They can usually experiment more easily; crucially, they can do so repeatedly, under controlled conditions until they have reliable accounts.
Usually these experiments are time consuming, and, because microarray slides and fluorescent labels are expensive, the experiments are also high in costs.
Usually the experiments end before significant embryonic development takes place; in few cases have any live animals been born.
Usually, the experiments report on relatively large structures measuring 30 nm or more in diameter.
Usually, the experiments are conducted with either a cone or plate viscometer consisting of stationary flat plate in which a laminar flow can be exerted on it [26].
Usually several experiments can be considered simultaneously, which requires a multicriteria optimization.
Usually the experiment (or the observed) data do not exactly coincide with theoretical expectations.
Experiments usually have to be designed and fully controlled by the experiment supervisor, and performed by the driver.
Experiments usually escape the test of reproducibility unless they prove something particularly important, controversial or commercialisable.
As researchers, that's what you usually do – lab experiments," says Kerstin Dautenhahn, professor of artificial intelligence at the University of Hertfordshire.
