Rotating-disk sorptive extraction: effect of the rotation mode of the extraction device on mass transfer efficiency
The extraction device used in rotating-disk sorptive extraction consists of a Teflon disk in which a sorptive phase is fixed on one of its surfaces. Depending on the configuration, the rotation axis of the disk device ...
Differential rotation in rapidly rotating early-type stars. I: motivations for combined spectroscopic and interferometric studies.
(Edp Sciences, 2011-02)
Context. Since the external regions of the envelopes of rapidly rotating early-type stars are unstable to convection, a coupling may exist between the convection and the internal rotation. Aims. We explore what can be ...
On the use of rotational splitting asymmetries to probe the internal rotation profile of stars: Application to beta Cephei stars
(WILEY-V C H VERLAG GMBH, 2010)
Rotationally-split modes can provide valuable information about the internal rotation profile of stars. This has been used for years to infer the internal rotation behavior of the Sun. The present work discusses the potential ...
Effect of Helicity and Rotation on the Free Decay of Turbulent Flows
(American Physical Society, 2009-06)
The self-similar decay of energy in a turbulent flow is studied in direct numerical simulations with and without rotation. Two initial conditions are considered: one nonhelical (mirror symmetric) and one with maximal ...
Experimental and theoretical studies on the rotational barrier of 1-acyl- and 1-alkoxycarbonyl-2-pyrrolines
(Elsevier Science BvAmsterdamHolanda, 2002)
Measurement of the rotational inertia of bodies by using mechanical spectroscopy
(Korean Soc Mechanical Engineers, 2014-10-01)
In this paper, mechanical spectroscopy was used to study the rotational inertia of bodies. In order to verify and show its importance in relation to other techniques, measurements of the internal friction and rotational ...
Evaluation of rotator cuff muscle strength in healthy individuals
(Sociedade Brasileira de Ortopedia e Traumatologia, 2015-06-01)
OBJECTIVE: To compare the strength generated by the rotator muscles of the shoulder joint between the right upper limb and left upper limb among healthy individuals. METHODS: To evaluate the muscle strength of upper limbs ...
Job rotation in assembly lines employing disabled workers
(ELSEVIER SCIENCE BV, 2009)
In this paper we consider the programming of job rotation in the assembly line worker assignment and balancing problem. The motivation for this study comes from the designing of assembly lines in sheltered work centers for ...
Relative rotation number for stochastic systems: dynamical and topological applications
(Taylor & Francis LtdAbingdonInglaterra, 2008)
Statistical study of axial rotation in a type stars with new determination of v sin i
(Universidad Nacional Autónoma de México. Instituto de Astronomía, 2011-10)
We have observed all A type stars of the southern hemisphere brighter than 6.5 mag in order to perform statistical studies of axial rotation. The spectra were obtained at the 2.15 m telescope at CASLEO. We have used the ...
