description: Smart lighting systems, which evolve from traditional lighting control by utilizing feedback from user inputs and integrated sensors to manipulate the light output has been hailed as the next step in the evolution of lighting technology. Its future is bright; however, barriers to its widespread adoption include average energy saving returns that do not justify the initial investment cost, inadequate functionality and a lack of light quality control. This thesis seeks to address these problems by expanding the capabilities and enhancing the performance of smart lighting systems. To achieve this, a novel smart lighting framework featuring a tunable LED-based light engine with eight primary emitters and a custom-built LED driver, an intelligent controller, wireless connectivity complete with sensor integration via a wireless sensor module and graphical user interface was designed and developed. The inclusion of the controller and wireless sensor module allow for a highly customizable lighting system by facilitating the seamless integration of novel lighting control algorithms that are designed to enhance the system performance. In this thesis, three distinct smart algorithms were developed, implemented and tested experimentally using the smart lighting framework. Firstly, a closed-loop energy-saving algorithm was designed to enhance the energy efficiency of the lighting system. Compared to currently available energy-saving lighting systems, this control system exhibits high energy savings of up to 62% under different usage patterns, verified experimentally in continuous and discrete usage pattern environments. Moving beyond energy-savings, an open-loop chromaticity/correlated color temperature (CCT) control algorithm was realized to manipulate the produced light towards target color coordinates via an iterative optimization process. This control scheme was established to work accurately with eight primary emitters, which improves upon current chromaticity/CCT control systems that are limited to bi-color or RGB emitters. Finally, a closed-loop spectral replication algorithm was developed to allow holistic replication of target light spectra for smart lighting systems. This algorithm offers a novel approach compared to other lighting control schemes by allowing direct manipulation of the produced light SPD while also accurately maintaining other important light characteristics such as the color rendering index, CCT and chromaticity.

description: Mangrove forests store high densities of organic carbon compared to other forested ecosystems. High carbon storage coupled with high rates of deforestation means that mangroves contribute substantially to carbon emissions. Thus, mangroves are candidates for inclusion in Intended Nationally Determined Contributions (INDCs) to the UNFCC Payments for Ecosystem Services (PES) program. This study quantifies two datasets required for INDCs and PES reporting. These are annual mangrove carbon stocks from 2000 to 2012 at the global, national, and sub-national levels and global carbon emissions resulting from deforestation. Mangroves stored 4.19 Pg of carbon in 2012, with Indonesia, Brazil, Malaysia, and Papua New Guinea accounting for greater than 50% of this stock. 2.96 Pg of the global carbon stock is contained within the soil and 1.23 Pg in the living biomass. Two percent of global mangrove carbon was lost between 2000 and 2012, equivalent to a maximum potential of 316,996,250 t of CO2 emissions.

description: We use the density matrix renormalization group method to study the properties of the one-dimensional Kondo-Heisenberg model doped with Kondo holes. We find that the perturbation of the Kondo holes to the local hybridization exhibits spatial oscillation pattern and its amplitude decays exponentially with distance away from the Kondo hole sites. The hybridization oscillation is correlated with both the charge density oscillation of the conduction electrons and the oscillation in the correlation function of the Heisenberg spins. In particular, we find that the oscillation wavelength for intermediate Kondo couplings is given by the Fermi wavevector of the large Fermi surface even before it is formed. This suggests that heavy electrons responsible for the oscillation are already present in this regime and start to accumulate around the to-be-formed large Fermi surface in the Brillouin zone.

