Levels and type of atmospheric pollution are currently an issue of debate in thle pathogenesis of asthma. A number of investigators including Drs Magnussen, Jorres and Nowak (September 1993;48:879-81) suggest that heavy traffic exhausts may be related to increased risk of asthmatic symptoms. According to this theory symptoms of asthma and other allergies would be expected to rise in heavily pol...

It has long been known that modular arithmetic often produces interesting numerical patterns. These patterns can be made easier to comprehend and more interesting by rendering them as images with colors associated with numerical values. The example most often cited is Pascal's Triangle , which exhibits the binomial coefficients. If you take the coefficients modulo m for various m, you get diffe...

Texture classification and segmentation have been extensively researched over the last thirty years. Early on the Brodatz album[1] quickly became the de facto standard in which a texture class comprised a set of nonoverlapping sub-images cropped from a single photograph. Later, as the focus shifted to investigating illuminationand pose-invariant algorithms, the CUReT database[3] became popular ...

OBJECTIVE There is little information regarding the isolation of antimicrobial-resistant potentially pathogenic bacteria from water and carpets of mosques worldwide. The objective of the present investigation is to determine the bacteriological quality of water and carpets of mosques in Elkhomes city in Libya. METHODS Potentially pathogenic bacteria were isolated from water samples (n=44) and...

In 1836 Henry Fox Talbot, an inventor of photography, published the results of some experiments in optics that he had previously demonstrated at a British Association meeting in Bristol. "It was very curious to observe that though the grating was greatly out of the focus of the lens...the appearance of the bands was perfectly distinct and well defined...the experiments are communicated in the h...

the art of carpet weaving has undergone changes during the course of history. this ancient art has gradually found its place among other branches of art due to its artistic and consumer characteristics. the art of carpet weaving has heavily influenced other fields like painting for its elegant ornamentation. this paper will elaborate on the widespread relations between persian and italian art d...

In this paper we present a novel 3D scanner to capture the texture characteristics of worn carpets into images of the depth. We first compare our proposed scanner to a Metris scanner previously attempted for this application. Then, we scan the surface of samples from the standard EN1471 using our proposed scanner. We found that our proposed scanner offers additional benefits because it has been...
