Plant characteristics for distinction of red chicory (Cichorium intybus L. var. silvestre Bisch.) cultivars grown in central Slovenia

Acta Agriculturae Slovenica, 2004
Eight red chicory (Cichorium intybus L. var. silvestre Bisch.) cultivars were screened for plant characteristics, yield, resistance to Erysiphe cichoracearum and their persistence of bolting over a two-year period (2002 and 2003 growing seasons) in ...

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

Advanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

Selection on BrFLC1 Is Related to Intraspecific Diversity of Brassica rapa Vegetables

Horticulturae, 2021
Flowering time is important for Brassica rapa vegetables because premature bolting before harvest can lower yield and quality. FLOWERING LOCUS C (FLC) acts as a key repressor of flowering. In this study, we identified a nonsynonymous mutation at the 58th

Seismic performance of cold-formed steel bolted moment connections with bolting friction-slip mechanism [PDF]

, 2019
Typical cold-formed steel (CFS) moment-resisting connections generally have relatively low ductility and energy dissipation capacity as a result of low local/distortional buckling resistance of thin-walled CFS elements, and therefore, may not be suitable

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

Advanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

No evidence for early fitness penalty in glyphosate‐resistant biotypes of Conyza canadensis: Common garden experiments in the absence of glyphosate

Ecology and Evolution, 2019
Strong selection from herbicides has led to the rapid evolution of herbicide‐resistant weeds, greatly complicating weed management efforts worldwide. In particular, overreliance on glyphosate, the active ingredient in RoundUp®, has spurred the evolution ...
