Characterization of the effluents condensated by volatile organic compounds during heat-treated rubberwood process

open access: yesJournal of Wood Science, 2020
Heat treatment was an eco-friendly modification technology for rubberwood, without the addition of chemical reagents into the wood and wood performance has been improved remarkably. Many effluents are generated from heat-treated rubberwood process, which

Genome-wide identification of Jatropha curcas aquaporin genes and the comparative analysis provides insights into the gene family expansion and evolution in Hevea brasiliensis

open access: yesFrontiers in Plant Science, 2016
Aquaporins (AQPs) are channel-forming integral membrane proteins that transport water and other small solutes across biological membranes. Despite the vital role of AQPs, to date, little is known in physic nut (Jatropha curcas L., Euphorbiaceae), an ...

The Growth of PB 260 Clone of Rubber Plant on Peatland

open access: yesSriwijaya Journal of Environment, 2023
The expansion of the area for the cultivation of rubber plants is hampered by the fact that the availability of mineral land has begun to decrease, so many have started to plant rubber on marginal lands such as peatlands.

Unconstrained measurement of lying posture, respiration and heartbeat using a tactile sensor on a bed

open access: yesNihon Kikai Gakkai ronbunshu, 2014
Sleep monitoring provides useful information for keeping a good health condition and detecting diseases. The monitoring system should not interfere with natural sleep, and be an existence that is almost unnoticed by the person being measured, to be used ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Rubber oxygenases [PDF]

open access: yesApplied Microbiology and Biotechnology, 2018
Natural rubber (NR), poly(cis-1,4-isoprene), is used in an industrial scale for more than 100 years. Most of the NR-derived materials are released to the environment as waste or by abrasion of small particles from our tires. Furthermore, compounds with isoprene units in their molecular structures are part of many biomolecules such as terpenoids and ...

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

Optimization of the Production of Rubber Compounds Using Mathematical Models

open access: yesAdvanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Biodegradation of NR Latex-based Materials via a Carbon Dioxide Evolution Method

open access: yesASEAN Journal on Science and Technology for Development, 2017
NR as a natural polymer has biodegradable characteristics and their existence was examined using CO2 evolution methods. The CO2 molecule produced by micro-organism metabolisms in the degradation system was quantified using a conventional acidimetric ...
