Briefly, we first fit a full model will all main and interaction effects, and then we simplify the model by removing the non-significant terms (starting with the highest interaction term), testing to see if model fit has significantly changed.
The study is the first long-term test to suggest that psychiatrists' tentative interest in hallucinogens and other recreational drugs — which have been taboo since the 1960s — could pay off.
Long-term testing to determine resistance to static loading is described.
Well, there are probably lots of long-term tests to be done, and even then, it's 50% more expensive than regular road materials.
Furthermore, the stability of the photocatalysts is examined through long-term tests to verify their good durability.
One beam was cast un-propped and was kept unloaded for the whole duration of the long-term tests to measure shrinkage effects.
New short-term tests to predict mutagenesis and possible carcinogenesis are validated using data from the NTP-CB.
The term "test" is used to refer to any procedure used to gather information on the health status of an individual.
Within 90 h, 59 water stress periods were performed, yielding a similar performance degradation as the long term test with respect to the membrane conductivity.
A time-hydration/temperature equivalence method (Sherby Dorn) is suggested as a method to use short-term test data to estimate rupture times for other conditions.
