The LKB enclosure and associated structures at Menneville Derrière le Village (Aisne, France): from diversity in mortuary behaviour to a coherent system

open access: yesGallia Préhistoire, 2016
The enclosure of Menneville consists of segments of ditches stretching over nearly 1000 m and enclosing a large LBK settlement with at least two phases of occupation dated to the middle and late stages of the later LBK of the Paris Basin, or RRBP (Rubané

Citrus Production Under Screen as a Strategy to Protect Grapefruit Trees From Huanglongbing Disease

open access: yesFrontiers in Plant Science, 2019
Citrus production under enclosed structures can exclude the Asian citrus psyllid (ACP, Diaphorina citri) and eliminate the negative effects of citrus greening or huanglongbing (HLB) disease caused by Candidatus Liberibacter asiaticus to the grapefruit ...
