Determination of the physical and mechanical properties of wood-cement boards produced with Pinus spp and pozzolans waste

open access: yesMaderas: Ciencia y Tecnología, 2020
The objective of this research was to evaluate the physical-mechanical properties of wood-cement boards produced with waste particles of Pinus spp. and sufficient levels of pozzolans to assimilate all Ca(OH)2 produced during the hydration reactions of ...

Difficulty of internal bond prediction of particleboard using the density profile

open access: yesJournal of Wood Science, 2021
The relationship between density profile and internal bond (IB) of commercial particleboards was investigated. Minimum density was theoretically related to the IB, but the correlation coefficient between them was low at 0.435.

Using Bootstrapping to Determine Artificial Neural Network Confidence Intervals—Case Study of Particleboard Internal Bond Determined from Production Data

open access: yesApplied Sciences
Tensile strength perpendicular to the plane of the board (also known as the Internal Bond—IB), determined in accordance with standard EN 319, is one of the most critical properties in particleboard quality control.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Study of lattice dynamics of silicon

open access: yesBibechana, 2012
Lattice dynamics of Si has been investigated by using a Urey-Bradley Valence Force Field (UVFF) model which is a phenomenological model. In this model following interactions are taken into account: (i) the central force due to bond-stretching (ii) the ...

Do ESG scores have incremental information value on the primary bond market?——evidence from China

open access: yesFrontiers in Environmental Science, 2023
ESG scores are essential information tools in the capital market, but prior study has not fully discussed the effect and internal mechanism of ESG scores on bond investors’ risk pricing in the primary market.

Spread Overreaction in International Bond Markets [PDF]

open access: yesSSRN Electronic Journal, 1998
This paper applies the Campbell-Shiller (1987) methodology to a study of the joint behaviour of a three-month and a five-year government yield in the United States, Canada, the United Kingdom, Germany and Japan. The period studied is for most countries the mid-1970s to the third quarter of 1997.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...
