this study was aimed to investigate the bending moment and stress (inner and outer corners) in lshaped biscuit joint made of solid wood, particleboard and medium density fiberboard (mdf). for this purpose, l-shaped joints made of beech and fir, particleboard and mdf by biscuit size numbers of 0 (47×15×3.8 mm), 10 (53×19×3.8mm) and 20 (60×23×3.8mm). bending moment and stress carrying capacity of...

OBJECTIVES To assess if body function, activity, participation, health-related quality of life and lifestyle behavioural factors can predict activity limitation in women with chronic low back pain (CLBP) in primary healthcare (PHC) 2 years later. DESIGN A 2-year prospective longitudinal cohort study within PHC. SETTINGS PHC in southwestern Sweden. PARTICIPANTS The cohort comprised 130 wom...

We consider here pulsatile flow in circular tubes of varying cross-section with permeable walls. The fluid exchange across the wall is accounted for by prescribing the normal velocity of the fluid at the wall. A perturbation analysis has been carried out for low Reynolds number flows and for small amplitudes of oscillation. It has been observed that the magnitude of the wall shear stress and th...

From an analysis of broadband teleseismic Pwaveforms we resolve the complex rupture characteristics of the 17 June 1996, Flores earthquake (Mw 7.9, depth 590 km). This earthquake was unusual because of its large rupture length and the variation in rupture velocity and stress drop. The 20 s rupture propagated westward at 2-3 km/s to a distance of 20-30 km, and eastward at 4 km/s over 75 km. Aver...

In this study, tensile loading experiments are performed on notched steel bars at an average applied strain rate of 1s. Displacement fields are measured across the specimen by coupling digital image correlation (DIC) with imaging using high speed CCD cameras (4796 fps). Results from the experiments indicate the presence of local strain rates ranging from 0.1 to 10s in the notched specimens. The...

background: the interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries. objective: to understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from c...

A large Mw--8.2 earthquake occurred off Shikotan Is., one of the Kurile Is., on October 4, 1994. We inverted 32 body-wave records to determine the rupture pattern using an iterative deconvolution method. The mechanisms of the subevents were allowed to vary during rupture. The source parameters obtained are: the location of the initial break = (43.48øN, 147.40øE); the centroid depth = 56 km; (st...

Earthquakes span a tremendous range of scales, more than 5 orders of magnitude in length. Are earthquakes fundamentally the same across this huge range of scales, or are the great earthquakes somehow different from the small ones? We show that a robust scaling law seen in small earthquakes, with stress drops being independent of earthquake size, indeed holds for great earthquakes as well. The s...
