Effects of rotation in the laser-pulse photoassociation in a thermal gas of atoms
(Spie-int Soc Optical Engineering, 2013-01-01)
Photoassociation is a possible route for the formation of chemical bonds. In this process, the binding of colliding atoms can be induced by means of a laser field. Photoassociation has been studied in the ultracold regime ...
A study of rotational velocity distribution of Be stars
(International Astronomical UnionFlorianópolis, 2013)
Classical Be stars are rapid rotators of spectral type late O to early A and luminosity class V-III, which exhibit Balmer emission lines and often a near infrared excess originating in an equatorially concentrated circumstellar ...
Block rotations within the northern Peruvian Altiplano
(IRD ÉditionsFRA, 2008)
Counterclockwise tectonic rotations in the northern central Andes and clockwise rotations in the southern Central Andes have been systematically reported (see Roperch et al. 2006 and Arriagada et al., 2006 for a recent ...
A finite element approach for predicting the ultimate rotation capacity of RC beams
(2013-07-15)
This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
A genetic algorithm for crop rotation
(2012-06-13)
In the last few years, crop rotation has gained attention due to its economic, environmental and social importance which explains why it can be highly beneficial for farmers. This paper presents a mathematical model for ...
Ergonomics and Regulation: The Case of Job Rotation in a Brazilian Slaughterhouse
(2019-01-01)
In April 2013, Regulatory Standard 36 was published in Brazil, concerning health and safety at work in slaughtering and meat processing companies, aiming to establish, among other things, standards for the implementation ...
Stepping motor driven constant-shear-rate rotating viscometer
(2004-10-08)
Despite the frequent use of stepping motors in robotics, automation and in a variety of precision instruments, they can hardly be found in rotational viscometers. This paper proposes the use of a stepping motor to drive ...
Influence of Angular Thrust in the Measurement of Torque in the SPT-T
(Ios Press, 2015-01-01)
Skin friction of piles can be calculated with the torque measurement in the Standard Penetration Test, SPT-T, proposed by [1]. The purpose of this paper is to provide understating of the influence of angular thrust and ...
Observational effects of stellar rotation on Be stars' disks
(National Observatory of AthensRhodes, 2013)
Be stars are known to be fast rotators. At high rotation rates a profound modification of the radiation field reaching the circumstellar environment is expected. The origin of this modification is the decrease of the ...
Semi-analytical study of the rotational motion stability of artificial satellites using quaternions
(Iop Publishing Ltd, 2013-01-01)
This study at aims performing the stability analysis of the rotational motion to artificial satellites using quaternions to describe the satellite attitude (orientation on the space). In the system of rotational motion ...
