Technical thermoplastic materials (e.g., PEEK, PPA and POM) are widely used for tribological applications combined with different filler systems glass- or carbon fibres) because of their excellent mechanical properties. The friction wear behaviour thermoplastics can be specifically improved by solid lubrication such as graphite, PTFE MoS2. Besides these systems, others WoS2 MnS becoming scienti...

this study determined the effects of carboxymethylcellulose gel on rheological properties of bread dough, quality parameters for barbari bread (volume, specific volume, hardness and softness of texture, cooking loss, water activity), and sensory properties of fresh bread. hydrocolloid carboxymethylcellulose (cmc) was added at 0.5%, 1%, 1.5% w/w (flour basis) to wheat flour. a farinograph was us...

This article reports the effective usage of redmud(RM) an industrial waste ,as a  novel filler in polymer matrix. The composite has been fabricated with redmud as secondary reinforcement in banana fiber reinforced polyester (BFRP) using compression molding technique. The mechanical properties such as tensile, flexural and impact strength have been studied for different fiber weight percentage, ...

for a given riemannian manifold (m,g),it is an interesting question to study the existence of a conformal diffemorphism (also called as a conformal transformation) f : m ! m such that the metric g? = fg has one of the following properties: (i)(m; g?) has constant scalar curvature. (ii)(m; g?) is an einstein manifold.
