    International Nuclear Information System (INIS)

    A model diet for an Aboriginal adult living entirely on bush foods collected from the Alligator Rivers Region of the Northern Territory has been established. Results of investigations of the specific activities of thorium-230, radium-226, lead-210 and polonium-210 in 123 samples of bush foods collected by Ranger Uranium Mines Pty Ltd during pre-production and production periods are presented. For all the investigated bush food items, excluding freshwater mussels (Velesunio angasi), no systematic differences were found between the specific activities of the radionuclides monitored in food items sampled during preproduction and production periods. Preliminary estimates of annual effective dose equivalent (DE) rates for stochastic effects on an adult living entirely on the model bush diet are presented. Of the four radionuclides monitored the major contributor to the effective DE rates appears to be lead-210 followed by radium-226. Among the selected nine components of the diet the major contributor to the effective DE rates appear to be mussels, water lilies and fish

    Samples of Jamaican plants used as bush teas were collected from households in high soil-cadmium (Cd) areas of central Jamaica and analysed by graphite furnace atomic absorption spectrophotometry for total cadmium and for cadmium extractable with a hot water brew as prepared for human consumption to determine their contribution to dietary cadmium exposure. The concentrations ranged from < 0.03 to 6.85 µg/g for total Cd, between 1 and 15% of which was extracted with a hot water brew. One cup (200 ml) of the teas examined was found to contain < 0.04-1.18 µg of Cd and would contribute 0.1-0.3 µg of Cd to a person's dietary intake. This is significantly below the provisional tolerable weekly intake (PTWI) of 7 µg Cd/kg body weight established by the World Health Organization (WHO). While this suggests that bush tea consumption does not contribute significantly to the PTWI, some of the teas examined exceed the WHO recommendation of less than 0.3 mg/kg Cd for medicinal plants.

  9. Vannevar Bush: Fifty Years Later

    Lagowski, J. J.

    1995-12-01

    It is ironic that the 50th anniversary year of Vannevar Bush's Report to President Truman entitled "Science the Endless Frontier", which put into motion the eminently successful current system of education of scientists in this country occurs at a time when serious questions are being asked about the usefulness of that very system. Bush viewed his proposal to establish a national research foundation (later to be called the National Science Foundation) as a "social compact." Judgment of scientific merit would be delegated to expert peers in return for scientific progress, which would ultimately benefit the nation in terms of scientific needs--military security, economic productivity, and enhanced quality of life. Bush wanted the funding of basic research intertwined with training, and preferred to use universities for this purpose rather than industrial or national labs. Bush viewed college and university scientists as teachers and investigators. He believed university-based research would uniquely encourage and engage the next generation of scientists as no other institutional arrangement could. Bush did not trust industry's commitment to basic research, an instinct that proved prophetic. The academic reserve of scientists (PhD's in training and postdoctoral students) that existed before World War II, and upon which the United States could draw for its needs, which were primarily associated with defense efforts, was probably one of the defining factors in Bush's suggested strategy. Currently, that reserve of talent has gotten so large that it is the obvious throttle in the pipeline slowing the continued development of the university research enterprise. Since 1977, the rate at which we have trained new scientists exceeds an average of 4% annually. Since 1987, the "science work force"--PhD's--has grown at three times the rate of the general labor supply. Temporary positions for postdoctoral scientists have grown even faster (over 5% per year since 1989). To compound

The ITER radiation environment and the fact that the bushing forms part of the tritium barrier demand a component of great reliability and safety. An R and D task has been launched for the fabrication of a prototype bushing based on the SINgle GAP, SINGle APerture (SINGAP) 1 MeV accelerator being developed in the EU. We present the design of this prototype, which is to be tested at Cadarache, and compare it with the SINGAP bushing proposed for the ITER injectors

    Six men suffering from acute dermatitis had positive patch tests to Larrea (creosote bush). The lesions preferentially involved sun-exposed sites, simulating a photodermatitis, but also were on the legs and scrotum. Our findings were more consistent with contact allergy than with a primary irritant or a phototoxic response. The patch tests were also positive to Zuccagnia punctata. In two cases the exposure to the creosote bush occurred as a result of casual occupations, in two because of household remedies (moist compresses and baths), and in the other two as a result of burning the bush and resorting to household remedies. Attention should be drawn to this contact dermatitis because the creosote bush grows abundantly all over the American continent. PMID:3950120

    Full Text Available Bearings are among the most important components in the vast majority of machines. Bush is an independent plain bearing that is inserted into a housing to provide a bearing surface for rotary applications. Bushes are fitted either by pressing for less interference or by heating the frame or cooling the bushes using dry ice or liquid nitrogen. In the present case, due to uneven cooling using liquid nitrogen or other problems, bush is not fitting easily in some of the pump frames. So there is a need of a bush pressing machine. A ‘C’ frame type hydraulic bush pressing machine is designed in this work.

    The invention relates to an electrical bushing serving to make a connection at ambient temperature to a superconductor element situated in an enclosure at cryogenic temperature. The electrical bushing passes successively through an enclosure at intermediate temperature between ambient temperature and cryogenic temperature, and an enclosure at ambient temperature, and it comprises a central electrical conductor surrounded by an electrically insulating sheath. According to the invention, an electrically conductive screen connected to ground potential surrounds the insulating sheath over a section that extends from the end of the bushing that is in contact with the enclosure at cryogenic temperature at least as far as the junction between the enclosure at intermediate temperature and the enclosure at ambient temperature. The invention is more particularly applicable to making a connection to a superconductor cable.

    In the coming four years, the Middle East will continue to be the strategic focus of the United States. It can be seen in an analysis of the recent years's ituation that the Bush administration rather chose a war in the Middle East to achieve its strategic goals than used non-military measures to do the same thing. In the future the Bush administration might find it difficult to draw back from its policy on the Middle East, which will mean more losses than gains. This will probably continue to cause damage to both the soft and hard power of the U.S., and result in a downward trend of the U.S. power for a certain period of time.

    Savanna ecosystems are subject to desertification and bush encroachment, which reduce the carrying capacity for wildlife and livestock. Bush thinning is a management approach that can, at least temporarily, restore grasslands and raise the grazing value of the land. In this study we examined the soil microbial communities under bush and grass in Namibia. We analyzed the soil through a chronosequence where bush was thinned at 9, 5, or 3 years before sampling. Soil microbial biomass, the biomass of specific taxonomic groups, and overall microbial community structure was determined by phospholipid fatty acid analysis, while the community structure of Bacteria, Archaea, and fungi was determined by multiplex terminal restriction fragment length polymorphism analysis. Soil under bush had higher pH, C, N, and microbial biomass than under grass, and the microbial community structure was also altered under bush compared to grass. A major disturbance to the ecosystem, bush thinning, resulted in an altered microbial community structure compared to control plots, but the magnitude of this perturbation gradually declined with time. Community structure was primarily driven by pH, C, and N, while vegetation type, bush thinning, and time since bush thinning were of secondary importance.

    Full Text Available Polyetheretherketone (PEEK composites have been extensively studied because of the excellent tribological behavior among plastics. However, laboratory specimens and tests are generally discussed, whereas application studies on industrial components are infrequent. In this paper, an injection molded bush made of tribological PEEK was analyzed to correlate wear behavior and molded material structure. Bushes were tested under unlubricated sliding conditions by means of a short wear test. Surface analysis, differential scanning calorimetry (DSC and optical microscopy were used to evaluate the distribution of the different composite fillers (polytetrafluoroethylene, PTFE, graphite particles and carbon microfibers and their effect on the final bush behavior. A significant lack of homogeneity was observed in the molded bush and black bands appeared on the shaft surface after testing due to the sliding. The bush geometry and the injection molding process should be optimized to allow the best tribological behavior of the molded material under working conditions.

One of the critical components to be developed for high voltage superconducting devices, including superconducting transformers, cables, and fault current limiters, is a high voltage bushing, to supply high current to devices without insulating difficulties, that is designed for cryogenic environments. Unfortunately, suitable bushings for HTS equipment were not fully developed for some cryogenic insulation issues. Such high voltage bushings would need to provide electrical insulation capabilities from room temperature to cryogenic temperatures. In this paper, design factors of cryogenic bushings were discussed and test results of specimen were introduced in detail. First, the dielectric strength of three kinds of metals has been measured with uniform and non-uniform electrodes by withstand voltage of impulse and AC breakdown test in LN2. Second, puncture breakdown voltage of glass fiber reinforced plastics (GFRPs) plates has been analyzed with non-uniform electrodes. Finally, creepage discharge voltages were measured according to the configuration of non-uniform and uniform electrode on the FRP plate. From the test results, we obtained the basic design factors of extra high voltage condenser bushing, which could be used in cryogenic environment

  19. Hybrid neural network bushing model for vehicle dynamics simulation

    International Nuclear Information System (INIS)

    Although the linear model was widely used for the bushing model in vehicle suspension systems, it could not express the nonlinear characteristics of bushing in terms of the amplitude and the frequency. An artificial neural network model was suggested to consider the hysteretic responses of bushings. This model, however, often diverges due to the uncertainties of the neural network under the unexpected excitation inputs. In this paper, a hybrid neural network bushing model combining linear and neural network is suggested. A linear model was employed to represent linear stiffness and damping effects, and the artificial neural network algorithm was adopted to take into account the hysteretic responses. A rubber test was performed to capture bushing characteristics, where sine excitation with different frequencies and amplitudes is applied. Random test results were used to update the weighting factors of the neural network model. It is proven that the proposed model has more robust characteristics than a simple neural network model under step excitation input. A full car simulation was carried out to verify the proposed bushing models. It was shown that the hybrid model results are almost identical to the linear model under several maneuvers

    The Walker Bush dynasty has marked the last American century, promoting "corporate democracy" as a means to expand its wealth. As 43rd President of the United States, George Walker Bush's biography illustrates how the members of our powerful elite sacrifice the inner self of their own children for the sake of political success. In his case, the childrearing violence and emotional neglect he experienced created the psychological basis for his later re-enactments as commander-in-chief in the wake of 9/11. From that standpoint, his intergenerational legacy of trauma bears strong affinities with that of the nation as a whole. This paper examines George W. Bush's paternal inheritance, the problem of maternal abuse and its subsequent psychic wounds, as well as the impact of an unresolved grief after the loss of his younger sister, Robin. Restaging childhood traumas as a vengeful young adult at Yale, before getting involved in dirty politics, Bush supported unlawful hazing practices. Then, as Governor of Texas he promoted the death penalty and a zero-tolerance approach to juvenile offenders. Controversial decisions of the Bush administration regarding the Enhanced Interrogation Program, the Guantanamo Bay detention camp and many others are further scrutinized as collective re-enactments of abuse deeply engrained in American society.

In the last four years, they have criticized Bush and his administration for pushing changes to clean air law, forestry policy and endangered species laws. The administration has also come under fire for proposals to drill for oil in sensitive lands. These groups have found some potent allies in Congress, including some moderate Republicans, and in the states. Supporters of Bush environmental initiatives, including most Republican congressional leaders, industry groups and conservative organizations, have called his policy balanced and say that he brings a ''common sense'' approach to industry regulation. These two sides have found little in common in the last four years, and have compromised on almost nothing. As a result, the environment, once a bi-partisan issue, has become more and more a polarizing one. (author)

  3. High voltage bushing having weathershed and surrounding stress relief collar

    Science.gov (United States)

    Cookson, Alan H.

    1981-01-01

    A high voltage electric bushing comprises a hollow elongated dielectric weathershed which encloses a high voltage conductor. A collar formed of high voltage dielectric material is positioned over the weathershed and is bonded thereto by an interface material which precludes moisture-like contaminants from entering between the bonded portions. The collar is substantially thicker than the adjacent weathershed which it surrounds, providing relief of the electric stresses which would otherwise appear on the outer surface of the weathershed. The collar may include a conductive ring or capacitive foil to further relieve electric stresses experienced by the bushing.

Sous l’Administration Bush, et après une année de récession consécutive à l’éclatement de la « bulle internet », l’économie américaine a connu six années d’expansion. Cette expansion a été plus forte que dans les autres économies du G7, grâce notamment à une croissance plus élevée de la productivité et à une politique monétaire accommodante. Elle s’est néanmoins accompagnée d’un certain nombre de déséquilibres qui pesaient sur la situation dans les derniers mois de la présidence Bush.This article surveys the performance of the US economy over the eight years of the Bush Presidency. Under the Bush Administration and after a year of recession following the bursting of the internet bubble, the American economy enjoyed six years of expansion. This expansion was stronger than in the other G7 economies, thanks in particular to higher productivity growth and a very supportive monetary policy. However, it was the source of several imbalances which weighed on the situation as the Bush Presidency was drawing to a close.

    2016-01-01

    Full Text Available Rubber bushings used in the vehicle or aerospace can reduce the noise and vibration and absorb the shocks. The heat accumulation in the rubber components is attributed to the nonlinear mechanical behavior of rubber and leads to degeneration of mechanical properties. The viscoelastic damping is treated as the major mechanism of dissipation energy, which is heat source of temperature rising in bushing. A finite element method is expanded from elastic structure to viscoelastic structure and computes the dissipation energy distribution in the rubber core. Based on that heat source, the temperature distribution of rubber bushing under radial harmonic excitation has been calculated using finite volume method. The frequency and amplitude effect on dissipation energy and temperature distribution are described. The radial dynamic testing is carried out and the temperature is recorded using thermal imager to evaluate the simulation. As complement, the dynamic torsional testing is also carried out explore the possible failure zone of rubber bushing under different types of loading.

    Full Text Available The article is focused at the most important elements of the US foreign policy towards the Middle East during the administration of George W. Bush (2001 – 2009. The text has two parts. The first part shows three important influences on creation and formulation of the US foreign policy towards the region. At the first place it was an effort to preserve unipolar character of the international system, hegemonic possition of the USA and its dominance in all regions. The second source was specific decision-making process set up by president Bush and the third source of the Bush strategy was a partial transformation of the US longtime policy towards the Middle East. The second part of the article discuss results of the Bush doctrine in the region. The text is focused at five most important consequences of the US foreign policy, which are the fight against proliferation of weapons of mass destruction, the pursuit of the democratization throughout the region, the Israel-Palestinian conflict, regional “cold war” between Iran and Saudi Arabia and finally the struggle to stabilize the post-conflict Iraq.

  14. Identification of a novel ga-related bush mutant in pumpkin (cucurbita moschata duchesne)

    International Nuclear Information System (INIS)

    Pumpkin (Cucurbita moschata Duchesne) bush mutant plants were characterized by short stems. The sensitivity of pumpkin bush mutant plants to exogenous hormones was identified in this study. Results revealed that internode elongation of bush mutant plants could respond to gibberellins (GA4+7 and GA3), but not to indole acetic acid (IAA) and brassinosteroids (BR); by contrast, the mutant phenotype of bush mutant plants could not be fully rescued by GA4+7 and GA3. The internode of bush mutant plants yielded a lower KS expression level than that of vine plants. Therefore, pumpkin bush mutant plants were designated as GA-related mutant plants eliciting a partial response to GAs; the action of IAA and BR might not be involved in the internode growth of pumpkin bush mutant plants, specifically Cucurbita moschata Duch.

    Kim, Woo-Jin; Choi, Jae-Hyeong; Kim, Sang-Hyun

    2012-12-01

    For the operation of high temperature superconducting (HTS) power equipments, it is necessary to develop insulating materials and high voltage (HV) insulation technology at cryogenic temperature of bushing. Liquid nitrogen (LN2) is an attractive dielectric liquid. Also, the polymer insulating materials are expected to be used as solid materials such as glass fiber reinforced plastic (GFRP), polytetra-fluoroethylene (PTFE, Teflon), Silicon (Si) rubber, aromatic polyamide (Nomex), EPDM/Silicon alloy compound (EPDM/Si). In this paper, the surface flashover characteristics of various insulating materials in LN2 are studied. These results are studied at both AC and impulse voltage under a non-uniform field. The use of GFRP and Teflon as insulation body for HTS bushing should be much desirable. Especially, GFRP is excellent material not only surface flashover characteristics but also mechanical characteristics at cryogenic temperature. The surface flashover is most serious problem for the shed design in LN2 and operation of superconducting equipments.

  16. Beyond Bush: Environmental politics and prospects for US climate policy

    International Nuclear Information System (INIS)

    The United States was a pioneer in domestic environmental lawmaking, and it was a leader in international environmental cooperation in the final decades of the last century. During the current decade, however, it has moved away from cooperating with other states in finding new ways to protect the global environment. While its early efforts to address climate change were no worse, and often better than, other developed countries, it has fallen far behind as a number of European states and the European Union have started to implement robust policies to reduce their greenhouse gas emissions. This chapter recounts this evolution in US policy from environmental leader to environmental laggard. It summarizes the US climate change-related policies and diplomacy, recounting significant events during the presidential administrations of George HW Bush, Bill Clinton and George W Bush. It then extends this summary of events to assess the prospects for US climate policy in the near future

  17. Dynamic Spring Model of Rubber Bush Based on Linear Viscoelasticity

    Science.gov (United States)

    Fujikawa, Masaki; Sato, Masami; Kobayashi, Takaya

    A set of simplified formulae is proposed for estimating the dynamic spring constants of rubber bushes used in suspension systems. These formulae are structured by extending a set of elastic solutions[Editor2] proposed before to calculate the dynamic spring constants according to the associated law (pseudo-elasticity) of the linear viscoelasticity theory. A unique feature of this method is that it helps in the easy and quick evaluation of the dynamic behavior of rubber bushes for all the six degrees of freedom (axial loading, loading normal to an axis in two directions, wrench in two directions, and torsion[Editor3]) with no direct involvement of the FEM. In order to validate this method of calculation, the results obtained for all the degrees of freedom are compared with those obtained using the FEM. It is verified that this approach is capable of qualitatively reproducing the results obtained by using the FEM analysis.

    Full Text Available Creosote bush and tar bush are 2 xerophilic shrubs considered as potential animal feed after their fungal fermentation to reduce the tannins content. Kinetics of biodegradation of tannins during the fermentation of both plants by 2 strains of Aspergillus niger (GH1 and PSH were evaluated under solid state culture conditions. The in vitro digestibility and the presence of mycotoxins were also analyzed in the fermented plants. The growth of fungal strain was directly associated to biodegradation of tannins (hydrolysable and condensed tannins in both plants. A. niger GH1 degraded more than 94% of total tannins of creosote bush while, A. niger PSH degraded already of 77% of total tannins of tar bush. Results of digestibility of fermented materials were 9.72% for creosote bush and 13.98% for tar bush, respectively. Aflatoxins present in creosote bush were B1 (692 ppt, B2 (< 160 ppt and G1 (< 160 ppt and for tar bush B1 (182 ppt, B2 (< 160 ppt and G1 (< 160 ppt. These results showed that animal health risk by the consumption of these kinds of fermented products is very low because are according with the official norms.

    Full Text Available In a number of GIS installations, the connection to the transformer is given through either SF6 / air bushing or SF6 / oil bushing. The VFTO generated internal to GIS may propagate to the transformer winding through the above capacitive graded bushing (generally 245 KV and above. The voltage distribution under very fast transients may be highly non-linear due to having frequency components in the range of 100 MHz and above. Further, continuous application of these oscillating, aperiodic over voltages to the capacitively graded bushing may cause discharges inside the bushing, which may progressively degrade its insulation strength. The voltagedistribution across various layers of capacitively graded bushing has been estimated by representing the layers as an equivalent multi-stage Π sections with Pspice

All the interviewed households that own trees of species were found to preserve kernels in periods of abundance, excluding Elig-Nkouma (87.5%. Eighty nine and 85% did so in periods of scarcity for I. wombolu and I. gabonensis respectively. Seventeen and twenty-nine kernel preservation practices were recorded for I. wombolu and I. gabonensis respectively. Most were based on continuous heating of the kernels or kernel by-products (cakes. The most commonly involved keeping the sun-dried kernels in a plastic bag on a bamboo rack hung above the fireplace in the kitchen. A 78% of interviews households reported preserving I. wombolu kernels for less than one year while 22% preserved it for more than one year with 1.9% for two years, the normal length of the off-season period for trees in the wild. Cakes wrapped with leaves and kept on a bamboo rack hung over the fireplace were reported by households in the East and South provinces to store Irvingia gabonensis longer (more than one year. Further studies on the utilization of heat for preserving and canning bush mango kernels are recommended.

