    Full Text Available The main objective of this study was to conduct an analysis of the rheological properties of StelliteTM 21 alloy in the semi-solid state, as the results could be used for identifying the appropriate temperature range for thixoforming of this alloy, and a secondary objective of the experimental work was the development of mathematical model of the alloy’s apparent viscosity. Such viscosity models are necessary for numerical simulations of the thixoforming processes. The StelliteTM 21 alloy exhibits high hardness and thus shaping in the semi-solid state is promising route of production of parts from this alloy. Within the confines of experimental work the measurement methods of the rheological properties at high temperatures was developed. They are based on the use of specially designed viscometer equipped with high temperature furnace.

    The research on a thermal stress control layer (TSCL) begins to undertake to reduce residual stress and strain in the vicinity of the joined region between the hardfacing layer and the base part. The goal of this paper is to estimate the material combination and the thickness of TSCL for the Stellite21 hardfaced STD61 hot working tool steel via three-dimensional finite element analysis (FEA). TSCL is created by the combination of Stellite21 and STD61. The thickness of TSCL ranges from 0.5 mm to 1.5 mm. The influence of the material combination and the thickness of TSCL on temperature, thermal stress and thermal strain distributions of the hardfaced part have been investigated. The results of the investigation have been revealed that a proper material combination of TSCL is Stellite21 of 50 % and STD61 of 50 %, and its appropriate thickness is 1.0 mm

    Co (OH) 2 , the increase in the corrosion potential due to irradiation does not result in an increase in the rate of cobalt dissolution from the Stellite. The oxide film that grows with irradiation present is uniform. SEM and XPS analyses of this oxide film indicate that there is no preferential oxidation or dissolution occurring on either the cobalt-rich phase or the chromium-rich phase of the alloy. (authors)

    Solid state Stellite6 coatings were deposited on steel substrate by friction surfacing and compared with Stellite6 cast rod and coatings deposited by gas tungsten arc and plasma transferred arc welding processes. Friction surfaced coatings exhibited finer and uniformly distributed carbides and were characterized by the absence of solidification structure and compositional homogeneity compared to cast rod, gas tungsten arc and plasma transferred coatings. Friction surfaced coating showed relatively higher hardness. X-ray diffraction of samples showed only face centered cubic Co peaks while cold worked coating showed hexagonally close packed Co also. - Highlights: ► Stellite6 used as coating material for friction surfacing. ► Friction surfaced (FS) coatings compared with casting, GTA and PTA processes. ► Finer and uniformly distributed carbides in friction surfaced coatings. ► Absence of melting results compositional homogeneity in FS Stellite6 coatings.

  5. The Basics of Stellites in Machining Perspective

    Full Text Available Stellites are cobalt (Co-based superalloys available in two main combinations: (a a Tungsten (W group with composition of Co-Cr-W-C, and (b a Molybdenum (Mo group containing Co-Cr-Mo-C. Stellites possess outstanding corrosion resistance, oxidation resistance, wear resistance, heat resistance, and low magnetic permeability. Components made of stellites work well in highly corrosive environments and maintain these advantageous properties at elevated temperatures. Components made of stellites are widely used in the oil and gas, automotive, nuclear power, paper and pulp, chemical and petrochemical, refineries, automobile, aerospace and aircraft industries. By virtue of their nonmagnetic, anticorrosive and non-reactivity to human body-fluid properties, stellites are used in medical surgery and in surgical tools, tooth and bone implants and replacements, heart valves, and in heart pacemakers. The hardness range of stellites is from 32 to 55 HRC, which makes stellites brittle materials but they have a low Young’s modulus. Due to their high hardness, dense but non-homogeneous molecular structure and lower thermal conductivity, machining operations for parts made of stellites are extremely difficult, categorising stellites as difficult-to-machine materials like Ti-alloys, inconels, composites and stainless steels. Usually, machine components made of stellites are produced by a deposition method onto steel substrates instead of expensive solid stellite bars. The rough surfaces of deposited stellites are then finished by grinding, rather than some other economic machining process, which is costly and time-consuming, making stellite products very expensive. This paper provides a basic overview of stellites applicable in engineering, their significances and specific applications, advantages and disadvantages in respect of machining processes.

  8. Failure Mechanism of a Stellite Coating on Heat-Resistant Steel

    2017-09-01

    The Stellite 21 coating on the heat-resistant steel X12CrMoWVNbN10-1-1 (so-called COSTE) used in a steam turbine valve was found to be fatigue broken after service at around 873 K (600 °C) for about 8 years. In order to investigate the failure mechanism, a fresh Stellite 21 coating was also prepared on the same COSTE steel substrate by using the similar deposition parameters for comparison. It was found that the Stellite 21 coating was significantly diluted by the steel, resulting in a thin Fe-rich layer in the coating close to the fusion line. Such high Fe concentration together with the incessant Fe diffusion from the steel substrate to the coating during the service condition (about 873 K (600 °C) for long time) induced the eutectoid decomposition of the fcc α-Co(Fe,Cr,Mo) solid solution, forming an irregular eutectoid microstructure that was composed of the primitive cubic α'-FeCo(Cr,Mo) phase and the tetragonal σ-CrCo(Fe,Mo) phase. The brittle nature of such α'/ σ eutectoid microstructure contributed to the fatigue fracture of the Stellite 21 coating, resulting in an intergranular rupture mode.

    The self-welding behavior of two similar materials, Stellite 6 and Stellite 156, in sodium are discussed. The materials were tested at temperatures from 850 to 1140 0 F for time periods up to six-months while immersed in flowing sodium. Contact stresses ranged from 6000 psi to 16,000 psi on contact areas from 0.35 to 0.47 square inches. All separation tests to determine the extent of self-welding were conducted in a tensile mode. The surface morphologies of the samples before and after each test were measured. At temperatures of 1115 0 F and above, almost all the Stellite 6 specimens indicated a significant tendency toward self-welding within a relatively short period of time (one week). Stellite 156 couples also developed a strong self-weld bond at 1060 0 F after six-month exposure

    Radioactive hotspots found either in the primary heat transport circuit or auxiliary circuits of nuclear reactors are mainly due to particles containing activated cobalt. The main source of these particles are stellite alloys that are rich in cobalt and are used in primary cooling circuits in valves, pumps, etc. Due to either mechanical erosion or erosion coupled with corrosion under flow conditions (known as tribocorrosion), these stellite particles are released into the system. They are then activated by neutron absorption in the reactor core before being deposited on out-of-core surfaces, causing radiation exposure problems. In this paper, the possibility of dissolving stellite particles by using an oxidation-complexation process has been explored. Permanganate based reagents were evaluated for their efficiency in conditioning the stellite particles for their dissolution with organic acids. Permanganic acid was found to be the superior conditioning agent. Two alloys of stellite, viz. stellites no. 3 and no. 6, were studied with respect to their dissolution behavior

  11. Dynamic strain aging in Haynes 282 superalloy

    Full Text Available Haynes 282 is a newly introduced Ni-based superallony, developed to provide a combination of high-temperature mechanical properties, thermal stability and processability. The present contribution investigates the effect of dynamic strain aging (DSA on the deformation behaviour of Haynes 282 during monotonic and cyclic loading. It is shown that DSA (presumably related to carbon diffusion based on rough estimates of the activation energy completely dominates the development of the stress during cycling at intermediate temperatures, leading to extensive cyclic hardening and serrated yielding. However, no clear effects on the fatigue life or the resulting dislocation structure could be observed. The tensile properties were not severely affected, in spite of the presence of extensive serrated yielding, although a reduction in ductility was observed in the DSA temperature regime. During monotonic loading at lower strain rates indications of an additional DSA mechanism due to substitutional elements were observed.

  12. Status of Stellite 6 friction testing

    For the past several years, researchers at the Idaho National Engineering and Environmental Laboratory, under the sponsorship of the US Nuclear Regulatory Commission, Office of Nuclear Regulatory Research, have been investigating the performance of motor-operated valves subjected to design basis flow and pressure loads. Part of this research addresses the friction that occurs at the interface between the valve disc and the valve body seats during operation of a gate valve. In most gate valves, these surfaces are hardfaced with Stellite 6, a cobalt-based alloy. Analytical methods exist for predicting the thrust needed to operate these valves at specific pressure conditions. To produce accurate valve thrust predictions, the analyst must have a reasonably accurate, though conservative, estimate of the coefficient of friction at the disc-to-seat interface. One of the questions that remains to be answered is whether, and to what extent, aging of the disc and seat surfaces effects the disc-to-seat coefficient of friction. Specifically, does the environment in a nuclear plants piping system cause the accumulation of an oxide film on these surfaces that increases the coefficient of friction; and if so, how great is the increase? This paper presents results of specimen tests addressing this issue, with emphasis on the following: (1) the characteristics and thickness of the oxide film that develops on Stellite 6 as it ages; (2) the change in the friction coefficient of Stellite 6 as it ages, including the question of whether the friction coefficient eventually reaches a plateau; and (3) the effect in-service cycling has on the characteristics and thickness of the oxide film and on the friction coefficient

    The Duane Arnold Energy Center was seeking methods to reduce dose rates from the drywell due to Co-60. Duane Arnold is known in the industry to have one of the highest drywell dose rates from the industry standardized 'BRAC' point survey. A prime method to reduce dose rates due to Co-60 is the accelerated replacement of stellite pins and rollers in control rod blades due to their high stellite (cobalt) content. Usually the cobalt content in alloys of stellite is greater than 60% cobalt by weight. During the RFO-12 refueling outage at Duane Arnold, all of the remaining cobalt bearing control rod blades were replaced and new stellite free control rod blades were installed in the core. This left Duane Arnold with the disposal of highly radioactive stellite pins and rollers. The processing of control rod blades for disposal is a very difficult evolution. First, the velocity limiter (a bottom portion of the component) and the highly radioactive upper stellite control rod blade ins and rollers are separated from the control rod blade. Next, the remainder of the control rod blade is processed (chopped and/or crushed) to aid packaging the waste for disposal. The stellite bearings are then often carefully placed in with the rest of the waste in a burial liner to provide shielding for disposal or more often are left as 'orphans' in the spent fuel pool because their high specific activity create shipping and packaging problems. Further investigation by the utility showed that the stellite balls and pins could be recycled to a source manufacturer rather than disposed of in a low-level burial site. The cost savings to the utility was on the order of $200,000 with a gross savings of $400,000 in savings in burial site charges. A second advantage of the recycling of the stellite pins and rollers was a reduction in control in radioactive waste shipments

    Depositing hard materials such as Stellite-6 solely by cold spray (CS) is challengeable due to limited ability of plastic deformation. In this study, the deposition of Stellite-6 powder was achieved by supersonic laser deposition (SLD) which combines CS with synchronous laser irradiation. The surface morphology, deposition efficiency, track shape of Stellite-6 coatings produced over a range of laser irradiation temperatures were examined so as to reveal the effects of varying laser energy inputting on the deposition process of high strength material. The microstructure, phase composition and wear/corrosion resistant properties of the as-deposited Stellite-6 coatings were also investigated. The experimental results demonstrate that the surface flatness and deposition efficiency increase with laser irradiation temperature due to the softening effect induced by laser heating. The as-deposited Stellite-6 tracks show asymmetric shapes which are influenced by the relative configuration of powder stream and laser beam. The SLD coatings can preserve the original microstructure and phase of the feedstock material due to relatively low laser energy inputting, which result in the superior wear/corrosion resistant properties as compared to the counterpart prepared by laser cladding.

    Concerns about overuse and potential contamination of major aquifers in the southeastern part of North Carolina resulted in the initiation of a subsurface water quality study in February 2001. The focus of this study was to examine variations in nutrients (NO3-, TRP, SO42- Cl-, NH4+) and total dissolved Fe in the Cretaceous Peedee and Tertiary Castle Hayne Limestone aquifers of northeastern New Hanover County. Water samples were collected monthly for one year from sixteen wells located in the Porters Neck area (west of the Intracoastal Waterway and south of Futch Creek) and four springs located on the south side of Futch Creek. Variations in selective nutrient concentrations were measured between and within each aquifer. Concentrations of NH4+ and Fe increased in the Peedee sandstone aquifer during the warmer summer and early fall months. In late summer to early fall, Fe, NO 3-, NH4+, and TRP concentrations in the Castle Hayne Limestone aquifer were significantly higher than in the spring and winter months. Chloride and SO 42- concentrations for the Castle Hayne Limestone aquifer both increased during the warmer months, probably as a result of saltwater intrusion. Factors considered for nutrient and Fe variance include: temperature variation, anaerobic conditions, subsurface stratigraphy/structure, recharge locations, site location and surface fertilization. The shallower Castle Hayne Limestone aquifer showed seasonal variability in the study area, whereas the Peedee sandstone aquifer showed little to no seasonal variability. Increases in NO3- and TRP lagged slightly behind periods of high fertilization and were more prevalent down-dip of a major golf course. Nutrient content and seasonal variation of Futch Creek springs indicated that they originate from the Castle Hayne Limestone aquifer.

    Some of the Indian pressurized heavy water reactors (PHWRs) which use Stellite balls in the ball and screw mechanism of the adjustor rod drive mechanism in the moderator circuit have encountered high radiation fields in the moderator system due to 60 Co. Release of particulate Stellite is responsible for the hotspots in addition to the general uniform contamination of internal surfaces with 60 Co. Extensive laboratory studies have shown that it is possible to dissolve these Stellite particles by adopting a three-step redox process with permanganic acid as the oxidizing agent. These investigations with inactive Stellite in powder form helped to optimize the process conditions. Permanganic acid was found to have the highest dissolution efficiency as compared to alkaline and nitric acid permanganate. The susceptibility of Stellite to corrode or dissolve was found to depend on the concentration of the permanganate, pH and temperature of the process and microstructure of the Stellite alloy. This process was evaluated for its effectiveness on components from nuclear power plants. Component decontamination was carried out on adjustor rod drive assemblies which had 60 Co activity due to Stellite particles with the radiation field ranging from 3 R . h -1 to 20 R . h -1 . They were subjected to decontamination with permanganic acid as the oxidizing agent, followed by citric acid and a solution containing ethylenediaminetetraacetic acid, ascorbic acid and citric acid in a 4:3:3 ratio by weight as the reducing formulation. In the first trial, one adjustor rod drive mechanism was subjected to decontamination. After two cycles of treatment, an average decontamination factor (DF) of 6.8, with a maximum DF of 11.7, was achieved. The same process but with one cycle was repeated on eight more adjustor rod drive mechanisms. 60 Co activity in the range of 13-93 mCi was removed from these adjustor rods. Loose contamination of the order of 30 000-40 000 decays per min and cm 2 observed

    The purpose of this study was to produce Co-based Stellite 6 superalloy components by using the method of Powder Injection Molding (PIM) and to characterize the microstructural and mechanical properties of the produced components. The experimental studies were started through the formation of feedstock by mixing Stellite 6 powder with a multicomponent binder system. Prepared feedstock was formed by utilizing powder injection molding technique. Then the molded samples were subjected to the solvent and thermal debinding processes. Different sintering cycles were applied to the raw components for the purpose of determining the optimum sintering conditions. The densities of the sintered components were determined in accordance with the Archimedes' principle. The microstructural characterization was performed through scanning electron microscope (SEM) analysis, energy dispersive spectrometry (EDS) analyses, and X-ray diffraction (XRD) analysis. Hardness measurement and tensile test were conducted in order to determine the mechanical properties. The results illustrated that the injection molded Stellite 6 components were composed of fine and equiaxed grains, plenty of carbide precipitates exhibiting homogenous distribution throughout the microstructure formed at the grain boundaries and thus the mechanical properties were considerably high.

    Laser surface melting (LSM) process has been applied on the plasma transferred arc (PTA) deposited Stellite 12 and 10 wt% Mo alloyed Stellite 12 in this study. Following the LSM process, structural and mechanical property comparison of the LSM'ed surfaces has been made. Hardness of the LSM'ed surfaces was measured as 549 HV and 623 HV for the Stellite 12 and Stellite 12 + 10 wt% Mo deposits, respectively. Despite their different hardness and structural features, the LSM'ed surfaces exhibited similar tribological performance at room temperature (RT), where fatigue wear mechanism operates. However, the wear at 500 °C promotes tribo-oxide layer formation whose composition depended on the alloying with Mo. Thus, addition of 10 wt% Mo into Stellite 12 PTA deposit has remarkably enhanced the high temperature wear performance of the LSM'ed surface as a result of participation of complex oxide (CoMoO4) in tribo-oxide layer.

