    A Multiple System of Radio Sources at the Core of the L723 Multipolar Outflow

    Full text link
    We present high angular resolution Very Large Array multi-epoch continuum observations at 3.6 cm and 7 mm towards the core of the L723 multipolar outflow revealing a multiple system of four radio sources suspected to be YSOs in a region of only ~4 arcsecs (1200 AU) in extent. The 3.6 cm observations show that the previously detected source VLA 2 contains a close (separation ~0.29 arcsecs or ~90 AU) radio binary, with components (A and B) along a position angle of ~150 degrees. The northern component (VLA 2A) of this binary system is also detected in the 7 mm observations, with a positive spectral index between 3.6 cm and 7 mm. In addition, the source VLA 2A is associated with extended emission along a position angle of ~115 degrees, that we interpret as outflowing shock-ionized gas that is exciting a system of HH objects with the same position angle. A third, weak 3.6 cm source, VLA 2C, that is detected also at 7 mm, is located ~0.7 arcsecs northeast of VLA 2A, and is possibly associated with the water maser emission in the region. The 7 mm observations reveal the presence of an additional source, VLA 2D, located ~3.5 arcsecs southeast of VLA 2A, and with a 1.35 mm counterpart. All these radio continuum sources have a positive spectral index, compatible with them being YSOs. We also propose that the high velocity CO emission observed in the region could be the superposition of multiple outflows (at least three independent bipolar outflows) excited by the YSOs located at the core, instead of the previous interpretations in terms of only one or two outflows.Comment: Accepted for publication in The Astrophysical Journal (2007 December 6

    Price Strategy, Market Orientation, and Business Performance in the Hotel Industry

    Get PDF
    This study seeks to study the relationship between market orientation and business performance and to evaluate the mediating effect of adopting a low-price strategy in this relationship in the hotel industry. A sample from the Spanish and Portuguese hotel industry is used. Results show that the effect of market orientation on business performance is positive and direct. On the other hand, the results do not confirm the mediating effect of a strategy based on low-price in the strength of this relationship. Moreover, results indicate that a price strategy based on low-price is negatively related to hotel business performance.info:eu-repo/semantics/publishedVersio

    On the use of area-averaged void fraction and local bubble chord length entropies as two- phase flow regime indicators

    Get PDF
    In this work, the use of the area-averaged void fraction and bubble chord length entropies is introduced as flow regime indicators in two-phase flow systems. The entropy provides quantitative information about the disorder in the area-averaged void fraction or bubble chord length distributions. The CPDF (cumulative probability distribution function) of void fractions and bubble chord lengths obtained by means of impedance meters and conductivity probes are used to calculate both entropies. Entropy values for 242 flow conditions in upward two-phase flows in 25.4 mm and 50.8 mm pipes have been calculated. The measured conditions cover ranges from 0.13 m/s to 5 m/s in the superficial liquid velocity jf and ranges from 0.01 m/s to 25 m/s in the superficial gas velocity jg. The physical meaning of both entropies has been interpreted using the visual flow regime map information. The area-averaged void fraction and bubble chord length entropies capability as flow regime indicators have been checked with other statistical parameters and also with different input signals durations. The area-averaged void fraction and the bubble chord length entropies provide better or at least similar results than those obtained with other indicators that include more than one parameter. The entropy is capable to reduce the relevant information of the flow regimes in only one significant and useful parameter. In addition, the entropy computation time is shorter than the majority of the other indicators. The use of one parameter as input also represents faster predictions

    Home built environment interventions and inflammation biomarkers: a systematic review and meta-analysis protocol

    Get PDF
    BACKGROUND: Inflammation control is a fundamental part of chronic care in patients with a history of cancer and comorbidity. As the risk-benefit profile of anti-inflammatory drugs in cancer survivors (CS) is unclear, GPs and patients could benefit from alternative non-pharmacological treatment options for dysregulated inflammation. There is a potential for home built environment (H-BE) interventions to modulate inflammation, however, discrepancies exist between studies. AIM: To evaluate the effectiveness of H-BE interventions on cancer-associated inflammation biomarkers. DESIGN & SETTING: A systematic review and meta-analysis of randomised and non-randomised trials in community-dwelling adults. METHOD: PubMed-Medline, Embase, Web of Science, and Google Scholar will be searched for clinical trials published in January 2000 onwards. We will include H-BE interventions modifying air quality, thermal comfort, non-ionising radiation, noise, nature and water. No restrictions to study population will be applied to allow deriving expectations for effects of the interventions in CS from available source populations. Outcome measures will be inflammatory biomarkers clinically and physiologically relevant to cancer. The first reviewer will independently screen articles together with GPs and extract data that will be verified by a second reviewer. The quality of studies will be assessed using the Cochrane Risk-of-Bias tools. Depending on the clinical and methodological homogeneity of populations, interventions, and outcomes, we will conduct a meta-analysis using random-effects models. CONCLUSIONS: Findings will determine the effectiveness of H-BE interventions on inflammatory parameters, guide future directions for its provision in community-dwelling CS and support GPs with safer anti-inflammatory treatment options in high-risk patients for clinical complications

    Kinematics of Current Region Fragmentation in Semi-Inclusive Deeply Inelastic Scattering

    Get PDF
    Different kinematical regions of semi-inclusive deeply inelastic scattering (SIDIS) processes correspond to different underlying partonic pictures, and it is important to understand the transition between them. We find criteria in semi-inclusive deeply inelastic scattering (SIDIS) for identifying the current fragmentation region-the kinematical region where a factorization picture with fragmentation functions is appropriate, especially for studies of transverse-momentum-dependent (TMD) functions. This region is distinguished from the central (soft) and target fragmentation regions. The basis of our argument is in the errors in approximations used in deriving factorization. As compared with previous work, we show that it is essential to take account of the transverse momentum of the detected hadron, and we find a much more restricted range for genuine current fragmentation. We show that it is important to develop an extended factorization formulation to treat hadronization in the central region, as well as the current and target fragmentation regions, and to obtain a unified formalism spanning all rapidities for the detected hadron
