Highway agencies around the world strive to improve practices for infrastructure maintenance and rehabilitation, using project delivery policies that range from total 'in-house' responsibility to complete privatization, with a number of flexible contracting policies such as performance-based contracting, variants of design-build-maintain, and lane rentals among others between these two extremes.
The principles of the magnetic propulsion (Prog Aerospace Sci 2001 37 245 61) allow to substantiate the proposed application and variant of design of the magnetic flight vehicle, to clarify its advantageous properties and to determine the main problems to be solved for its creation.
In order to assemble a robust set of variants for design of the 600 k array, the selected set of 1.2 M variants was used to genotype 285 DNA samples from 280 diverse worldwide maize inbred lines and hybrids for the evaluation of variant performance (Additional file 1: Table S4).
The TsKB-17 design bureau proposed variants of the design with both cruise and ballistic missiles.
Less common variants of crossover designs include the Latin square design, the stepped wedge design, and the randomized withdrawal design.
This argument forms the core of intelligent design, a neocreationist movement seeking to establish certain variants of the design argument as legitimate science, rather than as philosophy or theology, and have them be taught alongside evolution.
We discuss variants of trial designs, quasi-experimental designs, systematic reviews, programme evaluations, process evaluations, qualitative studies, and economic evaluations.
More than 60% endorsed variants of intelligent design and 31% subscribed to young-earth creationism.
The exhibition features two elaborate aluminium cuttings and several screen prints with variants of the design.
At the same time, a biologist might want to test 10,000 different variants of a design with minor alterations in each.
