Likewise, group theory helps predict the changes in physical properties that occur when a material undergoes a phase transition, for example, from a cubic to a tetrahedral crystalline form. An example is ferroelectric materials, where the change from a paraelectric to a ferroelectric state occurs at the Curie temperature and is related to a change from the high-symmetry paraelectric state to the lower symmetry ferroelectic state, accompanied by a so-called soft phonon mode, a vibrational lattice mode that goes to zero frequency at the transition.
What aids in predicting changes of physical traits?
A: group theory

Federal law originates with the Constitution, which gives Congress the power to enact statutes for certain limited purposes like regulating interstate commerce. The United States Code is the official compilation and codification of the general and permanent federal statutes. Many statutes give executive branch agencies the power to create regulations, which are published in the Federal Register and codified into the Code of Federal Regulations. Regulations generally also carry the force of law under the Chevron doctrine. Many lawsuits turn on the meaning of a federal statute or regulation, and judicial interpretations of such meaning carry legal force under the principle of stare decisis.
What is the Federal Register published in?
A: unanswerable

Another approach to brain function is to examine the consequences of damage to specific brain areas. Even though it is protected by the skull and meninges, surrounded by cerebrospinal fluid, and isolated from the bloodstream by the bloodbrain barrier, the delicate nature of the brain makes it vulnerable to numerous diseases and several types of damage. In humans, the effects of strokes and other types of brain damage have been a key source of information about brain function. Because there is no ability to experimentally control the nature of the damage, however, this information is often difficult to interpret. In animal studies, most commonly involving rats, it is possible to use electrodes or locally injected chemicals to produce precise patterns of damage and then examine the consequences for behavior.
The two main structures that protect the brain are what?
A: the skull and meninges

While christian festivals such as corpus christi were church-sanctioned celebrations, Carnival was also a manifestation of European folk culture. In the Christian tradition the fasting is to commemorate the 40 days that Jesus fasted in the desert according to the New Testament and also to reflect on Christian values. As with many other Christian festivals such as Christmas which was originally a pagan midwinter festival, the Christian church has found it easier to turn the pagan Carnaval in a catholic tradition than to eliminate it. Unlike today, carnival in the Middle Ages took not just a few days, but it covered almost the entire period between Christmas and the beginning of Lent. In those two months, several Catholic holidays were seized by the Catholic population as an outlet for their daily frustrations.
Carnival was also a result of what area's folk culture?
A:
European
