Abstract:
... In cities in temperate climate zones, the elderly, disabled and socially deprived are most vulnerable to extreme heat, as witnessed by increased mortality rates during heat waves in Europe and North America. Many cities, however, lag behind in the protection of vulnerable citizens against heat stress, an issue gaining importance in the face of climate change, ongoing urbanization and an ageing pop ...
... An imino N-heterocyclic carbene underwent three sequential benzyl migrations upon reaction with tetrabenzylhafnium, resulting in complete removal of the carbene carbon from the ligand. The resulting eneamido-amidinato hafnium complex showed alkene polymerization activity comparable to that of a precatalyst containing the intact iminocarbene ligand. ...

Abstract:
... Studies of alternative food networks have proliferated in Europe and North America while relatively little attention has been paid to similar networks in the global South. An organic farmers market in Lima, Peru, serves as a case study to examine developments in the domestic market for organic produce in Peru. Drawing from interview data and participant observations with pioneering organic farmers ...
... In Italy the âminimal pruning systemâ (a definition derived from the grapevine pruning technique) is generally utilized in peach orchards. One of its main rules is to initially obtain a âfree spindle bushâ shape, avoiding cutting back the scion at planting time but using lateral shoots to form future fruiting branches. This experiment involved a comparison of three high density peach plots ...
... During their life cycle, citrus plants can experience different processes involving separation of cells by dissolution of cell adhesion materials and breakdown of cell walls at specific sites on the plant body. Abscission enables both vegetative and reproductive organs to be shed in response to developmental, hormonal and environmental cues. From an evolutionary point of view, abscission is a high ...

Abstract:
... Agrifood movement literature largely represents food system labor through images, descriptions, and depictions of farm workers and other agriculture-related labor, such as slaughtering and meatpacking. Although engaging in a holistic dialogue that considers the continuum of labor abuse across the food system may be a difficult task, privileging production-oriented food system labor reinforces what ...
