    A ""bush telegraph"" is an antipodean slang noun phrase for a ""grapevine"" or an informal network of communication. The title of this book on English language use comes from the fact that the book is written from the southern hemisphere (where the idea of a ""bush telegraph"" is more widely-known) and because the concept of a ""bush telegraph"" describes what the book provides - a discussion of salient points in English language use and tertiary teaching across branches of interrelated interests. Each chapter of Bush Telegraph describes aspects of English writing culture. Separately and toget

    The manufacture of electrode insulators that are mechanically strong, shock-proof, vacuum tight, and are capable of withstanding gas pressures of many atmospheres under intense neutron bombardment, such as may be needed in an ionization chamber, is described. The ansulator comprises a bolt within a quartz tube, surrounded by a bushing held in place by two quartz rings, and tightened to a pressure of 1,000 pounds per square inch by a nut and washer. Quartz is the superior material to meet these conditions, however, to withstand this pressure the quartz must be fire polished, lapped to form smooth and parallel surfaces, and again fire polished to form an extremely smooth and fracture resistant mating surface.

    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 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.

    Research into a novel type of compact bushing is being conducted through the HVIV (High Voltage holding In Vacuum) partnership between CEA-Cadarache1, GeePs-Centralesupélec4, LPGP3 and LCAR2. The bushing aims to concentrate the high electric field inside its interior, rather than in the vacuum tank. Hence the field emission current is also concentrated inside the bushing and it can be attempted to suppress this so-called dark current by conditioning the internal surfaces and by adding gas. LCAR have performed theoretical quantum mechanical studies of electron field emission and the role of adsorbates in changing the work function. LPGP studied the ionization of gas due to field emission current and the behavior of micro particles exposed to emissive electron current in the vacuum gap under high electric fields. Experiments at Geeps have clarified the role of surface conditioning in reducing the dark current. Geeps also found that adding low pressure nitrogen gas to the vacuum is much more effective than helium in reducing the field emission. An interesting observation is the growth of carbon structures after exposure of an electrode to the electric field. Finally, IRFM have performed experiments on a single stage test bushing that features a 36 cm high porcelain insulator and two cylindrical electrode surfaces in vacuum or low-pressure gas. Using 0.1 Pa N2 gas, the voltage holding exceeded 185 kV over a 40 mm "vacuum" gap without dark current. Above this voltage, exterior breakdowns occurred over the insulator, which was in air. The project will finish with the fabrication of a 2-stage compact bushing, capable to withstand 400 kV.

    Full Text Available In November 2004, presidential elections took place in the United States. President George W. Bush, a Republican, confronted Democratic candidate John F. Kerry. A very close race was expected, focusing on the economic situation of the country and national security, but it was the latter the one which prevailed during the campaign, even as significant participation was motivated by the issue of “moral values”. It was thought that due to the closeness of the contest, any of the sides could appeal to judicial tribunals, just like four years before. At the end, President Bush achieved a clear victory; both in the popular vote and the electoral college, and his party increased its majorities in both chambers of Congress.

  11. Injection molding of bushes made of tribological PEEK composites

    Directory of Open Access Journals (Sweden)

    2007-12-01

    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.

    President Bush complained yesterday about the "filth and indecent material" that Americans are exposed to through televised trials. Mr. Bush also criticized programs to combat AIDS that give condoms to teenagers and clean needles to drug addicts. He said such efforts undermine traditional values. He expressed hope that Earvin "Magic" Johnson's revelation that he is HIV positive "will teach people that wayward lifestyles or just kind of unsafe sex at random is not the way it ought to work." Mr. Bush made the comments in a series of satellite television interviews with ABC affiliates in major cities. In an apparent reaction to graphic testimony at the recent Palm Beach rape trial of William Kennedy Smith, Mr. Bush said, "I think the American people have a right to be protected against some of these excesses." Mr. Smith, a nephew of Sen. Edward M. Kennedy, D-Mass., was acquitted last week. The Cable News Network and Court TV provided virtually gavel-to-gavel coverage. Mr. Bush took a dim view of a plan to distribute condoms to juniors and seniors in Philadelphia city high schools as part of a program to combat acquired immune deficiency syndrome. "This is a disease that can be controlled for the most part by individual behavior," Mr. Bush said. "Indeed, I must tell you I'm worried about it. I'm worried about so much filth and indecent material coming in through the airwaves and through these trials into people's homes," he said. full text

    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

  1. Sacrifice, the Bush Way: From Self to Others.

    2016-01-01

    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.

    The deterioration of electrical bushings can compromise the safety of power system equipment. This paper discussed an online monitoring method for the condition-based maintenance (CBM) of power system bushings. Temperature fields were modelled using the finite element method. The bushing model considered extreme thermal stresses and focused on the first cooling wing section of the ceramic insulator. The system was designed to monitor the time variation of dielectric losses and bushing capacity levels. Heat produced by Joule losses from the central conductor of the bushing were also considered. Results of the study showed that the method accurately monitored the evolution of the dielectric loss factor at the terminals of bushings and identified bushings with high dielectric losses. A numerical recursive filter was used to reject disturbances generated by atmospheric events. The program also calculated coefficients for reference voltage and bushing test taps. Results of a case study conducted in Craiovia demonstrated that the method accurately and continuously monitored the bushing while filtering out dielectric losses caused by environmental factors. 12 refs., 12 figs.

    High Voltage Bushing (HVB) is the key component of Diagnostic Neutral Beam (DNB) system of ITER as it provides access to high voltage electrical, hydraulic, gas and diagnostic feedlines to the beam source with isolation from grounded vessel. HVB also provides primary vacuum confinement for the DNB system. Being Safety Important Class (SIC) component of ITER, it involves several configurational, technological and operational challenges. To ensure its operational performance & reliability, particularly electrostatic behavior, half scale down Prototype High Voltage Bushing (PHVB) is designed considering same design criteria of DNB HVB. Design optimization has been carried out followed by finite element (FE) analysis to obtain DNB HVB equivalent electric stress on different parts of PHVB, taking into account all design, manufacturing & space constraints. PHVB was tested up to 60 kV without breakdown, which validates its design for the envisaged operation of 50 kV DC. This paper presents the design of PHVB, FEA validation, manufacturing constraints, experimental layout with interfacing auxiliary systems and operational results related to functional performance.

    1995-11-01

    Geophysical studies in shallow waters adjacent to the Bush River Peninsula, Edgewood Area of Aberdeen Proving Ground, Maryland, have delineated the extent of waste disposal sites and established a hydrogeologic framework, which may control contaminant transport offshore. These studies indicate that during the Pleistocene Epoch, alternating stands of high and low sea levels resulted in a complex pattern of shallow channel-fill deposits around the Bush River Peninsula. Ground-penetrating radar studies reveal paleochannels greater than 50 ft deep. Some of the paleochannels are also imaged with marine seismic reflection. Conductivity highs measured with the EM-31 are also indicative of paleochannels. This paleochannel depositional system is environmentally significant because it may control the shallow groundwater flow regime beneath the peninsula. Magnetic, conductivity, and side-scan sonar anomalies outline anthropogenic anomalies in the study area. On the basis of geophysical data, underwater anthropogenic materials do exist in some isolated areas, but large-scale offshore dumping has not occurred in the area studied.

  5. Bush Encroachment Mapping for Africa - Multi-Scale Analysis with Remote Sensing and GIS

    Science.gov (United States)

    Graw, V. A. M.; Oldenburg, C.; Dubovyk, O.

    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.

  6. Mapping Bush Encroaching Species by Seasonal Differences in Hyperspectral Imagery

    Jens Oldeland

    2010-05-01

    Full Text Available Bush encroachment is a form of land degradation prominent worldwide, but particularly present in semi-arid areas. In this study, we mapped the spatial distribution of the two encroacher species, Acacia mellifera and Acacia reficiens,in Central Namibia, based on their different phenological behavior. We used constrained principal curves to extract a one dimensional gradient of phenological change from two hyperspectral images taken in different seasons. Field measurements of species composition and cover values were statistically related to bi-temporal differences in hyperspectral vegetation indices in a direct gradient analysis. The extracted gradient reflected the relationship between species composition and cover values, and the phenological pattern as captured by the image data. Cover values of four dominant plant species were mapped and species responses along the phenological gradient were interpreted.

    1996-12-31

    The Savannah River Site (SRS) and the Savannah River Technology Center (SRTC) are combining their existing experience in handling highly radioactive, special nuclear materials with commercial glass fiberization technology in order to assemble a small vitrification system for radioactive actinide solutions. The vitrification system or {open_quotes}brushing{close_quotes}, is fabricated from platinum-rhodium alloy and is based on early marble remelt fiberization technology. Advantages of this unique system include its relatively small size, reliable operation, geometrical safety (nuclear criticality), and high temperature capability. The bushing design should be capable of vitrifying a number of the actinide nuclear materials, including solutions of americium/curium, neptunium, and possibly plutonium. State of the art, mathematical and oil model studies are being combined with basic engineering evaluations to verify and improve the thermal and mechanical design concepts.

  8. High Throughput Phenotyping of Blueberry Bush Morphological Traits Using Unmanned Aerial Systems

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Phenotyping morphological traits of blueberry bushes in the field is important for selecting genotypes that are easily harvested by mechanical harvesters. Morphological data can also be used to assess the effects of crop treatments such as plant growth regulators, fertilizers, and environmental conditions. This paper investigates the feasibility and accuracy of an inexpensive unmanned aerial system in determining the morphological characteristics of blueberry bushes. Color images collected by a quadcopter are processed into three-dimensional point clouds via structure from motion algorithms. Bush height, extents, canopy area, and volume, in addition to crown diameter and width, are derived and referenced to ground truth. In an experimental farm, twenty-five bushes were imaged by a quadcopter. Height and width dimensions achieved a mean absolute error of 9.85 cm before and 5.82 cm after systematic under-estimation correction. Strong correlation was found between manual and image derived bush volumes and their traditional growth indices. Hedgerows of three Southern Highbush varieties were imaged at a commercial farm to extract five morphological features (base angle, blockiness, crown percent height, crown ratio, and vegetation ratio associated with cultivation and machine harvestability. The bushes were found to be partially separable by multivariate analysis. The methodology developed from this study is not only valuable for plant breeders to screen genotypes with bush morphological traits that are suitable for machine harvest, but can also aid producers in crop management such as pruning and plot layout organization.

    This paper presents a calculator to facilitate assessments of ingestion doses from Aboriginal bush foods. The calculator combines information on traditional diet and land use with radionuclide concentration ratios and ingestion dose coefficients to estimate doses. The calculator was applied to the planned remediation of Ranger uranium mine to derive a set of scaling factors between radionuclide activity concentrations in environmental media and ingestion dose from bush foods. The scaling factors can be used to estimate doses from bush foods once the post-remediation radiological conditions of the mine and surrounding environment are known. Crown Copyright © 2017.

  14. Nonlinear Transient Modeling and Design of Turbocharger Rotor/Semi-Floating Bush Bearing System

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available This work presents the bearing design and analysis of radial semi-floating bush oil lubricated bearings for a typical industrial turbocharger configuration. Initially, the stability analysis for a linear rotor/bearing system is evaluated through eigenvalues and eigenvectors. The stiffness and damping coefficients of the inner oil film are obtained for the linear modeling process. The operating speed range of the turbocharger is high enough, at 21,000 to 24,000 rpm, to be unstable, indicating that the analysis should be and is carried out with nonlinear transient modeling. The nonlinear transient analysis evaluates the rotor and bush limit cycle orbits, rotor dynamics, the forces acting on the rotor and semi-floating bush surfaces, the oil flow through the bearing, the oil temperatures, and the power loss of the two oil films. The optimum design of a set of semi-floating bush bearings for this application depends strongly upon the clearances of the bush and squeeze film damper, usually expressed as the non-dimensional clearance to radius ratio. A typical clearance is evaluated to determine the bearing performance in terms of orbit size, forces acting on the bush and squeeze damper surfaces, oil flow through the bearing, power loss, and thermal heating. The nonlinear transient orbit values are evaluated for frequency content using the FFT to determine which orbits show both the synchronous and sub-synchronous vibration components and the associated rotor modes excited. These results are compared to the linear analysis over the operating speed range. The oil flow through the bearing component is much larger than the squeeze film damper. The forces acting on the bush and squeeze damper surfaces are related to the fatigue life of the bearing.

    Tanaka, Shinji; Zuo, Siyang; Hikam, Achmad; Toyama, Toshiyuki

    A swing type refrigerant compressor was developed in order to overcome problems related to lubrication of a rotary compressor. However, the lubrication condition of the swing compressor has not been measured quantitatively yet. This paper describes an application of an eddy current displacement sensor to measure oil film thickness of a sliding part between a suction side bush and a blade in the swing compressor, and examined lubrication condition of the sliding part and a motion of the bush against the blade under some operating conditions. The results indicate that the sliding part between the suction side bush and the blade forms a wedge shape in shaft angle from 0° to 180° and forms a negative wedge shape in shaft angle from 180° to 360°. In addition, the results show that the oil film thickness on an upper edge side of the bush and a slope angle of the bush against the blade decrease with an increase of discharge pressure and increase with an increase of operating frequency of the compressor.

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

    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.

    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.

