Effect of legume proportion and physiological age on forage quality and the suitability of Agrostis capillaris L. and Festuca rubra L. for silage making

open access: yesPlant, Soil and Environment, 2004
The chemical and physical properties of herbage from low-input grassland usually differ from plant material of intensively managed swards. The experiment in split-plot design with four replicates was carried out to examine, whether legume proportions and

A Feasibility Study on Monitoring Shelf Life of Bottled Natural Fruit Juice Using Laser-Induced Autofluorescence

open access: yesInternational Journal of Optics, 2023
Shelf life of bottled natural fruit juice (BNFJ) provides relevant information on quality and authenticity for consumer protection. However, existing techniques for monitoring the shelf life of BNFJ are destructive and time-consuming.

Laser and electron deflection from transverse asymmetries in laser-plasma accelerators. [PDF]

open access: yes, 2019
We report on the deflection of laser pulses and accelerated electrons in a laser-plasma accelerator (LPA) by the effects of laser pulse front tilt and transverse density gradients.

Molecular screening tools to study Arabidopsis transcription factors

open access: yesFrontiers in Plant Science, 2011
In the model plant Arabidopsis thaliana, more than 2000 genes are estimated to encode transcription factors (TFs), which clearly emphasizes the importance of transcriptional control. Although genomic approaches have generated large TF Open Reading Frame (

Keyhole threshold and morphology in laser melting revealed by ultrahigh-speed x-ray imaging

open access: yesScience, 2019
The key to keyhole formation The formation of keyholes, or vapor-filled depressions, during laser welding presents a large problem for additive manufacturing. Cunningham et al. used high-speed x-ray imaging to take a detailed look at keyhole formation in

Rod Laser – The first laser was a rod laser [PDF]

open access: yesLaser Technik Journal, 2005
Laser technology is relatively young. The first laser was built in 1960 by Maiman at AT&T Labs in the USA. It was a rod-shaped ruby laser, this arrangement having been chosen for its favourable symmetry (Fig. 1). Starting from this device, the technology of solid-state lasers developed rapidly.

Appraising the holistic value of Lenvatinib for radio-iodine refractory differentiated thyroid cancer: A multi-country study applying pragmatic MCDA

open access: yesBMC Cancer, 2017
Background The objective of the study was to reveal through pragmatic MCDA (EVIDEM) the contribution of a broad range of criteria to the value of the orphan drug lenvatinib for radioiodine refractory differentiated thyroid cancer (RR-DTC) in country ...

Laser Shaping and Optimization of the Laser-Plasma Interaction [PDF]

open access: yes, 2000
The physics of energy transfer between the laser and the plasma in laser wakefield accelerators is studied. We find that wake excitation by arbitrary laser shapes can be parameterized using the total pulse energy and pulse depletion length.