95th Annual Exhibition April 9th thru April 26th, 1984, National Association of Women Artists
Creators: name: No Name Supplied
Publisher: name: No Publisher Supplied
Year: 1984

description: The National Association of Women Artists (NAWA) was established in 1889 and is the oldest professional women's fine arts organization in the United States. NAWA's mission is to promote awareness of, and interest in, visual art created by women in the United States. As part of this effort NAWA holds an annual exhibition of works by members of the association and publishes an exhibition catalog to accompany or commemorate the annual exhibitions. These catalogs not only function as an exhibition catalog, but also as a document that summarizes the structure, membership, and activities of the association.Information that can be found in these catalogs includes lists of officers, members of the executive board and committees, prize winners, lists of exhibitor and members, and images of some of the artwork exhibited. Catalogs from the 2000s also include information on NAWA events and activities beyond the annual exhibition.Please note that the numbering of the annual catalogs was adjusted in 1960 and again in 1971. For example, NAWA designated the annual exhibition in 1960 as the 70th Anniversary Exhibition after 1959 was the 67th Annual Exhibition. These adjustments appear to have been made to reflect the date of the founding of the association, so that, by 1989, the annual exhibition commemorated the 100-year anniversary of the founding of NAWA in 1889.

description: In dieser Arbeit wurde die Frage untersucht, ob es möglich ist, mithilfe der MALDI-TOF Massenspektrometrie epidemiologische Zusammenhänge von Klebsiella pneumoniae Isolaten und deren Abstammungsbeziehungen erkennen zu können. Die analysierten Isolate (n = 56) entstammten der routinemäßigen Testung von intensivmedizinisch betreuten Patienten in einem Krankenhaus in Deutschland. Damit konzentrierte sich diese Untersuchung auf die alltägliche Epidemiologie dieser Bakterienspezies über einen Zeitraum von eineinhalb Jahren. Mittels MALDI-TOF, softwaregestützter Datenverarbeitung und Clusteranalyse konnten 12 MALDI Typen von K. pneumoniae differenziert werden. Die Betrachtung des zeitlichen Auftretens dieser Typen ließ vermuten, dass es sich hierbei um sehr begrenzte und zeitlich kurzfristige Übertragungsereignisse handelte, sog. „Mini-Cluster“. Weiterhin erfolgte eine vergleichende Analyse einer 36 Isolate umfassenden Stichprobe mit Typisierungsergebnissen einer Referenzmethode (Pulsfeldgelelektrophorese, PFGE). Mit einem Adjusted Rand Index (ARI) von 0,761 zeigte sich eine gute Übereinstimmung der beiden Typisierungsmethoden.

description: Galaxy stellar mass is known to be monotonically related to the size of the galaxy's globular cluster (GC) population for Milky Way sized and larger galaxies. However, the relation becomes ambiguous for dwarf galaxies, where there is some evidence for a downturn in GC population size at low galaxy masses. Smaller dwarfs are increasingly likely to have no GCs, and these zeros cannot be easily incorporated into linear models. We introduce the Hierarchical ERrors-in-variables Bayesian lognormAL hurdle (HERBAL) model to represent the relationship between dwarf galaxies and their GC populations, and apply it to the sample of Local Group galaxies where the luminosity range coverage is maximal. This bimodal model accurately represents the two populations of dwarf galaxies: those that have GCs and those that do not. Our model thoroughly accounts for all uncertainties, including measurement uncertainty, uncertainty in luminosity to stellar mass conversions, and intrinsic scatter. The hierarchical nature of our Bayesian model also allows us to estimate galaxy masses and individual mass-to-light ratios from luminosity data within the model. We find that 50% of galaxies are expected to host globular cluster populations at a stellar mass of $\log_{10}(M_*)=6.996$, and that the expected mass of GC populations remains linear down to the smallest galaxies. Our hierarchical model recovers an accurate estimate of the Milky Way stellar mass. Under our assumed error model, we find a non-zero intrinsic scatter of $0.59_{-0.21}^{+0.30}$ (95% credible interval) that should be accounted for in future models.

