Maritime pine (Pinus pinaster) sawdust was used to produce liquefied wood by the polyhydric method with acid catalysis. The process was optimized to produce the highest amount of liquefied wood. Wood liquefied at 160oC for 90 min was used in the adhesion tests. The bond strength of veneer glued with ureaformaldehyde and melamine-urea-formaldehyde resins and several mixtures of liquefied wood wi...

Dendrocalamus latiflorus Munro (ma bamboo) was liquefied in phenol or in polyethylene glycol/glycerol cosolvent, with H2SO4 as a catalyst. The liquefied bamboo was reacted with bisphenol-A and epichlorohydrin to prepare copolymer epoxy resins. The thermal properties of resins during and after curing were investigated by differential scanning calorimetry (DSC) and dynamic mechanical analysis (DM...

The propagation of solidified zones in the course of subaqueous liquefied sediment flow is theoretically discussed. The coupled systems of Navier-Stokes equations and consolidation equation are numerically solved under moving boundary conditions, with consideration of the concurrent evolutions of the flow surface as well as of the internally formed interface between the fluid and solidified zon...

BACKGROUND & OBJECTIVES Sensitivity of Ziehl-Neelsen (ZN) method is known to be low for liquefied sputum smears. Information on the ZN sensitivity for centrifuged deposit smears is not known. This study was carried out to determine the sensitivity of ZN method for acid fast bacilli (AFB) in centrifuged deposit smears and liquefied sputum smears made from sputum samples transported in cetyl-pyri...

The capacity degradation of bucket foundation in liquefied sand layer under cyclic loads such as equivalent dynamic ice-induced loads is studied. A simplified numerical model of liquefied sand layer has been presented based on the dynamic centrifuge experiment results. The ice-induced dynamic loads are modeled as equivalent sine cyclic loads, the liquefaction degree in different position of san...

Microwave-assisted liquefaction of rape straw in methanol was conducted to collect the liquefied residues for the extraction of cellulose nanocrystals (CNCs). The liquefied residue with content of 23.44% from 180C/7.5min was used to fibrillate CNCs with dilute alkali (2% NaOH) and hydrogen peroxide (5% H 2 O 2 ) treatments, followed by ultrasonication for 15min. The FT-IR spectra and SEM images...

objective: to evaluate the efficacy of in vitro sperm activation (isa) using non-liquefied versus liquefied asthenozoospermic semen samples for improvement of sperm parameters. materials and methods: fifty six oligoasthenozoospermic (oa) patients (age range: 22-44 years; mean: 32.089 years) were enrolled in this study. oa patients were classified according to type of infertility. also, duration...

Bamboo raw feedstocks with large particle size (20−80 mesh) were subjected to a microwave liquefaction system, and the liquefied products were separated into biopolyols and liquefied residues. Biopolyols were first analyzed by gas chromatography mass spectrometry (GC−MS), and the main components were sugar derivatives with 2−4 hydroxyl groups and phenolic compounds derived from lignin. The resi...
