Selection of Maintenance Strategy for Light Rail Transit by Using AHP Algorithm
Creators: name: Muluken, Assefa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Maintenance has infinite number of functions and its strategic formulation needs infinite number of factors. This kind of multi criteria problems should be handled by multi criteria decision making process. Therefore, the main objective of this research is identifying key maintenance factors and then model maintenance strategy with AHP to select the possible priorities of maintenance strategy by using expert decision method. Selection of efficient maintenance strategy can be achieved by pairwise comparison of the identified functions. This qualitative survey assessed the opinion of maintenance professionals (11 personals) and rolling stock manufacturing & design experts (7 personals) at METEC locomotive division to select the maintenance system. The research method comprises identification of maintenance factors and suggestion of possible maintenance strategies. AHP analysis shows that safety (38.2%) become the highest priority of LRT system. value added (20%), implementation cost (13.2%), support system integration (11.5%), and implementation capability (8.2%), performance measurement (5%) and stock & material management (3.9%) are the succeeding priority factors on implementing maintenance system. The analysis discovered that total productive maintenance is the most suitable strategy to be implemented for LRT system and corrective maintenance is the least to follow. Sensetivity and sanity is checked for the input data to the software. Introducatory step for implementation of TPM is proposed for LRT system . Finally the bigest contribution of this thesis is an application of the AHP algorithm, which is one of multi criterea decission method for selection of maintenance strategy instead of traditional way of selecting " based on experience method" in Ethiopian industries.

The origin of single low-mass WDs: another problem that consequential angular momentum loss in CVs might solve
Creators: name: Zorotovic, Monica

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Low-mass helium-core white-dwarfs (WDs) with masses below 0.5 Msun are known to be formed in binary star systems but unexpectedly a significant fraction of them seem to be single. On the other hand, in Cataclysmic Variables (CVs) a large number of low-mass WD primary stars is predicted but not observed. We recently showed that the latter problem can be solved if consequential angular momentum loss causes especially CVs with low-mass WDs to merge and form single stars. Here we simulate the population of single WDs resulting from single star evolution and from binary star mergers taking into account these new merging CVs. We show that according to the revised model of CV evolution, merging CVs might be the dominant channel leading to the formation of low-mass single WDs and that the predicted relative numbers are consistent with observations. This can be interpreted as further evidence for the revised model of CV evolution we recently suggested. This model includes consequential angular momentum loss that increases with decreasing WD mass and might not only explain the absence of low-mass WD primaries in CVs but also the existence of single low-mass WDs.

description: A model linking the molecular-scale dynamics of fluids confined to nano-pores to nuclear magnetic resonance (NMR) relaxation rates is proposed. The model is fit to experimental NMR dispersions for water and oil in an oil shale assuming that each fluid is characterised by three time constants and Lévy statistics. Results yield meaningful and consistent intra-pore dynamical time constants, insight into diffusion mechanisms and pore morphology. The model is applicable to a wide range of porous systems and advances NMR dispersion as a powerful tool for measuring nano-porous fluid properties.

Such Stuff as PD is Made On: A Case Study of a Professional Development Cohort
Creators: name: Lesus, Melina
Publisher: name: University of Illinois at Chicago
Year: 2023

description: In this qualitative case study, I examined how teacher instructional practices and beliefs around teaching literature were impacted after self-selecting into a sustained professional development opportunity called Bard Core. Specifically, I ask, 1. What are the perspectives of secondary ELA teachers as to how a self-selected, year-long, theater-based professional development impacted their professional learning, curriculum development, and/or instructional practice? And 2. How do the learning and experiences of the Bard Core program carry over into participants’ instructional practices and beliefs around teaching literature in general and teaching canonical literature specifically? Using Communities of Practice (Lave & Wenger, 1991) and the Historically responsive Literature Framework (Muhammad, 2020) as data analysis frameworks, I examined the experiences of the 18th cohort of Bard Core. After systematically analyzing the data, I found that the participants felt that they gained professional learning that they considered valuable and that Bard Core equipped participants with tools for curriculum development that they did not previously possess and facilitated a shift in thinking in terms of what was appropriate in their curriculum. Similarly, participants experimented with instructional practices and classroom activities they would not have tried or thought appropriate before Bard Core. Some of the Bard Core content, though, was universally adopted by all teachers, while some of it was universally ignored. In doing this work, the teachers who participated in Bard Core formed a Community of Practice (Lave & Wenger, 1991; Wenger, 1998) where they were able to be vulnerable and leverage one another’s expertise in addition to the new content they were learning together. The implications of this study yielded important findings relevant to teachers and teacher educators who are interested in how to make literature instruction more culturally relevant, culturally sustaining, and historically responsive.

