An eco-column is used to model an ecosystem on a smaller scale. The purpose of an eco-column is to examine how an actual ecosystem would respond to different conditions. Eco-columns typically have three chambers: the aquatic chamber‚ decomposition chamber‚ and terrestrial chamber. The aquatic chamber contains water and an aquatic plant‚ and it is at the bottom of the eco-column. The decomposition chamber contains items that will work as decomposers and as a possible catalyst for plant growth. Examples

his story on the Trajan’s Column‚ and to have the effect he wished to convey. The sculptor wanted to tell the story of the emperor Trajan to the people of Rome and illustrate his victories and achievement by the carvings on the column. He uses the technique “continuous narration” to let the story unfold within the spirals without any interruption. This progression of events is not always consecutive and is sometimes simultaneous. Due to the increasing distance of the column from the ground‚ the sculptor

What is the biggest animal ever to exist on Earth? By considerable measure‚ the largest known animal on Earth is the blue whale. Mature bluewhales can measure anywhere from 75 feet (23 m) to 100 feet (30.5 m) from head to tail‚ and can weigh as much as 150 tons (136 metric tons). That’s as long as an 8- to 10-story building and as heavy as about 112 adult male giraffes! These days‚ most adult blue whales are only 75 to 80 feet long; whalers hunted down most of the super giants. Female blue whales

English 1010-001 Speed Kills? They use the slogan “SPEED KILLS” to brainwash the American public into conformity with the insanely-low speed limits that benefit the insurance companies‚ local governments‚ and all others who profit from them. The arguments that are used to support this ideal are based upon faulty‚ self-serving‚ and biased science. Speed does kill‚ but only if the vehicle runs into something. The speed limit is set deliberately 10-15 mph below the average driving speed on urban highways

Magnetic Resonance Imaging (MRI) is a medical imaging technology that uses strong magnetic fields and radio waves to create graphic images of the body’s anatomical and internal structures (1). MRI relies primarily on the protons in fat and water molecules of the body‚ as these protons respond to the static magnetic field created in ways that allows for a high quality image to be generated (2). These images contrasts specific tissue and different anatomical structures. For example‚ MRI can reveal

“The Master Speed” Throughout the poem The Master Speed‚ Frost addresses the idea that marriage is a sacred bond that must be treasured all through our lives.

as someone waits for them in their respective homes - a mother or a sister or a wife or a child. It is very common scene in small cars that most of the drivers try to light a cigarette while driving at 120 to 140 kilometers per hour. At this speed controlling a steering wheel or balancing a car is not only risky but also dangerous. Another important reason is use of mobiles while driving. It is again very dangerous not only for the drivers but also to the passengers as well. A fraction

the brake pads against a rotor. Breaking harder increases the magnitude of the normal force‚ which results in the increase of the force of friction acting on the rotor. Given that the rotor is attached to the steering wheel‚ as the rotor reduces its speed so does the wheel. With disc brakes on cars‚ the brake can prevent the wheel from turning lot faster than the friction from the road can stop the car from moving. This can cause the wheels to lock‚ sending the vehicle into an uncontrollable skid. Wheel
