Dynamic Reversibility Of Hydrodynamic Focusing For Recycling Sheath Fluid, Nicole N. Hashemi, Peter B. Howell Jr., Jeffrey S. Erickson, Joel P. Golden, Francis S. Ligler
Dynamic Reversibility Of Hydrodynamic Focusing For Recycling Sheath Fluid, Nicole N. Hashemi, Peter B. Howell Jr., Jeffrey S. Erickson, Joel P. Golden, Francis S. Ligler
Nastaran Hashemi
The phenomenon of "unmixing" has been demonstrated in microfluidic mixers, but here we manipulate laminar flow streams back to their original positions in order to extend the operational utility of an analytical device where no mixing is desired. Using grooves in the channel wall, we passively focus a sample stream with two sheath streams to center it in a microchannel for optical analysis. Even though the sample stream is completely surrounded by sheath fluid, reversing the orientation of the grooves in the channel walls returns the sample stream to its original position with respect to the sheath streams. We demonstrate …

Steven P. Bradbury
The objective of this work is to present a critical review of the application of the tissue residue approach (TRA) in ecological risk and/or impact assessment (ERA) of chemical stressors and environmental criteria development. A secondary goal is to develop a framework for integrating the TRA into ecological assessments along with traditional, exposure concentration-based assessment approaches. Although widely recognized for its toxicological appeal, the utility of the TRA in specific applications will depend on numerous factors, such as chemical properties, exposure characteristics, assessment type, availability of tissue residue-response data, and ability to quantify chemical exposure. Therefore, the decision to use …

Meeting The Common Needs Of A More Effective And Efficient Testing And Assessment Paradigm For Chemical Risk Management, Steven P. Bradbury, Vicki Dellarco, Tala Henry, Phil Sayre, Jennifer Seed
Steven P. Bradbury
Significant advances have been made in human health and ecological risk assessment over the last decade. Substantial challenges, however, remain in providing credible scientific information in a timely and efficient manner to support chemical risk assessment and management decisions. A major challenge confronting risk managers is the need for critical information to address risk uncertainties in large chemical inventories such as high- and medium-production-volume industrial chemicals or pesticide inert ingredients. From a strategic and tactical viewpoint, an integrated approach that relies on all existing knowledge and uses a range of methods, including those from emerging and novel technologies, is needed …
[Ni(Tmen)(Acac)][B(Ph)4] A Probe For The Anion Basicity Of Ionic Liquids, Joanna Bartosik, Anja V. Mudring
[Ni(Tmen)(Acac)][B(Ph)4] A Probe For The Anion Basicity Of Ionic Liquids, Joanna Bartosik, Anja V. Mudring
Anja V. Mudring
An optical basicity scale of various ionic liquids (IL) anions has been determined by UV-Vis absorption spectroscopy. The indicator complex [Ni(tmen)(acac)][B(Ph)4] (tmen = tetramethylethylendiamine, acac = acetylacetonate) shows to be a sensitive probe as the position of the 3A2g(F) → 3T1g(F) absorption maximum of square planar to octahedral Ni2+ shifts distinctly depending on the electron donor ability of the respective ionic liquid anion. If the Lewis basicity of the anion becomes stronger a change to a tetrahedral coordination around Ni2+ is observed. Here the 3T1(F) → 3T2(F) and 3T1(F) → 3T1(P) transitions are helpful for monitoring the IL anion basicity. …

Anja V. Mudring
Ionic liquids are shown to be good solvents for elemental sulfur, selenium, phosphorus and tellurium, and can be designed to maximise the solubility of these elements. The presence of the [S3]˙− radical anion in diluted solutions of sulfur in some ionic liquids has been confirmed, and is the origin of their intense blue colour (cf. lapis lazuli).

The most impressive feature of the crystal structure of IrPr6Cl11 is chains of face-sharing {Pr6} octahedra that encapsulate, alternatingly, iridium atoms and chloride ions, according to the formulation {(Ir,Cl)Pr6}Cl10. An alternative description of the structure is the connection of isolated {IrPr6} clusters that are surrounded in a mixed {ZR6}Xi12/{ZR6}Xi8 type by chlorido ligands with a rather complex connectivity, {IrPr6}(Cli−a−a4/3Cla−i−a8/3Cli−a6/2Cla−i6/2)e(Cli−i2/2)f, to a three-dimensional structure of tetragonally packed cluster-complex chains.

