  1. CAL3JHH: a Java program to calculate the vicinal coupling constants (3 J H,H) of organic molecules

    Science.gov (United States)

    Aguirre-Valderrama, Alonso; Dobado, José A.

    2008-12-01

    Here, we present a free web-accessible application, developed in the JAVA programming language for the calculation of vicinal coupling constant (3 J H,H) of organic molecules with the H-Csp3-Csp3-H fragment. This JAVA applet is oriented to assist chemists in structural and conformational analyses, allowing the user to calculate the averaged 3 J H,H values among conformers, according to its Boltzmann populations. Thus, the CAL3JHH program uses the Haasnoot-Leeuw-Altona equation, and, by reading the molecule geometry from a protein data bank (PDB) file format or from multiple pdb files, automatically detects all the coupled hydrogens, evaluating the data needed for this equation. Moreover, a "Graphical viewer" menu allows the display of the results on the 3D molecule structure, as well as the plotting of the Newman projection for the couplings.

  3. Impact of Performance Management in Public and Private Organizations

    DEFF Research Database (Denmark)

    Hvidman, Ulrik; Andersen, Simon Calmar

    2014-01-01

    Recent theoretical developments suggest that management actions have different impacts on outcomes in public and private organizations. This proposition is important to public organizations’ widespread import of private sector management tools such as performance management. This article examines...... how performance management influences performance outcomes in otherwise similar public and private organizations. Showing that the factors expected to diminish the impact of performance management parallel the organizational characteristics of public organizations, we hypothesize that this type...... of management is less effective in public organizations. A difference-in-differences model based on survey data on management in Danish public and private schools, combined with administrative data of students’ test scores, confirms the hypothesis. The results have important implications for the transfer...

    2016-01-01

    Full Text Available Human resource management (HRM is a management concept which obtains many practices and activities. Although there is a substantial literature on HRM in the private sector, the practice of HRM in the public sector is still scarce. In the private sector, HRM is found as a factor for gaining competitive advantage, especially if HR practices are implemented in the way of high-performing working practice (HPWP. In the public sector, HRM is seen as paternalistic management, with the standardization of employment practices, collective bargaining and working practices that emphasize equal opportunities for employees. The goal of this research is to explore the characteristics and differences between HRM practice in organizations from the private and public sector. The subject of the research is HRM practice (staffing, training and development, compensation and benefits, and industrial relation and communication in the private and public organizations in the Republic of Serbia. The methodology of the paper includes exploration of the available literature on the theme and statistical analysis of the differences between HR practices in organizations from the private and public sector. The research is based on the HR data gathered in the second CRANET research round in Serbia, performed in 2015.

    Full Text Available Today, private forest owners (PFOs in Serbia cooperate in form of private forest owners associations (PFOAs. Currently, there are 20 PFOAs, of which 15 are in Timok region. Initiatives of PFOs from Timok forest area, animated the owners from other parts of the country and led to foundation of Serbian Federation of Forest Owners' Associations. Twelve of PFOAs from Timok forest area are the founders of Serbian private forest owners' umbrella organization. Restructuring of Public Enterprise (PE "Srbijasume", which started in 2001, led to development of private small and medium forest enterprises, engaged as contractors of PE for harvesting, timber transport and construction of forest roads. The objectives of this paper are to elaborate if there are differences between PFOs in Serbia and Timok region and to analyze organization of private forest owners in Timok forest area. In order to reach these objectives, results of PRIFORT project were used. This project focused on four countries of Western Balkans region: Bosnia and Herzegovina, Croatia, Serbia and Macedonia. The aim of this project was to explore precondition for formation of PFOs in this region. Quantitative survey (n = 350 of randomly selected PFOs was conducted in nine municipalities in Serbia, of which two were in Timok region (n = 100. The results show that there are differences between PFOs in Serbia and Timok region in number of PFOs, size of private property and in additional incentives. These results also indicate that economic interest is a motive for establishment of PFOAs and that state support is very important for their development. Since a number of PFOs are entrepreneurs, it can be assumed that, further development of theirs organizations could lead to development of SMEs clusters.

  11. The Balanced Scorecard in Portuguese Private Organizations: A Descriptive Analysis

    Directory of Open Access Journals (Sweden)

    Patrícia Rodrigues Quesado

    2012-06-01

    Full Text Available The understanding that the existing models applied to business performance evaluation were obsolete and could induce companies to taking erroneous decisions led to the development of information and management control systems that reflect the evolution of the non-financial or qualitative key success factors, such as the Balanced Scorecard (BSC. Nowadays, the BSC is one of the most popular management accounting tools. However, reports of high rates of failure require a more close analysis at the challenges and key issues with which various private organizations were confronted in its implementation. Consequently, even after more than two decades after the creation of the model, and despite the introduction of some improvements, investment in BSC projects within the corporate and academic environments can still be confirmed. Thus, in order to find out if Portuguese organizations know and implement the BSC, we sent a questionnaire to 549 private organizations, obtaining a response rate of 28.2%. The results suggest that although the majority of respondents know the BSC, its implementation in these organizations is limited and very recent.

By asking this question, we are thinking of a person responsible with organizing or coordinatingwork or the ones hired to do this, to think of what people want, to solve the management problems in group.This study is intended as a comparison of the two types of leadership (transformational vs. transactional interms of employee performance in public and private organizations. To measure performance and chose twoindicators: satisfaction and productivity. This study falls into the category of research studies the type ofdriving through subordinates with both theoretical and practical implications. The efficiency of this type ofleadership has been demonstrated by studies especially in the political and military and very few studies havebeen made in industrial .Type of transformational leadership is better than transactional perceived astransformational leaders are closer to the needs of employees and continuously investigate these necessities.This paper presents a practical validity as advising managers to develop a transformational type of leadership,both public and private organizations, leads to better performance. Also open new avenues of research,among which we can mention: study the impact of organizational culture on the adoption of transformationaltype vs transactional type; decision-making mechanisms in the type of transformational leadership; initiatetraining programs to develop a transformational type of leadership.

  3. Mapping private-public-partnership in health organizations: India experience

    Directory of Open Access Journals (Sweden)

    Nayan Chakravarty

    2015-04-01

    Full Text Available The dream of universal health care demands a much larger and wider approach, engaging not just the public but also the private sector. This paper has attempted mapping the present public-private partnership scenario in India using the WHO health system functions framework, giving an insight into the nature and extent of challenge of the present dominant model. A systematic review methodology was adopted to identify published literature on private-public partnership in India. From an initial pool of 785 articles were identified. Finally a total of 29 published articles meeting the inclusion criteria were included. The descriptive framework of Health system functions by WHO (2000, were used to analyze the data. All papers which were considered for the study were segregated based on the 4 prime health system functions: Financing; Management of non-financial inputs; Health service delivery and Oversight. The literature review reveals that more than half of the papers (51.72% selected for the study were focused on health service delivery functions and quite thin literature were available for other 3 functions, which includes financing, management of non-financial inputs and oversight functions as per WHO. This finding raise an important question if the genesis of most of the public-private partnerships is out of the inability of the public sector in reaching out to a particular target group by virtue of its geographical position or difficulty in working with high risk groups. Considering the limitations of the present model of engagement of private and public sectors, it demands for an alternative model of engagement where the mutual strength that exists with each one of the partners, could be harnessed and complemented. An alternate model is to engage in tri-partite partnership (TPP between the government, non-government and the corporates.

    Full Text Available In this paper we contrast different aspects of non-profit organizations’ performance from the perspective of their funding sources. Based on previous empirical results indicating that sources of funding influence fundraising performance, we extend the existing research to the analysis of overall non-profit organizational performance. We use the social constructivist approach to non-profit performance to discuss contrasts between privately and publicly funded humanitarian organizations in Croatia. Some differences in growth- and development-oriented measures of nonprofit performance for these groups are identified and discussed in the context of future regional research.

  7. Numerical Simulations of HH 555

    CERN Document Server

    Kajdic, Primoz

    2007-01-01

    We present 3D gasdynamic simulations of the Herbig Haro object HH 555. HH 555 is a bipolar jet emerging from the tip of an elephant trunk entering the Pelican Nebula from the adjacent molecular cloud. Both beams of HH 555 are curved away from the center of the H II region. This indicates that they are being deflected by a side-wind probably coming from a star located inside the nebula or by the expansion of the nebula itself. HH 555 is most likely an irradiated jet emerging from a highly embedded protostar, which has not yet been detected. In our simulations we vary the incident photon flux, which in one of our models is equal to the flux coming from a star 1 pc away emitting 5x10^48 ionizing (i. e., with energies above the H Lyman limit) photons per second. An external, plane-parallel flow (a ``side-wind'') is coming from the same direction as the photoionizing flux. We have made four simulations, decreasing the photon flux by a factor of 10 in each simulation. We discuss the properties of the flow and we co...

    1994-01-01

    HH 80-81 are two optically visible Herbig-Haro (HH) objects located about 5 minutes south of their exciting source IRAS 18162-2048. Displaced symmetrically to the north of this luminous IRAS source, a possible HH counterpart was recently detected as a radio continuum source with the very large array (VLA). This radio source, HH 80 North, has been proposed to be a member of the Herbig-Haro class since its centimeter flux density, angular size, spectral index, and morphology are all similar to those of HH 80. However, no object has been detected at optical wavelengths at the position of HH 80 North, possibly because of high extinction, and the confirmation of the radio continuum source as an HH object has not been possible. In the prototypical Herbig-Haro objects HH 1 and 2, ammonia emission has been detected downstream of the flow in both objects. This detection has been intepreted as a result of an enhancement in the ammonia emission produced by the radiation field of the shock associated with the HH object. In this Letter we report the detection of the (1,1) and (2,2) inversion transitions of ammonia downstream HH 80 North. This detection gives strong suppport to the interpretation of HH 80 North as a heavily obscured HH object. In addition, we suggest that ammonia emission may be a tracer of embedded Herbig-Haro objects in other regions of star formation. A 60 micrometer IRAS source could be associated with HH 80 North and with the ammonia condensation. A tentative explanation for the far-infrared emission as arising in dust heated by their optical and UV radiation of the HH object is presented.

    Full Text Available The article deals with various aspects of the private labels building. It primarily focuses on organic food market in the Czech Republic, but on this market it illustrates the general trends, both in brand building, as well as in the importance of a brand in purchasing decisions. Organic food market is specific as there is high importance of product attributes, which are based on customer's confidence. Many of the important criteria for the decision to purchase (the way of cultivation and processing of food, freshness, taste, etc. are not possible to be objectively assessed before buying. A brand name plays a large role in the confidence based attributes. Consumers perceive it as a certain guarantee of the expected quality. In the field of organic food there are still not strong brands but there is the space and the need to differentiate organic from conventional foods, in particular. A suitable option could be the retail chain private labels, which are already partially developed as far as for consumers subconscious expectations are concerned. The final part of the article provides an overview of the current offer of organic food private labels in the Czech Republic.

    Full Text Available The job satisfaction of employees has been a focal point of private organizations and also a source of attention for researchers in recent times. May be, this is because of relations between organizational outcomes and job satisfaction matters. This study informs about relationships between biographical variables and job satisfaction of private organizations because job satisfaction of private organizations employees may be concerned with the personal attributes such as age, gender and years of experience. Objective of the study is the improvement of organizational Human Resource Management system regarding worker’s job satisfaction, so Correlation, Regression and Analysis of Variance tests were conducted to test the data. Some of management variables, which were, Compensation, Empowerment, Work Place, Appraisal System, Management Behavior, Motivation, Clear Goals of Organization and Training and Development shown a positively correlation with employee’s job satisfaction. Implications for these factors and their connection with job satisfaction is argued, limitations of the study and future research recommendations are presented. Data was collected through a questionnaire. To test the research hypothesis, Correlation was conducted. Biographical differences specially gender, age and experience were related to many job satisfaction variables. We explore the effects of organizational aspects on employee’s satisfaction which leads to productivity.

  15. A Jet Model of HH Objects

    Science.gov (United States)

    Tenorio-Tagle, Guillermo; Rozyczka, Michal; Cantó, Jorge

    It is shown by means of two dimensional hydrodynamical simulations that Canto's model of HH objects does not lead to an entirely stationary flow. It causes both a stationary cylindrical shock (at the interaction place) and a fast moving region emitting an HH spectra. A coherent picture of these phenomena is here presented. The models account for "optical jet" structures embedded in a much larger (>0.1 pc) hydrodynamical jet at the tip of which an HH object should be found.

  16. A Hh-driven gene network controls specification, pattern and size of the Drosophila simple eyes.

    During development, extracellular signaling molecules interact with intracellular gene networks to control the specification, pattern and size of organs. One such signaling molecule is Hedgehog (Hh). Hh is known to act as a morphogen, instructing different fates depending on the distance to its source. However, how Hh, when signaling across a cell field, impacts organ-specific transcriptional networks is still poorly understood. Here, we investigate this issue during the development of the Drosophila ocellar complex. The development of this sensory structure, which is composed of three simple eyes (or ocelli) located at the vertices of a triangular patch of cuticle on the dorsal head, depends on Hh signaling and on the definition of three domains: two areas of eya and so expression--the prospective anterior and posterior ocelli--and the intervening interocellar domain. Our results highlight the role of the homeodomain transcription factor engrailed (en) both as a target and as a transcriptional repressor of hh signaling in the prospective interocellar region. Furthermore, we identify a requirement for the Notch pathway in the establishment of en maintenance in a Hh-independent manner. Therefore, hh signals transiently during the specification of the interocellar domain, with en being required here for hh signaling attenuation. Computational analysis further suggests that this network design confers robustness to signaling noise and constrains phenotypic variation. In summary, using genetics and modeling we have expanded the ocellar gene network to explain how the interaction between the Hh gradient and this gene network results in the generation of stable mutually exclusive gene expression domains. In addition, we discuss some general implications our model may have in some Hh-driven gene networks.

    The U.S. Geological Survey (USGS) collected or compiled data on volatile organic compounds (VOCs) in samples of untreated ground water from 1,926 rural private wells during 1986 to 1999. At least one VOC was detected in 12 percent of samples from rural private wells. Individual VOCs were not commonly detected with the seven most frequently detected compounds found in only 1 to 5 percent of samples at or above a concentration of 0.2 microgram per liter (??g/l). An assessment level of 0.2 ??g/l was selected so that comparisons of detection frequencies between VOCs could be made. The seven most frequently detected VOCs were: trichloromethane, methyl tert-butyl ether, tetrachloroethene, dichlorodifluoromethane, methylbenzene, 1,1,1-trichloroethane, and 1,2-dibromo-3-chloropropane. Solvents and trihalomethanes were the most frequently detected VOC groups in private wells. The distributions of detections of gasoline oxygenates and fumigants seemed to be related to the use patterns of compounds in these groups. Mixtures were a common mode of occurrence of VOCs with one-quarter of all samples with detections including two or more VOCs. The concentrations of most detected VOCs were relatively small and only 1.4 percent of samples had one or more VOC concentrations that exceeded a federally established drinking water standard or health criterion.

    While the European Union has put a lot of emphasis on cluster development due to their inherent advantages such as lower transaction costs, technological transfer and regional development, little is known about how clusters emerge and what can facilitate their competitiveness. This paper aims to study the impact of public-private cooperation between universities and organizations on cluster development and competitiveness. A literature review is employed to develop the model while 4 qualitative case studies provide the initial test of its validity. The analysis suggests that cooperating with research institutions impacts cluster development first through education of industrial staff, but also by developing innovation processes through the facilitation of the appearance of innovative ideas and also of knowledge sharing among organizations. The research has several implications both for organizations and for government officials. First of all, R&D and top management should actively seek to cooperate with research institutions both for training of their staff but also in seeking new ideas and as a way of collaborating with other organizations within the field without fear of losing competitive advantage. Second, government officials should try to create more incentives both for organizations (through for example tax returns) and for universities (extra funding or salary incentives) that can increase collaboration between these actors. This paper is the first one to asses empirically how cooperation with research institutions affect cluster competitiveness and development, especially within the developing region of Eastern Europe, Romania.

    Full Text Available This study aimed to identify the use of management tools and the influence of stakeholders on organizational performance of companies in the private health sector in the Federal District. We used the tools of strategic management, such as budgeting, strategic planning, balanced scorecard, benchmarking, and management software. Study participants consist of individuals involved in strategic processes. We analyzed the past 5 years in organizations to understand the performance. The data collection was face-to-face, the instruments consisted of qualitative interviews in person, and semi-structured content analysis. We also performed analysis of secondary data and documents. To measure the performance between the organizations we used the method of data envelopment analysis (DEA, using the CCR standard, and the mean change index as the number of employees, physicians, costs, number of appointments, and tests. In the analysis of tools and stakeholders we adapted values for the major and minor influences and the other results found framed. The results cite the presence of management tools in five of the six organizations. The comparison of performance between them presented as a result that organizations 2 and 4 were efficient and 3 was the least efficient. The study identified the need to understand the requirements of stakeholders and the indicators set out to understand organizational performance and its evolution, mainly determined by the management tools. Although not reaching proposed levels, this work creates hypotheses about the use of these tools and analysis of stakeholders in organizational performance.

    We consider newly derived proper motions of the HH 34 jet to reconstruct the evolution of this outflow. We first extrapolate ballistic trajectories for the knots (starting from their present-day positions and velocities) and find that at {approx}1000 yr in the future most of them will merge to form a larger-mass structure. This mass structure will be formed close to the present-day position of the HH 34S bow shock. We then carry out a fit to the ejection velocity versus time reconstructed from the observed proper motions (assuming that the past motion of the knots was ballistic) and use this fit to compute axisymmetric jet simulations. We find that the intensity maps predicted from these simulations do indeed match reasonably well the [S II] structure of HH 34 observed in Hubble Space Telescope images.

    We discuss the choice of target values for the peak and integrated luminosity of a future high-energy frontier circular hadron collider (FCC-hh). We review the arguments on the physics reach of a hadron collider. Next we show that accelerator constraints will limit the beam current and the turnaround time. Taking these limits into account, we derive an expression for the ultimate integrated luminosity per year, depending on a possible pile-up limit imposed by the physics experiments. We finally benchmark our result against the planned two phases of FCC-hh [1, 2, 3

    2004-01-01

    We report detections of X-rays from HH 80 and HH 81 with the ACIS instrument on the Chandra X-ray Observatory. These are among the most luminous HH sources in the optical and they are now the most luminous known in X-rays. These X-rays arise from the strong shocks that occur when the southern extension of this bipolar outflow slams into the ambient material. There is a one-to-one correspondence between regions of high X-ray emission and high H? emission. The X-ray luminosities of HH 80 and HH 81 are 4.5 and 4.3 x 1031 erg s-1, respectively, assuming the measured low-energy absorption is not in the sources. The measured temperature of the HH plasma is not as large as that expected from the maximum velocities seen in the extended tails of the optical emission lines. Rather it is consistent with the ~106 K temperature of the ?narrow? core of the optical lines. There is no observed emission from HH 80 North, the northern extension of the bipolar flow, based upon a measurement of lower sensitivity. We imaged the c...

Eight fields of 5\\prime\\prime × 3\\buildrel{\\prime\\prime}\\over{.} 5 have been positioned along and across the HH 111 jet, covering the spatial region from knot E to L in HH 111 (namely, knots E, F, G, H, J, K, and L). We present images and velocity channel maps for the [O i] 6300+6360, Hα, [N ii] 6548+6583, and [S ii] 6716+6730 lines, as well as for the [S ii] 6716/6730 line ratio. We find that the HH 111 jet has an inner region with lower excitation and higher radial velocity, surrounded by a broader region of higher excitation and lower radial velocity. Also, we find higher electron densities at lower radial velocities. These results imply that the HH 111 jet has a fast, axial region with lower velocity shocks surrounded by a lower velocity sheath with higher velocity shocks.

  10. Perceptions of Nongovernmental Organization (NGO Staff about Water Privatization in Developing Countries

    Directory of Open Access Journals (Sweden)

    Ellis A. Adams

    2014-11-01

    Full Text Available Almost a billion people globally lack access to potable water. In the early 1990’s, attempts to improve potable water access in the global south included a massive push for water services privatization, often involving the transfer of public water services to private companies. Critics of water privatization claim it rarely improves access to water, and in most cases, unfairly affect poor people. Proponents on the other hand argue that it is necessary for efficient management and capital investment in the water sector. Although development NGOs play an important role in developing country water provision, hardly any studies have sought to understand their perceptions about the potential role of water privatization towards improving access to potable water in developing countries. We interviewed the key staff among 28 international and national NGO staff about water privatization, its opportunities and constraints. Their perceptions were mixed. While most criticized water privatization as increasing water costs to the poor, some noted that privatization is necessary for improving water access through increased capital investment. We present the findings and discuss larger implications for water policies and reforms in developing countries.

  12. Ihog and Boi elicit Hh signaling via Ptc but do not aid Ptc in sequestering the Hh ligand.

    Hedgehog (Hh) proteins are secreted molecules essential for tissue development in vertebrates and invertebrates. Hh reception via the 12-pass transmembrane protein Patched (Ptc) elicits intracellular signaling through Smoothened (Smo). Hh binding to Ptc is also proposed to sequester the ligand, limiting its spatial range of activity. In Drosophila, Interference hedgehog (Ihog) and Brother of ihog (Boi) are two conserved and redundant transmembrane proteins that are essential for Hh pathway activation. How Ihog and Boi activate signaling in response to Hh remains unknown; each can bind both Hh and Ptc and so it has been proposed that they are essential for both Hh reception and sequestration. Using genetic epistasis we established here that Ihog and Boi, and their orthologs in mice, act upstream or at the level of Ptc to allow Hh signal transduction. In the Drosophila developing wing model we found that it is through Hh pathway activation that Ihog and Boi maintain the boundary between the anterior and posterior compartments. We dissociated the contributions of Ptc from those of Ihog/Boi and, surprisingly, found that cells expressing Ptc can retain and sequester the Hh ligand without Ihog and Boi, but that Ihog and Boi cannot do so without Ptc. Together, these results reinforce the central role for Ptc in Hh binding in vivo and demonstrate that, although Ihog and Boi are dispensable for Hh sequestration, they are essential for pathway activation because they allow Hh to inhibit Ptc and thereby relieve its repression of Smo.

    We present VLT-ISAAC medium resolution spectroscopy of the HH34 and HH1 jets. Our aim is to derive the kinematics and the physical parameters and to study how they vary with jet velocity. We use several important diagnostic lines such as [FeII] 1.644um, 1.600um and H2 2.122um. In the inner jet region of HH34 we find that both the atomic and molecular gas present two components at high and low velocity. The [FeII] LVC in HH34 is detected up to large distances from the source (>1000 AU), at variance with TTauri jets. In H2 2.122um, the LVC and HVC are spatially separated. We detect, for the first time, the fainter red-shifted counterpart down to the central source. In HH1, we trace the jet down to ~1" from the VLA1 driving source: the kinematics of this inner region is again characterised by the presence of two velocity components, one blue-shifted and one red-shifted with respect to the source LSR velocity. In the inner HH34 jet region, ne increases with decreasing velocity. Up to ~10" from the driving source,...

    Antoniucci, S; Giannini, T; Lorenzetti, D

    2007-01-01

    We present the results of a near-IR spectroscopic analysis on 3 young embedded sources (HH26IRS, HH34IRS and HH46IRS) belonging to different star-forming regions and displaying well developed jet structures. The aim is to investigate the source accretion and ejection properties and their connection. We used VLT-ISAAC spectra (R~9000, H and K bands) to derive in a self-consistent way parameters like the star luminosity, the accretion luminosity and the mass accretion rate. Mass loss rates have also been estimated from the analysis of different emission features. The spectra present several emission lines but no photospheric features in absorption, indicating a large veiling in H and K. We detected features commonly observed in jet-driving sources (HI,[FeII],H_2,CO) and also a number of emission lines due to permitted atomic transitions, like NaI and TiI. The NaI 2.2um doublet is observed along with CO(2-0) band-head emission, indicating a common origin in an inner gaseous disc heated by accretion. We find that...

    We describe a new method for determining proper motions of extended objects, and a pipeline developed for the application of this method. We then apply this method to an analysis of four epochs of [S II] HST images of the HH 1 jet (covering a period of ≈20 yr). We determine the proper motions of the knots along the jet, and make a reconstruction of the past ejection velocity time-variability (assuming ballistic knot motions). This reconstruction shows an "acceleration" of the ejection velocities of the jet knots, with higher velocities at more recent times. This acceleration will result in an eventual merging of the knots in ≈450 yr and at a distance of ≈80'' from the outflow source, close to the present-day position of HH 1.

    The HH Seismic hammer is a large, "weight-drop" source for active source seismic experiments. This system provides a repetitive source that can be stacked for subsurface imaging and exploration studies. Although the seismic hammer was designed for seismological studies it was surmised that it might produce energy in the infrasonic frequency range due to the ground motion generated by the 13 metric ton drop mass. This study demonstrates that the seismic hammer generates a consistent acoustic source that could be used for in-situ sensor characterization, array evaluation and surface-air coupling studies for source characterization.

    We present numerical hydrodynamical simulations of a time-dependent ejection velocity precessing jet. The parameters used in our models correspond to a high excitation Herbig-Haro object, such as HH 80/81. We have included the transfer of ionizing radiation produced within the shocked regions of the jet. The radiative transfer is computed with a ray-tracing scheme from all the cells with an emissivity above a certain threshold. We show the development of a radiative precursor, and compare the morphology with a model without the diffuse radiation. Our simulations show that the morphology of the Hα emission is affected considerably if the diffuse ionizing radiation is accounted for. The predicted Hα position-velocity diagram (i.e., spatially resolved emission line profiles) from a model with the transfer of ionizing radiation has a relatively strong component at zero velocity, corresponding to the radiative precursor. Qualitatively similar 'zero velocity components' are observed in HH 80/81 and in the jet from Sanduleak's star in the Large Magellanic Cloud.

    Huntoon, R. B.

    1984-01-01

    Communication, navigation, flight control, and search sensor management are avionics functions which constitute every Search and Rescue (SAR) operation. Routine cockpit duties monopolize crew attention during SAR operations and thus impair crew effectiveness. The United States Coast Guard challenged industry to build an avionics system that automates routine tasks and frees the crew to focus on the mission tasks. The HH-64A SAR avionics systems of communication, navigation, search sensors, and flight control have existed independently. On the SRR helicopter, the flight management system (FMS) was introduced. H coordinates or integrates these functions. The pilot interacts with the FMS rather than the individual subsystems, using simple, straightforward procedures to address distinct mission tasks and the flight management system, in turn, orchestrates integrated system response.

    2008-01-01

    HH 262 is a group of emitting knots displaying an "hour-glass" morphology in the Halpha and [SII] lines, located 3.5' to the northeast of the young stellar object L1551-IRS5, in Taurus. We present new results of the kinematics and physical conditions of HH 262 based on Integral Field Spectroscopy covering a field of 1.5'x3', which includes all the bright knots in HH 262. These data show complex kinematics and significant variations in physical conditions over the mapped region of HH 262 on a spatial scale of <3". A new result derived from the IFS data is the weakness of the [NII] emission (below detection limit in most of the mapped region of HH 262), including the brightest central knots. Our data reinforce the association of HH 262 with the redshifted lobe of the evolved molecular outflow L1551-IRS5. The interaction of this outflow with a younger one, powered by L1551 NE, around the position of HH 262 could give rise to the complex morphology and kinematics of HH 262.

    Veterinarians could be the expected sparring partners of organic dairy farmers in promoting animal health which is one of the main organic principles. However, in the past organic dairy farmers did not always consider veterinarians to be pertinent advisors for them. The objectives of this study are - from private veterinary practitioners' point of views- i) to describe the roles of veterinarians today in organic dairy farmers' animal health promotion strategies, ii) to identify factors related to organic farming which determine their role on organic dairy farms, and, iii) to identify opportunities for improvement of veterinarians' advisory services for organic dairy herds. Fourteen veterinarians, providing herd health advisory services to dairy farmers, were interviewed using qualitative semi-structured research interviews. A modified approach to Grounded Theory was used for data collection and analysis. Most often veterinarians had only contact with the organic dairy farmers in cases of individual ill animals or acute herd health problems. Even though certain veterinarians experienced situations and approaches of animal health and welfare on organic dairy farms not meeting their standards, they were not always able to establish themselves an advisory role supporting farmers in improving this. Indeed, organic production principles, regulations and farmers' health approaches challenged veterinarians' values on animal health and welfare and their perceptions of 'good veterinary practices'. Also, some veterinarians considered that there was no direct economic interest for them in the organic dairy sector and that could diminish their willingness to invest in this sector. Possible opportunities for improvement were identified; for example proposing more proactively advice via existing organisations, by making adaptations to advisory services for the organic sector and/or by dissociating veterinarians' curative role from their advisory role in disease prevention.

