BACKGROUND AND AIM: Ameloblastic fibro-odontoma (AFO) is a rare, mixed odontogenic tumor that usually occurs in children and young adults with no gender predominance. Posterior mandibular region is usually involved and a painless swelling is the most common clinical feature.CASE REPORT: We here report a case of AFO in a 12-year-old girl with a complaint of a painful expansive lesion in the righ...

Let d ≥ 1, and let α be an expansive Z-action by continuous automorphisms of a compact abelian group X with completely positive entropy. Then the group ∆α(X) of homoclinic points of α is countable and dense in X, and the restriction of α to the α-invariant subgroup ∆α(X) is a Z-action by automorphisms of ∆α(X). By duality, there exists a Z-action α∗ by automorphisms of the compact abelian group...

OBJECTIVE This article examines how workers supported by outplacement services engage with an occupational transition through problem solving and learning. PARTICIPANTS The participants were 23 mid-life redundant white collar workers with at least eight years in their sector, organization or occupation. The selected interviewees either participated in training to broaden their professional co...

The National School Feeding Program (PNAE for its acronym in Portuguese) is one of the largest food policies world, partially covering daily needs 44 billion students per year. In 2009, Law No. 11,947 established that at least 30% total financial transfer PNAE was used purchase foodstuff directly from family farming left-wing government Lula. practice, rules allow public policy managers to choo...

We study expansive invertible onesided cellular automata (i.e., expansive automorphisms of onesided full shifts) and find severe dynamical and arithmetic constraints which provide partial answers to questions raised by M. Nasu [N2]. We employ the images and bilateral dimension groups, measure multipliers, and constructive combinatorial characterizations for two classes of cellular automata.

In this paper, we show that if a transitive set Λ is C-stably expansive, then Λ admits a dominated splitting.

Learning about narrative and spectatorship in film studies lends itself to active forms of learning. This paper reports on the participatory development between film studies and learning design of an activity called Director's Cut. A class of 250 undergraduate students created their own film sequence applying their understandings of genre, screenwriting and editing in order to manipulate how fi...

We investigate striped structures of stable and unstable sets of expansive homeomorphisms and continuum-wise expansive homeomorphisms. The following theorem is proved: if f : X → X is an expansive homeomorphism of a compact metric space X with dimX > 0, then the decompositions {W (x) | x ∈ X} and {W (x) | x ∈ X} of X into stable and unstable sets of f respectively are uncountable, and moreover ...
