The flow field generated by the flow into a jet engine air-intake, with near ground effects, is considered. The axial inflow in the neighborhood of the ground generates a system of unsteady vortices. Some of these vortices extend from the air-intake towards the ground. Some of these vortices are strong enough to dislocate and even lift small objects from the ground up to the air-intake. The dynami

The near-field characteristics of a turbulent jet with moderate swirl generated by a fully developed, axially rotating pipe flow are investigated with LDV, time-resolved stereoscopic PIV measurements, as well as with large-eddy simulations. Large-scale vortical structures in either double, triple or even quadruple-helix configuration are found at the pipe exit but rapidly break down or amalgamate

A model to incorporate for aerodynamic 3-way (indirect) coupling between mono dispersed particles is proposed. The model is applied on particle laden jet flow and the results are compared with 2-way coupling. The particle drag coefficients are corrected based on the relative position of the particles. The correction factor is obtained from the pre-computed lookup tables. The particles are tracke

A measurement of jet substructure observables is presented using data collected in 2016 by the ATLAS experiment at the LHC with proton-proton collisions at s = 13 TeV. Large-radius jets groomed with the trimming and soft-drop algorithms are studied. Dedicated event selections are used to study jets produced by light quarks or gluons, and hadronically decaying top quarks and W bosons. The observabl

The need for comparative studies between experimental and numerical results exists due to the long lasting necessity for verification and validation. Accordingly, background oriented schlieren (BOS) provides a unique opportunity to perform non-intrusive quantification of density varying flows by means of an inexpensive and simple setup. As the optical flow based image processing algorithms are sho

We predictably believe that immense natural resources would generate large revenues and wealth within a country. Nevertheless, a lot of evidences show the contrary. Empirical studies find that resource abundance, economic collapse, civil wars, and political instability are well correlated. This indeed creates a complex puzzle as to why natural blessing has not always brought wealth in most resourc

The aim of this explorative study using a phenomenological approach is to have a closer look at individual perceptions of the phenomenon of intercultural communication and how it is constituted within at a work place. Eventual communication difficulties based on different cultural origins, as well as forms of interaction and working conditions in the enterprises, will be analyzed as possible reaso

BACKGROUND: With the increasing number of breast cancer (BC) diagnosed as a second primary malignancy after a first primary non-breast cancer (BCa-2), it is unclear about the familial risk of BC among women with a first-degree relative (FDR, parents or siblings) affected by a BCa-2.METHODS: In this Swedish nationwide cohort study, 5315 women with a FDR affected by BCa-2 and 115,048 women with a FD

Spectral aerosol light absorption is an important parameter for the assessment of the radiation budget of the atmosphere. Although on-line measurement techniques for aerosol light absorption, such as the Aethalometer and the Particle Soot Absorption Photometer (PSAP), have been available for two decades, they are limited in accuracy and spectral resolution because of the need to deposit the aeroso

(1) Autoantibodies to the leucine variant of neuropeptide Y (NPY-LA) have been found in individuals with type 1 diabetes (T1D). We investigated the association between the levels of NPY-LA and single nucleotide polymorphisms (SNP) to better understand the genetic regulatory mechanisms of autoimmunity in T1D and the functional impacts of increased NPY-LA levels. (2) NPY-LA measurements from serum a

Introduction Children with appendicitis often present with complicated disease. The aim of this study was to describe the clinical management of pediatric appendicitis, and to report how disease severity and operative modality are associated with short- and long-term risks of adverse outcome.