The Cognitive Interview: A Meta-Analytic Review And Study Space Analysis Of The Past 25 Years, Amina Memon, Christian A. Meissner, Joanne Fraser
Christian A. Meissner, Ph.D.
The Cognitive Interview (CI) is a well-established protocol for interviewing witnesses. The current article presents a study space analysis of laboratory studies of the CI together with an empirical meta-analysis summarizing the past 25 years of research. The study space comprises 57 published articles (65 experiments) on the CI, providing an assessment of the boundary conditions underlying the analysis and application of this interview protocol. The current meta-analysis includes 46 published articles, including 20 articles published since the last meta-analysis conducted a decade earlier (Ko¨hnken, Milne, Memon, & Bull, 1999). Reassuringly for practitioners, the findings of the original meta-analysis were …

Jelena Bogdanović
Within the Byzantine ecclesiastical tradition, shrines — architectural structures which both enclosed and revealed saints’ remains — defined human bodies within the church space in a remarkable way. Starting in the fourth century, it became customary to exhume and move entire bodies, to permit their fragmentation, and to expose them in architectural settings other than the altar table in the sanctuary space. This practice echoed popular and private piety, which included reporting of miracles of saintly relics that recalled Gospels’ miracles and the hope for corporeal salvation. -- В византийской церковной традиции усыпальницы представляли собой архитектурные конструкции, которые одновременно и …

Art And Architecture: Russia, Jelena Bogdanović
Jelena Bogdanović
Receiving Christianity only in 988/9, the East Slavic Rus' expressly appropriated art and architecture based on Byzantine models and elaborated their own styles. *Kiev, *Novgorod, and *Vladimir (Suzdalia) define the major foci of Rus' accomplishments in the pre-Mongolian period, before the 1230s. Only after the battle at *Kulikovo (1380) did monumental arts revive. And only when Prince Ivan the Great (r. 1462–1505) commissioned architects Aristotele Fioravanti and Alevisio Novi to work in the *Kremlin did the Italian Renaissance significantly influence Russian architecture.

Effects Of Damping Device Nonlinearity On The Performance Of Semiactive Tuned Mass Dampers, C Lindh, Simon Laflamme, Jerome J. Connor
Effects Of Damping Device Nonlinearity On The Performance Of Semiactive Tuned Mass Dampers, C Lindh, Simon Laflamme, Jerome J. Connor
Simon Laflamme
Studies have already demonstrated the successful use of linear semiactive damping devices, such as variable orifice (VO) dampers, for semiactive TMD systems. More recently, nonlinear semiactive damping devices, such as magnetorheological (MR) dampers, have also been shown to be effective for semiactive control of TMDs. Though semiactive dampers differ widely, with responses ranging from linear (VO) to nonlinear (MR), criteria for choosing an optimal semiacive device for a TMD have not been rigorously developed. This paper expands knowledge of semiactive TMD systems by assessing the effect of nonlinearity in the damping device on the effectiveness of a semiactive TMD. This …
Vinyl Cations Substituted With Β Π-Donors Have Triplet Ground States, Arthur Winter, Daniel E. Falvey
Vinyl Cations Substituted With Β Π-Donors Have Triplet Ground States, Arthur Winter, Daniel E. Falvey
Arthur Winter
Computations at the CASPT2, CBS-QB3, and B3LYP levels of theory demonstrate that β-substitution of vinyl cations with π-donors switches the ground state of these ions from the familiar closed-shell singlet state to a carbene-like triplet state similar to the electronic state of triplet phenyl cations. Although the parent vinyl cation is a ground-state singlet species with a very large energy gap to the lowest energy triplet state, substituting the β hydrogens with just one strong π-donor (e.g., NH2, NMe2, OMe) or two moderate π-donors (e.g., F, OH, Ar, vinyl) makes the triplet state the computed ground electronic state. In many …

Size Effect Of Ruthenium Nanoparticles In Catalytic Carbon Monoxide Oxidation, Sang Hoon Joo, Jeong Y. Park, J. Russell Renzas, Derek R. Butcher, Wenyu Huang, Gabor A. Somorjai
Wenyu Huang
Carbon monoxide oxidation over ruthenium catalysts has shown an unusual catalytic behavior. Here we report a particle size effect on CO oxidation over Ru nanoparticle (NP) catalysts. Uniform Ru NPs with a tunable particle size from 2 to 6 nm were synthesized by a polyol reduction of Ru(acac)3 precursor in the presence of poly(vinylpyrrolidone) stabilizer. The measurement of catalytic activity of CO oxidation over two-dimensional Ru NPs arrays under oxidizing reaction conditions (40 Torr CO and 100 Torr O2) showed an activity dependence on the Ru NP size. The CO oxidation activity increases with NP size, and the 6 nm …
The Combat Causal Reasoner Approach To Robotic Control, Michael C. Dorneich, Stephen D. Whitlow, Eric Olson, David Anhalt, Tracy Monteith
The Combat Causal Reasoner Approach To Robotic Control, Michael C. Dorneich, Stephen D. Whitlow, Eric Olson, David Anhalt, Tracy Monteith
Michael C. Dorneich
This paper describes an approach to autonomous robotic control that enables cooperative, tactically correct robotic behaviors that human teammates understand. For maximum effectiveness, unmanned systems (UMSs) must be able to support dismounted warfighters in high-intensity, high-operational-tempo (OPTEMPO) situations without becoming a source of distraction. Current models of robotic control require overt human tasking, limiting robotics to low OPTEMPO tasks. The Combat Causal Reasoner (CCR) proposes to change the paradigm of UMS autonomy by enabling UMSs to cooperate with humans without expecting the UMS to perceive the environment as a human would. CCR uses a Playbook approach to generate responses that …

