The water quality of the U-High creek was excellent because it had pollution sensitive micro-invertebrates. However‚ not all creeks are this way. One example of humans polluting creeks includes farmers’ pesticides and fertilizers that soak through the ground and travel into the water (Lenntech‚ 1998-2016).

supply electricity to cities in the late 1880s is often called the ’War of Currents ’‚ as this battle ultimately decided which type of current became the standard for the generation of electricity today. Due to different advantages and disadvantages‚ Edison promoted direct current (DC) for electric power distribution‚ whereas Westinghouse and Nikola Tesla both advocated alternating current (AC). Edison ’s direct current was initially the standard for the United States for electricity distribution

Situation of 3D printing I am Simon and lets talk about the situation of 3D printing. I divided my speech into two parts. The first one is current thoughts and the work of the high-end engineer and how do the engineer think about the future development. And the second part is about the difficulty in making this technology popular.