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. L’administration Bush est accusée d’avoir utilisé les FBI et l’argent public pour obtenir des gains politiques et mettre en place un système de financement occulte en faveur des républicains et leurs alliés.Nine days after he was sworn in, Bush launched his social program, the Faith-Based Initiatives (FBI, a major component of his “compassionate conservatism.” The FBI constituted a break with the Reagan monetarist tradition, even if they are motivated by the withdrawal of the State and the reduction of the social budget. 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.

  20. Evaluation of two polyimides and of an improved liner retention design for self-lubricating bushings

    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.

    This paper describes two process routes with focus on the die forging of coaxial hybrid workpieces. Using the example of two multi-material demonstrators, a bevel gear and a bearing bushing, two fundamental principles of hybrid-forged components will be presented. A cost-effective construction is realized for the bevel gear by means of a high-strength steel combined with a low-cost steel in the areas where high strength is not required. In contrast, the bearing bushing consisting of a steel-aluminium combination offers new potentials in terms of lightweight construction, saving component weight while featuring equal durability. In addition, forging tooling systems and tailored heating strategies for both demonstrators are presented and discussed.

    Bearing bush is a key part of diesel engine, and its performance directly influences the life of whole machine. Several manufacturing technologies of bearing bush such as centrifugal casting, sintering, electroplating and magnetron sputtering have been overviewed. Their bond strength, porosity, production efficient, layer thickness, frictional coefficient and corresponding materials analyzed and compared. Results show that the porosity and oxidation of sintering and centrifugal casting are higher than that of other two methods. However, the production efficiency and coating thickness are better than that of electroplating and magnetron sputtering. Based on above comparisons and discussions, the improvements of all manufacturing technologies are suggested and supersonic cold spraying is suggested. It is proved that cold spraying technology is the best choice in the future with the developing of low frictional materials.

    Symeonakis, E.; Higginbottom, T.

    2014-11-01

    It is widely accepted that land degradation and desertification (LDD) are serious global threats to humans and the environment. Around a third of savannahs in Africa are affected by LDD processes that may lead to substantial declines in ecosystem functioning and services. Indirectly, LDD can be monitored using relevant indicators. The encroachment of woody plants into grasslands, and the subsequent conversion of savannahs and open woodlands into shrublands, has attracted a lot of attention over the last decades and has been identified as a potential indicator of LDD. Mapping bush encroachment over large areas can only effectively be done using Earth Observation (EO) data and techniques. However, the accurate assessment of large-scale savannah degradation through bush encroachment with satellite imagery remains a formidable task due to the fact that on the satellite data vegetation variability in response to highly variable rainfall patterns might obscure the underlying degradation processes. Here, we present a methodological framework for the monitoring of bush encroachment-related land degradation in a savannah environment in the Northwest Province of South Africa. We utilise multi-temporal Landsat TM and ETM+ (SLC-on) data from 1989 until 2009, mostly from the dry-season, and ancillary data in a GIS environment. We then use the machine learning classification approach of random forests to identify the extent of encroachment over the 20-year period. The results show that in the area of study, bush encroachment is as alarming as permanent vegetation loss. The classification of the year 2009 is validated yielding low commission and omission errors and high k-statistic values for the grasses and woody vegetation classes. Our approach is a step towards a rigorous and effective savannah degradation assessment.

  16. The Second Administration of George W. Bush and U.S.-Russia Relations

    Full Text Available This article is devoted to the analysis of changes in the U.S.-Russia relationships during the presidency of George W. Bush and to the detection of the origins of these changes. The attention is paid to conceptual foreign policy views of the most influential members of administration. The renewal of staff in U.S. administration was one of the important factors of toughening the Russian course of the American foreign policy. At the beginning of the second presidency of George Bush the ratio of forces in the American Congress changed. Opposition forces received the majority in the Congress. This circumstance became the other reason of change of the U.S.-Russia relationships. The bilateral relations during the specified period were complicated by aspiration of the USA to strengthen the influence on the territories of the Post-Soviet states. It caused discontent of Moscow. At the same time, some aspects of the Russian-Iranian nuclear cooperation caused criticism of Washington. The role of personal diplomacy is noted as a factor of forming bilateral relations. During the second term of the presidency of George W. Bush this factor didn't lose its value in comparison with the first term. The article gives the assessment of work of the Bush’s second administration at the Russian direction. The author notes the American focus on the strategy of “selective partnership” with Russia. The conclusion is drawn on George Bush's aspiration to preservation of balance in the U.S.-Russia relations under the conditions of increasing strains.

    Full Text Available Rose cultivation requires many inputs for satisfactory production, making the process expensive. Nowadays, alternative practices have been used for sustainable crop production. Green manure is an agricultural practice that aims to maintain or improve soil fertility, increasing its yielding capacity. The objective of this research was to evaluate the effect of green manure with legumes on the yield and quality of ‘Vegas’ roses. Grafted rose seedlings were cultivated in open field for 30 months. Legumes used as green manure and planted intercropped with rose bushes were forage peanut (Arachis pintoi and jack bean (Canavalia ensiformis. Pigeon pea (Cajanus cajan was grown in a separate area, cut, macerated, and applied in the rows between rose bushes every 3 months. Plants of control group received no green manure, only mineral fertilizer and cattle manure, as in all other treatments. The experimental design was randomized block with four treatments (three green manure species plus the control and seven replications. The highest yield and quality of flower stems in ‘Vegas’ occurred with addition of pigeon pea on the soil surface or chemically treated (control. Forage peanut and jack bean are not suitable for intercropping with ‘Vegas’ rose bushes due to possible nutrient and water competition.

    An examination of the mould and fungal metabolite pattern in melon and bush mango seeds locally produced in Nigeria was undertaken in order to understand the mycotoxicological risk posed to consumers of both of these important and commonly consumed soup thickeners. The variation in mycotoxin levels in graded categories of both foodstuffs were also determined. Aspergillus, Fusarium, Penicillium, Mucorales and Trichoderma were the recovered fungi from the foodstuffs with Aspergillus species dominating (melon=97.8%; bush mango=89.9%). Among the Aspergillus species identified Aspergillus section Flavi dominated (melon: 72%; bush mango: 57%) and A. flavus, A. parasiticus, A. parvisclerotigenus and A. tamarii were the recovered species. About 56% and 73% of the A. flavus isolates from melon and bush mango seed samples, respectively were aflatoxigenic. Thirty-four and 59 metabolites including notable mycotoxins were found in the melon and bush mango seeds respectively. Mean aflatoxin levels (μg/kg) in melon (aflatoxin B1 (AFB1)=37.5 and total aflatoxins=142) and bush mango seeds (AFB1=68.1 and total aflatoxins=61.7) were higher than other mycotoxins, suggesting potential higher exposure for consumer populations.

    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

    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.

    Full Text Available Production systems influence crops differently, mainly in terms of yield. However, there are few studies that have evaluated different bushing snap bean genotypes in different systems. Thus, this study aimed to evaluate the production components and yield of bushing snap beans in conventional and organic production systems. The experimental design was a randomized complete block, in a factorial 6 × 2 arrangement, corresponding to six genotypes and two production systems, with three replications. The genotypes Isla Manteiga Baixo®, Isla Macarrão Baixo®, Feltrin Vicenza Amarelo Baixo®, and Feltrin Macarrão Napoli®, UEL 1, and UEL 2 were submitted to the following determinations: days to flowering; plant height; medium number of pods per plant; average pod mass, length, and diameter; and yield of commercial pods. A joint analysis of variance was conducted by applying the F test, with mean comparison performed using the Tukey’s test (p < 0.05. Anthesis of the genotypes Feltrin Vicenza Amarelo Baixo, UEL 2, Isla Macarrão Baixo, and Feltrin Macarrão Napoli is anticipated in the conventional production system. The genotype UEL 2 shows higher precocity in anthesis within the conventional system. The genotypes Isla Manteiga Baixo and UEL 1 produce more pods per plant in the conventional system. In the organic system, the genotype Feltrin Macarrão Napoli produces double the number of pods per plant compared with Isla Manteiga Baixo. The organic system leads to greater plant height and average mass, length, and diameter of pods in relation to the conventional system. The commercial pod yield of bushing snap bean is not altered by differences in the production system or genotype.

  7. The Relationship Between Morphological Symmetry and Immune Response in Wild-Caught Adult Bush-Crickets

    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 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. © 2016 The Author(s).

    Full Text Available Ecosystem services are the benefits resulting from resources and processes in nature. Trees and stand densities constitute a significant element of the landscape (both in urban and rural areas and serve a number of ecosystem functions, forming an inherent part of each group of benefits singled out on the basis of the Millennium Ecosystem Assessment. In the thesis, selected ecosystem services of trees and stand densities were detailed - provisioning, regulatory, supporting and cultural functions. Diagnosis of services performed by trees and their valuation may contribute to taking increased care of them and protection during performing various investments, it is therefore appropriate to launch multifaceted ecological education to each person, particularly to those directly responsible for trees and bushes in towns and rural areas. In order to restrict construction stress to trees and bushes, environmental impact assessment has to be made as soon as the construction planning is being made (natural, cultural and landscape conditions should be provided additionally, it is advisable to conduct a dendrological inventory for planning purposes. Appropriate protection of trees and standing densities is also legally regulated by the Nature Conservation Act and the Construction Law. During the investment process, the trees and their settlement conditions should be adequately secured , so that it will not affect their viability. After completed investment, the condition of the tree stand should be monitored.

    Changes in autumn canopy structure of tea bushes between early-plucked (here after EP,yield was 421 kg/10a on Aug. 1st in 2005), late-plucked (LP, 827 kg/10a on Aug. 8th) and not-plucked(NP) of the third crop was investigated by a stratiform clip method. All canopies of three bushes were cut with every 2 cm layer by a self-rail-tracking tea plucker on Oct. 19th in 2005. The result of vertical distribution of canopy biomass showed that the third crop plucking caused a decrease in leaf weight and bud number at the upper layers of the autumn canopy, but caused an increase in their lower layers. Although leaf weight of EP was same as that of LP, Leaf area index of EP was smaller however leaf specific weight was larger than LP. An analysis of relationship between autumn skiffing positions and bud number of the canopy surface was performed in order to estimate influences of the third crop plucking on new shoot number of the next first crop. The result was follows; the bud number of EP and LP was larger than that of NP at a lower autumn skiffing position (4 cm upper above the second plucking position), while bud number of NP was larger than EP and LP at a higher autumn skiffing position (6 cm upper).

    Directory of Open Access Journals (Sweden)

    Gerald Friedman

    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

    Klaus-Gerhard Heller

    Full Text Available Insects of the order Orthoptera are well-known for their acoustic communication. The structures used for this purpose show a high diversity which obviously relates to differences in song parameters and to the physics of sound production. Here we describe song and morphology of the sound producing organs of a tropical bush-cricket, Ectomoptera nepicauda, from East Africa. It has a very unusual calling song consisting of frequency-modulated, pure-tone sounds in the high ultrasonic range of 80 to 120 kHz and produced by extremely fast wing movements. Concerning morphology, it represents the most extreme state in the degree of left-right fore-wing differentiation found among Orthoptera: the acoustic parts of the left fore-wing consist exclusively of the stridulatory file, comparable in function to the bow of a violin, while the right wing carries only the plectrum ( =  string and mirror ( =  soundbox.

From the mathematical point of view, the considered problem is reduced to the analysis of ordinary differential equations governing the change of velocities of the contacting bodies, and to the integral Volterra-type equation governing contact pressure behavior. In the case where tribological processes are neglected, thresholds of chaos are detected using bifurcation diagrams and Lyapunov exponents identification tools. In addition, analytical Mel'nikov's method is applied to predict chaos. It is shown, among the others, that tribological processes play a stabilizing role. The following theoretical background has been used in the analysis: perturbation methods, Mel'nikov's techniques 7,8, Laplace transformations, the theory of integral equations, and various variants of numerical analysis.

    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.

    Physical and chemical parameters of fresh berries from three southern high bush (ONeal, Sharp blue and Misty) blueberry cultivars grown in Huelva (Southwestern Spain) under two production systems were measured and evaluated. ANOVA applied to data yielded significant differences between production systems for mean fruit size and mean fruit fresh weight (P<0.05), although main effects on physical and chemical characteristics of fruit were due to cultivar. All three cultivars showed significantly different means (P<0.05) for fruit fresh weight, and all chemical characteristics. Stepwise discriminant analysis (SDA) for classification and identification of the cultivars based on physico-chemical properties of samples of fruits was performed. The model obtained gave high percentages of correct classification and prediction (81.1% and 78.4%, respectively). The variables with higher discriminating power were fruit titratable acidity, fruit size and fruit sugar content. (Author)

    We study the role of bush encroachment control for a farmer's income and income risk in a stochastic ecological-economic model of grazing management in semi-arid rangelands. In particular, we study debushing as an instrument of risk management that complements the choice of an adaptive grazing management strategy for that sake. We show that debushing, while being a good practice for increasing the mean pasture productivity and thus expected income, also increases the farmer's income risk. The optimal extent of debushing for a risk-averse farmer is thus determined from balancing the positive and negative consequences of debushing on intertemporal and stochastic farm income.

