Fluorescent lamp

A solution of butadiene and meso-tetraphenylporphyrin (100 mg, 0.162 mmol) dissolved in dichloromethane (100 ml, 1.57 mol) in a water-jacketed flask was irradiated with compact fluorescent lamps. The solution was then concentrated in vacuo and the product subjected to column chromatography to yield the product, aldehyde, and unreacted starting butadiene which could then be recycled. 1-Phenylbutadiene…

One aspect that helps change the atmosphere of the room is lighting, Williamson said and lamps create a more comfortable light than the overhead fluorescent ones. "Floor lamps are really good because they stand on their own," Williamson said. "You don't have to have a surface to put them on.” Williamson said also having a room with soft colors and an aromatherapy diffuser can help…

Introduction The electric light bulb has basically remained unchanged for over a hundred years. The new federal energy-efficiency standards have taken effect and are pushing out the old uneconomical light bulbs for more efficient options, such as light emitting diodes. The primary function of LED lighting is for the preservation of energy. This composition will furnish information to home owners about the advantages of shifting to LED lighting, by contrasting the benefits of modern LEDs to the…

Throughout history, humans have been overcome by cursitory to figure out the way our universe works. In the past hundreds of years, there have been numerous discoveries that revolutionize modern civilization and the way humans have thought about Earth. One of the most significant discoveries that humanity has found was the fact that everything is made up of elements. The Noble Gases in particular, set the precedent for what all other elements strive to become. Every element in the periodic table…

absorbed. Conversely, red light and white light is more effective at driving photosynthesis (Reece, 2011). Thus, a hypothesis was created stating that the rate of photosynthesis will be greater with a red light bulb compared to a green or white fluorescent light bulb. The independent variables are the time and the different colored light bulbs, while the dependent variable is the percent transmittance. The variable being tested is the different colors of light: red, green, and…

Rising Temperature Leads to Rising Fear In the future year of 2040, only two and a half decades away, the Arctic may not have any ice during its summer season, due to global warming (“Global Warming Fast”). 2 The global average temperature continues to get higher and melt the polar ice caps because of the amount of carbon dioxide being released into the air. Carbon dioxide is a gas that contributes to the greenhouse effect, which is when the sun’s rays enter the atmosphere and are reflected…

I. Community, District, and School Factors The Carolina Forest area is located in Horry County, South Carolina, between Conway and Myrtle Beach. The area is unincorporated, which means the location is governed by a larger municipal district instead of having their own governing bodies. In the case of Carolina Forest, it is governed by Horry County. There are 21 residential subdivisions in the Carolina Forest area and six public schools, all located in the Horry County School District. In the…

repeated at regular intervals to recognize early sign of glaucoma. Tonometry is the measurement of intraocular pressure (IOP). It is a quick and painless procedure. The patient is given an anesthetic eye drops and applied a fluorescent dye; a small plastic cone attached to the slit lamp, is then placed on the cornea. The pressure measurement is obtained by illumination with blue light. Normal values are around 20 to 21…

The summer of 2017 was a time that I will never forget, filled with fun adventures, friends, and away from occasionally overbearing parents. My most Notable moment from this summer was my school trip to Italy and Greece, more specifically the time that I climbed a mountain in the early hours in the morning with friends. I am not an active person, much less a morning person, I was not prepared for the laborious task of climbing a steep rocky mountain. In the end, that very moment in time was…
