assessed. The average lifetime cancer risk was 41.0 (38.2-47.2 per million, which is in the acceptable risk. The average lifetime non-cancer risk, the HI, was 0.962 (0.643-1.397, which is well below the reference hazard level. Urine samples, collected after 8-h work periods which were analyzed for VOCs metabolites, including t,t muconic acid, hippuric acid, mandelic acid and m-hippuric acid, demonstrate that the average levels of metabolites in car painters and in controls were close. All VOCs metabolites in urine samples were lower than BEI of ACGIH standard. Blood samples, collected after 8-h work periods which were analyzed by single cell gel electrophoresis (comet assay. The DNA damage, assessed by tail moment, demonstrates that the average of tail moment in car painters were significantly higher than in the controls (p < 0.05.

Did poor eyesight influence Goya's late works? Medicine and art history in search for an interpretation of Goya's late paintings.

Pérez-Trullén, José M; Ascaso, Francisco J; Auría, María J

2018-04-15

The aim of this article is to 'determine' the scope of Goya's eyesight difficulties and assess the extent to which those difficulties might explain his style of painting in the last years of his life. We analyse the correspondence and late works of the Aragonese painter Francisco de Goya y Lucientes (1746-1828), who has been admired for his use of colour, his energetic loose brushstrokes, his disregard for details and his bold compositions, as well as for his different artistic styles throughout his life. The evolution of Goya's style of painting in his later works seems to have been the consequence of an eyesight condition, probably age-related cataracts at an advanced stage. The faded dark backgrounds, which become blurred with the silhouette of the person portrayed, could indicate a certain degree of eye strain. This can be traced in all these works, but is especially evident in the unfinished portrait of Pío de Molina (1827-1828), as well as in the portraits of Mariano Goya, the artist's grandson (1827), and Jacques Galos (1826). It has been considered that the late and isolated Goya's sight problems were a belated consequence of his severe illness of 1792. Nevertheless, in our opinion, this is a simplistic explanation and, given the painter's age, it is logical to presume that their cause could be age-related lens opacities. This article argues that medicine may become a subsidiary science to art history, as it can provide empirical evidence of the way painters' illnesses may have a strong impact on their artworks. © 2018 Acta Ophthalmologica Scandinavica Foundation.

The study of the materials and techniques employed for wall painting, complementing the information from historical and aesthetic data, contributes to the integrated knowledge of the iconographer and his period. In the 16th century, regarding the iconography in the former Byzantine area, besides the School of Crete and Francos Catelanos and his school, a third artistic personality who also created his own school, Onoufrios, appeared in central Albania and expanded his activity as a painter to northern Greece as well as nearby areas, such as Ohrid. Inscriptions documenting the works of Onoufrios are found in some of the churches that he decorated with wall paintings: “St. Apostles” (1547) Kastoria Greece, “St. Nicolas” Shelcan Albania, “St. Paraskevi” (1554), Valsh Albania, while are attributed to him the church of “St. Theodores” in Berati, Albania (before 1547) and others. He is one of the best icon painters of the whole Balkan region, and the best painter that has ever worked in Albanian territory. Onoufrios managed to combine the local painting tradition with the best tradition of the eastern (Paleologian) and western (Italian) schools, resulting in a realistic and natural depiction. He is the creator of the “Berati School” that expanded to other parts of the peninsula. His individual character can be distinguished in the work of his students: his son Nikolaos (who inherited his style in painting), Onoufrios from Cyprus, etc. Based on careful observations, we extracted number of paint samples from wall paintings of three of the above mentioned churches. Ground and paint layers were examined using micro-FTIR, Optical Microscopy, TXRF and SEM-EDS, to characterize materials and methods used by the artist to create these works. Our findings in each church are discussed and compared with the others in order to understand how and with what material and resources the painter worked and how he developed his technique.

