A modified smoothed particle hydrodynamic (MSPH) computational technique was utilized to simulate molten particle motion and infiltration speed on multi-scale analysis levels. The radial velocity and velocity gradient of molten alumina, iron infiltration in the TiC product and solidification rate, were predicted during centrifugal self-propagating high-temperature synthesis (SHS) simulation, wh...

PURPOSE Arteriovenous fistula non-maturation because of a peri-anastomotic venous stenosis is currently a huge clinical problem for which there are no effective therapies. METHODS In an attempt to further define the cellular pathways involved in this process we have assessed the pattern and intensity of macrophage infiltration at different time points in a pig model of AVF stenosis. RESULTS...

We present a method for the detection and quantification of white matter infiltration from human brain tumours based on Diffusion Tensor Imaging (DTI). Since white matter destruction alters the local diffusion properties, DTI has the potential to sensitively detect tumour infiltration and to quantify the degree thereof. Here, we consider three tumour patients with gliomas, two with and one with...

flood spreading stations were constructed in iran with different objectives such as groundwater recharge and vegetation recovery. accumulation of sediment can be a major problem in flood spreading stations. according to generally accepted theories, floods and salt pollution can reduce gradually the infiltration rate. in order to investigate this issue, 13 flood spreading stations were selected ...

lymphocytic infiltration of jessner-kanof is a chronic, benign t cell infiltration disorder of exposed skin with unknown etiology. in some instances, these lesions are induced or aggravated by light exposure. in this case report, we are going to describe an interesting occupationally related skin disease, jessner's disease, after several years working with computer. on the basis of literature r...

This work probes the influence of wetting on pressure infiltration. Pressure/saturation curves for the infiltration of packed F-1000 angular alumina particle preforms by liquid Cu-Al and Sn-Al alloys are measured using an instrumented high-temperature pressure infiltration apparatus. These are ceramic-metal systems in which the contact angle is documented to vary significantly with alloying, fr...

use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems isn’t an accurate approach because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. in this study the infiltration parameters were evaluated in real conditions of a center pivot system. for this purpose a single ring with ...

This work identifies the critical factors when developing a polymer brush vapor phase infiltration process, while also demonstrating use of novel pyridines for area selective purposes.
