Student-directed problem-based learning in general practice and public health medicine.

Medical education

Usherwood T, Joesbury H, Hannay D.
PMID: 1758319
Med Educ. 1991 Sep;25(5):421-9. doi: 10.1111/j.1365-2923.1991.tb00090.x.

The development and implementation are described of a new 6-week course in general practice and public health medicine for final-year medical students. This course is based on the principles of student-directed problem-based learning in small groups and makes substantial...

A double vacuum window mechanism for space-borne applications.

The Review of scientific instruments

Zilic K, Aboobaker A, Aubin F, Geach C, Hanany S, Jarosik N, Milligan M, Sagiv I.
PMID: 28456220
Rev Sci Instrum. 2017 Apr;88(4):045112. doi: 10.1063/1.4981814.

We present a vacuum window mechanism that is useful for applications requiring two different vacuum windows in series, with one of them movable and resealable. Such applications include space borne instruments that can benefit from a thin vacuum window...

Crystal structure of (1S,2S,2'R,3a'S,5R)-2'-[(5-bromo-1H-indol-3-yl)meth-yl]-2-isopropyl-5,5'-dimethyl-dihydro-2'H-spiro-[cyclo-hexane-1,6'-imidazo[1,5-b]isoxazol]-4'(5'H)-one.

In the title compound, C24H32BrN3O2, the six-membered cyclo-hexane ring adopts a chair conformation and the isoxasolidine ring adopts a twisted conformation. The mol-ecule has five chiral centres and the absolute configuration has been determined in this analysis. The mol-ecular...

An examination of the effect of decaying exponential pulse electric fields on cell mortality in murine spleenocytes, hybridomas, and human natural killer cells.

Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual Conference

Kandlikar S, Oakley B, Hanna D, Stryker G.
PMID: 17270818
Conf Proc IEEE Eng Med Biol Soc. 2004;2004:2643-6. doi: 10.1109/IEMBS.2004.1403758.

This work describes the percentage cell lysis produced by exponentially decaying electric field pulses of varying amplitudes and time constants. Three different cell types were examined: murine spleenocytes, hybridomas, and human natural killer. Cells were cultured and separate samples...

Modeling HIV-1 dynamics and the effects of decreasing activated infected T-cell count by filtration.

Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual Conference

Spagnuolo AM, Hanna DM, Lindsey W, Stryker GA.
PMID: 17271779
Conf Proc IEEE Eng Med Biol Soc. 2004;2006:722-5. doi: 10.1109/IEMBS.2004.1403260.

Over the past 10 years mathematical models have been developed using differential equations for the progression of HIV-1 to AIDS in an infected patient. Additional terms and formulations are presented over time, as the disease is better understood. Experimentation...

Ring-doped cladding-pumped single-mode three-level fiber laser.

Optics letters

Nilsson J, Minelly JD, Paschotta R, Tropper AC, Hanna DC.
PMID: 18084510
Opt Lett. 1998 Mar 01;23(5):355-7. doi: 10.1364/ol.23.000355.

We propose and theoretically analyze three-level cladding-pumped fiber lasers in which the laser-active dopant is placed in a ring around a single-mode core. A ring-doped laser can work efficiently at wavelengths with strong small-signal absorption. This is otherwise difficult...

Wavelength-tunable high-power picosecond pulses from a fiber-pumped diode-seeded high-gain parametric amplifier.

Optics letters

Britton PE, Broderick NG, Richardson DJ, Smith PG, Ross GW, Hanna DC.
PMID: 18091853
Opt Lett. 1998 Oct 15;23(20):1588-90. doi: 10.1364/ol.23.001588.

We describe a high-gain optical parametric amplifier (OPA) and optical parametric generator (OPG) system pumped by a fiber chirped-pulse amplification source based on novel large-mode-area fiber components. 45-nJ OPG thresholds and 34% pump-signal conversion efficiencies are obtained for ~4-ps...

2-W Ho:YAG laser intracavity pumped by a diode-pumped Tm:YAG laser.

Optics letters

Bollig C, Hayward RA, Clarkson WA, Hanna DC.
PMID: 18091905
Opt Lett. 1998 Nov 15;23(22):1757-9. doi: 10.1364/ol.23.001757.

Efficient room-temperature operation of a Ho:YAG laser, intracavity pumped by a diode-bar-pumped Tm:YAG laser, is reported. At rod mount temperatures of 10 degrees C, for both the Tm:YAG and the Ho:YAG rods, we obtained 2.1 W of output at...

Identification of frankia strains by two-dimensional polyacrylamide gel electrophoresis.

Applied and environmental microbiology

Benson DR, Buchholz SE, Hanna DG.
PMID: 16346488
Appl Environ Microbiol. 1984 Mar;47(3):489-94. doi: 10.1128/aem.47.3.489-494.1984.

Fifteen Frankia strains from five different plant species were analyzed by two-dimensional polyacryl-amide gel electrophoresis to determine their relatedness by comparing the polypeptide patterns obtained. Three major subgroups (A, C, and D) were found in the Alnus-Comptonia-Myrica cross-inoculation group....
