Assessment Of Nitrate And Phosphate Concentrations In Discharge Water From Ditch Networks Across Different Peatland Use Types: Implications For Sustainable Peatland Use Management, Samuel Obeng Apori, Michelle Giltrap, Julie Dunne, Furong Tian

Articles

Peat soils, when drained and transformed for different land uses, can release pollutants such as nitrate and phosphate into nearby water bodies and ecosystems through ditch networks. However, there have been limited studies to ascertain the extent and impact of these nutrient releases under various peatland use types. A total of fifty-four water samples were collected between October 2021 and January 2022 from five industrial cutaway bogs, twenty-five grasslands, and twenty-four forest plantations. The water samples were subsequently examined for nitrate–nitrogen and phosphate–phosphorus using the HACH DR890 colorimeter. This study showed that the nitrate–nitrogen concentration of the discharge water ranged …

Regulating Driving Automation Safety, Matthew Wansley

Articles

Over forty thousand people die in motor vehicle crashes in the United States each year, and over two million are injured. The careful deployment of driving automation systems could prevent many of these deaths and injuries, but only if it is accompanied by effective regulation. Conventional vehicle safety standards are inadequate because they can only test how technology performs in a controlled environment. To assess the safety of a driving automation system, regulators must observe how it performs in a range of unpredictable, real world edge cases. The National Highway Traffic Safety Administration (NHTSA) is trying to adapt by experimenting …

Antitrust Regulation Of Copyright Markets, Jacob Noti-Victor, Xiyin Tang

Articles

Late last year, a federal court sided with the Department of Justice and blocked the planned merger of book publishers Simon & Schuster and Penguin Random House. The decision was a rare collision between antitrust law and the deeply consolidated copyright content industries. Over the course of the past decade, acquisitions and mergers in the recording, music publishing, and audiovisual space have left just a handful of juggernaut content producers in their wake. Moreover, new technology companies that have entered the content-creation and distribution markets have begun to leverage their scale to further their own industry consolidation.

The Next Generation, Jeremiah Chin

Articles

What would the law look like if we let children remake it? Laws govern, classify, and circumscribe children who inherit the law and its consequences. Discourses of power invoke children as rhetorical strategies to gain political favor or obviate a position—yet children are uncritically excluded from participating in the systems that control them. Children are subjected to the laws and objects of legislation, but denied the rights, autonomy, or authority to participate in the making of law and policy. Even the conceptualization of the constitutional rights of children is treated as an assumption, ill-defined and under theorized by traditional legal …

Prevalence Of Food Insecurity Among Caregivers Of Young Children During The Covid-19 Pandemic In Ireland, Elizabeth J. O'Sullivan, Caoimhe Daly, Aileen Kennedy

Articles

Our objectives were to explore the prevalence of food insecurity in primary caregivers of young children in Ireland and to compare two tools for measuring food insecurity during the COVID-19 crisis. A cross-sectional online survey was conducted among caregivers of children aged <2 years in Ireland in May/June 2020. Relevant survey questions were closed-ended using two established tools for measuring food poverty/insecurity; the Irish Food Poverty Indicator and the Food Insecurity Experience Scale, developed by the Food and Agriculture Organization. Descriptive statistics were used to calculate the prevalence of food poverty/insecurity. To explore agreement in the classification of food insecurity by the Food Poverty Indicator and the Food Insecurity Experience Scale, Cohen's κ was used. Analyses are based on 716 participants; most had a 3rd-level education and were married or in a partnership. Per the food poverty index, Ireland's national measure of food poverty, 3.9% (n = 28) of our sample were experiencing food poverty. This rose to 10.5% (n = 75) experiencing food insecurity when using the Food Insecurity Experience Scale, which also measures worry/anxiety around access to food. There was low agreement between the tools, with 11.3% of the sample classified as food secure by one tool and food insecure by the other. Our current measure of food poverty in Ireland may not be sufficient to describe the food-access struggles or worry/anxiety about food access, experienced by the population, particularly during an emergency like COVID-19.

