4. Estrategias de utilização de registroa de representação semiotica na resolução de problemas matematicos / Strategies using semiotic representations registers in problem solving
Based on references of Semiotic Representations Registers Theory by Raymond Duval (1993), this research intends to analise the usage that high school students do use Semiotic Representation registers in order to solve math problems. According to the Author, the access to math objects is made through these representation registers, because such objects aren t

12. Possible Loss of Length Conservation and Reciprocity during Recombination or Conversion in Tandem Arrays
Recombination or conversion between arrays of repeated sequences need not be conservative for length because two single strands of DNA from one chromatid may form heteroduplexes in different registers on the other participating duplex. This can cause an overall change in repeat number. Loss of length conservation is equally possible whether models of recombi
