According to Lillie McGarvey, a 20th-century Aleut leader, barabaras keep " occupants dry from the frequent rains, warm at all times, and snugly sheltered from the high winds common to the area ".

In structural applications, high flexural rigidity, thermal stability, thermal conductivity and low density ( 1. 85 times that of water ) make beryllium a quality aerospace material for high-speed aircraft, missiles, space vehicles and communication satellites.

Historically, doppelbock was high in alcohol and sweet, thus serving as " liquid bread " for the monks during times of fasting, when solid food was not permitted.

Estimates for the Ethiopian forces under Menelik range from a low of 73, 000 to a high of over 120, 000, outnumbering the Italians by an estimated five or six times.

Drawbacks of the technology include high energy consumption and long warm-up times from a cold state.

As a result, colour graphics can take up to four times longer to print than standard monochrome graphics, or up to 8-16 times as long at high resolution mode.

Storing a dispersion at high temperatures enables to simulate real life conditions for a product ( e. g. tube of sunscreen cream in a car in the summer ), but also to accelerate destabilisation processes up to 200 times.

Possible costs would include higher rate of crime, higher mortality rates, higher cost of living, worse pollution, traffic and high commuting times.

On the other hand, raising the interest rate is often used in times of high economic growth as a contra-cyclical device to keep the economy from overheating and avoid market bubbles.

Indeed, the energy density of some material involved in the formation of impact craters is many times higher than that generated by high explosives.

Bronze has several characteristics that made it preferable as a construction material: although it is relatively expensive, does not always alloy well, and can result in a final product that is " spongy about the bore ", bronze is more flexible than iron and therefore less prone to bursting when exposed to high pressure ; cast iron cannon are less expensive and more durable generally than bronze and withstand being fired more times without deteriorating.

Lower caste participants consisted of mostly non-farm working immigrants, who at times were provided special privileges and held high positions in society.

According to the Peterson Institute for International Economics and other proponents of demographic structural approach ( cliodynamics ), the basic problem Egypt has is unemployment driven by a demographic youth bulge: with the number of new people entering the job force at about 4 % a year, unemployment in Egypt is almost 10 times as high for college graduates as it is for people who have gone through elementary school, particularly educated urban youth, who are precisely those people that were seen out in the streets during 2011 Egyptian revolution.
