Esmaeel, Yaqoub Y. R.

The educational system in Kuwait is undergoing some fundamental changes, and the need for reform of environmental education has become urgent as a result of the concerns of both the government and the public over environmental issues. It is in such a context that this research was conducted. The research was intended to develop, implement, and evaluate an experimental programme Man and Nutrition for Kuwaiti primary school pupils, aimed at developing a positive environmental achievement, Information about the present status of environmental concepts and environmental education in Kuwait was obtained from preliminary study such as interviews and curriculum analysis. Interviews were conducted in ten different primary schools in four districts in Kuwait, which involved 31 pupils in total, hi addition, information was obtained by analysis of the science curriculum for fourth grade primary schools. The preliminary study was carried out during the period April to October 1998. The results of the preliminary study served to aid the development of an experimental teaching programme. The experimental programme Man and Nutrition consisted of eight lessons printed in two booklets, a teacher's guide and pupil's textbook. The research included a review of the relevant literature examining the development of environmental programmes and activities in a number of countries, which were selected because of their environmental education approaches, and the variety of their environmental conditions. Pilot testing of the teaching programmes was carried out to ascertain the appropriateness of the materials and the data collecting instruments used for the evaluation of the main experimental study. The main study group included 115 pupils in four primary schools and four teachers selected in Kuwait. Data collecting included pre and post-tests and the course evaluation by teachers using semi-structured interviews. Statistical analysis of data obtained was carried out using the SPSS

Observations on the mechanism and location of ascites reabsorption in man

International Nuclear Information System (INIS)

Rector, W.G. Jr.; Ibarra, F.

1987-01-01

Animal data indicate that ascites is reabsorbed by a lymphatic mechanism and that these vessels are subdiaphragmatic in location. We evaluated the relative role of lymphatics in ascites reabsorption in man by comparing the ascites clearance and plasma appearance rates of intraperitoneally injected radiolabeled albumin to those of intraperitoneally injected labeled autologous red blood cells, which require, owing to their large size, lymphatic removal, in patients with cirrhosis and ascites. To evaluate the location of reabsorption, we repeated these measurements after replacing ascites in the subdiaphragmatic region with 500-1000 ml of intraperitoneally injected air, reasoning that this maneuver should slow or eliminate ascites reabsorption occurring at this site. We found that the transfer rates of albumin and red cells out of ascites were similar and that creation of pneumoperitoneum did not influence these rates. These data confirm that ascites protein reabsorption occurs via a lymphatic mechanism in man. They suggest, however, that these vessels may not be subdiaphragmatic in location

The work we present deals with the trust of man in a teleoperation system. Trust is important because it is linked to stress which modifies human reliability. We are trying to quantify trust. In this paper, we'll present the theory of trust in relationships, and its extension for a man-machine system. Then, we explain the links between trust and human reliability. Then, we introduce our experimental process and the first results concerning selfconfidence

IMP-8 observations of the spectra, composition, and variability of solar heavy ions at high energies relevant to manned space missions

Tylka, Allan J.; Dietrich, William F.

1999-01-01

In more than 25 years of almost continuous observations, the University of Chicago's Cosmic Ray Telescope (CRT) on IMP-8 has amassed a unique database on high-energy solar heavy ions of potential relevance to manned spaceflight. In the very largest particle events, IMP-8/CRT has even observed solar Fe ions above the Galactic cosmic ray background up to ∼800 MeV/nucleon, an energy sufficiently high to penetrate nearly 25 g/cm 2 of shielding. IMP-8/CRT observations show that high-energy heavy-ion spectra are often surprisingly hard power laws, without the exponential roll-offs suggested by stochastic acceleration fits to lower energy measurements alone. Also, in many solar particle events the Fe/O ratio grows with increasing energy, contrary to the notion that ions with higher mass-to-charge ratios should be less abundant at higher energies. Previous studies of radiation hazards for manned spaceflight have often assumed heavy-ion composition and steeply-falling energy spectra inconsistent with these observations. Conclusions based on such studies should therefore be re-assessed. The significant event-to-event variability observed in the high-energy solar heavy ions also has important implications for strategies in building probabilistic models of solar particle radiation hazards

During a Loss of Coolant Accident (LOCA) in Light Water Reactors (LWR), borated water is injected into the core through the safety injection system. The continuous vaporization of the water from the core may increase the concentration of boric acid in the core that, under certain conditions may reach the solubility limit and precipitate. This includes scenarios where the liquid water supply to the core is affected by possible blockages due to debris accumulation. Questions have been raised on the effects of the precipitate in the core on the flow behavior, including the possibility of additional blockages produced by precipitate accumulation. A simple experimental facility was constructed to perform experimental observations of the behavior of borated water under the combined effects of the boiling and the boric acid precipitation (BAP). The facility consists of a transparent polycarbonate vertical pipe where forty-five heated rods have been installed to supply the power to the water to reach the saturation temperature, and maintain a desired boil-off rate. The layout and geometry of the experimental apparatus were conceived to emulate a simplified core of a Pressurized Water Reactor (PWR). Experimental observations have been conducted under two different conditions. Preliminary tests were conducted to observe the behavior of the water and the boric acid precipitate during a boil-off scenario without borated water addition (decreasing water level). During the main test runs, borated water was constantly injected from the top of the test section to maintain a constant mixture level in the test section. Both tests assumed no flow from the bottom of the test section which may be the case of PWR LOCA scenarios in presence of debris-generated core blockage. The observations performed with a set of cameras installed around the test section showed interesting effects of the vapor bubbles on the boric acid precipitate migration and accumulation in the test section.

Pathways of evolution for man and machine

A simplified model of the future is introduced in order to examine the relations between man, machine, and extraterrestrial intelligence. The observed lack of extraterrestrials on earth is used as a boundary condition for the model. Two exobiological conclusions are obtained: (1) advanced extraterrestrials exist but are difficult to observe or to distinguish from natural phenomena, (2) lower level, man-like extraterrestrials, which are potentially observable, are rare in the Universe because they are rapidly replaced in the evolutinary sequence by the intelligent machines which they create. The decline of man is inferred and may take place as soon as 100 years from now or as long as 100,000 years from the present time. Thus, we are a short-lived species, having a life expectancy of only a million years. A note is appended on the rationale and methods of the search for extraterrestrial intelligence in light of the above calculations. The Tau Ceti and Epsilon Eridani systems present favourable opportunities for a radio-search experiment in 1987 and 1988, respectively.

Johannsen, G.

1987-01-01

The field of man-machine systems is introduced with its subareas and a short outline of its history of 45 years. Three current lines of development in university and industrial research are emphasized. Today, the human problem solving activities are experimentally investigated and analytically described more vigorously than the control activities. Further, improved information presentations and decision support are made possible through new technologies of computer graphics and expert systems. At last, work on a general design methodology for man-machine systems is in progress. The aim is to better support human operators of dynamic technological systems as well as designers of graphics for visual display units and of dialogue styles. Thereby, safety and availability of the complete system can be increased. (orig.) [de

Taylor, G.N.; Jee, W.S.S.; Mays, C.W.

The value of many toxicity studies, involving various experimental animals, is contingent on how reliably the data can be related to man. An equation has been proposed for extrapolating the Pu syndrome from dog studies to man. It employs the extensive human radium experience and a plutonium-radium toxicity ratio in the dog. The validity of this method is contingent on similar target tissues for both Pu and Ra and approximately equal RBE's for Pu relative to Ra in both man and the dog. Thus, although the radiosensitivity might be significantly different, the endpoints within a given tissue in man and the animal model must necessarily be comparative. The degree of parallelism in the radium-induced syndromes of man and the beagle are examined in order to assess the practicability of estimating Pu risk in man through use of a Pu-Ra toxicity ratio in the beagles

Experimental and computational investigation of adsorption performance of TC-5A and PSA-5A for manned spacecraft

Directory of Open Access Journals (Sweden)

Liu Meng

2015-12-01

Full Text Available Two kinds of molecular sieve materials, TC-5A and PSA-5A, were produced to satisfy with special requirement of manned space flight. Their CO2 adsorption performances were investigated and compared through two experiments, the thermo gravimetric analysis (TGA experiment and packed bed column experiment. Besides, some kinetic equations were compared according to the TGA experimental data, and their errors were analyzed. Finally, the classic linear driving force (LDF model is improved to the new Avrami’s model, and two models are analyzed based on the packed bed data. The TGA data shows that the CO2 loading has an approximately linear relationship with the CO2 concentration, and the best fit adsorption temperature range is from 283 to 303 K. The packed bed column results show that water vapor in air can affect the CO2 adsorption performance badly. The new Avrami’s model is proved more suitable to reflect the complex adsorption mechanism for two molecular sieves. The materials are proved having much better adsorption capacity than the other adsorbents with room temperature and low CO2 concentration (⩽1.0% in volume, and they can meet the aerospace requirements. This work will benefit the optimal design and simulation of the air revitalization (AR system for Chinese manned spacecraft.

Typhoon Man-Yi

2007-01-01

Typhoon Man-Yi was pummeling the Japanese island of Okinawa with winds between 230 and 295 kilometers per hour (125-160 knots, 144-184 miles per hour) and heavy rain on the morning of July 13, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured this image. The immense storm covered hundreds of kilometers with spiraling bands of thunderstorms, though it had lost the distinctive cloud-free eye it exhibited the day before. Typhoons are common in Japan, but powerful typhoons usually strike the island nation later in the year. The Japan Meteorological Agency said that Man-Yi is the fourth typhoon of the 2007 season and may be the most powerful ever observed in the northwest Pacific in July, reported Kyodo News. The Joint Typhoon Warning Center expected the typhoon to strike Kyushu, a southern Japanese island, on July 14, and then curve northeast along the eastern shore of Japan. By the time the storm reaches Tokyo on July 15, it should be degraded to a tropical storm. As of July 13, Typhoon Man-Yi had injured eight and flooded twenty houses in Okinawa, and forced airlines to cancel hundreds of flights, said Kyodo News. The storm was expected to bring heavy rain to Japan's Pacific coast. NASA image created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response team.

Full Text Available The paper analyzes a new for the Russian anthropology concept of the «working man», introduced in the Urals along with the propagation of a social and political movement «For the Working Man Protection»; the semantic content of the «man» and «labor» notions being observed as well as the process and problems of the working man formation in the modern world.The author emphasizes the asymmetry of the socio-economic and vocational educational infrastructure, along with the contradictions between the labor market demands for the technical and technological profile workers and the existing educational qualification structure of vocational schools.In author's opinion, the disorganization of labor training in comprehensive school and deficiencies of vocational education hinder the process of the industrial working man formation. The professional orientation system is criticized for being unable to meet the demands of modern economy and provide the young people with the adequate concept of the working career.For overcoming the above problems affecting the working man formation, the paper recommends modernization of the labor training system in comprehensive schools, reformation of vocational training, and renovation of professional orientation system. The special emphasis is given to the continuing training of the working man. 

Aerosol Optical Depths over Oceans: a View from MISR Retrievals and Collocated MAN and AERONET in Situ Observations

Witek, Marcin L.; Garay, Michael J.; Diner, David J.; Smirnov, Alexander

2013-01-01

In this study, aerosol optical depths over oceans are analyzed from satellite and surface perspectives. Multiangle Imaging SpectroRadiometer (MISR) aerosol retrievals are investigated and validated primarily against Maritime Aerosol Network (MAN) observations. Furthermore, AErosol RObotic NETwork (AERONET) data from 19 island and coastal sites is incorporated in this study. The 270 MISRMAN comparison points scattered across all oceans were identified. MISR on average overestimates aerosol optical depths (AODs) by 0.04 as compared to MAN; the correlation coefficient and root-mean-square error are 0.95 and 0.06, respectively. A new screening procedure based on retrieval region characterization is proposed, which is capable of substantially reducing MISR retrieval biases. Over 1000 additional MISRAERONET comparison points are added to the analysis to confirm the validity of the method. The bias reduction is effective within all AOD ranges. Setting a clear flag fraction threshold to 0.6 reduces the bias to below 0.02, which is close to a typical ground-based measurement uncertainty. Twelve years of MISR data are analyzed with the new screening procedure. The average over ocean AOD is reduced by 0.03, from 0.15 to 0.12. The largest AOD decrease is observed in high latitudes of both hemispheres, regions with climatologically high cloud cover. It is postulated that the screening procedure eliminates spurious retrieval errors associated with cloud contamination and cloud adjacency effects. The proposed filtering method can be used for validating aerosol and chemical transport models.

Man-made materials : An exciting area for hyperfine-interaction investigation

Freeman, A.; Wu, R.

1996-01-01

Man-made low-dimensional magnetic systems including surfaces, interfaces and multilayers, have attracted a great amount of attention in the past decade because, as expected, the lowered symmetry and coordination number offer a variety of opportunities for inducing new and exotic phenomena and so hold out the promise of new device applications. Local spin density functional (LSDF) ab initio electronic-structure calculations employing the full-potential -linearized augmented-plane-wave (FLAPW) method have played a key role in the development of this exciting field by not only providing a clearer understanding of the experimental observations but also predicting new systems with desired properties. One of the striking successes of theory in the last decade has been the calculation of hyperfine fields at surfaces and interfaces. Concurrently, several groups have followed the pioneering work of Korecki and Gradmann and have measured hyperfine fields at surfaces and interfaces. In this paper, it is reviewed new features of hyperfine-interaction investigations in man-made materials which are essential because the hyperfine field is not proportional to the magnetization and so interpretations of experiment are totally dependent on theory

A study has been made to obtain/collect sex specific data on human physical parameters of Bangladeshi population of 9 age groups covering all ages for establishing a Bangladeshi/Asian Reference Man for radiation protection purposes. Eleven physical parameters were considered for measurement, namely height and weight of the total body, sitting height, chest girth, combined height of head and neck, head circumference, head width, neck circumference, length of arm, circumference of arm and length of leg. Significant variation in values of respective parameters was observed in most cases between male and female populations of the same age group. The measured values were compared with those of ICRP Reference Man of Caucasian origin. It is observed that the values of physical parameters of Caucasian Reference Man are systematically and probably significantly higher than those of the corresponding Bangladeshi Reference Man. The weights of male and female population of Caucasian Reference Man are approximately 20-30% higher than those of the corresponding Bangladeshi man. Since the organs of the body are roughly proportional to the body weight, the respective masses of the organs would be different by the same ratio factor and could be used for internal dosimetry purposes.

The functions of man in space have been in a state of constant change since the first manned orbital flight. Initially, the onboard crewmen performed those tasks essential to piloting and navigating the spacecraft. The time devoted to these tasks has steadily decreased and the crewman's time is being allotted to functions other than orbital operations. The evolving functions include added orbital operational capabilities, experimentation, spacecraft maintenance, and fabrication of useful end items. The new functions will include routine utilization of the crewman to extend mission life, satellite retrieval and servicing, remote manipulator systems operations, and piloting of free-flying teleoperator systems. The most demanding tasks are anticipated to be associated with construction of large space structures. The projected changes will introduce innovative designs and revitalize the concepts for utilizing man in space.

Regarding human factors research on man-machine interface, a basic psychological experiment was conducted to observe psycho-physiological characteristics of on-line human cognitive behavior when cognitive tasks on learning and pattern classification were given to subjects by personal computer using a simple state transition model. During the experiment, three different types of subjects' data were recorded: (i) eye movement data by eye mark recorder, (ii) physio-electric signals by polygraph and (iii) verbal reports. Those subjects' data were analyzed with respect to: (i) the related human cognitive characteristics concerning problem solving strategy, measures of problem difficulty and mental image effect, (ii) observed eye movement characteristics such as saccade, attention, pupil reaction and blinking, etc., and (iii) obtained characteristics of skin potential response and heart rate. It was found that the application of psycho-physiological measurement would serve to objective and detailed analysis of on-line cognitive process. (author)

Pathways to man

Harley, J.H.

1980-01-01

The study of radionuclide pathways leading to man generally has the goal of allowing us to predict human exposure from measurements of the radionuclide concentration in some segment of the environment. This modelling process provides a valuable tool in both the regulatory and health protection fields. However, most of the models in the regulatory field and in the health physics profession were designed to maximize exposure estimates. It is preferable to have scientifically defensible estimates and to add suitable safety factors at the end. Thus we are still faced with the development and validation of suitable models for many of the radionuclides of interest. The most useful models will include means of assessing variability and uncertainty. In this case variability might be considered as the differences in behavior due to age, sex or other factors in animals or man and those differences among plant species or animal species that determine their uptake factors. The uncertainty, on the other hand, would be the estimate of possible error in the experimental measurements. Model parameters would always have some variability even for site-specific cases and broad averages for population groups would have to include a factor expressing the possible variabilty and uncertainity. Thus any exposure calculation would have to be expressed with some range and valid assessments of this range are required

Quantitative description of the physical, and metabolic parameters of the human body is the very basic for internal dosimetry. Compilation of anatomical and other types of data Asian populations for internal (and external) dosimetry is of grate significance because of the potential spread of nuclear energy use in the Asian region and the major contribution of the region to the world population (about 58%). It has been observed that some differences exist for habitat, race, body sizes and pattern of food consumption. In the early stage of revision of ICRP Reference man by the Task Group, Characteristics of the human body of non-European populations received considerable attention as well as those of the European populations of different sexes and ages. In this context, an IAEA-RCA Co-ordinated Research Program on Compilation of Anatomical, Physiological and Metabolic Characteristics for a Reference Asian Man endorsed. In later stages of reference Man revision, anatomical data for Asians was discusses together with those of European populations, presumably due to ICRP's decision of unanimous use of the Reference Man for radiation protection. Reference man models for adults and 15, 10, 5, 1, 0 year-old males and females of Asian populations were developed for use in internal and external dosimetry. Based on the concept of ICRP Reference Man (Publication 23), the reference values were derived from the normal organ mass data for Japanese and statistical data on the physique and nutrition of Japanese and Chinese. Also incorporated were variations in physical measurements, as observed in the above mentioned IAEA-RCA Co-ordinated Research Program. The work was partly carried out within the activities of the ICRP Task Group on Reference Man. The weight of the skeleton was adjusted following the revised values in Publication 70. This paper will report basic shared and non-shared characteristics of Reference Man' for Asians and ICRP Reference Man. (author)

Man-Made Object Extraction from Remote Sensing Imagery by Graph-Based Manifold Ranking

He, Y.; Wang, X.; Hu, X. Y.; Liu, S. H.

2018-04-01

The automatic extraction of man-made objects from remote sensing imagery is useful in many applications. This paper proposes an algorithm for extracting man-made objects automatically by integrating a graph model with the manifold ranking algorithm. Initially, we estimate a priori value of the man-made objects with the use of symmetric and contrast features. The graph model is established to represent the spatial relationships among pre-segmented superpixels, which are used as the graph nodes. Multiple characteristics, namely colour, texture and main direction, are used to compute the weights of the adjacent nodes. Manifold ranking effectively explores the relationships among all the nodes in the feature space as well as initial query assignment; thus, it is applied to generate a ranking map, which indicates the scores of the man-made objects. The man-made objects are then segmented on the basis of the ranking map. Two typical segmentation algorithms are compared with the proposed algorithm. Experimental results show that the proposed algorithm can extract man-made objects with high recognition rate and low omission rate.

This paper presents measured results of man-made noise in urban and suburban areas in the 2-GHz band with amplitude probability distribution (APD) in order to evaluate the impact of man-made noise on an experimental cryogenic receiver front-end (CRFE). The CRFE comprises a high-temperature superconducting filter, cryogenically-cooled low-noise amplifier, and highly reliable cryostat that is very compact. The CRFE is anticipated to be an effective way to achieve efficient frequency utilization and to improve the sensitivity of mobile base station receivers. It is important to measure the characteristics of the man-made noise in typical cellular base station antenna environments and confirm their impact on the CRFE reception with APD because if man-made noise has a stronger effect than thermal noise, the CRFE would fail to offer any improvement in sensitivity. The measured results suggest that the contribution of man-made noise in the 2-GHz band can be ignored as far as the wideband code division multiple access (W-CDMA) system is concerned.

In the poem "Always", the author Pablo Neruda employs the first person narration to incisively reveal the paradoxical traits in human nature by exploring man in relation to love. "I" play a role shifting from a calm narrator to a furious one, and the last recovering to a mild one, which offers a multiple visual angle to observe humanity. In sum, by means of continuous changes of my inner feelings in the poem, Pablo Neruda reveals the paradoxical humanity .

From the rights of man to the human rights: Man - nation - humanity

Full Text Available The insistence on the fact that human rights and the rights of man (codified in The Universal Declaration of Human Rights and Declaration of the Rights of Man and of the Citizen, respectively are not one and the same, which could be deduced from the notion of man common to both terms, is the key thesis of this text. By developing this motive, I try to determine the following: that the notion of man, by definition inclusive and abstractly non-discriminative term, is in fact established on tacit exclusions in the time of its inception (Enlightenment revolutinary era, and it was only upon these exclusions that the term man could have signified "the free and equal". Although the parallel or simultaneous evolution and implementation of the rights of man and national rights might seem contradictory, I seek to demonstrate that this paradox is only ostensible, arguing that the notion of man is itself limited and exclusionary, and is therefore compatible with the exclusivity which is the conditio sine qua non of nation. The consequences of nationalism - World Wars, primarily - proved that the conception of liberty and equality, based on the conception of fraternity of men (white European males, and of partial democracy pretending to be universal, cannot be maintained any further. Codification of universal human rights represents a reaction to this internal discrepancy inasmuch as it is a reaction to the destructiveness of all kinds of nationalisms. The notion of life, developed in this text, corresponds to the fundamental requirement for the right to life (as the first and the most basic of all human rights, which no longer belongs to "man", but to everyone.

Fragmented one dimensional man / El hombre unidimensional fragmentado

Full Text Available Paraphrase the title of the famous essay by Herbert Marcuse, since the image has traditionally been generated of man, masculinity, has been one-dimensional. I mean, the man was characterized by traits and behaviors established and entrenched since ancient time, considering all other distinguishing signs as mere deviations from the normative improper. But observe that this undeniable reality, as analyzed various researchers through what has come to be called Men's studies, has proven to be a fallacy difficult to maintain throughout history and today turns into fallacious and ineffective against changes in our current existing corporate models.

Full Text Available The aim of this study was to evaluate feed intake, digestibility, nitrogen balance, water balance, and performance of lambs fed diets containing old man saltbush hay associated with a concentrate. Thirty-two castrated feedlot Santa Inês lambs at approximately eight months of age, with 22 ± 1.97 kg body weight, were distributed into a completely randomized experimental design. Acid detergent fiber intake increased (P < 0.05, whereas non-fibrous carbohydrates intake decreased (P < 0.01. Inclusion of old man saltbush in the diet reduced (P < 0.01 the digestibility of dry and organic matter, neutral and acid detergent fiber, and non-fibrous carbohydrates. The intakes of digestible dry and organic matter, ether extract, total carbohydrates, and digestible non-fibrous carbohydrates also decreased (P < 0.01. Inclusion of old man saltbush did not influence water consumption from the trough by the sheep, averaging 4,327.20 mL/day?1. Body weight at slaughter and daily weight gain decreased linearly (P < 0.05 and feed conversion worsened as old man saltbush hay was added to the diet. Inclusion of old man saltbush at up to 40% replacing the concentrate in feedlot lamb diets does not compromise the performance of these animals.

To make real and accurate dose assessment method so far, it is necessitated to provide ''Reference Japanese Man'' based on anotomical, physiological and biochemical data of Japanese people instead of the Reference Man presented in ICRP Publications 23 and 30. This review describes present status of researched for the purpose of establishing of Reference Japanese Man. The Reference Japanese Man is defined as a male or female adult who lives in Japan with a Japanese life-style and food custom. His stature and body weight, and the other data was decided as mean values of male or female people of Japan. As for food custom, Japanese people take significantly smaller amount of meat and milk products than Western people, while larger intake amount of cereals and marine products such as fish or seaweeds. Weight of organs is a principal factor for internal dose assessment and mean values for living Japanese adult has been investigated and the value employable for dose assessment for organs and tissues are shown. To employ these values of Reference Japanese Man, it should be taken into account of age. Metabolic parameters should also be considered. Iodine metabolism in Japanese is quite different from that of Western people. The above-mentioned data are now tentatively employing in modification of table of MIRD method and others. (Takagi, S.)

2013-01-01

We investigated impedance perception characteristics of humans in the man-machine interface. Sensibility or operational feel about physical properties of machine dynamics is obtained through perception process. We evaluated the impedance perception characteristics of humans who are operating a mechanical system, based on extended Scheffe's subjective evaluation method in full consideration of the influence of impedance level, impedance difference, experiment order, individual difference and so on. Constant method based quantitative evaluation was adopted to investigate the influence of motion frequency and change of the impedance on human impedance perception characteristics. Experimental results indicate that humans perceive impedance of mechanical systems based on comparison process of the dynamical characteristics of the systems. The proposed method can be applied to quantify the design requirement of man-machine interface. The effectiveness of the proposed method is verified through experimental results.

[Knowledge of Man Returns: Some Considerations on Spirituality and Resilience].

Science.gov (United States)

Kumakura, Nobuhiro

2015-01-01

Over the last decade,"spirituality" and "resilience" have jointly become a topic in psychiatry. The aim of this paper is to discuss the future of psychiatry suggested by this topic. It may be related to what Jaspers, K. called "Knowledge of Man (die Erkenntnis des Menschen)". Knowledge of man in psychiatry can be learned only through clinical experince: e. g., clinical observations and case studies. Modern academic psychiatry seems to be suffering a loss of knowledge of man, which returns periodically in clinical practice. Hence, I will call the re-discovery of the topic in psychiatry as "Return of Man". Since WW II, there have been three eras in which psychiatrists showed deep concern regarding knowledge of man. Firstly, psychopathology and psychotherapy widely developed, when the destructive impulses of mankind were revealed in the nuclear weapons of WW II. Secondly, in the 1970's, the reforms of psychiatric services and legal systems took place somewhat successfully, when social reforms were concerns of the younger generations. Lastly, over the last decade, the topic again returned as spirituality and resilience, when scientists seemed to be powerless in the aftermath of the West Japan Earthquake. Regarding the definition of health made by the WHO in 1946, I further discuss that "Return of Man" in psychiatry is the necessary dynamism between negative and positive health, or between disease control and health promotion. There is an underlying dynamism between "Knowledge of Man" and natural sciences, which is constantly changing. So long as any theory can exist only as a part of dynamism, the Return of Man may re-surface whenever clinical theories do not fit with clinical realities.

gypsum has been predicted to precipitate in sea ice, it has never been observed. Here we provide the first report on gypsum precipitation in both experimental and natural sea ice. Crystals were identified by X-ray diffraction analysis. Based on their apparent distinguishing characteristics, the gypsum crystals were identified as being authigenic. The FREeZing CHEMistry (FREZCHEM) model results support our observations of both gypsum and ikaite precipitation at typical in situ sea ice temperatures and confirms the "Gitterman pathway" where gypsum is predicted to precipitate. The occurrence of authigenic gypsum in sea ice during its formation represents a new observation of precipitate formation and potential marine deposition in polar seas.

Objective: To investigate the specific activity of '2 4 Na per unit neutron fluence, A B/Φ ,in blood produced for Chinese reference man irradiated by 252 Cf neutron source,and to analyze the effects of scattering neutrons from ground,wall,and ceiling in irradiation site on it.Methods: A 252 Cf neutron source of 3×10 8 n/s and the anthropomorphic phantom were used for experiments. The phantom was made from 4 mm thick of outer covering by perspex and the liquid tissue-equivalent substitute in it. The data of phantom dimensions fit into Chinese reference man.The weight ratios of H, N, O and C in substitute equal from source to long axis of phantom were 1.1, 2.1, 3.1 and 4.1 m, respectively. Both the neutron source and the position of xiphisternum of the phantom were 1.6 m above the floor. Results: The average specific activity of 24 Na per unit neutron fluence was related to the irradiation-distances, d, and its maximum value, A B/ΦM , deduced by experimental data was about 1.85×10 -7 Bq·cm 2 ·g -1 . Conclusions: The A B/ΦM corresponds to that of phantom irradiated by plane-parallel beams, and the value is about more 3% than that by BOMAB phantom reported in literature. It has shown that floor-(wall-)scattered neutrons in irradiation site have significant contribution to the specific activity of 24 Na, but they contributed relatively little to the induced neutron doses. Consequently,using the specific activity of 24 Na for assessing accidental neutron doses received by an individual, the contribution of scattered neutrons in accident site will lead dose to be overestimated, and need to be correct.

1995-01-01

The nature and measurement methods of mental workload (MWL) for human cognitive activity at man-machine interface (MMI) were firstly discussed from the viewpoint of human information process model. Then, a model VDT experiment which simplifies the actual human-computer-interaction situation at MMI, was conducted for several subjects, where two subjects participated in experiment series and tried to solve the same cognitive task in competition. Adopted experimental parameters were (i)different kinds of cognitive task, and (ii)cycle time of information display, to see the influence on MWL characteristics from psycho-physiological viewpoint. A special processing unit for eye camera was developed and used for measuring subjects' eye movement characteristics. Concerning data analysis, total number of display presentation until problem solving (ie., total information needed for problem solving) was assumed as anchoring objective measure for MWL, and the investigations were conducted from two aspects; (i)global interpretation on MWL characteristics seen in the subjects' behavior from viewpoint of human information process model, and (ii)applicability of MWL by means of biocybernetic method. As regards to applicability of biocybernetic method, the nature of MWL characteristics was first divided into two aspects : (i)efficiency of visual information acquisition, and (ii)difficulty of inner cognitive process to solve problem, both in time pressure situation. Then, the data analysis results for eye movement characteristics were correlated to (i), while for heart rate characteristics, (ii). (author)

2014-06-01

The Window Design for Manned Spaceflight (WDMS) project was tasked with establishing the state-of-art and explore possible improvements to the current structural integrity verification and fracture control methodologies for manned spacecraft windows.A critical review of the state-of-art in spacecraft window design, materials and verification practice was conducted. Shortcomings of the methodology in terms of analysis, inspection and testing were identified. Schemes for improving verification practices and reducing conservatism whilst maintaining the required safety levels were then proposed.An experimental materials characterisation programme was defined and carried out with the support of the 'Glass and Façade Technology Research Group', at the University of Cambridge. Results of the sample testing campaign were analysed, post-processed and subsequently applied to the design of a breadboard window demonstrator.Two Fused Silica glass window panes were procured and subjected to dedicated analyses, inspection and testing comprising both qualification and acceptance programmes specifically tailored to the objectives of the activity.Finally, main outcomes have been compiled into a Structural Verification Guide for Pressurised Windows in manned spacecraft, incorporating best practices and lessons learned throughout this project.

