Seed was collected from a sweetgum tree in Washington County, Miss., in the fall of 1964 and stored at 35° to 40° F. for 4 months. Prior to sowing, the seed was stratified moist for 30 days at the same temperature. About 4 inches of loose silt loam was placed in 4inch clay pots. The soil was settled by sprinkling lightly with water and then leveled. Fifty seeds were placed in each pot and cover...

Appropriate curing of concrete is necessary to obtain maximum durability and achieve designed strength for exposed different environmental conditions. Curing regarded as the means regulating degree extent loss moisture from when cement in undergoing hydration. This study made a comparative consequence adopting methods on compressive modified with Palm Kernel Shell (PKS) aggregate. Concrete cube...

according to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. the low value residual gold ions existed in acid leaching tail solution in mouteh gold mine in iran with fellow heavy metals as pollutants (fe2+, cu2+, and zn2+). preparation of nano gold particles is achieved by two steps: first, by addition of ammonia as separatio...

recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. at the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver int...

Introduction The organizers of the European Molecular Biology Organization Workshop on Genomic Imprinting chose a truly trans-kingdom selection of speakers; there was a strong representation of those working in plants and mammals, with a sprinkling of those studying flies and worms. This organismal diversity was layered further with talks on topics ranging from germ cells, genomic imprinting an...

However, the conventional gold recovery process is cyanidation, due to the recent environmental laws; researchers are looking for alternative methods for the recovery of gold. Furthermore, the copper anode slime is one of the most important secondary sources of gold (about 1200 ppm). So, the main objective of the current work is gold separation from copper anode slime as a rich secondary source...