    Highlights: > This study is useful to optimize the welding process variables in order to control the heat input and cooling rates such that the hardness and dilution of the clad could be estimated. > Central composite rotatable design technique with five-level, four-factor full-factorial design matrix and mathematical models was used to predict hardness and dilution of pulsed gas tungsten arc weld cladding of stellite6 on carbon steel with high accuracy. > The welding current is an effective parameter affecting heat input and melting. In this regard, it is the most important process parameter which influences the dilution. Increase welding current leads to increase in dilution percentage and vice versa. The effect of percentage on time is less important when compared to the other factors. > The results predicted by mathematical models were close to those obtained by experiments. The confirmation tests also indicated high correlation between the mentioned values. > All of the chosen pulse GTAW parameters were significant and showed a noticeable influence on clad dilution. - Abstract: Stellite 6 is a cobalt-base alloy which is resistant to wear and corrosion and retains these properties at high temperatures. The exceptional wear resistance of Stellite 6 is mainly due to the unique inherent characteristics of the hard carbides dispersed in a Co-Cr alloy matrix. In this study, pulsed tungsten inert gas (TIG) cladding process was carried out to deposit Stellite 6 on plain carbon steel plate. The beneficial effects of this cladding process are low heat input, low distortion, controlled weld bead volume, less hot cracking tendency, less absorption of gases by weld pool and better control of the fusion zone. The dilution effect is a key issue in the quality of cladded layers and, in this regard, the pulsed current tungsten inert gas (PCTIG) was performed to decrease excess heat input and melting of substrate. This paper deals with the investigation of the hardness and

    Chemical composition and nutritional evaluation as well as physicochemical and functional properties of seed flour of Acacia tortilis (Forssk.) Hayne ssp. raddiana were studied. The results indicated that seeds contained 5.30% moisture, 3.99% ash, 9.19% fat, 14.31% fiber, 27.21% protein and 45.30% carbohydrates. Potassium was the predominant element followed by calcium and then phosphorous. Phytic acid, tannins and trypsin inhibitor as antinutrients were detected. The amino acid profile compared well with FAO/WHO recommended pattern except for cystine/methionine, isoleucine, tyrosine/phenylalanine, lysine and threonine. Also, the first limiting amino acid was lysine. Fatty acid composition showed that linoleic acid was the major fatty acid, followed by palmitic, stearic, oleic and arachidic acids. The seed oil showed absorbance in the ultraviolet ranges, thus it can be used as a broad spectrum UV protectant. For physicochemical and functional properties, acacia seeds flour had excellent water holding index, swelling index, foaming capacity and foam stability. Copyright © 2016 Elsevier Ltd.

    The life cycle requirements for advanced Ni alloys are very demanding and can be on the order of several hundreds of thousands of hours. Results are presented on a wrought Ni-based superalloy designed within the nominal chemistry range of Haynes 282 with a fixed amount of γ' strengthening phase, and either low Al or Ti (within the alloy specification) to give different ratios of Ti/Al, and thus, different γ' misfit with the γ matrix. The effect that these changes have on the γ' misfit and its relevance to long-term microstructural stability is being explored both experimentally as well as with computational modeling with results through almost 10,000 h. The basics of the modeling approach are presented as are the procedures for evaluating the γ' volume fractions from transmission electron microscopy (TEM) micrographs and correcting these volume fractions for truncation error due to TEM foil thickness. Results on each alloy formulation are compared and discussed with respect to possible γ' coarsening due to the different Ti/Al ratio and what this might mean for the long-term stability of the alloy.

    The results of high-temperature axial and torsional low-cycle fatigue experiments performed on Haynes 188, a wrought cobalt-base superalloy, are reported. Fatigue tests were performed at 760 C in air on thin-walled tubular specimens at various ranges under strain control. Data are also presented for coefficient of thermal expansion, elastic modulus, and shear modulus at various temperatures from room to 1000 C, and monotonic and cyclic stress-strain curves in tension and in shear at 760 C. The data set is used to evaluate several multiaxial fatigue life models (most were originally developed for room temperature multiaxial life prediction) including von Mises equivalent strain range (ASME boiler and pressure vessel code), Manson-Halford, Modified Multiaxiality Factor (proposed here), Modified Smith-Watson-Topper, and Fatemi-Socie-Kurath. At von Mises equivalent strain ranges (the torsional strain range divided by the square root of 3, taking the Poisson's ratio to be 0.5), torsionally strained specimens lasted, on average, factors of 2 to 3 times longer than axially strained specimens. The Modified Multiaxiality Factor approach shows promise as a useful method of estimating torsional fatigue life from axial fatigue data at high temperatures. Several difficulties arose with the specimen geometry and extensometry used in these experiments. Cracking at extensometer probe indentations was a problem at smaller strain ranges. Also, as the largest axial and torsional strain range fatigue tests neared completion, a small amount of specimen buckling was observed.

  19. Micromorphology of the floral nectary of red horse chestnut (Aesculus ×carnea Hayne

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available In Europe Aesculus ×carnea Hayne is planted in cities as an avenue tree. Compared to A. hippocastanum L., it is more drought resistant, but less resistant to low temperatures. A. ×carnea is a lower tree than A. hippocastanum and develops a smaller corolla. It produces dark green, shiny and crinkled leaves. Its flowers have different colours, from bright pink to carmine red. The nectary glands secrete nectar abundantly. Due to the long corolla tube, nectar is difficult to reach for bees. The aim of this study was to investigate the topography and micromorphology of the nectaries of A. ×carnea using scanning electron microscopy. The study shows that the nectary gland of red horse chestnut forms an incomplete ring around the base of the staminal filaments, surrounding only four stamens out of the seven that occur in the flower. Three stamens are outside the nectary. In its widest place, the nectary diameter reaches 2.7 mm. Three expanded portions of the gland can bee seen in the marginal part of the nectary, adjoining the petals. The part of the nectary adjacent to the filaments forms a convex protrusion with a wavy appearance (shape, which results from the vicinity of the filaments. Nectar is secreted through numerous stomata located beneath the convex part of the nectary. The stoma length is 21.7 μm, while the width 23.3 μm. In the material examined, most stomata had open pores. Secretion was observed in many places. The stomata were surrounded by 6-7 guard cells; this allows them to be classified as the cyclocytic type. The cells of the stomatal complex were raised above the surface of the other epidermal cells. The walls of the guard cells and of the adjacent epidermal cells were covered by a cuticle with irregular striation.

    Long-term aging behaviors of a solid solution hardened Ni-base superalloy, Haynes 230 at high temperature have not been fully investigated yet. In this study, long-term aging tests of Haynes 230 was carried out to evaluate microstructure changes especially in carbide evolution. In addition, its consequential effects on tensile property such as tensile strength and elongation were discussed. In Haynes 230, a nucleation of the secondary carbides was dominant at 800 .deg. C ageing while growth at 900 .deg. C ageing. In addition, after aging at 800 .deg. C, transition of primary W-rich M 6 C carbides (break down) were observed and it showed high W content (up to 70 at.% W) compared to un-aged W-rich M 6 C carbides (around 30 at.% W). Coarsened Cr- and Ni-rich phase surrounded by carbide depleted region and high W-rich M 6 C carbide along the grain boundary were formed only at 900 .deg. C after long-term exposure above 10000 h. Tensile strength of aged Haynes 230 increased at 800 .deg. C while decreased at 900 .deg. C due to the formation of secondary carbide within the grains at 800 .deg. C. Decrease in elongation would be resulted from the coarsened and continuous carbides at the grain boundary as well as Cr- and Ni-rich phase along the grain boundary

    Research highlights: > The microstructure of the surface layer consisted of carbides embedded in a Co-rich solid solution with dendritic structure. Primary phases formed during the process were identified as Co(FCC) and lamellar eutectic phases (M{sub 23}C{sub 6}, M{sub 6}C, Cr{sub 7}C{sub 3}). > Microhardness profiles showed that hardness increases from interface to the coating surface. This is due to the finer size of the grains at coating surface in comparison to that at interface and also diffusion of Fe adjacent to the interface. > The delamination was suggested as the dominant mechanism of the wear. In this regard, plate-like wear debris consisted of voids and cracks. In addition, due to increase in surface temperature, Cr{sub 2}O{sub 3} oxide phase was formed during wear tests. - Abstract: This paper deals with the investigation of the microstructure and wear behavior of the stellite 6 cladding on precipitation hardening martensitic stainless steel (17-4PH) using gas tungsten arc welding (GTAW) method. 17-4 PH stainless steel is widely used in oil and gas industries. Optical metallography, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) were employed to study the microstructure and wear mechanisms. X-ray diffraction analysis was also used to identify phases formed in the coating. The results showed that the microstructure of the surface layer consisted of carbides embedded in a Co-rich solid solution with a dendritic structure. In addition, the dendritic growth in the coating was epitaxial. Primary phases formed during the process were Co (fcc), Co (hcp), lamellar eutectic phases, M{sub 23}C{sub 6} and Cr{sub 7}C{sub 3} type carbides. The results of the wear tests indicated that the delamination was the dominant mechanism. So, it is necessary to apply an inter-layer between the substrate and top coat.

    Haynes Alloy 230 was specifically designed to have excellent long-term thermal stability and resistance to the precipitation of damaging phases. This paper describes in detail studies on the effects of long-term high temperature exposure on the hardness, microstructural changes and tensile properties of thermally exposed samples of Haynes Alloy 230. The samples from the 2mm thick sheet material have been investigated using X-Ray diffraction and advanced electron microscopy techniques (FEGSEM, TEM etc.). The evolution of the precipitating phases was monitored across a wide range of temperatures (from 500 C to 1170 C) and durations (from 24 hours up to 30000 hours) and several key phases have been identified. In addition to the primary W-rich carbide and the precipitation of Cr-rich M{sub 23}C{sub 6}, a new brittle phase/carbide was observed within the microstructure at the highest exposure temperatures (above 930 C).

    Full Text Available Ni-based superalloys are extensively used in high-responsibility applications in components of aerospace engines and gas turbines with high temperature service lives. The wrought, γ’-strengthened superalloy Haynes 282 has been recently developed for applications similar to other common superalloys, such as Waspaloy or Inconel 718, with improved creep behavior, thermal stability, and fabrication ability. Despite the potential of Haynes 282, there are still important gaps in the knowledge of the mechanical behavior of this alloy. In fact, it was not possible to find information concerning the mechanical behavior of the alloy under impulsive loading. This paper focuses on the mechanical characterization of the Haynes 282 at strain rates ranging from 0.1 to 2800 s−1 and high temperatures ranging from 293 to 523 K using Hopkinson bar compression tests. The experimental results from the thermo-mechanical characterization allowed for calibration of the Johnson–Cook model widely used in modeling metallic alloy’s responses under dynamic loading. Moreover, the behavior of Haynes 282 was compared to that reported for Inconel 718, and the results were used to successfully model the orthogonal cutting of Haynes 282, being a typical case of dynamic loading requiring previous characterization of the alloy.

    2016-01-01

    Full Text Available Stellite 6 was deposited by laser cladding on a P91 substrate with energy inputs of 1 kW (P91-1 and 1.8 kW (P91–1.8. The chemical compositions, microstructures and surface roughnesses of these coatings were characterized by atomic absorption spectroscopy, scanning electron microscopy and atomic force microscopy. The microhardness of the coatings was measured and the wear mechanism of the coatings was evaluated using a pin-on-plate (reciprocating wear testing machine. The results showed less cracking and pore development for Stellite 6 coatings applied to the P91 steel substrate with the lower heat input (P91–1. Further, the Stellite coating for P91-1 was significantly harder than that obtained for P91–1.8. The wear test results indicated that the weight loss for P91–1 was much lower than for P91–1.8. The surface topography data indicated that the surface roughness for P91-1 was much lower than for P91–1.8. The measurements of dilution and carbon content showed that P91–1 has lower dilution and higher concentration of carbon than P91–1.8. It is concluded that the lower hardness of the coating for P91–1.8, together with the softer underlying substrate structure, markedly reduced the wear resistance of the Stellite 6 coating and the lower hardness of the coating for P91-1.8 was due to higher level of dilution and lower concentration of carbon.

    The effects of cooling rate from annealing temperature, which simulated the diffusion bonding process, on the microstructure of Haynes 230 (Ni-22Cr-14W-5Co) were investigated. While the grain boundaries are slightly covered with Cr-rich M 23 C 6 carbides for the diffusion-bonded and quenched condition, precipitates were extensively present on/near the grain boundaries for the furnace-cooled specimens. For the furnace-cooled specimens, lamellar precipitates were extensively formed near the grain boundaries below 1 000 deg. C, with intervals of a few hundred nanometers. Also, grain boundaries were severely serrated for the furnace-cooled specimens. Through electron probe micro analysis and transmission electron microscope, the lamellar precipitates were identified as (Cr,W)-rich M 23 C 6 -type lamellar carbides. Despite the differences in microstructure, tensile properties were not much affected by the cooling rate. Creep tests are underway and results will be presented. (authors)

    From 1999 to 2006, a program was undertaken within the Materials Science and Technology Division, formerly the Metals and Ceramics Division, of Oak Ridge National Laboratory to characterize the tensile and creep-rupture properties of a newly produced heat of Haynes alloy 25 (L-605). Tensile properties from room temperature to 1100 C were evaluated for base material and welded joints aged up to 12,000 hours at 675 C. Creep and creep-rupture tests were conducted on base metal and cross-weldments from 650 to 950 C. Pressurized tubular creep tests were conducted to evaluate multiaxial creep-rupture response of the material. Over 800,000 hours of creep test data were generated during the test program with the longest rupture tests extending beyond 38,000 hours, and the longest creep-rate experiments exceeding 40,000 hours

    When the oil resources situation is taken into consideration, it is important to prepare now for the demand and supply situation of oil in the 21st century. The first method of the preparation is the noble-use of oil. The second method is the development and popularization of energies for transportation equipment which can take the place of petroleum. The candidates are synthetic liquid fuel, natural gas, and electricity (secondary batter). Methanol is the only synthetic liquid fuel which has the possibility of competing with petroleum both technologically and economically. By using methanol, cleaner combustion can be expected as compared with petroleum and coal. Methanol can be produced via synthetic gas not only from coal but also from natural gas, oil sand, oil shale, and biomass. From the technological point of view, innovation of quantity production technology of methanol is the first important subject. The second importance is the development of methanol vehicles and methanol fuel. Presently, methanol vehicles and fuels are in the stage of wide range and long-term verification test by running actual vehicles. 1 tab.

    Creep fatigue testing of Ni-based superalloy Inconel 617 and Haynes 230 were conducted in the air at 850 C. Tests were performed with fully reversed axial strain control at a total strain range of 0.5%, 1.0% or 1.5% and hold time at maximum tensile strain for 3, 10 or 30 min. In addition, two creep fatigue life prediction methods, i.e. linear damage summation and frequency-modified tensile hysteresis energy modeling, were evaluated and compared with experimental results. Under all creep fatigue tests, Haynes 230 performed better than Inconel 617. Compared to the low cycle fatigue life, the cycles to failure for both materials decreased under creep fatigue test conditions. Longer hold time at maximum tensile strain would cause a further reduction in both material creep fatigue life. The linear damage summation could predict the creep fatigue life of Inconel 617 for limited test conditions, but considerably underestimated the creep fatigue life of Haynes 230. In contrast, frequency-modified tensile hysteresis energy modeling showed promising creep fatigue life prediction results for both materials.

    Low-cycle fatigue deformation characteristics of HAYNES HR-120 alloy at room and high temperatures were studied under axial strain control. Test results show that there is a significant effect of test temperature on the low-cycle fatigue behavior of HAYNES HR-120 alloy. It was found that the alloy could cyclically harden at moderately high temperatures (649 C and 871 C), but generally cyclically soften at room temperature (24 C) and high temperature (982 C). However, the variation of the stress amplitude with cycles at the temperatures of 24 C and 982 C depended on the total strain range. The significant cyclic hardening of the alloy occurred at the high total strain ranges of 1.5% and 2.0% during the beginning state of the test at both 24C and 982 C. Microstructural analyses indicated that the cyclic hardening behavior of the alloy at the test temperature of 649 C could be related to the formation of a number of deformation bands. Nevertheless, increasing the test temperature to 871 C, cyclic hardening was attributed to the precipitation of secondary-phase particles. Furthermore, it was also found that the coarsening of secondary-phase particles brought about cyclic softening of the alloy at the high temperature of 982 C. Coffin-Manson equations and Holloman equations were given for HAYNES HR-120 alloy at different temperatures.

  19. Weldability of the superalloys Haynes 188 and Hastelloy X by Nd:YAG

    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.

    Analytical electron microscopy and spectroscopy analyses of the fusion zone (FZ) microstructure in autogenous laser beam welded Haynes 282 (HY 282) superalloy were performed. The micro-segregation patterns observed in the FZ indicate that Co, Cr and Al exhibited a nearly uniform distribution between the dendrite core and interdendritic regions while Ti and Mo were rejected into the interdendritic liquid during the weld solidification. Transmission electron diffraction analysis and energy dispersive X-ray microanalysis revealed the second phase particles formed along the FZ interdendritic region to be Ti-Mo rich MC-type carbide particles. Weld FZ solidification cracking, which is sometimes associated with the formation of {gamma}-{gamma}' eutectic in {gamma}' precipitation strengthened nickel-base superalloys, was not observed in the HY 282 superalloy. Modified primary solidification path due to carbon addition in the newly developed superalloy is used to explain preclusion of weld FZ solidification cracking in the material. - Highlights: Black-Right-Pointing-Pointer A newly developed superalloy was welded by CO{sub 2} laser beam joining technique.

