Anatomy of contemporary GSM cellphone hardware Harald Welte April 16‚ 2010 Abstract Billions of cell phones are being used every day by an almost equally large number of users. The majority of those phones are built according to the GSM protocol specifications and interoperate with GSM networks of hundreds of carriers. Despite being an openly published international standard‚ the architecture of GSM networks and its associated protocols are only known to a relatively small group of R&D engineers

Pig and Human Anatomy In today’s standard anatomy classes- among other science classes- pigs are the most commonly dissected mammal because they have the most similar anatomy to a human. They have the same organs and many of the same muscles pertaining to similar human functions. When dissecting pigs it is important to remember the basic directional points. For example‚ median means to the middle‚ lateral means to the sides‚ dorsal is the belly-side‚ etc. It is also important to have lab safety