Hecker, E.; Jung, E.G.; Marks, F.; Tilgen, W.

1993-01-01

This book presents an updated overview of the current state of the art in scientific, experimental and clinical investigations on the generation and the prevention of cancer of the skin. From the achievements presented, marked refinements in the assessment of the risk of cancer, by environmental and endogenous factors, including tumor virus, will be stimulated. They include the problem of the stratospheric 'ozone holes' above both poles of the earth causing much public concern as expressed by current headlines in the media and by the United Nations Environmental Program. Moreover, new ideas will merge for developing specific approaches to explore the mechanistic, i.e. ultimately the molecular-biological, causes of skin cancer and others. In addition, the experimental utilization of oncogens and of other techniques of molecular biology at all levels of the biology of tissues and cells, may open up entirely new facets in the research on skin cancer. Detailed knowledge of the mechanistic aspects of skin carcinogenesis may give important hints with respect to 'tailor-make' and utilize new anti-tumor agents in the therapy of skin cancer for the benefit of the cancer patient.

Advanced man-machine interaction. Fundamentals and implementation

Energy Technology Data Exchange (ETDEWEB)

Kraiss, K.F. (ed.) [Aachen Technische Hochschule (Germany). Lehrstuhl fuer Technische Informatik und Computerwissenschaften

2006-07-01

Man-machine interaction is the gateway providing access to functions and services, which, due to the ever increasing complexity of smart systems, threatens to become a bottleneck. This book therefore introduces not only advanced interfacing concepts, but also gives insight into the related theoretical background.This refers mainly to the realization of video-based multimodal interaction via gesture, mimics, and speech, but also to interacting with virtual object in virtual environments, cooperating with local or remote robots, and user assistance. While most publications in the field of human factors engineering focus on interface design, this book puts special emphasis on implementation aspects. To this end it is accompanied by software development environments for image processing, classification, and virtual environment implementation. In addition a test data base is included for gestures, head pose, facial expressions, full-body person recognition, and people tracking. These data are used for the examples throughout the book, but are also meant to encourage the reader to start experimentation on his own. Thus the book may serve as a self-contained introduction both for researchers and developers of man-machine interfaces. It may also be used for graduate-level university courses. (orig.)

Water retention behaviour of compacted bentonites: experimental observations and constitutive model

Directory of Open Access Journals (Sweden)

Dieudonne Anne-Catherine

2016-01-01

Full Text Available Bentonite-based materials are studied as potential barriers for the geological disposal of radioactive waste. In this context, the hydro-mechanical behaviour of the engineered barrier is first characterized by free swelling conditions followed by constant volume conditions. This paper presents an experimental study conducted in order to characterize the water retention behaviour of a compacted MX-80 bentonite/sand mixture. Then, based on observations of the material double structure and the water retention mechanisms in compacted bentonites, a new water retention model is proposed. The model considers adsorbed water in the microstructure and capillary water in the aggregate-porosity. The model is calibrated and validated against the experimental data. It is used for better understanding competing effects between volume change and water uptake observed during hydration under free swelling conditions.

A research programme was initiated in collaboration with IAEA/RCA to establish local sex specific data and latter on to contribute to define a reference Asian man/woman in the age ran-e of 5, 10, 15, 20-29, 30-39, 40-49 and 20-50 years in order to strengthen the radiation protection infrastructure of the country. Physical data on height, weight, chest and head circumference and food consumption data of reference Pakistani man/women were collected from various socioeconomic strata residing at different ecological areas of Pakistan. The present study revealed that our daily nutritional status and all the physical parameters are significantly lower than ICRP reference man of Caucasian origin except the standing height of male. Since the anatomical organs are roughly proportional to body size so approximation can be made for internal dosimetry purposes with the same ratio as defined by those countries who experimentally established their values.

Stratospheric ozone reduction and its relation to natural and man made sources

Energy Technology Data Exchange (ETDEWEB)

Isaksen, I S [Oslo Univ. (Norway). Dept. of Geophysics

1996-12-31

Approximately 90 % of the total ozone mass is in the stratosphere (between approximately 12 and 50 km), the rest is in the troposphere (below 12 km). The global distribution of ozone in the stratosphere and its variation over time have been studied extensively over several decades. These studies include observations by ground based instruments (e.g. Dobson instruments), instruments on airborne platforms (e.g. ozone sondes) and on satellites, and model studies which simulate the chemical and dynamical behaviour of the stratosphere. These studies have given good information about the processes which determine the ozone distribution, and how man made emissions affect the distribution. Observations have revealed that there are large year to year variations in stratospheric ozone above a particular location. These variations are difficult to predict as they are connected to irregular weather patterns. However, the observations have shown that there has been a long term decrease in stratospheric ozone on a global scale during the last two decades. The decrease has been most pronounced during the last five to six years and is seen both in the Northern and the Southern Hemispheres. The strong decrease in stratospheric ozone over the Antarctic continent, which has been observed since the mid 80s, and which has reduced the total ozone column with more than 50 % compared with earlier observations, is proven to be a result of increased man made emissions of CFCs. There are also mounting evidences that Northern Hemispheric ozone reductions observed since 1980 are connected to man made emissions of CFCs

These studies have given good information about the processes which determine the ozone distribution, and how man made emissions affect the distribution. Observations have revealed that there are large year to year variations in stratospheric ozone above a particular location. These variations are difficult to predict as they are connected to irregular weather patterns. However, the observations have shown that there has been a long term decrease in stratospheric ozone on a global scale during the last two decades. The decrease has been most pronounced during the last five to six years and is seen both in the Northern and the Southern Hemispheres. The strong decrease in stratospheric ozone over the Antarctic continent, which has been observed since the mid 80s, and which has reduced the total ozone column with more than 50 % compared with earlier observations, is proven to be a result of increased man made emissions of CFCs. There are also mounting evidences that Northern Hemispheric ozone reductions observed since 1980 are connected to man made emissions of CFCs

This study establishes an altiudinal gradient, spanning from the highland Andes (2400 m) to lowland Amazon, as a productive region for the study of bird pollination in Southeastern Peru. The 'Manú Gradient' has a rich history of ornithological research, the published data and resources from which lay the groundwork for analyses of plant-bird interactions. In this preliminary expedition we documented 44 plants exhibting aspects of the bird pollination syndrome, and made field observations of hummingbird visits at three sites spanning the Manú Gradient: 2800 m (Wayqecha), 1400 m (San Pedro), and 400 m (Pantiacolla). Some of the documented plant taxa are underrepresented in the bird pollination literature and could be promising avenues for future analyses of their pollination biology. The Manú Gradient is currently the focus of a concerted, international effort to describe and study the birds in the region; we propose that this region of Southeastern Peru is a productive and perhaps underestimated system to gain insight into the ecology and evolution of bird pollination. Observations were made on 11, 19, and 14 putatively bird pollinated plant species found at the high-, mid- and low-elevation sites along the gradient, respectively. Hummingbirds visited 18 of these plant species, with some plant species being visited by multiple hummingbird species or the same hummingbird species on differing occasions. Morphometric data is presented for putatively bird-pollinated plants, along with bill measurements from hummingbirds captured at each of three sites. Voucher specimens from this study are deposited in the herbaria of the Universidad Nacional de Agraria de La Molina (MOL), Peru and the University of British Columbia (UBC), Canada. The specimens collected represent a 'snapshot' of the diversity of bird-pollinated flora as observed over 10 day sampling windows (per site) during the breeding season for hummingbirds of Manú .

Observers for vehicle tyre/road forces estimation: experimental validation

Science.gov (United States)

Doumiati, M.; Victorino, A.; Lechner, D.; Baffet, G.; Charara, A.

2010-11-01

The motion of a vehicle is governed by the forces generated between the tyres and the road. Knowledge of these vehicle dynamic variables is important for vehicle control systems that aim to enhance vehicle stability and passenger safety. This study introduces a new estimation process for tyre/road forces. It presents many benefits over the existing state-of-art works, within the dynamic estimation framework. One of these major contributions consists of discussing in detail the vertical and lateral tyre forces at each tyre. The proposed method is based on the dynamic response of a vehicle instrumented with potentially integrated sensors. The estimation process is separated into two principal blocks. The role of the first block is to estimate vertical tyre forces, whereas in the second block two observers are proposed and compared for the estimation of lateral tyre/road forces. The different observers are based on a prediction/estimation Kalman filter. The performance of this concept is tested and compared with real experimental data using a laboratory car. Experimental results show that the proposed approach is a promising technique to provide accurate estimation. Thus, it can be considered as a practical low-cost solution for calculating vertical and lateral tyre/road forces.

Man-caused seismicity of Kuzbass

2010-05-01

A natural seismicity of Kuznetsk Basin is confined in the main to mountain frame of Kuznetsk hollow. In this paper materials of experimental work with local station networks within sediment basin are presented. Two types of seismicity display within Kuznetsk hollow have been understood: first, man-caused seismic processes, confined to mine working and concentrated on depths up to one and a half of km; secondly, seismic activations on depths of 2-56 km, not coordinated in plan with coal mines. Every of studied seismic activations consists of large quantity of earthquakes of small powers (Ms=1-3). From one to first tens of earthquakes were recorded in a day. The earthquakes near mine working shift in space along with mine working, and seismic process become stronger at the instant a coal-plough machine is operated, and slacken at the instant the preventive works are executed. The seismic processes near three lavas in Kuznetsk Basin have been studied in detail. Uplift is the most typical focal mechanism. Activated zone near mine working reach in diameter 1-1,5 km. Seismic activations not linked with mine working testify that the subsoil of Kuznetsk hollow remain in stress state in whole. The most probable causes of man-caused action on hollow are processes, coupled with change of physical state of rocks at loss of methane from large volume or change by mine working of rock watering in large volume. In this case condensed rocks, lost gas and water, can press out upwards, realizing the reverse fault mechanism of earthquakes. A combination of stress state of hollow with man-caused action at deep mining may account for incipient activations in Kuznetsk Basin. Today earthquakes happen mainly under mine workings, though damages of workings themselves do not happen, but intensive shaking on surface calls for intent study of so dangerous phenomena. In 2009 replicates of the experiment on research of seismic activations in area of before investigated lavas have been conducted

While the ``transport shortfall'' in the ``no-man's land'' has been observed often in delta-f codes, it has not yet been observed in the global total-f gyrokinetic particle code XGC1. Since understanding the interaction between the edge and core transport appears to be a critical element in the prediction for ITER performance, understanding the no-man's land issue is an important physics research topic. Simulation results using the Holland case will be presented and the physics causing the shortfall phenomenon will be discussed. Nonlinear nonlocal interaction of turbulence, secondary flows, and transport appears to be the key.

Whole body thermal model of man during hyperthermia

International Nuclear Information System (INIS)

Charny, C.K.; Hagmann, M.J.; Levin, R.L.

1987-01-01

A whole body thermal model of man has been developed to predict the changes in regional temperatures and blood flows during hyperthermia treatments with the miniannular phased array (MAPA) and annular phased array (APA) applicators. A model of the thermoregulatory response to regional heating based on the experimental and numerical studies of others has been incorporated into this study. Experimentally obtained energy deposition patterns within a human leg exposed to the MAPA were input into the model and the results were compared to those based upon a theoretical deposition pattern. Exposure of the abdomen to the APA was modeled with and without the aberrant energy deposition that has been described previously. Results of the model reveal that therapeutic heating (>42 0 C) of extremity soft tissue sarcomas is possible without significant systemic heating. Very high bone temperatures (>50 0 C) were obtained when the experimental absorption pattern was used. Calculations show that systemic heating due to APA exposure is reduced via evaporative spray cooling techniques coupled with high-velocity ambient air flow

[ManNAc, a new therapeutic agent to reduce Angptl4-induced proteinuria in MCD].

Science.gov (United States)

Clément, Lionel; Macé, Camille

2016-01-01

Current therapies used in minimal change disease (MCD) were originally designed to cure other diseases. They are only partially efficient, and present inconvenient side effects. Therefore, understanding the molecular mechanisms implicated in the pathogenesis of proteinuria in MCD could lead to new therapeutic strategies. A new experimental transgenic rat model of human MCD was generated. These NPHS2-Angptl4 transgenic rats over-express two different forms of the glycoprotein Angptl4 from the podocyte. The majority of the protein shows a lack of sialylation that is implicated in the pathogenesis of proteinuria. Supplementation of ManNAc, a precursor of sialic acid, significantly reduces albuminuria in those rats by increasing sialylation of the hyposialylated form of Angptl4. After treatment of the first episode of MCD with glucocorticoids in patients, ManNAc could be used as a maintenance drug, especially to reduce the frequency and intensity of relapse. ManNAc is a promising therapeutic agent for patients with MCD. © 2016 médecine/sciences – Inserm.

Air dehumidification by membrane with cold water for manned spacecraft environmental control

Directory of Open Access Journals (Sweden)

Shang Yonghong

2017-01-01

Full Text Available The traditional condensation dehumidification method requires additional gas-liquid separation and water recovery process in the manned spacecraft humidity control system, which would increase weight and complexity of systems. A new membrane dehumidification with cold water is proposed, which uses water vapor partial pressure difference to promote water vapor transmembrane mass transfer for dehumidification. The permeability of the membrane was measured and the experimental results agree well with the theoretical calculations. Based on the simulation of dehumidification process of cold water-membrane, the influence of module structure and working condition on dehumidification performance was analyzed, which provided reference for the design of membrane module construct. It can be seen from the simulation and experiments that the cold water-membrane dehumidification can effectively reduce the thermal load of the manned spacecraft.

A nematode in a subcutaneous nodule excised from the chest of a man in central California is described and identified as a third-stage larval dioctophymatid, probably Dioctophyma renale, though a Eustrongylides species could not be excluded. In all well-documented previously reported cases of D. renale infection in man, none of which was from North America, adult worms were discovered in the kidney at autopsy (5 cases), or were observed migrating or being expelled through the urethra (6 cases), discharged through the skin over an abscessed kidney (1 case), or detected by finding eggs in the urine (1 case).

Being less of a man or less of a woman: perceptions of chronic pain patients' gender identities.

Science.gov (United States)

Bernardes, Sónia F; Lima, Maria Luísa

2010-02-01

Living with chronic pain may be a threatening experience to one's own gender identity. Findings suggest that the presence of chronic pain does not allow individuals to achieve the most valued standards of being male or female in our societies. Such contention, however, has not yet been empirically supported. Therefore, our goal was to explore laypeople's and nurses' perceptions of the man/woman with chronic low-back pain (CLBP) as compared to the typical man/woman, respectively. Three hundred and sixteen laypeople (52.8% women) and 161 nurses (54% women) participated in this study. Half of the participants were presented with a written vignette depicting a man/woman with CLBP, followed by a list of 33 traits of the masculine and feminine stereotypes. Participants evaluated the extent to which each trait fit their image of the man/woman with CLBP. The other half of the participants described the image people in general had of the typical man/woman using the same list of traits. This study consisted on a quasi-experimental design, 2 (character's sex)x2 (type of character)x2 (participant's sex)x2 (health-care training). Results have generally supported our hypotheses. Both laypeople and nurses perceived: (1) the man with CLBP as having less masculinity and more femininity-related traits than the typical man; (2) the woman with CLBP as having less femininity and more masculinity-related traits than the typical woman; and (3) the man and woman with CLBP as more similar to each other than the typical man/woman. Issues on gender identity conflicts in CP patients are discussed.

A comprehensive study on rotation reversal in KSTAR: experimental observations and modelling

2017-12-01

Dedicated experiments have been performed in KSTAR Ohmic plasmas to investigate the detailed physics of the rotation reversal phenomena. Here we adapt the more general definition of rotation reversal, a large change of the intrinsic toroidal rotation gradient produced by minor changes in the control parameters (Camenen et al 2017 Plasma Phys. Control. Fusion 59 034001), which is commonly observed in KSTAR regardless of the operating conditions. The two main phenomenological features of the rotation reversal are the normalized toroidal rotation gradient ({{u}\\prime} ) change in the gradient region and the existence of an anchor point. For the KSTAR Ohmic plasma database including the experiment results up to the 2016 experimental campaign, both features were investigated. First, the observations show that the locations of the gradient and the anchor point region are dependent on {{q}95} . Second, a strong dependence of {{u}\\prime} on {νeff} is clearly observed in the gradient region, whereas the dependence on R/{{L}{{Ti}}} , R/{{L}{{Te}}} , and R/{{L}{{ne}}} is unclear considering the usual variation of the normalized gradient length in KSTAR. The experimental observations were compared against several theoretical models. The rotation reversal might not occur due to the transition of the dominant turbulence from the trapped electron mode to the ion temperature gradient mode or the neoclassical equilibrium effect in KSTAR. Instead, it seems that the profile shearing effects associated with a finite ballooning tilting well reproduce the experimental observations of both the gradient region and the anchor point; the difference seems to be related to the magnetic shear and the q value. Further analysis implies that the increase of {{u}\\prime} in the gradient region with the increase of the collisionality would occur when the reduction of the momentum diffusivity is comparatively larger than the reduction of the residual stress. It is supported by the perturbative

Birth and development of the man-made gemstones in the 20th century are outlined. Manufacturing gemstones was initiated by the invention of corundum production, followed by production of rubies and sapphires. In 1950 GE Co. synthesized diamonds, after that, most gemstones were manufactured consequently by progress of technologies of single crystal growing and ceramic manufacturing. In the 21st century, steep growth in demand is not expected but it seems to keep steady growth and the importance and necessity of man-made gemstones may be increased because of global environmental issues. Man-made gemstones seem to have both personality and variety of characteristics. (NEDO)

Effects of dose, species, and dosing vehicle on the disposition of methacrylonitrile (MAN) in male rats

International Nuclear Information System (INIS)

Sanchez, I.M.; Ghanayem, B.I.

1991-01-01

MAN is structurally similar to known carcinogen acrylontrile (AN), with nitriles having similar industrial uses. Current studies were designed to investigate the biological fate of 2- 14 C-MAN in rats. After gavage administration of 115, 11.5 or 1.15 mg MAN/kg in water, F344 male rats were placed in glass metabolism cages and urine, expired air and feces were collected. Rats were sacrificed at various times and concentration of MAN-derived radioactivity in tissues was determined. MAN was rapidly absorbed from the GI tract and distributed to all major tissues. Sixty-70% of the low and medium doses were exhaled as 14 CO 2 in 72 hr compared to 25% of the highest dose. While 40% of the highest dose was expired as organic volatiles in 72 hr, only 9-12% of the low and accounted for 20-30% of all doses within 72 hr after dosing. Comparison of MAN disposition in Sprague-Dawley (SD) and F344 rats at 115 mg/kg revealed that SD rats excreted a greater % of the dose as 14 CO 2 and in the urine than did F344 rats. Administration of 115 mg MAN/kg to SD male rats in safflower oil resulted in increased elimination of MAN-derived radioactivity as CO 2 , volatiles, and in the urine over that observed when administered in water. These results suggest that: (1) saturation of MAN metabolism occurs at high doses: (2) MAN metabolism and disposition differ with the strain of rats studied; (3) MAN disposition may vary with the dosing vehicle used; and (4) MAN metabolism and disposition is apparently different from that reported on AN

Chromosome phylogenies of man, great apes, and Old World monkeys.

Science.gov (United States)

De Grouchy, J

1987-08-31

The karyotypes of man and of the closely related Pongidae--chimpanzee, gorilla, and orangutan--differ by a small number of well known rearrangements, mainly pericentric inversions and one fusion which reduced the chromosome number from 48 in the Pongidae to 46 in man. Dutrillaux et al. (1973, 1975, 1979) reconstructed the chromosomal phylogeny of the entire primate order. More and more distantly related species were compared thus moving backward in evolution to the common ancestors of the Pongidae, of the Cercopithecoidae, the Catarrhini, the Platyrrhini, the Prosimians, and finally the common ancestor of all primates. Descending the pyramid it becomes possible to assign the rearrangements that occurred in each phylum, and the one that led to man in particular. The main conclusions are that this phylogeny is compatible with the occurrence during evolution of simple chromosome rearrangements--inversions, fusions, reciprocal translocation, acquisition or loss of heterochromatin--and that it is entirely consistent with the known primate phylogeny based on physical morphology and molecular evolution. If heterochromatin is not taken into account, man has in common with the other primates practically all of his chromosomal material as determined by chromosome banding. However, it is arranged differently, according to species, on account of chromosome rearrangements. This interpretation has been confirmed by comparative gene mapping, which established that the same chromosome segments, identified by banding, carry the same genes (Finaz et al., 1973; Human Gene Mapping 8, 1985). A remarkable observation made by Dutrillaux is that different primate phyla seem to have adopted different chromosome rearrangements in the course of evolution: inversions for the Pongidae, Robertsonian fusions for the lemurs, etc. This observation may raise many questions, among which is that of an organized evolution. Also, the breakpoints of chromosomal rearrangements observed during evolution

1999-01-01

Several interesting phenomena, such as the formation of a particular potential profile with a protuberance around the core and oscillatory stationary states termed electric pulsation, have been discovered using a heavy ion beam probe in the electron cyclotron heated plasmas of the CHS. This paper presents experimental observations which indicate that bifurcation of the radial electric field is responsible for such phenomena; existence of an ECH power threshold to obtain the profile with a protuberance, and its striking sensitivity to density. In particular, Flip-flop behavior of the potential near the power threshold clearly demonstrates bifurcation characteristics. Bifurcation of radial electric field in neoclassical theory is presented, and its qualitative expectation is discussed in the bifurcation phenomena. The neoclassical transition time scale between two bifurcative sates is compared with the experimental observations during the electric pulsation. It is confirmed that the neoclassical transition time is not contradictory with the experimental one. (author)

Symbolism in prehistoric man.

Science.gov (United States)

Facchini, F

2000-12-01

The aptitude for symbolization, characteristic of man, is revealed not only in artistic representations and funerary practices. It is exhibited by every manifestation of human activity or representation of natural phenomena that assumes or refers to a meaning. We can recognize functional symbolism (tool-making, habitative or food technology), social symbolism, (language and social communication) and spiritual symbolism (funerary practices and artistic expressions). On the basis of these concepts, research into symbolism in prehistoric man allows us to recognize forms of symbolism already in the manifestations of the most ancient humans, starting with Homo habilis (or rudolfensis). Toolmaking, social organization and organization of the territory are oriented toward survival and the life of the family group. They attest to symbolic behaviors and constitute symbolic systems by means of which man expresses himself, lives and transmits his symbolic world. The diverse forms of symbolism are discussed with reference to the different phases of prehistoric humanity.

The first major man-made environmental problem was the soil acidification, caused primarily by the massive industrial emissions of sulphur dioxide. Then came the problem of ozone depletion, caused by the emissions of man-made halocarbons. More recently, the possibility of man-made climate change has received a lot of attention. These three man-made problems are interconnected in fundamental ways and require for their solution interdisciplinary and international approach. Narrowing of the scientific uncertainties connected with the problems mentioned above can be expected through international `Global Change` programmes such as the World Climate Research Programme (WCRP) and the International Geosphere-Biosphere Programme (IGBP). Periodic assessments of the type produced by the IPCC will clearly be needed. Also in the future such assessments should form the scientific basis for international negotiations and conventions on the climate change issue

1976-01-01

The significance of human genetic pathology is stated and a study is made of the assumed effect of low level ionizing radiations. The theoretical notions thus derived are compared to experimental data which are poor. A quick survey of the literature shows that is has not yet been possible to establish a direct relationship between an increase of exposure and any genetic effect on man. However, this must not lead to conclude on the innoxiousness of radiation but rather shows how such analyses are difficult in as much as the effect investigated is necessarily low [fr

Multiscale Behavior of Viscous Fluids Dynamics: Experimental Observations

The dynamics of Newtonian fluids with viscosities of mafic to intermediate silicate melts (10-1000 Pa s) during slow decompression present multi-time scale processes. To observe these processes we have performed several experiments on silicon oil saturated with Argon gas for 72 hours, in a Plexiglas autoclave. The slow decompression, dropping from 10 MPa to ambient pressure, acting as the excitation mechanism, triggered several processes with their own distinct timescales. These processes generate complex non-stationary microseismic signals, which have been recorded with 7 high-dynamic piezoelectric sensors located along the conduit flanked by high-speed video recordings. The analysis in time and frequency of these time series and their correlation with the associated high-speed imaging enables the characterization of distinct phases and the extraction of the individual processes during the evolution of decompression of these viscous fluids. We have observed fluid-solid elastic interaction, degassing, fluid mass expansion and flow, bubble nucleation, growth, coalescence and collapse, foam building and vertical wagging. All these processes (in fine and coarse scales) are sequentially coupled in time, occur within specific pressure intervals, and exhibit a localized distribution along the conduit. Their coexistence and interactions constitute the stress field and driving forces that determine the dynamics of the conduit system. Our observations point to the great potential of this experimental approach in the understanding of volcanic conduit dynamics and volcanic seismicity.

Why Cannot Today’s Medicine Tolerate Man?

Directory of Open Access Journals (Sweden)

Farzad Goli

2017-08-01

Full Text Available Today, anyone who has travelled a little through history or reflected on social systems knows that although social systems are established and designed to satisfy our needs and demands, they have needs of their own which guarantee their life and may precede our needs. Hence, these systems, which were supposed to serve us indisputably like the genie, make us serve them in different ways. Medicine is one of such social systems which were undoubtedly established to satisfy our vital need to care and cure. To exist and develop, medicine needs to know and control personal and social conditions, and to actualize this need, it needs knowledge, money, and, perhaps prior to all of these, it needs to be trusted. To know man, he should be completely uncovered, observable, and dissected into his parts and the relationship between his parts should be explained in simple models. And to direct the condition toward maximum health, men should be converted into statistical entities and their individual differences, conditions, and narratives have to be ignored so that they become predictable and, consequently, controllable creatures. The story of relative, and almost necessary, conflict between man and medicine is as simple as it is explained. Before we go any further into the discussion, we should remember that a real man, with his whole phenomenological world and new-emergent and unique properties of autonomy and consciousness, may suddenly behave like a joker and disturb all the rules of medicine's play. It is natural that such subtleties cannot be tolerated by a materialistic model which is relying on knowledge of mechanistic organization of parts. The aim of this theoretical essay was to increase the readers’ awareness of biomedical model restrictions and organized cruelties it imposes on man in practice and theory. The discussion of alternate models which we are turning to recently has been undertaken in other essays.

2013-01-01

An ideal resource for lecturers, this book provides a comprehensive review of experimental space astronomy. The number of astronomers whose knowledge and interest is concentrated on interpreting observations has grown substantially in the past decades; yet, the number of scientists who are familiar with and capable of dealing with instrumentation has dwindled.  All of the authors of this work are leading and experienced experts and practitioners who have designed, built, tested, calibrated, launched and operated advanced observing equipment for space astronomy. This book also contains concise information on the history of the field, supported by appropriate references. Moreover, scientists working in other fields will be able to get a quick overview of the salient issues of observing photons in any one of the various energy, wavelength and frequency ranges accessible in space. This book was written with the intention to make it accessible to advanced undergraduate and graduate students.

Radioisotope diagnosis of pneumonia with the help of labelled microspheres of the blood serum albumin of man (experimental study)

The level of accumulation of albumin- 131 I microspheres in the lungs of intact animals reaches 90 per cent of the activity of the introduced preparation. In experimental pneumonia the inclusion of the preparation comprises 81.1+-6.23 per cent. The elimination of the labelled preparation from the lungs in experimental pneumonia occurs two times as slow than that in the control. The labelled microspheres of albumin make it possible to visualize the focus of inflammation, its spreading, conduct observations in dynamics. The peculiarities of accumulation and elimination from the lungs of the mentioned preparation make it possible with its help to differentiate pathological conditions of the lungs: inflammatory process, malignant neoformations and experimental embolism of the pulmonary artery

Nuclear fuel: the thinking man's alternative

International Nuclear Information System (INIS)

Chamberlain, N.

1989-01-01

'Nuclear Fuel ' The Thinking Man's Alternative' is the title of the 55th Melchett Lecture given by Neville Chamberlain, Chief Executive of British Nuclear Fuels plc. This article is based on the address, the essence of which is that the case for nuclear power should be based upon an appreciation of the totality and sophistication of man's handling of his energy needs - not on a glib catch-phase or on a simple political dogma or on an economic argument. Arguments in favour of nuclear power were discussed. The conclusion was that nuclear energy is the thinking man's alternative because only thinking man could have and can develop it; secondly, only thinking men should be authorized to exploit and control it; thirdly, a thinking person will appreciate that, properly thought out and controlled, it must be the most important source of future energy for the benefit of mankind.

Human capabilities in space. [man machine interaction

Science.gov (United States)

Nicogossian, A. E.