    Phase I consisted of the primary decontamination, packaging, and shipment of all 241 Am-contaminated gloveboxes, vent system, and miscellaneous waste items located in the laboratory restricted area in the J.C. Haynes house. The primary goals of Phase I were to locate and account for a major quantity of 241 Am which was unaccounted for and to remove all radioactive materials and contamination posing an imminent hazard to public health and safety. All Phase I operations were conducted under a Quality Assurance (QA) Program Plan and QA procedures written specifically for this program. In addition, certain generic Battelle QA procedures were used for routine tasks. All operations were conducted under strict health physics supervision and procedures. Cognizant ORAU and US Nuclear Regulatory Commission (NRC) personnel were on site during the entire Phase I operation and provided support and approval in the daily operations. All staff members had participated in previous decontamination and decommissioning programs involving transuranic waste and completed Phase I in a well controlled, timely, and safe manner

    The biaxial thermal creep behavior of Inconel 617 and Haynes 230 at 850 and 950 °C was investigated. Biaxial stresses were generated using the pressurized tube technique. The detailed creep deformation and fracture mechanism have been studied. Creep curves for both alloys showed that tertiary creep accounts for a greater portion of the materials’ life, while secondary creep only accounts for a small portion. Fractographic examinations of the two alloys indicated that nucleation, growth, and coalescence of creep voids are the dominant micro-mechanisms for creep fracture. At 850 °C, alloy 230 has better creep resistance than alloy 617. When subjected to the biaxial stress state, the creep rupture life of the two alloys was considerably reduced when compared to the results obtained by uniaxial tensile creep tests. The Monkman–Grant relation proves to be a promising method for estimating the long-term creep life for alloy 617, whereas alloy 230 does not follow the relation. This might be associated with the significant changes in the microstructure of alloy 230 at high temperatures

    An experimental and simulation study of residual stresses was made in the vicinity of a gas tungsten arc weld, used to join a hemispherical end cap to a cylinder. The capped cylinder is used in a satellite application and was fabricated from a Co-based Haynes[reg] 25 alloy. The cylinder was 34.7 mm in outer diameter and 3.3 mm in thickness. The experimental measurements were made by neutron diffraction and the simulation used the implicit Marc finite element code. The experimental resolution was limited to approximately 3 mm parallel to the axis of the cylinder (the weld was 6 mm in the same direction) and comparison over the same volume of the finite element prediction showed general agreement. Subject to the limited spatial resolution, the largest experimentally measured tensile residual stress was 180 MPa, located at the middle of the weld. However, the predictions suggest that there are regions in the weld where average tensile residual stresses as much as 400 MPa exist. One qualitative disparity between the model and the experiments was that the measurement included a larger degree of asymmetry on either side of the weld than predicted by the model

    The results are reported of the chromosome analysis of 17 cases of acute myelocytic leukemia (AML), mostly belonging to M2 of the FAB classification, especially on the translocation t(8:21) and its variant translocations. The presence of two cases with simple variant translocation not involving No. 8 chromosome seems to suggest that No. 21 chromosome is more important to the genesis of AML than the No. 8 chromosome. This assumption appears to be supported by findings on cases with complex translocation: In two cases with complex translocation, the portion translocated from No. 21 chromosome onto No. 8 was firmly maintained in the specific site (q21) on No. 8 whereas the portion translocated from No. 8 chromosome onto No. 21 was involved in further translocation with another chromosome, onto which it was re-translocated. The results of the present cytogenetic study indicate that the analysis of variant translocations in various specific chromosome translocations in leukemia and other malignant disorders is very useful to elucidate the problem as to whether the genesis of such disorders lies in either one or both of the pair of chromosomes involved in the specific translocations of the respective diseases.

    Full Text Available The paper presents the research on the microstructure and mechanical properties of a pipe made of 16Mo3 steel, overlaid with superalloy based on Haynes NiCro625 nickel. The overlay weld was overlaid using the MIG (131 method. The performed macro - and microscopic tests have shown the correct structure of the overlay weld without any welding unconformities. The examined overlay weld was characterized by a dendritic structure of the primary crystals accumulating towards the heat removal. It has been proved that the content of iron in the surface zone does not exceed 7%, and the steel-superalloy joint shows the highest properties in comparison with the materials joined.

    2015-08-01

    The fatigue crack growth rates for nickel-based superalloy Haynes 282 were measured at temperatures of 550, 650, and 750 °C using compact tension specimens with a load ratio of 0.1 and cyclic loading frequencies of 25 Hz and 0.25 Hz. Increasing the temperature from 550 to 750 °C caused the fatigue crack growth rates to increase from ~20 to 60% depending upon the applied stress intensity level. The effect of reducing the applied loading frequency increased the fatigue crack growth rates from ~20 to 70%, also depending upon the applied stress intensity range. The crack path was observed to be transgranular for the temperatures and frequencies used during fatigue crack growth rate testing. At 750 °C, there were some indications of limited intergranular cracking excursions at both loading frequencies; however, the extent of intergranular crack growth was limited and the cause is not understood at this time.

    The effects of the electrical discharge alloying (EDA) process on improving the high temperature oxidation resistance of the Ni-based superalloy Haynes 230 have been investigated. The 85 at.% Al and 15 at.% Mo composite electrode provided the surface alloying materials. An Al-rich layer is produced on the surface of the EDA specimen alloyed with positive electrode polarity, whereas, many discontinuous piled layers are attached to the surface of the EDA superalloy when negative electrode polarity is selected. The oxidation resistance of the specimen alloyed with positive electrode polarity is better than that of the unalloyed superalloy, and the effective temperature of oxidation resistance of the alloyed layer can be achieved to 1100 o C. Conversely, the oxidation resistance of the other EDA specimen alloyed with negative electrode polarity is even worse than that of the unalloyed superalloy

    Full Text Available Um dos materiais utilizados para a adequação do meio bucal no serviço público é o cimento produzido a partir de óxido de zinco e eugenol. Entretanto, o eugenol é uma substância citotóxica que pode desencadear alguns efeitos adversos. Por essa razão, procura-se substituir o eugenol por uma substância que apresente baixa toxicidade, mantendo ou mesmo melhorando as propriedades do cimento. O óleo-resina de copaíba é um produto natural, utilizado pelas populações amazônicas e reconhecido por suas propriedades medicinais. Baseando-se nas propriedades desse óleo-resina, na ação antimicrobiana comprovada do hidróxido de cálcio e na ação anti-séptica do óxido de zinco, propôs-se formular um cimento odontológico obtido da associação do ZnO, Ca(OH2 e óleo-resina de Copaifera multijuga Hayne e avaliar sua atividade antibacteriana através do teste de diluição em meio líquido frente às cepas padrão de Streptococcus mutans (ATCC 25175 e S. sanguinis (ATCC 15300. Nesse ensaio, utilizaram-se os seguintes grupos experimentais: o cimento contendo ZnO, Ca(OH2 e óleo-resina de copaíba (G1 e cada um dos constituintes isoladamente, ZnO (G2, Ca(OH2 (G3 e óleo-resina de copaíba (G4. Todos os grupos analisados demonstraram atividade antibacteriana, o G4 apresentou os melhores resultados e o G1 mostrou-se um cimento promissor a ser utilizado em odontologia.

  5. Fibroblast growth factor 21 has no direct role in regulating fertility in female mice

    Full Text Available Objective: Reproduction is an energetically expensive process. Insufficient calorie reserves, signaled to the brain through peripheral signals such as leptin, suppress fertility. Recently, fibroblast growth factor 21 (FGF21 was implicated as a signal from the liver to the hypothalamus that directly inhibits the hypothalamic–gonadotropin axis during fasting and starvation. However, FGF21 itself increases metabolic rate and can induce weight loss, which suggests that the effects of FGF21 on fertility may not be direct and may reflect changes in energy balance. Methods: To address this important question, we evaluated fertility in several mouse models with elevated FGF21 levels including ketogenic diet fed mice, fasted mice, mice treated with exogenous FGF21 and transgenic mice over-expressing FGF21. Results: We find that ketogenic diet fed mice remain fertile despite significant elevation in serum FGF21 levels. Absence of FGF21 does not alter transient infertility induced by fasting. Centrally infused FGF21 does not suppress fertility despite its efficacy in inducing browning of inguinal white adipose tissue. Furthermore, a high fat diet (HFD can restore fertility of female FGF21-overexpressing mice, a model of growth restriction, even in the presence of supraphysiological serum FGF21 levels. Conclusions: We conclude that FGF21 is not a direct physiological regulator of fertility in mice. The infertility observed in FGF21 overexpressing mice is likely driven by the increased energy expenditure and consequent excess calorie requirements resulting from high FGF21 levels. Keywords: FGF21, Fertility, Leptin, Hypothalamic action

    Rozman, Kyle A.; Kruzic, Jamie J.; Sears, John S.; Hawk, Jeffrey A.

    2015-10-01

    The fatigue crack growth rates for nickel-based superalloy Haynes 282 were measured at 550, 650, and 750 °C using compact tension specimens with a load ratio of 0.1 and cyclic loading frequencies of 25 and 0.25 Hz. The crack path was observed to be primarily transgranular for all temperatures, and the observed effect of increasing temperature was to increase the fatigue crack growth rates. The activation energy associated with the increasing crack growth rates over these three temperatures was calculated less than 60 kJ/mol, which is significantly lower than typical creep or oxidation mechanisms; therefore, creep and oxidation cannot explain the increase in fatigue crack growth rates. Transmission electron microscopy was done on selected samples removed from the cyclic plastic zone, and a trend of decreasing dislocation density was observed with increasing temperature. Accordingly, the trend of increasing crack growth rates with increasing temperature was attributed to softening associated with thermally assisted cross slip and dislocation annihilation.

  16. Hydrogeology, hydraulic characteristics, and water-quality conditions in the surficial, Castle Hayne and Peedee aquifers of the greater New Hanover County area, North Carolina, 2012-13

    2014-01-01

    A major issue facing the greater New Hanover County, North Carolina, area is the increased demand for drinking water resources as a result of rapid growth. The principal sources of freshwater supply in the greater New Hanover County area are withdrawals of surface water from the Cape Fear River and groundwater from the underlying Castle Hayne and Peedee aquifers. Industrial, mining, irrigation, and aquaculture groundwater withdrawals increasingly compete with public-supply utilities for freshwater resources. Future population growth and economic expansion will require increased dependence on high-quality sources of fresh groundwater. An evaluation of the hydrogeology and water-quality conditions in the surficial, Castle Hayne, and Peedee aquifers was conducted in New Hanover, eastern Brunswick, and southern Pender Counties, North Carolina. A hydrogeologic framework was delineated by using a description of the geologic and hydrogeologic units that compose aquifers and their confining units. Current and historic water-level, water-quality, and water-isotope data were used to approximate the present boundary between freshwater and brackish water in the study area. Water-level data collected during August–September 2012 and March 2013 in the Castle Hayne aquifer show that recharge areas with the highest groundwater altitudes are located in central New Hanover County, and the lowest are located in a discharge area along the Atlantic Ocean. Between 1964 and 2012, groundwater levels in the Castle Hayne aquifer in central New Hanover County have rebounded by about 10 feet, but in the Pages Creek area groundwater levels declined in excess of 20 feet. In the Peedee aquifer, the August–September 2012 groundwater levels were affected by industrial withdrawals in north-central New Hanover County. Groundwater levels in the Peedee aquifer declined more than 20 feet between 1964 and 2012 in northeastern New Hanover County because of increased withdrawals. Vertical gradients

    Full Text Available Government Ordinance no. 107/1999 is a normative act with relevance in the field of consumer protection. Thus, according to Article 30, the ordinance is supplemented by GO no. 21/1992 on consumer protection. In this context, it should be noted that the notion of consumer as defined by GO no. 107/1999 is not identical to that used in consumer protection regulations. Thus, contracts for the sale of package travels may be contracts concluded with consumers from the perspective of GO no. 107/1999, but not from the point of view of consumer protection regulations. This study will identify the features of the consumer concept in GO no. 107/1999 and in GO no. 21/1992, as a normative act comprising the common law in the field of consumer protection. By identifying the differences between concepts, this study will exemplify their legal relevance in terms of consumer protection against the introduction of unfair contract terms.

    Full Text Available The aim of this work was to characterize the microstructure of the as-cast Haynes® 282® alloy. Observations and analyses were carried out using techniques such as X-ray diffraction (XRD, light microscopy (LM, scanning electron microscopy (SEM, transmission electron microscopy (TEM, X-ray spectroscopy (EDS, wave length dispersive X-ray spectroscopy (WDS, auger electron spectroscopy (AES and electron energy-loss spectrometry (EELS. The phases identified in the as-cast alloy include: γ (gamma matrix, γʹ (matrix strengthening phase, (TiMoCrC (primary carbide, TiN (primary nitride, σ (sigma-TCP phase, (TiMo2SC (carbosulphide and a lamellar constituent consisting of molybdenum and chromium rich secondary carbide phase together with γ phase. Within the dendrites the γʹ appears mostly in the form of spherical, nanometric precipitates (74 nm, while coarser (113 nm cubic γʹ precipitates are present in the interdendritic areas. Volume fraction content of the γʹ precipitates in the dendrites and interdendritic areas are 9.6% and 8.5%, respectively. Primary nitrides metallic nitrides (MN, are homogeneously dispersed in the as-cast microstructure, while primary carbides metallic carbides (MC, preferentially precipitate in interdendritic areas. Such preference is also observed in the case of globular σ phase. Lamellar constituents characterized as secondary carbides/γ phases were together with (TiMo2SC phase always observed adjacent to σ phase precipitates. Crystallographic relations were established in-between the MC, σ, secondary carbides and γ/γʹ matrix.

    Full Text Available This research reveals three causes of authority intersection in section 55 regulation Number 21, year 2008 on sharia banking. First, the transition of Religious Court after regulation Number 33 year 2006 on the changing of regulation Number 7 year 1989 on Religious Court  is  legalized.  Second,  there  is  an  image  that  General  Court  is  more  popular  than Religious Court. Third, there is socio-political influence and particular interests within the process of formulating the regulation. Judges in Religious Court of Malang are divided into two groups in interpreting section 55 regulation Number 21 year 2008 on Sharia Banking. Firstly, those who apply historical interpretation method argue that the section gives option towards dispute resolution forum. Secondly, those who apply grammatical method stated that section 55 is a historic, because the content has been included in section 49 Regulation Number 3 Year 2006 on the changing of Regulation Number 7 year 1989 on Religious Court which has implication towards the authority reduction of Religious Court on sharia banking.

    This work presents the Agenda 21 Local construction process developed by PETROBRAS within the context of the 'De Olho no Ambiente' Program. This is an alternative for the sustainable development of reduced social inclusion communities located in the Company's areas of influence in the Amazon Region. Agenda 21 is a participative process that analyzes a country, state, municipal or community's actual situation, and plans its sustainable future. Its objective is to reach a new development paradigm, through the construction of an action plan focused on a future scenario desired by the local community, which takes into consideration the vulnerability and potential analysis of its socio-economical, cultural and environmental bases. PETROBRAS has introduced Agenda 21 Local in three riverside communities located in the Coari municipal, where the Solimoes Terminal (TESOL) is situated. This terminal receives and stores petroleum and gas from the Urucu Petroliferous Province, in the Amazonian State. In each location partnerships were signed with several governmental and civilian institutions during the implementation of the Agenda 21 Local Forum. Here each participant has the right to debate, which makes this a participative management process mechanism and an act of citizenship. (author)

    Directory of Open Access Journals (Sweden)

    Pierpaolo Martino

    2017-01-01

    Full Text Available Il presente studio analizza Velvet Goldmine un film del 1998 diretto da Todd Haynes al fine di indagare come il regista americano riesca ad evidenziare la centralità del glam (emerso in Gran Bretagna nei primi anni Settanta nella cultura contemporanea, ponendo un' enfasi specifica sull’aspetto che più di ogni altro aveva caratterizzato quell’esperienza, ossia la sovversione parodica dell' idea di mascolinità normativa nei decenni precedenti. Sul palco i 'glamsters' – ossia artisti quali Bolan, Bowie, Roxy Music, Glitter – erano in grado, utilizzando segni visivi quali trucco e abiti 'glitter' di costruire un’identità di genere ibrida che si poneva in netto contrasto con il machismo di molti musicisti degli anni Sessanta. Seguendo un approccio metodologico in cui studi culturali, studi letterari e neo-musicologia finiscono per dialogare tra loro, la presente indagine crea uno stretto rapporto tra Oscar Wilde e la cultura glam – un rapporto individuato dal regista sin dalle prime battute del film – ma che qui viene declinato in un senso più specifico, in base al quale l' intero film rappresenta una parodia o reinvenzione glam dell'intera epopea wildiana e in cui le immagini e gli aforismi wildiani sembrano interrogare con la loro complessità e la loro portata dissacrante il nostro presente.  The present essay analyses Velvet Goldmine a 1998 film directed by Todd Haynes, in order to investigate how the American director points to the relevance of glam (emerged in Great Britain at the beginning of the Seventies within contemporary culture, focusing on one of its most relevant aspects, that is the parodic subversion  of the normative idea of masculinity which was dominant in the previous decades. Glamsters – that is, such artists as Bolan, Bowie, Roxy Music and Glitter – were able, using such visual signs as make-up and glitter dresses, to construct a hybrid gender identity, which sharply contrasted with the normative

    We have examined changes in Argonne Premium samples of Wyodak coal following 30 min treatment in liquid water at autogenous pressures at 150{degrees}, 250{degrees}, and 350{degrees}C. In most runs the coal was initially dried at 60{degrees}C/1 torr/20 hr. The changes were monitored by pyrolysis field ionization mass spectrometry (py-FIMS) operating at 2.5{degrees}C/min from ambient to 500{degrees}C. We recorded the volatility patterns of the coal tars evolved over that temperature range, and in all cases the tar yields were 25%--30% of the starting coal on mass basis. There was essentially no change after the 150{degrees}C treatment. Small increases in volatility were seen following the 250{degrees}C treatment, but major effects were seen in the 350{degrees} work. The tar quantity remained unchanged; however, the volatility increased so the temperature of half volatility for the as-received coal of 400{degrees}C was reduced to 340{degrees}C. Control runs with no water showed some thermal effect, but the net effect from the presence of liquid water was clearly evident. The composition was unchanged after the 150{degrees} and 250{degrees}C treatments, but the 350{degrees} treatment brought about a 30% loss of oxygen. The change corresponded to loss of the elements of water, although loss of ``OH`` seemed to fit the analysis data somewhat better. The water loss takes place both in the presence and in the absence of added water, but it is noteworthy that the loss in the hydrothermal runs occurs at p(H{sub 2}O) = 160 atm. We conclude that the process must involve the dehydration solely of chemically bound elements of water, the dehydration of catechol is a specific, likely candidate.

