    1980-02-01

    Relaxation diagrams of Hastelloy X (relaxation curves, relaxation design diagrams, etc.) were generated from the creep constitutive equation of Hastelloy X, using inelastic stress analysis code TEPICC-J. These data are in good agreement with experimental relaxation data of ORNL-5479. Three typical inelastic stress analyses were performed for various relaxation behaviors of the high-temperature structures. An attempt was also made to predict these relaxation behaviors by the relaxation curves. (author)

    A worst case, seven element, asymmetric fuel, thermal environment was assumed and a creep relaxation analysis generated. The fuel element clad is .020 inch Hastelloy X. The contact load decreased from 11.6 pounds to 5.87 pounds in 100,000 hours. The residual stresses were then computed for various shutdown times. (U.S.)

    1987-01-01

    An experimental study was completed to determine the corrosion behavior of molybdenum and Hastelloy B, a nickel-based alloy with high molybdenum content, in sulfur and sodium polysulfides (Na/sub 2/S/sub 3/,Na/sub 2/S/sub 4/, Na/sub 2/S/sub 5/) at 623 K. In sulfur, molybdenum corrodes very slowly, with a parabolic rate constant of 3.6 x 10/sup -9/ cm s/sup -1/2/. Hastelloy B shows no measurable corrosion after 100h of exposure to sulfur. The corrosion reaction of molybdenum in Na/sub 2/S/sub 3/ is characterized by the formation of a protective film that effectively eliminates further corrosion after the first 100h of exposure. Hastelloy B, however, corrodes rapidly in Na/sub 2/S/sub 3/, with corrosion rates approaching those of pure nickel under the same conditions. After the first 4h of exposure, the kinetics for the corrosion of Hastelloy B in Na/sub 2/S/sub 3/ follows a linear rate law. The scale morphology has multiple spalled layers of NiS/sub 2/, with some crystallites of NiS/sub 2/ appearing on the leading face of the scale and between the individual scale layers. This spalling causes smaller coupons of the Hastelloy B to corrode faster than larger coupons

    In the creep curve of Hastelloy X, it was difficult to divide it into the three stages of creep. However, these stages were made distinguishable by plotting the relationship between creep rates and time in double-logarithmic coordinates. All the creep data of Hastelloy X, except the isochronous stress-strain curves, required for determining the design stress intensities S sub(o) and S sub(t) were arranged through the Larson-Miller parameter. The isochronous stress-strain curves for a heat of Hastelloy X were derived from the constitutive equations obtained from short-term data. A fairly good agreement between the predicted data and the experimental data was obtained. (auth.)

    In the design of components intended for elevated temperature service as the experimental Very High-Temperature gas-cooled Reactor (VHTR), it is essential to prevent fatigue failure and creep-fatigue failure. The evaluation method which uses design fatigue curves is adopted in the design rules. This report discussed several aspects of these design fatigue curves for Hastelloy-X (-XR) which is considered for use as a heat-resistant alloy in the VHTR. Examination of fatigue data gathered by a literature search including unpublished data showed that Brinkman's equation is suitable for the design curve of Hastelloy-X (-XR), where total strain range Δ epsilon sub(t) is used as independent variable and fatigue life Nsub(f) is transformed into log(log Nsub(f)).

    Creep tests of base metal, weld metal and welded joint of Hastelloy XR, which had the same chemical composition as Hastelloy XR produced for an intermediate heat exchanger of the High-Temperature Engineering Test Reactor, were conducted in simulated primary coolant helium. The weld metal and welded joint showed almost equal to or longer rupture time than the base metal of Hastelloy XR at 850 and 900degC, although they gave shorter rupture time at 950degC under low stress and at 1,000degC. The welded joint of Hastelloy XR ruptured at the base metal region at 850 and 900degC. On the other hand, it ruptured at the weld metal region at 950 and 1,000degC. The steady-state creep rate of weld metal of Hastelloy XR was lower than that of base metal at 850, 900 and 950degC. The creep rupture strengths of base metal, weld metal and welded joint of Hastelloy XR obtained in this study were confirmed to be much higher than the design allowable creep-rupture stress (S R ) of the Design Allowable Limits below 950degC.

    Highlights: ► Hastelloy C22 coatings were prepared by diode laser cladding technique. ► Higher laser speed resulted in smaller grain size. ► Size-effect played the key role in the hardness measurements by different ways. ► Coating with higher laser scanning speed displayed higher nano-scratch resistance. ► Small grain size was beneficial for improvement of coating corrosion resistance. -- Abstract: The Hastelloy C22 coatings H1 and H2 were prepared by laser cladding technique with laser scanning speeds of 6 and 12 mm/s, respectively. Their microstructures, mechanical properties and corrosion resistance were investigated. The microstructures and phase compositions were studied by metallurgical microscope, scanning electron microscope and X-ray diffraction analysis. The hardness and scratch resistance were measured by micro-hardness and nanoindentation tests. The polarization curves and electrochemical impedance spectroscopy were tested by electrochemical workstation. Planar, cellular and dendritic solidifications were observed in the coating cross-sections. The coatings metallurgically well-bonded with the substrate are mainly composed of primary phase γ-nickel with solution of Fe, W, Cr and grain boundary precipitate of Mo 6 Ni 6 C. The hardness and corrosion resistance of steel substrate are significantly improved by laser cladding Hastelloy C22 coating. Coating H2 shows higher micro-hardness than that of H1 by 34% and it also exhibits better corrosion resistance. The results indicate that the increase of laser scanning speed improves the microstuctures, mechanical properties and corrosion resistance of Hastelloy C22 coating

  8. Creep properties of Hastelloy X in a carburizing helium environment

    1982-01-01

    In this work, we investigate the environmental effect on the creep behavior of Hastelloy X at 900 0 C in helium and air. Since helium coolant in HTGR is expected to be carburizing and very weakly oxidizing for most metals, testings were focused on the effect of carburizing and slight oxidation. Carburization decreases secondary creep strain rate and delays tertiary creep initiation. On the other hand, the crack growth rate on the specimen surface is enhanced due to very weak oxidation in helium, therefore the tertiary creep strain rate becomes larger than that in air. The rupture time of Hastelloy X was shorter in helium when compared with in air. Stress versus rupture time curves for both environments do not deviate with each other during up to 5000 hours test, and a ratio of rupture stress in helium to that in air was about 0.9

    1983-01-01

    In order to carry out the structural design of high temperature pipings, intermediate heat exchangers and isolating valves for a multipurpose high temperature gas-cooled reactor, in which coolant temperature reaches 1000 deg C, the creep characteristics of Hastelloy X used as the heat resistant material must be clarified. In addition to usual creep rupture life and the time to reach a specified creep strain, the dependence of creep strain curves on time, temperature and stress must be determined and expressed with equations. Therefore, using the creep data of Hastelloy X given in the literatures, the creep constitutive equation was made. Since the creep strain curves under the same test condition were different according to heats, the sensitivity analysis of the creep constitutive equation was performed. The form of the creep constitutive equation was determined to be Garofalo type. The result of the sensitivity analysis is reported. (Kako, I.)

    Biaxial(tension/torsion) creep and creep-fatigue tests were conducted on Hastelloy XR at 950degC in air. Hastelloy XR is a nickel base solution-annealed heat resistant alloy. Thin-walled tubular test specimens were employed. As results of the creep tests, the von Mises' flow rule was revealed to be applicable very well. Under the torsion load, sufficient growth of voids was necessary to initiate the fracture and this resulted in longer life time compared with that under the tension load. Only a few number of small voids could be observed and very long life times were attained under the compression load. The creep-fatigue tests revealed that superposition of constant torsion load on a cyclic axial load reduced the cycles to failure significantly and the amount of reduction was consistent with the prediction by the linear life fraction rule.

    Highlights: • Cavitation erosion behavior of Hastelloy C-276 was studied by ultrasonic apparatus. • The cavitation-induced precipitates formed in the eroded surface for Hastelloy C-276. • The selective cavitation erosion was found in Hastelloy C-276 alloy. - Abstract: The cavitation erosion behavior of Hastelloy C-276 alloy was investigated using an ultrasonic vibratory apparatus and compared with that of 316L stainless steel. The mean depth of erosion (MDE) and erosion rate (ER) curves vs. test time were attained for Hastelloy C-276 alloy. Morphology and microstructure evolution of the eroded surface were observed by scanning electron microscopy (SEM) and field emission scanning electron microscopy (FESEM) and the predominant erosion mechanism was also discussed. The results show that the MDE is about 1/6 times lower than that of the stainless steel after 9 h of testing. The incubation period of Hastelloy C-276 alloy is about 3 times longer than that of 316L stainless steel. The cavitation-induced nanometer-scaled precipitates were found in the local zones of the eroded surface for Hastelloy C-276. The selective cavitation erosion was found in Hastelloy C-276 alloy. The formation of nanometer-scaled precipitates in the eroded surface may play a significant role in the cavitation erosion resistance of Hastelloy C-276.

    Hastelloy X, an Ni--Cr--Fe--Mo alloy, may be an important structural alloy for components of gas-cooled reactor systems. Expected applications of this alloy in the High-Temperature Gas-Cooled Reactor (HTGR) are discussed, and the development of interim mechanical properties and supporting data are reported. Properties of concern include tensile, creep, creep-rupture, fatigue, creep-fatigue interaction, subcritical crack growth, thermal stability, and the influence of helium environments with controlled amounts of impurities on these properties. In order to develop these properties in helium environments that are expected to be prototypic of HTGR operating conditions, it was necessary to construct special environmental test systems. Details of construction and operating parameters are described. Interim results from tests designed to determine the above properties are presented. To date a fairly extensive amount of information has been generated on this material at Oak Ridge National Laboratory and elsewhere concerning behavior in air, which is reviewed. However, only limited data are available from tests conducted in helium. Comparisons of the fatigue and subcritical growth behavior in air between Hastelloy X and a number of other structural alloys are given

    Hastelloy alloy X has been a successful high-temperature structural material for more than two decades. Recently, Hastelloy alloy X sheet has been selected as a prime structural material for the proposed Brayton Isotope Power System (BIPS). The material also sees extensive application in the High-Temperature Gas-Cooled Reactor (HTGR). Design of these systems requires a detailed consideration of the high-temperature creep properties of this material. Therefore, available creep, creep-rupture, and relaxation data for Hastelloy alloy X were collected and analyzed to yield mathematical representations of the behavior for design use

    1983-01-01

    A creep constitutive equation of Hastelloy X was obtained from available experimental data. A sensitivity analysis of this creep constitutive equation was carried out. As the result, the following were revealed: (i) Variations in creep behavior with creep constitutive equation are not small. (ii) In a simpler stress change pattern, variations in creep behavior are similar to those in the corresponding fundamental creep characteristics (creep strain curve, stress relaxation curve, etc.). (iii) Cumulative creep damage estimated in accordance with ASME Boiler and Pressure Vessel Code Case N-47 from a stress history predicted by ''the standard creep constitutive equation'' which predicts the average behavior of creep strain curve data is not thought to be on the safe side on account of uncertainties in creep damage caused by variations in creep strain curve.

  16. Creep properties of 20% cold-worked Hastelloy XR

    Kurata, Y.

    1996-01-01

    The creep properties of Hastelloy XR, in solution-treated and in 20% cold-worked conditions, were studied at 800, 900 and 1000 C. At 800 C, the steady-state creep rate and rupture ductility decrease, while rupture life increases after cold work to 20%. Although the steady-state creep rate and ductility also decrease at 900 C, the beneficial effect on rupture life disappears. Cold work to 20% enhan ces creep resistance of this alloy at 800 and 900 C due to a high density of dislocations introduced by the cold work. Rupture life of the 20% cold-worked alloy becomes shorter and the steady-state creep rate larger at 1000 C during creep of the 20% cold-worked alloy. It is emphasized that these cold work effects should be taken into consideration in design and operation of high-temperature structural components of high-temperature gas-cooled reactors. (orig.)

    Creep properties of weldment made from Hastelloy Alloy XR base metals and filler metals for the High Temperature Engineering Test Reactor (HTTR) components were examined by means of creep and creep rupture tests at 900 and 950degC in air. The results obtained are as follows: creep rupture strength was nearly equal or higher than that of Hastelloy Alloy XR master curve and was much higher than design creep rupture strength [S R ]. Furthermore, creep rupture strength and ductility of the present filler metal was in the data band in comparison with those of the previous filler metals. It is concluded from these reasons that this filler metal has fully favorable properties for HTTR uses. (author)

    With the goal of understanding the invalidation problem of irradiated Hastelloy N alloy under the condition of intense irradiation and severe corrosion, the corrosion behavior of the alloy after He + ion irradiation was investigated in molten fluoride salt at 700 °C for 500 h. The virgin samples were irradiated by 4.5 MeV He + ions at room temperature. First, the virgin and irradiated samples were studied using positron annihilation lifetime spectroscopy (PALS) to analyze the influence of irradiation dose on the vacancies. The PALS results showed that He + ion irradiation changed the size and concentration of the vacancies which seriously affected the corrosion resistance of the alloy. Second, the corroded samples were analyzed using synchrotron radiation micro-focused X-ray fluorescence, which indicated that the corrosion was mainly due to the dealloying of alloying element Cr in the matrix. Results from weight-loss measurement showed that the corrosion generally correlated with the irradiation dose of the alloy. (author)

    Highlights: •Corrosion behaviors of Hastelloy-N and -B3 in molten FLiNaK salt at 700 °C. •The alleviated corrosion rate of alloys was observed after long-hour immersion. •Long-term corrosion rate was limited by diffusion from matrix to alloy surface. •Corrosion pattern transferred from intergranular corrosion into general corrosion. •Presence of minor H 2 O did not greatly influence the long-term corrosion behavior. -- Abstract: This study investigated long-term corrosion behaviors of Ni-based Hastelloy-N and Hastelloy-B3 under moisture-containing molten alkali fluoride salt (LiF–NaF–KF: 46.5–11.5–42%) environment at an ambient temperature of 700 °C. The Hastelloy-N and Hastelloy-B3 experienced similar weight losses for tested duration of 100–1000 h, which was caused by aggregate dissolution of Cr and Mo into FLiNaK salts. The corrosion rate of both alloys was high initially, but then reduced during the course of the test. The alleviated corrosion rate was due to the depletion of Cr and Mo near surface of the alloys and thus the long-term corrosion rate was controlled by diffusion of Cr and Mo outward to the alloy surface. The results of microstructural characterization revealed that the corrosion pattern for both alloys tended to be intergranular corrosion at early stage of corrosion test, and then transferred to general corrosion for longer immersion hours

    In order to clarify the creep properties of EB welds on Hastelloy X which is one of the candidate alloys for components of VHTR, creep tests on EB weld metal and welded joint were carried out. The results were discussed in comparison with those of base metal and TIG welds. Further, EB welds were evaluated from the standpoint of high temperature structural design. The results obtained are summarized as follows. 1) Both creep rupture strengths of EB weld metal and EB welded joint are almost equal to that of base metal, but those of TIG welds are lower than base metal. As for the secondary creep rate, EB weld metal is higher and TIG weld metal is lower than base metal. As for the time to onset of tertiary creep, no remarkable difference among base metal, EB weld metal and TIG weld metal is observed. 2) In case of EB weld metal, although anisotropy is slightly observed, the ductility is same or more as compared with base metal. In case of TIG weld metal, on the contrary, anisotropy is not observed and the ductility is essentially low. 3) Such rupture morphology of EB weld metal as appears to have resulted from interconnection of voids which occurred at grain boundary is similar to base metal. In case of TIG weld metal, however, many cracks with sharp tips are observed at grain boundary, and the rupture appears to have occurred in brittle by propagation and connection of the cracks. 4) It can be said from the standpoint of high temperature structural design that EB welding is very suitable to welding for structure where creep effects are significant, because both of the creep ductility and the rupture strength are almost equal to those of base metal.

    1992-01-01

    A series of constant load and temperature creep rupture tests and varying load and/or temperature creep rupture tests was carried out on a nickel-base heat-resistant alloy Hastelloy XR, which was developed for applications in the High-Temperature Engineering Test Reactor, at temperatures ranging from 850 to 1000deg C in order to examine the applicability of the conventional creep damage rules, i.e., the life fraction, the strain fraction and their mixed rules. The life fraction rule showed the best applicability of these three criteria. The good applicability of the rule was considered to result from the fact that the creep strength of Hastelloy XR was not strongly affected by the change of the chemical composition and/or the microstructure during exposure to the high-temperature simulated HTGR helium environment. In conclusion the life fraction rule is applicable in engineering design of high-temperature components made of Hastelloy XR. (orig.)

    Tellurium, which is a fission product in nuclear reactor fuels, can embrittle the surface grain boundaries of nickel-base structural materials. This report summarizes results of an experimental investigation conducted to understand the mechanism and to develop a means of controlling this embrittlement in the alloy Hastelloy N. The addition of a chromium telluride to salt can be used to provide small partial pressures of tellurium simulating a reactor environment where tellurium appears as a fission product. The intergranular embrittlement produced in Hastelloy N when exposed to this chromium telluride-salt mixture can be reduced by adding niobium to the Hastelloy N or by controlling the oxidation potential of the salt in the reducing range

    Results are presented for strain-controlled fatigue and tensile tests for two nickel-base, solution-hardened reference structural alloys for use in several High-Temperature Gas-Cooled Reactor (HTGR) concepts. These alloys, Hastelloy X and Inconel 617, were tested from room temperature to 871 0 C in air and impure helium. Materials were tested in both the solution-annealed and the preaged conditios, in which aging consisted of isothermal exposure at one of several temperatures for periods of up to 20,000 h. Comparisons are given between the strain-controlled fatigue lives of these and several other commonly used alloys, all tested at 538 0 C. An analysis is also presented of the continuous cycle fatigue data obtained from room temperature to 427 0 C for Hastelloy G, Hastelloy X, Hastelloy C-276, and Hastelloy C-4, an effort undertaken in support of ASME code development

    Full Text Available This paper presents a finite element analysis of the stress distribution in the end milling operation of nickel-based superalloy HASTELLOY C-2000. Commercially available finite element software was used to develop the model and analyze the distribution of stress components in the machined surface of HASTELLOY C-22HS following end milling with coated carbide tools. The friction interaction along the tool-chip interface was modeled using the Coulomb friction law. It was found that the stress had lower values under the cut surface and that it increased gradually near the cutting edge.

    Creep and stress rupture tests on three heats of Hastelloy X differing in the manufacturing process were carried out at 800 0 C, 900 0 C and 1000 0 C. Interpretation of the observed creep properties was made, and a method for predicting necessary design data from the experimentally obtained results was discussed. The results are as follows. (1) It was difficult to separate the primary, secondary and tertiary creep stages in the creep curve of Hastelloy X of the present tests. However, those were made distinguishable by plotting the results in a double-logarithmic coordinates. From these creep rate curves, the primary and secondary creep rates and the times to the initiation of secondary and tertiary creeps were derived. (2) It is considered that the same stress and temperature dependences between the primary and secondary creep rates exist in the creep behaviour of Hastelloy X of the present tests. (3) All the creep data, except the isochronous stress-strain curve, required for the design such as stress vs. rupture time, stress vs. secondary creep rate and stress vs. time to initiation of tertiary creep could be arranged through the Larson-Miller parameter. On the other hand, the isochronous stress-strain curve was figured out by estimating creep curves. The constitutive equations of creep for a heat of Hastelloy X proposed in this paper and the isochronous stress-strain curves derived from these constitutive equations were consistent with the experimental data obtained for the corresponding material.