Advances in bottom up and top down fabrication of nano carbon architectures and their applications
Creators: name: Lobo, Derrek Evan
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: In this thesis three different carbon allotropes are examined through bottom up and top down approaches: carbon nanotubes (CNT), carbon nanofibers (CNF) and reduced graphene oxide (rGO). The CNTs and CNFs are synthesized by Chemical Vapour Deposition (CVD); CNTs were typically grown using a substrate of thin film of iron deposited on silicon, while CNFs were grown from a novel Ni-doped metal organic framework (MOF). Patterned and electrically conducting rGO structures are fabricated by focused ion beam induced deoxygenation on Graphene oxide (GO) films and micro-super-capacitor devices are constructed and evaluated. Arrays of aligned CNTs were integrated into fluidic micro-channels through microfabrication (photolithography and focused ion beam milling) approach. Ion-current measurements through these devices indicate currents of 0.93 nA per tube which is four orders of magnitude higher than the theoretical current through a standard pore. The CNFs are grown on a scaffold of MOF-5 in which a percentage of the Zn metal centres have been isomorphously substituted with Ni. The quality and diameter distribution of the CNFs are studied with varying percentages of Ni substitution up to 50% substitution. The CNFs are found to template the MOF microstructure, while introducing the electrically conductive CNF - an ideal situation for capacitive energy storage. The hierarchically porous CNF demonstrate a capacitance of 24 F/g and increases with increasing concentration of Ni in the parent MOF; however as Ni is still present, activation of the nickel centres in an alkaline environment leads to a pseudo capacitance of 247 F/g making it an effective electrode material. A novel top down approach for patterned reduction of graphene oxide (GO) is reported, which utilises the kinetic energy of incoming ions, specifically gallium ions, to preferentially sputter away the oxygen species due to differing volatility and bond strengths to carbon, leading to reduction. The ions are fired at the sample in the form of a focused ion beam allowing for the direct writing of conductive reduced graphene oxide region with nanometre spatial resolution. The effect of ion bombardment is also studied in detail uncovering distinct regimes of amorphisation and reduction with varying ion fluence. This is used to determine the optimal parameters for the reduction of the graphene oxide and makes use of them to directly write planar micro super capacitors into a graphene oxide film. These micro capacitors were evaluated and display a high specific capacitance (112 mF/cm2) as well as high specific energy densities (3.9 × 10-6 Wh/cm2) and ultra-high power densities (179 W/cm2), as yet unseen in this field.

description: The common observer simultaneously estimates the states of one system out of several possible systems without knowing the one being monitored. This thesis presents several developments of common observer schemes for systems with unknown inputs using multiple state observers in cascaded with logic switches. The existence conditions of the schemes are investigated in terms of the original system matrices. These conditions enable the users to know at the outset if the schemes are applicable and show that each state observer can be designed independently in which the design process is significantly simplified.

description: Quantum computers now show the promise of surpassing any possible classical machine. However, errors limit this ability and current machines do not have the ability to implement error correcting codes due to the limited number of qubits and limited control. Therefore, dynamical decoupling (DD) and encodings that limit noise with fewer qubits are more promising. For these reasons, we put forth a model of universal quantum computation that has many advantages over strategies that require a large overhead such as the standard quantum error correcting codes. First, we separate collective noise from individual noises on physical qubits and use a decoherence-free subspace (DFS) that uses just two qubits for its encoding to eliminate collective noise. Second, our bath model is very general as it uses a spin-boson type bath but without any Markovian assumption. Third, we are able to either use a steady global magnetic field or to devise a set of DD pulses that remove much of the remaining noise and commute with the logical operations on the encoded qubit. This allows removal of noise while implementing gate operations. Numerical support is given for this hybrid protection strategy which provides an efficient approach to deal with the decoherence problems in quantum computation and is experimentally viable for several current quantum computing systems. This is emphasized by a recent experiment on superconducting qubits which shows promise for increasing the number of gates that can be implemented reliably with some realistic parameter assumptions.

