Comparative Performance Analysis of Various Flat Plate Solar Collectors Incorporating Spiral and Square Arrangement of Circular Type Riser Tube

Energy Science &Engineering, EarlyView.
Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.

Species Association of the Dominant Tree Species in an Old-Growth Forest and Implications for Enrichment Planting for the Restoration of Natural Degraded Forest in Subtropical China

, 2019
Subtropical natural forests are unique due to their ecological and economic functions. However, most of these forests are highly degraded, which impairs the ability to provide ecological and economic benefits. Enrichment planting is an important approach

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

How much grassland do we need?

Grassland Research, EarlyView.
A scaling analysis of global planted grassland area vs. country size. Abstract The United Nations has designated 2026 as the International Year of Rangelands and Pastoralists, drawing attention to the importance of grasslands and the communities that rely on them. Rangelands cover 54% of Earth's land surface, including grasslands, savannas, shrublands,
