(1) Nuclear weapons could be used to perturb the orbit of an asteroid

(2) It could change the heating structure of the atmosphere and perturb the climate system in ways we don't understand now.

(3) External factors that could perturb development include temperature and environmental chemicals.

(4) In this case, inverting one element at a time might perturb its function whereas inverting them both at once might be less detrimental.

(5) In this way, we see that the two systems engage in an exchange, a feedback loop of information and effect, which serves to further change or perturb each system.

(6) Drugs perturb the system through increasing or decreasing transmission or transmitter levels, or up or down regulating receptor populations.

(7) But how do mass extinctions perturb these systems in the first place?

(8) Did you know that pressure from sunlight alone is sufficient to perturb the orbit of a satellite travelling in the solar system?

(9) If we perturb a system that has a rational frequency ratio, then it can easily be shifted into a chaotic situation with irrational frequencies.

(10) By their calculations, it wouldn't take much to perturb our own system, either.

(11) Many suggest that global warming will perturb the climate system so much as to even initiate an Ice Age.

(12) The failure of a laboratory's computer system has the potential to disrupt work flow, compromise business interests, and delay or perturb patient care.

(13) The future of experiments to test the behavioral role of neurons in vertebrates lies in using reverse genetic tools to perturb function.

(14) The challenge is to perturb the system in a cell specific way to examine the behavioral consequences.

(15) String theory is meant to be some approximate perturbative expansion of some theory not yet known.

(16) What perturbs me though is the complete lack of value I have received from my taxes, that I have faithfully paid towards public health over the years.

(17) If their contributions to behavior are understood then one should be able to predictably alter the behavior by perturbing the activity of the neurons.

(18) I was particularly perturbed because, in the accompanying brochure, the drink was bright blue.

(19) Such measurements can then be compared with predictions of perturbative QCD, a relatively tractable corner of the full theory.

(20) He said local residents were perturbed by this and felt there was the potential for the emergency services to get confused.
