Aircraft maintenance and repair organizations (MROs) have to be competitive and attractive for both existing and new customers. The aircraft ground time at MROs should be as short as possible and cost effective without reducing the quality of the work. Process optimization in MROs requires the continuous improvement of processes and the elimination of non-value-added activities during maintenance

From an early age, humans intuitively expect physical objects to obey core principles, includingcontinuity (objects follow spatiotemporally continuous paths) and solidity (two solid objects cannotoccupy the same space at the same time). These 2 principles are sometimes viewed as deriving from asingle overarching “persistence” principle. Indeed, violations of solidity where one solid object seem-in

Perceiving object motion during self-movement is an essential ability of humans. Previous studies have reported that the visual system can use both visual information (such as optic flow) and non-visual information (such as vestibular, somatosensory, and proprioceptive information) to identify and globally subtract the retinal motion component due to self-movement to recover scene-relative object

Existing researches on two-row film cooling mainly focused on double-jet film cooling. However, researches on the effects by combining different kinds of hole shapes on film cooling performance are quite limited. In order to improve the film cooling effectiveness, the three-dimensional numerical method is utilized to investigate the effects of a novel structure composed of two-row holes with diffe

Vibrational structures of the C1s and N1s photoelectron spectra of gas-phase HCN have been investigated using monochromated third-generation synchrotron radiation. Both spectra exhibit resolved fine structure associated with several vibrationally excited states. In the C1s spectrum a single vibrational progression is observed, while the N1s spectrum is more complex. High-level ab initio calculatio

This thesis addresses drinking water quality and microbiology in full-scale drinking water distribution systems (DWDSs). It examines how UV irradiation and slow sand filters (SSFs) alter the water bacteriome, and how the biofilm in the DWDS affects the drinking water quality.In addition, the effects of installing a combined ultra­filtration and coagulation treatment stage on the pipe biofilm com­m

The current pandemic SARS-CoV-2 has required an unusual allocation of resources that can negatively impact chronically ill patients and high-complexity procedures. Across the European Reference Network on Pediatric Transplantation (ERN TransplantChild), we conducted a survey to investigate the impact of the COVID-19 outbreak on pediatric transplant activity and healthcare practices in both solid o

A method is proposed for realistic simulation of the breast ductal network as part of a computer three-dimensional (3-D) breast phantom. The ductal network is simulated using tree models. Synthetic trees are generated based upon a description of ductal branching by ramification matrices (R matrices), whose elements represent the probabilities of branching at various levels of a tree. We simulated

We propose a low-scale renormalizable trinification theory that successfully explains the flavor hierarchies and neutrino puzzle in the Standard Model (SM), as well as provides a dark matter candidate and also contains the necessary means for efficient leptogenesis. The proposed theory is based on the trinification SU(3)C×SU(3)L×SU(3)R gauge symmetry, which is supplemented with an additional flavo

The β decay of Hg208 into the one-proton hole, one neutron-particle Tl81208127 nucleus was investigated at CERN-ISOLDE. Shell-model calculations describe well the level scheme deduced, validating the proton-neutron interactions used, with implications for the whole of the N>126, Z

The notion of “contextual theology” has a long history, beginning with its gradual introduction in the “Fund for Theological Education”. Theology takes place as doing theology within contexts. A significant criterion for differentiating between, for example, contextual and constructive theology seems to lie in the valuation of how suffering, violence, and the struggle for social and environmental

We have characterized and compared the structures of ergosterol- and cholesterol-containing 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) membranes before and after interaction with the amphiphilic antifungal drug amphotericin B (AmB) using neutron reflection. AmB inserts into both pure POPC and sterol-containing membranes in the lipid chain region and does not significantly perturb the

Who is a child’s father? Is it the man who raised her, or the one whose genes she carries—or both? WIn this chapter, we look at the view that men who have raised children they falsely believed to be ‘their own’ have been victims of a form of fraud or are ‘false fathers’. We consider the question of who has been harmed in such cases, and in what the harm consists. We use conceptual analysis, a phil

Adiabatic laminar burning velocities for methane, n-heptane, and iso-octane blended with ammonia were experimentally determined using the heat flux method. The flames were stabilized at atmospheric pressure and at an initial temperature of 338 K, over equivalence ratios ranging from 0.7 to 1.4 and ammonia blending fractions in the binary fuel mixtures from 0 to 90%. These experiments are essential

Previous studies have shown that belief in the healthiness of organic food is a strong motive for buying organic. Typically, a positive relation between a nutritionally balanced diet (with respect to fruit, vegetables and meat) and organic consumption is also found. As market shares of organic food are much smaller than those of conventional food, consumers may face a trade-off between buying orga

We investigate the interfaces and polarity domains at the atomic scale in epitaxial AlN and GaN/AlN grown by hot-wall metal organic chemical vapor epitaxy on the carbon face of SiC. X-ray diffraction, potassium hydroxide (KOH) wet chemical etching, and scanning transmission electron microscopy combined provide an in-depth understanding of polarity evolution with the film thickness, which is crucia

Aims: To study incident narcolepsy in first- and second-generation immigrant groups using Swedish-born individuals and native Swedes as referents. Methods: The study population included all individuals registered and alive in Sweden at baseline. Narcolepsy was defined as having at least one registered diagnosis of narcolepsy in the Swedish National Patient Register. The incidence of narcolepsy in

In semiarid areas, the climate is characterized by strong spatiotemporal variability while the meteorological ground network is often very sparse. In this context, the spatial distribution of meteorological variables is thus a real issue for watershed hydrology, agronomy and the study of surface–atmosphere retroaction in these regions. The aim of this study is twofold: (1) to evaluate and to adapt
