[What obstacles to nursing home for Dependent older adults’ entry? Analysis of 186 situations resulting from an Inter-Establishment Resident Orientation Commission].

The decision to admit an older adult with loss of autonomy to an institution is complex. There are many obstacles to the decision to be referred to an institution and it partly explain long hospital stays and inadequate health care spending. Several of these obstacles have been identified in the literature (medical complexity, psycho-behavioural disorders, social vulnerability, etc.

Implementation of the anaerobic digestion model (ADM1) in the PHREEQC chemistry engine.

Anaerobic digestion is state-of-the-art technology to treat sludge and effluents from various industries. Modelling and optimisation of digestion operations can be advantageously performed using the anaerobic digestion model (ADM1) from the International Water Association. The ADM1, however, lacks a proper physico-chemical framework, which makes it difficult to consider wastewater of complex ionic composition and supersaturation phenomena.

Plant-derived compounds as natural antimicrobials to control paper mill biofilms.

Biofilms can cause severe problems in industrial paper mills, particularly of economic and technological types (clogging of filters, sheet breaks or holes in the paper, machine breakdowns, etc.). We present here some promising results on the use of essential oil compounds to control these biofilms.

Heterogeneity and spatial distribution of bacterial background contamination in pulp and process water of a paper mill.

Identifying the source and the distribution of bacterial contaminant communities in water circuits of industrial applications is critical even when the process may not show signs of acute biofouling. The endemic contamination of facilities can cause adverse effects on process runability but may be masked by the observed daily variability. The distribution of background communities of bacterial contaminants may therefore be critical in the development of new site-specific antifouling strategies.

Seroepidemiology of Helicobacter pylori infection in Guadeloupe.

854 sera collected from blood donors in Guadeloupe were screened for Helicobacter pylori immunoglobulin G antibodies by a commercial enzyme-linked immunosorbent assay kit. The overall prevalence was 55.2%; it increased significantly with age from 36.
