Interior Colour Rendering Of Daylight Transmitted Through A Suspended Particle Device Switchable Glazing, Aritra Ghosh, Brian Norton

Articles

The colour rendering index (CRI) and correlated colour temperature (CCT) of daylight change upon transmission through a variable transmittance suspended particle device (SPD) switchable glazing.

The luminous transmittance of SPD glazing was found to vary from 0.02 to 0.55 in opaque and transparent state respectively. Below 0.14 transmittance, the CRI for a particular SPD glazing was less than 80.

No strong correlation was found between CCT and CRI. The CRI of SPD glazing in a transparent state was similar to double panes glazing for SPD glazing transmittance greater than 0.24.

A Packaged Whispering Gallery Mode Strain Sensor Based On A Polymer Wire Cylindrical Micro Resonator, Vishnu Kavungal, Gerald Farrell, Qiang Wu, Arun Mallik, Yuliya Semenova

Articles

We propose a whispering gallery mode (WGM) strain sensor formed by a polymer-wire cylindrical micro resonator for strain measurement applications. WGMs are generated by evanescently coupling light into the polymer-wire resonator from a silica fiber taper fabricated by the micro heater brushing technique. Accurate and repeatable measurements of a strains up to one free spectral range (FSR) shift of the WGMs (corresponding to 0.33 % of the polymer-wire elongation, 3250 μɛ) are demonstrated experimentally with the proposed sensor. Practical packaging method for the proposed strain sensor on a glass microscope slide has also been realized making the sensor portable and …

Efficacy Of A National Hydrological Risk Communication Strategy: Domestic Wastewater Treatment Systems In The Republic Of Ireland, Paul Hynds, Owen Naughton, Eoin O'Neill, Simon Mooney

Articles

A significant body of research has focused on the role of domestic wastewater treatment systems (DWWTSs) as sources of human-specific aquatic contaminants in both developed and developing regions. However, to date few studies have sought to investigate the awareness, attitudes and behaviours of DWWTS owners and the efficacy of associated communication initiatives. The current study provides an examination of a public national engagement campaign undertaken in the Republic of Ireland which seeks to minimise the impact of DWWTSs on human and ecological health via concurrent inspection and information dissemination. Overall, 1634 respondents were surveyed using a ‘‘before and after” study …

Preface: Hydrogeology And Human Health, Paul Hynds, Mark A. Borchardt, Motomu Ibaraki

Articles

In the mid-1800s, Dr. John Snow (1813–1858), an obstetrician and anaesthesiologist, theorised that cholera, a highly infectious gastrointestinal infection associated with extremely high rates of mortality, was caused by faecal contamination of water supplies (Donaldson and Scally 2009). During the summer of 1854, a significant cholera outbreak occurred in the Soho district of London (UK), resulting in the deaths of 616 people. As part of this first modern epidemiological investigation, Dr. Snow noted that “within 250 yards of the spot where Cambridge Street joins Broad Street there were upwards of 500 fatal attacks of cholera in 10 days (…) suspected …

An In Vitro Study Of The Interaction Of The Chemotherapeutic Drug Actinomycin D With Lung Cancer Cell Lines Using Raman Micro-Spectroscopy, Zeineb Farhane, Hugh Byrne, Franck Bonnier

Articles

The applications of Raman micro-spectroscopy have been extended in recent years into the field of clinical medicine, and specifically in cancer research, as anon-invasive diagnostic method in vivo and ex vivo, and the field of pharmaceutical development as a label free predictive technique for new drug mechanisms of action in vitro. To further illustrate its potential for such applications, it is important to establish its capability to fingerprint drug mechanisms of action and different cellular reactions. In this study, cytotoxicity assays were employed to establish the toxicity profiles for 48 and 72 hrs exposure of lung cancer cell lines, A549 …

Validation Of A Membrane Touch Biosensor For The Qualitative Detection Of Igg Class Antibodies To Herpes Simplex Virus Type 2, Tony Loughman, Baljit Singh, Brian Seddon, Philip Noone, Padmanabhan Santhosh

Articles

A novel type of biosensor was assessed for application to the qualitative determination of circulating antibodies to herpes simplex virus type 2 (HSV-2). The device utilises a high activity HSV-2 type specific gG2 antigen for antibody capture and commercially available ELISA reagents. The study compares the diagnostic performance of a prototype HSV-2 biochip to well-established in vitro tests routinely applied in clinical procedures. A panel of human serum samples (n = 60) previously characterised for HSV-2 serological status using the DiaSorin LIAISON® HSV-2 chemiluminescent immunoassay were assayed on the HSV-2 biochip and the Focus Diagnostics HerpeSelect® 2 ELISA IgG kit …

The Shadow Of Free Enterprise: The Unconstitutionality Of The Securities & Exchange Commission's Administrative Law Judges, Linda D. Jellum, Moses M. Tincher