    Whether your interests lie in scientific arenas, the corporate world, or in government, you have certainly heard the praises of big data: Big data will give you new insights, allow you to become more efficient, and/or will solve your problems. While big data has had some outstanding successes, many are now beginning to see that it is not the Silver Bullet that it has been touted to be. Here our main concern is the overall impact of big data; the current manifestation of big data is constructing a Maginot Line in science in the 21st century. Big data is not "lots of data" as a phenomena anymore; The big data paradigm is putting the spirit of the Maginot Line into lots of data. Big data overall is disconnecting researchers and science challenges. We propose No-Boundary Thinking (NBT), applying no-boundary thinking in problem defining to address science challenges.

    Full Text Available Neste trabalho é relatado o esquema utilizado para obtenção da cultivar IAC 21 realizado durante o período de 1981/82 a 1993/94. A cultivar foi originada por resseleção da IAC 19, direcionada principalmente para resistência a Colletotrichum gossypii var. cephalosporioides e nematóides, através do melhoramento genealógico. No início dos estudos as seleções e respectivas progênies foram comparadas à cultivar original IAC 19 e, posteriormente, a 'IAC 20'. Além das características econômicas de produção e qualidade da fibra, a linhagem foi avaliada para resistência múltipla às doenças: murchas de Fusarium e Verticillium, mancha-angular, ramulose e nematóides. A cultivar IAC 21 foi superior a 'IAC 19' em 6,2%, em produtividade, na média geral dos experimentos, chegando a 18,1% em solos altamente infectados por patógenos; 4,6% em produção de sementes, 2,4% em tenacidade da fibra e 6,9% em tenacidade do fio, sem perdas significativas em outras características, com exceção da porcentagem de fibra que decresceu 2,6%. Com respeito às doenças, apresentou melhores índices para murcha de Fusarium e ramulose mantendo-se, entretanto, no mesmo nível para as demais. Estudos preliminares mostraram que 'IAC 21' apresentou índices inferiores a 'CNPA ITA 90' para a anomalia "murchamento avermelhado". Devido às vantagens verificadas em relação a 'IAC 19' e 'IAC 20', 'IAC 21' foi recomendada para plantio em todas as áreas do Estado de São Paulo, excluindo-se as de ocorrência do "murchamento avermelhado".

    Three Down syndrome patients for whom karyotypic analysis showed a mirror' (reverse tandem) duplication of chromosome 21 were studied by phenotypic, cytogenetic, and molecular methods. On high-resolution R-banding analysis performed in two cases, the size of the fusion 21q22.3 band was apparently less than twice the size of the normal 21q22.3, suggesting a partial deletion of distal 21q. The evaluation of eight chromosome 21 single-copy sequences of the 21q22 region - namely, SOD1, D21S15, D21S42, CRYA1, PFKL, CD18, COL6A1, and S100B - by a slot blot method showed in all three cases a partial deletion of 21q22.3 and partial monosomy. The translocation breakpoints were different in each patient, and in two cases the rearranged chromosome was found to be asymmetrical. The molecular definition of the monosomy 21 in each patient was, respectively, COL6A1-S100B, CD18-S100B, and PFKL-S100B. DNA polymorphism analysis indicated in all cases a homozygosity of the duplicated material. The duplicated region was maternal in two patients and paternal in one patient. These data suggest that the reverse tandem chromosomes did not result from a telomeric fusion between chromosomes 21 but from a translocation between sister chromatids. The phenotypes of these patients did not differ significantly from that of individuals with full trisomy 21, except in one case with large ears with an unfolded helix. The fact that monosomy of distal 21q22.3 in these patients resulted in a phenotype very similar to Down syndrome suggests that the duplication of the genes located in this part of chromosome 21 is not necessary for the pathogenesis of the Down syndrome features observed in these patients, including most of the facial and hand features, muscular hypotonia, cardiopathy of the Fallot tetralogy type, and part of the mental retardation. 54 refs., 5 figs., 3 tabs.

    THIS ISSUE FEATURES A VISUAL DEPICTION OF THE ACADEMY of Program and Project Leadership (APPL). I imagine a variety of initial reactions to the drawing. One might be, "What is a cartoon doing in a magazine about project management?" Or perhaps, "Wow, nice colors-and fun." Another may be to closely search the image for signs, symbols and meaning. Still another, to read a new level of innovation and creativity into the picture. Undoubtedly, some readers will raise questions about the cost. Of course, any reaction is a sign of engagement. The stronger, the more energized the emotional and cognitive processing, the better. It is a sign of attention and interaction. For I've heard it said, "You only need to worry if they don t care one way or the other." So what is the point of the picture? To stimulate interest, raise questions, promote discussion, and maybe raise a smile.. .That, at least, was my initial reaction when I was introduced to the work of Nancy Hegedus, who helps to create these drawings for Root Learning Inc. At the NASA PM Conference, I was first shown the work Nancy had been doing with the help of Goddard s Knowledge Management Architect, Dr. Ed Rogers. I was immediately drawn into the power of visualization as a tool for more effective learning, communicating, and conveying complex knowledge concepts. We need new tools in today s world, where information and data overwhelms by sheer volume. There are articles, pamphlets, communications, and white papers-all aiming to convince and influence. Reactions to these tend to be either avoidance or mind-numbing, heavy-eyed consent; the message never registers or enters the soul. That s one of the reasons that APPL s Knowledge Sharing Initiative (KSI) has turned to storytelling as a memorable way of transfer- ring knowledge, inspiring imitation of best practices, and spurring reflection. ASK Magazine s recent fourth birthday marks an important milestone in APPL s continuing quest to provide ongoing support to project managers and to promote mission success. And similar to storytelling, the power of visualization is receiving increasing attention in recent years as a way to stimulate engagement. Pictures and visual graphs are viewed as one of the most effective ways for displaying, describing, and generating discussion about quantitative and technically complex information. Prototypes, models, and simulations are considered essential for stimulating innovation through open and engaging discussions. There has also been extensive writing on the use of visual graphics, pictures, and cartoons to facilitate memory, creativity, openness, attention-and even well-being. For many of these reasons, I am excited to have a colorful visual depiction of the APPL world included in ASK. Without the addition of text or slides, the intent is to invite people into the world of the APPL mission-as well as its products, services, customers, and partners- in a fun and engaging manner. As project leaders strive to find ways to encourage engagement, learning, and transmission of knowledge, traditional technologies are proving to be as valuable as modern technologies. (But for those who want more information in the form of texts and slide presentations, we certainly have an abundance of those as well.)

    We study the effect of an external electric field on an exciton bound to an ionized donor (D{sup +}, X) confined in a spherical quantum dot using a perturbative-variational method where the wave function and energy are developed in series of powers of the electric field strength. After testing this new approach in the determination of the band gap for some semiconductor materials, we generalize it to the case of (D{sup +}, X) in the presence of the electric field and for several materials ZnO, PbSe, and InAs, with significant values of the mass ratio. Three interesting results can be deduced: First, we show that the present method allows to determine the ground state energy in the presence of a weak electric field in a simple way (E = E{sub 0} − αf{sup 2}) using the energy without electric field E{sub 0} and the polarizability α. The second point is that our theoretical predictions show that the polarizability of (D{sup +}, X) varies proportionally to R{sup 3.5} and follows an ordering α{sub D{sup 0}}<α{sub X}<α{sub (D{sup +},X)}. The last point to highlight is that the Haynes rule remains valid even in the presence of a weak electric field.

    We study the effect of an external electric field on an exciton bound to an ionized donor (D + , X) confined in a spherical quantum dot using a perturbative-variational method where the wave function and energy are developed in series of powers of the electric field strength. After testing this new approach in the determination of the band gap for some semiconductor materials, we generalize it to the case of (D + , X) in the presence of the electric field and for several materials ZnO, PbSe, and InAs, with significant values of the mass ratio. Three interesting results can be deduced: First, we show that the present method allows to determine the ground state energy in the presence of a weak electric field in a simple way (E = E 0  − αf 2 ) using the energy without electric field E 0 and the polarizability α. The second point is that our theoretical predictions show that the polarizability of (D + , X) varies proportionally to R 3.5 and follows an ordering α D 0 <α X <α (D + ,X) . The last point to highlight is that the Haynes rule remains valid even in the presence of a weak electric field

    The Ti-14Al-21Nb alloy called Super {alpha}{sub 2} is an alloy which has been improved of plastic transformation ability by adding Nb into Ti3Al with high specific strength, and is used for member materials in aircraft engines. In order to identify its oxidation characteristics, this paper discusses the oxidation characteristics under purified oxygen and atmospheric pressure in temperatures ranging from 1000 K to 1300 K. The experiment made a button-formed ingot with a diameter of 50 mm and a thickness of about 10 mm by melting and thermal refining, and used a thermobalance. Main conclusion thus obtained may be summarized as follows: the amount of increase due to oxidation after 100 ks oxidation at 1000 K is very small; oxidation between 1100 K and 1200 K follows nearly the parabolic rate laws; the scale consisted mainly of rutile, but a thin alumina concentration layer is formed; Nb is concentrated in the rutile-alumina mixed layer, and local fracture and regeneration are repeated at temperatures higher than 1300 K. 21 refs., 8 figs., 2 tabs.

    Serious shortage is predicted on cokes for blast furnaces in the first half of the 21st century. In order to deal flexibly with the fluid world market in the future, it is necessary to have a technology developed, by which coals from coking coal to non-coking dust coal can be used. The Japan Iron and Steel Federation and the Center for Coal Utilization, Japan are working on research and development of a new process with enhanced environmentality and economy (SCOPE 21) as a coke manufacturing process to respond to the requirements arisen from the above situation. The process is assessed basing on basic technological seeds such as rapid coal heating and high-speed carbonization and reformation of middle to low temperature cokes. The organizations are moving forward an eight-year development program which has started in fiscal 1994. This paper reports the summary of the development, and results of investigations and researches performed during fiscals 1994 and 1995. Rapid heating tests, middle to low temperature coke reformation tests, and tests for plug transportation of high-temperature coal have been performed. It has been verified, for example, that rapid coal heating can improve coke strength. The development work is being promoted toward grain size distribution and upscaling problems. 5 refs., 16 figs., 2 tabs.

    Full Text Available To reduce the recovery or the replacement costs of diesel engine exhaust valves, they are manufactured with an economic base material, and a coating which is deposited on the seat valve in order to reach high hardness and good impact, corrosion and high temperature wear resistance (>550 °C and without lubrication. In this work, appropriate laser cladding parameters have been determined to obtain Stellite 6 coatings over AISI 304 steel (as plane test specimens and SAE EV8 steel (as valves substrates. One and two superimposed tracks were deposited on the seat valves, and modifying the laser power as a function of the rotated angle at the beginning and the end of the circular tracks, pores and cracks have been minimized and the thickness of the track were made uniform. Hardness, dilution and final microstructure of the different coatings have been analysed. A 10 % dilution and 550 HV in the tracks over plane test specimens was observed, while valves with one track showed 25 % and 430 HV respectively. With two superimposed tracks the hardness was up to 470 HV in the upper track.

    Para abaratar el coste de recuperación o sustitución de válvulas de escape en motores diesel, estas se fabrican con un material base económico, recubriéndose el asiento de la válvula con otro material al que se exigirá elevada dureza y buena resistencia al impacto, a la corrosión y al desgaste erosivo en caliente (>550 °C y sin lubricación. Partiendo de esta idea, en el presente trabajo se han determinado los parámetros adecuados para realizar, mediante la técnica de plaqueado láser, un recubrimiento con Stellite 6, sobre sustratos de acero AISI 304 (probetas planas y SAE EV8 (válvulas reales. Sobre las válvulas, se depositaron uno y dos cordones superpuestos, se minimizó la presencia de poros y grietas, modificando el grado de solape inicial y final de los cordones circulares y la potencia en función del ángulo girado.

    The Paris Agreement provides a clear signal and a solid framework for climate action. Balanced and ambitious in its objectives - including full decarbonization of the global economy before the end of the century - it has all the conditions to encourage everyone to do more. In establishing a new international climate change regime, the Agreement focuses on the essentials: guiding countries towards low-carbon and climate resilient economies. The main challenge resides not in the direct implementation of the decisions taken in Paris, but rather in the alignment of countries' national strategies with a decarbonization trajectory. COP21 marks the advent of a new regime of international cooperation rather than a 'utopian' and politically unpalatable system to punish or coerce States to take action. It confirms the desire to engage both State and non-State actors on climate action. In this respect, it is a real victory of multilateralism. Indeed, COP21 marks the 'end of the beginning' of a long negotiations process to shift to a permanent regime, completed by regular appointments to boost ambition. This victory, however, will become historical only if this cooperation leads to enhanced action and concrete results. And this is where the hard work begins

    Hymenaea stigonocarpa is a deciduous and monoecious Neotropical tree species pollinated by bats. Due to overexploitation and habitat destruction, the population size has drastically diminished in nature. No previous study has investigated Mendelian inheritance, linkage, and genotypic disequilibrium in the available microsatellite markers in this species. So, our aim was to estimate these parameters using six microsatellite loci in a sample of 470 adults and 219 juveniles from two populations of H. stigonocarpa. In addition, 30 seeds per tree from 35 seed-trees were collected. Each seed was kept record of the seed-trees and fruit origin. Based on the six microsatellite loci, we found that only 10.6% of the cases showed significant deviations from Mendelian segregation and 15.3% showed linkage. We detected no evidence of genotypic disequilibrium between the loci in the adult trees or juveniles. Thus, our results suggest that these loci can be used with great accuracy in future genetic analyses of H. stigonocarpa populations.

    This report presents a descriptive plan of tests for the 21-Rod Bundle Flow Blockage Task of the Full-Length Emergency Cooling Heat Transfer Separate Effects and Systems Effects Test Program (FLECHT SEASET). This task will consist of forced and gravity reflooding tests utilizing electrical heater rods to simulate PWR nuclear core fuel rod arrays. All tests will be performed with a cosine axial power profile. These tests are planned to be used to determine effects of various flow blockage configurations (shapes and distributions) on reflooding behavior, to aid in development/assessment of computational models in predicting reflooding behavior of flow blockage configurations, and to screen flow blockage configurations for future 161-rod flow blockage bundle tests

    Sphagnum moss was collected from 21 ombrotrophic (rain-fed) peat bogs surrounding open pit mines and upgrading facilities of Athabasca bituminous sands in Alberta (AB). In comparison to contemporary Sphagnum moss from four bogs in rural locations of southern Germany (DE), the AB mosses yielded lower concentrations of Ag, Cd, Ni, Pb, Sb, and Tl, similar concentrations of Mo, but greater concentrations of Ba, Th, and V. Except for V, in comparison to the "cleanest", ancient peat samples ever tested from the northern hemisphere (ca. 6000-9000 years old), the concentrations of each of these metals in the AB mosses are within a factor of 3 of "natural, background" values. The concentrations of "heavy metals" in the mosses, however, are proportional to the concentration of Th (a conservative, lithophile element) and, therefore, contributed to the plants primarily in the form of mineral dust particles. Vanadium, the single most abundant trace metal in bitumen, is the only anomaly: in the AB mosses, V exceeds that of ancient peat by a factor of 6; it is therefore enriched in the mosses, relative to Th, by a factor of 2. In comparison to the surface layer of peat cores collected in recent years from across Canada, from British Columbia to New Brunswick, the Pb concentrations in the mosses from AB are far lower.

Por outro lado, amplifica o conceito de desenvolvimento como uma "boa qualidade de vida em tremos de alimentação, habitação, educação e saúde, seguridade social, recreação, segurança e liberdade". A relação entre desenvolvimento e saúde está associada com os recursos e meios naturais e artificiais e com os comportamentos da população humana, tais como crescimento populacional, aglomeração e migrações. O homem é "hóspede da natureza e vítima de si próprio". Embora a Conferência de Alma-Ata de 1978 tenha previsto "Saúde para todos no ano 2000", a saúde do mundo piorou na última década devido à crise econômica na América Latina, Ásia e África.