Electronic And Magnetic Structure Of (Crcl 3 ) 3, M. Grodzicki, B. Mallick, Anja V. Mudring
Anja V. Mudring
Electronic structure calculations in the local spin-density approximation have been carried out on the recently synthesized trimer (CrCl 3 ) 3 exhibiting antiferromagnetic ordering below T N =55 K. The calculated magnetic coupling constant, the paramagnetic Curie temperature, and the decrease of the magnetic moment below T N are well reproduced by the calculations. An interpretation of the spin structure is given that is consistent with all experimental data currently available.

Book Review On The Failure Of Risk Management: Why It’S Broken And How To Fix It, By Douglas W. Hubbard (2009)., Cameron A. Mackenzie
Cameron A. MacKenzie
The title The Failure of Risk Management seemsto imply that risk management is useless. However,the subtitle Why It’s Broken and How to Fix It provides a better description of Douglas Hubbard’s contribution to the field of risk analysis. Hubbard criticizes several risk management methods currently used by a wide variety of organizations but also presents a convincing argument for why probabilistic risk analysis using Monte Carlo simulation is the best approach.

Art And Architecture: Serbian, Jelena Bogdanović
Jelena Bogdanović
From the 9th-century conversion to Christianity until the 11th century, the ecclesiastical art and architecture of the Serbs, both Orthodox and Roman Catholic, shared the concurrent accomplishments of the Croats, Latins, and Greeks. All of these groups cohabited the territories between the rivers Bojana and Cetina in Duklja (Zeta, Montenegro), Zahumlje (Herzegovina), and their littoral. Wall *paintings, donor *portraits, inscriptions in Greek and Latin, and architectural *sculpture on *windows, portals, capitals, *chancel screens, *ciboria, and baptismal fonts, reveal influences of pre-Romanesque, Romanesque, and Byzantine models. Instructive examples come from the 9th-century *rotunda of St. Triphon at Kotor (809?), replaced by …

The forecasts of the International Civil Aviation Organization envisage a growth in world air travel of 5% per annum until 2020. The air traffic in Europe is therefore expected to more than double by 2020. In order to deal with the growth, the European Air Traffic Management (ATM) system will undergo major changes. The envisaged next generation ATM will require new technologies to meet future collaborative decision making, self separation, precision 4D path following, and closer aircraft spacing. The CAMMI (Cognitive Adaptive Man Machine Interface) program addresses human factors priorities in various domains by developing concepts that balance operator workload, …
Forests, Animals, And Ambushes In The Alliterative Morte Arthure, Jeremy Withers
Forests, Animals, And Ambushes In The Alliterative Morte Arthure, Jeremy Withers
Jeremy Withers
In the Alliterative Morte Arthure, the forest is often depicted as an ideal place for ambushing one's enemy. Such persistent attacks lead many warriors in the poem to encounter densely wooded areas with trepidation and even at times with explicit violence towards these places. However, through its use of several arresting locus amoenus passages, the Morte demonstrates alternative ways for soldiers to experience natural landscapes. Rather than suggest that forests are inherently malicious and forbidding places (as many medieval romances have done), the poem suggests that when cleared of an immediate threat of ambush, natural landscapes can be restorative and …
Reversible Addition - Fragmentation Chain Transfer In Microemulsions: Effect Of Chain Transfer Agent Aqueous Solubility, Jennifer M. O'Donnell, Eric W. Kaler
Reversible Addition - Fragmentation Chain Transfer In Microemulsions: Effect Of Chain Transfer Agent Aqueous Solubility, Jennifer M. O'Donnell, Eric W. Kaler
Jennifer M. Heinen
Microemulsion polymerizations are attractive for investigating compartmentalization effects in heterogeneous reversible addition - fragmentation chain transfer (RAFT) polymerizations because the propagating radicals are segregated into surfactant stabilized polymer particles, which drastically reduces the effects of biradical termination, Also, microemulsion polymerizations do not involve the large monomer droplets that are present in emulsion and miniemulsion polymerizations. RAFT microemulsion polymerizations of butyl aery late with a high water solubility chain transfer agent, methyl-2-(O-ethylxanthyl)propionate (MOEP), and a low water solubility chain transfer agent, methyl-2-(O-dodecylxanthyl)propionate (MODP), were investigated to determine the effect of chain transfer agent compartmentalization on the control of the polymerization. The …

