TECHNOLOGIES BEHIND LIQUID CRYSTAL DISPLAY (LCD) Brief Overview- A thin‚ flat electronic visual display that uses the light modulating properties of liquid crystals is known as a liquid crystal display. Direct light is not emitted by LCDs. Displaced cathode ray tube (CRT) displays of LCDs are used in most applications. Two sheets of polarizing material‚ are used in LCD displays‚ with a liquid crystal solution between them. The crystals align as a result of an electric current‚ so that light

Personal Strength Personal strength is more than just a physical word. It is a word of high stature and can only be defined by searching deep with in ones’ self. All too often we do not think about our personal strength until a situation arises that causes us to use this natural attribute. We have all had situations in our live such as the loss of a loved one‚ which have tested our personal strengths. Personal strengths are only defined by incidents‚ or knowledge of incidents that surround our lives

The Ideal Gas Law Lab taught me that hydrogen is lighter than air‚ and can be ignited. The materials used for the experiment include 0.05 grams of magnesium‚ 1M H2SO4‚ water‚ a 100mL graduated cylinder‚ and a beaker. The hydrogen can be ignited with a match. First‚ the beaker is filled with water. The acid is then added to the graduated cylinder‚ with about ¾ inch left at the top‚ which is space for water. Afterward‚ the magnesium is added to the graduated cylinder‚ and it is inverted upside down

It’s a Tuesday. I’m finishing my workout at my neighborhood gym. I walk into the locker room‚ throw my clothes off‚ and head to the showers. The water is warm. I’m feeling like a real go-getter. The endorphins‚ the steam – it’s relaxing. Veeery relaxing. I take a handful of the shower gel that the gym supplies in buckets and start lathering up. I’m making sure things are clean down there. Really‚ really clean. (Not really‚ readers – I’m jerking off. Duh.) So I’m a showerbater; I admit it. I like