    Two major alloys used for orthopedic implants are 316L stainless steel and a cast cobalt--chromium--molybdenum alloy similar to Haynes Stellite 21. Another alloy that is just being introduced is Ti--6Al--4V. All three of these alloys are used in different conditions with different microstructures. Standard specimens with typical microstructures encountered in orthopedic applications were loaded to fracture in both overload and fatigue modes. Different rates of loading were also used in some cases. The fracture surfaces of these standard samples were analyzed in the Scanning Electron Microscope. An attempt was made to relate the fracture behavior, as evidenced by the fracture typography, to the microstructure of the alloy as revealed by metallography

    This work presents the Agenda 21 Local construction process developed by PETROBRAS within the context of the 'De Olho no Ambiente' Program. This is an alternative for the sustainable development of reduced social inclusion communities located in the Company's areas of influence in the Amazon Region. Agenda 21 is a participative process that analyzes a country, state, municipal or community's actual situation, and plans its sustainable future. Its objective is to reach a new development paradigm, through the construction of an action plan focused on a future scenario desired by the local community, which takes into consideration the vulnerability and potential analysis of its socio-economical, cultural and environmental bases. PETROBRAS has introduced Agenda 21 Local in three riverside communities located in the Coari municipal, where the Solimoes Terminal (TESOL) is situated. This terminal receives and stores petroleum and gas from the Urucu Petroliferous Province, in the Amazonian State. In each location partnerships were signed with several governmental and civilian institutions during the implementation of the Agenda 21 Local Forum. Here each participant has the right to debate, which makes this a participative management process mechanism and an act of citizenship. (author)

    The follow-up of cohorts of adults from more than 20 European centres of the former ECRHS I (1989-1992) investigates long-term effects of exposure to ambient air pollution on respiratory health, in particular asthma and change of pulmonary function. Since PM 2.5 is not routinely monitored in Europe, we measured PM 2.5 concentrations in 21 participating centres to estimate 'background' exposure in these cities. Winter (November-February), summer (May-August) and annual mean (all months) values of PM 2.5 were determined from measuring periods between June 2000 and November 2001. Sampling was conducted for 7 days per month for a year. Annual and winter mean concentrations of PM 2.5 vary substantially being lowest in Iceland and highest in centres in Northern Italy. Annual mean concentrations ranged from 3.7 to 44.9 μg m -3, winter mean concentrations from 4.8 to 69.2 μg m -3, and summer mean concentrations from 3.3 to 23.1 μg m -3. Seasonal variability occurred but did not follow the same pattern across all centres. Therefore, ranking of centres varied from summer to winter. Simultaneously, NO 2 concentrations were measured using passive sampling tubes. Annual mean NO 2 concentrations range from 4.9 to 72.1 μg m -3 with similar seasonal variations across centres and constant ranking of centres between seasons. The correlation between annual NO 2 and PM 2.5 concentrations is fair (Spearman correlation coefficient rs=0.75), but when considered as monthly means the correlation is far less consistent and varies substantially between centres. The range of PM 2.5 mass concentrations obtained in ECRHS II is larger than in other current cohort studies on long-term effects of air pollution. This substantial variation in PM 2.5 exposure will improve statistical power in future multi-level health analyses and to some degree may compensate for the lack of information on within-city variability. Seasonal means may be used to indicate potential differences in the toxicity

    resources would entail targeted use of the 21-gene expression assay.OBJETIVO: O índice de recorrência (IR, também conhecido como painel de 21 genes, pode apoiar decisões com relação ao uso de quimioterapia (QT no câncer de mama precoce. Procuramos investigar o impacto potencial da incorporação do IR na prática privada no Brasil, a partir da perspectiva das fontes pagadoras. MÉTODOS: Conduzimos uma pesquisa com 30 oncologistas brasileiros (de um total de aproximadamente 700, que foram estratificados por Estado de acordo com a proporção de pacientes com câncer de mama e com cobertura pelo sistema de saúde suplementar. Avaliamos o tratamento de primeira escolha para pacientes com câncer de mama com axila negativa e expressão positiva do receptor de estrógeno, independente do estado menopausal. Os entrevistados não estavam cientes do objetivo do estudo. As respostas permitiram uma avaliação quantitativa dos padrões de cuidado, considerando o uso de diferentes regimes de QT, o tipo de pré-medicações, o uso de fatores de crescimento e o tratamento hospitalar da neutropenia febril. Calculamos o custo dos medicamentos usando o Brasíndice, e o custo do IR foi fixado em R$ 3.900,00 (MammaGene®. Outras despesas médicas diretas, custos médicos indiretos e custos não-médicos não foram considerados. RESULTADOS: Numa corte hipotética de 100 pacientes sem acesso ao teste de IR, 84 iriam receber quimioterapia. Reclassificando a elegibilidade das pacientes para QT de acordo com o IR, esse número cairia para 49. Para uma coorte hipotética de 100 pacientes com acesso ao IR, seriam economizados R$ 134.915,00 em despesas médicas diretas. CONCLUSÃO: Considerando o preço atual para avaliação do IR no Brasil, nossa análise econômica sugere que este teste economizaria custos, pela perspectiva das fontes pagadoras do setor privado. Além disso, o uso otimizado de recursos poderia requerer o emprego do painel de 21 genes de forma racional.

    Elaboration of the action plan for the New Earth 21 plan proposed by Japan in Houston Summit was researched. In fiscal 1995 three types of energy supply/demand scenarios, sensitivity analysis under various conditions, and cases presupposing CO2 emission regulations or not were evaluated by analysis toward 2050 using the New Earth 21 Model (NE 21 Model). Energy-saving is important, and CO2 recovery/treatment technology is introduced according to CO2 emission regulations, while attention is focussed on biomass energy. The issue of solar and wind power generation is cost reduction. In a presupposed horizontally integrated energy system, methanol represents an important intermediate energy. As a whole, CO2 reduction can be achieved by various combinations of energy-saving, introduction of regenerative energy, and CO2 recovery/treatment technology. Case studies of the action plan were conducted by unifying the evaluation criterion on coal IGCC, photovoltaic generation and biomass. The NE 21 Model was useful for elaboration of the reduction scenarios of CO2 emission. 26 refs., 84 figs., 28 tabs.

    It is necessary to establish scenarios for reducing CO2 emissions and for developing CO2 emission control technologies to obtain a global consensus, using appropriate analytical models. For modification of the DNE-21 (Dynamic New Earth 21) model, it has a category designated as innovative technologies not involving CO2 emission and an optional consideration for the absorption of atmospheric CO2 by biomass. A global carbon circulation model, including vegetation in its scope, is also incorporated. Major results of the simulation are shown. When 20% reduction in CO2 emissions is required for only OECD countries after the year 2020, it has been demonstrated that CO2 concentration in the atmosphere will reach as high as about 900 ppm in 2100 due to CO2 emission by developing countries, and will not be a tolerable level. Under the condition that CO2 concentration in the atmosphere is controlled at 450 ppm in 2100, the amount of renewable source of energy from photovoltaic power generation and biomass will increase and technologies of CO2 recovery and storage will decrease. Research and development of the production of methanol from recovered CO2 will be adopted as innovative technology for CO2 measures. 69 refs., 112 figs., 79 tabs.

    For the purpose of developing the white light-emitting diode (LEDs) lightening as 'a plan on lighting for the 21st century,' the results of the following R and D were obtained: 1) basic study of light-emitting mechanism; 2) improvement of epitaxial growth method of blue/ultraviolet LED; 3) substrate for homoepitaxial growth; 4) basic characteristics of phosphor-based light source for white LED lighting. In 1), light emitting mechanisms responsible for high-quantum efficiency of InGaN mixed semiconductors and InGaN/GaN quantum wells were studied by means of temperature-dependent photoluminescence (PL), time-resolved PL and selective-excitation PL spectroscopy. In 2), precise lapping and polishing procedures of sapphire and GaN crystalline substrates for epitaxial growth using metalorganic chemical-vapor-deposition and MBE showed favorable surface characteristics of substrates. In 3), study was made on growth conditions and growth mechanism of GaN bulk single crystals using the nitrogen pressure-controlled solution growth method. A size of 12mm diameter of GaN single crystal showing good crystallinity and PL characteristics were obtained. In 4), excitation, absorption and PL spectra of rare-earth doped Y{sub 2}O{sub 2}S red phosphor were studied in detail. (NEDO)

    Short VNTR alleles that go undetected after conventional Southern blot hybridization may constitute an alternative explanation for the heterozygosity deficiency observed at some minisatellite loci. To examine this hypothesis, we have employed a screening procedure based on PCR amplification of those individuals classified as homozygotes in our databases for the loci D1S7, D7S21, and D12S11. The results obtained indicate that the frequency of these short alleles is related to the heterozygosity deficiency observed. For the most polymorphic locus, D1S7, {approximately}60% of those individuals previously classified as homozygotes were in fact heterozygotes for a short allele. After the inclusion of these new alleles, the agreement between observed and expected heterozygosity, along with other statistical tests employed, provide additional evidence for lack of population substructuring. Comparisons of allele frequency distributions reveal greater differences between racial groups than between closely related populations. 45 refs., 3 figs., 6 tabs.

    Full Text Available Diversos episódios e evoluções recentes mostram a adesão de setores tradicionais e novos das elites brasileiras ao predomínio das finanças e de suas razões na sociedade brasileira. A partir da análise do engendramento e da difusão da governança corporativa e dos fundos de private equities na acepção que elas vêm ganhando no Brasil, podemos mesmo falar de convergência das elites em torno dos mecanismos criados para a medição financeira, ainda que o resultado ocorra por meio de um alargamento de sua polissemia. Esses mecanismos, para cá trazidos no intuito explícito de acelerar e facilitar a integração das empresas brasileiras ao espaço e à lógica que impera nos mercados financeiros, avançam rapidamente, mas acabam recebendo um significado menos hardcore do que os financistas esperam. Ainda que deploráveis para os financistas ortodoxos, esses resultados dificilmente surpreenderiam um cientista social treinado. É por intermédio da polissemia que as abóboras se ajeitam na carroça da sociedade em movimento. A análise desse diálogo social produzido em torno das questões financeiras se torna assim uma excelente janela para a compreensão não só das disputas econômicas, mas também das disputas políticas que sacodem a sociedade brasileira contemporânea.Various recent episodes and evolutions demonstrate how both traditional and new sectors of the Brazilian elite have embraced the dominance of finance and its logic in Brazilian society. An analysis of the creation and diffusion of corporate governance and private equity funds - in the sense these have acquired in Brazil - allows us to identify a convergence of the country's elite sectors in terms of the mechanisms created for financial measurement, although this outcome stems from a broadening of their polysemy.

Para realizar tal intento, valeu-se de uma pesquisa qualitativa de abordagem documental, que se realizou por meio de consultas a legislações, ordenamentos legais e documentos produzidos por organismos nacionais e internacionais referentes à educação, especialmente a de nível superior. Também foi realizada pesquisa de caráter bibliográfico, baseada em autores como Cury (2002, Ferreira e Oliveira (2011, Höfling (2001, Mancebo (2004, Sguissardi (2009, Silva Jr. e Sguissardi (2001, 2005 e outros, com vistas a buscar contribuições teóricas referenciadas para a compreensão da temática apresentada. Como resultado, este estudo aponta que a educação superior avança em conformidade com demandas do Estado, do mercado, e da própria sociedade civil. Por assim ser, as políticas públicas voltadas para esse nível de ensino revelam traços dos conflitos de interesses desses diversos atores, e por isso, não são neutras, mas perpassadas pelos valores e objetivos de cada um.

    Full Text Available O experimento foi realizado com o objetivo de avaliar a utilização de cinco níveis de açúcar de cana (0; 4; 8; 16 e 32% em substituição ao milho na alimentação de frangos de corte no período de 1 a 21 dias. Trezentos e vinte pintos, metade de cada sexo, foram distribuídos casualmente em 20 boxes, com total de 16 aves/boxe. As aves receberam água e ração à vontade durante toda a fase de criação, sendo as rações isoprotéicas e isocalóricas. Aos 42 dias de idade, as aves foram pesadas e quatro aves de cada unidade experimental, dois machos e duas fêmeas, foram submetidas a um jejum de 12 horas para posterior abate e evisceração, quando foram avaliados peso e rendimento de carcaça e cortes nobres. Observou-se redução linear no ganho de peso e piora para conversão alimentar com o aumento dos níveis de açúcar, demonstrando menor eficiência de utilização do alimento. Com relação aos cortes, não houve efeito significativo para as fêmeas. Nos machos foi observado efeito quadrático para peso de carcaça, sendo o melhor nível estimado em 8,42%, alcançando o máximo de 1965,1 g. A análise econômica não demonstrou vantagens na utilização do açúcar.The experiment was carried out to evaluate the use of five levels of sugar (0; 4; 8; 16 and 32% in substitution to the corn in the feed of broilers from 1 to 21 days.

    As the research study contributing to implementation of 'The New Earth 21' proposed by Japan at the Houston Summit in 1990, a DNE21 model was developed as a quantitative assessment model for global warming preventive technology, heightening of efficiency of the global energy supply/demand system, conversion to energy sources of low carbon emissions, etc. In the project of 'The New Earth 21,' economy and environment can be compatible centering on developed countries' technical development and technology transfer to developing countries. In FY 2000, for heightening applicability of the DNE21 model, the world, which was used to be divided into 10 regions, was divided into 54. At the same time, a prototype model was constructed in which cities in the region were divided into three cities: large; medium; small. Using the DNE21 model, evaluation was made of effects of uncertainties such as population, economic growth, final energy demand and cost as preconditions of the model on the optimization of global warming preventive measures. Further, technologies which are expected to be important for global environmental policy in the ultra-long term were listed up to estimate the potentiality. (NEDO)

    For the establishment of a CO2 measures introduction scenario which the world would accept, the latest information was collected, the DNE21 (Dynamic New Earth 21) model was improved, and simulation was reviewed. In fiscal 1998, simulation was performed for each district using an LDNE21 (Linear Dynamic New Earth 21) model, and an energy flow chart, energy balance table, and trade table were prepared and subjected to detailed deliberation. Studied were also conducted about the changes to occur in methanol production when the natural gas reserves and plant cost data were given different values. In the DNE21 model, the 'macro economy model' and 'warming damage function' were integrated, and simulation was performed for verification. Using a standard model compatible with COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change), comparison was made between a case in which different CO2 emission constraints were imposed on the advanced area and developing area separately and a case in which one and the same constraint was imposed on the world as a whole, and calculations were made about CDM (Clean Development Mechanism).

    Japan proposed in the Houston Summit the New Earth 21 to be carried out with technology development and technology transfer, and to make a concrete development of the project, Japan also proposed in the Tokyo Summit a TREE Plan for working out comprehensive strategies of the innovative technology development. In the CO3 Kyoto Conference in 1997, numerical targets for developed countries were determined which have legal binding force for control/reduction of greenhouse gas emissions in the term of 2008-2012. It was agreed to urge developing countries also to play a certain part in the project through the clean development. Therefore, the paper made quantitative analysis of important CO2 prevention technologies, technology transfer costs, and economical assessment by energy conservation. As a model, the DNE 21 model was upgraded and used into which CO2 prevention technologies, energy, economy and climate changes were integrated. In fiscal 1997, the following were carried out: collection of data on important CO2 prevention technologies and systems and analytical assessment using the DNE 21 model, CO2 reduction and selection of energy technology, assessment of energy system costs, construction of the unified DNE 21 model, and opening of the international workshop. 62 refs., 98 figs., 34 tabs.

