Introduction of TOPIC

De-icing is defined as the removal of existing, snow, ice, frost, etc., from a surface. De-icing is very important in winter in places in the north and sometimes in really cold places in the autumn. De-icing was first used to de-ice snow and ice on roads to so that all forms of transportation can continue in extreme cold weather and also has an important impact for making the roads safer for traffic. De-icing started around the 1930’s and became more popular by the 1960´s. Ice or snow can be removed mechanically through pushing or scraping, or by heating, or by using chemicals to lower the freezing point, or by a combination of these methods.

There are many chemicals that are used to de-ice surfaces. Sodium chloride (salt) is used the most for de-icing, because it isn’t expensive and always is available in big quantities. It is spread on the icy roads by specially designed snowplows or dump trucks, with sand and gravel. The salt works by dissolving into the rain or sleet on roads and lowering the freezing point, thereby melting the ice and snow or even preventing it from forming. Since salt water freezes at -18 degrees Celsius it is pointless when the temperature goes down below this level. Getting rid of ice has many benefits, but sometimes if you have too many chemicals it can have a bad effect on the environment. Salt water also has a strong tendency to break down objects. It rusts th

Everywhere across the U.S during the winter, cities put tons of salt and other deicing materials on roads, streets, motorways, and airport runways. The melting and snow, ice, and chemicals run into vegetation and soil on sides of roads. After that, they travel into the U.S waterways under the ground. When the salt is put on roadways, it attracts deer, squirrels and other animals which means that animals could get run over by a car more often.

Usually sand is used instead of salt incase salt isn’t available. If too much is used, some of the sand could be found as dust particles in the atmosphere, creating more air pollution. During winter, the U.S stock up on salt and other tools to face de-icing. In the U.S, usually more than $2.5 billion is spent on de-icing.

On the floor, when there is really cold weather and precipitation, de-icing an airplane is very important. Frozen objects cause very important control places to be rough and uneven, which can mess up smooth airflow and making the ability of the wing to get lift almost impossible and increasing drag. This situation can cause drag. “If large pieces of ice separate when the aircraft is in motion, they can be ingested in engines or hit propellers and cause catastrophic failure.” Frozen objects can easily block control places, stopping them from moving properly. “Because use of this potentially severe consequence, de-icing is done at airports where the temperature were likely to be around 0 degrees Celsius.” During flight, most droplets of very cooled water often exist in stratus and cumulus clouds.

They turn into ice when they are hit by the wings of passing airplanes. De-icing techniques are also used to make sure that engine inlets and various other sensors around the edges of the airplane are color of ice and snow. De-icing on the floor is mostly always done by spraying airplanes with a de-icing fluid made from propylene glycol, almost the same to ethylene glycol antifreeze used in car engine coolants.

Vitamin C water-soluble

Vitamin C is a water-soluble vitamin that is naturally found in citrus fruits, tomatoes, and leafy green vegetables. It is a well known fact that Vitamin C is extremely vital in the human diet. Vitamin C is known for its numerous health benefits such as prevention against immune system deficiencies, eye diseases, skin wrinkling and much more. It was discovered that scurvy is primarily caused by a deficiency of this vitamin. The needs of Vitamin-C vary per person but the RDA (Recommended Daily Allowance) for Vitamin-C put forward by the Food and Nutrition Board of the National Research Counsel is 60 mg/day for adults and an additional 20 mg/day is recommended for pregnant women. Women who are lactating are strongly advised to take an additional 40 mg/day so that adequate of the vitamin will be present in the breast milk. Due to the unstable nature of ascorbic acid, it oxidizes...

Drainage and Dewatering

In the saturated soil mass, the process of withdrawl of superfluous water from it whether in natural or any artificial form is referred as drainage. Before any kinds of engineering works for example excavation for basement of foundation for any structure or for foundations of dams, mining projects etc., excavations are widely popular below the ground water level. To perform such kinds of excavations, the ground water has to be lowered to the lowest point of excavation in order to obtain workable dry place for the construction work. In this process, drainage is also an essential part of it in order to decrease pore water pressure and minimize the seepage effect which certainly betters the strength and effective strength of it as well as increases safety and formulates stable excavation. So it can be extracted that generally in waterlogged areas, drainage helps for lowering the water table and enables to...

Water molecule structure

The water molecule itself is comprised of a single oxygen atom and two hydrogen atoms. It is the attractions between these atoms however that give water one of its most important features. Whilst covalent bonds do form to keep the three atoms together, their proximity to one another leads to an uneven arrangement of electrons. This leads to the two hydrogen ends becoming slightly positively charged, with the oxygen atom becoming slightly negatively charged. The difference in charge means that water is described as a dipolar molecule. Water’s polarity, when combined with its abundance, means that it is often described as the ‘universal solvent’. With the exception of non-polar molecules, all polar and ionic substances will form weak hydrogen bonds with water molecules, thus forming a solution. This is important as many of the chemical reactions which take place within both plant and animal cells use water as a solvent....
