Activated Carbon Filters Media [pic]"Activated" carbon filter media is produced by super-heating dried coconut husks in a low oxygen environment‚ using a process called pyrolysis. The resulting "biochar" husk‚ is a purified form of carbon‚ containinglarge amounts of cellular sized surface area‚ negatively charged to attract positively charged toxins. Toxins in the water become attached to the husk’s carbon surfaces.Over time‚ the attractive charge of carbon surfaces are neutralized‚ making it time

The Affective Filter Hypothesis Nowadays‚ studying a second language becomes more and more important‚ so how to grasp the second language well and quickly becomes a significant topic. Since I learned some related theory from this weeks class‚ I found one of the five hypotheses of the natural approaches which attract my attention. In the 1970s‚ Stephen D. Krashen put forward a famous theory Affective Filter Hypothesis‚ and it helps teachers and learners to have a great progress on learning second

Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye‚ and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres (nm)‚ or 400×10−9 m‚ to 700 nanometres – between the infrared‚ with longer wavelengths and the ultraviolet‚ with shorter wavelengths. These numbers do not represent the absolute limits of human vision‚ but the approximate range within which most people can

Problem: Dows light intensity and wavelength affect Photosynthesis? Introduction: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. It produces sugar and other organic compounds such as lipids and proteins. The sugars are then used to provide energy for the organism. Light reaction is the series

1. Do you think that the Interface approach is an example of how a company can successfully apply the CSR filter? Why or why not? 2. Could this approach be applied in the company or organization in which you work‚ have worked‚ or study? Why or why not? 1)I think after reading all the articles and chapters till now‚ this is the first time when i have truly felt CSR could actually be possible and make a difference from an Internal Stakeholder point of view. Profitability is seen to be the number

In photosynthesis‚ light energy is transformed into chemical energy‚ thus chemical energy is the product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplasts‚ using the chlorophyll inside of the chloroplasts‚ while respiration occurs in the mitochondria. Photosynthesis produces oxygen as a by-product‚ while aerobic respiration requires oxygen to even work

Power Outages Louis Armstrong’s “Black and Blue” uses simple questions for someone to recognize both he and Ralph Ellison’s Invisible Man are comparable. To be comfortable and confident in your own skin is a recurring problem for people of color and seems to always be brought up in today’s society. Louis Armstrong goes on to say that “his only sin is his skin” and asks “how will it end?” (Armstrong). Different skin tones have separated all humans to a point of no belonging. Invisible is convinced

the Kirby-Bauer Antimicrobial Susceptibility test (disc diffusion technique). Each group will inoculate his/her own plate of Mueller-Hinton agar with an assigned culture. To that inoculated plate‚ you will then aseptically add sterile filter paper discs (using a disc dispenser)‚ which contain a known concentration of antibiotics. As soon as the antibiotic discs touch the agar‚ the antibiotic will begin to diffuse into the surrounding agar. During incubation the bacteria you inoculated onto the

By employing a short wavelength blue violet laser‚ the Blu-ray Disc successfully minimizes its beam spot size by making the numerical aperture (NA) on a field lens that converges the laser 0.85. In addition‚ by using a disc structure with a 0.1mm optical transmittance protection layer‚ the Blu-ray Disc diminishes aberration caused by disc