1984-01-01

Man's ability to live and perform useful work in space was demonstrated throughout the history of manned space flight. Current planning envisions a multi-functional space station. Man's unique abilities to respond to the unforeseen and to operate at a level of complexity exceeding any reasonable amount of previous planning distinguish him from present day machines. His limitations, however, include his inherent inability to survive without protection, his limited strength, and his propensity to make mistakes when performing repetitive and monotonous tasks. By contrast, an automated system does routine and delicate tasks, exerts force smoothly and precisely, stores, and recalls large amounts of data, and performs deductive reasoning while maintaining a relative insensitivity to the environment. The establishment of a permanent presence of man in space demands that man and machines be appropriately combined in spaceborne systems. To achieve this optimal combination, research is needed in such diverse fields as artificial intelligence, robotics, behavioral psychology, economics, and human factors engineering.

[Iron Man: Between Confusion of Identity and Addiction to Technology].

Science.gov (United States)

Chapellon, Sébastien; Houssier, Florian

The fascination surrounding a successful artwork is linked to the fact it faces the viewer to unknown aspects of his/her own psychic life. The same applies to the comics Iron Man. Behind the armour is hiding a man caught up in the traumatic incidences of life. The hero demonstrates a psychic weakness which, despite being deep, is, however, showing universal aspects.The analysis of his misfortunes reveals a narcissistic disorder. The article intends to set out the identity confusion the Marvel's protagonist is trapped in while highlighting the addictive troublesome linking him to his high-tech armour. This article also seeks to attest the fact the symbiosis between Tony Stark and Iron Man is anticipating the evolution of our behaviour with regard to new technologies.To this end, the authors are recalling the episodes of the series. Through the analysis of the confrontational dialogue the hero is maintaining with his iron armour, they explore how the internal experiment related to the sense of identity disorder is figured out. Thus, going through the key moments of the saga, the authors raise the ambiguity of his hero. The metapsychological analysis of the actions undertaken by Iron Man reflects a little-known facet of his personality, revealing a character more tormented than he really looks. However, the point is not to "treat" a fictional man, but to observe how he can help us to understand the internal behaviour of our patients, and also our own.The Faustian drama this comic leads to is hence understood as a living testimony of our own psychic conflicts. Furthermore, the analysis gives rise to a questioning as to the risk of identity confusion the technological progress can create at a time when the Human is more and more depending on the machines he creates himself.

Man-machine supervision

International Nuclear Information System (INIS)

Montmain, J.

2005-01-01

Today's complexity of systems where man is involved has led to the development of more and more sophisticated information processing systems where decision making has become more and more difficult. The operator task has moved from operation to supervision and the production tool has become indissociable from its numerical instrumentation and control system. The integration of more and more numerous and sophisticated control indicators in the control room does not necessary fulfill the expectations of the operation team. It is preferable to develop cooperative information systems which are real situation understanding aids. The stake is not the automation of operators' cognitive tasks but the supply of a reasoning help. One of the challenges of interactive information systems is the selection, organisation and dynamical display of information. The efficiency of the whole man-machine system depends on the communication interface efficiency. This article presents the principles and specificities of man-machine supervision systems: 1 - principle: operator's role in control room, operator and automation, monitoring and diagnosis, characteristics of useful models for supervision; 2 - qualitative reasoning: origin, trends, evolutions; 3 - causal reasoning: causality, causal graph representation, causal and diagnostic graph; 4 - multi-points of view reasoning: multi flow modeling method, Sagace method; 5 - approximate reasoning: the symbolic numerical interface, the multi-criteria decision; 6 - example of application: supervision in a spent-fuel reprocessing facility.

This volume contains the main papers presented at the 1997 EUROTOX Congress, Aaarhus, Denmark, 24-28 June 1997. Diversification in toxicology is not seen as splitting into subfields, but as the application of basic science to such diverse areas as man and his environment. The pressing issues which have been dealt with not only include reproductive effects of environmental chemicals (`xenoestrogens`), but also receptor-mediated toxic responses, new frontiers in human and ecological toxicology, chemoprevention of cancer and molecular approaches in toxicological research. The practical and ethical facets of toxicology, e.g. ecotoxicological risk assessment, biomarkers of exposure, complex chemical mixtures as well as animal welfare and the ethics of animal experimentation, are also treated.

The methodology of man-machine systems

International Nuclear Information System (INIS)

Hollnagel, E.

1981-10-01

This paper provides an elementary discussion of the problems of verification and validation in the context of the empirical evaluation of designs for man-machine systems. After a definition of the basic terms, a breakdown of the major parts of the process of evaluation is given, with the purpose of indicating where problems may occur. This is followed by a discussion of verification and validation, as two distinct concepts. Finally, some of the practical problems of ascertaining validity are discussed. The general conclusion is that rather than rely blindly on a well-established procedure or rule, one should pay attention to the meaningfulness of the aspects which are selected for observation, and the degree of systematism of the methods of observation and analysis. A qualitative approach is thus seen as complementary to a quantitative approach, rather than antithetical to it. (author)

Some consideration of Japanese standard man value

International Nuclear Information System (INIS)

Yoshizawa, Yasuo; Kusama, Tomoko

1976-01-01

Numerical values of standard man or reference man is important problem in the field of radiation protection and safety. The standard man values given by ICRP were obtained from European and North American adult data. For that reason, there are some theoretical problems in the application of standard man values to Japanese. The purpose of the present paper is to consider the difference of values between Japanese and standard man. The standard man values are divided into three categories. The first category is the size and weight of the body or organ, the second is the values of elementary composition, and the third is the numerical factors related to metabolic kinetics. It is natural that some values of the second and the third categories have little difference between Japanese and European. On the other hand, there are some differences in the value of the first category, but the differences can calculation in proportional allotment to the body weight. The values concerning the thyroid gland and iodine metabolism are important for radiation protection. It has been foreseen that these values of Japanese are significantly different from standard man. A survey of past reports was carried out with a view to search for normal values of the weight, iodine content, and iodine uptake rate of the thyroid of Japanese. The result of the survey showed that the weight of thyroid are about 19g for adult male and 17g for adult female and that the iodine contents are 12-22mg and iodine uptake rate (fw) is about 0.2.

Experimental observation of azimuthal shock waves on nonlinear acoustical vortices

International Nuclear Information System (INIS)

Brunet, Thomas; Thomas, Jean-Louis; Marchiano, Regis; Coulouvrat, Francois

2009-01-01

Thanks to a new focused array of piezoelectric transducers, experimental results are reported here to evidence helical acoustical shock waves resulting from the nonlinear propagation of acoustical vortices (AVs). These shock waves have a three-dimensional spiral shape, from which both the longitudinal and azimuthal components are studied. The inverse filter technique used to synthesize AVs allows various parameters to be varied, especially the topological charge which is the key parameter describing screw dislocations. Firstly, an analysis of the longitudinal modes in the frequency domain reveals a wide cascade of harmonics (up to the 60th order) leading to the formation of the shock waves. Then, an original measurement in the transverse plane exhibits azimuthal behaviour which has never been observed until now for acoustical shock waves. Finally, these new experimental results suggest interesting potential applications of nonlinear effects in terms of acoustics spanners in order to manipulate small objects.

Adaptation of the MapMan ontology to biotic stress responses: application in solanaceous species

Directory of Open Access Journals (Sweden)

Stitt Mark

2007-09-01

Full Text Available Abstract Background The results of transcriptome microarray analysis are usually presented as a list of differentially expressed genes. As these lists can be long, it is hard to interpret the desired experimental treatment effect on the physiology of analysed tissue, e.g. via selected metabolic or other pathways. For some organisms, gene ontologies and data visualization software have been implemented to overcome this problem, whereas for others, software adaptation is yet to be done. Results We present the classification of tentative potato contigs from the potato gene index (StGI available from Dana-Farber Cancer Institute (DFCI into the MapMan ontology to enable the application of the MapMan family of tools to potato microarrays. Special attention has been focused on mapping genes that could not be annotated based on similarity to Arabidopsis genes alone, thus possibly representing genes unique for potato. 97 such genes were classified into functional BINs (i.e. functional classes after manual annotation. A new pathway, focusing on biotic stress responses, has been added and can be used for all other organisms for which mappings have been done. The BIN representation on the potato 10 k cDNA microarray, in comparison with all putative potato gene sequences, has been tested. The functionality of the prepared potato mapping was validated with experimental data on plant response to viral infection. In total 43,408 unigenes were mapped into 35 corresponding BINs. Conclusion The potato mappings can be used to visualize up-to-date, publicly available, expressed sequence tags (ESTs and other sequences from GenBank, in combination with metabolic pathways. Further expert work on potato annotations will be needed with the ongoing EST and genome sequencing of potato. The current MapMan application for potato is directly applicable for analysis of data obtained on potato 10 k cDNA microarray by TIGR (The Institute for Genomic Research but can also be used

Reference Man for Asians as well as for Europeans-A change in the ICRP concept of Reference Man

International Nuclear Information System (INIS)

Tanaka, Gi-ichiro

1990-01-01

ICRP Reference Man, according to the definition, is primarily for Caucasoid populations (Western Europeans and North Americans) that contribute only 13 per cent of the world population. A speculative world population dose will, assuming a uniform exposure all over the world at a level of 10 μSv, be 50 k man Sv in total. Of this, all regions of Caucasoid populations may contribute by 22 per cent maximum. Asian populations will share about 58 per cent (29 k man Sv) of the world population dose. About eighty per cents in total of the world population can be convered by scientific dose assessment, if Reference Man data for Asians are made available. Thus the importance of establishing Asian Reference Man should be evident. The important point of characteristics of Asians is that they are 'Vegetarians' as compared to Westerners, which suggests different pathways with respect to transfer of radionuclides from foods to the human body. Therefore it is required to determine accurate and suitable parameters relevant to dose assessment. Considering the above, contribution of Japan in science and technology to Asian countries with 'knowhows' accumulated may be of a most urgent matter. (author)

Measurement of total body radioactivity in man

International Nuclear Information System (INIS)

Naversten, Y.

1982-01-01

Techniques for the determination of whole-body radioactivity in man using uncollimated NaI(Tl) detectors have been studied. Geometrical effects and photon attenuation effects due to the different shapes of humans as well as due to varying in-vivo radioactivity distributions have been evaluated particularly for scanning-bed geometries and the chair geometry. Theoretically it is shown that the attenuation effects are generally dominating, for full-energy-peak pulse-range methods. For the application in radiation protection a cheap and simple chair-geometry unit has been constructed and used at various places distantly from the home-laboratory, for studies of body activity of Cs-137 in northern Sweden. High body activities were found particularly in reindeer-breeding Lapps. The elimination rate of Cs-137 in man was studied in the stationary whole-body counter in Lund as well as with the field-system. For the study of the performances at low and high photon energies clinical applications of methods for gastro-intestinal absorption of vitamin B12 (Co-57; 122 keV) and total body potassium determination (K-40; 1.46 MeV, K-42; 1.52 MeV) have been evaluated. Theoretical and experimental results as well as experiences of applications in radiation protection and medicine show that the scanning-bed geometry effectively evens out redistributional effects. For optimum results, however, scatter-energy pulse-ranges rather than full-energy-peak ranges should be used. (Auth.)

Experimental Observation and Theoretical Description of Multisoliton Fission in Shallow Water

We observe the dispersive breaking of cosine-type long waves [Phys. Rev. Lett. 15, 240 (1965)] in shallow water, characterizing the highly nonlinear "multisoliton" fission over variable conditions. We provide new insight into the interpretation of the results by analyzing the data in terms of the periodic inverse scattering transform for the Korteweg-de Vries equation. In a wide range of dispersion and nonlinearity, the data compare favorably with our analytical estimate, based on a rigorous WKB approach, of the number of emerging solitons. We are also able to observe experimentally the universal Fermi-Pasta-Ulam recurrence in the regime of moderately weak dispersion.

By employing the dissociation energy and the equilibrium bond length for a diatomic molecule as explicit parameters, we generate an improved form of the Williams-Poulios potential energy model. It is found that the negative Williams-Poulios potential model is equivalent to the Manning-Rosen potential model for diatomic molecules. We observe that the Manning-Rosen potential is superior to the Morse potential in reproducing the interaction potential energy curves for the {{a}3 Σu+} state of the 6Li2 molecule and the {{X}1 sum+} state of the SiF+ molecule.

The study aimed to understand the context of resilient man when ill with prostate cancer. This is an ethnographic case study conducted with two prostate cancer survival men with a high degree of resilience. The data was collected on their places, in 2012 April and May, using semi-structured in-depth interviews, participant observation and ecomap. For the data analysis, it was built two units of meaning: "Identity of the resilient man: contextualizing the informants" and "The resilient man finding himself ill". It was noticed that the identity of being a resilient man, to these informants, was marked by historical and cultural difference which permeated their actions in the process of being ill with prostate cancer. It is important that nurses pay attention to the cultural aspects of human health, so that they can feel part of the healing process, becoming an active subject facing their own health.

Density response to central electron heating: theoretical investigations and experimental observations in ASDEX Upgrade

Science.gov (United States)

Angioni, C.; Peeters, A. G.; Garbet, X.; Manini, A.; Ryter, F.; ASDEX Upgrade Team

2004-08-01

Theory of ion temperature gradient (ITG) and trapped electron modes (TEMs) is applied to the study of particle transport in experimental conditions with central electron heating. It is shown that in the unstable domain of TEMs, the electron thermodiffusive flux is directed outwards. By means of such a flux, a mechanism is identified likely to account for density flattening with central electron heating. Theoretical predictions are compared with experimental observations in ASDEX Upgrade. A parameter domain (including L- and H-mode plasmas) is identified, in which flattening with central electron heating is observed in the experiments. In general, this domain turns out to be the same domain in which the dominant plasma instability is a TEM. On the contrary, the dominant instability is an ITG in plasmas whose density profile is not affected significantly by central electron heating. The flattening predicted by quasi-linear theory for low density L-mode plasmas is too small compared to the experimental observations. At very high density, even when the dominant instability is an ITG, electron heating can provide density flattening, via the coupling with the ion heat channel. In these conditions the anomalous diffusivity increases in response to the increased ion heat flux, while the large collisionality makes the anomalous pinch small and the Ware pinch important.

A methodology for costing man-rem

International Nuclear Information System (INIS)

Bieber, C.

1976-03-01

An attempt is made to provide a methodology for costing man-rem in a way that can be applied to station conditions, based on 1974 Pickering G.S. data. Factors taken into account were social costs, exposure costs (dose accounting, training, dosimetry) temporary labour costs, and permanent replacement labour costs. A figure of $620/ man-rem was derived. (LL)

First experimental observation of double-photon Compton scattering using single gamma detector

International Nuclear Information System (INIS)

Sandhu, B.S.; Saddi, M.B.; Singh, B.; Ghumman, B.S.

2003-01-01

Full text: The phenomenon of double-photon Compton scattering has been successfully observed using single gamma detector, a technique avoiding the use of complicated slow-fast coincidence set-up used till now for observing this higher order process. Here doubly differentiated collision cross-section integrated over direction of one of the two final photons, the direction of other one being kept fixed, has been measured experimentally for 0.662 MeV incident gamma photons. The energy spectra of the detected photons are observed as a long tail to the single-photon Compton line on the lower side of the full energy peak in the recorded scattered energy spectrum. The present results are in agreement with theory of this process

On the search for experimentally observed grain boundary phase transitions

International Nuclear Information System (INIS)

Balluffi, R.W.; Hsieh, T.E.

1987-07-01

The phase space for a heterogeneous system containing a grain boundary involves a relatively large number of variables (i.e., at least six plus the number of components), and it is therefore conceptually possible to induce a large variety of grain boundary phase transitions by selectively varying these parameters. Despite this, a review of the literature reveals that there have been virtually no clear-cut experimental observations of transitions reported in which the boundary structure has been observed as a function of time under well defined conditions. In current work, we are searching for roughening/faceting transitions and melting transitions for boundaries in Al by hot stage transmission electron microscopy. A clear example of a reversible roughening/faceting transition has been found. No evidence for melting has been found for temperatures as high as 0.96 T/sub m/ (by monitoring GBD core delocalization in several special boundaries with Σ ≤ 13) or 0.999 T/sub m/ (by observing the local diffraction contrast at general boundaries in polycrystalline specimens)

1. The effect of calcitonin, a large amount of calcium given orally, pentagastrin and glucagon on plasma 47Ca radioactivity curves in subjects pretreated with 47Ca was examined. 2. A sudden increase of plasma radioactivity after intravenous administration of calcitonin and pentagastrin and after the oral calcium load was observed in normal subjects; the intravenous infusion of glucagon was less effective. 3. Two thyroparathyroidectomized patients who responded to the calcitonin infusion did not respond to the oral calcium load. 4. These data may be considered to offer indirect evidence of endogenous calcitonin secretion in man.

BurnMan: A lower mantle mineral physics toolkit

KAUST Repository

Cottaar, Sanne; Heister, Timo; Rose, Ian; Unterborn, Cayman

2014-01-01

We present BurnMan, an open-source mineral physics toolbox to determine elastic properties for specified compositions in the lower mantle by solving an Equation of State (EoS). The toolbox, written in Python, can be used to evaluate seismic velocities of new mineral physics data or geodynamic models, and as the forward model in inversions for mantle composition. The user can define the composition from a list of minerals provided for the lower mantle or easily include their own. BurnMan provides choices in methodology, both for the EoS and for the multiphase averaging scheme. The results can be visually or quantitatively compared to observed seismic models. Example user scripts show how to go through these steps. This paper includes several examples realized with BurnMan: First, we benchmark the computations to check for correctness. Second, we exemplify two pitfalls in EoS modeling: using a different EoS than the one used to derive the mineral physical parameters or using an incorrect averaging scheme. Both pitfalls have led to incorrect conclusions on lower mantle composition and temperature in the literature. We further illustrate that fitting elastic velocities separately or jointly leads to different Mg/Si ratios for the lower mantle. However, we find that, within mineral physical uncertainties, a pyrolitic composition can match PREM very well. Finally, we find that uncertainties on specific input parameters result in a considerable amount of variation in both magnitude and gradient of the seismic velocities. © 2014.

Study on seismic stability of seawall in man-made island. Pt. 2. Experimental study of seismic performance of seawall using a centrifuge

International Nuclear Information System (INIS)

Kawai, Tadashi; Kanatani, Mamoru; Tochigi, Hitoshi; Tanaka, Yukihisa

1999-01-01

In the development of the man-made island siting technology of nuclear power plants, one of the most important factors to be verified in design is the seismic performance of the seawalls bounding the island. The overall stability of the seawalls, expected residual deformations of the caisson and of the armored embankment are important factors that must be evaluated. For this purpose, a detailed experimental study examining the performance of a seawall with an armored embankment has been conducted using centrifuge testing method. The effects of existence of an armored embankment, substratum density, substratum thickness, and the extent of ground improvement beneath the structure on the residual deformations of the seawall were closely examined. From the experiment results, it is indicated that displacements of a seawall placed on a thin and dense seabed are small and that the density of the seabed directly beneath the crushed stone mound on which the caisson is placed mainly influences the caisson movements. Moreover it is indicated that the residual displacements of the prototype expected from the results of these tests were small enough to preserve the functions of the seawall in protecting an island against ocean waves overtopping.

Man-made tiles frequently used in Japan were collected, and activity concentrations and radon ((222)Rn) exhalation rates in these tiles were measured. Dose estimations for inhabitants living in houses built using these tiles were also carried out. The activity concentrations of (226)Ra, (228)Ra and (40)K in the man-made tiles were 31-170, 35-110 and 260-980 Bq kg(-1), respectively. The (222)Rn exhalation rates in the tiles were 8.8-21 μBq m(-2) s(-1). The ranges of experimental activity concentrations and (222)Rn exhalation rates were almost identical to those of natural rocks used as typical building materials in Japan. The maximum value of effective dose to inhabitants living in houses built with the man-made tiles was 0.14 mSv y(-1), which is lower than the reference level range (1-20 mSv y(-1)) for abnormally high levels of natural background radiation published in the ICRP Publication 103. © The Author 2015.

Emblem for the third manned Skylab mission - Skylab 4

Science.gov (United States)

1973-01-01

This is the emblem for the third manned Skylab mission. It will be a mission of up to 56 days. The symbols in the patch refer to the three major areas of investigation proposed in the mission. The tree represents man's natural environment and relates directly to the Skylab mission objectives of advancing the study of Earth resources. The hydrogen atom, as the basic building block of the universe, represents man's exploration of the physical world, his application of knowledge, and his development of technology. Since the Sun is composed primarily of hydrogen, it is appropriate that the symbol refers to the solar physics mission objectives. The human silhouette represents mankind and the human capacity to direct technology with a wisdom tempered by regard for his natural environment. It also directly relates to the Skylab medical studies of man himself. The rainbow, adopted from the Biblical story of the flood, symbolizes the promise that is offered man. It embraces man and extends to t

Physiotherapists promote physical activity as part of their practice. This study reviewed the behaviour change techniques physiotherapists use when promoting physical activity in experimental and observational studies. Systematic review of experimental and observational studies. Twelve databases were searched using terms related to physiotherapy and physical activity. We included experimental studies evaluating the efficacy of physiotherapist-led physical activity interventions delivered to adults in clinic-based private practice and outpatient settings to individuals with, or at risk of, non-communicable diseases. Observational studies reporting the techniques physiotherapists use when promoting physical activity were also included. The behaviour change techniques used in all studies were identified using the Behaviour Change Technique Taxonomy. The behaviour change techniques appearing in efficacious and inefficacious experimental interventions were compared using a narrative approach. Twelve studies (nine experimental and three observational) were retained from the initial search yield of 4141. Risk of bias ranged from low to high. Physiotherapists used seven behaviour change techniques in the observational studies, compared to 30 behaviour change techniques in the experimental studies. Social support (unspecified) was the most frequently identified behaviour change technique across both settings. Efficacious experimental interventions used more behaviour change techniques (n=29) and functioned in more ways (n=6) than did inefficacious experimental interventions (behaviour change techniques=10 and functions=1). Physiotherapists use a small number of behaviour change techniques. Less behaviour change techniques were identified in observational studies compared to experimental studies, suggesting physiotherapists use less BCTs clinically than experimentally.

The initial data gathered on measurements of total body weight and weights of specific organs from autopsy cases of normal Filipinos are reported. Comparison of the above data with the Reference Man data of ICRP which was based primarily on Caucasians suggests some differences in the average weight and height of whole body and in the weights of some organs. Hence there appears to be a need for the establishment of Filipino standard man which can be used in the estimation of internal dose commitment of the Filipinos. (author)

Experimental observation of fluid echoes in a non-neutral plasma

International Nuclear Information System (INIS)

Yu, Jonathan H.; Driscoll, C. Fred

2002-01-01

Experimental observation of a nonlinear fluid echo is presented which demonstrates the reversible nature of spatial Landau damping, and that non-neutral plasmas behave as nearly ideal 2D fluids. These experiments are performed on UCSD's CamV Penning-Malmberg trap with magnetized electron plasmas. An initial m i =2 diocotron wave is excited, and the received wall signal damps away in about 5 wave periods. The density perturbation filaments are observed to wrap up as the wave is spatially Landau damped. An m t =4 'tickler' wave is then excited, and this wave also Landau damps. The echo consists of a spontaneous appearance of a third m e =2 wave after the responses to the first two waves have inviscidly damped away. The appearance time of the echo agrees with theory, and data suggests the echo is destroyed at least partly due to saturation

Annular tautomerism: experimental observations and quantum mechanics calculations

Cruz-Cabeza, Aurora J.; Schreyer, Adrian; Pitt, William R.

2010-06-01

The use of MP2 level quantum mechanical (QM) calculations on isolated heteroaromatic ring systems for the prediction of the tautomeric propensities of whole molecules in a crystalline environment was examined. A Polarisable Continuum Model was used in the calculations to account for environment effects on the tautomeric relative stabilities. The calculated relative energies of tautomers were compared to relative abundances within the Cambridge Structural Database (CSD) and the Protein Data Bank (PDB). The work was focussed on 84 annular tautomeric forms of 34 common ring systems. Good agreement was found between the calculations and the experimental data even if the quantity of these data was limited in many cases. The QM results were compared to those produced by much faster semiempirical calculations. In a search for other sources of the useful experimental data, the relative numbers of known compounds in which prototropic positions were often substituted by heavy atoms were also analysed. A scheme which groups all annular tautomeric transformations into 10 classes was developed. The scheme was designed to encompass a comprehensive set of known and theoretically possible tautomeric ring systems generated as part of a previous study. General trends across analogous ring systems were detected as a result. The calculations and statistics collected on crystallographic data as well as the general trends observed should be useful for the better modelling of annular tautomerism in the applications such as computer-aided drug design, small molecule crystal structure prediction, the naming of compounds and the interpretation of protein—small molecule crystal structures.

This report consolidates research carried out at Clemson University and Stanford University where a series of measurements were undertaken to identify the man-made radiation present in four bands used by rather different services, namely, L1 Band (1563.42 1587.42 MHz), the Unified S-Band (2025 2110 MHz), the 2.4 GHz Industrial, Scientific and Medical (ISM) Band (2400 2482.50 MHz), and the 23.6-24.0 GHz Passive Sensing Band. Results show that there were distinctive differences in the measurement data in the frequency bands, which should be expected based on the function/regulation associated with each. The GPS L1 Band had little to none terrestrial man-made sources, but the ISM 2.4 GHz Band had a large number of man-made sources regardless of the site and the time. The Unified S Band showed mixed results depending on the sites. The Passive Sensing Band does not contain appreciable man-made radiation.

2012-01-01

In this report for an Accreditation to Supervise Research (HDR), the author proposes an overview of his research works. These works first addressed quantitative spectroscopy and more particularly the measurement of absolute absorption coefficients which are necessary parameters for the quantification of molecules which are remotely sensed through their spectroscopic signature. Secondly, the author addresses the adjustment of line lists in the infrared for a better investigation of recent observations of Titan's atmosphere made by the Cassini mission. Thirdly, he reports the use of this line list for the processing of observations of Titan. The last part addresses an experimental atmospheric simulation which aims at reproducing Titan's atmosphere by submitting its main components (nitrogen and methane) to an energetic flow representative of what is present on Titan

2011-07-01

Full Text Available In this paper we present the design of a sliding mode controller for attitude control of spacecraft actuated by three orthogonal reaction wheels. The equilibrium of the closed loop system is proved to be asymptotically stable in the sense of Lyapunov. Due to cases where spacecraft do not have angular velocity measurements, an estimator for the generalized velocity is derived and asymptotic stability is proven for the observer. The approach is tested on an experimental platform with a sphere shaped Autonomous Underwater Vehicle SATellite: AUVSAT, developed at the Norwegian University of Science and Technology.

A methodological approach for a comparative assessment of ionising radiation effects on man and non-human species, based on the use of Radiation Impact Factor (RIF) - ratios of actual exposure doses to biota species and man to critical dose is described. As such doses, radiation safety standards limiting radiation exposure of man and doses at which radiobiological effects in non-human species were not observed after the Chernobyl accident, were employed. For the study area within the 30 km ChNPP zone dose burdens to 10 reference biota groups and the population (with and without evacuation) and the corresponding RIFs were calculated. It has been found that in 1986 (early period after the accident) the emergency radiation standards for man do not guarantee adequate protection of the environment, some species of which could be affected more than man. In 1991 RIFs for man were considerably (by factor of 20.0-1.1 x 10 5 ) higher compared with those for selected non-human species. Thus, for the long term after the accident radiation safety standards for man are shown to ensure radiation safety for biota as well

RevManHAL: towards automatic text generation in systematic reviews.

Science.gov (United States)

Torres Torres, Mercedes; Adams, Clive E

2017-02-09

Systematic reviews are a key part of healthcare evaluation. They involve important painstaking but repetitive work. A major producer of systematic reviews, the Cochrane Collaboration, employs Review Manager (RevMan) programme-a software which assists reviewers and produces XML-structured files. This paper describes an add-on programme (RevManHAL) which helps auto-generate the abstract, results and discussion sections of RevMan-generated reviews in multiple languages. The paper also describes future developments for RevManHAL. RevManHAL was created in Java using NetBeans by a programmer working full time for 2 months. The resulting open-source programme uses editable phrase banks to envelop text/numbers from within the prepared RevMan file in formatted readable text of a chosen language. In this way, considerable parts of the review's 'abstract', 'results' and 'discussion' sections are created and a phrase added to 'acknowledgements'. RevManHAL's output needs to be checked by reviewers, but already, from our experience within the Cochrane Schizophrenia Group (200 maintained reviews, 900 reviewers), RevManHAL has saved much time which is better employed thinking about the meaning of the data rather than restating them. Many more functions will become possible as review writing becomes increasingly automated.

CaveMan Enterprise version 1.0 Software Validation and Verification.

Energy Technology Data Exchange (ETDEWEB)

Hart, David

2014-10-01

The U.S. Department of Energy Strategic Petroleum Reserve stores crude oil in caverns solution-mined in salt domes along the Gulf Coast of Louisiana and Texas. The CaveMan software program has been used since the late 1990s as one tool to analyze pressure mea- surements monitored at each cavern. The purpose of this monitoring is to catch potential cavern integrity issues as soon as possible. The CaveMan software was written in Microsoft Visual Basic, and embedded in a Microsoft Excel workbook; this method of running the CaveMan software is no longer sustainable. As such, a new version called CaveMan Enter- prise has been developed. CaveMan Enterprise version 1.0 does not have any changes to the CaveMan numerical models. CaveMan Enterprise represents, instead, a change from desktop-managed work- books to an enterprise framework, moving data management into coordinated databases and porting the numerical modeling codes into the Python programming language. This document provides a report of the code validation and verification testing.

Alternative Frameworks for the Study of Man.