  13. The Sinorhizobium fredii HH103 lipopolysaccharide is not only relevant at early soybean nodulation stages but also for symbiosome stability in mature nodules.

    Directory of Open Access Journals (Sweden)

    Isabel Margaret

    Full Text Available In this work we have characterised the Sinorhizobium fredii HH103 greA lpsB lpsCDE genetic region and analysed for the first time the symbiotic performance of Sinorhizobium fredii lps mutants on soybean. The organization of the S. fredii HH103 greA, lpsB, and lpsCDE genes was equal to that of Sinorhizobium meliloti 1021. S. fredii HH103 greA, lpsB, and lpsE mutant derivatives produced altered LPS profiles that were characteristic of the gene mutated. In addition, S. fredii HH103 greA mutants showed a reduction in bacterial mobility and an increase of auto-agglutination in liquid cultures. RT-PCR and qPCR experiments demonstrated that the HH103 greA gene has a positive effect on the transcription of lpsB. Soybean plants inoculated with HH103 greA, lpsB or lpsE mutants formed numerous ineffective pseudonodules and showed severe symptoms of nitrogen starvation. However, HH103 greA and lps mutants were also able to induce the formation of a reduced number of soybean nodules of normal external morphology, allowing the possibility of studying the importance of bacterial LPS in later stages of the S. fredii HH103-soybean symbiosis. The infected cells of these nodules showed signs of early termination of symbiosis and lytical clearance of bacteroids. These cells also had very thick walls and accumulation of phenolic-like compounds, pointing to induced defense reactions. Our results show the importance of bacterial LPS in later stages of the S. fredii HH103-soybean symbiosis and their role in preventing host cell defense reactions. S. fredii HH103 lpsB mutants also showed reduced nodulation with Vigna unguiculata, although the symbiotic impairment was less pronounced than in soybean.

  14. Crustacean hyperglycemic hormone (cHH as a modulator of aggression in crustacean decapods.

    Directory of Open Access Journals (Sweden)

    Laura Aquiloni

    Full Text Available Biogenic amines, particularly serotonin, are recognised to play an important role in controlling the aggression of invertebrates, whereas the effect of neurohormones is still underexplored. The crustacean Hyperglycemic Hormone (cHH is a multifunctional member of the eyestalk neuropeptide family. We expect that this neuropeptide influences aggression either directly, by controlling its expression, or indirectly, by mobilizing the energetic stores needed for the increased activity of an animal. Our study aims at testing such an influence and the possible reversion of hierarchies in the red swamp crayfish, Procambarus clarkii, as a model organism. Three types of pairs of similarly sized males were formed: (1 'control pairs' (CP, n = 8: both individuals were injected with a phosphate saline solution (PBS; (2 'reinforced pairs' (RP, n = 9: the alpha alone was injected with native cHH, and the beta with PBS; (3 'inverted pairs' (IP, n = 9: the opposite of (2. We found that, independently of the crayfish's prior social experience, cHH injections induced (i the expression of dominance behaviour, (ii higher glycemic levels, and (iii lower time spent motionless. In CP and RP, fight intensity decreased with the establishment of dominance. On the contrary, in IP, betas became increasingly likely to initiate and escalate fights and, consequently, increased their dominance till a temporary reversal of the hierarchy. Our results demonstrate, for the first time, that, similarly to serotonin, cHH enhances individual aggression, up to reverse, although transitorily, the hierarchical rank. New research perspectives are thus opened in our intriguing effort of understanding the role of cHH in the modulation of agonistic behaviour in crustaceans.

    Glassco, David H. J.; Glassco, Jordan C.

    2006-05-01

    Homeland security and defense applications seek to reduce the risk of undesirable eventualities across physical space in real-time. With that functional requirement in mind, our work focused on the development of IP based agent telecommunication solutions for heterogeneous sensor / robotic intelligent "Things" that could be deployed across the internet. This paper explains how multi-organization information and device sharing alliances may be formed to enable organizations to act as agents of homeland security (in addition to other uses). Topics include: (i) using location-aware, agent based, real-time information sharing systems to integrate business systems, mobile devices, sensor and actuator based devices and embedded devices used in physical infrastructure assets, equipment and other man-made "Things"; (ii) organization-centric real-time information sharing spaces using on-demand XML schema formatted networks; (iii) object-oriented XML serialization as a methodology for heterogeneous device glue code; (iv) how complex requirements for inter / intra organization information and device ownership and sharing, security and access control, mobility and remote communication service, tailored solution life cycle management, service QoS, service and geographic scalability and the projection of remote physical presence (through sensing and robotics) and remote informational presence (knowledge of what is going elsewhere) can be more easily supported through feature inheritance with a rapid agent system development methodology; (v) how remote object identification and tracking can be supported across large areas; (vi) how agent synergy may be leveraged with analytics to complement heterogeneous device networks.

    The HH588 flow is studied with multi-pupil spectrograph on the 2.6 m telescope of Byurakan observatory. The bright components of this flow are analyzed, using the maps of emission lines and radial velocities. The bipolar nature of this outflow is obvious from their radial velocities. The unusual feature of HH588 flow is its inclusion in the bright-rimmed cloud; thus, it can belong to so-called irradiated jets. It is worth to mention that all HH-objects studied here show a deceleration in the regions of interaction with the interstellar medium.

    Gültekin Altuntas

    2014-02-01

    Full Text Available Both competitive rivalry and internal communication play a crucial role for a business to position itself in a favourable manner in order to succeed particularly in a hostile environment. While numerous studies present the importance of competitive rivalry and of communication, even internal communication separately, little is known about the specific linkage of how competitive rivalry affects communication in the literature. Within the framework of internal communication, this study focuses on the notion that competitive rivalry is related to the path and style of communication as well as to the usage of internal communication tools but not to quality of communication. Thus, our research presents the linkage and the interaction between competitive rivalry and internal communication, of which the results indicate that, overall, competitive rivalry has a significant direct positive influence on internal communication dimensions in terms of path, style and quality of communication, as well as usage of communication tools in healthcare organizations.

    2008-12-01

    Full Text Available The uncertainty that accompanies organizational change heightens prospects for intra organizational conflict. Notwithstanding this, the knowledge base on the sources (or causes of organizational conflict is underdeveloped – largely as a result of a low incidence of empirical research, and in particular in South Africa. The current study explored the perceived sources of conflict in two South African organizations operating in different economic sectors. An experimental survey focusing on both the causes and the impact of conflict was administered to a sample of 203 employees, representing both companies. Comparative analysis revealed significant differences between the two organizations’ views with regard to the causes and consequences of conflict. The implications of these findings for future research and conflict management are discussed.

    2006-01-01

    We report the detection during the Chandra Orion Ultradeep Project (COUP) of two soft, constant, and faint X-ray sources associated with the Herbig-Haro object HH210. HH210 is located at the tip of the NNE finger of the emission line system bursting out of the BN-KL complex, northwest of the Trapezium cluster in the OMC-1 molecular cloud. Using a recent Halpha image obtained with the ACS imager on board HST, and taking into account the known proper motions of HH210 emission knots, we show that the position of the brightest X-ray source, COUP703, coincides with the emission knot 154-040a of HH210, which is the emission knot of HH210 having the highest tangential velocity (425 km/s). The second X-ray source, COUP704, is located on the complicated emission tail of HH210 close to an emission line filament and has no obvious optical/infrared counterpart. Spectral fitting indicates for both sources a plasma temperature of ~0.8 MK and absorption-corrected X-ray luminosities of about 1E30 erg/s (0.5-2.0 keV). These X...

    We imaged the Lynds 723 dark nebula (L723) with the aim of studying the morphology of the Herbig-Haro object HH 223 and other line-emission nebula detected in the region. We obtained deep narrow-band images in the Halpha and [SII] lines and in the continuum nearby Halpha of a field of ~5' of the L723 dark nebula centered on HH 223. The Halpha and [SII] images reveal the detailed morphology of HH 223, unresolved in previous optical images. Both images show a quite complex knotty, wiggling structure embedded in a low-emission nebula. Comparison between the [SII] and Halpha fluxes of the knots are indicative of variations in the excitation conditions through HH 223. In addition, several other faint nebula are detected in Halpha a few arcmin to the SE and to the NW of HH 223, all of them lying projected onto the east-west pair of lobes of the quadrupolar CO outflow. Comparison between the Halpha and the continuum images confirms the HH-like nature of the Vrba object V83, while the Vrba objects V84 and V85 are ide...

    The microstructure formation processes in HK40 and HH40 alloys were investigated through JmatPro calculations and quenching performed during directional solidification. The phase transition routes of HK40 and HH40 alloys were determined as L → L + γ → L + γ + M7C3 → γ + M7C3 → γ + M7C3 + M23C6→ γ + M23C6 and L → L + δ → L + δ + γ→ L + δ + γ + M23C6 δ + γ + M23C6, respectively. The solidification mode was determined to be the austenitic mode (A mode) in HK40 alloy and the ferritic-austenitic solidification mode (FA mode) in HH40 alloy. In HK40 alloy, eutectic carbides directly precipitate in a liquid and coarsen during cooling. The primary γ dendrites grow at the 60° angle to each other. On the other hand, in HH40 alloy, residual δ forms because of the incomplete transformation from δ to γ. Cr23C6 carbide is produced in solid delta ferrite δ but not directly in liquid HH40 alloy. Because of carbide formation in the solid phase and no rapid growth of the dendrite in a non-preferential direction, HH40 alloy is more resistant to cast defect formation than HK40 alloy.

    Contreiras, Henrique; Matta, Gustavo Corrêa

    2015-02-01

    The article describes and discusses privatization of the municipal health system in São Paulo, Brazil, from an administrative and political perspective. The methodology consisted of a literature review and analysis of legislation and public documents. The study showed that although legislation governing the so-called "Social Organizations" (OS) in Brazil dates to the year 2006, half of the administrative privatization is still regulated by a previous provisional instrument in the form of an "agreement" ("convênio" in Portuguese). In 2011, 61% of services were administered by private organizations, which received 44% of the health budget in 2012. The twenty participating organizations include five of the ten largest health care companies in Brazil. Inspection agencies have detected flaws in the management contracts, but the "agreements" (convênios) are subject to less rigorous control and have proven invisible to inspection. Finally, the legal framework is unstable. The study uses the experience in São Paulo as the basis for discussing the political versus technical nature of private management in the Brazilian Unified National Health System (SUS).

    Full Text Available In reality privatization has never occurred according to the handbook rules of ordinary market transactions. Not even in advanced market economies can privatization transactions be described by the Walrasian or Arrowian, or Leontiefian equilibrium models, or by the equilibrium models of the game theory. In these economies transactions of privatization take place in a fairly organic way – which means that those are driven by the dominance of private property rights and in a market economy. But despite this fact Western privatization also some peculiar features as compared to ordinary company takeovers, since the state as the seller may pursue non – economic goals. Changes in the dominant form of property change positions and status of many individuals and groups in the society. That’s why privatization can even less be explained by ordinary market mechanisms in transition countries where privatizing state-owned property have happened in a mass scale and where markets and private property rights weren't established at the time process of privatization began. In this paper I’ll discuss and analyze the phenomenon of privatization in context of different economic theories arguing that empirical results go in favor of the public choice theory (Buchanan, 1978, theory of "economic constitution" (Brennan and Buchanan 1985, (Buchanan and Tullock, 1989, and theory of "collective action" (Olson, 1982. These theories argues that transition from one economic system into another, for example transition from collectivistic, socialistic system into capitalism and free market economy with dominant private property, will not happen through isolated changes of only few economic institutions, no matter how deep that changes would be. In other words privatization can not give results if it's not followed by comprehensive change of economic system because privatized companied wouldn't be able to operate in old environment.

    Full Text Available The study was entirely designed by centering the focal problem of the effect of Glass Ceiling on Women Career Development. The overall study was structure based on the conceptual framework built up using the information of literature survey. The study was conducted with the aim of obtaining the following objective. That is “To find out the Effect of Glass Ceiling on Women Career Development with regard to female executive level employees who are working in privatesector organizations.” At the same time, hypotheses are developed to find out whether there is a significant effect of Individual Factors, Family Factors, Organizational Factors and Cultural Factors on Women Career development. Merely this study has been completed with an empirical survey which was thoroughly conducted using a self-administered questionnaire and the sample consisted of 150 women executives. For presenting and analyzing the data both descriptive andinferential statistics were used. The findings reveal that the Glass Ceiling and Women Career Development have a moderate negative relationship, and also show that Individual Factors, OrganizationalFactors and Cultural Factors have a significant effect on Women Career Development whereas Family Factor has effects on the Glass Ceiling. Following the study results, a conclusion was eventually made that there are significant effects of the Glass Ceiling on WomenCareer Development of Executive level female employees working in private sector organizations in Sri Lanka. By taking all these facts into consideration, better recommendations have been made in this study. Finally, the most valuable suggestions for further studies and limitations of the study have been outlined.

    2017-05-15

    Volatile Organic Compounds (VOCs) in indoor air were investigated at 39 private residences in Selangor State, Malaysia to characterize the indoor air quality and to identify pollution sources. Twenty-two VOCs including isomers (14 aldehydes, 5 aromatic hydrocarbons, acetone, trichloroethylene and tetrachloroethylene) were collected by 2 passive samplers for 24h and quantitated using high performance liquid chromatography and gas chromatography mass spectrometry. Source profiling based on benzene/toluene ratio as well as statistical analysis (cluster analysis, bivariate correlation analysis and principal component analysis) was performed to identify pollution sources of the detected VOCs. The VOCs concentrations were compared with regulatory limits of air quality guidelines in WHO/EU, the US, Canada and Japan to clarify the potential health risks to the residents. The 39 residences were classified into 2 groups and 2 ungrouped residences based on the dendrogram in the cluster analysis. Group 1 (n=30) had mainly toluene (6.87±2.19μg/m(3)), formaldehyde (16.0±10.1μg/m(3)), acetaldehyde (5.35±4.57μg/m(3)) and acetone (11.1±5.95μg/m(3)) at background levels. Group 2 (n=7) had significantly high values of formaldehyde (99.3±10.7μg/m(3)) and acetone (35.8±12.6μg/m(3)), and a tendency to have higher values of acetaldehyde (23.7±13.5μg/m(3)), butyraldehyde (3.35±0.41μg/m(3)) and isovaleraldehyde (2.30±0.39μg/m(3)). The 2 ungrouped residences showed particularly high concentrations of BTX (benzene, toluene and xylene: 235μg/m(3) in total) or acetone (133μg/m(3)). The geometric mean value of formaldehyde (19.2μg/m(3)) exceeded an 8-hour regulatory limit in Canada (9μg/m(3)), while those in other compounds did not exceed any regulatory limits, although a few residences exceeded at least one regulatory limit of benzene or acetaldehyde. Thus, the VOCs in the private residences were effectively characterized from the limited number of monitoring, and the

    Noriega-Crespo, A; Lora, V; Stapelfeldt, K R; Carey, S J

    2011-01-01

    We present Spitzer IRAC images of the HH 111 outflow, that show a wealth of condensations/knots in both jet and counterjet. Studying the positional distribution of these knots, we find very suggestive evidence of a mirror symmetric pattern in the jet/counterjet flow. We model this pattern as the result of an orbital motion of the jet source around a binary companion. From a fit of an analytic, ballistic model to the observed path of the HH 111 system, we find that the motion in a binary with two approx. 1 Msolar stars (one of them being the HH 111 source), in a circular orbit with a separation of approx. 186 AU would produce the mirror symmetric pattern seen in the outflow.

    The goal of this study is to extend research on evidence-based practice (EBP) implementation by examining the impact of organizational type (public versus private) and organizational support for EBP on provider attitudes toward EBP and EBP use. Both organization theory and theory of innovation uptake and individual adoption of EBP guide the approach and analyses in this study. We anticipated that private sector organizations would provide greater levels of organizational support for EBPs leading to more positive provider attitudes towards EBPs and EBP use. We also expected attitudes toward EBPs to mediate the association of organizational support and EBP use. Participants were mental health service providers from 17 communities in 16 states in the United States (n = 170). Path analyses were conducted to compare three theoretical models of the impact of organization type on organizational support for EBP and of organizational support on provider attitudes toward EBP and EBP use. Consistent with our predictions, private agencies provided greater support for EBP implementation, and staff working for private agencies reported more positive attitudes toward adopting EBPs. Organizational support for EBP partially mediated the association of organization type on provider attitudes toward EBP. Organizational support was significantly positively associated with attitudes toward EBP and EBP use in practice. This study offers further support for the importance of organizational context as an influence on organizational support for EBP and provider attitudes toward adopting EBP. The study demonstrates the role organizational support in provider use of EBP in practice. This study also suggests that organizational support for innovation is a malleable factor in supporting use of EBP. Greater attention should be paid to organizational influences that can facilitate the dissemination and implementation of EBPs in community settings.

Results Consistent with our predictions, private agencies provided greater support for EBP implementation, and staff working for private agencies reported more positive attitudes toward adopting EBPs. Organizational support for EBP partially mediated the association of organization type on provider attitudes toward EBP. Organizational support was significantly positively associated with attitudes toward EBP and EBP use in practice. Conclusion This study offers further support for the importance of organizational context as an influence on organizational support for EBP and provider attitudes toward adopting EBP. The study demonstrates the role organizational support in provider use of EBP in practice. This study also suggests that organizational support for innovation is a malleable factor in supporting use of EBP. Greater attention should be paid to organizational influences that can facilitate the dissemination and implementation of EBPs in

    In October, 1996 Private Moments, an adult novelty store, opened for business in Huntsville, Texas. Huntsville had no ordinances in place to prevent the opening of this type of business. In fact, the local Small Business Development Center provided guidance and assistance to Edward Delagarza, the founder and owner of Private Moments. Many of the Huntsville citizens, unhappy with the opening of Private Moments, approached the City Council requesting that it be closed immediately and asked for ...

    Full Text Available The author, based on the circumstances that contributed to the creation of private prisons, has explained the historical development of private prisons in the United States and Great Britain. After that, the author has analyzed the strengths and weaknesses of the prison run by private companies. Namely, the author has, stating the benefits of private prisons (reduced overcrowding penitencijarnih institution, cheaper accommodation cost per prisoner, provide better services, the possibility of applying a new philosophy in the manner of execution of sentence, with modern Penitentiary program, with the aim of re-socialization and the reduction of recidivism and weaknesses of the private prisons (the question of legitimac, a chronic lack of space in the Penitentiary system is not solved, business-oriented policies of private prisons, less salaries, poor performance of the security service, worst food, weak enforcement of parole, lack of appropriate penitentiary program, wanted to draw attention to the professional public about controversy of the introduction private companies in the management structure of penitentiary institutions . As the Republic of Serbia is, constantly in the last twenty years, faced with the increasing number of inmates, as well as the chronic shortage of money, which affects on the situation in industrial areas of prisons, there are options to give licenses to private companies to manage prisons. Therefore, the author has paid special attention to potential problems of introducing private prisons in the penitentiary system in Serbia.

  20. Structure and Biological Roles of Sinorhizobium fredii HH103 Exopolysaccharide

    Here we report that the structure of the Sinorhizobium fredii HH103 exopolysaccharide (EPS) is composed of glucose, galactose, glucuronic acid, pyruvic acid, in the ratios 5∶2∶2∶1 and is partially acetylated. A S. fredii HH103 exoA mutant (SVQ530), unable to produce EPS, not only forms nitrogen fixing nodules with soybean but also shows increased competitive capacity for nodule occupancy. Mutant SVQ530 is, however, less competitive to nodulate Vigna unguiculata. Biofilm formation was reduced in mutant SVQ530 but increased in an EPS overproducing mutant. Mutant SVQ530 was impaired in surface motility and showed higher osmosensitivity compared to its wild type strain in media containing 50 mM NaCl or 5% (w/v) sucrose. Neither S. fredii HH103 nor 41 other S. fredii strains were recognized by soybean lectin (SBL). S. fredii HH103 mutants affected in exopolysaccharides (EPS), lipopolysaccharides (LPS), cyclic glucans (CG) or capsular polysaccharides (KPS) were not significantly impaired in their soybean-root attachment capacity, suggesting that these surface polysaccharides might not be relevant in early attachment to soybean roots. These results also indicate that the molecular mechanisms involved in S. fredii attachment to soybean roots might be different to those operating in Bradyrhizobium japonicum. PMID:25521500

  1. FCC-hh Hadron Collider - Parameter Scenarios and Staging Options

    CERN Document Server

    Benedikt, Michael; Schulte, Daniel; Zimmermann, F; Syphers, M J

    2015-01-01

    FCC-hh is a proposed future energy-frontier hadron collider, based on dipole magnets with a field around 16 T installed in a new tunnel with a circumference of about 100 km, which would provide proton collisions at a centre-of-mass energy of 100 TeV, as well as heavy-ion collisions at the equivalent energy. The FCC-hh should deliver a high integrated proton-proton luminosity at the level of several 100 fb−1 per year, or more. The challenges for operating FCC-hh with high beam current and at high luminosity include the heat load from synchrotron radiation in a cold environment, the radiation from collision debris around the interaction region, and machine protection. In this paper, starting from the FCC-hh design baseline parameters we explore different approaches for increasing the integrated luminosity, and discuss the impact of key individual pa- rameters, such as the turnaround time. We also present some injector considerations and options for early hadron-collider operation.

  2. Optical spectroscopy of HH-exciting stars from scattered light continua

    Optical spectra of the reflected light continua visible in parts of several Herbig-Haro objects are presented. HH 100 unmistakably scatters the chromospheric spectrum of a strong emission-line T Tau star. HH 48S also reflects a T Tau stellar spectrum, as perhaps do HH 24 and HH 55, but less convincingly. HH 55 reveals photospheric absorption features too, corresponding to an M3.5 T Tau star. The continuum in HH 120 (= CG 30 HH) is unclassifiable while that in HH 46A has dimmed considerably (by a factor of order 20) although, only 7 yr ago, it clearly reflected a strong-line T Tau spectrum. It is concluded that at least some of the stars that excite Herbig-Haro nebulae, even when those stars are not directly visible, pass through a strong-line T Tau phase, and can undergo abrupt and dramatic changes in visual luminosity.

    Though family caregiving forms the backbone of the long-term care system in the United States, long-term care policies have traditionally focused on paid services that frail older people and people with disabilities utilize for their day-to-day functioning. Part of the exclusion of family caregiving from the long-term care discourse stems from the traditional separation of the private sphere, where family caregiving occurs, from the public sphere of policy making. However, the passage of the Family and Medical Leave Act (FMLA), the National Family Caregiver Support Program (NFCSP) and Medicaid waiver legislation may reflect recent changes in the government's position on their role in addressing issues related to the "private spheres." In this article, we explore the nature of family caregiving in the United States, the divide between the public and private spheres and provide an overview of family caregiving-related policies and programs in the U.S. In our review, we examine the provisions in the FMLA, NFCSP, and Medicaid waiver legislation that support family caregiving efforts. We also examine the roles of family caregiver organizations in making family caregiving an important element of long-term care policy and influencing policy-making.

    The first order considerations of the optics for the FCC-hh ring are presented. The arc cell is generated taking into account some general considerations like the whole circumference, maximum gradients and lengths of the elements in the cell. The integration of the insertion regions started. Three types of Dispersion Suppressors (DIS) are studied. The sensitivity of the arc parameters to these layout considerations is studied in more detail. An alternative layout is shown as well.

    The Multi-Object-Spectroscopy (MOS) mode of LIRIS was used to map the near-IR stellar outflow HH 223, in the dark cloud Lynds 723 (L723). HH 223 spatially coincides with the east-west component of the L723 quadrupolar CO outflow. The radio continuum source SMA2, towards the center of the quadrupolar CO outflow, hides the YSO that seems to power both the near-IR and the CO outflows. To map the S-shaped, near-IR emission of HH 223, extending ˜ 5', an appropriate mask was designed, with 16 rectangular slitlets. J, H and K-band spectra (R ˜eq 2500) were obtained through the mask. The kinematics of the neutral (H2) and ionized ([FeII]) gas outflow was derived from these data. The results confirm that both the near-IR and the CO outflows have a common driving source. To our knowledge, this is the first use of the MOS-LIRIS observing mode with the mask designed ad hoc to fit several extended, nonaligned targets.

    To evaluate the hand hygiene (HH) practices among veterinary technicians (VT) and veterinary support staff (VSS) in small animal private practice. This was a prospective questionnaire-based study involving 182 VT and VSS from 18 small animal hospitals in the USA. Questions asked included gender, number of animals handled per work shift, frequency of hand washing, reason for not washing more frequently, most common available hand washing agent, education regarding the importance of HH and frequency of ring wearing. Less than half of the respondents [76 of 182 (41·7%)] reported washing their hands regularly between handling patients and 154 of 182 (85·6%) believed they should have washed more frequently. The most commonly employed HH agent was hand soap [154 of 182 (84·6%)] and the most common reason cited for not washing more frequently was being too busy [132 of 182 (72·5%)]. Only 96 of 182 (52·7%) respondents were educated by doctors at their hospital regarding the importance of HH. The HH practices among VT and VSS in small animal private practice is poor. Hand soap was the most commonly employed agent among respondents in this study. Education of VT and VSS regarding the importance of HH requires improvement. © 2012 British Small Animal Veterinary Association.

  9. HH 1158: THE LOWEST LUMINOSITY EXTERNALLY IRRADIATED HERBIG–HARO JET

    Riaz, B. [Max-Planck-Institut für Extraterrestrische Physik, Giessenbachstrasse 1, D-85748 Garching (Germany); Whelan, E. T. [Institute für Astronomie und Astrophysik, Eberhard Karls University Tuebingen, Sand 1, D-72076 Tübingen (Germany)

    2015-12-20

    We have identified a new externally irradiated Herbig–Haro (HH) jet, HH 1158, within ∼2 pc of the massive OB type stars in the σ Orionis cluster. At an L{sub bol} ∼ 0.1 L{sub ⊙}, HH 1158 is the lowest luminosity irradiated HH jet identified to date in any cluster. Results from the analysis of high-resolution optical spectra indicate asymmetries in the brightness, morphology, electron density, velocity, and the mass outflow rates for the blue and redshifted lobes. We constrain the position angle of the HH 1158 jet at 102° ± 5°. The mass outflow rate and the mean accretion rate for HH 1158 using multiple diagnostics are estimated to be (5.2 ± 2.6) × 10{sup −10} M{sub ⊙} yr{sup −1} and (3.0 ± 1.0) × 10{sup −10} M{sub ⊙} yr{sup −1}, respectively. The properties for HH 1158 are notably similar to the externally irradiated HH 444–HH 447 jets previously identified in σ Orionis. In particular, the morphology is such that the weaker jet beam is tilted toward the massive stars, indicating a higher extent of photo-evaporation. The high value for the Hα/[S ii] ratio is also consistent with the ratios measured in other irradiated jets, including HH 444–HH 447. The presence of an extended collimated jet that is bipolar and the evidence of shocked emission knots make HH 1158 the first unique case of irradiated HH jets at the very low-luminosity end, and provides an opportunity to learn the physical properties of very faint HH jet sources.

    To assess the consequences of private outsourcing on the overall supply and filling of prescriptions in state health services. The research was conducted using quantitative and qualitative techniques in 13 states. The information was collected through interviews and direct observation. The interviews were carried on staff of state health services related to the drug supply chain and users of health services. The quantitative approach examined the percentage of stocked full recipes in a sample of users. States that have opted for the fully outsourced model, and properly monitored this choice, have increased the supply of drugs to their users and guaranteed the supply in the care units in charge. Other states with the outsourced model have multiple problems: direct purchase of drugs not included in the basic drugs catalogue, failure of suppliers and shortage of supplies in the laboratories that provide the company. The main disadvantages identified in all models were: the subordination of the medical criteria to administrative criteria, insufficient planning based on local care needs, heterogeneous procedures, insufficient knowledge of regulations and lack of normativity. The results indicate that the incorporation of private providers in the drug supply chain may not be the solution to bring down the shortage faced by health services, especially at the hospital level. The shift to outsourcing models has developed without incorporating evaluation mechanisms and the consequences that this transition can have on state health systems must be investigated more deeply.

