Comparison of sea‐ice draft data acquired on submarine cruises between 1993 and 1997 with similar 1958 1976 indicates that the mean ice at end melt season has decreased by about 1.3 m in most deep water portion Arctic Ocean, from 3.1 1958–1976 to 1.8 1990s. The decrease is greater central eastern than Beaufort Chukchi seas. Preliminary evidence cover continued become thinner some regions during
Sea ice thickness is an important parameter in the surface energy exchange and mass balance of polar oceans. Remote sensing offers opportunity to monitor thin routinely. We combine measurements temperature from advanced very high resolution radiometer (AVHRR) with a thermodynamic growth model estimate its distribution during cold season. In Beaufort area perennial we find that ice, up meter thick, had concentration 18% December 1990 3% April 1991; concentrations near edge Greenland range 20%...
<h3>Importance</h3> Postoperative ileus is common after abdominal surgery, and small clinical studies have reported that intraoperative administration of dexmedetomidine may be associated with improvements in postoperative gastrointestinal function. However, findings been inconsistent study samples small. Further examination the effects on function needed. <h3>Objective</h3> To evaluate intravenous vs placebo among older patients undergoing surgery. <h3>Design, Setting, Participants</h3>...
To enhance the various properties of polyvinyl alcohol (PVA), varying concentrations carboxy-functionalized graphene (CFG) were employed in preparation CFG/PVA nanocomposite films. FTIR and XRD analyses revealed that CFG, contrast to graphene, not only possesses carboxylic acid group but also exhibits higher crystallinity. Mechanical testing indicated a notable superiority CFG addition over with optimal mechanical such as tensile yield strengths being achieved at 3% concentration. Relative...
Submarine sonar data collected in the central Arctic Basin during middle and late summer were used to examine differences sea ice thickness distribution function g ( h ) between periods 1958–1970 1993–1997. Cruises former period made July August, whereas 1993–1997 cruises September October. Seasonal correction was applied adjust for thickness. While drafts from only seven submarine somewhat spatially limited, results indicate that fractional area covered by open water first‐year increased...
Cellulose (8%) can be dissolved in tetrabutylammonium acetate (TBAA) with dimethyl sulfoxide (DMSO) and crown ether (18-crown-6) within 5 min at 40 °C without any pretreatment.
Graphene that consists of less than 10 layers is expensive; moreover, it tends to agglomerate. These disadvantages restrict its utility. In this regard, the present study aimed reduce number a functionalized graphene (FG) with 10-30 by using an ultrasonic processor. We prepared nanocomposite films polyvinyl alcohol (PVA) incorporated FG simple hydrothermal method and dispersion. Oxygen transmission rate water vapor permeability were considerably increased on account modifying PVA FG....
Polypropylene (PP) has some disadvantages when used in food packaging: PP does not have antibacterial properties, and it exhibits low barrier properties. In this study, nanocomposites of filled with different amounts silver-decorated multiwalled carbon nanotubes (MWCNTs-Ag) were fabricated. A new nanomaterial silver had the advantage providing capabilities, contribution MWCNTs was to reinforce mechanical melt-blended MWCNTs-Ag, but ensuing problem poor interfacial interaction fillers polymer...
A co-dispersion of cellulose and MWCNTs was prepared in a TBAA/DMSO solvent mixture then used to prepare composite fibers.
The accuracy of Arctic sea ice surface temperatures T s derived from advanced very high resolution radiometer (AVHRR) thermal channels is evaluated in the cold seasons by comparing them with air drifting buoys and stations. We use three different estimates satellite temperatures, a direct estimate AVHRR channel 4 only correction for snow emissivity but not atmosphere, single‐channel regression , Key Haefliger's (1992) polar multichannel algorithm. find no measurable bias any these few...
This work determined that southern yellow pine wood can almost be completely dissolved in the quaternary ammonium ionic liquid tetrabutylammonium acetate with dimethyl sulfoxide (in a 2:8 mass ratio), after minimal grinding, upon heating at 85 °C for three dissolution/reconstitution cycles, each 1.5 h. Approximately 34.6% of native lignin and 67.4% carbohydrates present original subsequently extracted, respectively, were assessed. A gradual decrease increased extraction cycles resulted...
A novel, efficient, and direct blend of solvents, tetrabutylammonium acetate/dimethyl sulfoxide (TBAA/DMSO), was used for the dissolution regeneration bamboo pulp.Regenerated fibers were successfully prepared by a wet spinning process.The pulp without any pretreatment readily soluble in solvent under mild conditions.The process observed using confocal laser scanning microscope (CLSM).Rheological properties cellulose solutions at various concentrations investigated.The regenerated coagulation...
Microcrystalline cellulose grafted polycaprolactone (MCC-g-PCL) was successfully synthesized by ring-opening copolymerization catalyzed 4-dimethylaminopyridine in a dual tetrabutylammonium acetate/dimethyl sulfoxide solvent system. A novel ultraviolet-shielding film based on MCC-g-PCL prepared introducing graphene oxide (GO). The results obtained showed that the introduction of GO not only obviously influenced inherent structure but remarkably changed surface morphology composite film....