description: With the energy sector being one of the largest sources of global greenhouse-gas emissions, a swift change in the ways of energy generation and consumption is needed for a fulfilment of climate goals. But while the existence of global warming and the resulting need for action are widely agreed upon, there is a lot of discussion around the concrete measures and their timeline. A major cause of this discussion is that of uncertainty, both with regard to possible outcomes, as well as to a multitude of factors such as future technology innovation (concerning both availability and costs), and final energy demands, but also socio-economic factors such as employment or sufficiency. This paper aims to give valuable insights into this uncertainty by applying the method of exploratory sensitivity analysis to an application of the Global Energy System Model (GENeSYS-MOD) for the German energy system. By computing over 1500 sensitivities across 11 core parameters, the key influential factors for the German Energiewende can be quantified, and possible chances, such as so-called no-regret options, as well as potentials barriers (if assumptions are not met) can be distilled. Results show that final energy demand developments, renewable potentials and costs, as well as carbon pricing are among the main drivers of the analyzed energy pathways. It would thus be highly beneficial for policy makers to focus on these key issues to ensure a timely transformation of the energy system and reach set climate targets.
Railway Timetable Stability Analysis: Case of Addis Ababa LRT
Creators: name: Asfaw, Workineh
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Recently, railway traffic has increased considerably in the different parts of the world; moreover, it is expected that railway transportation will further grow for both passenger and freight transportation. These developments create needs to optimize both the utilization of the existing infrastructure and the coordination tasks inside the railway company. Specially, the process times at stations should be well monitored to deliver efficient services. Railway timetable is affected by several factors. The fact that makes the case more serious is that a disturbance encountered one train may propagate to the whole network unless a timetable that absorbs the fluctuation has been designed. This makes the railway timetable to be the heart of railway operation. Hence, the thesis at hand is aimed to develop stability analysis method which is used to design more stable timetable to handle the disturbances occurring to the railway network. In this research, both the interior and exterior factors that affect railway timetable stability were taken into account. In view of that, at the end of the research work, a model that is used to analyze trains timetable stability has been developed. The developed model is applicable to passengers' railway network like Addis Ababa LRT.

description: The organic-inorganic hybrid lead trihalide perovskites have been emerging as the most attractive photovoltaic material. As regulated by Shockley-Queisser theory, a formidable materials science challenge for the next level improvement requires further band gap narrowing for broader absorption in solar spectrum, while retaining or even synergistically prolonging the carrier lifetime, a critical factor responsible for attaining the near-band gap photovoltage. Herein, by applying controllable hydrostatic pressure we have achieved unprecedented simultaneous enhancement in both band gap narrowing and carrier lifetime prolongation (up to 70~100% increase) under mild pressures at ~0.3 GPa. The pressure-induced modulation on pure hybrid perovskites without introducing any adverse chemical or thermal effect clearly demonstrates the importance of band edges on the photon-electron interaction and maps a pioneering route towards a further boost in their photovoltaic performance.

