These raw materials contain large amounts of polysaccharides, in particular hemicelluloses, celluloses, and lignins, which if efficiently extracted, can be utilised for the development of a range of added value products with potential applications in agriculture and food packaging sectors. The aim of this study was to characterise fractions extracted from sorghum bran and stalk with regards to their physicochemical properties that could determine their applicability as food-packaging materials. A sequential alkaline extraction was applied for the isolation of cellulosic, hemicellulosic and lignin fractions from sorghum stalk and bran. Lignin content, phenolic content and antioxidant capacity were also investigated in the case of the lignin fraction. Thermal analysis using differential scanning calorimetry (DSC) and X-Ray Diffraction (XRD) revealed that the glass transition temperature (Tg) of cellulose fraction of the stalk was
5%. In terms of hemicellulose, the Tg value of stalk was slightly lower compared to bran at amorphous state (
2%). It is evident that hemicelluloses generally showed a lower thermal stability compared to cellulose, probably due to their lack of crystallinity. Additionally, bran had higher arabinose-to-xylose ratio (0.82) than the stalk, a fact that indicated its low crystallinity. Furthermore, lignin fraction had Tg value of
11%). Stalk-derived lignin small fraction contained a great deal more phenolic ingredients (mostly including p-coumaric and you will ferulic acid) along with high lignin content and you can anti-oxidant ability compared to bran-derived lignin tiny fraction.
80 Online Household current Built Analysis away from Stator Faults to the Squirrel Crate Induction Cars
In the present paper, four electric current mainly based remedies for become familiar with electric faults into stator regarding induction motors (IM) are used and you may compared. The research tries to stretch using the newest several resource structures analysis technique. A keen eccentricity sign was presented to help the application of new Parks Vector Method technique. Most of the fault indicators is verified and several other people changed, buy into the technical literatures and blogged efficiency. A beneficial tri-stage 3hp squirrel cage I will be, especially altered to ascertain some other fault accounts, is used having validation motives.
79 Optimization of the Transfer Molding Processes of the Implementation of On the internet Monitoring Tips for Electronic Bundles
Quality of the new molded bundles is highly dependent on the process variables of import molding. To reach a much better plan top quality and you will a reliable import molding process, it is important to understand the influence of your own procedure details with the plan top quality. Which really works is designed to comprehend the relationships within process variables, in order to choose the fresh new greatest techniques details towards import molding procedure in order to achieve shorter voids and you can wire brush. To do so, a beneficial DoE is actually conducted for procedure optimization and you can an excellent regression investigation is completed. A clinical strategy is portrayed to generate activities and that enable an quote of the number of voids and you will cable sweep. Validation tests is presented to verify new model additionally the abilities was demonstrated.
78 Knowledge Management Challenges in this Conventional Procurement System
In the framework world, venture professionals was conveyor regarding endeavor studies that is, tend to, not handled safely press the site for usage in future programs. Because the construction plans are brief and you may book, project people are prepared to feel employed just after a job are complete. Thus, worst management of knowledge all over build strategies often lead to a substantial amount of real information losings; the newest overlooking from which would be harmful to enterprise abilities. This matter is much more common into the systems undertaken from antique procurement system, as this program doesn’t bonuses investment players having combination. Ergo, issues can be found amongst the build and you may construction levels in line with the poor management of degree ranging from both of these stages. It papers aims to emphasize the problems of one’s degree management you to is available within the old-fashioned procurement program. Specialist interview was used and you can pressures had been known and you will analysed by the the Interpretive Architectural Model (ISM) strategy to sumong them. One or two identified key demands would be the Society of an organisation and Knowledge Management Principles. An understanding of the problems in addition to their relationships will assist endeavor director and stakeholders getting a better knowledge of the benefits of knowledge administration.