2017-02-01

Full Text Available One of the noteworthy stories for the Iranian writers and painters is the story of Joseph and Zuleika. This story has elegantly been described many times in the poetry of Iranian famous poets and many painters have sought to illustrate this story. One of the themes of this story which has been considered in the present research is the party of Joseph and Zuleika in confronting with Egyptian women. Because the subject matter of this party has been Joseph’s beauty and it has been confirmed by a large number of people. Therefore, the painters have tried to picture the most beautiful human being by using all visual techniques. This research studies the aesthetics of the Joseph’s figure from Safavid School to the art of the contemporary era. With this assumption that in the Iranian painting, there has been a certain principle for painting the body and face of the most beautiful people; the present paper with the aim of finding the principles of men’s body and facial aesthetic has done the comparative study by concentration on the painting and designing of the body and face of Joseph in the figures. Some questions have been presented in this regard including whether it is possible to find an aesthetic approach common to all Iranian painting schools to show the most beautiful manly face and body? Whether exemplary beauty of Joseph is expressible by an indicator? What relation has the exemplary of Joseph had with the schools of Safavid art and the following schools? The method of this research is comparative and content analysis. The paper refers to the written and illustrated sources. The statistical society, including six ceremonies of painting and drawing, has been analyzed from Safavid school till the contemporary art; also, painter artists of this circle have been introduced. Matching the theoretical findings with the men’s most beautiful appearance manifested in the statue of majesty Joseph causes the acquisition of the embodied beauty

Full Text Available Gabriel del Barco was one of the most important tile painters working in Portugal during the transition from the 17^th to the 18^th centuries. This period is considered to be one of preparation preceding the great, emblematic era of Portuguese tile production during the 18^th century. Spanish born, Gabriel del Barco arrived in Lisbon when he was about twenty, and established himself there first as a painter of ceilings and later, as a tile painter. Articles on aspects of his life and work (relatively well-known, have been published, but they have provided only a fragmentary vision of this artist. Thus, this study unites numerous dispersed materials with the addition of heretofore-unknown documents concerning the painter. The author also offers a re-evaluation of the tiles painted by Barco by analyzing his signed tile panels, assisted by the use of new technologies.

Gabriel del Barco fue uno de los pintores de azulejos más significativos de cuantos trabajaron en Portugal a caballo de los siglos XVII y XVIII, momento en el que se estaba gestando una producción azulejera histórica para la caracterización de un arte que, con razón, ha sido identificado como uno de los más emblemáticos del patrimonio artístico portugués. Español de nacimiento, Gabriel del Barco llegó a Lisboa con casi veinte años. Se estableció en la ciudad, primero como pintor de techos y, más tarde, de azulejos. Su vida y obra, relativamente bien conocidas, han sido objeto de interés por parte de la historiografía portuguesa, que le ha dedicado algunos estudios, unos más enjundiosos que otros, pero, al cabo, todos ellos fragmentarios. El presente artículo pretende reunir las numerosas informaciones dispersas existentes sobre el pintor junto con datos desconocidos hasta nuestros días. Además de dar noticia de esa nueva documentación que ahora ve la luz, se procederá a hacer una reapreciación de la producción de Barco a

Effects of historical and predictive information on ability of transport pilot to predict an alert

Science.gov (United States)

Trujillo, Anna C.

1994-01-01

In the aviation community, the early detection of the development of a possible subsystem problem during a flight is potentially useful for increasing the safety of the flight. Commercial airlines are currently using twin-engine aircraft for extended transport operations over water, and the early detection of a possible problem might increase the flight crew's options for safely landing the aircraft. One method for decreasing the severity of a developing problem is to predict the behavior of the problem so that appropriate corrective actions can be taken. To investigate the pilots' ability to predict long-term events, a computer workstation experiment was conducted in which 18 airline pilots predicted the alert time (the time to an alert) using 3 different dial displays and 3 different parameter behavior complexity levels. The three dial displays were as follows: standard (resembling current aircraft round dial presentations); history (indicating the current value plus the value of the parameter 5 sec in the past); and predictive (indicating the current value plus the value of the parameter 5 sec into the future). The time profiles describing the behavior of the parameter consisted of constant rate-of-change profiles, decelerating profiles, and accelerating-then-decelerating profiles. Although the pilots indicated that they preferred the near term predictive dial, the objective data did not support its use. The objective data did show that the time profiles had the most significant effect on performance in estimating the time to an alert.

