Bonifacio, C., CA Cunha, A. Muller, C. G. Timoteo, JM Dias, I. Moura, and MJ Romao. "Crystallization and preliminary X-ray diffraction analysis of the di-haem cytochrome c peroxidase from Pseudomonas stutzeri." Acta crystallographica. 59 (2003): 345-7. AbstractWebsite

Crystals of cytochrome c peroxidase from Pseudomonas stutzeri were obtained using sodium citrate and PEG 8000 as precipitants. A complete data set was collected to a resolution of 1.6 A under cryogenic conditions using synchrotron radiation at the ESRF. The crystals belong to space group P2(1), with unit-cell parameters a = 69.29, b = 143.31, c = 76.83 A, beta = 100.78 degrees. Four CCP molecules were found in the asymmetric unit, corresponding to a pair of dimers related by local dyads. The crystal packing in the structure shows that the functional dimers can dimerize, as suggested by previous biochemical studies.

Proceedings of the 9th International Conference EPMESC IX. Eds. V. P. Iu, L. N. Lamas, Y. - P. Li, and K. M. Mok. Macao, China: A.A.Balkema Publishers, 2003. 843-849. Abstract

The present study reports low velocity impact tests on composite laminate plates reinforced either with Kevlar 29 or Dyneema. The tests are produced using a Rosand Precision Impact tester. The experimental results obtained for Kevlar 29 are simulated numerically. The deflection history and the peak of the impact force are compared with experimental data and used to calibrate the numerical model.

Silva, M. A. G., C. Cismaşiu, and C. G. Chiorean. "Ballistic Simulation of Impact on Composite Laminates." Proceedings of the International Conference Constructions 2003. Vol. 2. Cluj-Napoca, Romania: The Technical University of Cluj-Napoca, 2003. 139-146. Abstract

The paper reports on numerical simulation of impact problems on fiber reinforced plastic composite laminated plates reinforced with Kevlar 29. The ballistic impact caused by STANAG-2920 projectile is analyzed to obtain an estimate for the V50 and the global damage. All estimate have been carried out using the finite difference numerical code AUTODYN-3D, are compared with the experimental data to illustrate the performance of the simulation. Good correlation between resulting simulations and experimental results is demonstrated both in terms of deformation and damage of the laminates and ballistic performance.
