We present precision measurements of the 3 He + 4 He → 7 Be reaction in the range Ec.m. = 0.33 to 1.23 MeV using a small gas cell and detection of both prompt γ rays and 7 Be activity. Our prompt and activity measurements are in good agreement within the experimental uncertainty of several percent. We find S(0) = 0.595 ± 0.018 keV b from fits of the Kajino theory to our data. We compare our res...

In both the Sun and the early universe, the He(α,γ)Be reaction plays a key role. The rate of this reaction is the least certain nuclear input needed to calculate both the primordial Li abundance in big bang nucleosynthesis (BBN) and the solar neutrino flux. Taking advantage of several recent highly precise experiments, we analyse modern He(α,γ)Be data using a robust and minimally model dependen...

We study the impact of non-Abelian T-duality transformations on a string based cosmological model. The implementation of the pre-big-bang scenario is investigated. We found a region of the dual phase where such a picture is possible. e-mail: [email protected] e-mail: [email protected] CNRS UPRES-A 6083

range of activities, including investigating alleged incidents of abuse and neglect, protecting victimized children, supporting and preserving families, and assisting children who must be temporarily or permanently removed from their parents’ homes. Child welfare agencies are an integral part of the public social services safety net. They often act as the provider of last resort since state law...

Using social justice as the conceptual foundation, the authors present the structural barriers to socially just intercountry adoptions (ICAs) that can exploit and oppress vulnerable children and families participating in ICAs. They argue that such practices threaten the integrity of social work practice in that arena and the survival of ICA as a placement option. Government structures, disparit...

The adoption of the principles of sustainable development (SD) is increasingly seen as an important way to align the strategic plan of organizations with the specific objectives and procedures used for project execution. However, more research is still needed to identify how SD contributes to align the strategic plan of clients of the building sector with their short-term needs of construction ...

Healthier lifestyles may contribute to prevent overweight in adolescents. Although school-based interventions show promising results, adoption and implementation by secondary schools and involvement of parents is difficult. Our study aims to gain a better understanding of the problem awareness and beliefs of school staff and parents regarding adolescents' overweight and energy balance-related b...

social responsibility has been recognized as one of the most important elements in the existence and survival of the organizations. therefore, studying and investigating this fundamental element considering social identity leads not only into enhancing organizational commitment, but also increasing the sense of satisfaction among stakeholders outside the organization. the present research inves...

This paper is concerned with exploring the relationship between perceptions of professional identities, interprofessional education (IPE) and collaborative practice. It seeks to introduce the concept of interprofessional responsibility as both a shift in the way in which to conceptualise the professional identity of Health and Social Care (H&SC) staff and as a new set of practices that help to ...