  13. Electrical insulation design and evaluation of 60 kV prototype condenser cone bushing for the superconducting equipment

    International Nuclear Information System (INIS)

    Highlights: •The optimum design of condenser cone cryogenic bushing was investigated. •Multi-layer aluminum foils in the bushing insulation body was designed and analyzed. •The optimum electric field distribution was selected by simulation. •The 60 kV FRP condenser cone cryogenic bushing was fabricated and tested. •BIL test corresponding to IEC 60137 was successfully performed for the bushing. -- Abstract: A cryogenic bushing is an essential component to be developed for commercial applications of high voltage (HV) superconducting devices. Due to the steep temperature gradient of the ambient of cryogenic bushing, general gas bushing adopting SF6 gas as an insulating media could not be directly used due to the freezing of SF6 gas. Therefore, condenser type bushing with special material considering cryogenic environment would be better choice for superconducting equipment. Considering these circumstance, we focused on the design of condenser bushing made of fiber reinforced plastic (FRP). In case of the design of the condenser bushing, it is very important to reduce the electric field intensification on the mounted flange part of the cryostat, which is the most vulnerable part of bushings. In this paper, design factors of cryogenic bushing were analyzed, and finally 60 kV condenser bushing was fabricated and tested. In order to achieve optimal electric field configuration, the configuration of condenser cone was determined using 2D electric field simulation results. Based on the experimental and the analytical works, 60 kV FRP condenser bushing was fabricated. Finally, the fabricated condenser bushing has been tested by applying lightning impulse and AC overvoltage test. From the test results, it was possible to get satisfactory results which confirm the design of cryogenic bushing in cryogenic environment

    2015-12-01

    Bush encroachment describes a global problem which is especially facing the savanna ecosystem in Africa. Livestock is directly affected by decreasing grasslands and inedible invasive species which defines the process of bush encroachment. For many small scale farmers in developing countries livestock represents a type of insurance in times of crop failure or drought. Among that bush encroachment is also a problem for crop production. Studies on the mapping of bush encroachment so far focus on small scales using high-resolution data and rarely provide information beyond the national level. Therefore a process chain was developed using a multi-scale approach to detect bush encroachment for whole Africa. The bush encroachment map is calibrated with ground truth data provided by experts in Southern, Eastern and Western Africa. By up-scaling location specific information on different levels of remote sensing imagery - 30m with Landsat images and 250m with MODIS data - a map is created showing potential and actual areas of bush encroachment on the African continent and thereby provides an innovative approach to map bush encroachment on the regional scale. A classification approach links location data based on GPS information from experts to the respective pixel in the remote sensing imagery. Supervised classification is used while actual bush encroachment information represents the training samples for the up-scaling. The classification technique is based on Random Forests and regression trees, a machine learning classification approach. Working on multiple scales and with the help of field data an innovative approach can be presented showing areas affected by bush encroachment on the African continent. This information can help to prevent further grassland decrease and identify those regions where land management strategies are of high importance to sustain livestock keeping and thereby also secure livelihoods in rural areas.

    The objectives of this research program were to reduce the manufacturing costs of variable stator vane bushings by 1) eliminating the expensive carbon fiber braiding operation, 2) replacing the batch mode impregnation, B-stage, and cutting operations with a continuous process, and 3) reducing the molding cycle and machining operations with injection molding to achieve near-net shapes. Braided bushings were successfully fabricated with both AMB-17XLD and AMB-TPD resin systems. The composite bushings achieved high glass transition temperature after post-cure (+300 C) and comparable weight loss to the PNM-15 bushings. ANM-17XLD bushings made with "batch-mode" molding compound (at 0.5 in. fiber length) achieved a +300 lb-force flange break strength which was superior to the continuous braided-fiber reinforced bushing. The non-MDA resin technology developed in this contract appears attractive for bushing applications that do not exceed a 300 C use temperature. Two thermoplastic polyimide resins were synthesized in order to generate injection molding compound powders. Excellent processing results were obtained at injection temperatures in excess of 300 C. Micro-tensile specimens were produced from each resin type and the Tg measurements (by TMA) for these samples were equivalent to AURUM(R). Thermal Gravimetric Analysis (TGA) conducted at 10 C/min showed that the non-MDA AMB-type polyimide thermoplastics had comparable weight loss to PMR-15 up to 500 C.

    Increasing Australian bush-fire frequencies over the last decade has indicated a major climatic change in coming future. Understanding such climatic change for Australian bush-fire is limited and there is an urgent need of scientific research, which is capable enough to contribute to Australian society. Frequency of bush-fire carries information on spatial, temporal and climatic aspects of bush-fire events and provides contextual information to model various climate data for accurately predicting future bush-fire hot spots. In this study, we develop an ensemble method based on a two-layered machine learning model to establish relationship between fire incidence and climatic data. In a 336 week data trial, we demonstrate that the model provides highly accurate bush-fire incidence hot-spot estimation (91% global accuracy) from the weekly climatic surfaces. Our analysis also indicates that Australian weekly bush-fire frequencies increased by 40% over the last 5 years, particularly during summer months, implicating a serious climatic shift.

  18. A Study on the Body Insulators for the Bushing for HTS Devices at Cryogenic Temperature

    Science.gov (United States)

    Kim, W. J.; Shin, H. S.; Kim, S. H.

    A bushing for high temperature superconducting devices (HTS bushing) is important because of applying high voltage to the cable or the winding of the transformer. It is cooled with liquid nitrogen (LN2) and is insulated with various insulators. For the development of the HTS bushing, it is necessary to know the fundamental characteristics of various insulators at cryogenic temperature. The electrical characteristics of the breakdown were studied under AC and impulse voltages. Also, the mechanical characteristics such as tensile strength in air and LN2 were studied. It was confirmed that GFRP is excellent not only electrical characteristics but also mechanical characteristics in LN2.

    The work proposes the application of neural networks with particle swarm optimisation (PSO) and genetic algorithms (GA) to compensate for missing data in classifying high voltage bushings. The classification is done using DGA data from 60966 bushings based on IEEEc57.104, IEC599 and IEEE production rates methods for oil impregnated paper (OIP) bushings. PSO and GA were compared in terms of accuracy and computational efficiency. Both GA and PSO simulations were able to estimate missing data values to an average 95% accuracy when only one variable was missing. However PSO rapidly deteriorated to 66% accuracy with two variables missing simultaneously, compared to 84% for GA. The data estimated using GA was found to classify the conditions of bushings than the PSO.

    Rokunohe, Toshiaki; Kato, Tatsuro; Hirose, Makoto; Ishiguro, Tetsu

    As for gas insulated switchgear (GIS), small space requirement and economical efficiency have been demanded. Circuit breakers (CB), disconnecting switches (DS) and earthing switches (ES) have been designed toward compactness. Compact & light bushings have been also required. As for bushings of GIS, there are roughly three types; capacitor, gas-filled and molding bushings. Since gas-filled bushings have the feature which is both of the lightness and the economical efficiency, it is important to develop compact and light gas-filled bushings by improvement of insulation technology. The main subject for compact design is reduction of electric field strength on the outside hollow insulator around the inside grounded electrode tip. We devised a new inner grounded electrode structure which consists of some column electrodes. This paper describes the effect of reduction of maximum value of electric field strength on the outside hollow insulator by a new inner grounded electrode. Then, improvement of insulation performance for electrodes with insulation coating in SF6 gas is described as composite insulation technology. Finally, the efficacy of these insulation technologies is described by fundamental insulation test results of prototype compact 800kV SF6 gas-filled bushing.

  7. Abnormality of transformer bushing for JT-60 power supply converter and countermeasures

    International Nuclear Information System (INIS)

    The power source for JT-60 poloidal magnetic coils (P power source) is the facility for exciting, maintaining and controlling plasma current and controlling the position and shape of plasma. The structure of the P power source is shown. The secondary side bushing of the transformer for the thyristor converter is so designed as to withstand the large current of 20-25 kA, but the cracking and oil leak occurred in the bushing insulator tubes. In order to investigate this cause, the various tests were carried out. Abnormality was not observed in the observation of the fractured surfaces, the strength test of the insulation tubes and the X-ray inspection of alien substance mixing. The stress in the bushing at the time of tightening bolts was analyzed by finite element method. As the result, there were some parts where the allowable stress of the insulator tubes was exceeded, and those agreed with the parts where fracture occurred. The new supporting fittings for the bushings were made and replaced. The transformer and its rating, the transformer secondary side bushing and an example of its cracking and the investigation of the cause of the cracking of the bushing insulator tubes are reported.

    Biodiversity is threatened by the loss and fragmentation of habitats. The role of hedgerows in maintaining biodiversity is well established, but few studies have addressed the importance for biodiversity of the intrinsic characteristics of hedgerows and the quality of hedgerow networks along a spatial scale. We examined three quality indices providing information at different territorial levels: density in the landscape, structural diversity and wood production. We performed an acoustic survey in a grassland to estimate the species abundance and community composition of bats (9 taxa) and bush crickets (11 species). Using an approach based on species and traits, we assessed how hedgerow quality influenced the activity of these taxa at different spatial scales (from 50 to 1000 m) and focused on three types of traits: bush cricket mobility ability, bat foraging strategy and habitat specialization. In general, our results showed the importance of hedgerow quality for bats and bush crickets, but the strength of the association between taxa and hedgerows varied substantially among the species and the spatial scales. Although it depends on the taxa, the production, density and structural diversity of hedgerows each had an overall positive effect. Our results suggested that these effects were generally more important at large scales. The scale effect of the production index is the best predictor of activity for bat and bush cricket taxa and traits. Our results showed the importance of hedgerow quality for the ecology of bat and bush cricket communities and could be used to improve conservation management.

  9. The essential role of democracy in the Bush Doctrine: the invasions of Iraq and Afghanistan

    Full Text Available Everyone knows that democracy played a role in the Bush Doctrine. What not everyone knows is that this role was essential for the doctrine to be put into operation under which the Iraq invasion was prepared and launched. We argue moreover that, even if aggressive, the Bush doctrine is compatible with the American Liberal Tradition. To demonstrate these arguments we analyze the links between democracy, security, and the US national interests as expressed in the pillars of the American foreign policy since the end of Cold War. The consequential belief of the Bush Administration on the positive effect of exporting democracy by the use of force to Afghanistan and Iraq to fight terrorism will be remarked. It will be shown, however, that in the first years of the Bush Administration, among the justifications for the military interventions in the two countries, security reasons prevailed over democratic concerns, although the latter was significantly present since the early hours after September 11. It was only when it became clear that WMDs did not exist in Iraq that the exporting of democracy as the ultimate weapon to fight terrorism grew remarkably and prevailed over security reasons to invade those rogue states. The paper uses quantitative and qualitative content analysis of the speeches of President Bush and his Secretaries of State and Defense.

  10. Application of desirability function for optimizing the performance characteristics of carbonitrided bushes

    2013-06-01

    Full Text Available The performance of a product is generally characterized by more than one response variable. Hence the management often faces the problem of simultaneous optimization of many response variables. This study was undertaken to simultaneously optimize the surface hardness and case depth of carbonitrided bushes. Even though lots of literature has been published on various methodologies for tackling the multi-response optimization problem, the simultaneous optimization of heat treated properties of carbonitrided bushes are not reported yet. In this research the effect of four factors and two interactions on surface hardness and case depth of carbontirded bushes were studied using design of experiments. Based on the experimental results, the expected values of the heat treated properties of the bushes were estimated for all possible combination of factors. Then the best combination which, simultaneously optimized the response variables, was arrived at using desirability function. The study showed that the optimum combination obtained through desirability function approach not only minimized the variation around the targets of surface hardness and case depth but also was superior to the ones obtained by optimizing the response variables separately. Moreover this study provides a useful and effective approach to design the production process to manufacture bushes with customer specified surface hardness and case depth targets.

Les FBI constituent une rupture avec la tradition monétariste reaganienne, même si elles s’appuient sur le rejet de l’État et la réduction du budget social. Le rôle des FBI est d’aider les organisations caritatives, notamment religieuses, à s’investir davantage dans le travail social.  Le bilan de la politique sociale de G. Bush est plutôt mitigé. La pauvreté a fortement augmenté et les promesses budgétaires en faveur des Faith-Based Organizations n’ont pas été tenues. Pire, les accusations contre les dérives des FBI fusent.

The role of the FBI is to help charities, in particular religious organizations, to invest more in social work. On the whole, the social policy implemented during the Bush years is evaluated negatively. Poverty increased rapidly and the financial promises in favor of the Faith-Based Organizations were not kept. Worse, new revelations have been disclosed. The Bush administration is accused of having used the FBI and public money to make political gains and set up an obscure funding system that benefited the Republicans and their political allies.

    Sliney, H. E.

    1984-01-01

    Two different polyimide polymers were studied and the effectiveness of a design feature to improve retention of the self lubricating composite liners under high load was evaluated. The basic bearing design consisted of a molded layer of chopped graphite-fiber-reinforced-polyimide (GFRP) composite bonded to the bore of a steel bushing. The friction, wear, and load carrying ability of the bushings were determined in oscillating tests at 25, 260 and 315 C at radial unit loads up to 260 MPa. Friction coefficients were typically 0.15 to 0.25. Bushings with liners containing a new partially fluorinated polymer were functional, but had a lower load capacity and higher wear rate than those containing a more conventional, high temperature polyimide. The liner retention design feature reduced the tendency of the liners to crack and work out of the contact zone under high oscillating loads.

  12. Applicability of fiber model in seismic response analysis for center-clamp type bushings on transformers

    International Nuclear Information System (INIS)

    A bushing is a device for insulation and support of a conductor. Especially it is called center-clamp type when it is connected with a metal holder through clamping force. As a consequence of damage of center-clamp type bushings in Tohoku Earthquake in 2011, refinement of the response analysis method and review of the seismic design procedure became necessary. In the present report, the fiber model, which can evaluate non-linear behavior in the section subjected to axial force and bending moment, was implemented to the CRIEPI's finite element analysis program 'Mastrd' considering following characteristics of center-clamp type bushings. a) The gasket section between a porcelain tube and a metal holder has a torus shape. b) Springs around the top of the bushing give clamping force, but they lock in excessive base rotation. c) The gasket does not resist against tension. d) Local resistance against compression due to bending increases in use of very thin gaskets. The developed program was verified through comparison with the shaking table test result for real bushings whose voltage classes were 154 kV and 275 kV. Deformation indices as rotation angle and base opening due to bending were influenced by damping conditions. Though there was not the condition which brought about remarkable underestimation, reduction of damping for a fiber model element was preferable for safety. On the other hand, bending moment was consistent with experimental results because it tended not to fluctuate in the non-linear region. (author)

    The cryogenic high voltage bushing for a 154 kV/100 MVA high temperatures superconducting (HTS) transformer is described. The bushing is energized with the line-to-ground voltage between the coaxial center and outer surrounding conductors, in the axial direction there is a temperature difference between ambient and 77 K. Therefore, it has to endure for electrical insulation as well as the thermal contraction as well. In this research, the electrical insulation characteristics of GFRP to achieve high durability in the cryogenic environment were surveyed in the air and LN{sub 2}. Moreover, the insulation constructions of the commercial condenser type bushing were studied. Based on these data, the electrical insulation design of the cryogenic condenser type bushing for a 154 kV class HTS transformer was performed.

  15. Research on the electrical insulation design of a bushing for a 154 kV class HTS transformer

    International Nuclear Information System (INIS)

    The cryogenic high voltage bushing for a 154 kV/100 MVA high temperatures superconducting (HTS) transformer is described. The bushing is energized with the line-to-ground voltage between the coaxial center and outer surrounding conductors, in the axial direction there is a temperature difference between ambient and 77 K. Therefore, it has to endure for electrical insulation as well as the thermal contraction as well. In this research, the electrical insulation characteristics of GFRP to achieve high durability in the cryogenic environment were surveyed in the air and LN2. Moreover, the insulation constructions of the commercial condenser type bushing were studied. Based on these data, the electrical insulation design of the cryogenic condenser type bushing for a 154 kV class HTS transformer was performed

    2016-06-01

    The dynamic stiffness properties of automotive hydraulic bushings exhibit significant amplitude sensitivity which cannot be captured by linear time-invariant models. Quasi-linear and nonlinear models are therefore proposed with focus on the amplitude sensitivity in magnitude and loss angle spectra (up to 50 Hz). Since production bushing model parameters are unknown, dynamic stiffness tests and laboratory experiments are utilized to extract model parameters. Nonlinear compliance and resistance elements are incorporated, including their interactions in order to improve amplitude sensitive predictions. New solution approximations for the new nonlinear system equations refine the multi-term harmonic balance term method. Quasi-linear models yield excellent accuracy but cannot predict trends in amplitude sensitivity since they rely on available dynamic stiffness measurements. Nonlinear models containing both nonlinear resistance and compliance elements yield superior predictions to those of prior models (with a single nonlinearity) while also providing more physical insight. Suggestion for further work is briefly mentioned.

    Seismic damage data and experiences on power transformers at home and abroad indicate that the destruction type of high-power transformers is various and the vulnerability is very high. Furthermore, the post-disaster reconstruction of transformers, which needs a long recovery cycle and a high cost, will be very difficult. Studies have shown that the acceleration response of the transformer and bushings will be quickly reduced and seismic reliability of transformer will be improved because there is one seismic isolation layer between the bottom of transformer tank and the base which form the seismic isolation system of the transformer and bushings (SISTB). But isolation layer design and parameters selection of SISTB have larger difference with general structures.

    Full Text Available Nectar production and the morphology of the nectary and pollen grains of Kolwitzia amabilis Graebn. were studied during the period 2008–2009 and in 2011. The blooming of beauty bush flowers started in the third decade of May and ended in the middle of June; flowering lasted 22–23 days. The flower life span was 4–5 days. Nectar production began at the bud break stage. The tube of the corolla in beauty bush flowers forms a spur inside which the nectary is located. The secretory surface of the nectary consists of two layers of glandular epidermal outgrowths: unicellular trichomes, with their length ranging 54.6 μm – 70.2 μm, and papillae with a length of 13.0 μm – 20.6 μm. The mean weight of nectar per 10 flowers, determined for the three years of the study, was 8.6 mg, with a sugar concentration of 50.8%. The weight of nectar sugar was on average 4.4 mg. In terms of the size, beauty bush pollen grains are classified as medium-sized. These are tricolporate grains.

    The power transformer is the key equipment of the power system; its insulation condition will directly influence the security and reliability of the power system. Thus, the on-line monitoring of power transformer is urgently required in order to guarantee the normal operation of the power system. Moreover, the dielectric loss factor is a significant parameter reflecting the condition of transformer bushing, so the on-line measurement of dielectric loss factor is really important. In this paper, the phase-to-phase comparison method is selected as the on-line monitoring method based on the overall analysis and discussion of the existing on-line monitoring methods. At first, the harmonic analysis method is utilized to calculate the dielectric loss of each phase of the three-phase transformer bushing, and then the differences of dielectric loss between every two phases are calculated and analyzed. So the insulation condition of each bushing could be achieved based on the careful analysis of different phase-to-phase dielectric loss. The simulation results of phase-to-phase comparison method are carried out in this paper, and the validity is verified. At last, this method is utilized in an actual equipment of on-line monitoring.

