Abstract:

David Perlov y José Luis Guerin convergen en lo esencial al pensar el cine no en relación con lo industrial sino en relación con lo artesanal: el cine como un forma de escritura. Pero no es este el único punto de encuentro entre las obras cinematográficas de estos dos directores pudiendo advertirse entre ambas otros puntos de confluencia. En este artículo trataremos, pues, de examinar la obra de sendos cineastas atendiendo a sus paralelismos, esto es rastrear aquellos elementos o rasgos del cine de Perlov que reaparecen en el cine de Guerin, así como de dilucidar la naturaleza de dicha relació

Resumo Com base no estudo do processo criador dos diários cinematográficos de David Perlov, e detendo-se sobretudo na sua experiência brasileira, o artigo analisa como a escritura fílmica do cineasta faz das imagens da memória uma superfície de dupla face – como a banda de Moebius – que passa do interior ao exterior, do dentro ao fora, da experiência subjetiva à experiência social e histórica.

Nesses diários, realizados entre os anos 1970 e 2000, a errância, o trauma, o exílio e o luto são figuras de uma enunciação subjetiva e de uma narrativa em trânsito constante, para as quais o deslocamento, não sendo apenas geográfico

Abstract:

In this paper, two types of fixed point theorems are employed to study the solvability of nonlocal problem for implicit fuzzy fractional differential systems under Caputo gH-fractional differentiability in the framework of generalized metric spaces. First of all, we extend Krasnoselskii?s fixed point theorem to the vector version in the generalized metric space of fuzzy numbers. Under the Lipschitz conditions, we use Perov?s fixed point theorem to prove the global existence of the unique mild fuzzy solution in both types (i) and (ii). When the nonlinearity terms are not Lipschitz, we combine P

Background: Obstetric violence could be defined as the dehumanized treatment or abuse of health professionals towards the body or reproductive process of women. Some practices associated with obstetric violence have been routinely standardized and do not include the woman in decision making. This type of violence has consequences for the health of both the mother and the baby and that of the professionals who practice or observed it. Methods: A questionnaire consisting of 33 items that measured perception through a Likert scale was developed. Some sociodemographic variables were collected. The

We study the existence of solutions for nonlinear first order impulsive systems with nonlocal initial conditions. Our approach relies in the fixed point principles of Schauder and Perov, combined with a vector approach that uses matrices that converge to zero. We prove existence and uniqueness results for these systems. Some examples are presented to illustrate the theory.

The results showed that supplementation of the reactors with polymers, either natural or synthetic, enhanced the granulation in comparison to control reactors (without the addition of polymers). A greater granulation was, however, obtained with chitosan compared to that with Percol 763. Chitosan yielded a granulation rate as high as 56 m/d compared to 35 m/d Percol 763.

As an application, we investigate the solution of a semilinear operator system in Banach space.
