Proliferation control is achieved solely in this model by a feedback, which changes the flow of cells from the g0 state into the g1 phase according to the amount of the DNA synthesizing S phase cells. Behavior of the model was compared with experimental data available about the CFUs (colony-forming units — spleen) cell population. A reasonable agreement between simulation results and experimental data could be obtained provided that some cells do not pass through the G0 state during their cell cycle. Necessity to establish the seeding efficiency of the spleen colony technique arose when experimental CFUs data showing pluripotential stem cells response to hydroxyurea damage were compared with results obtained from the model.Notes: Zusammenfassung Es wird ein Computer-Modell für die Stammzellpopulation vorgestellt. Die Proliferationskontrolle wird in diesem Modell nur durch eine Rückkopplung erreicht, die den Zellfluß von der G0- in die G1-Phase aufgrund der Anzahl der S-Phase-Zellen, die DNA synthetisieren, ändert. Das Verhalten des Modells wurde mit experimentellen Daten verglichen, die aus der Analyse der CFUs-Zellpopulation stammen. Es besteht eine brauchbare Übereinstimmung zwischen den errechneten und experimentellen Daten, vorausgesetzt, daß einzelne Zellen während ihres Zellzyklus die G0-Phase nicht passieren. Wenn die experimentellen CFUs-Daten von pluripotenten Stammzellen nach einer Hydroxyharnstoff-Schädigung mit den Ergebnissen des Modells verglichen werden, besteht die Notwendigkeit, die Angehrate der Milzkolonietechnik zu bestimmen.Type of Medium: Electronic ResourceURL: -

ISSN: 1741-2765Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract A brief summary is presented on the current status of knowledge regarding the dynamic behavior of crystalline materials in terms of athermal, thermally activated, viscous damping, and relativistic motion of dislocations. It is shown that dislocation concepts have contributed substantially to a better and more unified rationalization of the dynamic behavior of crystalline materials than heretofore possible. Particular emphasis is given to the need for a more complete theoretical understanding of dislocation mechanics. Also, the requirements for more detailed and better experiments are expressed particularly for dislocation-velocity determinations in the viscous damping and relativistic ranges of conditions.Type of Medium: Electronic ResourceURL: -

ISSN: 1741-2765Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract In conventional fracture-toughness testing, the line of application of the loads remains fixed with respect to specimen geometry. In this testing machine, the load moves with the advancing crack front, and displacement is used as the controlled variable to propagate and arrest a crack. The energy-release rate at the onset of crack propagation and, hence, the plane-strain fracture toughnessK Ic can be measured directly without compliance calibration or stress-intensity evaluation. The specimen is in the form of a flat plat 25 by 50 cm which is simple to machine and provides about 30 values ofK Ic. The versatility of the machine is demonstrated by making a statistical analysis ofK Ic for 7075-T6 Al by showing the effect of plate thickness on the fracture toughnessK c using a tapered specimen, and by evaluatingK c in 7075 Al as a function of aging temperature in a thermal-gradient-treated specimen.Type of Medium: Electronic ResourceURL: -

ISSN: 1741-2765Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract A modified version of the Kolsky thin-wafer technique is described. The method permits one to obtain the dynamic plastic properties of materials at strain rates as high as 105 sec−1. Data obtained from compression tests on high-purity aluminum are presented for strain rates ranging from 4000 to 120,000 sec−1 at room temperature. Specimen-size effects and the effect of lateral inertia are taken into account in analyzing the data. The results plotted as stress vs. strain rate at constant strains (5 to 20 percent) show that, at the highest strain rates, the stress rises very rapidly with strain rate suggesting that a limiting strain rate is being reached. At the lower strain rates (103 to 104 sec−1), the stress is linearly proportional to the strain rate indicating that the material is deforming in a viscous manner.Type of Medium: Electronic ResourceURL: -