  9. Accumulation of atmospheric deposition of As, Cd and Pb by bush bean plants

    International Nuclear Information System (INIS)

    Bush bean (Phaseolus vulgaris) was exposed to atmospheric deposition of As, Cd and Pb in a polluted and a reference area. The atmospheric deposition of these elements was significantly related to the concentrations in leaves, stems and pods at green harvest. Surprisingly there was also a clear relation for As and Pb in the seeds at dry harvest, even though these seeds were covered by the husks. Root uptake of accumulated atmospheric deposits was not likely in such a short term experiment, as confirmed by the fact that soil pore water analysis did not reveal significant differences in trace element concentrations in the different exposure areas. For biomonitoring purposes, the leaves of bush bean are the most suitable, but also washed or unwashed pods can be used. This means that the obtained relationships are suitable to estimate the transfer of airborne trace elements in the food chain via bush bean. - Highlights: • Atmospheric deposition of trace elements accumulates in bean leaves, stems and pods. • Also thoroughly washed green pods are suitable for biomonitoring. • Even the non-exposed bean seeds accumulate As and Pb deposits to some extend. • A migration of trace elements from the husks to the seeds is most likely. - In a polluted area, atmospheric deposition of trace elements on the above-ground plant parts is influencing their concentration, even in the seeds

    Full Text Available Abstract Introduction Though animal-related injuries and fatalities have been documented throughout the world, the variety of attacks by wild animals native to rural East Africa are less commonly described. Given the proximity of our northwestern Tanzania hospital to Lake Victoria, Lake Tanganyika, and the Serengeti National Park, and presentation of several patients attacked by bush animals and suffering a variety of complex injuries, we sought to report the pattern of attacks and surgical management in a resource-limited setting. Materials and methods Four patients who were admitted to the northwestern Tanzania tertiary referral hospital, Bugando Medical Centre (BMC, in 2010-2011 suffered attacks by different bush animals: hyena, elephant, crocodile, and vervet monkey. These patients were triaged as trauma patients in the Casualty Ward, then admitted for inpatient monitoring and treatment. Their outcomes were followed to discharge. Results The age and gender of the patients attacked was variable, though all but the pediatric patient were participating in food gathering or guarding activities in rural locations at the time of the attacks. All patients required surgical management of their injuries, which included debridement and closure of wounds, chest tube insertion, amputation, and external fixation of an extremity fracture. All patients survived and were discharged home. Discussion Though human injuries secondary to encounters with undomesticated animals such as cows, moose, and camel are reported, they often are indirect traumas resulting from road traffic collisions. Snake attacks are well documented and common. However, this series of unique bush animal attacks describes the initial and surgical management of human injuries in the resource-limited setting of the developing world. Conclusion Animal attacks are common throughout the world, but their pattern may vary in Africa throughout jungle and bush environmental settings. It is

    An online partial discharge (PD) measurement performed on a high voltage direct current (HVDC) wall bushing successfully identified the presence of internal discharges. The wall bushing is a sulfur hexafluoride gas-insu- lated bushing, rated for 500 kV dc and terminated on a thyristor-controlled HVDC converter bridge. The measure- ment of PD within the HVDC station environment is particularly challenging due to the high levels of electromagnetic noise caused by thyristor switching events and external air-corona from the neighboring high-voltage equipment. An additional challenge is the "mixed" voltage stress on the bushing insulation, which has both ac and dc high-voltage components. There are also fast transients during the firing of thyristors in the HVDC conversion process that cause added stress to the insulation. As a result, the analysis and interpretation of PD data for HVDC equipment is more complex; PD pulses may occur in response to the ac, dc, or switching transient voltage stresses. In this paper, an on- line PD measurement strategy for noise filtering and isolation of PD sources within the bushing are discussed. The PD measurement data is plotted on a phase-resolved diagram where the line supply power cord voltage was used as a reference. The phase-resolved diagram appears to suggest that the fast transients, caused during switching, trigger some PD events. Measurements were also performed with the aid of a modern PD measurement instrument having noise separation capabilities. The findings from the online PD measurements are verified with physical evidence, found after the bushing was removed from service, suggested internal PD had occurred inside the bushing.

  12. Design and development of CRIO based data acquisition and control system for high voltage bushing experiment

    International Nuclear Information System (INIS)

    In Diagnostic Neutral Beam (DNB), High Voltage (HV) bushing is an interface between the HV transmission line and Beam source. For validating the design of HVB of DNB, a scaled down configuration of the Bushing is fabricated, referred to as PHVB and assembled. This PHVB is to be subjected to long duration HV tests up to 60 kV under vacuum conditions for verifying the voltage holding capacity of the bushing. For automating the entire experimental process of HVB experiment and acquiring important experimental data up to 3600 sec for post analysis, a dedicated Data Acquisition and Control System (DACS) is required. This will help in understanding the behavior of the PHVB in High voltage and vacuum environment. Also it is required that high speed breakdown events are monitored. CRIO (compact reconfigurable input output) is a rugged, small sized hardware platform which combines the power of real time processor and FPGA bus. It is becoming an upcoming standard for medium sized experiment. For ensuring smooth control operation of the experiment; NI CRIO was selected as the controller for DACS. In this experiment the CRIO provides a user interface for setting of important control set points of power supply and vacuum system. Also it provides seamless control and acquisition for pulse durations of up to 3600 sec. The voltage signal is generated as a ramp signal with upper voltage set point. The ramp rate applied is 1.5 kV/min and is user configurable. The testing of PHVB has been successfully completed using the developed DACS. In this paper the technical details of DACS design, implementation and test results shall be discussed. (author)

    Full Text Available Bush rose architecture, among other factors, such as plant health, determines plant visual quality. The commercial product is the individual plant and interplant variability may be high within a crop. Thus, both mean plant architecture and interplant variability should be studied. Expansion is an important feature of architecture, but it has been little studied at the level of individual organs in bush roses. We investigated the expansion kinetics of primary shoot organs, to develop a model reproducing the organ expansion of real crops from non destructive input variables. We took interplant variability in expansion kinetics and the model’s ability to simulate this variability into account. Changes in leaflet and internode dimensions over thermal time were recorded for primary shoot expansion, on 83 plants from three crops grown in different climatic conditions and densities. An empirical model was developed, to reproduce organ expansion kinetics for individual plants of a real crop of bush rose primary shoots. Leaflet or internode length was simulated as a logistic function of thermal time. The model was evaluated by cross-validation. We found that differences in leaflet or internode expansion kinetics between phytomer positions and between plants at a given phytomer position were due mostly to large differences in time of organ expansion and expansion rate, rather than differences in expansion duration. Thus, in the model, the parameters linked to expansion duration were predicted by values common to all plants, whereas variability in final size and organ expansion time was captured by input data. The model accurately simulated leaflet and internode expansion for individual plants (RMSEP = 7.3% and 10.2% of final length, respectively. Thus, this study defines the measurements required to simulate expansion and provides the first model simulating organ expansion in rosebush to capture interplant variability.

    Brahman x Hereford cattle carried only one-quarter as many engorging adult bush ticks (Haemaphysalis (Kaiseriana) longicornis) as Hereford. Simmental x Hereford or Friesian x Hereford cattle when grazed together on the north coast of New South Wales. Fourteen percent of a Brahman x Hereford herd carried half of the engorging ticks suggesting that infestation levels would be further reduced by culling procedures. The results indicate an additional advantage to those already established for Brahman x Hereford cattle on the north coast of New South Wales and have important implications for tick control.

    Full Text Available Despite interest in the relationship between fluctuating asymmetry (FA, immune response and ecological factors in insects, little data are available from wild populations. In this study we measured FA and immune response in 370 wild-caught male bush-crickets, Metrioptera roeseli, from 20 experimentally introduced populations in southern-central Sweden. Individuals with more-symmetric wings had a higher immune response as measured by the cellular encapsulation of a surgically-implanted nylon monofilament. However, we found no relationship between measures of FA in other organs (i.e. tibia and maxillary palp and immune response, suggesting that this pattern may reflect differing selection pressures.

    Full Text Available Este artículo examina el porqué el presidente George W. Bush no pudo recolectar la ayuda de la ciudadanía americana para su estrategia para la estabilización y la transformación de Iraq. De hecho, esta estrategia ha sido afectada por el desplegar de los acontecimientos que sucedieron en Iraq, pero el problema principal reside en las posiciones que el presidente utilizó para simplificar los desafíos que el ejército americano y la diplomacia tenían que hacer frente en Iraq, buscando la aprobación de las criticas periodisticas, de los expertos gubernamentales y de los juristas. En más de una perspectiva la falta de aprobación del gobierno Bush en Iraq es una consecuencia de la carencia de la confianza que la opinión pública tuvo por su presidente y sus consejeros para lograr sus objetivos en Iraq. Para constatar esta tesis, el artículo analiza el discurso del presidente a la nación, difundida en horario de punta el 28 de julio de 2005, que demuestra que los americanos no estaban demasiado convencidos de la estrategia de Bush._____________ABSTRACT:This article puts in context why President of the United States of America George W. Bush has been unable to rally American support for his strategy to stabilize and transform Iraq. Since the summer of 2003, when Iraqis started to challenge the authority of the Anglo-American occupation, the White House has been on the defensive, while American support for post-war efforts has dwindled. While developments in Iraq have affected the strategy’s execution, the main problem is the president’s inclination to oversimplify the challenges American troops and diplomats are facing in Iraq, inviting criticism from journalists, experts on nation-building and lawmakers. In many ways, declining approval of Bush’s handling of Iraq results in the public’s lack of confidence that the president and his advisors will be able to accomplish its goals in Iraq. To test this argument, the article analyzes

    The event bush is a new formalism for organizing knowledge in various fields of geoscience, particularly suitable for hazard assessment purposes. Acting as an intermediary between expert knowledge and the well-established field of Bayesian belief networks, the event bush allows at the same time a variety of other applications, linking geoscientific knowledge to the field of artificial intelligence and uniting probabilistic, deterministic, and fuzzy approaches. In this paper, we present basic principles, mathematical formulation, guidelines for application, and examples, including the connection with Bayesian belief networks. Further development of the method will include spatial and temporal modelling, implementation in mapping in GIS medium, formalization by means of predicate logic, definition of variable states in BBNs by membership functions based on the event bush semantics, and other applications.

    International Nuclear Information System (INIS)

    The computer code BUSH has been developed for the calculation of steady state heat transfer in a rod bundle. For a given power, flow and geometry it can calculate the temperatures in the rods, coolant and shroud assuming that at any axial level each rod can be described by one temperature and the coolant fluid is also radially uniform at this level. Heat transfer by convection and radiation are handled and the geometry is flexible enough to model nearly all types of envisaged shroud design for the SUPERSARA test series. The modular way in which BUSH has been written makes it suitable for future development, either within the present BUSH framework or as part of a more advanced code

  4. Effects of high fire frequency in creosote bush scrub vegetation of the Mojave Desert

    2012-01-01

    Plant invasions can increase fire frequency in desert ecosystems where fires were historically infrequent. Although there are many resource management concerns associated with high frequency fire in deserts, fundamental effects on plant community characteristics remain largely unstudied. Here I describe the effects of fire frequency on creosote bush scrub vegetation in the Mojave Desert, USA. Biomass of the invasive annual grass Bromus rubens L. increased following fire, but did not increase further with additional fires. In contrast, density, cover and species richness of native perennial plants each decreased following fire and continued to decrease with subsequent fires, although not as dramatically as after the initial fire. Responses were similar 5 and 14 years post-fire, except that cover of Hymenoclea salsola Torr. & A. Gray and Achnatherum speciosa Trin. & Rupr. both increased in areas burnt once. These results suggest that control of B. rubens may be equally warranted after one, two or three fires, but revegetation of native perennial plants is most warranted following multiple fires. These results are valid within the scope of this study, which is defined as relatively short term vegetation responses (???14 years) to short fire return intervals (6.3 and 7.3 years for the two and three fire frequency levels) within creosote bush scrub of the Mojave Desert. ?? 2012 IAWF.

  5. Fluid technologies: The Bush Pump, the LifeStraw and microworlds of humanitarian design.

    2016-04-01

    Over the past decade, many ingenious, small-scale gadgets have appeared in response to problems of disaster and extreme poverty. Focusing on the LifeStraw, a water filtration device invented by the company Vestergaard Frandsen, I situate this wave of humanitarian design relative to Marianne de Laet and Annemarie Mol's classic article on the Zimbabwe Bush Pump. The LifeStraw shares the Bush Pump's principle of technical minimalism, as well as its ethical desire to improve the lives of communities. Unlike the pump, however, the straw defines itself through rather than against market logic, accepting the premise that one can 'do well while doing good'. Moreover, it does not share the assumed framework of de Laet and Mol's Zimbabwean socio-technical landscape: a postcolonial state happily en route to national self-definition. Nonetheless, it clearly embodies moral affect, if in the idiom of humanitarian concern rather than development. My aim is to open up three interrelated lines of inquiry for discussion. First, I consider aspects of a postcolonial condition at the micro-level of immediate needs, including assumptions about nation-state politics and markets. Second, I emphasize science and technology in the form of infrastructure, the material frontline of norms.

    In South Africa, Athrixia phylicoides DC. (bush tea) is widely used as a beverage, cough remedy and purgative. The commercialization of this tea in a similar vein to rooibos (Aspalathus linearis), is being considered. Traditional infusions and decoctions, as well as water and ethanol extracts, were prepared and screened. A related species, Athrixia elata Sond. (daisy tea), was included in many of the assays as a comparison. Extracts of Athrixia phylicoides and Athrixia elata were tested for toxic effects to brine shrimp larvae and the Vero kidney cell line. In both assays, the traditional preparations and aqueous extracts had little effect, but the ethanol extracts were relatively toxic. Antioxidant activity comparable to that found in rooibos was established. No detectable levels of caffeine were present in the Athrixia extracts following analysis using TLC and I/HCl spray reagent. Neither screening using spectrophotometry nor confirmation using gas chromatography-mass spectrometry analyses showed evidence of pyrrolizidine alkaloids in Athrixia phylicoides. Although a wider range of studies needs to be conducted prior to commercialization, these results support the development of bush tea as a healthy alternative to caffeine-containing beverages.

    This investigation pertains to the examination of the sliding wear behavior of a leaded-tin bronze bushing under the conditions of varying applied loads and test environments against a steel shaft. The test environment was changed by adding 5% of solid lubricants like talc and lead to an oil lubricant separately as well as in combination; the fraction of the two (solid) lubricants within the solid lubricant mixture was varied in the range of 25-75% in the latter case. The wear performance of the bushing was characterized in terms of the wear rate, frictional heating, and friction coefficient. The increasing load led to deterioration in the wear response, while the addition of the solid lubricant particles produced a reverse effect. Further, an appreciable difference in the wear behavior was not observed when the tests were conducted in the oil plus talc and oil plus lead lubricant mixtures. However, the oil containing lead and talc together brought about a significant improvement in the wear response; best results were obtained in the case of the lubricant mixture consisting of lead and talc together in the ratio of 3:1 in the oil. The observed wear behavior of the samples has been discussed in terms of specific characteristics of various microconstituents. The features of the wear surfaces and subsurface regions further substantiated the wear response and enabled us to understand the operating material removal mechanisms.

  8. Design optimization of the 100 kV HV bushing for ITER-DNB

    International Nuclear Information System (INIS)

    The 100 kV bushing of the Diagnostic Neutral Beam (DNB) injector is a cylindrical feedthrough which forms the interface between the gas insulated transmission line and the torus primary vacuum and provides all necessary services to the beam source. All conventions for safety, voltage holding requirement, vacuum compatibility and the choice of materials have been addressed in the design. Finite Element Analyses (FEAs) for the electrostatic and the structural configuration is carried out to validate the design of the High Voltage Bushing (HVB). Several iterations and optimizations of the stress shields are carried out to meet electrostatic criteria, especially at the triple point (the ceramic, metal and vacuum joint), which is critical for good voltage holding. Structural analyses is carried out to assess the stress distribution in the fiber reinforced plastic insulator, the alumina insulator and the integrated HVB for different load cases like operational orientation (horizontal), normal operation and accidental case. Design is further validated for seismic conditions for Seismic Loading-2 (SL-2).

    Geophysical studies have been conducted at five sites in the southern Bush River Peninsula in the Edgewood Area of Aberdeen Proving Ground, Maryland. The goals of the studies were to identify areas containing buried metallic objects and to provide diagnostic signatures of the hydrogeologic framework of the site. These studies indicate that, during the Pleistocene Epoch, alternating stands of high and low sea level resulted in a complex pattern of channel-fill deposits. Paleochannels of various sizes and orientations have been mapped throughout the study area by means of ground-penetrating radar and EM-31 techniques. The EM-31 paleochannel signatures are represented onshore either by conductivity highs or lows, depending on the depths and facies of the fill sequences. A companion study shows the features as conductivity highs where they extend offshore. This erosional and depositional system is environmentally significant because of the role it plays in the shallow groundwater flow regime beneath the site. Magnetic and electromagnetic anomalies outline surficial and buried debris throughout the areas surveyed. On the basis of geophysical measurements, large-scale (i.e., tens of feet) landfilling has not been found in the southern Bush River Peninsula, though smaller-scale dumping of metallic debris and/or munitions cannot be ruled out.

    The historical processes underlying high diversity in tropical biodiversity hotspots like the Western Ghats of Peninsular India remain poorly understood. We sampled bush frogs on 13 massifs across the Western Ghats Escarpment and examined the relative influence of Quaternary glaciations, ecological gradients and geological processes on the spatial patterns of lineage and clade diversification. The results reveal a large in situ radiation (more than 60 lineages), exhibiting geographical structure and clade-level endemism, with two deeply divergent sister clades, North and South, highlighting the biogeographic significance of an ancient valley, the Palghat Gap. A majority of the bush frog sister lineages were isolated on adjacent massifs, and signatures of range stasis provide support for the dominance of geological processes in allopatric speciation. In situ diversification events within the montane zones (more than 1800 m) of the two highest massifs suggest a role for climate-mediated forest-grassland persistence. Independent transitions along elevational gradients among sub-clades during the Miocene point to diversification along the elevational gradient. The study highlights the evolutionary significance of massifs in the Western Ghats with the high elevations acting as centres of lineage diversification and the low- and mid-elevations of the southern regions, with deeply divergent lineages, serving as museums.

  11. Patterns of biomediated CaCO3 crystal bushes in hot spring deposits

    2013-08-01

    In the Eryuan hot spring, located in south China, the vent pool is covered with “crystal bushes”, up to 2 cm high, 1 cm in diameter, that grew in the biofilms that thrive in the spring waters that have a pH of 7.5 and a temperature of 88 °C. The biofilms are formed largely of phototrophic purple bacteria and green bacteria. Growth of the crystal bushes, which are formed of aragonite crystals (wheat-sheaves, radiating clusters), rhombohedral and dodecahedral calcite crystals, amorphous CaCO3 (ACC), and opal-A, is attributed to precipitation in the micro-domains of the biofilms where physiochemical conditions can vary on the sub-micron scale. There is no evidence that the calcite was formed through recrystallization of the metastable aragonite and most of the calcite crystals developed as mesocrystals that are characterized by incomplete growth and porous crystal faces. With the onset of diagenesis, there is a high probability that the crystal bushes will lose much of their identity as the (1) biofilm is lost through decay, (2) ACC and aragonite change to calcite, (3) identities of the mesocrystals and incompletely formed crystals are lost through continued precipitation and/or recrystallization, and (4) porous crystal faces are converted to solid crystal faces. This means that most of the features considered indicative of biomediated calcite precipitation have a low preservation potential and that the recognition of biomediated precipitates in old spring deposits may remain problematical.

    2010-03-01

    Full Text Available For a century, scholars and labor movement activists have debated the question of “American Exceptionalism,” or the distinctive nature of the labor movement in the United States. The weakness of American unions, especially their lack of members, has been attributed to distinctive features of American society, notably the hostility of the American government towards unions. Those who accept this Exceptionalist view have urged unions in the United States to become more active politically in order to strengthen their position. Since 1980, unions have followed this advice and have doubled their political spending. Most of the unions’ political activity and spending has been in support of candidates of the Democratic Party; but unions have received little in return from Democrats, even during the Clinton Administration. Indeed, during the administration of George W. Bush, union membership fell at almost exactly the same rate as before notwithstanding the Bush Administration’s open hostility towards unions and its attempt to use state power against unions in both the private and public sectors. In fact, over the last decades, we may be seeing the end of Exceptionalism. Since 1990, union membership decline has been slower in the United States than in most other OECD member states, despite a relatively hostile political and legal regime. Combined with the negligible effect of the Bush Administration on American unions, this suggests that union weakness in the United States is not due to exceptional features of the United States but to characteristics it shares with other countries. Throughout the affluent world, the idea of the labor movement has lost its tie to the broader democratic aspirations. In America and elsewhere, union revival depends on more than some incremental legal changes or political victories. It depends on the revival of the formative ideals of the labor movement, equality, fraternity, and the struggle for free and democratic

    Bush encroachment of savannas and grasslands is a common form of land degradation in the rangelands of South Africa. To assess the carrying capacity of the land and to understand underlaying processes of bush encroachment, continuous monitoring of this phenomenon is needed. The aim of this study is to provide training sites for satellite-based monitoring of bush encroachment in South Africa on a medium spatial resolution satellite sensor (e.g. MODIS or Landsat) scale. Since field surveys are time consuming and of limited spatial extent, the satellite based creation of training sites using Google Earth images is intended. Training pixels for woody vegetation and non-woody land cover were manually digitized from 50 sample Google Earth images. A Random Forests model was trained to delineate woody from non-woody pixels. The results indicate a high performance of the model (AUC = 0.97). The model was applied to a further 500 Google Earth images with a spatial extent of 250 m × 250 m. The classified images form the database of training sites which can be used for larger scale monitoring of bush encroachment in South Africa.

