1. Caracterização litoestrutural e parametrização geomecânica das superfícies de ruptura em taludes na Mina de N4E Carajás / PA
The Carajás Mineral Province has been discovered in the 60s and mining activities began in the 80s, which has been increasing significantly up to the present day. It is the most important unit of VALE Company, related to the exploitation of iron ore. The N4E mine has been chosen because it is the main mine of the Carajás Mineral Complex and it presents the

2. Cosmic ray Ground Level Enhancements (GLEs) of october 28, 2003 and january 20, 2005: a simple comparison
A evolução do aumento de raios cósmicos na superfície terrestre (GLE) no dia 28 de outubro de 2003 (evento Halloween) e outro evento subseqüente no dia 20 de janeiro de 2005 (um evento grande em fase de declínio da atividade solar) foram examinados. O GLE no dia 28 de outubro foi notado pequeno, porém a diminuição Forbush e o índice Dst no dia segu

3. Estudo das correlações entre a atividade solar e processos atmosfericos
As correlações da atividade solar com o clima foram investigadas em regiões de baixas latitudes da América do Sul. Em algumas regiões da Terra, os ciclos de 11 e 22 anos (anti)correlacionam, por exemplo, com a variação dos níveis de chuvas. O mecanismo responsável por esta correlação ainda não é conhecido. Nós estudamos dados atualizados das va

4. Avaliação cefalometrica do perfil tegumentar e esqueletico inicial e final de tratamento ortodontico
Was accomplished a study in 114 telerradiography of the head in lateral norm, of 57 Brazilian individuais, white, with Class 11, division 1 malocclusion (An.gle), submitted to orthodontic treatment according to the Tweed philosophy, with the purpose of evaluating the alterations to levei of the bony and soft-profile . The results demonstrated that among the

5. The human homologue of Saccharomyces cerevisiae Gle1p is required for poly(A)+ RNA export
The mechanism of mRNA export is a complex issue central to cellular physiology. We characterized previously yeast Gle1p, a protein with a leucine-rich (LR) nuclear export sequence (NES) that is essential for poly(A)+ RNA export in Saccharomyces cerevisiae. To characterize elements of the vertebrate mRNA export pathway, we identified a human homologue of yeas

6. GLE2, a Saccharomyces cerevisiae homologue of the Schizosaccharomyces pombe export factor RAE1, is required for nuclear pore complex structure and function.
To identify and characterize novel factors required for nuclear transport, a genetic screen was conducted in the yeast Saccharomyces cerevisiae. Mutations that were lethal in combination with a null allele of the gene encoding the nucleoporin Nup100p were isolated using a colony-sectoring assay. Three complementation groups of gle (for GLFG lethal) mutants w

7. Two yeast nuclear pore complex proteins involved in mRNA export form a cytoplasmically oriented subcomplex
We sublocalized the yeast nucleoporin Nup82 to the cytoplasmic side of the nuclear pore complex (NPC) by immunoelectron microscopy. Moreover, by in vitro binding assays we showed that Nup82 interacts with the C-terminal region of Nup159, a yeast nucleoporin that previously was also localized to the cytoplasmic side of the NPC. Hence, the two nucleoporins, Nu

8. Primary structure and expression of a gamete lytic enzyme in Chlamydomonas reinhardtii: similarity of functional domains to matrix metalloproteases.
A gamete lytic enzyme (GLE) of Chlamydomonas reinhardtii is a zinc metalloprotease and mediates digestion of the cell walls of the two mating-type gametes during mating as a necessary prelude to cell fusion. The nucleotide sequence analysis of a cDNA revealed that GLE is synthesized in a preproenzyme form, a 638-amino acid polypeptide (Mr, 69,824) with a 28-

9. The Nuclear Pore Complex and the DEAD Box Protein Rat8p/Dbp5p Have Nonessential Features Which Appear To Facilitate mRNA Export following Heat Shock
Nuclear pore complexes (NPCs) play an essential role in RNA export. Nucleoporins required for mRNA export in Saccharomyces cerevisiae are found in the Nup84p and Nup82p subcomplexes of the NPC. The Nup82p subcomplex contains Nup82p, Rat7p/Nup159p, Nsp1p, Gle1p/Rss1p, and Rip1p/Nup42p and is found only on the cytoplasmic face of NPCs. Both Rat7p and Gle1p con

10. The Integral Membrane Protein Snl1p Is Genetically Linked to Yeast Nuclear Pore Complex Function
Integral membrane proteins are predicted to play key roles in the biogenesis and function of nuclear pore complexes (NPCs). Revealing how the transport apparatus is assembled will be critical for understanding the mechanism of nucleocytoplasmic transport. We observed that expression of the carboxyl-terminal 200 amino acids of the nucleoporin Nup116p had no e

11. Yeast heat shock mRNAs are exported through a distinct pathway defined by Rip1p
We reported previously that heat or ethanol shock in Saccharomyces cerevisiae leads to nuclear retention of most poly(A)+ RNA but heat shock mRNAs (encoding Hsp70 proteins Ssa1p and Ssa4p) are efficiently exported in a process that is independent of the small GTPase Ran/Gsp1p, which is essential for most nucleocytoplasmic transport. To gain further insights

12. The yeast nucleoporin Rip1p contributes to multiple export pathways with no essential role for its FG-repeat region
The FG-repeat domain of the yeast Rip1 protein (Rip1p) was identified initially as a possible target for the nuclear export signal (NES) of the HIV-1 Rev protein in a yeast two-hybrid assay. Rip1p is inessential, associated with nuclear pore complexes, and structurally related to the FG-nucleoporin family of pore proteins. It contributes to HIV-1 Rev-mediate
