Objective: The optimal treatment of severe monolateral asymptomatic carotid artery stenosis (SMACS) in patients undergoing coronary artery bypass grafting (CABG) is still controversial. Materials and methods: This study is based on the in-hospital and mid-term (.5 years) clinical results of a cohort of 139 consecutive CABG patients with SMACS operated at our Institution between January 1989 and...

The arbitrary Lagrangian Eulerian formulation is derived for the residual distribution method on moving meshes. The system of Euler equations is discretized on moving meshes and in case of deforming meshes a geometrical source term has to be taken into account. A conservative linearization guarantees the conservation property of the discretized equations. From the geometric conservation law we ...

A series DC motor must be represented by a nonlinear model when nonlinearities such as magnetic saturation are considered. To provide effective control, nonlinearities and uncertainties in the model must be taken into account in the control design. In this paper, the recursive design method is applied to generate nonlinear control, nonlinear PI control, and robust control, and these controls ar...

Several promising approaches for hexahedral mesh generation work as follows: Given a prescribed quadrilateral surface mesh they first build the combinatorial dual of the hexahedral mesh. This dual mesh is converted into the primal hexahedral mesh, and finally embedded and smoothed into the given domain. Two such approaches, the modified whisker weaving algorithm by Folwell and Mitchell, as well...

Previous studies on Toxoplasma gondii population structure, based essentially on multilocus restriction fragment length polymorphism analysis or on multilocus enzyme electrophoresis, indicated that T. gondii comprises three clonal lineages. These studies showed a weak polymorphism of the markers (2–4 alleles by locus). In this study, we used eight microsatellite markers to type 84 independent i...

In this work, computational methods were utilized to optimize the field produced by the transverse electromagnetic (TEM) resonator in the presence of the human head at 8 Tesla. Optimization was achieved through the use of the classical finite difference time domain (FDTD) method and a TEM resonator loaded with an anatomically detailed human head model with a resolution of 2 mm 2 mm 2 mm. The he...

Two hundred and forty pigs of 56 ± 3 days of age were used to investigate the effects of sex (barrows; gilts), boar sire (DD, Danish Duroc; ND ✕ LW, Dutch Duroc ✕ Large White ; P ✕ LW, Pietrain ✕ Large White) and slaughter age (160; 175 days) on performance and carcass and meat quality. Treatments were arranged factorially (2 ✕ 3 ✕ 2) and there were four replicates (five pigs per replicate) per...

In order to study left ventricular filling in hypertrophic cardiomyopathy, left ventricular cineangiograms of 20 patients were digitised frame by frame and compared with those of 10 normal subjects. Peak left ventricular filling rate was 770+/-260 ml s-1 (mean+/-1 standard deviation), not significantly different from normal. Mitral valve opening was delayed, occurring 140+/-40 ms after time of ...

A preoperative weight loss of 8 % is a prerequisite to undergo bariatric surgery (BS) in Denmark. The aim of the present study was to evaluate the efficacy of a 7- or an 11-week low-energy diet (LCD) for achieving preoperative target weight before BS. A total of thirty obese patients (BMI 46·0 (sd 4·4) kg/m(2)) followed an LCD (Cambridge Weight Plan(®), 4184 kJ/d (1000 kcal/d)) for 7 or 11 week...
