The fruits of the doum palm tree, Hyphaene thebaica are one of the oldest relish fruit. This study analyzed the chemical composition (both proximate and the mineral contents) of this plant, as well as its antioxidant property. The mineral content was determined by atomic absorption spectrophotometry, while the proximate and phytochemical analyses were carried out using standard procedures at Bayero University, Kano. The fruit were found to contain some minerals including K (3366.21 mg/100 g), Ca (292.04 mg/100 g), Na (212.27 mg/100 g), Mg (177.14 mg/100 g), Fe (4.86 mg/100 g), Mn (0.83 mg/100 g), Zn (0.68 mg/100 g), Cu (0.40 mg/100 g), Ni (0.32 mg/100 g) and Co (0.12 mg/100 g). The proximate composition of the doum palm fruit pulp reveals protein (2.86%), lipid (0.92%), ash content (6.24%), crude fiber (12.87%), moisture content (8.64%) and carbohydrate 68.47%. The DPPH radical scavenging efficacy of the ethanol extract of the fruit of the doum palm tree was analyzed at different concentrations of the extract. At concentration 0.0625 mg/mL, 0.125 mg/mL, 0.250 mg/mL and 0.500 mg/mL the extract showed inhibitory activity of 31%, 61%, 72% and 81% respectively. Thus the doum palm fruit pulp extract possess potential antioxidant properties.

Nanometer scale cells delaminated from oil palm fruit bunch (EFB) microfiber cell walls were coated on commercial A4 and laboratory sheets prepared from virgin fibers. High-resolution transmission electron microscopy (HRTEM) revealed the cells as translucent laminae of fibrils (TRX) bound together in a 5 nm to 100 nm thick web with dendritic edges. Coating of TRX onto the commercial A4 paper improved inkjet printability by up to 80%. The nano-enabled printability occurred as a summed effect of TRX forming (1) a canopy on or “loose-masking” of the protruding inorganic fillers, (2) capillary bridging of micro-voids formed by TRX fibrillary ends, (3) partial bridging of micro-gaps, (4) masking of the fiber surface, and (5) nano-grip arising from dendritic ends slipping into the micro-voids. The TRX-coated virgin pulp network revealed improved nano-enabled coverage by significantly reducing the stray and by print uniformity. The results provided an insight into the possibility of interfacing TRX with the paper surface for an improved inkjet print and economy through high-precision printing, also providing a pleasurable reading experience.

The Moment

ABSTRACT Knowing the maturation of the Acrocomia aculeata (macaw palm) fruit is decisive for harvest to be performed when the fruit has a higher content and quality of oil. There are different approaches to monitor maturation and they can be classified as destructive and non-destructive. Variables obtained by optical instruments have been used to determine maturation stage. The present study evaluated the relationship between the biological activity measured by the optical technique of biospeckle laser and firmness, measured in the Acrocomia aculeata fruit pulp between the 41st and 61st week after flowering. The biological activity was quantified by biospeckle images, while the fruit pulp firmness was determined by digital penetrometer. Correlations between variables were evaluated during maturation and in the senescence of fruits. According to the results, significant correlation between biological activity and firmness was found for both evaluated conditions, demonstrating that biospeckle laser can be an effective non-invasive indicator of Acrocomia aculeate fruit maturation assisting in the determination of the moment of harvest.

ABSTRACTThis paper models maximum entropy configurations of idealized gravitational ring systems. Such configurations are of interest because systems generally evolve toward an ultimate state of maximum randomness. For simplicity, attention is confined to ultimate states for which interparticle interactions are no longer of first order importance. The planets, in their orbits about the sun, are one example of such a ring system. The extent to which the present approximation yields insight into ring systems such as Saturn's is explored briefly.