    The oxidation in air of two refractory alloys (Nicral D and Hastelloy X) has been studied at 900 and 1100 deg. C, by means of recording thermo-balances and microscopic cross section examination. At 900 deg. C, the surface oxidation rates of the two alloys are quite similar, but at 1100 deg. C the alloy Nicral D oxidizes faster than the alloy Hastelloy X. On the other hand, after heating at 1100 deg. C for 150 hours, Nicral D shows both intergranular oxidation and a small amount of internal oxidation, whereas Hastelloy X is especially subject to internal oxidation. In addition, two descaling methods were compared: an electrolytic method, in a sodium hydroxide-sodium carbonate bath, and a chemical method using a sodium nitrate-sodium peroxide bath; the latter appears suitable only for Hastelloy X.

    The composition of the eta carbide in Hastelloy N containing 0.7 wt percent Si in the alloy approaches M 12 C, rather than M 6 C as indicated in the alloy literature. The silicon content of the eta phase in this case was about 25 at. percent, much higher than has been observed in less highly alloyed material. The data do not permit a definition of the limiting compositions of the phases

    The characteristics of weld defects in the electron beam (EB) welding and the tungsten inert gas (TIG) arc welding for Hastelloy-XR, a modified version of Hastelloy-X, are clarified through the bead-on-plate test and the Trans-Varestraint test. Based on the results, weldabilities on EB and TIG weldings for Hastelloy-XR are discussed and found to be almost the same as Hastelloy-X. The creep rupture behaviors of the welded joints are evaluated by employing data on creep properties of the base and the weld metals. According to the evaluation, the creep rupture strength of the EB-welded joint may be superior to that of the TIG-welded joint. The corrosion test in helium containing certain impurities is conducted for the weld metals. There is no significant difference of such corrosion characteristics as weight gain, internal oxidation, depleted zone, and so on between the base and the weld metals. Those are superior to Hastelloy-X

    Both the 316L stainless steel and Hastelloy C-22 gave satisfactory corrosion performance in the simulated test environments. They were subjected to 100 day weight loss corrosion tests and electrochemical potentiodynamic evaluation. This activity supports confirmation of the design basis for the materials of construction of process vessels and equipment used to handle the feed to the LAW-melter evaporator. BNFL process and mechanical engineering will use the information derived from this task to select material of construction for process vessels and equipment

    Hastelloy N alloy was implanted with 30 keV, 5 × 10{sup 16} ions/cm{sup 2} helium ions at room temperature, and subsequent annealed at 600 °C for 1 h and further annealed at 850 °C for 5 h in vacuum. Using elastic recoil detection analysis (ERDA) and transmission electron microscopy (TEM), the depth profiles of helium concentration and helium bubbles in helium-implanted Hastelloy N alloy were investigated, respectively. The diffusion of helium and molybdenum elements to surface occurred during the vacuum annealing at 850 °C (5 h). It was also observed that bubbles in molybdenum-enriched region were much larger in size than those in deeper region. In addition, it is worth noting that plenty of nano-holes can be observed on the surface of helium-implanted sample after high temperature annealing by scanning electron microscope (SEM). This observation provides the evidence for the occurrence of helium release, which can be also inferred from the results of ERDA and TEM analysis.

    1980-01-01

    Effect of grain size and cold working on creep, creep rupture, low cycle fatigue and tensile strengths of Hastelloy X were studied at temperatures ranging from 800 to 1000 0 C. In order to apply these data to design, the allowable design stresses were estimated by expanding the criteria of ASME Code Case 1592 to such a high temperature range. The allowable design stress increased, on the other hand, the low cycle fatigue life decreased with increasing grain size. Cold working up to a ratio of 5 per cent may not be a serious problem in design, because the allowable design stress and the fatigue life were little affected. The cause of these variations in strength was discussed by examining the initiation and growth of cracks, and the microstructures. (author)

    Creep tests under constant stress were conducted on a nickel-base heat-resistant alloy, Hastelloy XR, in air at 950degC. Minimum creep strain rate, time to the onset of tertiary creep and time to rupture were obtained as a function of applied stress. Then, a creep constitutive equation was made based on the Garofalo formula for primary and secondary creep and based on the Kachanov-Rabotnov formula for tertiary creep, which could represent fairly well the experimental creep deformation curves under the constant stress conditions. The creep deformation under the constant load condition corresponding to the stress increment was analysed using the creep constitutive equation and strain hardening law. Then the calculated creep strain showed slightly higher value than the experimental creep strain, and the calculated life was shorter than the experimental one. (author)

    1979-03-01

    Creep and rupture behaviours of Hastelloy-X and its modified version were examined with special reference to the effect of different test environments; i.e. air, high vacuum and the simulated HTR helium coolant. The respective environments showed different effects. The vacuum environment of about 10 -8 torr. gave best reproducible behaviour with essentially no surface-to-volume ratio effect. Such size effect was significant in the other two environments. The simulated HTR environment was characterized in its potentiality of both oxidizing selected alloy constituents and carburization. The observed behaviour was attributed to the depletion of strengthning solute elements caused by the surface reactions and the associated solid state reactions. (author)

    To model the creep curves of the Hastelloy-X alloy which is being considered as a candidate material for the VHTR (Very High Temperature gas-cooled Reactor) components, full creep curves were obtained by constant-load creep tests for different stress levels at 950 C degrees. Using the experimental creep data, the creep curves were modeled by applying the Theta projection method. A number of computing processes of a nonlinear least square fitting (NLSF) analysis was carried out to establish the suitably of the four Theta parameters. The results showed that the Θ 1 and Θ 2 parameters could not be optimized well with a large error during the fitting of the full creep curves. On the other hand, the Θ 3 and Θ 4 parameters were optimized well without an error. For this result, to find a suitable cutoff strain criterion, the NLSF analysis was performed with various cutoff strains for all the creep curves. An optimum cutoff strain range for defining the four Theta parameters accurately was found to be a 3% cutoff strain. At the 3% cutoff strain, the predicted curves coincided well with the experimental ones. The variation of the four Theta parameters as the function of a stress showed a good linearity, and the creep curves were modeled well for the low stress levels. Predicted minimum creep rate showed a good agreement with the experimental data. Also, for a design usage of the Hastelloy-X alloy, the plot of the log stress versus log the time to a 1% strain was predicted, and the creep rate curves with time and a cutoff strain at 950 C degrees were constructed numerically for a wide rang of stresses by using the Theta projection method.

    We have grown MgB 2 on SiC buffer layer by using metallic Hastelloy tape as the substrate. Hastelloy tape was chosen for its potential practical applications, mainly in the power cable industry. SiC buffer layers were deposited on Hastelloy tapes at 400, 500, and 600 degrees C by using a pulsed laser deposition method, and then by using a hybrid physical-chemical vapor deposition technique, MgB 2 films were grown on the three different SiC buffer layers. An enhancement of critical current density values were noticed in the MgB 2 films on SiC/Hastelloy deposited at 500 and 600 degrees C. From the surface analysis, smaller and denser grains of MgB 2 tapes are likely to cause this enhancement. This result infers that the addition of SiC buffer layers may contribute to the improvement of superconducting properties of MgB 2 tapes.

    Hastelloy C22 coating was prepared on substrate of Q235 steel by high power multilayer laser cladding. The microstructure, hardness and anti-corrosion properties of coating were investigated. The corrosion tests in 3.5% NaCl solution were carried out with variation of impingement angle and velocity, and vibration frequency of sample. The microstructure of coating changes from equiaxed grain at the top surface to dendrites oriented at an angle of 60° to the substrate inside the coating. The corrosion rate of coating increases with the increase of impingement angle and velocity, and vibrant frequency of sample. Corrosion mechanisms relate to repassivation and depassivation of coating according to electrochemical measurements. Above results show that multilayer laser cladding can endow Hastelloy C22 coating with fine microstructures, high hardness and good anti-corrosion performances.

    Typical HTGR candidate alloys can carburize when exposed to simulated service environments. The carbon concentration gradients so formed give rise to internal stresses which could cause dilation. Studies performed with Hastelloy X and Alloy 800H showed that dilations of up to almost 1% can occur at 1000 0 C when carbon pickup is high. Dilation was normally observed only when the carbon increase was >1000 μg/cm 2 and ceased when diffusing carbon reached the center of the specimen. (Auth.)

    In the design of the high-temperature components, it is often required to predict the creep rupture life under the conditions in which the stress and/or temperature may vary by using the data obtained with the constant load and temperature creep rupture tests. Some conventional creep damage rules have been proposed to meet the above-mentioned requirement. Currently only limited data are available on the behavior of Hastelloy XR, which is a developed alloy as the structural material for high-temperature components of the High-Temperature Engineering Test Reactor (HTTR), under varying stress and/or temperature creep conditions. Hence a series of constant load and temperature creep rupture tests as well as varying load and temperature creep rupture tests was carried out on two kinds of Hastelloy XR alloys whose boron content levels are different, i.e., below 10 and 60 mass ppm. The life fraction rule completely fails in the prediction of the creep rupture life of Hastelloy XR with 60 mass ppm boron under varying load and temperature conditions though the rule shows good applicability for Hastelloy XR with below 10 mass ppm boron. The change of boron content level of the material during the tests is the most probable source of impairing the applicability of the life fraction rule to Hastelloy XR whose boron content level is 60 mass ppm. The modified life fraction rule has been proposed based on the dependence of the creep rupture strength on the boron content level of the alloy. The modified rule successfully predicts the creep rupture life under the two stage creep test conditions from 1000 to 900degC. The trend observed in the two stage creep tests from 900 to 1000degC can be qualitatively explained by the mechanism that the oxide film which is formed during the prior exposure to 900degC plays the role of the protective barrier against the boron dissipation into the environment.

    Full Text Available The requirements for welded aircraft parts have become increasingly severe, especially in terms of the reproducibility of the geometry and metallurgical grade of the weld bead. Laser welding is a viable method of assembly to meet these new demands, because of automation, to replace the manual TIG welding process. The purpose of this study is to determine the weldability of Hastelloy X and Haynes 188 alloys by the butt welding process with a Nd:YAG laser. To identify the influential parameters of the welding process (laser power, feed rate, focal diameter and flow of gas while streamlining testing, an experimental design was established with the CORICO software using the graphic correlation method. The position of the focal point was fixed at 1/3 of the thickness of the sheet. The gas flow rate and the power of the beam have a major effect on the mechanical properties and geometry of the weld. The strength of the weld is comparable to that of the base metal. However, there is a significant decrease in the elongation at break of approximately 30%. The first observations of the cross section of the weld by scanning electron microscopy coupled with EBSD analysis show a molten zone presenting dendritic large grains compared to the equiaxed grains of the base metals without a heat affected zone.

    The volumetric swelling and hardening effect of irradiated Hastelloy N alloy were investigated in this paper. 7 MeV and 1 MeV Xe ions irradiations were performed at room temperature (RT) with irradiation dose ranging from 0.5 to 27 dpa. The volumetric swelling increases with increasing irradiation dose, and reaches up to 3.2% at 27 dpa. And the irradiation induced lattice expansion is also observed. The irradiation induced hardening initiates at low ion dose (≤1dpa) then saturates with higher ion dose. The irradiation induced volumetric swelling may be ascribed to excess atomic volume of defects. The irradiation induced hardening may be explained by the pinning effect where the defects can act as obstacles for the free movement of dislocation lines. And the evolution of the defects' size and number density could be responsible for the saturation of hardness. - Highlights: •Irradiation Swelling: The irradiation induced volumetric swelling increases with ion dose. •Irradiation Hardening: The irradiation hardening initiates below 1 dpa, then saturates with higher ion dose (1–10 dpa). •Irradiation Mechanism: The irradiation phenomena are ascribed to the microstructural evolution of the irradiation defects.

    Laser treatment of Hastelloy C276 alloy is carried out under the high pressure nitrogen assisting gas environment. Morphological and metallurgical changes in the laser treated layer are examined using the analytical tools including, scanning electron and atomic force microscopes, X-ray diffraction, energy dispersive spectroscopy, and Fourier transform infrared spectroscopy. Microhardness is measured and the residual stress formed in the laser treated surface is determined from the X-ray data. The hydrophibicity of the laser treated surface is assessed using the sessile drop method. Friction coefficient of the laser treated layer is obtained incorporating the micro-tribometer. It is found that closely spaced laser canning tracks create a self-annealing effect in the laser treated layer and lowers the thermal stress levels through modifying the cooling rates at the surface. A dense structure, consisting of fine size grains, enhances the microhardness of the surface. The residual stress formed at the surface is compressive and it is in the order of -800 MPa. Laser treatment improves the surface hydrophobicity significantly because of the formation of surface texture composing of micro/nano-pillars.

  4. Temperature dependence of creep properties of cold-worked Hastelloy XR

    1995-01-01

    The creep properties of Hastelloy XR, in a solution treated, 10% or 20% cold-worked condition, were investigated at temperatures from 800 to 1,000degC for the duration of creep tests up to about 2,500 ks. At 800 and 850degC, the steady-state creep rate and rupture ductility decreased and the rupture life increased after cold work of 10% or 20%. Although the rupture life of the 10% cold-worked alloy was longer at 900degC than that of the solution treated one, the rupture lives of the 10% cold-worked and solution treated alloys were almost equal at 950degC, which is the highest helium temperature in an intermediate heat exchanger of the High Temperature Engineering Test Reactor (HTTR). The beneficial effect of 10% cold work on the rupture life and the steady-state creep rate disappeared at 1,000degC. The beneficial effect of 20% cold work disappeared at 950degC because significant dynamic recrystallization occurred during creep. While rupture ductility of this alloy decreased after cold work of 10% or 20%, it recovered to a considerable extend at 1,000degC. It is emphasized that these cold work effects should be taken into consideration in design, operation and residual life estimation of high temperature components of the HTTR. (author)

    Creep tests on circumferentially TIG-welded Hastelloy x cylinders were carried out under internal pressure for the investigation of structural behavior of welded components in high temperature environment. The creep rupture strength of TIG-welded cylinders was much lower than that of non-welded cylinders, while such reduction was not found in uniaxial creep tests on TIG-welded bars. It was deduced that the reduction was due to the low ductility (ranging from 1 to 5%) of the weld metal to which enhanced creep was induced by the adjacent base metal whose creep strain rate was much higher than that of the weld metal. Therefore, uniaxial creep tests on bar specimens is not sufficient for proper assessment of the creep rupture strength of welded components. Both creep strain rate and creep ductility should be concerned for the assessment. Creep tests by using components such as cylinder under internal pressure are recommendable for the confirmation of creep strength of welded structures and components. (author)

    The present paper investigates early-stage-creep damage of Hastelloy XR and XR-II alloys, modified versions of Hastelloy X alloy, which have been developed in Japan as most promising candidate structural alloys for Japanese high-temperature gas-cooled reactors (HTGRs). Creep tests were made on Hastelloy XR forging, tube and XR-II tube at 1,123 to 1,273 K in a simulated HTGR helium gas environment. The tests were interrupted at different strain levels of up to 5 % in order to evaluate creep damage via intergranular voids. The void sizes along grain boundaries and the A-parameter, the ratio of the number of damaged grain boundaries, on which one or more voids are found, to that of the total grain boundaries observed are used in order to evaluate creep damage. Statistical analysis of the A-parameter as well as the void sizes reveals that the values of the parameter show wide variations and follow the Weibull distribution, reflecting spatial randomness of the voids. The void sizes along grain boundaries, on the other hand, follow the log-normal distribution. The maximum void size d max and the mean value of the A-parameter A m are calculated and plotted against interruption creep strain ε int . The resultant d max vs. ε int and A m vs. ε int diagrams show that Hastelloy XR forging had suffered more damage than Hastelloy XR tube; nevertheless, the forging has longer interruption life, or the time to reach a given interruption creep strain. The result indicates that grains may have been deformed more easily in Hastelloy XR in the form of tube than in the form of forging. The diagrams also imply that the addition of boron has suppressed the nucleation as well as the growth of voids and thus has brought about longer interruption life of Hastelloy XR-II. (author)

    TiC/hastelloy composites with suitable thermal expansion and excellent electrical conductivity are promising candidates for IT-SOFC interconnect. In this paper, the TiC/hastelloy composites are fabricated by in-situ reactive infiltration, and the oxidation resistance of composites is optimized by increasing graphite particle size. Results show that the increase of graphite particles size from 1 μm to 40 μm reduces TiC particle size from 2.68 μm to 2.22 μm by affecting the formation process of TiC. Moreover, the decrease of TiC particles size accelerates the fast formation of dense and continuous TiO2/Cr2O3 oxide layer, which bring down the mass gain (800 °C/100 h) from 2.03 mg cm-2 to 1.18 mg cm-2. Meanwhile, the coefficient of thermal expansion decreases from 11.15 × 10-6 °C-1 to 10.80 × 10-6 °C-1, and electrical conductivity maintains about 5800 S cm-1 at 800 °C. Therefore, the decrease of graphite particle size is one simple and effective route to optimize the oxidation resistance of composites, and meantime keeps suitable thermal expansion and good electrical conductivity.

    Commercially prepared aluminide coatings on Hastelloy X and Inconel 617 substrates were exposed to controlled-impurity helium at 850 0 and 950 0 C for 3000 h. Optical and scanning electron (SEM) microscopy, electron microprobe profiles, and SEM X-ray mapping were used to evaluate and compare exposed and unexposed control samples. Four coatings were evaluated: aluminide, aluminide with platinum, aluminide with chromium, and aluminide with rhodium. With extended time at elevated temperature, nickel diffused into the aluminide coatings to form epsilon-phase (Ni 3 Al). This diffusion was the primary cause of porosity formation at the aluminide/alloy interface

    In this study, the effects of machining parameters on surface roughness (Ra) and tool life (Tl) were investigated in the milling of Hastelloy C22 alloy with TiAlN-coated carbide inserts. A number of milling experiments were conducted using the L_2_7 (3"3) Taguchi orthogonal array on a CNC milling machine under different cutting conditions (dry, compressed air and wet). The cutting condition, cutting speed and feed rate were determined as the essential machining parameters. Analysis of variance (ANOVA) and signal-to-noise (S/N) ratio were employed to evaluate the effects of the machining parameters on Ra and Tl, and prediction models were created using quadratic regression analyses. The results revealed that the feed rate and cutting condition were the most influential factors on surface roughness and flank wear. The maximum tool life was achieved under wet cutting condition using a cutting speed of 30 x min"-"1 and a feed rate of 0.08 mm x rev"-"1, while the minimum surface roughness value was obtained under wet cutting condition using a cutting speed of 50 m x min"-"1 and the same feed rate. Using the optimum cutting parameters for Tl (30 m x min"-"1, 0.08 mm x rev"-"1), increases of 234 % and 67 % in tool life were observed under wet and compressed air cutting conditions, respectively, compared to the dry cutting condition.

    Polarization and electrochemical impedance spectrometry curves are presented and discussed. These curves make it possible to ascertain the corrosion domains and to compare the slow and fast kinetics (voltammetry) of different stainless steel alloys. These corrosion kinetics, the actual or simulated tritiated water redox potentials, and the corrosion potentials provide a classification of the steels studied here: 316L, Hastelloy, Maraging, Inconel 600, Elgiloy, carbon steel and TiN and NiCr deposits. From the results it can be concluded that Hastelloy and Elgiloy have the best corrosion resistance. (author). 49 refs., 695 figs., tabs.

    This paper presents to develop of the response surface design model to predict the surface roughness for end-milling operation of Hastelloy C-2000 using uncoated carbide insert. Mathematical model is developed to study the effect of three input cutting parameters includes the feed rate, axial depth of cut and cutting speed. Design of experiments (DOE) was implemented with the aid of the statistical software package. Analysis of variance (ANOVA) has been performed to verify the fit and adequacy of the developed mathematical model. The result shows that the feed rate gave the more effect on the both prediction values of Ra compared to the cutting speed and axial depth of cut. SEM and EDX analyses were performed in different cutting conditions. It can be concluded that the feed rate and cutting force give the higher impact to influence the machining characteristics of surface roughness. Thus, the optimizing the cutting conditions are essential in order to improve the surface roughness in machining of Hastlelloy C-2000.

