D Reano - The Qualitative Report, 2020 - search.proquest.com

Indigenous research frameworks can be used to effectively engage Indigenous communities and students in Western modern science through transparent and respectful communication. Currently, much of the academic research taking place within Indigenous communities marginalizes Indigenous Knowledge, does not promote...

Pandemic minecrafting: An analysis of the perceptions of and lessons learned from a gamified virtual geology field camp

To mimic the 3D geospatial components of geologic mapping usually spotlighted by field camp, we developed a virtual course based in the sandbox video game Minecraft. Paired with audio/video conferencing and real data, students practiced measuring strike and dip,...

Surface Profiling and Core Evaluation of Aluminum Honeycomb Sandwich Aircraft Panels Using Multi-Frequency Eddy Current Testing.

Sensors (Basel, Switzerland)

Reyno T, Underhill PR, Krause TW, Marsden C, Wowk D.
PMID: 28906434
Sensors (Basel). 2017 Sep 14;17(9). doi: 10.3390/s17092114.

Surface damage on honeycomb aircraft panels is often measured manually, and is therefore subject to variation based on inspection personnel. Eddy current testing (ECT) is sensitive to variations in probe-to-specimen spacing, or lift-off, and is thus promising for high-resolution...

The Relationships between Mental Health Symptoms and Gambling Behavior in the Transition from Adolescence to Emerging Adulthood.

Frontiers in psychology

Sagoe D, Pallesen S, Hanss D, Leino T, Molde H, Mentzoni RA, Torsheim T.

Front Psychol. 2017 Mar 31;8:478. doi: 10.3389/fpsyg.2017.00478. eCollection 2017.

There is a paucity of longitudinal investigations of gambling behavior in the transition from adolescence to emerging adulthood. We conducted a longitudinal investigation of the associations and patterns of change between mental health symptoms and gambling behavior. A representative...

In the title compound, C(22)H(22)N(4), the centroid of the benzene ring is located on an inversion centre. The dihedral angle between the benzene and pyridine rings is 10.94 (5)°. The crystal structure displays weak inter-molecular C-H⋯N hydrogen bonding and...

Hyperquenched glassy water and hyperquenched glassy ethanol probed by single molecule spectroscopy.

Reinot T, Dang NC, Jankowiak R.
PMID: 19249843
J Phys Chem B. 2009 Apr 02;113(13):4303-13. doi: 10.1021/jp808843t.

It is still unclear whether hyperquenched water (i.e., amorphous glassy water) heated to about 140-150 K remains glassy until it crystallizes near 154 K or whether instead it turns into a supercooled and very viscous liquid. It has been...

A typical presentation of a rare cause of obscure gastrointestinal bleeding.

World journal of gastrointestinal endoscopy

Reuter S, Bettenworth D, Mees ST, Neumann J, Beyna T, Domschke W, Wessling J, Ullerich H.
PMID: 21403816
World J Gastrointest Endosc. 2011 Feb 16;3(2):40-5. doi: 10.4253/wjge.v3.i2.40.

A 52-year-old white woman had suffered from intermittent gastrointestinal (GI) bleeding for one year. Upper GI endoscopy, colonoscopy and peroral double-balloon enteroscopy (DBE) did not detect any bleeding source, suggesting obscure GI bleeding. However, in videocapsule endoscopy a jejunal...

Bis(dicyclo-hexyl-phenyl-phosphine)silver(I) nitrate.

Acta crystallographica. Section E, Structure reports online

Burgoyne AR, Meijboom R, Muller A, Omondi B.

Acta Crystallogr Sect E Struct Rep Online. 2010 Apr 10;66:m503-4. doi: 10.1107/S1600536810011724.

The title compound, [Ag(C(18)H(27)P)(2)]NO(3), is a mononuclear salt species in which the Ag atom is coordinated by two phosphine ligands, forming a cation, with the nitrate as the counter-anion, weakly inter-acting with the Ag atom, resulting in Ag⋯O distances...

In the binuclear centrosymmetric title compound, [Ag(2)(NCS)(2)(C(21)H(21)P)(4)]·0.35H(2)O, a pseudo-polymorph of [Ag(2)(NCS)(2)(C(21)H(21)P)(4)]·2CH(3)CN, the Ag atom is coordinated by two phosphine ligands and two bridging thio-cyanate ligands in a distorted tetra-hedral configuration. The crystal structure exhibits inter-molecular C-H⋯π inter-actions.