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.

To assess whether solvent use and workplace practices in the vehicle collision repair industry are associated with symptoms of neurotoxicity in spray painters and panel beaters (auto body repair workers). Neurobehavioural symptoms were assessed using a cross-sectional study design in 370 vehicle collision repair and 211 reference workers using the EUROQUEST questionnaire. Full-shift airborne solvent levels were measured in a subset (n=92) of collision repair workers. Solvent exposures were higher in spray painters than in panel beaters, but levels were below current international exposure standards. Collision repair workers were more likely to report symptoms of neurotoxicity than reference workers with ORs of 2.0, 2.4 and 6.4 (all p<0.05) for reporting ≥5, ≥10 and ≥15 symptoms respectively. This trend was generally strongest for panel beaters (ORs of 2.1, 3.3 and 8.2 for ≥5, ≥10 and ≥15 symptoms respectively). Associations with specific symptom domains showed increased risks for neurological (OR 4.2), psychosomatic (OR 3.2), mood (OR 2.1), memory (OR 2.9) and memory and concentration symptoms combined (OR 2.4; all p<0.05). Workers who had worked for 10-19 years or 20+ years in the collision repair industry reported consistently more symptoms than those who had only worked less than 10 years even after adjusting for age. However, those who worked more than 20 years generally reported fewer symptoms than those who worked 10-19 years, suggesting a possible healthy worker survivor bias. Despite low airborne solvent exposures, vehicle collision repair spray painters and panel beaters continue to be at risk of symptoms of neurotoxicity. Copyright © 2016 Elsevier B.V.

Diisocyanates, highly reactive monomers which cross-link polyurethane, are the most widely recognized causes of occupational asthma. Many exposed workers are end-users, including autobody spray painters who form a large population at risk. Neither the factors which determine incidence rate nor strategies for control have been adequately studied in this setting. We have conducted a cross-sectional survey of 23 (about one in five) autobody shops in the New Haven area to determine the feasibility of clinical epidemiological studies in this population. Among 102 workers, there was a high rate of airway symptoms consistent with occupational asthma (19.6%). Symptoms were most prevalent among those with the greatest opportunity for exposure (dedicated spray painters) and least among office workers; part-time painters had intermediate rates. Atopy was not associated with risk while smoking seemed to correlate with symptoms. Regular use of air-supplied respirators appeared to be associated with lower risk among workers who painted part- or full-time. We were unable to validate the questionnaire responses with peak expiratory flow record data attempted on a 1/3 sample of the workers. Despite intensive training and effort, subject compliance was limited. Among those who provided adequate data (24 of 38), only two demonstrated unequivocal evidence of labile airways; two others demonstrated lesser changes consistent with an occupational effect on flow rates. There was no clear association between these findings and either questionnaire responses or exposure classification. Overall, the survey suggests that there is a high prevalence of airway symptoms among workers in autobody shops, at least in part due to work-related asthma. However, there is need for both methodological and substantive research in this setting to document rates of occupational asthma and to develop a scientific basis for its effective control.

Gregório Lopes (c. 1490-1550) was one of the most prominent painters of the renaissance and Mannerism in Portugal. The painting "Mater Misericordiae" made for the Sesimbra Holy House of Mercy, circa 1535-1538, is one of the most significant works of the artist, and his only painting on this theme, being also one of the most significant Portuguese paintings of sixteenth century. The recent restoration provided the possibility to study materially the painting for the first time, with a multianalytical methodology incorporating portable energy-dispersive X-ray fluorescence spectroscopy, scanning electron microscopy-energy-dispersive spectroscopy, micro-X-ray diffraction, micro-Raman spectroscopy and high-performance liquid chromatography coupled to diode array and mass spectrometry detectors. The analytical study was complemented by infrared reflectography, allowing the study of the underdrawing technique and also by dendrochronology to confirm the date of the wooden panels (1535-1538). The results of this study were compared with previous ones on the painter's workshop, and significant differences and similitudes were found in the materials and techniques used.

