Manganin is a trademarked name for an alloy of typically 84.2% copper, 12.1% manganese, and 3.7% nickel. It was first developed by Edward Weston in 1892, improving upon his Constantan (1887). Manganin foil and wire is used in the manufacture of resistors , particularly ammeter shunts , because of its virtually zero temperature coefficient of ...
Manganese is an essential human dietary element and is present as a coenzyme in several biological processes, which include macronutrient metabolism, bone formation, and free radical defense systems. Manganese is a critical component in dozens of proteins and enzymes. [ 8 ]
Dogs in Canada was a print magazine published by the Canadian Kennel Club (CKC) from 1889 to 2012. The publication went through different title changes, starting with Canadian Kennel Gazette, then Kennel and Bench, and finally Dogs in Canada. Issues were published monthly, along with an annual edition. [1]
Very importantly, constantan can be processed for self-temperature compensation to match a wide range of test material coefficients of thermal expansion.A-alloy is supplied in self-temperature-compensation (S-T-C) numbers 00, 03, 05, 06, 09, 13, 15, 18, 30, 40, and 50, for use on test materials with corresponding thermal expansion coefficients, expressed in parts per million by length (or μm ...
Then the dog is given Vitamin K supplementation for 3 to 4 weeks, depending on the type of poison. At the end of treatment, the clotting times should be tested again. The prognosis is good in these cases. However, if the dog is already showing signs of poisoning, it is too late to try to remove the poison from the body.
The magainins are a class of antimicrobial peptides found in the African clawed frog (Xenopus laevis). [1] The peptides are cationic, generally lack a stable conformation in water but form amphipathic α-helix in membranes; their mechanism against micro-organisms is unclear but they disrupt the cell membranes of a broad spectrum of bacteria, protozoa, and fungi.
Chronic exposure to excessive manganese levels can lead to a variety of psychiatric and motor disturbances, termed manganism. Generally, exposure to ambient manganese air concentrations in excess of 5 micrograms Mn/m 3 can lead to manganese-induced symptoms.
Dog meat were consumed in some pre-colonial Philippine ethnic groups during certain shamanic rituals and special occasions. However, dog bones are very rarely found in middens in archaeological sites, in contrast to pig and deer remains; and most complete dog remains in archaeological sites are of dog burials near or beside human graves. This ...