    Full Text Available For the die casting conditions of aluminium bronzes assumed based on the literature data, a thick-walled bush was cast, made of complex aluminium bronze (Cu-Al-Fe-Ni-Cr. After the cast was removed from the mould, cracks were observed inside it. In order to identify the stage in the technological production process at which, potentially, the formation of stresses damaging the continuity of the microstructure created in the cast was possible (hot cracking and/or cold cracking, a computer simulation was performed. The article presents the results of the computer simulation of the process of casting the material into the gravity die as well as solidifying and cooling of the cast in the shape of a thick-walled bush. The simulation was performed with the use of the MAGMA5 program and by application of the CuAl10Ni5,5Fe4,5 alloy from the MAGMA5 program database. The results were compared with the location of the defects identified in the actual cast. As a result of the simulation of the die-casting process of this bush, potential regions were identified where significant principal stresses accumulate, which can cause local hot and cold cracking. Until now, no research has been made of die-cast aluminium bronzes with a Cr addition. Correlating the results of the computer simulation validated by the analysis of the actual cast made it possible to clearly determine the critical regions in the cast exposed to cracking and point to the causes of its occurrence. Proposals of changes in the bush die casting process were elaborated, in order to avoid hot tearing and cold cracking. The article discusses the results of preliminary tests being a prologue to the optimization of the die-casting process parameters of complex aluminium bronze thick-walled bushs.

    The two stigma lobes of bush monkeyflower (Mimulus aurantiacus) close together rapidly in response to touch by a hummingbird pollinator and usually remain closed for the life of the flower, preventing further pollen receipt. Previous work showed that hummingbirds visiting bush monkeyflowers with closed stigmas export more than twice as much pollen to recipient flowers as birds visiting flowers with open stigmas. To investigate how stigma closure increases pollen export, we used videotape to examine the interaction between bird and flower. Hummingbirds altered their method of foraging in response to whether the stigma was open or closed. When stigmas were closed, birds most frequently entered flowers from above, relative to the long axis of the corolla tube, bringing the bill close to the ceiling of the corolla where anthers and stigma are positioned. However, birds were much more likely to enter corollas from below when stigmas were open, keeping the bill farther from the sex organs, and resulting in failure to contact open stigmas 33% of the time. Distance of the bill from the corolla-tube ceiling was associated with frequency of contact with anthers and, when contact was made, explained pollen export in a non-linear fashion. Morphometric analyses showed that smaller corolla openings promoted stigma contact, but corolla openings that were wide relative to their height produced increased contact with anthers. Changes in hummingbird foraging position and reduced pollen export when visiting flowers with open stigmas helps to explain the observation of permanent stigma closure, even when less than full seed set has been achieved.

  13. Frequency processing at consecutive levels in the auditory system of bush crickets (tettigoniidae).

    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. (c) 2010 Wiley-Liss, Inc.

    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.

    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 Low voltage winding leads cause local eddy current losses in top-plate of the transformer tank. In this paper, this loss component which also causes local hot spots is investigated. Top-plate design is modified using stainless steel non-magnetic material, around the low voltage bushing holes. Manufacturing issues and cost as well as power losses are considered as main criteria during modification study. Magnetic flux distributions and eddy current losses are analysed and compared for different designs. Comparisons are based on 3D finite element simulations and experimental studies. Obtained results show that, insertion of single I-shaped stainless steel plate reduces eddy current losses around low voltage bushing holes to nearly zero.

  1. Anisotropy in Alpedrete granite cutting (Rift, Grain and Hardway directions) and effect on bush hammered heritage ashlars

    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

    What gets measured gets managed. Funding of health services is substantially determined by operational activity and specific outcome indicators. In day-to-day clinical decision-making, surrogate markers, such as glycosylated haemoglobin and blood pressure, are commonly used to modify risks of 'hard' outcomes that include kidney failure, ischaemic cardiac events, stroke and all-cause mortality. In many settings, surrogates are all we have to go on. As a consequence, current health funding models heavily rely on surrogate-based key performance indicators [KPIs]. While surrogates are convenient and provide immediate information, there is an obligation to ensure that they are appropriate, reliable and validated in context. In contrast, hard outcomes, the real consequences of illness, are usually realised over an extended timeframe. Additionally, and for a host of reasons, hard endpoints have the greatest social, emotional and economic impact for people at the far end of the health system; those in rural and remote settings - 'in the bush' - especially Indigenous Australians. We propose a health service assessment approach that aligns short-term decision-making with patient-centred and longer term hard outcomes, one that takes into account community, cultural and environmental factors, especially remoteness. Communities should have a major say in determining what health indicators are measured and managed. © 2017 National Rural Health Alliance Inc.

    We studied the potential of the essential oil extract from the bush mint, Hyptis suaveolens, for use against mosquito biting under both laboratory and field conditions. In the laboratory, the repellency of various concentrations (1-6%) of the essential oil was assessed against Anopheles gambiae, based on a 15-min landing and biting on treated forearms of volunteers. In the laboratory, the percentage of mosquitoes landing on the forearm was 42, 33, 23, 23, 9, and 2 for 1%, 2%, 3%, 4%, 5%, and 6% essential oil concentration, respectively; and 92 and 91 for the solvent (isopropanol) and untreated control, respectively. The percentage of mosquitoes taking a blood meal was 22, 12, 13, 12, 5, and 3 for 1%, 2%, 3%, 4%, 5%, and 6% essential oil, respectively; and 52 and 51 for the solvent and control, respectively. In the field, the 6% essential oil repelled all mosquitoes immediately postapplication; this activity declined to 75% after 5 h. The repellent action of the 8% essential oil concentration was higher, 97% after 5 h. Based on these data, the essential oil of H. suaveolens appears to be a good candidate for use in the integrated management of mosquito vectors of disease.

    Because the viability of a population may depend on whether individuals can disperse, it is important for conservation planning to understand how landscape structure affects movement behavior. Some species occur in a wide range of landscapes differing greatly in structure, and the question arises of whether these species are particularly versatile in their dispersal or whether they are composed of genetically distinct populations adapted to contrasting landscapes. We performed a capture-mark-resight experiment to study movement patterns of the flightless bush cricket Pholidoptera griseoaptera (De Geer 1773) in two contrasting agricultural landscapes in France and Switzerland. The mean daily movement of P. griseoaptera was significantly higher in the landscape with patchily distributed habitat (Switzerland) than in the landscape with greater habitat connectivity (France). Net displacement rate did not differ between the two landscapes, which we attributed to the presence of more linear elements in the connected landscape, resulting in a more directed pattern of movement by P. griseoaptera. Significant differences in the movement patterns between landscapes with contrasting structure suggest important effects of landscape structure on movement and dispersal success. The possibility of varying dispersal ability within the same species needs to be studied in more detail because this may provide important information for sustainable landscape planning aimed at maintaining viable metapopulations, especially in formerly well-connected landscapes.

    Studies of Malacothamnus fasciculatus var. nesioticus were begun in 1995 to understand its distribution, reproductive biology and ecological requirements. After 100+ years of depredation by sheep, two known populations of fewer than 20 plants each survived in 1995. Molecular studies showed that each of the two populations was composed of 1–3 genets. During our study, two additional populations of similar size were discovered. Plants are self-compatible but require insect visitation to augment pollination. Based on seed set, viable embryos, and germination rates, we found no evidence for inbreeding depression. Bush mallow also reproduces vegetatively by rhizomes, the primary means of establishment and persistence in natural populations, and a key feature for maximizing recovery success. Ex situ observations and trial in situ outplantings suggested that supplemental watering was critical to initial survival. We developed a recovery strategy composed of four plots located at varying elevations and aspects. Each plot was enclosed to exclude feral pigs, which posed a continuing threat. Each plot was planted with twelve rooted plants derived from each of three natural populations. Plants were provided supplemental watering for four months. Survivorship after one year ranged from 46% to 91%. Significant differences in survivorship were observed relative to source of plants. After twelve months some plants were flowering and reproducing vegetatively.

    To determine the chemical compositions and evaluate the antimicrobial activity of bush tea (Athrixia phylicoides DC.), special tea (Monsonia burkeana) and synergy (combination of bush tea and special tea). Total polyphenols were determined using the methods reported by Singleton and Rossi (1965) and modified by Waterman and Mole (1994). Tannins were determined using vanillin HCL methods described by Prince et al. (1978). Total antioxidants were determined using the methods described by Awika et al. (2004). The micro dilution technique using 96-well micro-plates, as described by Eloff (1998) was used to obtain the minimum inhibition concentration (MIC) and minimum microbicidal concentration (MMC) values of the ethanol extracts against the microorganisms under study. The microbes strain used was Gram negative bacteria such as Escherichia coli, Klebsiella oxytoca, Proteus vulgaris, Serratia marcescens, Salmonella typhi, Klebsiella pneumonia; Gram positive bacteria such as Bacillus cereus, Staphylococcus aureus and a fungus Candida albicans. The results demonstrated that special tea contains significantly higher content of total polyphenols (8.34 mg/100 g) and total antioxidant (0.83 mg/100 g) as compared to bush tea [total polyphenols (6.41 mg/100g) and total antioxidant (0.63 mg/100g)] and combination of bush tea and special tea [total polyphenols (6.42 mg/100 g) and total antioxidant (0.64 mg/100 g)]. There was no significant difference in tannins between bush tea, special tea and synergy. The results of antimicrobial activity (MIC and MMC) demonstrated that the ethanol extracts of bush tea, special tea and synergy possessed antimicrobial activity against all microorganisms at different zones. The MIC of bush tea ranged from 1.56 to 12.50 mg/mL while the MMC ranged from 0.78 to 12.50 mg/mL. Special tea's MIC ranged from 0.39 to 12.50 mg/mL while the MMC ranged from 0.01 to 12.50 mg/mL. The MIC of synergy ranged from 3.13 to 12.50 mg/mL while the MMC ranged from 3

    This article describes a unique, remote, water safety-training program delivered to 11 remote Australian communities during 2006-2007. The program, known as 'Water Safety in the Bush', was developed by Combined Universities Centre for Rural Health in Geraldton Western Australia in consultation with the Commonwealth Government Department of Health and Ageing, and the Royal Life Saving Society of Australia. Drowning and near drowning are major causes of childhood death and injury in rural and remote Australia, making improved water safety awareness and skills a public health priority. Water Safety in the Bush employed a flexible, community development model to meet the special requirements of remote and isolated communities. The model had three elements: coordination by a local organisation; a water safety instruction program based on a Royal Life Saving Society of Australia curriculum adapted to meet local priorities; and strategies for sustainability. In the delivery of the program a total of 873 children and 219 adults received swimming and water safety instruction; 47 adults and older children received first-aid training; and 38 community members became AUSTAWIM (the Australian Council for the Teaching of Swimming and Water Safety) accredited instructors. Project evaluation showed parents and community organisations were very satisfied with the program which met a real need. Parents and instructors gave evidence of children's increased skills in water safety, swimming ability, life-saving and water confidence. Training programs with greater contact hours showed greater skill gains. Sustainability strategies included accreditation of local AUSTSWIM instructors, the erection of water safety signs, sourcing of continuing funding, and the introduction of water safety theory into the school curriculum. Flexibility was the major success factor. Within the parameters of minimum guidelines, communities were encouraged to choose the timing, venue and delivery mode of the

    On 7 February 2009, and the following days Southeast Australia was devastated by large bush fires, which burned an area of about 3000 km2. This event was extraordinary, because a large number of combustion products was transported into the uppermost troposphere and lower stratosphere within a few days. Various biomass burning products released by the fire were observed by the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on the ENVISAT satellite. We track the plume using MIPAS C2H2, HCN and HCOOH single-scan measurements on a day-to-day basis. The measurements are compared with a high-resolution model run of the Global Environmental Multiscale-Air Quality (GEM-AQ) model. Generally there is very good agreement between the spatial distribution of measured and modelled pollutants during the first two weeks after the outbreak of the fire even over intercontinental distances. Both MIPAS and GEM-AQ show a fast south-eastward transport of the pollutants to New Zealand within one day. During the following 3-4 days the plume was located north and eastward of New Zealand and centered at altitudes of 15 to 18 km. Thereafter its eastern part was transported eastward at altitudes of 15-16 km, followed by westward transport of its western part at somewhat higher altitudes. On 17 February the eastern part had reached Southern South America and on 20 February the South African west coast. On the latter day a second relic of the plume was observed moving eastward above the Southern Pacific, whereas the westward transported pollutants were located above Australia at altitudes of 18-20 km. First evidence for entry of the pollutants into the stratosphere was found in MIPAS data of 11 February, followed by larger amounts on 17 February and the days thereafter. Between 20 February and the first week of March the stratospheric pollutants above Australia were transported further westward over the Indian Ocean towards Southern Africa.

