Feasibility study of a discrete bearing/roller drive rotary joint for the space station [PDF]

open access: yes
The most critical mechanism on board the proposed space station is the continously rotating joint which must accurately align the solar power units with the sun during earth orbit. The feasibility of a multiple, discrete bearing supported joint driven by

Fascinating single‐cell red algae: models for evolution and adaptation

open access: yesNew Phytologist, EarlyView.
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

Bibliometric‐Based Analysis of Global Trends and Collaborative Networks in Plant Genetic Engineering (1994–2024)

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Agricultural sustainability faces serious challenges from population growth, climate change and ecological degradation. Genetic modification (GM) technology can be regarded as a precise extension of the Green Revolution, aiming to balance yield enhancement with ecological integrity through biotechnology. To systematically examine global trend,

Redistribution of soil water by mature trees towards dry surface soils and uptake by seedlings in a temperate forest

open access: yesPlant Biology, EarlyView.
Mature beech trees redistributed soil water, equal to ca. 10% of stand transpiration, from deeper moist soils to dry surface soils, where it was taken up by seedlings of different tree species. Abstract Hydraulic redistribution is considered a crucial dryland mechanism that may be important in temperate environments facing increased soil drying–wetting
