Microscopic identification of changes in beech (Fagus sylvatica L.) and pine (Pinus sylvestris L.) cell structure after drying using high-frequency energy of the microwave band

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
High-frequency energy transfer represents a progressive technology with an increasing range of industrial application. One of the main advantages of microwave technology is the volumetric principle of energy transfer. Based on this fact, the gradients of

Structure of F2(-) centers in K2YF5 and their relation to thermoluminescence below room temperature [PDF]

, 2009
X-ray irradiation at 77 K produces signals from several trapped hole and/or electron centers in the electron-paramagnetic-resonance (EPR) spectra of rare-earth-doped K2YF5.

Seasonal Turbidity Linked to Physical Dynamics in a Deep Lake Following the Catastrophic 2014 Mount Polley Mine Tailings Spill

Water Resources Research, Volume 56, Issue 8, August 2020., 2020
Abstract The catastrophic August 2014 Mount Polley tailings spill, the second largest ever documented, sent ~18 Mm3 of waste plunging to the bottom of the >100 m deep West Basin of Quesnel Lake, British Columbia, a critical West Coast salmon habitat. To understand the impact of the spill on the lake, including the fate of suspended solids, we examine ...

Influence of microwave plasticization, high temperature treatment and areal compression on modulus of elasticity and bending strength perpendicular to the gain in radial direction at Spruce (Picea abies (L.) Karst.)

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2009
Nowadays wood modification is very-discussed and its importance is growing up. Wood plasticization alias a temporary change of wood properties makes subsequent processing possible.

Seafloor geodesy unveils seismogenesis of large subduction earthquakes in Mexico. [PDF]

Sci Adv
Based on measurements of near-trench deformations of the oceanic and overriding plates, in this investigation, we elucidate the tectonic and mechanical processes leading to the Mw7.0 (moment magnitude of 7.0) Acapulco, Mexico, earthquake in 2021.

Numerical Evaluation of Reinforced Concrete Columns Retrofitted with FRP for Blast Mitigation

Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020
Fiber reinforced polymer (FRP) material is commonly applied in retrofitting structures due to the advantages of high strength and well corrosion resistance. Previous studies indicated that retrofitting with FRP sheet was an effective way for protecting the existing structures to resist the blast loads, but little research made comprehensive comparison ...

(INVITED) Ultraviolet cross-luminescence in ternary chlorides of alkali and alkaline-earth metals

Optical Materials: X, 2021
After the discovery of a cross-luminescence (CL) in BaF2 in 1982, a large number of CL scintillators were investigated. However, no CL scintillator superior to BaF2 has been discovered, and the research of CL scintillators has subsided.

Electron paramagnetic resonance study of Eu2+ centers in melt-grown CsBr single crystals [PDF]

, 2012
The structure of Eu2+ monomer centers in CsBr single crystals is investigated using electron paramagnetic resonance (EPR) spectroscopy. These centers are produced by heating the melt-grown crystals above 600 K in vacuum followed by a rapid quench to room
