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.

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

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).

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

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

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

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.

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
