However, repeated exposure to hallucinogens leads to rapid tolerance, likely through down-regulation of these receptors in specific target cells.

However, conservation tillage systems delay warming of the soil due to the reduction of dark earth exposure to the warmth of the spring sun, thus delaying the planting of the next year's spring crop of corn.

However, once contamination has occurred, Star Fleet personnel are allowed to directly intervene on the planet to attempt to minimize the harm as much as possible with an openness in proportion of how significant the exposure has been.

However, persons living at higher altitude can obtain several times more cosmic radiation than at sea level, and long distance airline crews can double their yearly ionizing radiation exposure due to this source.

However, the background due to cosmic rays can vary from 0. 3 mSv / year at sea level to 1. 0 mSv per year in high-altitude cities, which would raise cosmic radiation exposure to a quarter of the total background.

However, at several hundred ppmv, carbon monoxide exposure can induce headaches, fatigue, nausea and vomiting.

Long-term rodent studies to assess cancer risk have so far failed to identify any carcinogenicity from microwave radiation even with chronic exposure levels, i. e., large fraction of one's life span, far larger than humans are likely to encounter from any leaking ovens .< ref > However, with the oven door open, the radiation may cause damage by heating.

However, in situations demanding prolonged exposure to a hot environment or wearing protective equipment, a personal cooling system is required as a matter of health and safety.

However, rather than leave the child to die of exposure, as Laius intended, the sympathetic servant passed the baby onto a shepherd from Corinth and then to another shepherd.

However, for a simple dishwasher with only a single impeller in the base of the unit, glasses and other deep containers both need direct exposure to the jet, and will block liquid from reaching objects behind them.

However since the Second World War land or sea battles have come to rely on air support.

However, unless the airflow is adjusted as well, the flame temperature will decrease because an increased amount of gas is now mixed with the same amount of air, starving the flame of oxygen.

However, its use in terrestrial applications is usually limited by its high reactivity with air.

However, it does suffer from nitrogen embrittlement, reacting with nitrogen from air and forming brittle nitrides at the high temperatures necessary to work the metal parts.

However, Empedocles of Acragas ( c. 495-c. 435 BC ) selected four archai for his four roots: air, fire, water and earth.

However, water conducts sound better than air, so the external ear is unneeded: it is a tiny hole in the skin, just behind the eye.

However when combined with land mines, snipers, barbed wire, and air cover, crossfire became a difficult tactic to counter in the early 20th century.