Development of An Effective Inspection and Maintenance Strategy based on Rolling Contact Surface Crack Propagation Analysis
Creators: name: Iyoel, Chuchu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The issue of railway rail damage can"t be seen easily and it requires attention and researching because most railway accidents are caused by the wheel/rail damage. The aim of this paper is to develop an effective inspection and maintenance strategy based on rolling contact surfaces crack propagation analyse. This will help to prevent the occurrence of rail failure by taking the required action at the right time, and extend the rail life expectancy, reduce the rail maintenance work and its cost. The frequency of rail inspection tends to vary from one railroad to another, yet it is usually based on either time or traffic tonnage. Railroad companies have evolved their rail inspection schedules empirically based on long field experience. Rail defect management refers to the development and implementation of strategies to control the risk of rail failure. The primary method to control the risk is a rail inspection through non-destructive evaluation and, is a replacement of rails based on the remedial action plan. This work has undertaken the study of fatigue cracks in rails using Finite element method (FEM) modelling and analytical solutions to provide rail inspectors for the quick assessment of the severity of surface breaking and embedded cracks in rails. The work does investigate crack propagation phenomena on the heads of rails. Based on the analysis results, the mechanism for remedial action is developed based on critical crack size at rail head, to help infrastructure manager"s decision. Then, effective number of rail inspection frequency is determined as three times a year to prevent the occurrence of rail failure by taking the required action at the right time, and extend the rail life expectancy, reduce the rail maintenance work and its cost. Finally, appropriate rail inspection and maintenance strategy model (flowchart) is adopted for Ethiopian railway industry.

description: Communities of microbial organisms and their metabolic capabilities are vital for human health, agriculture, and ecology. However, studying naturally occurring microbial communities is challenging due to the complex interactions among the species involved. Genome-scale metabolic modeling is a promising approach for their study, but applying it to communities requires more attention than for single organisms. Therefore, we developed an automated workflow that integrates multiple genome-scale metabolic models into a community and computes the community's elementary conversion modes, which describe the full range of feasible metabolic behaviors in the community. To demonstrate the feasibility of our approach, we applied it to a biogas-producing microbial community and characterized the full range of feasible metabolic behaviors. Our results show that the sum of pairwise interactions between the members of the community can explain 96% of the feasible community behavior. Our approach provides a powerful tool for understanding the metabolic potential of microbial communities, which is essential for various applications in health, agriculture, and ecology.

Nitric Oxide is an Epitranscriptomic Regulator of Gene Expression by Inhibiting m6A mRNA Demethylation.
Creators: name: Kuschman, Hannah P
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Elevated nitric oxide (NO) is a well-established negative prognostic indicator across multiple cancer types. The aim of this project was to elucidate novel signaling mechanisms by which NO drives aggressive cancer development. N6-methyladenosine (m6A) is the most abundant and conserved internal transcriptional modification in mRNA. m6A plays an essential role in biological function; however, disruption of m6A levels promote aberrant cell behaviors, especially tumorigenesis. Therefore, we sought to expand our understanding of NO as an epigenetic regulator via mediating m6A mRNA methylation and ultimately leading to regulation of oncogenic transcripts in triple negative breast cancer. We discovered a novel mechanism by which NO inhibits m6A demethylases, iron- and alpha-ketoglutarate-dependent dioxygenases FTO and ALKBH5. Inhibition of demethylation by NO markedly increased cellular m6A mRNA levels. Next, we examined the role of NO in regulating gene expression downstream of m6A mRNA methylation changes. By combining RNA sequencing and m6A methylated RNA immunoprecipitation sequencing, we identified genes that were differentially expressed in response to NO-mediated hypermethylation of m6A mRNA, many of which are associated with tumorigenic hallmarks. Taken together, these data have revealed a novel signaling mechanism such that NO acts an epitranscriptomic regulator of m6A mRNA methylation and thus a driver of oncogenic gene expression.

