Background and Aim: Considering the increasing use of antibiotics in root canal therapy and the possible effects of intracanal medicaments on the bond strength of composite restorations, the aim of this study was to evaluate the effect of triple antibiotic paste (TAP) on shear bond strength of three types of composite resins to dentin. Materials and Methods: In this in-vitro, experimental st...

BACKGROUND Few studies have examined associations of multi-faceted demographic, health and lifestyle factors with long-term change in grip strength performance across the adult lifespan. The aim of this study was to examine the associations of risk factors in specific parts of the adult lifespan (e.g. in early midlife, in late midlife and in old adulthood) separately for women and men. METHOD...

The purpose of the study was to determine the relation between quintiles of muscular strength after adjustment for age and body weight, and excessive body fat (EBF) and excessive abdominal fat (EAF) when controlling for cardiorespiratory fitness (CRF) and other potential confounders. A two-phased cross-sectional and longitudinal study was conducted assessing the prevalence and incidence of EBF ...

PURPOSE The purpose is to study the age trajectory of hand-grip strength after the age of 45 years. METHODS In this study, we use data from three large nationwide population-based surveys of Danes aged 45 to 102 years with a total of 8342 participants with grip-strength measurements and up to 4 years of follow-up. Grip strength was measured by using a portable hand dynamometer. RESULTS Grip...

Our knowledge of the age and sex associated changes in strength during childhood and adolescence is relatively limited compared to other physiological parameters. However, those studies available on the age and sex associated change in strength are relatively consistent, especially for the lower limbs. Caution must be taken when transferring this knowledge to other muscle joints as the developm...

The present study experimentally investigates the fatigue strength of longitudinally loaded welded joints in beam structures made ultra-high-strength steel. Hereby, effects different manufacturing methods and welding preparations on crack initiation locations box I section beams are evaluated. Specifically, experimental tests carried out these prepared with manual automatic welding, subjected t...

To investigate the gradual failure of high-density polyethylene (HDPE) geomembrane as a result of long-term corrosion, four dynamic corrosion tests were conducted at different temperatures and durations. By combining tension and puncture tests, we systematically studied the variation law of tension and puncture properties of the HDPE geomembrane under different corrosion conditions. Results sho...

Cold roll forming (CRF) is a bending process where the bending occurs gradually in severalforming steps from an undeformed strip to a finished profile. The process is very interesting for thesheet metal industry due to the high speed in which the profile can be produced. High strength steelhas, in recent years, become more common in CRF. These materials have advantages but also<...