The Influence of Religion on Life Satisfaction in Italy
Creators: name: Ciziceno, Marco
Publisher: name: QuiEdit
Year: 2021

description: Italy is the cradle of Catholicism and, despite the secularization process, religion continues to be part of its national culture. Although Italian sociologists have investigated the religious paradigm in Italy, there are aspects of such phenomenon still little explored. This paper examines the potential influence religion has on individuals’ life satisfaction. Data from the European Value Study survey provides evidence of a two-way interaction between religion and life satisfaction, with a substantial effect only in the case of public religious forms. This association seems to be moved by the mechanism of social support, and it differs across Italian regions. Results confirm the hypothesis that in areas of Italy more exposed to social isolation religion is associated whit life satisfaction because, in those areas, religion supplies peoples’ need to belong. Further confirmation of this analysis came from the fact that in grey zones of “religious conformism” the influence of religion on life satisfaction is marginal.

description: The quantum Rabi model describes the fundamental mechanism of light-matter interaction. It consists of a two-level atom or qubit coupled to a quantized harmonic mode via a transversal interaction. In the weak coupling regime, it reduces to the well-known Jaynes-Cummings model by applying a rotating wave approximation (RWA). The RWA breaks down in the ultra-strong coupling (USC) regime, where the effective coupling strength $g$ is comparable to the energy $ω$ of the bosonic mode, and remarkable features in the system dynamics are revealed. We demonstrate an analog quantum simulation of an effective quantum Rabi model in the USC regime, achieving a relative coupling ratio of $g/ω\sim 0.6$. The quantum hardware of the simulator is a superconducting circuit embedded in a cQED setup. We observe fast and periodic quantum state collapses and revivals of the initial qubit state, being the most distinct signature of the synthesized model.

Is the Kish Household Sampling Method Better than the Birthday Method?
Creators: name: Díaz De Rada, Vidal
Publisher: name: QuiEdit
Year: 2021

description: Practically all studies on household survey sampling have given some space to the different dwelling selection processes. Since most surveys are administered to ONE person within each household, reselection is necessary within those households where there are two or more people. This study compares two within-household selection methods: the last-birthday method and the Kish method. The hypothesis is that the last-birthday method represents the population better than Kish method. It complements the “classic” representation of sex and age distribution with the representation of educational attainment, labor force participation rates, employment and unemployment by sex. The data from the European Social Survey (8th wave) shown point toward accepting this hypothesis. In spite of the last-birthday method producing a greater selection of women, the differences in educational level and labor force participation are smaller than with the Kish method.

Production of Spirulina (Arthrospira) Using Trona As A Major Ingredient of Culture Medium
Creators: name: Endrie, Muhiye
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2009

description: The impressive protein content and rapid growth of Spirulina in entirely alkaline medium have attracted the attention of both researchers and business men. Spirulina is one of the best solutions for the simple production of proteinuous food supplement. The protein content of Spirulina varies between 50 % and 70%. The present study was conducted to investigate the possibility of producing Spirulina in outdoor cultivation technology using a local product (Trona) as a substitute for the three major ingredients (NaHCO3, Na2CO3 & NaCl) in the Zarrouk's standard culture medium. The standard medium (SM) was prepared from analytical grade chemicals and used as a control. Accordingly, a modified culture medium (MM) was formulated by incorporating Trona (Na2CO3.NaHCO3.2H2O). 400 ml brine sample was taken from Lake Chitu. The sample was filtered, and the SM & MM media, were inoculated in triplicate with the Spirulia contained in the brine. The growth of Spirulina continued for ten days with every 48 h monitoring. The data on Spirulina biomass interms of yield and chlorophyll content were collected. Chemical and microbiogical analyses were done. During the growth cycle, the exponential growth phase was mathematically analyzed. In the scaling-up trial, a plastic dish with a diameter of 60 cm was used in the place of a pond for 7 days. Accordingly, biomass determination, phyico- chmical analysis and sensory evaluation were conducted. The doubling time in the analysis of the exponential growth phase gave close values for both media (SM = 53 h, MM = 51 h). The rest of the data were analyzed and means compared by t-Test using SPSS software at 5% significance level. At the end of the experiment (10th day) the mean value of biomass yield was 823.743 mg/l and 832.498 mg/l for the MM and SM respectively. Cell productivity was 83.221 mg l-1day-1 for the SM and 82.374 mg mgl-1day-1 for the MM. The crude protein content of biomass was 50.53% and to 51.93 % in the MM and SM respectively. The odour of Spirulina in SM was rated 6.333 and that of the MM was rated 5.666, while the taste of the SM was 5.888 and the MM was 5.666. Comparison of the two mean values of yield, proximate analysis and sensory analysis showed that there was no statistically significant difference between the products in the SM and MM. This justifies that Trona can be used in the culture medium to cultivate Spirulina for human consumption. Finally, Spirulina production and processing technology has been outlined. Key words: Culture medium, production, Spirulina, Trona.
Stuck under the Rainbow? Gay Parents’ Experiences with Transnational Surrogacy and Family Formation in Times of COVID-19 Lockdown
Creators: name: Monaco, Salvatore

