The drawing process behavior was investigated with focus on fiber stretching speed (spinning acceleration) to improve luster quality of fibers. Wet spinning method has a limitation low at high speed. It determined that (1) could be evaluated by arithmetic average ( RΔa ) fibers, which indicated the roughness, and (2) roughness related acceleration through analysis . Spinning measured chasing ma...

In situ surface-enhanced Raman scattering (SERS) spectroscopy is used to identify the key reaction intermediates during plasma-based removal of NO and SO2 under dry wet conditions on Ag nanoparticles. Density functional theory (DFT) calculations are confirm experimental observations by calculating vibrational modes surface-bound intermediate species. Here, we provide spectroscopic evidence that...

Lamellibrachia luymesi and Seepiophila jonesi are co-occurring species of vestimentiferan tubeworms found at hydrocarbon seepage sites on the upper Louisiana slope of the Gulf of Mexico. Like all vestimentiferans, they rely on internal sulfide-oxidizing symbiotic bacteria for nutrition. These symbionts produce hydrogen ions as a byproduct of sulfide oxidation, which the host tubeworm needs to e...

AIM This study evaluates bond strength between dentin and composite using adhesives with different solvents to dry and wet dentin. MATERIALS AND METHODS Ninety bovine incisors were used; the vestibular surfaces were worn by the exposure of an area with a diameter of 4 mm of dentin. The specimens were divided into 6 groups, according to the type of adhesive used and hydratation stals: Group SB...

Ž . The goal of the Project for Intercomparison of Land-surface Parameterization Schemes PILPS is to improve the understanding of the interactions between the atmosphere and the continental surface in climate and weather forecast models. Ž . Ž . In PILPS Phase 4 b , selected schemes are coupled to the Limited Area Prediction System LAPS developed by the Australian Bureau of Meteorology. To faci...

BACKGROUND AND AIMS Parkinsonia aculeata (Caesalpinaceae) is a perennial legume with seeds that have hard-seeded (physical) dormancy and are potentially very long-lived. Seed dormancy is a characteristic that can both help maximize the probability of seedling establishment and spread the risk of recruitment failure across years (bet-hedging). In this study, dormancy-release patterns are describ...

Today, by using half of the oil reserves of the world, natural production of oil has decreased drastically. Gas and water injection for maintaining reservoir pressure is not responsive for oil production.At first, we dispersed silica nanoparticles in low salinity and after two weeks, there was no change in its stability. Then we mixed the nanoparticles in low salinity. After a while, we found o...