Fray Juan Rizi en Italia

Full Text Available Since Tormo, Gusi and Lafuente wrote fray Juan Rizi's monograph in 1930, and Ángulo & Pérez Sánchez revised years later this study in their book Pintura madrileña del segundo tercio del siglo XVII, very little has been published about the life and work of the Benedictine painter. Furthermore, the Italian journey of Rizi, that involved the last 20 years of his life, has always been an enigma, resolved only in certain aspects, thanks to few news supplied by his biographers and the manuscripts the monk wrote during his staying in the Montecassino abbey. Our recent discovery of 8 new canvases painted by Rizi to decorate the Saints Cosme and Damian's chapel in the main church of Trevi nel Lazio (Frosinone, Italy, as well as the location of several new drawings in the Montecassino and Vatican libraries, will allow us to study his activity as painter in Italy and also to profile, with more accuracy, the history of the last years of his life.No disponible

The Brazil of Marianne North: Memories of an English Traveler

Ana Lúcia Almeida Gazzola

2008-09-01

Full Text Available Starting from reflections about woman and femininity in the Victorian era, the explosion of literary market in the 19th century, and the access of women to education, literature, and journalism, this text introduces the work of Marianne North, English painter who used to travel aiming to paint the flora of other countries, particularly the exotic tropical flora. Marianne became one of the most famous globetrotter travelers of her time, visiting several countries such as Canada, USA, Jamaica, Brazil, Tenerife, Japan, Borneo, Java, Ceylon, Singapore, India, Wales, Australia, New Zealand, Tasmania, South Africa, Seychelles Islands, and Chile. In total, she left registers of about 272 genres (almost 1000 species of plants, some of them little known by the experts. Hence, the text deals with the dual condition of Marianne North as a painter and author of reports about the visited countries. In Brazil, for instance, she lived between 1972 and 1873. Her professionalism and objectivity distinguish her from the other travelers of 19th century.

The painter is the first contemporary Russian artist to hold a solo exhibition in Turkey which took place in Tophane-i Amirane, the Gallery of Mimar Sinan University of Fine Arts, within the frame of cultural relations between Russia and Turkey. This article will touch upon the works of this exhibition as well as the other works of the artist being displayed in the gallery in Moscow which is named after him. ‘Apple’, his prominent work in this gallery, will be given special emphasis.

Painting or relief: The ideal icon in iconophile writing in Byzantium

Full Text Available This text is focused on the transformation of the definition of the icon in Byzantine image theory from an identification of graphe with painting in the writings of John of Damascus (ca. 675-754 to the equation of graphe with typos understood as the imprint of an intaglio on matter in the theory of Theodore Studies (759-826. The virtues of painting, therefore, are that its masters see their works admired and feel themselves to be almost like the Creator. Is it not true that painting is the mistress of all the arts or their principal ornament? If I am not mistaken, the architect took from the painter architrave's, capitals, bases, columns and pediments, and all other fine features of buildings. The stonemason, the sculptor, and all the workshops and crafts of artificers are guided by the rule and art of the painter. Indeed hardly any art, except the very meanest, can be found that does not somehow pertain to painting. So I would venture to assert that whatever beauty there is in things, it has been derived from painting.

