Calcium phosphate with hydroxyapatite structure was synthesized and its ability to adsorb Cr(VI) from aqueous solution is presented. XRD, BET, IR, TGA, SEM and EDS techniques were used to characterize the obtained material. Apure phase was obtained through a simple…

In situ selection of vineyard peach (Prunus pérsica spp. vulgaris Mill.) genotypes was conducted in 2006 and 2007 in the region of Kfusevac (Central Serbia). Identification, observation and recording of the phenological and pomological properties of the highest-quality genotypes were…

Aromatic rices (Oryza sativa L.) normally produce enormous spikelets of low grain weight resulting low yield. Grain weight and grain density are the vital indicators of grain filling and mainly dependent on genetic make-up. Detail study of grain density and…

Using "speech act" theory as its starting point, the article ponders the sources of hostility and conflict in global politics, arguing that discourse as a social practice is an increasingly crucial but a more or less neglected source of (in)security…

Inappropriate soil management practices that have been applied in the Yafacuy River basin, Venezuela, have led to the loss of soil organic matter and crop productivity. The incorporation of composted organic residues has been suggested as an alternative management practice…
