Predictive Modeling of Activated Tungsten Inert Gas Welding in Grade 91 Steel Using Finite Element Method and Experimental Techniques

steel research international, EarlyView.
This study analyzes the thermal and mechanical behavior of activated tungsten inert gas welding on 4 mm‐thick Grade 91 steel, widely used in high‐temperature applications. Using a combined heat source model, the research predicts weld distortion and residual stress, validated through experiments.

Structural and redundancy performance of power actuated fasteners as direct fastenings in fiber reinforced concrete

Structural Concrete, EarlyView.
Abstract Currently, a wider development of modern concrete mixes in the construction industry is expected, such as concretes with alternative cement types and binders, recycled aggregates, but also concretes with dispersed fiber reinforcement to speed up our work in cutting greenhouse gases and making buildings last longer.

Projectile Velocity and Crater Formation in Water

International Scholastic Journal of Science, 2010
The relationship between the velocity of impact and maximum crater diameter was found for two steel balls dropped into water using 300 fps video. The maximum diameter of the crater was found to be proportional to the impact velocity and independent of ...

Paradigm lost: Venus crater depths and the role of gravity in crater modification [PDF]

Previous to Magellan, a convincing case had been assembled that predicted that complex impact craters on Venus were considerably shallower than their counterparts on Mars, Mercury, the Moon, and perhaps even Earth.

Ultrasonographic features of gastrointestinal ulcerations in cats

Veterinary Record, EarlyView.
Abstract Background Gastrointestinal ulceration in cats can be life threatening due to the risk of perforation and septic peritonitis. However, the ultrasound findings associated with this condition and their diagnostic sensitivities have not been described.

Stability of granular media impacts morphological characteristics under different impact conditions

Open Astronomy
In planetary surfaces, oblique impact events are commonplace, and their study holds significant importance for understanding planetary impact processes and aiding in the design of landers and impactors.

Melt production in large-scale impact events: Calculations of impact-melt volumes and crater scaling [PDF]

Along with an apparent convergence in estimates of impact-melt volumes produced during planetary impact events, intensive efforts at deriving scaling relationships for crater dimensions have also yielded results.

Coral reef fish visual adaptations to a changing world

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Coral reef ecosystems show fluctuations in their prevailing light environment in response to both regular (e.g. between seasons) and more prevalent stochastic events (e.g. human‐induced sediment runoff).
