Dynamic ammonium retention for nutrient separation from manure digestate.

Extensive nitrogen emissions with negative impact on nature and the environment urge effective valorization of manure and fractionation of nutrients to enable precision fertilization. Typically, manure is fed to a digester to produce biogas. The remaining digestate is then mechanically separated into a solid phosphorous-rich fraction and a liquid fraction containing both NH and K.

Field sampling of fig pollinator wasps across host species and host developmental phase: Implications for host recognition and specificity.

Previous genetic studies of pollinator wasps associated with a community of strangler figs ( subgenus , section ) in Central Panama suggest that the wasp species exhibit a range in host specificity across their host figs. To better understand factors that might contribute to this observed range of specificity, we used sticky traps to capture fig-pollinating wasp individuals at 13 species, sampling at different phases of the reproductive cycle of the host figs (e.g.

Neighbourhood walkability in relation to cognitive functioning in patients with disorders along the heart-brain axis.

This study examined associations of neighbourhood walkability with cognitive functioning (i.e., global cognition, memory, language, attention-psychomotor speed, and executive functioning) in participants without or with either heart failure, carotid occlusive disease, or vascular cognitive impairment.
