Setting up a decision rule from estimated uncertainty : emission limit value for PCDD and PCDF incineration plants in Wallonia, Belgium.

Complex analytical procedures are often required to prove the non-compliance with a specific legislation. In the case of a small overlap of the limit, integration of the method uncertainty in the decision-making process is essential. The decision rule proposed in Wallonia, Belgium, for the non-compliance of waste incineration plants with the EU limit value for PCDD and PCDF emissions is presented. The method uncertainty was estimated annually over 6 years from duplicate measurements using two top-down approaches. Depending on the congener, the standard uncertainty varies from 30 to 85%, with a good correlation between calculations. The analytical contribution was estimated using a bottom-up evaluation. The impact of the sampling step was deduced from the whole estimation and represents more than 80% of the total uncertainty budget. No optimisation is foreseen at this time because of practical field constraints. Based on the average fraction of each congener, the uncertainty associated with the measurement result has been established and shows a high stability over the years. Using this value, a guard band has been calculated and will be proposed to the regulatory body. [less ▲]

Analysis of Semi-Continuous Composite Beams with Partial Shear Connection Using 2-D Finite Element Approach

In this study, a two-dimensional finite element model using ANSYS software was proposed to study the behaviour of semi-continuous composite beams allowing for the concept of partial shear connection in both sagging and hogging moment regions. Some comparisons with experimental data available in the literature were reported to validate the efficiency of the proposed model. Using the verified model, a parametric study was carried out to investigate the effects of partial shear connection, along with the effects of reinforcing ratio and the presence of column web stiffeners, on the behaviour of semi-continuous composite beams. Based on the results obtained from the finite element analysis, the concept of partial shear connection in the hogging moment regions can be accepted provided that the shear connectors are sufficiently ductile, in spite of the requirement of full shear connection specified in Eurocode 4 for continuous and semi-continuous composite beams.

The authors describe the four patients in the first known Belgian family with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). A novel homozygous missense mutation, NM_014363.3: c.3491T>A in exon 9, of the SACS gene was identified in the present family, which results in an original amino acid of methionine to lysine substitution at amino acid residue 1164 (p.M1164K). Although the cardinal clinical features, i.e., spastic ataxia with peripheral neuropathy, in our patients were similar to those in Quebec patients, our patients exhibited some atypical clinical features, e.g., teenage-onset and absence of retinal hypermyelination. The present family is from Wallonia, and there could be shared ethnicity with the families of Charlevoix-Saguenay. [less ▲]