    Machining parameters has an important factor on tool wear and surface finish, for that the manufacturers need to obtain optimal operating parameters with a minimum set of experiments as well as minimizing the simulations in order to reduce machining set up costs. The cutting speed is one of the most important cutting parameter to evaluate, it clearly most influences on one hand, tool life, tool stability, and cutting process quality, and on the other hand controls production flow. Due to more demanding manufacturing systems, the requirements for reliable technological information have increased. For a reliable analysis in cutting, the cutting zone (tip insert-workpiece-chip system) as the mechanics of cutting in this area are very complicated, the chip is formed in the shear plane (entrance the shear zone) and is shape in the sliding plane. The temperature contributed in the primary shear, chamfer and sticking, sliding zones are expressed as a function of unknown shear angle on the rake face and temperature modified flow stress in each zone. The experiments were carried out on a CNC lathe and surface finish and tool tip wear are measured in process. Machining experiments are conducted. Reasonable agreement is observed under turning with high depth of cut. Results of this research help to guide the design of new cutting tool materials and the studies on evaluation of machining parameters to further advance the productivity of nickel based alloy Hastelloy - 276 machining.

    Creep-rupture testing was conducted on 1 1/4 Cr-1 Mo steel, Alloy 800H and Hastelloy Alloy X in flowing helium containing nominal concentration of following gases: 1500 μatm H 2 , 450 μatm CO, 50 μatm CH 4 , 50 μatm H 2 O and 5 μatm CO 2 . This environment is believed to represent maximum permissible levels of impurities in the primary coolant for the steam-cycle system of a high-temperature gas-cooled reactor (HTGR) when it is operating continuously with a water and/or steam leak at technical specification limits. Two or three heats of material for each alloy were investigated. Tests were conducted at 482 0 C and 760 0 C (1200 0 F and 1400 0 F) for Alloy 800H, and at 760 0 C and 871 0 C (1400 0 F and 1600 0 F) for Hastelloy Alloy X for times up to 10,000 h. Selected tests were performed on same heat of material in both air and helium environments to make a direct comparison of creep-rupture behaviors between two environments. Metallurgical evaluation was performed on selected post test specimens with respect to gas-metal interactions which included oxidation, carburization and/or decarburization. Correlation between gaseous corrosion and creep-rupture behavior was attempted. Limited tests were also performed to investigate the specimen size effects on creep-rupture behavior in the helium environment

    The preliminary structural design guidelines for the experimental multi-purpose very-high temperature gas-cooled reactor have recently been prepared. The components of the primary system operating at temperatures of creep dominant range are grouped in those of pressure and temperature boundaries respectively. In the material selection, 2 1/4Cr-1Mo steel is chosen for the former and Hastelloy-X for the latter taking into account of material properties at operating temperature. Deriving from the literature in the field, material design data of the alloys are established in design forms such as Sy, So, Sm, St, 100% of minimum stress to rupture, design fatigue curves, isochronous stress-strain curves, creep-fatigue interaction damage factor and so on, which are defined in ASME Code Section III, Code Case 1592.

    The superconductor industry considers cold-rolled austenitic stainless 310S steel a less expensive substitute for Hastelloy X as a substrate for coated superconductor. However, the mechanical properties of cold-rolled 310S substrate degrade significantly in the superconductor deposition process. To overcome this, we applied hot rolling at 900 °C (or 1000 °C) to the 310S substrate. To check the property changes, a simulated annealing condition equivalent to that used in manufacturing was determined and applied. The effects of the hot rolling on the substrate were evaluated by analyzing its physical properties and texture.

    Sheet samples of Inconel-625, Hastelloy-X280 and Incoloy-800 were tested, in the solution annealed and in the solution annealed + 20% cold worked + 800°C tempered condition, in steam with a velocity of 5 m/sec. at 550, 650 and 750°C and in steam with a volocity of 15 and 85 m/sec. at 550°C. At 550°C and 750°C the samples were tested in the heat treated, annealed or tempered and the heat treated + electropolished condition. At 650°C moreover as heat treated + ground and pickled samples were tested. Post-corrosion sample investigations involved measurement of the adherent oxide thickness, the total amount of corroded metal, the metal loss to system, and the metallographic and microprobe investigation of the adherent oxide film and adjacent diffusion disturbed alloy layer. The results obtained up to 6000 hours exposure time showed that the surface treatment has a decisive influence on the corrosion behaviour of all three alloys tested. The differences in the corrosion data for the two heat treatment conditions are small. The influence of the steam velocity, as tested at 550°C, on the initial corrosion rate was surprisingly high, while the long-term linear corrosion rates are only slightly influenced by the gas velocity. In general the linear corrosion rates were low, 1-5 mg/dm 2 month, and not consistently affected by the test-temperature. The metal loss to system values were 2 <15 mg/dm 2 in the low velocity steam at all three test temperatures and <30 mg/dm 2 in the high velocity steam at 550°C. The metallographic and microprobe examinations revealed no remarkable results, as compared with the results of analogous tests reported in literature. (author)

    The aim of this work is the selection of structural materials that can be used in the temperature range 600-900 0 C for a gas cooled space reactor producing electricity. Superalloys fit best the temperature range required. Five nickel base alloys are chosen for their good mechanical behaviour: HAYNES 230, HASTELLOY S, HASTELLOY X, HASTELLOY XR and PYRAD 38D. Metallography, tensile and hardness tests are realized. Sample contraction is evidenced for some creep tests, under low stress: 20MPa at 800 0 C, on HAYNES 230 and HASTELLOY X, probably related to the structural evolution of these materials corresponding to a decrease of the crystal parameter [fr

    Fullam, H.T.

    1981-12-01

    The Strontium Heat Source Development Program began at the Pacific Northwest Laboratory (PNL) in 1972 and is scheduled to be completed by the end of FY-1981. The program is currently funded by the US Department of Energy (DOE) By-Product Utilization Program. The primary objective of the program has been to develop the data and technology required to permit the licensing of power systems for terrestrial applications that utilize 90 SrF 2 -fueled radioisotope heat sources. A secondary objective of the program has been to design and qualification-test a general purpose 90 SrF 2 -fueled heat source. The effort expended in the design and testing of the heat source is described. Detailed information is included on: heat source design, licensing requirements, and qualification test requirements; the qualification test procedures; and the fabrication and testing of capsules of various materials. The results obtained in the qualification tests show that the outer capsule design proposed for the 90 SrF 2 heat source is capable of meeting current licensing requirements when Hastelloy S is used as the outer capsule material. The data also indicate that an outer capsule of Hastelloy C-4 would probably also meet licensing requirements, although Hastelloy S is the preferred material. Therefore, based on the results of this study, the general purpose 90 SrF 2 heat source will consist of a standard WESF Hastelloy C-276 inner capsule filled with 90 SrF 2 and a Hastelloy S outer capsule having a 2.375-in. inner diameter and 0.500-in. wall thickness. The end closures for this study, the general purpose 90 SrF 2 heat a Hastelloy S outer capsule having a 2.375-in. inner diameter and 0.500-in. wall thickness. The end closures for the outer capsule will utilize an interlocking joint design requiring a 0.1-in. penetration closure weld

    I do not remember whether I had met Prof. S. S. Chern when he was a graduate student of Tsinghua University in Peking (now Beijing) where my father was a mathematics professor, and I was in elementary school. But I do remember how I had met Mrs. Chern for the first time, in early October, 1929, when I was seven years old and she was in junior high school. Her father, Professor Tsen, had been a professor of Mathematics at Tsinghua University already for a number of years, and the Yangs were new comers that fall. The Tsens invited us to their house for dinner and that was when I first made the acquaintence of "big sister Tsen"...

    Creep and stress rupture properties are determined for the candidate materials to be used in hightemperature gas-cooled reactor (HTGR) components. The materials and test methods are briefly described based on experimental results of test durations of about20000 h. The medium creep strengths of the alloys Inconel-617, Hastelloy-X, Nimonic-86, Hastelloy-S, Manaurite-36X, IN-519, and Incoloy-800H are compared showing that Inconel-617 has the best creep rupture properties in the temperature range above 800 0 C. The rupture time of welded joints is in the lower range of the scatterband of the parent metal. The properties determined in different simulated HTGR atmospheres are within the scatterband of the properties obtained in air. Extrapolation methods are discussed and a modified minimum commitment method is favored

    Outgassing rates of vacuum wall candidate materials; stainless steel SS-304L and YUS-170, Inconel-625 and Hastelloy-X, and first wall materials; molybdenum, pyrolytic graphite and silicon carbide are measured before, during and after a bake-out at 500 0 C. The outgassing rate from the inside wall of the cylinder made of each material is estimated from the pressure difference between before and after a calibrated orifice. The ultimate outgassing rates of SS-304L and pyrolytic graphite, and YUS-170 Inconel-625, Hastelloy-X and molybdenum are the orders of 10 -10 and 10 -11 Pa.l.s -1 cm -2 , respectively

  3. Swelling in neutron irradiated nickel-base alloys

    Brager, H.R.; Bell, W.L.

    1972-01-01

    Inconel 625, Incoloy 800 and Hastelloy X were neutron irradiated at 500 to 700 0 C. It was found that of the three alloys investigated, Inconel 625 offers the greatest swelling resistance. The superior swelling resistance of Inconel 625 relative to that of Hastelloy-X is probably related to differences in the concentrations of the minor rather than major alloy constituents, and can involve (a) enhanced recombination of defects in the Inconel 625 and (b) preferential attraction of vacancies to incoherent precipitates.

    1979-01-01

    In order to estimate the creep and rupture strengths of candidate alloys for the intermediate heat exchanger of VHTR, creep and stress rupture tests in impure helium were conducted on Hastelloy X, Inconel 617, Inconel 625, Incoloy 800 and Incoloy 807 at 900 0 C. The results were discussed in comparison with those in air and the alloys were examined from the point of view of the elevated temperature structural design. The main results obtained are summarized as follows: (1) No appreciable decrease in creep and rupture strengths in helium as compared with those in air is observed on Hastelloy X and Inconel 625. On the contrary, the creep and rupture strengths of Inconel 617 in helium decrease slightly as compared with those in air. In the case of Incoloy 807, the creep strength to cause 1 percent total strain and that to initiate secondary creep increase remarkably in helium as compared with those in air. However, the creep strength to cause initiation of tertiary creep and the rupture strength in helium remarkably decrease as compared with those in air. (2) The order of magnitude of the S 0 value for each material in helium is as follows; Hastelloy X > Inconel 617 > Incoloy 807 > Inconel 625 > Incoloy 800 Meanwhile, that of the S sub(t) value in helium is; Inconel 617 > Hastelloy X > Incoloy 807 > Inconel 625 > Incoloy 800.

  7. Mechanical characterization of superalloys for space reactors

    International Nuclear Information System (INIS)

    Duchesne, J.

    1989-01-01

    The purpose of this work is the choice of materials usable between 600 and 900 0 C for nuclear space reactor structures. The main criterion of selection for these materials is their good creep behaviour. Consequently, macroscopic theories of creep and several extrapolation methods were described. Superalloys seem the best materials for the studied range of temperatures. Five of them, base nickel, ones unusual in nuclear industry were selected for their good mechanical properties. Three of them are industrial alloys: the first, HAYNES 230 is a recent one, HASTELLOY S and X are more standard materials. The last two, HASTELLOY XR and PYRAD 38 D are issued from special fabrications. Creep tests metallographic investigations, hardness and tensile tests were performed. A contraction of samples was observed during some creep tests under a low stress, 20MPa at 800 0 C, for HAYNES 230 and HASTELLOY X. This could be due to a structural evolution of these materials connected to a decrease of the cristalline parameter. In addition, correlations were observed between certain characteristics determined from slow tensile tests and short duration creep tests. These correlations present a large interest because, at the present time, creep tests cannot be executed on irradiated materials in our laboratories. Consequently creep behaviour of irradiated materials seem may be deduced. Further studies are needed to explain and confirm the behaviour of the most interesting materials under low stresses: HAYNES 230 and HASTELLOY XR to anticipate their behaviour in working conditions [fr

    We discuss the results of a study of MgB{sub 2} multifilamentary conductors and coated conductors from the point of view of their future dc and ac applications. The correlation between the slope of the irreversibility line induced by neutron irradiation defects and in situ structural imperfections and the critical temperature and critical current density is discussed with respect to the conductor performance and applicability. We debate the possible origin of the observed anomalous decrease of ac susceptibility at 50 K in copper clad in situ powder-in-tube MgB{sub 2} wires. Different conductor preparation methods and conductor architectures, and attainable critical current densities are presented. Some numerical results on critical currents, thermal stability and ac losses of future MgB{sub 2} multifilamentary and coated conductors with magnetic cladding of their filaments are also discussed.

    The KF - ZrF4 system was considered for the application as a heat exchange agent in molten salt nuclear reactors (MSRs) beginning with the work carried out at ORNL in early fifties. Based on a combination of excellent properties such as thermal conductivity, viscosity in the molten state, and other thermo-physical and rheological properties, it was selected as one of possible candidates for the nuclear reactor secondary heat exchanger loop.

    Full Text Available Wilson’s disease is a autosomal recessive disorder of copper metabolism. Clinical phenotypes include hepatic, haemolytic, neurologic and psychiatric diseases. Wilson’s disease is caused by mutations in the ATP7B gene. ATP7B encodes a hepatic copper-transporting protein, which is important for copper excretion into bile. Neurological symptoms in Wilson’s disease include variable combinations of dysathria, ataxia, parkinsonism, dystonia and tremor. Wilson’s disease is lethal if untreated. This review discusses the epidemiology, genetics, clinical features, etiopathophysiology, diagnostic tests, and treatment of Wilson’s disease

  7. The dS/dS correspondence

    International Nuclear Information System (INIS)

    Alishahiha, M.; Karch, A.; Silverstein, E.; Tong, D.

    2004-07-01

    We present a holographic duality for the de Sitter static patch which consolidates basic features of its geometry and the behavior of gravity and brane probes, valid on timescales short compared to the decay or Poincare recurrence times. Namely de Sitter spacetime dS d (R) in d dimensions with curvature radius R is holographically dual to two conformal field theories on dS d-l (R), cut off at an energy scale 1/R where they couple to each other and to d-1 dimensional gravity. As part of our analysis, we study brane probes in de Sitter and thermal Anti de Sitter spaces, and interpret the terms in the corresponding DBI action via strongly coupled thermal field theory. This provides a dual field theoretic interpretation of the fact that probes take forever to reach a horizon in general relativity. (author)

    We propose a direct test of the existence of gauge duals for nonsupersymmetric asymptotically free gauge theories developing an infrared fixed point by computing the S-parameter in the electric and dual magnetic description. In particular we show that at the lower bound of the conformal window...... the magnetic S-parameter, i.e. the one determined via the dual magnetic gauge theory, assumes a simple expression in terms of the elementary magnetic degrees of freedom. The results further support our recent conjecture of the existence of a universal lower bound on the S parameter and indicates...

  20. Childbirth and Trauma, 1940s-1980s.

    Science.gov (United States)

    Michaels, Paula A

    2018-01-01

    This article analyzes trauma in mid-twentieth century hospital births, focusing on the United States, but with additional evidence drawn from Great Britain and France. As many as half of women today experience childbirth as traumatic and no evidence suggests that the figure was lower a half-century ago. Drawing on women's birth narratives and psychiatric literature, this article highlights the striking consistency over time in how women describe their experiences of traumatic birth. By the 1970s, however, women proved less ready to accept their trauma as the product of their own psychological shortcomings. Under the sway of second-wave feminism, they pushed back against care they defined as inhumane in both conventional maternity care and in natural childbirth. Psychiatry too demonstrates change over time. Hegemonic at midcentury, Freudian thinking began to yield to critiques that questioned gender norms and the preeminence of the subconscious. Based on private letters to maternity caregivers and between physicians, as well as a wide array of medical journal articles, popular magazines, and newsletters from childbirth education and birth advocacy organizations, this article argues that, despite different approaches to trauma in birth and clarity about how best to minimize it, contemporary maternity care has to date proven unable to heed the lessons of history. © The Author 2017.

  1. Surdez súbita

    Maia Roberto Alcantara

    2004-01-01

    Full Text Available A surdez súbita se caracteriza como uma surdez sensorioneural de aparecimento abrupto e sem causa conhecida. Seu acometimento é quase sempre unilateral, sendo acompanhada de zumbidos em aproximadamente 80 por cento dos casos e de tonturas em 30 por cento. O diagnóstico diferencial inclue algumas doenças infecciosas, hematológicas, neurológicas e, principalmente, o schwannoma vestibular. A etiopatogenia da surdez súbita é desconhecida, sendo portanto aventadas algumas hipóteses: a hipótese vascular é muito bem aceita, sendo comprovada em alguns estudos experimentais; a hipótese viral, também bastante reconhecida, tem sérias dificuldades na sua comprovação laboratorial; a hipótese auto-imune, mais recentemente relatada, tem o forte respaldo de estudos imunolaboratoriais a seu favor; finalmente, a hipótese de ruptura de membranas (teoria da fístula vem perdendo terreno em função da sua difícil comprovação. A tendência atual é considerar a surdez súbita como uma afecção de etiopatogenia multifatorial. O tratamento da surdez súbita é o tópico de maior controvérsia. Os corticóides e as drogas vasodilatadoras são as opções mais utilizadas muito em função de sua fácil prescrição associada ao baixo custo. O estudo individualizado de cada caso tende a preconizar diferentes atitudes terapêuticas nos pacientes acometidos pela surdez súbita. Desta forma, diferentes formas de tratamento devem ocupar o espaço dos famosos protocolos de tratamento descritos por inúmeros autores.

    Cécile Laborde’s Liberalism’s Religion proposes liberal principles to address political controversies over religion. One is the public reason requirement that reasons for state policies should be accessible. Another is the civic inclusiveness requirement according to which symbolic religious...... establishment is wrong when it communicates that religious identity is a component of civic identity.

  4. Joyce’s Noises

    Directory of Open Access Journals (Sweden)

    Derek Attridge

    2009-10-01

    Full Text Available James Joyce uses both lexical and nonlexical onomatopoeia extensively in _Ulysses_; this essay examines some of the ways in which he employs the latter in order to convey noises of many kinds. Nonlexical onomatopoeia is particularly suited to the evocation of noise, though it can only do so in conjunction with shared literary and linguistic conventions. Several of the characters in _Ulysses_ show an interest in the representation of noise in language, but there are many more examples where there is no evidence of mental processes at work. The reader’s pleasure in Joyce’s nonlexical onomatopoeia is very seldom the result of vivid imitation; it is, as these examples testify, Joyce’s play with the workings of the device (and frequently its failure to imitate the nonlinguistic world that provides enjoyment and some insight into the relation between language and sound.

    The radionuclei 40 K, 81 Kr, 87 Rb, 93 Zr, 107 Pd, 147 Sm, 176 Lu and 205 Pb are built up totally or partially by the s-process. Due to their long half life they are potential chronometers for the age and the development of the s-process. The usefulness of the various nuclei is discussed. For the determination of the mean age of the s-process synthesis and with it the age of the galaxy, 176 Lu is best suited. It is demonstrated that this age can be calculated solely from measured cross section and abundance ratios. Various effects which can limit the usefulness of 176 Lu as a clock are discussed. (orig.)

    Full Text Available : Hans Sedlmayr exhibited his new theory and methodology of Strukturforschung in his monograph on Francesco Borromini, Die Architektur Borrominis (1930. The book has hardly been read and most attention is placed on its controversial ‘schizothymic’ reading of Borromini’s personality. This study contextualizes the whole book within the larger project of the New Vienna School and clarifies its intent. Noting Sedlmayr’s movement from structure to chains of influence, the architectural historians arrival on personality is clarified as begged by the idiosyncrasies of Borromini’s forms. Sedlmayr rounded out this complete analysis of the architect into a too-neat and abbreviated interpretive package, yet a fresh reading shows its distance from quick characterizations normally found in Anglo-American texts.

