Soil legacy data rescue via GlobalSoilMap and other international and national initiatives The International Center for Tropical Agriculture (CIAT) believes that open access contributes to its mission of reducing hunger and poverty, and improving human nutrition in the tropics through research aimed at increasing the eco-efficiency of agriculture. CIAT is committed to creating and sharing knowledge and information openly and globally. We do this through collaborative research as well as through the open sharing of our data, tools, and publications.

Abstract. Triorganoboranes BR 3 , Et-9-BBN, BPh 3 , and B(C 6 F 5 ) 3 , were compared in their reactivity towards various dialkynyl(diorgano)tin. 1,1-Carboboration took place readily in two consecutive steps (inter-and intramolecular), leading either to stannoles or to 1,4-stannabora-cyclohexa-2,5-dienes, or mixtures thereof. The weakest Lewis-acidic triorganoboranes BEt 3 and Et-9-BBN afford selectively stannoles with

The triorganoboranes BEt 3 , BPh 3 , and B(C 6 F 5 ) 3 were allowed to react with bis(trimethylsilylethynyl)diorganotin com-n Oct (c), Ph (d)] to give selectively and quantitatively stannoles. The reactions proceeded by 1,1-carboboration in two consecutive steps (inter-and intramolecular) and intermediates were detected by NMR spectroscopy. In one case, using the strongly electrophilic B(C 6 F 5 ) 3 , a zwitterionic inter-

The English for Academic Purposes (EAP) Toolkit provides a wide range of online learning resources which are used in a mixture of self-study, blended, and classroom settings, primarily by students whose first language is not English. The Toolkit was developed by the eLanguages team at the University of Southampton and first licensed in 2004. This paper describes the most recent major refreshment project to improve both the functionality and appearance of the Toolkit. With the latest updates, we have aimed to increase the appeal of the resources to encourage greater autonomous usage by students, and to improve the ease with which staff can recommend and use Toolkit resources with their students. In this paper we introduce the key updates to the resources, including new functionalities and features, expanding the Toolkit with additional learning resources, a new visual approach, responsive feedback, accessibility upgrades, and strategies for increasing student usage.