Markova, Ivana

1979-01-01

Two frameworks for the study of man are discussed. The Cartesian model views man as a physical object. A dialectic framework, with the emphasis on the self, grew out of nineteenth century romanticism and reflects the theories of Hegel. Both models have had an effect on social psychology and the study of interpersonal communication. (BH)

[Christian responsibility and experimental medicine. Experiments with and on humans, experiments on animals].

Science.gov (United States)

Grosse, Heinrich W

2002-01-01

The Jewish-Christian convictions that man was created as the image of God founded the "ethics of unavailability" which contrast with the utilitarian "ethics of interests." As man s nature is imperfect according to biblical understanding, those responsible in the field of experimental medicine should counteract all tendencies in society which promote an utopian definition of health and an eugenic mentality (idea of the "perfection of mankind"). Consequently, scientists must reflect their own image of man and the effects of their actions on this image. The goals of experimental medicine must also be examined under the aspect of fairness: do they only benefit a minority in the rich industrial nations? As in research on humans, the ethical evaluation of animal experiments must consider the question of the underlying image of humanity and the responsibility of mankind connected to it. Because of changes in society's values, the validity of traditional anthropocentrism is increasingly questioned. However, this does not affect the view of the special position of man as the bearer of responsibility. Even though there are different biblical statements on the relationship between man and animal, the Christian maxim to minimise violence towards animals can be derived from them. In the case of animal experiments this means: experiments which cause the animals severe suffering must be avoided by waiving the potential gain of knowledge from them. In general: in an ethical discussion on medical experiments using humans or animals, the public must be informed completely and involved effectively. A moratorium must be possible before plans become facts. Thinking about ethical problems in the area of experimental medicine should not be separated from the far-reaching questions about changes in our lifestyle and consumer behaviour.

The con man as model organism: the methodological roots of Erving Goffman's dramaturgical self.

Science.gov (United States)

Pettit, Michael

2011-01-01

This article offers a historical analysis of the relationship between the practice of participant-observation among American sociologists and Erving Goffman's dramaturgical model of the self. He was a social scientist who privileged ethnography in the field over the laboratory experiment, the survey questionnaire, or the mental test. His goal was a natural history of communication among humans. Rather than rely upon standardizing technologies for measurement, Goffman tried to obtain accurate recordings of human behavior through secretive observations. During the 1950s, he conducted three major studies as a participant-observer, disguised from those studied through insincere performances. As originally presented, his dramaturgical theory did not draw upon the theater as the governing metaphor, but rather the confidence game. It is suggested that Goffman's writings exemplify what Gerd Gigerenzer calls the tools-to-theories heuristic. Goffman's depiction of the confidence man's behavior closely mirrored how he and his fellow sociologists described the practice of participant-observation. Both were represented as embedded and attentive yet coolly detached observers skilled at playing different roles as the situation necessitated. The similarities between his own professional behavior and the activities of the confidence man may have suggested to Goffman the latter as a model for human nature.

Man and technology in the future

International Nuclear Information System (INIS)

1993-01-01

The Royal Swedish Academy of Engineering Sciences has set up a committee known as The Committee of Man, Technology and Society. The members of this committee form an interdisciplinary group for the study of the interaction between scientific and technological advances and the way in which society evolves. Most of the committees activities have focused on the present relationship between man, technology and society. Attempts have been made to assess the future influence on society of key developments in biotechnology, electronic communication and systems analysis. In order to pursue this path still further, the committee decided to arrange an international symposium on the topic Man and Technology in the Future at the village of Forsmark on the Baltic coast of Sweden. The proceedings consists of 13 lectures centered on energy systems - and the connected waste problems, biotechnology, and telecommunications. Separate abstracts were prepared for 5 of the lectures in this volume

1994-01-01

It is necessary to improve human reliability in order to gain a higher reliability of the total plant system taking an account of development of plant automation and improvement of machine reliability. Therefore, the role of the man-machine system will come to be important. Accordingly, the evaluation of the man-machine system design information is desired in order to solve the mismatch problem between plant information presented by the man-machine system and information required by the operator comprehensively. This paper discusses required functions and software framework for the man-machine interface design evaluation system. The man-machine interface design evaluation system has features to extract the potential matters which are inherent on the design information of man-machine system by simulating the operator behavior, the plant system and the man-machine system, considering the operator's cognitive performance and time dependency.

Hills, B.G.; Boettcher, D.B.; Reed, R.

1992-01-01

Sizewell B is the latest nuclear power station to be constructed in the United Kingdom: its Man-Machine Interfaces are therefore, by definition, the state-of-the-art. This paper discusses the principal Man-Machine Interfaces used in the operation of the station, and the systems that implement them. The Man-Machine Interface facilities discussed are: in the Main Control Room, which is used for normal operation and shutdown of the plant: in the Auxiliary Shutdown Room, which allows shutdown of the reactor if evacuation of the main Control Room is necessary: and in the Technical Support Centre, which is used for remote monitoring of the plant. The Man-Machine Interfaces that are described are parts of a station-wide group of interlinked computer systems called the Data Processing and Control System. This system collects data from the plant and displays it to the operators via discrete devices and on graphical computer displays. It also acquires control inputs from the operators via switches, which are then used to provide remote manual control, modulating control and sequence control. The computer system that handles the plant process data and alarm information displays uses a windowing interface with keyboard and trackerball navigation to allow easy retrieval and viewing of information. It is this system that is the main topic of this paper. (author)

Koch, J.A.; MacGowan, B.J.; Da Silva, L.B.; Matthews, D.L.; Mrowka, S.; Underwood, J.H.; Batson, P.J.

1992-01-01

We discuss our recent measurements of the spectral width of the 206.38 Angstrom x-ray laser transition in Ne-like Se. These measurements used a high-resolution grating spectrometer and were performed over a wide range of laser amplifier lengths. The data have enabled us to extrapolate the intrinsic line width and to observe the effects of gain-narrowing and saturation on the line profile. We find an intrinsic width which is 1.4 times the Doppler width, we observe gain-narrowing in intermediate length amplifiers, and we observe no re-broadening in long, saturated amplifiers. These results suggest that collisional line-broadening has a significant effect on the line profile and saturation behavior of this laser. We discuss modeling we have performed in order to simulate the experimental data, and we discuss future experimental and theoretical efforts we believe are necessary in order to understand line broadening and line transfer issues in x-ray laser plasmas

Indoor air pollution produced by man (carbon dioxide, odors)

Energy Technology Data Exchange (ETDEWEB)

Wanner, H U

1982-01-01

Man contributes to indoor air pollution by the release of heat, humidity, carbon dioxide, particles, micro-organisms and body odours. The rise in temperature and the concentrations of the different pollutants depend on the number of persons in a room, the utilization of the room and the activities of the persons. Current parameters for the evaluation of man-made pollution in indoor air are carbon monoxide and odours. Experiments have been carried out in a test chamber under controlled conditions in order to determine the relations between carbon monoxide and odours, since these are two current parameters for the evaluation of man-made pollution in indoor air. In these experiments the variables were the number of persons in the room, the activity of the persons and the ventilation rate. For the measurement of odours a special method has been developed in which the undiluted air is tested by a test panel and compared with air containing two different pyridine concentrations. A significant relationship has been observed between the odour intensity and the carbon dioxide content of the air, and the correlation did not depend on the number of persons and the ventilation rate. At ventilation rates of 12 to 15 m3 per person and hour the carbon dioxide concentration was below 0.15% and the odour intensity was characterized as being only little annoying. Higher ventilation rates are necessary during physical activity and in rooms with tobacco smoke. The minimum ventilation rates as deduced from the laboratory experiments are compared to known standards.

1986-12-01

A framework for Man-Machine System design in process industry projects is reported. It is based in the Guidelines for the Design of Man-Machine interfaces which have been generated in cooperation within the European Workshop for Industrial Computer Systems (EWICS). The application of EWICS Guidelines in industrial projects is demonstrated by six User Scenarios, which represent typical projects from different industries, e.g. electrical power generation and distribution, water control, pulp and paper production, oil and gas production. In all these projects Man-Machine System design has been conducted. It is recommended in the report that each Company develops its set of Man-Machine Systems Standard techniques/procedures. At present there are several techniques/procedures available which, for moderate costs, can be adapted to specific Company conditions. A menu of such Man-Machine System techniques/procedures is presented. Means of estimating the costs and benefits of Man-Machine System design are also described. (author)

Control of the Mirror Fusion Test Facility (MFTF) begins with the US Congress, which controls the dollars, which control the people, who control the nine top-level minicomputers, which control the 65 microprocessors, which control the hardware that controls the physics experiment. There are many interesting boundaries across which control must pass, and the one that this paper addresses is the man-machine one. For the MFTF, the man-machine interface consists of a system of seven control consoles, each allowing one operator to communicate with one minicomputer. These consoles are arranged in a hierarchical manner, and both hardware and software were designed in a top-down fashion. This paper describes the requirements and the design of the console system as a whole, as well as the design and operation of the hardware and software of each console, and examines the possible form of a future man-machine interface

The paper depicts a software assessment system, Dynamic Interaction Analysis Support (DIAS), based on computer simulation technology for man-machine interfaces (MMI) of a control room. It employs a computer to simulate the operation procedures of operations on man-machine interfaces in a control room, provides quantified assessment, and at the same time carries out analysis on operational error rate of operators by means of techniques for human error rate prediction. The problems of placing man-machine interfaces in a control room and of arranging instruments can be detected from simulation results. DIAS system can provide good technical supports to the design and improvement of man-machine interfaces of the main control room of a nuclear power plant

A Rich Man, Poor Man Story of S-Adenosylmethionine and Cobalamin Revisited.

Science.gov (United States)

Bridwell-Rabb, Jennifer; Grell, Tsehai A J; Drennan, Catherine L

2018-06-20

S-adenosylmethionine (AdoMet) has been referred to as both "a poor man's adenosylcobalamin (AdoCbl)" and "a rich man's AdoCbl," but today, with the ever-increasing number of functions attributed to each cofactor, both appear equally rich and surprising. The recent characterization of an organometallic species in an AdoMet radical enzyme suggests that the line that differentiates them in nature will be constantly challenged. Here, we compare and contrast AdoMet and cobalamin (Cbl) and consider why Cbl-dependent AdoMet radical enzymes require two cofactors that are so similar in their reactivity. We further carry out structural comparisons employing the recently determined crystal structure of oxetanocin-A biosynthetic enzyme OxsB, the first three-dimensional structural data on a Cbl-dependent AdoMet radical enzyme. We find that the structural motifs responsible for housing the AdoMet radical machinery are largely conserved, whereas the motifs responsible for binding additional cofactors are much more varied.

Experimental observation of triple correlations in fluids

M.Ya. Sushko

2013-03-01

Full Text Available We present arguments for the hypothesis that under some conditions, triple correlations of density fluctuations in fluids can be detected experimentally by the method of molecular spectroscopy. These correlations manifest themselves in the form of so-called 1.5-(or sesquialteral scattering. The latter is of most significance in the pre-asymptotic vicinity of the critical point and can be registered along certain thermodynamic paths. Its presence in the overall scattering pattern is demonstrated by our processing available experimental data for the depolarization factor. Some consequences of these results are discussed.

Power system technologies for the manned Mars mission

International Nuclear Information System (INIS)

Bents, D.; Patterson, M.J.; Berkopec, F.; Myers, I.; Presler, A.

1986-01-01

The high impulse of electric propulsion makes it an attractive option for manned interplanetary missions such as a manned mission to Mars. This option is, however, dependent on the availability of high energy sources for propulsive power in addition to that required for the manned interplanetary transit vehicle. Two power system technologies are presented: nuclear and solar. The ion thruster technology for the interplanetary transit vehicle is described for a typical mission. The power management and distribution system components required for such a mission must be further developed beyond today's technology status. High voltage-high current technology advancements must be achieved. These advancements are described. In addition, large amounts of waste heat must be rejected to the space environment by the thermal management system. Advanced concepts such as the liquid droplet radiator are discussed as possible candidates for the manned Mars mission. These thermal management technologies have great potential for significant weight reductions over the more conventional systems

Man and Cosmos from the Christian Theology perspective

Directory of Open Access Journals (Sweden)

Marin BUGIULESCU

2017-06-01

Full Text Available The purpose of this paper is to analyse the theological reflection on the relationship between man and cosmos. The origin of the world and man is connected to God; God is the Creator and consequently the Author of them both. Unlike dualistic materialistic thinking, according to the Christian conception the whole cosmos is created by God. In search for the cosmos an important chapter was granted for man, considered to be a synthesis of the world. Man, from the theological perspective, is the personal, rational, free, and speaking being that has – through the image of God according to which he has been created –, the tension after perfection. But it pertains exclusively to the relationship with Christ in the light of Whom he really knows himself, and by knowing himself he recognizes the infinite beauty of the Archetype. This is the existential-theological truth, which the content of this paper emphasizes, according to the Bible and patristic teaching.

MAN Nutzfahrzeuge AG (Munich, Federal Republic of Germany) always is eager to offer products for the respective markets whereby the products are interesting for the customer under economic criteria. Additionally, the products shall not lack in the travelling comfort under consideration of the legal emission borders. Thus, a AdBlue {sup registered} free technology for all MAN series was already offered before the legal introduction of EURO IV. This technology is based on an internal-motor solution with external, cooled AGR and a PM-Cat {sup registered} -filter. This solution is esteemed highly by our customers because apart from the well-known advantages in relation to a SCR technology there were no losses with the operating cost. With EURO V which is inserted in some countries MAN Nutzfahrzeuge AG returns to a long-term experience with SCR technology. The motivation for the development of a AdBlue {sup registered} free solution was the positive feedback of our customers on the basis of MAN EURO IV AGR/PM Cat technology. With the developed EURO V AGR solution, other EURO IV solutions in line with market conditions for the 'Emerging markets' can be derived with which a technology without exhaust post-treatment can be offered worldwide for our customers. This technology presents the basis for a platform concept EURO IV/V and EURO VI. In this concept, EURO IV can be presented without subsequent treatment of exhaust gases, EURO V in connection with an Oxicat and EURO VI with a SCRT system. Here, the vehicle/engine concept presents the most important components for the individual series in particular. By means of these components, the goal EURO V was achieved internal-motor without losses of operating cost and life span in relation to SCR technologies.

Experimental Observation of Negative Effective Gravity in Water Waves

2013-01-01

The gravity of Earth is responsible for the formation of water waves and usually difficult to change. Although negative effective gravity was recently predicted theoretically in water waves, it has not yet been observed in experiments and remains a mathematical curiosity which is difficult to understand. Here we experimentally demonstrate that close to the resonant frequency of purposely-designed resonating units, negative effective gravity can occur for water waves passing through an array of resonators composing of bottom-mounted split tubes, resulting in the prohibition of water wave propagation. It is found that when negative gravity occurs, the averaged displacement of water surface in a unit cell of the array has a phase difference of π to that along the boundary of the unit cell, consistent with theoretical predictions. Our results provide a mechanism to block water waves and may find applications in wave energy conversion and coastal protection. PMID:23715132

Radiation-induced chromosome aberrations in lymphocytes from man and crab-eating monkey

International Nuclear Information System (INIS)

Takahashi, E.; Hirai, M.; Tobari, I.; Utsugi, T.; Nakai, S.

1982-01-01

To obtain information on the relation between yield of chromosome aberrations and dose at low-dose levels, experiments were conducted with 5, 10, 20, 30 and 50 rad of 137 Cs γ-rays, on lymphocytes from man and crab-eating monkey (Macaca fascicularis). The dose-response relationship for dicentrics was obtained from the combined data of these low-dose experiments with those of our previous ones at high doses (100-400 rad). When the difference between observed yields and those expected from the linear-quadratic model were computed, the dose-response curve had a good fit for man, but not for the monkey. The linear regression lines between 0 and 30 rad were calculated, because the expected values of α/β for man and monkey would be about 100 and 60 rad. The human data gave a satisfactory fit to a linear model, i.e., a linear increase in aberration frequency with dose, whereas this was not so for those of the monkey. Furthermore, there was some suggestive evidence for the existence of a plateau in dicentric yields between 10 and 30 rad for the monkey and between 20 and 30 rad for human lymphocytes, but more data would be needed to verify this suggestion, particularly for human lymphocytes.

Experimental demonstration and visual observation of dust trapping in an electron storage ring

2009-11-01

Full Text Available Sudden decreases in the beam lifetime, which are attributed to the dust trappings, sometimes occur at the electron storage ring Photon Factory Advanced Ring (PF-AR. Since these dust events cause difficulties in user operations, we have been carefully observing this phenomenon for many years. Our observations indicated that the dust trappings could be caused by electric discharges in vacuum ducts. In order to demonstrate this hypothesis experimentally, we designed a new vacuum device that intentionally generates electric discharges and installed it in PF-AR. Using this device, we could repeatedly induce sudden decreases in the beam lifetime because of the generated electric discharge. We also detected decreases in the beam lifetime caused by mechanical movement of the electrodes in the device. Moreover, we could visually observe the dust trapping phenomenon; the trapped dust particle was observed by two video cameras and appeared as a luminous body that resembled a shooting star. This was the first direct observation of a luminous dust particle trapped by the electron beam.

1987-12-01

A preliminary feasibility study of the potential application of small nuclear reactor space power systems to manned planetary surface base missions was conducted. The purpose of the study was to identify and assess the technology, performance, and safety issues associated with integration of reactor power systems with an evolutionary manned planetary surface exploration scenario. The requirements and characteristics of a variety of human-rated modular reactor power system configurations selected for a range of power levels from 25 kWe to hundreds of kilowatts is described. Trade-off analyses for reactor power systems utilizing both man-made and indigenous shielding materials are provided to examine performance, installation and operational safety feasibility issues. The results of this study have confirmed the preliminary feasibility of a wide variety of small reactor power plant configurations for growth oriented manned planetary surface exploration missions. The capability for power level growth with increasing manned presence, while maintaining safe radiation levels, was favorably assessed for nominal 25 to 100 kWe modular configurations. No feasibility limitations or technical barriers were identified and the use of both distance and indigenous planetary soil material for human rated radiation shielding were shown to be viable and attractive options.

Its significance is at the point that Man can transform both his being andhis surroundings according to his own desires and aspirations. He actually makesimprovements upon what is created by God. God created night, he inventedthe lamp; God created clay, and from it he made the cup; God created deserts,mountains, forests, orchards, gardens, and groves. He makes glass out of stoneand turns poison into an antidote. God created the world, but he made it morebeautiful.Iqbal’s reasoning amply justifies belief in the ascendancy of man overthe universe and his predicted perfection. The perfect man is the ultimate endof the revolutionary process, and he is developed out of the present man, justas the full moon is developed from the crescent.

2017-11-01

We report on the first experimental observation of a current-driven instability developing in a quasineutral matter-antimatter beam. Strong magnetic fields (≥1 T ) are measured, via means of a proton radiography technique, after the propagation of a neutral electron-positron beam through a background electron-ion plasma. The experimentally determined equipartition parameter of ɛB≈10-3 is typical of values inferred from models of astrophysical gamma-ray bursts, in which the relativistic flows are also expected to be pair dominated. The data, supported by particle-in-cell simulations and simple analytical estimates, indicate that these magnetic fields persist in the background plasma for thousands of inverse plasma frequencies. The existence of such long-lived magnetic fields can be related to analog astrophysical systems, such as those prevalent in lepton-dominated jets.

Oedipus king: preparing man for the polis

Directory of Open Access Journals (Sweden)

José Joaquim Pereira Melo

2013-09-01

Full Text Available Having Sophoclean play Oedipus King as a frame of reference, the purpose of this paper is to discuss the educative proposal conceived to the Greek Man as preparation for life in the polis. Although not intentionally, Sophocles pointed out an ideal of Man which, in his perspective, would fulfill Greek societal demands of that time. Such society was divided between myth and rationality and, as a result, Man found Himself in conflict and lacking direction for His life. Given that, Oedipus’ character represented the ideal behavior of that society, and it also made it possible for citizens to reflect and to discuss social, economic and political transformations taking place at that period. Thus Sophocles came up with a hero who was an educational model and a citizen’s as well. Furthermore, such hero differed from that one of the archaic Greek thought.

Hydro-mechanical behaviour of a heterogeneous compacted soil: experimental observations and modelling

International Nuclear Information System (INIS)

Gens, A.; Vallejan, B.; Sanchez, M.; Imbert, C.; Villar, M.V.; Van Geet, M.

2011-01-01

The paper describes a theoretical and experimental study of the coupled hydro-mechanical behaviour of a compacted mixture of bentonite powder and bentonite pellets intended as sealing material in underground repositories for nuclear waste. One of the main advantages of the use of powder/pellets mixtures is the reduction of the compaction effort required to achieve the value of average dry density necessary to attain the required swelling potential. However, the heterogeneous fabric of the material requires special approaches in order to describe adequately its behaviour during hydration. A double porosity formulation is presented to account for the presence of two distinct structural levels in the material. Hydraulic equilibrium between the two porosities is not assumed; instead a water exchange term between them is postulated. The formulation is applied to the modelling of a number of one-dimensional swelling pressure tests performed in the CEA (Commissariat a l'Energie Atomique, France) and CIEMAT (Spain) laboratories. A very satisfactory quantitative description of the experimental observations is obtained that includes a number of complex behaviour features such as size effects and non-monotonic development of swelling pressures. Some micro-fabric observations using X-ray tomography and mercury intrusion porosimetry lend support to the conceptual approach adopted. The formulation is then applied to the analysis of a long-term large-scale sealing test performed at the Hades underground facility in Belgium, using the same set of hydraulic and mechanical parameters employed in the modelling of the laboratory tests. Although the field observations exhibit a much higher degree of scatter, the basic behaviour of the field sealing test is satisfactorily simulated. A formulation that incorporates basic features of the micro-fabric of the mixture is thus able to span successfully over a large range of space and time scales. (authors)

The advent of widely available nanoscale energetic composites has resulted in a flurry of novel applications. One of these applications is the use of nanomaterials in energetic compositions. In compositions that exhibit high sensitivity to stimulus, these materials are often termed metastable intermolecular composites (MIC). More generally, these compositions are simply called nanoenergetics. Researchers have used many different experimental techniques to analyze the various properties of nanoenergetic systems. Among these various techniques, the confined tube burn is a simple experiment that is capable of obtaining much data related to the combustion of these materials. The purpose of this report is to review the current state of the confined tube burn experiment, including the drawbacks of the technique and possible remedies. As this report is intended to focus on the specific experimental technique, data from many different energetic materials, and experimental configurations will be presented. The qualitative and quantitative data that can be gathered using confined tube burn experiments include burning rates, total impulse, pressure rise rate, and burning rate differences between different detector types. All of these measurements lend insight into the combustion properties and mechanisms of specific nanoenergetics. Finally, certain data indicates a more complicated flow scenario which may need to be considered when developing burn tube models.

Physical characteristics of the Japanese in relation to reference man

Quantitative description of physical and other characteristics of the human body provides basic data for the estimation of radiation risk and the establishment of dose equivalent in line with the International Commission on Radiological Protection recommendations. ICRP Reference Man is based essentially on data reported on populations in rather limited areas in the world although Committee 2 of ICRP concedes that ''it is neither feasible nor necessary to specify Reference Man as representative of a well-defined population group''. ICRP Reference Man is not necessarily based on the most recent available data. In order to be more realistic and quantitative in dose equivalent estimation in Japan, it is necessary to consider populations which are largely different from those of European and North American countries in physical dimensions and other aspects. Therefore, standard or reference values of mass and size of organs, body and organ content and metabolic parameters of some elements have been studied. These are compared with the values of ICRP Reference Man authorized up to now, with the intention of establishing ''Reference Japanese Man'' and contributing to the improvement of models of man used in radiation protection. Dose equivalent commitment and annual limit of intake have been calculated using the obtained data for the general population in Japan,for some nuclides. (H.K.)

Experimental Observation of Two Features Unexpected from the Classical Theories of Rubber Elasticity

2017-12-01

Although the elastic modulus of a Gaussian chain network is thought to be successfully described by classical theories of rubber elasticity, such as the affine and phantom models, verification experiments are largely lacking owing to difficulties in precisely controlling of the network structure. We prepared well-defined model polymer networks experimentally, and measured the elastic modulus G for a broad range of polymer concentrations and connectivity probabilities, p . In our experiment, we observed two features that were distinct from those predicted by classical theories. First, we observed the critical behavior G ˜|p -pc|1.95 near the sol-gel transition. This scaling law is different from the prediction of classical theories, but can be explained by analogy between the electric conductivity of resistor networks and the elasticity of polymer networks. Here, pc is the sol-gel transition point. Furthermore, we found that the experimental G -p relations in the region above C* did not follow the affine or phantom theories. Instead, all the G /G0-p curves fell onto a single master curve when G was normalized by the elastic modulus at p =1 , G0. We show that the effective medium approximation for Gaussian chain networks explains this master curve.

Existing research on the extensive Chinese censorship organization uses observational methods with well-known limitations. We conducted the first large-scale experimental study of censorship by creating accounts on numerous social media sites, randomly submitting different texts, and observing from a worldwide network of computers which texts were censored and which were not. We also supplemented interviews with confidential sources by creating our own social media site, contracting with Chinese firms to install the same censoring technologies as existing sites, and--with their software, documentation, and even customer support--reverse-engineering how it all works. Our results offer rigorous support for the recent hypothesis that criticisms of the state, its leaders, and their policies are published, whereas posts about real-world events with collective action potential are censored.

In the present work, we optimised and evaluated a qPCR system integrating 6-FAM (6-carboxyfluorescein)-labelled TaqMan probes and melting analysis using the SYTO 82 (S82) DNA binding dye in a single reaction. We investigated the influence of the S82 on various TaqMan and melting analysis parameters and defined its optimal concentration. In the next step, the method was evaluated in 36 different TaqMan assays with a total of 729 paired reactions using various DNA and RNA templates, including field specimens. In addition, the melting profiles of interest were correlated with the electrophoretic patterns. We proved that the S82 is fully compatible with the FAM-TaqMan system. Further, the advantages of this approach in routine diagnostic TaqMan qPCR were illustrated with practical examples. These included solving problems with flat or other atypical amplification curves or even false negativity as a result of probe binding failure. Our data clearly show that the integration of the TaqMan qPCR and melting analysis into a single assay provides an additional control option as well as the opportunity to perform more complex analyses, get more data from the reactions, and obtain analysis results with higher confidence.

The universe has always aroused people's curiosity. It fascinates and at the same time scares in its vastness. Encourages us to reflect of the meaning of human life. This begs the questions: whether there is a life beyond Earth? Whether is it possible that the man is alone in such a large space? These questions still remain unanswered, and topics concerning "the cosmos" constantly evoke many emotions. It is especially fascinating for the youngest students. Quite often, preschoolers can flawlessly name the planets according to their order of appearance in relation to the sun. They are happy to take the fun inspired by journeys into space. Teaching through action is extremely important for the development of the child-man* (Piaget, 2006). The thinking originates primarily from the action. Therefore, students should undertake independent research activities, perform experiments and conduct observations and thus raise questions about the world, looking for meanings and solutions. Adults (a teacher, a person with a passion) are to be the support in the search for knowledge, its processing and cleaning. Its role is to ensure a proper development of environment that is conducive to research activity. The answer to these requirements was to create in the oldest technical school in Poland (Railway Technical College, now Technical College No. 7) the astronomical observatory, which can be used by pupils of Warsaw's kindergartens and schools. There are organized activities for children and youth in this school, as well as trainings for teachers. Younger students during such an interdisciplinary courses are, among others, the opportunity to get acquainted with the construction of the telescope, they can build their own rockets and organize their racing or create your own star constellations. Older students as a result of observations and experiments may confirm or refute the hypothesis that the universe is within each of us. The classes are enriched using applications on

Structure-driven turbulence in ``No man's Land''

Science.gov (United States)

Kosuga, Yusuke; Diamond, Patrick

2012-10-01

Structures are often observed in many physical systems. In tokamaks, for example, such structures are observed as density blobs and holes. Such density blobs and holes are generated at the tokamak edge, where strong gradient perturbations generate an outgoing blob and an incoming hole. Since density holes can propagate from the edge to the core, such structures may play an important role in understanding the phenomenology of the edge-core coupling region, so-called ``No Man's Land.'' In this work, we discuss the dynamics of such structures in real space. In particular, we consider the dynamics of density blobs and holes in the Hasegawa-Wakatani system. Specific questions addressed here include: i) how these structures extract free energy and enhance transport? how different is the relaxation driven by such structures from that driven by linear drift waves? ii) how these structures interact with shear flows? In particular, how these structures interact with a shear layer, which can absorb structures resonantly? iii) how can we calculate the coupled evolution of structures and shear flows? Implications for edge-core coupling problem are discussed as well.

We report on the first experimental observation of a current-driven instability developing in a quasineutral matter-antimatter beam. Strong magnetic fields (≥1  T) are measured, via means of a proton radiography technique, after the propagation of a neutral electron-positron beam through a background electron-ion plasma. The experimentally determined equipartition parameter of ε_{B}≈10^{-3} is typical of values inferred from models of astrophysical gamma-ray bursts, in which the relativistic flows are also expected to be pair dominated. The data, supported by particle-in-cell simulations and simple analytical estimates, indicate that these magnetic fields persist in the background plasma for thousands of inverse plasma frequencies. The existence of such long-lived magnetic fields can be related to analog astrophysical systems, such as those prevalent in lepton-dominated jets.

Effect of Variable Manning Coefficients on Tsunami Inundation

Science.gov (United States)

Barberopoulou, A.; Rees, D.

