Commercial Scale Quantification of Lignin
Abstract: Lignin, an aromatic biopolymer, in the terrestrial lignocellulosic biomass constitutes the single largest and sustainable source of biofuels and biochemicals. The recalcitrant nature of lignin is a hindrance to its chemical or biochemical conversion. Moreover, its insolubility in water too is a major challenge in its quantification which is a necessary step prior to and after its conversion. Though there are celebrated quantification methods like the classical Klason lignin method …

DESIGNING OF A LEAN ASSEMBLY LINE FOR NATIONAL HEATER COMPANY AT AL-RUSAYL
Abstract: Most industrial sectors are concerned with reducing wastes activities; therefore they mostly use Lean manufacturing technology as the best solution to accomplish their aim. These non-added value wastes could be unnecessary motion, inadequate processing, excessive transportation, defects, waiting, unnecessary inventory and overproduction. A survey was implemented on both Rusayl Industry Area Company and National Heater Industries Company L.L.C for this study purpose as those two companies are compatible with this …

Study of Shear Strength Behaviour of Soil With Kaolinite Mixture
Abstract: An experimental testing program was undertaken for evaluating the effect of kaolinite on the strength properties of locally available sand and soil. Strength depends principally upon the content of (1) water, (2) clastic materials and (3) plastic materials. Soils are primarily of two types (1) cohesionless soils in which the strength this produced mainly by the friction of clastic particles against one another, and (2) cohesive soils in which the …

Fault Location in Two Phase Traction System
Abstract: Owing to the installation of autotransformers at regular intervals along the line, distance protection relays cannot be used with the aim of locating ground faults in 2×25 kV railway power supply systems. The reason is that the ratio between impedance and distance to the fault point is not linear in these electrification systems, unlike in 1×25 kV power systems. Therefore, the location of ground faults represents a complicated task in …