  16. Evaluation of DFIR and Bush Gauge Snowfall Measurements at Boreal Forest Sites in Saskatchewan/Canada and Valdai/Russia

    Snowfall is important to cold region climate and hydrology including Canada. Large uncertainties and biases exist in gauge-measured precipitation datasets and products. These uncertainties affect important decision-making, water resources assessments, climate change analyses, and calibrations of remote sensing algorithms and land surface models. Efforts have been made at both the national and international levels to quantity the errors/biases in precipitation measurements, such as the WMO Solid Precipitation Intercomparison Experiment (WMO-SPICE). Both the DFIR (double fence intercomparison reference) and the bush shielded gauge have been used in the past as a reference measurement for solid precipitation and they both have been selected as the references for the current SPICE project. Previous analyses of the DFIR vs. the bush (manual Tretyakov) gauge data collected at the Valdai station in Russia suggest DFIR undercatch of snowfall by up to 10% for high wind conditions. A regression relationship between the 2 systems was derived and used for the last WMO gauge intercomparison. Given the importance of the DFIR as the reference for the WMO SPICE project, it is necessary to re-examine and update the DFIR and bush gauge relationship. As part of Canada's contribution to the WMO SPICE project, a test site has been set up by EC/ASTD/WSDT in the southern Canadian Boreal forest to compare the DFIR and bush gauges. This site, called the Caribou Creek, has been installed within a modified young Jack Pine forest stand - north of Prince Albert in Saskatchewan. This study compiles and analyzes recent DFIR and bush gauge data from both the Valdai and Caribou Creek sites. This presentation summarizes the results of data analyses, and evaluates the performance of both references for snowfall observations in the northern regions. The methods and results of this research will directly support the WMO SPICE project and contribute to cold region hydrology and climate change research.

    Bush encroachment of rangelands in South Africa is a common form of land degradation with negative economic consequences. A monitoring of bush encroachment is needed for several reasons: on the one hand, it allows farmers to identify locations with upcoming bushes which gives them a tool for management (e.g. poisoning of bushes) and would further allow them to assess the current carrying capacity of their land. On the other hand, it serves scientists as a baseline to reveal the still unknown causes of bush encroachment. This study aimed at providing training sites applicable for a satellite-based monitoring of woody vegetation in South Africa on the scale of medium spatial resolution satellite sensors (e.g. MODIS or Landsat). Since field surveys are time consuming and only of limited spatial extent, a satellite based creation of training sites on the basis of Google Earth images was intended. In view to an automatic classification of the Google Earth RGB images, training pixels for woody vegetation and non woody land cover were manually digitized from 50 example images. A Random Forests model was then trained to delineate woody from non woody pixels. With an area under the ROC-curve of 0.97, the model was highly able to classify the images. The model was applied to classify further 500 Google Earth images with a spatial extent of 250x250m. The classified images form the database of training sites which can be used for a MODIS based monitoring of woody vegetation in upcoming studies.

  18. Eland browsing of Grewia occidentalis in semi-arid shrubland: the influence of bush clumps

    L.H. Watson

    1999-01-01

    Full Text Available Grewia occidentalis plants in the study area generally occurred in bush clumps with other shrub species. Grewia occidentalis commonly occurred with Diospyros austro-africana, Rhus longispina and Rhus pollens (nurse shrubs, but seldom with Acacia kar-roo and Lycium cinereum (non-nurse shrubs. Eland browsed G. occidentalis plants at higher levels than other shrub species, but browsing was not evenly spread across all plants. Grewia occidentalis plants associated with nurse shrubs had lower levels of browsing than those growing alone and those growing with non-nurse shrubs, while G. occidentalis plants in the centre of nurse shrubs experienced the lowest levels of browsing. The latter group of plants also produced the most fruit. Eland browsing is consid-ered an important factor determining the distribution of G. occidentalis plants in the study area, while the presence of nurse shrubs is considered essential for the establishment and maintenance of the G. occidentalis population in the study area.

    A new Australian species of functionally dioecious bush tomato of Solanum subgenus Leptostemonum is described. Solanum ossicruentum Martine & J.Cantley, sp. nov., is thought to be allied with members of the problematic "Dioicum Complex" lineage, but differs in its short silvery indumentum, long calyx lobes, larger stature, and an unusual fruit morphology that may represent "trample burr" seed dispersal. The species occurs in a range extending from the eastern Kimberley in Western Australia to far northwestern Northern Territory and has been recognized for decades as a variant of Solanum dioicum W.Fitzg. Specimens of this species were previously referred to by D.E. Symon and others as Solanum dioicum 'Tanami.' Ex situ crossing studies and SEM images of inaperturate pollen grains produced in morphologically hermaphrodite flowers indicate that this taxon is functionally dioecious. The scientific name was chosen with the help of 150 seventh grade life science students from Pennsylvania, USA. PMID:27489475

  1. Wolves at the Door: Musical persuasion in a 2004 Bush-Cheney advertisement

    Directory of Open Access Journals (Sweden)

    Matthew A. Killmeier

    2010-10-01

    Full Text Available Many journalists and scholars overlook the discursive role of music in TV political advertisements. But we argue that music is a potent means of political persuasion. Music in advertisements is determinative; all other elements—images, voiceovers, sound effects, written text, and so on—are circumscribed by the music and interpreted in relation to it. Music determines an advertisement’s character through framing and underscoring; musical frames establish interpretative categories and generate expectations, while underscoring comprises music that closely coordinates with images and voiceovers to form a persuasive aesthetic and rhetorical unity. A close reading of a 2004 Bush-Cheney advertisement applies this theory of frames and underscoring to explain the advertisement’s effectiveness. Without music, the advertisement would not only fail to persuade, it would also make no sense.

    Ostrowski, Tim Daniel; Stumpner, Andreas

    2010-08-01

    We asked how processing of male signals in the auditory pathway of the bush cricket Ancistrura nigrovittata (Phaneropterinae, Tettigoniidae) changes from the ear to the brain. From 37 sensory neurons in the crista acustica single elements (cells 8 or 9) have frequency tuning corresponding closely to the behavioral tuning of the females. Nevertheless, one-quarter of sensory neurons (approximately cells 9 to 18) excite the ascending neuron 1 (AN1), which is best tuned to the male's song carrier frequency. AN1 receives frequency-dependent inhibition, reducing sensitivity especially in the ultrasound. When recorded in the brain, AN1 shows slightly lower overall activity than when recorded in the prothoracic ganglion close to the spike-generating zone. This difference is significant in the ultrasonic range. The first identified local brain neuron in a bush cricket (LBN1) is described. Its dendrites overlap with some of AN1-terminations in the brain. Its frequency tuning and intensity dependence strongly suggest a direct postsynaptic connection to AN1. Spiking in LBN1 is only elicited after summation of excitatory postsynaptic potentials evoked by individual AN1-action potentials. This serves a filtering mechanism that reduces the sensitivity of LBN1 and also its responsiveness to ultrasound as compared to AN1. Consequently, spike latencies of LBN1 are long (>30 ms) despite its being a second-order interneuron. Additionally, LBN1 receives frequency-specific inhibition, most likely further reducing its responses to ultrasound. This demonstrates that frequency-specific inhibition is redundant in two directly connected interneurons on subsequent levels in the auditory system. PMID:20533362

  5. U.S. energy policy and the Bush administration's North American energy strategy

    International Nuclear Information System (INIS)

    This presentation outlined the energy policy in the United States and its impact on frontier development in Alaska, deepwater offshore fields and in the western oil shale resources. The energy strategy focuses on technologies that increase domestic production from existing resources as well as technologies that create new sources of energy. In addition to emphasizing the cooperation between Canada and the United States in ensuring energy supply security and stability, this paper discussed the importance of overall bilateral trade between the 2 countries. It was noted that Canada is the United State's most secure and reliable energy partner and is the number 1 supplier of imported oil, natural gas, electricity and uranium. The Bush administration's energy policy is based on the mandate to supply stable, reliable, secure, affordable and environmentally sound energy for the country's growing economy. The energy strategy focuses on increasing energy supplies, promoting energy conservation, repairing and modernizing the energy infrastructure, protecting the environment and improving energy security. Basic changes to the way energy is produced and used will be needed in order to meet these challenges. Energy security can be met through efficiency gains, diversification and use of alternative energy sources. The strategy involves a balance of supply sources, ranging from increasing domestic oil and gas production to such sources as clean coal generation, nuclear power and hydropower. The policy also balances the use of traditional energy sources with renewables such as geothermal, solar, wind and hydrogen. The United States, Canada and Mexico have identified the following 9 areas as critical for interaction on energy: energy data, electricity, regulatory cooperation, energy efficiency, natural gas, oil sands, nuclear and energy science and technology. Construction of the Alaska Natural Gas Pipeline is also one of the Bush administration's highest priorities, along with

    According to terror management theory, heightened concerns about mortality should intensify the appeal of charismatic leaders. To assess this idea, we investigated how thoughts about death and the 9/11 terrorist attacks influence Americans' attitudes toward current U.S. President George W. Bush. Study 1 found that reminding people of their own mortality (mortality salience) increased support for Bush and his counterterrorism policies. Study 2 demonstrated that subliminal exposure to 9/11-related stimuli brought death-related thoughts closer to consciousness. Study 3 showed that reminders of both mortality and 9/11 increased support for Bush. In Study 4, mortality salience led participants to become more favorable toward Bush and voting for him in the upcoming election but less favorable toward Presidential candidate John Kerry and voting for him. Discussion focused on the role of terror management processes in allegiance to charismatic leaders and political decision making. PMID:15359017

  7. The relative uptake of 237Pu(IV) and Pu(VI) oxidation states from water by bush beans

    International Nuclear Information System (INIS)

    Recent data is presented on the status of Pu oxidation states (IV) and (VI) during plant uptake from an aqueous culture. An experiment was performed with bush beans, using 237Pu, to monitor the stability of Pu(IV) and Pu(VI) in the solution phase, to evaluate the relative uptake of each oxidation state by bush beans from water, and to determine the valence of the Pu inside the vascular system by analyzing the xylem exudate. Pu(VI) in solution was assimilated by plants more rapidly than Pu(IV) but was reduced to the less biologically mobile Pu(IV) in the plant biochemical environment. Dominance of Pu(IV) in the xylem exudate indicates that Pu(VI) would not be expected to persist in vegetable matter. Therefore of the biochemically associated Pu in plant matter ingested by humans a considerably larger amount would occur as Pu(IV) than as Pu(VI). (author)

  8. Effect of DTPA on concentration ratios of 237Np and 244Cm in vegetative parts of bush bean and barley

    International Nuclear Information System (INIS)

    Bush beans (Phaseolus vulgaris L.) and barley (Hordeum vulgare L.) were grown in two different soils (noncalcareous and calcareous) in containers in a glasshouse with 530 pCi/g 237Np or 15040 pCi/g 244Cm mixed into separate containers of the soil. The chelating agent DTPA at 100 μg/g soil was added to one half of the containers. The concentration ratio (C.R.) without DTPA was two orders of magnitude higher for 237Np than for 244Cm by two and three orders of magnitude but had little influence on 237Np. For the calcareous soil with DTPA, 244Cm C.R.'s were greater than those for 237Np. In bush beans both 237Np and 244Cm C.R.'s were higher in primary leaves than in trifoliate leaves which were higher than for stems

    Many monuments and cities that are part of humanity's heritage have been built with carved granite ashlars. This dimension stone is one of the most used due to its abundance and durability. Traditional quarrymen have used anisotropic planes to cut granite blocks in the quarry for improved cutting performance. These planes are called Rift, Grain and Hardway (R, G, H) according to the ease of cutting. The aim of this study is to determine the response of each of the three orthogonal cutting planes R, G and H to the craft styling with bush hammer, based on their decay. Alpedrete granite was selected for this research, it is a monzogranite quarried in the Sierra de Guadarrana (Spanish Central System) foothills, in the province of Madrid, Spain. It is one of the most representative of Madrid's heritage granites. Alpedrete granite is also used as building stone in other European cities. From an Alpedrete granite bush hammered ashlar, three thin sections were cut parallel to the H plane; these thin sections cut R and G bush hammered planes. Also three thin sections have been cut parallel to the R plane at a distance of 2 mm, 10 mm and 30 mm from the bush hammered surface. All thin sections have been treated with fluorescein. In each of the thin sections a micrograph mosaic was performed covering the entire area (about 10 cm2, 300 photomicrographs) and printed with 120 increases. The length and spacing of inter-, intra- and trans-crystalline microcracks were quantified and measured. Microcracks were subdivided based on affected minerals in each R, G and H planes. Through these observations it was found that Alpedrete Granite R plane (easier to cut) is determined by exfoliation microcracks orientation. That is, R plane is parallel to the exfoliations microcracks, which are intra-crystalline and straight. The cutting of stones in the R plane is due to the coalescence of straight microcracks in the plane. This plane minimizes the effort and cost of subsequent carving so it

    The 'National Energy Policy' (NEP) released by the Bush Administration on May 17, 2001 was supposedly intended to meet growing U.S. energy requirements in the first two decades of the 21st Century while also diminishing U.S. dependence on imported oil. This was to be accomplished, the White House suggested, by increasing production at existing oil fields in the United States and by commencing drilling on the Artic National Wildlife Refuge (ANWR) in Alaska. So great was the furor over drilling on ANWR that most people never bothered to examine the NEP closely. This is unfortunate, as a close reading of the NEP report reveals a very different picture than that suggested by White House pronouncements: far from promoting energy 'independence', the NEP assumes that the United States will become MORE, not less dependent on imported petroleum in the years ahead and therefore calls on the Federal Government to take whatever steps are necessary to promote enhanced U.S. access to foreign oil. In particular, the NEP calls on the U.S. Government to seek additional petroleum from the Persian Gulf area, Russia, the Caspian Sea basin, Mexico, Venezuela, Angola, and Nigeria. As is implied by the report, the United States must acquire more oil from these countries in order to permit increased oil consumption in the United States at a time of declining domestic production. Even leaving aside the question of whether these countries will be able to boost their production sufficiently to satisfy steadily rising demand in the United States, this strategy poses enormous challenges for the United States because most of these areas are highly unstable and house anti-American governments and forces. It is likely, then, that U.S. efforts to acquire more oil from these countries will entail the increased presence of U.S. military forces in the area and periodic U.S. military intervention. Indeed, the requirement for increased military action in support of U.S. foreign

    Full Text Available Tras los atentados terroristas del 11S de 2001, los Estados Unidos implantaron una política de nuevo imperialismo y de construcción de un nuevo tipo de imperio mundial. Las políticas globales norteamericanas pueden dividirse en economista, cooperativista y reglada por el idealismo Wilsoneano, y el imperialismo Rooseveltiano, basado en un nacionalismo agresivo, militarismo, unilateralismo y governanza global  basada en reglas directas, presencia física y coerción. Las políticas de la administraciones Bush representan esta última vertiente y la Guerra contra el Terror puede ser interpretada como una Primera Guerra Mundial y una guerra civil en los Estados Unidos. Se proclama que un nuevo imperialismo fracasará debido a diversas razones de tipo económica, política, étnica e histórica, y que esta política está debilitando la posición global de Estados Unidos. Al final, se explica cómo en el contexto de una Nueva Contención Pacífica, los ciudadanos norteamericanos y los ciudadanos del resto del mundo pueden utilizar la democracia en contra del nuevo imperialismo y apoyar un cambio de régimen democrático en Estados Unidos, procediendo a la construcción conjunta de un  mundo democrático y justo.________________ABSTRACT:After the terrorist attacks of S-11-2001 the US engaged in the policies of new imperialism and in the construction of a new kind of world-empire.

  13. Diet of the crayfish Paranephrops zealandicus in bush and pasture streams : insights from stable isotopes and stomach analysis

    International Nuclear Information System (INIS)

    Crayfish (Paranephrops zealandicus White) stomachs from streams in both native bush (mainly tree leaves and dicotyledonous seeds) and exotic pasture settings (mainly grass stems and monocotyledonous seeds) were dominated by allochthonous material. More detritus occurred in stomachs in autumn-winter than in spring-summer, but quantities were similar in crayfish from native bush and pasture streams. The stomachs of larger crayfish contained a significantly greater proportion of detritus than smaller individuals. Aquatic invertebrates were the second most abundant dietary category by volume, with highest values in winter, but there were no significant differences between land uses or crayfish size classes. A wide range of invertebrates was eaten by crayfish, with mayfly nymphs, chironomid larvae, and snails predominating. The latter were numerically more prominent in crayfish from bush than pasture streams. Terrestrial invertebrates were recorded from 4% of stomachs, but there were no significant differences in relation to land use, season, or crayfish size class. Despite aquatic invertebrates making up 13C and perhaps of microfloral origin, seems to be an important energy source for crayfish in both stream types. (author). 52 refs., 5 figs., 2 tabs

    The mixture of grass and bush vegetation that typifies many desert scrublands is a distinctive feature of the northern Chihuahuan Desert, where it represents a change in land cover driven by shrub encroachment. In such environments, the redistribution of nutrients by aeolian transport has been recognized as an important biophysical process, with a role in sustaining shrub presence. Investigation of disturbances in these landscapes (e.g. fire and grazing) will enable better understanding of their dust emission behavior with changing climate, perturbance regime and management scenarios. Here we use a portable wind tunnel to investigate the impact of fire and animals on soil erodibilty and dust emissions from different vegetation types in the Sevilleta Wildlife Refuge, central New Mexico. Plots were selected that were a) predominantly creosote bush or b) predominantly grass covered. Dust emission was measured for these surfaces both before and after a prescribed burn was conducted. The grass plots were also clipped and artificially trampled to simulate grazing. PM10 concentrations and emission rates from the test surfaces are shown for initial blow-off experiments as the wind tunnel flow accelerates to a target velocity, plus the steady state emission flux produced under constant wind flow with an added abrader sand. An adjacent area burned 8 months previously also allowed investigation of the change in erodibility of the soil for a known time after fire. Our preliminary results indicate the extent that dust emission is changed by the introduced disturbances, and their differing effect on creosote bush and grass dominated covers.

    Full Text Available Joan Hoff’s searing critique of American foreign policy from World War I to the War on Terror comes at a time when the Wilsonian legacy is attracting renewed interest. Different historians have chosen to emphasise different aspects of this legacy. Erez Manela has explored how antiimperialist intellectuals in Asia were empowered by the doctrine of self-determination during a global Wilsonian Moment, whereas David Kennedy has portrayed George W. Bush as Woodrow Wilson’s natural successor. Hoff, who has published widely on U.S. foreign relations and the American presidency, admits that a true characterisation of Wilsonian foreign policy is problematic. She resorts to a distinction between ‘good’ and ‘bad’ Wilsonianism: the former entails ‘spreading self-determination and free trade capitalism to the world through collective security arrangements’, while the latter indulges in unilateral interventionism. (10 In practice, this ambiguous inheritance has resulted in a unilateralist foreign policy tempered by occasional cooperation with other states.

