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 tiny fraction consisted of way more phenolic substances (mainly consisting of p-coumaric and you can ferulic acid) and had highest lignin posts and anti-oxidant capabilities versus bran-derived lignin small fraction.
80 On the internet Electric current Mainly based Prognosis of Stator Problems for the Squirrel Cage Induction Motors
In the present paper, four electric energy centered methods to get acquainted with digital flaws toward stator from induction automobiles (IM) are used and you may compared. The analysis tries to expand the application of the latest several site structures diagnosis strategy. An eccentricity indicator was presented to boost the application of the new Areas Vector Method strategy. Most of the fault symptoms was verified and lots of someone else revised, concur with the technical literatures and typed results. A beneficial tri-stage 3hp squirrel-cage I will be, especially altered to determine more fault profile, is employed to possess validation motives.
79 Optimization of Import Molding Process by Implementation of Online Monitoring Strategies for Digital Packages
Quality of the shaped bundles was firmly determined by the process variables of import molding. To get to a better package top quality and you can a reliable import molding processes, it is important to learn new dictate of the procedure details for the package top quality. So it performs will comprehend the dating amongst the procedure variables, and pick brand new optimum procedure details with the transfer molding processes to have shorter voids and cord brush. To achieve this, an excellent DoE was carried out for techniques optimization and a good regression analysis is performed. A clinical means is actually illustrated to create habits and this allow an quote of the amount of voids and cord brush. Recognition studies try held to confirm the fresh new design together with abilities is actually showed.
78 Studies Management Demands inside Traditional Procurement Program
Regarding the structure business, venture professionals are conveyor off project knowledge that’s, usually, maybe not handled safely for usage in the future strategies. As the design projects is temporary and unique, project participants are prepared to end up being hired after a job was completed. Ergo, worst handling of training across construction programs will lead to good substantial amount of knowledge losses; the fresh overlooking from which might be detrimental to enterprise performance. This problem is much more popular within the programs undertaken from old-fashioned procurement system, as this system doesn’t bonuses endeavor people having consolidation. For this reason, problems occur involving the construction and design phase in accordance with the worst management of knowledge between these levels. It papers is designed to stress the difficulties of your own education management one is available into the old-fashioned procurement system. Expert interview was in fact conducted and you can challenges were understood and analysed from the brand new Interpretive Architectural Modeling (ISM) method to help you sumong her or him. A few identified trick pressures will be the People of an organization and you can Education Management Formula. A familiarity with the problems in addition to their relationships can assist endeavor director and stakeholders having a much better knowledge of the value of real information management.
