Consolidation and creep are two types of time-dependent deformation clay soil. However, the soil presents probabilistic behaviours when spatial variability is considered. The Monte–Carlo method used to sample anisotropic random fields that mapped into two-dimensional finite element models (RFEM) analyse influences on parameters generated by a spectral representation (SRM) describe consolidation...

Segmentation of lung tissue from CT images is a challenging task in computer aided diagnosis systems. In this work, a patient-specific, automated model based approach to segment lung is proposed. Patient specific shape knowledge is obtained by preprocessing the same patient’s stack of lung CT slices. The algorithm divides the patient's stack into many groups and the first ‘n’ slices with maximu...

excessive production and stockpile of scrap tires cause some environmental and sanitary risks throughout the world. to manage these materials, possible use of soil-tire mixtures has been recently propounded in civil engineering projects. a few studies previously have been conducted to evaluate behavior of clay-tire mixtures, while swelling properties, consolidation and settlement characteristic...

When a mass of saturated clay is heated, as in the case of host soils surrounding nuclear waste disposals at great depth, the thermal expansion of the constituents generates excess pore pressures. The mass of clay is submitted to gradients of pore pressure and temperature, to hydraulic and thermal flows, and to changes in its mechanical properties. In this work, some of these aspects were exper...

background accurate diagnosis of tuberculosis in infants is important. there are a few studies around tuberculosis in infancy in the literature. objectives this study defines the clinical and radiological features of tuberculosis in infants less than one year of age. materials and methods the medical records were reviewed for all infants aging 12 months or less with diagnosis of tuberculosis at...

The ability to simultaneously measure both biofilm thickness and the mass transfer coefficient of an inert tracer through it provides a powerful method to study biofilm development. In this communication previously published data has been collated to interpret global trends in biofilm structure during the transition towards steady-state. It appears that sudden changes in biofilm structure (dire...
