Etude hydrogéologique des séries triasiques dans la région de Jeffara-Dahar (Sud Tunisien): Apport des diagraphies et de la sismique réflexion
The present study concentrates on the interpretation of well logs and seismic reflection data in the Jeffara- Dahar region (Southeast part of Tunisia) for a better characterization of the Triassic aquifer, a potential target of water supply. Lithological columns and their corresponding well logs reveal that Sidi Stout, Kirchaou and Touareg sandstones as well as Mekraneb and Rehach dolomites are the main reservoirs of the Triassic aquifer. Well log analysis highlights many permeable and fractured layers that could play an important role in the groundwater circulation.
The interpreted seismic sections and the resulting isochrone maps show a tectonic influence on the Triassic aquifer geometry in the Jeffara-Dahar region. The normal faulting of E-W and NW-SE accidents created an aquifer compartmentalized by raised and tilted blocks. Seismic cross-sections reveal that this structure controls the depth of permeable formations and the circulation of groundwater.
These results will be useful for rationalising the future hydrogeological research that will be undertaken in the Jeffara-Dahar area.[fr] La présente étude concerne l’interprétation des données de la sismique réflexion et celles des puits y compris les enregistrements diagraphiques en vue d’une meilleure caractérisation de l’aquifère triasique de la région de Jeffara-Dahar (Sud-Est de la Tunisie) qui constitue une cible potentielle pour l’alimentation en eau.
Les logs lithologiques associés aux enregistrements diagraphiques correspondants montrent que les principaux réservoirs sont les grés de Sidi Stout, Kirchaou et Touareg ainsi que les dolomies de Mekraneb et Rehach. L’interprétation diagraphique met en évidence des niveaux de faible perméabilité et d’autres perméables et bien fracturées qui pourraient jouer un rôle dans l’acheminement des eaux souterraines.
Les profils sismiques interprétés et la cartographie élaborée en conséquence mettent en évidence que l’aquifère triasique est compartimenté en blocs soulevés et affaissés. Cette structuration, contrôlée par la réactivation des accidents E-W et NW-SE en failles normales au cours du Trias, influence l’épaisseur des formations perméables ainsi que le sens d’écoulement de la nappe d’eau.
Les résultats obtenus seront utiles pour la rationalisation des futures recherches hydrogéologiques dans la région de Jeffara – Dahar

Desobstrução ineficaz das vias aéreas em crianças asmáticas: um estudo descritivo
STAAR: a randomised controlled trial of electronic adherence monitoring with reminder alarms and feedback to improve clinical outcomes for children with asthma
Background Suboptimal adherence to inhaled steroids
is common in children with asthma and is associated
with poor disease control, reduced quality of life and
even death. Previous studies using feedback of
electronically monitored adherence data have
demonstrated improved adherence, but have not
demonstrated a significant impact on clinical outcomes.
The aim of this study was to determine whether
introduction of this approach into routine practice would
result in improved clinical outcomes.
Methods Children with asthma aged 6–16 years were
randomised to the active intervention consisting of
electronic adherence monitoring with daily reminder
alarms together with feedback in the clinic regarding
their inhaled corticosteroid (ICS) use or to the usual care
arm with adherence monitoring alone. All children had
poorly controlled asthma at baseline, taking ICS and
long-acting β-agonists. Subjects were seen in routine
clinics every 3 months for 1 year. The primary outcome
was the Asthma Control Questionnaire (ACQ) score.
Secondary outcomes included adherence and markers of
asthma morbidity.
Results 77 of 90 children completed the study
(39 interventions, 38 controls). Adherence in the
intervention group was 70% vs 49% in the control
group (p≤0.001). There was no significant difference in
the change in ACQ, but children in the intervention
group required significantly fewer courses of oral
steroids (p=0.008) and fewer hospital admissions
(p≤0.001).
Conclusions The results indicate that electronic
adherence monitoring with feedback is likely to be of
significant benefit in the routine management of poorly
controlled asthmatic subjects
