Synchrotron X-ray microtomography has been utilized for the in situ observation of fatigue crack opening/closure during load cycles. High-resolution phase contrast imaging technique has enabled the reconstruction of clear crack images together with…

An adaptive arbitrary Lagrangian-Eulerian formulation is developed to compute the material flow and the temperature evolution during the three phases of the friction stir welding (FSW) process. It follows a splitting approach: after the calculations…
-
In the paper the results of a wide range of experiments on friction stir welding (FSW) of aluminium alloys are reported. In particular, the AA6082-T6 butt joints fatigue resistance was investigated by varying the most relevant process parameters. In…

BACKGROUND: Bacterial adherence to the stent surfaces, concomitant colonization, and possible stent blockage are the main complications after the use of biliary stents. The present study was assigned to investigate bacteriologic and morphologic…
-
Biomaterials in the peritoneal cavity disrupt the physiology of the host and may cause bacterial translocation. The current study was performed to determine whether biomaterials exacerbate intraabdominal infections. Adult male rats were divided into…
-
Economic analysis of law usually proceeds under the assumptions of neo-classical economics. But empirical evidence gives much reason to doubt these assumptions; people exhibit bounded rationality, bounded self-interest, and bounded willpower. This…
-
Experiments in articular cartilage have shown highly nonlinear stress-strain curves under finite deformations, nonlinear tension-compression response as well as intrinsic viscous effects of the proteoglycan matrix and the collagen fibers. A biphasic…
-
We investigate the dependence of fiber brightness on three-dimensional fiber orientation when imaging biopolymer networks with confocal reflection microscopy (CRM) and confocal fluorescence microscopy (CFM). We compare image data of fluorescently…
-
Friction stir welding (FSW) and friction stir processing (FSP) produce a fine grained 'nugget' region. The microstructural refinement and uniformity depends on processing parameters and tool design. During post-processing at high temperatures,…
-
Abnormal grain growth can be a critical issue during the post-processing heat treatment of friction stir welded or processed aluminum alloys. Various theories have been proposed to elucidate the origin of this behavior. This viewpoint paper…

The influence of suspended particulate matter, benzo(e) pyrene, benzo(e) pyrene and benzo(a) anthracene concentration on pulmonary lung functions ie, residual volume, total lung capacity, residual volume/total lung capacity, forced residual capacity…
-
Cyclic stretch has been demonstrated to induce proliferative and secretory activities by cultured arterial endothelial and smooth muscle cells, cellular processes that contribute to the development of intimal hyperplasia. A model of an end-to-side…

This new method for boxing a corrected cast impression for a distal extension removable partial denture improves the procedure. The framework with its impression is seated on the remainder of the cast after anatomic ridges have been removed and…
-
We give a brief review of hysteresis in viscoelastic polymers. The efforts surveyed range from phenomenological to molecular modelling with applications involving recent efforts on elastomers to biotissue.
-
Stimulus-active polymers can vary their shapes (configuration or dimension) or produce mechanical power in response to external stimuli such as heat, electricity, light, magnetic field, and water. In the past decade, many breakthroughs have been…
-
BACKGROUND: Natural rubber latex sensitization is caused by proteins from the latex of Hevea brasiliensis, the Brazilian rubber tree. Alternative non-cross-reactive latex rubber sources are needed for the manufacture of nonallergenic medical devices…
-
Absorption, distribution, metabolism and excretion were studied in rats following a single oral administration of N-cyclohexyl-2-benzothiazyl sulfenamide (CBS) at a dose of 250 mg/kg. About 65% and 24% of the dose were excreted into urine and feces,…
-
A total of 10 tubing materials (butyl-, rubber-, latex-, polyethylene-, Perbunan-, PVC-, silicone-, Teflon-, Tygon- and Vitontubes), which are sold for laboratory use, was tested for their sorption capacity. Different concentrations (0.03-8…

A case-control study of bladder cancer was conducted in five United States rubber and tyre companies to determine if there were high-risk jobs and work areas within the industry. The study included 220 male cases of bladder cancer, of whom 107 were…