    Full Text Available INTRODUCTION: This article serves as a "call to action" for physical therapists in the 21st century with special attention to the needs of Brazilians. Compared with evidence-based practice supporting the use of specific interventions, practice that is informed by contemporary societal and Health priorities has seriously lagged behind over recent decades. "The First Physical Therapy Summit on Global Health" held at the 2007 World Congress of the World Confederation of Physical Therapy (WCPT in Canada highlighted the discrepancy between current practice trends globally and contemporary definitions of Physical Therapy (that subsume words such as health, well-being, quality of life, health promotion and prevention; the leading Health priorities within the WCPT regions; the proportions of physical therapists practicing in these priority areas; and the proportions of entry-level Physical Therapy professional education devoted to them. In the 20th century, the profession strived to align itself with societal needs, for example the world wars and poliomyelitis epidemics. Over the past 50 years, lifestyle conditions including ischemic heart disease, smoking-related conditions, hypertension, stroke, obesity, diabetes and cancer have predominated. Despite a remarkable shift from communicable diseases to non-communicable conditions over the past century, the profile of lifestyle conditions within professional practice and education remains low and disproportional to need. This is particularly striking given the unequivocal data in the literature that supports the cost-benefit relationship of noninvasive interventions (primarily Health education and exercise over the short and long-term, with regard to their prevention, "cure" and management. Often the outcomes from these simple inexpensive interventions for lifestyle conditions are superior to drugs and surgery, which are largely used to mitigate signs and symptoms rather than to address underlying causes

    Full Text Available A compreensão do mundo contemporâneo exige um olhar naturalista do qual a obra de Josué de Castro é uma das mais importantes expressões: pensar de maneira articulada a vida social e a reprodução do ambiente natural em que se apóia - incluindo aí a natureza do próprio homem, seu corpo - é a pedra de toque do método geográfico praticado em Geografia da Fome. Esse método é importante não apenas para estudar aquelas regiões onde a fome se abate severamente sobre a vida da população, mas oferece uma importante chave de leitura dos problemas alimentares que se anunciam para o século XXI, quando a população mundial deverá ter um aumento de quase 50%. Os desafios produtivos dos próximos anos - que este artigo procura expor de maneira sumária - não poderão ser enfrentados com base nas técnicas que caracterizaram a Revolução Verde. Eles exigem uma compreensão refinada dos vínculos entre sistemas sociais e sistemas ecológicos, para a qual a obra de Josué de Castro é uma inspiração fundamental.Understanding the contemporary world requires a naturalist view, wherein the work of Josué de Castro is one of the most important expressions: taking a comprehensive approach to social life and reproduction of the natural environment that supports it - including the nature of humans themselves, their bodies - is the cornerstone of the geographic method practiced in Geografia da Fome [The Geography of Hunger]. This method is important for studying regions where hunger severely afflicts the populations, and also offers an important key for interpreting the food problems that are forecast for the 21st century, when the world population is expected to increase by nearly 50%. The food production challenges in the coming years - and which this article discusses briefly - cannot be solved with the techniques that characterized the so-called Green Revolution. Rather, they require a more refined understanding of the links between the

  7. Hacia una nueva seguridad social en el siglo XXI: sin solidaridad en el financiamiento no habrá universalidad Toward new social security systems in the 21st century: universal coverage is impossible without cohesion in financing

    2000-08-01

    Full Text Available En los países de América Latina y el Caribe, los sistemas de seguridad social siempre han estado bajo la responsabilidad casi exclusiva del sector público y han presentado importantes deficiencias, tales como bajas tasas de cobertura, desequilibrios financieros e inadecuada asignación y gestión de los recursos. Para tratar de solucionar estos problemas y enfrentar el aumento de la demanda asociado con la transición demográfica y epidemiológica de la población, varios países han iniciado durante la década de los noventa procesos de reforma de sus sistemas de seguridad social que se han caracterizado por tres rasgos fundamentales: a búsqueda de un mayor vínculo entre contribuciones y beneficios para lograr mayor equilibrio entre ingresos y gastos; b cambios en la composición pública-privada que permitan una mayor presencia de agentes privados en el financiamiento y la provisión de servicios, y c énfasis en los mecanismos de mercado como medio para promover la eficiencia en la utilización de los recursos, asignando al Estado un papel regulador y de garante de beneficios básicos a grupos que, por su condición socioeconómica, no logran ciertos niveles mínimos de aporte. Este trabajo examina algunos de los problemas que han planteado las reformas realizadas hasta ahora y las lecciones que de ellas se pueden extraer, analiza la relación entre universalidad y solidaridad, y plantea que el principal desafío de las reformas de la seguridad social es el avance hacia sistemas de carácter universal que amplíen significativamente la cobertura poblacional, para lo cual es inevitable fortalecer los mecanismos de solidaridad en el financiamiento y mejorar la eficiencia mediante la introducción de instrumentos de mercado que no afecten negativamente al componente solidario en el ámbito del financiamiento. Se concluye que es necesario aumentar los niveles de cobertura, mejorar la gestión, preocuparse por el diseño de la composición p

    Full Text Available In this study the characteristics of the vertical structure of an episode of Low Level Jets (LLJ occurring in the coast of Para is described. Radiosonde data of Ajuruteua city in Bragança collected during the DESMATA Experiment (Impact of the Deforestation the Atlantic Coast of the Amazonian, taking place in 2002, from April 08th to 22th, are used. Among the detected cases during the rainy period, one specific case with 12 hours duration, average velocity of 15m/s and directed from NE to E in the point of maximum velocity was selected. The observational results have indicated that this LLJ located in the coast of Para was due to the combined action of two factors: (1 inertial oscillation and (2 superficial baroclinicity. These two combined factors sustained this LLJ with velocities between 10 and 13m/s during the day and between 14 and 16m/s during the night, at an average altitude of 800m above surface.Neste estudo descreve-se as características da estrutura vertical de um episódio de Jatos de Baixos Níveis (JBN ocorrido no litoral do Pará, utilizando-se para tal, dados das radiossondagens de Ajuruteua, Município de Bragança coletados durante o experimento DESMATA (Impacto do Desmatamento Junto ao Litoral Atlântico da Amazônia realizado no período de 08 a 22 de abril de 2002. Dentre os casos detectados no período chuvoso, selecionou-se um que se manteve por 12 horas com velocidade média de 15m/s e que estava direcionado de Nordeste para Leste, no ponto de máxima velocidade. Os resultados observacionais indicaram que, este JBN localizado no litoral Paraense foi resultado da ação combinada de dois fatores: (1 oscilação inercial e (2 baroclinia superficial. Estes dois fatores combinados sustentaram este JBN com intensidades entre 10 e 13m/s durante o dia e entre 14 e 16m/s durante a noite, localizado a uma altitude média de 800m acima da superfície.

    Full Text Available Resumo Tambor de Mina é o nome da religião afro-brasileira no Maranhão e na Amazônia estabelecida a partir de São Luís desde meados do século XIX. Existem duas casas fundadas por africanos que se continuam: a Casa das Minas Jeje, de origem daomeana e a Casa de Nagô, iorubana de onde derivam a maioria dos terreiros de Mina recentes e atuantes. Trata-se de religião muito ritualizada e discreta, envolvida em segredos e mistérios cuja mitologia é pouco comentada e os rituais muito desenvolvidos. As religiões afro-brasileiras se caracterizam pela realização de festas com transe, danças e comidas que atraem muitos participantes. A comida é bastante para oferecer a todos e distribuir as sobras. A fartura nas festas maiores constitui um dos elementos de prestígio das casas. O texto baseia-se em entrevistas com líderes de um terreiro antigo e de duas casas recentes, sobre comida de santo nas festas. Na linguagem de Mauss o sacrifício constitui obrigação que estabelece uma comunicação entre o mundo sagrado e o profano. O preparo e o consumo da comida de santo permitem conhecer aspectos do sincretismo e dos simbolismos nos rituais. Palavras-chave: Religiões afro-brasileiras; comida de santo; sincretismo; festas; ritual.   Abstract Tambor de Mina is the name of the Afro-Brazilian religion in Maranhão and Amazon established in São Luís (capital of Maranhão state since the mid-nineteenth century. There are two matrix-houses founded by Africans: Casa das Minas Jeje, a Dahomean origin house and Casa de Nagô, originally Yoruba and from which most of the Tambor de Mina's houses come from. It is a very ritualized and discrete religion, involved in secrets and mysteries whose mythology is not frequently commented upon and its rituals are highly developed. Afro-Brazilian religions are characterized by the performance of parties with trance, dance and food which attract many participants.  Food is enough to be offered to everyone and

    We present here a 78-year-old female patient with acute myeloid leukemia (AML), French-American-British classification M2, exhibiting isodicentric chromosome 21, idic(21)(q22), at the time of diagnosis. The patient had three idic(21)(q22), besides the del(5)(q13q32), add(21)(q22), dic(21;22) (q22;q13), and +22. Fluorescence in situ hybridization studies with whole-chromosome painting and centromere-specific probes for chromosome 21 verified the diagnosis of idic(21)(q22). There were no distinct clinicohematological characteristics of AML with isodicentric 21. The patient was treated with remission-induction therapy followed by consolidation therapy. Two years later, the patient showed the disappearance of isodicentric 21 but retained del(5)(q13q32) and gained other chromosomal abnormalities, +add(17)(p11) and -16. To our knowledge, this is the first report of AML with acquired idic(21)(q22).

  10. White Paper No 21 (2011-2012). Norwegian Climate Policy

    International Nuclear Information System (INIS)

    2012-01-01

    The Norwegian Government intends to take a number of steps to reduce greenhouse gas emissions and promote technological advances. Some of the most important are: establishing a new climate and energy fund, raising the CO 2 tax rate for the offshore industry, and improving public transport. The white paper keeps to the targets set out in the 2008 agreement on climate policy. Measures to reduce greenhouse gas emissions will be implemented in most sectors in Norway. A climate and energy fund will be established for the development of emission reduction technology. The CO 2 tax on emissions from Norway's offshore petroleum production will rise by Nok 200 per tonne, giving operating companies a stronger incentive to use electricity generated onshore. The Government will also focus on public transport, energy-efficient housing and forest-related measures to maintain and increase CO 2 uptake.(Author)

    As this issue of the newsletter is being published, the 50th General Conference of the IAEA is meeting in Vienna. Isotope Hydrology has been a part of the IAEA's activities almost from the beginning of the IAEA fifty years ago. After making substantial contributions to the scientific field, the isotope hydrology portion of the IAEA's work acquired the status of a programme and was renamed the programme on water resources. This reflected both the importance of water in sustainable development and the wider role of the IAEA in enabling countries to develop their human and institutional capacity for using isotope techniques. Since then, the programme of work in water resources has focused to a large part on identifying and removing obstacles to a wider use of isotopes in water resources management. In this issue of the Newsletter, a number of contributions discuss the application of isotopes in coastal zones, managing aquifer recharge, groundwater contamination

  13. IL-21 Receptor Expression in Human Tendinopathy

    2014-01-01

    Full Text Available The pathogenetic mechanisms underlying tendinopathy remain unclear, with much debate as to whether inflammation or degradation has the prominent role. Increasing evidence points toward an early inflammatory infiltrate and associated inflammatory cytokine production in human and animal models of tendon disease. The IL-21/IL-21R axis is a proinflammatory cytokine complex that has been associated with chronic inflammatory diseases including rheumatoid arthritis and inflammatory bowel disease. This project aimed to investigate the role and expression of the cytokine/receptor pair IL-21/IL-21R in human tendinopathy. We found significantly elevated expression of IL-21 receptor message and protein in human tendon samples but found no convincing evidence of the presence of IL-21 at message or protein level. The level of expression of IL-21R message/protein in human tenocytes was significantly upregulated by proinflammatory cytokines (TNFα/IL-1β in vitro. These findings demonstrate that IL-21R is present in early human tendinopathy mainly expressed by tenocytes and macrophages. Despite a lack of IL-21 expression, these data again suggest that early tendinopathy has an inflammatory/cytokine phenotype, which may provide novel translational targets in the treatment of tendinopathy.

    Full Text Available O experimento foi realizado para avaliar o desempenho e o teor de minerais na cama de frangos no período de 1 a 21 dias de idade, alimentados com rações contendo níveis reduzidos de proteína bruta (PB e fósforo disponível (Pd suplementadas com aminoácidos e fitase. Foram utilizados 1.500 pintos de corte machos de um dia de idade, da marca comercial Cobb, distribuídos em delineamento de blocos casualizados, em esquema fatorial 3 x 3 + 1, com três níveis de PB (15, 17 e 19%, três de Pd (0,25; 0,34 e 0,45% e uma ração controle formulada de acordo com os níveis nutricionais recomendados por pesquisadores brasileiros, totalizando dez tratamentos e seis repetições de 25 aves. Nas rações com 0,25 e 0,34% de Pd, adicionaram-se 500 FTU de fitase, reduzindo em 17% o teor de cálcio. O ganho de peso das aves que consumiram as rações com 17% de PB, 0,34 e 0,45 de Pd ou com 19% de PB e diferentes de níveis de Pd foi similar ao daquelas alimentadas com a ração controle. O consumo das aves que receberam as rações com 15 e 17% de PB e 0,25% de Pd + fitase foi menor que o daquelas que consumiram a ração controle. Não houve diferenças entre as rações para a conversão alimentar. Com exceção do nitrogênio, houve redução nos teores de minerais na cama quando as aves foram alimentadas com a ração contendo 17% de PB e 0,34% de Pd. Reduções para 17% nos teores de PB e para 0,34% nos teores de Pd das rações para frangos na fase inicial não prejudicam o desempenho das aves, desde que as rações sejam suplementadas com aminoácidos e fitase. Nesses níveis de PB e Pd, observou-se redução no impacto ambiental, como conseqüência da redução nos teores de P, Ca, Cu e Zn na cama.The trial was carried out to evaluate the performance and mineral levels in the litter of broilers from 1 to 21 days old, fed diets with low-crude protein (CP and low available phosphorus (AP supplemented with synthetic amino acids and phytase.

    Carter, D

    1996-01-01

    The Canada Center for Remote Sensing, in collaboration with the International Development Research Center, is developing an electronic atlas of Agenda 21, the Earth Summit action plan. This initiative promises to ease access for researchers and practitioners to implement the Agenda 21-action plan, which in its pilot study will focus on biological diversity. Known as the Biodiversity Volume of the Electronic Atlas of Agenda 21 (ELADA 21), this computer software technology will contain information and data on biodiversity, genetics, species, ecosystems, and ecosystem services. Specifically, it includes several country studies, documentation, as well as interactive scenarios linking biodiversity to socioeconomic issues. ELADA 21 will empower countries and agencies to report on and better manage biodiversity and related information. The atlas can be used to develop and test various scenarios and to exchange information within the South and with industrialized countries. At present, ELADA 21 has generated interest and becomes more available in the market. The challenge confronting the project team, however, is to find the atlas a permanent home, a country or agency willing to assume responsibility for maintaining, upgrading, and updating the software.

  7. Free-Spinning-Tunnel Investigation to Determine the Effect of Spin-Recovery Rockets and Thrust Simulation on the Recovery Characteristics of a 1/21-Scale Model of the Chance Vought F7U-3 Airplane, TED No. NACA AD 3103

    1955-01-01

    An investigation of a l/21-scale model of the Chance Vought F7U-3 airplane in the co&at-load- condition has been conducted in the Langley 20-foot free-spinning tunnel, The recovery characteristics of the model were determined by use of spin-recovery rockets for the erect and inverted spinning condition. The rockets were so placed as to provide either a yawing or rolling moment about the model center of gravity. Also included in the investigation were tests to determine the effect of simulated engine thrust on the recovery characteristics of the model. On the basis of model tests, recoveries from erect and inverted spins were satisfactory when a yawing moment of 22,200 foot-pounds (full scale) was provided against the spin by rockets attached to the wing tips; the anti-spin yawing moment was applied for approximately 9 seconds, (full scale). Satisfactory recoveries were obtained from erect spins when a rolling moment of 22,200 foot-pounds (full scale) was provided with the spin (rolls right wing down in right spin). Although the inverted spin was satisfactorily terminated when a rolling moment of equal magnitude was provided, a roll rocket was not considered to be an optimum spin-recovery device to effect recoveries from inverted spins for this airplane because of resulting gyrations during spin recovery. Simulation of engine thrust had no apparent effect on the spin recovery characteristics.

To simplify the use of all three Indexes we retained, as much as possible, the previous structure and key words (mutant varieties, other mutants mentioned, varieties treated, other varieties mentioned, mutagens used, breeding objectives, and country). However, it should be considered that Latin names of species, their taxonomic relationships and common names have been left as published in Mutation Breeding Newsletters (MBNLs), following author's classification. Synonym species names, as well as names of the same variety but with different spelling or with typing error are presented in brackets. It should be noted that over this period of time the transcription rules from other alphabets to English have been changed a few times, especially in relation to Chinese and Russian languages, which leads to duplications or misunderstandings in preparation of successive issues of MBNL. The Index will also be available through our web site http://www.iaea.org/programmes/nafa/d2/index.html (click on Publications/Newsletters). We hope that now, in the era of the renaissance of applications of mutation techniques, this Index will become a very useful tool for plant breeders, geneticists and molecular biologists searching for information on mutated lines, mutagens and applied doses.

    Bee K Tan

    Full Text Available OBJECTIVES: Circulating Fibroblast Growth Factor 21 (FGF21 levels are increased in insulin resistant states such as obesity, type 2 diabetes mellitus and gestational diabetes mellitus (GDM. In addition, GDM is associated with serious maternal and fetal complications. We sought to study human cerebrospinal fluid (CSF and corresponding circulating FGF21 levels in women with gestational diabetes mellitus (GDM and in age and BMI matched control subjects. We also assessed FGF21 secretion from GDM and control human placental explants. DESIGN: CSF and corresponding plasma FGF21 levels of 24 women were measured by ELISA [12 GDM (age: 26-47 years, BMI: 24.3-36.3 kg/m(2 and 12 controls (age: 22-40 years, BMI: 30.1-37.0 kg/m(2]. FGF21 levels in conditioned media were secretion from GDM and control human placental explants were also measured by ELISA. RESULTS: Glucose, HOMA-IR and circulating NEFA levels were significantly higher in women with GDM compared to control subjects. Plasma FGF21 levels were significantly higher in women with GDM compared to control subjects [234.3 (150.2-352.7 vs. 115.5 (60.5-188.7 pg/ml; P<0.05]. However, there was no significant difference in CSF FGF21 levels in women with GDM compared to control subjects. Interestingly, CSF/Plasma FGF21 ratio was significantly lower in women with GDM compared to control subjects [0.4 (0.3-0.6 vs. 0.8 (0.5-1.6; P<0.05]. FGF21 secretion into conditioned media was significantly lower in human placental explants from women with GDM compared to control subjects (P<0.05. CONCLUSIONS: The central actions of FGF21 in GDM subjects maybe pivotal in the pathogenesis of insulin resistance in GDM subjects. The significance of FGF21 produced by the placenta remains uncharted and maybe crucial in our understanding of the patho-physiology of GDM and its associated maternal and fetal complications. Future research should seek to elucidate these points.