  11. Shifts in guidelines for ethical scientific conduct: how public and private organizations create and change norms of research integrity.

    Montgomery, Kathleen; Oliver, Amalya L

    2009-02-01

    We analyze the activities and actors involved in articulating and diffusing guidelines for ethical scientific conduct from 1975 to the present. We use a theoretical framework of institutional change at the organizational-field level to examine the co-evolution of the structure of the organizational field of 'scientific research' and its institutional logic. Public agencies have long provided funding to US universities to support faculty research, expecting that implicit norms of scientific conduct would guide behavior. Growing publicity about research fraud in the late 1960s and early 1970s triggered a shift from implicit norms to explicit behavioral proscriptions, with strong administrative oversight. As private sources of research funding exert new pressures on research behavior, public-private partnerships are emerging to articulate explicit, yet voluntary prescriptive norms of research integrity. The analysis demonstrates the co-evolution and co-dependence of changes in the identity and strength of influential actors in the field of scientific research and changes in the norms of scientific conduct. We examine how the normative guidelines have been constructed over time, illustrating the persistence of earlier norms as the foundation for current guidelines. We conclude with implications for future research conduct.

    The objective of this study was to compare perceptions and barriers between Spanish-speaking and English-speaking women in public and private hospitals being treated for pelvic organ prolapse (POP). Eight focus groups, 4 in English and 4 in Spanish, were conducted at 3 institutions with care in female pelvic medicine and reconstructive surgery. Standardized questions were asked regarding patients' emotions to when they initially noticed the POP, if they sought family support, and their response to the diagnosis and treatment. Transcripts were analyzed using grounded theory qualitative methods. Thirty-three women were Spanish-speaking and 25 were English-speaking. Spanish speakers were younger (P = 0.0469) and less likely to have a high school diploma (P speaking women had more concerns that the bulge or treatments could lead to cancer, were more resistant to treatment options, and were less likely to be offered surgery. Women in the private hospital desired more information, were less embarrassed, and were more likely to be offered surgery as first-line treatment. The concept emerged that patient care for POP varied based on socioeconomic status and language and suggested the presence of disparities in care for underserved women with POP. The discrepancies in care for Spanish-speaking women and women being treated at public hospitals suggest that there are disparities in care for POP treatment for underserved women. These differences may be secondary to profit-driven pressures from private hospitals or language barriers, low socioeconomic status, low health literacy, and barriers to health care.

    The Future Circular Collider hadron-hadron (FCC-hh) design study is currently exploring different IR design possibilities including round and flat optics or different crossing schemes. The present study intends to evaluate each scenario from the beam-beam effects point of view. In particular the single particle long term stability to maximize beam lifetimes and luminosity reach is used to quantify the differences. The impact of strong head on interactions on the beam quality and lifetime is addressed by means of GPU accelerated simulations code featuring a weak-strong 6-dimensional beam-beam interaction.

    2004-05-01

    The concept of continuous and global care is acknowledged today by all as inherent to modern medicine. A working group gathered to propose models for the coordination of supportive care for all severe illnesses in the various private and public health care centres. The supportive care are defined as: "all care and supports necessary for ill people, at the same time as specific treatments, along all severe illnesses". This definition is inspired by that of "supportive care" given in 1990 by the MASCC (Multinational Association for Supportive Care in Cancer): "The total medical, nursing and psychosocial help which the patients need besides the specific treatment". It integrates as much the field of cure with possible after-effects as that of palliative care, the definition of which is clarified (initial and terminal palliative phases). Such a coordination is justified by the pluridisciplinarity and hyperspecialisation of the professionals, by a poor communication between the teams, by the administrative difficulties encountered by the teams participating in the supportive care. The working group insists on the fact that the supportive care is not a new speciality. He proposes the creation of units. departments or pole of responsibility of supportive care with a "basic coordination" involving the activities of chronic pain, palliative care, psycho-oncology, and social care. This coordination can be extended, according to the "history" and missions of health care centres. Service done with the implementation of a "unique counter" for the patients and the teams is an important point. The structure has to comply with the terms and conditions of contract (Consultation, Unit or Centre of chronic pain, structures of palliative care, of psycho-oncology, of nutrition, of social care). A common technical organization is one of the interests. The structure has to set up strong links with the private practitioners, the networks, the home medical care (HAD) and the nurses

    2007-01-01

    We present new, very late-time optical photometry and spectroscopy of the interesting Type II-P supernova, SN 2002hh, in NGC 6946. Gemini/GMOS-N has been used to acquire visible spectra at six epochs between 2004 August and 2006 July, following the evolution of the SN from age 661 to 1358 days. Few optical spectra of Type II supernovae with ages greater than one year exist. In addition, g'r'i' images were acquired at all six epochs. The spectral and photometric evolution of SN 2002hh has been very unusual. Measures of the brightness of this SN, both in the R and I bands as well as in the H-alpha emission flux, show no significant fading over an interval of nearly two years. The most straightforward explanation for this behavior is that the light being measured comes not only from the SN itself but also from an echo off of nearby dust. Echoes have been detected previously around several SNe but these echoes, at their brightest, were ~8 mag below the maximum brightness of the SN. At V~21 mag, the putative echo ...

  20. Models for the Infrared Cavity of HH 46/47

    2004-01-01

    We have modeled the limb-brightened cavity seen in the new Spitzer Space Telescope IR images of the southwest lobe of HH 46/47 as the bow shock driven by an outflow from a young, low-mass star. We present models in which the outflow is a perfectly collimated, straight jet, models in which the jet precesses, and finally a model in which the outflow takes the form of a latitude-dependent wind. We study cases in which the outflow moves into a constant-density cloud and into a stratified cloud. We find that the best agreement with the observed cavity is obtained for the precessing jet in a stratified cloud. However, the straight jet (traveling in a stratified cloud) also gives cavity shapes close to the observed one. The latitude-dependent wind model that we have computed gives cavity shapes that are substantially wider than the observed cavity. We therefore conclude that the cavity seen in the Spitzer observations of the southwest lobe of the HH 46/47 outflow do not seem to imply the presence of a latitude-dependent wind, as it can be modeled successfully with a perfectly collimated jet model.

    We have identified a new externally irradiated Herbig-Haro (HH) jet, HH 1158, within ~2 pc of the massive OB type stars in the sigma Orionis cluster. At an Lbol ~ 0.1 Lsun, HH 1158 is the lowest luminosity irradiated HH jet identified to date in any cluster. Results from the analysis of high-resolution optical spectra indicate asymmetries in the brightness, morphology, electron density, velocity, and the mass outflow rates for the blue and red-shifted lobes. We constrain the position angle of the HH 1158 jet at 102+/-5 degree. The mass outflow rate and the mean accretion rate for HH 1158 using multiple diagnostics are estimated to be (5.2 +/- 2.6) x 10^(-10) Msun/yr and (3.0 +/- 1.0) x 10^(-10) Msun/yr, respectively. The properties for HH 1158 are notably similar to the externally irradiated HH 444 -- HH 447 jets previously identified in sigma Orionis. In particular, the morphology is such that the weaker jet beam is tilted towards the massive stars, indicating a higher extent of photo-evaporation. The high v...

    The 2010 Affordable Care Act's (ACA) aims of lowering costs and improving quality of care will renew focus on preventive health strategies. This coincides with a trend in medicine to reconsider population health approaches as part of the standard curriculum. This intersection of new policy and educational climates presents a unique opportunity to reconsider traditional healthcare structures. This paper introduces and advances an alignment that few have considered. We propose that accountable care organizations (ACOs), which are expected to proliferate under the ACA, present the best opportunity to establish partnerships between healthcare, public health, and community-based organizations to achieve the legislation's goals. One example is encouraging daily physical activity via built environment interventions and programs, which is recommended by numerous groups. We highlight how nonprofit organizations in Sacramento, California have been able to leverage influence, capital, and policy to encourage design for active living, and how their work is coordinating with public health and healthcare initiatives. In conclusion, we critically examine potential barriers to the success of partnerships between ACOs and community organizations and encourage further exploration and evaluation.

    We study the pair production of charged Higgs bosons at the CERN Large Hadron Collider in the context of the minimal supersymmetric extension of the standard model. We compare the contributions due to qq-bar annihilation at the tree level and gg fusion, which proceeds at one loop. At small or large values of tan(beta), H^+H^- production proceeds dominantly via bb-bar annihilation, due to Feynman diagrams involving neutral CP-even Higgs bosons and top quarks, which come in addition to the usually considered Drell-Yan diagrams. In the case of gg fusion, the squark loop contributions may considerably enhance the well-known quark loop contributions.

    We present new Hubble Space Telescope (HST) narrow band images of the bright Herbig–Haro (HH) objects HH 1 and 2 in the light of the Hα, Hβ, [O i] 6300, [O ii] 3726+28, [O iii] 5007 and [S ii] 6716+30 emission lines. The resulting emission and line ratio maps give an improved picture of the physical structure of these HH objects, showing the presence of spatially limited, high excitation/ionization ridges. We find that HH 1 has a morphology that could be interpreted in terms of a single, asymmetric bow shock, and that many of the clumps of HH 2 fall in two bow-shaped structures of different excitations. We also construct two-line ratio plots showing clear trends, which are much simpler than the highly complex spatial distributions of the emission, and are therefore interesting for testing shock models of HH objects (we only present a comparison with previously published, steady plane-parallel shock models). We have also used the temperature-sensitive [O i]/[S ii] line ratio to evaluate the temperature range and to obtain temperature maps of HH 1 and 2. We find that this line ratio picks out emitting regions with temperatures ≈10{sup 4} K, except along the leading edges of the HH 1 and 2 bow shocks (in which temperatures of ∼3 → 5 × 10{sup 4} K are obtained)

    There are conflicting data about the correlation between hyperhidrosis (HH) and anxiety and depression. We sought to determine the prevalence of anxiety and depression in patients with or without HH. We examined 2017 consecutive dermatology outpatients from Vancouver, British Columbia, Canada, and Shanghai, China, using Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 scales for anxiety and depression assessments. Multivariable logistic regression analysis was performed to evaluate if the impact of HH on anxiety and depression is dependent on demographic factors and diagnoses of the patients' presenting skin conditions. The prevalence of anxiety and depression was 21.3% and 27.2% in patients with HH, respectively, and 7.5% and 9.7% in patients without HH, respectively (P value anxiety and depression. Multivariable analysis showed that HH-associated increase in anxiety and depression prevalence is independent of demographic factors and presenting skin conditions. The data from the questionnaires relied on the accuracy of patients' self-reports. Both single variant and multivariable analyses showed a significant association between HH and the prevalence of anxiety and depression in a HH severity-dependent manner.

    The hedgehog (Hh) pathway is a developmental signaling pathway that is essential to the proper embryonic development of many vertebrate systems. Dysregulation of Hh signaling has been implicated as a causative factor in the development and progression of several forms of human cancer. As such, the development of small molecule inhibitors of Hh signaling as potential anti-cancer chemotherapeutics has been a major area of research interest in both academics and industry over the past ten years. Through these efforts, synthetic small molecules that target multiple components of the Hh pathway have been identified and advanced to preclinical or clinical development. The goal of this review is to provide an update on the current status of several synthetic small molecule Hh pathway inhibitors and explore the potential of several recently disclosed inhibitory scaffolds.

    Full Text Available In many countries, anti-crisis public measures focus on higher public investment or investment in public objectives, like investment in infrastructure projects, as an important mean to maintain economic activity during the crisis and support a rapid return to sustained economic growth. An instrument to realize these investments is the Public-Private Partnership (hereinafter PPP.Nevertheless, PPP’s are vulnerable to the economic impact of the crisis. Although the final consequences and duration of the crisis are not yet known, the effects on PPP’s can already be identified and estimated. The crisis has made the conditions for this instrument more difficult. Despite some signs of recovery, the volumes and values of the PPP projects currently closing is still significantly below the level reached before the crisis.The topic of PPP financing has never been more important than under the current crisis. Alternative innovative solutions are being sought, new markets need to be opened in order to enable the further development of PPP, the stakeholder organizations have to increase their level of understanding regarding the new environment for PPP.

    Abdominal pain is a critical clinical symptom in pancreatic cancer (PC) that affects the quality of life for PC patients. However, the pathogenesis of PC pain is largely unknown. In this study, we show that PC pain is initiated by the sonic hedgehog (sHH) signaling pathway in pancreatic stellate cells (PSCs), which is activated by sHH secreted from PC cells, and then, neurotrophic factors derived from PSCs mediate the pain. The different culture systems were established in vitro, and the expression of sHH pathway molecules, neurotrophic factors, TRPV1, and pain factors were examined. Capsaicin-evoked TRPV1 currents in dorsal root ganglion (DRG) neurons were examined by the patch-clamp technique. Pain-related behavior was observed in an orthotopic tumor model. sHH and PSCs increased the expression and secretion of TRPV1, SP, and CGRP by inducing NGF and BDNF in a co-culture system, also increasing TRPV1 current. But, suppressing sHH pathway or NGF reduced the expression of TRPV1, SP, and CGRP. In vivo, PSCs and PC cells that expressed high levels of sHH could enhance pain behavior. Furthermore, the blockade of NGF or TRPV1 significantly attenuated the pain response to mechanical stimulation compared with the control. Our results demonstrate that sHH signaling pathway is involved in PC pain, and PSCs play an essential role in the process greatly by inducing NGF.

    The morphology, kinematics and entrainment mechanism of the HH 46/47 molecular outflow were studied using new ALMA Cycle 0 observations. Results show that the blue and red lobes are strikingly different. We argue that these differences are partly due to contrasting ambient densities that result in different wind components having a distinct effect on the entrained gas in each lobe. A 29-point mosaic, covering the two lobes at an angular resolution of about 3", detected outflow emission at much higher velocities than previous observations, resulting in significantly higher estimates of the outflow momentum and kinetic energy than previous studies of this source, using the CO(1-0) line. The morphology and the kinematics of the gas in the blue lobe are consistent with models of outflow entrainment by a wide-angle wind, and a simple model may describe the observed structures in the position-velocity diagram and the integrated intensity map. The red lobe exhibits a more complex structure, and there is evidence tha...

    Using the High Dispersion Spectrograph at the Subaru Telescope, echelle spectra of two giant arcs, i.e. nebulosities Cw and L associated with HH 131 in Orion are presented. Typical emission lines of Herbig-Haro objects have been detected towards Cw. With the 2.16 m telescope of National Astronomical Observatories, spectra of Nebu. C, L and K are obtained, which also show strong [SII]6717/6731, H$\\alpha$ and [NII]6583 emission lines. Position-velocity distributions of Cw and L are analyzed. The fastest radial velocity of Cw is V_r ~ -18.0 km/s. When the flow at L goes to the south, it slows down. The fastest radial velocity of L has been observed of -45.0 km/s and the slowest value is about -18.3 km/s. The similarity of the velocities and their positional connection indicate that Cw and L are physically associated. The entire flow tends to become less excited and less ionized when going further to the south (i.e., from Nebu. K, L to C). The electron densities of all the observed nebulosities are low (n_e ~ 10^...

    The comparative studies on grading in subarachnoid hemorrhage (SAH) had several limitations such as the unclear grading of Glasgow Coma Scale 15 with neurological deficits in World Federation of Neurosurgical Societies (WFNS), and the inclusion of systemic disease in Hunt and Hess (H&H) scales. Their differential incremental impacts and optimum cut-off values for unfavourable outcome are unsettled. This is a prospective comparison of prognostic impacts of grading schemes to address these issues. SAH patients were assessed using WFNS, H&H (including systemic disease), modified H&H (sans systemic disease) and followed up with Glasgow Outcome Score (GOS) at 3 months. Their performance characteristics were analysed as incremental ordinal variables and different grading scale dichotomies using rank-order correlation, sensitivity, specificity, positive predictive value, negative predictive value, Youden's J and multivariate analyses. A total of 1016 patients were studied. As univariate incremental variable, H&H sans systemic disease had the best negative rank-order correlation coefficient (-0.453) with respect to lower GOS (p H&H sans systemic disease had the greatest adjusted incremental impact of 0.72 (95% confidence interval (CI) 0.54-0.91) against a lower GOS as compared to 0.6 (95% CI 0.45-0.74) and 0.55 (95% CI 0.42-0.68) for H&H and WFNS grades, respectively. In multivariate categorical analysis, H&H grades 4-5 sans systemic disease had the greatest impact on unfavourable GOS with an adjusted odds ratio of 6.06 (95% CI 3.94-9.32). To conclude, H&H grading sans systemic disease had the greatest impact on unfavourable GOS. Though systemic disease is an important prognostic factor, it should be considered distinctly from grading. Appropriate cut-off values suggesting unfavourable outcome for H&H and WFNS were 4-5 and 3-5, respectively, indicating the importance of neurological deficits in addition to level of consciousness.

    The morphology, kinematics, and entrainment mechanism of the HH 46/47 molecular outflow were studied using new ALMA Cycle 0 observations. Results show that the blue and red lobes are strikingly different. We argue that these differences are partly due to contrasting ambient densities that result in different wind components having a distinct effect on the entrained gas in each lobe. A 29 point mosaic, covering the two lobes at an angular resolution of about 3'', detected outflow emission at much higher velocities than previous observations, resulting in significantly higher estimates of the outflow momentum and kinetic energy than previous studies of this source, using the CO(1-0) line. The morphology and the kinematics of the gas in the blue lobe are consistent with models of outflow entrainment by a wide-angle wind, and a simple model describes the observed structures in the position-velocity diagram and the velocity-integrated intensity maps. The red lobe exhibits a more complex structure, and there is evidence that this lobe is entrained by a wide-angle wind and a collimated episodic wind. Three major clumps along the outflow axis show velocity distribution consistent with prompt entrainment by different bow shocks formed by periodic mass ejection episodes which take place every few hundred years. Position-velocity cuts perpendicular to the outflow cavity show gradients where the velocity increases toward the outflow axis, inconsistent with outflow rotation. Additionally, we find evidence for the existence of a small outflow driven by a binary companion.

    We study archival HST [S II] 6716+30 and H{alpha} images of the HH 34 outflow, taken in 1998.71 and in 2007.83. The {approx}9 yr time baseline and the high angular resolution of these observations allow us to carry out a detailed proper-motion study. We determine the proper motions of the substructure of the HH 34S bow shock (from the [S II] and H{alpha} frames) and of the aligned knots within {approx}30'' from the outflow source (only from the [S II] frames). We find that the present-day motions of the knots along the HH 34 jet are approximately ballistic, and that these motions directly imply the formation of a major mass concentration in {approx}900 yr, at a position similar to the one of the present-day HH 34S bow shock. In other words, we find that the knots along the HH 34 jet will merge to form a more massive structure, possibly resembling HH 34S.

  19. Molecular observations of HH34 - Does NH3 accurately trace dense molecular gas near young stars?

    Davis, C. J.; Dent, W. R. F.

    1993-03-01

    Single-dish observations in HCO(+) J = 4-3 are presented of the regions around HH34 and around HH34IRS. The former is one of the best examples of the association between Herbig-Haro shocks, optical jets, and young stellar objects. The HCO(+) and CS maps peak toward the outflow source HH34IRS and suggest the presence of a hot dense molecular core. The NH3 is confined to a peak about 4-0 arcsec east of HH34IRS and to a ridge which extends in a north-south direction and peaks about 20 arcsec south of the end of the optical jet. Thus, the NH3 observations do not trace the underlying gas density and temperature in this outflow source. Toward HH34IRS the NH3 column density is less by a factor of about 10 than toward the NH3 peak position is the HH34 region, providing evidence that the NH3 is underabundant towards the central exciting stars. This underabundance may explain the toroidal structures often seen in NH3 observations of other outflow sources.

    The radio-knots of the Herbig–Haro (HH) 80/81/80N jet extend from the HH 80 object to the recently discovered Source 34 and has a total projected jet size of 10.3 pc, constituting the largest collimated radio-jet system known so far. It is powered by the bright infrared source IRAS 18162−2048 associated with a massive young stellar object. We report 6 cm JVLA observations that, compared with previous 6 cm VLA observations carried out in 1989, allow us to derive proper motions of the HH 80, HH 81, and HH 80N radio knots located about 2.5 pc away in projection from the powering source. For the first time, we measure proper motions of the optically obscured HH 80N object providing evidence that this knot, along with HH 81 and HH 80 are associated with the same radio-jet. We also confirm the presence of Source 34, located further north of HH 80N, previously proposed to belong to the jet.We derived that the tangential velocity of HH 80N is 260 km s{sup −1} and has a direction in agreement with the expected direction of a ballistic precessing jet. The HH 80 and HH 81 objects have tangential velocities of 350 and 220 km s{sup −1}, respectively, but their directions are somewhat deviated from the expected jet path. The velocities of the HH objects studied in this work are significantly lower than those derived for the radio knots of the jet close to the powering source (600–1400 km s{sup −1}) suggesting that the jet is slowing down due to a strong interaction with the ambient medium. As a result, since HH 80 and HH 81 are located near the edge of the cloud, the inhomogeneous and low density medium may contribute to skew the direction of their determined proper motions. The HH 80 and HH 80N emission at 6 cm is, at least in part, probably synchrotron radiation produced by relativistic electrons in a magnetic field of 1 mG. If these electrons are accelerated in a reverse adiabatic shock, we estimate a jet total density of ≲1000 cm{sup −3}. All of these

    We present a series of molecular hydrogen images of the Herbig-Haro 1-2 system in the 1-0 S(1) transition at 2.121 microns, with a spatial resolution of approximately 2 sec. The distribution of H2 is then compared with that of the excitation, given by the (S II) 6717+6731 to H-alpha line ratio. We find that most optical condensations in the HH 1-2 system, including the VLA 1 jet, have H2 counterparts. H2 emission is detected in most low excitation knots, as expected for low velocity shocks (50 km/s less than), but also in high excitation regions, like in HH 1F and HH 2A min. For these latter objects, the H2 emission could be due to the interaction of the preionizing flux, produced by 150-200 km/s shocks, with the surrounding interstellar matter, i.e., fluorescence. The lack fluorescent lines in the ultraviolet (UV), however, suggest a different mechanism. H2 is detected at the tip of the VLA 1 jet, where the knot morphology suggests the presence of a second bow shock. H2 is detected also SE of HH 2E and SW of HH 1F, in regions with known NH3 emission.

    Sinorhizobium fredii HH103 is a fast-growing rhizobial strain infecting a broad range of legumes including both American and Asiatic soybeans. In this work, we present the sequencing and annotation of the HH103 genome (7.25 Mb), consisting of one chromosome and six plasmids and representing the structurally most complex sinorhizobial genome sequenced so far. Comparative genomic analyses of S. fredii HH103 with strains USDA257 and NGR234 showed that the core genome of these three strains contains 4,212 genes (61.7% of the HH103 genes). Synteny plot analysis revealed that the much larger chromosome of USDA257 (6.48 Mb) is colinear to the HH103 (4.3 Mb) and NGR324 chromosomes (3.9 Mb). An additional region of the USDA257 chromosome of about 2 Mb displays similarity to plasmid pSfHH103e. Remarkable differences exist between HH103 and NGR234 concerning nod genes, flavonoid effect on surface polysaccharide production, and quorum-sensing systems. Furthermore a number of protein secretion systems have been found. Two genes coding for putative type III-secreted effectors not previously described in S. fredii, nopI and gunA, have been located on the HH103 genome. These differences could be important to understand the different symbiotic behavior of S. fredii strains HH103, USDA257, and NGR234 with soybean.

  9. Quantitative analysis of privatization

    CERN Document Server

    Vahabi, M

    2008-01-01

    In recent years, the economic policy of privatization, which is defined as the transfer of property or responsibility from public sector to private sector, is one of the global phenomenon that increases use of markets to allocate resources. One important motivation for privatization is to help develop factor and product markets, as well as security markets. Progress in privatization is correlated with improvements in perceived political and investment risk. Many emerging countries have gradually reduced their political risks during the course of sustained privatization. In fact, most risk resolution seems to take place as privatization proceeds to its later stage. Alternative benefits of privatization are improved risk sharing and increased liquidity and activity of the market. One of the main methods to develop privatization is entering a new stock to the markets for arising competition. However, attention to the capability of the markets to accept a new stock is substantial. Without considering the above st...

  10. First Design of a Proton Collimation System for 50 TeV FCC-hh

    Fiascaris, Maria; Mirarchi, Daniele; Redaelli, Stefano

    2016-01-01

    We present studies aimed at defining a first conceptual solution for a collimation system for the hadron-hadron option for the Future Circular Collider (FCC-hh). The baseline collimation layout is based on the scaling of the present LHC collimation system to the FCC-hh energy. It currently includes a dedicated betatron cleaning insertion as well as collimators in the experimental insertions to protect the inner triplets. An aperture model for the FCC-hh is defined and the geometrical acceptance is calculated at top energy taking into account mechanical and optics imperfections. Based on these studies the collimator settings needed to protect the machine are defined. The performance of the collimation system is then assessed with particle tracking simulation tools assuming a perfect machine.

    2017-01-01

    Debris from 50 TeV proton-proton collisions at the main interaction point in the FCC-hh may contribute to the background in the subsequent detector. This cross-talk is of possible concern for the FCC-hh due to the high luminosity and energy of the collider. DPMJET-III is used as a collision debris generator in order to assess the muon cross-talk contribution. An analytical calculation of muon range in rock is performed. This is followed by a full Monte Carlo simulation using FLUKA, where the accelerator tunnel has been modelled. The muon cross talk between the adjacent interaction points is assessed and its implications for FCC-hh design are discussed.

    In this document we study the effect of anomalous Higgs boson couplings on non-resonant pair production of Higgs bosons (HH) at the LHC. We explore the space of the five parameters $\\kappa_\\lambda$, $\\kappa_t$, $c_2$, $c_{g}$, and $c_{2g}$ in terms of the corresponding kinematics of the final state, and describe a suggested partition of the space into a limited number of regions featuring similar phenomenology in the kinematics of HH final state, along with a corresponding set of representative benchmark points. We also provide an analytical parametrization of the cross-section modifications that the variation of anomalous couplings produces with respect to standard model HH production along with a recipe to translate our results into other parameter-space bases. Finally, we provide a preliminary analysis of variations in the topology of the final state within each region based on recent LHC results.

    We present new Hα and Hβ images of the HH 1/2 system, and we find that the Hα/Hβ ratio has high values in ridges along the leading edges of the HH 1 bow shock and of the brighter condensations of HH 2. These ridges have Hα/Hβ = 4 → 6, which is consistent with collisional excitation from the n = 1 to the n = 3 and 4 levels of hydrogen in a gas of temperatures T = 1.5 → 10 × 10{sup 4} K. This is therefore the first direct evidence that the collisional excitation/ionization region of hydrogen just behind Herbig-Haro shock fronts is detected.

    2004-01-01

    A study of Hodgkin-Huxley (HH) neuron under external sinusoidal excited stimulus is presented in this paper. As is well known, the stimulus frequency is to be considered as a bifurcate parameter, and numerous phenomena, such as synchronization, period, and chaos appear alternatively with the changing of the stimulus frequency. For the stimulus frequency less than 2fB (fB being the base frequency in this paper), the simulation results demonstrate that the single HH neuron could completely convey the sinusoidal signal in anti-phase into interspike interval (ISI) sequences. We also report, perhaps for the first time, another kind of phenomenon, the beat phenomenon, which exists in the phase dynamics of the ISI sequences of the HH neuron stimulated by a sinusoidal current. It is shown furthermore that intermittent transition results in the general route to chaos.

    The FCC-hh (Future Hadron-Hadron Circular Collider) is one of the three options considered for the next generation accelerator in high-energy physics as recommended by the European Strategy Group. The layout of FCC-hh has been optimized to a more compact design following recommendations from civil engineering aspects. The updates on the first order and second order optics of the ring will be shown for collisions at the required centre-of-mass energy of 100 TeV. Special emphasis is put on the dispersion suppressors and general beam cleaning sections as well as first considerations of injection and extraction sections.

