The role of nutritional impairment in carbon‐water balance of silver fir drought‐induced dieback
Global Change Biology, Volume 28, Issue 14, Page 4439-4458, July 2022., 2022 Declining silver fir trees show lower foliar concentrations of essential nutrients such as P, K, Cu and Ni than non‐declining trees. This nutritional impairment exacerbates and amplifies the negative effects of drought on tree functioning and growth, considering the relationship of tree nutritional status with water‐use efficiency and growth resilience

International Journal of Food Science &Technology, Volume 56, Issue 10, Page 5409-5416, October 2021., 2021 To dry at 50 °C while freeze‐drying shortens the process time, promotes the vitamin C content, improves the mechanical properties of the cake and does not affect the flowability and the rehydration behaviour of the powdered product. Summary Freeze‐drying is a good alternative means of obtaining fruit products, with a significant amount of thermolabile ...

A Review of Codes and Standards for Bamboo Structural Design
Advances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021 Bamboo is a strong, fast‐growing, and sustainable material. In modern times, it can be an aesthetically pleasing and low‐cost alternative to more conventional materials. Despite the literature’s consideration of bamboo’s promising potential as a resilient, sustainable building material for structural element design, its application is limited.