    Full Text Available The studies on Witkacy’s oeuvre Narcotics (Narkotyki, 1932 exist without any specific status, as if reduced to a research element ancillary to other “more serious” creative areas of its author. The above is especially astonishing since they belong to a specific literary genre which was started with De Quincy’s Confessions of an Opium Eater (1821 and became really successful in the 19th and 20th centuries, with Baudelaire, Cocteau, Artaud, Huxley and many others. Witkacy was the first Polishwriter who addressed the issue of drug addiction and wrote explicitly on the role of narcotics in artistic creation. He experimented with cocaine, mescaline, peyotl and discovered “the magic peyotl” in the same years as A. Artaud and W. Benjamin, and many years before Huxley. He was also one of the few writers who, after having experimented with drugs, began to deal with the theory of narcotics.The use of opium, cocaine, dawamesk also became a sort of caricatural form in many of his works from Cuttlefish (Mątwa up to the novel The Only Way Out (Jedyne wyjście. The aim of my work is to try to answer several questions: In what way does the author’s interest in the addiction of Unwashed Souls (Niemyte dusze fit into the 19th and 20th century debate between doctors, writers and European artists? Can Witkacy’s literary and dramatic work demonstrate that he was familiar with publications on pharmacology (published in Germany and France in the 20s and also with the authors who were writing about drugs in the 19th and 20th century? How does his prohibitionist point of view fit with his historiosophy? Can Narcotics be considered a literary work? I have also tried to determine the anonymous sources quoted by Witkacy and co-authors of Narcotics, B. Filipowski and S. Glass (pen name of Dezydery Prokopowicz.

    Full Text Available Gaucher′s disease (GD is the most common amongst the various disorders classified under the lysosomal storage disorders. GD is a model for applications of molecular medicine to clinical delineation, diagnosis, and treatment. The multiorgan and varied presentation of the disease makes it a challenge to diagnose GD early. The advent of enzyme replacement therapy in the early 1990s changed the management, and survival, of patients with GD. In addition to this, development of substrate reduction, pharmacological chaperone, and gene therapies has broadened the horizon for this rare disease. However, in resource-poor countries like ours, optimal management is still a distant dream.

Although urethritis was absent, other clinical and histopathological features of the cutaneous lesions led us to the diagnosis. The-possible relationship of postural psoriasis to Reiter′s syndrome is discussed. Failure of the patient to respond satisfactorily to steroids, antibiotics etc, prompted the use of rnethotrexate in the case. The result was dramatic, as the patient completely recovered within ten days of starting treatment.

    2008-01-01

    A minor leak was detected in a drain line for Hood 2B located in the 222-S Laboratory. The line transfers radioactive waste, spent analytical standards, and chemicals used in various analytical procedures. Details are in the report provided by David Comstock, 2B NDE June 2008, work package LAB-WO-07-2012. Including the noted leak, the 222-S Laboratory has experienced two drain line leaks in approximately the last two years of operation. As a consequence, CH2M HILL Hanford Group, Inc. (CH2M HILL) requested the support of ChemMet, Ltd., PC (ChemMet) at the Hanford Site 222-S Laboratory. The corrosion expertise from ChemMet was required prior to preparation of a compatibility assessment for the 222-S Laboratory waste transfer system to assure the expected life of the piping system is extended as much as practicable. The system includes piping within the 222-S Laboratory and the 219-S Waste Storage and Transfer Facility and Operations Process. The ChemMet support was required for an assessment by 222-S staff to analyze what improvements to operational activities may be implemented to extend the tank/piping system life. This assessment will include a summary of the various material types, age, and locations throughout the facility. The assessment will also include a discussion of materials that are safe for drain line disposal on a regular basis, materials that are safe for disposal on a case-by-case basis including specific additional requirements such as flushing, neutralization to a specific pH, and materials prohibited from disposal. The assessment shall include adequate information for 222-S Laboratory personnel to make informed decisions in the future disposal of specific material types by discussing types of compatibility of system materials and potential wastes. The assessment is expected to contain some listing of acceptable waste materials but is not anticipated to be a complete or comprehensive list. Finally the assessment will encompass a brief discussion of

  15. Rutherford’s Legacy

    CERN Multimedia

    2011-01-01

    It’s 100 years to the month since Ernest Rutherford published the paper that established the existence of the atomic nucleus, and in a way gave rise to much of what we do at CERN.   Rutherford’s analysis, based on measurements made by Hans Geiger and Ernest Marsden, established the existence of the atomic nucleus, and with it an understanding that what appears to be solid matter is in fact mostly empty space. As Arthur Eddington put it: “If we eliminated all the unfilled space in a man’s body and collected his protons and electrons into one mass, the man would be reduced to a speck just visible with a magnifying glass.” A sobering thought. Nevertheless, something gives matter substance and that, of course, is the forces that act between the particles in Eddington’s tiny speck. Particle physics is the study of those particles and forces, and CERN has evolved into a world-leading centre for that study. Over the years, a common thread of CE...

    Directory of Open Access Journals (Sweden)

    Ștefan Mera

    2014-11-01

    Full Text Available The term ”Hetimasia” is of Greek origin and its basic meaning is ”preparation. ”Hetimasia’s Throne is an iconographic motif of the Christian art arising in the period of the primary church, approximately during the 4th century; it symbolizes the persons of the Holy Trinity and starting with the 11th century, the throne of the Last Judgment (cf. Ps. 9.7-8; as such, it inherits an eschatological connotation. The term eJtoimasiva is mainly used in the Biblical Greek of the Old Testament - in Septuagint – and in the New Testament, where it is especially employed for the Hebrew verb kun /WB, whose various meanings it assimilates. Hetimasia’s Throne is nothing else than an elongation in history until the end of times, up to the Last Judgment, of Yahweh’s Throne amidst the people of Israel, the idea of an empty throne being taken over by the nations surrounding Israel, and extending on a secular line, as a symbol of the divinely-conferred authority of the king. After the Edict of Milan, in 313, this symbol has been assumed by the liturgical art of early Christianity, Christ being the Emperor and the Lord, true man, but also true God, the inheritor of the Davidic throne, together seated with the Father and the Holy Ghost (cf. Apocalypse 3.21. In the same time, the Holy Fathers assert the sacrificial altar of Christ as Divinity’s true throne, the Holy Table on which the hierarchs and the priests deliver the Liturgies on Sundays and at holy feasts. Even our Mother of God is named throne of the Divinity, because in her Christ was born, and so she becomes the bridge between the presence of Yahweh in the Holy of Holies, in the Old Covenant and the unseen presence of God on the Holy table in the Holy Altar. This is the reason why the Mother of God is presented on the calotte of the Holy Altar; she is the stair on which the divine glory descends and, at the same time, the burning bush which never deliquesces.

    DeVore, J.R.; Haff, K.W.; Tompkins, J.A.

    1986-08-01

    Three 2500-watt (thermal) heat sources were fabricated by the Oak Ridge National Laboratory (ORNL) for the purpose of fueling a 500-watt (electric) thermoelectric generator as part of the US Department of Energy's Byproducts Utilization Program (BUP). Each of the sources, which are the largest ever assembled, consist of hot-pressed pellets of 90 Sr fluoride, doubly encapsulated in three Haynes-25 inner capsules and in a Hastelloy-S outer capsule. The total 90 Sr inventory of all three sources is 1.12 million curies. The sources were fabricated at the ORNL Fission Product Development Laboratory (FPDL), which is a facility that is capable of processing multi-megacurie quantities of radioactive materials, chiefly 137 Cs and 90 Sr. The source was tested to determine compliance with all of the IAEA Safety Series No. 33 requirements. The source fabrication, assembly, and testing are described in the presentation

  18. U.S. gas

    International Nuclear Information System (INIS)

    Parent, L.

    1991-01-01

    This paper reports that U.S. gas producers won't see much price relief in 1991, barring a Persian Gulf war that interrupts crude supply which might be replaced by gas on short notice. Besides the current supply surplus, natural gas futures have added yet another dimension to the process of setting gas prices. Spectators (read speculators) having no intention of ever buying one cu ft of gas now have a hand in setting the forward price of gas. That doesn't necessarily mean something bad; it simply means that there is a new game with new rules and new players. All things considered, look for an average spot price of $1.70 this year. Exploration should pick up modestly, but production from conventional sources is expected to decline slightly in the '90s. Technological developments that enhance deliverability and reduce finding costs will moderate the decline, but not halt it

  19. Hamlet’s Religions

    Directory of Open Access Journals (Sweden)

    Peter Iver Kaufman

    2011-09-01

    Full Text Available Pastoral challenges prompted pietists among Elizabethan Catholics and Calvinists to commend what historians now call an inward turn whereby the faithful, in a sense, become their own confessors. This article suggests that spiritual exercises or soliloquies Shakespeare scripted for his Hamlet (and, less so, for Angelo in Measure for Measure compare favorably with the devotional literature that underscored the importance of self-analysis, intra-psychic conflict, and contrition. The argument here is not that the playwright’s piety resembled his Hamlet’s but that the latter reflected efforts to structure desire in the religions of the time struggling for survival and recognition. References to passages in Shakespeare plays (act, scene appear parenthetically in the text. Unless otherwise indicated in the bibliography appended to this article, all early printed material is accessible at the Early English Books database, http://eebo.chadwyck.com/home, verified June 1, 2011.

    2017-03-01

    Full Text Available Poland’s syndrome is a rare congenital condition classically characterized by partial or complete absence of chest muscles on one side of the body and usually webbing of the fingers of the hand on the same side. There may also be rib (aplasia or hypoplasia and chest bone abnormalities, which may be noticeable due to less fat under the skin. Breast and nipple abnormalities may also occur, and underarm hair is sometimes sparse or abnormally placed. In most cases, the abnormalities in the chest area do not cause health problems or affect movement. Poland’s syndrome most often affects the right side of the body and occurs more frequently in males than in females. The etiology is unknown; however, interruption of the embryonic blood supply to the arteries that lie under the collarbone (subclavian arteries is the prevailing theory. There are many methods of operative correction because of the polymorphic clinical features of this syndrome. We gathered data on the etiology, pathogenesis, and clinical presentation of Poland’s syndrome and reviewed the existing surgical treatment options.

    Full Text Available Sneddon’s syndrome is usually characterized by the association of an ischemic cerebrovascular disease and a widespread livedo reticularis. The incidence of Sneddon syndrome is 4/1000 000. We present 42-year-old woman with livedo reticularis, recurrence ischaemic cerebrovascular accidents, two repetitive miscarriages and positive anti-2GPi antibodies. Skin biopsy specimens reveal inflammatory changes of small- to medium-sized arteries and subendothelial proliferation and fibrosis. The diagnosis Sneddon syndrome is confirmed by skin biopsy, and MR evidence. We suggest that anti-2GPi antibodies may be pathophysiologically related to the clinical manifestation observed in some patients with Sneddon syndrome.

    Witkacy suffered from amusia as a child and as an adult person. He was seriously interested in music only for a little over twenty years (1890–1914?). He wrote his main works as an amusic. The relation between amusia and metaphysical feelings may suggest that Witkacy wrote dramas and created painting compositions in order to evoke the lost strangeness of being. Amusia could have also been the reason for Witkacy’s ambiguity – he was defending and degrading high art at the same time.

  17. Anti-U-like as an alloantibody in S-s-U- and S-s-U+(var) black people.

    Peyrard, Thierry; Lam, Yin; Saison, Carole; Arnaud, Lionel; Babinet, Jérôme; Rouger, Philippe; Bierling, Philippe; Janvier, Daniel

    2012-03-01

    S, s, and U antigens belong to the MNS system. They are carried by glycophorin B (GPB), encoded by GYPB. Black people with the low-prevalence S-s- phenotype, either U- or U+(var), can make a clinically significant anti-U. Anti-U-like, a cold immunoglobulin G autoantibody quite commonly observed in S-s+U+ black persons, was previously described to be nonreactive with ficin-, α-chymotrypsin-, and pronase-treated red blood cells (RBCs); nonreactive or weakly reactive with papain-treated RBCs; and reactive with trypsin-treated RBCs. Here we describe, in S-s- people from different molecular backgrounds, an alloantibody to a high-prevalence GPB antigen, which presents the same pattern of reactivity with proteases as autoanti-U-like. Four S-s- patients with an alloantibody to a high-prevalence GPB antigen were investigated by serologic and molecular methods. An alloantibody was observed in two S-s-U-/Del GYPB, one S-s-U+(var)/GYPB(P2), and one S-s-U+(var)/GYPB(NY) patients. As this alloantibody showed the same pattern of reactivity with proteases as autoanti-U-like, we decided to name it "anti-U-like." Anti-U-like made by the two S-s-U- patients was reactive with the S-s-U+(var) RBCs of the two other patients. S-s-U-/Del GYPB, S-s-U+(var)/GYPB(P2), and S-s-U+(var)/GYPB(NY) patients can make an alloanti-U-like. Anti-U-like made by S-s-U- people appears reactive with GYPB(P2) and GYPB(NY) RBCs, which both express a weak and partial U-like reactivity. We recommend transfusing S-s-U- RBCs in S-s-U- patients showing alloanti-U-like. Our study contributes to a better understanding of alloimmunization to GPB in black people and confirms importance of genotyping in S-s- patients, especially those with sickle cell disease to be frequently transfused. © 2011 American Association of Blood Banks.

    2018-01-01

    Full Text Available History of present illness: A 30-year-old African American male presents with two days of gradually worsening vesicular pruritic rash over the left naris, left upper lip, and inferior to medial epicanthus, initially noted just on the upper lip the night before. By the next day it had spread to the nose and cheek. Patient denies any fever, pain, discharge from the rash, ear or nose, or changes in vision. He denies exposure to any new hygiene products, household cleaning products, recent outdoor activities, travel, or insect bites. Past medical history significant for a childhood varicella infection. Patient works for a moving company, and had an episode of heat exhaustion at work one week prior to onset. Denies alcohol or drug abuse. Significant findings: The unilateral distribution of vesicular lesions over the patient’s left naris, cheek, and upper lip are consistent with Herpes zoster reactivation with Hutchinson’s sign. Hutchinson’s sign is a herpes zoster vesicle present on the tip or side of the nose.1 It reflects zoster involvement of the 1st branch of the trigeminal nerve, and is concerning for herpes zoster ophthalmicus.1 Herpes zoster vesicles may present as papular lesions or macular vesicles on an erythematous base.2,3 Emergent diagnosis must be made to prevent long-term visual sequelae.4 Discussion: The history of a childhood viral exanthem, specifically a past varicella infection, helps direct the diagnosis.2 Herpes zoster ophthalmicus is an ophthalmological emergency and results from viral reactivation within the V1 branch of CN V, leading to direct ocular involvement.1 Symptoms of ocular involvement include red eye, blurry vision, eye pain or photophobia.1 If left untreated, corneal ulceration, scarring, perforation, glaucoma, cataracts, and blindness may occur.1 Fluorescein staining with slit lamp examination will show a characteristic “dendritic ulcer” within the epithelial layer of the cornea.1 Treatment is generally

    Full Text Available A 28-year-old male patient, presented with a one-week history of pain and itching on the skin of the left upper leg. Erythematous indurated, warm and painful on palpation, subcutaneous plaques and nodules were clinically observed, affecting the skin of the left upper leg, within a recent black-wolf tattoo. The diagnosis of traumatic panniculitis with superposed bacterial infection, provoked by a wolf tattoo was made.  The patient underwent 7-days systemic antibiotic treatment regimen and topical application of iodine povidone unguent under occlusion for 7 days. Significant alleviation of the subjective complaints was achieved within the first week, with a total clinical resolution of the symptoms. The role of the procedure as a source of trauma for subcutaneous inflammation (traumatic panniculitis and the contamination of the equipment or the staff (infective panniculitis in simultaneously triggering of the pathogenetic chain of the reported Wolf’s panniculitis could be present.

    Full Text Available What keeps us from becoming what we can be? Renaissance genius Michelangelo’s ideas about crafting sculpture are a powerful metaphor for the release of our hidden performance potential. The actualizations of inherent potential can be viewed as a creative work performance that synergizes head, heart, and body. Potential is seen as being closely related to the psychological concepts of talents and multiple intelligences.   For the global economy, the effective employment of talent, intelligence, and knowledge is projected to be a primary driving force for years to come. For business organizations, investment in the realization of human potential is seen to have lasting value and is considered to be a continuing source of competitive advantage. For the Arts and Humanities, the constructive realization of human potential has been a long-pursued Holy Grail. And, for the individual, there is the real possibility of enhanced future performance with an associated economic payoff.

    Full Text Available Raynaud’s phenomenon (RP is a vasospastic disorder characterized by episodic color changes of blanching, cyanosis, and hyperemia in response to cold and/or emotional stress. Although most typically noted in the fingers, the circulation of the toes, ears, nose and tongue is also frequently affected. Population studies have shown that RP in adults is more common in women than men, with prevalence estimates ranging from 4% to 30%. Geographic variations in the prevalence reflect differences in climate. RP may be a primary or a secondary process. LeRoy and Medsger suggested criteria for primary RP: symmetric attacks, the absence of tissue necrosis, ulceration or gangrene, the absence of a secondary cause, negative antinuclear antibodies, normal nailfold capillaroscopy and a normal erythrocyte sedimentation rate. Secondary RP is characterized by an age of onset of more than 30 years, painful and asymmetric attacks, ischemic skin lesions, positive autoautoantibodies, capillaroscopic abnormalities and/or clinical features suggestive of connective tissue diseases (CTDs. Among the CTDs, systemic sclerosis has the highest frequency of RP. Finding a cause for RP requires a knowledge of the patient’s occupational, smoking, drug history, physical examination, nailfold capillaroscopy, routine laboratory tests and autoantibodies. Furthermore, RP should be distinguished from acrocyanosis, a condition characterized by continuous cyanosis of the hands or feet that is aggravated by cold temperature. The most important instruction to the patient is abstinence from any smoking, offending drugs should be discontinued, and abrupt changes in temperature. If these measures are inadequate, calcium-channel blockers are the most widely used (nifedipine 30 mg up to 90 mg daily. Alternatively, sympatholytic agent (prazosin, angiotensin II -receptor type I antagonist (losartan, selective sertonin-reuptake inhibitor (fluoxetine may be useful. In the severe cases the role of

  3. U. S. Mirror Program

    Fowler, T.K.