    We study the sensitivity of the process $\\mu^-\\mu^+\\to HH$ to the $q^2$-dependence of the $HHH$ form factor, which can reflect the Higgs boson structure, especially in the case of compositeness. We compute the Born and 1 loop SM contribution to this process. We then show how the $\\mu^-\\mu^+\\to HH$ polarized and unpolarized cross sections are modified by the presence of various types of anomalous contributions to the $HHH$ form factor, in particular Higgs constituents in the case of compositeness.

    Full Text Available NS5B is pivotal RNA dependent RNA polymerase (RdRp of HCV and NS5B function interfering halts the virus infective cycle. This work aimed to produce cell penetrable humanized single domain antibodies (SdAb; VH/V(HH that interfere with the RdRp activity. Recombinant NS5BΔ55 of genotype 3a HCV with de novo RNA synthetic activity was produced and used in phage biopanning for selecting phage clones that displayed NS5BΔ55 bound VH/V(HH from a humanized-camel VH/V(HH display library. VH/V(HH from E. coli transfected with four selected phage clones inhibited RdRp activity when tested by ELISA inhibition using 3'di-cytidylate 25 nucleotide directed in vitro RNA synthesis. Deduced amino acid sequences of two clones showed V(HH hallmark and were designated V(HH6 and V(HH24; other clones were conventional VH, designated VH9 and VH13. All VH/V(HH were linked molecularly to a cell penetrating peptide, penetratin. The cell penetrable VH9, VH13, V(HH6 and V(HH24 added to culture of Huh7 cells transfected with JHF-1 RNA of genotype 2a HCV reduced the amounts of RNA intracellularly and in culture medium implying that they inhibited the virus replication. VH/V(HH mimotopes matched with residues scattered on the polymerase fingers, palm and thumb which were likely juxtaposed to form conformational epitopes. Molecular docking revealed that the antibodies covered the RdRp catalytic groove. The transbodies await further studies for in vivo role in inhibiting HCV replication.

  7. HH-MIP: An Enhancement of Mobile IP by Home Agent Handover

    Directory of Open Access Journals (Sweden)

    Jeng-Yueng Chen

    2010-01-01

    Full Text Available We propose an enhancement of Mobile IP (MIP called MIP with Home Agent Handover (HH-MIP to enjoy most of the advantages of Route Optimization MIP (ROMIP but with only a small increase of signaling overhead. In HH-MIP, the concept of Temporary HA (THA is proposed and the mobile host (MH registers the new CoA with its THA rather than its original HA. Since the THA of an MH is selected to be close to the current location of MH, HH-MIP reduces the handoff latency and shortens the signaling path of registration as well. Moreover, HH-MIP adopts an aggressive approach in selecting THA for an MH, that is, whenever an MH is moving away from its HA or previous THA, the MH triggers the handover of THA. Theoretical analysis demonstrates that the proposed scheme enjoys small handoff latency as well as routing efficiency, and the signaling cost of the proposed scheme is significantly less than that in ROMIP.

    2005-12-01

    Fibroblast growth factor (Fgf) signaling plays important roles in brain development. Fgf3 and Fgf8 are crucial for the formation of the forebrain and hindbrain. Fgf8 is also required for the midbrain to form. Here, we identified zebrafish Fgf19 and examined its roles in brain development by knocking down Fgf19 function. We found that Fgf19 expressed in the forebrain, midbrain and hindbrain was involved in cell proliferation and cell survival during embryonic brain development. Fgf19 was also essential for development of the ventral telencephalon and diencephalon. Regional specification is linked to cell type specification. Fgf19 was also essential for the specification of gamma-aminobutyric acid (GABA)ergic interneurons and oligodendrocytes generated in the ventral telencephalon and diencephalon. The cross talk between Fgf and Hh signaling is critical for brain development. In the forebrain, Fgf19 expression was down-regulated on inhibition of Hh but not of Fgf3/Fgf8, and overexpression of Fgf19 rescued partially the phenotype on inhibition of Hh. The present findings indicate that Fgf19 signaling is crucial for forebrain development by interacting with Hh and provide new insights into the roles of Fgf signaling in brain development.

    2016-01-01

    We have analyzed four epochs of H$\\alpha$ and [S~II] HST images of the HH~1/2 outflow (covering a time interval from 1994 to 2014) to determine proper motions and emission line fluxes of the knots of HH~2. We find that our new proper motions agree surprisingly well with the motions measured by Herbig \\& Jones (1981), although there is partial evidence for a slight deceleration of the motion of the HH~2 knots from 1945 to 2014. We also measure the time-variability of the H$\\alpha$ intensities and the [S~II]/H$\\alpha$ line ratios, and find that knots H and A have the largest intensity variabilities (in $1994\\to 2014$). Knot H (which now dominates the HH~2 emission) has strengthened substantially, while keeping an approximately constant [S~II]/H$\\alpha$ ratio. Knot A has dramatically faded, and at the same time has had a substantial increase in its [S~II]/H$\\alpha$ ratio. Possible interpretations of these results are discussed.

    The human XPF-ERCC1 protein complex plays an essential role in nucleotide excision repair by catalysing positioned nicking of a DNA strand at the 5' side of the damage. We have recently solved the structure of the heterodimeric complex of the C-terminal domains of XPF and ERCC1 (Tripsianes et al., Structure 2005;13:1849-1858). We found that this complex comprises a pseudo twofold symmetry axis and that the helix-hairpin-helix motif of ERCC1 is required for DNA binding, whereas the corresponding domain of XPF is functioning as a scaffold for complex formation with ERCC1. Despite the functional importance of heterodimerization, the C-terminal domain of XPF can also form homodimers in vitro. We here compare the stabilities of homodimeric and heterodimeric complexes of the C-terminal domains of XPF and ERCC1. The higher stability of the XPF HhH complexes under various experimental conditions, determined using CD and NMR spectroscopy and mass spectrometry, is well explained by the structural differences that exist between the HhH domains of the two complexes. The XPF HhH homodimer has a larger interaction interface, aromatic stacking interactions, and additional hydrogen bond contacts as compared to the XPF/ERCC1 HhH complex, which accounts for its higher stability.

    Mutations in the DAX1 locus cause X-linked adrenal hypoplasia congenita (AHC) and hypogonadotropic hypogonadism (HH), which manifest with primary adrenal insufficiency and incomplete or absent sexual maturation, respectively. The associated defects in spermatogenesis can range from spermatogenic arrest to Sertoli cell only syndrome. Conclusions from Dax1 knockout mouse models provide only limited insight into AHC/HH disease mechanisms, because mouse models exhibit more extensive abnormalities in testicular development, including disorganized and incompletely formed testis cords with decreased number of peritubular myoid cells and male-to-female sex reversal. We previously reported successful clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9)-mediated genome targeting in cynomolgus monkeys. Here, we describe a male fetal monkey in which targeted genome editing using CRISPR/Cas9 produced Dax1-null mutations in most somatic tissues and in the gonads. This DAX1-deficient monkey displayed defects in adrenal gland development and abnormal testis architecture with small cords, expanded blood vessels and extensive fibrosis. Sertoli cell formation was not affected. This phenotype strongly resembles findings in human patients with AHC-HH caused by mutations in DAX1. We further detected upregulation of Wnt/β-catenin-VEGF signaling in the fetal Dax1-deficient testis, suggesting abnormal activation of signaling pathways in the absence of DAX1 as one mechanism of AHC-HH. Our study reveals novel insight into the role of DAX1 in HH and provides proof-of-principle for the generation of monkey models of human disease via CRISPR/Cas9-mediated gene targeting.

    Directory of Open Access Journals (Sweden)

    Christoph Englert

    2015-04-01

    Full Text Available Searches for multi-Higgs final states allow to constrain parameters of the SM (or extensions thereof that directly relate to the mechanism of electroweak symmetry breaking. Multi-Higgs production cross sections, however, are small and the phenomenologically accessible final states are challenging to isolate in the busy multi-jet hadron collider environment of the LHC run 2 and HL-LHC. This makes the necessity to extend the list of potentially observable production mechanisms obvious. Most of the phenomenological analyses in the past have focused on gg→hh+jets; in this paper we study pp→tt¯hh at the HL-LHC and find that this channel for h→bb¯ and semi-leptonic and hadronic top decays has the potential to provide an additional handle to constrain the Higgs trilinear coupling in a global fit at the end of the high luminosity phase.

    A higher-energy circular proton collider is generally considered to be the only path available in this century for exploring energy scales well beyond the reach of the Large Hadron Collider (LHC) presently in operation at CERN. In response to the 2013 Update of the European Strategy for Particle Physics and aligned with the 2014 US ``P5'' recommendations, the international Future Circular Collider (FCC) study, hosted by CERN, is designing such future frontier hadron collider. This so-called FCC-hh will provide proton-proton collisions at a centre-of-mass energy of 100 TeV, with unprecedented luminosity. The FCC-hh energy goal is reached by combining higher-field, 16 T magnets, based on Nb3Sn superconductor, and a new 100 km tunnel connected to the LHC complex. In addition to the FCC-hh proper, the FCC study is also exploring the possibility of a High-Energy LHC (HE-LHC), with a centre-of-mass energy of 25-27 TeV, as could be achieved in the existing 27 km LHC tunnel using the FCC-hh magnet technology. A separate design effort centred at IHEP Beijing aims at developing and constructing a similar collider in China, with a smaller circumference of about 54 km, called SPPC. Assuming even higher-field 20 T magnets, by relying on high-temperature superconductor, the SPPC could reach a c.m. energy of about 70 TeV. This presentation will report the motivation and the present status of the R&D for future hadron colliders, a comparison of the three designs under consideration, the major challenges, R&D topics, the international technology programs, and the emerging global collaboration.

    在大学法人化发展的当下,公法人是世界多数国家公立大学组织形态的定位与选择。我国现行法将公立大学定性为事业单位法人,从而将其纳入私法范畴,并由私法加以规范和调整,由此形成了我国公立大学的私法人定位。但是,我国公立大学事业单位法人之定位不仅与我国公立大学多依公法命令设立的依据不符,又无法呼应公法与私法、公法人与私法人之界分,更无法避免其遁入私法,从而造成影响公立大学教育功能实现之不利后果。因此,借鉴他国公立大学组织形态之公法人模式,完成私法人向公法人的定位转向,无疑是我国公立大学组织形态变革的应然选择。在此基础上,寻求公立大学作为独立人格者及其与政府关系上的更大独立性,以此确保我国公立大学高等教育职能的实现和我国高等教育事业的发展。%Public legal person has become the major organization form in most countries,during the trend of corporation management of university. In current laws,public university is listed in legal person of public in-stitutions,so it should be adjusted and standardized under private law,thus forming its private corporation. However,the positioning of legal entity for public university as institutions neither conform to its establishment of legislative basis,nor can be distinct itself from public or private legal person,so public university fails to be restricted by private law,thus affecting their education function. Therefore,the paper draws the mode of pub-lic legal entity from university of other countries and expects the changes of positioning private to public legal entity,which is bound to become the necessity of organization form reform among our public universities. And based on the changes,public universities should chase more independency from government as an independent entity,so as to ensure the realization of functions and

    The mechanisms leading to the formation of disks around young stellar objects (YSOs) and to the launching of the associated jets are crucial to the understanding of the earliest stages of star and planet formation. HH 212 is a privileged laboratory to study a pristine jet-disk system. Therefore we investigate the innermost region ($<100$ AU) around the HH 212-MM1 protostar through ALMA band\\,7 observations of methanol. The 8 GHz bandwidth spectrum towards the peak of the continuum emission of the HH 212 system reveals at least 19 transitions of methanol. Several of these lines (among which several vibrationally excited lines in the v$_{\\rm t}=1,2$ states) have upper energies above 500 K. They originate from a compact ($<135$ AU in diameter), hot ($\\sim 295$ K) region elongated along the direction of the SiO jet. We performed a fit in the $uv$ plane of various velocity channels of the strongest high-excitation lines. The blue- and red-shifted velocity centroids are shifted roughly symmetrically on either...

  12. A study of the wiggle morphology of HH 211 through numerical simulations

    2016-01-01

    Recent high-resolution high-sensitivity observations of protostellar jets have shown many to possess deviations to their trajectories. HH 211 is one such example where sub-mm observations with the SMA have revealed a clear reflection-symmetric wiggle. The most likely explanation is that the HH 211 jet source could be moving as part of a protobinary system. Here we test this assumption by simulating HH 211 through 3D hydrodynamic jet propagation simulations using the PLUTO code with a molecular chemistry and cooling module, and initial conditions based on an analytical model derived from SMA observations. Our results show the reflection-symmetric wiggle can be recreated through the assumption of a jet source perturbed by binary motion at its base, and that a regular sinusoidal velocity variation in the jet beam can be close to matching the observed knot pattern. However, a more complex model with either additional heating from the protostar, or a shorter period velocity pulsation may be required to account for...

    We report the discovery of flip-flop activity in a W UMa-type binary. A long-term multi-color photometric surveillance of HH UMa was carried out with three sets of light curves obtained over six weeks. The light curves of the eclipsing binary presented marked asymmetry and rapid interchange between the two light maxima. During the observations from 2014 February to 2014 April, the spot distortion phase jumped between phases 0.25 and 0.75 twice, a typical indication of flip-flop activity. We applied the Wilson–Devinney method to analyze the three light curves. The results indicate that HH UMa is a partially eclipsing contact system of A subtype with an obviously asymmetric light curve. The observed light curves can be modeled by assuming that there are two dark spots on the massive primary component that are almost persistently located around phases 0.25 and 0.75, but can interchange their intensities. We further suggest that a plausible scenario for explaining the properties of those dark spots is strong surface magnetic activity with a sudden reversal of the more active longitude. We therefore conclude that HH UMa is very likely a W UMa-type system displaying flip-flop activity.

    We present new [SII] images of the HH 30 jet and counterjet observed in 2006, 2007, and 2010 that allowed us to measure with improved accuracy the positions and proper motions of the jet and counterjet knots. Our results show that the motion of the knots is essentially ballistic, with the exception of the farthest knots, which trace the large scale C-shape bending of the jet. The observed bending of the jet can be produced by a relative motion of the HH 30 star with respect to its surrounding environment, caused either by a possible proper motion of the HH 30 star, or by the entrainment of environment gas by the red lobe of the nearby L1551-IRS 5 outflow. Alternatively, the bending can be produced by the stellar wind from a nearby CTTS, identified in the 2MASS catalog. The proper motion velocities of the knots of the counterjet show more variations than those of the jet. In particular, we identify two knots of the counterjet that have the same kinematic age but whose velocities differ by almost a factor of tw...

    In this document we study the effect of anomalous Higgs boson couplings on non-resonant pair production of Higgs bosons ($HH$) at the LHC. We explore the space of the five parameters $\\kappa_{\\lambda}$, $\\kappa_{t}$, $c_2$, $c_g$, and $c_{2g}$ in terms of the corresponding kinematics of the final state, and describe a partition of the space into a limited number of regions featuring similar phenomenology in the kinematics of $HH$ final state. We call clusters the sets of points belonging to the same region; to each cluster corresponds a representative point which we call a benchmark. We discuss a possible technique to estimate the sensitivity of an experimental search to the kinematical differences between the phenomenology of the benchmark points and the rest of the parameter space contained in the corresponding cluster. We also provide an analytical parametrization of the cross-section modifications that the variation of anomalous couplings produces with respect to standard model $HH$ production along with ...

    Full Text Available During the past few years, there has been growing interests in reducing cost of products and services among developing countries. Privatization is believed to be one of the most important techniques to increase relative efficiencies of publically held organizations. In this paper, we study important barriers on privatization of television (TV media industry in Iran. The proposed study of this paper designs and distributes a questionnaire using a sample of 234 out of 600 graduate students who were enrolled in media communication studies and examined six hypotheses based on one-side t-student. The survey considers different factors influencing privatization of TV media industry. The results of the investigation indicate that the cost of TV production, short and long-term investment security, people's interest on investing on TV media industry, building appropriate culture, cultural obstacles and economic barriers influence media privatization, significantly.

    The H-Fe interaction near a bcc Fe vacancy is analysed using a semi-empirical theoretical method. Calculations were performed using a Fe{sub 86} cluster with a vacancy. Hydrogen atoms are positioned in their local energy minima configurations. Changes in the electronic structure of Fe atoms near a vacancy were analysed for the system without H, with one H and with two H atoms. Fe atoms surrounding the vacancy weaken their bond when hydrogen is present. This is due to the formation of H-Fe bonds. Hydrogen influences only its nearest-neighbour Fe atoms. The H-H interaction was also analysed. For H-H distance of 0.82 Angstrom an H-H association is formed, while H-Fe interaction and Fe-Fe weakening is markedly reduced, when compared with other H-H interactions. (author)

  1. Detailed optical study of HH 32 and the highly collimated outflow from the T Tauri star AS 353A

    1986-06-01

    The T Tauri star AS 353A and its highly collimated bipolar outflow have been studied using medium- and high-resolution spectroscopy and deep emission-line CCD imagery. We report the discovery of a linear emission jet in the redshifted part of the flow, and present spectra of the HH objects (HH 32A--D) that confirm the bipolarity of the flow. Despite widely varying line profiles, all four HH objects have similar extremely broad emission linewidths and maximum radial velocities (approx.400 km/s) as well as nearly constant number density as a function of radial velocity. Three of the four objects (HH 32D is the possible exception) possess prominent double-peaked emission-line profiles, and in HH 32A and HH 32C the high-velocity component is situated closer to the star than the low-velocity component. The line profile of (O III) lambda5007 differs markedly from the profiles of lower-excitation lines for HH 32A. These characteristics are examined in the light of two physical models: HH objects as strongly radiating shocks in outflowing jets or as single bow shocks around dense clumps in the outflow. Both are successful in explaining the majority of characteristics observed, but both models encounter some difficulties. The stellar wind has been studied through examination of the star's emission and absorption lines, and we find that the wind is already accelerated to 300 km/s close to the star, and reaches a terminal velocity in excess of 350 km/s. The blueshifted component of the H..cap alpha.. profile of AS 353A is highly variable, and the profiles of different lines have quite dissimilar characteristics. The P Cygni line profiles are discussed briefly in terms of two wind models. There is evidence that the flow collimation occurs at distances greater than two stellar radii.

  10. Private Health Insurance Exchanges

    Buttorff, Christine; Nowak, Sarah; Syme, James; Eibner, Christine

    2017-01-01

    Abstract Private health insurance exchanges offer employer health insurance, combining online shopping, increased plan choice, benefit administration, and cost-containment strategies. This article examines how private exchanges function, how they may affect employers and employees, and the possible implications for the Affordable Care Act's (ACA's) Small Business Health Options Program (SHOP) Marketplaces. The authors found that private exchanges could encourage employees to select less-generous plans. This could expose employees to higher out-of-pocket costs, but premium contributions would drop substantially, so net spending would decrease. On the other hand, employee spending may increase if, in moving to private exchanges, employers decrease their health insurance contributions. Most employers can avoid the ACA's “Cadillac tax” by reducing the generosity of the plans they offer, regardless of whether they move to a private exchange. There is not yet enough evidence to determine whether the private exchanges will become prominent in the insurance market and how they will affect employers and their employees. PMID:28845340

    Microphysiological systems (organs-on-chips, tissue chips) are devices designed to recapitulate human physiology that could be used to better understand drug responses not easily addressed using other in vivo systems or in vitro animal models. Although still in development, initial results seem promising as tissue chips exhibit in vivo systems-like functional responses. The National Center for Advancing Translation Science (NCATS) identifies this technology as a potential tool that could improve the process of getting safer, more effective treatments to patients, and has led to the Tissue Chip Program, which aims to develop, integrate and validate major organ systems for testing. In addition to organ chip development, NCATS emphasizes disseminating the technology to researchers. Commercialization has become an important issue, reflecting the difficulty of translation from discovery to adoption and wide availability. Therefore, NCATS issued a Request for Information (RFI) targeted to existing partnerships for commercializing tissue chips. The goal was to identify successes, failures and the best practices that could provide useful guidance for future partnerships aiming to make tissue chip technology widely available.

  17. Privatization Process in Kosovo

    2014-06-01

    Full Text Available Privatization is considered an initial step toward market economy, restructuring financial and economic sector that enables competition in the economy. Privatization is the most painful process in economy where beside legal establishment and political will, it includes also the aspect of fairness and honesty. Analysis of this process is based on the models and comparisons between Kosovo and countries of central and Eastern Europe, in order to give a clearer picture on the overall process of privatization in Kosovo Methodology that is used to analyze this issue is based on empirical results and also qualitative interpretation of the models and also on studying particular asset privatization process. A widely discussed case of privatization in Kosovo is that of Post and Telecom of Kosovo (PTK. Since each company has its own value, I have focused my appraising analysis on the financial statements with a special observation on Cash Flow from Operation, as the most significant indicator on showing how company is using her physical and human recourses to generate money. I have based my research on using methodology of discounted cash flow from operation analysis, even though the company valuation was done using net cash flow from operation analysis. Cash Flow valuation then was discounted by the T-bonds interest rate. This paper tries to bring a conclusion that privatization process in Kosovo have not brought the results excepted, firstly by setting an inappropriate price of assets and lastly by restructuring overall privatization sector and the overall industry. Kosovo, consequently, lost a big opportunity to create a competitive environment of financial industry: starting from the banking industry followed the pension trust which remained at their initial steps of development

    We present 6 and 20 cm JVLA/VLA observations of the northern head of the HH 80/81/80N jet, one of the largest collimated jet systems known so far, aimed to look for knots further away than HH 80N, the northern head of the jet. Aligned with the jet and 10 arcmin northeast of HH 80N, we found a radio source not reported before, with a negative spectral index similar to that HH 80, HH 81 and HH 80N. The fit of a precessing jet model to the knots of the HH 80/81/80N jet, including the new source, shows that the position of this source is close to the jet path resulting from the modeling. If the new source belongs to the HH 80/81/80N jet, its derived size and dynamical age are 18.4 pc and >9000 yr, respectively. If the jet is symmetric, its southern lobe would expand beyond the cloud edge resulting in an asymmetric appearance of the jet. Based on the updated dynamical age, we speculate on the possibility that the HH 80/81/80N jet triggered the star formation observed in a dense core found ahead of HH 80N, which sh...

  1. Searches for diboson resonances with ATLAS (VV, VH and HH, excl. diphoton resonance)

    Gregersen, Kristian; The ATLAS collaboration

    2016-01-01

    An overview of ATLAS diboson resonance searches with LHC Run 2 data at 13 TeV are summarized in this talk. Resonant production of two bosons is a clear hint for physics beyond the Standard Model, potentially related to the nature of the electroweak symmetry breaking mechanism in the SM. Searches for diboson resonances have been performed in VV, VH and HH diboson channels with final states with different numbers of leptons and primarily in boosted topologies where the hadronically decaying bosons can be reconstructed as one large-radius jet.

    One of the main challenges when designing final focus systems of particle accelerators is maximising the beam stay clear in the strong quadrupole magnets of the inner triplet. Moreover it is desirable to keep the quadrupoles in the triplet as short as possible for space and costs reasons but also to reduce chromaticity and simplify corrections schemes. An algorithm that explores the triplet parameter space to optimise both these aspects was written. It uses thin lenses as a first approximation and MADX for more precise calculations. In cooperation with radiation studies, this algorithm was then applied to design an alternative triplet for the final focus of the Future Circular Collider (FCC-hh).

    This document summarises ATLAS searches for resonances decaying to diboson final states, VV , VH and HH, where V is either a W or a Z boson and H is the Standard Model Higgs boson. The results obtained are based on the full 2015 dataset corresponding to an integrated luminosity of 3.2 fb −1 . No discrepancies with respect to the Standard Model expectations are observed and thus 95% confidence level exclusion limits are set on the production cross section times branching ratios in a number of benchmark scenarios, including Heavy Vector Triplet, Randall-Sundrum Graviton and Extended Higgs sector models.

  4. Radiation Load Optimization in the Final Focus System of FCC-hh

    Martin, Roman; Cerutti, Francesco; Tomás, Rogelio

    2016-01-01

    With a center-of-mass energy of up to 100 TeV, FCC-hh will produce highly energetic collision debris at the Interaction Point (IP). Protecting the final focus quadrupoles from this radiation is challenging, since the required amount of shielding placed inside the magnets will reduce the free aperture, thereby limiting the β^{*} reach and luminosity. Hence, radiation mitigation strategies that make best use of the available aperture are required. In this paper, we study the possibility to split the first quadrupole Q1 into two quadrupoles with individual apertures, in order to distribute the radiation load more evenly and reduce the peak dose.

    2010-01-01

    Full Text Available This paper highlights systemic contextual differences and the unique IT Governance issues that might arise in public and private sector organizations. Public sector organizations constitute a significant component of economic activity in most countries. Like their private sector counterparts, many public sector agencies are struggling to cope with reduced or inadequate IT budgets and are continuously looking for ways to extract maximum value from IT resources. While both sectors face similar managerial-level IT issues and challenges, we argue that there are systemic differences between private and public sector organizations suggesting that a one size fits all approach to IT Governance may not apply.

    2011-01-01

    Differential privacy has recently emerged as the de facto standard for private data release. This makes it possible to provide strong theoretical guarantees on the privacy and utility of released data. While it is well-known how to release data based on counts and simple functions under this guarantee, it remains to provide general purpose techniques to release different kinds of data. In this paper, we focus on spatial data such as locations and more generally any data that can be indexed by a tree structure. Directly applying existing differential privacy methods to this type of data simply generates noise. Instead, we introduce a new class of "private spatial decompositions": these adapt standard spatial indexing methods such as quadtrees and kd-trees to provide a private description of the data distribution. Equipping such structures with differential privacy requires several steps to ensure that they provide meaningful privacy guarantees. Various primitives, such as choosing splitting points and describi...

    Full Text Available One of the most important issues in privatization is to measure the impact of such decisions on improving efficiency of governmental organizations. Privatization, in the past, has had both positive and negative consequences in different countries. Therefore, it is necessary to measure the impact of privatization in Iran to see the outcome of such decision. In this paper, we present an empirical study to measure the financial performance of the privatized firms three years before and three years after privatization happed using pairwise t-student. We use five financial figures of asset turnover, working capital turnover, return on assets, return on equity and earnings per share. The results indicate that there was no meaningful relationship between these financial figures before and after privatization occurred.

    Protostellar jets appear at all stages of star formation when the accretion process is still at work. Jets travel at velocities of hundreds of km s{sup –1}, creating strong shocks when interacting with the interstellar medium. Several cases of jets have been detected in X-rays, typically showing soft emission. For the first time, we report evidence of hard X-ray emission possibly related to non-thermal processes not explained by previous models of the post-shock emission predicted in the jet/ambient interaction scenario. HH 80 is located at the south head of the jet associated with the massive protostar IRAS 18162-2048. It shows soft and hard X-ray emission in regions that are spatially separated, with the soft X-ray emission region situated behind the region of hard X-ray emission. We propose a scenario for HH 80 where soft X-ray emission is associated with thermal processes from the interaction of the jet with denser ambient matter and hard X-ray emission is produced by synchrotron radiation at the front shock.

    Aims: Using the unprecedented combination of high resolution and sensitivity offered by ALMA, we aim to investigate whether and how hot corinos, circumstellar disks, and ejected gas are related in young solar-mass protostars. Methods: We observed CH$_3$CHO and deuterated water (HDO) high-excitation ($E_{\\rm u}$ up to 335 K) lines towards the Sun-like protostar HH212--MM1. Results: For the first time, we have obtained images of CH$_3$CHO and HDO emission in the inner $\\simeq$ 100 AU of HH212. The multifrequency line analysis allows us to contrain the density ($\\geq$ 10$^{7}$ cm$^{-3}$), temperature ($\\simeq$ 100 K), and CH$_3$CHO abundance ($\\simeq$ 0.2--2 $\\times$ 10$^{-9}$) of the emitting region. The HDO profile is asymmetric at low velocities ($\\leq$ 2 km s$^{-1}$ from $V_{\\rm sys}$). If the HDO line is optically thick, this points to an extremely small ($\\sim$ 20--40 AU) and dense ($\\ge$ 10$^{9}$ cm$^{-3}$) emitting region. Conclusions: We report the first detection of a hot corino in Orion. The HDO asymm...

