Effects of prebiotic fibre diets on rat mucosal intestinal and systemic immunity and in vitro mechanistic analysis of anti-inflammatory effects of lactobacillus strains on rat and human intestinal epithelial cells
(2012-08-01)Probiotics and prebiotics are emerging household terms, whose claimed health benefits share commonality. Their attributed health benefits include the production or induction of short chain fatty acids, maintaining bowel ... -
Predicting mutation score using source code and test suite metrics
(2012-09-01)Mutation testing has traditionally been used to evaluate the effectiveness of test suites and provide con dence in the testing process. Mutation testing involves the creation of many versions of a program each with a single ... -
Impact of environmental conditions on expression levels of resistance-nodulation-division (RND) efflux pumps and outer membrane porins in Acinetobacter baumannii
(2012-09-01)Acinetobacter baumannii is a globally emerging Gram-negative pathogen accounting for a variety of nosocomial conditions, including pneumonia, meningitis, peritonitis, urinary tract infections and, in particular, wound ... -
Computational and laboratory investigations of a model of blood droplet flight for forensic applications
(2012-09-01)We present a three-dimensional, forward model of blood droplets in ight. The proposed model is based on a set of ordinary di erential equations (ODEs) incorporating viscous drag and gravitational forces. We validate the ... -
Synthesis of internal amide bond short interfering RNAs (siRNAs) and investigation of their gene silencing properties
(2012-10-01)Cancer is a leading cause of death worldwide, accounting for around 13% of all death [1]. Traditional cancer therapeutics usually require careful selection of one or more intervention, such as surgery, radiotherapy, and ... -
Expression of Arabidopsis thaliana cellulose synthase proteins and associated proteins in a Spodoptera frugiperda cell line
(2012-10-01)Understanding how cellulose synthesis occurs is key to understanding the formation of the plant cell wall. This understanding could also be key to modifying cellulose production to permit more efficient extraction of ... -
Self-healing solutions for LTE evolved packet core
(2012-10-01)The 3GPP Long Term Evolution (LTE) is considered as a dominant future cellular wireless technology in terms of performance and user experience. With technological advancement of the wireless networks, dependencies and ... -
A molecular characterization of agonists that bind to Hco-UNC-49, a GABA-gated chloride channel from Haemonchus contortus
(2012-11-01)Haemonchus contortus is a blood feeding parasitic nematode infecting ruminants causing anemia and poor health at great economic cost. The ability to pharmaceutically control infection has been challenged by the rapid ... -
Exploring entities in text with descriptive non-photorealistic rendering
(2012-12-01)We present a novel approach to text visualization called descriptive non-photorealistic rendering which exploits the inherent spatial and abstract dimensions in text documents to integrate 3D non-photorealistic rendering ... -
Convection in a differentially heated rotating spherical shell of Boussinesq fluid with radiative forcing
(2012-12-01)In this study we investigate the flow of a Boussinesq fluid contained in a rotating, differentially heated spherical shell. Previous work, on the spherical shell of Boussinesq fluid, differentially heated the shell by ... -
Using Rabin-Karp fingerprints and LevelDB for faster searches
(2012-12-01)This thesis represents the results of a study into using fingerprints generated according to the Rabin-Karp Algorithm, and a database LevelDB to achieve Text Search times below GREP, which is a standard command-line UNIX ... -
Reliable peer-to peer multicast streaming
(2013-01-01)P2P is increasingly gaining its popularity for streaming multimedia contents. The architecture of streaming has shifted from traditional client server architecture to P2P architecture. Although it is scalable and robust ... -
Vector occluders: an empirical approximation for rendering global illumination effects in real-time
(2013-02-01)Precomputation has been previously used as a means to get global illumination effects in real-time on consumer hardware of the day. Our work uses Sloan’s 2002 PRT method as a starting point, and builds on it with two new ... -
Exploring Entities in Text with Descriptive Non-photorealistic Rendering
(IEEE, 2013-03)We present a novel approach to text visualization called descriptive non-photorealistic rendering which exploits the inherent spatial and abstract dimensions in text documents to integrate 3D non-photorealistic rendering ... -
Design and implementation of the crypto-assistant: an eclipse plugin for usable password-based column level encryption based on hiberate and jasypt
(2013-03-01)The lack of encryption of data at rest or in motion is one of the top 10 database vulnerabilities according to team SHATTER [72]. In the quest to improve the security landscape, we identify an opportunity area: two tools ... -
Analysis of the volatile organic compounds produced by the decomposition of pig carcasses and human remains
(2013-03-01)Complex processes of decomposition produce a variety of chemicals as soft tissues and their component parts are degraded. Among others, these decomposition by-products include volatile organic compounds (VOCs) responsible ... -
The synthesis and in vitro evaluation of siRNAs modified at the backbone with a novel triazole-based internucleotide linkage and abasic alkyl-chain linkages of varying length
(2013-04-01)For over a decade, the use of double-stranded short interfering RNAs (siRNAs) to silence the expression of genes associated with disease at the translational level has gained much attention. Using a highly conserved ... -
Critical InfoVis: Exploring the Politics of Visualization
(ACM, 2013-04-27)As information visualization is increasingly used to raise awareness about social issues, difficult questions arise about the power of visualization. So far the research community has not given sufficient thought to how ... -
