Stable hydrogen-isotope ratios (deltaD) of keratin provide a novel means for tracking geographical movements of birds and other species. Here we describe a rapid, low cost, analytical approach to facilitate online continuous-flow isotope-ratio mass spectrometry (CF-IRMS) deltaD analyses of keratins (120-160 samples per day) through the use of calibrated keratin working standards and "comparativ...

Cell migration through 3D extracellular matrices is critical to the normal development of tissues and organs and in disease processes, yet adequate analytical tools to characterize 3D migration are lacking. Here, we quantified the migration patterns of individual fibrosarcoma cells on 2D substrates and in 3D collagen matrices and found that 3D migration does not follow a random walk. Both 2D an...

in this paper we tried to analyze the relationship between migration, informal settlement, and unemployment in ahvaz as the regional metropolis of khuzestan state. unemployment and migration interaction effect with each other. because on the one hand unequal distribution facilities and services leads to unemployment and job for people, the other hand, mass unemployment in section of the workfor...

This article shows how certain practical/analytical skills are developed for “doing” leadership (Alvesson & Spicer, 2011) through what I call mindful classroom simulations in two upper-level social science courses. By drawing from various leadership definitions and Ellen J. Langer’s Mindfulness (1989) construct and through the use of an online open-ended questionnaire, participant-observation, ...

The difficulties in communicating climate change science to the general public are often highlighted as one of the hurdles for support of enhanced climate action. The advances of interactive visualization using information and communication technology (ICT) are claimed to be a game-changer in our ability to communicate complex issues. However, new analytical frameworks are warranted to analyse ...
