In this study, a solvent based chemical upgrading process for coal was applied of biomass. Biomass treated at 320, 350, 380, 400, and 420°C, 2 h with 1-methylnapthlene (1-MN) solvent. Upgraded biomass samples were obtained by removing 1-MN from the using hexane washing approach. A part soluble fraction also in hexane. n-Hexane after recovery (solute) combined to obtain upgraded H/C O/C (UB) clo...

Abstract: In this study, the effect of fuel injection discharge curve and injection pressure simultaneously for upgrading power of heavy duty diesel engine by simulation of combustion process in AVL-Fire software are discussed. Hence, the fuel injection discharge curve was changed from semi-triangular to rectangular which is usual in common rail fuel injection system. Injection pressure with r...

Risk is inherent to the pursuit of opportunity. This paper draws on the recent literature and looks at the risks and opportunities firms and their workers face in the global value chains. First, it examines the sharing mechanisms that firms provide from the national and global perspectives; second, it takes a closer look at the new opportunities and challenges for firms and individuals in the g...

In this report, we present a plan for upgrading the Sequoia 2000 network, a widearea network connecting five UC campuses operating at tens of megabits per second, to gigabit per second speeds. We present our motivation for a gigabit network by describing the new direction of the Sequoia project, now called “Redwood”, and describing the applications that drive our decisions for upgrading the net...

The purpose of the article is to analyze upgrading by looking at the design of fashion garments. To that end, I use the theoretical concept of contextual knowledge to understand the problems faced by firms, and their staff, that want to upgrade through design. Contextual knowledge combines a general knowledge of fashion with the lifeworld that actors use for interpretation of fashion. Lifeworld...
