13. Analise de parametros de tenacidade ao fraturamento de concretos obtidos em ensaios de flexão de vigas
Concrete is a composite that behaves inelasticaly, with failure characterized by softening. Crack in this kind of material is said to be cohesive. The development of an inelastic process zone ahead of the crack front as well as the formation of the cohesive interface, at laboratory level, are directly infIuenced by the specimen Size. The effect of the specim

14. Process analytical technology case study: Part II. Development and validation of quantitative near-infrared calibrations in support of a process analytical technology application for real-time release
This article is the second of a series of articles detailing the development of near-infrared (NIR) methods for solid dosage-form analysis. Experiments were conducted at the Duquesne University Center for Pharmaceutical Technology to demonstrate a method for developing and validating NIR models for the analysis of active pharmaceutical ingredient (API) conte

15. The Use of Mixture Models to Detect Effects of Major Genes on Quantitative Characters in a Plant Breeding Experiment
An analysis based on Elston's model of mixed major locus and polygenic inheritance is extended to include populations of progeny testing such as F(3), B(1s) and B(2s) families derived from F(2) and backcrosses in a cross between two inbred lines. Genetic hypotheses that can be validly tested by the likelihood ratio method in the analysis of a breeding experi

16. Scaling phenomena in the Internet: Critically examining criticality
Recent Internet measurements have found pervasive evidence of some surprising scaling properties. The two we focus on in this paper are self-similar scaling in the burst patterns of Internet traffic and, in some contexts, scale-free structure in the network's interconnection topology. These findings have led to a number of proposed models or “explanations�

17. Improved predictive models for plasma glucose estimation from multi-linear regression analysis of exhaled volatile organic compounds
Exhaled volatile organic compounds (VOCs) represent ideal biomarkers of endogenous metabolism and could be used to noninvasively measure circulating variables, including plasma glucose. We previously demonstrated that hyperglycemia in different metabolic settings (glucose ingestion in pediatric Type 1 diabetes) is paralleled by changes in exhaled ethanol, ac

18. Contrast sensitivity, acuity, and the perception of 'real-world' targets.
A major assumption underlying the use of contrast sensitivity testing is that it predicts whether a patient has difficulty seeing objects encountered in everyday life. However, there has been no large-scale attempt to examine whether this putative relationship actually exists. We have examined this assumption using a clinic based sample of adults aged 20-77

19. Morphology of high-luminosity compact radio sources.
High-dynamic range imaging and monitoring with very-long-baseline interferometry reveal a rich morphology of luminous flat-spectrum radio sources. One-sided core-jet structures abound, and superluminal motion is frequently measured. In a few cases, both distinct moving features and diffuse underlying jet emission can be detected. Superluminal motion seen in

20. Transcription-Based Prediction of Response to IFNβ Using Supervised Computational Methods
Changes in cellular functions in response to drug therapy are mediated by specific transcriptional profiles resulting from the induction or repression in the activity of a number of genes, thereby modifying the preexisting gene activity pattern of the drug-targeted cell(s). Recombinant human interferon beta (rIFNβ) is routinely used to control exacerbations