Articles

Six years ago, Congress enacted the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act), for the first time giving the Securities and Exchange Commission (SEC) the power to seek monetary penalties through its in-house adjudication. The SEC already had the power to seek such penalties in federal court. With the Dodd-Frank Act, the SEC’s enforcement division could now choose between an adjudication before an SEC Administrative Law Judge (ALJ) or a civil action before an Article III judge. With this new choice, litigants contended that the SEC realized a significant home-court advantage. For example, the Wall Street Journal …

Risk Of Regulatory Arbitrage: A Response To "Securities Regulation In Virtual Space", Wendy Gerwick Couture

Articles

In Securities Regulation in Virtual Space, Eric C. Chaffee explores the potential applicability of the securities laws to virtual transactions based on virtual activity and argues that, although many of these transactions likely qualify as “investment contracts” under S.E.C. v. W.J. Howey Co., they should be excluded under the context clause because, among other reasons, application of the securities laws would stifle creativity within this innovative space. This Response proposes a reframing of the Howey test as a response to the risk of regulatory arbitrage, argues that the context clause should only exclude transactions that do not pose such …

Supreme Court Supremacy In A Time Of Turmoil, Richard Henry Seamon

Articles

Last term's decision in James v. City of Boise encapsulates the current civil rights turmoil and the legal system's inadequate response to it. In James, the U.S. Supreme Court reversed a decision in which the Idaho Supreme Court (1) awarded attorney's fees against a civil rights plaintiff despite her credible claim of excessive police force and (2) denied that it was bound by U.S. Supreme Court decisions interpreting the federal statute authorizing the award. Although the Court in James reaffirmed the state courts' well-settled duty to obey the Court's decisions on federal law, this article shows that the duty rests …

Sharing Economy Meets The Sherman Act: Is Uber A Firm, A Cartel, Or Something In Between?, Mark Anderson

Articles

The sharing economy is a new industrial structure that is made possible by instantaneous internet communication and changes in the life, work, and purchasing habits of individual entrepreneurs and consumers. Antitrust law is an economic regulatory scheme dating back to 1890 in the United States that is designed to address centrally controlled concentrations of economic power and the threats that those concentrations pose to consumer interests and economic efficiency. In order to accommodate a modern enterprise structure in which thousands or millions of independent contractors join forces to provide a service by agreement among themselves, antitrust law requires re-envisioning and …

Walking Code, Conor Mcgarrigle

Articles

This paper describes an early stage research project that seeks to apply Situationist concepts of psychogeography to urban walking as artistic and activist practice. The project seeks to ultimately create a syntax that can be used to describe and codify the subjective spatial practice of walking in the city. This process is a conceptual and discursive exercise to generate new knowledge about urban space as embodied data space that seeks to create a practical open framework that can be deployed to algorithmically generate walking experiences tailored toward specific desires and activities.

This will be achieved through the development of algorithmic …

Study Of The Influence Of The Agarose Hydrogel Layer Thickness On Sensitivity Of The Coated Silica Microsphere, Arun Mallik, Gerald Farrell, Qiang Wu, Yuliya Semenova

Articles

In this paper, we investigate both theoretically and experimentally the influence of the agarose hydrogel layer thickness on the sensitivity of a proposed relative humidity (RH) sensor based on a silica microsphere resonator coated with agarose hydrogel. The operating principle of the sensor relies on excitation of whispering gallery modes (WGMs) in the coated silica microsphere using the evanescent field of a tapered fiber. A change in the ambient relative humidity is detected by measuring the wavelength shift of the WGMs in the transmission spectrum of the tapered fiber. Using perturbation theory, we analyze the influence of the agarose coating …

High Sensitivity Ammonia Gas Sensor Based On A Silica-Gel-Coated Microfiber Coupler, Lei Sun, Yuliya Semenova, Qiang Wu, Dejun Liu, Jinhui Yuan, Tao Ma, Xinzhu Sang, Binbin Yan, Kuiru Wang, Chongxiu Yu, Gerald Farrell

Articles

In this paper, a high-sensitivity ammonia gas sensor is proposed based on a silica-gel-coated microfiber coupler (MFC). The MFC structure is formed by the two tapered fibers with 3 μm waist diameter each, which were fabricated by using a customized microheater brushing technique. Silica gel coating was prepared by a sol-gel technique and applied on the surface of the MFC as a thin layer. The spectral characteristics of the proposed sensor were studied under various ammonia gas concentrations. The experimental results show that the coating thickness strongly affected the sensitivity of the MFC-based sensor to ammonia gas concentration. For the …