    1978-01-01

    The mirror approach is now the principal alternate to the tokamak in the U.S. magnetic fusion energy program. The program is now focused on two new concepts that can obtain high values of Q, defined as the ratio of fusion power output to the neutral beam power injected to sustain the reaction. These are the tandem mirror and field reversed mirror concepts. Theoretically both concepts should be able to attain Q = 5 or more, as compared with Q approximately 1 in previous mirror designs. Success with either or both of these approaches would point the way toward fusion power plants with many attractive features. The linear geometry of mirror systems offers a distinct alternative to the toroidal tokamak. As a direct consequence of this difference in geometry, it is generally possible to build mirror systems in smaller units of modular construction that can probably be made to operate in steady-state. During the next 5 years the main mirror facilities in the U.S. will be the 2XIIB (renamed Beta II); a tandem mirror experiment caled TMX; and the Mirror Fusion Test Facility (MFTF) scheduled to be completed in 1981 at a cost of $94 million. As a background for discussing this program and mirror reactor concepts in later lectures, the current status of mirror physics will be reviewed by comparing theory and experimental data in four critical areas. These are adiabatic confinement of individual ions, electron heat losses out of the ends of the machine, the achievement of beta values of order unity; and stabilization of ''loss cone'' modes

    1997-01-01

    The S = -1 and S = -2 few-body bound states are the focus of this discussion. Implications for the understanding of the baryon-baryon interaction are examined. Octet-octet coupling effects not found in conventional, non-strange nuclei are highlighted. TJNAF wave function tests for the S = -1 sector are noted. The need to identify S = -2 hypernuclei to explore the S = -2 strong interaction and to test model predictions is emphasized

    Tensile fatigue tests were carried out at 77 K for YBCO-coated conductors fabricated by metal-organic chemical vapor deposition (MOCVD). The S-N relationship, variation of critical current (I c ) during cyclic loading and microscopic fatigue damage were investigated. Fatigue strength at 10 6 cycles was evaluated to be σ max = 1300 MPa and 890 MPa under the stress ratios of 0.5 and 0.1. Two different mechanisms of fatigue damage, depending on the number of stress cycles to failure, were observed. In one of the fracture mechanisms, fatigue behavior is characterized by overall fracture which occurs at 10 4 -10 5 cycles. For these specimens, I c after unloading does not degrade before overall fracture. Although only shallow slip bands were found at the Ag surface, fatigue cracks were found on the Hastelloy C-276 surface of the fractured specimen. These results suggest that overall fracture due to cyclic stress was caused by fatigue of the Hastelloy substrate. In the other fracture mechanism, even though overall fracture did not occur at 10 6 cycles, a slight decrease of I c was detected after 10 5 cycles. No fatigue crack was found on the Hastelloy surface, while deep slip bands corresponding to the initial stage of fatigue crack were observed on the Ag surface. From these results, we concluded that I c degradation at a high cycle number is attributed to the fatigue of the Ag stabilizing layer

    Similarity between Newtonian gravitational force and Coulomb’s force leads one to define gravitational electric and magnetic fields or gravito-electromagnetic fields. Also, one may define a gravitational Bohr’s theory in analogy with the electromagnetic Bohr’s theory for which the latter is quite successful in explaining some properties of hydrogen atom. Unlike to the Coulomb’s force, the Newton‘s force is believed to be an approximated theory of gravity as it is unable to explain the Mercury’s orbit. This paper discusses the gravitational Bohr’s theory by taking into account the Newton’s potential and Weber’s potential; the later is a modified Newton’s gravitational potential that conforms, to some degrees, to the anomaly of the Mercury’s orbit.

    Full Text Available Gilbert\\'s syndrome (GS is a benign condition that does not progress to chronic liver disease or fibrosis. GS diagnosis should be considered in patients with chronic elevation of unconjugated bilirubin. In these patients the presence of hemolysis and other diseases of the liver should be excluded. GS is an autosomal recessive disease. The mutation of UDP-glucuronyl transferase is seen in 10-16% of the population. There is a 70-80% decrease in bilirubin glucuronidation. In cases of unexplained indirect hyperbilirubinemia with no history of drugs, smoking or alcohol use, GS should be considered. Firstly, hemolysis should be excluded. It has been reported that having increased levels of indirect bilirubin lowers the incidence of carotid plaque and coronary artery disease in patients of GS. The antioxidation and resistance to oxidative stress status of patients with GS is known to be high. However, GS is associated with breast and colon cancer. Several studies have reported that liver transplantation from a patient with GS had no harm to himself or to the recipient. An exact relationship between schizophrenia and GS has not been demonstrated. GS patients have a risk of breast and colon cancer so frequent follow up may be recommended.

  10. Angelina′s choice

    Full Text Available This is an opinion piece on how a celebrity′s personal choice to undergo prophylactic mastectomy on discovery of an aberrant gene, when publicly promoted, carries in itself the power to influence and impact healthcare trends and decisions. When celebrities advocate causes that are universally and uniformly acceptable and indisputable as the best in the realm of healthcare and cure (e.g. no smoking, it creates well-being and awareness in society at large. But those which are personal choices made out of a repertoire of other available and effective options may, because of celebrity preference, don the mantle of a norm. They thus run the danger of being blindly replicated by others without proper awareness and knowledge of the true potential of disease, risk factors, and other existing remedial or risk-reducing measures. Society should thus be encouraged to question, debate, and understand the validity, authenticity, and reason of the choices, especially those with a medical basis. This tempering of information with intelligence and rationale and making informed choices based on facts will serve humanity as a whole.

  12. Szeemann’s tableau

    Oriol Fontdevila

    2017-06-01

    Full Text Available The demystification of the concepts of art and authorship that conceptual art brought about is closely related to the emergence, at the time, of new agents in the field of arts who adopted an authorial function. This is the c ase of the so-called curator-author. As Harald Szeemann foreshadowed in 1969, the idea was born scarcely two years after Roland Barthes suggested “the death of the author”. Szeemann’s Tableau hypothesizes the possibility of a direct connection between both events, while it also traces the exchanges that took place between art and mediation under the influence of post-minimalism and the dawn of Post-Fordism. This article also explores the attempts made by Seth Siegelaub and Lucy Lippardin with regards to exhibiting methodologies, amplifying the deconstructionist echo of conceptual art rather than retracting it into author positions. Finally, the text analyzes the outstanding role of the publications issued during an especially fruitful time in art-mediation.

  13. Derrida’s methodology

    Full Text Available In this paper, I will be discussing Derrida’s reworking of metaphysics as history. Derrida describes history as the history of the metaphysical concept, where ontology delineated a strict division of the signified and the signifier, whereby the signified designated full presence to the signifier, which brings about a certain logocentrism. What this paper has done is show through Derrida that the signified is nothing outside the signifier and that it has to be relayed through time, history, and differance. This is a democratic move as it opens up possibilities for reading. By suggesting that meaning is not ossified and is not to be located outside the text but within the text, Derrida democratizes reading by suggesting that reading is an act of invention and that the possibilities for different readings are endless, where representation would hold you to an objective truth. This paper has shown that this history of the metaphysical concept as we know it, with transcendental and empirical strictly delineated and divided, has come to an end as there never has been anything but writing, meaning is located within the text rather than without, and the reader actively invents his reading instead of simply discovering an objective transcendental signified.

    2016-06-01

    Full Text Available This paper aims at presenting a reconstruction of the main theses of Lambert’s thought and their role in the establishment of Kant’s theoretical philosophy. In order to do so, the paper is divided into three sections. Initially, a consideration of Lambert’s attempt to assure illusion (Schein within the domain of phenomenology (Körperwelt and to institute the domain of metaphysical truth (Intellectualwelt is carried out. Secondly, Kant’s first step away from Lambert’s proposal, which is presented in the Inaugural Dissertation’s thesis that the sensible and intellectual domains of knowledge are grounded upon two distinct and intransmutable faculties, is taken into account. Finally, Kant’s definitive step away from Lambert’s proposal, i.e., the justification of appearances in the Duisburg Nachlaβ in an objective and non-illusory domain, due to the determination of the faculty of understanding, is pointed out.

    Motivated by the work of Bowick and Rajeev, we calculate the curvature of the infinite-dimensional flag manifolds Diff(S 1 )/S 1 and Super Diff(S 1 )/S 1 using standard finite-dimensional coset space techniques. We regularize the infinite by ζ-function regularization and recover the conformal and superconformal anomalies respectively for a specific choice of the torsion. (orig.)

    What is intriguing about women’s football as a cultural phenomenon is that unlike men’s football the finances and media interest for the game are sparse. Nevertheless we have found that migration of female football players is growing steadily and women’s football is becoming global in nature....... The question is then what drives this globalization process? According to our study of women’s football migration into Scandinavia, one of the centers of women’s football, transnational networks play a crucial role in mobilizing global migratory moves. Using the concept of friends-of-friends networks from Bale...

    2017-01-01

    Full Text Available The effect of Debye plasma on the 1 s 2 s 2 2 S resonance states in the scattering of electron from helium atom has been investigated within the framework of the stabilization method. The interactions among the charged particles in Debye plasma have been modelled by Debye–Huckel potential. The 1 s 2 s excited state of the helium atom has been treated as consisting of a H e + ionic core plus an electron moving around. The interaction between the core and the electron has then been modelled by a model potential. It has been found that the background plasma environment significantly affects the resonance states. To the best of our knowledge, such an investigation of 1 s 2 s 2 2 S resonance states of the electron–helium system embedded in Debye plasma environment is the first reported in the literature.

    2008-10-01

    We analyse a recently constructed class of local solutions of type IIB supergravity that consist of a warped product of AdS 3 with a sevendimensional internal space. In one duality frame the only other nonvanishing fields are the NS three-form and the dilaton. We analyse in detail how these local solutions can be extended to globally well-defined solutions of type IIB string theory, with the internal space having topology S 3 x S 3 x S 1 and with properly quantised three-form flux. We show that many of the dual (0,2) SCFTs are exactly marginal deformations of the (0,2) SCFTs whose holographic duals are warped products of AdS 3 with seven-dimensional manifolds of topology S 3 x S 2 x T 2 .

    2015-01-01

    Full Text Available Instruments applying the IACT method, such as H.E.S.S. (High Energy Stereoscopic System, observe VHE (very high energy, E > 100 GeV photons indirectly, using the Earth's atmosphere as a calorimeter. In the H.E.S.S. data reconstruction, the properties of this component are estimated by Monte Carlo simulations of a yearly averaged atmosphere density profile. Deviations of the real atmospheric conditions from this assumed atmospheric model will result in a biased reconstruction of the primary gamma-ray energy and thus the resulting source spectrum. In order to keep the corresponding systematic effects to a minimum, H.E.S.S. operates a set of atmospheric monitoring devices that allows it to characterise the atmospheric conditions during data taking. This information in turn is then used in data selection. Here, a short overview with respect to their usage during source observation and a posteriori analysis data selection will be presented.

  15. The elusive 2s3s1S level in B II

    Martinson, I; Awaya, Y; Ekberg, J O; Kink, I; Mannervik, S; Ryabtsev, A N

    2003-01-01

    It has been known for nearly 30 years that the theoretical and experimental values for the energy of the 2s3s 1 S level in singly ionized boron, B II, differ strongly. Since there is much better agreement for other B II levels, it has been concluded that the experimental value for 2s3s 1 S must be revised. Despite a number of recordings over the years of sliding-spark, hollow cathode and beam-foil spectra, this level has not been located. We have now performed another beam-foil experiment, using higher resolution and sensitivity than in most previous studies. By combining these new data with previous results, we have identified transitions from the 2s4p, 2s5p and 2p3s 1 P levels to 2s3s 1 S, the excitation energy (137 622 ± 3 cm -1 ) of which is now well established and in excellent agreement with theoretical predictions

    In eukaryotes, three of the four ribosomal RNAs (rRNAs)—the 5.8S, 18S, and 25S/28S rRNAs—are processed from a single pre-rRNA transcript and assembled into ribosomes. The fourth rRNA, the 5S rRNA, is transcribed by RNA polymerase III and is assembled into the 5S ribonucleoprotein particle (RNP), containing ribosomal proteins Rpl5/uL18 and Rpl11/uL5, prior to its incorporation into preribosomes. In mammals, the 5S RNP is also a central regulator of the homeostasis of the tumor suppressor p53. The nucleolar localization of the 5S RNP and its assembly into preribosomes are performed by a specialized complex composed of Rpf2 and Rrs1 in yeast or Bxdc1 and hRrs1 in humans. Here we report the structural and functional characterization of the Rpf2-Rrs1 complex alone, in complex with the 5S RNA, and within pre-60S ribosomes. We show that the Rpf2-Rrs1 complex contains a specialized 5S RNA E-loop-binding module, contacts the Rpl5 protein, and also contacts the ribosome assembly factor Rsa4 and the 25S RNA. We propose that the Rpf2-Rrs1 complex establishes a network of interactions that guide the incorporation of the 5S RNP in preribosomes in the initial conformation prior to its rotation to form the central protuberance found in the mature large ribosomal subunit. © 2015 Madru et al.; Published by Cold Spring Harbor Laboratory Press.

  17. The AdS5xS5 superstring worldsheet S matrix and crossing symmetry

    International Nuclear Information System (INIS)

    Janik, Romuald A.

    2006-01-01

    An S matrix satisfying the Yang-Baxter equation with symmetries relevant to the AdS 5 xS 5 superstring recently has been determined up to an unknown scalar factor. Such scalar factors are typically fixed using crossing relations; however, due to the lack of conventional relativistic invariance, in this case its determination remained an open problem. In this paper we propose an algebraic way to implement crossing relations for the AdS 5 xS 5 superstring worldsheet S matrix. We base our construction on a Hopf-algebraic formulation of crossing in terms of the antipode and introduce generalized rapidities living on the universal cover of the parameter space which is constructed through an auxillary, coupling-constant dependent, elliptic curve. We determine the crossing transformation and write functional equations for the scalar factor of the S matrix in the generalized rapidity plane

  2. Einstein’s physical chronogeometry

    Directory of Open Access Journals (Sweden)

    Mario Bacelar Valente

    Full Text Available ABSTRACT In Einstein’s physical geometry, the geometry of space and the uniformity of time are taken to be non-conventional. However, due to the stipulation of the isotropy of the one-way speed of light in the synchronization of clocks (or definition of simultaneity, as it stands, Einstein’s views do not seem to apply to the whole of the Minkowski space-time. In this work we will see how Einstein’s views can be applied to the Minkowski space-time. In this way, when adopting Einstein’s views, chronogeometry is a physical chronogeometry.

    Full Text Available The present work is intended to be an introduction to the Superposition Theory of David Carfì. In particular I shall depict the meaning of his brand new theory, on the one hand in an informal fashion and on the other hand by giving a formal approach of the algebraic structure of the theory: the S-linear algebra. This kind of structure underpins the notion of S-spaces (or Carfì-spaces by defining both its properties and its nature. Thus I shall define the S-triple as the fundamental principle upon which the S-linear algebra is built up.

    We generalize the geometric approach of Bowick and Rajeev [BR] to superstring field theories. The anomaly is identified with nonvanishing of the Ricci curvature of the super-flag manifold. We explicitly calculate the curvatures of superdiff S 1 /S 1 and superdiff S 1 /superS 1 using super-Toeplitz operator techniques. No regularization is needed in this formalism. The critical dimension D=10 is rediscovered as a result of vanishing curvature of the product bundle over the super-flag manifold. (orig.)

    The successful preparation of a macroscopic sample of enriched 33 S by laser-induced molecular dissociation is reported. Approach was to induce isotopically selective dissociation of SF 6 with CO 2 -laser pulses and to separate the remaining SF 6 from the sulfur-containing reaction products by cryogenic distillation. A 200 Hz, 0.75 J/pulse laser was used for photolysis of low-pressure (less than 1 torr) gas mixtures. The mixture of SF 6 and scavenger recirculated continuously throughout the irradiation chamber where the laser pulses selectively dissociated 32 SF 6 to give the final products: SF 4 or SOF 2 . The unreacted SF 6 was enriched in the heavier isotopes: 33 S, 34 S, and 36 S. A 1.3-g sample of SF 6 was collected with a 33 S enrichment factor of 1.96 and a 34 S enrichment factor of 2.25. A similar size sample of depleted ( 32 S) sulfur compounds was also collected. A scavenger was necessary to ensure high yield, and moist hydrogen was found to be best for our conditions. Removal of hydrogen fluoride was also necessary to prevent severe corrosion and to maintain high isotopic selectivity. 6 figures

    The results of a colorimetric investigation of the diffuse nebulas S 156, S 157A, S 158, and NGC 7635, which are excited by O stars, are presented. The nebulas S 156, S 157A, and NGC 7635 are very bright in U due to the presence in them of strong ultraviolet doublet forbidden O II 3727 A. These values correspond effectively to the monochromatic image of the nebulas at this wavelength. The measurements show that the B-V color index does not change significantly with distance from the star except for S 158, where a weak dependence is observed. The results indicate that the physical properties of these nebulas differ little. It is concluded that the gas masses in this association are remnants of star formation that have a common origin with the stars. The age of the association is estimated at 100,000-1,000,000 yr. 13 references

    The decay of a $B_{s}^{0}$ meson to two oppositely charged $D_{s}$ mesons is one that is postulated to be almost exclusively CP even. Measuring the properties of this decay can therefore give important information about the behaviour of the $B_{s}^{0}$ system. This poster presents two of these measurements, made by LHCb, using data from run 1 of the LHC.

    Full Text Available Krinovskii was a preacher in the court of the empress Elizabeth and a member of the Synod. A hundred of his sermons have been published four times in A collection of various instructive talks. In his sermons, Krinowskii spoke about the providence of God and the necessity of the full awareness of God’s presence in everyone’s life. To assure the benevolent presence of God, one’s life has to be pure and modelled after Christ. The life led by God’s precepts will ensure happiness on earth and in the afterlife. Krinovskii’s salvific and moral message was mostly ecumenical, but his sermons are not free from exaggerated praises of the empress and of the role of Russia and Orthodoxy.

  2. Mass loss from S stars

    Jura, M.

    1988-01-01

    The mass-loss process in S stars is studied using 65 S stars from the listing of Wing and Yorka (1977). The role of pulsations in the mass-loss process is examined. It is detected that stars with larger mass-loss rates have a greater amplitude of pulsations. The dust-to-gas ratio for the S stars is estimated as 0.002 and the average mass-loss rate is about 6 x 10 to the -8th solar masses/yr. Some of the properties of the S stars, such as scale height, surface density, and lifetime, are measured. It is determined that scale height is 200 pc; the total duration of the S star phase is greater than or equal to 30,000 yr; and the stars inject 3 x 10 to the -6th solar masses/sq kpc yr into the interstellar medium. 46 references

    This paper reports that while Mexico's petrochemical industry has grown rapidly, it now faces shortages both in investment funds and in supplies of basic petrochemicals due to a financial crisis in the 1980s. Mexico has undertaken a series of policy reforms aimed at encouraging foreign and private investment, but these efforts have generally failed to entice U.S. investment in Mexico. U.S. petrochemical companies have cited unfavorable market conditions, insufficient basic petrochemical capacity in Mexico, concern about the reversibility of Mexican reforms, inadequate Mexican protection of intellectual property rights, and lack of investment protection for U.S. businesses as impediments to investment in Mexico. Cooperation between the two nations in overcoming these obstacles could help U.S. petrochemical companies maintain their positions in a competitive global market, while at the same time provide Mexico with much needed capital investment and technological expertise

    Einstein’s theory of relativity proven wrong, time travel finally possible, all our knowledge suddenly forced to change: superluminal neutrinos have triggered reactions from around the world. While the buzz spread, the theory community was following the usual scientific procedure, which implies understanding, thinking, reading, imagining, monitoring, reviewing and wondering: how could any theory account for OPERA’s result?   Last week, CERN theorists organised a workshop to discuss OPERA’s recent result. The workshop took place the whole morning of Friday 14 October and saw fruitful discussions among theorists, experimentalists, members of the OPERA Collaboration and members of the CERN community at large. The hot topic : assuming that OPERA’s result is confirmed by other experiments, is there any theory that could “accommodate” it? “We have reviewed a large part of the articles published in arXiv after OPERA made its result p...

  13. Study of the s - s bar asymmetry in the proton

    2018-05-01

    The study of s - s bar asymmetry is essential to better understand of the structure of nucleon and also the perturbative and nonperturbative mechanisms for sea quark generation. Actually, the nature and dynamical origins of this asymmetry have always been an interesting subject to research both experimentally and theoretically. One of the most powerful models can lead to s - s bar asymmetry is the meson-baryon model (MBM). In this work, using a simplified configuration of this model suggested by Pumplin, we calculate the s - s bar asymmetry for different values of cutoff parameter Λ, to study the dependence of model to this parameter and also to estimate the theoretical uncertainty imposed on the results due to its uncertainty. Then, we study the evolution of distributions obtained both at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) using different evolution schemes. It is shown that the evolution of the intrinsic quark distributions from a low initial scale, as suggested by Chang and Pang, is not a good choice at NNLO using variable flavor number scheme (VFNS).

