Optimizing the removal of fluoride from water using new carbons obtained by modification of nut shell with a calcium solution from egg shell
Carbons loaded with specific chemical moieties were prepared from pecan nut shells employing a natural modifier agent obtained from egg shell; which is rich in calcium; for the selective adsorption of fluoride from water. A L4 orthogonal array of the Taguchi method was used to optimize the synthesis conditions for obtaining these selective carbons. The […]
The regeneration of Brazil nut trees in relation to nut harvest intensity in the Trombetas River valley of Northern Amazonia; Brazil
This study examined the harvest of nuts from Brazil nut trees (Bertholletia excelsa) in the valley of the Trombetas River; a 760-km tributary on the northern bank of the Amazon River in Pará state; Brazil. The region is characterised by old-growth forests dominated by Brazil nut trees. Demographic data were obtained from twenty-five 50-m à […]
Spatial dynamics of cone production in Mediterranean climates: A case study of Pinus pinea L. in Portugal
Seed production of trees is key to natural regeneration of forests and to successful conservation management. Despite its importance no spatially explicit analyses of seed production have so far been carried out in this important field. Analyses like these are particularly important in areas with regular summer droughts. We used Pinus pinea L. as a […]
Maintaining the quality of unripe; fresh hazelnuts through storage under modified atmospheres.
Unripe hazelnuts are used for fresh consumption due to their delicate taste; the tenderness of the kernel and the fact that they are easy to shell manually without having to use tools. This report focuses on the possibility of storing unripe; fresh hazelnuts (Corylus avellana L.; cv. Tonda Gentile Romana) under modified atmospheres; with the […]
Development of a system to produce maps of agricultural profit on a continental scale: An example for Australia
Policy makers in the agricultural sector are confronted with challenges which might drive land use change and ultimately agricultural profitability to a substantial degree. The challenges include questions around climate variability; demographic changes; use of land for bio-fuel production and ensuring an increase in food production. As profitability triggers many agri-business decisions; knowledge about the […]
Survival of Salmonella Enteritidis PT 30 on inoculated almond kernels in hot water treatments.
Almonds are blanched by exposure to hot water or steam-injected water to remove the pellicle (skin) from the kernel. This study evaluated the survival of Salmonella Enteritidis PT 30; Salmonella Senftenberg 775 W and Enterococcus faecalis on whole raw almond kernels exposed to hot water. Whole; inoculated (7 to 9 log CFU/g) Nonpareil almonds (40 […]