2017-12-01

Numerical simulations are commonly used to help estimate tsunami hazard, improve evacuation plans, issue or cancel tsunami warnings, inform forecasting and hazard assessments and have therefore become an integral part of hazard mitigation among the tsunami community. Many numerical codes exist for simulating tsunamis, most of which have undergone extensive benchmarking and testing. Tsunami hazard or risk assessments employ these codes following a deterministic or probabilistic approach. Depending on the scope these studies may or may not consider uncertainty in the numerical simulations, the effects of tides, variable friction or estimate financial losses, none of which are necessarily trivial. Distributed manning coefficients, the roughness coefficients used in hydraulic modeling, are commonly used in simulating both riverine and pluvial flood events however, their use in tsunami hazard assessments is primarily part of limited scope studies and for the most part, not a standard practice. For this work, we investigate variations in manning coefficients and their effects on tsunami inundation extent, pattern and financial loss. To assign manning coefficients we use land use maps that come from the New Zealand Land Cover Database (LCDB) and more recent data from the Ministry of the Environment. More than 40 classes covering different types of land use are combined into major classes such as cropland, grassland and wetland representing common types of land use in New Zealand, each of which is assigned a unique manning coefficient. By utilizing different data sources for variable manning coefficients, we examine the impact of data sources and classification methodology on the accuracy of model outputs.

Conference on Manned Systems Design : New Methods and Equipment

Kraiss, K-F

1981-01-01

This volume contains the proceedings of a conference held in Freiburg, West Germany, September 22-25, 1980, entitled "Manned Systems Design, New Methods and Equipment". The conference was sponsored by the Special Programme Panel on Human Factors of the Scientific Affairs Division of NATO, and supported by Panel VIII, AC/243, on "Human and Biomedical Sciences". Their sponsorship and support are gratefully acknowledged. The contributions in the book are grouped according to the main themes of the conference with special emphasis on analytical approaches, measurement of performance, and simulator design and evaluat ion. The design of manned systems covers many and highly diversified areas. Therefore, a conference under the general title of "Manned Systems Design" is rather ambitious in itself. However, scientists and engineers engaged in the design of manned systems very often are confronted with problems that can be solved only by having several disciplines working together. So it was felt that knowledge about ...

1981-01-01

137 Cs has been determined in man with the aid of a whole-body counter. It is shown that the specific 137 Cs content (as related to the potassium content in man) continuously decreased from 1965 through 1974. After a slight increase in 1975, possibly caused by a Chinese atmospheric nuclear test in June 1974, the 137 Cs content again decreased in the following years. (author)

Man-midwifery history: 1730-1930.

Science.gov (United States)

Shelton, D C

2012-11-01

This paper seeks to determine whether the man-midwives William Smellie and William Hunter deserve continuing approbation as 'Founding Fathers' of the obstetrics profession. Scrutiny of their careers reveals their involvement in murders for dissection. In addition, the man-midwifery initiative of delivery in lying-in hospitals resulted in around 1 million more deaths in Britain and Ireland between 1730 and 1930, than would have occurred had home-births remained as the norm. While some may still credit Smellie and Hunter with obstetric discoveries, their knowledge was obtained by murder-for-dissection. That indictment, together with the lying-in hospital legacy, far outweighs their discoveries. The paper invites further constructive discussion and debate, but concludes the accolade of Founding Fathers is undeserved. Any continuing endorsement of Smellie and Hunter effectively demeans the high ethical standards and reputation of current obstetric professionals.

The discussion of cultural and sociological consequences of computer evolution is hindered by human prejudice. For example the sentence 'a computer is at best as intelligent as its programmer' veils actual developments. Theoretical limits of computer intelligence are the limits of intelligence in general. Modern computer systems replace not only human labour, but also human decision making and thereby human responsibility. The historical situation is unique. Human head-work is being automated and man is loosing function. (orig.) [de

Objective: To observe the radiation injury of the bowel wall due to the implantation of interstitial 125 I seeds in experimental dogs. Methods: A total of 12 healthy male dogs were randomly and equally divided into 3 experimental groups and 1 control group, with 3 dogs in each group.In the experimental groups, two 125 I seeds with the active radiation dose of 0.8mCi were symmetrically implanted under the serous membrane of the dog's small intestinal wall. The dogs were fed for 14 days (group A), for one month (group B) and for two months (group C) respectively when the animals were scheduled to be sacrificed. The dogs' general condition was observed till they were sacrificed. The seed-implanting intestinal segments were then removed and dyed with HE staining method for electronic microscopic exam. The histopathologic findings were recorded and the results were compared between four groups. Results: No obvious histopathological changes were found in the dog's bowel wall 14 days after the implantation. One month after the procedure cellular injury was observed under electronic microscope, and two months after the operation partial fibrosis of the intestinal wall appeared but no ulceration or perforation occurred. Conclusion: The implantation of 125 I seeds can cause reversible cellular injuries of the intestinal wall in experimental dogs, the degree of the damage reaches its peak at one month after the implant when the partial fibrosis of bowel wall becomes evident. However, the seeds do not cause any serious complications, such as ulceration or perforation. (authors)

1999-03-01

Long-term manned space missions are planned to be implemented within the first two decades of the 21st century. The International Space Station (ISS) will be ready to run, and a plan to visit Mars is also under way. Humans will live in space for long periods of time and we are planning to do experiments in space to examine various aspects of space science. The main risk in long-term manned space missions is large exposure to space radiation. Human safety must be ensured in space where exposure to cosmic rays is almost 1 mSv a day. As such missions will inevitably result in significant exposure for astronauts, there is increasing need to protect them adequately based on both physical and biological knowledge. A good method to evaluate realistic risk associated with space missions will be in urgent demand. At the National Institute of Radiological Sciences (NIRS), Chiba, Japan, a research institutes of the Science Technology Agency of Japan, high energy cosmic radiation can be simulated only with heavy ion irradiation accelerated by the particle accelerator, Heavy Ion Medical Accelerator (HIMAC). Research to evaluate risk of space radiation, including physical measurement techniques, protective effects, biological effects and risk adjustment, aging, neuronal cell damage and cancer risk are undergoing. We organized a workshop of the latest topics and experimental results of physics and biology related to space radiation supported by Japan Science and Technology Corporation (JST). This workshop was held as a satellite meeting associated with the 32nd Committee on Space Research (COSPAR) Scientific Assembly (Nagoya, July 12-19th, 1998). This volume is an extended proceedings of the workshop. The proceedings contain six main subjects covering the latest information on Risk Evaluation of Cosmic-Ray Exposure in Long-Term Manned Space Mission'. 1. Risk Estimation of Heavy Ion Exposure in Space. 2. Low Dose-Rate Effects and Microbeam-Related Heavy Ions. 3. Chromosome and

"I Am Chelsea Manning": Comparison of Gendered Representation of Private Manning in U.S. and International News Media.

On August 22, 2013, Bradley Manning released a statement requesting to be referred to as female. In the following days, the news media discussed whether language should shift toward a female representation. Using quantitative content analysis and qualitative contextual analysis, this study analyzed whether U.S. and international newspapers (N = 197) acknowledged Manning's request to be referred to as "Chelsea" in the two weeks after the statement. Results suggest that the mainstream press was hesitant in shifting toward a female representation. A comparison of international and U.S. newspapers suggests that the U.S. press lagged behind international coverage using a female depiction.

2015-01-01

The experimental observation of cumulative second-harmonic generation of the primary circumferential guided wave propagation is reported. A pair of wedge transducers is used to generate the primary circumferential guided wave desired and to detect its fundamental-frequency and second-harmonic amplitudes on the outside surface of the circular tube. The amplitudes of the fundamental waves and the second harmonics of the circumferential guided wave propagation are measured for different separations between the two wedge transducers. At the driving frequency where the primary and the double-frequency circumferential guided waves have the same linear phase velocities, the clear second-harmonic signals can be observed. The quantitative relationships between the second-harmonic amplitudes and circumferential angle are analyzed. It is experimentally verified that the second harmonics of primary circumferential guided waves do have a cumulative growth effect with the circumferential angle. (paper)

An immunocompromised man presented with an inflammatory eyelid lesion. Biopsy was performed; histopathology and special staining confirmed a diagnosis of bacillary angiomatosis. The man was treated with oral erythromycin, and the lesion resolved. The etiologic agents of bacillary angiomatosis are Bartonella henselae and Bartonella quintana, Gram-negative coccobacilli. The organisms stain positively with the Warthin-Starry silver stain. Lesions can be cutaneous or visceral and have been commonly described in immunocompromised patients. Histopathologic examination of lesions reveals angiogenesis and cellular proliferation. Bacillary angiomatosis can be treated with oral antibiotics.

This paper gives an overview of the current state of the art in man-machine system interaction studies, focusing on the problems derived from highly automated working environments and the role of humans in the control loop. In particular, it is argued that there is a need for sound approaches to the design and analysis of man-machine interaction (MMI), which stem from the contribution of three expertises in interfacing domains, namely engineering, computer science and psychology: engineering for understanding and modelling plants and their material and energy conservation principles; psychology for understanding and modelling humans an their cognitive behaviours; computer science for converting models in sound simulations running in appropriate computer architectures.

Sehlstedt Maria

2010-08-01

Full Text Available Abstract Background Biomass combustion contributes to the production of ambient particulate matter (PM in rural environments as well as urban settings, but relatively little is known about the health effects of these emissions. The aim of this study was therefore to characterize airway responses in humans exposed to wood smoke PM under controlled conditions. Nineteen healthy volunteers were exposed to both wood smoke, at a particulate matter (PM2.5 concentration of 224 ± 22 μg/m3, and filtered air for three hours with intermittent exercise. The wood smoke was generated employing an experimental set-up with an adjustable wood pellet boiler system under incomplete combustion. Symptoms, lung function, and exhaled NO were measured over exposures, with bronchoscopy performed 24 h post-exposure for characterisation of airway inflammatory and antioxidant responses in airway lavages. Results Glutathione (GSH concentrations were enhanced in bronchoalveolar lavage (BAL after wood smoke exposure vs. air (p = 0.025, together with an increase in upper airway symptoms. Neither lung function, exhaled NO nor systemic nor airway inflammatory parameters in BAL and bronchial mucosal biopsies were significantly affected. Conclusions Exposure of healthy subjects to wood smoke, derived from an experimental wood pellet boiler operating under incomplete combustion conditions with PM emissions dominated by organic matter, caused an increase in mucosal symptoms and GSH in the alveolar respiratory tract lining fluids but no acute airway inflammatory responses. We contend that this response reflects a mobilisation of GSH to the air-lung interface, consistent with a protective adaptation to the investigated wood smoke exposure.

Seeing mental states: An experimental strategy for measuring the observability of other minds

Science.gov (United States)

Becchio, Cristina; Koul, Atesh; Ansuini, Caterina; Bertone, Cesare; Cavallo, Andrea

2018-03-01

Is it possible to perceive others' mental states? Are mental states visible in others' behavior? In contrast to the traditional view that mental states are hidden and not directly accessible to perception, in recent years a phenomenologically-motivated account of social cognition has emerged: direct social perception. However, despite numerous published articles that both defend and critique direct perception, researchers have made little progress in articulating the conditions under which direct perception of others' mental states is possible. This paper proposes an empirically anchored approach to the observability of others' mentality - not just in the weak sense of discussing relevant empirical evidence for and against the phenomenon of interest, but also, and more specifically, in the stronger sense of identifying an experimental strategy for measuring the observability of mental states and articulating the conditions under which mental states are observable. We conclude this article by reframing the problem of direct perception in terms of establishing a definable and measurable relationship between movement features and perceived mental states.

TaxMan: a taxonomic database manager

Directory of Open Access Journals (Sweden)

Blaxter Mark

2006-12-01

Full Text Available Abstract Background Phylogenetic analysis of large, multiple-gene datasets, assembled from public sequence databases, is rapidly becoming a popular way to approach difficult phylogenetic problems. Supermatrices (concatenated multiple sequence alignments of multiple genes can yield more phylogenetic signal than individual genes. However, manually assembling such datasets for a large taxonomic group is time-consuming and error-prone. Additionally, sequence curation, alignment and assessment of the results of phylogenetic analysis are made particularly difficult by the potential for a given gene in a given species to be unrepresented, or to be represented by multiple or partial sequences. We have developed a software package, TaxMan, that largely automates the processes of sequence acquisition, consensus building, alignment and taxon selection to facilitate this type of phylogenetic study. Results TaxMan uses freely available tools to allow rapid assembly, storage and analysis of large, aligned DNA and protein sequence datasets for user-defined sets of species and genes. The user provides GenBank format files and a list of gene names and synonyms for the loci to analyse. Sequences are extracted from the GenBank files on the basis of annotation and sequence similarity. Consensus sequences are built automatically. Alignment is carried out (where possible, at the protein level and aligned sequences are stored in a database. TaxMan can automatically determine the best subset of taxa to examine phylogeny at a given taxonomic level. By using the stored aligned sequences, large concatenated multiple sequence alignments can be generated rapidly for a subset and output in analysis-ready file formats. Trees resulting from phylogenetic analysis can be stored and compared with a reference taxonomy. Conclusion TaxMan allows rapid automated assembly of a multigene datasets of aligned sequences for large taxonomic groups. By extracting sequences on the basis of

Full Text Available Indonesian marriage states that marriage is physical and spiritual relationship between a man and a woman as husband and wife in order to create an eternal happy family based on the Almighty God. This definition reflects that the marriage in Indonesia must be between heterosexual couple. However, a question appears as to whether a man or a woman mentioned thereof is included a man and a woman who were, hermaphrodite, intersex, or nowadays known as person with Disorder of Sexual Development (DSD? The case of AH whereby his marriage is cancelled by the Supreme Court in 2014 for he is not considered as a man, is confirming that this question is important to value the capacity of a person to marry. This writing will apply normative research as well as literature research method upon the positive rules and regulations. The decisions of district courts upon the revision or change of gender and its legal basis will be analysed and be the topic of discussion. Comparison will be applied to compare the marriage requirements between Indonesian Law, Singapore Law and Hong Kong Law. The results of analyse and discussion will be the closure of the writing, as conclusions and advise, if any.

In the near future, distributed autonomous systems will be practical in many situations, e.g., interactive production systems, hazardous environments, nursing homes, and individual houses. The agents which consist of the distributed system must not give damages to human being and should be working economically. In this project man-machine cooperative multi agent systems are studied in many kind of respects, and basic design technology, basic control technique are developed by establishing fundamental theories and by constructing experimental systems. In this project theoretical and experimental studies are conducted in the following sub-projects: (1) Distributed cooperative control in multi agent type actuation systems (2) Control of non-holonomic systems (3) Man-machine Cooperative systems (4) Robot systems learning human skills (5) Robust force control of constrained systems In each sub-project cooperative nature between machine agent systems and human being, interference between artificial multi agents and environment and new function emergence in coordination of the multi agents and the environment, robust force control against for the environments, control methods for non-holonomic systems, robot systems which can mimic and learn human skills were studied. In each sub-project, some problems were hi-lighted and solutions for the problems have been given based on construction of experimental systems. (NEDO)

The CANDU man-machine interface and simulator training

1982-09-01

The most significant features of the man-machine interface for CANDU power stations are the extensive use of computer-driven colour graphics displays and the small number of manual controls. The man-machine interface in CANDU stations is designed to present the operator with concise, easy-to-understand information. Future developments in the use of computers in safety shutdown systems, and the use of data highway technologies in plant regulating systems will present special requirements and new opportunities in the application of human factors engineering to the control room. Good man-machine interaction depends on operator training as much as on control room design. In Canada computerized training simulators, which indicate plant response to operator action, are being introducted for operator training. Such simulators support training in normal operation of all plant systems and also in the fault management tasks following malfunctions

The collation and generation of data on physical, anatomical, physiological and metabolic characteristics of Indian subjects were carried out to set up a Reference Indian Man for radiation protection. A comparison of the Reference Indian Man data with the corresponding data for ICRP Reference Man, clearly showed that the physical, anatomical and metabolic characteristics were in general smaller for Reference Indian Man. A few of the physiological characteristics such as the daily consumption of drinking water, sweat rate were however, found to be higher, and the minute volume was similar for Reference Indian, in comparison to the ICRP Reference Man. The details of various human characteristics representative of the Indian population are reported in this paper. (author). 43 refs., 25 tabs., 6 figs.

Not normally manned compression platforms for the North Sea

International Nuclear Information System (INIS)

Kumaran, K.S.

1994-01-01

Gas turbine driven gas compressors have been widely used on manned offshore facilities. Similarly unmanned gas turbine driven compressor stations have been in operation onshore with major gas transmission companies in Europe, North America and elsewhere. This paper summarizes a recent joint industry study to investigate the technical and economic feasibility of Not Normally Manned (NNM) Offshore Compression Facilities in terms of reliability, availability and maintainability. Classification of not normally manned (or unmanned) offshore facilities in the UK North Sea is in accordance with HSE Operations Notice 8. ON8 specifies criteria for offshore visits, visit hours and number of personnel on board for the operation of NNM platforms. This paper describes a typical Southern North Sea gas platform being considered for NNM compressor application. The conclusions from the study was that NNM compression is technically feasible with the facilities being able to provide an availability in excess of 98%. Life cycle costs were of the order of 70% of manned facilities thus significantly improving field development economics

Space nuclear reactor shields for manned and unmanned applications

International Nuclear Information System (INIS)

McKissock, B.I.; Bloomfield, H.S.

1990-01-01

Missions which use nuclear reactor power systems require radiation shielding of payload and/or crew areas to predetermined dose rates. Since shielding can become a significant fraction of the total mass of the system, it is of interest to show the effect of various parameters on shield thickness and mass for manned and unmanned applications. Algorithms were developed to give the thicknesses needed if reactor thermal power, separation distances and dose rates are given as input. The thickness algorithms were combined with models for four different shield geometries to allow tradeoff studies of shield volume and mass for a variety of manned and unmanned missions. The shield design tradeoffs presented in this study include the effects of: higher allowable dose rates; radiation hardened electronics; shorter crew exposure times; shield geometry; distance of the payload and/or crew from the reactor; and changes in the size of the shielded area. Specific NASA missions that were considered in this study include unmanned outer planetary exploration, manned advanced/evolutionary space station and advanced manned lunar base. (author)

[Albert Schweitzer. The man as a symbol].

Science.gov (United States)

Urdaneta-Carruyo, Eliexer

2007-01-01

Albert Schweitzer, the great missionary physician from the XXth century, had a versatile personality that integrated multiple talents, leading to the slightly frequent conjunction of the thinker with the man of action, and the humanist with the scientist and the artist. He studied all these disciplines in a brilliant manner: Philosophy, Theology, Music and Medicine; he was also a great scholar of Bach's work, Jesus Christ and the civilization history. In his maturity, this great man renounced to the fame and glory gained as intellectual and musician, to dedicate his life as a physician for the forgotten African natives. His deeply religious spirit allowed him to penetrate into the most recondite of the human soul; in his personality, he expressed in its entire dimension the eternally unsatisfied desire of the solitary man, against the immensity of the universe. His philosophy, based on the respect for life, was realized throughout the practice of the medical profession. His noble character and personality was based on the man as symbol, since it was not so much what he did helping people but what people could do to others due to him. His singular example represented a moral force in the world, superior to millions of men armed for a war. In 1953, he received the Nobel Peace Prize for his philanthropic work in Africa during more that fifty years, and for his deep love to the living beings. He was transformed in a perennial legend as the Lambaréné doctor.

To design a new TaqMan® MGB probe for improving the specificity of Streptococcus mutans's detection. We extracted six DNA samples from different streptococcal strains for PCR reaction. Conventional nested PCR and TaqMan® MGB real-time PCR were applied independently. The first round of nested PCR was carried out with the bacterial universal primers, while a second PCR was conducted by using primers specific for the 16S rRNA gene of Streptococcus mutans. The TaqMan® MGB probe for Streptococcus mutans was designed from sequence analyses, and the primers were the same as nested PCR. Streptococcus mutans DNA with 2.5 mg/L was sequentially diluted at 5-fold intervals to 0.16 μg/L. Standard DNA samples were used to generate standard curves by TaqMan® MGB real-time PCR. In the nested PCR, the primers specific for Streptococcus mutans also detected Streptococcus gordonii with visible band of 282 bp, giving false-positive results. In the TaqMan® MGB real-time PCR reaction, only Streptococcus mutans was detected. The detection limitation of TaqMan® MGB real-time PCR for Streptococcus mutans 16S rRNA gene was 20 μg/L. We designed a new TaqMan® MGB probe, and successfully set up a PCR based method for detecting oral Streptococcus mutans. TaqMan® MGB real-time PCR is a both specific and sensitive bacterial detection method.

Mass of organs and composition of the body of Japanese Reference Man

1990-01-01

Reference Man as defined and described in ICRP Publication 23 is in the process of major revision, with an emphasis on the age and sex, and characteristics of non-European populations. Japanese Reference Man (or Woman) is to be defined as the subject, normal and healthy, 20 to 30 years of age, who inhabits in Japan and live on the 'standard diet'. He (or she) is a Mongoloid in race, and 170 (or 160) cm in height, and 60 (or 51) kg in weight. Physical properties such as masses of 114 organs, tissues and components, and their specific gravities of Japanese Reference Male are given. Body composition or body fat, LBM, skeleton, soft lean body mass (SLBM), body water, blood, muscle, ash, protein and specific gravity were also given as well as body surface. These data are primarily based on the data obtained for normal Japanese, and, where data unavailable, they were derived from ICRP Reference Man data by using a new concept of SLBM. Red bone marrow was estimated to be 1,000g as compared to 1,500g in Reference Man. Body fat was obtained by using Nagamine's equations, which showed a recent slight tendency of obesity. In conclusion, the present data for Japanese Reference Man could be used in designing appropriate phantoms, mathematical and real, for Japanese. Japanese Reference Man will also provide a basis for Asian Reference Man, which, in principle, should be consistent with ICRP concepts of Reference Man. (author)

The colour of thermal noise in classical Brownian motion: a feasibility study of direct experimental observation

International Nuclear Information System (INIS)

Berg-Soerensen, Kirstine; Flyvbjerg, Henrik

2005-01-01

One hundred years after Einstein modelled Brownian motion, a central aspect of this motion in incompressible fluids has not been verified experimentally: the thermal noise that drives the Brownian particle, is not white, as in Einstein's simple theory. It is slightly coloured, due to hydrodynamics and the fluctuation-dissipation theorem. This theoretical result from the 1970s was prompted by computer simulation results in apparent violation of Einstein's theory. We discuss how a direct experimental observation of this colour might be carried out by using optical tweezers to separate the thermal noise from the particle's dynamic response to it. Since the thermal noise is almost white, very good statistics is necessary to resolve its colour. That requires stable equipment and long recording times, possibly making this experiment one for the future only. We give results for experimental requirements and for stochastic errors as functions of experimental window and measurement time, and discuss some potential sources of systematic errors

[Man's place and anthropology in bioethics].

Science.gov (United States)

Tomar Romero, Francisca

2013-01-01

From the analysis of its epistemological status, the article focuses on the philosophical fundament of bioethics, stressing the need for an authentic anthropology as a reference or starting point. Being an applied ethics, the first fundament of bioethics is in ethics. It shows how only personalistic ethics, which takes as reference the nature or essence of man, can offer objective and universal criteria. Philosophical anthropology studies man as a whole, in an integral manner, from the perspective of its nature or fundamental aspects of his being. It analyzes the distinction and relationship between the philosophical anthropology and the positive anthropologies, as well as with the physical, human and social sciences. Finally, it reflects on the current anthropological crisis and its ethical consequences.

Experimental observation of pulsating instability under acoustic field in downward-propagating flames at large Lewis number

KAUST Repository

Yoon, Sung Hwan

2017-10-12

According to previous theory, pulsating propagation in a premixed flame only appears when the reduced Lewis number, β(Le-1), is larger than a critical value (Sivashinsky criterion: 4(1 +3) ≈ 11), where β represents the Zel\\'dovich number (for general premixed flames, β ≈ 10), which requires Lewis number Le > 2.1. However, few experimental observation have been reported because the critical reduced Lewis number for the onset of pulsating instability is beyond what can be reached in experiments. Furthermore, the coupling with the unavoidable hydrodynamic instability limits the observation of pure pulsating instabilities in flames. Here, we describe a novel method to observe the pulsating instability. We utilize a thermoacoustic field caused by interaction between heat release and acoustic pressure fluctuations of the downward-propagating premixed flames in a tube to enhance conductive heat loss at the tube wall and radiative heat loss at the open end of the tube due to extended flame residence time by diminished flame surface area, i.e., flat flame. The thermoacoustic field allowed pure observation of the pulsating motion since the primary acoustic force suppressed the intrinsic hydrodynamic instability resulting from thermal expansion. By employing this method, we have provided new experimental observations of the pulsating instability for premixed flames. The Lewis number (i.e., Le ≈ 1.86) was less than the critical value suggested previously.

[Observation of antiarrhythmic effects of Cinnamomum migao H. W. Li on experimental arrhythmia].

Science.gov (United States)

Sui, Y; Qiu, D; Xie, C; Chen, K

1998-08-01

To investigate the effects of Cinnamomum migao on experimental arrhythmia. Arrhythmic models of mice, rabbits, guinea pigs and rats were built using chloroform(Chl), adrenalin(Adr), strophanthin-K (Spt-K) and barium chloride (BaCl2). The affected animals were divided randomly into three groups: control group, Cinnamomum migao (CV-3) group and mexiletine (MXL) group, so as to observe and compare the antiarrhythmic effects. CV-3 could reduce the incidence of ventricular fibrillation caused by ch1 in mice and the ventricular tachycardia induced by Adr in rabbits, delay the onset time of this arrhythmia, increase the arrhythmic doses of Spt-K in guinea pigs, reduce the incidence of some arrhythmia caused by BaCl2 in rats and slow down their heart rate. CV-3 has obvious antiarrhythmic effects on experimental arrhythmia. The mechanism of these effects is probably related to the arrest of the intraflow of Na+, Ca2+ in the cardiac cells and the depression of their cardiac autoarrhythmicity and conductivity.

Propulsive options for a manned Mars transportation system

In this investigation, five potential manned Mars transportation systems are compared. These options include: (1) a single vehicle, chemically propelled (CHEM) option, (2) a single vehicle, nuclear thermal propulsion (NTP) option, (3) a single vehicle solar electric propulsion (SEP) option, (4) a single vehicle hybrid nuclear electric propulsion (NEP)/CHEM option, and (5) a dual vehicle option (NEP cargo spacecraft and CHEM manned vehicle). In addition to utilizing the initial vehicle weight in low-earth orbit as a measure of mission feasibility, this study addresses the major technological barriers each propulsive scenario must surpass. It is shown that instead of a single clearly superior propulsion system, each means of propulsion may be favored depending upon the specified program policy and the extent of the desired manned flight time. Furthermore, the effect which aerobraking and multiple transfer cycles have upon mission feasibility is considered. 18 refs

Full Text Available The dissemination and exploitation of cultural heritage milestones by using multimedia and interactive technologies continuously and quickly grows capturing the attention of academia and companies. It is necessary to adopt the state of the art technologies to present and make bi-directional the interaction of users with cultural heritage objects. In this work, we present two different applications of novel technologies applied to the Vitruvian man of Leonardo. The first application is the mirror that exploits a 3D depth sensor to compare the proportions of a user with the perfect ones of the Vitruvian man. The second application is a complex interaction between a complete novel 3D model of the Leonardo’s Vitruvian Man, sounds and image effects inside a 360-degrees hologram. These two systems are the results of interaction between academia and the 3D EVE spin-off company.

Thoughts on the cultural evolution of man. Developmental imprinting and transgenerational effect.

Science.gov (United States)

Csaba, György

2007-01-01

The biological evolution of man stopped since it has been conveyed to the objects, created by man. This paper introduces the concept of "conveyed evolution". Being part of the cultural evolution, the conveyed evolution is a continuation of the biological one. There are several similarities between the laws of biological and conveyed evolution, albeit the differences are important as well. Some laws of the conveyed evolution are described here. The conveyed evolution has man-made repair mechanisms (medicine, protection of environment) which defend man from harm. Man's fragility limits the progress of conveyed evolution. However, artificial compounds or environmental pollutants which are provoked by the conveyed evolution induce chemical (hormonal) imprinting in the developmental critical periods, which is transmitted to the progeny generations (transgenerational effect). This could cause evolutionary alterations without mutation.

Leila Mir Mojarabian

Full Text Available This research is a critical analysis on the place of human and his integration with religious issues, and the subject of disobedience and rebellion. In addition, topics such as reward, punishment, redemption and salvation of mankind in two great works of literature of the world, Masnavi by Mawlana and Paradise Lost by Milton have been comparatively discussed. Rumi's poetry and thought has been accepted by commons and special people in Iran and the world. Rumi is one of the few supreme poets in Persian language and the world. Generally, Milton has Known as the greatest English poet after Shakespeare, and his Paradise Lost as the greatest English fiction poem. This work is a the well-known epics of human-divine composed in live new languages, and comparing these two works even in one field of speech, indeed is the comparison of two thoughts, two nations, and two ancient cultures. The author attempts to examine the similarities and contrasts of the two poems of these two great poets on the subjects of human, God, and Satan and the world, to achieve the analytical and critical comparison of them in this context. In this paper the author tries to base the Paradise Lost of Milton and compare it with the ideas of Mawlana common to imagine man's first story and his disobedience, religious approaches, and finally the end presumed for mankind. In these two poems, contrast between "God" and "man" is derived from the fundamental relationship between "God" and "man". Milton while calls God, our Heavenly Father and refer to his role of creativity, entitles him as the dominant power, All mighty, the victorious winner, Glorious and Holy ruler, powerful king, and in one word, omnipotent. The Creator that all creatures are worshiping him, the omnipotent could be seen his capability remarks in everywhere, the unique structure of the universe beautiful is his own and the glorious ruler, sitting over the skies, sometimes invisible and sometimes visible, even

Effective selection of transgenic papaya plants with the PMI/Man selection system.