    Full Text Available The shape and, therefore, the architecture of the plant are dependent on genetic and environmental factors such as water supply. The architecture determines the visual quality, a key criterion underlying the decision to purchase an ornamental potted plant. The aim of this study was to analyze genotypic responses of eight rose bush cultivars to alternation of water restriction and re-watering periods, with soil water potential of -20kPa and -10 kPa respectively. Responses were evaluated at the architectural level through 3D digitalization using six architectural variables and at the physiological level by measuring stomatal conductance, water content, hormones (abscisic acid, auxin, cytokinins, jasmonic acid and salicylic acid, sugars (sucrose, fructose and glucose and proline. Highly significant genotype and watering effects were revealed for all the architectural variables measured, as well as genotype x watering interaction, with three distinct genotypic architectural responses to water restriction - weak, moderate and strong - represented by Hw336, ‘Baipome’ and ‘The Fairy’, respectively. The physiological analysis explained, at least in part, the more moderate architectural response of ‘Baipome’ compared to ‘The Fairy’, but not that of Hw336 which is an interspecific hybrid. Such physiological responses could be related to: (i the maintenance of the stimulation of budbreak and photosynthetic activity in ‘Baipome’ during water restriction periods due to a higher concentration in conjugated cytokinins (cCK and to a lower concentration in salicylic acid (SA; (ii a better resumption of budbreak during the re-watering periods due to a lower concentration in abscisic acid (ABA during this period. When associated with the six architectural descriptors, cCK, SA and ABA, which explained the genotypic differences in this study, could be used as selection criteria for breeding programs aimed at improving plant shape and tolerance to

    Effects of habitat fragmentation on genetic diversity vary among species. This may be attributed to the interacting effects of species traits and landscape structure. While widely distributed and abundant species are often considered less susceptible to fragmentation, this may be different if they are small sized and show limited dispersal. Under intensive land use, habitat fragmentation may reach thresholds at which gene flow among populations of small-sized and dispersal-limited species becomes disrupted. Here, we studied the genetic diversity of two abundant and widespread bush crickets along a gradient of habitat fragmentation in an agricultural landscape. We applied traditional (G(ST), θ) and recently developed (G'ST', D) estimators of genetic differentiation on microsatellite data from each of twelve populations of the grassland species Metrioptera roeselii and the forest-edge species Pholidoptera griseoaptera to identify thresholds of habitat fragmentation below which genetic population structure is affected. Whereas the grassland species exhibited a uniform genetic structuring (G(ST) = 0.020-0.033; D = 0.085-0.149) along the whole fragmentation gradient, the forest-edge species' genetic differentiation increased significantly from D habitat dropped below a threshold of 20% and its proximity decreased substantially at the landscape scale. The influence of fragmentation on genetic differentiation was qualitatively unaffected by the choice of estimators of genetic differentiation but quantitatively underestimated by the traditional estimators. These results indicate that even for widespread species in modern agricultural landscapes fragmentation thresholds exist at which gene flow among suitable habitat patches becomes restricted. © 2010 Blackwell Publishing Ltd.

  12. Effect of the electromagnetic force on the power-train vibration of the in-wheel motor driving system with rubber bushings

    2016-03-01

    Full Text Available For an in-wheel motor driving system with rubber bushings, the driving motor is integrated into the wheel. A magnet gap deformation of the motor will be inevitably caused by the road excitation, which will produce an unbalanced electromagnetic force and influence the power-train vibration. Furthermore, the rim is flexibly connected to the motor rotor by rubber bushings, and a strong coupling and nonlinear vibration of the power-train in all directions can be demonstrated under the electromagnetic excitations. Thus, a 14-degree-of-freedom coupling vibration model of the power-train is first developed for the in-wheel motor driving system with rubber bushings, including the bushing and bearing models. Then, the mathematical model is deduced using a Lagrangian approach. Finally, based on the model, a coupling vibration analysis is conducted under different electromagnetic force excitations. The results indicate that there are coupling vibration components in the torsional direction, except the one-time rotating frequency; however, in the bending direction, the vibration response includes a one-time rotating frequency component and an excitation frequency component of the electromagnetic force. Furthermore, the results indicate that the bushing plays an important role in reducing the power-train vibration, which has a positive effect on the improving vehicle dynamics.

    The extent of self-compatibility and reliance on pollinators for seed set are critical determinants of reproductive success in invasive plant species. Seed herbivores are commonly used as biocontrol agents but may also act as flower visitors, potentially resulting in pollination. However, such contrasting or potentially counterproductive interaction effects are rarely considered or evaluated for biological control programs. We investigated the breeding system and pollinators of Bitou Bush ( Chrysanthemoides monilifera ssp. rotundata ), an invasive species in Australia that has been the subject of biocontrol programs since 1987. We found the species to be obligate outcrossing in all six populations tested. From 150 video hours, we found 21 species of potential pollinators, including Mesoclanis polana , the Bitou Seedfly, native to South Africa and released in Australia as a biocontrol agent in 1996. Mesoclanis polana transferred pollen to stigmas and was the most common pollinator (52% of pollinator visits), followed by the syrphid fly Simosyrphus grandicornis (9%) and introduced honeybee, Apis mellifera (6.5%). Fruit-to-flower ratios ranged from 0.12 to 0.45 and were highest in the population with the greatest proportion of Mesoclanis polana visits. In an experimental trial, outside the naturalized range, the native bee Homalictus sphecodoides and the native syrphid Melangyna viridiceps were the primary pollinators, and fruit-to-flower ratios were 0.35, indicating that Bitou Bush would have ready pollinators if its range expanded inland. Synthesis . Invasive Bitou Bush requires pollinators, and this is effected by a range of generalist pollinators in eastern Australia including the Bitou Seedfly, introduced as a biocontrol agent, and the major pollinator detected in this study. Fruit-to-flower ratios were highest when the Bitou Seedfly was in high abundance. This study underscores the importance of evaluating the pollination biology of invasive species in their

    Full Text Available AISn8Pb2Si25Cu0.8Cr0.2(ASP is a new bush material with high performance, but its bad lasticity 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 recipitated 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.

    Animals use sound for communication, with high-amplitude signals being selected for attracting mates or deterring rivals. High amplitudes are attained by employing primary resonators in sound-producing structures to amplify the signal (e.g. avian syrinx). Some species actively exploit acoustic properties of natural structures to enhance signal transmission by using these as secondary resonators (e.g. tree-hole frogs). Male bush-crickets produce sound by tegminal stridulation and often use specialised wing areas as primary resonators. Interestingly, Acanthacara acuta , a Neotropical bush-cricket, exhibits an unusual pronotal inflation, forming a chamber covering the wings. It has been suggested that such pronotal chambers enhance amplitude and tuning of the signal by constituting a (secondary) Helmholtz resonator. If true, the intact system - when stimulated sympathetically with broadband sound - should show clear resonance around the song carrier frequency which should be largely independent of pronotum material, and change when the system is destroyed. Using laser Doppler vibrometry on living and preserved specimens, microcomputed tomography, 3D-printed models and finite element modelling, we show that the pronotal chamber not only functions as a Helmholtz resonator owing to its intact morphology but also resonates at frequencies of the calling song on itself, making song production a three-resonator system. © 2017.

De l’expulsion de tous les clandestins à leur amnistie, de l’abolition de toute couverture sociale pour les immigrés à son augmentation substantielle, toutes les solutions sont proposées et envisagées. Et les inquiétudes de ces vingt dernières années ne sont pas sans rappeler celles du premier congrès continental qui s’inquiétait du risque d’attirer des « indésirables » et de créer une classe d’« assistés » en promettant trop facilement la propriété de la terre aux immigrants.

Des chiffres circulent faisant état de quelques 12 millions d’immigrants sans papiers, dont 7 millions seraient employés aux États-Unis.

    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

    Full Text Available The purpose of bird song and the way in which it is delivered has been argued to be adapted mainly for territorial defense. We performed a field experiment with the combination of playbacks and a model to test how much song actually relates to increased territorial defense in the territorial tropical songbird, the Pied Bush Chat, during breeding season (Feb–May, 2015 at Haridwar, Himalayan Foothills, India. As expected, the results of the experiment indicated that song was the major cue used by territory holders to cope with rival intrusions. The song rate was particularly escalated during simulated territorial interactions when the model was presented with a playback song of conspecifics. Behaviors such as restlessness (perch change, the height of perch, and distance from the model appeared to be of relatively lesser importance. To our knowledge, no avian species from the Indian subcontinent has been studied to provide evidence that song can escalate aggressive response by a territory owner.

    A new cryptic species of bush frog Raorchestes honnametti sp. nov. is described from the south-eastern part of the Western Ghats, India. This newly described species belongs to the Charius clade and is morphologically similar to other clade members--R. charius and R. griet. Therefore, an integrative taxonomic approach based on molecular and bioacoustic analysis along with morphology was used to delimit the new species. Raorchestes honnametti sp. nov., is currently known only from Biligiri Rangaswamy Temple Tiger Reserve, a part of Biligiri Rangaswamy horst mountain range (a mountain formed due movement of two faults) formed during the Late Quaternary period (1.8-2.58 Ma). Discovery of cryptic species from a highly speciose and well-studied genus Raorchestes hints at the possible existence of several more cryptic species in this genus. We discuss the possible reasons for crypsis and emphasize the need for continued systematic surveys of amphibians across the Western Ghats.

    In many ways, leadership is a phenomenon that is ideally suited for new and inventive research methods. For researchers who seek to reliably study and systematically compare linguistically based elements of the leadership relationship, computerized content analysis has the potential to supplement, extend, and qualify existing leadership theory and practice. Through an examination of President Bush's rhetoric and the media coverage before and after the crisis of 9/11. the authors explore how elements of the President's speeches changed in response to the post-crisis environment. Using this example, the authors illustrate the process of computerized content analysis and many of its strengths and limitations, with the hope of facilitating future leadership research that uses this approach to explore important contextual and symbolic elements of the leadership relationship.

    Full Text Available This paper studied the impact of moisture on the correlated characteristics of the condenser bushings oil-paper insulation system. The oil-impregnated paper samples underwent accelerated thermal aging at 130 °C after preparation at different initial moisture contents (1%, 3%, 5% and 7%. All the samples were extracted periodically for the measurement of the moisture content, the degree of polymerization (DP and frequency domain dielectric spectroscopy (FDS. Next, the measurement results of samples were compared to the related research results of transformer oil-paper insulation, offering a theoretical basis of the parameter analysis. The obtained results show that the moisture fluctuation amplitude can reflect the different initial moisture contents of insulating paper and the mass ratio of oil and paper has little impact on the moisture content fluctuation pattern in oil-paper but has a great impact on moisture fluctuation amplitude; reduction of DP presents an accelerating trend with the increase of initial moisture content, and the aging rate of test samples is higher under low moisture content but lower under high moisture content compared to the insulation paper in transformers. Two obvious “deceleration zones” appeared in the dielectric spectrum with the decrease of frequency, and not only does the integral value of dielectric dissipation factor (tan δ reflect the aging degree, but it reflects the moisture content in solid insulation. These types of research in this paper can be applied to evaluate the condition of humidified insulation and the aging state of solid insulation for condenser bushings.

    Chrysanthemoides monilifera ssp rotundata (L) T Norl (Bitou bush) is a serious environmental weed along the southeast coast of Australia. The herbicide glyphosate is commonly used to control C monilifera on the New South Wales coastline, but there have been few studies examining the effects of this herbicide on invertebrate communities in the field, especially on sand dunes. Control and impact sites were selected in coastal hind dunes heavily infested with C monilifera, and the impact sites were sprayed with a 1:100 v/v dilution of glyphosate-isopropyl 360 g AE litre(-1) SL (Roundup Biactive). Leaf litter invertebrates were sampled before spraying and after spraying by collecting fixed areas of leaf litter in both the control and impact sites. Samples were sorted for particular invertebrates involved in leaf litter decomposition and some of their predators. This study did not identify any significant direct or indirect effects on leaf litter invertebrate abundance or community composition in the four months following herbicide application. The litter invertebrate assemblages were highly variable on a small spatial scale, with abiotic factors more strongly regulating leaf litter invertebrate numbers than glyphosate application. These results conflict with previous studies, indicating that the detrimental indirect effects herbicide application has on non-target litter invertebrates may depend upon the application rate, the vegetation community and structure and post-spray weather. 2004 Society of Chemical Industry.

    In southeastern South Africa sub-humid grasslands on abandoned soils are spontaneously being invaded by the exotic shrub Pteronia incana (Blue bush) originating from the semi-arid and arid Karoo region. This results eventually in soil loss and rill and gully erosion and consequently loss in agricultural production affecting the local rural economy. Degradation of soils is occurring following replacement of grassland by unpalatable shrubs and altering the spatial organization of the vegetation. This in consequence is changing the eco-hydrological response of the hillslopes leading to a dramatic increase of runoff and erosion. However the reason for this spontaneous vegetation replacement is not clear. Various explanations have been proposed and discussed such as overgrazing, vegetation cover and rainfall, drought or climatic change or exposition. The study presented aims at quantifying the observed changes in the plant and bare spot patterns and which may help us unraveling vegetation self organisation processes in relation to environmental disturbances. We analyzed high resolution low altitude images of vegetation patterns in combination with high resolution digital terrain model analysis. We applied this procedure for different patterns reflecting a time series covering the observed changing patterns. These reflect changing interactions between the (re-) organization of the plant patterns during the bushy invasion and incorporated the interaction between vegetation, water redistribution and soil properties. By doing so we may be able to unravel critical processes as indicated by changes in vegetation patterns that might enable us to mitigate degradation of dryland ecosystems.

