Chemical engineering and reactor design of a fluidised bed gasifier

A. Al-Farraji2017-01-01ORCA Online Research @Cardiff (Cardiff University)

The design, modelling and optimisation of biofuel thermochemical processes are mainly based on the knowledge of reliable chemical kinetics. The determination of reaction kinetics of biomass at high heating rate still highly depends on the extrapolation of results from kinetic data determined at a comparatively low hea…

Aberrant Autophagy in Macrophages and Astrocytes after HIV Nef or Antiretroviral Treatment: Contribution to the Pathogenesis of HIV-associated Neurocognitive Disorders

Laura Cheney、Tina M. Calderon、Ana María Cuervo 等 4 位作者2017-01-01Open Forum Infectious Diseases

Despite antiretroviral therapy (ART), HIV-associated neurocognitive disorders (HAND) still affect 40–70% of HIV-infected people. The pathogenesis of HAND is multi-factorial and poorly understood. Macroautophagy is a cellular self-digestion process with essential roles in defense against infection, aging, and neurodege…

Responses of reinforced concrete structures under progressive collapse subjected to different loading methods and loading rates

Anh Tuấn Phạm2017-01-01OpenAlex

A research programme on static and dynamic behaviour of reinforced concrete substructures against progressive collapse subjected to different loading rates, loading configurations, as well as structural types, was conducted. Based on numerical analyses, a semi-analytical approach was proposed to predict static respons…

A Machine-Learning Approach to Measuring Tumor pH Using MRI

Joseph B. DeGrandchamp、Julio Cárdenas‐Rodríguez2017-01-01UA Campus Repository (The University of Arizona)

Tumor pH can become an important consideration in diagnosis and choosing an effective therapy. Measuring pH currently requires invasive procedures or has problems with sensitivity. Previous methods for the measurement of pH by MRI are dependent on knowing the concentration of contrast agents or are useful at a limited…

From linear to long-chain branched poly(ethylene terephthalate) – reactive extrusion, rheology and molecular characterization

Matthias Kruse2017-01-01DepositOnce

Poly(ethylene terephthalate) is one of the most widely used polymers in packaging industry, due to its high mechanical strength, chemical resistance, and barrier functions. However, its processing is determined by degradation and low viscosity. In particular, foaming and film blowing is restricted by the linear struct…

Electrostatically Induced Carbon Nanotube Alignment for Polymer Composite Applications

Wesley A. Chapkin2017-01-01Deep Blue (University of Michigan)

We have developed a non-invasive technique utilizing polarized Raman spectroscopy to measure changes in carbon nanotube (CNT) alignment in situ and in real time in a polymer matrix. With this technique, we have confirmed the prediction of faster alignment for CNTs in higher electric fields. Real-time polarized Raman s…

Phase-field models for thin elastic structures: Willmore's energy and topological constraints

Stephan Wojtowytsch2017-01-01Durham e-Theses (Durham University)

In this dissertation, I develop a phase-field approach to minimising a geometric energy functional in the class of connected structures confined to a small container. The functional under consideration is Willmore's energy, which depends on the mean curvature and area measure of a surface and thus allows for a formula…

Parametric Emission Prediction Model in Gas Turbines with Exhaust Gas Recirculation

Vaibhav Prakash2017-01-01Research Repository (Delft University of Technology)

One of the challenges in gas turbines is in the reduction of NOx and CO emissions due to simultaneous dependence on stringent emission norms and subsequent demand for change in operating conditions. To cater the volatile demand of power supply, most of the gas turbines have to be flexible to changing loads. Closer the…

Evaluation of Hypalon® and polyurethane for use in plutonium glovebox environments

Matthew Griffin2017-01-01Texas ScholarWorks (Texas Digital Library)

Nuclear gloveboxes provide a physical barrier between workers and harmful materials. Breaches in gloveboxes may result in lab contamination or even internal uptakes of toxic materials. Such incidents result in both man hours wasted and hazardous working conditions. Therefore, a premium must be set on limiting glovebox…

Computational power of one-dimensional symmetry-protected topological phases

David T. Stephen2017-01-01cIRcle (University of British Columbia)

We consider ground states of quantum spin chains with symmetry-protected topological (SPT) order as resources for measurement-based quantum computation (MBQC). Using tensor network methods, we show that SPT phases protected by a finite abelian on-site symmetry group exhibit uniform computational power. That is, any st…