description: Scientific progress in the medical field has contributed to the realisation of becoming parents by people who have previously been naturally excluded from procreation and parenthood, such as older, non-fertile, and homosexual persons and couples. However, depending on specific national regulations, possible pathways to becoming parents are different and often reserved only for some categories of people. This is the case, for example, in Italy, where it is more difficult for homosexual people to have a family than it is for others, since national legislation prohibits homosexuals from using any form of third-party reproduction. Consequently, many Italian same-sex couples turn to agencies abroad to realise their desire to have children, giving rise to transnational practices of family formation. The COVID-19 pandemic and severe lockdown policies have exacerbated some critical aspects of this transnational system of access to parenting. To fight the spread of coronavirus, national governments have placed limits on mobility and, consequently, also placed limits on transnational practices and trajectories of family formation. The specific aim of this paper is to provide insights into the experiences of some gay Italian fathers-to-be who have been blocked in their transnational family formation projects because of coronavirus lockdown measures. The focus lies on how these men reacted to feeling “stuck” and seeing their plans of receiving and/or bringing home their children suddenly foiled by the lockdown measures. Particular attention is paid to how these men coped with exacerbated challenges in the transnational practices of reproduction and family formation.

description: A common strategy to simulate mixed quantum-classical dynamics is by propagating classical trajectories with mapping variables, often using the Meyer-Miller-Stock-Thoss (MMST) Hamiltonian or the related spin-mapping approach. When mapping the quantum subsystem, the coupled dynamics reduce to a set of equations of motion to integrate. Several numerical algorithms have been proposed, but a thorough performance comparison appears to be lacking. Here, we compare three time-propagation algorithms for the MMST Hamiltonian: the Momentum Integral (MInt) (arXiv:1709.07474), the Split-Liouvillian (SL) (arXiv:1609.00644), and the algorithm in arXiv:1201.1042 that we refer to as the Degenerate Eigenvalue (DE) algorithm due to the approximation required during derivation. We analyse the accuracy of individual trajectories, correlation functions, energy conservation, symplecticity, Liouville's theorem and the computational cost. We find that the MInt algorithm is the only rigorously symplectic algorithm. However, comparable accuracy at a lower computational cost can be obtained with the SL algorithm. The approximation implicitly made within the DE algorithm conserves energy poorly, even for small timesteps, and thus leads to slightly different results. These results should guide future mapping-variable simulations.

