Dexter (also known as Dexter exchange or collisional energy transfer, colloquially known as Dexter Energy Transfer) is another dynamic quenching mechanism. [12] Dexter electron transfer is a short-range phenomenon that falls off exponentially with distance (proportional to e −kR where k is a constant that depends on the inverse of the van der Waals radius of the atom [citation needed]) and ...
This effect can be used to study molecular geometry and motion. An example of its use is in TaqMan or invader assay, SNP genotyping methods. For instance, a hairpin loop with a fluorophore and quencher at the base of the stem is used. An unlabeled SNP specific PCR primer (one of many) with a specific 5' tail binds to the sequence to be probed ...
Hair loss is originally seen in areas of repeated grooming or trauma, for instance the neck because of contact with a collar. Hair regrowth may occur, but the hair will be even weaker and the pattern will repeat. The dogs are affected between the ages of two and four years, and it is most commonly seen on the back towards the tail.
Dog grooming refers to the hygienic care of a dog, a process by which a dog's physical appearance is enhanced. A dog groomer (or simply "groomer") is a professional that is responsible for maintaining a dog’s hygiene and appearance by offering services such as bathing, brushing, hair trimming, nail clipping, and ear cleaning.
Some dogs are able to use their tails to navigate in the water, and retrievers tend to be especially good at it. Number 2: The tail is an extension of the spine. It's much more flexible, however ...
A dog's coat is composed of two layers: a top coat of stiff guard hairs that help repel water and shield from dirt, and an undercoat of soft down hairs, to serve as insulation. [1] Dogs with both under coat and top coat are said to have a double coat. Dogs with a single coat have a coat composed solely of guard hairs, with little or no downy ...
Quenching can also be accomplished using inert gases, such as nitrogen and noble gases. Nitrogen is commonly used at greater than atmospheric pressure ranging up to 20 bar absolute. Helium is also used because its thermal capacity is greater than nitrogen.
Chiengora, also called "dog wool," is yarn or wool spun from dog hair. The word is a portmanteau of chien (the French word for dog) and angora and was coined by an American spinner, Annette Klick. [1] Dog hair is up to 80% warmer than wool [2] and is not elastic.
