Seismic monitoring in the Gugla rock glacier (Switzerland): ambient noise correlation, microseismicity and modelling

Guillemot, Antoine ; Helmstetter, Agnès ; Larose, Éric ; Baillet, Laurent ; Garambois, Stéphane ; Mayoraz, Raphaël ; Delaloye, Reynald

In: Geophysical Journal International, 2020, vol. 221, no. 3, p. 1719–1735

A network of seismometers has been installed on the Gugla rock glacier since October 2015 to estimate seismic velocity changes and detect microseismicity. These two processes are related to mechanical and structural variations occurring within the rock glacier. Seismic monitoring thus allows a better understanding of the dynamics of rock glaciers throughout the year. We observed seasonal...

Rapid polymyxin/pseudomonas NP test for rapid detection of polymyxin susceptibility/resistance in Pseudomonas aeruginosa

Sadek, Mustafa ; Tinguely, Camille ; Poirel, Laurent ; Nordmann, Patrice

In: European Journal of Clinical Microbiology & Infectious Diseases, 2020, p. -

Polymyxins are becoming an added value for treating infections due to multidrug-resistant Pseudomonas aeruginosa. Therefore, the Rapid Polymyxin/Pseudomonas NP test was developed for the identification of polymyxin resistance in P. aeruginosa isolates. This test detects the bacterial growth in a medium containing a defined concentration of colistin. Formation of basic metabolites is visually...

Using stagger charts to improve the accuracy of demand forecasts

Ramosaj, Agneta ; Widmer, Marino

(Internal working papers DIUF ; 20-01)

Nowadays, no business organization can avoid the need for accurate demand forecasting. It helps make the right decisions at every level, strategic or operational, and it is the center of financial simulation or procurement decisions in terms of production. A way to depict company forecasts could be provided by a stagger chart, a visual tool that is easy to implement and is understandable at...

Internal lamellar and inverse hexagonal liquid crystalline phases during the digestion of krill and astaxanthin oil-in-water emulsions

Yaghmur, Anan ; Lotfi, Saleh ; Ariabod, Sarah Atoussa ; Bor, Gizem ; Gontsarik, Mark ; Salentinig, Stefan

In: Frontiers in Bioengineering and Biotechnology, 2019, vol. 7, p. -

Krill oil represents an important alternative natural source of omega-3 (ω-3) polyunsaturated fatty acids (PUFAs). Considering the beneficial health effects of these essential fatty acids, particularly in various disorders including cancer, cardiovascular, and inflammation diseases, it is of paramount importance to gain insight into the digestibility of krill oil. In this work, we study the...
