In one sentence, describe what the following article is about: Sterile saline, such as that found in first aid kits, is the ideal substance for flushing a contaminated wound. The physical act of washing removes the bacteria and debris, while the saline is so similar to the pH of the body tissues that it causes minimal tissue damage. The trick to using saline is to use large volumes and keep washing until the area looks clean. For a very dirty wound with lots of mud or gravel in it, an alternative is to boil water and then let it cool. Use this water to literally wash the area clean. There is a slight risk using water that it will damage the exposed tissue bed, as it does not have the same composition as body fluids and therefore draws fluid out of damaged tissue. However, medical studies have shown that using tap water to irrigate a wound does not have a huge impact on whether the wound eventually gets infected. Salt water has natural disinfectant properties and is a good standby for cleaning a cat's wound. To make a salt water solution boil the kettle, measure out a cup of water,and add half a teaspoon of salt. Then stir to dissolve and leave to cool. This salt water is also around the same composition as tears and body fluids, so it is less damaging to exposed tissue than commercial disinfectant solutions or water alone.
Summary: Find some sterile saline. Boil some water and use it once cooled. Make a salt water solution.

In one sentence, describe what the following article is about: You don't need to install anything to find the XPath in Internet Explorer. Open the website that contains the element you want to inspect. The developer tools panel will appear at the bottom of the window. You'll find this in the upper-left corner of the developer tools panel. This will select it and highlight the code for it in the DOM Explorer. Each of the tabs along the bottom of the panel is an XPath expression for the element you have selected. You cannot copy it in XPath format like you can in Firefox with Firebug.
Summary: Open the website you want to inspect in Internet Explorer. Press F12 to open the developer tools. Click the "Select element" button. Click the element on the web page that you want to inspect. Note the XPath information at the bottom of the panel.

In one sentence, describe what the following article is about: To calculate the normal force of an object at an angle, you need to use the formula: N = m * g * cos(x) For this equation, N refers to the normal force, m refers to the object's mass, g refers to the acceleration of gravity, and x refers to the angle of incline. Example: Find the normal force of a block with a mass of 4.2 kg, sitting on a ramp with an incline of 45 degrees. The cosign of an angle equals the sine of the complementary angle, or the adjacent side divided by the hypotenuse of the triangle formed by the incline. This value is often determined by a calculator, since the cosine of any angle is constant to that angle, but you can compute it manually, as well. Example: cos (45) = 0.71 The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Note that the gravitational acceleration at the Earth's surface is a constant: g = 9.8 m/s2 Example: weight = m * g = 4.2 * 9.8 = 41.16 In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline. Example: N = m * g * cos(x) = 41.16 * 0.71 = 29.1 The previous step should complete the problem and give you your answer. Note that for an object sitting on an incline, the normal force should be less than the weight of the object. Example: The normal force is 29.1 N.
Summary:
Use the right equation. Find the cosine of the angle. Find the object's weight. Multiply the two values together. Write your answer.
