(h) Hydraulic crash barriers and bollards at vehicular gates.

So, let's start with one, which is hydraulic technology.

They rely on the supply of external energy into the reservoir in the form of injecting fluids to increase reservoir pressure, hence replacing or increasing the natural reservoir drive with an artificial drive.

This is an example of a simple machine, and it's a hydraulic machine.

The Emperor Constantine built it as a reservoir... 1,600 years ago.

Implementing water protection measures to minimize radionuclide seepage into Kiev reservoir through watercourses

It also contains the Apanás reservoir, with an area of 51 square kilometres.

In 2010 and 2011, I helped the Durango community in southwest Colorado develop a recreation management plan for this reservoir just outside of town, a new reservoir, a Bureau of Reclamation project.

Zhang Heng was the first in China to add an extra compensating tank between the reservoir and the inflow vessel, which solved the problem of the falling pressure head in the reservoir tank.

Hydraulic mortar was not available in ancient China, possibly due to a lack of volcanic ash.

Because there's no oxygen there, it's the largest reservoir of hydrogen sulfide on Earth.

The sea is everything an immense reservoir of nature, where I roam at will.

These systems use a flywheel and valve attached to a hydraulic line that feeds the brake cylinders.

In addition, a hydraulic servo system located in the wings would activate the Volitan's performance sail system.

Human settlements in watersheds may modify hydraulic systems and destabilize slopes, thereby increasing flood and landslide hazards.

Meanwhile, civilians in these zones continue to constitute a reservoir of manpower for the guerrillas.

So this created a reservoir 600 kilometers long, one of the largest reservoirs ever created.

The reservoir must also be permeable so that the hydrocarbons will flow to surface during production.

The Sobradinho reservoir is one of the largest artificial lakes in the world, with an area of .

The Navy water source is a surface reservoir (Fena Lake) in the southern part of the island.

Neither the source of the outbreak nor the reservoir where the virus hides between outbreaks is known.

In the northern city of Korhogo, the supply reservoir is nearly dry, causing an acute water shortage.

Of course, technological advances, like hydraulic fracturing ( fracking ) in the shale gas industry, could increase supply and therefore lower prices.

(j) Technologies and plants for the exploitation of solar, wind and mini hydraulic (small waterfalls, waterworks and irrigation canals) energies

Because there's no oxygen there, it's the largest reservoir of hydrogen sulfide on Earth. Shipwrecks are perfectly preserved.

Sometimes an existing mill pond or other artificial reservoir is available and can be adapted for power production.

Today s Russia is a gigantic reservoir of raw materials, and its economy relies heavily on commodities mining and drilling.

It normally works by admitting water from a cold water reservoir into a flexible hose in the base of the reservoir leading directly to a thin metal tube or heating chamber (usually, of aluminum), where a heating element surrounding the metal tube heats the water.

River basin organizations such as that established for the Nile, Niger, or Senegal rivers help facilitate dialogue between states that share hydraulic resources.

States shall take all appropriate measures to prevent, insofar as possible, any pollution of, and the degradation of the hydraulic integrity of, aquifers.

It means large scale hydraulic fracking for gas and massive strip mining operations for coal, the likes of which we haven't yet seen.

Rural hydraulic projects, which ensure access to water for these populations over large stretches of land, can prove to be efficient conflict prevention tools.

Indeed, thanks to the new techniques in hydraulic fracturing and horizontal drilling, shale gas may well become the dominant energy resource of the future.

If your high pressure hose pipe or hydraulic line bulges a little, you just wrap some tape around it, it really is that simple.

The reservoir volume is about equivalent to the annual flow of the Nile at the Sudanese Egyptian border (65.5 billion cubic meter).

Reservoirs By far the largest reservoir of Earth's oxygen is within the silicate and oxide minerals of the crust and mantle (99.5 ).

The biggest reservoir, the ocean, was the least well measured, until more than 3,000 Argo floats were distributed around the world's ocean.

Short settling time This hydraulic selection pressure on the microbial community allows the retention granular biomass inside the reactor while flocculent biomass is washed out.

However, while 90 of world reserves of hydraulic energy are concentrated in underdeveloped regions like sub Saharan Africa, HVDC technology remains the preserve of developed countries.

This area, which contains perhaps the largest reservoir of biodiversity left on earth, is exploited by many countries, but managed by no one.

But, while the country had a vast reservoir of talent to be tapped, it lacked the necessary infrastructure to utilize that human capital.

These include natural water displacing oil downward into the well, expansion of the natural gas at the top of the reservoir, expansion of gas initially dissolved in the crude oil, and gravity drainage resulting from the movement of oil within the reservoir from the upper to the lower parts where the wells are located.

Second, the costs of the insurance premium the outsize, largely dollar denominated reservoir of China s foreign exchange reserves have been magnified by political risk.

Whereas extraction of America s extensive reserves of natural gas was previously thought to be unfeasible, technologies such as hydraulic fracturing ( fracking ) have ushered in a shale gas revolution.

With a large reservoir of surplus savings and a budget deficit of less than 2 of GDP, it has the wherewithal to fund such efforts.
