Microtubule-based motor proteins assemble and reorganize acentrosomal mitotic and meiotic spindles in animal cells. The functions of motor proteins in acentrosomal plant spindles are unknown. The cellulosic cell wall and relative small size of most plant cells precludes accurate detection of the spatial distribution of motors in mitosis. Large cell size and absence of a cellulosic cell wall in ...

The agricultural industry is one of the main economic contributors in developing countries, especially tropical regions. Extensive land clearing has led to severe erosion within watersheds, which increases vulnerability water catchments natural disasters, such as floods. Cellulosic fibers, jute, sisal, kenaf, hemp, and coir, are gaining increasing worldwide attention for their potential applica...

The adsorption of polysaccharide guar gum and starch additives and their interactions with cellulosic fiber and fines, as well as soluble and colloidal carbohydrates, present in wood pulp suspensions were investigated by employing HPLC and spectrophotometry. A unique phenomenon, i.e. carbohydrate uptake or ‘substraction’, was observed to occur in a variety of cellulosic systems [whole pulp, was...

This work was sparked by the reported identification of man-made cellulosic fibers (rayon/viscose) in the marine environment as a major fraction of plastic litter by Fourier transform infrared (FT-IR) transmission spectroscopy and library search. To assess the plausibility of such findings, both natural and man-made fibers were examined using FT-IR spectroscopy. Spectra acquired by transmission...

In the last few years, an increase in interest has been given to the use of cellulose fibers as alternatives for conventional reinforcements in composites. The development of commercially viable environmentally friendly and healthy materials based on natural resources is on the rise. In this sense, cellulosic fibers as reinforcements for cement mortar composites constitute a very interesting op...

Recent advances in understanding the structure of cellulose are used as the basis for analyzing the structural changes that occur in pulp fibers during papermaking, particularly in the drying stage. These changes are responsible for the degradation of papermaking properties, and they must be reversed during recycling if the maximum papermaking potential of the virgin fibers is to be recovered. ...

in the present study, development of new asbestos-free brake pad using lingo-cellulosic fibers and nano aluminum oxide particles was investigated. variable factors were the type of lignocellulosic materials (jute, bagass and rice husk) and the size of aluminum particles (nano and micron). these newly formulated brake pads have been tested under the grey cast iron disc. friction coefficient and ...