Woman, Body, Conception: Unveiling the Arcana
Creators: name: Di Nicola, Paola
Publisher: name: QuiEdit
Year: 2021

description: The development of techniques of medically assisted procreation (hereinafter MAP) – above all the ability to form an embryo outside a woman’s body and surrogacy procedures – has generated heated international debate involving doctors, geneticists, biologists, psychologists, sociologists, philosophers, bioethicists, feminists, and legal experts. This long list of protagonists might yet grow as MAP affects one of the two most important symbolic aspects of human life: the beginning and the end. Reflecting on the issue of birth (the beginning of life) means asking questions about sexuality and conception which relate directly to the female body. This article highlights the decisive impact of MAP techniques on the new social imaginaries of the body, sexuality, and conception. The new symbols and myths which emerge tell of sexless, de-eroticised, and empty male and female bodies: the horizon of the imaginary now features the ‘androgynous’ woman and the ‘gynandrous’ man, while conception occurs in a relational vacuum.

description: Under certain conditions, two samples of fluid at different initial temperatures present a counterintuitive behavior known as the Mpemba effect: it is the hotter system that cools sooner. Here, we show that the Mpemba effect is present in granular fluids, both in uniformly heated and in freely cooling systems. In both cases, the system remains homogeneous, and no phase transition is present. Analytical quantitative predictions are given for how differently the system must be initially prepared to observe the Mpemba effect, the theoretical predictions being confirmed by both molecular dynamics and Monte Carlo simulations. Possible implications of our analysis for other systems are also discussed.

description: Creating a practice environment that completely engages nurses in their practice is a major concern in the nursing profession (Sayed et al., 2019). Improving practice environment has become a worldwide issue since there is still nursing shortage around the globe (Almuhsen et al., 2017).Thie purpose of this study is to determine the relationship of Practice Environment and Work Engagement of Staff Nurses in a Specialized Hospital in the Kingdom of Saudi Arabia.This study utilized a quantitative, non-experimental, descriptive correlational research design. Practice Environment Scale of the Nursing Work Index (PES NWI) (Lake, 2002) and Utrecht Work Engagement Scale (UWES) (Schaufeli & Bakker, 2004) were used in this study to measure practice environment and work engagement of staff nurses in a Specialized Hospital in the Kingdom of Saudi Arabia.This study showed that staff nurses have high perception on their practice environment (3.93 ±SD .507) and average level of work engagement (4.2 ± .910). In addition, it proved a positive significant correlation between Practice Environment and Work Engagement of Staff Nurses in a Specialized Hospital in the Kingdom of Saudi Arabia. Furthermore, there is a positive significant correlation between Work Engagement and Demographic Characteristics in terms of age, educational attainment, and years in current unit.Nurse administrators, managers and leaders hold a vital role in practice environment and work engagement in reviewing practices, policies, and procedures.Keywords: work environment, work conditions, practice environment, work engagement, work environment and work engagement, practice environment and work engagement.

description: We developed a resistance measurement using radio frequency reflection to investigate the electrical transport characteristics under destructive pulsed magnetic fields above 100 T. A homemade flexible printed circuit for a sample stage reduced the noise caused by the induced voltage from the pulsed magnetic fields, improving the accuracy of the measurements of the reflected waves. From the obtained reflectance data, the absolute value of the magnetoresistance was successfully determined by using a phase analysis with admittance charts. These developments enable more accurate and comprehensive measurements of electrical resistance in pulsed magnetic fields.

description: We systematically study the master space of brane brick models that represent a large class of 2d (0,2) quiver gauge theories. These 2d (0,2) theories are worldvolume theories of D1-branes that probe singular toric Calabi-Yau 4-folds. The master space is the freely generated space of chiral fields subject to the J- and E-terms and the non-abelian part of the gauge symmetry. We investigate several properties of the master space for abelian brane brick models with U(1) gauge groups. For example, we calculate the Hilbert series, which allows us by using the plethystic programme to identify the generators and defining relations of the master space. By studying several explicit examples, we also show that the Hilbert series of the master space can be expressed in terms of characters of irreducible representations of the full global symmetry of the master space.

