Outdoor adventure education (OAE) has long held on to the assumption that learning is transferred to participants’ lives (e.g., Gass, 1985). Recent scholars have contested this assumption, noting that learning transfer may not be a complete lens through which learning is viewed. Transformative learning theory (e.g., Mezirow, 1991) has been...

Fluctuations and spatial heterogeneity of habitat and resources is thought to underlie niche variation in animal populations, with intraspecific differences serving to produce or maintain population-, community-, or ecosystem-level patterns. Individual diet variation, defined as individual variation in food resource use within a population that is consistent over time, is...
Photonic sintering of nanoparticles is a relatively new process for sintering of nanoparticles, deposited on a substrate, into functional solid structures. The working principle of this process is the incidence of large-area broad-spectrum light onto deposited nanoparticles, which results in heat generation in the nanoparticles and their subsequent densification. Key...

M. avium is an opportunistic pathogen that primarily infects macrophages. In order to survive within the macrophage, M. avium secretes proteins into the host cell cytoplasm to inhibit specific functions such as phagosome acidification, altering pathways as well as initiating apoptosis. However, little is known about how those secreted proteins...