Optical Response Of Pdms Surface Diffraction Gratings Under Exposure To Volatile Organic Compounds, Aleksandra Hernik, Faolan Radford Mcgovern, Izabela Naydenova

Articles

Monitoring volatile organic compounds (VOCs) in indoor air is significantly gaining importance due to their adverse effects on human health. Among the diverse detection methods is optical sensing, which employs materials sensitive to the presence of gases in the environment. In this work, we investigate polydimethylsiloxane (PDMS), one of the materials utilized for gas sensing, in a novel transducer: a surface relief diffraction grating. Upon adsorption of the volatile analyte, the PDMS grating swells, and its refractive index changes; both effects lead to increased diffraction efficiency in the first diffraction order. Hence, the possibility of VOC detection emerges from the …

Comparison Of Holographic Recording Options For Reflection-Format And Transmission-Format Coupler-Type Diffractive Optical Elements: Theoretical Exploration And Experimental Validation, Dipanjan Chakraborty, Rosen Georgiev, Vincent Toal, Izabela Naydenova, Dervil Cody, Suzanne Martin

Articles

The holographic recording of gratings that have very large diffraction angles and/or slants is challenging because recording requires beam angles that are not possible without the use of prisms. However, by using a recording wavelength that is different from (usually shorter than) the intended operating wavelength, it is possible to record with less challenging beam angles. In this paper, a recently developed model that allows systematic investigation of the potential and limits of this wavelength-shift recording technique is extended to include a reflection format. Transmission and reflection recording options are compared systematically for the first time, and it is shown …

Modeling Redistribution Of Nanozeolites In Holographic Recording, Dana Mackey, Jack Lyons, Izabela Naydenova

Articles

Zeolite doped photopolymers have been studied experimentally due to their potential application in the development of optical sensors. It has been shown that dopant redistribution can be achieved by holographic recording and has a direct influence on the sensitivity of the recorded grating. To achieve better theoretical understanding of these processes, this paper proposes an extended photopolymerization-diffusion mathematical model for describing the dynamics of nanozeolite redistribution during recording in an acrylamide-based photopolymer. Using numerical simulations of this model, we investigate how recording conditions, dopant transport parameters, and initial load affect the refractive index modulation of the resulting photonic structure.

Enhancing Hybrid Photovoltaic-Thermal System Efficiency With Boron Dipyrromethene Dyes, Kenneth Coldrick, Craig Newman, John Doran, George Amarandei, Mikhail A. Filatov

Articles

A library of boron dipyrromethene (BODIPY) compounds was studied to assess their efficacy as components of a working liquid in hybrid photovoltaic-thermal (PVT) systems. Two series of BODIPY dyes were investigated: series I included alkylBODIPYs with varying substitution patterns, while series II included 1,3,5,7-tetramethyl-substituted BODIPYs featuring electron-rich aromatic groups in the meso position, such as naphthalene, anthracene, and carbazole. Series II dyes were designed to exhibit luminescence downshifting due to enhanced UV absorption (300-400 nm) and excited-state energy transfer, leading to visible-region fluorescence under UV excitation. Samples of PVT liquids based on decalin and containing each individual BODIPY dye were …

A 3 mW/cm2 …

Comparing Thin And Volume Regimes Of Analog Holograms For Wavefront Sensing, Emma Branigan, Andreas Zepp, Suzanne Martin, Matthew Sheehan, Szymon Gladysz, Kevin Murphy

Articles

Two analog holographic wavefront sensors, for measurement of defocus, have been fabricated as both thin and volume phase transmission holograms in a self-developing photopolymer. This represents the first reported direct comparison of hologram regimes when designed for wavefront sensing. An analysis of the effect of crosstalk in the presence of one other aberration mode (astigmatism X (0/90°), coma X (horizontal), and primary spherical aberration) was carried out with each version of the sensor. The performance of thin and volume analog holographic wavefront sensors was characterized under emulated conditions associated with moderate atmospheric turbulence.

Bell, Yuming Guo

Articles

Background The regional disparity of heatwave-related mortality over a long period has not been sufficiently assessed across the globe, impeding the localisation of adaptation planning and risk management towards climate change. We quantified the global mortality burden associated with heatwaves at a spatial resolution of 0.5∘×0.5∘and the temporal change from 1990 to 2019. Methods and findings We collected data on daily deaths and temperature from 750 locations of 43 countries or regions, and 5 meta-predictors in 0.5∘×0.5∘ resolution across the world. Heatwaves were defined as location-specific daily mean temperature ≥95th percentiles of year-round temperature range with duration ≥2 days. We …

Regional Variation In The Role Of Humidity On City-Level Heat-Related Mortality, Multi-Country Multi-City (Mcc) Collaborative Network, Patrick Goodman

Articles

The rising humid heat is regarded as a severe threat to human survivability, but the proper integration of humid heat into heat-health alerts is still being explored. Using state-of-the-art epidemiological and climatological datasets, we examined the association between multiple heat stress indicators (HSIs) and daily human mortality in 739 cities worldwide. Notable differences were observed in the long-term trends and timing of heat events detected by HSIs. Air temperature (Tair) predicts heat-related mortality well in cities with a robust negative Tair-relative humidity correlation (CT-RH). However, in cities with near-zero or weak positive CT-RH, HSIs considering humidity provide enhanced predictive power …