description: Multiple sclerosis (MS) is a chronic, inflammatory, demyelinating disease of the central nervous system. Research on MS has focused on anti-inflammation and anti-demyelination. Ursolic acid (UA) reduces nervous system inflammation and has a therapeutic effect on experimental autoimmune encephalomyelitis (EAE), an animal model of MS. However, its anti-inflammatory mechanism in treating MS has not yet been fully elucidated. In this study, we used network pharmacology to analyses the likely mechanisms of UA in MS treatment and verified the results using molecular docking and an in vivo experiment. Network pharmacology identified 52 related targets of UA for MS, and UA potentially treated MS through the TNF-α/NF-κB signaling pathway. Molecular docking revealed that JNK, p65, IκBα, TNF-α, and IL-6 had strong affinities for UA. In the in vivo experiment, mice were randomly assigned to a control group, an EAE group, and a UA group (50 mg/kg/d). The results indicated that UA treatment improved weight loss and nerve damage in EAE mice, decreased the serum levels of IFN-γ, TNF-α, and IL-6, and reduced spinal cord inflammation and demyelination of EAE. Western blotting analysis of the spinal cord also indicated that the levels of p-p65/p65, p-JNK/JNK, and p-IκBα were significantly upregulated in the EAE group compared with the control group, whereas the UA treatment could reverse the results. In summary, UA reduces inflammation in EAE by inhibiting the activation of the TNF-α/NF-κB signaling pathway and downregulating the expression of the proinflammatory cytokines IFN-γ, TNF-α, and IL-6.

description: The $\mathrm{^{16}O}(α, α^{\prime})$ reaction was studied at $θ_{lab} = 0^\circ$ at an incident energy of $\textrm{E}_{lab}$ = 200 MeV using the K600 magnetic spectrometer at iThemba LABS. Proton and $α$-decay from the natural parity states were observed in a large-acceptance silicon-strip detector array at backward angles. The coincident charged particle measurements were used to characterize the decay channels of the $0_{6}^{+}$ state in $\mathrm{^{16}O}$ located at $E_{x} = 15.097(5)$ MeV. This state is identified by several theoretical cluster calculations to be a good candidate for the 4-$α$ cluster state. The results of this work suggest the presence of a previously unidentified resonance at $E_{x}\approx15$ MeV that does not exhibit a $0^{+}$ character. This unresolved resonance may have contaminated previous observations of the $0_{6}^{+}$ state.

description: Abstract Objective: With this scoping review, we aim to identify existing (clinical) pharmacist interventions for patients with chronic non-cancer pain (CNCP). Introduction: CNCP is a highly prevalent burden associated with a number of comorbidities. Therefore, CNCP is complex and difficult to handle. Gold standard for the treatment of CNCP is a multi-modal approach, including interprofessional health care providers like medical doctors, physiotherapists, nurses and pharmacists. The scope and content of existing pharmacist interventions in CNCP is, however, unclear. Methods: We will follow the PRISMA extension for scoping reviews. The search strategy will composed of the two thematic blocks ‘Pharmacists’ and ‘Chronic Non-Cancer Pain’. We will search Medline, Embase and PsycInfo via Ovid, CINAHL via EBSCO and the Cochrane Library. Both title and abstract screening and full-text screening will be performed by two independent reviewers. Data extraction will be performed by one reviewer and validated by a second. The screening and extraction process will take place in April and May 2023. Ethics and dissemination: No ethics approval was sought as only publicly available literature will be searched. The review will be disseminated in a peer-reviewed journal and presented at congresses.

description: We study the effects of the non-attractor initial conditions for the canonical single-field inflation. The non-attractor stage can last only several $e$-folding numbers, and should be followed by hilltop inflation. This two-stage evolution leads to large scale suppression in the primordial power spectrum, which is favored by recent observations. Moreover we give a detailed calculation of primordial non-Guassianity due to the "from non-attractor to slow-roll" transition, and find step features in the local and equilateral shapes. We conclude that a plateau-like inflaton potential with an initial non-attractor phase yields interesting features in both power spectrum and bispectrum.

description: The $^{181}$Ta quadrupole resonance (NQR) technique has been utilized to investigate the microscopic magnetic properties of the Weyl semi-metal TaP. We found three zero-field NQR signals associated with the transition between the quadrupole split levels for Ta with $I$=7/2 nuclear spin. A quadrupole coupling constant, $ν_{\mathrm{Q}}$ =19.250 MHz, and an asymmetric parameter of the electric field gradient, $η$ = 0.423 were extracted, in good agreement with band structure calculations. In order to examine the magnetic excitations, the temperature dependence of the spin lattice relaxation rate (1/$T_{\mathrm{1}}T$) has been measured for the $f_{\mathrm{2}}$-line ($\pm$5/2 $\leftrightarrow$ $\pm$3/2 transition). We found that there exists two regimes with quite different relaxation processes. Above $T\text{*}$ $\approx$ 30 K, a pronounced (1/$T_{\mathrm{1}}T$) $\propto$ $T^{2}$ behavior was found, which is attributed to the magnetic excitations at the Weyl nodes with temperature dependent orbital hyperfine coupling. Below $T\text{*}$, the relaxation is mainly governed by Korringa process with 1/$T_{\mathrm{1}}T$ = constant, accompanied by an additional $T^{-1/2}$ type dependence to fit our experimental data. We show that Ta-NQR is a novel probe for the bulk Weyl fermions and their excitations.