    The nitrate (NO3-) transporter has been selected as an important gene maker in the process of environmental adoption in rice cultivars. In this work, we transferred another native OsNAR2.1 promoter with driving OsNAR2.1 gene into rice plants. The transgenic lines with exogenous pOsNAR2.1:OsNAR2.1 constructs showed enhanced OsNAR2.1 expression level, compared with wild type (WT), and 15 N influx in roots increased 21%-32% in response to 0.2 mm and 2.5 mm 15NO3- and 1.25 mm 15 NH 4 15 NO 3 . Under these three N conditions, the biomass of the pOsNAR2.1:OsNAR2.1 transgenic lines increased 143%, 129% and 51%, and total N content increased 161%, 242% and 69%, respectively, compared to WT. Furthermore in field experiments we found the grain yield, agricultural nitrogen use efficiency (ANUE), and dry matter transfer of pOsNAR2.1:OsNAR2.1 plants increased by about 21%, 22% and 21%, compared to WT. We also compared the phenotypes of pOsNAR2.1:OsNAR2.1 and pOsNAR2.1:OsNRT2.1 transgenic lines in the field, found that postanthesis N uptake differed significantly between them, and in comparison with the WT. Postanthesis N uptake (PANU) increased approximately 39% and 85%, in the pOsNAR2.1:OsNAR2.1 and pOsNAR2.1:OsNRT2.1 transgenic lines, respectively, possibly because OsNRT2.1 expression was less in the pOsNAR2.1:OsNAR2.1 lines than in the pOsNAR2.1:OsNRT2.1 lines during the late growth stage. These results show that rice NO 3 - uptake, yield and NUE were improved by increased OsNAR2.1 expression via its native promoter. © 2017 The Authors.

    2015-01-01

    NoSQL data storage systems have become very popular due to their scalability and ease of use. This paper examines the maturity of security measures for NoSQL databases, addressing their new query and access mechanisms. For example the emergence of new query formats makes the old SQL injection techniques irrelevant, but are NoSQL databases immune to injection in general? The answer is NO. Here we present a few techniques for attacking NoSQL databases such as injections and CSRF. We analyze the...

    Cancer, a major health problem, affects 12 million people worldwide every year. With surgery and chemo-radiation the long term survival rate for the majority of cancer patients is dismal. Thus novel treatments are urgently needed. Immunotherapy, the harnessing of the immune system to destroy cancer cells is an attractive option with potential for long term anti-tumor benefit. Cytokines are biological response modifiers that stimulate anti-tumor immune responses. In this review, we discuss the anti-tumor efficacy of the chemotactic cytokine CCL21 and its pre-clinical and clinical application in cancer.

    Full Text Available The motivation to carry out this study stemmed from the generalized perception that nowadays youth lacks the skills for the 21st century. Especially the high-level competences like critical thinking, problem solving and autonomy. Several tools can help to improve these competences (e.g. the SCRATCH programming language, but, as researchers and educators, we are mostly concerned with the skill to recognize problems. What if we do not find problems to solve? What if we do not even feel the need to find or solve problems? The problem is to recognize the problem; the next step is to equate the problem; finally we have to feel the need to solve it. No need? No invention. Recognizing a problem is probably the biggest problem of everyday life, because we are permanently faced with problems (many ill-defined problems, which we need to identify, equate and solve.

  1. [Trisomy 21 in visual art].

    Stahl, A; Tourame, P

    2013-12-01

    In 1866, J. Langdon Down published a paper on "an ethnic classification of idiots" and noted their facial resemblance with individuals of the Mongolian people. In 1959, J. Lejeune, M. Gautier, and R. Turpin demonstrated that the children with Down syndrome had an extra copy of chromosome 21. There is now a debate within the medical literature on the age of trisomy 21 as a disease affecting mankind. Since it was not described before 1866, some authors questioned whether this disease is an old or new condition in humans. Three methods of investigation are useful for demonstrating that trisomy 21 has been present in humans for a long time: the figuration of this condition in historical paintings, figurines, and pottery; its presence in old skeletal remains; and the origin of human chromosome 21 during primate phylogeny. Figurines strongly suggestive of trisomy 21 have been found in the Greco-Roman world, in many Central and South American pre-Columbian cultures, and in Khmer temples. In Europe, during the Renaissance, Italian and Flemish artists represented trisomy 21 in paintings of religious inspiration. Studies on the origin and pathology of chromosome 21 have shown that the ancestral human chromosome 21 arose 30-50 million years ago and that trisomy 21 has existed since time immemorial.

    Nitrogen oxides (NOx NO + NO2) are key actors in air quality and climate change. Tropospheric NO2 columns from the nadir-viewing satellite sensors have been widely used to understand sources and chemistry of NOx. We have implemented several improvements to the operational algorithm developed at NASA GSFC and retrieved tropospheric NO2 columns. We present tropospheric NO2 validation studies of the new OMI Standard Product version 2.1 using ground-based and in-situ aircraft measurements. We show how vertical profile of scattering weight and a-priori NO2 profile shapes, which are taken from chemistry-transport models, affect air mass factor (AMF) and therefore tropospheric NO2 retrievals. Users can take advantage of scattering weights information that is made available in the operational NO2 product. Improved tropospheric NO2 data retrieved using thoroughly evaluated high spatial resolution NO2 profiles are helpful to test models.

    Title: c=c(1+1=2) The light speed 1+1=2. So we count the number by step by step for one point. When we count the number by one point, we use the number written on the paper. This means this is not number, but the graph and line. The light speed is the truth in physics. I can prove it by number. 10%=0.1 As %=kg So 10kg=0.1 kg=1/10 x 1/10 kg=1/100 And 100%=1 So kg=100%/100 kg=% So 1kg=1%=1/100 E=mc^2 So cx kgx m^2/sec^2= 1kgx cx m^2/sec^2 cx 1/100x m^2/sec^2= 1/100x cx m^2/sec^2 So c/100=c/100 So c=c And c is the truth never changed. Title: By faith, no blackhole As to be, we glory to God and that is basic theology for christian. And I want to say that BE means just thinking. There is no clue of nature and no proposition to prove it. I just believe by feeling and emotion. I trust that it can be the physic really. There are only human beings and there is no idol that is different existence from human beings, that is true to be. So the nature we see is zero and we, human beings make the zero nature as from no start and no ending. No alpha and omega mean we are idol and that there is no blackhole. Blackhole means the block is existing in the nothing(as we are no alpha and no omega). So the block cannot be existence. So if there is blackhole, then there must be the wall to block me and never walk again. The big bang and evolution mean they are no alpha and no omega and existing by themselves. So they could be existence, but big bang and evolution are just logical fact to be. We need faith as God give us the direction into our spirit.

    DESIGN AND METHODS: We studied muscular FGF-21 expression and plasma FGF-21 after acute insulin stimulation in young healthy men during a hyperinsulinemic-euglycemic clamp. Furthermore, we investigated systemic levels and muscle FGF-21 expression in humans with or without insulin resistance and chronic...... elevated insulin. RESULTS: FGF-21 was barely detectable in young healthy men before insulin infusion. After 3 or 4 h of insulin infusion during a hyperinsulinemic-euglycemic clamp, muscular FGF-21 expression increased significantly. Plasma FGF-21 followed the same pattern. In individuals with chronic...... elevated insulin, muscular FGF-21 expression was associated with hyperinsulinemia in men but not in women. In plasma, hyperinsulinemia and fasting glucose were positively associated with plasma FGF-21 while plasma FGF-21 correlated negatively with HDL cholesterol. No associations between muscle and plasma...

  11. 21st Century Cell Culture for 21st Century Toxicology.

    Science.gov (United States)

    Pamies, David; Hartung, Thomas

    2017-01-17

    There is no good science in bad models. Cell culture is especially prone to artifacts. A number of novel cell culture technologies have become more broadly available in the 21st century, which allow overcoming limitations of traditional culture and are more physiologically relevant. These include the use of stem-cell derived human cells, cocultures of different cell types, scaffolds and extracellular matrices, perfusion platforms (such as microfluidics), 3D culture, organ-on-chip technologies, tissue architecture, and organ functionality. The physiological relevance of such models is further enhanced by the measurement of biomarkers (e.g., key events of pathways), organ specific functionality, and more comprehensive assessment cell responses by high-content methods. These approaches are still rarely combined to create microphysiological systems. The complexity of the combination of these technologies can generate results closer to the in vivo situation but increases the number of parameters to control, bringing some new challenges. In fact, we do not argue that all cell culture needs to be that sophisticated. The efforts taken are determined by the purpose of our experiments and tests. If only a very specific molecular target to cell response is of interest, a very simple model, which reflects this, might be much more suited to allow standardization and high-throughput. However, the less defined the end point of interest and cellular response are, the better we should approximate organ- or tissue-like culture conditions to make physiological responses more probable. Besides these technologic advances, important progress in the quality assurance and reporting on cell cultures as well as the validation of cellular test systems brings the utility of cell cultures to a new level. The advancement and broader implementation of Good Cell Culture Practice (GCCP) is key here. In toxicology, this is a major prerequisite for meaningful and reliable results, ultimately

    We report an unusual case of agnathia-holoprosencephaly associated with Down syndrome due to a 21/21 translocation. The patient presented prenatally at 21 wks gestation. A fetal ultrasound revealed multiple CNS anomalies including hydrocephalus, compressed cerebellum, absent septum pellucidum and possible cranial meningocele or encephalocele. High resolution ultrasound & fetal karyotype were recommended. The patient refused & elected to have a pregnancy termination. Chromosomal analysis performed on products of conception revealed a 46,XY,-21,+t(21q;21q) karyotype. Fluorescence in situ hybridization was performed and confirmed the 21/21 translocation chromosome. An autopsy revealed agnathia and multiple CNS anomalies including absence of the septum pellucidum, absence of the corpus callosum, arhinencephaly, an occiptal meningoencephalocele, dilation of the lateral ventricles, and extensive dysgenesis & heterotopias of the central cerebrum & mid-brain. Additional abnormalities included a persistent left superior vena cava, atrial & ventricular septal defects, irregular length of the fingers with absence of the middle phalanges of the right 2nd and 5th & left 5th digits and bilateral simian creases. Agnathia can be an isolated abnormality but often is associated with holoprosencephaly and/or situs inversus. The majority of familial case of agnathis-holoprosencephaly was caused by an inherited unbalanced translocation resulting in duplication of 6p and monosomy of 18p. Our patient had a translocation form of trisomy 21 but did not have a phenotype consistent with Down syndrome. Trisomy 21 has not been previously reported in other cases of agnathia-holoprosencephaly. Whether the chromosomal abnormality caused the phenotypic abnormalities or if it is a coincidental finding cannot be determined.

    Poverty, the increasing urbanisation of poverty and the environmental degradation are major problems facing the actual world. This is reflected in international conferences and agendas, such as Local Agenda 21. This agenda is responding to the current problems by promoting sustainable development through local action and by using participatory methods. Our major concern is to reflect on the impact of the Local Agenda 21 on the reduction of poverty in a Third World context.

    We introduce two operator commutators by using different-degree loop algebras of the Lie algebra A1, then under the framework of zero curvature equations we generate two (2+1)-dimensional integrable hierarchies, including the (2+1)-dimensional shallow water wave (SWW) hierarchy and the (2+1)-dimensional Kaup-Newell (KN) hierarchy. Through reduction of the (2+1)-dimensional hierarchies, we get a (2+1)-dimensional SWW equation and a (2+1)-dimensional KN equation. Furthermore, we obtain two Darboux transformations of the (2+1)-dimensional SWW equation. Similarly, the Darboux transformations of the (2+1)-dimensional KN equation could be deduced. Finally, with the help of the spatial spectral matrix of SWW hierarchy, we generate a (2+1) heat equation and a (2+1) nonlinear generalized SWW system containing inverse operators with respect to the variables x and y by using a reduction spectral problem from the self-dual Yang-Mills equations.

    Before there is a funded space mission, there must be a present need for the mission. Space science and exploration are expensive, and without a well-defined and justifiable need, no one is going to commit significant funding for any space endeavor. However, as discussed in Chapter 1, applications of space technology and many and broad, hence there are many ways to determine and establish a mission need. Robotic science missions are justified by their science return. To be selected for flight, questions like these must be addressed: What is the science question that needs answering, and will the proposed mission be the most cost-effective way to answer it? Why does answering the question require an expensive space flight, instead of some ground-based alternative? If the question can only be answered by flying in space, then why is this approach better than other potential approaches? How much will it cost? And is the technology required to answer the question in hand and ready to use? If not, then how much will it cost and how long will it take to mature the technology to a usable level? There are also many ways to justify human exploration missions, including science return, technology advancement, as well as intangible reasons, such as national pride. Nonetheless, many of the questions that need answering, are similar to those for robotic science missions: Where are the people going, why, and will the proposed mission be the most cost-effective way to get there? What is the safest method to achieve the goal? How much will it cost? And is the technology required to get there and keep the crew alive in hand and ready to use? If not, then how much will it cost and how long will it take to mature the technology to a usable level? Another reason for some groups sending spacecraft into space is for profit. Telecommunications, geospatial imaging, and tourism are examples of proven, market-driven space missions and applications. For this specific set of users, the

    To investigate the expression of p21 and p27 factors in gallbladder cancer (GBC), and to correlate their expression with clinicopathological parameters: age, gender, stage, invasion and grade. Thirty-two surgically resected specimens were collected between 1994-2001 from different health centers in north Jordan. Tissues belong to 25 females and 7 males were examined immunohistochemically. The study took place in the Pathology Department, Jordan University of Science and Technology, Jordan. Levels of p21 were found in 75% and p27 in 25%. Furthermore, p21 was expressed in 50% of the specimens which belong to patients with ages 64 years have p 21WAF1/CIP1 expression (p=0.001). The expression of p21 between advanced stages (stages III and IV) was 89.5% and early stages (stages I and II) was 53.8% (p=0.031). The p27 expression was markedly decreased in GBC cases (25%) and there were no significant correlation between p27KIP1 expression and all clinicopathological parameters including gender, World health Organization grades, stages and invasion, whereas expression of p21 was 75% and there was a significant correlation between p21 and clinicopathological parameters including gender, stages and invasion.

    The Norwegian Government intends to take a number of steps to reduce greenhouse gas emissions and promote technological advances. Some of the most important are: establishing a new climate and energy fund, raising the CO{sub 2} tax rate for the offshore industry, and improving public transport. The white paper keeps to the targets set out in the 2008 agreement on climate policy. Measures to reduce greenhouse gas emissions will be implemented in most sectors in Norway. A climate and energy fund will be established for the development of emission reduction technology. The CO{sub 2} tax on emissions from Norway's offshore petroleum production will rise by Nok 200 per tonne, giving operating companies a stronger incentive to use electricity generated onshore. The Government will also focus on public transport, energy-efficient housing and forest-related measures to maintain and increase CO{sub 2} uptake.(Author)

    The present report mainly explained the new concept of `long-term energy supply and demand prospects` for Japan`s energy policy. The most important point for the energy planning is the stable growth of economy. Having the trade problem, Japan needs a high growth rate of economy. In the latest revision, it is estimated to be annually 3% on average. In the global environment problem, Japan is to fix the CO2 emission per populational person at its level of 1990. The elastic modules of energy consumption came to be controlled to 0.3 with an excessive expectance of energy saving to satisfy the contradictory premise. As important political measures, the nuclear energy is most highly expected next to the energy saving. In Japan, its share will be 50% at the highest. As a conclusion, oil, natural gas and coal will be important energy resources as before. The environment tax and carbon tax are conceptually to control the consumption by heightening the oil price. The easing of regulation aims at lowering it to its worldwide level, which yields a contradictory debate.

    Interleukin-21 (IL-21) is a cytokine which plays a significant role in the pathogenesis and disease activity of rheumatoid arthritis (RA). Genetic polymorphisms in the IL-21 gene may alter the synthesis of IL-21. The aim of this study was to examine IL-21 and IL-21R polymorphisms in patients with RA. We examined 422 patients with RA and 338 healthy controls. Single nucleotide polymorphisms (SNPs) within the IL-21 (rs6822844 G>T, rs6840978 C>T, rs2221903 T>C) and IL-21R (rs2285452 G>A) genes were genotyped using TaqMan genotyping assays. There were no statistically significant differences in the distribution of studied genotypes and alleles between RA patients and the control group. To examine whether IL-21 polymorphisms affect disease activity in RA patients, we compared the distribution of IL-21 genotypes between patients with DAS28 ≤ 2.5 (patients with remission of disease symptoms) and patients with DAS28 > 2.5 (patients with active RA). Among patients with DAS28 > 2.5, increased prevalence of rs2221903 CT and CC genotypes was observed (OR = 1.54; 95% CI: 1.04-2.28; p = 0.035). The results of this study suggest that IL-21 and IL-21R gene polymorphisms are not risk loci for RA susceptibility, whereas the IL-21 rs2221903 polymorphism is associated with disease activity.