    The High Energy Stereoscopic System (H.E.S.S.) is an array of five Imaging Atmospheric Cherenkov Telescopes located in the Khomas Highland in Namibia. It measures cosmic gamma-rays with very high energies (> 100 GeV) using the Earth's atmosphere as a calorimeter. The H.E.S.S. experiment has entered Phase II in September 2012 with the inauguration of a fifth telescope that is larger and more complex than the other four. The very large mirror area of 600 m(2) in comparison to the 100 m(2) of the smaller telescopes results in a lower energy threshold as well as an increased overall sensitivity of the system. Moreover, the huge effective area, due to the large mirror size, is crucial in the detection of short time scale low energy transient events. This paper will give a brief overview of the design principles of the current H.E.S.S. data acquisition and array control system. Particular emphasis is given to the new Target of Opportunity alert system that has recently been introduced to the array and allows the in...

    We derive explicit expressions for the Wigner function of wave functions in D dimensions which depend on the hyperradius--that is, of s waves. They are based either on the position or the momentum representation of the s wave. The corresponding Wigner function depends on three variables: the absolute value of the D-dimensional position and momentum vectors and the angle between them. We illustrate these expressions by calculating and discussing the Wigner functions of an elementary s wave and the energy eigenfunction of a free particle

The test procedure followed closely a predetermined work plan designed to test five different zirconia based materials and the cathode and anode electrode wall modules under MHD operating conditions. The materials which were selected were 88Zr0/sub 2/-12Y/sub 2/0/sub 3/, 82Zr0/sub 2/-18Ce02, 50Zr0/sub 2/-50Ce0/sub 2/, 25Zr0/sub 2/-75Ce0/sub 2/ and 20Zr0/sub 2/-78Ce0/sub 2/-2Ta/sub 2/0/sub 5/. The electrode modules were constructed by Westinghouse Research and Development Laboratory. Each of the five electrode materials had four different current densities established between the anode and cathode during the experiment which lasted a total of 127 hours. There were four main phases in the test schedule: (1) start-up of the channel over a specific heating period. No seed (K/sub 2/C0/sub 3/) introduction - 18 hours. (2) Electrical tests at operating temperature to investigate electro-physical characteristics of the channel and electrodes - 6 hours. (3) Operating life test - 94 hours. (4) Shut-down of the channel over a specific cool down period - 9 hours. All except six electrode pairs performed satisfactorily during the entire test. These were the pairs which were designated to carry maximum or near maximum current density. Five pairs failed early in the life test and the sixth pair failed in the last several hours. Failure was not due to the electrode materials, however, but due to lead-out melting caused by joule heating in the platinum wires. The U-02 facility is described and the operational parameters are given for each phase of the test. The electrode and insulating walls are described and the appropriate parameters that are used to predict the performance of the module are given.

  4. S-matrices and integrability

    International Nuclear Information System (INIS)

    Bombardelli, Diego

    2016-01-01

    In these notes we review the S-matrix theory in (1+1)-dimensional integrable models, focusing mainly on the relativistic case. Once the main definitions and physical properties are introduced, we discuss the factorization of scattering processes due to integrability. We then focus on the analytic properties of the two-particle scattering amplitude and illustrate the derivation of the S-matrices for all the possible bound states using the so-called bootstrap principle. General algebraic structures underlying the S-matrix theory and its relation with the form factors axioms are briefly mentioned. Finally, we discuss the S-matrices of sine-Gordon and SU (2), SU (3) chiral Gross–Neveu models. (topical review)

    Full Text Available Frederick Taylor is known as the father of modern management. Taylor’s scientific management revolutionized industry and helped shape modern organization. Scientific management revolutionized industry because it explains how to increase production by working smarter, not harder. Taylor’s ideas were not limited to only serving the company’s bottom line but the increase in productivity benefited the workforce as well. The principles of scientific management became a machine of universal efficiency since there was a widespread use of scientific management worldwide and beyond the scope of the workplace. Taylor’s theories on using science and statistical fact have become a guideline that many have followed to great success.

  7. Germany’s New Ostpolitik

    Directory of Open Access Journals (Sweden)

    Doctorow Gilbert

    2016-01-01

    Full Text Available A survey of perceptions of Germany’s new Ostpolitik in Russia, the United States and Germany. The author argues that Germany’s abandonment of its strategic alliance with Russia by assuming the lead on sanctions within the EU has not received due attention of experts because it is not supported by any doctrine within Germany itself. The new Ostpolitik is the product of many small steps. It is the consequence of Germany’s uncritical acceptance of democracy promotion as the guideline to foreign policy coming from Brussels and of Berlin’s political accommodation with its neighborhood, the new EU Member States to the East, bringing their revanchism and hostility to Russia into the EU institutions that Germany controls.

    The first measurement of the effective lifetime of the $\\bar{B}_s^0$ meson in the decay $\\bar{B}_s^0\\to D_s^-D_s^+$ is reported using a proton-proton collision dataset, corresponding to an integrated luminosity of 3 fb$^{-1}$, collected by the LHCb experiment. The measured value of the $\\bar{B}_s^0\\to D_s^-D_s^+$ effective lifetime is $1.379\\pm0.026\\pm0.017$ ps, where the uncertainties are statistical and systematic, respectively. This lifetime translates into a measurement of the decay width of the light $\\bar{B}_s^0$ mass eigenstate of $\\Gamma_L = 0.725 \\pm 0.014 \\pm 0.009$ ps$^{-1}$. The $\\bar{B}_s^0$ lifetime is also measured using the flavor-specific $\\bar{B}_s^0\\to D^-D_s^+$ decay to be $1.52\\pm 0.15 \\pm 0.01~{\\rm ps}$.

  20. Monarto’s Contested Landscape

    Directory of Open Access Journals (Sweden)

    Paul Walker

    2015-11-01

    Full Text Available The proposal to develop a new city at Monarto in South Australia during the 1970s was an important project of the reforming government of Don Dunstan. Dunstan’s view was that Monarto would be a city environmentally suited to the tough conditions of its site, and to an ‘Australian way of life’. As planning and preliminary design proceeded from 1972 to 1975, the landscape potential of the city’s selected site became central to its conception. This paper draws on new research comprising interviews with key participants and archival material to examine four issues: the adoption of an environmental orientation in Australian urban planning and discourse in the 1970s; strategies in the design proposals that seemingly gave Monarto validity even as the demographic and political drivers for it dissolved away; the investigations that supported Monarto’s landscape strategies; and attitudes to social and cultural history that the Monarto project adopted. While ultimately the plan for Monarto was abandoned, the projected city’s landscape can be seen as a theatre for competing values in relation to natural and cultural heritage and design ambitions. The paper situates Monarto within national and international urban discourse that is more complex than has been previously acknowledged, indicative of competing values and ideologies in the planning, landscape and design discourses of the period.

    The northern Benguela ecosystem has been overfished and physically challenged over the past three decades. Ecopath with Ecosim was used to construct three ecosystem models (1971-1977, 1980-1989, and 1990-1995) and to compare differences in ecosystem structure. In the 1970s, the system sustained...... existence. The importance of ecosystem-environmental interactions are highlighted by the abundance of horse mackerel, mesopelagics, small pelagics, and hake in the 1980s and the reduced biomass of most species in the 1990s, not only due to overfishing, but also due to the Benguela Nino that occurred in 1995...

Applying Babenko’s approach and fractional integrals, we provide a general method for solving Abel’s integral equation and others with a demonstration of different types of examples by showing convergence of series. In particular, we extend this equation to a distributional space for any arbitrary α ∈ R by fractional operations of generalized functions for the first time and obtain several new and interesting results that cannot be realized in the classical sense or by the Laplace transform.

    Full Text Available Highly ordered mesoporous TiO2 modified by CdS, CdSe, and ZnS quantum dots (QDs was fabricated by successive ionic layer adsorption and reaction (SILAR method. The quantity of material deposition seems to be affected not only by the employed deposition method but also and mainly by the nature of the underlying layer. The CdS, CdSe, and ZnS QDs modification expands the photoresponse range of mesoporous TiO2 from ultraviolet region to visible range, as confirmed by UV-Vis spectrum. Optimized anode electrodes led to solar cells producing high current densities. Pt, CuS, PbS, and Cu2S have been used as electrocatalysts on counter electrodes. The maximum solar conversion efficiency reached in this work was 1.52% and was obtained by using Pt electrocatalyst. CuS, PbS, and Cu2S gave high currents and this was in line with the low charge transfer resistances recorded in their case.

  6. Philoctete’s Healing: Echoes of Dante’s Purgatorio in Walcott’s Omeros

    2017-11-01

    Full Text Available A complex reading adventure is the one awaiting the reader of Omeros, a book-length poem published by Derek Walcott in 1990 and, with a title reminiscent of the Greek poet par excellence, an ideal text to talk about re-writings and re-readings of the Western literary tradition.  As readers, we enter Omeros expecting a re-writing of the Odyssey. We find, instead, a text that recalls, in its structure, themes and prosody, Dante’s Commedia, in particular, the Purgatorio. In our reading of Walcott alongside with Dante, we will concentrate on the character of Philoctete with whom Omeros begins and on the theme of healing that he embodies. While Philoctetes is a minor character in Homer’s Odyssey, Walcott’s appropriation of the Greek character in Omeros is enhanced by his reading of Dante. The theme of healing is pervasive in Walcott’s Omeros, but it is even more emblematic in Dante’s vision of repentance and salvation in the second cantica of his Commedia: the Purgatorio. Interestingly, in Walcott’s “postcolonial Purgatory,” Philoctete remains a minor character and is not turned into a postcolonial hero. Our analysis will focus on the theme of healing, on the vision of history that is unlocked through a comparison between the authors’ worlds, and on Dante’s and Walcott’s creative use of terza rima, the aspect of the poems that – before anything else – brings them together.

    Full Text Available The paper focuses on cosmological ideas of a twentieth-century Russian philosopher Nikolay Lossky (1870-1965. It specifies the place of these ideas within the entire framework of his philosophical views, as well as in the context of his topology of philosophical systems, in particular ― the discrimination between organic and non-organic worldview. A historico-philosophical analysis of Lossky’s cosmology allows revealing the interaction of gnoseological and ontological principles of his system, e.g. explicating the difference of Lossky’s intuitionism from the one of Bergson. The key section of the organic worldview is the doctrine of the hierarchy of substantival agents: the hierarchical personalism, as well as the notions of transcreation, dynamic understanding of matter, and the doctrine of free will closely related to it. The paper specifies the peculiarities of Lossky’s interpretations of panvitalism and panpsychism, as well as the doctrine of reincarnation, which has a particular place in his system. The final stage of Lossky’s cosmological ideas development is his ontological aesthetics: on this stage he understands the world as an embodiment of beauty. The conclusion is drawn that Lossky’s cosmological doctrine is Christian and metaphysical in its nature.

    At present, 72 power reactors are in the condition of being able to operate in U.S., and the total installation capacity has reached 55 million kW, which is equivalent to about 9.5% of the total power generation capacity in U.S. The nuclear power stations produced 12.5% of the total electricity consumption in 1978. Especially in the north eastern part of the U.S., the nuclear power generation occupied 42% of the total power generation at the time of recent peak load, and 47 million barrels of crude oil and 517 million dollars of foreign currency were able to be saved. Moreover, 96 plants amounting to 105 million kW are under construction, and 30 plants of 35 million kW were ordered. Electric power companies, nuclear reactor makers, nuclear fuel and other related industries believe the merits of nuclear power generation and expect that it will flourish if a certain problem is solved. Especially serious problem to which the U.S. nuclear industry is facing now is the problem of uncertainty. Many orders of nuclear power plants have been canceled, and the constructions have been postponed. The capability of the U.S. nuclear industry to construct more than the required facilities, and its extent and the necessary conditions have been investigated by the Atomic Industrial Forum. The important national and international problems of atomic energy are discussed. (Kako, I.)

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available This study investigates the relationships between the geometry of space, theory of perception and theory of narrative in the context of Preston Scott Cohen’s Lightfall – the atrium space of the Tel Aviv Museum of Art in Israel. The starting premise of the study is that it is possible to see the atrium space of the Tel Aviv Museum of Art as an inversion of the atrium space of Frank Lloyd Wright’s Guggenheim Museum in New York. Hence, the main hypothesis is that Cohen’s Lightfall transgresses the language of modernist architecture, moving from the constitution of exhibition space for pure gaze to the constitution of exhibition space for disparate vision. This means breaking with the homogeneous, universal space and time concepts of totalitarianism with the aim of building space-time concepts based on a disjunctive synthesis of narratives, ideologies and discourses of different societies, cultures and arts, or building space-time concepts in a continuous process of becoming. How does the architecture of Cohen’s Lightfall reject the totalitarian modernist interior of the museum as an institution designed solely for the observation of the work of art? How is the theory and practice of contemporary art and culture reflected in the aesthetics of Lightfall and, vice versa, how do the aesthetics of Lightfall influence the practice of contemporary art, culture and society? In other words, in what way does Cohen’s atrium space set the work of art not as autonomous, isolated, neutral and without context but as a unit of discourse? How does Cohen make the transition from the constitution of artistic space for pure gaze to the constitution of artistic space for disparate vision? This study draws on the theoretical investigations of Gilles Deleuze, Félix Guattari, Jacques Derrida, Gilbert Simondon and Pierre Bourdieu.   Article received: December 23, 2016; Article accepted: January 20, 2017; Published online: April 20, 2017 Original scholarly

    The helium/helium heat exchanger (i.e., intermediate heat exchanger: IHX) of a high-temperature gas-cooled reactor (HTGR) system with nuclear heat applications is installed between a primary system and a secondary system. IHX is operated at the highest temperature of 950degC and has a high capacity of up to 600 MWt. A plate-fin-type heat exchanger is the most suitable for IHX to improve construction cost. The purpose of this study is to develop an ultrafine plate-fin-type heat exchanger with a finer pitch fin than a conventional technology. In the first step, fabrication conditions of the ultrafine plate fin were optimized by press tests. In the second step, a brazing material was selected from several candidates through brazing tests of rods, and brazing conditions were optimized for plate-fin structures. In the third step, tensile strength, creep rupture, fatigue, and creep-fatigue tests were performed as typical strength tests for plate-fin structures. The obtained data were compared with those of the base metal and plate-fin element fabricated from SUS316. Finally, the accuracy of the creep-fatigue life prediction using both the linear cumulative damage rule and the equivalent homogeneous solid method was confirmed through the evaluation of creep-fatigue test results of plate-fin structures.

    Full Text Available Local self-governments are reliable business partners. Such belief, confirmed by long-term experience, results in eager collaboration between financial institutions and these entities. Contrary to its name, local self-governments do not constitute the main beneficiaries of the self-government’s factoring. The enterprises which perform investments commissioned by a local commune, district or province are the principal recipients. Such firms may utilise it independently if they have signed contracts with the proper authority and conduct sale with deferred payment, or they may be forced to utilise factoring when they submit their bids in self-government’s tenders within which a refinance guarantee is required. The main aim of the article is to present the mechanism and features of the self-government’s factoring, as well as the benefits which the entities involved enjoy.

  1. Desmond and Moore’s Darwin’s Sacred Cause

    Directory of Open Access Journals (Sweden)

    Allen Esterson

    2013-04-01

    Full Text Available In their book Darwin’s Sacred Cause (2009 Adrian Desmond and James Moore purport to demonstrate that they have provided an original explanation for the inspiration behind Darwin’s determined pursuit of an explanatory theory for the transformation of species of which he became convinced as a result of his experiences during the Beagle voyage of 1831 to 1836. This, they argue, was the “moral passion” that was evoked by his encountering the horrors of slavery during the periods he was able to disembark to explore areas of South America in the years 1832 to 1835. In short, they provide what they describe as “the untold story of how Darwin’s abhorrence of slavery led to our modern understanding of evolution.” This article explores the means by which the authors seek to persuade readers of the validity of their thesis, and concludes that far from providing compelling evidence, by providing a mass of historically interesting material relating to slavery that is actually tangential to their case, they obscure the fact that they fail to accomplish their aim. There is nothing in their account of events that provides a reason for preferring their explanation for Darwin’s devotion to understanding the processes involved in the transformation of species to the known historical facts of Darwin’s early zeal for natural science, exhibited in his childhood exploits with beetles and his more organized scientific activities when he was a student at Cambridge, enabled to come to fruition by his scientific activities during the voyage of the Beagle.

  2. Extracting $\\gamma$ from $B_{s(d)} \\to J/\\psi K_{S}$ and $B_{d(s)} \\to D^{+}_{d(s)} D^{-}_{d(s)}$

    1999-01-01

    A completely general parametrization of the time-dependent decay rates of the modes $B_s\\to J/\\psi K_S$ and $B_d\\to J/\\psi K_S$ is given, which are related to each other through the $U$-spin flavour symmetry of strong interactions. Owing to the interference of current--current and penguin processes, the $B_s\\to J/\\psi K_S$ observables probe the angle $\\gamma$ of the unitarity triangle. Using the $U$-spin symmetry, the overall normalization of the $B_s\\to J/\\psi K_S$ rate can be fixed with the help of the CP-averaged $B_d\\to J/\\psi K_{\\rm S}$ rate, providing a new strategy to determine $\\gamma$. This extraction of $\\gamma$ is not affected by any final-state-interaction effects, and its theoretical accuracy is only limited by $U$-spin-breaking corrections. As a by-product, this strategy allows us to take into account also the penguin effects in the determination of $\\beta$ from $B_d\\to J/\\psi K_S$, which are presumably very small, and to predict the direct CP asymmetry arising in this mode. An analogous strateg...

    Four-dimensional N=2 superconformal field theories have families of protected correlation functions that possess the structure of two-dimensional chiral algebras. In this paper, we explore the chiral algebras that arise in this manner in the context of theories of class S. The class S duality web implies nontrivial associativity properties for the corresponding chiral algebras, the structure of which is best summarized in the language of generalized topological quantum field theory. We make a number of conjectures regarding the chiral algebras associated to various strongly coupled fixed points.

    Gamma-irradiation of S.typhimurium cells up to a dose of 500 krad significantly reduced their toxicity. However, the antigenicity of these cells was not altered, which suggests that these cells could be used as vaccine. The protection offered by the irradiated cells was comparable to that of formalin-treated cells. The radio-vaccine, however, offered an additional advantage of significant detoxification of the endotoxin, thereby minimizing side effects. The lipopolysaccharide extracted from the irradiated S.typhimurium cells offered cross-protection against other Salmonella species tested.

    Full Text Available The article is dedicated to the life path of controversial figure: physician by education, publicist, public and political figure, censor with extreme anti­Ukrainian views S. Shchogolev. In Ukrainian historiography personality of S. Shchogolev has not been the subject of a separate scientific research, while theoretical works of this state and public figure is the subject of much scientific debate and political manipulations. Basing on existing literature the article reveals some touches of historical portrait, journalistic achievements of state and public figure. Being a member of publishing committee he was responsible for censorship of Ukrainian books. Shchogolev owned numerous journalistic heritages, but the pinnacle of his intellectual legacy is the work «Ukrainian movement as modern stage of South­Ukrainian separatism» that was published in 1912. In his major work the author, standing on the Russian nationalistic positions, declared Ukrainian movement to cultural, economical and political separatism. The work is a detailed informative message about institutions, publications and individuals who somehow contributed to the Ukrainian cultural and political life in Russia and abroad. S. Shchogolev’s book in its essence was a fraud facts and distortion of scientific theories. The article presents the analytical thinking of famous politicians and historians about this figure.

