This study was carried out in 2011 to investigate the suitability of date palm midribs (Phoenix dactelifera L.) as a lignocellulosic material for the production of wood-cement composite panels, in addition to enhancement their compatibility with cement using various pretreatments and chemical additives. Materials used for this study were midribs of fronds of different date palm varieties availa...

Natural agricultural products have the potential to be a substitute for synthetic polymers absorbentsin environmental remediation and spill cleanup recovery. One of these natural by-productswhich is available in many regions world Date Palm Fibers (DPF). DPF (also known assurface fibers) sorbent that exhibits good sorption characteristics. In an attempt tovalorize this abundant, low cost byprod...

Seed predators can limit plant recruitment and thus profoundly impinge the dynamics of plant populations, especially when diverse seed predators (e.g., native and introduced) attack particular plant populations. Surprisingly, however, we know little concerning the potential hierarchy of spatial scales (e.g., region, population, patch) and coupled ecological correlates governing variation in the...
