Cold Storage and Cold Rooms from Compressed Air

Ergonomic analysis in cold storage rooms: a study of case.

The human work possess a history and, in this dimension, the man is submitted to the conditions that confer it physical and psychological consequences. The activity of work in the present time imposes adverse labor conditions. The ergonomics is a science that it aims at to study the real activity of the work with sights its transformation. This study it was carried through in a sector of proces...

Crystal structure of cold compressed graphite.

Through a systematic structural search we found an allotrope of carbon with Cmmm symmetry which we predict to be more stable than graphite for pressures above 10 GPa. This material, which we refer to as Z-carbon, is formed by pure sp(3) bonds and it provides an explanation to several features in experimental x-ray diffraction and Raman spectra of graphite under pressure. The transition from gra...
