Algorithm for sizing parabolic-trough solar collectors

Thermal Science and Engineering Progress, 2021
Abstract This work aims at developing a working algorithm to evaluate the necessary parabolic-trough solar collectors (PTCs) sizing for any application, basically, as a function of the thermal load and the demanded operating temperature. Energy balance and heat transfer accurate estimations were applied to the PTC parts resulting in a set of non ...

Feasibility of dried blood spot collection for caffeine pharmacokinetic studies in microgravity: Insights from parabolic flight campaigns

British Journal of Clinical Pharmacology, Volume 92, Issue 1, Page 35-47, January 2026.
Abstract Aims Therapeutic drug monitoring for astronauts faces limitations in conventional blood sampling and sample management onboard the international space station. Here, we explore the feasibility of dried blood spot (DBS) collection during parabolic flights (PF) to overcome these constraints.

Field Experiments of Rainfall‐Induced Weathered Granite Residual Soil Shallow Landslides

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Affected by the extreme climate in recent years, the heavy rainfall has induced a large number of shallow landslides along roads in the granite residual land area in southeast China. Currently, the hydraulic response, evolution mechanism, and failure process of unsaturated granite residual soil landslides at the field scale are not well understood.