Investigation of the gilding technique in two post-Byzantine wall paintings using micro-analytical techniques

2004-01-01

The main churches of two important monasteries in Thessalia, Central Greece, are decorated with wall paintings that hail from the post-Byzantine period. The mural decoration of the main church of the St. Byssarionas Monastery at Doussiko has been attributed to the iconographer Tzortzis. The same painter is believed to have also operated in the main church of the Transfiguration Monastery at the monastic community of Meteora. The light microscopic (LM) examination of the cross-sections of samples taken from the gilded areas of the wall paintings, together with the direct temperature resolved mass spectrometric (DTMS) and scanning electron microscopy-energy dispersive X-ray spectroscopic (SEM-EDX) analysis, revealed a further resemblance of the materials and the methodology employed. The gold leaf was applied to the paintings by means of a mordant, which contains linseed oil mixed with a lead-containing dryer and an earth pigment or clay. The present study can constitute additional evidence to reinforce the idea that the two churches may have been painted by the same painter or workshop

Self-Portrait of an Artist with a Book in her Hand

Directory of Open Access Journals (Sweden)

Alenka Spacal

2010-12-01

Full Text Available This article considers the book as an important emancipatory motif, expressing the tendency of women self-portrait painters to present themselves as educated and accomplished, and to establish their own subjectivity. In traditional self-portraits, since the Renaissance some female artists have presented themselves as autonomous active individuals depicted painting, reading, or playing a musical instrument. In the past, the motif of the reader has symbolized female erudition, education, and sophistication. In a time when women could only rarely attend school, the use of this motif represented an important and liberating gesture. In a period when artists preferred to portray women as nude seducers rather than as learned ladies, it was all the more important that some female artists endeavored to stress the role of women as readers. Although images of women authors with a book in their hands represented a symbol of learning and wisdom, this same motif could also be used to replace a female author’s signature. This is examined here with reference to the works of the Renaissance painter Sofonisba Anguissola.

5. The Basic Principles of The Working Process From Nature and the Role of Composition in Creating Landscape in Terms of Plein-Air

Savițkaia-Baraghin Iarîna

2017-03-01

Full Text Available Principles of possession of the landscape painting, applied by masters of the past, as well as theoretical elaborations of scientists in the field of chromatics, psychology and pedagogy of arts, become important components in improving training methods of artists in plein-air in contemporary conditions. The skills and knowledge gained in the process of pleinair studies form professional skills and improve the properties of painting and composition within the workshop. This studying outlines the stringency of training and development methods of creative individuality, especially in plein-air, where the principal teacher is the nature. The plein-air enriches color perception of the real world, located in the air, and mutual relationship of landscape with architecture and space determines knowledge of the issues of proportionality and subordination in compositions, educates sense of proportion and artistic taste. Improving visual mastery into the natural environment contributes to the formation to painters of the necessity to create outside the workshop, which is a necessary condition for the development of individuality and professional skills of the painter.

Measurement of fugitive emissions from gas processing plants in Alberta

Energy Technology Data Exchange (ETDEWEB)

Chambers, A. [Alberta Research Council, Edmonton, AB (Canada)

2004-07-01

This paper presents a new gas visualization camera created to detect leaks. An outline of the device's projected entry into the oil and gas industry was provided, and included: a demonstration of Differential Absorption Light Detection and Ranging (DIAL) and leak cameras to measure and reduce fugitive emissions; a comparison of DIAL measured emissions with estimated emissions; and a review of methods to measure particulate emissions. In addition, a background of gas leak visualisation technology was presented along with an an overview of DIAL and its results from sour gas plants. The results of a survey conducted in 2003 were presented, including leaks identified and repaired as well as a follow up leak survey. An analysis of pre and post-repair hydrocarbon emissions from the Deepcut area revealed a 60 per cent reduction with savings of $140,000 as well as additional savings from reduced carbon emissions. A similar survey conducted in another plant measured emissions from condensate tanks before and after cooler installation as well as from surrounding well sites, quantifying an 80 per cent reduction in methane emissions. Tasks identified for future research concerned particulate emissions and the development of Lidar methods which can currently identify particulates, but are not yet able to quantify them. Other tasks included a complete DIAL data workup and reporting; the quantification of both methane and carbon emissions reduction at a sour gas plant; a comparison of measured emissions with methods that estimate fugitives; and a complete review of particulate measurements. tabs, figs.
