Their carcasses were quickly buried at the DTRI facility that has since been concealed from public view with large tarpaulins.
Animals are usually put down by lethal injection, a method that will be more costly for DTRI, said its deputy director Amado Angeles.
As single gunshots were fired, Angeles, in a chance interview outside DTRI facility, said the process was carried out by 'expert marksmen' under the supervision of animal and science experts.
"More than 90 experts from different countries discussed the current issues and also exchanged expertise with their Saudi counterparts," said Ibrahim Al-Tisan, director general of Desalination Technologies Research Institute (DTRI
The control group presented the highest stress value in the right distal implant (loaded; 62.41 MPa), whereas the regular implants group presented a slight decrease (-0.5%) and the DTRI (-27.2%) and wide implants (-41.2%) groups had larger reductions in stress values.
However, both arrangements (parallel and tilted implants) with 3 implants of regular diameter presented an increase in stress values, except for the right distal screw (loaded) in the DTRI group.
The DTRI group presented the lowest and the regular implants group the highest value of stress.