    Bonito, R; Miceli, M; Peres, G; Micela, G; Favata, F

    2011-01-01

    X-ray emission from about ten protostellar jets has been discovered and it appears as a feature common to the most energetic jets. Although X-ray emission seems to originate from shocks internal to jets, the mechanism forming these shocks remains controversial. One of the best studied X-ray jet is HH 154 that has been observed by Chandra over a time base of about 10 years. We analyze the Chandra observations of HH 154 by investigating the evolution of its X-ray source. We show that the X-ray emission consists of a bright stationary component and a faint elongated component. We interpret the observations by developing a hydrodynamic model describing a protostellar jet originating from a nozzle and compare the X-ray emission synthesized from the model with the X-ray observations. The model takes into account the thermal conduction and radiative losses and shows that the jet/nozzle leads to the formation of a diamond shock at the nozzle exit. The shock is stationary over the period covered by our simulations and...

  15. Optimizing laboratory animal stress paradigms: The H-H* experimental design.

    McCarty, Richard

    2017-01-01

    Major advances in behavioral neuroscience have been facilitated by the development of consistent and highly reproducible experimental paradigms that have been widely adopted. In contrast, many different experimental approaches have been employed to expose laboratory mice and rats to acute versus chronic intermittent stress. An argument is advanced in this review that more consistent approaches to the design of chronic intermittent stress experiments would provide greater reproducibility of results across laboratories and greater reliability relating to various neural, endocrine, immune, genetic, and behavioral adaptations. As an example, the H-H* experimental design incorporates control, homotypic (H), and heterotypic (H*) groups and allows for comparisons across groups, where each animal is exposed to the same stressor, but that stressor has vastly different biological and behavioral effects depending upon each animal's prior stress history. Implementation of the H-H* experimental paradigm makes possible a delineation of transcriptional changes and neural, endocrine, and immune pathways that are activated in precisely defined stressor contexts.

  16. GT1_abenz_1: Completing the OH ladder for HH 46

    Science.gov (United States)

    Benz, A.

    2010-03-01

    First results from PACS observations towards the low-mass protostar HH 46 show surprisingly bright OH lines. The hydroxyl radical OH plays important roles in the water and oxygen chemistry of star-forming regions and their cooling. Furthermore, the hydroxyl-to-water line ratios are interesting tracers for ionizing radiation. We propose a nearly complete observation of the OH ladder in low-mass star formation for the first time. Four OH transitions in the class I object HH 46 were detected by PACS. We propose complementary observations towards the source in PACS line spectroscopy mode at 53, 56, 65, 71, 96, 115 and 135 micron. We gain insight in the origin and formation of OH from the PACS spatial information. The completeness of the OH ladder allows a reliable determination of the OH abundance and thus constrains water chemistry and cooling contribution more precisely. In addition, we propose HIFI observations of the OH transition at 163.4 micron to resolve the three hyperfine components for the first time. This will allow to determine optical depths of OH and test the hypothesis of asymmetries between the two closely spaced triplets, as the second triplet will be observed within the HIFI priority science program.

    In this work we derive the full 3-D kinematics of the near-infrared outflow HH 223, located in the dark cloud Lynds 723 (L723), where a well-defined quadrupolar CO outflow is found. HH 223 appears projected onto the two lobes of the east-west CO outflow. The radio continuum source VLA 2, towards the centre of the CO outflow, harbours a multiple system of low-mass young stellar objects. One of the components has been proposed to be the exciting source of the east-west CO outflow. From the analisys of the kinematics, we get further evidence on the relationship between the near-infrared and CO outflows and on the location of their exciting source. The proper motions were derived using multi-epoch, narrow-band H$_2$ (2.122 $\\mu$m line) images. Radial velocities were derived from the 2.122 $\\mu$m line of the spectra.

    2016-01-01

    We present an analysis of four epochs of H$\\alpha$ and [S II] $\\lambda\\lambda$ 6716/6731 HST images of HH 1. For determining proper motions we explore a new method based on analysis of spatially degraded images obtained convolving the images with wavelet functions of chosen widths. With this procedure we are able to generate maps of proper motion velocities along and across the outflow axis, as well as (angularly integrated) proper motion velocity distributions. From the four available epochs, we find the time evolution of the velocities, intensities and spatial distribution of the line emission. We find that over the last two decades HH 1 shows a clear acceleration. Also, the H$\\alpha$ and [S II] intensities have first dropped, and then recovered in the more recent (2014) images. Finally, we show a comparison between the two available HST epochs of [O III] $\\lambda$ 5007 (1994 and 2014), in which we see a clear drop in the value of the [O III]/H$\\alpha$ ratio.

  20. 20 years of cosmic muons research performed in IFIN-HH

    Energy Technology Data Exchange (ETDEWEB)

    Mitrica, Bogdan [Horia Hulubei National Institute of Physics and Nuclear Engineering - IFIN HH, Bucharest, P.O.B.MG-6 (Romania)

    2012-11-20

    During the last two decades a modern direction in particle physics research has been developed in IFIN-HH Bucharest, Romania. The history started with the WILLI detector built in IFIN-HH Bucharest in collaboration with KIT Karlsruhe (formerly Forschungszentrum Karlsruhe). The detector was designed for measurements of the low energy muon charge ratio (< 1GeV) based on a delayed coincidence method, measuring the decay time of the muons stopped in the detector: the positive muons decay freely, but the negative muons are captured in the atom thus creating muonic atoms and decay depending on the nature of the host atom. In a first configuration, the WILLI detector was placed in a fixed position for measuring vertical muons. Further WILLI has been transformed in a rotatable device which allows directional measurements of muon charge ratio and muon flux. The results exhibit a pronounced azimuthal asymmetry (East-West effect) due to the different in fluence of the geomagnetic field on the trajectories of positive and negative muons in air. In parallel, flux measurement, taking into account muon events with nergies > 0.4GeV, show a diurnal modulation of the muon flux. The analysis of the muon events for energies < 0.6GeV reveals an aperiodic variation of the muon flux. A new detection system performing coincidence measurements between the WILLI calorimeter and a small array of 12 scintillators plates has been installed in IFIN-HH starting from the autumn of 2010. The aim of the system is to investigate muon charge ratio from individual EAS by using the mini-array as trigger for the WILLI calorimeter. Such experimental studies could provide detailed information on hadronic interaction models and primary cosmic ray composition at energies around 10{sup 15}eV. Simulation studies and preliminary experimental tests, regarding the performances of the mini-array, have been performed using H and Fe primaries, with energies in a range 10{sup 13}eV - 10{sup 15}eV. The results show

    Full Text Available This study examines the problems of reduction of individual’s efficiency in his/her respective working places because of road traffic noise pollution in Agartala due to rapidly growing vehicular traffic. This paper deals with monitoring and modeling of the disturbances caused due to vehicular road traffic interrupted by traffic flow conditions on personal work performance. Total of two hundred seventy individuals from different road side Government Offices, Private Organizations and Commercial Business Centres on both sides of busy roads of the city were interviewed for attitudinal responses. Traffic volume count and noise indices data were collected simultaneously at six selected sites of the city. A relationship was developed between different traffic noise parameters and its harmful impact on work competency of individuals using MATLAB. Regression equations developed to predict the percentage of high annoyance among the individuals are fit based on noise parameters and parameters related to traffic movements. In addition, statistical analysis was also carried out between measured and predictive values of the percentage of highly annoyed group of individuals. The present model will draw the attention of the State Government and will help the policy maker to take the necessary steps to reduce this problem.

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Hedgehog (Hh signaling regulates multiple aspects of metazoan development and tissue homeostasis, and is constitutively active in numerous cancers. We identified Ubr3, an E3 ubiquitin ligase, as a novel, positive regulator of Hh signaling in Drosophila and vertebrates. Hh signaling regulates the Ubr3-mediated poly-ubiquitination and degradation of Cos2, a central component of Hh signaling. In developing Drosophila eye discs, loss of ubr3 leads to a delayed differentiation of photoreceptors and a reduction in Hh signaling. In zebrafish, loss of Ubr3 causes a decrease in Shh signaling in the developing eyes, somites, and sensory neurons. However, not all tissues that require Hh signaling are affected in zebrafish. Mouse UBR3 poly-ubiquitinates Kif7, the mammalian homologue of Cos2. Finally, loss of UBR3 up-regulates Kif7 protein levels and decreases Hh signaling in cultured cells. In summary, our work identifies Ubr3 as a novel, evolutionarily conserved modulator of Hh signaling that boosts Hh in some tissues.

The anti-CD37 monoclonal antibody HH1 was conjugated to the bifunctional chelator p-SCN-Bn-DOTA and labelled with the beta-particle emitting radionuclide 177Lu creating the radio-immunoconjugate (RIC) 177Lu-DOTA-HH1 (177Lu-HH1, trade name Betalutin). The present toxicity study was performed prior to initiation of clinical studieswith 177Lu-HH1. Methodology/Principal Findings Nude mice with or without tumor xenografts were treated with 50 to 1000 MBq/kg 177Lu- HH1 and followed for clinical signs of toxicity up to ten months. Acute, life threatening bone marrow toxicity was observed in animals receiving 800 and 1000 MBq/kg 177Lu-HH1. Significant changes in serum concentrations of liver enzymes were evident for treatment with 1000 MBq/kg 177Lu-HH1. Lymphoid depletion, liver necrosis and atrophy, and interstitial cell hyperplasia of the ovaries were also observed for mice in this dose group. Conclusions/Significance 177Lu-DOTA-HH1 was well tolerated at dosages about 10 times above those considered relevant for radioimmunotherapy in patients with B-cell derived malignancies.The toxicity profile was as expected for RICs. Our experimental results have paved the way for clinical evaluation of 177Lu-HH1 in NHL patients. PMID:25068508

    Full Text Available Calculamos modelos axisimétricos, con una variación sinusoidal (de un modo y un perfil de sección recta inicial de velocidad. Encontramos que para cocientes de velocidad borde a centro decrecientes, uno obtiene superficies de trabajo con choques de proa con alas progresivamente más extendidas. Estas alas producen emisión de [S II] que parcialmente llena las regiones entre los nudos en los mapas de emisión predichos. Luego calculamos modelos de 3 modos (con parámetros apropiados para el chorro HH 34, y comparamos los mapas de emisión predichos con imágenes del archivo del HST de HH 34. Encontramos que un modelo con cociente de velocidades borde a centro moderado produce estructuras de nudos con morfologías y variabilidades temporales muy parecidas a las observadas en HH 34.

    We present a new Spitzer IRAC images of the HH 34 outflow. These are the first images that detect both the knots along the southern jet and the northern counterjet (the counterjet knots were only detected previously in a long slit spectrum). This result removes the problem of the apparent coexistence of a large scale symmetry (at distances of up to approx.1 pc) and a complete lack of symmetry close to the source (at distances of approx. 1.e+17 cm) for this outflow. We present a quantitative evaluation of the newly found symmetry between the HH 34 jet and counterjet, and show that the observed degree of symmetry implies that the jet production region has a characteristic size <2.8 AU. This is the strongest constraint yet derived for the size of the region in which HH jets are produced.

    In the giant panda, adaptation to a high-fiber environment is a first step for the adequate functioning of intestinal bacteria, as the high cellulose content of the gut due to the panda's vegetarian appetite results in a harsh environment. As an excellent producer of several enzymes and vitamins, Bacillus subtilis imparts various advantages to animals. In our previous study, we determined that several strains of B. subtilis isolated from pandas exhibited good cellulose decomposition ability, and we hypothesized that this bacterial species can survive in and adapt well to a high-fiber environment. To evaluate this hypothesis, we employed RNA-Seq technology to analyze the differentially expressed genes of the selected strain B. subtilis HH2, which demonstrates significant cellulose hydrolysis of different carbon sources (cellulose and glucose). In addition, we used bioinformatics software and resources to analyze the functions and pathways of differentially expressed genes. Interestingly, comparison of the cellulose and glucose groups revealed that the up-regulated genes were involved in amino acid and lipid metabolism or transmembrane transport, both of which are involved in cellulose utilization. Conversely, the down-regulated genes were involved in non-essential functions for bacterial life, such as toxin and bacteriocin secretion, possibly to conserve energy for environmental adaptation. The results indicate that B. subtilis HH2 triggered a series of adaptive mechanisms at the transcriptional level, which suggests that this bacterium could act as a probiotic for pandas fed a high-fiber diet, despite the fact that cellulose is not a very suitable carbon source for this bacterial species. In this study, we present a model to understand the dynamic organization of and interactions between various functional and regulatory networks for unicellular organisms in a high-fiber environment.

    The issue of private language entered in the scope of philosophy by Wittgenstein. In his important book, Philosophical Investigations (1953), he argues that the private language is impossible. According to him, the pervious systems of philosophy like Rationalism, Empiricism, Idealism and even Logical Atomism explain the raise of knowledge so that it entails private language. Private language, Wittgenstein defines, is a language whose individual words refer to what can only be known to the spe...

    We present new [S II] images of the Herbig-Haro (HH) 30 jet and counterjet observed in 2006, 2007, and 2010 that, combined with previous data, allowed us to measure with improved accuracy the positions and proper motions of the jet and counterjet knots. Our results show that the motion of the knots is essentially ballistic, with the exception of the farthest knots, which trace the large-scale 'C'-shape bending of the jet. The observed bending of the jet can be produced by a relative motion of the HH 30 star with respect to its surrounding environment, caused either by a possible proper motion of the HH 30 star, or by the entrainment of environment gas by the red lobe of the nearby L1551-IRS5 outflow. Alternatively, the bending can be produced by the stellar wind from a nearby classical T Tauri star, identified in the Two Micron All Sky Survey catalog as J04314418+181047. The proper motion velocities of the knots of the counterjet show more variations than those of the jet. In particular, we identify two knots of the counterjet that have the same kinematic age but whose velocities differ by almost a factor of two. Thus, it appears from our observations that counterjet knots launched simultaneously can be ejected with very different velocities. We confirm that the observed wiggling of the jet and counterjet arises from the orbital motion of the jet source in a binary system. Precession, if present at all, is of secondary importance in shaping the jet. We derive an orbital period of {tau}{sub o} = 114 {+-} 2 yr and a mass function of m{mu}{sup 3}{sub c} = 0.014 {+-} 0.006 M{sub Sun }. For a mass of the system of m = 0.45 {+-} 0.04 M{sub Sun} (the value inferred from observations of the CO kinematics of the disk), we obtain a mass of m{sub j} = 0.31 {+-} 0.04 M{sub Sun} for the jet source, a mass of m{sub c} = 0.14 {+-} 0.03 M{sub Sun} for the companion, and a binary separation of a = 18.0 {+-} 0.6 AU. This binary separation coincides with the value required

    We introduce Higgs democracy in the Yukawa sector by constructing a model with a private Higgs field for each fermion, and an O(1) Yukawa coupling between them, thus addressing the large hierarchy among fermion masses. The Standard Model phenomenology is recovered, in particular no tree level FCNCs are present. We discuss some phenomenological implications which include new Higgses at the TeV scale and a candidate for dark matter.

    The Future Circular Collider (FCC) design study aims to develop the designs of possible circular colliders in the post LHC era. In particular the FCC-hh will aim to produce proton-proton collisions at a center of mass energy of 100 TeV. Given the large beta functions and integrated length of the quadrupoles of the final focus triplet the effect of systematic and random non linear errors in the magnets are expected to have a severe impact on the stability of the beam. Following the experience on the HL-LHC this work explores the implementation of non-linear correctors to minimize the resonance driving terms arising from the errors of the triplet. Dynamic aperture studies are then performed to study the impact of this correction.

    A 100 TeV pp collider is under consideration, by the high-energy physics community, as an important step for the future development of our field, following the completion of the LHC and High-luminosity LHC physics programmes. In particular, CERN is considering 100 TeV pp collisions as the key target of a Future Circular Collider facility, built around a 100 km tunnel and designed to deliver pp, e+e- and ep collisions, in addition to a programme with heavy ion beams and with the injector complex. CERN is coordinating an international study tasked with the completion, by the end of 2018, of a Conceptual Design Report (CDR) for this facility. This document presents the first results of the assessment of the physics potential of the hadronic part of this research programme (FCC-hh).

  17. Proton cross-talk and losses in the dispersion suppressor regions at the FCC-hh

    2017-01-01

    Protons that collide at the interaction points of the FCC-hh may contribute to the background in the subsequent detector. Due to the high luminosity of the proton beams this may be of concern. Using DPMJET-III to model 50 TeV proton-proton collisions, tracking studies have been performed with PTC and MERLIN in order to gauge the elastic and inelastic proton cross-talk. High arc losses, particularly in the dispersion suppressor regions, have been revealed. These losses originate mainly from particles with a momentum deviation, either from interaction with a primary collimator in the betatron cleaning insertion, or from the proton-proton collisions. This issue can be mitigated by introducing additional collimators in the dispersion suppressor region. The specific design, lattice integration, and the effect of these collimators on cross-talk is assessed.

    2017-01-01

    The discovery of a Higgs boson at the Large Hadron Collider motivates searches for physics beyond the Standard Model in channels involving coupling to the Higgs boson. A search for massive resonances decaying into couples of bosons is described. The considered final states are: $HH$, $VH$, $VV$, $V\\gamma$ and $\\gamma\\gamma$ with $V$ indicating either the $W$ or the $Z$ boson. Final states with different number of leptons or photons and where, in many cases, at least one Higgs decays into a b-quark pair are studied using different jet reconstruction techniques which allow to optimize the signal acceptance for low or Higgs boson transverse momentum. The most recent diboson resonance searches using LHC Run 2 data are described.

    Full Text Available This thesis investigates the linear free vibrations of functionally graded Carbon Nano-tube reinforced Composite (FG-CNTRC beams using Slender (Euler-Bernoulli’s beam theory. The material properties of FG-CNTRCs are assumed to be graded in the thickness direction and estimated through the rule of mixture. The Ritz method is employed to derive the governing Eigen value equation which is then solved by a direct iterative method to obtain the linear frequencies of FG-CNTRC beams with H-H Supports. A detailed parametric study is conducted to study the influences of Nanotube volume fraction, vibration amplitude, and slenderness ratio on the linear free vibration characteristics of FG-CNTRC beams.

    We report on a detailed study of the physics of molecular shocks using Gemini NIFS (Near-Infrared Field Spectrometer) K-band spectra of a 3.'2 x 2.'9 region near the tip of the HH7 bow shock. The IFU data have an angular resolution of 0.3", much higher resolution then in any previous study of a molecular shock, and a velocity resolution of 60 km/s. We have detected 20 H2 emission lines with upper state energies as high as 28,000 K, and 6 additional unidentified lines which share the same bow shock morphology as the H2. We use excitation temperatures derived from line pairs measured in 0.15' x 0.15' bins to attempt to constrain the shock type and distinguish between low velocity jump shocks, continuous shocks, and dissociative shocks in which the H2 line emission arises from newly reformed H2.

    Our ALMA multi-cycle multi-band observations of HH46/47 outflow show co-existence of entrainment by both wide-angle wind and jet bow-shock and this outflow is at a moment that the former has just become dominant. The estimated outflow mass and strength suggest that it has already strongly affected the core-to-star efficiency to 1/3 at this early stage. The zoom-in observation also reveals multiple wide outflowing shells with positions and shapes smoothly changing over a wide range of velocity, which may be an evidence of episodic eruption not only in jet but also in the wide-angle wind.

    Many of the new physics models predicts a light Higgs boson similar to the Higgs boson of the Standard Model (SM) and also extra scalar bosons. Beyond the search channels for a SM Higgs boson, the future collider experiments will explore additional channels that are specific to extended Higgs sectors. We study the charged Higgs boson production within the framework of two Higgs doublet models (THDM) in the proton-proton collisions at the FCC-hh collider. With an integrated luminosity of 500 fb$^{-1}$ at very high energy frontier, we obtain a significant coverage of the parameter space and distinguish the charged Higgs-top-bottom interaction within the THDM or other new physics models with charged Higgs boson mass up to 1 TeV.

    We report on initial results of our Spitzer Cycle 2 program to observe the young massive star R Mon and its associated HH 39 Herbig-Haro object in the mid-infrared. Our program used all instruments on-board Spitzer to obtain deep images with IRAC of the HH 39 complex and of R Mon and its surroundings, a deep image of HH 39 at 24 and 70 $\\mu$m with MIPS, and mid-infrared spectra with the SH, LH, and LL modules of IRS. The aim of this program is to study the physical links in a young massive star between accretion disk, outflows and jets, and sh ocks in the associated HH object. Our preliminary analysis reveals that several knots of HH 39 are clearly detected in most IRAC bands. In IRAC4 (8 $\\mu$m), diffuse emission, probably from PAHs, appears as foreground emission covering the HH 39 emission. The HH 39 knots are detected at 24 microns, despite the fact that dust continuum emission covers the knots and shows the same structure as observed with IRAC4. The IRS spectra of HH 39 show weak evidence of [Ne II] 12.8...

  8. Markets & Myths: Autonomy in Public & Private Schools

    Full Text Available

    School choice is the most controversial education policy issue of the 1990s. John Chubb and Terry Moe's Politics, Markets and America's Schools stimulated this investigation. They concluded that teacher and administrator autonomy was the most important influence on student achievement. They assumed that the organization of private schools offered greater autonomy resulting in higher student achievement and that the bureaucracy of public schools stifles autonomy limiting student achievement. The research undertaken here elaborates, elucidates, and fills in the framework of teacher and principal autonomy in public and private secondary schools. Interviews of more than thirty teachers and administrators in six high schools, observations, field notes, and analysis of documents collected in the field form the empirical base of this work. The sites included three private, independent, nondenominational secondary schools which are college preparatory and three public secondary schools noted for high graduation rates and offering numerous advanced placement courses.

    The feelings expressed by both public and private school participants in this study testify to equally high degrees of autonomy. Issues that emerged from data analysis in this study which mitigate and shape autonomy include the following: conflicting and contradictory demands, shared beliefs, layers of protection, a system of laws, funding constraints and matters of size of the institution. These issues challenge oversimplified assertions that differences of any importance exist between the autonomy experienced by professionals in public and private high schools. This study reveals the complexity of the concept of autonomy and challenges the myth that teachers and principals in private schools enjoy autonomy and freedom from democratic bureaucracy that their public school counterparts do not.

    The HH54 shock is a Herbig-Haro object, located in the nearby Chamaeleon II cloud. Observed CO line profiles are due to a complex distribution in density, temperature, velocity, and geometry. Resolving the HH54 shock wave in the far-infrared cooling lines of CO constrain the kinematics, morphology, and physical conditions of the shocked region. We used the PACS and SPIRE instruments on board the Herschel space observatory to map the full FIR spectrum in a region covering the HH54 shock wave. Complementary Herschel-HIFI, APEX, and Spitzer data are used in the analysis as well. The observed features in the line profiles are reproduced using a 3D radiative transfer model of a bow-shock, constructed with the Line Modeling Engine code (LIME). The FIR emission is confined to the HH54 region and a coherent displacement of the location of the emission maximum of CO with increasing J is observed. The peak positions of the high-J CO lines are shifted upstream from the lower J CO lines and coincide with the position of ...

  10. Modelling the Emission And/or Absorption Features in the High Resolution Spectra of the Southern Binary System: HH Car

    2016-07-01

    High-resolution spectra (R=48000) of the southern close binary system, HH Car, has been analyzed with modern analysis techniques. Precise absolute parameters were derived from the simultaneous solution of the radial velocity, produced in this study and the light curves, published. According to the results of these analyses, the primary component is an O9 type main sequence star while the secondary component is a giant/subgiant star with a spectral type of B0. Hα emissions can be seen explicitly in the spectra of HH Car. These features were modelled using the absolute parameters of the components. Since components of HH Car are massive early-type stars, mass loss through stellar winds can be expected. This study revealed that the components of HH Car have stellar winds and the secondary component loses mass to the primary. Stellar winds and the gas stream between the components were modelled as a hot shell around the system. It is determined that the interaction between the winds and the gas stream leads to formation of a high temperature impact region.

    Dense atomic jets from young stars copiously emit in [FeII] IR lines, which can, therefore, be used to trace the immediate environments of embedded protostars. We want to investigate the morphology of the bright [FeII] 1.64um line in the jet of the source HH34 IRS and compare it with the most commonly used optical tracer [SII]. We analyse a 1.64um narrow-band filter image obtained with the Large Binocular Telescope (LBT) LUCI instrument, which covers the HH34 jet and counterjet. A Point Spread Function (PSF) deconvolution algorithm was applied to enhance spatial resolution and make the IR image directly comparable to a [SII] HST image of the same source. The [FeII] emission is detected from both the jet, the (weak) counter-jet, and from the HH34-S and HH34-N bow shocks. The deconvolved image allows us to resolve jet knots close to about 1\\arcsec from the central source. The morphology of the [FeII] emission is remarkably similar to that of the [SII] emission, and the relative positions of [FeII] and [SII] pea...

    We have constructed a filamentous fungus Aspergillus oryzae that secretes a llama variable heavy-chain antibody fragment (V(HH)) that binds specifically to epidermal growth factor receptor (EGFR) in a culture medium. A major improvement in yield was achieved by fusing the V(HH) with a Taka-amylase A signal sequence (sTAA) and a segment of 28 amino acids from the N-terminal region of Rhizopus oryzae lipase (N28). The yields of secreted, immunologically active anti-EGFR V(HH) reached 73.8 mg/1 in a Sakaguchi flask. The V(HH) fragments were released from the sTAA or N28 proteins by an indigenous A. oryzae protease during cultivation. The purified recombinant V(HH) fragment was specifically recognized and could bind to the EGFR with a high affinity.

  15. Sequential application of ligand and structure based modeling approaches to index chemicals for their hH4R antagonism.

    Directory of Open Access Journals (Sweden)

    Matteo Pappalardo

    Full Text Available The human histamine H4 receptor (hH4R, a member of the G-protein coupled receptors (GPCR family, is an increasingly attractive drug target. It plays a key role in many cell pathways and many hH4R ligands are studied for the treatment of several inflammatory, allergic and autoimmune disorders, as well as for analgesic activity. Due to the challenging difficulties in the experimental elucidation of hH4R structure, virtual screening campaigns are normally run on homology based models. However, a wealth of information about the chemical properties of GPCR ligands has also accumulated over the last few years and an appropriate combination of these ligand-based knowledge with structure-based molecular modeling studies emerges as a promising strategy for computer-assisted drug design. Here, two chemoinformatics techniques, the Intelligent Learning Engine (ILE and Iterative Stochastic Elimination (ISE approach, were used to index chemicals for their hH4R bioactivity. An application of the prediction model on external test set composed of more than 160 hH4R antagonists picked from the chEMBL database gave enrichment factor of 16.4. A virtual high throughput screening on ZINC database was carried out, picking ∼ 4000 chemicals highly indexed as H4R antagonists' candidates. Next, a series of 3D models of hH4R were generated by molecular modeling and molecular dynamics simulations performed in fully atomistic lipid membranes. The efficacy of the hH4R 3D models in discrimination between actives and non-actives were checked and the 3D model with the best performance was chosen for further docking studies performed on the focused library. The output of these docking studies was a consensus library of 11 highly active scored drug candidates. Our findings suggest that a sequential combination of ligand-based chemoinformatics approaches with structure-based ones has the potential to improve the success rate in discovering new biologically active GPCR drugs and

    We present 6 and 20 cm Jansky Very Large Array/Very Large Array observations of the northern head of the HH 80/81/80N jet, one of the largest collimated jet systems known so far, aimed to look for knots farther than HH 80N, the northern head of the jet. Aligned with the jet and 10' northeast of HH 80N, we found a radio source not reported before, with a negative spectral index similar to that of HH 80, HH 81, and HH 80N. The fit of a precessing jet model to the knots of the HH 80/81/80N jet, including the new source, shows that the position of this source is close to the jet path resulting from the modeling. If the new source belongs to the HH 80/81/80N jet, its derived size and dynamical age are 18.4 pc and >9 Multiplication-Sign 10{sup 3} yr, respectively. If the jet is symmetric, its southern lobe would expand beyond the cloud edge resulting in an asymmetric appearance of the jet. Based on the updated dynamical age, we speculate on the possibility that the HH 80/81/80N jet triggered the star formation observed in a dense core found ahead of HH 80N, which shows signposts of interaction with the jet. These results indicate that parsec-scale radio jets can play a role in the stability of dense clumps and the regulation of star formation in the molecular cloud.