  18. Kant’s Machiavellian Moment

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available At least two recent collections of essays – Postmodernism and the Enlightenment (2001 and What’s Left of Enlightenment?: A Postmodern Question (2001 – have responded to postmodern critiques of Enlightenment by arguing that Enlightenment philosophes themselves embraced a number of post-modern themes. This essay situates Kant’s essay Was ist Aufklärung (1784 in the context of this recent literature about the appropriate characterization of modernity and the Enlightenment. Adopting an internalist reading of Kant’s Aufklärung essay, this paper observes that Kant is surprisingly ambivalent about who might be Enlightened and unspecific about when Enlightenment might be achieved. The paper argues that this is because Kant is concerned less with elucidating his concept of Enlightenment and more with characterizing a political condition that might provide the conditions for the possibility of Enlightenment. This paper calls this political condition modernity and it is achieved when civil order can be maintained alongside fractious and possibly insoluble public disagreement about matters of conscience, including the nature and possibility of Enlightenment. Thus, the audience for the Aufklärung essay is not the tax collector, soldier or clergyman, but rather the sovereign. Kant enjoins and advises the prince that discord and debate about matters of conscience need not entail any political unrest or upheaval. It is in this restricted (Pocockian sense that the Enlightenment essay is Kant’s Machiavellian moment.

  17. Study of extragalactic sources with H.E.S.S

    International Nuclear Information System (INIS)

    Giebels, Berrie

    2007-01-01

    The field of Very High Energy (VHE) γ-ray emitting extragalactic sources has considerably evolved since the new generation of atmospheric Cerenkov telescopes (ACT) of improved sensitivity, such as H.E.S.S. array and the MAGIC ACT, have started operating. This has led to a wealth of new clues about emission mechanisms at high energy through the discovery of new sources, more accurate spectra and temporal studies of sources known previously, and simultaneous multi-wavelength (MWL) campaigns since broad band variability is a key phenomenon to the underlying physical mechanisms at play. The fact that some of these new sources are located at redshifts close to z ∼ 0.2 makes them powerful probes of the Extragalactic Background Light (EBL) through the attenuation of γ-rays above 100 GeV

    Full Text Available Learning Management System (LMS supports e-learning as a distant learning. Moodle is one of open source LMS applications that allow embedding multimedia into learning activity in a course, such as video conference session. The paper investigates quality of service (QoS of video conference session embedded in Moodle, i.e. end-to-end delay, jitter, throughput, packet loss and PSNR. Three scenarios were implemented in the experiment. The scenarios were applied on both wire and wireless transmission, and p2p and p2m connections. The investigation results show that the QoS of video conference session meets the standards issued by ITU-T G.1010 and G.114, for minimum bandwidth of 128 kbps. Thus the application of video conferencing that is integrated in Moodle can run well with minimum bandwidth of 128 Kbps.

  20. Properties of superconducting S-I-N, S-I-S, and S-C-S structures with amorphous weak coupling

    International Nuclear Information System (INIS)

    Kozub, V.I.

    1984-01-01

    The properties due to the presence of two-level structure systems in superconducting tunnel junctions with amorphous insulators, as well as in point and bridge Josephson junctions with amorphous surrounds, are investigated. Equations are obtained for tunneling with participation of the two-level systems for the cases of quasistatic tunneling in an S-I-N junction (N is the normal metal) and for the case of Josephson tunneling in an S-I-S junction. It is shown that inelastic tunneling makes an additional contribution to the nonlinearity of the current-voltage characteristic of an S-I-N junction. The specific phenomena of nonexponential relaxation in this junction (in particular, tunnel-current relaxation), which have a 1/t dependence, are discussed. Low-frequency noise in S-I-S and S-C-S structures, due to transitions in the two-level system and having a 1/f dependence at not too small junction sizes are considered. In the case of the stationary Josephson effect this noise has features of critical-current fluctuations that can manifest themselves, in particular as fluctuations of the magnetic flux linked with a weakly coupled superconducting ring. Under conditions of the nonstationary Josephson effect the two-level structures lead to broadening of the Josephson-generation line. It is proposed to use the nonstationary Josephson effect to observe the echo effect in glasses

    The huge western Siberian basin, which Moscow had counted on to ensure rising Soviet petroleum production into the next century, is in steady leading the sharp decline in the former U.S.S.R.'s total oil flow. New data indicate that western Siberia's 1991 crude and condensate production fell to less than 6.5 million b/d. That's down from nearly 7.5 million b/d in 1990 and a peak of 8.28 million b/d in 1988. This paper reports that such low production would make it difficult for Russia to meet the oil needs of other members of the new Commonwealth of Independent States, let alone earn substantial amounts of desperately needed hard currency from crude and refined products sales to foreign countries

    The U.S. nuclear power industry has shown again that it is technically reliable, financially sound, environmentally friendly, secure, and safe. High capacity factors, optimizing refueling and maintenance outages and a commitment to performance in all areas of plant operation and maintenance have contributed to an average availability of 91.8% in 2007. Multiple U.S. Plants achieved a rating of 100% availability. The outstanding performance of the fleet communicates a positive message and illustrates the importance of nuclear energy. The financial community has recognized the performance and is consistent in ranking nuclear as a viable investment opportunity. The environmental benefits of nuclear energy continue to be recognized by former critics and independents. Nuclear is one of the few options for no carbon (a critical greenhouse gas emission) electricity production and environmental groups are now working to preserve the nuclear option. When considering that carbon emissions would be almost one-third higher without nuclear power, the potential for reduction in greenhouse gas emissions is seen as significant. The positive message is not without drawbacks as critics in the current election year are mobilized and vocal. The U.S. industry is standing on the clear record of achievement for reliability and safety. Action is still needed by the U.S. Government to meet obligations to move used nuclear fuel from operating and decommissioned radiation sites to a permanent storage facility. Despite some positive aspects there remain significant challenges to be resolved before the Yucca Mountain repository becoming fully operational is a reality. The US Department of Energy is expected to submit an application to the NRC for licensing of the Yucca site in 2008. Interim storage remains the approach of choice to manage the issue but the industry is looking at an integrated strategy that includes recycling used fuel. Significant research and development is needed in

    The J=1, K=1 and J=2, K=2 transitions of interstellar ammonia have been observed in the molecular clouds near S68, S140, OMC2 and S106. Maps of the ammonia emission obtained with a 2.2-arcmin beam are presented and compared with observations of other interstellar molecules, in particular carbon monoxide and formaldehyde. The distribution of the ammonia emission in OMC2 and S140 resembles more closely that of 2-mm formaldehyde than 13 CO, which is generally more extended. On the other hand, the densities of hydrogen molecules derived from the ammonia observations on the basis of a simple uniform-density model for the source are much lower than those obtained from 2-mm formaldehyde observations. This discrepancy may be resolved either by assuming a 'core-halo' or a 'clumped' structure for the source. The limits to 'halo' emission are used to suggest that the latter possibility is more probable, in which case the medium is well modelled as many clumps of density approximately 10 6 cm -3 and size -2 pc, immersed in a more tenuous medium of density approximately 10sup(3 to 4)cm -3 .

    Full Text Available This article studies Alberdi’s book Del Gobierno De Sud-América Según Las Miras De Su Revolución Fundamental, which was written between 1863 and 1867 – when a monarchy was imposed in Mexico and it was assumed that many South American countries would follow the same path – and published posthumously in 1896. In this controversial text, the author discussed the convenience and adaptation of monarchy to the necessary conditions for progress in Latin America and showed, in the book’s most provocative reflection, an ambiguous preference for constitutional monarchy over republican government. In the end, Alberdi comes out in favor of a centralist republic with a civilizing mission and a secure grip on power.

    Teachers play an important role in society, whose career is considered to be the most glorious one under the sun. They have deep and lifelong influence on students and the prosperity of a country and even the bright future of the whole world. Teacher should be a person with great virtue that sets good examples for the students. However, nowadays, there exist various problems about teacher’s ethics due to complex social, economical, cultural or personal issues. It’s urgent and imperative for teachers to learn and improve professional ethics to be a better mentor. This paper begins with the definition of ethics, emphasizes the importance of teachers’professional ethics, talks about current situation in this area, analyzes the reasons why there are im-moral problems about teachers and suggests some practical strategies on how to improve it.

    In his study of periodic orbits of the three-body problem, Hill obtained a formula connecting the characteristic polynomial of the monodromy matrix of a periodic orbit with the infinite determinant of the Hessian of the action functional. A mathematically rigorous definition of the Hill determinant and a proof of Hill's formula were obtained later by Poincare. Here two multidimensional generalizations of Hill's formula are given: for discrete Lagrangian systems (symplectic twist maps) and for continuous Lagrangian systems. Additional aspects appearing in the presence of symmetries or reversibility are discussed. Also studied is the change of the Morse index of a periodic trajectory upon reduction of order in a system with symmetries. Applications are given to the problem of stability of periodic orbits.

    Keller’s theorem relates the components of the macroscopic dielectric response of a binary two-dimensional composite system with those of the reciprocal system obtained by interchanging its components. We present a derivation of the theorem that, unlike previous ones, does not employ the common assumption that the response function relates an irrotational to a solenoidal field and that is valid for dispersive and dissipative anisotropic systems. We show that the usual statement of Keller’s theorem in terms of the conductivity is strictly valid only at zero frequency and we obtain a new generalization for finite frequencies. We develop applications of the theorem to the study of the optical properties of systems such as superlattices, 2D isotropic and anisotropic metamaterials and random media, to test the accuracy of theories and computational schemes, and to increase the accuracy of approximate calculations.

    Our understanding of QCD under extreme conditions has advanced tremendously in the last 20 years with the discovery of the Quark Gluon Plasma and its characterisation in heavy ion collisions at RHIC and LHC. The sPHENIX detector planned at RHIC is designed to further study the microscopic nature of the QGP through precision measurements of jet, upsilon and open heavy flavor probes over a broad pT range. The multi-year sPHENIX physics program will commence in early 2023, using state-of-the art detector technologies to fully exploit the highest RHIC luminosities. The experiment incorporates the 1.4 T former BaBar solenoid magnet, and will feature high precision tracking and vertexing capabilities, provided by a compact TPC, Si-strip intermediate tracker and MAPS vertex detector. This is complemented by highly granular electromagnetic and hadronic calorimetry with full azimuthal coverage. In this document I describe the sPHENIX detector design and physics program, with particular emphasis on the comprehensive open heavy flavour program enabled by the experiment's large coverage, high rate capability and precision vertexing.

    The hundredth anniversary of the worst ever civilian maritime disaster was also the fiftieth anniversary of the death of arguably its most controversial character, Captain Stanley Lord, skipper of the Californian, a “tramp” steamer that became entrapped in ice just off the Grand Banks of Newfoundland on April 14, 1912. Although Lord was faulted in two widely publicized inquiries for failing to respond to Titanic’s distress signals, there may have actually been a medical reason for his behavior because he suffered from chronic renal disease and most likely had some secondary cognitive impairment due to this disease. An assessment of Lord’s health history shows that he fractured his leg as a young man; suffered from poor eyesight, which led to his premature retirement from the sea by the age of 50; and eventually died from renal failure. Furthermore, his death certificate alludes to previous uremic episodes, perhaps encompassing the time period of the Titanic accident. Lord may have been under some pressure not to reveal his infirmity because doing so could have further jeopardized his career. The literature abounds with evidence that renal insufficiency negatively affects cognition, often years before progression to end-stage renal disease. Captain Lord’s failure to act in a crisis situation may serve as a case in point. PMID:26328096

    The paper gives a geometric proof of the theorem which states that in case of the plane section of a second-order surface of rotation (quadrics of rotation, QR), such conics as an ellipse, a hyperbola or a parabola (types of conic sections) are formed. The theorem supplements the well-known Dandelin’s theorem which gives the geometric proof only for a circular cone and applies the proof to all QR, namely an ellipsoid, a hyperboloid, a paraboloid and a cylinder. That’s why the considered theorem is known as the generalized Dandelin’s theorem (GDT). The GDT proof is based on a relatively unknown generalized directrix definition (GDD) of conics. The work outlines the GDD proof for all types of conics as their necessary and sufficient condition. Based on the GDD, the author proves the GDT for all QR in case of a random position of the cutting plane. The graphical stereometric structures necessary for the proof are given. The implementation of the structures by 3d computer methods is considered. The article shows the examples of the builds made in the AutoCAD package. The theorem is intended for the training course of theoretical training of elite student groups of architectural and construction specialties.

    Full Text Available In this paper, we review and critically evaluate George D. Birkhoff’s work concerning formalisation of aesthetics, as it appeared in his book Aaesthetic Measure from 1933, and discuss its influence on further research in the field. In the book, Birkhoff defines an aesthetic measure M of an art object as the ratio between its order and complexity, or more generally a function f of this ratio: M = f (OC , where O stands for order and C for complexity. The specific definitions of O and C depend on the type of the analysed object. Birkhoff applied the formula to multiple classes of objects (e.g. vases, music, or English poetry and calculated the aesthetic measure for many art objects from these classes. We give an example of Birkhoff’s analysis using polygons, and we further discuss to what extent the ordering of the polygons (or other objects according to the resulting measures can be used, or interpreted, as an ordering according to a degree of aesthetic preference. We also include an extensive bibliography, supplemented by a critical discussion of the influence of Birkhoff’s work on further research.

    2017-10-01

    Full Text Available The article highlights the impact of Freud’s ideas on the Ukrainian prose between the Two World Wars. The analysis of the works by V. Pidmohylnyi and I. Cherniava shows that in literary texts, the erotic-death paradigm is one of the ‘modernist’ algorithms for plot development; in the novellas, this paradigm affects the process of conflict modeling and conflict development. It is rightly believed that V. Pidmohylnyi’s dominant literary interest was the ‘helplessness of human morality before the temptations of crime’. In the novella analyzed in this study, Pidmohylnyi adopts the perspective of the ontogenesis of the human soul at the age of puberty. I. Cherniava explores the theme of subconscious ‘temptation of crime’ a wicked and thoughtless children’s game is sure to unleash. The two stories have many features in common: they are thematically close; in both of them, the plot is based on the Freudian ideas; stylistically, they are realist-oriented works with certain elements of naturalism. The novellas belong to the same type of structurally modified literary works, in which the action is no more important than the resultant psychic changes in the characters. In both novellas, the plot is built around stable structural-behavioural patterns of human culture (in Vania, it is the initiation trial pattern; in The Execution, the perverse play pattern, the game of a trial transformed into a crime. Both works have rather specific expositions, which fulfill the function of ‘Vorgeschichte’ – they tell a reader about certain psychic inclinations of the characters and present the projection of the central theme. In both novellas, the plot type, which determines the development of action, is outlined in the prehistory. Structurally, the two novellas are based on parallelism of events. As to their style, both works bear the features of naturalism.

Rather than trying to decide on whether to reengineer or process improve, they should be focused on their most valuable resource: people. This paper discusses the elements of leadership and how it applies to all individuals in an organization. To get outstanding results from people, they need to begin by making leadership everybody`s business.

    We present the results of the most comprehensive survey of the Galactic plane in very high-energy (VHE) γ-rays, including a public release of Galactic sky maps, a catalog of VHE sources, and the discovery of 16 new sources of VHE γ-rays. The High Energy Spectroscopic System (H.E.S.S.) Galactic plane survey (HGPS) was a decade-long observation program carried out by the H.E.S.S. I array of Cherenkov telescopes in Namibia from 2004 to 2013. The observations amount to nearly 2700 h of quality-selected data, covering the Galactic plane at longitudes from ℓ = 250° to 65° and latitudes |b|≤ 3°. In addition to the unprecedented spatial coverage, the HGPS also features a relatively high angular resolution (0.08° ≈ 5 arcmin mean point spread function 68% containment radius), sensitivity (≲1.5% Crab flux for point-like sources), and energy range (0.2-100 TeV). We constructed a catalog of VHE γ-ray sources from the HGPS data set with a systematic procedure for both source detection and characterization of morphology and spectrum. We present this likelihood-based method in detail, including the introduction of a model component to account for unresolved, large-scale emission along the Galactic plane. In total, the resulting HGPS catalog contains 78 VHE sources, of which 14 are not reanalyzed here, for example, due to their complex morphology, namely shell-like sources and the Galactic center region. Where possible, we provide a firm identification of the VHE source or plausible associations with sources in other astronomical catalogs. We also studied the characteristics of the VHE sources with source parameter distributions. 16 new sources were previously unknown or unpublished, and we individually discuss their identifications or possible associations. We firmly identified 31 sources as pulsar wind nebulae (PWNe), supernova remnants (SNRs), composite SNRs, or gamma-ray binaries. Among the 47 sources not yet identified, most of them (36) have possible

In a hermeneutic-feminist analysis of selected figures and motifs, the article presents new meanings of concepts that are crucial for the understanding of anthropology of corporeality in Nałkowska’s writing project. Among the focal points of the discussion there are the dignity of “lay bodies,” as well as “male” and “female” fantasies of violence.

    Full Text Available One of the most important questions of the religious-philosophical anthropological concept of S.L. Franck are questions about the close relationship between man and God, about sin and suffering, and about the definition of the boundaries of his freedom. In the definition of freedom and its main points, it proceeds not only from Western philosophical thought, but also from the anthropological views and ideas of F. M. Dostoevsky. According to Frank, as in Dostoevsky, the disclosure of the fullness of freedom in man is interconnected with the doctrine of human freedom as self-determination in good and in God, accepting sufering as an indispensable component in his salvation. The article is devoted to the comparison of the basic anthropological and personality concepts, as well as the idea of freedom and its characteristics in the works and works of both thinkers, in order to trace the continuity of Dostoevsky’s tradition with Frank in the framework of his anthropology and personalism in order to prove that for him human freedom and self-Man is an absolute value, his anthropology can be viewed in the context of his philosophy of unity and not contradict it.

    Full Text Available Raynaud’s phenomenon (RP is a common condition that predominantly occurs among women. The onset age in most cases is under 30 years. The phenomenon was first described by M. Raynaud over 150 years ago. Primary (Raynaud’s disease and secondary RP were subsequently distinguished. Pathophysiology of RP has not been fully elucidated yet; RP seems to be a multifactor disease. A pronounced vasospasm in response to stimuli is believed to be caused by disruption in the central and local mechanisms of regulation of vascular tonus. Vascular endothe- lial, intravascular, and neuronal disorders are the key ones among these factors. Structural changes in vessels that can be observed by nailfold capillaroscopy play a significant role in pathophysiology of secondary RP. The key step in the diagnosis of RP is identifying its clinical variant, since secondary RP may be a sign or a premonitory symptom of certain autoimmune, hematologic, endocrine, neoplastic, and other disorders. Secondary RP is most frequently observed in patients with systemic rheumatoid diseases. Therapy of secondary RP provides no satisfactory out- comes, since there is no complete conception about the pathophysiological mechanisms of its development. Different groups of drugs are cur- rently used to treat RP, including calcium channels blockers, phosphodiesterase type 5 inhibitors, endothelin receptor antagonists, etc. This review focuses on pathogenesis, the algorithm of early and differential diagnosis of RP, and current approaches to therapy based on the analysis of the published and our own data.

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available This article addresses the role of house music as a nomadic archival institution, constituted by the musical history of disco, invigorating this dance genre by embracing new production technologies and keeping disco alive through a rhizomic assemblage of its affective memory in the third record of the DJ mix. This exploration will be illustrated through a close analysis of a specific DJ set by a Chicago house music producer, Larry Heard, in the setting of Rotterdam, 2007, in which American house music is recontextualised. Refining the analysis through close attention to one of the tracks played during that particular set, Grand High Priest’s 2006 “Mary Mary”, the analysis shows how DJ and music production practices intertwine to produce a plurality of unstable cultural and musical connections that are temporarily anchored within specific DJ sets. The conceptual framework draws on the work of Deleuze, Guattari and Foucault, as well as Baudrillard’s sense of seduction, with the aim to introduce a fluid notion of mediated nomadic cultural memory, a type of counter-memory, enabled by the third record and thereby to playfully re-imagine the dynamic function of a music archive.

