Non-sewered sanitation is currently dependant upon pit latrine emptying, the safety of which compromised by high costs faecal sludge transport to centralised treatment facilities. Transport in turn hindered complex rheology sludge. This study therefore characterised compressional fresh faeces and modelled implications for passive (gravity) or mechanical (forced) solid/liquid separation. informs...

Gravity data inversion is one of the important steps in the interpretation of practical gravity data. The inversion result can be obtained by minimization of the Tikhonov objective function. The determination of an optimal regularization parameter is highly important in the gravity data inversion. In this work, an attempt was made to use the active constrain balancing (ACB) method to select the...

1. Universidade Federal do Rio de Janeiro, Rio de Janeiro (RJ) Brasil. 2. Universidade Federal de Ciências da Saúde de Porto Alegre, Porto Alegre (RS) Brasil. A 63-year-old female patient presented with a 1-year history of recurrent polyarthritis and a 3-month history of dry cough. Her laboratory test results were normal. Physical examination revealed deformity in both ears, with inflammatory s...

Background. In previous studies comparing regional 20MT1 (201Tl) and 18fluorodeoxyglucose (FDG) activity in patients with chronic coronary artery disease and left ventricular dysfunction, we hypothesized that regions with mild-to-moderate reduction in FDG activity and regions with mild-to-moderate irreversible 2`Tl defects after 3to 4-hour redistribution represent viable myocardium. In the pres...

The pathology of arteriosclerosis has been much studied in recent years: but the clinical aspects have had little attention. A small book on diagnosis written by Parkinson in 1898 had more space devoted to examination of the arteries than Saville's " Clinical Medicine" of 1939, which has six times the number of, pages. Even Cowdry's symposium on arteriosclerosis does not say much on the clinica...

the effect of weak shear thickening and shear thinning on the stability of the taylor-couette flow is explored for a carreau-bird fluid in the narrow-gap limit. the galerkin projection method is used to derive a low-order dynamical system from the conservation of mass and momentum equations. in comparison with the newtonian system, the present equations include additional nonlinear coupling in ...

in the present work properties of rossby and inertia gravity waves are investigated based on proper orthogonal decomposition (pod) functions. the pod functions are constructed using analytical, experimental or numerical data recorded as snapshots. the pod basis can be carried out to make a reduced order model by galerkin projection of governing equations onto these functions. in this paper, the...

INTRODUCTION Inflammatory diseases of the maxillary sinus favour the thickening of the sinus mucosa. Therefore, it might be possible to establish a radiological, pathological threshold of mucosal thickening. Furthermore, there is an association between common anatomic variants of the nose and maxillary mucosal thickening. AIM To define the pathological thickening of maxillary sinus mucosa and...

OBJECTIVES Heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) have a higher predisposition to select for VISA with thickened cell walls upon vancomycin exposure, but the pharmacodynamic relationship of this occurrence with clinical doses is unknown. This study investigates the impact of clinical vancomycin dose simulations on cell wall thickness (CWT) and the emergence of resis...