  18. NopC Is a Rhizobium-Specific Type 3 Secretion System Effector Secreted by Sinorhizobium (Ensifer) fredii HH103

    Sinorhizobium (Ensifer) fredii HH103 is a broad host-range nitrogen-fixing bacterium able to nodulate many legumes, including soybean. In several rhizobia, root nodulation is influenced by proteins secreted through the type 3 secretion system (T3SS). This specialized secretion apparatus is a common virulence mechanism of many plant and animal pathogenic bacteria that delivers proteins, called effectors, directly into the eukaryotic host cells where they interfere with signal transduction pathways and promote infection by suppressing host defenses. In rhizobia, secreted proteins, called nodulation outer proteins (Nops), are involved in host-range determination and symbiotic efficiency. S. fredii HH103 secretes at least eight Nops through the T3SS. Interestingly, there are Rhizobium-specific Nops, such as NopC, which do not have homologues in pathogenic bacteria. In this work we studied the S. fredii HH103 nopC gene and confirmed that its expression was regulated in a flavonoid-, NodD1- and TtsI-dependent manner. Besides, in vivo bioluminescent studies indicated that the S. fredii HH103 T3SS was expressed in young soybean nodules and adenylate cyclase assays confirmed that NopC was delivered directly into soybean root cells by means of the T3SS machinery. Finally, nodulation assays showed that NopC exerted a positive effect on symbiosis with Glycine max cv. Williams 82 and Vigna unguiculata. All these results indicate that NopC can be considered a Rhizobium-specific effector secreted by S. fredii HH103. PMID:26569401

This may or may not be because agriculture can contribute directly and/or indirectly to economic growth. But it will certainly be critical because poverty is still predominantly a rural phenomenon...... and this looks set to remain for the next two decades at least.

    Context. Atomic jets are a common phenomenon among young stars, being intimately related to disk accretion. Most studies have been performed on jets from pre-main sequence stars. However, to date very little detailed information has been gathered on jets from young embedded low mass sources (the so-called class I stars), especially in the inner jet region. Aims: We exploit a diagnostic analysis based on multiwave spectroscopic observations to infer kinematics and physical conditions of the inner region of the prototypical class I jet from HH34 IRS. Methods: We use a deep X-shooter spectrum covering the wavelength range 350-2300 nm at resolution between 8000 and 18 000 (i.e., ΔV 17-27 km s-1), which allows us to detect lines in a wide range of excitation conditions (from Eup 8000 to 31 000 cm-1 ) and to study their kinematics. Statistical equilibrium and ionization models are adopted to derive the jet main physical parameters. Results: We separately derive the physical conditions for the extended high velocity jet (HVC, Vr -100 km s-1 ) and for the low velocity and compact gas (LVC, Vr -20-50 km s-1) located on-source. Close to the jet base ( 5 × 105 cm-3). The LVC gas has the same density and AV as the HVC, but it is at least a factor of two colder. Iron abundance in the HVC is consistent with the solar value, while it is a factor of 3 subsolar in the LVC, suggesting an origin of the LVC gas from a dusty disk. From the derived total density we infer that the jet mass flux rate is >5 × 10-7M⊙ yr-1. We find that the relationships between accretion luminosity and permitted line luminosity derived for T Tauri stars cannot be directly extended to class I sources embedded in reflection nebulae since the permitted lines are seen through scattered light. An accretion rate of 7 × 10-6M⊙ yr-1 is instead derived from an empirical relationship connecting Ṁacc with L([O i])(HVC). Conclusions: The class I HH34 IRS jet at small scale shares many kinematical and physical

    We study the change in government control of privatized firms in OECD countries. Results indicate that governments typically transfer ownership rights without relinquishing proportional control. Control is commonly retained by leveraging state investments through pyramids, dual-class shares, and golden shares. Indeed, at the end of 2000, after the largest privatization wave in history, governments retain control of 62.4% of privatized firms. In civil law countries, governments tend to retain ...

    Since 2006 a modern laboratory has been developed by IFIN-HH in the underground of Slanic Prahova salt ore. This work presents a short review of previous scientific activities performed in the underground laboratory, in parallel with some plans for the future. A mobile detector for cosmic muon flux measurements has been set up at IFIN-HH, Romania. The device is used to measure the muon flux on different locations at the surface and underground and it consists of two detection layers, each one including four large scintillator plates. A new rotatable detector for measurements of the directional variation of the muon flux has been designed and it is presently under preliminary tests. Built from four layers of sensitive material and using for collecting the signals and directing them to the micro PMTs a new technique, through optical fibers instead wave length shifters, it allows an easy discrimination of the moun flux on the arrival directions of muons. Combining the possibility to rotate and the directionality properties, the underground muon detector is acting like a muon tomography device, being able to scan, using cosmic muons, the rock material above the detector. In parallel new detection system based on SiPM will be also installed in the following weeks. It should be composed by four layers, each layer consisting in 4 scintillator plates what we consider in the following as a module of detection. For this purpose, first two scintillator layers, with the optical fibers positioned on perpendicular directions are put in coincidence with other two layers, 1 m distance from the first two, with similar optical fiber arrangement, thus allowing reconstructing muon trajectory. It is intended also to design and construct an experimental device for the investigation of such radio antennas and the behavior of the signal in rock salt at the Slanic salt mine in Romania. Another method to detect high energy neutrinos is based on the detection of secondary particles resulting

    In this paper, we give efficient algorithms and lower bounds for solving the heavy hitters problem while preserving differential privacy in the fully distributed local model. In this model, there are n parties, each of which possesses a single element from a universe of size N. The heavy hitters problem is to find the identity of the most common element shared amongst the n parties. In the local model, there is no trusted database administrator, and so the algorithm must interact with each of the $n$ parties separately, using a differentially private protocol. We give tight information-theoretic upper and lower bounds on the accuracy to which this problem can be solved in the local model (giving a separation between the local model and the more common centralized model of privacy), as well as computationally efficient algorithms even in the case where the data universe N may be exponentially large.

    We mapped the HH212 Class 0 outflow in SiO(2--1, 5--4) and continuum using the PdBI in its extended configurations. The unprecedented angular resolution (down to 0.34") allows accurate comparison with a new, deep H2 image obtained at the VLT. The SiO emission is confined to a highly-collimated bipolar jet (width 0.35") along the outflow axis. The jet can be traced down to within 500 AU of the protostar, in a region that is heavily obscured in H2 images. Where both species are detected, SiO shows the same overall kinematics and structure as H2, indicating that both molecules are tracing the same material. We find that the high-velocity SiO gas near the protostar is not tracing a wide-angle wind but is already confined to a flow inside a narrow cone of half-opening angle < 6 deg.

    We present deep spectroscopic (3600 - 24700 A) X-shooter observations of the bright Herbig-Haro object HH1, one of the best laboratories to study the chemical and physical modifications caused by protostellar shocks on the natal cloud. We observe atomic fine structure lines, HI, and He, recombination lines and H_2, ro-vibrational lines (more than 500 detections in total). Line emission was analyzed by means of Non Local Thermal Equilibiurm codes to derive the electron temperature and density, and, for the first time, we are able to accurately probe different physical regimes behind a dissociative shock. We find a temperature stratification in the range 4000 - 80000 K, and a significant correlation between temperature and ionization energy. Two density regimes are identified for the ionized gas, a more tenuous, spatially broad component (density about 10^3 cm^-3), and a more compact component (density > 10^5 cm^-3) likely associated with the hottest gas. A further neutral component is also evidenced, having te...

    Complete flux-calibrated spectra covering the spectral range from 6000 A to 2.5 um have been obtained along the HH1 jet and analysed in order to explore the potential of a combined optical/near-IR diagnostic applied to jets from young stellar objects. Important physical parameters have been derived along the jet using various diagnostic line ratios. This multi-line analysis shows, in each spatially unresolved knot, the presence of zones at different excitation conditions, as expected from the cooling layers behind a shock front. In particular, a density stratification in the jet is evident from ratios of various lines of different critical density. In particular, [FeII] lines originate in a cooling layer located at larger distances from the shock front than that generating the optical lines, where the compression is higher and the temperature is declining. The derived parameters were used to measure the mass flux along the jet, adopting different procedures, the advantages and limitations of which are discuss...

    2009-01-01

    We present an analysis of the kinematics and physical properties of the Class I driven jet HH46-47 based on IR medium and low resolution spectroscopy obtained with ISAAC on VLT. Our aim is to study the gas physics as a function of the velocity and distance from the source and compare the results with similar studies performed on other Class I and CTTS jets, as well as with existing models for the jet formation and excitation. The ratios and luminosities of several important diagnostic lines have been used to derive physical parameters. [FeII] and H2 Position Velocity Diagrams (PVDs) have been in addition constructed to study the kinematics. Within 1000-2000 AU from the source the atomic gas presents a wide range of radial velocities. Only the gas component at the highest velocity (HVC) survives at large distances. The H2, shows, close to the source, only a single velocity component at almost zero velocity, while it reaches higer velocities further downstream. Electron densities (ne) and mass ejection fluxes (...

    We present unpublished Spitzer IRAC observations of the HH 1/2 young stellar outflow processed with a high angular resolution deconvolution algorithm that produces sub-arcsecond (approx. 0.6" - 0.8") images. In the resulting mid-infrared images the optically invisible counterjet is detected for the first time. The counterjet is approximately half as bright as the jet at 4.5 micron (the IRAC band that best traces young stellar outflows) and has a length of approx. 10". The NW optical jet itself can be followed back in the mid-IR to the position of the exciting VLA 1 source. An analysis of the IRAC colors indicates that the jet/counterjet emission is dominated by collisionally excited H2 pure rotational lines arising from a medium with a neutral Hydrogen gas density of 1000-2000 per cubic cm and a temperature of 1500 K. The observed jet/counterjet brightness asymmetry is consistent with an intrinsically symmetric outflow with extinction from a dense, circumstellar structure of 6" size (along the outflow axis), ...

    The mechanisms leading to the formation of disks around young stellar objects (YSOs) and to the launching of the associated jets are crucial to the understanding of the earliest stages of star and planet formation. HH 212 is a privileged laboratory to study a pristine jet-disk system. Therefore we investigate the innermost region (uv plane of various velocity channels of the strongest high-excitation lines. The blue- and red-shifted velocity centroids are shifted roughly symmetrically on either side of the jet axis, indicating that the line-of-sight velocity beyond 0.7 km s-1 from systemic is dominated by rotational motions. The velocity increases moving away from the protostar further indicating that the emission of methanol is not associated with a Keplerian disk or rotating-infalling cavity, and it is more likely associated with outflowing gas. We speculate that CH3OH traces a disk wind gas accelerated at the base. The launching region would be at a radius of a few astronomical units from the YSO.

  19. Circular polarimetry reveals helical magnetic fields in the young stellar object HH 135-136

    CERN Document Server

    Chrysostomou, Antonio; Hough, James H

    2007-01-01

    Magnetic fields are believed to have a vital role in regulating and shaping the flow of material onto and away from protostars during their initial mass accretion phase. It is becoming increasingly accepted that bipolar outflows are generated and collimated as material is driven along magnetic field lines and centrifugally accelerated off a rotating accretion disk. However, the precise role of the magnetic field is poorly understood and evidence for its shape and structure has not been forthcoming. Here we report imaging circular polarimetry in the near-infrared and Monte Carlo modelling showing that the magnetic field along the bipolar outflow of the HH 135-136 young stellar object is helical. The field retains this shape for large distances along the outflow, so the field structure can also provide the necessary magnetic pressure for collimation of the outflow. This result lends further weight to the hypothesis - central to any theory of star formation - that the outflow is an important instrument for the r...

    The secondary photometric standard star #79 for the FS Aur field (Henden & Honeycutt 1997) designated as [HH97] FS Aur-79 (GSC 1874 399) is a short period (0.2508 days) eclipsing binary whose light curve is a combination of the $\\beta$ Lyr and BY Dra type variables. High signal-to-noise multi-color photometry were obtained using the USNO 1-m telescope. These light curves show asymmetry at quadrature phases (O'Connell effect), which can be modeled with the presence of star spots. A low resolution spectrum obtained with the 3.5-m WIYN telescope at orbital phase 0.76 is consistent with a spectral type of dK7e and dM3e. A radial velocity curve for the primary star was constructed using twenty-four high resolution spectra from the 9.2 m HET. Spectra show H-alpha and H-beta in emission confirming chromospheric activity and possibly the presence of circumstellar material. Binary star models that simultaneously fit the U, B, V, R and RV curves are those with a primary star of mass 0.59+-0.02 Msun, temperature 410...

    Very little information has been so far gathered on atomic jets from young embedded low mass sources (class I stars), especially in the inner jet region. We exploit multiwave spectroscopic observations to infer physical conditions of the inner region of HH34 IRS, a prototypical class I jet. We use a deep X-shooter spectrum ( lambda = 350-2300 nm, R between 8000 and 18000) detecting lines with upper energies from 8000 to 31000 cm-1 . Statistical equilibrium and ionization models are adopted to derive the jet main physical parameters. We derive the physical conditions for the extended high velocity jet (HVC, V about -100 km/s) and for the low velocity and compact gas (LVC, V about -20-50 \\kms). At the jet base ( 5x10^5 cm-3). The LVC gas has the same density and A_V as the HVC, but it is a factor of two colder. Iron abundance in the HVC is close to solar, while it is 3 times subsolar in the LVC, suggesting an origin of the LVC gas from a dusty disk. We infer a jet mass flux rate > 5x10^{-7} Mo/yr. We find that ...

    2009-01-01

    We investigate the physical structure and dust reprocessing in the shocks along the beam of a number of classical Herbig-Haro jets in the Orion and Lupus molecular cloud. Spectral diagnostic techniques are applied to obtain the jet physical conditions from the ratios between selected forbidden lines. The presence of dust grains is investigated by estimating the gas-phase abundance of calcium with respect to its Solar value. We find the electron density, ne, varies between 0.05-4 10^3 cm^-3, the ionisation fraction, xe, is 0.01-0.7, the temperature, te, ranges between 0.6-3 10^4 K, and the hydrogen density between 0.01-6 10^4 cm^-3. Interestingly, in the HH 111 jet, ne, xe, and te, peak in the High Velocity Interval (HVI) of the strongest working surfaces, confirming the prediction from shocks models. Calcium turns out to be depleted with respect to its Solar value, but its gas-phase abundance is higher than that estimated in the interstellar medium in Orion. The depletion is high (up to 80%) along the low-exc...

    2006-01-01

    We present high spatial resolution optical integral field spectroscopy of a collimated Herbig-Haro jet viewed nearly edge-on. Maps of the line emission, velocity centroid, and velocity dispersion were generated for the H$\\alpha$ and [S II] emission features from the inner collimated jet and exciting source region of the HH 34 outflow. The kinematic structure of the jet shows several maxima and minima in both velocity centroid value and velocity dispersion along the jet axis. Perpendicular to the flow direction the velocity decreases outward from the axis to the limb of the jet, but the velocity dispersion increases. Maps of the electron density structure were derived from the line ratio of [S II] 6731/6716 emission. We have found that the jet exhibits a pronounced ``striped'' pattern in electron density; the high $n_e$ regions are at the leading side of each of the emission knots in the collimated jet, and low $n_e$ regions in the down-flow direction. On average, the measured electron density decreases outwar...

    We are aiming at the observational estimation of the relative contribution to the cooling by CO and H2O, as this provides decisive information for the understanding of the oxygen chemistry behind interstellar shock waves. Methods. The high sensitivity of HIFI, in combination with its high spectral resolution capability, allows us to trace the H2O outflow wings at unprecedented signal-to-noise. From the observation of spectrally resolved H2O and CO lines in the HH52-54 system, both from space and from ground, we arrive at the spatial and velocity distribution of the molecular outflow gas. Solving the statistical equilibrium and non-LTE radiative transfer equations provides us with estimates of the physical parameters of this gas, including the cooling rate ratios of the species. The radiative transfer is based on an ALI code, where we use the fact that variable shock strengths, distributed along the front, are naturally implied by a curved surface. Based on observations of CO and H2O spectral lines, we conclud...

    We present SiO J=8-7 (347.3 GHz) observations towards HH 212 using the ASTE telescope. Our observations with a 22''-diameter beam show that the SiO emission is highly concentrated within 1' of the driving source. We carefully compare the SiO observations with archival H_2 1-0 S(1) images and published H_2 echelle spectra. We find that, although the SiO velocities closely match the radial velocities seen in H_2, the distribution of H_2 and SiO emission differ markedly. We attribute the latter to the different excitation conditions required for H_2 and SiO emission, particularly the higher critical density (n_H2 ~10^8 cm^-3) of the SiO J=8-7 emission. The kinematic similarities imply that the H_2 and SiO are associated with the same internal working surfaces. We conclude that the SiO J=8-7 emission has a potential to probe the jet/wind launching region through interferometric observations in the future, particularly for the youngest, most deeply embedded protostars where IR observations are not possible.

    A 3 MV Tandetron™ accelerator system has been installed and commissioned at the “Horia Hulubei” National Institute for Physics and Nuclear Engineering – IFIN-HH, Măgurele, Romania. The main purpose of this machine is to strengthen applied nuclear physics research ongoing in our institute for more than four decades. The accelerator system was developed by High Voltage Engineering Europa B.V. (HVE) and comprises three high energy beam lines. The first beam line is dedicated to ion beam analysis (IBA) techniques: Rutherford Backscattering Spectrometry – RBS, Nuclear Reaction Analysis – NRA, Particle Induced X-ray and γ-ray Emission – PIXE and PIGE and micro-beam experiments – μ-PIXE. The second beam line is dedicated to high energy ion implantation experiments and the third beam line was designed mainly for nuclear cross-sections measurements used in nuclear astrophysics. A unique feature, the first time in operation at an accelerator facility is the Na charge exchange canal (CEC), which is used to obtain high intensity beams of He{sup −} of at least 3 μA. The results of the acceptance tests demonstrate the huge potential of this new facility in various fields, from IBA to radiation hardness studies and from medical or environmental applications to astrophysics. The main features of the accelerator are presented in this paper.

    A 3 MV Tandetron™ accelerator system has been installed and commissioned at the "Horia Hulubei" National Institute for Physics and Nuclear Engineering - IFIN-HH, Măgurele, Romania. The main purpose of this machine is to strengthen applied nuclear physics research ongoing in our institute for more than four decades. The accelerator system was developed by High Voltage Engineering Europa B.V. (HVE) and comprises three high energy beam lines. The first beam line is dedicated to ion beam analysis (IBA) techniques: Rutherford Backscattering Spectrometry - RBS, Nuclear Reaction Analysis - NRA, Particle Induced X-ray and γ-ray Emission - PIXE and PIGE and micro-beam experiments - μ-PIXE. The second beam line is dedicated to high energy ion implantation experiments and the third beam line was designed mainly for nuclear cross-sections measurements used in nuclear astrophysics. A unique feature, the first time in operation at an accelerator facility is the Na charge exchange canal (CEC), which is used to obtain high intensity beams of He- of at least 3 μA. The results of the acceptance tests demonstrate the huge potential of this new facility in various fields, from IBA to radiation hardness studies and from medical or environmental applications to astrophysics. The main features of the accelerator are presented in this paper.

    We present an analysis of H{alpha} spectra of the HH 34 jet with two-dimensional spectral resolution. We carry out multi-Gaussian fits to the spatially resolved line profiles and derive maps of the intensity, radial velocity, and velocity width of each of the components. We find that close to the outflow source we have three components: a high (negative) radial velocity component with a well-collimated, jet-like morphology; an intermediate velocity component with a broader morphology; and a positive radial velocity component with a non-collimated morphology and large linewidth. We suggest that this positive velocity component is associated with jet emission scattered in stationary dust present in the circumstellar environment. Farther away from the outflow source, we find only two components (a high, negative radial velocity component, which has a narrower spatial distribution than an intermediate velocity component). The fitting procedure was carried out with the new AGA-V1 code, which is available online and is described in detail in this paper.

On s’attache d’abord à décrire ces comportements et à identifier les principes à partir desquels les acteurs les justifient. On propose ensuite deux hypothèses susceptibles de rendre compte de la cohérence constatée. La première suggère que cette cohé­rence est en partie construite par le discours des interviewés. La seconde s’interroge sur les mécanismes de socialisation. Trois mécanismes sont iden­tifiés : les tensions identitaires que les personnes ressentent lorsqu’elles s’écar­tent des principes évoqués ; les contrôles, formels et surtout informels, qu’elles exercent les unes sur les autres ; la hiérarchie qui s’instaure dans le champ de la viticulture biologique, en raison précisément de la plus ou moins forte cohé­rence des comportements. On montre que ces mécanismes combinent leurs effets pour produire une socialisation puissante et uniforme, qui fait des viti­culteurs biologiques interviewés des individus beaucoup plus intégrés que ce que prédisent des théories sociologiques qui mettent en avant la diversité, ou encore l’éclatement de l’expérience de l’individu contemporain.This contribution looks at the strong level of coherence observed in the behaviours, both professional and private, of a small sample of Alsatian winegrowers whom we interviewed at length.

    At high proton-beam energies, beam-induced synchrotron radiation is an important source of heating, of beam-related vacuum pressure increase, and of primary photoelectrons, which can give rise to an electron cloud. We use the Synrad3D code developed at Cornell to simulate the photon distributions in the arcs of the LHC, HL-LHC, and FCC-hh. Specifically, for the LHC we study the effect of the “sawtooth” chamber, for the HL-LHC the consequences of the ATS optics with large beta beating in the arcs, and for the FCC-hh the effect of a novel beam-screen design, with a long slit surrounded by a “folded” antechamber.

    We present Very Large Array NH{sub 3} and Plateau de Bure Interferometer NH{sub 2}D and HN{sup 13}C observations of the star-forming core ahead of HH 80N, the optically obscured northern counterpart of the Herbig-Haro objects HH 80/81. The main goal is to determine the kinematical information of the high density regions of the core (n ∼> 10{sup 5} cm{sup –3}) missed in previous works due to the depletion of the species observed (e.g., CS). The obtained maps show different kinematical signatures between the eastern and western parts of the core, suggesting a possible dynamical interaction of the core with the HH 80/81/80N outflow. The analysis of the position-velocity (P-V) plots of these species rules out a previous interpretation of having a molecular ring-like structure with a radius of 6 × 10{sup 4} AU traced by CS infalling onto a central protostar found in the core (IRS1). A high degree of NH{sub 3} deuteration, with respect to the central part of the core harboring IRS1, is derived in the eastern part, where a dust condensation (SE) is located. This deuteration trend of NH{sub 3} suggests that SE is in a pre-stellar evolutionary stage, earlier than that of IRS1. Since SE is the closest condensation to the HH 80N/81/80N outflow, in a case of outflow-core dynamical interaction, it should be perturbed first and be the most evolved condensation in the core. Therefore, the derived evolutionary sequence for SE and IRS1 makes outflow triggered star formation on IRS1 unlikely.

    NAD(+)-dependent DNA ligases (LigAs) are ubiquitous in bacteria and essential for growth. LigA enzymes have a modular structure in which a central catalytic core composed of nucleotidyltransferase and oligonucleotide-binding (OB) domains is linked via a tetracysteine zinc finger to distal helix-hairpin-helix (HhH) and BRCT (BRCA1-like C-terminal) domains. The OB and HhH domains contribute prominently to the protein clamp formed by LigA around nicked duplex DNA. Here we conducted a structure-function analysis of the OB and HhH domains of Escherichia coli LigA by alanine scanning and conservative substitutions, entailing 43 mutations at 22 amino acids. We thereby identified essential functional groups in the OB domain that engage the DNA phosphodiester backbone flanking the nick (Arg(333)); penetrate the minor grove and distort the nick (Val(383) and Ile(384)); or stabilize the OB fold (Arg(379)). The essential constituents of the HhH domain include: four glycines (Gly(455), Gly(489), Gly(521), Gly(553)), which bind the phosphate backbone across the minor groove at the outer margins of the LigA-DNA interface; Arg(487), which penetrates the minor groove at the outer margin on the 3 (R)-OH side of the nick; and Arg(446), which promotes protein clamp formation via contacts to the nucleotidyltransferase domain. We find that the BRCT domain is required in its entirety for effective nick sealing and AMP-dependent supercoil relaxation.

    Full Text Available Public organizations are no longer synonymous with governmental agencies but include many for-profit service organizations as well as the third sector, which is made up of the private NPOs. Such diverse organizations. meet the publicness criterion to the extent that they cannot ignore publicness when dealing with development of strategy. Competitive models of strategic management have little use in organizations with significant degrees of publicness. Instead, a strategy should be sought which enhances cooperation and collaboration. Strategic management in public settings must identify the beliefs and demands of key stakeholders and deal with elaborate fictions held by these individuals to premise development and guide implementation. Strategic managers must carefully collaborate with their oversight body as they fashion a strategy.

    We investigate the plausibility of detecting X-ray emission from a stellar jet that impacts a dense molecular cloud, a scenario that may be typical for classical T Tauri stars with jets in dense star-forming complexes. We first model the impact of a jet against a dense cloud using two-dimensional axisymmetric hydrodynamic simulations, exploring different configurations of the ambient environment. Then, we compare our results with XMM-Newton observations of the Herbig–Haro object HH 248, where extended X-ray emission aligned with the optical knots is detected at the edge of the nearby IC 434 cloud. Our simulations show that a jet can produce plasma with temperatures up to 10{sup 7} K, consistent with production of X-ray emission, after impacting a dense cloud. We find that jets denser than the ambient medium but less dense than the cloud produce detectable X-ray emission only at impact with the cloud. From an exploration of the model parameter space, we constrain the physical conditions (jet density and velocity and cloud density) that reproduce the intrinsic luminosity and emission measure of the X-ray source possibly associated with HH 248 well. Thus, we suggest that the extended X-ray source close to HH 248 corresponds to a jet impacting a dense cloud.

    We present several molecular line emission arcsec and subarcsec observations obtained with the Submillimeter Array (SMA) in the direction of the massive protostar IRAS 18162-2048, the exciting source of HH 80-81. The data clearly indicates the presence of a compact (radius~425-850 AU) SO2 structure, enveloping the more compact (radius~150 AU) 1.4 millimeter dust emission (reported in a previous paper). The emission spatially coincides with the position of the prominent thermal radio jet which terminates at the HH 80-81 and HH 80N Herbig-Haro objects. Furthermore, the molecular emission is elongated in the direction perpendicular to the axis of the thermal radio jet, suggesting a disk-like structure. We derive a total dynamic mass (disk-like structure and protostar) of 11-15 msun. The SO2 spectral line data also allow us to constrain the structure temperature between 120-160 K and the volume density \\geq 2 \\times 10^9 cm3.

  10. Accurate quantum thermal rate constants for the three-dimensional H+H2 reaction

    Park, Tae Jun; Light, J. C.

    1989-07-01

    The rate constants for the three-dimensional H+H2 reaction on the Liu-Siegbahn-Truhlar-Horowitz (LSTH) surface are calculated using Pack-Parker hyperspherical (APH) coordinates and a C2v symmetry adapted direct product discrete variable representation (DVR). The C2v symmetry decomposition and the parity decoupling on the basis are performed for the internal coordinate χ. The symmetry decomposition results in a block diagonal representation of the flux and Hamiltonian operators. The multisurface flux is introduced to represent the multichannel reactive flux. The eigenvalues and eigenvectors of the J=0 internal Hamiltonian are obtained by sequential diagonalization and truncation. The individual symmetry blocks of the flux operator are propagated by the corresponding blocks of the Hamiltonian, and the J=0 rate constant k0(T) is obtained as a sum of the rate constants calculated for each block. k0(T) is compared with the exact k0(T) obtained from thermal averaging of the J=0 reaction probabilities; the errors are within 5%-20% up to T=1500 K. The sequential diagonalization-truncation method reduces the size of the Hamiltonian greatly, but the resulting Hamiltonian matrix still describes the time evolution very accurately. For the J≠0 rate constant calculations, the truncated internal Hamiltonian eigenvector basis is used to construct reduced (JKJ) blocks of the Hamiltonian. The individual (JKJ) blocks are diagonalized neglecting Coriolis coupling and treating the off-diagonal KJ±2 couplings by second order perturbation theory. The full wave function is parity decoupled. The rate constant is obtained as a sum over J of (2J+1)kJ(T). The time evolution of the flux for J≠0 is again very accurately described to give a well converged rate constant.

