Before the freeze: otoliths from the Eocene of Seymour Island, Antarctica, reveal dominance of gadiform fishes (Teleostei).

Journal of systematic palaeontology

Schwarzhans W, Mörs T, Engelbrecht A, Reguero M, Kriwet J.
PMID: 28077930
J Syst Palaeontol. 2017;15(2):147-170. doi: 10.1080/14772019.2016.1151958. Epub 2016 Mar 16.

The first record of fossil teleostean otoliths from Antarctica is reported. The fossils were obtained from late Early Eocene shell beds of the La Meseta Formation, Seymour Island that represent the last temperate marine climate phase in Antarctica prior...

Resource limitation, tolerance, and the future of ecological plant classification.

Frontiers in plant science

Craine JM, Engelbrecht BM, Lusk CH, McDowell NG, Poorter H.
PMID: 23115561
Front Plant Sci. 2012 Oct 30;3:246. doi: 10.3389/fpls.2012.00246. eCollection 2012.

Throughout the evolutionary history of plants, drought, shade, and scarcity of nutrients have structured ecosystems and communities globally. Humans have begun to drastically alter the prevalence of these environmental factors with untold consequences for plant communities and ecosystems worldwide....

A literature review on work transitioning of youth with disabilities into competitive employment.

African journal of disability

Engelbrecht M, Shaw L, van Niekerk L.
PMID: 28936411
Afr J Disabil. 2017 Aug 29;6:298. doi: 10.4102/ajod.v6i0.298. eCollection 2017.

BACKGROUND: The marginalisation of youth with disabilities from employment opportunities is evident from literature in as far as they form part of the larger groups 'people with disabilities' and 'youth'. A focused view of programmes that assist youth with...

Intersubband transport in quantum wells in strong magnetic fields mediated by single- and two-electron scattering.

Physical review letters

Kempa K, Zhou Y, Engelbrecht JR, Bakshi P, Ha HI, Moser J, Naughton MJ, Ulrich J, Strasser G, Gornik E, Unterrainer K.
PMID: 12059443
Phys Rev Lett. 2002 Jun 03;88(22):226803. doi: 10.1103/PhysRevLett.88.226803. Epub 2002 May 20.

We show theoretically that in quantum wells subjected to a strong magnetic field the intersubband current peaks at magnetic field values, which reveal the underlying specific intersubband scattering mechanism. We have designed and grown a superlattice structure in which...

Quasiparticle line shape of Sr2RuO4 and its relation to anisotropic transport.

Physical review letters

Wang SC, Yang HB, Sekharan AK, Ding H, Engelbrecht JR, Dai X, Wang Z, Kaminski A, Valla T, Kidd T, Fedorov AV, Johnson PD.
PMID: 15089639
Phys Rev Lett. 2004 Apr 02;92(13):137002. doi: 10.1103/PhysRevLett.92.137002. Epub 2004 Apr 02.

The bulk-representative low-energy spectrum of Sr2RuO4 can be directly measured by angle-resolved photoemission. We find that the quasiparticle spectral line shape of Sr2RuO4 is sensitive to both temperature and momentum. Along the (0,0)-(pi,0) direction, both gamma and beta bands...

A femtosecond fiber laser based on thulium-doped double-clad silica fiber with an internal dispersion compensation is presented that generates pulses at a center wavelength of 1976 nm with an energy of 4.3 nJ and a duration of 1.2 ps....

Single-Frequency ytterbium-doped fiber laser with 26 nm tuning range.

Optics express

Engelbrecht M, Ruehl A, Wandt D, Kracht D.
PMID: 19532707
Opt Express. 2007 Apr 16;15(8):4617-22. doi: 10.1364/oe.15.004617.

A core-pumped ytterbium-doped fiber laser is presented, tunable over 26 nm from 1017 nm to 1043 nm. A diffraction grating pair in Littman-Littrow configuration in the unidirectional ring-cavity provides the wavelength adjustment. The laser resonator with a free spectral...

Family court review

Chavez JM, Lopez A, Englebrecht CM, Viramontez Anguiano RP.
PMID: 24222725
Fam Court Rev. 2012 Oct;50(4). doi: 10.1111/j.1744-1617.2012.01482.x.

The present study examines the effect of unauthorized immigration status on child well-being at a time of elevated immigration rates, economic decline, and unprecedented local lawmaking related to immigration. Immigrant families today are likely to differ from those of...

On Programmed Cell Death in Plasmodium falciparum: Status Quo.

Journal of tropical medicine

Engelbrecht D, Durand PM, Coetzer TL.
PMID: 22287973
J Trop Med. 2012;2012:646534. doi: 10.1155/2012/646534. Epub 2012 Jan 12.

Conflicting arguments and results exist regarding the occurrence and phenotype of programmed cell death (PCD) in the malaria parasite Plasmodium falciparum. Inconsistencies relate mainly to the number and type of PCD markers assessed and the different methodologies used in...

Tricarbonylbis-(triphenyl-phosphane-κP)iridium(I) hexa-fluoridophosphate methanol monosolvate.

Acta crystallographica. Section E, Structure reports online

Engelbrecht I, Visser HG, Roodt A.
PMID: 22969480