  16. Conceptual design of a high-voltage compact bushing for application to future N-NBI systems of fusion reactors

    International Nuclear Information System (INIS)

    Highlights: ► Electron Field Emission occurs between large electrodes under vacuum (100 mA of e− at 450 kV). ► An Helium filling pressure of 30 mPa suppresses electron emission up to 950 kV. ► Electron suppression results from a field induced adsorption process which increases the metal work function. ► This process increases the atom binding energy in the nearby of the micro-tips. ► A new 1 MV Bushing concept based on this process is proposed. - Abstract: The energy of future neutral beam injector (NBI) heating systems of fusion power plants ranges from 1 to 2 MeV. They are based on powerful (several tens of MW) hydrogen negative ion electrostatic accelerators where electrodes are polarized by DC high-voltage. The beam line under vacuum is supplied by HV power supplies via a transmission line pressured under SF6 and a high voltage feedthrough called bushing. The paper presents results obtained over experimental campaigns dedicated to high voltage vacuum insulation for future NBI systems (ITER). It addresses the problematic of the electron field emission and the high voltage breakdown limit under vacuum between large electrode surfaces. The paper highlights the dependence of the electron emission (dark current) with the voltage and the background tank pressure: at low pressure (∼1E−3 Pa in hydrogen), an important dark current of I ∼ 100 mA has been measured at 500 kV, while at higher pressure (∼0.3 Pa in helium), the dark current has been nearly suppressed (less than 3 mA of dark current at 970 kV). The paper shows that a field induced gas adsorption process could occur on the emitting surfaces (cathode), and this process tends to lower the electron field emission current by increasing the work function of the electrode surface. The Fowler–Nordheim law applied to the measured dark current indicates about 70% of work function increase at 0.3 Pa in helium. Finally, a new high-voltage bushing concept relevant to the future NBI systems is

  17. Design status and procurement activities of the High Voltage Deck 1 and Bushing for the ITER Neutral Beam Injector

    International Nuclear Information System (INIS)

    Highlights: ► ITER Neutral Beam Injector includes several non-standard components. ► The design status of the −1 MVdc HVD1 and Bushing is described. ► The paper reports also on the integrated layout of the two components. ► Preliminary electrostatic and thermal analyses are presented. ► Procurement activities are outlined. -- Abstract: The ITER Neutral Beam Injector (NBI) power supply system includes several non-standard components, whose ratings go beyond the present industrial practice. Two of these items, to be procured by Fusion for Energy, are: 1.A −1 MVdc air-insulated Faraday cage, called High Voltage Deck 1 (HVD1), hosting the Ion Source and Extractor Power Supplies (ISEPS) and the associated diagnostics. 2.A −1 MVdc feedthrough, called HVD1-TL Bushing, aimed at connecting the HVD1 to the gas (SF6) insulated Transmission Line (TL), containing inside its High Voltage (HV) conductor all ISEPS power and control cables coming from the HVD1 to be connected to the NBI Ion Source services. The paper deals with the status of the design of the HVD1 and HVD1-TL Bushing, focusing on insulation, mechanical and thermal issues as well as on their integration with the other components of the power supply system. In particular, the insulation issue of the integrated system has been addressed by means of an electrostatic Finite Element (FE) analysis whilst a FE thermal simulation has been carried out to assess the impact of the dissipation of the proposed design of the inner conductors (ISEPS conductors) not actively cooled. Finally, the paper describes the status of procurement strategy and execution

    AlSn8Pb2Si2.5Cu0.8Cr0.2 (ASP) is a new bush material with high performance, but its bad plasticity limits its application. By studying the effect of silicon content on the performance of this bush material, it was found that the alloy performance and the distribution of tin and lead were affected by the silicon content. When the silicon content was 2.5%,most of the silicon precipitated along the grain boundary, and most of the lead and tin located along the grain boundary continuously, this resulted in the decrease of the bush material's performance. When the silicon content decreased to 1.0%,it distributed more uniformly, the tin and lead phases were spheroidized and became discontinuous, the performance of ASP material was then greatly increased.

    In order to analyze the cracking and aging reason of the silicone rubber current transformer (CT) insulation bushing used for 8 years from a 500 kV alternating current substation, characteristics including Fourier transform infrared (FTIR) spectroscopy, mechanical properties analysis, hardness, and thermo gravimetric analysis have been carried out. The FTIR results indicated that the external surface of the silicone rubber CT insulation bushing suffered from more serious aging than the internal part, fracture of side chain Si-C bond was much more than the backbone. Mechanical properties and thermal stability results illustrated that the main aging reasons were the breakage of side chain Si-C bond and the excessive cross-linking reaction of the backbone. This study can provide valuable basis for evaluating degradation mechanism and aging state of the silicone rubber insulation bushing in electric power field. PMID:27390631

  7. Prevention of Carbody Vibration of Railway Vehicles Induced by Imbalanced Wheelsets with Displacement-Dependent Rubber Bush

    Tomioka, Takahiro; Takigami, Tadao; Fukuyama, Atsushi; Suzuki, Takashi

    This paper discusses the issue of carbody excitation of railway vehicles due to rotation of imbalanced wheelsets and proposes a simple and cost-effective countermeasure. The basic mechanisms of the carbody excitation are first described, then a displacement-dependent rubber bush, which is used for the connection between bogie frame and carbody, is proposed. The displacement-dependent property is realized by introducing a small gap between the rubber and the inner fixture, and the transmission of excitation force with high-frequency and small displacement are isolated by the gap. The small gap can be created naturally just by skipping the bonding process of rubber and inner fixture, so it is very simple and cost-effective countermeasure against this issue. The stiffness property can be tailored to meet the requirements from motional properties of the bogie by applying a Finite Element Analysis (FEA). The effectiveness and validity of the displacement-dependent rubber bushes applied for traction links are investigated and confirmed by both numerical calculation and excitation test using a full-scale test vehicle in the rolling stock testing plant.

    A sociophysical model for opinion dynamics is shown to embody a series of recent western hung national votes all set at the unexpected and very improbable edge of a fifty-fifty score. It started with the Bush-Gore 2000 American presidential election, followed by the 2002 Stoiber-Schr\\H{o}der, then the 2005 Schr\\H{o}der-Merkel German elections, and finally the 2006 Prodi-Berlusconi Italian elections. In each case, the country was facing drastic choices, the running competing parties were advocating very different programs and millions of voters were involved. Moreover, polls were given a substantial margin for the predicted winner. While all these events were perceived as accidental and isolated, our model suggests that indeed they are deterministic and obey to one single universal phenomena associated to the effect of contrarian behavior on the dynamics of opinion forming. The not hung Bush-Kerry 2005 presidential election is shown to belong to the same universal frame. To conclude, the existence of contraria...

    Creosote bush, Larrea tridentata (Sesse y Moc. Ex DC, Zygophyllaceae) is a shrub found in the deserts of Northern Mexico and Southwestern United States. In traditional medicine, it is used to treat a variety of illnesses including type 2 diabetes. The present study aims to investigate the effects of creosote bush ethanolic extract on plasma and liver parameters associated with the metabolic syndrome in hamsters fed a high fat and cholesterol diet (HFD), comparing them with those induced by ezetimibe (EZ). Seven groups of six hamsters each were formed. Six groups were fed HFD for 2 weeks. The following 2 weeks, the HFD groups received: (1) only HFD, (2) HFD + 3 mg% EZ, (3) HFD + 0.2% creosote bush ethanolic extract, (4) only standard diet (Std Diet), (5) Std Diet + 3 mg% EZ, (6) Std Diet + 0.2% creosote bush ethanolic extract. The beneficial effects of creosote bush ethanolic extract in the HFD hamster model were a reduction of insulin resistance, associated with lower serum insulin and leptin, lower hepatic lipid peroxidation and higher liver antioxidant capacity. Plasma and liver lipids tended or were reduced to values closer to those of animals fed standard diet. A similar effect on lipids was induced by EZ, although with even lower hepatic cholesterol and total lipids concentrations. In general, the change from HFD to standard diet plus ethanolic extract induced the same but deeper changes, including a reduction in plasma glucose and an increase in the percentage of HDL cholesterol. Unlike creosote bush extract, EZ increased food consumption and neutral fecal steroids, with no significant effect on body weight, epididymal fat pads, liver peroxidation or antioxidant capacity. Also EZ did not modify serum insulin and leptin. However, insulin sensitivity improved to values similar to those induced by the extract. This suggests that the mechanism of action of creosote bush ethanolic extract is different to inhibition of cholesterol absorption or increase excretion

Its objective is the comparison of the use of PMC services by the administrations of President George W. Bush and President Barack Obama, respectively. It specifically focuses on the following four areas: capacity (numbers of PMCs deployed and the number of their employees, funding (costs of PMC services, regulation (its forms and laws covering PMCs, control and monitoring (supervision of PMCs and their staff by relevant public bodies. The main finding is that there have been few major changes in the use of PMCs’ services, which contradicts president Obama‘s rhetoric both before and after he assumed office.

    Background: Soft song is a low-amplitude song produced by many birds. Recent studies have confirmed that soft song is an aggressive signal. For example, the Brownish-flanked Bush Warblers Cettia fortipes use soft song in male-male conflicts, particularly prior to attacks. Although stable signaling systems require that signals be honest on average,models predict that cheating is an acceptable strategy for some individuals or in some contexts.Methods: This study aimed to test the reliability of soft song as an aggressive signal in the brownish-flanked bush warbler. We used mounted specimens accompanied by broadcast songs or soft songs to simulate a male attempting to invade an existing territory.Results: We found the mounted specimen that coupled playback of soft songs suffered more and quicker attacks from the territory owner and that the relationship between soft song and subsequent attack in the territory owner was far from perfect. We observed territory owners that both over-signaled(i.e., produced soft song but did not attack) and under-signaled(i.e., attacked without producing soft song). Under-signaling territory owners were relatively more commonly than were over-signaling territory owners, particularly in simulated intrusion that coupled playback of soft song with a mount specimen.Conclusions: We discuss the cost of producing soft song and the potential benefit of the unreliable use of soft song and propose a new hypothesis for under-signaling with soft song; i.e., under-signaling territory owners might benefit from taking the initiative in fights.

    Changes in some lexical features of language have been associated with the onset and progression of Alzheimer's disease. Here we describe a method to extract key features from discourse transcripts, which we evaluated on non-scripted news conferences from President Ronald Reagan, who was diagnosed with Alzheimer's disease in 1994, and President George Herbert Walker Bush, who has no known diagnosis of Alzheimer's disease. Key word counts previously associated with cognitive decline in Alzheimer's disease were extracted and regression analyses were conducted. President Reagan showed a significant reduction in the number of unique words over time and a significant increase in conversational fillers and non-specific nouns over time. There was no significant trend in these features for President Bush. PMID:25633673

    Full Text Available In this article I analyse the Supreme Court’s landmark ruling in Boumediene v. Bush against the background of the discussion concerning the extraterritorial scope of the U.S. Constitution. The long-standing discussion about the scope of constitutional rights is situated within the theoretical framework elaborated by Gerald Neuman who distinguishes between membership models, universalism, ‘global due process’ and the model of ‘mutual obligations’. The last model, which is based on a limited government perspective tends towards the ideal of judicial cosmopolitanism. I argue that Justice Kennedy’s opinion for the Court does not live up to the cosmopolitan ideal of the model of mutual obligations as it was elaborated in Justice Brennan’s dissent in Verdugo and that Kennedy’s casuistic and flexible approach lends itself to possible manipulation. I argue that this danger can be reduced by adopting the minimum standards of international law as a second order framework for constitutional interpretation and I show that the ethical nexus between effective control and responsibility is common to the normative model of mutual obligations, on the one hand, and to the framework adopted in European human rights law and international humanitarian law, on the other.

    Cloud forests are distributed in the Neotropics, from northern Mexico to Argentina, under very specific ecological conditions, namely slopes with high humidity input from clouds and mist. Its distribution in Mesoamerica is highly fragmented, similar to an archipelago, and taxa are thus frequently represented as sets of isolated populations, each restricted to particular mountain ranges and often showing a high degree of divergence, both morphologically and genetically. The common bush-tanager (Chlorospingus ophthalmicus, Aves: Thraupidae) inhabits cloud forests from eastern and southern Mexico south to northwestern Argentina. Here we use 676bp of mtDNA (around the ATPase 8 gene) to explore the genetic variation and phylogeographic structure of the Mexican populations of C. ophthalmicus. Phylogenetic analyses of mtDNA sequences indicate deep genetic structure. Five major clades, which segregate according to geographic breaks, are identified (starting from the deepest one in the phylogeny): (1) Southern Chiapas and Northern Central America, (2) Tuxtlas massif, (3) Sierra Madre del Sur, (4) Eastern Oaxaca and Northern Chiapas, and (5) Sierra Madre Oriental. The long history of isolation undergone by each clade, as suggested by the phylogeny, implies that the species status of each of them should be revised. PMID:15324847

    Full Text Available This study analyzed the water use of the Salix psammophila bush in a semi-arid area in northwest China using a Hydrus-1D model. The model incorporated the effect of thermally driven water flow coupling liquid water, water vapor and heat transport. The model was calibrated and validated using hourly field measurements of soil water content and temperature at different depths for a growing season of 154 days. Furthermore, another Hydrus-1D model was established to simulate environments with decreased heat, rainfall or temperature and an increased leaf area index using calibrated and validated parameters. Our results show that upward and downward thermally driven water vapor fluxes account for 0.11% and 0.28%, respectively, of the corresponding direction of total water flux during the bush’s growing season. Although the vapor flux is very small, simulations incorporating heat flow revealed alterations in the temperature and pressure head gradients over the root zone, especially during dry periods. Consequently, the cumulative contributions of groundwater to evapotranspiration (ETg with heat flow and without heat flow were 26.9% and 40.6%, respectively, during the simulation period. Therefore, the cumulative contribution of groundwater to ETg is overestimated when heat flow is excluded. Thus, we recommended that heat transport be incorporated when evaluating ETg in arid and semi-arid areas.

  10. The improvement of Phaseolus vulgaris as a grain legume crop in Malaysia: Induction of an erect bush type

    International Nuclear Information System (INIS)

    A programme to improve on an introduced variety of dry bean was started in 1980. The variety is an indeterminate climber and the aim is to produce an erect bush type using the technique of mutation induction by gamma rays from a 60Co source. From the results of preliminary studies carried out under greenhouse and field conditions, a procedure for handling the M1 and M2 generations has been developed. A total of 2,264 cell initials irradiated with 30 Krads has been screened. A number of possible mutants have been selected from the single seed bulk (Bsub(s)) and the single pod bulk (Bsub(p)) of the M2 generation. These mutants are being tested in the field as progeny rows of the M3 generation. In addition, the paper discusses plant architecture, the current knowledge of the genetics of the characters which contribute to the architecture of the plant, its relationship to yield and breeding, and the breeding strategies that should be adopted in this programme.

    The Malaconotidea (e.g., butcherbirds, bush-shrikes, batises, vangas) represent an Old World assemblage of corvoid passerines that encompass many different foraging techniques (e.g., typical flycatchers, flycatcher-shrikes, canopy creepers, undergrowth skulkers). At present, relationships among the primary Malaconotidea clades are poorly resolved, a result that could either be attributed to a rapid accumulation of lineages over a short period of time (hard polytomy) or to an insufficient amount of data having been brought to bear on the problem (soft polytomy). Our objective was to resolve the phylogenetic relationships and biogeographic history of the Malaconotidea using DNA sequences gathered from 10 loci with different evolutionary properties. Given the range of substitution rates of molecular markers we sequenced (mitochondrial, sex-linked, autosomal), we also sought to explore the effect of altering the branch-length prior in Bayesian tree estimation analyses. We found that changing the branch-length priors had no major effect on topology, but clearly improved mixing of the chains for some loci. Our phylogenetic analyses clarified the relationships of several genera (e.g., Pityriasis, Machaerirhynchus) and provide for the first time strong support for a sister-group relationship between core platysteirids and core vangids. Our biogeographic reconstruction somewhat unexpectedly suggests that the large African radiation of malaconotids originated after a single over-water dispersal from Australasia around 45-33.7 mya, shedding new light on the origins of the Afrotropical avifauna.

    Full Text Available L’offensive contre l’affirmative action engagée depuis les années 1980 s’est accrue pendant les deux mandats de la présidence Bush, et l’opinion publique s’est radicalisée, percevant désormais de plus en plus fréquemment ces programmes comme une série d’avantages indûment octroyés à un certain nombre de « privilégiés ». Tout programme d’affirmative action doit désormais être étayé par des disparity studies démontrant la réalité de la discrimination, et seules des mesures très ciblées (narrowly tailored sont autorisées pour y remédier. La charge de la preuve a été en quelque sorte inversée. Mais contrairement aux idées reçues, l’affirmative action n’est pas sur le point de disparaître aux États-Unis et malgré son hostilité de principe, le gouvernement Bush n’a pris aucune mesure concrète pour démanteler ces programmes. L’affirmative action connaît aujourd’hui plusieurs transformations majeures, l’évolution la plus marquante étant l’effacement du critère ethno-racial au profit de critères plus neutres et moins idéologiquement polarisants, essentiellement d’ordre géographique et territorial. Dans l’enseignement supérieur par exemple, des procédures d’admission codées ont vu le jour pour favoriser l’accès des minorités ethniques sous-représentées aux campus d’élite, et diverses stratégies de contournement ont été mises en place dans l’adjudication des marchés publics. Ces transformations sont également intéressantes à analyser d’un point de vue transnational, puisque l’on observe une convergence croissante avec le modèle français de discrimination positive, lui aussi fondé sur le camouflage et l’euphémisation de l’identité ethno-raciale et sur une logique de territoire.This article examines the fate of affirmative action in the United States during the eight years of the Bush administration.

While the Bush administration had initially advocated a strategy of “congagement” (containment/ engagement and had defined China as a “strategic competitor”, not only did 9/11 change Washington’s immediate priorities, but, with the US-China economic interdependency, the only realistic strategy between Washington and Beijing seemed to consist in “economic deterrence.”

    Two primary patterns of body size variation have been recorded in ectotherms in relation to latitudinal/altitudinal shifts. In some, body size increases with increasing latitude/altitude whereas, in others, body size decreases with increasing latitude/altitude. This clinal variation is generally assumed to be caused by local adaptation to environmental conditions however the selective variable(s) (temperature, humidity, diet quality, etc.) is still heavily debated. Here we investigate geographic variation in body size of dark and pale color morphs of males of the bush-cricket Isophya rizeensis collected from 15 locations along an elevation gradient ranging from 350 to 2 500 m. Using an information theoretical approach we evaluate the relative support of four different hypotheses (the temperature size rule, the moisture gradient hypothesis, the seasonal constraint hypothesis, and the primary productivity hypothesis) explaining body size variation along the altitudinal gradient. Body size variation in pale color morphs showed a curvilinear relationship with altitude while dark color morphs showed no variation in body size. Body size variation in pale color morphs was highly correlated with precipitation and temperature seasonality values thus giving strong support for the moisture gradient and seasonal constraint hypothesis. Our results reinforce the importance of gradients in humidity and seasonality over temperature in the creation of altitudinal body size clines and the role of selection for resistance to stress factors in the establishment of these clines. Whether a body size cline is observed or not might also depend on the phenotypic properties of the individuals, like coloration. PMID:23956203

    Four newly designed flux meters called the MOSQUITO (Multiple Orifice Sampler and Quantitative Injection Tracer Observer), capable of measuring fluid flow rates and sampling pore fluid chemistry simultaneously, and two temperature loggers were deployed for 430 days adjacent to the Bush Hill hydrate mound in the northern Gulf of Mexico (GC 185). The main objective of the deployment was to understand how chemistry, temperature, and subsurface hydrology dynamically influence the growth and dissociation of the gas hydrate mound. The flux meters were deployed in a mussel field, in bacterial mats, in a tubeworm field, and at a background site approximately 100 m southwest of the hydrate mound. Results from the longterm chemical monitoring suggest that this system is not in dynamic equilibrium. Gas hydrate actively formed within the mussel field adjacent to the most active gas vent, in the tubeworm field, and at the background site. The hydrology is variable with upward flow rates ranging from 1-90 cm/yr and downward flow rates from 3-130 cm/yr. Two distinct hydrologic pulsing events were sampled across the three mound sites, which advect a fluid from depth that further stabilizes the gas hydrate deposit. The hydrogeochemistry at Bush Hill seems to be influenced by multiple mechanisms such as active formation of gas hydrate, fluid influx and outflux due to active venting of CH4 at transient methane seeps at and near the mound, local salt tectonics, and density driven convection. The fluxes of fluid, solutes, and methane may have a significant impact on the seafloor biochemical environment and the water column chemistry at Bush Hill. (Author)

    Full Text Available Abstract Background Little is known about the use of bush medicine and traditional healing among Aboriginal Australians for their treatment of cancer and the meanings attached to it. A qualitative study that explored Aboriginal Australians' perspectives and experiences of cancer and cancer services in Western Australia provided an opportunity to analyse the contemporary meanings attached and use of bush medicine by Aboriginal people with cancer in Western Australia Methods Data collection occurred in Perth, both rural and remote areas and included individual in-depth interviews, observations and field notes. Of the thirty-seven interviews with Aboriginal cancer patients, family members of people who died from cancer and some Aboriginal health care providers, 11 participants whose responses included substantial mention on the issue of bush medicine and traditional healing were selected for the analysis for this paper. Results The study findings have shown that as part of their healing some Aboriginal Australians use traditional medicine for treating their cancer. Such healing processes and medicines were preferred by some because it helped reconnect them with their heritage, land, culture and the spirits of their ancestors, bringing peace of mind during their illness. Spiritual beliefs and holistic health approaches and practices play an important role in the treatment choices for some patients. Conclusions Service providers need to acknowledge and understand the existence of Aboriginal knowledge (epistemology and accept that traditional healing can be an important addition to an Aboriginal person's healing complementing Western medical treatment regimes. Allowing and supporting traditional approaches to treatment reflects a commitment by modern medical services to adopting an Aboriginal-friendly approach that is not only culturally appropriate but assists with the cultural security of the service.

