statement of problem: in some clinical situations, repair of composite restorations is treatment of choice. improving the bond strength between one new and old composite usually requires increased surface roughness to promote mechanical interlocking since chemical bonding might not be adequate. similarly, the treatment of a laboratory fabricated resin composite restoration involves the same pro...

Participants of the study were 120 English as a Foreign Language (EFL) learners who were selected based on their scores on a sample copy of the Oxford Placement Test (OPT). T...

This paper compares the effectiveness of random and t-way combinatorial testing, where t = 2, 3, 4, for a grid computer network simulator. Previous investigations of random vs. combinatorial testing have reached conflicting results, with some showing more effective fault detection for combinatorial testing and others finding no significant difference between the two methods. In this paper, thes...

The valid confirmation of a positive change (improvement) in a patient's health status due to intervention has been at the core of medicine and rehabilitation since their very inception as clinicians always aspired to ensure that treating their patients had led to successful outcomes both in acute and chronic conditions. However what is change: either improvement or worsening (aggravation), is ...

background nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. this study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. methods fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. objective a...
