This article presents a fiber Bragg grating–based monitoring and warning system for expressway slopes. A detailed architecture of the sensing system based on fiber Bragg grating sensors for safety analysis and pre-warning of slopes is described and interpreted. The whole warning and monitoring system was mainly realized based on two monitored parameters from fiber Bragg grating strain sensors: (1) the measured bend strain of inclinometers for the calculation of horizontal displacement and (2) axial strain distributions of soil nails. The maximum magnitudes of cumulative strain and displacement in the present monitored expressway slope were 198 με and 5.06 mm, respectively. Critical threshold values of different warning levels for expressway slopes have been proposed using statistical analysis method based on comparative analysis of history monitored data from slopes in the same region. A total of four warning levels characterized by different ranges of displacement rates and the related engineering measures to treat expressway slopes were proposed and discussed. This fiber Bragg grating–based monitoring system of soil nails and inclinometers forms a real-time sensing network, assisting engineers to adopt quick and essential measures to deal with potential landslide risk.

The Stability

The UNESCO World Heritage Site of Petra is characterized by a spectacular geo-archaeological landscape that lead to its inscription as World Heritage Site in 1985. Petra is also a fragile site facing a wide diversity of risks, ranging from those posed by environmental factors as well as those attributed to tourism. In recent years, hazardous natural phenomena were registered as increasingly impacting the site, and most specifically the 'Siq', a 1.2 km naturally formed gorge serving as the only tourist entrance to the archaeological park, posing a major threat to cultural heritage and visitors. These recent events have prompted UNESCO Amman Office, in cooperation with the national authorities, to develop a strategy towards prevention and mitigation of instability phenomena at the 'Siq' and, thus, further contribute to the management and conservation of the site through the implementation of the multi-year Italian funded "Siq Stability" project Actions have been primarily focusing on the analysis of the stability conditions of the 'Siq' slopes, the installation of an integrated monitoring system and the definition and implementation of mitigation measures against rock instability. This paper reports a detailed description of the integrated monitoring system installed paying particular attention on the wireless monitoring devices and the EASA applications, which proved to be some of the most successful systems implemented in the framework of the project. Some preliminary results regarding the data retrieved, policies applied and actions taken to ensure long-term sustainability and capacity development of the national authorities are also reported.

<span class="fett">Hintergrund und Zielsetzung:</span> PHAR-MON ist ein Monitoring-System, das die auf dem deutschen Markt befindlichen Arzneimittel in ihrer Bedeutung für die Entwicklung von Missbrauch und Abhängigkeit in Suchtberatungsstellen überwacht. </p><p> <span class="fett">Methodik:</span> Klienten ambulanter Beratungsstellen werden im Rahmen der Standarddokumentation zu ihrem Arzneimittelkonsum befragt und Fälle eines abhängigen Konsums, eines schädlichen Gebrauchs oder eines Missbrauchs in PHAR-MON dokumentiert. </p><p> <span class="fett">Ergebnisse:</span> Im Jahr 2006 wurden insgesamt 448 Meldungen von 276 überwiegend alkohol- und drogenabhängigen Klienten in das Monitoring einbezogen. Tranquilizer vom Benzodiazepin-Typ wurden in allen Klientengruppen mit Anteilen zwischen 29,1 % und 35,3 % am häufigsten dokumentiert. An benzodiazepinabhängige Klienten werden zunehmend auch Nicht-Benzodiazepin-Hypnotika verordnet. Bei opioidabhängigen Klienten war im Zeitraum der letzten fünf Jahre ein Anstieg im missbräuchlichen Substitutionsmittelkonsum von 14,9 % auf 33,8 % zu verzeichnen. </p><p> <span class="fett">Schlussfolgerungen:</span> Das Risiko gefährlicher Wechselwirkungen zwischen Arzneimitteln mit Alkohol und Drogen sollte stärker als bisher in die ärztliche Verordnungsentscheidung einbezogen werden.
