Bronchitis is inflammation of the bronchi (large and medium-sized airways) of the lungs. Symptoms include coughing up mucus, wheezing, shortness of breath, and chest discomfort. Bronchitis is divided into two types: acute and chronic. Acute bronchitis is also known as a chest cold. Acute bronchitis usually has a cough that lasts around three weeks. In more than 90% of cases the cause is a viral infection. These viruses may be spread through the air when people cough or by direct contact. Risk factors include exposure to tobacco smoke, dust, and other air pollution.
A squeegee (also squilgee) is a stiff rubber blade mounted on a wooden or plastic handle used to pull water across a flat surface, typically to clean or dry the surface. The squeegee was first used on boats to direct water off the deck and clean away blood and scales left from fishing. Today most people associate the squeegee with cleaning windows, windshields, and acrylic or glass surfaces like shower or tub enclosures. The squeegee is also used to spread paint across silk screens and to smooth photographic paper in the development process. There are many different types and sizes of squeegees for every job, ranging from the basic, personal squeegee to professional models.
A rubber squeegee is used to press ink onto material during the screen-printing process. Screen-printing may be performed to produce images onto t-shirts. Screen-printing flags and patriotic banners was popular during World War I. Stencils can give designs clean edges in screen-printing projects. rubber squeegee is then used to press the ink through the porous areas and onto the paper or fabric below. If the design calls for multiple layers or colors, the ink from the first press is given time to dry, and the process is repeated with a different stencil or different ink color. Ad.
