In the technological world, retrofitting of damaged structures has been emerged as an essential need and a common technique. For indent retrofitting, fiber reinforced polymer composites are used. Due to its beneficial properties, they used in massive work fields. Fiber polymers holds high strength weight ratio. area civil engineering, FRP habituated strengthen existing RC structures. extended e...

An experimental and numerical study has been carried out to investigate the heat transfer by natural convection radiation in a two dimensional annulus enclosure filled with porous media (glass beads) between horizontal concentric cylinders. The outer cylinders are of (100, 82 and70mm) outside diameters inner cylinder 27 mm diameter (or without) annular fins attached it. Under steady state condi...

Mandarin speech data Across Taiwan (MAT) is a project initiated by members of the Association for Computational Linguistics and Chinese Language Processing (ACLCLP) to collect speech data through public telephone networks in Taiwan. Totally over 7000 Taiwanese individuals have provided speech data. The results were released as a series of MAT speech databases to the research community in Taiwan...

This paper presents an algorithm for generating the Medial Axis Transform (MAT) of 3D objects with free form boundaries that are obtained by extrusion along a line or revolution about an axis. The algorithm proposed uses the exact representation of the part and generates an approximate rational spline description (to within a defined tolerance) of the MAT. The algorithm uses the 2D MAT of the p...

A methodology based on mathematical morphology is proposed for efficient recognition of two-dimensional (2D) objects or shapes. It is based on the introduction a shape descriptor called the morphological autocorrelation transform (MAT). The MAT of an image is composed of a family of geometrical correlation functions (GCFs) which define its morphological covariance in a specific direction. The M...

Phototrophic microbial mats are among the most diverse ecosystems in nature. These systems undergo daily cycles in redox potential caused by variations in light energy input and metabolic interactions among the microbial species. In this work, solid electrodes with controlled potentials were placed under mats to study the electron transfer processes between the electrode and the microbial mat. ...

We cloned the pheromone precursor genes of Podospora anserina in order to elucidate their role in the biology of this fungus. The mfp gene encodes a 24-amino-acid polypeptide finished by the CAAX motif, characteristic of fungal lipopeptide pheromone precursors similar to the a-factor precursor of Saccharomyces cerevisiae. The mfm gene encodes a 221-amino-acid polypeptide, which is related to th...

BACKGROUND Crohn's disease (CD) is associated with complex pathogenic pathways involving defects in apoptosis mechanisms. Recently, mesenteric adipose tissue (MAT) has been associated with CD ethiopathology, since adipose thickening is detected close to the affected intestinal area. However, the potential role of altered apoptosis in MAT of CD has not been addressed. AIMS To evaluate apoptosi...

The purpose of this review is to characterize the preoperative assessment of meniscal allograft transplantation (MAT) candidates, to detail MAT surgical techniques, and to evaluate current clinical outcome data on MAT. The MAT candidate is typically less than 50 years old and has a history of knee injury, previous meniscus surgery, and persistent pain. Physical exam generally reveals knee pain ...

In solfataric fields in southwestern Iceland, neutral and sulfide-rich hot springs are characterized by thick bacterial mats at 60 to 80 degrees C that are white or yellow from precipitated sulfur (sulfur mats). In low-sulfide hot springs in the same area, grey or pink streamers are formed at 80 to 90 degrees C, and a Chloroflexus mat is formed at 65 to 70 degrees C. We have studied the microbi...