Deriving Cursor Control Device Expectations For The Orion Crew Exploration Vehicle, Michael C. Dorneich, Jeff A. Lancaster, Christopher J. Hambin, Olu Olofinboba, Robert E. Demers
Michael C. Dorneich
A unique challenge for the Orion Crew Exploration Vehicle is the need for a novel cursor control device (CCD) that allows the crew to interact with display formats while seated and restrained. Display formats will contain "controllable elements" that will be used for input by astronauts, and will most likely not be laid out in a rectilinear grid. A four-way "caged" castle switch on the CCD was designed to travel only to controllable elements toward decreasing erroneous cursor movements. The ability of the four-way castle to intuitively navigate the cursor from a user perspective is a vital consideration. A cursor …
Cloning And Heterologous Expression Of The Spectinabilin Biosynthetic Gene Cluster From Streptomyces Spectabilis, Zengyi Shao
Cloning And Heterologous Expression Of The Spectinabilin Biosynthetic Gene Cluster From Streptomyces Spectabilis, Zengyi Shao
Zengyi Shao
Spectinabilin is a rare nitrophenyl-substituted polyketide metabolite. Here we report the cloning and heterologous expression of the spectinabilin gene cluster from Streptomyces spectabilis. Unexpectedly, this gene cluster is evolutionarily closer to the aureothin gene cluster than to the spectinabilin gene cluster from Streptomyces orinoci. Moreover, the two nearly identical spectinabilin gene clusters use a distinctly different regulation mechanism.

Seedless Polyol Synthesis And Co Oxidation Activity Of Monodisperse (111)- And (100)-Oriented Rhodium Nanocrystals In Sub-10 Nm Sizes, Yawen Zhang, Michael E. Grass, Wenyu Huang, Gabor A. Somoraji
Wenyu Huang
Monodisperse sub-10 nm (6.5 nm) sized Rh nanocrystals with (111) and (100) surface structures were synthesized by a seedless polyol reduction in ethylene glycol, with poly(vinylpyrrolidone) as a capping ligand. When using [Rh(Ac)2]2 as the metal precursor, (111)-oriented Rh nanopolyhedra containing 76% (111)-twinned hexagons (in 2D projection) were obtained; whereas, when employing RhCl3 as the metal precursor in the presence of alkylammonium bromide, such as tetramethylammonium bromide and trimethyl(tetradecyl)ammonium bromide, (100)-oriented Rh nanocubes were obtained with 85% selectivity. The {100} faces of the Rh nanocrystals are stabilized by chemically adsorbed Br− ions from alkylammonium bromides, which led to (100)-oriented nanocubes. …

Commentary: The Need For A Positive Psychological Approach And Collaborative Effort For Improving Practice In The Interrogation Room, Christian A. Meissner, Maria Hartwig, Melissa B. Russano
Christian A. Meissner, Ph.D.
The White Paper suggests important reforms that will reduce the likelihood of false confessions resulting from police interrogation. The research underlying these suggested reforms has yielded significant advances in our understanding of factors associated with false confessions. As we move forward, we encourage the development of empirically based approaches that provide a viable alternative to current practice. In doing so, we suggest that researchers pursue a positive psychological approach that involves partnering with practitioners to systematically develop interrogative methods that are shown to be more diagnostic. By taking such an approach, we believe that the recommendations offered in the current …

Large-Scale Capacitance Sensor For Health Monitoring Of Civil Structures, Simon Laflamme, Matthias Kollosche, Jerome J. Connor, Guggi Kofod
Simon Laflamme
In this paper, a new type of sensing technique for damage localization on large civil structures is proposed. Specifically, changes in strain are detected using a capacitance sensor built with a soft-stretchable dielectric polymer with attached stretchable metal film electrodes. This sensor is sensitive to a change in strain that causes a change in its capacitance. Fixed to a structure, small changes in the strain can be monitored directly by measuring the change in the capacitance of the unit. This technology allows for simple yet highly accurate measurements of cracks occurring due to deformation, aging, or other structural failures. The …
Archival Information Retrieval: Searching For Evidence In The Relationships Between Documents, Kimberly D. Anderson
Archival Information Retrieval: Searching For Evidence In The Relationships Between Documents, Kimberly D. Anderson
Kimberly D. Anderson
Although archivists have engaged in analog information retrieval (IR) for many decades, automated archival IR is relatively unexamined in either IR or archival literature. The strength of primary source materials lies in their ability to support inference and deduction through the provision of evidence, through both content and context of documents. The hierarchical and spatial structures of archival records may be leveraged in the search for retrieving this kind of relational evidence. The bulk of work done on archival IR has used term matching as the means of retrieval. This is inadequate for research that is concerned with the relationships …