    In addition to many drastic changes, e.g. high aging population, globalization, and information renovation, Japan is also facing many structural problems such as government budget reform. This report enumerates the several problems using `Medium-Term Economic Forecasting System 1998,` which is composed of the macro econometric model, fiscal model, energy demand model, interindustry model and regional econometric model. Forecasting with this model, the average economic growth rate is predicted as 1.6%/year over the following decade. To avoid a serious demand shortage, an additional government expenditure of 40 to 50 trillion yen is necessary. Technological progress and investment for human capital are two policy measures that can help offset the supply constraints caused by a decrease in the labor force and savings rate decline. The industrial analysis outlook indicates that the production share of electrical machinery industry will expand, yet the information technology industry will be the leader in the Japanese economy so long as the information infrastructure is supported. Regionally, private investment in each region can help to offset the current expanding differences of regional productivities. As the difference in the utilization of public capital in each region contributes to the disparity of the public investment multiplier, this should be examined as a possible policy tool. From the industrial changes, we also see a change in the energy demand, as the growth rate of total energy demand. The outlook for the energy analysis shows that to restrain the carbon dioxide emissions at the 1990 level, technology innovation, changes in consumer behavior, and appropriate structural reform, for example in the energy tax structure are required.

  10. CCSVI and MS: no meaning, no fact.

    2013-03-01

    A condition called "chronic cerebrospinal venous insufficiency" (CCSVI) has been postulated to play a role in the pathogenesis of multiple sclerosis (MS). This hypothesis implies that a complex pattern of extracranial venous stenosis determines a venous reflux into the brain of MS patients, followed by increased intravenous pressure, blood-brain barrier breakdown and iron deposition into the brain parenchyma, thus triggering a local inflammatory response. In this review, we critically analyze the scientific basis of CCSVI, the current literature on the relationship between CCSVI and MS, as well as the ultrasound methodology that has been claimed to provide evidence of impaired cerebral venous drainage. We show that no piece of the CCSVI theory has a solid supportive scientific evidence. The CCSVI appears to be a rather alien condition and its existence should be definitely questioned. Finally, no proven (i.e., based on strict scientific methodology and on the rules of evidence-based medicine) therapeutic effect of the "liberation" procedure (unblocking the extracranial venous obstruction using angioplasty) has been shown up to date.

  12. Development of full sweet, umami, and bitter taste responsiveness requires Regulator of G protein Signaling-21 (RGS21).

    Science.gov (United States)

    Schroer, Adam B; Gross, Joshua D; Kaski, Shane W; Wix, Kim; Siderovski, David P; Vandenbeuch, Aurelie; Setola, Vincent

    2018-04-26

    The mammalian tastes of sweet, umami, and bitter are initiated by activation of G protein-coupled receptors (GPCRs) of the T1R and T2R families on taste receptor cells. GPCRs signal via nucleotide exchange and hydrolysis, the latter hastened by GTPase-accelerating proteins (GAPs) that include the Regulators of G protein Signaling (RGS) protein family. We previously reported that RGS21, uniquely expressed in Type II taste receptor cells, decreases the potency of bitter-stimulated T2R signaling in cultured cells, consistent with its in vitro GAP activity. However, the role of RGS21 in organismal responses to GPCR-mediated tastants was not established. Here, we characterized mice lacking the Rgs21 fifth exon. Eliminating Rgs21 expression had no effect on body mass accumulation (a measure of alimentation), fungiform papillae number and morphology, circumvallate papillae morphology, and taste bud number. Two-bottle preference tests, however, revealed that Rgs21-null mice have blunted aversion to quinine and denatonium, and blunted preference for monosodium glutamate, the sweeteners sucrose and SC45647, and (surprisingly) NaCl. Observed reductions in GPCR-mediated tastant responses upon Rgs21 loss are opposite to original expectations, given that loss of RGS21 -- a GPCR signaling negative regulator -- should lead to increased responsiveness to tastant-mediated GPCR signaling (all else being equal). Yet, reduced organismal tastant responses are consistent with observations of reduced chorda tympani nerve recordings in Rgs21-null mice. Reduced tastant-mediated responses and behaviors exhibited by adult mice lacking Rgs21 expression since birth have thus revealed an underappreciated requirement for a GPCR GAP to establish the full character of tastant signaling.

  17. Optimization of the deposition process of corrosion resistant Stellite 6 coatings produced by laser cladding; Optimizacion del proceso de aporte de recubrimientos anticorrosion de Stellite 6 producidos mediante plaqueado laser

    Laser cladding is one of the most efficient surface treatment technologies in the industry. It uses a laser heat source to deposit a thin layer of a desired material on a moving substrate, whose properties have to be improved, achieving a metallurgical bonding between them with low heat affected zone and low dilution, compared to other conventional technologies such as PTA, TIG welding or thermal Spraying. In this sense, it is remarkable that there are 3 main application fields for laser cladding technology: restoration of refurbishment of damaged parts, surface coating against corrosion or wear, and rapid proto typing. the present work described a study of the optimization of the laser cladding of Co based coatings (Diamalloy 4060NS) on medium carbon steel C45 (AISI 1945). After laser treatment, the surface of the substrate materials is improved in terms of resistance against corrosion; this confirmed in the analysis performed afterwards. it is also shown that the corrosion barrier properties have direct correlation with the laser cladding variables.

    2012-08-01

    Imaging the Universe during the first hundreds of millions of years remains one of the exciting challenges facing modern cosmology. Observations of the redshifted 21 cm line of atomic hydrogen offer the potential of opening a new window into this epoch. This will transform our understanding of the formation of the first stars and galaxies and of the thermal history of the Universe. A new generation of radio telescopes is being constructed for this purpose with the first results starting to trickle in. In this review, we detail the physics that governs the 21 cm signal and describe what might be learnt from upcoming observations. We also generalize our discussion to intensity mapping of other atomic and molecular lines.

  3. No sliding in time

    International Nuclear Information System (INIS)

    Shtengel, Kirill; Nayak, Chetan; Bishara, Waheb; Chamon, Claudio

    2005-01-01

    In this letter, we analyse the following apparent paradox: as has been recently proved by Hastings (2004 Phys. Rev. 69 104431), under a general set of conditions, if a local Hamiltonian has a spectral gap above its (unique) ground state (GS), all connected equal-time correlation functions of local operators decay exponentially with distance. On the other hand, statistical mechanics provides us with examples of 3D models displaying so-called sliding phases (O'Hern et al 1999 Phys. Rev. Lett. 83 2745) which are characterized by the algebraic decay of correlations within 2D layers and exponential decay in the third direction. Interpreting this third direction as time would imply a gap in the corresponding (2+1)D quantum Hamiltonian which would seemingly contradict Hastings' theorem. The resolution of this paradox lies in the non-locality of such a quantum Hamiltonian. (letter to the editor)

  7. LRAD surface monitoring results at TA-21

    International Nuclear Information System (INIS)

    Bounds, J.A.

    1995-01-01

    In August/September 1994, NIS-6 personnel used LRAD soil surface monitor technology to characterize the extent of alpha contamination on the surface of a parking lot adjacent to TA-21, LANL, known as Material Disposal Area B. This report documents that monitoring. Based on this survey, there is no reason for concern about significant contamination in the parking area as a whole, although unexpected small hot spots could exist between the grid points where monitoring was performed. However, the grouping of high readings on the east side of the parking area does point to possible contamination at the level of 100 dpm/100 cm 2 or less (above background). Further monitoring or remediation of this area seems appropriate. In addition, because this was an alpha survey, one cannot rule out contamination under the asphalt or possibly between layers if it was paved more than once

    After four years of hard work, the COP21 has culminated in a climate agreement that was accepted by 195 countries. This agreement is the first to involve all world economies in the fight against climate change. Beyond the pledges made by the governments, the COP21 also aimed to highlight solutions that are backed by the private sector. A testimony to companies' determination to become a part of the movement, several initiatives were launched in a wide range of sectors over the course of the two conference weeks. Responding to these transformations, the financial sector also made several announcements, promising that it would divest from the most polluting energies, increase investments in clean technologies, stimulate financial innovation (green bonds, LDN) and measure carbon footprints. Investors have understood once and for all that they must adapt their investment strategies if they want to face up to the challenges of the current transition to a low carbon economy

    Full Text Available The article proposes action research as a legitimate way to develop and empower teachers to be active knowers and critical agents who are capable of undertaking innovative action to transform their practices and circumstances as educators. It begins by considering the development and empowerment of teachers as intentional processes that allow teachers not only to question and resist means of regulation and control, but also to take command of their own lives in a way that enables them to develop their professional skills. It goes on to show how teachers can construct a personal and contextual theory of education or pedagogical know-how by systematically researching their teaching practices and classroom situations. Finally, it looks at what action research is, explains the different types and stages of action research, shows how it has been used in Colombia and proposes possible research problems and the types of empowerment that can result from them. The article ends by stating that teachers should resort to action research not only to gain and wield power, but also to make way for self-development and professional growth.Se busca proponer la investigación, la investigación acción en concreto, como unaforma legítima para desarrollary empoderar a los profesores para que, como conocedores activos y agentes críticos, puedan iniciar acciones innovadoras para transformar sus prácticas y realidades educativas, lo que les permitirá construir su propio saber pedagógico.

    Full Text Available Hymenaea stigonocarpa, known as Jatoba-do-cerrado, belongs to the family Fabaceae (Leguminosae and is included in the category "near threatened with extinction." It occurs in cerrado and cerradão areas, and its seeds have physical dormancy. Because of this characteristic, the aim of this study was to evaluate different pre-germination treatments and control in H. stigonocarpa seeds, namely: immersion in fire, sulfuric acid, hydrochloric acid, acetone, ether and hot water (100°C, and mechanical scarification of the seed coat by roughing with sandpaper or cutting with nail clippers and washing in running water for 2 hours. The parameters analyzed were percentage of germination, germination speed index (GSI and the percentage of hard and firm seeds and dead seeds. The final results were: a germination: boiling water and sulfuric acid were superior to the control; b GSI: boiling water, sulfuric acid, fire and sandpaper were superior to the control and c percentage of dead seeds was not statistically different between the different treatments and control. In conclusion, boiling water and sulfuric acid, were the best treatments, with regard to the parameters examined.

    2009-12-01

    The unusual methylene aziridine 6-tert-butyl-3-oxa-2-thia-1-azabicyclo[5.1.0]oct-6-ene 2,2-dioxide, C(9)H(15)NO(3)S, was found to crystallize with two molecules in the asymmetric unit. The structure was solved in both the approximately orthogonal and the oblique settings of space group No. 14, viz. P2(1)/n and P2(1)/c, respectively. A comparison of these results clearly displayed an increase in the correlation between coordinates in the ac plane for the oblique cell. The increase in the corresponding covariances makes a significant contribution to the standard uncertainties of derived parameters, e.g. bond lengths. Since there is yet no CIF definition for the full variance-covariance matrix, there are clear advantages to reporting the structure in the nonstandard space-group setting.

  17. NO REFLOW PHENOMENON

    Directory of Open Access Journals (Sweden)

    2010-11-01

    Full Text Available Definition No reflow is a phenomenon in which myocardial ischemia and reduced antegrade flow occur despite the absence of proximal stenosis, spasm, dissection, or embolic cut off of major distal branches.1 In another word no reflow phenomenon means failure of restoration of myocardial flow despite removal of epicardial coronary obstruction.2 The incidence is 2% with plain balloon angioplasty (PTCA, 7% in patients undergoing rotational atherectomy, 12% for primary percutaneous coronary intervention (PCI, and much higher at 42% for PCI of degenerated Saphenous Vein Graft (SVG.3 No reflow is a strong predictor of mortality after PCI. The mortality of patients who developed no reflow has been estimated to be 8% Predictors of no reflow include a higher plaque burden, thrombus, lipid pools by intra vascular ultra sonography (IVUS, higher lesion elastic membrane cross sectional area, preinfarction angina and thrombolysis in myocardial infarction (TIMI flow grade 0 on the initial coronary angiogram. Mechanism The cause is mainly embolization of atheromatous material (gruel. Particles are composed of cholesterol clefts, lipid rich macrophages, fragments of fibrous cap, necrotic lesion core and fibrin. This is aggravated by microembolization of platelet-rich thrombi that release vasoactive agents (e.g., serotonin and thromboxane A2, leading to intense arteriolar vasopasm in the distal vasculature. In the animal laboratory, experimental no reflow has been shown to be due to the plugging of capillaries by red blood cells and neutrophils, myocyte contracture and local intracellular and interstitial edema.4,5      A loss of capillary autoregulation and severe microvascular dysfunction are the ultimate physiologic consequences of these microscopic anatomic alterations. Debris of varying sizes of particulate has variable effects on microcirculatory plugging. The effect of particle size on microvascular dysfunction has been mostly investigated during

    2017-10-01

    Full Text Available É sabido como o escritor italiano Giorgio Manganelli (1922-1990 amava escrever para seus livros orelhas e contracapas que, de alguma forma, dialogavam e integravam o próprio texto. Já em dois dos seus três livros traduzidos no Brasil – Hilarotragoedia (Imago, 1993 e Centúria (Iluminuras, 1995 –, encontram- se prefácios e introduções, sendo reposicionados ou parcialmente omitidos os peritextos, de acordo com a definição de Genette, originais. Este artigo, portanto, pretende analisar a diferente articulação dos paratextos nas edições traduzidas, a fim de refletir sobre as estratégias pensadas para a recepção no Brasil de um autor, sem dúvida, de difícil acesso.

  1. No-Scale Inflation

    CERN Document Server

    Ellis, John; Nanopoulos, Dimitri V.; Olive, Keith A.

    2016-01-01

    Supersymmetry is the most natural framework for physics above the TeV scale, and the corresponding framework for early-Universe cosmology, including inflation, is supergravity. No-scale supergravity emerges from generic string compactifications and yields a non-negative potential, and is therefore a plausible framework for constructing models of inflation. No-scale inflation yields naturally predictions similar to those of the Starobinsky model based on $R + R^2$ gravity, with a tilted spectrum of scalar perturbations: $n_s \\sim 0.96$, and small values of the tensor-to-scalar perturbation ratio $r < 0.1$, as favoured by Planck and other data on the cosmic microwave background (CMB). Detailed measurements of the CMB may provide insights into the embedding of inflation within string theory as well as its links to collider physics.

No-scale supergravity emerges from generic string compactifications and yields a non-negative potential, and is therefore a plausible framework for constructing models of inflation. No-scale inflation yields naturally predictions similar to those of the Starobinsky model based on R+{R}2 gravity, with a tilted spectrum of scalar perturbations: {n}s∼ 0.96, and small values of the tensor-to-scalar perturbation ratio r\\lt 0.1, as favoured by Planck and other data on the cosmic microwave background (CMB).

  3. No slip gravity

    Science.gov (United States)

    Linder, Eric V.

    2018-03-01

    A subclass of the Horndeski modified gravity theory we call No Slip Gravity has particularly interesting properties: 1) a speed of gravitational wave propagation equal to the speed of light, 2) equality between the effective gravitational coupling strengths to matter and light, Gmatter and Glight, hence no slip between the metric potentials, yet difference from Newton's constant, and 3) suppressed growth to give better agreement with galaxy clustering observations. We explore the characteristics and implications of this theory, and project observational constraints. We also give a simple expression for the ratio of the gravitational wave standard siren distance to the photon standard candle distance, in this theory and others, and enable a direct comparison of modified gravity in structure growth and in gravitational waves, an important crosscheck.

  4. Expression of p53 and p21 in primary glioblastomas

    Gross, M.W.; Nashwan, K.; Engenhart-Cabillic, R.; Kraus, A.; Mennel, H.D.; Schlegel, J.

    2005-01-01

    Background and purpose: primary glioblastomas (GBMs) are highly radioresistant, and in contrast to secondary GBMs, they bear wild-type (wt) p53 protein, which is stabilized in a proportion of these tumors. Therefore, it was investigated in vivo whether p53 expression has prognostic value in patients undergoing radiochemotherapy. Additionally, the authors tried to identify, in vitro, subgroups of primary GBM with different susceptibilities to irradiation, on the basis of their p53 and p21 responses to ionizing radiation. Material and methods: tumor tissue samples from 31 patients suffering from primary GBM undergoing a combined radiochemotherapy with topotecan were investigated. The percentage of cells expressing p53 protein was determined immunohistochemically. Additionally, primary cultures from eleven primary GBMs were established and investigated. p53 and p21 expressions were evaluated before irradiation with 10 Gy and at 2 and 8 h after irradiation. p53 protein expression was measured by western analysis and p21 mRNA expression by reverse transcription-polymerase chain reaction (RT-PCR). Results: the percentage of p53-positive cells within the tumor specimens obtained from the 31 patients ranged from 0% to 28%, the median value being 4.3%. No significant correlation with disease-free survival or overall survival was found. In vitro, p53 protein was detected in seven of eleven cultures from primary GBM. After irradiation a decrease in p53 protein expression was seen in six of the seven p53-positive cultures. Half of the cultures (two of four) without basal p53 expression showed an increase in p53 expression after irradiation. Basal overexpression of p21 was detected in six of the eleven cultures; in four out of six irradiation led to a decrease in p21 expression. In all cell lines (five of eleven) initially showing absent p21 expression, irradiation induced p21 expression. Despite these responses, G1 arrest was not detectable in any of the GBM cultures
