The general nature of shopping focused price comparison websites is that, since their content is provided by retail stores, content on price comparison websites is unlikely to be absolutely unique. The table style layout of a comparison website could be considered by Google as "Autogenerated Content and Roundup/Comparison Type of Pages". [ 17 ]
For example, an H3-24L has two engines, four solid rocket boosters, and a long fairing, whereas an H3-30S has three engines, no solid rocket boosters, and a short fairing. [17] W-type fairing is similar to L-type except wider 5.4 m diameter. [Note 2] As of November 2018, three configurations are planned: H3-30, H3-22, and H3-24. [17]
Ozone in the ozone layer filters out sunlight wavelengths from about 200 nm UV rays to 315 nm, with ozone peak absorption at about 250 nm. [55] This ozone UV absorption is important to life, since it extends the absorption of UV by ordinary oxygen and nitrogen in air (which absorb all wavelengths < 200 nm) through the lower UV-C (200–280 nm ...
Protonated ozone: Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Hydrogen ...
An ozone monitor of this type operates by pulling an air sample from the atmosphere into the machine with an air pump. [3] During one cycle, the ozone monitor will take one air sample through the air inlet, and scrub the ozone from the air; for the next cycle, an air sample bypasses the scrubber and the ozone value calculated.
The ozone layer peaks at 8 to 15 parts per million of ozone, [1] while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9 to 22 mi) above Earth, although its thickness varies ...
Ozone MNB gives the same inactivation rate same like conventional ozonation for the target pathogen E.coli, but here in the case of microbubble technology, the ozone dose was lower. [23] As higher mass transfer leads to lower ozone dosage so, this ozone MNB technique is promising and beneficial for the existing water treatment plants. [24]
The pre-order feature allowed buyers to set a price and quality rating of a particular item they would like to buy. Sellers saw the pre-order listed when they put an item up for sale and could sell it to the buyer if they agreed with the buyer's price. The company took a commission of every completed sale. The seller was responsible for ...
