What do you mean by ring homomorphism? In ring theory, a branch of abstract algebra, a ring homomorphism is a structure-preserving function between two rings. Is a factor ring a Subring? Definition A subring A of a ring R is a (two-sided) ideal if ar, ra ∈ A for every r ∈ R and every a ∈ A. [An ideal is a subring with left and right absorbing power!] is a ring (known as the factor ring) if and only if A is an ideal. How do you get a ring homomorphism? The evaluation map ek is a function from...

What should be the conductivity of purified water? Purified water is low conductivity (typically 5 microSiemen/cm or less). These applications demand a two electrode conductivity sensor with a cell constant of 0.10 or less. What are the specifications of purified water? USP Standards For Purified WaterpH5.0 to 7.0Chloride (mg/l)0.5Sulfate (mg/l)1.0Ammonia (mg/l)0.03Calcium (mg/l)1.0 What is limit of conductivity? When the change in conductivity (due to uptake of atmospheric carbon dioxide) is less than a net of 0.1 µS/cm per 5 minutes, note the conductivity. 5. If the conductivity is not greater than 2.1 µS/cm, the water meets the requirements of the...

How big does a Frontosa cichlid get? frontosa can grow to 33 cm (1.1 ft) in length. Even captive specimens potentially grow to this size. It has distinct markings with five to seven black vertical bars adorning a white or blue body and head and trailing fins with a distinct blue hue. Are Frontosa cichlids aggressive? Make no mistake, Frontosa Cichlids are predators and are perfectly willing to eat any tank mates small enough to fit, even other cichlids. As long as their neighbors are larger than 3 inches they should be safe. What is this? Frontosas typically are mild-mannered...
