The electrocardiogram of the question shows prolonged QRS and QTc segments.

متن کاملSnow White and the Seven Dwarfs
“Snow White”’s historical credentials are well known: as the Disney studio’s first feature-length film, it marked a significant turning point for Walt Disney himself, for the Disney studio, for the art of animation, and to some extent for American films in general.

Photographs and videos from brilliant colour...
متن کاملSnow White: Provably Secure Proofs of Stake
Decentralized cryptocurrencies have pushed deployments of distributed consensus to more stringent environments than ever before. Most existing protocols rely on proofs-of-work which require expensive computational puzzles to enforce, imprecisely speaking, “one vote per unit of computation”. The enormous amount of energy wasted by these protocols has been a topic of central debate, and well-know...
متن کاملWhite on green: under-snow microbial processes and trace gas fluxes through snow, Niwot Ridge, Colorado Front Range
The importance of snow and related cryospheric processes as an ecological factor has been recognized since at least the beginning of the twentieth century. Even today, however, many observations remain anecdotal. The research to date on cold-lands ecosystems results in scientists being unable to evaluate to what extent changes in the cryosphere will be characterized by abrupt changes in local a...