Developing A Parameterization Approach For Soil Erodibility For The Rangeland Hydrology And Erosion Model (Rhem), Osama Z. Al-Hamdan, Frederick B. Pierson, Mark A. Nearing, Christopher Jason Williams, Mariano Hernandez, Jan Boll, Sayjro K. Nouwakpo, Mark A. Weltz, Kenneth Spaeth

Articles

Soil erodibility is a key factor for estimating soil erosion using physically based models. In this study, a new parameterization approach for estimating erodibility was developed for the Rangeland Hydrology and Erosion Model (RHEM). The approach uses empirical equations that were developed by applying piecewise regression analysis to predict the differences of erodibility before and after disturbance (i.e., wildfire, prescribed fire, and tree encroachment) and across a wide range of soil textures as a function of vegetation cover and surface slope angle. The approach combines rain splash, sheet flow, and concentrated flow erodibilities into a single parameter for modeling erodibility …

Harmonizing Cultural Ip Across Borders: Fashionable Bags & Ghanaian Adinkra Symbols, J. Janewa Osei-Tutu

Articles

Global copyright and trademark laws protect symbols, names, and literary and artistic works. However, when their primary significance is cultural, because they are neither individual original works nor symbols that are used as commercial identifiers, intellectual property laws do not protect these symbols or artistic works. This is true, even if these goods are protected under national laws as part of that nation's cultural heritage. Once these cultural goods cross borders, there is no international law that will enable the country from which these goods originate to assert its rights in other countries. This Article characterizes these cultural goods as …

An Analysis Of Academic Library 3d Printing Libguides, Jennifer J. Horton

Articles

3D Printing is increasingly becoming a popular service provided by academic libraries throughout the United States. Many patrons have little or no awareness of this subject matter, so library staff have created LibGuides to promote resources. One hundred LibGuides from academic libraries were analyzed to find which types of resources and which specific titles are being promoted surrounding the subject of 3D printing. Three types of resources emerged in this study: 3D printing and 3D modeling software titles, 3D model repositories, and books related to 3D printing. This article lists and analyzes 3D printing resources.

Medical-Legal Partnerships With Communities: Legal Empowerment To Transform Care, Tamar Ezer

Articles

Medical-legal partnerships (MLPs) integrate legal services into health care settings to provide holistic care and address the social determinants of health. This article brings a legal-empowerment lens to MLP work, arguing for a stronger focus on communities. It examines the application to MLPs of bringing services to communities, investing in rights literacy, and partnering with community-based paralegals. It then outlines the potential for a transformation in health and legal services to a rights - rather than needs-based framework where communities are active partners in program design and development.

Characterization Of The Sub-Micrometer Hierarchy Levels In The Twist-Bend Nematic Phase With Nanometric Helices Via Photopolymerization: Explanation For The Sign Reversal In The Polar Response, Vitaly Panov, Sithara Sreenilayam, Yuri Panarin, Jagdish Vij, Chris Welch, Georg Mehl

Articles

Photopolymerization of a reactive mesogen mixed with a mesogenic dimer, shown to exhibit the twist-bend nematic phase (NTB), reveals the complex structure of the self-deformation patterns observed in planar cells. The polymerized reactive mesogen retains the structure formed by liquid crystalline molecules in the twist bend phase, thus enabling its observation by scanning electron microscopy (SEM). Hierarchical ordering scales ranging from tens of nanometers to micrometers are imaged in detail. Submicron features, anticipated from earlier X-ray experiments, are visualized directly. In the self-deformation stripes formed in the NTB phase, the average director field is found tilted in …

Grid Voltage Sensorless Single-Phase Half-Bridge Active Filter And Dc Bus Voltage Regulation, Samet Biricik

Articles

In this paper, a method is presented for the control of grid voltage sensorless single-phase half-bridge shunt active power filter to reduce the grid current harmonics of low-power single-phase non-linear loads. The proposed system forces the grid current to be sinusoidal without sensing and processing the grid voltage on the line. For this reason, instead of grid voltage the load current is processed by using self-tuning filter to generate reference grid current to eliminate current harmonic distortions. In order to design a low-cost system, a half-bridge voltage source converter is used to reduce driver circuits. In addition, the switching losses …

Nano-Magnetic Resonance Imaging (Nano-Mri) Gives Personalized Medicine A New Perspective, Lorenzo Rosa, Jonathan Blackledge, Albert Boretti

Articles

This paper reviews some of the major and most recent advances in nanoscale-magnetic resonance imaging (nano-MRI) for personalized medicine (PM). Nano-MRI may drastically expand the capabilities of the traditional magnetic resonance images (MRI), down to the nanometer scale and possibly, in the near future, at the atomic scale. Nano-MRI is potentially able to observe structures which cannot be seen using today’s molecular imaging, with sensitivities of many billions of times better than MRI as currently used in hospitals, for example. The paper briefly reports on the foremost research themes in nano-MRI.
