BACKGROUND Photodynamic therapy (PDT) using topical delta-aminolevulinic acid (delta-ALA) is an effective treatment for Bowen disease and certain basal cell carcinomas (BCCs), but its place in clinical practice remains to be established. Patients with large and/or multiple lesions of Bowen disease or BCC can represent a considerable therapeutic challenge. We suggest that delta-ALA PDT may be of...

the problem of pole assignment, also known as an eigenvalue assignment, in linear discrete-time periodic systems in discs was solved by a novel method which employs elementary similarity operations. the former methods tried to assign the points inside the unit circle while preserving the stability of the discrete time periodic system. nevertheless, now we can obtain the location of eigenvalues ...

In the first part of these notes we survey results on entropy for smooth systems. We emphasize questions regarding existence and uniqueness of measures of maximal entropy, changes of topological entropy under perturbations, and entropy structures for smooth systems. In the second part of these notes we review topological pressure and equilibrium states for smooth systems. We look at existence a...

Background: Marital satisfaction is one of the most important signs of a favorable relationship between couples.This research aimed to survey the effectiveness of training using Bowen's family therapy approach on marital satisfaction of married women in the city of Aligodarz(In the west of Iran). Methods: This study was aquasi experimental study using a pretest-posttest design with a control g...

Psychologists who study children have emphasized family processes that influence children's psychological well-being and subsequent development, but gerontologists have rarely considered the impact of the family as system in adulthood. Drawing on family systems theories, we show how between- family, within-family, and within-individual differences emerge from family interactions in adulthood. S...
