Sustainable development of urban freight : a transition governance approach
The purpose is to examine the possibilities for a city to use insights from transition theory to affect and govern the development of the urban freight system toward environmental sustainability.
Expansion of Reducing Marine Environments During the Ireviken Biogeochemical Event : Evidence From the Altajme Core, Gotland, Sweden
New δ34Spy (pyrite) and δ34SCAS (carbonate-associated sulfate) across the Llandovery-Wenlock boundary (∼432 Ma) provide evidence for the expansion of reduced marine environments during the Ireviken Biogeochemical Event. This event consists of a major positive carbon isotope excursion, increased biotic turnover, and other major perturbations and changes within biogeochemical cycles. This interval o
Exploring Spatial Distributions of Land Use and Land Cover Change in Fire-Affected Areas of Miombo Woodlands of the Beira Corridor, Central Mozambique
Miombo woodlands (MW) are increasingly experiencing widespread land use and land cover change (LULCC). This study explores the influence of fire, agriculture, and slope variability on LULCC in the miombo of the Beira Corridor. Land use and land cover data were derived from three Landsat images for 2001, 2008, and 2018. Slope attributes were derived from the Shuttle Radar Topography Mission (SRTM).
Wigner 6 j symbols for SU(N) : Symbols with at least two quark-lines
We study a class of SU(N) Wigner 6j symbols involving two fundamental representations and derive explicit formulas for all 6j symbols in this class. Our formulas express the 6j symbols in terms of the dimensions of the involved representations, and they are thereby functions of N. We view these explicit formulas as a first step toward efficiently decomposing SU(N) color structures in terms of grou
Lifetime Surface Phosphor Thermometry - Technique Developments, Sources of Error, and Applications
Temperature is not only a fundamental aspect of everyday life, but it is also an essential metric for thermal conversion systems concerning efficiency, emissions, and component lifetime estimation. Therefore, a vast range of different methods to measure temperature has been developed. The technique of focus in this thesis is lifetime-based surface phosphor thermometry.In phosphor thermometry, one
Temperature resolved decay time components of Mg4FGeO6:Mn using the maximum entropy method
A thermographic phosphor’s decay time distribution over its temperature-sensitive range was retrieved with the Maximum Entropy Method (MEM). A decay time distribution consists of a range of decay times, each with an associated weighting for the decay time component’s prevalence in the analyzed decay curve. With the MEM, significant decay time contributions of a decay curve have high weighting and
Tools for the Advancement of Radiopharmaceutical Therapy
Radiopharmaceutical therapy is used to treat cancers and other diseases with radiolabeledpharmaceuticals. The treatment targets specific cells, and the emitted ionizing radiation cause cytotoxicdamage. Dosimetry is performed to estimate the absorbed dose from the energy deposited in the body.This requires measurement of the activity in vivo and knowledge of the retention time of the activity in tuRadiopharmaceutical therapy is used to treat cancers and other diseases with radiolabeled pharmaceuticals.

Upconversion phosphor thermometry for use in thermal barrier coatings
Measuring the temperature below the surface of a thermal barrier coating (TBC) using a thin phosphor layer is challenging primarily due to the absorption and scattering of laser excitation light and phosphor luminescence as they propagate through the coating. One way to increase phosphor luminescence could be to use upconversion phosphor thermometry, which is investigated in the current study. It
Data-driven microscopy allows for automated context-specific acquisition of high-fidelity image data
Light microscopy is a powerful single-cell technique that allows for quantitative spatial information at subcellular resolution. However, unlike flow cytometry and single-cell sequencing techniques, microscopy has issues achieving high-quality population-wide sample characterization while maintaining high resolution. Here, we present a general framework, data-driven microscopy (DDM) that uses real
PHANGS-JWST First Results : Rapid Evolution of Star Formation in the Central Molecular Gas Ring of NGC 1365
Large-scale bars can fuel galaxy centers with molecular gas, often leading to the development of dense ringlike structures where intense star formation occurs, forming a very different environment compared to galactic disks. We pair ∼0.″3 (30 pc) resolution new JWST/MIRI imaging with archival ALMA CO(2-1) mapping of the central ∼5 kpc of the nearby barred spiral galaxy NGC 1365 to investigate the
Endocannabinoid System Biomarkers in Alzheimer's Disease
Background: Alterations in the endocannabinoid system (ES) have been described in Alzheimer's disease (AD) pathophysiology. In the past years, multiple ES biomarkers have been developed, promising to advance our understanding of ES changes in AD. Discussion: ES biomarkers, including positron emission tomography with cannabinoid receptors tracers and biofluid-based endocannabinoids, are associated
Human Rights from an Islamic Perspective : A Critical Review of Arabic Peer-Reviewed Articles
The relationship between human rights and Islam is important in countries of the Arab world where religion plays a significant role in public debates and daily life. The topic is particularly relevant at a time of sharpening conflicts and polarization, when forms of government in the region, the current world order, and the legitimacy of international organizations are increasingly contested.
