Influence of Ultrasonic‐Assisted Milling on Surface Integrity and Fatigue Strength of a Low Alloy Steel

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The milling process significantly influences the surface integrity of metallic components through machining induced near‐surface residual stresses. Modern hybrid machining processes, such as ultrasonic‐assisted milling (USAM), offer the potential to induce beneficial near‐surface compressive residual stresses compared to the near‐surface ...

Safety and Efficacy of LockeT Suture Retention Device for Large‐Bore Venous Access Closure

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Electrophysiology (EP) procedures increasingly require large‐bore venous access (LBVA), which is associated with a higher risk of vascular complications. While vascular closure devices (VCDs) are well established for arterial access, data on venous closure—particularly for LBVA—remain limited.

Drill-string nonlinear dynamics accounting for the drilling fluid

, 2009
The influence of the drilling fluid (or mud) on the drill-string dynamics is analyzed in this paper. Usually the presence of the fluid is not taken into account in the analysis of the nonlinear dynamics of a drill-string. The aim of this paper is to investigate how the fluid affects this dynamics using a simplified fluid-structure interaction model ...

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Carbon and nitrogen contents depends on macroalgal species, their tissue section, and development stage

Phycological Research, EarlyView.
SUMMARY Assessing the potential for macroalgae to function as a carbon sink (blue carbon) and nitrogen (N) assimilation is under intensive investigation. The content of elemental carbon (C) and N in macroalgae is the best indicator of their potential; however, with respect to the thallus, C and N content varies in space and time.

Flaring reduction solutions: How Norway, the US and Russia regulate flaring to mitigate black carbon emissions in the Arctic

Review of European, Comparative &International Environmental Law, EarlyView.
Abstract Gas flaring is a common practice for burning excessive gas during oil and gas production. Flaring results in the release of various pollutants that contribute to climate change. In the Arctic, black carbon emissions released from flaring, in and near the region, contribute to local warming.