Species distribution models can offer a solution to this dilemma by analysing the species-environment relationship with help of Geographic information systems (GIS. In this study, we model the distribution of the non-native bush-cricket Metrioptera roeselii in the agricultural landscape in mid-Sweden where the species has been rapidly expanding in its range since the 1990s. We extract ecologically relevant landscape variables from Swedish CORINE land-cover maps and use species presence-absence data from large-scale surveys to construct a species distribution model (SDM. The aim of the study is to increase the knowledge of the species range expansion pattern by examining how its distribution is affected by landscape composition and structure, and to evaluate SDM performance at two different spatial scales. We found that models including data on a scale of 1 × 1 km were able to explain more of the variation in species distribution than those on the local scale (10 m buffer on each side of surveyed road. The amount of grassland in the landscape, estimated from the area of arable land, pasture and rural settlements, was a good predictor of the presence of the species on both scales. The measurements of landscape structure – linear elements and fragmentation - gave ambivalent results which differed from previous small scaled studies on species dispersal behaviour and occupancy patterns. The models had good predictive ability and showed that areas dominated by agricultural fields and their associated grassland edges have a high probability being colonised by the species. Our study identified important landscape variables that explain the distribution of M. roeselii in Mid-Sweden that may also

  2. Final configuration with assembly assessment of the 100 kV high voltage bushing for the Indian test facility

    International Nuclear Information System (INIS)

    The Indian Test Facility (INTF) of Neutral Beam (NB) system is an Indian voluntary effort for the full characterization of the diagnostic neutral beam which is the part of ITER's neutral beam system. The design activities of INTF NB system are completed. The INTF High Voltage Bushing (HVB), which is one of the component of NB system, is designed to connect all the required feedlines, e.g. electrical busbars, RF co-axial lines, diagnostic lines and hydraulic and gas feed lines, carried by the transmission line from the HV deck to the Beam Source of NB system. It forms the primary vacuum boundary and provides 100 kV isolation for INTF beam operation. The entire feedlines pass through a metallic plate of HVB called Dished Head (DH) where all the feedlines converge. The overall diameter of DH is 847 mm which is governed by the diameter of the Porcelain insulator which is meant for 100 kV isolation. The effective diameter where all the feedlines converge at the dished head is ∼ 600 mm which is quite a challenge to accommodate 26 feedlines each of average diameter 60 mm. Electrical feedlines require Vacuum-Electrical feedthroughs for voltage isolation whereas water and gas lines are considered to be directly welded with the DH except one water line which requires 12 kV voltage isolation with respect to DH. For RF lines, different scheme is considered which includes separate Electrical Feedthrough and Vacuum Barrier. To provide connection to electrical cables of heaters and thermocouples, 4 numbers of multipin vacuum compatible electrical feedthroughs are provided which can accommodate ∼250 cables. Due to space constraints, Vacuum-Electrical Feedthroughs are considered to be welded with the DH and therefore they shall be of metal-ceramic-metal configuration to allow welding. To avoid undue loading on the ceramic part, the feedlines are supported additionally at DH using vacuum compatible and electrically insulating material. One more important aspect of the INTF

Notre étude vise à évaluer l’impact du libre-échange sur les exportations canadiennes vers les États-Unis et en particulier l’impact des mesures prises sous la présidence Bush. Nous commençons par un survol de l’évolution des flux de commerce entre le Canada et ses partenaires nord-américains. La deuxième section porte sur la mise en place de l’Accord de libre-échange canado-américain (ALE et de l’Accord de libre-échange nord-américain (ALENA. La troisième section traite de la plus récente période, qui s’amorce au lendemain des attentats terroristes du 11 septembre 2001. Nous évaluons les effets des politiques américaines de sécurité adoptées suite à ces événements, qui ont semblé reléguer le partenariat économique de la région au second plan. La dernière section présente les résultats de notre modélisation économétrique des impacts des accords de libre-échange et du resserrement des politiques de sécurité à la frontière sur les exportations canadiennes vers les États-Unis. Dans l’ensemble, nous observons que l’ALENA a eu un impact positif important sur les exportations canadiennes et que cet impact bénéfique s’est maintenu pendant les années Bush. Toutefois, le resserrement des contrôles à la frontière des États-Unis a représenté l’équivalent d’un tarif sur les exportations vers ce pays et un fardeau non négligeable pour les entreprises canadiennes.Viewed from Canada, which conducts 70-80 percent of its foreign trade with the United States, the evolution of commercial flows is a major component in assessing the George W.

    The effects of foliar applications of ethylenediurea (EDU) on responses to ozone by field-grown bush bean (Phaseolus vulgaris L.) lines 'S156' (O{sub 3}-sensitive) and 'R123' (O{sub 3}-tolerant), and cultivars 'BBL 290' (O{sub 3}-sensitive) and 'BBL 274' (O{sub 3}-tolerant) were investigated during the 2001 and 2002 growing seasons. EDU was applied weekly to designated plants between primary leaf expansion and pod senescence. Results were compared with control plants at harvests made at pod maturation and pod senescence. In 2001, average hourly ambient O{sub 3} concentrations ranged between 41 and 59 ppb for a total of 303 h; in 2002, for 355 h. EDU applications prior to pod maturation significantly increased the number of marketable pods in 'R123', but not for the other cultivars. Harvests at pod senescence showed significant improvements in crop yield production in EDU-treated 'S156' plants, whereas for EDU-treated 'R123' plants significant reductions were determined in above-ground biomass and seed production. In contrast, results from 'BBL 290' and 'BBL 274' at both harvest points were inconclusive. Growth and reproductive responses of O{sub 3}-sensitive and O{sub 3}-tolerant bush bean plants to EDU applications varied, depending on developmental stages, duration of EDU applications, and fluctuations in ambient O{sub 3}. - Plant sensitivity to ozone, stage of plant development, number of applications of EDU and ambient ozone affect bean plant responses to EDU.

    Full Text Available Alors que l’élection de George B. Bush à la présidence des États-Unis avait pu autoriser certains à nourrir l’espoir d’une relance du processus d’intégration économique entre l’Amérique latine et l’Amérique du Nord, le bilan de ces huit années est mitigé et bien des incertitudes pesaient sur l’avenir de ce processus au moment de l’entrée en fonction de Barack Obama. Pour éclairer cette évolution, l’article replace les années Bush dans le contexte du recentrage sur la dimension économique de la relation qui fut consécutif à la fin de la guerre froide. La première partie, fondée sur l’étude des données chiffrées disponibles concernant les échanges commerciaux et des mouvements de capitaux, met en évidence une progression en trompe l’œil de ces flux, suggérant un désintérêt relatif des États-Unis pour leur traditionnelle arrière-cour. Pour rendre compte de cette nouvelle donne, la seconde partie revient sur le cadre géopolitique et géoéconomique dans laquelle s’inscrit la relation à partir de 2001.While George W. Bush’s election had promised to revive the drive towards further economic integration in the Americas, as he was leaving office eight years later the achievements of his presidency seemed rather mixed and the future of U.S.-Latin America relations uncertain. To shed light on this turnaround, this paper sets the Bush years in the wider context of post-Cold War renewed U.S. emphasis on the economic dimension of its relationship to Latin America. The first part, which focuses on quantitative data, concludes that although two-way trade and capital flows did grow significantly between 2000 and 2007, the momentum of the 1990s was largely lost. In an attempt to account for this trend, the second part focuses on the geopolitical and geoeconomic background which led to the United States’ relations with Latin America taking a new direction after 2001.

    Full Text Available Nordihydroguaiaretic acid (NDGA is a phenolic antioxidant found in the leaves and twigs of the evergreen desert shrub, Larrea tridentata (Sesse and Moc. ex DC Coville (creosote bush. It has a long history of traditional medicinal use by the Native Americans and Mexicans. The modulatory effects of topically applied NDGA was studied on acute inflammatory and oxidative stress responses in mouse skin induced by stage I tumor promoting agent, 12-O-tetradecanoylphorbol-13-acetate (TPA. Double TPA treatment adversely altered many of the marker responses of stage I skin tumor promotion cascade. Pretreatment of NDGA in TPA-treated mice mitigated cutaneous lipid peroxidation and inhibited production of hydrogen peroxide. NDGA treatment also restored reduced glutathione level and activities of antioxidant enzymes. Elevated activities of myeloperoxidase, xanthine oxidase and skin edema formation in TPA-treated mice were also lowered by NDGA indicating a restrained inflammatory response. Furthermore, results of histological study demonstrated inhibitory effect of NDGA on cellular inflammatory responses. This study provides a direct evidence of antioxidative and anti-inflammatory properties of NDGA against TPA-induced cutaneous inflammation and oxidative stress corroborating its chemopreventive potential against skin cancer.

    By integrating mitochondrial DNA (mtDNA), microsatellites and ecological niche modelling (ENM), we investigated the phylogeography of Mexican populations of the common bush-tanager Chlorospingus ophthalmicus to examine the relative role of geographical and ecological features, as well as Pleistocene climatic oscillations in driving the diversification. We sequenced mtDNA of individuals collected throughout the species range in Mexico and genotyped them at seven microsatellite loci. Phylogeographic, population genetics and coalescent methods were used to assess patterns of genetic structure, gene flow and demographic history. ENM was used to infer contractions and expansions at different time periods as well as differences in climatic conditions among lineages. The retrieved mitochondrial and microsatellite groups correspond with the fragmented cloud forest distribution in mountain ranges and morphotectonic provinces. Differing climatic conditions between mountain ranges were detected, and palaeodistribution modelling as well as demographic history analyses, indicated recent population expansions throughout the Sierra Madre Oriental (SMO). The marked genetic structure of C. ophthalmicus was promoted by the presence of ecological and geographical barriers that restricted the movement of individuals among mountain ranges. The SMO was mainly affected by Pleistocene climatic oscillations, with the moist forests model best fitting the displayed genetic patterns of populations in this mountain range. PMID:26988412

  17. The use of language and its impact on energy policy discourse: A case study of the hydrogen economy and the news media during the G.W. Bush administration

    Science.gov (United States)

    Waegel, Alexander Francis

    The development of policy is subject to many different influences. The subjects are often complex and citizens must rely on information provided by third parties in order to participate in the discussion. The news media has traditionally been the primary provider of such information and are counted upon to publish unbiased accounts of events. However, the news media gets information from its own sources and this offers an opportunity for powerful, well-organized groups to influence the presentation of these topics. This is done through the creation and dissemination of constructed narratives, which remove the contexts from facts to present different conclusions (Barthes, 1957). Sourcing discusses how the news media may be influenced by powerful organizations providing free, easily published material (Herman, 1988). The 24 hour news cycle, the demand for ratings, and the impossibility of funding independent research journalism for every topic requires them to seek information from sources viewed as reliable and authoritative, such as the government or major corporations. The wealthier and more powerful organizations are better able to provide this large quantity of information in a readily publishable format and thus have the potential to influence the presentation to reflect positively on their positions. As a technologically and politically complex subject, energy policy would be particularly prone to the influence of sourcing. Hydrogen energy was used as a case study to search for the presence of sourcing. Hydrogen fuels cells offer potential for the reduction of greenhouse gasses and other benefits, but have significant disadvantages as well. While the academic community remained divided on the technology, the G.W. Bush administration offered it unwavering support. The Bush administration and the academic community both released a great deal of information about hydrogen but each set presented a very different outlook.

  18. Effects of solar UV-B radiation on growth, flowering and yield of central and southern European bush bean cultivars (Phaseolus vulgaris L.)

    International Nuclear Information System (INIS)

    Different cultivars of bush beans (Phaseolus vulgaris L.) originating from Central and Southern Europe were grown from July to August/September 1993 up to 7 and 8 weeks, respectively, in two greenhouses covered by different UV-B-absorbing (280-320nm) plastic foils. By using the ambient UV-B radiation of the southern location (Portugal, 38.7°N, 9.1°W) in one of the greenhouses as intense UV-B radiation compared to the reduced radiation in the second greenhouse at the same place, a difference in UV-B of about 8–10% was simulated. All cultivars examined showed significant reductions in height of up to 31,8% in most growth phases under intense UV-B. Also fresh and dry weight as well as leaf area were reduced under intense UV-B in the cultivars Purple Teepee, Cropper Teepee and Goldstrahl, and in early growth phases also in Coco bianco, but with ongoing development this cultivar caught up. Cultivars Hilds Maja, Primel, Manata and Cannellino exhibited no UV-B effects on weight and leaf area. A flowering delay of up to 1 day was observed under intense UV-B in several cultivars. Probably due to this delay the yield (fresh weight of fruits) decreased in all cultivars up to 55% under intense UV-B at harvest time, while the potential yield (sum of buds, opened flowers and fruits) was reduced only in the cultivars Cropper Teepee, Purple Teepee, Cannellino and Goldstrahl. The UV-sensitivity index (UVSI) calculated according to the UV induced changes in growth, dry weight and yield at the second harvest date has shown that all cultivars are UV-sensitive, however the index was numerically higher for Southern European cultivars (average = 2.5) than for Central European ones (average = 2.3) which means that the first group was slightly less UV-sensitive than the second.

    Responses of bush bean (Phaseolus vulgaris L.) lines 'S156' (O{sub 3}-sensitive) and 'R123' (O{sub 3}-tolerant), and cultivars 'BBL 290' (O{sub 3}-sensitive) and 'BBL 274' (O{sub 3}-tolerant) to ambient ozone (O{sub 3}) were investigated during the 2001 and 2002 growing seasons. Seedlings were grown in pots inside open-top chambers (OTCs), with charcoal filtered (CF) and non-filtered (NF) ambient air, and in non-chambered ambient air (AA) plots. Growth parameters from individual plants were evaluated after harvests at the end of vegetative (V{sub 4}) and reproductive (R{sub 10}) growth phases. Results at V{sub 4} indicated that CF did not provide additional benefits over NF in 'S156' in 2001 and 2002. In contrast, exposure to CF significantly impaired the growth of 'R123'. At the end of R{sub 10}, 'S156' produced more pods, most of which remained immature, and contained fewer seeds or were more frequently aborted, whereas pods produced in 'R123' reached pod maturation and senescence more consistently. Despite increased seed weights inside the OTCs, as observed in 'S156', differences between the two lines were insignificant when grown outside OTCs. Results from the 'BBL 290'/'BBL 274' pair, especially at V{sub 4} phase, remained inconclusive. Plant morphological characteristics, variabilities in environmental conditions, and 'chamber effects' inside OTCs were influential in determining plant response to ambient O{sub 3}. - Phenotypic differences, morphological characteristics, and 'chamber effects' inside OTCs are equally influential in determining the responses of beans to O{sub 3}.

    Adults, immatures and eggs of Tuckerella japonica (Ehara) were collected from unknown clones or varieties of Camellia sinensis (L.) O. Kuntze tea bushes in the Clemson University Farm, Coastal Research and Education Center, Charleston, South Carolina; from Assam hybrids in The Caw Caw Nature Preserve in Ravenel, SC; from C. sinensis and C. assamica (Masters) in the Charleston Tea Plantation on Wadmalaw Island, SC; C. sinensis in the Fairhope Tea Plantation in Fairhope, Alabama; and from C. sinensis 'Rosea' and a C. sinensis and C. assamica hybrid in Savannah and Ellabell, Georgia, between 1994 and 2015. This mite was consistently collected from 1-, 2- and 3+-year-old wood of tea plants with significantly greater numbers collected from 2-year-old wood. All stages of the mite were found within longitudinally split areas of the wood where underlying green bark tissues were exposed. As 1-year-old wood matured, there was increased splitting of the bark with increased mite presence. Mature green fruit (= developing seed pods) of tea were also frequented by T. japonica between June-July and October and their numbers were no greater than those on 1- or 3+-year wood. When the fruit were small (March-May) or as they hardened in late fall, they were not suitable feeding sites for this mite. Very few T. japonica were collected from 50 mature, inner or outer leaf samples with none usually found. Tuckerella japonica has multiple, overlapping generations and occurs on tea throughout the year in Alabama, Georgia and South Carolina, USA. PMID:27294360

  1. Acquired changes in stomatal characteristics in response to ozone during plant growth and leaf development of bush beans (Phaseolus vulgaris L.) indicate phenotypic plasticity

    International Nuclear Information System (INIS)

    Bush bean (Phaseolus vulgaris L.) lines 'S156' (O3-sensitive)/'R123' (O3-tolerant) and cultivars 'BBL 290' (O3-sensitive)/'BBL 274' (O3-tolerant) were used to study the effects of O3 on stomatal conductance (g s), density, and aperture size on leaf and pod surfaces with the objective of establishing links between the degree of plant sensitivity to O3 and plasticity of stomatal properties in response to O3. Studies in open-top chambers (OTCs) and in continuously stirred tank reactors (CSTRs) established a clear relationship between plant developmental stages, degrees of O3 sensitivity and g s: while 'S156' had higher g s rates than 'R123' earlier in development, similar differences between 'BBL 290' and 'BBL 274' were observed at later stages. G s rates on the abaxial leaf surfaces of 'S156' and 'BBL 290', accompanied by low leaf temperatures, were significantly higher than their O3-tolerant counterparts. Exposure to O3 in CSTRs had greater and more consistent impacts on both stomatal densities and aperture sizes of O3-sensitive cultivars. Stomatal densities were highest on the abaxial leaf surfaces of 'S156' and 'BBL 290' at higher O3 concentrations (60 ppb), but the largest aperture sizes were recorded on the adaxial leaf surfaces at moderate O3 concentrations (30 ppb). Exposure to O3 eliminated aperture size differences on the adaxial leaf surfaces between sensitive and tolerant cultivars. Regardless of sensitivity to O3 and treatment regimes, the smallest aperture sizes and highest stomatal densities were found on the abaxial leaf surface. Our studies showed that O3 has the potential to affect stomatal plasticity and confirmed the presence of different control mechanisms for stomatal development on each leaf surface. This appeared to be more evident in O3-sensitive cultivars. - O3 has the potential to affect stomatal development and the presence of different control mechanisms on each leaf surface is confirmed

    Bush bean (Phaseolus vulgaris L.) lines 'S156' (O{sub 3}-sensitive)/'R123' (O{sub 3}-tolerant) and cultivars 'BBL 290' (O{sub 3}-sensitive)/'BBL 274' (O{sub 3}-tolerant) were used to study the effects of O{sub 3} on stomatal conductance (g {sub s}), density, and aperture size on leaf and pod surfaces with the objective of establishing links between the degree of plant sensitivity to O{sub 3} and plasticity of stomatal properties in response to O{sub 3}. Studies in open-top chambers (OTCs) and in continuously stirred tank reactors (CSTRs) established a clear relationship between plant developmental stages, degrees of O{sub 3} sensitivity and g {sub s}: while 'S156' had higher g {sub s} rates than 'R123' earlier in development, similar differences between 'BBL 290' and 'BBL 274' were observed at later stages. G {sub s} rates on the abaxial leaf surfaces of 'S156' and 'BBL 290', accompanied by low leaf temperatures, were significantly higher than their O{sub 3}-tolerant counterparts. Exposure to O{sub 3} in CSTRs had greater and more consistent impacts on both stomatal densities and aperture sizes of O{sub 3}-sensitive cultivars. Stomatal densities were highest on the abaxial leaf surfaces of 'S156' and 'BBL 290' at higher O{sub 3} concentrations (60 ppb), but the largest aperture sizes were recorded on the adaxial leaf surfaces at moderate O{sub 3} concentrations (30 ppb). Exposure to O{sub 3} eliminated aperture size differences on the adaxial leaf surfaces between sensitive and tolerant cultivars. Regardless of sensitivity to O{sub 3} and treatment regimes, the smallest aperture sizes and highest stomatal densities were found on the abaxial leaf surface. Our studies showed that O{sub 3} has the potential to affect stomatal plasticity and confirmed the presence of different control mechanisms for stomatal development on each leaf surface. This

    Full Text Available Aboriginal people in Canada experience disproportionately high rates of diet-related illnesses, such as obesity and diabetes. Food insecurity has been identified as a contributing factor to these illnesses along with a loss of traditional lifestyle. Current food systems within northern subarctic and arctic regions of Canada rely heavily on imported foods that are expensive (when available, and are environmentally unsustainable. A warming subarctic and arctic climate present challenges, but also offers the opportunity for local agricultural production that can increase food security and promote a more sustainable food system. In this study the feasibility of sustainably growing potatoes (Solanum tuberosum L. utilizing agroforestry practices to enhance food security in remote subarctic communities is explored through a case study in Fort Albany First Nation in northern Ontario, Canada. Potato crops were grown over a two-year period and rotated into plots that had been planted with green bush beans (Phaseolus vulgaris L.. Results showed that potatoes and bush beans could be grown successfully in the subarctic without the use of greenhouses with yields comparable to more conventional high-input agricultural methods. In subarctic Canada, sustainable local food production can help to promote social capital, healthier lifestyles, and food security.

