This work addresses the determination of cohesive laws in Mode I and tangential–longitudinal (TL) crack propagation system Fagus Sylvatica L. species is one ever-growing most widely used hardwood Europe for engineered timber products. Double Cantilever Beam (DCB) tests are performed. The strain energy release rate (GI) derived from R-curves by applying Compliance-Based Method (CBBM), which has ...

Microscopic methods were used to investigate the unique collar structure of the gram-negative sulfate-reducing bacterium, strain DCB-1. Polar cell growth apparently occurred from the collar. When the daughter cell was approximately equal in length to the mother cell and the collar was thus centrally located, cell division occurred within the collar region. Division was by a novel mechanism whic...

Subchronic inhalation toxicity of p-dichlorobenzene (p-DCB) was examined by exposing BDF1 mice and F344 rats of both sexes (6 h/d and 5 d/wk) to inhalation of 25, 55, 120, 270 or 600 ppm (v/v) p-DCB vapor for 13 wk. The exposure to p-DCB vapor retarded the growth rate in the male mice, and induced hepatotoxicity in the mice and rats of both sexes and renal and hematological toxicity in the male...

The pathogenesis of lupus nephritis is mainly attributable to a complex interaction between the innate and adaptive immune systems, including T and B cell function abnormalities. In addition to autoantibody production and immune complex deposition, Th1 and Th17 cytokines may play key roles in the development and progression of lupus nephritis. Acute onset of severe lupus nephritis remains a cha...

Peripheral arterial disease, particularly critical limb ischemia, is an area with urgent need for optimized therapies because, to date, vascular interventions often have limited life spans. In spite of initial encouraging technical success after femoropopliteal percutaneous transluminal angioplasty or stenting, postprocedural restenosis remains the major problem. The challenging idea behind the...

A prospective, single-blind, randomized, multicenter trial (entry dates not mentioned). After successful predilation with a high-pressure balloon of stenotic lesions in failing hemodialysis arteriovenous fistulas (AVFs), 152 patients underwent treatment drug-coated (DCB) and 148 standard (SB) at 29 international sites. The 6-month target lesion patency was significantly greater the treated DCB ...

Fairness in a data center by Mikkel Hagen University of New Hampshire, December, 2012 Existing data centers utilize several networking technologies in order to handle the performance requirements of different workloads. Maintaining diverse networking technologies increases complexity and is not cost effective. This results in the current trend to converge all traffic into a single networking fa...

Background and Purpose—Neuronal Na/Ca exchanger plays a relevant role in maintaining intracellular Ca and Na levels under physiological and pathological conditions. However, the role of this exchanger in excitotoxicity and ischemia-induced neuronal injury is still controversial and has never been studied in the same neuronal subtypes. Methods—We investigated the effects of bepridil and 39,49-di...

This paper deals with the implementation of an efficient Arbitrary Lagrangian Eulerian (ALE) formulation for the three dimensional finite element modeling of mode I self-similar dynamic fracture process. Contrary to the remeshing technique, the presented algorithm can continuously advance the crack with the one mesh topology. The uncoupled approach is employed to treat the equations. So, each t...
