Rapid Fluctuations in Earth-Currents at College [PDF]

open access: yes, 1959
An unusual type of earth-current variation is regularly observed in the College records. The phenomena consist of more or less regular fluctuations with range from a few mv/km to more than 1000 mv/km, and periods ranging upwards from 6 seconds.

Diurnal variation in neutrophil function

open access: yesEnvironmental Health and Preventive Medicine, 1996
Neutrophil functions, including chemotaxis, reactive oxygen species (ROS)-producing capacity of neutrophils, and serum opsonic activity were investigated in 9 young healthy male volunteers. Venous blood of these volunteers was obtained under standardized conditions at 4-h intervals over a 24-h span.

Plant Robotics for Sustainable and Environmentally Friendly Robots: Insights from Actuation Characteristics

open access: yesAdvanced Science, EarlyView.
Plants are promising materials for building sustainable and eco‐friendly robots due to their inherent multifunctionality, with actuation playing a crucial role. This article focuses on the physical movements of plants and, from the perspective of actuation characteristics, explores representative plant species and their behaviors, the current state of ...

Photometric Studies of Auroral Luminosity and its Connection with Some Atmosphere Ionization Phenomena [PDF]

open access: yes, 1958
The auroral radiation, 3914 AO, received from the entire sky on a horizontal diffusing plate was monitored continuously during the nights of 1955-56 and 1956-57. The 1955-56 data and part of the 1956-57 data were used to obtain a diurnal curve for the

Multifunctional Tailoring of Fertilizer Composites Directly Derived From Phosphate Rock

open access: yesAdvanced Science, EarlyView.
A novel phosphorus‑sulfur mixed acid with urea (PSU) activation system converts low‑grade phosphate rock (LPR) into multifunctional fertilizer composites (MFCs). MFCs feature porous structures, high nutrient‑activation efficiency, superior slow‑release, and enhanced crop growth, offering a sustainable solution for integrated nutrient management and ...
