Implementing classroom physical activity breaks: Associations with student physical activity and classroom behavior

classroom interventions

Carlson JA, Engelberg JK, Cain KL, Conway TL.
GSID: PComclq_15cJ
JA Carlson, JK Engelberg, KL Cain, TL Conway… - Preventive …, 2015 - Elsevier

… A strength of the present study was the ability to study effectiveness of real-world interventions on both student physical activity and classroom behavior, the latter of which has been understudied. The programs were developed and led by school...

OBJECTIVE: To assess the impact of an orthostatic challenge on arterial and venous hemodynamics and its relation to lower leg volume.METHODS: Hemodynamic parameters of 18 healthy subjects (six men; mean age, 38 ± 11 years) were assessed in the...

Thermal diffusivity and nuclear spin relaxation: a continuous wave free precession NMR study.

Journal of magnetic resonance (San Diego, Calif. : 1997)

Venâncio T, Engelsberg M, Azeredo RB, Colnago LA.
PMID: 16616532
J Magn Reson. 2006 Jul;181(1):29-34. doi: 10.1016/j.jmr.2006.03.011. Epub 2006 Apr 17.

Continuous wave free precession (CWFP) nuclear magnetic resonance is capable of yielding quantitative and easily obtainable information concerning the kinetics of processes that change the relaxation rates of the nuclear spins through the action of some external agent. In...

Intermolecular double-quantum coherences in two-dimensional spectra of binary mixtures in solution. The role of diffusion.

The Journal of chemical physics

Engelsberg M, Barros W, Hallwass F.
PMID: 15268092
J Chem Phys. 2004 Jun 08;120(22):10659-65. doi: 10.1063/1.1736631.

Proton NMR two-dimensional 2-D spectra of binary mixtures, obtained with the correlation spectroscopy revamped by asymmetric Z gradient echo detection pulse sequence, were employed to test various assumptions usually adopted to describe the role of diffusion in intermolecular double...

In situ observation of intergranular crack nucleation in a grain boundary controlled austenitic stainless steel.

Journal of microscopy

Rahimi S, Engelberg DL, Duff JA, Marrow TJ.
PMID: 19250463
J Microsc. 2009 Mar;233(3):423-31. doi: 10.1111/j.1365-2818.2009.03133.x.

Grain boundary engineering has been proposed to increase the lifetime performance of sensitized austenitic stainless steel in aggressive environments. Increased microstructure resistance is typically associated with higher fractions of twin (Sigma3) grain boundaries, but there is uncertainty about the...

Morphology and dynamics of craterlike structures created by recoiling elongated particles.

Physical review. E, Statistical, nonlinear, and soft matter physics

Engelsberg M, de Souza RE, Campello SL.
PMID: 22181139
Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Oct;84(4):041311. doi: 10.1103/PhysRevE.84.041311. Epub 2011 Oct 31.

We study the morphology and dynamics of craterlike structures formed when free-falling, randomly oriented, elongated particles bounce off a flat surface in a single particle scattering mode. The origin of a sharply defined rim with its associated structure, the...

Free-evolution kinetics in a high-swelling polymeric hydrogel.

Physical review. E, Statistical, nonlinear, and soft matter physics

Engelsberg M, Barros W.
PMID: 24483476
Phys Rev E Stat Nonlin Soft Matter Phys. 2013 Dec;88(6):062602. doi: 10.1103/PhysRevE.88.062602. Epub 2013 Dec 23.

We employ nuclear magnetic resonance microimaging to study the kinetics of a high-swelling ionic polymer gel. This includes the time evolution of the sphere diameter and also the evolution of the swollen-unswollen boundary. The experimental results for spherical ionic...

Fluid imbibition in paper fibers: precursor front.

Physical review. E, Statistical, nonlinear, and soft matter physics

de Azevedo EN, Alme LR, Engelsberg M, Fossum JO, Dommersnes P.

We employ nuclear magnetic resonance imaging to study water penetration in cylindrical blocks of unsized paper prepared under different molding pressures. From the measured kinetics of the imbibition profiles, we determine the dependence of the effective transport diffusivity upon...

Large Eyelid Defect Repair Using a Free Full-Thickness Eyelid Graft.

Plastic and reconstructive surgery. Global open

Memarzadeh K, Engelsberg K, Sheikh R, Malmsjö M.
PMID: 28831353

Large eyelid full-thickness defects are traditionally repaired using flaps with a blood-supplying pedicle, for the reconstruction of the anterior or posterior lamella or both. This is a 2-stage procedure involving occlusion of vision in the affected eye for 4-8...

Stochastic Model of Breakdown Nucleation under Intense Electric Fields.

Physical review letters

Engelberg EZ, Ashkenazy Y, Assaf M.
PMID: 29694073
Phys Rev Lett. 2018 Mar 23;120(12):124801. doi: 10.1103/PhysRevLett.120.124801.

A plastic response due to dislocation activity under intense electric fields is proposed as a source of breakdown. A model is formulated based on stochastic multiplication and arrest under the stress generated by the field. A critical transition in...
