in this paper, g-dual function-valued frames in l2(0;1) are in-troduced. we can achieve more reconstruction formulas to ob-tain signals in l2(0;1) by applying g-dual function-valued framesin l2(0;1).
in the present research, damage mechanisms during room temperature uniaxial tensile testing of two different modern high strength dual phase steels,dp780 and dp980, were studied. detailed microstructural characterization of the strained and sectioned samples was performed by scanning electron microscopy (sem). the results revealed that interface decohesion, especially at the triple junctions of...
background: despite the advantages of dual peer mentoring, there are a few reports of implementing and evaluating such programs for medical students. this study aimed at exploring the perceptions of mentors and mentees about the dual peer mentoring program for the first year undergraduate medical students of tehran university of medical sciences. methods: this qualitative study was conducted...
The aim of this study was to investigate the effectiveness of motor and cognitive dual-task training on dynamic balance of elderly women. For this purpose, 27 old women (aged 60 -82 years) from the old people center of Birjand city were selected randomly and divided into 3 groupd based on their TUG scores. The groups comprised of cognitive dual-task training, motor dual-task training and contro...
This paper is concerned with some methods that attempt to provide simultaneous representation of dual relationships, such as ties of membership that connect persons and groups, or connections between organizations and agendas. We focus on vector space and lattice representations, and on techniques for simplifying the structure of dual networks. We demonstrate some fundamental similarities among...
Objectives: The main goal of this study was to investigate the impact of difficulty level of postural task on dual task performance in young and older adults. Methods & Materials: 20 young (20-30 years) and 20 elderly (65-70 years) participants were selected by non-probable sampling method. Postural tasks (standing with parallel feet on the hard and foam surface) and cognitive task retrieved...
background: a few studies have investigated the effect of the activation mode of adhesive systems on bond strength of fi ber posts to root canal dentin. this study investigated the push-out bond strengths of a glass fi ber post to different root canal regions with the use of two adhesives with light- and dual-cure polymerization modes. materials and methods: in this in vitro study, 40 maxillary...
Background. Parkinson’s disease (PD) is characterized by motor and non-motor symptoms that affect patients’ functional performances, especially while performing dual tasks which is a critical factor in connection with everyday living. There are many controversies about the benefits. Objectives. This study assessed the efficacy of motor and cognitive dual-task training programs for improving of ...
Indirect esthetic restorations have recently gained popularity, and choosing suitable cement is an important concern in this regard. A wide variety of resin cements with different curing models:(chemical, light, dual), have been introduced to the profession, and among them the dual systems are claimed to be able to continue polymerization after stopping the light. In order to study and compare ...