    A Phoma sp. was isolated and characterized as endophytic and as a pathogen of Larrea tridentata (creosote bush) growing in the desert region of southern Utah, USA. This fungus produces a unique mixture of volatile organic compounds (VOCs), including a series of sesquiterpenoids, some alcohols and several reduced naphthalene derivatives. Trans-caryophyllene, a product in the fungal VOCs, was also noted in the VOCs of this pungent plant. The gases of Phoma sp. possess antifungal properties and is markedly similar to that of a methanolic extract of the host plant. Some of the test organisms with the greatest sensitivity to the Phoma sp. VOCs were Verticillium, Ceratocystis, Cercospora and Sclerotinia while those being the least sensitive were Trichoderma, Colletotrichum and Aspergillus. We discuss the possible involvement of VOC production by the fungus and its role in the biology/ecology of the fungus/plant/environmental relationship with implications for utilization as an energy source. © 2011 Federation of European Microbiological Societies.

    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.

    Human immunodeficiency virus type 2 (HIV-2) originated from simian immunodeficiency viruses (SIVs) that naturally infect sooty mangabeys (SMs; Cercocebus atys). In order to further investigate the relationship between HIV-2 and SIVsm, the SIV specific to the SM, we characterized seven new SIVsm strains from SMs sold in Sierra Leone markets as bush meat. The gag, pol, and env sequences showed that, while the viruses of all seven SMs belonged to the SIVsm-HIV-2 lineage, they were highly divergent viruses, in spite of the fact that most of the samples originated from the same geographical region. They clustered in three lineages, two of which have been previously reported. Two of the new SIVsm strains clustered differently in gag and env phylogenetic trees, suggesting SIVsm recombination that had occurred in the past. In spite of the fact that our study doubles the number of known SIVsm strains from wild SMs, none of the simian strains were close to the groups in which HIV-2 was epidemic (groups A and B).

    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.

    Bush frogs of the genus Raorchestes are distributed mainly in the Western Ghats Escarpment of Peninsular India. The inventory of species in this genus is incomplete and there is ambiguity in the systematic status of species recognized by morphological criteria. To address the dual problem of taxon sampling and systematic uncertainty in bush frogs, we used a large-scale spatial sampling design, explicitly incorporating the geographic and ecological heterogeneity of the Western Ghats. We then used a hierarchical multi-criteria approach by combining mitochondrial phylogeny, genetic distance, geographic range, morphology and advertisement call to delimit bush frog lineages. Our analyses revealed the existence of a large number of new lineages with varying levels of genetic divergence. Here, we provide diagnoses and descriptions for nine lineages that exhibit divergence across multiple axes. The discovery of new lineages that exhibit high divergence across wide ranges of elevation and across the major massifs highlights the large gaps in historical sampling. These discoveries underscore the significance of addressing inadequate knowledge of species distribution, namely the "Wallacean shortfall", in addressing the problem of taxon sampling and unknown diversity in tropical hotspots. A biogeographically informed sampling and analytical approach was critical in detecting and delineating lineages in a consistent manner across the genus. Through increased taxon sampling, we were also able to discern a number of well-supported sub-clades that were either unresolved or absent in earlier phylogenetic reconstructions and identify a number of shallow divergent lineages which require further examination for assessment of their taxonomic status.

    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.

    Full Text Available The development of conservation strategies to mitigate the impact of invasive species requires knowledge of the species ecology and distribution. This is, however, often lacking as collecting biological data may be both time-consuming and resource intensive. 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

    Full Text Available A new, morphologically cryptic species of phaneropterine bush-crickets is described from the grasslands of the Romanian Eastern Carpathians. Despite the morphological and acoustic similarities with the recently described Isophya nagyi Szövényi, Puskás & Orci, I. bucovinensis sp. n. is characterized by a peculiar male calling song, with faster syllable repetition rate (160–220 syllables per minute, at 22–27°C and less complex syllable structure (composed of only two elements instead of three observable in I. nagyi. The morphological description of the new species is supplemented with an oscillographic and spectrographic analysis of the male calling song and male–female pair-forming acoustic duet. An acoustic signal-based identification key is provided for all the presently known species of the Isophya camptoxypha species group, including the new species.

    Invasive plant management is often justified in terms of conservation goals, yet progress is rarely assessed against these broader goals, instead focussing on short-term reductions of the invader as a measure of success. Key questions commonly remain unanswered including whether invader removal reverses invader impacts and whether management itself has negative ecosystem impacts. We addressed these knowledge gaps using a seven year experimental investigation of Bitou Bush, Chrysanthemoides monilifera subsp. rotundata. Our case study took advantage of the realities of applied management interventions for Bitou Bush to assess whether it is a driver or passenger of environmental change, and quantified conservation benefits relative to management costs of different treatment regimes. Among treatments examined, spraying with herbicide followed by burning and subsequent re-spraying (spray-fire-spray) proved the most effective for reducing the number of individuals and cover of Bitou Bush. Other treatment regimes (e.g. fire followed by spraying, or two fires in succession) were less effective or even exacerbated Bitou Bush invasion. The spray-fire-spray regime did not increase susceptibility of treated areas to re-invasion by Bitou Bush or other exotic species. This regime significantly reduced plant species richness and cover, but these effects were short-lived. The spray-fire-spray regime was the most cost-effective approach to controlling a highly invasive species and facilitating restoration of native plant species richness to levels characteristic of uninvaded sites. We provide a decision tree to guide management, where recommended actions depend on the outcome of post-treatment monitoring and performance against objectives. Critical to success is avoiding partial treatments and treatment sequences that may exacerbate invasive species impacts. We also show the value of taking advantage of unplanned events, such as wildfires, to achieve management objectives at

    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.

  19. Les relations économiques États-Unis / Amérique latine pendant les années Bush : la nouvelle donne Economic Relations between the United States and Latin America in the Bush Years: Changing Course

    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 Small additions of Cr, Mo and W to aluminium-iron-nickel bronze are mostly located in phases κi (i=II; III; IV,and next in phase α (in the matrix and phase γ2. They raise the temperature of the phase transformations in aluminium bronzes as well as the casts’ abrasive and adhesive wear resistance. The paper presents a selection of feeding elements and thermal treatment times which guarantees structure stability, for a cast of a massive bush working at an elevated temperature (650-750°C made by means of the lost foam technology out of composite aluminium bronze. So far, there have been no analyses of the phenomena characteristic to the examined bronze which accompany the process of its solidification during gasification of the EPS pattern. There are also no guidelines for designing risers and steel internal chill for casts made of this bronze. The work identifies the type and location of the existing defects in the mould’s cast. It also proposes a solution to the manner of its feeding and cooling which compensates the significant volume contraction of bronze and effectively removes the formed gases from the area of mould solidification. Another important aspect of the performed research was establishing the duration time of bronze annealing at the temperature of 750°C which guarantees stabilization of the changes in the bronze microstructure - stabilization of the changes in the bronze HB hardness.

    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.

    The ethanolic extracts of the orange peel (Citrus sinensis) and bush tea leaves (Hyptis suaveolens) were compared for their toxicity effect on the larvae of the yellow fever mosquito Aedes aegypti collected from disused tyres beside College of Natural Sciences building University of Agriculture, Abeokuta, Nigeria. Eight graded concentrations, 0.9ppm, 0.8ppm, 0.7ppm, 0.6ppm, 0.5ppm, 0.4ppm, 0.3ppm and 0.2ppm of both plant extracts were tested on the larvae. The mean lethal dose LD10, was 0.15 ppm for C. sinensis, 0.01 for H. suaveolens, while LD50 for C. sinensis was 0.4ppm, H. suaveolens 0.60ppm and LD90 for C. sinensis was 0.9ppm and H. suaveolens was 1.45ppm. LD10 for the control 0.65ppm, LD50 0.9ppm and LD90 2.0 ppm. The extract of C. sinensis peel caused higher mortality rate at concentrations 0.8ppm (95%) and 0.3ppm (90%) of the larvae while the extract of H. suaveolens caused high mortality rate on the larvae at concentrations of 0.9ppm (80%) and 0.3ppm (80%). Significant differences were observed between untreated and treated larvae (exposed to either of the extract) at the various concentrations (P< 0.05).

    2010-12-01

    Bush Physics for the 21st Century brings physics that is engaging to modern youth, and mathematically rigorous, to high school and college students in the remote and often road-less villages of Alaska where the opportunity to take a physics course has been nearly nonexistent. The primary goal of the course is to prepare rural (predominantly Alaska Native) students for success in university science and engineering degree programs and ultimately STEM careers. The course is delivered via video conference and web based electronic blackboard tailored to the needs of remote students. Kinetic, practical and culturally relevant place-based examples from traditional and modern northern life are used to engage students, and a rigorous and mathematical focus is stressed to strengthen problem solving skills. Simple hands-on-lab experiment kits are shipped to the students. In addition students conduct a Collaborative Research Experiment where they coordinate times of sun angle measurements with teams in other villages to determine their latitude and longitude as well as an estimate of the circumference of the earth. Connecting abstract mathematical symbols and equations to real physical objects and problems is one of the most difficult things to master in physics. We introduce Inuktitut symbols to complement the traditional Greek symbols in equations to strengthen the visual/conceptual connection with symbol and encourage an indigenous connection to the physical concepts. Results and observations from the first three pilot semesters (spring 2008, 2009 and 2010) will be presented.

    Remote sensing digital image analysis has been applied to monitor land clearing and degradation processes on a plateau covered by tiger bush near Niamey in South West Niger, where signs of severe landscape degradation due to fuelwood supply have been observed in the last decades. A MODIS NDVI dataset (2000-2015) and five LANDSAT images (1986-2012) were used to identify spatial and temporal dynamics and to emphasize areas of greater degradation. The study indicates that the land clearing found by previous investigations in the second part of the 20th century is still ongoing, with a decreasing trend of MODIS NDVI values recorded in the period 2000-2015. This trend appeared to be linked to an increase in bare soil areas that was demonstrated by analysis of LANDSAT SAVI images. The investigation also indicated that rates of degradation are stronger in more deteriorated areas like those located nearer Niamey; degradation patterns also tend to increase from the inner areas to the edges of the plateau. These results attest to the urgency to develop effective environmental preservation policies and find alternative solutions for domestic energy supply.

    Bush Physics for the 21st Century brings physics that is culturally connected, engaging to modern youth, and mathematically rigorous, to high school and college students in the remote and often road-less villages of Alaska. The primary goal of the course is to prepare rural (predominantly Alaska Native) students for success in university science and engineering degree programs and ultimately STEM careers. The course is currently delivered via video conference and web based electronic blackboard tailored to the needs of remote students. Practical, culturally relevant kinetic examples from traditional and modern northern life are used to engage students, and a rigorous and mathematical focus is stressed to strengthen problem solving skills. Simple hands-on-lab experiments are delivered to the students with the exercises completed on-line. In addition, students are teamed and required to perform a much more involved experimental study with the results presented by teams at the conclusion of the course. Connecting abstract mathematical symbols and equations to real physical objects and problems is one of the most difficult things to master in physics. Greek symbols are traditionally used in equations, however, to strengthen the visual/conceptual connection with symbol and encourage an indigenous connection to the concepts we have introduced Inuktitut symbols to complement the traditional Greek symbols. Results and observations from the first two pilot semesters (spring 2008 and 2009) will be presented.

  6. Boumediene v. Bush and the extraterritorial reach of the U.S. Constitution
    A step towards judicial cosmopolitanism?

    2008-12-01

    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.

  7. THE KEY ASPECTS OF NEOCONSERVATIVE INFLUENCE ON THE U.S. FOREIGN AND DEFENSE POLICY DURING THE FIRST G.W. BUSH ADMINISTRATION

    Full Text Available Neoconservative political ideology has influenced U.S. foreign and defense policy in various ways. During President G. W. Bush‘s first administration, addressed here, neoconservatives embedded in the Administration exercised a key influence on the President and his foreign policy decisions. Since the President is the key foreign and defense policy decision maker in the U.S.A., the influence of the neoconservatives in this field was very significant. To support the main thesis of the paper, an analysis of the content of neoconservative policy papers was made, and statements representing policy goals of neoconservatives were identified. It was concluded that the foreign and defense policy of the Bush administration was influenced by neoconservative political ideology, but the neoconservatives and hard-line realists who actively participated in decision-making processes diverged significantly from the political philosophy and advice of the ‗original‘ neoconservatives. They used elements of neoconservative ideology, considered useful for implication of their policy, particularly towards the Middle East and especially towards Iraq. Therefore, the practical (geo political reasoning of the decision-makers within the Administration clouded the declared theoretical base of their policy as well as the neoconservative values they claimed to support

  8. 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.

    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}.

    The study reported here investigated capacity of Atriplex lentiformis (Torr.) S. Wats. (Quail bush), Atriplex X aptera A. Nels. (pro sp.) (Wytana four-wing saltbush), and Hordeum marinum Huds. (seaside barley) to produce biomass and crude protein and take up cations when irrigated with moderately saline-sodic water, in the presence of a shallow water table. Water tables were established at 0.38, 0.76, and 1.14m below the surface in sand-filled columns. The columns were then planted to the study species. Study plants were irrigated for 224 days; irrigation water was supplied every 7 days equal to water lost to evapotranspiration (ET) plus 100mL (the volume of water removed in the most previous soil solution sampling). Water representing one of two irrigation sources was used: Powder River (PR) or coalbed natural gas (CBNG) wastewater. Biomass production did not differ significantly between water quality treatments but did differ significantly among species and water table depth within species. Averaged across water quality treatments, Hordeum marinum produced 79% more biomass than A. lentiformis and 122% more biomass than Atriplex X aptera, but contained only 11% crude protein compared to 16% crude protein in A. lentiformis and 14% crude protein in Atriplex X aptera. Atriplex spp. grown in columns with the water table at 0.38m depth produced more biomass, took up less calcium on a percentage basis, and took up more sodium on a percentage basis than when grown with the water table at a deeper depth. Uptake of cations by Atriplex lentiformis was approximately twice the uptake of cations by Atriplex X aptera and three times that of H. marinum. After 224 days of irrigation, crop growth, and cation uptake, followed by biomass harvest, EC and SAR of shallow groundwater in columns planted to A. lentiformis were less than EC and SAR of shallow ground water in columns planted to either of the other species.