    The secondary photometric standard star number 79 for the FS Aur field (Henden & Honeycutt 1997), designated as [HH97] FS Aur-79 (GSC 1874-399), is a short-period (0.2508 days) eclipsing binary whose light curve is a combination of the β Lyr and BY Dra type variables. High signal-to-noise ratio multicolor photometry was obtained using the US Naval Observatory 1 m telescope. These light curves show asymmetry at quadrature phases (the O'Connell effect), which can be modeled with the presence of starspots. A low-resolution spectrum obtained with the 3.5 m Wisconsin-Indiana-Yale-NOAO telescope at orbital phase 0.76 is consistent with a spectral type of dK7e and dM3e. A radial velocity curve for the primary star was constructed using 24 high-resolution spectra from the 9.2 m Hobby-Eberly Telescope. Spectra show Hα and Hβ in emission confirming chromospheric activity and possibly the presence of circumstellar material. Binary star models that simultaneously fit the U, B, V, R, and radial velocity curves are those with a primary star of mass 0.59+/-0.02 Msolar, temperature 4100+/-25 K, and mean radius 0.67 Rsolar, just filling its Roche lobe, and a secondary star of mass 0.31+/-0.09 Msolar, temperature 3425+/-25 K, and mean radius 0.48 Rsolar, just within its Roche lobe. An inclination angle of 83deg+/-2deg with a center-of-mass separation of 1.62 Rsolar is also derived. Starspots, expected for a rotation period of less than 1 day, had to be included in the modeling to fit the O'Connell effect.

  12. SWOT analysis & privatization in Croatia

    Full Text Available Legal framework for privatization in Croatia was based on two key laws: the Transformation Act of 1991, and the Privatization Act of 1993, amended in 1996. Early start of privatization process in 1990s in Croatia was marked by the transformation of socially-owned companies into stock holding companies or limited liability companies. The first step (1991-1993 of this process of almost 2700 companies which entered privatization was their evaluation and transformation into private ownership entities. The second step (1994- 1997 consisted of privatization of CPF portfolio. The portfolios change constantly, not only as a result of privatization but also because companies themselves change, as does their position in the market. The third step (1998 in the privatization process was voucher privatization. Privatization of large infrastructure and utility companies designated as public enterprises began in 1999 (Croatian Telecom and INA in 2002 (public enterprises are privatized on the basis of separate laws. Attempts to discuss privatization in Croatia in terms of SWOT analysis have been motivated by the stark difference among Croatian professional economists in an appraisal of Croatia's performance during the transition process in general and of the privatization process in particular. Therefore we considered the elements of SWOT analysis to be an acceptable way to delve into the confusing world of bickering arguments on the state and perspective of the Croatia's privatization process. In this paper we have tried to provide an impartial approach by employing two criteria i.e. strength and weaknesses in judging the events and results of the privatization process in Croatia. Strength of the overall privatization process can be mostly ascribed to the institutional swiftness on micro as well as on macro level. On the micro level 80% of the companies were formally privatized in the first two years despite unfavorable external conditions comprising the

    Recently, there has been much effort to find effective ingredients which can prevent or retard cutaneous skin aging after topical or systemic use. Here, we investigated the effects of the atomic hydrogen surrounded by water molecules, H(H2O)m, on acute UV-induced responses and as well as skin aging. Interestingly, we observed that H(H2O)m application to human skin prevented UV-induced erythema and DNA damage. And H(H2O)m significantly prevented UV-induced MMP-1, COX-2, IL-6 and IL-1β mRNA expressions in human skin in vivo. We found that H(H2O)m prevented UV-induced ROS generation and inhibited UV-induced MMP-1, COX-2 and IL-6 expressions, and UV-induced JNK and c-Jun phosphorylation in HaCaT cells. Next, we investigated the effects of H(H2O)m on intrinsically aged or photoaged skin of elderly subjects. In intrinsically aged skin, H(H2O)m application significantly reduced constitutive expressions of MMP-1, IL-6, and IL-1β mRNA. Additionally, H(H2O)m significantly increased procollagen mRNA and also decreased MMP-1 and IL-6 mRNA expressions in photoaged facial skin. These results demonstrated that local application of H(H2O)m may prevent UV-induced skin inflammation and can modulate intrinsic skin aging and photoaging processes. Therefore, we suggest that modifying the atmospheric gas environment within a room may be a new way to regulate skin functions or skin aging. PMID:23637886

    A desert-grown Halimodendron halodendron ethylene-responsive element binding factor gene (HhERF2), which encodes a 245 amino acids protein containing a conserved AP2/EREBP domain, was isolated through the rapid amplification cDNA end (RACE) method. Sequence and phylogenetic analysis indicated that HhERF2 was classified into the B-2 group of ERF subfamily. Semiquantitative RT-PCR showed that HhERF2 was greatly induced by treatments with high-salt, drought and low temperature in H. halodendron seedlings. The expression vector containing HhERF2 and Populus euphratica dehydration- responsive element binding protein (PeDREB2a) genes driven by rd29A promoter was constructed and transferred into cotton (Gossypium hirsutum L.) by non-tissue culture Agrobacterium-mediated genetic transformation system. The transformation and expression of HhERF2 and PeDREB2a were identified by PCR and RT-PCR. Analyses of physiological function indicated that transgenic cottons had improved seeds germination, tolerance to drought and highsalt stresses. Agronomic evaluation in the field exhibited that transgenic lines presented a dwarf phenotype and improved further in the yield and characters. These results demonstrated that overexpressed both HhERF2 and PeDREB2a transcription factor genes in cotton induced elevated tolerance to drought and high-salt stresses.

    2015-06-01

    Full Text Available Extract:The current importance of public debt requires governments to increasingly shift towards Public-Private Partnerships (PPPs. They are long-term contracts of private financing method providing or contributing to public service. The payment is made by the public partner and/or users of the service.The World Health Organization (WHO defines this type of partnership as ‘‘a means to bring together a set of actors for the common goal of improving the health of populations based on mutually agreed roles and principles.’’Historically, the principle of PPP was established by the Private Finance Initiative (PFI, launched by the conservative government of John Major in 1992. It was from this moment that this model quickly spread to the rest of the world. In the mid-90s and from Australia, PPP agreement began to become part of the language of governments. In 1997, Labour with Tony Blair leading, strongly developed this management method, first and particularly in hospitals and then, in the entire public sector and spreading to the Royal Navy. Today, 10-15% of British public investments are made using PFI method....

  8. HH 666: different kinematics from H α and [Fe II] emission provide a missing link between jets and outflows

    Science.gov (United States)

    Reiter, Megan; Smith, Nathan; Kiminki, Megan M.; Bally, John

    2015-06-01

    HH 666 is an externally irradiated protostellar outflow in the Carina nebula for which we present new near-IR [Fe II] spectra obtained with the Folded-Port Infrared Echellette spectrograph at Magellan Observatory. Earlier H α and near-IR [Fe II] imaging revealed that the two emission lines trace substantially different morphologies in the inner ˜40 arcsec of the outflow. H α traces a broad cocoon that surrounds the collimated [Fe II] jet that extends throughout the parent dust pillar. New spectra show that this discrepancy extends to their kinematics. Near-IR [Fe II] emission traces steady, fast velocities of ±200 km s-1 from the eastern and western limbs of the jet. We compare this to a previously published H α spectrum that reveals a Hubble-flow velocity structure near the jet-driving source. New, second-epoch Hubble Space Telescope (HST)/Advanced Camera for Surveys (ACS) H α images reveal the lateral spreading of the H α outflow lobe away from the jet axis. H α proper motions also indicate a sudden increase in the mass-loss rate ˜1000 yr ago, while steady [Fe II] emission throughout the inner jet suggest that the burst is ongoing. An accretion burst sustained for ˜1000 yr is an order of magnitude longer than expected for FU Orionis outbursts, but represents only a small fraction of the total age of the HH 666 outflow. Altogether, available data suggests that [Fe II] traces the highly collimated protostellar jet while H α traces the entrained and irradiated outflow. HH 666 appears to be a missing link between bare jets seen in H II regions and entrained molecular outflows seen from embedded protostars in more quiescent regions.

  9. Control of the private security sector in foreign countries

    Stajić Ljubomir

    2012-01-01

    Full Text Available All modern states today have organized and regulated system of security that includes different role of private security sector which is defined and limited by law. The law represents the basis and limits the activities of all social subjects including the private security sector. Today, legal regulation of private security industry has gone very far in modern democratic societies. So-called model of control through the contract with the business model is abandoned and approach to the model of control by the state is accepted. The new model has almost the same elements used by the state when it comes to controlling the public sector or the police. Analyses indicate that issues related to the control of the private security can be legally regulated in a manner that is typically European, but also have an entirely different approach and variety of combinations that regulate the functioning of private security sector respecting national characteristics. The paper represents the main principles of control of private security abroad with special emphasis on the possible role of international law.

  10. Legal significance of the private security sector in Kosovo

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available Privatization of the security sector is considered a new phenomenon in the post communist society. The security system has been under a total monopol of the state institutions. Therefore, even the legal adjustment of this system is considered that only state institutions are entitled for provision of the security services, by excluding participation of civic organizations from this activity. Beside this, state enterprises have been obliged to establish its safet structures for property protection and involved employers in enterprises. Immediately after the conflictual period the privatization of the security sector was rapidly increased, including various parts of society. In Kosovo immediately after the conflictual period there was legal gaps, which means that the private security sector has not been adjusted and as a result of this has been uncontrolled and without supervision. Therefore in 2000 the UNMIK administration has undertaken measures and has carried out the first act which has regulated this sector in Kosova. The draft law has undergone significant changes starting from the title. Saying in more common manner, “Draft law for private security” is amended in the LAW no. 04/L-004.2001 for private security services, and this amendment of the private security sector is based in the above mentioned law.

  11. Public-private interactions in global food safety governance.

    Science.gov (United States)

    Lin, Ching-Fu

    2014-01-01

    In response to an apparent decline in global food safety, numerous public and private regulatory initiatives have emerged to restore public confidence. This trend has been particularly marked by the growing influence of private regulators such as multinational food companies, supermarket chains and non-governmental organizations (NGOs), who employ private standards, certification protocols, third-party auditing, and transnational contracting practices. This paper explores how the structure and processes of private food safety governance interact with traditional public governance regimes, focusing on Global Good Agricultural Practices (GlobalGAP) as a primary example of the former. Due to the inefficiency and ineffectiveness of public regulation in the face of global problems, private governance in food safety has gradually replaced states' command-and-control regulation with more flexible, market-oriented mechanisms. The paper concludes by emphasizing the importance of constructive regime interaction instead of institutional boundary building to global food safety governance. Public and private ordering must each play a role as integral parts of a larger, dynamic and evolving governance complex.

  16. 中国企业的学习型组织文化:基于人口统计变量、企业属性、工作满意度和组织绩效的实证分析%The culture of learning organizations in Chinese state-owned and privately-owned enterprises: An empirical study

    Institute of Scientific and Technical Information of China (English)

    王晓辉; 杨百寅

    2007-01-01

    By using a Western concept-the instrument called dimensions of learning organization questionnaire (DLOQ), and the data collected from 919 employees in nine companies located in Guangdong Province, China, the present empirical study explores the culture of learning organizations in Chinese business settings. Findings suggest that the DLOQ is applicable to the context of China as well, and those demographic variables, such as age and educational level,together with the types of ownership of Chinese companies, such as state-owned enterprises (SOEs) and privately-owned enterprises (POEs), suggest differences in the culture of learning organizations. Results also indicate that the learning organization culture of a firm has strongly positive impact on employees' job satisfaction and perceived organizational performance. Two implications should be noted. First, as employees in middle age and with college education show the strongest sense of improving the learning culture, it can be inferred that demographic characters and groups may in fluence the organization's learning culture differently. Second, as POEs have a better learning atmosphere than SOEs, it can be inferred that POEs have a stronger competitiveness than SOEsin terms of learning ability and organizational performance. To indigenize the Western construct and instrument of learning organizations, the present study, as an exploratory research, gives substantial knowledge on the subject and seeks to fill the gap in the literature, despite the limitations of cultural nuances and a narrowly-concentrated sample.

    2015-01-01

    Hepatic iron overload is common in patients undergoing hematopoietic cell transplantation and may be associated with hepatic injury. Here iron overload model of HH4 cells induced by FAC (ferric ammonium citrate) was established. The total proteins of HH4 cells treated with or without FAC were extracted, and total glycopeptides were isolated by an ultrafiltration unit. The glycopeptides were enzymatically hydrolyzed by Peptide-N-glycosidase F (PNGase F) and the released N-linked glycans were desalinated using Sepharose 4B. The structures of the purified N-glycans were identified by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF/TOF-MS). Furthermore, the comparative expression of N-glycans was analyzed by lectin immunohistochemistry. The result indicated that 16 N-glycans were differentially expressed in HH4 cells treated with or without FAC. The levels of high-mannose-type N-glycans were decreased significantly, while the expression of hybrid type, complex type, bisecting type, fucosylation and sialylation of glycans were enhanced markedly in FAC-treated HH4 cells. Consistent with MS analysis, lectin immunohistochemistry study showed that the binding affinity to lectin ConA was reduced in FAC-treated HH4 cells, but the binding affinities to 4 lectins PHA-E, AAL, LCA and MAL-II were significantly increased. The present research provides the fundamental observations for further understanding functional roles of differential expression of N-linked glycans in iron-overload HH4 cells.%肝脏铁过载是血液系统疾病患者进行骨髓移植后的典型并发症之一,长期铁过载可引发肝脏细胞凋亡和器官损坏,然而铁过载的分子调控机理迄今仍不清楚。以培养的枸橼酸铁铵过载人肝细胞HH4和正常人肝细胞HH4为研究对象,细胞裂解提取总蛋白,分子筛超滤管分离获得总糖肽,PNGase F酶解释放出N-糖链,Sepharose 4B除盐纯化N-糖链,再利用基质

    Full Text Available The privatization process after the 90’s has laid the foundation stone for Albania’s EU integration, not only in the economic, but also in its legal field. In the late 80’s an ideological, political, economic system disintegrated and in Albania as in all countries of Eastern Europe, democracy, free market economy and the rule of law, based on private property and free market economy were the foundation of the transformation. But the way this transformation had to be mastered was not clearly defined. For more than 40 years, Albanian citizens were faced with the communist ideology as the basis of state government regulation. This ideology stated that, all citizens had contributed the same way and in the same extent during socialism for the construction of state and social property. In Albania, as in all other countries of Eastern Europe, the so-called “Rent seekers” were transformed into Oligarchs and Owners of the privatized state-property for little money. In this context, this process was accompanied by the deficiency of accurate economic statistics, privatization strategies, foreign investors, a bad policy implementation as well as delays in the framework of immediately needed reforms (Åslund 2013. Main objective of this article is the Analysis of the privatization process in Albania through statistics.

    2014-01-01

    Full Text Available We analyze how cooperatives in Northern Italy (Alto Adige and Trentino compete with private wineries regarding product quality and reputation, i.e. if firm organization affects wine quality and winery reputation. Moreover, we examine if cooperatives with deep roots in their local economy specialize in specific regional denomination rules (i.e. DOC, IGT. Compared to private wineries, cooperatives face additional challenges in order to raise wine quality, among them appropriate incentives that induce individual growers to supply high quality grapes (e.g. vineyard management and grape pricing schemes to lower yields. The quality reputation of a winery with consumers depends crucially on its winemaking skills. Wine regions differ with respect to climatic conditions and quality denomination rules. Assuming similar climatic conditions within wine regions as well as winemaking skills between firms, incentive schemes to induce individual growers to supply high quality grapes and quality denomination rules remain crucial determinants of wine quality and winery reputation when comparing different regions and firm organizational forms. The data set analyzed allows differentiating local cooperatives vs. private wineries and denotes retail prices, wine quality evaluations, indicators for winery reputation, and distinct denomination rules. We employ a hedonic pricing model in order to test the following hypothesis: First, wines produced by cooperatives suffer a significant reputation and/or wine quality discount relative to wines from private producers. Second, cooperatives and/or private wineries specialize in specific wine denominations for which they receive a price premium relative the competing organizational form. Our results are mixed. However, we reject the hypothesis that cooperatives suffer a reputation/wine quality discount relative to private producers for the Alto Adige wine region. Moreover, we find that regional cooperatives and private

    Pomeroy, Amanda M; Koblinsky, Marge; Alva, Soumya

    2014-07-01

    Over the past two decades, multilateral organizations have encouraged increased engagement with private healthcare providers in developing countries. As these efforts progress, there are concerns regarding how private delivery care may effect maternal health outcomes. Currently available data do not allow for an in-depth study of the direct effect of increasing private sector use on maternal health across countries. As a first step, however, we use demographic and health surveys (DHS) data to (1) examine trends in growth of delivery care provided by private facilities and (2) describe who is using the private sector within the healthcare system. As Asia has shown strong increases in institutional coverage of delivery care in the last decade, we will examine trends in six Asian countries. We hypothesize that if the private sector competes for clients based on perceived quality, their clientele will be wealthier, more educated and live in an area where there are enough health facilities to allow for competition. We test this hypothesis by examining factors of socio-demographic, economic and physical access and actual/perceived need related to a mother's choice to deliver in a health facility and then, among women delivering in a facility, their use of a private provider. Results show a significant trend towards greater use of private sector delivery care over the last decade. Wealth and education are related to private sector delivery care in about half of our countries, but are not as universally related to use as we would expect. A previous private facility birth predicted repeat private facility use across nearly all countries. In two countries (Cambodia and India), primiparity also predicted private facility use. More in-depth work is needed to truly understand the behaviour of the private sector in these countries; these results warn against making generalizations about private sector delivery care.

    The U.S. Department of Energy (DOE) is planning a two-phased program for the remediation of Hanford tank waste. Phase 1 is a pilot program to demonstrate the procurement of treatment services. The volume of waste treated during the Phase 1 is a small percentage of the tank waste. During Phase 2, DOE intends to procure treatment services for the balance of the waste. The TWRS Privatization Process Technical Baseline (PPTB) provides a summary level flowsheet/mass balance of tank waste treatment operations which is consistent with the tank inventory information, waste feed staging studies, and privatization guidelines currently available. The PPTB will be revised periodically as privatized processing concepts are crystallized.

    2008-01-01

    Learning problems form an important category of computational tasks that generalizes many of the computations researchers apply to large real-life datasets. We ask: what concept classes can be learned privately, namely, by an algorithm whose output does not depend too heavily on any one input or specific training example? Our goal is a complexity-theoretic classification of learning problems efficiently solvable with the privacy restriction, that is, by epsilon-differentially private algorithms. We consider four private learning models: local interactive (LI), learning non-interactive (LNI), centralized interactive (CI), and centralized non-interactive (CNI). We give a characterization of these models with respect to standard learning models, PAC and SQ. We show that for learning problems LNI is a strict subset of LI, and LI is a strict subset of CNI=CI. This characterization takes into account the number of samples required for learning, but not computational efficiency. We also present a partial characteriz...

  8. The physical properties of the HH 30 jet from HST and ground-based data

    Science.gov (United States)

    Bacciotti, Francesca; Eislöffel, Jochen; Ray, Thomas P.

    1999-10-01

    We investigate the physical properties of the HH 30 jet by applying the spectroscopic diagnostic technique described in Bacciotti & Eislöffel (\\cite{be99}) to ground-based spectra and Hubble Space Telescope (HST) calibrated emission-line images. We derive the variation along the beam of the ionization fraction xe, of the total hydrogen density n_H and of the average excitation temperature Te, with a spatial sampling of 0.1" to 0.6" (depending on the dataset used) near the source of the flow and of 1.8" further out. In the jet xe rapidly rises from 0.065 at 0.2" to 0.1 at 0.4", and then slowly increases up to 0.140 within 2'' from the source. From 2.4" to 12.5", xe decreases very slowly down to a value of 0.04. The slow recombination in the outermost collimated part is consistent with a flow opening angle of about 2(deg) . At the beginning of the jet n_H is at least ~ 10(5) cm(-3) , but it decreases to 5 10(4) cm(-3) within the first arcsecond and then slowly falls to 10(4) cm(-3) at large distance from the source. On average Te decreases from ~ 2 10(4) K to 10(4) K within the first arcsecond of the jet, then it slowly decays to 6000-7000 K. In the faint counter-jet, which appears to be substantially more excited than the jet, xe rises from 0.07 up to 0.35 at 2-3 arcsec from the source, n_H decreases from about 8 10(4) cm(-3) to a few 10(3) cm(-3) , while Te is scattered around 1.2-1.3 10(4) K. A comparison between the observed and calculated line fluxes shows that the filling factor is of order unity in this flow. The emission-weighted jet width calculated with the parameters that we derive is in good agreement with the observed FWHM; we find, however, that the jet radius apparently goes to zero at the source location, defining an initial full opening angle of about 10(deg) . The intensity peaks, i.e. the knots, are clearly correlated with local temperature maxima. The ionization fraction and the electron and total densities do not show any evident increase at

ABSTRACT. The presence of collimated outflows associated with young stellar objects is a common phenomenon in star-fortning regions. These jets frequently show a chain of emission-line regions several of which have long been known as Herbig-Haro (H-H) objects. In this paper we examine the possibility that these knots are condensations produced by thermal instability in an expanding plasma , recombination and emission-line radiation losses. We show that the minimum value of = P /PNo under isobaric conditions for the growth of a thermal instability 0is = (6/5)1 [9/(STcN)e) - 3/2]; where P0 is the particle pressure, NQ tWe magnetic pressure, N) the expansion rate

  10. Privatization and emergency medical services.

    Osborne and Gaebler's Reinventing Government has sparked discussion amongst elected officials, civil servants, the media, and the general public regarding advantages of privatizing government services. Its support stems from an effort to provide services to municipalities while reducing taxpayer expenditure. Many echo the sentiment of former New York Governor Mario Cuomo, who said, "It is not government's obligation to provide services, but to see that they're provided." Even in the area of public safety, privatization has found a "market." In many localities, privatizing Emergency Medical Services (EMS) is a popular and successful method for providing ambulance services. Privately owned ambulance services staff and respond to medical emergencies in a given community as part of the 9-1-1 emergency response system. Regulations for acceptable response times, equipment, and other essential components of EMS systems are specified by contract. This allows the municipality oversight of the service provided, but it does not provide the service directly. As will be discussed, this "contracting-out" model has many benefits. Privatizing EMS services is a decision based not only on cost-savings, but on accountability. A thorough evaluation must be utilized in the selection process. Issues of efficiency, effectiveness, quality, customer service, responsiveness, and equity must be considered by the government, in addition to cost of service. The uncertain future of health care in the United States has led those in EMS to look beyond the field's internal market to explore additional opportunities for expanding and redefining its roles beyond emergency care. It is important, however, to consider how emergency medical care, the original role of EMS, can be best delivered. Responding to emergencies is not just one of the functions involved in this field, it is the principal function from which public perception of EMS is formed, and from which support for entering other markets can

    Many firms throughout Japan and around the world have come to realize that family planning is good for employee morale and company profits. Japanese and Indian efforts prove that family planning programs not only bring welfare benefits to workers, but commercial advantages to businesses. Because workers' family welfare is closely linked to labor welfare and productivity, the trade union movement has started to become active in promoting family planning activities. Factory-based family planning programs have often cut pregnancy rates in half. Godrej Enterprises of India started promoting family planning in 1957; it provides a model of how family planning has been incorporated into a comprehensive employee welfare system in a factory complex on the outskirts of Bombay, where about 1/2 the workers live in high-rise apartments in the company township of Pirojsha Nagar. Similar programs are presented in India, Thailand, Indonesia, Jamaica, Guatemala, Colombia, Korea, and Turkey. Limiting family size enriches workers' lives and improves the quality of the workforce. The International Labor Organization, through its Workers' Education Program on Population, has played an important role in stimulating industrial sector interest in family planning throughout the world.

    Drinking water for approximately one sixth of US households is obtained from private wells. These wells can become contaminated by pollutant chemicals or pathogenic organisms and cause illness. Although the US Environmental Protection Agency and all states offer guidance for construction, maintenance, and testing of private wells, there is little regulation. With few exceptions, well owners are responsible for their own wells. Children may also drink well water at child care or when traveling. Illness resulting from children's ingestion of contaminated water can be severe. This policy statement provides recommendations for inspection, testing, and remediation for wells providing drinking water for children.

Recommendations made by the 911 Commission included the incorporation of the private sector into future homeland security strategies. One such strategy is NYPD Shield. This programme is a nationally recognized award-winning public-private partnership dedicated to providing counterterrorism training and information sharing with government agencies, non-government organizations, private businesses, and the community. Information is shared through several platforms that include a dedicated website, instruction of counterterrorism training curricula, e-mail alerts, intelligence assessments and the hosting of quarterly conferences. This article also details how the NYPD Shield is providing its successful template to other law enforcement agencies enabling them to initiate similar programmes in their respective jurisdictions, and in doing so joining a National Shield Network.

  20. The HhH2/NDD domain of the Drosophila Nod chromokinesin-like protein is required for binding to chromosomes in the oocyte nucleus.

    Science.gov (United States)

    Cui, Wei; Hawley, R Scott

    2005-12-01

    Nod is a chromokinesin-like protein that plays a critical role in segregating achiasmate chromosomes during female meiosis. The C-terminal half of the Nod protein contains two putative DNA-binding domains. The first of these domains, known as the HMGN domain, consists of three tandemly repeated high-mobility group N motifs. This domain was previously shown to be both necessary and sufficient for binding of the C-terminal half of Nod to mitotic chromosomes in embryos. The second putative DNA-binding domain, denoted HhH(2)/NDD, is a helix-hairpin-helix(2)/Nod-like DNA-binding domain. Although the HhH(2)/NDD domain is not required or sufficient for chromosome binding in embryos, several well-characterized nod mutations have been mapped in this domain. To characterize the role of the HhH(2)/NDD domain in mediating Nod function, we created a series of UAS-driven transgene constructs capable of expressing either a wild-type Nod-GFP fusion protein or proteins in which the HhH(2)/NDD domain had been altered by site-directed mutagenesis. Although wild-type Nod-GFP localizes to the oocyte chromosomes and rescues the segregation defect in nod mutant oocytes, two of three proteins carrying mutants in the HhH(2)/NDD domain fail to either rescue the nod mutant phenotype or bind to oocyte chromosomes. However, these mutant proteins do bind to the polytene chromosomes in nurse-cell nuclei and enter the oocyte nucleus. Thus, even though the HhH(2)/NDD domain is not essential for chromosome binding in other cell types, it is required for chromosome binding in the oocyte. These HhH(2)/NDD mutants also block the localization of Nod to the posterior pole of stage 9-10A oocytes, a process that is thought to facilitate the interaction of Nod with the plus ends of microtubules (Cui et al. 2005). This observation suggests that the Nod HhH2/NDD domain may play other roles in addition to binding Nod to meiotic chromosomes.

  3. Behaviorism, private events, and the molar view of behavior.

    Science.gov (United States)

    Baum, William M

    2011-01-01

    Viewing the science of behavior (behavior analysis) to be a natural science, radical behaviorism rejects any form of dualism, including subjective-objective or inner-outer dualism. Yet radical behaviorists often claim that treating private events as covert behavior and internal stimuli is necessary and important to behavior analysis. To the contrary, this paper argues that, compared with the rejection of dualism, private events constitute a trivial idea and are irrelevant to accounts of behavior. Viewed in the framework of evolutionary theory or for any practical purpose, behavior is commerce with the environment. By its very nature, behavior is extended in time. The temptation to posit private events arises when an activity is viewed in too small a time frame, obscuring what the activity does. When activities are viewed in an appropriately extended time frame, private events become irrelevant to the account. This insight provides the answer to many philosophical questions about thinking, sensing, and feeling. Confusion about private events arises in large part from failure to appreciate fully the radical implications of replacing mentalistic ideas about language with the concept of verbal behavior. Like other operant behavior, verbal behavior involves no agent and no hidden causes; like all natural events, it is caused by other natural events. In a science of behavior grounded in evolutionary theory, the same set of principles applies to verbal and nonverbal behavior and to human and nonhuman organisms.

    2015-12-01

    Full Text Available In the present work, the effects of different casting parameters including pouring temperature and cooling rate on stainless steel structures and mechanical properties of heat resistant alloy (HH were studied. Mo nanoparticles were synthesized through sol-gel method and were coated on the stainless steel device using spin-coating method. The effect of coating layer on the device was studied by using XRD (X-Ray Diffraction and FT-IR (Fourier Transform Infra red and SEM (Scanning Electron Microscopy techniques. The obtained results indicated an enhancement of corrosion, surface abrasion protection without changing metal surface structure, and a reduction of leakage current through the stainless steel device. Furthermore, pouring temperature and cooling rate increase caused a fine grain structure to be acquired with less carbides and better distribution in the austenitic matrix.