Science.gov (United States)

Zhu, Yun J; Agbayani, Ricelle; McCafferty, Heather; Albert, Henrik H; Moore, Paul H

2005-09-01

The selectable marker gene phospho-mannose isomerase (pmi), which encodes the enzyme phospho-mannose isomerase (PMI) to enable selection of transformed cell lines on media containing mannose (Man), was evaluated for genetic transformation of papaya (Carica papaya L.). We found that papaya embryogenic calli have little or no PMI activity and cannot utilize Man as a carbon source; however, when calli were transformed with a pmi gene, the PMI activity was greatly increased and they could utilize Man as efficiently as sucrose. Plants regenerated from selected callus lines also exhibited PMI activity but at a lower specific activity level. Our transformation efficiency with Man selection was higher than that reported using antibiotic selection or with a visual marker. For papaya, the PMI/Man selection system for producing transgenic plants is a highly efficient addition to previously published methods for selection and may facilitate the stacking of multiple transgenes of interest. Additionally, since the PMI/Man selection system does not involve antibiotic or herbicide resistance genes, its use might reduce environmental concerns about the potential flow of those genes into related plant populations.

Lack of Exposure in a First-in-Man Study Due to Aldehyde Oxidase Metabolism: Investigated by Use of 14C-microdose, Humanized Mice, Monkey Pharmacokinetics, and In Vitro Methods.

Inclusion of a microdose of 14 C-labeled drug in the first-in-man study of new investigational drugs and subsequent analysis by accelerator mass spectrometry has become an integrated part of drug development at Lundbeck. It has been found to be highly informative with regard to investigations of the routes and rates of excretion of the drug and the human metabolite profiles according to metabolites in safety testing guidance and also when additional metabolism-related issues needed to be addressed. In the first-in-man study with the NCE Lu AF09535, contrary to anticipated, surprisingly low exposure was observed when measuring the parent compound using conventional bioanalysis. Parallel accelerator mass spectrometry analysis revealed that the low exposure was almost exclusively attributable to extensive metabolism. The metabolism observed in humans was mediated via a human specific metabolic pathway, whereas an equivalent extent of metabolism was not observed in preclinical species. In vitro, incubation studies in human liver cytosol revealed involvement of aldehyde oxidase (AO) in the biotransformation of Lu AF09535. In vivo, substantially lower plasma exposure of Lu AF09535 was observed in chimeric mice with humanized livers compared with control animals. In addition, Lu AF09535 exhibited very low oral bioavailability in monkeys despite relatively low clearance after intravenous administration in contrast to the pharmacokinetics in rats and dogs, both showing low clearance and high bioavailability. The in vitro and in vivo methods applied were proved useful for identifying and evaluating AO-dependent metabolism. Different strategies to integrate these methods for prediction of in vivo human clearance of AO substrates were evaluated.

Agricultural measures to reduce radiation doses to man caused by severe nuclear accidents

International Nuclear Information System (INIS)

Dorp, F. van; Eleveld, R.; Frissel, M.J.

1981-01-01

Agricultural land and products may become contaminated after a severe nuclear accident. If radiation doses to man caused by the ingestion of contaminated agricultural products from such areas will be unacceptably high, measures to reduce this radiation dose will have to be taken. Radiation doses to man can be estimated by using models which describe quantitatively the transfer of radionuclides through the biosphere. The following processes and pathways are described in this study: accidental releases into atmospheric environments and subsequent nearby deposition; contamination of crops by direct deposition and the subsequent short term pathway (e.g. grass-cow-milk-man); contamination of soil and the subsequent long term pathway (e.g. soil-crop-man, soil-grass-cattle-milk/meat-man). Depending on the degree of contamination and on the estimated radiation doses to man, various measures are advised. (Auth.)

Man-machine supervision; Supervision homme-machine

2005-05-01

Today's complexity of systems where man is involved has led to the development of more and more sophisticated information processing systems where decision making has become more and more difficult. The operator task has moved from operation to supervision and the production tool has become indissociable from its numerical instrumentation and control system. The integration of more and more numerous and sophisticated control indicators in the control room does not necessary fulfill the expectations of the operation team. It is preferable to develop cooperative information systems which are real situation understanding aids. The stake is not the automation of operators' cognitive tasks but the supply of a reasoning help. One of the challenges of interactive information systems is the selection, organisation and dynamical display of information. The efficiency of the whole man-machine system depends on the communication interface efficiency. This article presents the principles and specificities of man-machine supervision systems: 1 - principle: operator's role in control room, operator and automation, monitoring and diagnosis, characteristics of useful models for supervision; 2 - qualitative reasoning: origin, trends, evolutions; 3 - causal reasoning: causality, causal graph representation, causal and diagnostic graph; 4 - multi-points of view reasoning: multi flow modeling method, Sagace method; 5 - approximate reasoning: the symbolic numerical interface, the multi-criteria decision; 6 - example of application: supervision in a spent-fuel reprocessing facility.

Heidegger: Sense-Nonsense Dualism of Man in Technology Dimensions

Directory of Open Access Journals (Sweden)

Nathalia Andrea Álvarez

2008-12-01

Full Text Available This article tries to analyze the ontological-existential compromise that man acquires when using new technologies, in the light of theHeideggerian’ proposal. This compromise means, on the one hand, theresponsibility of forgetting the self in technology, which immerses man in a non-sense; and on the other, the will to open himself to the recognition of the ways in which his “being-in-the-world” manifests. To this end, the perils of technological “instrumentalization” will be presented, based upon the Heideggerian explanation about the essence of technology. We will present the Heideggerian concepts of anxiety1 and nothingness concepts, with which we will try to conduct the postmodern man towards the encounter with his original sense.

Objective: To obtain concentrations of elements in Chinese current foods and their dietary intakes by adult man in order to provide a basis on intake parameters of Chinese Reference Man and make related hygienic evaluation. Methods: With mixed food sample method of total diet study, determination of element concentrations in constituent foods of diets for 4 areas with different diet types was carried out by using NAA, ICP-MS, ICP-AES, AAS and necessary QA measures, and estimation of their daily intakes and hygienic evaluation were also made. Results: The concentrations of 42 elements in 12 categories of foods, their intakes and hygienic evaluation for adult man were obtained. Conclusion: The data on element concentrations in Chinese foods and their dietary intakes were updated and widened. These data provided a new basis for developing the parameters of Chinese Reference Man and revealed some current hygienic problems.

Grimmer, G.

1992-01-01

The research project had the aim to develop a standard for measuring individual, inner stresses from polycyclic aromatic hydrocarbons (PAHs) at work. The employed method was by characterizing PAHs and metabolites of PAHs to be identified in urine with a view to developing a biological monitoring of professionally exposured persons. Using a number of PAHs relevant to work, the following questions were studied in cell culture systems and different animal-experimental models: Which metabolites are formed from the PAHs used in cell culture systems and the different animal-experimental models, and what are their ratios in percent? What percentage of a PAH is excreted by experimental animals in their urine and faeces on the first, second, and third day following different forms of application? What is the scale of the individual range of variation of PAH mass excretion? Are these results transferable to man? (orig.) [de

A manned Mars mission will involve a small crew and many complex tasks. The productivity of the crew and the entire mission will depend significantly on effective automation of these tasks and the ease with which the crew can interface with them. The technology to support a manned Mars mission is available today; however, evolving software and electronic technology are enabling many interesting possibilities for increasing productivity and safety while reducing life cycle cost. Some of these advanced technologies are identified.

A diffraction grating is a spatial filter causing sound waves or optical waves to reflect in directions determined by the frequency of the waves and the period of the grating. The classical grating equation is the governing principle that has successfully described the diffraction phenomena caused by gratings. However, in this work, we show experimental observation of the so-called sub-harmonic diffraction in acoustics that cannot be explained by the classical grating equation. Experiments indicate two physical phenomena causing the effect: internal scattering effects within the corrugation causing a phase shift and nonlinear acoustic effects generating new frequencies. This discovery expands our current understanding of the diffraction phenomenon, and it also makes it possible to better design spatial diffraction spectra, such as a rainbow effect in optics with a more complicated color spectrum than a traditional rainbow. The discovery reveals also a possibly new technique to study nonlinear acoustics by exploitation of the natural spatial filtering effect inherent to an acoustic diffraction grating.

Man-Robot Symbiosis: A Framework For Cooperative Intelligence And Control

Science.gov (United States)

Parker, Lynne E.; Pin, Francois G.

1988-10-01

The man-robot symbiosis concept has the fundamental objective of bridging the gap between fully human-controlled and fully autonomous systems to achieve true man-robot cooperative control and intelligence. Such a system would allow improved speed, accuracy, and efficiency of task execution, while retaining the man in the loop for innovative reasoning and decision-making. The symbiont would have capabilities for supervised and unsupervised learning, allowing an increase of expertise in a wide task domain. This paper describes a robotic system architecture facilitating the symbiotic integration of teleoperative and automated modes of task execution. The architecture reflects a unique blend of many disciplines of artificial intelligence into a working system, including job or mission planning, dynamic task allocation, man-robot communication, automated monitoring, and machine learning. These disciplines are embodied in five major components of the symbiotic framework: the Job Planner, the Dynamic Task Allocator, the Presenter/Interpreter, the Automated Monitor, and the Learning System.

A “chimera state” is a dynamical pattern that occurs in a network of coupled identical oscillators when the symmetry of the oscillator population is broken into synchronous and asynchronous parts. We report the experimental observation of chimera and cluster states in a network of four globally coupled chaotic opto-electronic oscillators. This is the minimal network that can support chimera states, and our study provides new insight into the fundamental mechanisms underlying their formation. We use a unified approach to determine the stability of all the observed partially synchronous patterns, highlighting the close relationship between chimera and cluster states as belonging to the broader phenomenon of partial synchronization. Our approach is general in terms of network size and connectivity. We also find that chimera states often appear in regions of multistability between global, cluster, and desynchronized states.

The Role of the Nuclear Envelope Protein MAN1 in Mesenchymal Stem Cell Differentiation.

Science.gov (United States)

Bermeo, Sandra; Al-Saedi, Ahmed; Kassem, Moustapha; Vidal, Christopher; Duque, Gustavo

2017-12-01

Mutations in MAN1, a protein of the nuclear envelope, cause bone phenotypes characterized by hyperostosis. The mechanism of this pro-osteogenic phenotype remains unknown. We increased and decreased MAN1 expression in mesenchymal stem cells (MSC) upon which standard osteogenic and adipogenic differentiation were performed. MAN1 knockdown increased osteogenesis and mineralization. In contrast, osteogenesis remained stable upon MAN1 overexpression. Regarding a mechanism, we found that low levels of MAN1 facilitated the nuclear accumulation of regulatory smads and smads-related complexes, with a concurrently high expression of nuclear β-Catenin. In addition, we found adipogenesis to be decreased in both conditions, although predominantly affected by MAN1 overexpression. Finally, lamin A, a protein of the nuclear envelope that regulates MSC differentiation, was unaffected by changes in MAN1. In conclusion, our studies demonstrated that lower levels of MAN1 in differentiating MSC are associated with higher osteogenesis and lower adipogenesis. High levels of MAN1 only affected adipogenesis. These effects could have an important role in the understanding of the role of the proteins of the nuclear envelope in bone formation. J. Cell.

Complement activated granulocytes can cause autologous tissue destruction in man

Directory of Open Access Journals (Sweden)

E. Löhde

1992-01-01

Full Text Available Activation of polymorphonuclear granulocytes (PMNs by C5a is thought to be important in the pathogenesis of multiple organ failure during sepsis and after trauma. In our experiment exposure of human PMNs to autologous zymosan activated plasma (ZAP leads to a rapid increase in chemiluminescence. Heating the ZAP at 56°C for 30 min did not alter the changes, while untreated plasma induced only baseline activity. The respiratory burst could be completely abolished by decomplementation and preincubation with rabbit antihuman C5a antibodies. Observation of human omentum using electron microscopy showed intravascular aggregation of PMNs, with capillary thrombosis and diapedesis of the cells through endothelial junctions 90 s after exposure to ZAP. PMNs caused disruption of connections between the mesothelial cells. After 4 min the mesothelium was completely destroyed, and connective tissue and fat cells exposed. Native plasma and minimum essential medium did not induce any morphological changes. These data support the concept that C5a activated PMNs can cause endothelial and mesothelial damage in man. Even though a causal relationship between anaphylatoxins and organ failure cannot be proved by these experiments C5a seems to be an important mediator in the pathogenesis of changes induced by severe sepsis and trauma in man.

From experimental zoology to big data: Observation and integration in the study of animal development.

Science.gov (United States)

Bolker, Jessica; Brauckmann, Sabine

2015-06-01

The founding of the Journal of Experimental Zoology in 1904 was inspired by a widespread turn toward experimental biology in the 19th century. The founding editors sought to promote experimental, laboratory-based approaches, particularly in developmental biology. This agenda raised key practical and epistemological questions about how and where to study development: Does the environment matter? How do we know that a cell or embryo isolated to facilitate observation reveals normal developmental processes? How can we integrate descriptive and experimental data? R.G. Harrison, the journal's first editor, grappled with these questions in justifying his use of cell culture to study neural patterning. Others confronted them in different contexts: for example, F.B. Sumner insisted on the primacy of fieldwork in his studies on adaptation, but also performed breeding experiments using wild-collected animals. The work of Harrison, Sumner, and other early contributors exemplified both the power of new techniques, and the meticulous explanation of practice and epistemology that was marshaled to promote experimental approaches. A century later, experimentation is widely viewed as the standard way to study development; yet at the same time, cutting-edge "big data" projects are essentially descriptive, closer to natural history than to the approaches championed by Harrison et al. Thus, the original questions about how and where we can best learn about development are still with us. Examining their history can inform current efforts to incorporate data from experiment and description, lab and field, and a broad range of organisms and disciplines, into an integrated understanding of animal development. © 2015 Wiley Periodicals, Inc.

Kuperman, I.

1978-08-01

In recent years, man-rem expenditures at operating stations have come under close scrutiny in order to reduce operating personnel dosage. This increased awareness has led to concerted efforts to improve station design and to improve operating procedures to achieve lower man-rem expenditures. This paper is intended to highlight design improvements that have been made in the CANDU 600 MW(e) design and to show how these improvements will reduce man-rem expenditures. Other considerations, such as station decontaminations of the primary heat transport system and the fuelling machines and stricter chemistry control are presently available to help reduce man-rem consumption. Also, station management operating policy should emphasize man-rem awareness. (author)

Dose-response relations for dicentric yields in G0 lymphocytes of man and crab-eating monkey following acute and chronic γ-irradiations

International Nuclear Information System (INIS)

Takahashi, E.; Hirai, M.; Tobari, I.; Nakai, S.A.

1979-01-01

A comparison has been made of dicentric yields in G 0 lymphocytes between man and crab-eating monkey, Macaca fascicularis, after acute and chronic γ-irradiations. With acute irradiation (49.6 rad/min) there was no significant difference between them, but for the chronic irradiation (17.1 rad/h) a significant difference was observed between the species. When the dose-response relations were fitted to the linear-quadratic model (Y = αD + βD 2 ), the species-difference observed for chronic irradiation was almost entirely due to change in the value of β. In addition, after chronic irradiation the β-value for monkey was almost negligible, but that for man was significant. Post-irradiation incubation experiment showed that cells with dicentrics were partly eliminated during the course of chronic irradiation, because there were appreciable reductions of dicentric yields (ca. 25% for both man and monkey at 400 rad) together with mitotic indices (ca. 30% and 60% for man and monkey, respectively, at 400 rad). Accordingly, it would be reasonable to postulate that G 0 repair for dicentrics other than selection mechanism must play a major role in the effects of low dose rate. It can be further suggested that G 0 -repair capacity for chromosal damages leading to dicentrics may be different among different primate species. (Auth.)

Engineering the yeast Yarrowia lipolytica for the production of therapeutic proteins homogeneously glycosylated with Man8GlcNAc2 and Man5GlcNAc2

De Pourcq Karen

2012-05-01

Full Text Available Abstract Background Protein-based therapeutics represent the fastest growing class of compounds in the pharmaceutical industry. This has created an increasing demand for powerful expression systems. Yeast systems are widely used, convenient and cost-effective. Yarrowia lipolytica is a suitable host that is generally regarded as safe (GRAS. Yeasts, however, modify their glycoproteins with heterogeneous glycans containing mainly mannoses, which complicates downstream processing and often interferes with protein function in man. Our aim was to glyco-engineer Y. lipolytica to abolish the heterogeneous, yeast-specific glycosylation and to obtain homogeneous human high-mannose type glycosylation. Results We engineered Y. lipolytica to produce homogeneous human-type terminal-mannose glycosylated proteins, i.e. glycosylated with Man8GlcNAc2 or Man5GlcNAc2. First, we inactivated the yeast-specific Golgi α-1,6-mannosyltransferases YlOch1p and YlMnn9p; the former inactivation yielded a strain producing homogeneous Man8GlcNAc2 glycoproteins. We tested this strain by expressing glucocerebrosidase and found that the hypermannosylation-related heterogeneity was eliminated. Furthermore, detailed analysis of N-glycans showed that YlOch1p and YlMnn9p, despite some initial uncertainty about their function, are most likely the α-1,6-mannosyltransferases responsible for the addition of the first and second mannose residue, respectively, to the glycan backbone. Second, introduction of an ER-retained α-1,2-mannosidase yielded a strain producing proteins homogeneously glycosylated with Man5GlcNAc2. The use of the endogenous LIP2pre signal sequence and codon optimization greatly improved the efficiency of this enzyme. Conclusions We generated a Y. lipolytica expression platform for the production of heterologous glycoproteins that are homogenously glycosylated with either Man8GlcNAc2 or Man5GlcNAc2 N-glycans. This platform expands the utility of Y. lipolytica as a

Estimating Safety Effects of Green-Man Countdown Devices at Signalized Pedestrian Crosswalk Based on Cellular Automata

Directory of Open Access Journals (Sweden)

Chen Chai

2017-01-01

Full Text Available Safety effects of Green-Man Countdown Device (GMCD at signalized pedestrian crosswalks are evaluated. Pedestrian behavior at GMCD and non-GMCD crosswalks is observed and analyzed. A microsimulation model is developed based on field observations to estimate safety performance. Simulation outputs allow analysts to assess the impacts of GMCD at various conditions with different geometric layout, traffic and pedestrian volumes, and the green time. According to simulation results, it is found that the safety impact of GMCD is affected by traffic condition as well as different time duration within green-man signal phase. In general, GMCD increases average walking velocity, especially during the last few seconds. The installation of GMCD improves safety performance generally, especially at more crowded crossings. Conflict severity is increased during last 10 s after GMCD installation. Findings from this study suggest that the current practice, which is to install GMCD at more crowded crosswalks or near the school zone, is effective. Moreover, at crosswalks with GMCD, longer all red signal phase is suggested to improve pedestrian safety during intergreen period.

OMV man/system simulation integration: A preliminary analysis and recommendation

Science.gov (United States)

Rogers, Jon G.

1988-01-01

The Orbital Maneuvering Vehicle (OMV) presents a series of challenges to the human operator. Some are unique to the OMV system itself, and are largely due to remote control versus control from the cockpit. Other challenges are not necessarily unique to the OMV, but are characteristic of many man-machine space flight systems. All of these challenges affect the operator's ability to perform his portion of the mission, and could lead to human error which might jeopardize the vehicle, mission, or both. It is imperative to make every effort to design the control and displays to facilitate the operator's task. The experimental program should address the perceptual, mediational, and motor dimensions of operator performance. With this in mind, a literature review with relevant design considerations was initiated, and a comprehensive outline of control/display parameters were developed. Out of this, a series of questions not answered in the literature was derived which can be converted into experimental protocols for the simulation program. A major task of the aircraft pilot as well as the OMV operator is prediction. Certain display principles have proved to enhance the pilot's ability to predict. A brief examination of some of these principles in relationship to OMV may be useful.

Kant's answer to the question 'what is man?' and its implications for anthropology.

Science.gov (United States)

Cohen, Alix A

2008-12-01

This paper examines Kant's anthropological project and its relationship to his conception of 'man' in order to show that Kant's answer to the question 'what is man?' entails a decisive re-evaluation of traditional conceptions of human nature. I argue that Kant redirects the question 'what is man?' away from defining man in terms of what he is, and towards defining him in terms of what he does, in particular through the distinction between three levels of what I will call 'man's praxis': the levels of technicality, prudence, and morality. As soon as man is understood in terms of what he makes of himself rather than in terms of what he is, two crucial issues arise: what is the purpose of his making? And how can he reach this destination? My claim is that whilst the first question is answered by ethics and a doctrine of prudence, the second question is answered by anthropology. In this sense, anthropology plays the crucial role of identifying the worldly helps and hindrances to the realisation of man's purposes--and this is the reason why it should be understood as a 'pragmatic' discipline.

Changes in phosphatidylcholine fatty acid composition are associated with altered skeletal muscle insulin responsiveness in normal man.

The fatty acid composition of skeletal muscle cell membrane phospholipids (PLs) is known to influence insulin responsiveness in man. We have recently shown that the fatty acid composition of phosphatidylcholine (PC), and not phosphatidylethanolamine (PE), from skeletal muscle membranes is of particular importance in this relationship. Efforts to alter the PL fatty acid composition in animal models have demonstrated induction of insulin resistance. However, it has been more difficult to determine if changes in insulin sensitivity are associated with changes in the skeletal muscle membrane fatty acid composition of PL in man. Using nicotinic acid (NA), an agent known to induce insulin resistance in man, 9 normal subjects were studied before and after treatment for 1 month. Skeletal muscle membrane fatty acid composition of PC and PE from biopsies of vastus lateralis was correlated with insulin responsiveness using a 3-step hyperinsulinemic-euglycemic clamp. Treatment with NA was associated with a 25% increase in the half-maximal insulin concentration ([ED50] 52.0 +/- 7.5 to 64.6 +/- 9.0 microU/mL, P insulin sensitivity. Significant changes in the fatty acid composition of PC, but not PE, were also observed after NA administration. An increase in the percentage of 16:0 (21% +/- 0.3% to 21.7% +/- 0.4%, P insulin resistance with NA is associated with changes in the fatty acid composition of PC in man.

A new wide-angle endoscope for visible light observation on the Experimental Advanced Superconducting Tokamak (EAST) has been recently developed. The head section of the optical system is based on a mirror reflection design that is similar to the International Thermonuclear Experimental Reactor-like wide-angle observation diagnostic on the Joint European Torus. However, the optical system design has been simplified and improved. As a result, the global transmittance of the system is as high as 79.6% in the wavelength range from 380 to 780 nm, and the spatial resolution is <5 mm for the full depth of field (4000 mm). The optical system also has a large relative aperture (1:2.4) and can be applied in high-speed camera diagnostics. As an important diagnostic tool, the optical system has been installed on the HT-7 (Hefei Tokamak-7) for its final experimental campaign, and the experiments confirmed that it can be applied to the investigation of transient processes in plasma, such as ELMy eruptions in H-mode, on EAST

This report presents a proposal of referent collective dose (man-rem) values for occupational exposure related to operation of French pressurized water reactors. These values, permitting adequate choice of protection both at design and operation level, are dependent on the level of annual individual doses. The man-rem value, originating from annual individual doses less than 0.5 rem are estimated to 1 kf. The proposed value is 20 kf for annual individual exposures between 0.5 and 3 rem, and 90 kf for annual individual exposures between 3 and 5 rem. (author) [fr

Radiocaesium transfer to man from moose and roe deer in Sweden

International Nuclear Information System (INIS)

Johanson, Karl J.; Bergstroem, R.

1994-01-01

Studies of radiocaesium in the forest ecosystems in Sweden resulted in aggregated transfer factors quantified for the transfer of 137 Cs from soil to moose and roe deer. These aggregated transfer factors were 0.02 m 2 kg -1 for moose and 0.05 m 2 kg -1 for roe deer. There seems to be no decrease in the 137 Cs activity concentrations in moose harvested in our research area and therefore we suggest the use of the physical half-life of 137 Cs (30 years) as the effective ecological half-life. The time-integrated transfer of 137 Cs from the Chernobyl fall-out to man by moose in Sweden was calculated and found to be 115 GBq, corresponding to 1500 man Sv for moose. The time-integrated transfer by roe deer to man was estimated to be between 25-48 GBq, corresponding to 327-620 man Sv for roe deer. The annual transfer of 137 Cs to man by moose has varied between 2.0-2.7 GBq, corresponding to 27-34 man Sv. Depending on the group studied, the mean annual transfer of 137 Cs can be calculated to be from about 250 to 43'000 Bq. For example, the mean annual transfer of 137 Cs by moose to hunters and their families in Gaevle commune, the most affected commune in Sweden, was estimated to be about 26'000 Bq, corresponding to 0.34 mSv

A new tool for man/machine integration

International Nuclear Information System (INIS)

Sommer, W.C.

1981-01-01

A popular term within the nuclear power industry today, as a result of TMI, is man/machine interface. It has been determined that greater acknowledgement of this interface is necessary within the industry to integrate the design and operational aspects of a system. What is required is an operational tool that can be used early in the engineering stages of a project and passed on later in time to those who will be responsible to operate that particular system. This paper discusses one such fundamental operations tool that is applied to a process system, its display devices, and its operator actions in a methodical fashion to integrate the machine for man's understanding and proper use. This new tool, referred to as an Operational Schematic, is shown and described. Briefly, it unites, in one location, the important operational display devices with the system process devices. A man can now see the beginning and end of each information and control loop to better understand its function within the system. A method is presented whereby in designing for operability, the schematic is utilized in three phases. The method results in two basic documents, one describes ''what'' is to be operated and the other ''how'' it is to be operated. This integration concept has now considered the hardware spectrum from sensor-to-display and operated the display (on paper) to confirm its operability. Now that the design aspects are complete, the later-in-time operational aspects need to be addressed for the man using the process system. Training personnel in operating and testing the process system is as important as the original design. To accomplish these activities, documents are prepared to instruct personnel how to operate (and test) the system under a variety of circumstances

The PH-D proposal - A manned mission to PHOBOS and Deimos

Science.gov (United States)

Singer, S. F.

The rationale for a manned mission to the satellites of Mars is discussed. The view has been expressed that NASA must define a major program to follow the Shuttle and to utilize it. However, such a program could not be initiated and proceed without public support, and to obtain this support, public interest would have to be excited. It is shown that, of a number of possible targets for manned exploration in the solar system, Mars appears to be the only possible candidate. Attention is given to a comparison of three Mars missions, a Mars 1984 mission, a manned landing on Mars surface, a manned landing on Phobos and Deimos (Ph-D project), putting men in Mars orbit, the capabilities of the Ph-D mission, a description of the spacecraft, a Ph-D project operations plan, and aspects of timing, technology, and costs.

Abstraction of man-made shapes

Man-made objects are ubiquitous in the real world and in virtual environments. While such objects can be very detailed, capturing every small feature, they are often identified and characterized by a small set of defining curves. Compact, abstracted shape descriptions based on such curves are often visually more appealing than the original models, which can appear to be visually cluttered. We introduce a novel algorithm for abstracting three-dimensional geometric models using characteristic curves or contours as building blocks for the abstraction. Our method robustly handles models with poor connectivity, including the extreme cases of polygon soups, common in models of man-made objects taken from online repositories. In our algorithm, we use a two-step procedure that first approximates the input model using a manifold, closed envelope surface and then extracts from it a hierarchical abstraction curve network along with suitable normal information. The constructed curve networks form a compact, yet powerful, representation for the input shapes, retaining their key shape characteristics while discarding minor details and irregularities. © 2009 ACM.

Marie Curie was awarded the Nobel Prize in chemistry 1911. During the preceding year a rumour had circulated in Stockholm that she had had an affaire with one of her assistants. She received a letter, in which she was told that there had been strong opposition to her election not on scientific but moral grounds, and that she should not go to Stockholm, because nobody could forsee what reactions her appearance at the prize ceremony could evoke. Emil Kleen, a man of violent temper and radical opinions, reacted strongly to these rumours. He wrote a paper, with a violent attack on Gustaf Retzius, previous professor of Histology at Karolinska Institutet. Rightly or wrongly he suspected him to be the author of the infamous letter. Retzius is described as a dilletant in scientific matters, as a "sexual hyena" and a garroulus old man. This portrait of Retzius is of course most unfair, but the portrait of Emil Kleen by the famous swedish artist Bruno Liljefors is a masterpiece and one of the most valuable of the Swedish Medical Association.

Natural and man-made terrestrial electromagnetic noise: an outlook

Full Text Available The terrestrial environment is continuously exposed to electromagnetic radiations which set up a «background» electromagnetic noise. Within the Non Ionizing Radiation band (NIR, i.e. for frequencies lower than 300 GHz, this background can have a natural or an artificial origin. Natural origins of electromagnetic radiations are generally atmospheric or cosmic while artificial origins are technological applications, power transmission, communications, etc. This paper briefly describes the natural and man-made electromagnetic noise in the NIR band. Natural noise comes from a large variety of sources involving different physical phenomena and covering a wide range of frequencies and showing various propagation characteristics with an extremely broad range of power levels. Due to technological growth man-made electromagnetic noise is nowadays superimposed on natural noise almost everywhere on Earth. In the last decades man-made noise has increased dramatically over and above the natural noise in residential and business areas. This increase has led some scientists to consider possible negative effects of electromagnetic waves on human life and living systems in general. Accurate measurements of natural and man-made electromagnetic noise are necessary to understand the relative power levels in the different bands and their influence on life.

