  • Journal of a Tour through North Wales and Part of Shropshire with Observations in Mineralogy and Other Branches of Natural History
    Arthur Aikin
    Journal of a Tour through North Wales was Aikin’s first book, published in 1797, when he was only 24 years old. It is based on a tour undertaken two years earlier, inspired by Horace Bénédict de Saussure’s Voyages dans les Alpes. Like other contemporaries who visited the region, he stopped at well-known destinations-Bala, Llanrwst, Beddgelert, Dolgellau, Anglesey, Llandudno, Ab...

  • Bioactive Nonpolar Metabolites from Native Plants of Argentina
    Andrea Mabel Sosa / Elena Cartagena / Ricardo Federico Laime
    Insects are one of the main pests of stored grains and their by-products. The need to control them until their total elimination leads to an incorrect use of chemical insecticides. An ecologically safer alternative is the application of secondary plant metabolites for their control. The authors studied the repellent and/or insecticidal activity of low polarity metabolites isola...
