How has technology been used to address issues related to sewage?
The Roman Empire built large systems of waterworks to both supply water and remove sewage from their cities, unfortunately Roman sewers usually just emptied into the nearest river polluting it.
It was not until the middle to late 1800s that Europe again created similar systems for handling sewage and not until the early 1900s that the addition of sewage treatment plants became common to minimize the pollution of the rivers the sewage was being dumped into.
Frozen glacial water and underground natural springs are considered pure water that are non manmade purified fit for human consumption.
High pressure tells me of a possible head gasket problem. Have the cooling system pressure tested by a reputable garage; this will answer some questions.
How do you measure legroom and headroom in a car What are the measurement points?
"Rear legroom is horizontal distance between the front edge of the rear seat and front seatback. Headroom is measured from the seat swab to the roof lining."
Not a very good answer. Does not specify if the front seat is in the forward or back position when measuring rear legroom.
Pollution is defined as "The presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects."Simply put there was a problem situation caused by the introduction of materials to the environment and a name for it was created.
Pollution can be created naturally (volcanos, erosion, dissolving of poisonous materials from rocks) or by human activities (industrial effluents, raw sewage discharges, carbon dioxide emissions)
At one time in Earth's history oxygen was a pollutant which wiped out the anaerobic life forms. This the "badness" of pollution is dependant on the situation.
What is the history of lifting devices?
Primitive techniques back in ancient Egyptian cultures used log rollers, greased logs, ropes, and droves of manual labor. Bouyancy in ships made of reeds and grass were loaded with sand to lower a boat in the water. Stones were rolled on, and then sand emptied out to make the boat float. Sand piles, and smaller stone wedges were used in conjunction with the physics of a Fulcrum, in order to use a stone's own weight to stand it upright (for pillars and columns). "Block and Tackle" was the next mechanical evolvement (use of pulleys) to lift objects. Lifting technology really didn't emerge until the start of the Industrial Revolution in approximately 1812. Incremental stages that increased productivity were Steam Engines, followed by the Combustion Engine, followed by Hydraulics and Electrical Motors, and now magnetic levitation is a science incorporated into the newest high-speed trains.
What were the negative effects experienced by participants in the Zimbardo prison experiment?
The American educational network PBS did an excellent series in 2001 called "Discovering Psychology," and in episodes 19-20, it addressed such things as the psychological effect the situation can have upon how human beings act. In one segment, it discussed the 1971 Prison experiment, with Dr. Zimbardo (host of the series) looking back on it. It also showed a follow up, where students (both the "guards" and the "prisoners") met after a few months and talked about their feelings regarding the experiment.
It is clear from that segment that the participants were still upset. The "prisoners" were shocked that classmates they thought they knew were willing to treat them so brutally, and the "guards" were still embarrassed that they had gotten so caught up in the role that they acted in such an inhumane manner. Even Dr. Zimbardo noted that he too had become caught up in his role of the "warden," and his reaction surprised him. Although he was a trained psychologist, he admitted he had lost perspective and found himself thinking like a prison warden. That was one reason he called off the experiment-- the realization that it does not take much (in this case, some isolation, uniforms, and arbitrary hierarchies of power) to make otherwise decent people behave in unethical or cruel ways.

Sewage purification in natural way:
Sewage is purified by microorganisms present in sewage in an environmentally favourable condition to them. Microorganisms purify sewage either in the presence of oxygen or in the absence of oxygen also. When dissolved oxygen is completely utilised resulting no dissolved oxygen in the sewage, sewage attains a stingy condition commonly known as septic condition.

What are the pros and cons to a 1989 Camaro 2.8l?
Easy to find parts as most junk yards still have an abundance of Camaros hanging around, and there are a few fairly reliable sites dedicated to thirdgen parts, though slightly more expensive than the junk yards.
Fairly good on gas if it has been taken care of, and a turbo is fairly easily installed if you want a reasonable amount of performance (there is a lot of space to work around a 6 cylinder.) A throttle body spacer is also easily installed along with a k&n air filter, adding a few horse power because of improved air intake.... in short, the car is easily modded, and there is an abundance of support online on how to do so... switching the ignition coil out is also a good idea.
Lots of body mods and accessories available... the car just looks good pretty much no matter what you do to it.
Cons:
The 2.8 doesn't start out with a lot of balls, so if you ever intend on racing, and don't care too much about fuel efficiency, then an 8 cylinder is a better option than a 6 with a turbo, and switching it out later isn't really a smart idea financially.
How long does it take a steel can to break down in a landfill?
We still don't know how much time is required. Were still counting. We do know that it is well in excess of 50 years. 50 year old recognizable hot dogs and readable news papers have been unearthed from low tech. land fills so, steel cans will remain in our landfills for a long time.
