An experimental test system including the oil circulation system and the gas circuit system has been designed and built to explore the effects of the lubricating oil flow rate on the performance of a single-screw compressor, used in a portable natural gas liquefaction process. Outlet pressure, outlet volumetric flow rate, volumetric efficiency, and specific power rate are the parameters for evalua

All-inorganic CsPbBr3 perovskite colloidal quantum dots have recently emerged as a promising material for a variety of optoelectronic applications, among others for multiphoton-pumped lasing. Nevertheless, high irradiance levels are generally required for such multiphoton processes. One strategy to enhance the multiphoton absorption is taking advantage of high local light intensities using photoni

Initiating the gain process in a free-electron laser (FEL) from an external highly coherent source of radiation is a promising way to improve the pulse properties such as temporal coherence and synchronization performance in time-resolved pump-probe experiments at FEL facilities, but this so-called "seeding" suffers from the lack of adequate sources at short wavelengths. We report on the first suc

Macromolecular crowding in biological media is an essential factor for cellular function. The interplay of intermolecular interactions at multiple time and length scales governs a fine-tuned system of reaction and transport processes, including particularly protein diffusion as a limiting or driving factor. Using quasielastic neutron backscattering, we probe the protein self-diffusion in crowded a

Abstract: We consider improving Powheg+Minlo simulations, so as to also render them NLO accurate in the description of observables receiving contributions from events with lower parton multiplicity than present in their underlying NLO calculation. On a conceptual level we follow the strategy of the so-called Minlo′programs. Whereas the existing Minlo′framework requires explicit analytic input from

In the numerical integration of nonlinear autonomous initial value problems, the computational process depends on the step size scaled vector field hf as a distinct entity. This paper considers a parameterized transformation hf↦hf∘(I-γhf)-1,and its role in the finite step size stability of singly diagonally implicit Runge—Kutta (SDIRK) methods. For a suitably chosen γ> 0 , the transformed map is L

The accuracy of pore size distributions (PSD) obtained from gas adsorption and cryoporometry is compromised by the presence of advanced adsorption and advanced melting effects, respectively. In order to improve PSD accuracy, it is necessary to know the extent of such effects. In this work cryoporometry and adsorption have been combined to study the onset of advanced melting effects in a sample par

This paper presents a measurement of the double-differential cross section for the Drell-Yan Z/γ∗ → ℓ+ℓ− and photon-induced γγ → ℓ+ℓ− processes where ℓ is an electron or muon. The measurement is performed for invariant masses of the lepton pairs, mℓℓ, between 116 GeV and 1500 GeV using a sample of 20.3 fb−1 of pp collisions data at centre-of-mass energy of s=8 TeV collected by the ATLAS detector a

All-inorganic colloidal perovskite quantum dots (QDs) based on cesium, lead, and halide have recently emerged as promising light emitting materials. CsPbBr3 QDs have also been demonstrated as stable two-photon-pumped lasing medium. However, the reported two photon absorption (TPA) cross sections for these QDs differ by an order of magnitude. Here we present an in-depth study of the TPA properties

This brief presents an on-chip memory subsystem for massive multiple-input-multiple-output (MIMO) baseband processing at the base station. In massive MIMO systems, the required memory bandwidth and capacity are orders of magnitude higher than those used in conventional wireless systems, due to the large number of serving antennas. These are further combined with design targets on low access latenc

The chapter provides an overview of the development of the Muslim presence in Western Europe focussing on the period after World War II. The discussion deals with the experiences of Muslims in 19 countries which were located West of the “iron curtain” during the Cold War era (1946/1947–1989) and were therefore integrated in the capitalist world order and politically aligned with the USA. Beginning

We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies). A diverse set of process routes will be necessary to produce all intermediates and commercial products. In

Aluminum matrix fly ash (AMFA) cenosphere composites were fabricated using the stir casting technique. The used type of fly ash cenosphere, which accounted for over 60% in all fly ash particles, was in narrow and small size (2-30 μm). During synthesis, effects of several key technological parameters on microstructure and properties were investigated using orthogonal experimental design. The optima

The notion of Cloud RAN is taking a prominent role in narrative for the next generation wireless infrastructure. It is also seen as a mean to industrial communication systems. In order to provide reliable wireless connectivity for industrial deployments, by conventional means, the cloud infrastructure needs to be reliable and incur little latency, which however, is contradictory to the stochastic

Syfte: Syftet med vår studie är att belysa ifall genus har någon påverkan på revisorers bedömningar av väsentlighet för att i så fall skapa en medvetenhet om hur eventuella skillnader kan påverka bedömningen. Teoretiska perspektiv: Socialiseringsteori med genusfokus. De flesta mönster i kvinnligt och manligt beteende beror på socialisering snarare än de biologiska skillnaderna. Detta ligger delvisPurpose: The aim of our study is to elucidate whether gender has any effect on the auditor’s assessment of materiality in order to create an awareness on how any differences might affect the assessment. Theoretical perspectives: socialization theory with gender focus (gender differences depend more on social factors than biological) which partly explains the theory of women being more risk-averse

Forskning har visat att arbetstillfredsställelse har gynnsamma effekter för både organisation och individ samt att det finns ett samband mellan arbetstillfredsställelse och olika faktorer som ingår i medarbetarskap. Till författarnas kännedom har inte någon tidigare studie undersökt saAbstract The purpose of this study was to examine the relationship between employeeship and job satisfaction. Research has shown that job satisfaction has favorable effects for both the organization and the individual. It has also shown that job satisfaction and variables seen as part of employeeship correlate. However, to the knowledge of the authors no previous study has been performed to examin
