Standoff detection of nitrotoluenes using 213-nm amplified spontaneous emission from nitric oxide.

Analytical and bioanalytical chemistry

Arnold B, Kelly L, Oleske JB, Schill A.
PMID: 19649618
Anal Bioanal Chem. 2009 Sep;395(2):349-55. doi: 10.1007/s00216-009-2990-7. Epub 2009 Aug 01.

A method of standoff detection based on the observation of laser-induced fluorescence-amplified spontaneous emission (LIF-ASE) is described. LIF-ASE generates uniaxial intensity distributions of the observed fluorescence with the majority of intensity propagating along the excitation axis in both the...

Characterization of intracellular accumulation of poly-beta-hydroxybutyrate (PHB) in individual cells of Alcaligenes eutrophus H16 by flow cytometry.

Biotechnology and bioengineering

Srienc F, Arnold B, Bailey JE.
PMID: 18553486
Biotechnol Bioeng. 1984 Aug;26(8):982-7. doi: 10.1002/bit.260260824.

Poly-beta-hydroxybutyrate (PHB) accumulates in individual cells of Alcaligenes eutrophus in the form of refractile bodies which alter the light-scattering properties of individual cells. Flow cytometry has been applied to measure the distributions of single-cell light-scattering intensity in Alc. eutrophus...

Tool feed influence on the machinability of CO(2) laser optics.

Applied optics

Arnold JB, Steger PJ, Saito TT.
PMID: 20154919
Appl Opt. 1975 Aug 01;14(8):1777-82. doi: 10.1364/AO.14.001777.

Influence of tool feed on reflectivity of diamond-machined surfaces was evaluated using materials (gold, silver, and copper) from which CO(2) laser optics are primarily produced. Fifteen specimens were machined by holding all machining parameters constant, except tool feed. Tool...

Neuromuscular Response Characteristics in Men and Women After Knee Perturbation in a Single-Leg, Weight-Bearing Stance.

Journal of athletic training

Shultz SJ, Perrin DH, Adams MJ, Arnold BL, Gansneder BM, Granata KP.
PMID: 12937513
J Athl Train. 2001 Mar;36(1):37-43.

OBJECTIVE: We examined whether muscle response times and activation patterns in the lower extremity differed between men and women in response to a rotational knee perturbation while standing in a single-leg, weight-bearing stance. DESIGN AND SETTING: We used a...

Mapping hospice patients' perception and verbal communication of end-of-life needs: an exploratory mixed methods inquiry.

BMC palliative care

Arnold BL.
PMID: 21272318
BMC Palliat Care. 2011 Jan 27;10:1. doi: 10.1186/1472-684X-10-1.

BACKGROUND: Comprehensive "Total Pain" assessments of patients' end-of-life needs are critical for providing improved patient-clinician communication, assessing needs, and offering high quality palliative care. However, patients' needs-based research methodologies and findings remain highly diverse with their lack of consensus...

Cluster-randomised controlled trials of individual and combined water, sanitation, hygiene and nutritional interventions in rural Bangladesh and Kenya: the WASH Benefits study design and rationale.

BMJ open

Arnold BF, Null C, Luby SP, Unicomb L, Stewart CP, Dewey KG, Ahmed T, Ashraf S, Christensen G, Clasen T, Dentz HN, Fernald LC, Haque R, Hubbard AE, Kariger P, Leontsini E, Lin A, Njenga SM, Pickering AJ, Ram PK, Tofail F, Winch PJ, Colford JM.
PMID: 23996605
BMJ Open. 2013 Aug 30;3(8):e003476. doi: 10.1136/bmjopen-2013-003476.

INTRODUCTION: Enteric infections are common during the first years of life in low-income countries and contribute to growth faltering with long-term impairment of health and development. Water quality, sanitation, handwashing and nutritional interventions can independently reduce enteric infections and...

Ultrastable nanostructured polymer glasses.

Nature materials

Guo Y, Morozov A, Schneider D, Chung JW, Zhang C, Waldmann M, Yao N, Fytas G, Arnold CB, Priestley RD.
PMID: 22306770
Nat Mater. 2012 Feb 05;11(4):337-43. doi: 10.1038/nmat3234.

Owing to the kinetic nature of the glass transition, the ability to significantly alter the properties of amorphous solids by the typical routes to the vitreous state is restricted. For instance, an order of magnitude change in the cooling...

Key factors in work engagement and job motivation of teaching faculty at a university medical centre.

Perspectives on medical education

van den Berg BA, Bakker AB, Ten Cate TJ.
PMID: 24037742
Perspect Med Educ. 2013 Nov;2(5):264-75. doi: 10.1007/s40037-013-0080-1.

This study reports about teacher motivation and work engagement in a Dutch University Medical Centre (UMC). We examined factors affecting the motivation for teaching in a UMC, the engagement of UMC Utrecht teaching faculty in their work, and their...

Baryon-number violation at the Superconducting Super Collider? Recent claims reexamined.

Fostering Flexibility in the New World of Work: A Model of Time-Spatial Job Crafting.

Frontiers in psychology

Wessels C, Schippers MC, Stegmann S, Bakker AB, van Baalen PJ, Proper KI.
PMID: 30941072
Front Psychol. 2019 Mar 19;10:505. doi: 10.3389/fpsyg.2019.00505. eCollection 2019.

In today's "new world of work," knowledge workers are often given considerable flexibility regarding where and when to work (i.e., time-spatial flexibility) and this has become a popular approach to redesigning work. Whilst the adoption of such practices is...

Impulsively Induced Jets from Viscoelastic Films for High-Resolution Printing.

Physical review letters

Turkoz E, Perazzo A, Kim H, Stone HA, Arnold CB.
PMID: 29542955
Phys Rev Lett. 2018 Feb 16;120(7):074501. doi: 10.1103/PhysRevLett.120.074501.

Understanding jet formation from non-Newtonian fluids is important for improving the quality of various printing and dispensing techniques. Here, we use a laser-based nozzleless method to investigate impulsively formed jets of non-Newtonian fluids. Experiments with a time-resolved imaging setup...

Sci Adv. 2019 Mar 08;5(3):eaau8044. doi: 10.1126/sciadv.aau8044. eCollection 2019 Mar.

Under rapid high-temperature, high-pressure loading, lattices exhibit complex elastic-inelastic responses. The dynamics of these responses are challenging to measure experimentally because of high sample density and extremely small relevant spatial and temporal scales. Here, we use an x-ray free-electron...
