Relatively harmless ancestors gradually or step-by-step evolve into "pathogens;" the host develops adaptive defense mechanisms, which in turn select for new virus "variants;" eventually, equilibrium is reached between infection and host defenses.
"Letting Nukes Happen" (editorial, May 16) claims, without empirical substantiation, that Iran, along with North Korea, is step by step developing its capability to build nuclear weapons.
In this situation, organizations and firms tend to keep balance and step by step develop their competency.
Using a step-by-step manual developed by the MATICCE study workgroup, the researchers trained the PEC members in a strategic planning process that acknowledged the adaptive complexity of the system and mobilized the natural organizing ability and creativity of staff and stakeholders (Plsek & Wilson 2001).
The influence on flutter instability of each of the aerodynamic derivatives, which were obtained by pressure measurement on the side surface of 2-D rectangular cylinders with various side-ratios B/D (B is the chord length, D the height) between 5 and 20 under the 1DOF heaving/torsional forced vibration, is discussed through a "step-by-step method" developed here.
"In Area C, which is 60% of the West Bank, Palestinians have got to be able step-by-step to develop it," says Tony Blair, who represents the Quartet of Middle East peacemakers and has been working on a Palestinian economic initiative.
A series of laboratory tests were conducted based on the step-by-step design procedure developed.
Following a step-by-step procedure recently developed by the authors, two pairs of metal hydrides were selected for the CCHP system.
In this paper, a numerical step-by-step approach is developed to estimate shakedown limits of pavements with Mohr Coulomb materials.
Taking all output harmonics into account, a detailed step-by-step procedure is developed to systematically determine the nonlinear parameters from a small set of simulation or experimental data.
A step-by-step workflow was developed and used to take patients' Digital Imaging and Computing in Medicine magnetic resonance brain images through a process resulting in illustrative 3D printed brain and hippocampus models that clearly demonstrate the progressive degenerative changes caused by Alzheimer's disease.
