    The absolute configuration of (+)-1,5-dicarboxy-9,10-dihydro-9,10- ethenoanthracene (IV) was shown to be 9R,10R by chemical correlation with (-)-2,5-diacetoxy-7-carboxytriptycene (V) whose configuration was proved to be 1S,6R by X-ray analysis by the Bijvoet method combined with chemical correlation.application/pdfjournal articl

    The Use of Digital Content to improve upon the Teaching and Learning of Science in Basic Schools in Ghana

    The use of improvised materials and digital content would have the following advantages : students would be able to construct their own items and use them to explain basic electrolysis while the school waits for the materials to be provided. Teachers would be able to prepare for lessons more easily. The digital content would provide some information about improvisation in explaining concepts. It is also a boost for environmental education in the sense that the electrolytes used would have few problems regarding their disposal and students would already be used to the materials. Finally, the cost of education, especially in the rural areas would be kept low as low cost materials would be used when the school could not afford the equipment.号数表示に誤記あり。刊行後「21」を「20・21」に訂正。departmental bulletin pape
