Epoxidation of oleic acid and cottonseed oil was conducted in a semibatch reactor with in-situ-formed percarboxylic acid (peracetic acid or perpropionic acid), using hydrogen peroxide as an oxidizing agent and carboxylic acid (acetic acid or propionic acid) as oxygen carriers. Amberlite IR-120 was implemented as the catalyst. The system was comprised of a loop reactor, where the mixture was pumped through a single-mode cavity in which microwave irradiation was introduced. A heat exchanger was integrated into the system to replace microwave heating, to compare the results obtained via microwave heating versus conventional heating. The catalyst loading effect was studied, as well as the influence of microwave irradiation and the implementation of the SpinChem rotating bed reactor (RBR), in hopes of decreasing the influence of the internal mass transfer. The application of microwave irradiation results in an improvement of the reaction yield in the absence of a catalyst., Bio4Energy

Models that accurately capture all segments of the population are necessary in order to design effective policies and new technologies to ensure efficient and stable operations of cities. The current sociology literature has a rich foundation in characterizing the demographics of static population distributions, however, these characterizations fail to account for the reality of dynamic movement. Though there has been recent work in developing models of human mobility, they in turn do not capture demographic differences in the populations of cities. In this work we present a computational approach to reformulating segregation metrics to incorporate dynamic movement patterns and also quantify the effects of introducing demographics into a mobility model. In coupling two fields that are inherently connected but not established as so, we must very carefully consider our experimental set up. The first part of this work deals with understanding our data and its limitations at fine granularities and explicitly measuring segregation metrics at various scales to design a study that will elucidate meaningful aspects of segregation. In the second part of this work we reformulate traditional segregation metrics using topological properties of origin destination networks as input. These measures are flexible in considering many locations that individuals visit and therefore more accurately capture the environments of individuals that traditional segregation literature seeks to characterize. We utilize two rank-based mobility models that implicitly incorporate geographic properties of population distributions to understand the effects of residential segregation on mobility patterns and examine the effect of demographic considerations on model accuracy. In summary, this thesis will focus on synthesizing the rich body of work on static characterizations of socioeconomic structure in c, by Suma Desu., S.M.

Floodplain forests are linear forest systems, occupying the lower areas of river catchments. Their boundaries correspond with the areas disturbed by river flooding and they generally have shallow water tables. The ecology of floodplain forests is closely linked to the dynamic physical processes associated with flooding. The regeneration of floodplain forest species is particularly dependent on periodic floods and sediment deposition. River engineering practices and wholesale clearance of natural floodplain forests for agriculture or forestry have made them very rare in Europe, with about 10 % of the original amount remaining, mostly in the larger river systems of Eastern Europe. There are new opportunities for restoration of floodplain forests provided by some areas of European legislation such as the European Habitats Directive, Water Framework Directive and Floods Directive and by a new interest in soft engineering approaches to flood management. However, many constraints remain, often related to competing economic incentives for the use of floodplain land.

Los conceptos de Dios, la carne y el otro pertenecen sin lugar a dudas, y de manera ejemplar, al campo de la fenomenología contemporánea, pero encuentran en el Corpus de la filosofía patrística y medieval no solamente un lugar para enraizarse, sino también para renovarse. Cabe anotar que la propuesta de la presente obra busca ser retomada y transformada por otros. Coedición con la Universidad Católica de Colombia.

El Círculo Carmesí es una organización secreta que extorsiona y asesina en el Londres de principios del s. XX. Su ingenio diabólico y su eficacia desafían y atemorizan a la sociedad. Así, el lector se va internando en un intrincado laberinto de sospechas que se desplazan sobre los diferentes personajes a medida que cada uno de ellos va demostrando su inocencia. El resultado es una rápida carrera de inteligencia entre novelista y lector, que podrá resolver o no el sorprendente rompecabezas pero que no quedará nunca defraudado.
