most commonly a laser beam is used as the light source. To be more specific an argon laser‚ which produces blue light is most commonly used however‚ some instruments also contain a red helium-neon laser. The laser beam excites a fluorescent tag‚ for example a fluorescent antibody‚ which is bound onto the cells that are within the sample. Before the laser excites the tag it is focused through optics‚ which form an elliptical beam that contains its maximal intensity in the center. Once the laser

plates. In the LB/amp/arabinose agarose plate containing the +pGLO sample‚ fluorescent green colonies developed. This is because the gene which codes for the fluorescent protein‚ GFP‚ is located near the beta lactamase gene on the pGLO plasmid‚ which protects bacteria from the antibiotic ampicillin. When the cell produced beta lactamase to deactivate ampicillin‚ the GFP gene was also transcribed‚ producing the fluorescent protein observed. In the LB/amp plate containing the +pGLO sample white‚ non

It is highly sensitive to acid in the solution sate‚ enabling its wide application as pH-dependent probes. In acidic solutions‚ the ring-opened form is predominant‚ and therefore it is strongly fluorescent. Although this acid-sensitive equilibrium has been well known in solutions‚ its properties in the solid states are not well examined. Therefore‚ relative test of acid gas-sensitive property of RH-PY was proposed in this study. Figure 1. (A) Device

HEAT GENERATED IN APPLIANCES Why do some appliances produce more heat than the others? Most appliances with high power rating are heating appliances.The heating appliances has a heating element like resistors. The resistorsconvert electrical energy into light and thermal energy . It depends on the resistance of material if how much heat can be produced from electricity. Those devices who produced heat‚ the Nichrome wire is an element who is responsible for heating . when we say nichrome

Many things these days are taken for granted and used with great liberty‚ but none more prevalent than the consumption of petroleum based fossil fuels worldwide. As stated in The International Energy Outlook 2006 (Energy Information Administration‚ 2006a)‚ "World oil consumption rose by about 1.2 million barrels per day in 2005‚ after an increase of 2.6 million barrels per day in 2004". Current projections indicate increasing demand for oil by the transportation sector‚ where there is currently not

each petri dish a paper towel was folded to the size of the dish and saturated with tap water. After saturation‚ two WFP seeds were added to each petri dish. The dishes were then labeled for their assigned light condition‚ which was either full fluorescent light exposure or darkness. Plants were left under their assigned light condition for twenty-four hours a day‚ for seven days and watered daily. After seven days‚ plants were retrieved from their environment and stem length‚ plant mass‚ and cotyledon
