the research compares 5-12 year old children of addicted fathers with those of non-addicted fathers. this experiment was carried out on one hundred families of the addict, in comparison to another one hundred non-addicted families. these children have not been subjects for social scientists and health experts because of the following facts: 1) they live with their parents, 2) they are not crimi...

The human cognitive system has various functions to enhance performance in tasks requiring responses to stimuli. When potentially occurring stimuli are known, we can establish selective attention sets and ignore task-irrelevant events while attending task-relevant ones. When the stimulation is temporally structured, we can rely on constant temporal relationships between stimulus events to prepa...

Recent developments in cancer therapy have resulted in increases in treatment success rates and survival. One of thebasic goals of such therapy is improving patient quality of life. Chemotherapy protocols for solid or hematologicalmalignancies-most of which include multiple agents-negatively impact patient quality of life. Additionally, there havebeen developments in supportive care, which seek...

objectives: since support for family caregivers is crucial in providing care for elderly, this study was conducted to examine the effects of participation in support groups on alzheimer’s family caregivers’ strain and spiritual wellbeing. materials and methods & materials: in this semi-experimental study, 32 accessible family caregivers of elderly patients with alzheimer who had at least one ye...

This report defines the rank complement of a diagonalizable matrix (i.e. a matrix which can be brought to a diagonal form by means of a change of basis) as the interchange of the range and the null space. Given a diagonalizable matrix A there is in general no unique matrix Ac which has a range equal to the null space of A and a null space equal to the range of A, only matrices of full rank have...

ing this paper new factorization techniques for computation of the Operational Space Mass Matrix (A) and its inverse (A-l) are developed. Starting with a new factorization of the inverse of mass matrix (M-l) in the form of Schur Complement as M-l = G’ %)TsI-lB, where d and 8 are block tridlagonal matrices and G is a tridiagonal matrix, similar factorization for A and A-i are derived. Specifical...