description: Quantum mechanics allows for multiple predictions for the outcome of an EPR experiment. The correct calculation must be used, guided by the physical conditions of the experiment. The quantum joint prediction for EPR correlation is derived and shown to involve a single sampling. The solution for separated measurement, where there are two private samplings, is then developed using orthodox quantum mechanics with Luders' rule for state projection on measurement. The separated solution is shown to duplicate the predictions of the quantum joint solution. However, it is shown that this solution requires superluminal transmission of information and therefore it is physically impossible. Alternative predictions respecting special relativity are developed using both Von Neumann projection and null projection (no projection at all). Conditions for the proper application of state projection rules are considered and Luders' rule is identified as the primary culprit in the EPR paradox. It cannot be applied to EPR.

Effect of Track Stiffness Variation on the Dynamic Response of Passenger Vehicle
Creators: name: Theodros, Yohannes
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: This paper investigates the effect of track stiffness variation on the dynamic behavior of a railway passenger vehicle. For the analysis, MBS model of the vehicle and the track was developed using SIMPACK software. Two models are developed, one with constant track stiffness and the other with variable track stiffness. The simulation was done on a straight track with no irregularity of rails and wheels. Track stiffness variation may have different causes, however in this research track stiffness variation caused by sleeper spacing was considered. The dynamic characteristic of railway vehicle greatly depends on the motion of the vehicle. To consider this, the models are allowed to move in three different velocity profiles i.e. the motion of the vehicle during service braking, emergency braking and taking greater acceleration and deceleration values. For all velocity profiles the outputs of the simulations showed, the vertical and lateral accelerations and displacements of the car body are greater during variable track stiffness case. However, the simulation results for the bogie frame showed an increase in some cases and decrease in the other. From these outputs we can conclude that, track stiffness variation increases the vertical as well as the lateral displacement and acceleration of the car body and it may not have effect on the bogie frame.

The Effects of Place-Based Policy: Evidence from Tax Increment Financing
Creators: name: Kim, Geon
Publisher: name: University of Illinois at Chicago
Year: 2023

description: This dissertation examines the effects of tax increment financing (TIF) in Cook County, Illinois as an example of place-based policy (PBP). Its aim is to provide new perspectives and call attention to un(der)explored dimensions in assessing not only TIF but more broadly all types of PBPs. Qualitative case studies and two statistical analyses make up this three-part study and they together illuminate the effects of TIF and its underlying mechanisms. Specifically, I first conduct case studies to demonstrate detailed economic and institutional mechanisms in which TIF districts operate. Second, I measure the dynamic, spillover, and persistent effects of TIF. And, lastly, I examine the distributional implications of TIF and how TIF has performed in reducing spatial inequality in the region. The main takeaways from the analyses are as follows: 1) The effects of TIF appear to be heterogeneous by time and region (i.e., Chicago and non-Chicago municipalities in Cook County); TIF designation is negatively correlated with the number of establishments in Chicago, particularly around 10 years after TIF districts are established, while I find evidence of the positive effects in the non-Chicago municipalities on employment. This may be due to differences in taxing and fiscal structures, less competition, and cannibalization (i.e., poaching businesses from other TIFs). 2) I find evidence of persistent and sustaining effects of TIF after its termination. The presence of the persistent effects indicates that TIF districts may successfully establish positive externalities and that transforming a locality from low-density economic activity to high-density economic activity through PBP(s) could jumpstart a new agglomeration economy. 3) TIF has beneficial effects on the income and well-being of residents, but these positive effects are not substantial enough to catch up with other relatively affluent areas and reduce spatial inequality in the region.

