WebOct 8, 2024 · Strain and Sprain Severity Grades. There are different grades of muscle strains, ranging from grade I to grade III. 1. Grade I muscle strains indicate that the muscle tissue is simply overstretched. Grade II muscle strains occur when the muscle tissue is partially torn. Grade III strains are full-thickness tears through the muscle tissue. WebJul 21, 1993 · The host crystals are of CsNiCl 3 type which exhibit a linear chain structure. These hosts incorporate trivalent rare earth ions such as Er 3+ to form a M 3+ -vacancy-M 3+ pair center. When both ions in an Er 3+ -vacancy-Er 3+ center are simultaneously excited an efficient energy transfer occurs between Er 3+ ions.
