Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

Advanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Influência de elementos meteorológicos na dor de pacientes com osteoartrite: revisão da literatura Influence of meteorological elements on osteoarthritis pain: a review of the literature

Revista Brasileira de Reumatologia, 2011
Apesar de frequente a afirmação de que as condições do tempo modificam a intensidade da dor na osteoartrite (OA), essa influência é controversa e de difícil mensuração.

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

The Pressure-Temperature Regime of Iraq during the Period of 1948–2013 [PDF]

Учёные записки Казанского университета: Серия Естественные науки, 2016
We have considered spatiotemporal changes in the pressure-temperature regime at the territory of Iraq and Middle Eastern countries, which is limited by the following geographical coordinates: 27.5–37.5° N, 37.5–50.0° E.

Foliar δ13C Showed No Altitudinal Trend in an Arid Region and Atmospheric Pressure Exerted a Negative Effect on Plant δ13C

Frontiers in Plant Science, 2017
Previous studies have suggested foliar δ13C generally increases with altitude. However, some observations reported no changes or even decreased trends in foliar δ13C.

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

Advanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

The effect of atmospheric pressure and water temperature on the swimming activity of round goby, Neogobius melanostomus (Actinopterygii: Perciformes: Gobiidae) [PDF]

Acta Ichthyologica et Piscatoria, 2018
Background. Atmospheric pressure is one of the most important factors affecting fish activity, but the potential influence on migration patterns of fish lacking a gas bladder is unclear. In this study, we analysed the influence of atmospheric pressure on

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

Advanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

On the short-term prognosis of anticyclonic formations in Vilnius by the hard cosmic ray flux variations / Trumpalaikė anticiklonų formavimosi ties Vilniumi prognozė pagal kietosios kosminės spinduliuotės srauto svyravimus /

Journal of Environmental Engineering and Landscape Management, 2011
Measurements and analyses of variations of the hard cosmic ray flux (HCRF) were carried out in the energy range 1.2–1.6 MeV in Vilnius in 2002–2005, using gamma-spectrometer.

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

Advanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.