description: [Methods]. We obtained high-precision radial velocities with HARPS on the ESO 3.6 m telescope and determined precise stellar elemental abundances (~0.01 dex) using MIKE spectra on the Magellan 6.5m telescope. [Results]. Our data indicate the presence of a planet with a minimum mass of 26 Earth masses around the solar twin HIP 68468. The planet is a super-Neptune, but unlike the distant Neptune in our solar system (30 AU), HIP 68468c is close-in, with a semi-major axis of 0.66 AU, similar to that of Venus. The data also suggest the presence of a super-Earth with a minimum mass of 2.9 Earth masses at 0.03 AU; if the planet is confirmed, it will be the fifth least massive radial velocity planet discovery to date and the first super-Earth around a solar twin. Both isochrones (5.9 Gyr) and the abundance ratio [Y/Mg] (6.4 Gyr) indicate an age of about 6 billion years. The star is enhanced in refractory elements when compared to the Sun, and the refractory enrichment is even stronger after corrections for Galactic chemical evolution. We determined a NLTE Li abundance of 1.52 dex, which is four times higher than what would be expected for the age of HIP 68468. The older age is also supported by the low log(R'HK) (-5.05) and low jitter. Engulfment of a rocky planet of 6 Earth masses can explain the enhancement in both lithium and the refractory elements. [Conclusions]. The super-Neptune planet candidate is too massive for in situ formation, and therefore its current location is most likely the result of planet migration that could also have driven other planets towards its host star, enhancing thus the abundance of lithium and refractory elements in HIP 68468. The intriguing evidence of planet accretion warrants further observations to verify the existence of the planets that are indicated by our data and to better constrain the nature of the planetary system around this unique star.

description: A method for obtaining a smooth, single crystal diamond surface is presented, whereby a sacrificial defective layer is created by implantation and graphitized by annealing before being selectively etched. We have used O+ at 240 keV, the main process variables being the ion fluence (ranging from 3x10^15 cm^-2 to 3x10^17 cm^-2) and the final etching process (wet etch, H2 plasma and annealing in air). The substrates were characterized by atomic force microscopy, optical profilometry and white beam X-ray topography. The influence of the various process parameters on the resulting lift-off efficiency and final surface roughness is discussed. An O+ fluence of 2x10^17 cm^-2 was found to result in sub-nanometre roughness over tens of um^2.

description: The frequency of Galactic stellar encounters the Solar system experienced depends on the local density and velocity dispersion along the orbit of the Sun in the Milky Way galaxy. We aim at determining the effect of the radial migration of the solar orbit on the rate of stellar encounters. As a first step we integrate the orbit of the Sun backwards in time in an analytical potential of the Milky Way. We use the present-day phase-space coordinates of the Sun, according to the measured uncertainties. The resulting orbits are inserted in an N-body simulation of the Galaxy, where the stellar velocity dispersion is calculated at each position along the orbit of the Sun. We compute the rate of Galactic stellar encounters by employing three different solar orbits ---migrating from the inner disk, without any substantial migration, and migrating from the outer disk. We find that the rate for encounters within $4\times10^5$ AU from the Sun is approximately 21, 39 and 63 Myr$^{-1}$, respectively. The stronger encounters establish the outer limit of the so-called parking zone, which is the region in the plane of the orbital eccentricities and semi-major axes where the planetesimals of the Solar system have been perturbed only by interactions with stars belonging to the Sun's birth cluster. We estimate the outer edge of the parking zone at semi-major axes of 250--1300 AU (the outward and inward migrating orbits reaching the smallest and largest values, respectively), which is one order of magnitude smaller than the determination made by Portegies Zwart & Jílková (2015). We further discuss the effect of stellar encounters on the stability of the hypothetical Planet 9.

