Developmental Dynamics, EarlyView.Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Aligned Electrospun Composite Electrolyte. The resurgence of solid‐state Na+ battery, sustained through lithium deficiency and mounting costs, offers an auspicious alternative to solid‐state Li+ battery. This study introduces a nanoarchitectural approach that integrates electrospinning with a simple solution casting technique to develop a mechanically ...

A theory for lateral wing-tip blowing
, 1985 The concept of lateral blowing consists in utilizing thin jets of air, which are ejected in the spanwise direction from slots at the tips of straight and swept wings, or along the leading edges of delta wings, to generate aerodynamic forces without the ...

Papers : An Experimental Study of the Aerodynamic Characteristics Using the Wing - tip Jet Blowing at the Aircraft [PDF]
Journal of the Korean Society for Aeronautical & Space Sciences, 2002 The pressure distributions on a semi-span wing 1/12 scale mode and sic component aerodynamic forces and moments on a complete 1/16 scale advanced trainer model were measured. To reduce wing-tip vortex strength, 3 wing-tip jet slot shaped(forward direction, straigt direction, backward direction) and 3 blowing coefficents (0.004, 0.009, 0.017) were ...

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation
Fire and Materials, EarlyView.ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.

Tracking of Bristle Tip Deflections to Demonstrate Blow-Down in Brush Seals
Volume 8: Heat Transfer: Internal Air Systems; Heat Transfer: Internal Cooling; Industrial and CogenerationAbstract Sealing in gas turbines is paramount to overall performance and efficiency. Brush seals offer superior performance compared to other sealing solutions commonplace in modern turbomachinery. When subjected to a pressure load, a ring of flexible fine wire bristles — fitted at a lay angle to the radial plane — compact to resist the ...

Developing a Typology of Korean Women Leaders' Resistance to Their Token Status in the Workplace
Human Resource Development Quarterly, EarlyView.ABSTRACT Despite remarkable economic development in South Korea (Korea), there are only a few women leaders, and they face challenges in the gendered workplace where organizational constraints and traditional values coexist. In a reanalysis of narratives of Korean women leaders (KWLs), using an ideal‐type analysis as a novel qualitative research method,
