Shear thickening is a widespread phenomenon in suspension flow that, despite sustained study, is still the subject of much debate. The longstanding view that shear thickening is due to hydrodynamic clusters has been challenged by recent theory and simulations suggesting that contact forces dominate, not only in discontinuous, but also in continuous shear thickening. Here, we settle this dispute...

The use of elastomer additives to solve the problems in oil well cementing has been investigated in recent years by several research groups in the petroleum industry. This study includes the laboratory examination of the effect of elastomer additives on the physical properties of heavy-weight oil well cement. In the research process, a candidate well is selected and the properties of the cement...

A process of dry heating alkaline powder containing whey protein (WP) and lactose is used to produce microparticles that can trap large amounts water thus be in many food applications as a thickening agent. The objective this study was optimise the yield particles formed amount they well minimise duration. parameters studied were contents WP lactose, pH, storage time at activity (aw) powder, te...

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 study aimed to describe the effectiveness of switching the anti-TNFα agent when an acceptable clinical response has not been obtained with the first anti-TNFα agent in patients with uveitis in VKH syndrome. Patients diagnosed with VKH syndrome being evaluated from the uveitis unit of a single tertiary hospital from January 1, 2000, to October 30, 2015. Patients who presented uveitis with an...

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 ...

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...