    Haiyan Zhang

    Full Text Available Nordihydroguaiaretic acid (NDGA, the main metabolite of Creosote bush, has been shown to have profound effects on the core components of the metabolic syndrome (MetS, lowering blood glucose, free fatty acids (FFA and triglyceride (TG levels in several models of dyslipidemia, as well as improving body weight (obesity, insulin resistance, diabetes and hypertension, and ameliorating hepatic steatosis. In the present study, a high-fructose diet (HFrD fed rat model of hypertriglyceridemia was employed to further delineate the underlying mechanism by which NDGA exerts its anti-hypertriglyceridemic action. In the HFrD treatment group, NDGA administration by oral gavage decreased plasma levels of TG, glucose, FFA, and insulin, increased hepatic mitochondrial fatty acid oxidation and attenuated hepatic TG accumulation. qRT-PCR measurements indicated that NDGA treatment increased the mRNA expression of key fatty acid transport (L-FABP, CD36, and fatty acid oxidation (ACOX1, CPT-2, and PPARα transcription factor genes and decreased the gene expression of enzymes involved in lipogenesis (FASN, ACC1, SCD1, L-PK and ChREBP and SREBP-1c transcription factors. Western blot analysis indicated that NDGA administration upregulated hepatic insulin signaling (P-Akt, AMPK activity (P-AMPK, MLYCD, and PPARα protein levels, but decreased SCD1, ACC1 and ACC2 protein content and also inactivated ACC1 activity (increased P-ACC1. These findings suggest that NDGA ameliorates hypertriglyceridemia and hepatic steatosis primarily by interfering with lipogenesis and promoting increased channeling of fatty acids towards their oxidation.

    2013-01-01

      采用尺寸为0.5~4µm 的层片状蛇纹石粉末,通过高能球磨对其进行油基细化、改性和分散,然后添加到基础油(CD 15W/40柴油机润滑油)中制成含油溶性蛇纹石微粉的润滑剂。借助环–块摩擦磨损试验机研究蛇纹石颗粒作为润滑油添加剂对类轴–轴瓦摩擦副表面的自修复效应,并探讨其作用机理。结果表明:在载荷为600 N、蛇纹石颗粒含量(质量分数)为0.5%时,润滑油具有最佳的摩擦学性能及自修复性能,摩擦因数和磨痕宽度分别较基础油润滑时降低约9.7%和40.7%;磨损表面较平整光滑,其上形成厚约0.68µm 的自修复层。修复层主要由铁的多种氧化物、石墨、有机残留物及少量 FeS 组成,具有较高的力学性能;蛇纹石颗粒对摩擦副表面具有精细研磨作用,不仅能降低表面的粗糙度,而且在高压闪温条件下释放更多的活性氧参与摩擦界面的氧化反应,促进保护膜的形成并与石墨及有机残留物产生协同作用,实现摩擦表面的润滑与原位自修复。%The oil-soluble serpentine powders were prepared out of the flaky serpentine powders with particle size of 0.5~4 µm using the integral process of oil-based refinement, modification and dispersion with high-energy ball-milling method. The as-prepared additive was added to the Great Wall CD 15W/40 diesel oil to form various lubricants and their self-restoration effects on the tribosurfaces analogue of shaft-bushing contact were investigated using the ring-on-block friction and wear tester. In addition, the corresponding mechanism was discussed. Results indicate that the oil with 0.5%content of serpentine particles shows most excellent tribological properties and self-restoration performance at 600N. The friction coefficient and width of wear trace decrease by 9.7% and 40.7% relative to those of the base oil, respectively. The worn surface is smooth with a restoration film

    When Richard Nixon became president in 1969, he had laid out a conservative agenda for shaping the federal courts. He criticized the Supreme Court, led by Chief Justice Earl Warren, for its activism on behalf of the rights of criminals and minorities. Nixon wanted the states to decide such matters rather than receive detailed instructions from the unelected Supreme Court. Republican presidents and conservative activists have since followed Nixon's rhetoric and looked for proof of a conse...

    The purpose of this thesis is to examine whether the individual political leader is important for the analysis of international relations. Traditionally the focus of investigation in international relations has been on the nation-state, or the systems level, and as a result the individual level has been somewhat neglected.

  19. Chagas disease: from bush to huts and houses. Is it the case of the Brazilian amazon?

    Directory of Open Access Journals (Sweden)

    José Rodrigues Coura

    1999-09-01

    Full Text Available Two of the major problems facing the Amazon - human migration from the other areas and uncontrolled deforestation - constitute the greatest risk for the establishment of endemic Chagas disease in this part of Brazil. At least 18 species of triatomines had been found in the Brazilian Amazon, 10 of them infected with Trypanosoma cruzi, associated with numerous wild reservoirs. With wide-range deforestation, wild animals will perforce be driven into other areas, with tendency for triatomines to become adapted to alternative food sources in peri and intradomicilies. Serological surveys and cross-sectional studies for Chagas disease, carried out in rural areas of the Rio Negro, in the Brazilian Amazon, showed a high level of seropositivity for T. cruzi antibodies. A strong correlation of seroreactivity with the contact of gatherers of piaçava fibers with wild triatomines could be evidenced.

The degree of inter-patch dispersal, in turn, depends on the dispersal abili...

  9. Environmental impact of almond crop in strong slope with two vegetable covers: bush and leguminous

    International Nuclear Information System (INIS)

    Soil erosion is one of the main physical processes of land degradation in Spain. Several studies in the Mediterranean environment have demonstrated the positive effect of vegetation covers on the reduction of water erosion and their indirect improvement of the soil physical and chemical properties, essentially by the incorporation of organic matter. Sol loss and surface runoff patterns over a four-year period were monitors in erosion plots from hill slope with two different cover-crop strips: (1) non-tillage with leguminous (Lens esculenta Moench) and (2) non-tillage with and a mixture of autochthonous thymes (Thymus baeticus Boiss. ex Lacaita, Thymus capitatus (L) Hoffmanns and Link., Thymus vulgaris L.) of 3 m with, in Lanjaron (Granada) on the south flank of the Sierra Nevada of southeast Spain. The erosion plots were located on the hill slope at 35% incline, at 580 m in altitude and with 144 m2 (24 m x 6 m) in area. the area selected for the experiment is the part of the rainfed orchard given entirely with almond (Prunus amygdalus Basch cv.

    2016-02-01

    Sutherlandia frutescens is a medicinal plant, traditionally used to treat various types of human diseases, including cancer. Previous studies of several botanicals link suppression of prostate cancer growth with inhibition of the Gli/hedgehog (Gli/Hh) signaling pathway. Here we hypothesized the anti-cancer effect of S. frutescens was linked to its inhibition of the Gli/Hh signaling in prostate cancer. We found a dose- and time-dependent growth inhibition in human prostate cancer cells, PC3 and LNCaP, and mouse prostate cancer cell, TRAMP-C2, treated with S. frutescens methanol extract (SLE). We also observed a dose-dependent inhibition of the Gli-reporter activity in Shh Light II and TRAMP-C2QGli cells treated with SLE. In addition, SLE can inhibit Gli/Hh signaling by blocking Gli1 and Ptched1 gene expression in the presence of a Gli/Hh signaling agonist (SAG). A diet supplemented with S. frutescens suppressed the formation of poorly differentiated carcinoma in prostates of TRAMP mice. Finally, we found Sutherlandioside D was the most potent compound in the crude extract that could suppress Gli-reporter in Shh Light II cells. Together, this suggests that the S. frutescens extract may exert anti-cancer effect by targeting Gli/Hh signaling, and Sutherlandioside D is one of the active compounds. PMID:26377232

    2012-12-01

    Full Text Available In most of the literature on the subject, urban and rural areas are presented as real physical entities that are geographically determined. Obviously such an approach is important and necessary, but in this contribution I want to draw attention to ‘the urban’ and ‘the rural’ as ideas, as items of cultural landscape rather than as physical facts. This will result both in a history of ideas and a social history of the war in Angola as experienced by civilians from the south-eastern part of the country. The article is based on a case-study that deals with the history of south-east Angola, an area that was in a state of war from 1966 to 2002. In the course of the 1990s I spoke with immigrants from this region who were resident in Rundu, Northern Namibia, mostly as illegal refugees. In our conversations the immigrants explained how the categories ‘town’ and ‘country’ came into being during colonialism and what changes occurred after the war started. They argued that during the war agriculture in the countryside became well-nigh impossible and an opposition between ‘town’ and ‘bush’ came into being that could have lethal consequences for the civilian population living in the region. This case-study on south-east Angola shows the importance of a historical approach to categories such as ‘urbanity’ and ‘rurality’ as such categories may undergo relatively rapid change – in both discourse and practice.

  7. The impact of an invasive exotic bush on the stopover ecology of migrant passerines

    Directory of Open Access Journals (Sweden)

    Arizaga, J.

    2013-01-01

    Full Text Available Migration is highly energy-demanding and birds often need to accumulate large fuel loads during this period. However, original habitat at stopover sites could be affected by invasive exotic plants outcompeting native vegetation. The impact of exotic plants on the stopover behavior of migrant bird species is poorly understood. As a general hypothesis, it can be supposed that habitat change due to the presence of exotic plants will affect migrants, having a negative impact on bird abundance, on avian community assemblage, and/or on fuel deposition rate. To test these predictions, we used data obtained in August 2011 at a ringing station in a coastal wetland in northern Iberia which contained both unaltered reedbeds (Phragmites spp. and areas where the reedbeds had been largely replaced by the invasive saltbush (Baccharis halimifolia. Passerines associated with reedbeds during the migration period were used as model species, with a particular focus on sedge warblers (Acrocephalus schoenobaenus. The saltbush promoted a noticeable change on bird assemblage, which became enriched by species typical of woodland habitats. Sedge warblers departed with a higher fuel load, showed a higher fuel deposition rate, and stayed for longer in the control zone than in the invaded zone. Invasive plants, such as saltbush, can impose radical changes on habitat, having a direct effect on the stopover strategies of migrants. The substitution of reedbeds by saltbushes in several coastal marshes in Atlantic Europe should be regarded as a problem with potential negative cons equences for the conservation of migrant bird species associated with this habitat.

    Particular aspects provide novel methods for redirecting carbon allocation in plants or cell culture from lignification to inherently more useful and tractable materials, and to facilitate the generation of, e.g., biofuels from the remaining plant ro culture biomass. Particular aspects provided novel methods for converting monolignols into allyl/propenyl phenols, and for chavicol/eugenol formation or production. Additional aspects relate to the discovery of novel chavicol/eugenol synthases that convert p-coumaryl/coniferyl alcohol esters into chavicol/eugenol, and to novel compositions (e.g., novel proteins and nucleic acids encoding same), and novel methods using same for producing or forming chavicol/eugenol and other derivatives in cell culture and/or genetically modified plants, and for re-engineering the composition of plant biomass. Particular aspects provide novel methods for generation in culture or in planta of liquid/combustible allyl/propenyl phenols, and these phenolic products are utilized for (non-ethanol) biofuel/bioenergy purposes, while the remaining plant biomass facilitates the generation of other biofuels.

  14. The single species hypothesis: truly dead and pushing up bushes, or still twitching and ripe for resuscitation?

    Science.gov (United States)

    Hunt, Kevin D

    2003-08-01

    Frank Livingstone proclaims himself to be the last living proponent of the single species hypothesis. In sharp contrast, a species-rich, bushy phylogeny is favored by most human paleontologists. Is Livingstone's proclamation merely contrarian posturing, or does closer inspection warrant reconsideration of just how speciose the hominin lineage is? The high-speciation perspective draws on evidence of speciosity in the Cercopithecoidea and punctuated equilibria theory for support. If blue monkeys and redtail monkeys are indistinguishable skeletally, this reasoning goes, or if red colobus and black and white colobus are likewise indistinguishable, should we not expect that there are more species of hominin than is apparent from skeletal evidence alone? A contrarian perspective notes that not all monkey taxa are speciose. Importantly, two broadly distributed, partly terrestrial monkeys have not speciated at all: vervets and baboons. Nor are monkeys the first choice as a hominin speciation model. If expectations of species numbers are based on the Hominoidea, a taxon more closely related to hominins, more similar in body size, and found in more hominin-like habitats than monkeys, a single-species perspective is more appealing. No great ape genus has even two sympatric species. Moreover, despite a separation of 1.6 Ma, West African chimpanzees have not speciated from Pt. troglodytes nor Pt. schweinfurthii. It is notable that no two contemporaneous species of hominin were separated by significantly more than this interval. A biological--as opposed to an ecological or geographical--species definition would place all hominins in a single, phenotypically diverse species. Since divergence from the chimpanzee, "species" distinctness in hominins may have been maintained by temporary allopatry and centripetal niche separation. The hominin lineage may have evolved as a single, phenotypically diverse, reticulately evolving species. PMID:14655873

  16. From the bush to the bench: the annual Nothobranchius fishes as a new model system in biology.

    Science.gov (United States)

    Cellerino, Alessandro; Valenzano, Dario R; Reichard, Martin

    2016-05-01

    African annual fishes from the genus Nothobranchius are small teleosts that inhabit temporary water bodies subject to annual desiccation due to the alternation of the monsoon seasons. Given their unique biology, these fish have emerged as a model taxon in several biological disciplines. Their increasing popularity stems from the extremely short lifespan that is the result of their specific life-history adaptations and is retained under laboratory conditions. Nothobranchius furzeri, the most popular laboratory species, is the vertebrate species with the shortest lifespan recorded in captivity. In the laboratory, adults of different Nothobranchius species and populations live between 3 and 18 months and, notably, there is a negative correlation between the captive lifespan of a species and the aridity of their habitat. Their short lifespan is coupled to rapid age-dependent functional decline and expression of cellular and molecular changes comparable to those observed in other vertebrates, including humans. The recent development of transgenesis in this species makes it possible to insert specific constructs into their genome, and the establishment of transgenic lines is facilitated by their very rapid generation time, which can be as short as 1 month. This makes Nothobranchius species particularly suited for investigating biological and molecular aspects of ageing and ageing-associated dysfunctions. At the same time, they also represent a unique model taxon to investigate the evolution of life-history adaptations and their genetic architecture. We review their natural history, including phylogenetic relationships, distribution in relation to habitat conditions and natural selection for differential longevity, population structure and demography, and life cycle with emphasis on diapause that may occur at three stages during embryonic development. We further critically evaluate their use as a laboratory model for understanding the evolution of a rapid ageing rate and its consequences for other life-history traits, for cellular, molecular and integrative traits associated with the ageing process, high incidence of neoplasias, their utility for genome-wide gene-expression studies, and as a model for quantitative genetics. We summarize recent achievements in fostering Nothobranchius species as a widely applicable model system, including an annotated transcriptome, successful transgenesis, and existence of viable inbred lines. We compare the conditions they experience in the wild and in captivity and suggest that they are an ideal taxon to investigate natural genetic variation in a laboratory setting. We conclude that Nothobranchius species - and N. furzeri in particular - could become a unique model taxon that bridges interests in ecological and biomedical research. We hope that a conceptual and methodological integration of these two branches of biology will provide important new insights. PMID:25923786

    2016-05-03

    The present invention relates to novel diacylglycerol acyltransferase genes and proteins, and methods of their use. In particular, the invention describes genes encoding proteins having diacylglycerol acetyltransferase activity, specifically for transferring an acetyl group to a diacylglycerol substrate to form acetyl-Triacylglycerols (ac-TAGS), for example, a 3-acetyl-1,2-diacyl-sn-glycerol. The present invention encompasses both native and recombinant wild-type forms of the transferase, as well as mutants and variant forms. The present invention also relates to methods of using novel diacylglycerol acyltransferase genes and proteins, including their expression in transgenic organisms at commercially viable levels, for increasing production of 3-acetyl-1,2-diacyl-sn-glycerols in plant oils and altering the composition of oils produced by microorganisms, such as yeast, by increasing ac-TAG production. Additionally, oils produced by methods of the present inventions comprising genes and proteins are contemplated for use as biodiesel fuel, in polymer production and as naturally produced food oils with reduced calories.

    Full Text Available Metastatic lesions of renal cell carcinoma (RCC occasionally regress spontaneously after surgical removal of the primary tumor. Although this is an exceptionally rare occurrence, RCC has thus been postulated to be immunogenic. Immunotherapies, including cytokine therapy, peptide-based vaccines, and immune checkpoint inhibitors have therefore been used to treat patients with advanced, metastatic RCC. We review the history, trends, and recent progress in immunotherapy for advanced RCC and discuss future perspectives, with consideration of our experimental work on galectin 9 and PINCH as promising specific immunotherapy targets.

    Essential oils were extracted by hydrodistillation from the traditional Australian medicinal plant Eremophila bignoniiflora, characterized chemically and then screened for bioactivity. Characterization and quantification were completed using gas chromatography-mass spectrometry (GC-MS) and GC-flame ionization detection, respectively. Antimicrobial capacity was assessed using disc diffusion and micro-titre plate broth dilution and further characterized using thin layer chromatography followed by bioautography to assign activity to separated individual active components. Antifungal capacity was investigated using micro-titre plate broth dilution against pathogenic Trichophyton species. Free radical scavenging ability was assessed using the diphenylpicrylhydradyl reaction in methanol. The predominant components of the essential oil were fenchyl-acetate and bornyl-acetate. However, bioautography indicated antimicrobial ability to be largely linked to the less abundant, more polar constituents. Oils displayed only modest antifungal ability against pathogenic Trichophyton species associated with dermatophytosis, but moderate to high antimicrobial activity, particularly against the yeast Candida albicans and the bacteria Staphylococcus epidermidis. Essential oils exhibited relatively low free radical scavenging ability. Speculation over the role of essential oils in the traditional medicinal applications of E. bignoniiflora follows, exploring correlations between traditional use and investigated bioactivities.

    Full Text Available The studies refer to the phenomenon of hyperparasitism in the municipal environment. The paper presents the occurrence of fungi of the genus Ampelomyces on Erysiphales – important group of phytopathogenic fungi. For the first time in Poland analyzed degree of infestation of Erysiphales mycelium by Ampelomyces and effect of the hyperparsites on the degree of infestation plants by Erysiphales. The high participation of the Ampelomyces was noted in each year of the study. Substantial differences were noted in the occurrence of Ampelomyces depending on the developmental stage of the host fungi and considerable differences in the prevalence of the hyperparasites on particular Erysiphales species. In all cases examined, the mean index of infestation of host plants by Erysiphales was higher than the mean degree of infestation of powdery mildew mycelium by Ampelomyces. The results indicate that under natural conditions they do not play any significant role in the reduction of the degree of infestation of host plants by Erysiphales and do not disturb drastically their life cycle.