    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.

    We construct a linear kinetic model of hydrate crystallization from a gas stream. We use this model to predict the fraction of gas that crystallizes as hydrate in the subsurface of Bush Hill, and the depth profile of subsurface hydrate accumulation. This is possible because the Bush Hill vent is fed by reservoir gas from the nearby Jolliet field whose composition is known. On the average, ˜9% of the vent gas is precipitated as hydrate in the subsurface. Although other explanations are possible, the observed vent gas compositions and the greater range of hydrate gas compositions are consistent with a single source gas whose venting rate varies by a factor of at least 3 over periods of a few years or less. The predicted depth profile of hydrate accumulation and the hydrate content of the Bush Hill mound suggest that between ˜1.1 × 109 and 2.8 × 109 m3 (STP) of gas may have accumulated as hydrate between the seafloor and ˜614-m depth. For the radiometrically and geologically suggested system age of 10,000 years, the time average venting rate is ˜106 m3/yr (0.7 × 106 kg/yr). If distributed evenly across the 600 m diameter mound, as suggested by echo sounder images, the methane flux is >3.2 kg/m2 yr. This is >103 times that inferred for hydrates associated with bottom-simulating seismic reflectors. The subsurface hydrate accumulation and the cumulative methane venting are related. We show how both may be estimated from measurements of vent gas composition, bottom water temperature, and geothermal gradient.

    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

Los escasos logros alcanzados no serán obstáculo para que Joseph S. Tulchin muestre un moderado optimismo por el desarrollo de la Iniciativa y los desafíos que le aguardan en los años próximos. Tras contextualizarla en el marco histórico del final de la guerra fría y del comienzo del desenvolvimiento a nivel global de las políticas económicas neoliberales, se pasa revista a los problemas por los que ha pasado la idea original en el interior de Estados Unidos y el entusiasmo con que fue acogida en América Latina. En este contexto uno de los primeros "tests" que pondrán a prueba el avance real de la Iniciativa para las Américas, será, sin lugar a dudas, la firma del Tratado de Libre Comercio (NAFTA con México.ABSTRACT: The author of this article tackles the analysis of the Enterprise for the Americas Initiative (EA1 two years after the White House spokesmen threw the idea. Scarce results achieved, won't be obstacle for Joseph S. Tulchin when he proves a moderate optimism with the development of the EAI and the coming challenges in the years ahead. After pointing the context out the EAI in the end of the Cold War and the evolution of neoliberal economics policies frame, he reviews difficulties to implement the original idea incide the United States and the enthusiastic reaction in Latin America. In this context, one of the first facts that will put the EAI real advance to the test, shall be without no doubt, the Free Trade Treaty(NAFTA signing with Mexico.

    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.

    PS304 is a high temperature solid lubricant coating comprised of a nickel-chrome binder, chrome oxide hardener, barium-calcium fluoride high temperature lubricant, and silver as the low temperature lubricant. This coating is used to lubricate Oil-Free Foil Air Bearings as they experience friction and wear during start up and shut down. The coating deposition process begins with undercutting the shaft. This area is then sandblasted to provide a rough surface for the coating to adhere to. The coating powder is then sent through the plasma spray gun and a reasonably thick layer is applied to the undercut area of the shaft. The coating is then ground down even with the surface of the shaft and gets a nice polished finish. The foil air bearings use the solid lubricant, as mentioned above, during start up and shut down. During normal operating conditions, generally above 2000RPM, the bearings utilize air as their lubricant. Foil air bearings are comprised of a thin top foil and a corrugated bump foil. They have an interference fit with the shaft before operation. As the air gets "trapped" between the top foil and the shaft, it presses the top foil against the bump foil, in turn compressing the bumps. As the bumps compress, it allows for the air to separate the top foil from the shaft, therefore, utilizing the trapped air as its lubricant.

  19. Seeing Roses in the Thorn Bush: Sexual Assault Survivors' Perceptions of Social Reactions.

    Science.gov (United States)

    Dworkin, Emily R; Newton, Emily; Allen, Nicole E

    2018-01-01

    After sexual assault, survivors often reach to others for support and receive a range of reactions. Although these reactions have been characterized by researchers as positive (e.g., emotional support) or negative (e.g., victim blaming), survivors vary in their perceptions in ways that do not always match this framework. The goal of this research was to examine the degree to which designations of reactions as "positive" or "negative" fits across types of reactions and explain instances of mismatch between these designations and survivors' perceptions. We conducted a qualitative analysis of interviews with 26 survivors of sexual assault to identify themes in their perceptions of social reactions. Although social reactions were generally perceived in a manner that matched researcher categorizations, there was significant variation. Perceptions could be characterized in terms of whether the reaction felt comfortable/soothing, consistent with survivors' needs/hopes/expectations, and helpful in the long term. The closeness of survivors' relationships with responders, the degree to which they were impacted by the assault, and the presence of other social reactions explained variation from researcher designations of reaction types. This study clarifies the considerations that survivors make when evaluating social reactions and what accounts for discrepant perceptions of these reactions; in particular, they highlight that there is no "one size fits all" reaction to survivors of sexual assault and the context in which reactions occur may affect how they are seen.

  8. Sustainable remote Australian transport for living on country and going out bush

    Directory of Open Access Journals (Sweden)

    Bruno Spandonide

    2017-06-01

    Full Text Available Both the domestic and international academic literature’s analysis of links between transport and wellbeing focuses mainly on urban settings and vulnerable population groups including older people, people with health issues, socio-economically disadvantaged people, or people undergoing more frequent extreme climatic events. While the relationship between remote Australians wellbeing and travelling activities is evident, its complexity still remains an under-researched topic. This is paradoxical when considering that extreme distances, high supply chain costs, limited access to services and to economic participation are well recognised obstacles for sustaining vibrant remote Australian communities. The latest accessibility-driven technological innovations in both the digital and the sharing economies are highly topical in transport projects in urban agglomerations but still a distant reality for remote Australia. There is a need for researching an appropriateness framework of such technologies because of the strong relevance of the multiple outcomes in terms of wellbeing that some of these innovations provide. Furthermore what defines a good quality of life can sometimes be very similar and other times greatly differ between remote and urban contexts. In the light of some recent transport and mobility research this paper analyses the potential connections between more appropriate transport innovations and increasingly resilient remote communities.

  10. 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 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.

  19. Floral scent composition predicts bee pollination system in five butterfly bush (Buddleja, Scrophulariaceae) species.

    2015-01-01

    Traditionally, plant-pollinator interactions have been interpreted as pollination syndrome. However, the validity of pollination syndrome has been widely doubted in modern studies of pollination ecology. The pollination ecology of five Asian Buddleja species, B. asiatica, B. crispa, B. forrestii, B. macrostachya and B. myriantha, in the Sino-Himalayan region in Asia, flowering in different local seasons, with scented inflorescences were investigated during 2011 and 2012. These five species exhibited diverse floral traits, with narrow and long corolla tubes and concealed nectar. According to their floral morphology, larger bees and Lepidoptera were expected to be the major pollinators. However, field observations showed that only larger bees (honeybee/bumblebee) were the primary pollinators, ranging from 77.95% to 97.90% of total visits. In this study, floral scents of each species were also analysed using coupled gas chromatography and mass spectrometry (GC-MS). Although the five Buddleja species emitted differentiated floral scent compositions, our results showed that floral scents of the five species are dominated by substances that can serve as attractive signals to bees, including species-specific scent compounds and principal compounds with larger relative amounts. This suggests that floral scent compositions are closely associated with the principal pollinator assemblages in these five species. Therefore, we conclude that floral scent compositions rather than floral morphology traits should be used to interpret plant-pollinator interactions in these Asian Buddleja species. © 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.

    Full Text Available The present study focused on the evolution of the karyotype in four genera of the tribe Pholidopterini: Eupholidoptera Mařan, 1953, Parapholidoptera Mařan, 1953, Pholidoptera Wesmaël, 1838, Uvarovistia Mařan, 1953. Chromosomes were analyzed using fluorescence in situ hybridization (FISH with 18S rDNA and (TTAGGn telomeric probes, and classical techniques, such as C-banding, silver impregnation and fluorochrome DAPI/CMA3 staining. Most species retained the ancestral diploid chromosome number 2n = 31 (male or 32 (female, while some of the taxa, especially a group of species within genus Pholidoptera, evolved a reduced chromosome number 2n = 29. All species show the same sex determination system X0/XX. In some taxa, a pericentric inversion has changed the morphology of the ancestral acrocentric X chromosome to the biarmed X. The rDNA loci coincided with active NORs and C-band/CG-rich segments. A comparison of the location of the single rDNA/NOR in the genus Pholidoptera suggests that reduced chromosome number results from Robertsonian translocation between two pairs of autosomes, one carrying the rDNA/NOR. The results constitute a step towards better understanding of the chromosomal reorganization and evolution within the tribe Phaneropterini and the whole subfamily Tettigoniinae.

    Raeini-Sarjaz, Mahmoud; Chalavi, Vida

    2008-11-01

    Pulvinus activity of Phaseolus species in response to environmental stimuli plays an essential role in heliotropic leaf movement. The aims of this study were to monitor the continuous daily pulvinus movement and pulvinus temperature, and to evaluate the effects of leaf movements, on a hot day, on instantaneous leaf water-use efficiency (WUEi), leaf gas exchange, and leaf temperature. Potted plants of Phaseolus vulgaris L. var. Provider were grown in Chicot sandy loam soil under well-watered conditions in a greenhouse. When the second trifoliate leaf was completely extended, one plant was selected to measure pulvinus movement using a beta-ray gauging (BRG) meter with a point source of thallium-204 (204Tl). Leaf gas exchange measurements took place on similar leaflets of three plants at an air temperature interval of 33-42°C by a steady-state LI-6200 photosynthesis system. A copper-constantan thermocouple was used to monitor pulvinus temperature. Pulvinus bending followed the daily diurnal rhythm. Significant correlations were found between the leaf-incident angle and the stomatal conductance ( R 2 = 0.54; P photosynthesis rate ( R 2 = 0.84; P light intensity and air temperature and influenced leaf gas exchange.

    To our knowledge, this paper describes the first successful attempt to calculate large-scale temporal trends of insect populations on the basis of an automatic identification process of acoustic data. We argue that acoustic monitoring along roads, coupled with the automatic recognition of species sounds, offers several advantages for assessing Orthoptera biodiversity response to global changes and environmental measures.

  1. Effect of Bacterial Distribution and Activity on Conjugal Gene Transfer on the Phylloplane of the Bush Bean (Phaseolus vulgaris)

    1998-01-01

    Conjugal plasmid transfer was examined on the phylloplane of bean (Phaseolus vulgaris) and related to the spatial distribution pattern and metabolic activity of the bacteria. The donor (Pseudomonas putida KT2442) harbored a derivative of the TOL plasmid, which conferred kanamycin resistance and had the gfp gene inserted downstream of a lac promoter. A chromosomal insertion of lacIq prevented expression of the gfp gene. The recipient (P. putida KT2440) had a chromosomal tetracycline resistance marker. Thus, transconjugants could be enumerated by plating and visualized in situ as green fluorescent cells. Sterile bean seedlings were inoculated with donors and recipients at densities of approximately 105 cells per cm2. To manipulate the density and metabolic activity (measured by incorporation of [3H]leucine) of the inoculated bacteria, plants were grown at various relative humidities (RH). At 100% RH, the transconjugants reached a density of 3 × 103 CFU/cm2, corresponding to about one-third of the recipient population. At 25% RH, numbers of transconjugants were below the detection limit. Immediately after inoculation onto the leaves, the per-cell metabolic activity of the inocula increased by up to eight times (100% RH), followed by a decrease to the initial level after 96 h. The metabolic activity of the bacteria was not rate limiting for conjugation, and no correlation between the two parameters was observed. Apparently, leaf exudates insured that the activity of the bacteria was above a threshold value for transfer to occur. Transconjugants were primarily observed in junctures between epidermal cells and in substomatal cavities. The distribution of the transconjugants was similar to the distribution of indigenous bacteria on nonsterile leaves. Compared to polycarbonate filters, with cell densities equal to the overall density on the leaves, transfer ratios on leaves were up to 30 times higher. Thus, aggregation of the bacteria into microhabitats on the phylloplane had a great stimulatory effect on transfer. PMID:9572970

    The past decade has brought substantial transition to South Africa. The introduction of democracy in 1994 has yielded important political and socioeconomic transformations affecting millions of people. Here, we explore the impact of institutional and structural changes on the availability and management of fuelwood, a key natural resource in rural South Africa. As in other developing regions, many households depend on natural resources for both sustenance and energy needs. Drawing on qualitative data from 32 interviews, our objective is to describe, from the perspective of the respondents, (1) resource scarcity, (2) the underlying causes of resource scarcity, (3) the role of traditional authority in managing resources, and (4) strategies used by community members in the face of resource scarcity. The results have important implications for the well-being of both social and natural systems in many transitional, rural developing societies. PMID:21909188

    Global health research into the relationship between health, economic inequalities, and globalization is necessary to address increasing health disparities in low income countries. Nicaragua has high levels of poverty and extreme poverty when compared with other Central and South American Countries. Photovoice and ethnographic research methods were used to explore health experiences of Creole women in Bluefields, Nicaragua and the intersections between culture, socioeconomic status, and gender. Twelve Creole women participants, ages 18-45. After initial focus groups, participants used disposable cameras to document health experiences. Follow-up interviews were conducted about the meaning of each photo. Participants then selected photos to be included in a city-wide photoshow. In initial focus groups, participants described great distress over changes they perceived in Creole culture and how these changes affect the health of the next generation. Participants related most of these changes to the economy and globalization. Photos taken were primarily of aspects of Creole culture, including household practices and traditional remedies from Creole culture. Findings on the relationships between culture, disease, and community-identified health risks in this minority population can help health care providers and public health policymakers develop and sustain culturally appropriate health interventions. © 2014 Wiley Periodicals, Inc.

