Large Merger Recoils and Spin Flips From Generic Black-Hole Binaries [PDF]

open access: yes, 2007
We report the first results from evolutions of a generic black-hole binary, i.e. a binary containing unequal mass black holes with misaligned spins. Our configuration, which has a mass ratio of 2:1, consists of an initially non-spinning hole orbiting a ...

The Early and Middle Bronze Age Textile Tools from the Aeolian Islands (Italy)

open access: yesFasciculi Archaeologiae Historicae, 2018
The Aeolian ceramic textile tools dated to the advanced Early and Middle Bronze Age (c. 1600-1250 BC) comprise the only evidence for textile manufacture and are a unique source of information about the technology of textile production used in the Early ...

Modelling the spinning dust emission from dense interstellar clouds

open access: yes, 2011
Electric dipole emission arising from PAHs is often invoked to explain the anomalous microwave emission (AME). This assignation is based on an observed tight correlation between the mid-IR emission of PAHs and the AME; and a good agreement between models

Kahler spinning particles [PDF]

open access: yes, 1994
We construct the U(N) spinning particle theories, which describe particles moving on Kahler spaces. These particles have the same relation to the N=2 string as usual spinning particles have to the NSR string.

The Production of cotton yarns with open-end spinning with excellent quality and cost

open access: yesJournal of Architecture, Art & Humanistic Science, 2020
Open end spinning is one of the final spinning techniques used in the production of cotton yarn, and is characterized by increased production and reduced economic cost, and due to the low spread of open-end yarn technology, and limited production despite

Generalized Killing equations and Taub-NUT spinning space

open access: yes, 1996
The generalized Killing equations for the configuration space of spinning particles (spinning space) are analysed. Simple solutions of the homogeneous part of these equations are expressed in terms of Killing-Yano tensors. The general results are applied

Centrifugally manufactured hollow concrete‐filled steel tubular columns

open access: yesJournal of Civil Engineering and Management, 2007
Hollow concrete‐filled steel tubular elements (H‐CFSTs) represent a type of composite steel‐concrete elements. These elements are usually produced by spinning.

Effect of different cotton material on the yarn produced by the ring spinning

open access: yesJournal of Architecture, Art & Humanistic Science, 2020
The ring spinning is the end of the stages of the cotton yarn spinning by traditional methods Before Yarn winding Process, and is characterized by being one of the best methods used to produce thin yarns with high durability of short fibers, it can also ...

Achieving the most appropriate scientific standards for using compact spinning technique And its effect on the properties of the yarns produce

open access: yesJournal of Architecture, Art & Humanistic Science, 2020
The compact spinning system emerged as a new and innovative generation of ring spinning from here came the idea of research, where three types of Egyptian cotton were selected, Giza 70 super long- Giza 86 long staple and Giza 80 medium length, which are ...

On Neutralization of Charged Black Holes

open access: yes, 2019
For non-spinning, charged (Reissner–Nordström) black holes, the particles with an opposite sign of charge with respect to that of the black hole will be pulled into the black hole by the extra electromagnetic force.