Full Text Available Warship Man-Machine-Environment System Engineering (MMESE is an integral part of the overall design, and its design principles were proposed according to safety, efficiency, comfort and pleasure. The typical characteristics of MMESE are summarized. The operating environment is extremely terrible on long voyages. High level collaboration is required due to the complex task system and large manpower demand. Owing to the dense computer interface information, the mental cognitive burden on the crew is heavy. The MMESE technology system is divided into four parts:man-machine coordinated, man-environment coordinated, the evaluation of man-machine-environment characteristics and the ergonomic simulation. Based on the MMESE development venation in this paper, the overseas and domestic research statuses are expounded. Interactive optimization can be realized according to the following aspects:researching the basic human characteristics of the crew, applying this to the warship's overall design, and formulating relevant ergonomic standards and norms. Next, Human System Integration (HSI professional engineering was introduced comprehensively into the marines in order to achieve an optimal system. On this basis, we completed the future development trend analysis. All these studies and results have some reference meaning for guiding the integrated optimization of warships as a whole, downsizing the manpower and improving efficiency.

Experimental observations on electrorefining spent nuclear fuel in molten LiCl-KCl/liquid cadmium system

International Nuclear Information System (INIS)

Johnson, T. A.; Laug, D. V.; Li, S. X.; Sofu, T.

1999-01-01

Argonne National Laboratory (ANL) is currently performing a demonstration program for the Department of Energy (DOE) which processes spent nuclear fuel from the Experimental Breeder Reactor (EBR-II). One of the key steps in this demonstration program is electrorefining of the spent fuel in a molten LiCl-KCl/liquid cadmium system using a pilot scale electrorefiner (Mk-IV ER). This article summarizes experimental observations and engineering aspects for electrorefining spent fuel in the molten LiCl-KCl/liquid cadmium system. It was found that the liquid cadmium pool acted as an intermediate electrode during the electrorefining process in the ER. The cadmium level was gradually decreased due to its high vapor pressure and vaporization rate at the ER operational temperature. The low cadmium level caused the anode assembly momentarily to touch the ER vessel hardware, which generated a periodic current change at the salt/cathode interface and improved uranium recovery efficiency for the process. The primary current distributions calculated by numerical simulations were used in interpreting the experimental results

Almost a century ago, string states—complex bound states of magnetic excitations—were predicted to exist in one-dimensional quantum magnets. However, despite many theoretical studies, the experimental realization and identification of string states in a condensed-matter system have yet to be achieved. Here we use high-resolution terahertz spectroscopy to resolve string states in the antiferromagnetic Heisenberg-Ising chain SrCo2V2O8 in strong longitudinal magnetic fields. In the field-induced quantum-critical regime, we identify strings and fractional magnetic excitations that are accurately described by the Bethe ansatz. Close to quantum criticality, the string excitations govern the quantum spin dynamics, whereas the fractional excitations, which are dominant at low energies, reflect the antiferromagnetic quantum fluctuations. Today, Bethe’s result is important not only in the field of quantum magnetism but also more broadly, including in the study of cold atoms and in string theory; hence, we anticipate that our work will shed light on the study of complex many-body systems in general.

Bioethics against disappearance of a man a prism of general and criminal-law theory

Directory of Open Access Journals (Sweden)

Trajković Marko

2015-01-01

Full Text Available Bioethics, as a meeting point, engrossed with its fight against the disappearance of the man, both general and criminal-law theory. Actually, its 'care' for the man is an issue that comes before general and criminal-law theory. While the forms of disappearance of the man are very diverse and very often so refined that they cannon sometimes be recognized, the fight against the disappearance of the man must be open, clear and uncompromising. What is the role of law in this fight? The role imposed itself. Even if the law did not want to take part in the fight, it found itself in the middle of the battlefield because human life is protected from beginning to the end by legal norms that should emerge from the best writings of general and criminal-law theory. However, self-sufficiency of law and mere legal positivism are a true obstacle in this battle. This pressure and the lack of questionings are the first step on the road to disappearance of the man, because a man that asks questions is the man that exists. He and his boldness are a barrier to voluntarism. The lack of boldness of the man opens the gates to his disappearance. This boldness has not been taken away from him in the field of bioethics, which is neither secular nor religious, but rather unique as the man is unique.

The institutionalization of Jesus' charismatic authority: "Son of Man" as case study1

Directory of Open Access Journals (Sweden)

Yolanda Dreyer

2000-12-01

Full Text Available This article argues that Jesus used the expression "son of man" not in a titular way, but genetically, meaning "humankind". This use of "son of man" developed into a titular usage in which Jesus is identified with "Son of Man". The study shows that Jesus' use of the expression "son of man" should be understood in the context of the "little tradition" which was reinterpreted in terms of the "great tradition" in a titular way. It is argued that this transition from "litle tradition" to "great tradition"can be seen as "false attribution". After Jesus' death when his followers reorganized themselves into a cultic community, they gave Jesus the position "founder of the cult". They did this by making use of honorary titles. The use of the title "Son of Man" for Jesus is interpreted in terms of the social theory of the institutionalization of charismatic authority. The focus is on the title "Son of Man" as it appears in legal sayings or church rules, wisdom sayings and prophetic and apocalyptic sayings.

One of the concerns related to geologic CO2 sequestration is potential leakage of CO2 and its subsequent migration to shallow groundwater resources leading to geochemical impacts. Developing approaches to monitor CO2 migration in shallow aquifer and mitigate leakage impacts will require improving our understanding of gas phase formation and multi-phase flow subsequent to CO2 leakage in shallow aquifers. We are utilizing an integrated approach combining laboratory experiments and numerical simulations to characterize the multi-phase flow of CO2 in shallow aquifers. The laboratory experiments involve a series of highly controlled experiments in which CO2 dissolved water is injected in homogeneous and heterogeneous soil columns and tanks. The experimental results are used to study the effects of soil properties, temperature, pressure gradients and heterogeneities on gas formation and migration. We utilize the Finite Element Heat and Mass (FEHM) simulator (Zyvoloski et al, 2010) to numerically model the experimental results. The numerical models capture the physics of CO2 exsolution, multi-phase fluid flow as well as sand heterogeneity. Experimental observations of pressure, temperature and gas saturations are used to develop and constrain conceptual models for CO2 gas-phase formation and multi-phase CO2 flow in porous media. This talk will provide details of development of conceptual models based on experimental observation, development of numerical models for laboratory experiments and modelling results.

In the same way, comparisons have been made between cancers induced in man and in animals in well-defined conditions. In order to use the same experimental data for chemical carcinogens, the mechanisms of carcinogenesis should be the same, i.e. additivity of responses instead of synergy of effects, which requires the development of a new experimental method [fr

The strangest man. The hidden life of Paul Dirac

Farmelo, Graham

2016-01-01

The Strangest Man is the Costa Biography Award-winning account of Paul Dirac, the famous physicist sometimes called the British Einstein. He was one of the leading pioneers of the greatest revolution in twentieth-century science: quantum mechanics. The youngest theoretician ever to win the Nobel Prize for Physics, he was also pathologically reticent, strangely literal-minded and legendarily unable to communicate or empathize. Through his greatest period of productivity, his postcards home contained only remarks about the weather. Based on a previously undiscovered archive of family papers, Graham Farmelo celebrates Dirac's massive scientific achievement while drawing a compassionate portrait of his life and work. Farmelo shows a man who, while hopelessly socially inept, could manage to love and sustain close friendship. The Strangest Man is an extraordinary and moving human story, as well as a study of one of the most exciting times in scientific history.

Photonic crystals possessing multiple Weyl points and the experimental observation of robust surface states

Science.gov (United States)

Chen, Wen-Jie; Xiao, Meng; Chan, C. T.

2016-01-01

Weyl points, as monopoles of Berry curvature in momentum space, have captured much attention recently in various branches of physics. Realizing topological materials that exhibit such nodal points is challenging and indeed, Weyl points have been found experimentally in transition metal arsenide and phosphide and gyroid photonic crystal whose structure is complex. If realizing even the simplest type of single Weyl nodes with a topological charge of 1 is difficult, then making a real crystal carrying higher topological charges may seem more challenging. Here we design, and fabricate using planar fabrication technology, a photonic crystal possessing single Weyl points (including type-II nodes) and multiple Weyl points with topological charges of 2 and 3. We characterize this photonic crystal and find nontrivial 2D bulk band gaps for a fixed kz and the associated surface modes. The robustness of these surface states against kz-preserving scattering is experimentally observed for the first time. PMID:27703140

Ecology and man's environment

Energy Technology Data Exchange (ETDEWEB)

1975-01-01

A new and exciting discipline of human ecology is in the making. It has not, perhaps fortunately, found its bearings yet and remains to date overly dependent upon the limitations of sociology, biology, engineering and the sciences for its general theory, approaches, and philosophy. A new discipline with a world view and focussed on the human being and his habitat will hopefully emerge from a rich dialectic among scientists, humanists and policy makers educated and experienced in a variety of fields and committed to man's welfare. This new discipline and its practitioner must always be open to the revelations their knowledge will bring to man through the environmental processes. The implications of public policy, science and technology of industrial and post-industrial nations are all in need of considered re-examination by us all. Since their early application in these western societies we have witnessed the general downgrading of the world's environment. An ungrading in social priorities for the development of adequate housing, jobs, medical care and education which is almost always lower in rank than they should be is needed. The role of local groups, involving a well-informed and participating citizenship, in this process of changing priorities will always remain of prime importance, but no long-range goal in a rapidly-changing landscape is possible without broad national and local planning which contains ways and means of implementation.

1958 : Manning wants markets

International Nuclear Information System (INIS)

Anon.

2008-01-01

This article described the 2 opposing views in 1958 regarding how the big Montreal refinery market should be served. While the president of Imperial Oil expressed that Montreal refineries should not be forced to use domestic feedstocks, Alberta Premier Ernest Manning urged the Borden Commission to take immediate measures to expand the market for Canadian crude oil into Montreal. Manning argued that the dependence on Venezuelan crude in the Montreal refining market would pose a danger to the stability and development of the oil industry; loss of revenue for municipal, provincial and federal governments; and, an adverse effect on Canada's trade balance with the United States. The Premier suggested that these problems could be avoided by expanding the market for Canadian crude in Ontario and Quebec, in the U.S. Midwest, and in the Pacific Northwest. In 1958, the Canadian oil industry was divided on the Montreal market issue. Other key events in 1958 were listed. Waterton was characterized as Canada's biggest gas field, with reserves of 3 trillion cubic feet. A gas discovery at Berland River was considered the largest single-well exploration find in the world, flowing 27 million cubic feet per day on 1 drillstem. Two new refineries near Vancouver and Toronto were built to raise Canadian refining capacity to 813,000 barrels per day. 1 tab., 1 fig

Deep-sea disposal: Protecting fish and man

International Nuclear Information System (INIS)

Hagen, A.

1988-01-01

The definition of radioactive waste unsuitable for dumping at sea is based on the protection of man. See IAEA Safety Series No. 78. The development of criteria for assessing the impact on deep sea marine organisms at the population level has been attempted in a report recently published by the IAEA. See IAEA Technical Reports Series, No. 228 (1988). The report indicates that certain radionuclides may give rise to high dose rates to marine organisms if dumping is carried out with the assumptions of instantaneous release at the sea floor and dumping over long periods of time. In the report, a hypothetical dose rate to molluscs from zinc-65, which poses no significant harm to man, has the potential for giving high doses to bottom-dwelling molluscs

Automated reasoning in man-machine control systems

Stratton, R.C.; Lusk, E.L.

1983-01-01

This paper describes a project being undertaken at Argonne National Laboratory to demonstrate the usefulness of automated reasoning techniques in the implementation of a man-machine control system being designed at the EBR-II nuclear power plant. It is shown how automated reasoning influences the choice of optimal roles for both man and machine in the system control process, both for normal and off-normal operation. In addition, the requirements imposed by such a system for a rigorously formal specification of operating states, subsystem states, and transition procedures have a useful impact on the analysis phase. The definitions and rules are discussed for a prototype system which is physically simple yet illustrates some of the complexities inherent in real systems

1994-01-01

The spatial evolution of the radial profile of the magnetic field of a shear Alfven wave launched by a disk exciter with radius on the order of the electron skin depth has been measured. The waves are launched using wire mesh disk exciters of 4 mm and 8 mm radius into a helium plasma of density about 1.0x10 12 cm -3 and magnetic field 1.1 kG. The electron skin depth δ=c/ω pe is about 5 mm. The current channel associated with the shear Alfven wave is observed to spread with distance away from the exciter. The spreading follows a cone-like pattern whose angle is given by tan θ=k A δ, where k A is the Alfven wave number. The dependence of the magnetic profiles on wave frequency and disk size are presented. The effects of dissipation by electron--neutral collisions and Landau damping are observed. The observations are in excellent agreement with theoretical predictions [Morales et al., Phys. Plasmas 1, 3765 (1994)

Experimental observations of flow instabilities and rapid mixing of two dissimilar viscoelastic liquids

Directory of Open Access Journals (Sweden)

Hiong Yap Gan

2012-12-01

Full Text Available Viscoelastically induced flow instabilities, via a simple planar microchannel, were previously used to produce rapid mixing of two dissimilar polymeric liquids (i.e. at least a hundredfold different in shear viscosity even at a small Reynolds number. The unique advantage of this mixing technology is that viscoelastic liquids are readily found in chemical and biological samples like organic and polymeric liquids, blood and crowded proteins samples; their viscoelastic properties could be exploited. As such, an understanding of the underlying interactions will be important especially in rapid microfluidic mixing involving multiple-stream flow of complex (viscoelastic fluids in biological assays. Here, we use the same planar device to experimentally show that the elasticity ratio (i.e. the ratio of stored elastic energy to be relaxed between two liquids indeed plays a crucial role in the entire flow kinematics and the enhanced mixing. We demonstrate here that the polymer stretching dynamics generated in the upstream converging flow and the polymer relaxation events occurring in the downstream channel are not exclusively responsible for the transverse flow mixing, but the elasticity ratio is also equally important. The role of elasticity ratio for transverse flow instability and the associated enhanced mixing were illustrated based on experimental observations. A new parameter Deratio = Deside / Demain (i.e. the ratio of the Deborah number (De of the sidestream to the mainstream liquids is introduced to correlate the magnitude of energy discontinuity between the two liquids. A new Deratio-Demain operating space diagram was constructed to present the observation of the effects of both elasticity and energy discontinuity in a compact manner, and for a general classification of the states of flow development.

A nuclear-free land for Kennewick Man

Asmus, John

2011-06-01

flow will continue past Kennewick to threaten cities such as Portland with a Chernobyl-like tragedy. Consequently, a remediation program was initiated to drain the leaking tanks and ponds so that the toxic wastes could be buried elsewhere and/or transferred to more secure double-shell reservoirs. Unfortunately, hazardous substances adhere to pores and corrosion on the vessel walls after draining. This poses problems when disposing of refuse materials and hardware from the site. It has been experimentally determined that this hazardous surface contamination may be ejected by means of radiation ablation. It was concluded that this is most effectively accomplished with underwater flashlamp irradiation. In this manner the dislodged surface contamination is freed to float in the water and is then captured and concentrated by the filters of the fluid circulation systems. The final phase of the project was assistance in designing a Stonehenge-like monument to celebrate the cleanup of the Hanford Reservation and the removal of the radioactive threat to the final resting place of Kennewick Man ("The Ancient One").

Study of the man-caused destabilization consequences to the Semipalatinsk test site subsurface

2004-01-01

Conduction of underground nuclear explosions (UNE) at the territory of the Semipalatinsk Test Site (STS) has led to irreversible deformation of the geological environment. The carried out experimental researches on study of the UNE effect on the rocks massif allowed to ascertain the basic mechanisms of man-caused subsurface destabilization, which is a change in the physic-mechanical characteristics and filtering structure of the background medium, hydrogeodynamic and radiation situation. The consequences of the post-explosion deformations detected in the massif conjugate not only with the epicenter zone of UNE, but are also related to the structural boundaries of various range (to faults, lithologic contacts, boundaries of inhomogeneous media). The consequences were partially detected on the ground surface as well. (author)

Respiratory health effects of man-made vitreous (mineral) fibres.

1995-12-01

The group of man-made mineral or vitreous fibres (MMMFs or MMVFs) includes glass wool, rock wool, slag wool, glass filaments and microfibres, and refractory ceramic fibres (RCFs). Experimental observations have provided evidence that some types of MMVF are bioactive under certain conditions. The critical role of size parameters has been demonstrated in cellular and animal experiments, when intact fibres are in direct contact with the target cells. It is, however, difficult to extrapolate the results from these studies to humans since they bypass inhalation, deposition, clearance and translocation mechanisms. Inhalation studies are more realistic, but show differences between animal species regarding their sensibility to tumour induction by fibres. Fibre biopersistence is an important factor, as suggested by recent inhalation studies, which demonstrate positive results with RCF for fibrosis, lung tumours and mesothelioma. There is no firm evidence that exposure to glass-, rock- and slag wool is associated with lung fibrosis, pleural lesions, or nonspecific respiratory disease in humans. Exposure to RCF could enhance the effects of smoking in causing airways obstruction. An elevated standard mortality ratio for lung cancer has been demonstrated in cohorts of workers exposed to MMVF, especially in the early technological phase of mineral (rock slag) wool production. During that period, several carcinogenic agents (arsenic, asbestos, polycyclic aromatic hydrocarbons (PAH)) were also present at the workplace and quantitative data about smoking and fibre levels are lacking. It is not possible from these data to determine whether the risk of lung cancer is due to the MMVFs themselves. No increased risk of mesothelioma has been demonstrated in the cohorts of workers exposed to glass-, slag- or rock wool. There are in fact insufficient epidemiological data available concerning neoplastic diseases in RCF production workers because of the small size of the workforce and the

This article tries to analyze the ontological-existential compromise that man acquires when using new technologies, in the light of theHeideggerian’ proposal. This compromise means, on the one hand, theresponsibility of forgetting the self in technology, which immerses man in a non-sense; and on the other, the will to open himself to the recognition of the ways in which his “being-in-the-world” manifests. To this end, the perils of technological “instrumentalization” will be presented, based ...

Experimental measurements of microlayer formation and of the time history of microlayer thickness change have been obtained for nucleate boiling of water and ethanol. These detailed measurements were obtained using laser interometry combined with high-speed cinematography. The measurement technique is discussed in detail with emphasis on the difficulties encountered in interpretation of the fringe patterns. The measurements for water can be reasonably applied to the data of Gunther and Kreith, in which case it is concluded that microlayer evaporate alone cannot account for the increased heat transfer rates observed in highly subcooled nucleate boiling. It appears that microconvection must play at least an equal role

Renal artery denervation has recently emerged as a novel therapy for patients with resistant hypertension. Clinical results from renal sympathetic denervation support the safety and efficacy of this method over a period of 18 months. However, several limitations have been reported. Previous studies have shown that chemical denervation by vincristine is safe and effective in an experimental model. We describe the first-in-man application of chemical denervation with vincristine in a 74-year-old male patient with resistant arterial hypertension.

Methods for the determination of the man-Sievert monetary value

International Nuclear Information System (INIS)

Lombard, J.

1986-03-01

To estimate the efficiency of radiological protection systems we have to compare the cost involved in putting each system into operation (cost of protection) to the collective dose that can thus be avoided. This comparison is facilitated if a man-Sievert monetary value is available. The man-Sievert value can be estimated from various detriments than can be attributed to this unitary exposure: whether there are lethal or non-lethal somatic effects, genetic effects and psycho-social effects. ICRP recommends, in its publication 37, to break down the cost of radiological detriment Y into two parts. The first part, Y1=αS, corresponds to the somatic and genetic effects; the second part, Y2=β ΣN j f(Hj), corresponds to the relevant effects of psycho-social considerations. This breakdown leads to the definition of two man-Sievert value components: α, which reflects somatic and genetic detriments; and β, which reflects the psycho-social effects. Several different methods can be used to determine α and β. Here, we will analyse the following: the a priori evaluation based on the Value of Human Life (VHL) or the costs of repair (for non-lethal effects); the a priori evaluation based on the loss of life expectancy; the evaluation based on what an individual would agree to give up to reduce the risk associated to a man Sievert-dose; the evaluation based on the expenses effectively incurred in the past to reduce the risk associated to a man-Sievert dose [fr

Graham Greene and Cuba: Our man in Havana?

Directory of Open Access Journals (Sweden)

Peter Hulme

2008-12-01

Full Text Available [First paragraph] Graham Greene’s novel Our Man in Havana was published on October 6, 1958. Seven days later Greene arrived in Havana with Carol Reed to arrange for the filming of the script of the novel, on which they had both been working. Meanwhile, after his defeat of the summer offensive mounted by the Cuban dictator, Fulgencio Batista, in the mountains of eastern Cuba, just south of Bayamo, Fidel Castro had recently taken the military initiative: the day after Greene and Reed’s arrival on the island, Che Guevara reached Las Villas, moving westwards towards Havana. Six weeks later, on January 1, 1959, after Batista had fled the island, Castro and his Cuban Revolution took power. In April 1959 Greene and Reed were back in Havana with a film crew to film Our Man in Havana. The film was released in January 1960. A note at the beginning of the film says that it is “set before the recent revolution.” In terms of timing, Our Man in Havana could therefore hardly be more closely associated with the triumph of the Cuban Revolution. But is that association merely accidental, or does it involve any deeper implications? On the fiftieth anniversary of novel, film, and Revolution, that seems a question worth investigating, not with a view to turning Our Man in Havana into a serious political novel, but rather to exploring the complexities of the genre of comedy thriller and to bringing back into view some of the local contexts which might be less visible now than they were when the novel was published and the film released.

Definition And Realization Of The Priorities Features Of Public Prosecutor's Activity In The Sphere Of Rights And Freedoms Of The Man And Citizen Observance

Directory of Open Access Journals (Sweden)

Nadezhda A. Igonina

2015-03-01

Full Text Available In the present article the notion of "priorities of the prosecution" are defined, its value for the sphere of human rights and freedoms of man and citizen are stated. The classification of priorities, which is based on the provisions of the Russian Constitution and international law are stated. According to the authors, under the primary protection are the personal rights, which are derived from a natural person's status, inherent from birth. Next in order of priority are political rights, ensuring the full participation of citizens in the political life of the country, and finally - human rights in the socio-economic and cultural spheres, to guarantee the freedom of personal development and decent standards of living. Due to the authors` opinion, prosecutors in the allocation of the most important goals and objectives of its activities are guided by objective factors such as the analysis of the state of law, connection of the situation in this sphere of legal relations with the maintenance of stability and balance in the society, human rights functions, country's leadership and guidance of the General Prosecutor of the Russian Federation. The article shows, that the choice of priorities in the public prosecutor's activity, including the field of human rights and freedoms of man and citizen is a complex multi-faceted process, which affects the international situation, the internal processes, occurring in the country, including natural and man-made emergencies and a number of other factors. Authors identify issues that, in their opinion, should be addressed to improve the effectiveness of prosecutorial activities. That is the further development of the law about the Prosecutor's Office and the consolidation of its legal position, including constitutional status. Conclusions and suggestions are based on the authors' theoretical positions, made by the Russian jurists, as well as according their own empirical researches.

Hazards and maximum permissible doses of radiation for man

International Nuclear Information System (INIS)

Walinder, G.

1977-11-01

Maximum permissible dose levels are primarely based on risks for genetic damage and cancer. The reason for this is the observation that such late effects of radiation seem to arise even after doses that are to low to give rise to acute effects. In contrast to the tumour incidence found in irradiated human populations no genetic effects of radiation have been observed in man. This does not mean that genetic effects have not been induced but that it has been impossible to find an increase or to discern them among all the congenital defects, that can not be ascribed to the irradiation. As a consequence, the radiological risk estimation has been concentrated on the hazard of malignant diseases. Tumour risks are generally expressed as excess rates of incidence and mortality per million persons per rem. These figures are, however, not obtained from direct epidemiological observations but have been calculated from such data under the assumption of a linear relationship between effect and radiation dose. This formal extrapolation of observed data involves an uncertainty which, of course, is proportionately greater for the calculated effects in the millirem range. However, although the calculated tumour risks can not be said to be founded on direct scientific evidence, there are scientific reasons to believe that the figures derived from the formal extrapolations constitute an upper limit of possible ri02050

Fukui, Ken'ichi

This is a special lecture at the 30th anniversary of JICST. To develop science-and-te chnology-oriented society it is important to evaluate and select infinite information resources on science and technology, and to reorganize and apply them. This also relates to humanity. For the future, we have to establish scientific ethics that can exceed the expedience of science and technology. To be concrete, we have to create new industrial value that recovers and reclaims natural resources which men had wasted so far, and we have to establish a new technology to distribute maldistributed industrial benefits equally. And then, the selfcontrol of the human aiming at the harmony of nature and man will secure human liberty, and it will be done by the good function of man's brain.

Although there is a long history of consanguineous marriage in China, information on its prevalence is very limited. The Man (Qing) dynasty ruled China for over 250 years, but no consanguinity studies have been reported on this important population. The objective of the present investigation was to determine the present-day level of consanguineous marriage in the Man community, and to compare the data with existing consanguinity information on other Chinese populations. The study was conducted in a group of 11 rural Man communities in the north-eastern Chinese province of Liaoning. Household-based interviews were conducted by local staff on 513 couples, 418 of whom were Man with another 95 Man-Han inter-ethnic marriages. Basic pedigrees were constructed to determine the biological relationship between each set of spouses. Thirty of the 418 couples were in a consanguineous union, with a mean coefficient of inbreeding alpha = 0.0012. The small population sizes of the study may have contributed to the spatial variation in the patterns of inbreeding. Across generations there was a reduction in consanguineous marriages and an increase in inter-ethnic unions, which paralleled changes in civil marriage regulations.

Experimental Observation of the Aubry Transition in Two-Dimensional Colloidal Monolayers

The possibility to achieve entirely frictionless, i.e., superlubric, sliding between solids holds enormous potential for the operation of mechanical devices. At small length scales, where mechanical contacts are well defined, Aubry predicted a transition from a superlubric to a pinned state when the mechanical load is increased. Evidence for this intriguing Aubry transition (AT), which should occur in one dimension (1D) and at zero temperature, was recently obtained in few-atom chains. Here, we experimentally and theoretically demonstrate the occurrence of the AT in an extended two-dimensional (2D) system at room temperature using a colloidal monolayer on an optical lattice. Unlike the continuous nature of the AT in 1D, we observe a first-order transition in 2D leading to a coexistence regime of pinned and unpinned areas. Our data demonstrate that the original concept of Aubry not only survives in 2D but is relevant for the design of nanoscopic machines and devices at ambient temperature.

Reference man and woman more fully characterized: Variations on the basis of body size, age, sex, and race

International Nuclear Information System (INIS)

Ellis, K.J.

1990-01-01

Total body neutron activation analysis, prompt-gamma neutron activation analysis, and whole body counting have been used to determine the elemental composition of the human body. The total body elements measured were potassium, nitrogen, calcium, sodium, chlorine, and phosphorus. Total body water was also determined by the dilution principle using tritiated water. Observations were made in an adult US population that totaled 1374 and ranged in age from 20 to 90 yr. The dataset for the white population consisted of 175 males and 1134 females observations; for the black population, it consisted of 30 male and 35 female observations. The variation in the elemental composition of both males and females in any 5-yr age group was large and ranged up to 20% (SD). Age-, race-, sex-, and size-specific differences were evident. When equations were developed that predicted the elemental composition of the adult on the basis of age, weight, and height, the variation in the age groups was reduced approximately in half. Age-specific mean values for the 20- to 29-yr-old white population were also compared with values for the International Commission on Radiological Protection (ICRP)-23 Reference Man. The open-quotes averageclose quotes young adult male was larger than Reference Man; the in vivo data also indicated a larger skeletal mass, more lean tissues and body water, but lower body sodium. When in vivo prediction equations were used to adjust for size differences, good agreement was found between the expected values and those for Reference Man. The ICRP-23 does not contain elemental data for Reference Woman; therefore, the in vivo data in the present study provide the first estimates of body composition for Reference Woman

In this Letter we demonstrate the experimental observation of chaotic phase synchronization (CPS) in a periodically pump-modulated multimode microchip Nd:YVO{sub 4} laser. PS transition is displayed via the stroboscopic technique. We apply the recurrence probability and correlation probability of recurrence to estimate the degree of PS. The degree of PS is studied taking into account the modulation amplitude and modulation frequency. We also propose an experimental compatible numerical simulation to reflect the fact that the Arnold tongues are experimentally and numerically exhibited in the periodically pump-modulated multimode microchip Nd:YVO{sub 4} laser. -- Highlights: ► We show chaotic phase synchronization in a pump-modulated microchip Nd:YVO{sub 4} laser. ► Phase synchronization (PS) transition is displayed via the stroboscopic technique. ► The degree of PS is studied taking into account the modulation parameters. ► The Arnold tongues are experimentally and numerically exhibited in the laser.

Heavy metal pollution of man and environment - A historical perspective

International Nuclear Information System (INIS)

Jaworowski, Zbigniew

1989-01-01

'Normal' levels of heavy metals are disturbingly close to toxic levels. This may be a man-made or natural phenomenon. The man-made exposure to heavy metals started thousands of years ago. In some European populations in the past the lead level was orders of magnitude higher than now, where it is comparable with the prehistoric level. The former high contamination of human populations was due to intake of metals from immediate sources (utensils, drugs, etc) not to their dispersion in the environment. A dramatic decrease of lead level in man occurred recently, when the majority of the immediate sources disappeared, but when at the local (but not at the global) scale the environmental level of metals increased. The current flow of metals into the global atmosphere, similar to the pre-industrial flow, is still dominated by natural processes, such as biological methylization of metals. This leads to an enrichment of the airborne particles in metals up to several orders of magnitude above the crustal abundances. It is not the magnitude of emissions of metals into the global atmosphere that marks a new role of man in the biosphere, but the mass of anthropogenic mobilization of raw materials now reaching the geological dimensions.

A successful experimental observation of double-photon Compton scattering of γ rays using a single γ detector

International Nuclear Information System (INIS)

Saddi, M.B.; Sandhu, B.S.; Singh, B.

