analysis of genetic diversity in germplasm collections can facilitate reliable classification of accessions as well as identification of subsets of core accessions with possible utility for specific breeding purposes. to investigate the pattern of genetic variation in tall fescue (festuca arundinacea schreb) germplasm, a field experiment was accordingly conducted. seeds of 25 iranian, 11 hungar...

The validity of an accelerometric system (Myotest©) for assessing vertical jump height, vertical force and power, leg stiffness and reactivity index was examined. 20 healthy males performed 3×"5 hops in place", 3×"1 squat jump" and 3× "1 countermovement jump" during 2 test-retest sessions. The variables were simultaneously assessed using an accelerometer and a force platform at a frequency of 0...

conclusions the bleaching procedures using 20% carbamide peroxide and 45% carbamide peroxide and diode laser significantly decreased shear bond strength of brackets to the teeth. 45% carbamide peroxide had a more significant effect on bond strength compared to 20% carbamide peroxide. the difference in bond strength was not significant between laser group and either carbamide peroxide groups. re...

This work reports the level and ecotoxicity impact of metals in sediments Mallorquín swamp, a protected coastal lagoon Caribbean coast Colombia. The distribution was following decreasing order: Zn > Cu Pb Cd Hg, showing statistically significant differences among sites. average concentrations were about 17 5 times higher, respectively, compared to those background values. Several contamination ...

Concentrations of cefuzoname in cerebrospinal fluid (CSF) were determined in a total of 16 rabbits, 5 with healthy meninges, 5 with Staphylococcus aureus meningitis, and 6 with Escherichia coli meningitis. Mean percentages of the maximum concentration of the drug in CSF versus that in serum were 0.57, 3.37, and 4.40% for healthy rabbits, those with staphylococcal meningitis, and those with E. c...