  11. Public – private partnership : A critical discussion

    Directory of Open Access Journals (Sweden)

    Johans Tveit Sandvin

    2015-03-01

    Full Text Available Public-private partnerships have long been highly valued in Western welfare states, and the valuation of such cooperation has become even stronger in light of last year’s economic turbulence, particularly with voluntary non-profit organizations (VNPOs. At the same time, the voluntary sector is changing. The broad popular movements have generally declined in favour of more individual interests as the basis for forming VNPOs, and those organisations still involved in the provision of social services are becoming more and more similar to public service, due to requirements placed on them by the public sector. This is believed to have consequences for the value of such cooperation. If voluntary organisations in public services – or other private organisations for the matter – are becoming copies of public services, there is not much value to be gained from such cooperation, except for some financial gain.In this article, we argue that this conclusion is based on a rather narrow perception of public-voluntary cooperation. Research and debate on such cooperation are mainly preoccupied by what we call supplementary relations, in which voluntary organizations are assessed according to whether they can deliver cheaper or better services than the public sector. Based on an example of public-voluntary cooperation in preventive social work among young adults in Norway, the article show that public-voluntary collaboration can be truly valuable when it is based on a complimentary relation, in which parties collaborate because they command different resources equally important to the task at hand.

    2012-05-01

    Full Text Available This study is meant, first of all, to analyze the incriminations that the new Romanian Criminal Code sets for the protection of a person’s private life as a social value of maximum significance both for the human being and for any democratic society as a whole.There are two criminal offences treated in this study that are not to be found in the current criminal legislation: violation of private life and criminal trespassing of a legal person’s property. Likewise, the study will bring forth the novelties and the differences regarding the offences of criminal trespassing of a natural person’s property, disclosure of professional secret, violation of secret correspondence, illegal access to computerized system and illegal interception of electronic data transfer – acts that when, directly or indirectly, committed can cause harm to the intimacy of a person’s life.As an expression of the interdisciplinary nature of this subject, the study also sets out, as a subsidiary aspect, an evaluation of the circumstances under which the new criminal proceeding legislation allows public authorities to interfere with an individual’s private life. Thus, the emphasis is on the analysis of the circumstances under which special surveillance and investigation techniques can be used as evidence proceedings regulated by the new Romanian Criminal Procedure Code.

    2006-11-01

    Three new monocationic molecular hydrogen complexes of ruthenium of the type trans-[RuCl(2-H2)(PP)2][BF4] (PP = bis-1,2(diarylphosphino)ethane, aryl = -fluorobenzyl, benzyl, -methylbenzyl) have been prepared by protonating the precursor hydride complexes trans-[RuCl(H)(PP)2] using HBF4.Et2O. These three dihydrogen complexes are quite stable and have been isolated in the solid state. The intact nature of the H-H bond in these derivatives has been established from the short spin-lattice relaxation times (1, ) and the observation of substantial H, D couplings in the HD isotopomers. The H-H bond distances (HH, Å) increase from 0.97 to 1.01 Å as the electron donor ability of the diphosphine ligand increases from the -fluorobenzyl to the benzyl to the -methylbenzyl moiety. These dihydrogen complexes constitute the initial stages of elongation of the H-H bond enroute to its cleavage along the reaction coordinate for the oxidative addition of H2 to a metal centre.

    The DOE-RL is pursuing a new business strategy of hiring private contractors for treatment of Hanford Site tank wastes. This strategy is called `privatization` and includes design, permitting, construction, operation and deactivation of facilities for tank waste treatment. The TWRS Privatization Infrastructure Project consists of several sub-projects which will provide key services needed to support the privatization mission. This master site plan presently describes all pertinent aspects of the site and identifies all planned provisions for site development, utilities and other site services. It is a baseline document which will be revised as privatization proceeds through design, construction and start-up.

  6. Health care privatization in Latin America: comparing divergent privatization approaches in Chile, Colombia, and Mexico.

    Science.gov (United States)

    Bustamante, Arturo Vargas; Méndez, Claudio A

    2014-08-01

    The public-private mix in Chile, Colombia, and Mexico was very similar until the early 1980s when Chile undertook health care privatization as part of comprehensive health care reform. Since then, health care privatization policies have diverged in these countries. In this study we characterize health care privatization in Latin America and identify the main factors that promoted and hindered privatization by comparing the experiences of these countries. We argue that policy elites took advantage of specific policy environments and the diffusion of privatization policies to promote health care privatization while political mobilization against privatization, competing policy priorities, weak market and government institutions, and efforts to reach universal health insurance hindered privatization. The privatization approaches of Chile and Colombia were classified as "big-bang," since these countries implemented health care privatization more rapidly and with a wider scope compared with the case of Mexico, which was classified as gradualist, since the privatization path followed by this country adopted a slower pace and became more limited and focalized over time. We conclude that the emphasis on policy-driven privatization diminished in the 1990s and 2000s because of increased public health care financing and a shift in health care reform priorities. Health care privatization in the region, however, continued as a consequence of demand-driven privatization.

  7. Hh and Wnt signaling regulate formation of olig2+ neurons in the zebrafish cerebellum.

    McFarland, Karen A; Topczewska, Jolanta M; Weidinger, Gilbert; Dorsky, Richard I; Appel, Bruce

    2008-06-01

    The cerebellum, which forms from anterior hindbrain, coordinates motor movements and balance. Sensory input from the periphery is relayed and modulated by cerebellar interneurons, which are organized in layers. The mechanisms that specify the different neurons of the cerebellum and direct its layered organization remain poorly understood. Drawing from investigations of spinal cord, we hypothesized that the embryonic cerebellum is patterned on the dorsoventral axis by opposing morphogens. We tested this using zebrafish. Here we show that expression of olig2, which encodes a bHLH transcription factor, marks a distinct subset of neurons with similarities to eurydendroid neurons, the principal efferent neurons of the teleost cerebellum. In combination with other markers, olig2 reveals a dorsoventral organization of cerebellar neurons in embryos. Disruption of Hedgehog signaling, which patterns the ventral neural tube, produced a two-fold increase in the number of olig2(+) neurons. By contrast, olig2(+) neurons did not develop in embryos deficient for Wnt signaling, which patterns dorsal neural tube, nor did they develop in embryos deficient for both Hedgehog and Wnt signaling. Our data indicate that Hedgehog and Wnt work in opposition across the dorsoventral axis of the cerebellum to regulate formation of olig2(+) neurons. Specifically, we propose that Hedgehog limits the range of Wnt signaling, which is necessary for olig2(+) neuron development.

The leadership is perceived as a support pillar in maintaining any business. The analysis of this phenomenon is extremely extensive, starting with the culture of a company, the purpose of its existence and comprises aspects concerning the employees motivation and the degree of identifying themselves with the organizational objective.

The transactional method, manifested by the leader in the Romanian private banking system in Timişoara, seems to be the main phenomenon at the basis of their daily activity. The manager – leader hypothesis is slowly taking shape. Due to the resistance to change, generated by the educational model, from a managerial point of view, the balance is strongly tilting towards the managerial traits at the expense of the leadership ones. We are still at the stage where the tolerance towards liberty, uncertainty, are some of the traits of the leader in the Romanian private banking system in Timişoara, which are poorly identified at the management level of this very important segment of activity.

    López, R.; Acosta-Pulido, J. A.; Gómez, G.; Estalella, R.; Carrasco-González, C.

    2010-11-01

    Context. The dark cloud Lynds 723 (L723) is a low-mass star-forming region where one of the few known cases of a quadrupolar CO outflow has been reported. Two recent works have found that the radio continuum source VLA 2, towards the centre of the CO outflow, is actually a multiple system of young stellar objects (YSOs). Several line-emission nebulae that lie projected on the east-west CO outflow were detected in narrow-band Hα and [S ii] images. The spectra of the knots are characteristic of shock-excited gas (Herbig-Haro spectra), with supersonic blueshifted velocities, which suggests an optical outflow also powered by the VLA 2 YSO system of L723. Aims: Our aim is to study L723 in the near-infrared and look for line-emission nebulae associated with the optical and CO outflows. Methods: We imaged a field of ~5' × 5' centred on HH 223, which includes the whole region of the quadrupolar CO outflow with narrow-band filters centred on the [Fe ii] 1.644 μm and H2 2.122 μm lines, together with off-line Hc and Kc filters. The [Fe ii] and H2 line-emission structures were identified after extracting the continuum contribution, if any. Their positions were determined from an accurate astrometry of the images. Results: The H2 line-emission structures appear distributed over a region of 5.5 arcmin (~0.5 pc for a distance of 300 pc) at both sides of the VLA 2 YSO system, with an S-shape morphology, and are projected onto the east-west CO outflow. Most of them were resolved in smaller knotty substructures. The [Fe ii] emission only appears associated with HH 223. An additional nebular emission from the continuum in Hc and Kc appears associated with HH 223-K1, the structure closest to the VLA 2 YSO system, and could be tracing the cavity walls. Conclusions: We propose that the H2 structures form part of a large-scale near-infrared outflow, which is also associated with the VLA 2 YSO system. The current data do not allow us to discern which of the YSOs of VLA 2 is powering

However, it is not clear if the adoption of the BSC model is appropriate, or yet is hard to perceive how HEIs have modified and implemented this tool for evaluating educational institutions, public or privates, in Brazil. This study aims to fill the gap existent in the context of using the BSC in organizations. We intend to demonstrate how these organizations use performance indicators to measure their primary activities. A quantitative and exploratory study was developed from the analysis of performance indicators found in the web sites to Brazilian universities. A total of 91 Brazilian private universities evaluation process were reviewed. Even with a considerable amount of private HEIs there are few that have performance indicators guided by numerical and statistical data covering its main activities which is a concern for their managers in terms of managerial control.

    2016-06-01

    Full Text Available The role of private stakeholders in disaster operations goes far beyond the delivery of profits to its shareholders. Disasters and humanitarian operations literature acknowledges the importance of private sector in disaster lifecycle; however, it lacks an analysis of the risks and benefits of each different form of their engagement in such operations (contractual relationships, one-off relationships and CSR - Corporate Social Responsibility partnerships. To address this research gap, a literature review was conducted on papers covering the perspective of private stakeholders when engaging in disaster and humanitarian operations with stakeholders from public and social groups. The results revealed that some challenges are specific from one approach and others are common for all of them. Moreover, despite the increasing of reputation capital and organizational learning being used to motivate CSR approach, they are mentioned as benefits in approaches with lower engagement - contractual and one-off relationship approaches. Thus, the benefits and risks of each approach need to be carefully addressed by scholars and field professionals in order to seek better results from the engagement of private organizations.

  16. Privatization in the U. K

    Energy Technology Data Exchange (ETDEWEB)

    Polen, W.L.

    1989-09-01

    Under Margaret Thatcher's privatization initiative, the 65,000 MW system under the authority of the Central Electricity Generating Board (CEGB), the government owned generation and transmission company, will become three publicly held companies on January 1, 1990. National Power will receive 70% of CEGB's generating capacity including its nuclear assets. PowerGen will receive the remaining 30%. The National Grid Company will inherit CEGB's transmission assets. Barriers to entry for independent power producers are still evident, however. There is no standard contract for the purchase of power from independent producers. Furthermore, the purchase price for power is unknown and many developers feel it must rise from the current 5.4{cents}/kWh to 7.8{cents}/kWh for an adequate rate of return for private power producers. Finally, many British power experts told the trade mission they fear National Power and PowerGen, with their large generating capacities and economies of scale, may try to bar independent power producers from entering the market. They may do so by undercutting the price of independent power production and monopolizing the real estate for potential power projects in southern Britain.

  17. PRIVATE OR PUBLIC PENSION INSURANCE?

    Directory of Open Access Journals (Sweden)

    Bogomil Manov

    2013-03-01

    Full Text Available The most recent trends in population dynamics and increased longevity risk have provoked a rigorous debate whether the private or the public pension insurance system should be predominant. The public pension insurance is dominated by the state that guarantees its stability, but is often compared to a pyramid or a Ponzi scheme. The private pension insurance provides personal retirement accounts and proper ownership of the accumulated funds, but its sustainability during prolonged market crises and inadequate risk sharing are often questioned. In order to address the issue, this study analyzes and compares a large set of arguments and popular opinions in favour and against both pension models. As a result of the study, a conclusion is drawn stating that both types of pension insurance, despite of their positive and negative features have their essential role nowadays. This study is part of a growing set of articles on the feasibility of using a proper combination of the two pension models and will contribute to future research on the topic and might benefit policymakers in taking an appropriate decision.

  18. Two Component Decomposition of Dual Polarimetric HH/VV SAR Data: Case Study for the Tundra Environment of the Mackenzie Delta Region, Canada

    Directory of Open Access Journals (Sweden)

    Tobias Ullmann

    2016-12-01

    Full Text Available This study investigates a two component decomposition technique for HH/VV-polarized PolSAR (Polarimetric Synthetic Aperture Radar data. The approach is a straight forward adaption of the Yamaguchi decomposition and decomposes the data into two scattering contributions: surface and double bounce under the assumption of a negligible vegetation scattering component in Tundra environments. The dependencies between the features of this two and the classical three component Yamaguchi decomposition were investigated for Radarsat-2 (quad and TerraSAR-X (HH/VV data for the Mackenzie Delta Region, Canada. In situ data on land cover were used to derive the scattering characteristics and to analyze the correlation among the PolSAR features. The double bounce and surface scattering features of the two and three component scattering model (derived from pseudo-HH/VV- and quad-polarized data showed similar scattering characteristics and positively correlated-R2 values of 0.60 (double bounce and 0.88 (surface scattering were observed. The presence of volume scattering led to differences between the features and these were minimized for land cover classes of low vegetation height that showed little volume scattering contribution. In terms of separability, the quad-polarized Radarsat-2 data offered the best separation of the examined tundra land cover types and will be best suited for the classification. This is anticipated as it represents the largest feature space of all tested ones. However; the classes “wetland” and “bare ground” showed clear positions in the feature spaces of the C- and X-Band HH/VV-polarized data and an accurate classification of these land cover types is promising. Among the possible dual-polarization modes of Radarsat-2 the HH/VV was found to be the favorable mode for the characterization of the aforementioned tundra land cover classes due to the coherent acquisition and the preserved co-pol. phase. Contrary, HH/HV-polarized and VV

    Regulation is almost a synonym for public law. Government, relying on its sovereign powers, intervenes into freedom for the sake of social betterment. Reality less and less coincides with this traditional picture. Regulation is increasingly replaced by private or hybrid governance, i.e., by blends of private and public elements. Constitutional doctrine is not well prepared for the ensuing four-polar conflict. The four actors are government, the private regulator, its addressees, and the prote...

  3. Nursing organizational climates in public and private hospitals.

    2014-06-01

    Researchers study climate to gain an understanding of the psychological environment of organizations, especially in healthcare institutions. Climate is considered to be the set of recurring patterns of individual and group behaviour in an organization. There is evidence confirming a relationship between ethical climate within organizations and job satisfaction. The aim of this study is to describe organizational climate for nursing personnel in public and private hospitals and to confirm the relationships among the climate variables of such hospitals. A correlational study was carried out to measure the organizational climate of one public hospital and two private hospitals in Granada. The Work Environment Scale was used for data collection. The Work Environment Scale includes 10 scales, ranging from 0 to 9, which were used to evaluate social, demographic and organizational climate variables. In this study, 386 subjects were surveyed in three hospitals. A total of 87% of the participants were female and 16% were male. Most participants were nurses (65.6%), followed by nursing aides (20%), and technicians (14.4%). The results obtained reflected different patterns of organizational climate formation, based on hospital type (i.e. public or private) within the Spanish context. Most of the dimensions were below the midpoint of the scale. In conclusion, in public hospitals, there is a greater specialization and the organizational climate is more salient than in the private hospitals. In addition, in the public hospitals, the characteristics of the human resources and their management can have a significant impact on the perception of the climate, which gives greater importance to the organizational climate as decisive of the ethical climate. © The Author(s) 2013.

    2016-01-01

    We present ALMA Cycle 1 observations of the HH 46/47 molecular outflow using combined 12m array and 7m array observations. We use 13CO and C18O emission to correct for the 12CO optical depth, to accurately estimate the outflow mass, momentum and kinetic energy. Applying the optical depth correction increases the mass estimate by a factor of 14, the momentum by a factor of 6, and the kinetic energy by a factor of about 2. The new 13CO(1-0) and C18O(1-0) data also allow us to trace denser and slower outflow material than that traced by 12CO. These species are only detected within about 1~2 km/s from the cloud velocity. The cavity wall of the red lobe appears at very low velocities (~0.2 km/s). Combing the material traced only by 13CO and C18O, the measured total mass of the CO outflow is 1.4 Msun, the total momentum is 1.7 Msun km/s and the total energy is 4.7e43 erg, assuming Tex=15 K. The improved angular resolution and sensitivity in 12CO reveal more details of the outflow structure. Specifically, we find th...

  9. HH 666: Different kinematics from H{\\alpha} and [Fe II] emission provide a missing link between jets and outflows

    CERN Document Server

    Reiter, Megan; Kiminki, Megan M; Bally, John

    2015-01-01

    HH 666 is an externally irradiated protostellar outflow in the Carina Nebula for which we present new near-IR [Fe II] spectra obtained with the FIRE spectrograph at Magellan Observatory. Earlier H{\\alpha} and near-IR [Fe II] imaging revealed that the two emission lines trace substantially different morphologies in the inner ~40" of the outflow. H{\\alpha} traces a broad cocoon that surrounds the collimated [Fe II] jet that extends throughout the parent dust pillar. New spectra show that this discrepancy extends to their kinematics. Near-IR [Fe II] emission traces steady, fast velocities of +/- 200 km/s from the eastern and western limbs of the jet. We compare this to a previously published H{\\alpha} spectrum that reveals a Hubble-flow velocity structure near the jet-driving source. New, second-epoch HST/ACS H{\\alpha} images reveal the lateral spreading of the H{\\alpha} outflow lobe away from the jet axis. H{\\alpha} proper motions also indicate a sudden increase in the mass-loss rate ~1000 yr ago, while steady ...

  10. KK MC-hh: Resumed exact O (α2L ) EW corrections in a hadronic MC event generator

    Jadach, S.; Ward, B. F. L.; Was, Z. A.; Yost, S. A.

    2016-10-01

    We present an improvement of the Monte Carlo (MC) event generator Herwiri2, where we recall the latter MC was a prototype for the inclusion of CEEX resummed electroweak (EW) corrections in hadron-hadron scattering at high center of momentum system (cms) energies. In this improvement the new exact O (α2L ) resummed EW generator K K MC 4.22, featuring as it does the CEEX realization of resummation in the EW sector, is put in union with the Herwig parton shower environment. The Les Houches (LHE) format of the attendant output event file means that all other conventional parton shower environments are available to the would-be user of the resulting new MC. For this reason (and others—see the text) we henceforth refer to the new improvement of the Herwiri2 MC as K K MC -hh. Since this new MC features exact O (α ) pure weak corrections from the DIZET EW library and features the CEEX and the EEX YFS-style resummation of large multiple photon effects, it provides already the concrete path to 0.05% precision on such effects if we focus on the EW effects themselves. We therefore show predictions for observable distributions and comparisons with other approaches in the literature. This MC represents an important step in the realization of the exact amplitude-based QED ⊗QCD resummation paradigm. Independently of this latter observation, the MC rigorously quantifies important EW effects in the current LHC experiments.

    The inhomogeneous cascade-stochastic model of multiple hadrons production in inelastic p-bar p- and pp-interactions at high energies is proposed. In this model inclusive rapidity distributions of secondary hadrons are used as input data. One-parameter cascade-stochastic multiplicity distribution, where adjustable parameter has sense of the height of Feynman plateau of inclusive rapidity distribution of secondary hadrons in one hadron shower, is obtained. It is shown that all known now experimental data concerning both multiplicity and rapidity distributions of secondary particles in inelastic hh-processes in energy range s=30-1800 GeV, and also the ratio of cumulant moments to factorial moments of the multiplicity distributions in energy range s=200-900 GeV are described with high accuracy by one-parameter cascade-stochastic model of multiple hadrons production. The explicit form of asymptotic of distributions as well-known Polyakov-Dokshitzer's scaling function for quark and gluon jets is obtained by fitting of prognosis multiplicity distributions at energies s=14-30 TeV. A simplified quantitative analysis is presented and the qualitative explanation of behavior features of forward-backward multiplicity correlations is given within the framework of proposed model.

    'Water in Star-forming regions with Herschel' (WISH) is a Herschel Key Programme aimed at understanding the physical and chemical structure of young stellar objects (YSOs) with a focus on water and related species. The low-mass protostar HH 46 was observed with the Photodetector Array Camera and Spectrometer (PACS) on the Herschel Space Observatory to measure emission in H2O, CO, OH, [OI], and [CII] lines located between 63 and 186 um. The excitation and spatial distribution of emission can disentangle the different heating mechanisms of YSOs, with better spatial resolution and sensitivity than previously possible. Far-IR line emission is detected at the position of the protostar and along the outflow axis. The OH emission is concentrated at the central position, CO emission is bright at the central position and along the outflow, and H2O emission is concentrated in the outflow. In addition, [OI] emission is seen in low-velocity gas, assumed to be related to the envelope, and is also seen shifted up to 170 km...

    We investigate the plausibility of detecting X-ray emission from a stellar jet that impacts against a dense molecular cloud. This scenario may be usual for classical T Tauri stars with jets in dense star-forming complexes. We first model the impact of a jet against a dense cloud by 2D axisymmetric hydrodynamic simulations, exploring different configurations of the ambient environment. Then, we compare our results with XMM-Newton observations of the Herbig-Haro object HH 248, where extended X-ray emission aligned with the optical knots is detected at the edge of the nearby IC 434 cloud. Our simulations show that a jet can produce plasma with temperatures up to 10 MK, consistent with production of X-ray emission, after impacting a dense cloud. We find that jets denser than the ambient medium but less dense than the cloud produce detectable X-ray emission only at the impact onto the cloud. From the exploration of the model parameter space, we constrain the physical conditions (jet density and velocity, cloud den...

    2015-01-01

    Supernova (SN) 2002hh was unusual among core-collapse SNe because it was highly reddened, and displayed a bright infrared (IR) excess due to radiatively heated dust in its circumstellar medium (CSM). Estimates for the mass of dust responsible for the IR echo suggested the presence of a massive shell within 0.26 pc of the star. For a velocity of 5000 - 10000 km/s, this material should be hit by the SN blast wave at late times, starting at roughly 12 years post-explosion. We have obtained deep late-time spectra with the MMT Blue Channel spectrograph to search for any spectral signatures of ongoing shock interaction. Interaction with a strength comparable to SN 1987A's collision with the equatorial ring would be detected in our data. However, in the spectra reported here, we do not detect clear signs of strong CSM interaction, contrary to expectations based on the reported radii of the dust shell. We do, however, detect emission associated with the old SN, and we find that the broad lines in the spectrum indicat...

Estimates for the mass of dust responsible for the IR echo suggested the presence of a massive shell within 0.26 pc of the star. For a velocity of 5000-10 000 km s-1, this material should be hit by the SN blast wave at late times, starting at roughly 12 years post-explosion. We have obtained deep late-time spectra with the Multiple Mirror Telescope (MMT) Blue Channel spectrograph to search for any spectral signatures of ongoing shock interaction. Interaction with a strength comparable to SN 1987A's collision with the equatorial ring would be detected in our data. However, in the spectra reported here, we do not detect clear signs of strong CSM interaction, contrary to expectations based on the reported radii of the dust shell. We do, however, detect emission associated with the old SN, and we find that the broad lines in the spectrum indicate a continuation of an ongoing reflected light echo, which appears similar to the spectrum at peak luminosity for this Type II-P event.

    2010-01-01

    The dark cloud Lynds 723 (L723) is a low-mass star-forming region where one of the few known cases of a quadrupolar CO outflow has been reported. Two recent works have found that the radio continuum source VLA 2, towards the centre of the CO outflow, is actually a multiple system of young stellar objects (YSOs). Several line-emission nebulae that lie projected on the east-west CO outflow were detected in narrow-band Halpha and [SII] images. The spectra of the knots are characteristic of shock-excited gas (Herbig-Haro spectra), with supersonic blueshifted velocities, which suggests an optical outflow also powered by the VLA 2 YSO system of L723. We imaged a field of ~5' X 5' centred on HH 223, which includes the whole region of the quadrupolar CO outflow with nir narrow-band filters . The H2 line-emission structures appear distributed over a region of 5.5' (0.5 pc for a distance of 300 pc) at both sides of the VLA 2 YSO system, with an S-shape morphology, and are projected onto the east-west CO outflow.

    Higgs boson self-interactions can be investigated via di-Higgs (pp→hh+X) production at the LHC. With a small O(30) fb Standard Model production cross section, and a large tt{sup ¯} background, this measurement has been considered challenging, even at a luminosity-upgraded LHC. We demonstrate that by using simple kinematic bounding variables, of the sort already employed in existing LHC searches, the dominant tt{sup ¯} background can be largely eliminated. Simulations of the signal and the dominant background demonstrate the prospect for measurement of the di-Higgs production cross section at the 30% level using 3 ab{sup −1} of integrated luminosity at a high luminosity LHC. This corresponds to a Higgs self-coupling determination with 60% accuracy in the bb{sup ¯}τ{sup +}τ{sup −} mode, with potential for further improvements from e.g. subjet technologies and from additional di-Higgs decay channels.

    Plants that interact with pathogenic bacteria in their natural environments have developed barriers to block or contain the infection. Phytopathogenic bacteria have evolved mechanisms to subvert these defenses and promote infection. Thus, the type 3 secretion system (T3SS) delivers bacterial effectors directly into the plant cells to alter host signaling and suppress defenses, providing an appropriate environment for bacterial multiplication. Some rhizobial strains possess a symbiotic T3SS that seems to be involved in the suppression of host defenses to promote nodulation and determine the host range. In this work, we show that the inactivation of the Sinorhizobium (Ensifer) fredii HH103 T3SS negatively affects soybean nodulation in the early stages of the symbiotic process, which is associated with a reduction of the expression of early nodulation genes. This symbiotic phenotype could be the consequence of the bacterial triggering of soybean defense responses associated with the production of salicylic acid (SA) and the impairment of the T3SS mutant to suppress these responses. Interestingly, the early induction of the transcription of GmMPK4, which negatively regulates SA accumulation and defense responses in soybean via WRKY33, could be associated with the differential defense responses induced by the parental and the T3SS mutant strain.

    2015-09-01

    Full Text Available Multitemporal Phased Array type L-band Synthetic Aperture Radar (PALSAR horizontally transmitted and horizontally received (HH coherence data was decomposed into temporal-coherence, spatial-coherence, and thermal noise components. The multitemporal data spanned between February and May of 2008, and consisted of two pairs of interferometric SAR (InSAR images formed by consecutive repeat passes. With the analysis of ancillary data, a snow increase process and a snow decrease process were determined. Then, the multiple temporal-coherence components were used to study the variation of thawing and freezing statuses of snow because the components can mostly reflect the temporal change of the snow that occurred between two data acquisitions. Compared with snow mapping results derived from optical images, the outcomes from the snow increase process and the snow decrease process reached an overall accuracy of 71.3% and 79.5%, respectively. Being capable of delineating not only the areas with or without snow cover but also status changes among no-snow, wet snow, and dry snow, we have developed a critical means to assess the water resource in alpine areas.

Trajectory data carries rich information that is useful for many data analysis tasks. Yet, improper publishing and use of trajectory data could jeopardize individual privacy. However, it has been shown that existing privacy-preserving trajectory data publishing methods derived from partition-based privacy models, for example k-anonymity, are unable to provide sufficient privacy protection. In this paper, motivated by the data publishing scenario at the Societe de transport de Montreal (STM), the public transit agency in Montreal area, we study the problem of publishing trajectory data under the rigorous differential privacy model. We propose an efficient data-dependent yet differentially private sanitization algorithm, which is applicable to different types of trajectory data. The efficiency of our approach comes from adaptively narrowing down the output domain by building...
