Upgrading of Pyrolysis Bio-oil: A Review

The increase in the population of the planet and the rapid economic growth and, consequently, the high consumption of energy has created many environmental problems in the globe. Due to these reasons and the lack of renewability of these fossil fuels, there has been a steep trend towards the production of renewable fuels from natural sources, one of which is the production of energy from biomas...

Fermentative Upgrading of Xylose

Chemical pulp mills such as Kraft, soda, or sulfite mills are current examples of biorefineries that can convert lignocellulosic biomass into energy, pulp or cellulose derivatives, and tall oil. While existing viscose pulps use a hemicellulose extraction to generate soluble sugars for ethanol production, in general there still exists a large potential for other more profitable applications of t...

Upgrading Bottleneck Constrained Forests

We study bottleneck constrained network upgrading problems. We are given an edge weighted graph G = (V; E) where node v 2 V can be upgraded at a cost of c(v). This upgrade reduces the delay of each link emanating from v. The goal is to nd a minimum cost set of nodes to be upgraded so that the resulting network has a good performance. The performance is measured by the bottleneck weight of a con...

Upgrading Narrow Gauge Standards

When the railways were nationalized between 1906 and 1907, the skeleton of the nationwide trunk rail network was nearly completed, as mandated in the Railway Construction Act of 1892. At the end of 1907, nationalized railway lines in operation totalled 7,165 km. Construction continued and 2,677 km of line were added by the end of 1919. In addition to active line expansion, the first decade afte...
