Investigating musculoskeletal risks in manual mushroom harvesting: An ergonomic field study in canadian farms

open access: yesSocial Sciences and Humanities Open
Canada's annual production of 132,000 metric tonnes of mushrooms relies on manual harvesting, posing risks of work-related musculoskeletal disorders (WMSDs). This study employs ergonomic evaluation techniques, including Rapid Upper Limb Assessment (RULA)

Timing of calcification and environmental variability determine pH proxy fidelity in coastal calcifying macroalgae

open access: yesLimnology and Oceanography, EarlyView.
Abstract Long‐lived calcifying marine biota are increasingly used as paleo‐archives for reconstructing ocean pH. They enable exploration of the rate and magnitude of ocean acidification in shallow‐water ecosystems serving as proxies for environmental pH reconstruction.

Inhibition of cosmopolitan toxic diatom, Pseudo‐nitzschia, by seaweeds

open access: yesLimnology and Oceanography, EarlyView.
Abstract Pseudo‐nitzschia is a genus of harmful algal bloom (HAB)‐forming diatoms that can produce domoic acid (DA), a compound known to cause death and disease in marine wildlife as well as amnesic shellfish poisoning in humans. Here, we show the effects of multiple cultivable seaweeds—Saccharina latissima (sugar kelp), Ulva spp., and Gracilaria spp ...

Enhanced benthic biodiversity and primary productivity with reduced turbidity in a coastal receiving environment

open access: yesLimnology and Oceanography, EarlyView.
Abstract Sediment loading from land and turbidity in coastal waters has increased because of human activities in coastal catchments and through climate‐related increases in storm intensity and frequency. Here, we investigated changes in coastal seafloor biodiversity and ecosystem function across a suspended sediment concentration gradient in a New ...

From temperate to polar waters: Transition to non‐cyanobacterial diazotrophy upon entering the Atlantic gateway of the Arctic Ocean

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nitrogen fixation, the microbial reduction of dinitrogen to ammonia, is increasingly recognized to occur in the Arctic Ocean. However, knowledge about the composition, biogeography, abundance, and ecology of nitrogen‐fixing organisms (diazotrophs) is poor.

A Remarkable Sunset

open access: yesNature, 1885
WHILE out for a walk this afternoon I was struck by a peculiarity in the sunset which I do not remember to have seen noticed before.

Optimized Hybrid Resource Allocation in Wireless Cellular Networks with and without Channel Reassignment

open access: yesJournal of Computer Systems, Networks, and Communications, 2010
In cellular networks, it is important to determine an optimal channel assignment scheme so that the available channels, which are considered as “limited” resources in cellular networks, are used as efficiently as possible.
