Neutron diffraction provides a direct probe for the ordering of spins from unpaired electrons in materials with magnetic properties. The ordering of the spins can be modeled in many cases by adding spin directions to standard crystallographic models. This requires, however, that crystallographic space groups be extended by addition of a “color” attribute to symmetry operations, which determines...

The Mediterranean Sea has a long-lasting history of fishery exploitation that, together with other anthropogenic impacts, led to declines in several marine organisms. In particular, elasmobranch populations have been severely impacted, drastic decreases abundance and species diversity. Based on their experience, fishers can provide information occurrence, behavioural traits long-term scale, the...

E-noses that combine machine learning and gas sensor arrays (GSAs) are widely used for the detection identification of various gases. GSAs produce signals provide vital information about exposed gases algorithms, rendering them indispensable within smart-gas sensing arena. In this work, we present a detailed assessment several techniques employed estimation their concentrations. The modeling pr...

Gay-Straight Alliances (GSAs) are student-led, school-based clubs that aim to provide a safe environment in the school context for lesbian, gay, bisexual, and transgender (LGBT) students, as well as their straight allies. The present study examines the potential for GSAs to support positive youth development and to reduce associations among LGBT-specific school victimization and negative young ...

In the field of positive youth development programs, "empowerment" is used interchangeably with youth activism, leadership, civic participation and self-efficacy. However, few studies have captured what empowerment means to young people in diverse contexts. This article explores how youth define and experience empowerment in youth-led organizations characterized by social justice goals: high sc...

This paper introduces the special effects of the new developed Regional Satellite Augmentation System (RSAS) as an integration component of the Global Satellite Augmentation System (GSAS) employing current and new Satellite Communications, Navigation and Surveillance (CNS) for improving Air Traffic Control (ATC) and Air Traffic Management and of GPS or GLONASS and enhancement of safety and emer...

Objective Surrogacy is one of the most challenging infertility treatments engaging ethical, psychological and social issues. Attitudes survey plays an important role to disclosure variant aspects of surrogacy, to help meeting legislative gaps and ambiguities, and to convert controversial dimensions surrounding surrogacy to a normative concept that eliminates stigma. The aim of this study is to ...

where the peak shapes were described by a pseudo-Voigt function and the background was modeled with an 6-term polynomial. Additionally, the PXRD patterns obtained at room temperature and 100 K were analyzed by Le Bail refinement using the GSAS and EXPGUI software, 2,3 where the peak shapes were described by a pseudo-Voigt function (CW profile function 3) and the background was modeled with an 4...