  9. Bearing structures

    International Nuclear Information System (INIS)

    A hydrostatic bearing for the lower end of the vertical shaft of a sodium pump comprises a support shell encircling the shaft and a bush located between the shell and shaft. Liquid sodium is fed from the pump outlet to the bush/shaft and bush/shell interfaces to provide hydrostatic support. The bush outer surface and the shell inner surface are of complementary part-spherical shape and the bush floats relative to the shaft so that the bush can align itself with the shaft axis. Monitoring of the relative rotational speed of the bush with respect to the shaft (such rotation being induced by the viscous drag forces present) is also performed for the purposes of detecting abnormal operation of the bearing or partial seizure, at least one magnet is rotatable with the bush, and a magnetic sensor provides an output having a frequency related to the speed of the bush.

    In this paper, the polyploidy-induction effects of colchicine on pepper Capsicum annuum L. With different concentration (0. 01%, 0. 03%, 0. 05%) and treated time (2 d, 4 d, 6 d) were studied. The results showed that the chromosome number of variant plants varied with cells which had 4 n = 48 chromosomes and some was 2 n = 24 chromosomes. Contrasted to normal diploid plants (ck), the induced plants exhibited the morphologic characteristics with thicker and larger leaves, larger stomata and stronger stems with longer length per stem stalk. Relevant indexes all showed significant or extreme significant differences, and the difference increased with intensity of treatment. Induced plants showed chimera through ploidy determinion (2 n to plant chimeras 2 n = 24 or 48). With the same treating time, the polyploidy-induction effects of colchicine on pepper Capsicum annuuml was different in different concentration, but in the same concentration, the number of leaves and stomata of induced plant had no obvious difference with different treating time(p >0.05), but others had extreme difference(p < 0.01). There had some interaction between colchicine concertration and treating time. In all treatments, only stomato area had no obvious difference, the others indexes were different significantly or extreme significantly each other. Based on the integrative analysis, it was concluded that the best combination of colchicine solution concentration and processing time was the best combination of 0.05% induced 6d, and the induction rate could reach 26.1 %.%以秋水仙素为诱变剂,比较了不同浓度和不同处理时长组合下辣椒(Capsicum annuum L.)的生长差异和多倍体诱导效应.结果表明:和对照植株相比,所有处理变异植株在形态上表现为叶片宽大,叶色较深,茎变粗且节间距长,气孔增大;相关指标都表现出显著或极显著的差异,而且随着处理强度的增加差异更为明显.秋水仙素诱导产生的变异植株经染色体倍性鉴定植株表征为嵌合体(2 n=24或2 n=48).相同处理时长下,不同浓度秋水仙素溶液对辣椒多倍体诱导效应差异显著,而对相同浓度下不同处理时长对植株叶片数和气孔面积影响差异不显著(P>0.05),其它指标差异极显著(P<0.01).秋水仙素浓度与处理时长之间存在交互作用,不同处理之间除气孔面积差异不显著之外,其它指标间差异显著或极显著.结合加倍率和植株死亡率综合分析后认为,用0.05%的秋水仙素溶液处理6天诱导效果最佳,诱导诱导加倍率可达26.1%.

Love making under sacrificial tree gave birth to large number of emperors and sages in ancient times . It is a portrayal of the primitive marriage customs , and a reflection of the traditional Chinese cultural conception of the unity of heaven and man .“The desire for food and sex is part of human nature .” This saying depicts the plain life style of ancient people , and has been the life ideals advocated by confucianists . A review of the history in this period helps us to understand our ancestors'aw areness of heaven and earth , and therefore no longer view the recurring descriptions of “Wushan's clouds and rain” , and“date in mulberry bushes”as odd tales . It also enables us to have a more profound understanding of the origin of the traditional culture . There will be no more wonder in knowing that Book of Songs once was considered as pornographic poetry .%古代的社祭隆重而不乏温情,在祭拜土神的同时,社祭典礼还为青年男女提供了相会和交流的最好机遇,因为土地神不仅主宰大地的生养,还是人们婚姻的媒神。社祭树下的媾合孕育了一大批古代的帝王与圣贤,这是人类原始婚姻状态的写照,更是中国传统文化天人合一理念的反映。“食色性也”,描摹了古人朴素的生活方式,一直是儒家倡导的人生理想。

The second experiment was conducted in the presence of light at a temperature of 30ºC and consisted of a 4 x 3 factorial design, with 4 storage times (0, 6, 12 and 18 months and the 3 three harvest physiologic stages used in the previous experiment. Both of the experiments were conducted in randomized blocks, with 4 replications of 100 seeds. Light did not affect germination. By contrast, a temperature of 20ºC retarded the germination process, although the percentage of germinating seeds was not affected. Seed storage and the different harvest physiologic stages affected the Speed of germination index (SGI and the germination percentage. Seeds that were harvested at the more mature stage (dark brown color could be stored for up to 18 months.O presente trabalho teve como objetivos avaliar a influência da luz, da temperatura, do estádio fisiológico na colheita e do armazenamento na germinação das sementes de Hyptis marrubioides. Foram realizados dois experimentos, sendo o primeiro implantado logo após a colheita das sementes, constituído por um fatorial 2 x 3 x 3, com 2 ambientes (luz e escuro x 3 temperaturas (20, 30 e 20/30ºC x 3 épocas de colheita das sementes (sementes com coloração verde, coloração marrom claro e coloração marrom escuro. O segundo experimento, em presença de luz e à temperatura de 30ºC, foi constituído por um esquema fatorial 4 x 3, sendo 4 tempos de armazenamento (0, 6, 12 e 18 meses e 3 três estádios fisiológicos de coleta mencionados no experimento anterior. Ambos os experimentos foram implantados no delineamento em blocos ao acaso, com quatro repetições de 100 sementes. Foi verificado que o fator luz não influenciou a germinação. Por outro lado, a temperatura de 20ºC retardou a germinação, apesar de não influenciar a sua porcentagem. O armazenamento e os diferentes estádios fisiológicos de colheita das sementes influenciaram o IVG e a porcentagem de germinação. Sementes coletadas no estádio mais maduro (coloração marron escuro demonstraram ser apropriadas para o armazenamento por até 18 meses.

    Full Text Available We focused our study on the effects of Larrea cuneifolia phenolic resin on leaf-cutting ants from two populations (Sierra de las Quijadas National Park and San Roque of Acromyrmex lobicornis in San Luis, Argentina. We conducted two bioassays of food choice (field and laboratory to compare the effects of phenolic resin on ant workers from these two populations. Results of the field experiment indicated that there were no differences in preference for either leaves treated with resin or untreated leaves among colonies from both localities. However, results of the laboratory experiments with individual ants indicated a significant effect of population and treatment on the time spent in different treatments. While leaf-cutting individual workers from Quijadas preferred the phenolic resin, workers from San Roque avoided it. These results evidence that ants respond according to time of exposure to chemicals from plants (presence or absence and that the effects of resin among a population can be observed and measured on individual ant workers, even in the absence of fungus garden influences in the nest.Este estudio se ha centrado en los efectos que produce la resina fenólica de Larrea cuneifolia sobre dos poblaciones distintas (Parque Nacional de Sierra de las Quijadas y la localidad de San Roque de Acromyrmex lobicornis en San Luis, Argentina. Se disenaron dos tipos de bioensayos (a campo y en laboratorio para comparar los efectos de la resina fenólica sobre las hormigas obreras de estas dos poblaciones. Los resultados de los experimentos de elección de la oferta alimentaria en el campo, indicaron que no hubo ninguna diferencia de preferencia entre las colonias, ni por las hojas tratadas con resina ni por las hojas sin tratar para ambas localidades. Sin embargo, los resultados de los experimentos de laboratorio con las hormigas obreras individualmente indicaron efectos significativos entre las poblaciones y entre los tratamientos. Mientras que las hormigas obreras de Quijadas prefirieron la resina fenólica, las obreras de San Roque la rechazaron. Estos resultados evidencian que las hormigas responden de acuerdo al tiempo de exposición a los productos naturales de las plantas (presencia y ausencia y que los efectos de la resina entre poblaciones, puede ser observada y medida en las hormigas obreras aun en ausencia de la influencia del jardín de hongos de la colonia.

    @@ A year of anti-terrorist war has passed since President Bush declared war on Afganistan on October 7,2001. In the course of the war, Bush's anti-terrorist strategic thinking has been enriched and perfected gradually as the war develops in greater depth and was finally formed as so-called "Bushism" ,which has become the guideline not only for the American war on anti-terrorism, but also for the Bush administration's external strategy. It is exerting profound impact on international politics and international relations.

    Direct contract between the sealed liquid and the magnetic fluid in a dynamic system under magnetic field may lead to an unstable interface, consequently, break down the seal. Aiming at this problem, a new magnetic fluid seal (MFS) was developed. In this new MFS, a soft iron bushing with high permeability was introduced on the shaft and nonferrous shields were installed beside the bushing and the pole pieces. The parameters of the bushing and the shields were optimized in a seal simulation facility. The results show that the bushing with a thickness of 7 mm and shields with a width of 8 mm are best for sealing a shaft 20 mm in diameter. The MFS designed based on the optimum parameters shows good performance and long life span for sealing lubricating oil.

    This article examines the effect of Bush administration's human rights preferences during the war on terror with respect to torture by analysing a large-n sample of public legitimation strategies of both the United States and other members of international society. The article asks two questions......: first, has the defection of the United States from these human rights norms led to a ‘norm cascade’ that delegitimized the norms? Second, did the material preponderance of the United States help it to legitimate its preferences in international society? The article argues that despite initial ambiguity...... in the response to the Bush administration's preferences from key liberal states, there is little evidence by the end of the Bush administration's term that a core group of states supported their preferences, nor did its material preponderance help the Bush administration to legitimate its position....

    Overabundance of deer can assist the intrusion of invasive plants through browse, leading to homogenization of plant communities. Public attitudes towards native and invasive plant species and white-tailed deer browse related to personal experiences, can be changed through education focusing public awareness of ramifications of deer browse on native and invasive plants. I developed an interactive, interpretive Self-Guided Walking Tour brochure of the "You Can Trail" to provide an educational outreach program for visitors of Crooked Creek Environmental Learning Center that includes ecologically important native and invasive plants species from my investigation. This research study focuses on the overall abundance of native and invasive plant species once Odocoileus virginianus have been removed from the landscape during collection periods in June and September 2013 from exclosure and access plots that were maintained for seven years. Similarity of abundance were found in native and invasive abundance of forbs, bushes and percentage of ground cover. Differences included native bush volume being greater than invasive bush volume in the access plot in June with opposing results in the exclosure plot, being greater in invasive bush volume. However, in September, native and invasive bush volume was similar within the exclosure plot, while invasive bush volume decreased in the access plot. Invasive vines recorded in the June access plot were absent in the September collection period.

    Full Text Available Creating genotypes that will be characterized by high yields, good quality and other favorable agronomic characters is a major objective of most currant breeding programs worldwide. For easier and faster achievement of these goals and identification of superior genotypes suitable for use as parents in future hybridization programs, study of genetic parameters seems to be obligatory. In this regard, the aims of our study were to estimate components of variability and heritability, and do correlation analysis for yield components in order to determine efficient strategies for improving yield in black currant breeding programs. Significant differences between cultivars were established for all studied traits. A high proportion of genotypic variance was found with bush width, no. of shoots per bush, bunch weight and berry weight indicating that genetic improvement for these traits through breeding was achievable. Opposite, seasonal variance was high for bush height, no. of bunch per bush and yield. The high heritability coefficients (0.80-0.94 detected for all traits studied reflect the close agreement between their phenotypic and genotypic values. Also, most pairs of traits were similarly correlated at both phenotypic and genotypic levels. So, yield was significantly and positively correlated with bush height, no of bunch per bush and bunch weight. These results imply a rapid response of black currants to selection.

  12. Removal and replacement of fuel rods in nuclear fuel assembly

    International Nuclear Information System (INIS)

    To remove the bottom nozzle of a nuclear fuel assembly, the nozzle plate must be disconnected from the control-rod thimbles. For nozzles whose control-rod thimbles are connected to the nozzle plate by screw fasteners having lock pins welded to the nozzle plate, a cutter for severing the welds is provided. The cutter is rotated by a motor at the work position through a long floating shaft. A long feed shaft operated by a thumb nut at the work position feeds the floating shaft and cutter downwardly through the weld. The bushings extend from a bushing plate, each encircling a screw fastener. Each bushing has a yieldable sleeve for sealing the region around a screw fastener to trap the chips from the severed weld. The cutter is indexed from weld to weld by indexing plates. To remove chips adhering to the cutter, the suction tube of a suction-pump-operated eductor is inserted in the auxiliary hole and the cutter is inserted in the bushing and chips are removed by suction. By inserting the suction tube into the bushings which seal the regions around the screw fasteners and enabling the eductor, the captured chips may be removed. Once the welds are severed the screw-fasteners may be unscrewed and removed by the eductor. The bottom nozzle may then be removed

  13. Void-free epoxy castings for cryogenic insulators and seals

    International Nuclear Information System (INIS)

    The design of the Westinghouse Magnet for the Oak Ridge National Laboratory's Large Coil Program (LCP) incorporates a main lead bushing which transmits heat-leak loads by conduction to the supercritical helium stream. The bushing, which consists of epoxy resin cast about a copper conductor, must be electrically insulated, vacuum tight and be capable of withstanding the stresses encountered in cryognic service. The seal design of the bushing is especially important; leakage from either the helium system or the external environment into the vacuum will cause the magnet to quench. Additionally, the epoxy-resin casting must resist mechanical loads caused by the weight of leads attached to the bushing and thermal stresses transmitted to the epoxy via the conductor. The epoxy resin is cast about the conductor in such a way as to provide the required vacuum tight seal. The technique by which this is accomplished is reviewed. Equally important is the elimination of voids in the epoxy which will act as stress-concentrating discontinuities during cooling to or warming from 4K. The types of voids that could be expected and their causes are described. The paper reviews techniques employed to eliminate voids within the cast-resin portion of the bushing

    2007-01-01

    The high-speed multi-cycle impact and speed, load fluctuant characteristics of a kind of narrow-width automotive engine oil-pump chain 06BN-1 are studied through engine assembly and road-drive tests to satisfy the light-weight demand of engine. The worn surface morphologies of rubbing area between pin, bush and roller are also analyzed based on scanning electron microscope. The results show that the main wear mechanism of automotive engine oil-pump chain is fatigue wear, and it's failure mechanism is the forming, extending and flaking of cracks on top layer of pin and bush. Pin and bush both occurred cycle-soften phenomenon, and roller occurred cycle-harden. Fretting wear is one of the most important "fall to pieces" failure causes of automotive chain. Ensuring sufficient strength and plasticity of roller, as well as adopting suitable shaping technology are the effective methods to increase its resistance to multi-cycle impact.

    International Nuclear Information System (INIS)

    A conduit coupling assembly for coupling pipes with an interposed seal has a first part for receiving a pipe and is in splined engagement with a bush fixed to a pipe. A second part having radial fingers so that it can be turned by a manipulator, has a threaded engagement with the first part which is the same hand but different pitch to a threaded engagement between the second part and the bush. Pitches of 8:7 for couplings will give a mechanical advantage of 56:1 thus reducing the force needed to obtain a given axial movement of the bush and thus of the pipe and compression of the seal.

  1. Some aspects of stray losses in large power transformers

    International Nuclear Information System (INIS)

    The paper presents some results of the investigation of stray losses in power transformers that are caused by high-current loops. The investigation was focused on: a) additional losses in tank cover around high-current bushings and the way of their reduction, b) extra leakage flux and additional losses due to high current delta-connections. The insertion of nonmagnetic gaps between the phase bushings reduces the extra cover losses more than three times. A nonmagnetic plate around the high-current bushings reduces these extra losses practically to zero. The extra losses due to the high-current delta-connections could be significant for the transformer loss level. These extra losses could be controlled (reduced) by the design layout of the delta-connections. (Author)

  3. Design and installation of extra high voltage cryogenic dielectric test facilities for the superconducting electric equipment

    International Nuclear Information System (INIS)

    We installed high voltage cryogenic dielectric test facilities including big FRP cryostat. We designed 3 m long and 2 m wide cryostat system with busing. Low temperature and high voltage bushing were fabricated and tested. CF4 gas shows excellent characteristics in low temperature insulation. High voltage bushing could be modified for low temperature environment. Superconducting electric equipments have a lot of advantages over the conventional devices such as improvements in overall efficiency, size reduction, high current carrying capability, and also environment-friendly products. Owing to these advantages, many research institutes have been tried to develop commercial superconducting devices, which could be applicable to the high voltage and high current electric networks. But up to now, most of the research works to develop commercial products were delayed because it was not easy to acquire reliable high voltage insulation properties and optimum insulation design skills considering extremely low temperature environments. Furthermore, it was difficult to determine optimum high voltage insulation level due to the lack of high voltage cryogenic dielectric test facilities. Thus, in order to establish the cryogenic dielectric technology regarding insulating design, cryogenic dielectric test skills, and to implement more reliable high voltage superconducting devices, high voltage cryogenic dielectric test facilities should be prepared for extra high voltage superconducting electric equipments. Recently, cryogenic dielectric test facilities were installed including 3 m long 2 m wide cryostat system with bushing, and 1.6 MVA lightening impulse generators, 400 kVA AC overvoltage test system in Korea. In this paper, design and installation of high voltage cryogenic dielectric test system including very big size FRP cryostat and high voltage bushing were minutely introduced. And some test results to develop high voltage bushings for liquid nitrogen cryostat in order to

    2004-12-01

    Full Text Available This paper is one of a series produced as part of an evaluation of a number of digital interactive television (DiTV health pilots funded by the Department of Health during 2001/2002. This paper is concerned with two pregnancy health services produced by Channel Health and hosted on Sky television. The study aimed to discover the success or otherwise of health information on pregnancy in this form and on this medium or ‘platform’. In particular we were interested in what kinds of people on the broader national stage viewed the Bush Babies programme. Data were obtained through a telephone questionnaire of Channel Health users. More than 250 people took part. More than 175 000 households watched the programmes, a large audience for this type of programme. Bush Babies attracted a sizeable audience with over a quarter of Channel Health viewers in this study having seen it. There proved to be marked differences between the types of people using the service and in the patterns of their use – and not always in the ways one might have expected. As expected, people who were single, older or male were less likely to view Bush Babies, while younger, married or cohabitants and females were more likely to watch the programme. More unexpectedly, perhaps, the fact that the person was pregnant was not a predictor of whether they saw a Bush Babies programme or the number of the programmes watched.

    This study was carried out to examine the effect of low doses of radiation on germination of plant seeds. The seeds were irradiated by γ rays ranging from 0 to 30 Gy. After irradiation, the seeds were sown in petri dishes and held in incubators regulated at 20degC for spinach and pea, and at 25degC for bush bean. The results were as follows: 1. When germination bed was very moist, germination rates and germination percent-ages of irradiated spinach and bush bean seeds were higher than those of non-irradiated seeds. 2. When spinach seeds were storaged for one year at 20∼25degC, germination rate and germination percentage of irradiated seeds were higher than those of non-irradiated seeds. 3. When moisture contents of pea and bush bean seeds before irradiation were about 11 % in dry seeds and about 45 % in moist seeds, germination rate of dry irradiated pea seeds, and germination rate and germination percentage of irradiated moist bush bean seeds were higher than those of non-irradiated seeds.

  11. Curse Of The Desert? Magic Realism And The Pitfalls Of Setting In Bessie Head’s Maru And Ben Okri’s Starbook

    Directory of Open Access Journals (Sweden)

    Wazha Lopang

    2014-07-01

    Full Text Available This paper argues that magic realism cannot evolve in a setting where there is no bush environment because this is where oral literature flourishes. The oral literature provides the conditions necessary for magic realism to explore the relationship between the surreal and the mundane. If the magic realism is set outside this bush environment then the experience becomes muted. Texts that have a clear dichotomy between the world of human habitation (such as villages, towns and that of the spirits (such as the bush or forest enable magic realism to evolve into a more profound experience, that of the dream setting. My argument is that the dream setting needs this dichotomy for it to exist. In essence, texts that do not use the bush environment as part of their setting fall short in their creative aspect because the space and time within which characters function are constrained. The use of the oral tradition with its interplay of the human, animal and spirit worlds creates a platform for the dream setting, something which cannot happen where the setting limits itself to the world of human habitation. I will compare Bessie Head’s Maru with Ben Okri’s Starbook to show how the oral tradition in the latter text makes it achieve a level of magic realism that cannot be possible in Head’s Maru.
