Bioelectrical impedance changes of the trunk are opposite the limbs following acute hydration change

open access: yesJournal of Electrical Bioimpedance, 2022
This study aimed to evaluate the changes in impedance and estimates of body composition variables obtained from segmental multi-frequency bioelectrical impedance analysis (SMFBIA) following acute hydration change.

Clean and Green Urban Water Bodies Benefit Nocturnal Flying Insects and Their Predators, Insectivorous Bats [PDF]

open access: yes, 2020
Nocturnal arthropods form the prey base for many predators and are an integral part of complex food webs. However, there is limited understanding of the mechanisms influencing invertebrates at urban water bodies and the potential flow-on effects to their

Seasonal changes in total body water; body composition and water turnover in reindeer

open access: yesRangifer, 1985
Total body water and water turnover were measured at different times throughout the year in 3 captive Norwegian reindeer, using a tritiated water dilution method (Holleman et al. 1982).

Bioelectrical impedance vector analysis (BIVA) in university athletes

open access: yesJournal of the International Society of Sports Nutrition, 2021
Background Bioelectrical impedance vector analysis (BIVA) is able to identify differences in hydration status and body composition components, such as body cell mass (BCM) by means of plotting individuals in ellipses, when comparing groups with different

Water Body Distributions Across Scales: A Remote Sensing Based Comparison of Three Arctic Tundra Wetlands [PDF]

open access: yes, 2013
Water bodies are ubiquitous features in Arctic wetlands. Ponds, i.e., waters with a surface area smaller than 104 m2, have been recognized as hotspots of biological activity and greenhouse gas emissions but are not well inventoried.

Triangle Water Index (TWI): An Advanced Approach for More Accurate Detection and Delineation of Water Surfaces in Sentinel-2 Data

open access: yesRemote Sensing, 2022
One of the most basic classification tasks in remote sensing is to distinguish between water bodies and other surface types. Although there are numerous techniques for extracting surface water from satellite imagery, there is still a need for research to

Small Water Body Detection and Water Quality Variations with Changing Human Activity Intensity in Wuhan

open access: yesRemote Sensing, 2022
Small water bodies ranging in size from 1 to 50,000 m2, are numerous, widely distributed, and have various functions in water storage, agriculture, and fisheries. Small water bodies used for agriculture and fisheries are economically significant in China,

bodies of water

open access: yesCommonwealth Essays and Studies, 2022
The author traces a local history of naming watery bodies and the erosion of the borders between formerly discrete places. She pushes back against the etymological suggestion of “bodies of water,” which suggests that different parts of the sea can be different and separate identities of one singular sea.
