A growth-chamber experiment was conducted to evaluate whether ethylenenediurea (EDU), a chemical shown to be protective against ozone pollution, could ameliorate foliar damage induced by ultraviolet-B (UV-B) radiation exposure in 'Roanoke' soybean (Glycine max L.), a UV-B-sensitive cultivar, and whether these effects could be discriminated using fluorescence (F) observations. The experiment had...

Based on the Spreadsheet Competency Framework for finance professionals, in the present paper we introduce the Edu-Edition of the Spreadsheet Competency Framework (E 2 SCF). We claim that building spreadsheet competences should start in education, as early as possible, and this process is a lot more effective if support arrives from expert teachers. The main feature of E 2 SCF is high mathabili...

Research on Educational Metaverse (Edu-Metaverse) has developed into an active research field. Based 310 academic papers published from 2004 to 2022, this study identifies contributors, scientific cooperations, and themes using bibliometrics, social network analysis, topic modeling, keyword analysis. Results suggest that Edu-Metaverse gained increasing attention in academia since 2019. Countrie...

Boron dipyrromethene dyes bearing nitro, amino, isocyanate and isothiocyanate functions were readily prepared under mild conditions. Various combinations allow to produce urea, diurea, thiourea, dithiourea in the 3, 4 and 5-substitution positions of the appended phenyl group. Condensation of the 3,4-substituted diamino derivative with 1,10-phenanthroline-5,6-dione and 6-formyl-2-methylpyridine ...

In songbirds, neurogenesis in the song control nucleus HVC is sensitive to the hormonal and social environment but the dynamics of this process is difficult to assess with a single exogenous marker of new neurons. We simultaneously used three independent markers to investigate HVC neurogenesis in male and female canaries. Males were castrated, implanted with testosterone and housed either alone...

1. The purpose of this paper is to describe the roadmap for work to be undertaken as part of the Feasibility Study for an OECD Assessment of Higher Education Learning Outcomes (AHELO). This roadmap was put together following the advice of experts that met on three occasions in 2007 to provide guidance for a strategy [see EDU(2007)8, EDU(2007)9 and EDU(2007)14]. Planning for the AHELO feasibilit...
