Water ascends in woody plants : so what? [PDF]

open access: yes, 2013
Woody plants are often considered as static individuals, taking up water via the root system and losing it again via leaf transpiration. Quite boring one might conclude when considering that more than 95% of the water taken up by the roots is transpired ...

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Genetic dissection of two fibre yield-related stem traits in ramie (Boehmeria nivea L. Gaud)

open access: yesBiotechnology & Biotechnological Equipment, 2019
Ramie fibres are harvested from the stem bark of the plant, and thus two stem traits—the stem length (SL) and the stem diameter (SD)—are important components of fibre yield in this crop.

Seal-off assembly permits rapid evacuation of air from containers [PDF]

open access: yes, 1966
Seal-off assembly which permits rapid container evacuation using large diameter tubing has a vacuum valve that permits sealing plate transfer from the vacuum valve stem to the container after evacuation. The sealing plate can be reused repeatedly.

The Growth and Survival of Early Instars of \u3ci\u3eBellura Obliqua\u3c/i\u3e (Lepidoptera: Noctuidae) on \u3ci\u3eTypha Latifolia\u3c/i\u3e and \u3ci\u3eTypha Angustifolia\u3c/i\u3e [PDF]

open access: yes, 2017
Larvae of the noctuid moth Bellura obliqua are frequently encountered on Typha latifolia, but less commonly on Typha angustifolia. Experiments were conducted to compare the growth and survivorship of early B. obliqua instars on the two species of cattail.

Influence of Bark Beetle Infestation on Stem Diameter Dynamics

open access: yesTrees, Forests and People
Bark beetle epidemics have increased globally due to drought and a warming climate, impairing forest ecosystem services by inducing severe forest disturbances. Bark beetle infestation monitoring is urgently needed for pre-emptive forest management. However, we have a lack of thorough understanding of the physiological responses that occur on trees ...

The Logarithmic Funnel Heap: A Statistically Self-Similar Priority Queue

open access: yes, 2017
The present work contains the design and analysis of a statistically self-similar data structure using linear space and supporting the operations, insert, search, remove, increase-key and decrease-key for a deterministic priority queue in expected O(1 ...

Linear-scaling algorithm for rapid computation of inelastic transitions in the presence of multiple electron scattering [PDF]

open access: yes, 2019
Strong multiple scattering of the probe in scanning transmission electron microscopy (STEM) means image simulations are usually required for quantitative interpretation and analysis of elemental maps produced by electron energy-loss spectroscopy (EELS ...
