A CE method for metacycline (MTC) determination was investigated in an inter-laboratory experiment. Many problems were encountered in this study, most of which were related to the transfer of the method to different CE equipment. The reported problems could be classified into different categories: problems related to the precision, to the parameters in the protocol, and to the MTC peak shape. As the peak shape problem was partially responsible for the poor precision, a new CE method was developed in order to obtain a good MTC peak shape on all equipment. The precision of this new method for MTC determination was examined in an intermediate precision study, where the influence of the factors "time" and "equipment" was investigated. Although the new method could be transferred to different instruments, the precision remained poor mainly due to the contributions of the between-replicate and the between-injection variances.

AIMS: Bovine meat is the principal source of human contamination of attaching and effacing Escherichia coli, including enterohaemorrhagic E. coli O157. The aim was to study the prevalence of these strains on bovine carcasses in Algeria. METHODS AND RESULTS: Two-hundred and thirty carcasses were swabbed and analysed by classical microbiological methods for total E. coli counts and for the presence of pathogenic E. coli. The E. coli counts were high, with a 75th percentile of 444.75 CFUs cm(-2). For pathogenic E. coli, more than 7% of the tested carcasses were positive for E. coli O157. Eighteen E. coli O157 strains were isolated and typed by multiplex PCR. The main isolated pathotype (78%) was eae+ stx2+ ehxA+. In addition to E. coli O157, other attaching and effacing E. coli (AEEC) were also detected from carcasses by colony hybridization after pre-enrichment and plating on sorbitol MacConkey agar using eae, stx1 and stx2 probes. Thirty carcasses (13%) on the 230 analysed harboured at least one colony positive for one of the tested probes. These positive carcasses were different from those positive for E. coli O157. Sixty-six colonies (2.9%) positive by colony hybridization were isolated. The majority (60.6%) of the positive strains harboured an enteropathogenic E. coli-like pathotype (eae+ stx-). Only three enterohaemorrhagic E. coli (EHEC)-like (eae+ stx1+) colonies were isolated from the same carcass. These strains did not belong to classical EHEC serotypes. CONCLUSIONS: In this study, the global hygiene of the slaughterhouse was low, as indicated by the high level of E. coli count. The prevalence of both E. coli O157 and other AEEC was also high, representing a real hazard for consumers. SIGNIFICANCE AND IMPACT OF THE STUDY: This is the first study of this type in Algeria, which indicates that the general hygiene of the slaughterhouse must be improved. [less ▲]

We aimed to determine IgE-dependant skin sensitization rates to moulds, dermatophytes and yeasts in patients with typical allergic diseases in comparison to those with inflammatory dermatitis seen over the course of one year. Skin prick tests were done in 267 patients (172 women and 95 men; median age 38 years, range 25–50 years). We allocated them into 8 groups: 64 with head and neck atopic dermatitis; 11 with seborrheic dermatitis; 52 with eczema and not atopic dermatitis other than on the head and neck; 64 with rhinitis, conjunctivitis and asthma; 28 with urticaria; 10 with food allergy; and 12 healthy controls. Skin tests were done with the following aqueous standardized commercial extracts: Alternaria, Penicillium, Aspergillus, Cladosporium, Mucor, Trichophyton, Epidermophyton, Candida albicans, Malassezia and Saccharomyces cerevisiæ. Globally, positive skin test reactions occurred most frequently with the yeast extracts, less to the dermatophytes and even less to the moulds. The results were homogenous among members of each group. The relevance of our tests was reinforced by the fact that the moulds that gave positive skin tests most frequently were those most often isolated in the Belgian environment. In patients with atopic dermatitis of the head and neck, positive tests were most frequent with four moulds and three yeasts; compared to this group, positive tests were less frequent in patients with atopic dermatitis localized to other sites. In inflammatory dermatitis of the head and neck, the study of immediate hypersensitivity to yeasts seems to be important. [less ▲]

This paper surveys the theoretical economic literature on foreign aid -- in particular, the aid donor–recipient relationship. Economic theory, especially new institutional economics, can be very helpful in understanding foreign aid relationships -- especially the incentive problems involved -- and in designing institutions to improve aid effectiveness. In particular, it helps in understanding the chain of principal–agent relations inherent in the aid delivery system and the resulting potential for agency problems. The survey shows that economic theory can improve the design of cooperation modalities by aligning the incentives of donors and recipients for poverty reduction, but that, in order to address the problems, policy analysis must take into account the constraints faced by stakeholders in the aid relationship. The aid 'contract' should thus seek to improve the agents' incentives to use aid effectively, given the circumstances of the developing country [less ▲]

Recently, a first step towards a highly distributed IP-level topology dis- covery tool has been made with the introduction of the Doubletree al- gorithm. Doubletree is an efficient cooperative algorithm that allows the discovery of a large portion of nodes and links in the network while strongly reducing probing redundancy on nodes and destinations as well as the amount of probes sent. In this paper, we propose to reduce more strongly the load on destinations and, more essentially, the communica- tion cost required for the cooperation by introducing a probing stopping rule based on CIDR address prefixes.

The implementation of the Water Framework Directive (EU 2000) requires a groundwater quality monitoring. It is used for characterisation of the 'good' chemical status of each groundwater body and for the restoration or protection purposes of those bodies already at 'good' status. Interpretative aspects are lying in the design of monitoring network and in the way of building global indicators. Attention is given here to the global chemical status of the groundwater bodies and to the role of diffuse pollution, much of which is brought via groundwater to surface water. Monitoring 'local' pollution associated with individual sites is not addressed. Groundwater bodies with different contrasted hydrogeology conditions, land use and topography have been considered to establish an approach for choosing an optimised monitoring network. Then, a quality assessment system has been developed and applied for qualifying the general status of each groundwater body. The use of non-dimensional indexes allows us to process with all kinds of chemical parameters in a normalised way and, by means of adequate aggregation rules, to qualify the general quality status of a groundwater body. The obtained diagnostic, even if not fully validated, is closely linked to the pragmatic objectives contained in the EU Water Directive. [less ▲]
