Gamma caused widespread infection in early 2021 in the city of Manaus, the capital of Amazonas, although the city had already experienced widespread infection in May 2020, [12] with a study [13] indicating high seroprevalence of antibodies for SARS-CoV-2. [14]
The values below are standard apparent reduction potentials (E°') for electro-biochemical half-reactions measured at 25 °C, 1 atmosphere and a pH of 7 in aqueous solution.
P1 Zn 2 SiO 4:Mn: Green 530 nm 11 ns Low For electrons GS ZnS:Cu: Green 520 nm Minutes Long For X-rays NaI:Tl: For X-ray, alpha, and electrons CsI:Tl: Green 545 nm 5 μs Yes For X-ray, alpha, and electrons ND 6 LiF/ZnS:Ag: Blue 455 nm 80 μs For thermal neutrons: NDg 6 LiF/ZnS:Cu,Al,Au: Green 565 nm 35 μs For neutrons Cerium doped YAG phosphor ...
A P1-derived artificial chromosome, or PAC, is a DNA construct derived from the DNA of P1 bacteriophages and Bacterial artificial chromosome. It can carry large amounts (about 100–300 kilobases ) of other sequences for a variety of bioengineering purposes in bacteria .
Cre recombinase is a tyrosine recombinase enzyme derived from the P1 bacteriophage. The enzyme uses a topoisomerase I -like mechanism to carry out site specific recombination events. The enzyme (38 kDa) is a member of the integrase family of site specific recombinase and it is known to catalyse the site specific recombination event between two ...
This line of research identified several connections between the synthesis medium liquid chemistry and important properties of zeolite crystals, such as the role of inorganic structure-directing agents in zeolite framework selection, [57] the role of ion-pairing on the zeolite molecular composition and topology, [58] and the role of liquid ...
The main use for phosphorus tribromide is for conversion of primary or secondary alcohols to alkyl bromides, [9] as described above.PBr 3 usually gives higher yields than hydrobromic acid, and it avoids problems of carbocation rearrangement- for example even neopentyl bromide can be made from the alcohol in 60% yield.
Parts-per notation is often used describing dilute solutions in chemistry, for instance, the relative abundance of dissolved minerals or pollutants in water.The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution.
