Throughout the expedition Nansen continued to experiment with equipment and techniques, altering the designs of skis and sledges and investigating types of clothing, tents and cooking apparatus, thereby revolutionising methods of Arctic travel.
The technique involves altering the genetic makeup of the pigs so that they do not develop a pancreas and then injecting human cells that will go on to make replacement organs inside the animals.
And the technique of altering genes in their embryos could conceivably work with human embryos as well, raising the specter of so-called designer babies.
There are many properties of bioresorbable microparticles that can be tailored for a specific application by altering the type of polymer, fabrication technique, and parameters used to synthesize the particles.
The new technique involves slightly altering the composition of a gas mixture flowing through a capillary tube by adding a small stream of perturbation gas.
It has been exploited as a remarkable molecular biological technique for altering the genetic construction of bacteria, for locating bacterial genes, and for many other genetic experiments.
A technique for altering the natural progression of eruption is employed by orthodontists who wish to delay or speed up the eruption of certain teeth for reasons of space maintenance or otherwise preventing crowding and/or spacing.
The AMT technique was optimized by altering the concentration of acetosyringone, the ratio and concentration of A. tumefaciens and A. aculeatus cells, the duration of co-cultivation, and the status of A. aculeatus cells when using conidia, protoplasts, or germlings.
Many techniques for altering the genetic code of an enzyme are covered by patents, which means that a company that bioengineers the enzyme must be careful not to use patented techniques.
State regulators arbitrarily declared that "altering the shade of teeth, such as is done by current whitening techniques is the practice of dentistry".
