De första mikrosekunderna efter Big Bang (den stora smällen) tros det ha bildats något som kallas kvark-gluonplasma. Kvark-gluonplasma består av kvarkar och gluoner, som är så kallade elementärpartiklar. Elementärpartiklar är de minsta kända beståndsdelarna. Kvarkarna bygger upp större partiklar som kallas hadroner, exempel på hadroner är protonen och neutronen som atomkärnan består av. Det som håIn high-energy heavy-ion collisions, a state of matter called quark-gluon plasma (QGP) can be created. The production of particles from the QGP can be described by different models, one of these is the blast-wave model. The blast-wave model describes the production of particles from the QGP, not from jets. The model was fitted to the existing transverse momentum spectra (pT) for pions, kaons and p

The “neurotrophic hypothesis of depression” posits that low levels of brain-derived neurotrophic factor (BDNF) are associated with Major Depressive Disorder (MDD). Low levels of BDNF have also been found in individuals with suicide attempts, in MDD or other disorders, suggesting that low BDNF may also be associated with suicidality. We assessed serum BDNF in 68 physically healthy and unmedicated (

Bulgarian apico-alveolar stops and Swedish dorsovelar stops are palatalized when adjacent to front vowels. An X-ray motion film study of these assimilations (part of an ongoing investigation of the temporal organisation of coarticulation and assimilation) is presented. Two issues are examined, extrinsic vs intrinsic production of assimilation and feature spreading vs. coproduction. The articulator

Abstract in UndeterminedObservations of chemically peculiar (CP) stars have been conducted for decades and have revealed a variety of spectrum anomalies, most prominent among them are line enhancements of heavy elements. The earlier observations were limited to the optical region and the use of less sensitive detectors, yet are responsible for much of our current characterization of the CP star ph

A business analyst who commences an investigation into design requirements for a new work system probably does not ‘label’ her inquiry process as research. However, a research perspective is needed if a productive learning spiral is to be established in which ‘useful’ systems can be created. Systematic, collaborative inquiry adopting an complex, open systems perspective is required in order to est

We present a new experimental method for the measurement of the compressibility of cells by analysis of free flow acoustophoresis separation data.

We report a new method to select the optimal actuation frequencies in bulk acoustophoresis devices, by means of differential impedance spectrum analysis measured via the actuating piezoelectric transducer (piezo). The impedance spectra is rich of large spurious resonance peaks originating from bulk resonances not related to the channel resonance, Fig. 1a, why direct measurement of the piezo impeda

We have studied a selection of factors influencing the damage of DNA in nanochannels during fluorescence imaging. For cutting and nicking of DNA we show that the DNA is shortened during imaging. To avoid photodamage over the course of several hours of a typical experiment, we demonstrate the importance of an oxygen free gas to propel the buffer solution through the device. Finally, by varying the

This study aims to examine the effectiveness of the narrative tools in the modern Arabic poetry and take Al-baradony poetry as a model because it is a fertile field for academic studies and is as diverse as the curriculum to be studied by way of applications It has been studied in some respects and is still under taken for reasons. This study tries to examine the phenomenon of narrative style Al-b
