Diversification of early ferns

STEM and diversification

Scott AC.
GSID: y268ITrQOzwJ
J Galtier, AC Scott - Proceedings of the Royal Society of Edinburgh …, 1985 - cambridge.org

… In contrast to this slow early evolution of stem anatomy through Lower Carboniferous time, it is evident from Figure 1 that diversification quickly affected the foliar anatomy of the …

Charcoal: Taphonomy and significance in geology, botany and archaeology

Cultural Transformation in the Geoscience Community AND Program Evaluation

Scott AC.
GSID: vhCInZ2enz8J
AC Scott, F Damblon - Palaeogeography, Palaeoclimatology …, 2010 - Elsevier

Charcoal occurs in the natural environment as either a result of wildfire or volcanic processes. In addition, people may make charcoal, either for domestic or industrial use. Charcoal may be used as a fuel for domestic heating and cooking...

Photocatalytic hydrogen generation enhanced by band gap narrowing and improved charge carrier mobility in AgTaO3 by compensated co-doping.

Physical chemistry chemical physics : PCCP

Li M, Zhang J, Dang W, Cushing SK, Guo D, Wu N, Yin P.
PMID: 23995011
Phys Chem Chem Phys. 2013 Oct 14;15(38):16220-6. doi: 10.1039/c3cp51902c. Epub 2013 Sep 02.

The correlation of the electronic band structure with the photocatalytic activity of AgTaO3 has been studied by simulation and experiments. Doping wide band gap oxide semiconductors usually introduces discrete mid-gap states, which extends the light absorption but has limited...

Re(I) complexes of substituted dppz: a computational and spectroscopic study.

Inorganic chemistry

van der Salm H, Fraser MG, Horvath R, Cameron SA, Barnsley JE, Sun XZ, George MW, Gordon KC.
PMID: 24559053
Inorg Chem. 2014 Mar 17;53(6):3126-40. doi: 10.1021/ic403056g. Epub 2014 Feb 21.

A series of dipyrido[3,2-a:2',3'-c]phenazine (dppz)-based ligands with electron-withdrawing substituents and their [Re(CO)3(L)Cl] and [Re(CO)3(L)(py)]PF6 complexes have been studied using Raman, resonance Raman, and transient resonance Raman (TR(2)) and time-resolved infrared (TRIR) spectroscopic techinques in conjunction with computational chemistry as...

Pedagogical and professional compromises by medical teachers in hospitals.

The clinical teacher

Barrett J, Scott K.
PMID: 25041665
Clin Teach. 2014 Aug;11(5):340-4. doi: 10.1111/tct.12190.

AIM: Following research about workplace constraints reducing the effectiveness of teaching and the motivation to teach, this study sought to understand how medical teachers in hospitals respond to the institutional context for their teaching of medical students.METHODS: Through purposive...

Lanthanide ions as required cofactors for DNA catalysts.

Chemical science

Dokukin V, Silverman SK.
PMID: 23243490
Chem Sci. 2012;3(5):1707-1714. doi: 10.1039/C2SC01067D. Epub 2012 Mar 01.

We report that micromolar concentrations of lanthanide ions can be required cofactors for DNA-hydrolyzing deoxyribozymes. Previous work identified deoxyribozymes that simultaneously require both Zn(2+) and Mn(2+) to achieve DNA-catalyzed DNA hydrolysis (10(12) rate enhancement); a mutant of one such...

Fatal abdominal hemorrhage associated with gallbladder perforation due to large gallstones.

Proceedings (Baylor University. Medical Center)

Soto LR, Levine HR, Celinski SA, Guileyardo JM.
PMID: 24688200
Proc (Bayl Univ Med Cent). 2014 Apr;27(2):131-2. doi: 10.1080/08998280.2014.11929086.

Gallbladder perforation is a relatively uncommon complication of acute cholecystitis and may occur with or without gallstones. Prophylactic cholecystectomy has been recommended for patients with very large stones (>3 cm) due to an increased risk of gallbladder cancer. We...

Group size and visitor numbers predict faecal glucocorticoid concentrations in zoo meerkats.

Royal Society open science

Scott K, Heistermann M, Cant MA, Vitikainen EIK.
PMID: 28484620
R Soc Open Sci. 2017 Apr 19;4(4):161017. doi: 10.1098/rsos.161017. eCollection 2017 Apr.

Measures of physiological stress in zoo animals can give important insights into how they are affected by aspects of their captive environment. We analysed the factors influencing variation in glucocorticoid metabolites in faeces (fGCs) from zoo meerkats as a...

Evaluation of Patient Needs and Patient Navigator Communication about Cervical Cancer Prevention in Appalachian Kentucky.

The Journal of communication

Cohen EL, Scott AM, White CR, Dignan MB.
PMID: 27030783

Few studies describe the way patient navigation processes may address disparities in treatment and follow-up care for medically underserved populations. Using a social ecological framework, we analyzed survey assessments of 519 patients completing a randomized navigation trial in Appalachia...

Sex Differences in Music: A Female Advantage at Recognizing Familiar Melodies.

Frontiers in psychology

Miles SA, Miranda RA, Ullman MT.
PMID: 26973574
Front Psychol. 2016 Mar 01;7:278. doi: 10.3389/fpsyg.2016.00278. eCollection 2016.

Although sex differences have been observed in various cognitive domains, there has been little work examining sex differences in the cognition of music. We tested the prediction that women would be better than men at recognizing familiar melodies, since...
