The fiber was ground in a disc mill and grinding characteristics were evaluated by calculating work index (0.206 kW h/kg) as well as Bond s (0.065 kW h/kg), Kick s (0.047 kW h/kg) and Rittinger s (0.022 kW h/kg) constants. The reduction in the particle size from 1127 to 550 lm resulted in increased hydration properties (water holding, water retention, swelling capacity), which may be due to increase in theoretical surface area and total pore volume as well as structural modification. Beyond 550 lm, the hydration properties were found to decrease with decrease in particle size during grinding. The fat absorption capacity was found to increase with decrease in particle size. The study of microstructures revealed that the grinding operation resulted in rupture of honey comb physical structure fiber matrix and resulting in flat ribbon type structure, thereby providing increased surface area for water and fat absorption Thu, 17 Feb 2005 00:00:00 GMT http://pucir.inflibnet.ac.in:8080/jspui/handle/123456789/1089 2005-02-17T00:00:00Z http://pucir.inflibnet.ac.in:8080/jspui/handle/123456789/1081 Title: Shellac as a multifunctional biopolymer: A review on properties, applications and future potential Authors: Kumar, Saurav Abstract: Shellac is a physically refined form of lac resin, a natural biopolymer of animal origin obtained from tiny insects feeding on the sap of specific host trees. Shellac, in its basic form, is a polyester macromolecule composed of inter and intra esters of polyhydroxy aliphatic and sesquiterpene acids. It has been used in several industries for ages due to its exceptional properties such as film-forming, adhering, bonding, thermoplasticity, water-resistance and easy solubility in spirit and aqueous alkali solvents. From the beginning of the 21st century, due to increasing demand for natural products, a paradigm shift in the scope and applications of shellac has been witnessed, especially in green electronics, 3D printing, stealth technology, intelligent sensors, food and pharmaceutical industries. Shellac offers enormous potential for greener technologies as a natural and environmentally friendly material. This review provides an insight into the lac in detail, covering various forms of the lac, structure, properties, different applications of shellac and its future potential. This article would benefit the researchers involved in shellac research and others looking for natural and greener alternatives to synthetic polymers in various applications.

This study extends big data analytics adoption research by examining the effects of system characteristics on the attitude of managers towards the usage of big data analytics systems. A research model has been proposed in this study based on an extensive review of literature pertaining to the Technology Acceptance Model, with further validation by a survey of 150 big data analytics users. Results of this survey confirm that characteristics of the big data analytics system have significant direct and indirect effects on belief in the benefits of big data analytics systems and perceived usefulness, attitude and adoption. Moreover, there are mediation effects that exist among the system characteristics, benefits of big data analytics systems, perceived usefulness and the attitude towards using big data analytics system. This study expands the existing body of knowledge on the adoption of big data analytics systems, and benefits big data analytics providers and vendors while helping in the formulation of their business models.