description: Studies that have been carried out on men that pay for sexual services often haphazardly (re)create client typologies perceiving the identity of men that pay for sexual services ? often condescendingly described as ?the John? ? as a fixed, trans-historical and trans-national entity. Instead of asking ?why? men pay for sexual services this doctoral dissertation addresses ?how? men pay for sexual services. Drawing on 44 interviews, evenly distributed on heterosexual Swedish and Dutch (upper)middle class white men, supplemented by online questionnaires and material of specific forums, the ?how? is addressed with reference to the men?s own narratives and reflexive accounts. In this doctoral dissertation it will be claimed that from the position and perspectives of these clients/consumers/customers of sexual services, Sweden and the Netherlands cannot be perceived as having oppositional policy regimes. Far beyond calculations of a reduction or increase of ?prostitution? when ?prostitution? is partially criminalized or regulated, I will uncover and unravel the complex processes of becoming a client by the multitude of strategies that Swedish and Dutch men employ in their home country and abroad. Furthermore, by describing the technical as well as spatial displacements I will claim that national discourses work as power techniques that govern the modes of thought of both Swedish and Dutch men that pay for sexual services in their own country and abroad.

description: Fuel injection has a critical role in an internal combustion engine and a significant effect on the quality of the fuel spray. In turn, fuel spray directly affects an engine´s combustion, efficiency, power and emissions. This study evaluated three different injector nozzles in a highspeed, non-road diesel engine. It was run on diesel fuel oil (DFO) and testing was conducted at three different engine loads (100%, 75% and 50%) and at two engine speeds (2,200 rpm and 1,500 rpm). The nozzles had 6, 8 and 10 holes and a relatively high mass flow rate (HF). The study investigated and compared injection and combustion characteristics, together with gaseous emissions. The combustion parameters seemed to be very similar with all studied injector nozzles. The emission measurements indicated general reductions in hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) at most load/speed points when using the 6- and 10-hole nozzles instead of the reference 8-hole nozzles. However, smoke number increased when the alternative nozzles were used.

description: V-QCD is a class of effective holographic models for QCD which fully includes the backreaction of quarks to gluon dynamics. The physics of the theta-angle and the axial anomaly can be consistently included in these models. We analyze their phase diagrams over ranges of values of the quark mass, N_f/N_c, and theta, computing observables such as the topological susceptibility and the meson masses. At small quark mass, where effective chiral Lagrangians are reliable, they agree with the predictions of V-QCD.

description: The field of Meta-Reinforcement Learning has gained a lot of traction in recent years, especially in the overarching research concerning control and decision making. However, real life applications of these methodologies are far and few in between.. In our work we seek to expand as well as have a fresh take at the dynamic treatment regime problems and the existing deep meta-RL solutions to it. We attempt to do so by incorporating the very promising Transformer-encoder architecture that has practically revolutionized speech and image processing. We propose a new architecture that effectively exploits the self-attention mechanism present as a contextualization framework that acts as a memory component for the meta-algorithm. We host a policy gradient methodology above this meta-framework that solves sequential decision problem for treating Head and Neck Cancer patients.

description: Introduction: To evaluate the safety and overall improvement by the use of prosthetic methyl methacrylate rib-like reconstruction after the chest wall major resections. Patients and Methods: We evaluated 20 patients, from January 2004 to December 2011, treated at the Fondazione IRCCS Istituto Nazionale dei Tumori of Milano, with primary or metastatic tumors of the chest wall,who underwent surgery with reconstruction by a methacrylate shield shaped prosthesis on a Marlex mesh (CAST)+ /-myo-cutaneous flap. We collected all the clinical population data, the comorbidities , the integrated treatments, the intra and post-operative data (blood, plasma, albumin, transfusions , amount of drained liquids) and complications. Results: The median follow-up time was 3,7 years and the overall survival was 100% at 1 year, 85% at 2 years and 70% at 5 years. The most important complications after this surgery were the post-operative bleeding and proteins loss with need of blood, plasma and albumin transfusions, the flap ischemia or infection. Conclusion: This rigid prosthetic reconstruction is an anatomic and physiologic system, which could represent the evolution, in chest wall surgery, from simple substitution to armonic rimodelling and allows to get the oncological radicality also in maximal resections , such as hemi-thoracectomy.
