A New Rolling Model for Three-Roll Rolling Mills

Key Engineering Materials, 2014
During the last 90 years, a lot of works have been published about rolling theories for the two-roll rolling process (2RP). In the last decades, the three-roll process (3RP) has become a significant technique in the production of wire rod and bars, as it allows to cover a wide range of finished dimensions with one pass design, or to realize very close ...

Roll, Kegel roll!

Physik in unserer Zeit, 1997
AbstractWenn Gegenstände ohne erkennbare Energiezufuhr scheinbar eine schiefe Ebene aufwärtsrollen, widerspricht das unmittelbarer Erfahrung und physikalischem Grundwissen. Der aufwärtsrollende Doppelkegel ist ein schönes Beispiel dafür, wie ein Experiment als Lehrmittel Verblüffung bei Laien hervorruft und als etwas abgewandeltes Spielzeug Spaß macht.

Rolling Perception without Rolling Motion

Perception, 2008
The texture of a rolling circle depicts the translational and rotational components of its motion. In the case of a homogeneous circle, however, visual cues to the rotational component of motion are absent. To examine how the visual system resolves undetermined motion cues, optically neutral circles were displaced so that changes in their orientation ...

Rolling back to roll forward: depoliticisation and the extension of government

Policy & Politics, 2014
Premised on the assumption that depoliticisation is a crucial aspect of neo-liberal governmentality, this paper attempts to synergise these two, previously disparate, concepts. Borrowing from Foucault’s theorisation of governmentality and drawing from inclusive definitions of politics/ the political, this paper argues for a reformulation of our ...

Roll, roll, roll your leucocyte gently down the vein.

Immunology Today, 1992
The rapid advances being made in unravelling the biochemistry and function of the three categories of adhesion molecule involved in leucocyte-endothelial-cell interactions, namely selectins, integrins and the Ig super-family molecules, were highlighted at a recent meeting.

Simplified theories of flat rolling—I. The calculation of roll pressure, roll force and roll torque

International Journal of Mechanical Sciences, 1996
Abstract The classical theories of rolling continue to be widely used in practice although finite element methods can provide a more detailed analysis of the deformation during rolling. Both a homogeneous deformation solution and an inhomogeneous method for calculating the roll pressure are reformulated as a development of the classical theories of ...

The USDA Rolls On

JAMA: The Journal of the American Medical Association, 1971
The US Department of Agriculture has announced approval of a fortified cake-like breakfast roll to be used in school breakfast programs and in other government-aided childfeeding programs. The regulations governing the School Breakfast and the Special Food Service Program for Children define a breakfast as follows: (1) one-half pint of fluid whole ...