    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.

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

    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. © 2015 The Authors.

    2016-01-18

    To examine the provision of oral health and oral health service in rural areas from the perspective of general practitioners working in communities without resident dentists. A qualitative approach using face-to-face, semi-structured interviews with 30 GPs from rural Queensland, Tasmania and South Australia, conducted between October 2013 and October 2014. Four major themes emerged from the interviews: rural oral health, managing oral health presentations, barriers to patients seeing a dentist, and improving oral health. Rural GPs saw patients with a range of oral health problems, including toothache, abscesses and trauma, and observed poor oral health in their communities. Some acknowledged that they were not confident when dealing with oral health problems; they typically provided short-term pain relief, prescriptions for antibiotics, and advised patients to see a dentist. Participants noted that rural patients may not see a dentist when advised to do so because symptoms had abated, oral health was regarded as a low priority, or the costs of travelling to and seeing a dentist discouraged them. The interviewees recommended building the capacity of GPs to better care for patients with oral health problems, establishing more effective communication and referral pathways between GPs and dentists, focusing on preventive dental care, and delivering dental services in more flexible and consistent ways that better meet the needs of the communities. Rural oral health could be improved by several approaches, including additional training for GPs in oral health care, primary prevention activities in communities, and improving the access to dental services.

    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.

    2017-08-01

    Full Text Available The productive activity of man results in contamination of the environment which causes substantial damage to ecosystems, upsetting their balance, species composition, etc. Within industrial areas, plants suffer significant harm. At the same time, plant organisms play an important role in optimization of the environment, performing sanitary-hygienic, landscaping and aesthetic functions. In this context, we investigated the influence of industrial contamination of air by fluorine, sulphur and nitrogen compounds on the activity of peroxidase and polyphenoloxidase in ten types of arboreal and shrub plants which differ in their resistance to air pollution. Our research was conducted on the basis of a full multivariate experiment with two levels of factors. Peroxidase activity was determined by a colorimetric method according to the duration of oxidization of benzidine. For determination of polyphenoloxidase activity we determined the duration of oxidization of p-phenilendiamin according to the change in optical density of the solution. Pollutants have a significant influence on activity of the investigated enzymes in the leaves of the plant species studied, which depends on the resistance of the plants to contamination, and also the composition and concentrations of pollutants. With resistant species (Ligustrum vulgare L., Quercus robur L., Lonicera tatarica L., Eleagnus angustifolia L., Philadelphus coronaria L. peroxidase activity either did not change or rose by 11.2–64.1% compared to the control, depending on the composition of pollutants, their concentrations and the duration of their activity. Polyphenoloxidase activity in these plants did not significantly change in most variants of the experiment, although high concentrations of pollutants resulted in suppression of the activity of this enzyme by 26.1–37.6%. In species with variable tolerance which did not experience damage, peroxidase function did not change. Species sensitive to pollutants (Sorbus aucuparia L., Fraxinus lanceolata Borkh were characterized by the significant decline in peroxidase and polyphenoloxidase activity, by 18.7–79.1% and 20.5–71.2% respectively, depending on the duration of action of the gases in all variants of the experiment. In species with variable tolerance (Aesculus hippocastanum L., Acer negundo L., Populus simonii Carriere the reaction to the pollutants was ambiguous in nature and depended on the presence of damage. If the leaves of these plants did not show visible damage (necrosis, then activity of the enzymes did not change. When there was damage to leaf laminae this index decreased in relation to control by 17.3–60.1% for peroxidase and 24.7–57.3% for polyphenoloxidase. Significant negative linear correlation was found between activity of antioxidant enzymes and damage to leaves of the investigated plants: the coefficients of correlation were –0.385 between peroxidase activity and damage and –0.130 between polyphenoloxidase activity and damage. The character of changes in peroxidase and polyphenoloxidase activity show that these enzymes play a considerable role in the detoxication of pollutants and that there is a reduction in their influence on metabolic processes of plant organisms.

    Full Text Available Raorchestes tuberohumerus (Kuramoto & Joshy, 2003 was described based on three male specimens and was diagnosed mainly based on the presence of tubercle on the humerus.  Here we describe the genetically confirmed female of the species and show that tubercle on the humeral bone is a sexually dimorphic character present only in males.  Further, based on current collection and literature review we studied the distribution of the species using niche based modelling. Using the distributional range and our observations on the threats to the habitat we propose that Raorchestes tuberohumerus, currently assessed as Data Deficient, can fall under the ‘Vulnerable’ category of IUCN Red List of Threatened Species.

    A considerable part of our lives is spent engaging in the entertaining worlds of fiction that are accessible through media such as books and television. Little is known, however, about how we are able to readily understand that fictional events are distinct from those occurring within our real world. The present functional imaging study explored the brain correlates underlying such abilities by having participants make judgments about the possibility of different scenarios involving either real or fictional characters being true, given the reality of our world. The processing of real and fictional scenarios activated a common set of regions including medial-temporal lobe structures. When the scenarios involved real people, brain regions associated with episodic memory retrieval and self-referential thinking, the anterior prefrontal cortex and the precuneus/posterior cingulate, were more active. In contrast, areas along the left lateral inferior frontal gyrus, associated with semantic memory retrieval, were implicated for scenarios with fictional characters. This implies that there is a fine distinction in the manner in which conceptual information concerning real persons in contrast to fictional characters is represented. In general terms, the findings suggest that fiction relative to reality tends to be represented in more factual terms, whereas our representations of reality relative to fiction are colored by personal subjectivity. What modulates our understanding of the relative difference between reality and fiction seems to be whether such character-type information is coded in self-relevant terms or not.

    Fusarium species are hyaline hyphomycetes widely distributed in nature and documented agents of both superficial and systemic infections in humans. In this paper, we report a darkly-pigmented and initially non-sporulating isolate in the Fusarium solani species complex (FSSC) causing a post-traumatic sporotrichoid infection in an otherwise healthy, male patient. Sequencing of multiple loci showed that the isolate represented an otherwise unknown lineage, possibly corresponding to a separate species, within the multi-species F. solani complex. In prolonged culture, the non-sporulating isolate produced revertant wild-type subcultures with typical Fusarium conidiation. This suggests that the original dense, dark, non-sporulating isolate was a host-adapted form selected in vivo for characters compatible with human pathogenicity. The production of such forms by Fusarium species is increasingly recognized now that sequencing has allowed the identification of highly atypical isolates. In vitro antifungal susceptibility of the isolate was investigated against seven conventional and two newly approved antifungal agents. The isolate showed in vitro resistance to amphotericin B, but appeared susceptible to itraconazole and terbinafine. A cure was ultimately achieved with combined terbinafine/itraconazole therapy with prolonged itraconazole follow-up therapy.

    Highbush blueberry (Vaccinium corymbosum L.) is an important crop grown throughout Florida. Currently, most blueberry growers use honey bees (Apis mellifera L.) to provide pollination services for highbush blueberries even though bumble bees (Bombus spp.) have been shown to be more efficient at pollinating blueberries on a per bee basis. In general, contribution of bumble bees to the pollination of commercial highbush blueberries in Florida is unknown. Herein, we determined if managed bumble bees could contribute to highbush blueberry pollination. There were four treatments in this study: two treatments of caged commercial bumble bee (Bombus impatiens Cresson) colonies (low and high weight hives), a treatment excluding all pollinators, and a final treatment which allowed all pollinators (managed and wild pollinators) in the area have access to the plot. All treatments were located within a highbush blueberry field containing two cultivars of blooming plants, 'Emerald' and 'Millennia', with each cage containing 16 mature blueberry plants. We gathered data on fruit set, berry weight, and number of seeds produced per berry. When pollinators were excluded, fruit set was significantly lower in both cultivars (58%). Berry weight was not significantly different among the treatments, and the number of seeds per berry did not show a clear response. This study emphasizes the importance of bumble bees as an effective pollinator of blueberries and the potential beneficial implications of the addition of bumble bees in commercial blueberry greenhouses or high tunnels. © The Authors 2017.

    The Northern Territory (NT) of Australia is a unique setting for training medical students. This learning environment is characterised by Aboriginal health and an emphasis on rural and remote primary care practice. For over a decade the NT Clinical School (NTCS) of Flinders University has been teaching undergraduate medical students in the NT. Community based medical education (CBME) has been demonstrated to be an effective method of learning medicine, particularly in rural settings. As a result, it is rapidly gaining popularity in Australia and other countries. The NTCS adopted this model some years ago with the implementation of its Rural Clinical School; however, urban models of CBME are much less well developed than those in rural areas. There is considerable pressure to better incorporate CBME into medical student teaching environment, particularly because of the projected massive increase in student numbers over the next few years. To date, the community setting of urban Darwin, the NT capital city, has not been well utilised for medical student training. In 2008, the NTCS enrolled its first cohort of students in a new hybrid CBME program based in urban Darwin. This report describes the process and challenges involved in development of the program, including justification for a hybrid model and the adaptation of a rural model to an urban setting. Relationships were established and formalised with key partners and stakeholders, including GPs and general practices, Aboriginal medical services, community based healthcare providers and other general practice and community organisations. Other significant issues included curriculum development and review, development of learning materials and the establishment of robust evaluation methods. Development of the CBME model in Darwin posed a number of key challenges. Although the experience of past rural programs was useful, a number of distinct differences were evident in the urban setting. Change leadership and inter-professional collaboration were key strengths in the implementation and ongoing evaluation of the program. The program will provide important information about medical student training in urban community settings, and help inform other clinical schools considering the adoption of similar models.

    Previous studies have focused on the treatment received by rural cancer patients and have not examined their diagnostic pathways as reasons for poorer outcomes in rural Australia. To compare and explore symptom appraisal and help-seeking behaviour in patients with breast, lung, prostate or colorectal cancer from rural Western Australia (WA). A mixed-methods study of people recently diagnosed with breast, lung, prostate or colorectal cancer from rural WA. The time from first symptom to diagnosis (i.e. total diagnostic interval, TDI) was calculated from interviews and medical records. Sixty-six participants were recruited (24 breast, 20 colorectal, 14 prostate and 8 lung cancer patients). There was a highly significant difference in time from symptom onset to seeking help between cancers (P = 0.006). Geometric mean symptom appraisal for colorectal cancer was significantly longer than that for breast and lung cancers [geometric mean differences: 2.58 (95% confidence interval, CI: 0.64-4.53), P = 0.01; 3.97 (1.63-6.30), P = 0.001, respectively]. There was a significant overall difference in arithmetic mean TDI (P = 0.046); breast cancer TDI was significantly shorter than colorectal or prostate cancer TDI [mean difference : 266.3 days (95% CI: 45.9-486.8), P = 0.019; 277.0 days, (32.1-521.9), P = 0.027, respectively]. These differences were explained by the nature and personal interpretation of symptoms, perceived as well as real problems of access to health care, optimism, stoicism, machismo, fear, embarrassment and competing demands. Longer symptom appraisal was observed for colorectal cancer. Participants defined core characteristics of rural Australians as optimism, stoicism and machismo. These features, as well as access to health care, contribute to later presentation of cancer.

    The effects of dietary inclusion of Cistus ladanifer L. (CL) and a vegetable oil blend were evaluated on growth performance,carcass and meat quality of fifty four lambs that were assigned to 9 diets, corresponding to 3 levels of CL(50, 100 and 200 g/kg DM) and 3 levels of oil inclusion (0, 40 and 80 g/kg DM). Treatments had no effects on growth rate. Oil depressed dry matter intake (P = 0.017), carcass muscle (P = 0.041) and increased (P = 0.016) kidney knob channel fat. Chemical and physical meat quality traits were not affected by treatments. Off-flavour perception was higher for 8% of oil (P b 0.001). The level of 100 g/kg DM of CL inclusion improved meat stability after 7 days of storage. Supplementation with linseed and soybean oils (2:1) was a good approach to improve meat nutritional value from feedlot lambs, increasing total n-3 PUFA.

