truth behind them: Painting is as good as seal coating: Seal coating is a protective liquid made of coal, petroleum and acrylic and is specifically designed to adhere to asphalt. Once dried, it binds to the asphalt creating a uniform surface so that your asphalt surface is as impervious as a new one. In contrast, paint doesn't bond like seal coating. Paint can peels and weathers away relatively quickly, allowing the asphalt to be exposed to the damaging effects of rain and snow. Paint can also be eroded

creating composites of TiO2 with other semiconductor having a relatively low band gap energy (CdS, ZnO particles) [16, 17], sensitization of TiO2 surface with dyes (thionine) [18]. There are several benefits of using CNTs in a fiber photocatalytic such as TiO2/CNT system because of its unique optical, magnetic, electrical, mechanical, thermal, gas adsorption properties, in addition exhibit large specific surface area to be a good catalyst support and also can be chemically modified to anchor TiO2

of a flat, sloping surface. A lever is a board or bar resting on an object called a fulcrum, and a wheel and axle is made out of a rod going through a wheel. Even though there are many different kinds of energy, the two main ones are kinetic energy and potential energy. Kinetic energy is the energy that an object has while it is motion. The faster an bject moves the more kinetic energy it has. The kinetic energy increases as its mass increases. Potential energy is stored energy, which means that

So when the car crashes it comes back to Newton’s First law when it hits the surface, it will need a crumple zone. A crumple zone is meant to absorb and distribute force, my idea is to use foam at the front of my cars as a crumple zone, so when the car crashes, the foam will crumple with the car and absorbing the force when you hit the surface of the wall, reducing the chance of

What is geothermal energy? : Geothermal energy is thermal (heat) energy that is stored, generated and emanated from the Earth’s core to the Earth’s crust. How is it generated? : The earth core generates geothermal energy through the natural decay of radioactive materials such as Uranium and Potassium. This heat energy is mostly found within magma, which exists below the Earth’s crust. The potential heat energy that exists with the first 100 Kilometers of the Earth’s crust exceeds 500 Kelvin. How

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Whenever an object moves against another object, it feels frictional forces. These forces act in the opposite direction to the movement. Friction makes it harder for things to move. Friction plays a major role in actual roller coaster physics, where mechanical energy which is the sum of potential and kinetic energy is not conserve. There are four types of friction in roller

You take a long walk, hoping to stop for a drink of water. You notice a drinking fountain right in front of Smart and FInal. You bend down for a drink, but then you remember an add that you saw on the news this morning. “No more tap, no more issues. Drink Dasani water and you’ll be safe! You hurry into the store, glancing at the price of the water $2.00. “Well, that’s a lot of money,”you think. You pay and than drink it in about 5 minutes. It bounces of the rim of the recycling can, and falls into

Water Pollution is the addition of harmful chemicals to natural water. Sources of water pollution in the United States include industrial waste, runoff from fields treated with chemical fertilizers, and run-off from areas that have been mined.(Dictionary.com).The issue of water pollution has a long history around the world. Water Pollution is one of the leading causes of death in Africa and some parts of Asia. For some, such as Africans and Americans, the issue of water pollution has a particular

Lab Write-Up The Sacramento River, a meandering river located in Northern California, appears to have changed significantly from 1998 to present day. The winding curves of the river were much more pronounced and dramatic until erosion and decomposition affected the sediment amount in the river, changing its shape. As it flows, it deposits sediment on banks that lie on the insides of curves (point bar deposits), and erode the banks on the outside of curves. The low, crescent-shaped deposit of sediment

be 1 of 28 in the nation. The goal of the IRL is to protect this ecologically significant estuary that is threatened by degradation caused by human activity. The IRL is designated as an aquatic preserve, and Outstanding Florida Waterway, and a Surface Water Improvement and Management (SWIM) Water Body. The IRL is a 156 mile long estuary located in Volusia, Brevard, Indian River, St. Lucie, Martin and northern Palm Beach County. It has three distinct water bodies, Mosquito Lagoon, Banana River

Mott Haven which is 1.181 mi² have been primarily a residential neighborhood in the southwestern section of the Bronx borough in New York City. Zip codes include 10451, 10454, and 10455. This site includes various things such as provisioning services, regulating services, cultural services, and supporting services. This site is also full of water sources, natural gases, and very biodiverse which are being polluted by human activities. Pollution can be physical chemical or biological and can affect

ecologically important for several reasons. To begin with, the region has three wild salmon rivers. It also contains many other wild species such as grizzly bears and stone sheep (Wikipedia). More importantly, “The Sacred Headwaters is rich in mineral and energy resources, particularly coal and coalbed methane”(Wikipedia). As a result, mining industries have been proposing projects on mining its abundant resources. However, the Tahltans and the mining companies have been having trouble finding a balance between

nut attached to it, and the Pipet had to be filled almost to the top with water. Then, an empty glass or cup had to be completely filled with water, and the Pipet had to be placed in it. The Plastic Pipet had to be able to just barely float on the surface. Since it just barely floated, it then had to be placed inside of the 2L bottle, and the bottle had to be sealed with the cap. After this, the bottle had to be squeezed, and the Pipet or “Diver” sank to the bottom. After testing it out to make sure

Water pollution is a very prevalent problem throughout the world. It affects ecosystems, deters the natural food chain, and can cause disease in both animals and humans. But is water pollution affecting natural lakes and ponds in local areas? In this experiment, Daphnia magna will be used in a bioassay to find if water from local areas is habitable for aquatic organisms. Daphnia magna are small freshwater invertebrate organisms. They are commonly used in bioassays and experiments because they are

The South What is crop rotation and what is its purpose? Why was it Introduced? Crop rotation is planting one crop one year and then planting another crop in its place a different year. The purpose of crop rotation was to put certain nutrients back into the ground. For example Now people plant corn and soybeans. Corn takes nitrogen out of the soil and uses that to grow. Then the next year people will plant soybeans in its position, because soybeans put nitrogen back into the soil for the

other chemicals. The surface temperature of the sun is 5500°C and the suns core temperature is 15,000,000°C. 960,000 rounds earths can fit in a hollow sun. The sun is the largest object in our solar system. There are nine planets orbiting the sun. The sun is in the center of the solar system. The sun makes up all around 99.86% of the solar systems must the sun is only one of the

Through my research, I have developed an understanding of the importance of outdoor play. This has helped me to understand how to allow for opportunities to occur for outdoor play. For example, using the weather to my own advantage, if its raining, to take the children out in water proof clothing to play in the rain. This can help children to develop their understanding of the world around them all the whilst playing, which is what the Foundation Phase encourages. I have learnt that there are many

Aeromonas hydrophila is a gram negative rod bacterium. This bacterium spreads widely in various environments, especially in fresh water like in fish cultivation ponds, rivers, lakes, even in sparkling chlorinated drinking water reservoirs. This bacterium is known as a dangerous pathogenic bacterium in water biota like shrimps, oysters, frogs, and fishes (Martin-Carnahan & Joseph, 2005; EPA, 2006). The infection caused by this bacterium can lead to mass dead of fish in short period of time, which
