The Double Asteroid Redirection Test (DART) is a spacecraft that will impact the smaller body of the binary asteroid Didymos. As a technology demonstration, this will be the first time a kinetic impactor is used to perturb the motion of a near earth

In situthermal studies and post-weld mechanical properties of friction stir welds in age hardenable aluminium alloys

Autor: W. J. Arbegast, R. J. Steel, T. W. Nelson

Publikováno v: Science and Technology of Welding and Joining. 8:283-288

The 'quench sensitivity' of various friction stir welded (FSW) aluminium alloys were investigated. Cooling rates of FSW were altered by utilising various active (weld side) and passive (anvil side) cooling/heating conditions. Media used included a ch

Effects of Friction Stir Processing on the Microstructure and Mechanical Properties of Fusion Welded 304L Stainless Steel

Autor: C. D. Sorensen, T. W. Nelson, M. Posada, C. J. Sterling

A variation of FSW, friction stir processing (FSP), has been used to modify selected regions of materials to enhance specific properties while eliminating fusion welding defects such as porosity, cracking, and the cast microstructure. The combination

Quantitative observations on feeding behavior inSaguinus geoffroyi (callithricidae, primates)

Autor: T. W. Nelson

Publikováno v: Primates. 16:223-226

Feeding behavior of a six-animal group of marmosets,Saguinus geoffroyi, was observed under field conditions in the Panama Canal Zone. The order of feeding was recorded as the marked animals fed from a limited access food source. A combined distributi

The origin of petroleum

Autor: T. W. Nelson

Publikováno v: Journal of Chemical Education. 31:399

Theories regarding the origin of oil are many and conflicting, but they must be in agreement with certain geological conditions established by widespread observations.
