Sludge management accounts for approximately 60% of the total wastewater treatment plant expenditure and laws for sludge disposal are becoming increasingly stringent, therefore much consideration is required when designing a solids handling process. A membrane thickening aerobic digestion process integrates a controlled aerobic digestion process with pre-thickening waste activated sludge using ...

We have studied a sample of 24 edge-on interacting galaxies and compared them to edge-on isolated galaxies, to investigate the effects of tidal interaction on disk thickening. We found that the ratio h/z0 of the radial exponential scalelength h to the scale height z0 is about twice smaller for interacting galaxies. This is found to be due both to a thickening of the plane, and to a radial strip...

the results of batch settling tests (bst) are used to investigate settling behavior of solids suspension, which contribute to sizing thickeners. conventional methods in analyzing bst on the basis of visual and graphical procedures lead to sub-optimally sized and selected thickeners. a computational approach based on quantitative analysis of bst can be beneficial. about 300 settling experiments ...

background: in some studies, the involvement of dangerous psychological and behavioral factors in etiology and physiotherapy of vascular disturbances have been shown. in other studies, the relationship between the personality type and increase in cardiovascular disease has been demonstrated. the type d personality is defined as having two characteristics of negative affect and social inhibition...

Cylindrical cavitation bubbles, capable of generating extreme strain rates, are experimentally and theoretically studied in shear-thickening suspensions. Starting from the limit between continuous discontinuous shear thickening regimes, bubbles deform increasingly with increasing solid volume fraction until replaced by cavitation-induced fractures.

BACKGROUND Haemodialysis vascular access dysfunction is currently a huge clinical problem. Although arteriovenous (AV) fistulae are the preferred mode of dialysis access, they have significant problems with both early (failure to mature) and late fistula failure. Both are characterized radiologically as a stenosis of the venous segment. Despite the magnitude of the clinical problem, the exact p...

In an attempt to provide a better understanding of our finding that regions with contracting left ventricular myofibers need not develop a significant transmural systolic wall thickening gradient, the analytic approach of Costa et al. was applied to the four-dimensional dynamic data obtained 1 and 8 wk after surgical implantation of transmural radiopaque beads in the lateral equatorial left ven...

PURPOSE To investigate the healing pattern of the mucous membrane after tooth extraction necessitated by periodontal disease in the maxillary sinus. METHODS One hundred and three patients with 119 maxillary sinuses were investigated. Before implant placement, cone-beam computed tomography (CT) scanning was performed. The causes of extraction, the time elapsed since extraction, smoking, period...

Thickening compositions of a new composition for printing mixed fabrics based on cotton and nitron fibers have been developed. The influence the components dampening rheological properties depending their concentration was studied. Established development thickening its physico-chemical properties.

Brief coronary artery occlusion (CAO) and reperfusion induce myocardial stunning and late preconditioning. Postsystolic wall thickening (PSWT) also develops with CAO and reperfusion. However, the time course of PSWT during stunning and the regional function pattern of the preconditioned myocardium remain unknown. The goal of this study was to investigate the evolution of PSWT during myocardial ...