2006-01-01

The phenomenon of double-photon Compton scattering has been successfully observed using a single γ detector, a technique avoiding the use of the complicated slow-fast coincidence set-up used till now for observing this higher-order process. Here doubly differential collision cross-sections integrated over the directions of one of the two final photons, the direction of other one being kept fixed, are measured experimentally for 0.662 MeV incident γ photons. The energy spectra of the detected photons are observed as a long tail to the single-photon Compton line on the lower side of the full energy peak in the recorded scattered energy spectrum. The present results are in agreement with theory of this process

Regenerative environmental control and life support system (ECLSS) technologies are found by the present evaluation to have reached a degree of maturity that recommends their application to long duration manned missions. The missions for which regenerative ECLSSs are attractive in virtue of the need to avoid expendables and resupply requirements have been identified as that of the long duration LEO Space Station, long duration stays at GEO, a permanently manned lunar base (or colony), manned platforms located at the earth-moon libration points L4 or L5, a Mars mission, deep space exploration, and asteroid exploration. A comparison is made between nonregenerative and regenerative ECLSSs in the cases of 10 essential functions.

Experimental nitrogen dioxide poisoning in cattle

Energy Technology Data Exchange (ETDEWEB)

Cutlip, R C

1966-01-01

Experimental nitrogen dioxide inhalation has been reported to produce signs and lesions typical of field cases of bovine pulmonary adenomatosis (BPA) as described by Monlux et al, and Seaton. Similar lesions have been produced in mice and guinea pigs. These studies were conducted because of the similarities between silo-filler's disease of man, caused by nitrogen dioxide, and BPA. Since previous studies involved inadequate numbers of cattle, a more critical evaluation of the effects of nitrogen dioxide was needed. This project was designed to study the clinical and pathologic alterations induced in cattle by repeated exposure to nitrogen dioxide gas.

2003-01-01

In the framework of the SFS (Spent Fuel Stability) European project, a 3-day workshop has been organised to share ideas and get a common understanding in the issue of modelling the behaviour of the spent fuel under repository conditions. The ultimate goal is to set the experimental and theoretical basis for the development of the conceptual model for the fuel matrix alteration. The workshop has been organised with plenty of time to discuss the key issues both formally (presentations) and informally (meetings and discussions). Mos importantly, the presentations have been prepared in order to feed the construction and development of the conceptual model for the spent nuclear fuel matrix alteration, which is the ultimate goal of Work Package 4 of the SFS EU project. We do not want a standard Spent Fuel Workshop presentation, we really need your better experimental and theoretical ideas and realisation to accomplish the objective of this workshop. At the onset of the Workshop I will put for war our current thoughts on the development of a common conceptual model. Which are the main boundary conditions, what are the needed parameters and functionalities. Where are the main uncertainties, how can we narrow down these uncertainties. I expect the contributions from all the participants in order to feed back on these requirements and on the advancement towards a common conceptual model for SFS matrix alteration. (Author)

Photoperiodic differences in a forebrain nucleus involved in vocal plasticity: enkephalin immunoreactivity reveals volumetric variation in song nucleus lMAN but not NIf in male European starlings (Sturnus vulgaris).

Science.gov (United States)

Stevenson, Tyler J; Ball, Gregory F

2010-09-15

Seasonal variation in the volume of various song control nuclei in many passerine species remains one of the best examples of naturally occurring adult neuroplasticity among vertebrates. The lateral portion of the magnocellular nucleus of the anterior nidopallium (lMAN) is a song nucleus that is important for song learning and seems to be critical for inducing variability in the song structure that is later pruned via a feedback process to produce adult crystallized song. To date, lMAN has not been shown to exhibit seasonal changes in volume, probably because it is difficult to resolve the boundaries of lMAN when employing histological methods based on Nissl staining. Here, lMAN(core) volumes were examined in intact photostimulated (i.e., breeding), castrated photostimulated and photorefractory (i.e., nonbreeding) male starlings (Sturnus vulgaris) to investigate the degree of seasonal variation in brain morphology. We present data demonstrating that the volumes of the total MAN and lMAN(core) delineated by enkephalin immunoreactivity are greater in photostimulated male starlings as compared to photorefractory males. Moreover, two other regions associated with the song system that have not been investigated previously in the context of seasonal plasticity namely (i) the medial portion of MAN (mMAN), and (ii) the nucleus interfacialis (NIf) did not display significant volumetric variation. We propose that greater lMAN(core) volumes are associated with the increase in vocal plasticity that is generally observed prior to production of stereotyped song.

Clinical Impact Research - how to choose experimental or observational intervention study?

Science.gov (United States)

Malmivaara, Antti

2016-11-01

Interventions directed to individuals by health and social care systems should increase health and welfare of patients and customers. This paper aims to present and define a new concept Clinical Impact Research (CIR) and suggest which study design, either randomized controlled trial (RCT) (experimental) or benchmarking controlled trial (BCT) (observational) is recommendable and to consider the feasibility, validity, and generalizability issues in CIR. The new concept is based on a narrative review of the literature and on author's idea that in intervention studies, there is a need to cover comprehensively all the main impact categories and their respective outcomes. The considerations on how to choose the most appropriate study design (RCT or BCT) were based on previous methodological studies on RCTs and BCTs and on author's previous work on the concepts benchmarking controlled trial and system impact research (SIR). The CIR covers all studies aiming to assess the impact for health and welfare of any health (and integrated social) care or public health intervention directed to an individual. The impact categories are accessibility, quality, equality, effectiveness, safety, and efficiency. Impact is the main concept, and within each impact category, both generic- and context-specific outcome measures are needed. CIR uses RCTs and BCTs. CIR should be given a high priority in medical, health care, and health economic research. Clinicians and leaders at all levels of health care can exploit the evidence from CIR. Key messages The new concept of Clinical Impact Research (CIR) is defined as a research field aiming to assess what are the impacts of healthcare and public health interventions targeted to patients or individuals. The term impact refers to all effects caused by the interventions, with particular emphasis on accessibility, quality, equality, effectiveness, safety, and efficiency. CIR uses two study designs: randomized controlled trials (RCTs) (experimental

Man-machine interaction in Canadian nuclear power plants

International Nuclear Information System (INIS)

Olmstead, R.A.

1994-01-01

The design of man-machine interaction in the CANDU plants has evolved considerably over several generations of plants, from the first Douglas Point plant through to the next generation of plants represented by new designs like CANDU 3. In the early plants, the control room configuration was based on designers' projections of control interface requirements. With succeeding generations of designs, there has been an evolution towards a more systematic consideration of human strengths and weaknesses, increasing attention to formal requirements definition, and incorporation of a larger base of operational experience. This paper describes the design of the man-machine interaction for third generation CANDU-3 control rooms for improved operator reliability and reduced costs. (author). 13 refs., 3 figs

Radiation shield analysis for a manned Mars rover

Morley, N.J.; ElGenk, M.S.

1991-01-01

Radiation shielding for unmanned space missions has been extensively studied; however, designs of man-rated shields are minimal. Engle et al.'s analysis of a man-rated, multilayered shield composed of two and three cycles (a cycle consists of a tungsten and a lithium hydride layer) is the basis for the work reported in this paper. The authors present the results of a recent study of shield designs for a manned Mars rover powered by a 500-kW(thermal) nuclear reactor. A train-type rover vehicle was developed, which consists of four cars and is powered by an SP-100-type nuclear reactor heat source. The maximum permissible dose rate (MPD) from all sources is given by the National Council on Radiation Protection and Measurements as 500 mSv/yr (50 rem/yr) A 3-yr Mars mission (2-yr round trip and 1-yr stay) will deliver a 1-Sv natural radiation dose without a solar particle event, 450 mSv/yr in flight, and an additional 100 mSv on the planet surface. An anomalously large solar particle event could increase the natural radiation dose for unshielded astronauts on the Martian surface to 200 mSv. This limits the MPD to crew members from the nuclear reactor to 300 mSv

Man as a safety problem in technical systems

International Nuclear Information System (INIS)

Compes, P.C.; Wolff, H.A.

1980-01-01

Safety engineering derives its justification from the success achieved in maintaining and enlarging safety, more precisely, from activities aimed at avoiding or preventing damage caused by accidents. Man is not only affected by accidents but is also the cause of accidents, either directly or indirectly, and thus is to be regarded as the actual cause or preventer of accidents. The Second International Summer Symposium of the Society for Safety Engineering (GfS) which was held at Duesseldorf in 1980 brought into focus this aspect and the importance to be attached to the individual man and the whole mankind in the field of accident prevention. 'Man as a safety problem in technical systems' - a great and weighty field of problems, the large extent of which and the complex content of which was to be discussed by the programme with its many different contributions, on the one hand by presenting an outline as completely as possible, and on the other hand by finding further-reaching solutions for at least some problems. This was the purpose of the dialogues held between theory and practice on the one hand, and between safety engineering and, in this case, the human sciences on the other hand. (orig./RW) [de

Data assimilation within the Advanced Circulation (ADCIRC) modeling framework for the estimation of Manning's friction coefficient

KAUST Repository

Mayo, Talea

2014-04-01

Coastal ocean models play a major role in forecasting coastal inundation due to extreme events such as hurricanes and tsunamis. Additionally, they are used to model tides and currents under more moderate conditions. The models numerically solve the shallow water equations, which describe conservation of mass and momentum for processes with large horizontal length scales relative to the vertical length scales. The bottom stress terms that arise in the momentum equations can be defined through the Manning\\'s n formulation, utilizing the Manning\\'s n coefficient. The Manning\\'s n coefficient is an empirically derived, spatially varying parameter, and depends on many factors such as the bottom surface roughness. It is critical to the accuracy of coastal ocean models, however, the coefficient is often unknown or highly uncertain. In this work we reformulate a statistical data assimilation method generally used in the estimation of model state variables to estimate this model parameter. We show that low-dimensional representations of Manning\\'s n coefficients can be recovered by assimilating water elevation data. This is a promising approach to parameter estimation in coastal ocean modeling. © 2014 Elsevier Ltd.

Conformation of glycomimetics in the free and protein-bound state: structural and binding features of the C-glycosyl analogue of the core trisaccharide alpha-D-Man-(1 --> 3)-[alpha-D-Man-(1 --> 6)]-D-Man.

Science.gov (United States)

Mikkelsen, Lise Munch; Hernáiz, María José; Martín-Pastor, M; Skrydstrup, Troels; Jiménez-Barbero, Jesús

2002-12-18

The conformational properties of the C-glycosyl analogue of the core trisaccharide alpha-D-Man-(1 --> 3)-[alpha-D-Man-(1 --> 6)]-D-Man in solution have been carefully analyzed by a combination of NMR spectroscopy and time-averaged restrained molecular dynamics. It has been found that both the alpha-1,3- and the alpha-1,6-glycosidic linkages show a major conformational averaging. Unusual Phi ca. 60 degrees orientations for both Phi torsion angles are found. Moreover, a major conformational distinction between the natural compound and the glycomimetic affects to the behavior of the omega(16) torsion angle around the alpha-1 --> 6-linkage. Despite this increased flexibility, the C-glycosyl analogue is recognized by three mannose binding lectins, as shown by NMR (line broadening, TR-NOE, and STD) and surface plasmon resonance (SPR) methods. Moreover, a process of conformational selection takes place, so that these lectins probably bind the glycomimetic similarly to the way they recognize the natural analogue. Depending upon the architecture and extension of the binding site of the lectin, loss or gain of binding affinity with respect to the natural analogue is found.

Cognitive task analysis of nuclear power plant operators for man-machine interface design

Itoh, J.I.; Yoshimura, S.; Ohtsuka, T.

1990-01-01

This paper aims to ascertain and further develop design guidelines for a man-machine interface compatible with plant operators' problem solving strategies. As the framework for this study, operator's information processing activities were modeled, based on J. Rasmussen's framework for cognitive task analysis. Two experiments were carried out. One was an experiment aimed at gaining an understanding of internal mechanisms involved in mistakes and slips which occurred in operators' responses to incidents and accidents. As a result of fifteen cases of operator performance analysis, sixty one human errors were identified. Further analysis of the errors showed that frequently occurring error mechanisms were absent-mindedness, lack of recognition of patterns in diagnosis and failed procedure formulation due to memory lapses. The other kind of experiment was carried out to identify the envelope of trajectories for the operator's search in the problem space consisting of the two dimensions of means-ends and whole-part relations while dealing with transients. Two cases of experimental sessions were conducted with the thinking-aloud method. From analyses based on verbal protocols, trajectories of operator's search were derived, covering from the whole plant level through the component level in the whole-part dimension and covering from the functional purpose level through the physical form level in the means-ends dimension. The findings obtained from these analyses serve as a basis for developing design guidelines for man-machine interfaces in control rooms of nuclear power plants

A complex nozzle concept, which fuses multiple canonical flows together, has been experimentally investigated via pressure, schlieren and PIV in the anechoic chamber at Syracuse University. Motivated by future engine designs of high-performance aircraft, the rectangular, supersonic jet under investigation has a single plane of symmetry, an additional shear layer (referred to as a wall jet) and an aft deck representative of airframe integration. Operating near a Reynolds number of 3 ×106 , the nozzle architecture creates an intricate flow field comprised of high turbulence levels, shocks, shear & boundary layers, and powerful corner vortices. Current data suggest that the wall jet, which is an order of magnitude less energetic than the core, has significant control authority over the acoustic power through some non-linear process. As sound is a direct product of turbulence, experimental and analytical efforts further explore this interesting phenomenon associated with the turbulent flow.

At 2011 we have described the imbalance of water in Nature as the system [1]. At 2012 we have described water and carbon and the glaciers [2], [3] as creators of the imbalance of Nature. Now we are describing some man-made creators of the imbalance of Nature. The photosynthesis is a powerful creator of the imbalance of Nature. The photosynthesis significantly increases the complexity of the structures and reduces the entropy. Earth's hydrosphere contains water less than it was flowed via photosynthesis. This is an example of the imbalance of involving when the return of water has delayed because water is involved into the processes of life and other processes. People widely use photosynthesis and create not only an additional man-made imbalance of water in Nature, but also the man-made changing the albedo, and a lot of other important parameters of the planet of Earth. All of these processes are significantly imbalanced. The fossil hydrocarbons have accumulated during millions of years, but now are burned. This is an example of the imbalance delay by time. The man-made burning of the hydrocarbons is creating the imbalances of impact or explosive type, because of the burning processes is in millions of times faster than the accumulation processes. Please pay attention to the imbalance of redeployment by places. For example, oil and gas are extracted in one places, and burned in others. During combustion is standing out not only water, but energy, and other components. The temperature in the centers of big cities is always higher and there is dominating the rising air. It pollutes the environment, changes circulations, create greenhouse effect, etc. Other examples of the imbalance of relocation are shown in the production and consumption of food. The irrigation systems transfer water from one place to another. This transfer of water creates a lot of imbalances in change climate, ecosystems, etc in places where water was took and where the water was brought. Usually

Climate and man in the Arctic

International Nuclear Information System (INIS)

1997-01-01

The ever-changing climate shapes the Arctic landscape, influences life conditions for plants and animals and alters the availability of the living resources that play such and important part in the economy of Arctic peoples. It is essential that we try to understand the nature of climatic change and its effects on man and his environment. Only this way can we hope to be able to predict future changes that may have great consequences for the well-being of northern residents. In recent years many research projects have been addressing the subject and important advances have been made. At the same time it has become increasingly evident that the complexity of the whole issue calls for an integration of scientific approaches and for interdisciplinary collaboration. The seminar 'Climate and Man in the Arctic' provided an opportunity both to highlight important areas of climate related research and to discuss more general aspects of arctic research. Eight papers presented at the seminar are published in this volume. (au) 22 refs

Man-machine communication in reactor control using AI methods

1987-01-01

In the last years the interest in process control has expecially focused on problems of man-machine communication. It depends on its great importance to process performance and user acceptance. Advanced computerized operator aids, e.g. in nuclear power plants, are as well as their man-machine interface. In the Central Institute for Nuclear Research in Rossendorf a computerized operator support system for nuclear power plants is designed, which is involved in a decentralized process automation system. A similar but simpler system, the Hierarchical Informational System (HIS) at the Rossendorf Research Reactor, works with a computer controlled man-machine interface, based on menu. In the special case of the disturbance analysis program SAAP-2, which is included in the HIS, the limits of menu techniques are obviously. Therefore it seems to be necessary and with extended hard- and software possible to realize an user controlled natural language interface using Artificial Intelligence (AI) methods. The draft of such a system is described. It should be able to learn during a teaching phase all phrases and their meanings. The system will work on the basis of a self-organizing, associative data structure. It is used to recognize a great amount of words which are used in language analysis. Error recognition and, if possible, correction is done by means of a distance function in the word set. Language analysis should be carried out with a simplified word class controlled functional analysis. With this interface it is supposed to get experience in intelligent man-machine communication to enhance operational safety in future. (author)

Patients with Type I congenital disorders of glycosylation (CDG-I) make incomplete lipid-linked oligosaccharides (LLO). These glycans are poorly transferred to proteins resulting in unoccupied glycosylation sequons. Mutations in phosphomannomutase (PMM2) cause CDG-Ia by reducing the activity of PMM, which converts mannose (Man)-6-P to Man-1-P before formation of GDP-Man. These patients have reduced Man-1-P and GDP-Man. To replenish intracellular Man-1-P pools in CDG-Ia cells, we synthesized two hydrophobic, membrane permeable acylated versions of Man-1-P and determined their ability to normalize LLO size and N-glycosylation in CDG-Ia fibroblasts. Both compounds, compound I (diacetoxymethyl 2,3,4,6-tetra-O-acetyl-alpha-D-mannopyranosyl phosphate) (C-I) and compound II (diacetoxymethyl 2,3,4,6-tetra-O-ethyloxycarbonyl-alpha-D-mannopyranosyl phosphate) (C-II), contain two acetoxymethyl (CH2OAc) groups O-linked to phosphorous. C-I contains acetyl esters and C-II contains ethylcarbonate (CO2Et) esters on the Man residue. Both C-I and C-II normalized truncated LLO, but C-II was about 2-fold more efficient than C-I. C-II replenished the GDP-Man pool in CDG-Ia cells and was more efficiently incorporated into glycoproteins than exogenous Man at low concentrations (25-75 mM). In a glycosylation assay of DNaseI in CDG-Ia cells, C-II restored glycosylation to control cell levels. C-II also corrected impaired LLO biosynthesis in cells from a Dolichol (Dol)-P-Man deficient patient (CDG-Ie) and partially corrected LLO in cells from an ALG12 mannosyltransferase-deficient patient (CDG-Ig), whereas cells from an ALG3-deficient patient (CDG-Id) and from an MPDU1-deficient patient (CDG-If) were not corrected. These results validate the general concept of using pro-Man-1-P substrates as potential therapeutics for CDG-I patients.

Ergonomic analysis of work in energy control plants: factors to be observed

International Nuclear Information System (INIS)

Rivas, R.

1987-01-01

To make evident the incidence of the technology modification due to the increasing automation of energy control plants on man, whose activity is limited to observation and control, with low working metabolism and high attention and concentration. The methodology is fundamentally based on the individual analysis of the factors affecting man. The following will be considered: a) load volume: the load volume generated by the above mentioned activity depends on the observation period, the number of indicators to be observed and the frequency of control activities; b) active participation: the lack of active participation due to a motionless task requires a constant yield disposition to develop an unusual activity; c) monotonous activity: the load is produced by maintaining a suitable physic-mental state through a volition effort; d) change of disposition: this component, which is not willingly admitted, changes the mechanism of compared functions during the day, following a biological law that depends from the hour; e) environment influence: the unfavorable physical influences, like climate, lack of light, noise, etc. also affect man. The analysis of mental load is specially important due to its influence on the performance, the accident risk and the safety of the system to be controlled. (Author)

The institutionalization of Jesus' charismatic authority: "Son of Man" as case study¹

OpenAIRE

Yolanda Dreyer

2000-01-01

This article argues that Jesus used the expression "son of man" not in a titular way, but genetically, meaning "humankind". This use of "son of man" developed into a titular usage in which Jesus is identified with "Son of Man". The study shows that Jesus' use of the expression "son of man" should be understood in the context of the "little tradition" which was reinterpreted in terms of the "great tradition" in a titular way. It is argued that this transition from "litle tradition" to "great t...

Meiotic behaviour and spermatogenesis in male mice heterozygous for translocation types also occurring in man

Nijhoff, J.H.

1981-01-01

In this thesis a start was made with meiotic observations of mouse translocation types - a Robertsonian translocation and a translocation between a metacentric and an acrocentric chromosome - which also occur in man. As an exogeneous factor of possible influence, the meiotic effects of two types of radiation (fission neutrons and X-rays) administered at relatively low doses 2 and 3 hours before prometaphase-metaphase II (probably during metaphase-anaphase I), were determined in Rb4Bnr/+-males.

Enoximone, 1,3-dihydro-4-methyl-5-[4-(methylthio)benzoyl]-2H-imidazol-2-one is a new cardiotonic agent which is currently undergoing clinical evaluation in patients with congestive heart failure. Biotransformation of enoximone was studied in man, rat, monkey and dog by means of 14 C-labelled material, HPLC and GC/MS techniques. Metabolic conversions were qualitatively similar in all species. The parent compound was found to be extensively metabolized. Generally less than 1% of the dose was recovered as enoximone in urine. The sulfoxide was the major metabolite in all species, accounting for over 90% of the dose in the urine of the monkey and greater than 75% in man and the rat. The sulfone was present in trace quantities, except in the rats, where it accounted for 5-8% of the dose. A glycine conjugate of 4-methylthiobenzoic acid was also identified as a urinary metabolite; and the dog seems to favor this pathway more than the other 3 species; as it accounted for over 30% of the dose. The two stereoisomers of synthetic sulfoxide were separated by HPLC, and examination of urine from patients receiving enoximone therapy suggested that the metabolic conversion of enoximone to sulfoxide was stereospecific, as only one isomeric peak was observed in the HPLC system

2010-01-01

Abort trajectory is a passage that ensures the astronauts to return safely to the earth when an emergency occurs. Firstly,the essential elements of mission abort are analyzed entirely based on summarizing the existing studies. Then,abort trajectory requirement and rational selection for different flight phases of typical manned lunar mission are discussed specifically. Considering a trade-off between the two primary constrains of an abort,the return time of flight and energy requirement,a general optimizing method for mission abort is proposed. Finally,some suggestions are given for China’s future manned lunar landing mission.

2010-07-01

The development of a completely new series of gas turbines requires significant capital, resources and know-how. MAN Diesel and Turbo strategically decided to create a small gas turbine in the 6 MW-class. The construction of the Gas Turbine has been on the basis of opportunities in current and future markets and the positioning of the competition, this has determined the characteristics and technical parameters which have been optimised in the 6 MW design. The construction uses extremely high precision engineering so that the assembly of sub-components to modules is a smooth flowing process and can guarantee the high standards both quality and performance which MAN Diesel and Turbo are operating to. The individual components must be tested and thoroughly validated many months before actual assembly of the first machine. These include in particular the compressor of the gas turbine and the combustion chamber. The combustion system required special attention, since the emissions are strongly focused to satisfy stringent environmental requirements. The planned tests are a prerequisite for the construction of such a prototype and must be successfully completed before the Gas Turbine will be accepted into service. (orig.)

The survival rate of septic patients mainly depends on a rapid and reliable diagnosis. A rapid, broad range, specific and sensitive quantitative diagnostic test is the urgent need. Thus, we developed a TaqMan-Based Multiplex real-time PCR assays to identify bloodstream pathogens within a few hours. Primers and TaqMan probes were designed to be complementary to conserved regions in the 16S rDNA gene of different kinds of bacteria. To evaluate accurately, sensitively, and specifically, the known bacteria samples (Standard strains, whole blood samples) are determined by TaqMan-Based Multiplex real-time PCR. In addition, 30 blood samples taken from patients with clinical symptoms of sepsis were tested by TaqMan-Based Multiplex real-time PCR and blood culture. The mean frequency of positive for Multiplex real-time PCR was 96% at a concentration of 100 CFU/mL, and it was 100% at a concentration greater than 1000 CFU/mL. All the known blood samples and Standard strains were detected positively by TaqMan-Based Multiplex PCR, no PCR products were detected when DNAs from other bacterium were used in the multiplex assay. Among the 30 patients with clinical symptoms of sepsis, 18 patients were confirmed positive by Multiplex real-time PCR and seven patients were confirmed positive by blood culture. TaqMan-Based Multiplex real-time PCR assay with highly sensitivity, specificity and broad detection range, is a rapid and accurate method in the detection of bacterial pathogens of sepsis and should have a promising usage in the diagnosis of sepsis. © 2017 Wiley Periodicals, Inc.

Full Text Available A novel mechanical design of the broken rope protection device is proposed to enhance the safety performances of the overhead manned equipment. According to the operating characteristics and functional requirements of the overhead manned equipment, a three-dimensional mechanical model of the broken rope protection device was redesigned. Based on the known parameters of the mechanical model, the stress and strength of the main components are readjusted using the statics characteristics of finite element analysis. To ensure the reliability of the control system of the broken rope protection device, the process of people’s falling, the response performance of the tension sensor, and the signal extraction of the broken rope are analyzed under different loading and unloading speeds. The working principle of the broken rope protection device is expounded in detail. The experimental results showed that better effect is obtained by the new broken rope protection device, which is characterized by good durability, low investment, and high reliability.

Building manned lunar base is one of the core aims of human lunar exploration project, which is also an important way to carry out the exploitation and utilization of lunar in situ resources. The most important part of manned lunar base is the design and construction of living habitation and many factors should be considered including science objective and site selection. Through investigating and research, the scientific goals of manned lunar base should be status and characteristics ascertainment of lunar available in situ resources, then developing necessary scientific experiments and utilization of lunar in situ resources by using special environment conditions of lunar surface. The site selection strategy of manned lunar base should rely on scientific goals according to special lunar surface environment and engineering capacity constraints, meanwhile, consulting the landing sites of foreign unmanned and manned lunar exploration, and choosing different typical regions of lunar surface and analyzing the landform and physiognomy, reachability, thermal environment, sunlight condition, micro meteoroids protection and utilization of in situ resources, after these steps, a logical lunar living habitation site should be confirmed. This paper brings out and compares three kinds of configurations with fabricating processes of manned lunar base, including rigid module, flexible and construction module manned lunar base. 1.The rigid habitation module is usually made by metal materials. The design and fabrication may consult the experience of space station, hence with mature technique. Because this configuration cannot be folded or deployed, which not only afford limit working and living room for astronauts, but also needs repetitious cargo transit between earth and moon for lunar base extending. 2. The flexible module habitation can be folded in fairing while launching. When deploying on moon, the configuration can be inflatable or mechanically-deployed, which means under

Quantification of human error and common-mode failures in man-machine systems

International Nuclear Information System (INIS)

Lisboa, J.J.

1988-01-01

Quantification of human performance, particularly the determination of human error, is essential for realistic assessment of overall system performance of man-machine systems. This paper presents an analysis of human errors in nuclear power plant systems when measured against common-mode failures (CMF). Human errors evaluated are improper testing, inadequate maintenance strategy, and miscalibration. The methodology presented in the paper represents a positive contribution to power plant systems availability by identifying sources of common-mode failure when operational functions are involved. It is also applicable to other complex systems such as chemical plants, aircraft and motor industries; in fact, any large man-created, man-machine system could be included

Dynamical explanation for the experimentally observed μs lifetime for D3O

International Nuclear Information System (INIS)

McLoughlin, P.W.; Gellene, G.I.

1990-01-01

The minimum energy pathway (MEP) for H atom addition to H 2 O has been determined by ab initio calculations at the MP3 level using a large Rydberg basis set. In agreement with previous theoretical studies, a local minimum in a C 3v geometry was found lying about 18.4 kcal/mol above the energy of H 2 O + H, but separated from the products by a 3.9 kcal/mol barrier. The well depth is sufficient to contain a quasi-bound zero point level, however, tunneling lifetimes, estimated to be 10 -13 to 10 -12 s, contrast sharply with the experimental results of neutralized ion beam studies which indicate a ∼1 μs lifetime for D 3 O. Exploration of the region of the potential energy surface around the MEP, shows the pathway to preserve a symmetry plane containing the H fragment and bisecting the H 2 O fragment (i.e., C s symmetry) with the dissociation coordinate lying in the A' coordinate subspace. Vibrationally adiabatic potential curves correlating to H 2 O products with excitation in the asymmetric stretch are found to have increased dissociation barriers for increased excitation with ∼μs lifetimes occurring for v ≥ 3. The interpretation that the experimentally observed metastability of D 3 O arises from this essentially dynamical dissociation barrier makes the radical a remarkable example of a quasi-bound species, lasting ∼1 μs with 10.5 kcal/mol of internal energy in excess of the semiclassical dissociation barrier. Isotope effects on the magnitude of possible nonadiabatic kinetic and potential couplings are estimated and discussed in light of the experimental lifetime scaling D 3 16 O>D 3 18 O≥H 3 16 O

Problems in the forecasting of solar particle events for manned missions

Manned spacecraft will require a much improved ability to forecast solar particle events. The lead time required will depend on the use to which the forecast is put. Here we discuss problems of forecasting with the lead times of hours to weeks. Such forecasts are needed for scheduling and carrying out activities. Our present capabilities with these lead times is extremely limited. To improve our capability we must develop an ability to predict fast coronal mass ejections (CMEs). It is not sufficient to observe that a CME has already taken place since by that time it is already too late to make predictions with these lead times. Both to learn how to predict CMEs and to carry out forecasts on time scales of several days to weeks, observations of the other side of the Sun are required. We describe a low-cost space mission of this type that would further the development of an hours-to-weeks forecast capability
