Especially in the field of sewage pumps, design radial impellers focuses not only on maximum efficiency but also functionality terms susceptibility to clogging by fibrous media. In general, is significantly lower than that clear water impellers. These are designed with a low number blades ensure media can be pumped. This paper describes methodology an optimisation for impeller. The carried out ...

  Solitary Fibrous Tumors (SFTs) are rare primary pleural neoplasms which have recently been reported in extra-thoracic sites. In this report, solitary fibrous tumor arising in an intra-thoracic goiter with no evidence of cervical mass in a 74-year-old obese man who was found to have a large superior mediastinal mass with tracheal deviation on Chest X-Ray is presented.

MR images shows an atherosclerotic plaque (arrow) of a mouse ascending aorta, which is confirmed by histology (B, HE staining, 1.25×). P=plaque. (C) Magnification of the same microscopic image of B, demonstrating the formation of a typical atherosclerotic plaque (P) with a ruptured fibrous cap (arrow), intraplaque fibrin deposition and hemorrhage, as well as foam cells accumulation. M=media. Fi...

Transmittance and reflectance from spruce wood and bovine ligamentum nuchae as two different fibrous media are examined by time-of-flight spectroscopy for varying source detector separations and several orientations of the fibers in the sample. The anisotropic diffusion theory is used to obtain the absorption coefficient and the diffusion coefficients parallel and perpendicular to the fibers. T...

an occlusive, diffuse, generalized lesion in medium and small-sized arteries, with particular involvement of the heart, skin, gastrointestinal tract, kidneys, pancreas, and liver. It showed a fibrous thickening of the intima; the internal lamina elastica, the media, and the adventitia remained unchanged. A pathogenic interpretation of the vascular lesions is attempted, and their asynchronism in...

The acoustic absorption of granular aerogel layers with a granule sizes in the range 2 to 40 μm is dominated by narrow-banded, high regions low-frequency and reduced values at higher frequencies. In this paper, we investigate possibility developing new, noise reduction materials layering aerogels traditional porous sound absorbing such as glass fibers. behavior layered configurations predicted ...

There is a general lack of publications on the acoustical and related non-acoustical properties nanofibrous media. This work attempts to contribute this gap highlight problems associated with acoustic non-acoustic characterisation these materials. The work, presumably for first time, applies Biot- Darcy-type mathematical models explain observed behaviours nanofibres. It identifies theoretical g...
