New approach for time-resolved and dynamic investigations on nanoparticles agglomeration

Anaraki, Neda Iranpour ; Sadeghpour, Amin ; Iranshahi, Kamran ; Toncelli, Claudio ; Cendrowska, Urszula ; Stellacci, Francesco ; Dommann, Alex ; Wick, Peter ; Neels, Antonia

In: Nano Research, 2020, vol. 13, no. 10, p. 2847–2856

Nanoparticle (NP) colloidal stability plays a crucial role in biomedical application not only for human and environmental safety but also for NP efficiency and functionality. NP agglomeration is considered as a possible process in monodispersed NP colloidal solutions, which drastically affects colloidal stability. This process is triggered by changes in the physicochemical properties of the...

Predicting impact of a biocontrol agent: integrating distribution modeling with climate-dependent vital rates

Augustinus, Benno ; Sun, Yan ; Beuchat, Carine ; Schaffner, Urs ; Müller‐Schärer, Heinz

In: Ecological Applications, 2020, vol. 30, no. 1, p. e02003

Species distribution models can predict the suitable climatic range of a potential biological control agent (BCA), but they provide little information on the BCA's potential impact. To predict high population buildup, a prerequisite of biocontrol impact, studies are needed that assess the effect of environmental factors on vital rates of a BCA across the environmental gradient of the BCA's...

The importance of geographical proximity : Evidence on the concentration of firms, culture and political ideologies

Mantegazzi, Daniele ; Maggi, Rico (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO008.

This dissertation proposes three empirical essays focusing on the importance of geographical concentrations along various dimensions in regional economics, dealing with topics regarding agglomeration spillovers, firm performance, culture and soft institutions as well as the geographical concentration of political ideologies. The first chapter aims at empirically verifying whether agglomeration...

Biological invasion of oxeye daisy (Leucanthemum vulgare) in North America: Pre-adaptation, post-introduction evolution, or both?

Stutz, Sonja ; Mráz, Patrik ; Hinz, Hariet L. ; Müller-Schärer, Heinz ; Schaffner, Urs

In: PLOS ONE, 2018, vol. 13, no. 1, p. e0190705

Species may become invasive after introduction to a new range because phenotypic traits pre-adapt them to spread and become dominant. In addition, adaptation to novel selection pressures in the introduced range may further increase their potential to become invasive. The diploid Leucanthemum vulgare and the tetraploid L. ircutianum are native to Eurasia and have been introduced to North...

The millennial generation reshaping the workplace : what changes are needed for organizations to attract and retain employees ?

Mauricio, Inès Pereira ; Miller, Caroline (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2017 ; TDIBM 16.

This report aims to measure how different is the Millennial generation from the Western world from their predecessors and identify ways in which firms should adapt in order to attract and retain these new talents. These recommendations will not only take into account generational aspects of this challenge, but also the overall environment and the different forces shaping the future of work. Two...
