Relationship between coping and subjective well-being of elderly from the interior of the Brazilian Northeast

The objective of this study was to verify how the coping strategies, applied to health problems of the elderly, are related to the levels of Subjective Well-Being (SWB) in a cluster sample of 381 elderly people with an average age of 71.50 years (SD = 8.0), mostly female (73.4 %). The following instruments were used: Mini-Mental State Examination, Problem Coping Mode Scale, Satisfaction with Li...

Perception of toothache in adults from state capitals and interior cities within the Brazilian geographic regions

BACKGROUND Studies emphasizing toothache in adulthood are scarce in Brazil. A greater understanding of both the prevalence and the self-perception of pain among individuals in this age group (35 to 44 years old) is important, especially considering that this is an economically active population. To describe reports of oral pain and oral pain-related aspects in from Brazilian state capitals and ...

Interior design

The mitochondrion is the 'power house' of the cell. The internal structure of the mitochondrion — in particular, the shape of the infoldings of the inner membrane (cristae) — has long been debated. Now, three-dimensional tomographic reconstructions like the ones above are resolving the controversy. At top left, a slice through a rat liver mitochondrion is reconstructed, showing 44 cristae (yell...

Deformation and strength anisotropy of calcareous slates under Brazilian tests

Rock anisotropy plays an important role in engineering behavior of rocks. Slates are anisotropic rocks which have long been used for gable roof, floor tiles, borrow materials, and other purposes. The slates studied in this research are calcareous and have a porphyro-lepidoblastic texture. To determine the role of the anisotropy on the tensile strength and fracture pattern, two variables includi...