    2017-10-01

    Full Text Available Religion, as well as any individuals’ volitionally chosen ‟worldview,” generally get conceived solely in affirmative terms of value. ‟Religion” has been conceptualized almost solely on the terms of axiology: as the experience of ‟the greatest” holiness (Otto, the purely valuable sacred (Eliade; the most ‟ultimate concern” (Tillich; the symbols accepted to order life (Geertz, or the binding of oneself to deep value (Müller. Yet there are limitations of such axiomatic thinking, limitations that can be exemplified through an interpretation of Derrida’s ‟globolatinization,” which he described as a system of thought that promotes a universalism of pseudo or petit-valuations, and punishes those resistant and inflexible to them in the name of toleration. This essay investigates what happens when this ‟axiomatic” register (i.e. a reduction to a set of values gets displaced in order to conceptualize religion also in terms of the nonvaluable or ‟rejected.” Rejection entails the paradox that what is rejected often speaks to a deeper reality of what in fact is desired. Thus, what we reject usually says infinitely more about us than what we claim to value and affirm. This essay interprets Derrida’s essay ‟How to Avoid Speaking: Denials” alongside his ‟Faith and Knowledge” in order to offer a Derridean conception of religion on the terms of a rejection that amounts to a double-affirmation or de-negation.

    Venezuela had the highest number of human malaria cases in Latin American before 1936. During 1891–1920,malaria was endemic to >600,000 km2 of this country; malaria death rates led to major population decreases during 1891–1920. No pathogen, including the influenza virus that caused the 1918 pandemic, caused more deaths than malaria during 1905–1945. Early reports of malaria eradication in Venezuela helped spark the world's interest in global eradication. We describe early approaches to malaria epidemiology in Venezuela and how this country developed an efficient control program and an approach to eradication.Arnoldo Gabaldón was a key policy maker during this development process. He directed malaria control in Venezuela from the late 1930s to the end of the 1970s and contributed to malaria program planning of the World Health Organization.We discuss how his efforts helped reduce the incidence of malaria in Venezuela and how his approach diverged from World Health Organization guidelines.

    In recent years, a growing interest in the equilibrium of compact astrophysical objects like white dwarf and neutron stars has been manifested. In particular, various modifications due to Planck-scale energy effects have been considered. In this paper we analyze the modification induced by gravity's rainbow on the equilibrium configurations described by the Tolman-Oppenheimer-Volkoff (TOV) equation. Our purpose is to explore the possibility that the rainbow Planck-scale deformation of space-time could support the existence of different compact stars. (orig.)

    1989-01-01

    The author starts his memoir of the 1950s with the story of the discovery of pion and muon decay which was surprising as it represented the spontaneous decay of neutral and charged unstable particles of a new kind. In order to understand the slow decay of other new particles, heavier than nucleons, the author strove to find new selection rules which would apply only to strong and electromagnetic processes, and concluded that looking at ''families'' of elementary particles was a more productive road of inquiry than studying individual particles. He worked on the addition of a new quantum number to include in the selection rules. Later in 1954 two eminent theoreticians, Yang and Mills, published their work on gauge theory which developed field equations to solve the problem of meson and hyperon decay. (UK)

  8. Computer Security: today’s paranoia, tomorrow’s reality

    When the Internet opened its gates to academia in the late 80s and, together with the World Wide Web a few years later, to the general public, computer security was considered somehow irrelevant. People pointing to vulnerabilities and security risks (“hackers”) were labelled as paranoid. But they woke to reality during the outbreak of the “ILOVEYOU” virus in 2000, which caused large scale infections of Windows PCs (including many at CERN).    Similarly, warnings about weaknesses and insecure control systems, issued by CERN and others (see our Bulletin article “Hacking control systems, switching lights off!"), were ignored until the “Stuxnet” attack against control systems in Iran proved them right in 2010. Reality beat 'paranoia' again. Last year, the paranoid fear of many security experts that our whole IT infrastructure might have been infiltrated and spied on turned real, if you believe ...

    In 1928, Dirac published an equation 1 that combined quantum mechanics and special relativity. Negative-energy solutions to this equation, rather than being unphysical as initially thought, represented a class of hitherto unobserved and unimagined particles-antimatter. The existence of particles of antimatter was confirmed with the discovery of the positron 2 (or anti-electron) by Anderson in 1932, but it is still unknown why matter, rather than antimatter, survived after the Big Bang. As a result, experimental studies of antimatter 3-7 , including tests of fundamental symmetries such as charge-parity and charge-parity-time, and searches for evidence of primordial antimatter, such as antihelium nuclei, have high priority in contemporary physics research. The fundamental role of the hydrogen atom in the evolution of the Universe and in the historical development of our understanding of quantum physics makes its antimatter counterpart-the antihydrogen atom-of particular interest. Current standard-model physics requires that hydrogen and antihydrogen have the same energy levels and spectral lines. The laser-driven 1S-2S transition was recently observed 8 in antihydrogen. Here we characterize one of the hyperfine components of this transition using magnetically trapped atoms of antihydrogen and compare it to model calculations for hydrogen in our apparatus. We find that the shape of the spectral line agrees very well with that expected for hydrogen and that the resonance frequency agrees with that in hydrogen to about 5 kilohertz out of 2.5 × 10 15 hertz. This is consistent with charge-parity-time invariance at a relative precision of 2 × 10 -12 -two orders of magnitude more precise than the previous determination 8 -corresponding to an absolute energy sensitivity of 2 × 10 -20 GeV.

    Con dicho proyecto se pretendía, entre otros objetivos, revisar los libros de Lengua del segundo ciclo de Primaria (es decir, de cuarto, quinto y sexto curso con el fin de comprobar cómo se presentaban los valores a través de sus textos y sus paratextos. Con tal cometido, se llevó a cabo una consulta acerca de los manuales usados en los colegios de Cuenca, Albacete y Toledo. De tal consulta provino el corpus de la investigación, que se redujo a los libros de Lengua de las editoriales Anaya, Edelvives, Santillana y SM, que resultaron ser los más utilizados en las tres provincias. El artículo toma estos libros como materia de estudio, y supone un resumen de la investigación. Como tal, será simplificador e incompleto, pero esperamos que resulte lo suficientemente esclarecedor y definitorio en sus ideas y conclusiones como para que el lector se haga una idea de la investigación en su conjunto.

    2005-01-01

    In the light of the recent Lin, Lunin, Maldacena (LLM) results, we investigate 1/2-BPS geometries in minimal (and next to minimal) supergravity in D = 6 dimensions. In the case of minimal supergravity, solutions are given by fibrations of a two-torus T 2 specified by two harmonic functions. For a rectangular torus the two functions are related by a non-linear equation with rare solutions: AdS 3 x S 3 , the pp-wave and the multi-center string. 'Bubbling', i.e. superpositions of droplets, is accommodated by allowing the complex structure of the T 2 to vary over the base. The analysis is repeated in the presence of a tensor multiplet and similar conclusions are reached, with generic solutions describing D1D5 (or their dual fundamental string-momentum) systems. In this framework, the profile of the dual fundamental string-momentum system is identified with the boundaries of the droplets in a two-dimensional plane. (author)

    The theoretical investigation of magnetic field effect on energy spectrum and localization of the electron and oscillator strengths of intraband quantum transitions in the nanostructure CdS/HgS/CdS/HgS/CdS is performed. The calculations are made in the framework of effective mass approximation and rectangular potential barriers model using the method of the expansion of quasi-particle wave functions over the complete basis of functions obtained as the exact solutions of the Schrodinger equation for the electron in the nanostructure without the magnetic field. It is shown that the magnetic field violates the spherical symmetry of the system and takes off the degeneration of energy spectrum with respect to the magnetic quantum number. The energy of the electron in the states with m≥0 increases when magnetic field enhances; for the states with m<0 these dependences are non-monotonous (decreasing at first and then increasing). Moreover, the ground state of electron is formed alternately by the states with m=0, −1, −2, …. Magnetic field influences on the distribution of quasi-particle density. It is shown that the electron significantly changes its localization in the nanostructure with two potential wells tunneling through the potential barrier under the effect of magnetic field, changing the oscillator strengths of intraband quantum transitions.

    Thirty five years ago, while in the neutron cross section group led by Robert Howerton at LLNL, the concept of reconstructing a three dimensional spatial distribution from its projections onto two dimensional planes was tackled by some of us using three now well known methods: simple back projection, Fourier projection theorem methods and iterative least squares algebraic reconstruction. The method of iterative least squares reconstruction was implemented on patient data in the early 1970s using photons from radionuclides detected by the Anger Camera. The method useful for computed tomography was modified to include the attenuation of the photons from an unknown source through an unknown attenuation distribution (a problem thought to be intractable until 1974). These methods along with a multitude of other methods developed by my small group of Ronald Huesman, Grant Gullberg, William Greenberg and Stephen Derenzo were prepared as a library with examples in FORTRAN, RECLBL. Those codes were found useful for computed tomography, geophysical problems and plasma confinement research topics in addition to their use in Nuclear Medicine. The codes were used even in the early days of magnetic resonance imaging when back projection of filtered projection data were used before the incorporation of phase encoding methods. In 1970s computed tomography of a single section of the brain required 4 minutes for single photon tomography or positron emission tomography about 30 minutes were required. Even proton and helium ion tomography were accomplished in the 1970s but with more that 2 hours of data acquisition. Thirty years later CT systems deliver 16 sections per second with 1 mm resolution and PET systems acquire 40 sections with about 4 mm resolution in 5 minutes. Computation times have reduced from 18 hours on the CDC 6600s and 7600s for gated, list mode data to less than 5 minutes in the last 30 years. Similar ratios of improvement have benefited ultrasound and magnetic

    1977-01-01

    The experiment S155 was designed by the Orsay (CSNM-CNRS) Collaboration to observe the properties of exotic light nuclei. It was installed in the PS neutrino tunnel. The photo shows a mass spectrometer (in the background) on line with the PS proton beam which arrives (bottom, right) from the fast extraction FE74. Roger Fergeau stands on the left. The alkaline isotopes produced in the carbon-uranium target heated at 2000°C were swiftly extracted, mass separated, and brought to a detector behind the shielding. Sodium 34 (11 protons and 23 neutrons) was observed and its half-life of only 5 ms was measured. The excited levels 2+ of Magnesium 30 and Magnesium 32 (Sodium descendants) were localised, and the magic number 20 was found to vanish. Thus, the discovery made earlier for Sodium 30 and Sodium 32, with the same apparatus, was confirmed. (See also photo 7706511.)

  18. The gravitational S-matrix

    CERN Document Server

    Giddings, Steven B

    2010-01-01

    We investigate the hypothesized existence of an S-matrix for gravity, and some of its expected general properties. We first discuss basic questions regarding existence of such a matrix, including those of infrared divergences and description of asymptotic states. Distinct scattering behavior occurs in the Born, eikonal, and strong gravity regimes, and we describe aspects of both the partial wave and momentum space amplitudes, and their analytic properties, from these regimes. Classically the strong gravity region would be dominated by formation of black holes, and we assume its unitary quantum dynamics is described by corresponding resonances. Masslessness limits some powerful methods and results that apply to massive theories, though a continuation path implying crossing symmetry plausibly still exists. Physical properties of gravity suggest nonpolynomial amplitudes, although crossing and causality constrain (with modest assumptions) this nonpolynomial behavior, particularly requiring a polynomial bound in c...

On examination, 8 to 10 well-defined, pigmented nodules with raised and pearly borders were seen on the face. Multiple pits were present on the palms and soles. Biopsy of both lesions revealed the presence of basal cell epitheliomas. The patient also gave history of removal of a keratocyst of mandible 10 years back. The case was diagnosed as Gorlin′s syndrome. It is atypical due to the low number of basal cell epitheliomas, the occurrence of only a single odontogenic cyst and the absence of other features usually associated with this condition

    Paul Erdös was one of the most influential mathematicians of the twentieth century, whose work in number theory, combinatorics, set theory, analysis, and other branches of mathematics has determined the development of large areas of these fields. In 1999, a conference was organized to survey his work, his contributions to mathematics, and the far-reaching impact of his work on many branches of mathematics. On the 100th anniversary of his birth, this volume undertakes the almost impossible task to describe the ways in which problems raised by him and topics initiated by him (indeed, whole branches of mathematics) continue to flourish. Written by outstanding researchers in these areas, these papers include extensive surveys of classical results as well as of new developments.

  3. OPEC's strategies

    Energy Technology Data Exchange (ETDEWEB)

    Wirl, Franz [Vienna Univ. (Austria). Faculty of Business, Economics and Statistics

    2012-09-15

    This paper investigates rationale explanations of OPEC's strategies. Accounting for market characteristics in particular the sluggishness of demand and supply allows to explain price jumps as rational OPEC strategies from a narrow economic perspective (up and down) as well as from political objectives (at least up) due to the political payoff from standing up against the 'West'. Although the temptation to accrue this political payoff was and remains high, the narrow economic profit motive coupled with an imperfect cooperation among OPEC members explains past price volatility and high prices much better than the usual reference to political events. A more specific prediction is that OPEC will switch back to setting prices since the current quantity strategy encourages oil importing countries to appropriate rents in particular in connection with the need to mitigate global warming.

    This paper discusses the challenges of financing U.S. exploration from the perspective of an independent oil and gas producer. When Burlington Resources was split into a separate company from the Burlington Northern Railroad three years ago, the company owned extensive resources but had little production capability, and had to resolve the problem of raising development capital. According to the author of this paper, three key elements in the company's perception of the business environment drove its strategy: that the role of independent producers would be crucial in new onshore oil and gas development as the majors moved offshore; that energy prices would remain weak; and that financial market sentiment would not favor a move to leverage the company more highly than its starting-point of 19 percent debt-to-total capital ratio

  7. Corneille’s Heroic Comedies

    Mikhail L. Аndreev

    2017-09-01

    Full Text Available The article deals with a special type of drama specified by Corneille himself as heroic comedy. The playwright placed it somewhere in between two major types of drama, comedy and tragedy, and at the same time distinguished it from tragicomedy that was at the peak of fashion at the beginning of Corneille’s literary career. A typical tragicomedy of the first half of the 17 th century derived either from comedy with the added tragic intonations and overtones or tragedy with various comic figures and situations introduced. The article demonstrates that Corneille practiced a more complex way of uniting different genres. From tragedies, he takes a conflict with parental power (euphemistically represented as a state power but deprives it of its usual tragic severity and ambiguity. As a result, generic characteristics acquire a new meaning while heroic comedy, rather than a combination of elements of different genres, becomes a synthetic new genre in its own right.

    Full Text Available The author commences by introducing Eduard Lindeman's life comparing it to Janez Evangelist Krek, a Slovenian adult educator, animator, politician and researcher. She deals with Lindeman 's life, discussing its influence on his views on adult education. She dwells upon some of Lindeman's recurrent topics like the use of the discussion method as the basic method in adult education, the need for any group in adult education to turn into a social group and above all the social dimension of Lindeman's education of adults. At this point she establishes a comparison with the Slovenian adult education movement of the elderly namely The Third Age University. She critically approaches Lindeman's belief that only method and not the content is important in adult education. At several points she compares Lindeman with modern social French thinkers.

    Zahnle, Kevin; Schaefer, Laura; Fegley, Bruce

    2010-01-01

    Earth is the one known example of an inhabited planet and to current knowledge the likeliest site of the one known origin of life. Here we discuss the origin of Earth’s atmosphere and ocean and some of the environmental conditions of the early Earth as they may relate to the origin of life. A key punctuating event in the narrative is the Moon-forming impact, partly because it made Earth for a short time absolutely uninhabitable, and partly because it sets the boundary conditions for Earth’s subsequent evolution. If life began on Earth, as opposed to having migrated here, it would have done so after the Moon-forming impact. What took place before the Moon formed determined the bulk properties of the Earth and probably determined the overall compositions and sizes of its atmospheres and oceans. What took place afterward animated these materials. One interesting consequence of the Moon-forming impact is that the mantle is devolatized, so that the volatiles subsequently fell out in a kind of condensation sequence. This ensures that the volatiles were concentrated toward the surface so that, for example, the oceans were likely salty from the start. We also point out that an atmosphere generated by impact degassing would tend to have a composition reflective of the impacting bodies (rather than the mantle), and these are almost without exception strongly reducing and volatile-rich. A consequence is that, although CO- or methane-rich atmospheres are not necessarily stable as steady states, they are quite likely to have existed as long-lived transients, many times. With CO comes abundant chemical energy in a metastable package, and with methane comes hydrogen cyanide and ammonia as important albeit less abundant gases. PMID:20573713

    The Landsat mosaic of Tunisia funded by USAID for the Remote Sensing Laboratory, Soils Division, Ministry of Agriculture, Tunisia, was completed by the USGS in September 1983. It is a mixed mosaic associating digital corrections and enhancements to manual mosaicking and corresponding to the Tunisian request for high resolution and the limited available funds. The scenes were processed by the Environmental Research Institute of Michigan, resampling the data geodesically corrected to fit the Universal Transverse Mercator projection using control points from topographic maps at 1:50,000 and 1:100,000 scales available in the U. S. The mosaicking was done in the Eastern Mapping Center under the supervision of the Graphic Arts System Section. The three black and white mosaics were made at the 1:1,000,000 scale and various products generated. They included color film positives at 1:2,000,000 and 1:4,000,000 scales reproducible in the Remote Sensing Laboratory in Tunis and corresponding color prints as well as tricolor prints at various scales from 1:500,000 to 1:2,000,000.

    , shuttles between a free state and the 26-S proteasome, bringing substrate to the complex. However, S5a was not found in the free state in HeLa cells. Besides, all subunits in PA700, including S5a, exchanged at similar low rates. It therefore seems that 26-S proteasomes function as stable entities during...

    The international climate agreement does make sense if they are supported by the United States, the world's largest emitters of greenhouse gas (GHG) per capita. But this country is now bound by any treaty that forced him to reduce this pollution. The national energy transition is delayed: the lifestyle and the American system of production are still largely rely on fossil fuels. The coming to power of Barack Obama, who announced his intention to engage in action against climate change, had raised hopes of the international community: the Copenhagen compromise and agreements resulting from Cancun also directly the involvement of American and Chinese leaders. Since then, however, the context has changed dramatically: the economic crisis makes priority policies to boost growth. The abandonment of the climate bills in Congress, the Supreme Court decision restricting States' initiatives and actions taken by the Republican opposition to block the regulations of the Federal Agency for Environmental Protection (EPA) led to a slowing of presidential ambitions. They are focusing on an energy security strategy, providing for the operation of large domestic reserves of oil, reducing import dependency - constant of U.S. policy since the presidency of Richard Nixon - the use of alternatives energy, and finally the acceleration of energy efficiency in transport and construction. This orientation requires a staunch support to innovation, according to the will of American leadership in global technology industry green. Internationally, the meeting between Chinese and U.S. presidents in Copenhagen has identified the concessions acceptable to each of these key players in the negotiations. The special envoy of the White House reminds happy: the United States does not object to a new global agreement but discussions about it should only take the implementation of measures adopted in Cancun, whose variation to be the main issue of the Durban conference in late November 2011.

    A key ingredient to searches for physics beyond the Standard Model in $B^{0}_{s}$ mixing phenomena is the measurement of the $B^{0}_{s}$-$\\bar{B}^{0}_{s}$ oscillation frequency, which is equivalent to the mass difference $\\Delta m_{s}$ of the $B^{0}_{s}$ mass eigenstates. Using the world's largest $B^{0}_{s}$ meson sample accumulated in a dataset, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb experiment at the CERN LHC in 2011, a measurement of $\\Delta m_{s}$ is presented. A total of about 34,000 $B^{0}_{s}\\rightarrow D^{-}_{s}\\pi^{+}$ signal decays are reconstructed, with an average decay time resolution of 44 fs. The oscillation frequency is measured to be $\\Delta m_{s}$ = 17.768 $\\pm$ 0.023 (stat) $\\pm$ 0.006 (syst) ps$^{-1}$}, which is the most precise measurement to date.
