    Effect of the annealing treatments on the transport and electroluminescence properties of SiO2 layers doped with Er and Si nanoclusters

    We studied the effect of RTP and furnace annealing on the transport properties and electroluminescence of Si-nc embedded in SiO2 layers, and of Er ions coupled to Si-nc. The light emitting devices have been fabri...

    Comparative effects of Glomus mosseae and P fertilizer on foliar mineral composition of Acacia senegal seedlings inoculated with Rhizobium

    A factorial experiment with two controlled factors was conducted in the greenhouse with Acacia Senegal seedlings. The substrate was a degraded sandy soil (Dior soil) poor in available P (11 ppm — Olsen). The firs...

    Vegetative propagation studies of gum arabic trees. 1. Propagation of Acacia senegal (L.) Willd. using lignified cuttings of small diameter with eight nodes

    In order to study and monitor rates of rooting, callusing and survival, small diameter stem cuttings (less than 0.4 cm) with eight nodes (12–14 cm long) were taken from trees in the field at different times of...
