Ischemic ATN occurs when the tubular cells do not get enough oxygen, a condition that they are highly sensitive and susceptible to, due to their very high metabolism. Diagnosis. Acute tubular necrosis is classified as a renal (i.e. not pre-renal or post-renal) cause of acute kidney injury. Diagnosis is made by a FENa (fractional excretion of sodium) > 3% and presence of muddy casts (a type of granular cast) in urinalysis.
A Rhyming Couplet is two line of the same length that rhyme and complete one thought. There is no limit to the length of the lines. Rhyming words are words that sound the same when spoken, they don't necessarily have to be spelt the same.
A couplet is two lines of poetry that usually rhyme. Here's a famous couplet: Good night! Good night! Parting is such sweet sorrow / That I shall say good night till it be morrow.. The couplet above comes from Shakespeare's Romeo and Juliet, which is a play, not a poem. But Shakespeare often used rhyming couplets at the end of scenes to signal the ending. Couplets are very common in poetry. Often whole poems are written in couplet form â two lines of rhyming poetry, followed by two more lines with a different rhyme, and so on. Robert Frost, one of America's great poets, wrote many poems using couplets.
