The orbit and physical parameters of the previously unsolved double-lined eclipsing binary Tyc 5227-1023-1, discovered during the search for RR Lyr variable candidate members of the Aquarius stream, are derived using high-resolution chelle spectroscopy and V, i' photometry. A synthetic spectral analysis of both components has been performed, yielding metallicity [M/H] =-0.63± 0.11 for both stars a

The asymmetric formal hydroamination of enamines using a CuH catalyst is reported. The method provides a straightforward and efficient approach to the synthesis of chiral 1,2-dialkyl amines in good yields with high levels of enantioselectivities for a broad range of substrates, and should have significant value for the preparation of molecules bearing a 1,2-diamine motif.

The value of a statistical life (VSL) is a widely used measure for the value of mortality risk reduction. As VSL should reflect preferences and attitudes to risk, there are reasons to believe that it varies depending on the type of risk involved. It has been argued that cancer should be considered a "dread disease," which supports the use of a "cancer premium." The objective of this study is to in

Dysfunction of the gastrointestinal tract has now been recognized to affect all stages of Parkinson's disease (PD). The consequences lead to problems with absorption of oral medication, erratic treatment response, as well as silent aspiration, which is one of the key risk factors in developing pneumonia. The issue is further complicated by other gut abnormalities, such as small intestinal bacteria

Accurate measurement of bank risk is a matter of considerable importance for bank regulation and supervision. Current practices in most countries emphasize reliance on financial statement data for assessing banks’ risk. However, the possibility of increased reliance on market-based risk indicators has been a topic for academic and regulatory debate for a long time. Market monitoring of bank risk h

Hailed by economists as an idea whose time has come, the `new economic geography' has not been quite as favourably received by geographers. Frequently seen as a prime case of academic imperialism, few appear willing to concede that economists may have something to contribute to economic geography. Conversely, beyond the token reference to vintage publications, economistsoften dismiss geographers'

In the present study the inflammatory response was quantitatively evaluated during peripheral nerve regeneration. The fluid from silicone nerve regeneration chambers, inserted in rats, was collected during the early period of regeneration of transected sciatic nerves (6 h-7 d) and analysed with respect to inflammatory cells and mediators (leukotriene B4, LTB4, and interleukin-1 alpha, IL-1 alpha).

Plastics play an essential role in modern society, but also lead to significant impacts on the environment and climate. Reducing such impacts while retaining the usefulness of plastics requires a shift towards a more circular and sustainable plastics system. This report tells the story of plastics, and their effect on the environment and climate, and looks at their place in a European circular eco

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the effects of methylxanthine administration on the incidence of apnea and longer-term clinical outcomes in preterm infants including infants at risk for or having apnea and preterm infants peri-extubation.

In a recent paper we introduced the chirality-flow formalism, a method for simple and transparent calculations of Feynman diagrams based on the left- and right-chiral sl(2 , C) nature of spacetime. While our previous work focused on massless QED and QCD at tree-level, we here extend the chirality-flow formalism to the full (tree-level) Standard Model, including massive particles and electroweak in

It is well recognised that adolescents and young adults (AYA) with cancer have inequitable access to oncology services that provide expert cancer care and consider their unique needs. Subsequently, survival gains in this patient population have improved only modestly compared with older adults and children with cancer. In 2015, the European Society for Medical Oncology (ESMO) and the European Soci

Lung neuroendocrine neoplasms (NEN) are a heterogeneous population of neoplasms with different pathology, clinical behavior, and prognosis compared to the more common lung cancers. The diagnostic work-up and treatment of patients with lung- NEN has undergone major recent advances and new methods are currently being introduced into the clinic. These Nordic guidelines summarize and update the Nordic

Evidence supporting the benefits of exercise following the diagnosis of breast cancer is overwhelming and compelling. Exercise reduces the severity and number of treatment-related side effects, optimizes quality of life during and following treatment, and may optimize survival. Yet, exercise does not uniformly form part of the standards of care provided to women following a breast cancer diagnosis

Welding aerosols have been sampled in different size fractions using a moving stage cascade impactor. Sampling has been done for different welding methods and for varying welding parameters. The elemental composition of the different size fractions have been determined by Proton Induced X-ray Emission, PIXE, combined with a nuclear method for fluorine analysis. Results show maximum mass of most el

In strategic management, the concept of organizational capabilities appears in two sets of related literatures: the resource-based view and the dynamic capabilities approach. The resource-based view treats organizational capabilities as unitary factors that explain cross-sectional industry performance differentials. The dynamic capabilities approach, on the other hand, treats organizational capabi