    Phytomanagement of trace element-contaminated soils can reduce soil toxicity and restore soil ecological functions, including the soil gas exchange with the atmosphere. We studied the emission rate of the greenhouse gases (GHGs) CO2, CH4, and N2O; the potential CH4 oxidation; denitrification enzyme activity (DEA), and glucose mineralization of a Cu-contaminated soil amended with dolomitic limestone and compost, alone or in combination, after a 2-year phytomanagement with a mixed stand of Populus nigra, Salix viminalis, S. caprea, and Amorpha fruticosa. Soil microbial biomass and microbial community composition after analysis of the phospholipid fatty acids (PLFA) profile were determined. Phytomanagement significantly reduced Cu availability and soil toxicity, increased soil microbial biomass and glucose mineralization capacity, changed the composition of soil microbial communities, and increased the CO2 and N2O emission rates and DEA. Despite such increases, microbial communities were evolving toward less GHG emission per unit of microbial biomass than in untreated soils. Overall, the aided phytostabilization option would allow methanotrophic populations to establish in the remediated soils due to decreased soil toxicity and increased nutrient availability.

    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 m{sup 2} (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.

    Hyptis suaveolens (L) Poit and Boerhavia diffusa Linn are medicinal herbal plants commonly found in the tropics and sub-tropics. They are used to treat various conditions among them boils, dyslipidaemia, eczema, malaria, jaundice and gonorrhoea. Thus, the herbal medicinal extracts are now found as part of some commercial herbal formulations. There has not been adequate characterization of these medicinal herbs on their effects on drug metabolising enzymes. To investigate the effects of extracts of Hyptis suaveolens (HS) and Boerhavia diffusa (BD) on activity of drug metabolising enzymes, CYP1A2, CYP2D6 and CYP3A4, as well predict their potential for herb-drug interaction. A secondary aim was to identify constituent compounds such as polyphenolics, in the crude extract preparations of Hyptis suaveolens and Boerhavia diffusa and measure them for activity. CYP450 inhibition assays using recombinant CYP450 (rCYP) and fluorescence screening employing individual isozymes (CYP1A2, CYP2D6 and CYP3A4) were used to determine reversible- and time-dependent inhibition (TDI) profiles of extracts of Hyptis suaveolens and Boerhavia diffusa. Inhibition kinetic parameters, Ki and Kinact were also estimated. UPLC-MS employing a Synapt G2 (ESI negative) coupled to a PDA detector was used to identify polyphenolic compounds in crude extracts of Hyptis suaveolens and Boerhavia diffusa. The inhibitory potency of Hyptis suaveolens and Boerhavia diffusa extracts varied among the different enzymes, with CYP1A2 (3.68 ± 0.10µg/mL) being the least inhibited by HS compared to CYP2D6 (1.39 ± 0.01µg/mL) and CYP3A4 (2.36 ± 0.57µg/mL). BD was most potent on CYP3A4 (7.36 ± 0.94µg/mL) compared to both CYP2D6 (17.79 ± 1.02µg/mL) and CYP1A2 (9.48 ± 0.78µg/mL). Extracts of Hyptis suaveolens and Boerhavia diffusa exhibited TDIs on all CYPs. The most prominent phenolic candidates identified in both medicinal herbs using UPLC-MS analysis included caffeic acid, rutin, quercetin, citric acid, ferulic acid and gluconic acid. These phenolic compounds are thought to potentially give HS and BD their therapeutic effects and inhibitory characteristics affecting CYP450 activities. In vivo predictions showed the potential for HS and BD extracts to cause significant interactions if co-administered with other medications. The study reveals that crude aqueous extracts of HS and BD potentially inhibit drug metabolising isozymes CYP1A2, CYP2D6 and CYP3A4 in a reversible and time-dependent manner. Thus care should be taken when these extracts are co-administered with drugs that are substrates of CYP1A2, CYP2D6 and CYP3A4. Copyright © 2017 Elsevier B.V. All rights reserved.

    We herein describe a new colorful species of Polychrus with a conspicuous sexual dimorphism from the dry forest of the northern portion of Región de La Libertad, Peru. The new species differs from all other Polychrus species, in that this species has very small dorsal scales and thus a higher number of scales around midbody and in the middorsal line from behind the occipital scales to the level of the posterior edge of the thigh. Furthermore, we redescribe Polychrus peruvianus whose original description is short and lacks information on intraspecific variation and sexual dimorphism. Also, we add some information on intraspecific variation and ecology of Polychrus gutturosus. Finally, we synonymize Polychrus spurrelli Boulenger with Polychrus gutturosus.

  2. Influence of a Second Crop Plucking and Subsequent Trimming on Canopy Structure in Autumn and on the First Crop of Subsequent Year for Mature Tea (Camellia sinensis L.) Bush

    Science.gov (United States)

    Takayuki, Nakano

    I performed 3 experiments at Shizuoka Tea Experiment Station to study the influence of trimming after the plucking of a second crop on the canopy structure in autumn and on the first crop of the subsequent year. Almost all my data revealed that the trimming reduced the number of new shoots but increased the weight of 100 new shoots in the first crop of the subsequent year. However, low trimming after late plucking of a second crop with a large yield remarkably reduced the tea canopy biomass and the number of buds on the skiffing surface in autumn, and it often led to a low yield in the first crop of the subsequent year. An excessively high yield in the second crop and low trimming might induce poor reverse of shoot growth in summer. A combination of low trimming and high skiffing in autumn delayed the growth of new shoots and reduced the free amino acid concentrations in new shoots in the first crop of the subsequent year. These results can be extrapolated for the main temperate zone of Shizuoka Prefecture, Japan.

    1997-03-01

    Full Text Available Use of herbal remedies from medicinal plants (bush medicines was studied in 622 people with diabetes mellitus attending 17 government health centers on the island of Trinidad, Trinidad and Tobago. Bush medicines were used by 42% of patients surveyed and were used for diabetes by 24%. Bush medicine use was more frequent in Afro-Trinidadians and in those of mixed ethnicity than in Indo-Trinidadians, and was also more prevalent in those with lower educational attainment. Most patients using bush medicines (214/264, or 81% reported gathering the plants themselves, and 107/264 (41% took them more frequently than once a week. Patients taking bush medicines mentioned 103 different plants used in remedies. Among the 12 most frequently mentioned, caraili, aloes, olive-bush, and seed-under-leaf were preferentially used for diabetes. Vervine, chandilay, soursop, fever grass, and orange peel were preferentially used for other indications. Patients who reported burning or numbness in the feet or feelings of tiredness, weakness, giddiness, or dizziness used bush medicines for diabetes more frequently than did patients who reported a range of other diabetes-related symptoms. Insulin-treated patients were less frequent users of bush medicines. It is concluded that bush medicines are taken regularly by many patients with diabetes in Trinidad. Plants most frequently used as remedies for diabetes have recognized hypoglycemic activity. Patients' culture, educational background, type of symptoms, and formal medical treatment may also influence the selection and use of bush medicines.

    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.

    Full Text Available INTRODUÇÃO:A cicatrização do trato gastrintestinal é de grande importância na história da cirurgia, buscando-se tipos de fios e pontos apropriados e os diversos fatores que a influenciam. O uso de fitoterápicos como aceleradores da cicatrização tem sido feito por muitos anos sendo objetivo atual de pesquisas para a comprovação científica dessas propriedades terapêuticas. OBJETIVO: Avaliar o uso do extrato bruto de Jatropha gossypiifolia L. na cicatrização de gastrorrafias em ratos. MÉTODOS: Foram utilizados 40 ratos Wistar, machos, divididos em dois grupos de 20, denominados de grupos controle e Jatropha. Dez animais de cada grupo foram mortos no 3º dia pós-operatório e denominados subgrupos controle e Jatropha do 3º dia e os 10 restantes de cada grupo foram mortos no 7º dia com a mesma denominação do 7º dia. Em cada animal foi realizado gastrotomia e gastrorrafia em plano único com fio polipropileno 6-0 (Prolene®, Ethicon. Os animais do grupo Jatropha receberam dose única de 200mg/Kg do extrato bruto de Jatropha gossypiifolia L via intraperitoneal no dia do procedimento e os do grupo controle a mesma quantidade em mililitros de solução salina (cloreto de sódio à 0,9%. Foram avaliados os seguintes parâmetros: 1 alterações macroscópicas; 2 a resistência à insuflação de ar atmosférico (pressão de ruptura da sutura; 3 características histológicas. RESULTADOS: Não houve morte dos animais na evolução clínica, ocorrendo boa cicatrização da parede abdominal, com ausência de sinais de infecção, deiscência, abscessos ou peritonites. A cicatrização da superfície serosa foi considerada boa em todos os animais, não ocorrendo fístulas, porém, as aderências intra-peritoneais ocorreram em sete ratos do subgrupo controle e nove do subgrupo Jatropha do 3º dia pós-operatório e em nove do subgrupo controle e oito do subgrupo Jatropha do 7º dia, não havendo diferenças estatisticamente significantes entre os grupos. A cicatrização da superfície mucosa foi classificada como boa em todos os animais. A resistência das gastrorrafias à insuflação de ar atmosférico demonstrou aumento estatisticamente significante da pressão de ruptura no grupo Jatropha do 3º dia de observação. A avaliação histológica demonstrou diferenças estatisticamente significantes, quanto aos critérios, reação inflamatória aguda menor e coaptação das bordas maior no subgrupo Jatropha do 7º dia pós-operatório em relação ao grupo controle do mesmo período. CONCLUSÃO: O extrato bruto de Jatropha gossypiifolia L. favorece a cicatrização no 3º dia pós-operatório em relação à maior resistência das gastrorrafias à pressão de ruptura, e no 7º dia com melhor coaptação das bordas e reduzindo reação inflamatória aguda à microscopia.INTRODUCTION: The healing process of the gastrointestinal tract is of huge importance in the surgical field history, as well as the search for appropriate types of threads and suture techniques and the many factors that influence it. The use of phytotherapic drugs as accelerators of the healing process has been done for many years and is one of the current objectives of scientific researches trying to prove its therapeutic properties. PURPOSE: To evaluate the use of Jatropha gossypiifolia L. extract on the healing process of gastrorraphies in rats. METHODS: Forty wistar male rats were divided in 2 groups of 20 rats, named control and Jatropha groups. Ten animals of each group were killed in the third day post-surgery and were named control and Jatropha groups of the 3rd day. The remaining 10 animals of each group were killed in the seventh day and were named accordingly for the 7th day. In each animal, gastrostomy and gastrorraphy were performed in a single plane using polypropylene thread 6-0 (Prolene. The animals from the Jatropha group were given a single dose of 200 mg/kg of the Jatropha gossypiifolia L. extract intraperitoneally on the same day of the procedure and the ones from the control group were given the same quantity in milliliters (ml, but of saline solution (sodium chloride 0.9%. The following parameters were evaluated: 1 macroscopic alterations; 2 the suture's resistance to atmospheric air insufflation (pressure of rupture; 3 histologic characteristics. RESULTS: No animal died during the clinical follow-up and optimal healing of the abdominal wall was seen without any signs of infection, dehiscence, abscesses or peritonitis. Healing of the serous surface was considered good in all animals, without occurrence of fistulas; however, intraperitoneal adhesions occurred in 7 rats of the sub-group control and 9 of the sub-group Jatropha on the 3rd day post-operative and in 9 of the sub-group control and 8 of the sub-group Jatropha on the 7th day, but the differences were not statistically significant between the groups. Healing of the mucous surface was classified as good in all the animals. The resistance of the gastrorraphies to the atmospheric air insufflation showed statistically significant increase of the rupture pressure in the Jatropha group during the 3rd day of observation. Histologic evaluation showed differences that were statistically significant, considered the criteria, as well as reduced acute inflammatory reaction and better coaptation of the edges in the sub-group Jatropha of 7th post-surgery, when comparet to the sub-group control of the same period. CONCLUSION: The raw extract of Jatropha gossypiifolia L. aids the healing on the 3rd day post-surgery, concerning the enhanced resistance of the gastrorraphies to pressure of rupture, and on the 7th day, presenting better coaptation of the edges and reducing acute inflammatory reaction by microscopic analyses.

    Full Text Available This study evaluated the effect of light, temperature, physiologic stage at harvest and length of time on the germination of Hyptis marrubioides seeds. Two trials were conducted. The first experiment was performed immediately after the seed harvest and consisted of a 2 x 3 x 3 factorial design with 2 environmental conditions (light and dark, 3 temperatures (20, 30 and 20/30ºC and 3 seed harvest times (green colored seeds, light brown seeds and dark brown seeds. 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.

  20. Post-9/11 Discourses Of Threat And Constructions Of Terror In The Age Of Obama

    Directory of Open Access Journals (Sweden)

    Mary K. Bloodsworth-Lugo

    2011-09-01

    In the present paper, we argue that the post-9/11 language of “us versus them” (“Either you are with us, or you are with the terrorists” [Bush 2001], delivered to the American public and international community to garner consent in the wake of the September 11, 2001 events, and transformed into public policy for the remainder of the G.W. Bush presidency, provided a lens through which Americans would continue to construct and perceive the world beyond the Bush administration.  Ideology surrounding “the War on Terror,” in particular, has either been resisted or co-opted and deployed by social agents in the aftermath of September 11, 2001.  We claim that in the age of Obama, Bush-generated discourse and ideology has been activated to continue and advance policies and practices aimed at identifying and containing “terrorist” threats.