description: Die Immun-Checkpoint-Inhibition blockiert die ko-inhibitorische Interaktion zwischen Lymphozyten und Tumorzellen in der Tumormikroumgebung und stellt eine essentielle Therapieoption für metastasierte Krebserkrankungen, einschließlich Nierentumoren dar. Es können dabei spezifische Antikörper-basierte Medikamente verabreicht werden, die insbesondere gegen den programmierten-Todes-Rezeptor (PD-1) oder seinen Liganden (PD-L1) gerichtet sind. Aufgrund des heterogenen Ansprechens der Therapie, ist die Ana- lyse von PD-L1 und PD-1 in der Tumormikroumgebung sowie von löslichen Formen wie sPD-L1 und sPD-1 im Blut zur Identifizierung von prognostischen und prädiktiven Bio- marker-Surrogaten von Interesse.
In dieser Arbeit erfolgten die Nachweise von PD-L1 und PD-1 auf mRNA- und Protein- ebene im Tumorgewebe mit Differenzierung von Tumor- und Immunzellen. Zudem wur- den die löslichen Formen (sPD-L1) und (sPD-1) im Blut betrachtet. Dabei konnten Tu- morzellen als primäre Expressionsquelle von PD-L1 identifiziert werden, während Im- munzellen überwiegend PD-1 exprimierten. Diese Beobachtung basiert auf der Korrela- tion zwischen PD-L1-mRNA und PD-L1 Proteinexpression, repräsentiert durch den An- teil der gefärbten Tumorzellen (TPS-Score), sowie der Korrelation zwischen PD-1- mRNA und der Proteinexpression in Immunzellen (IC-Score). In Ergänzung, wurde be- obachtet, dass die Infiltration der untersuchten Immunzellen in die Tumorkompartimente mit erhöhten Spiegeln von PD-L1 und eines Interferon-g Markers (CXCL10) einherging, was die Interferon-g abhängige Signaltransduktion zwischen Immun- und Tumorzellen reflektiert. Bemerkenswert ist ferner, dass der PD-L1-TPS-Score und die PD-L1-mRNA Konzentration im Tumorgewebe nicht mit den sPD-L1-Spiegeln im Blut korrelierten. Vielmehr deuten ein signifikanter Anstieg der sPD-L1-Werte im Blutserum nach Tumor- resektion sowie eine Korrelation zwischen sPD-L1 und PD-L1-mRNA im Blut darauf hin, dass nicht primär das Tumorgewebe, sondern periphere Blutzellen zu den sPD-L1 Werten im Blut beitragen.
Die Ergebnisse zeigen, dass die Interaktion zwischen Tumor- und Immunzellen sowie beteiligter Signalmoleküle wie Interferon-g relevant für die Expression von PD-L1 bei Nierentumoren sind, wobei Unterschiede zwischen den verschiedenen Tumorentitäten bestanden. Eine Assoziation zwischen PD-L1 im Tumor zur löslichen Form sPD-L1 im peripheren Blut war nicht offenkundig.

description: In conjunction with sustainability and waste minimization concept, biohydrogen emerges as an alternative energy carrier to replace fossil fuels. This thesis investigates the potential reuse of combined palm oil, pulp and paper mill effluent as a substrate to produce biohydrogen and to reduce the organic pollutants simultaneously, via photofermentation by Rhodobacter sphaeroides. Further study examines the potential improvement of biohydrogen production through the application of ultrasound technology in three stages: (i) onto combined-effluents substrate before photofermentation, (ii) onto liquid inoculum before photofermentation, and (iii) intermittent ultrasonication during photofermentation.

description: We study the nonequilibrium steady state of the driven-dissipative Bose-Hubbard model with Kerr nonlinearity. Employing a mean-field decoupling for the intercavity hopping $J$, we find that the steep crossover between low and high photon-density states inherited from the single cavity transforms into a gas$-$liquid bistability at large cavity-coupling $J$. We formulate a van der Waals like gas$-$liquid phenomenology for this nonequilibrium situation and determine the relevant phase diagrams, including a new type of diagram where a lobe-shaped boundary separates smooth crossovers from sharp, hysteretic transitions. Calculating quantum trajectories for a one-dimensional system, we provide insights into the microscopic origin of the bistability.
