Discs gone with the wind?

Investigation of dissipation flow in the urban Canyon

With the wind permanent flow in the cities, obtaining the minimal pollution in the environment is accessible. Different policies have been considered for optimization of cities such as attachment and or reduction of building parts like air-traps, ceiling forms and so on. Due to population growth in cities and the increasing need for resettlement these people in the cities, inevitably, to the hi...

Tensile and Flexural Analysis of a Hybrid Bamboo/Jute Fiber-reinforced Composite with Polyester Matrix as a Sustainable Green Material for Wind Turbine Blades

Recently, there has been a fast growth in research and investigation in the natural fibre composite due to the advantages of these materials, such us low environmental impact, low cost and good mechanical properties compared to synthetic fibre composites. Much effort has gone into increasing the mechanical performance and applications of natural fibes. This paper examines the mechanical propert...

[Ne ii] emission line profiles from photoevaporative disc winds

I model profiles of the [Ne ii] forbidden emission line at 12.81μm, emitted by photoevaporative winds from discs around young, solar-mass stars. The predicted line luminosities (∼ 10L⊙) are consistent with recent data, and the line profiles vary significantly with disc inclination. Edge-on discs show broad (30–40 km s−1) double-peaked profiles, due to the rotation of the disc, while in face-on ...

Through the Looking Glass: Alice and the Constitutional Foundations of the Public Domain

Alice Randall, an African-American woman, was ordered by a government official not to publish her criticism of the romanticization of the Old South, at least not in the words she wanted to use. The official was not one of the many in Congress and the Administration who share a romantic view of the Confederacy. It was a federal judge in Atlanta who told Randall that she could not write her criti...
