Inför museets högtidliga invigning den 28 september 1918, utdelades denna skrift som innehåller sju olika uppsatser med material hämtat ur museets samlingar.
Massive star clusters are observed in galaxies spanning a broad range of luminosities and types, and are assumed to form in dense gas-rich environments. Using a parsec-resolution hydrodynamical simulation of an isolated gas-rich low-mass galaxy, we discuss here the non-linear effects of stellar feedback on the properties of star clusters with a focus on the progenitors of nuclear clusters. Our sim
We combine parallaxes from the first Gaia data release with the spectrophotometric distance estimation framework for stars in the fifth RAVE survey data release. The combined distance estimates aremore accurate than either determination in isolation - uncertainties are on average two times smaller than for RAVE-only distances (three times smaller for dwarfs), and 1.4 times smaller than TGAS parall
The failing ecosystem services in Thika-Chania catchment is manifested in the deterioration of water quality, sedimentation of reservoirs, and subsequent increase in water treatment costs due to high turbidity. The services can be restored by implementing relevant soil and water conservation practices to enhance flow regulation and control sediment yield. The impacts of contour farming and filter
"Läsåret 1918 skall alltid stå som ett märkesår för Historiska museet. Det betecknar de historiska samlingarnas inflyttning i en egen institutionsbyggnad, det forna zoologiska museets. Byggnadens förändring, till vilken medel beviljats av riksdagen, tog sin början i slutet av år 1917, men på grund av mellankommande strejk och blockad avslutades byggnadsarbetet först i september 1918 eller samtidig
Two-particle pseudorapidity correlations are measured in sNN=2.76TeVPb+Pb, sNN=5.02TeVp+Pb, and s=13TeVpp collisions at the Large Hadron Collider (LHC), with total integrated luminosities of approximately 7μb-1, 28 nb-1, and 65 nb-1, respectively. The correlation function CN(η1,η2) is measured as a function of event multiplicity using charged particles in the pseudorapidity range |η|<2.4. The corr
Skrift utgiven den 1 maj 1910, i samband med återöppnandet av de nyordnande avdelningarna av universitetets konstmuseum, målerisamlingen i universitetets övervåning och skulptursamlingen i bottenvåningen (under aulan).
High-precision measurements by the ATLAS Collaboration are presented of inclusive W+→ ℓ+ν, W-→ ℓ-ν¯ and Z/ γ∗→ ℓℓ (ℓ= e, μ) Drell–Yan production cross sections at the LHC. The data were collected in proton–proton collisions at s=7TeV with an integrated luminosity of 4.6fb-1. Differential W+ and W- cross sections are measured in a lepton pseudorapidity range | ηℓ| < 2.5. Differential Z/ γ∗ cross se
Results of a search for physics beyond the Standard Model in events containing an energetic photon and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. As the number of events observed in data, corresponding to an integrated luminosity of 36.1 fb- 1 of proton–proton collisions at a centre-of-mass energy of 13TeV, is in agreement with the Standard
The development of large, software-intensive systems is a complex undertaking that we generally tackle by a divide and conquer strategy. Companies thereby face the challenge of coordinating individual aspects of software development, in particular between requirements engineering (RE) and software testing (ST). A lack of REST alignment can not only lead to wasted effort but also to defective softw
Nuytsia floribunda, was first described in print by Jacques Labillardière in a work from 1805 – Novae Hollandiae Plantarum Specimen – under the name of Loranthus floribundus. The name aimed at describing the colorful flowering, on a tree unique in the plant world through its hemiparastic way of living, developing of haustoria not seen elsewhere. Labillardière had observed the species on a journey
Software Engineering activities are information intensive. Research proposes Information Retrieval (IR) techniques to support engineers in their daily tasks, such as establishing and maintaining traceability links, fault identification, and software maintenance. We describe an engineering task, test case selection, and illustrate our problem analysis and solution discovery process. The objective o
During the past decade it has become evident that immunological, infl ammatory and vascular processes play an important role in the etiology and pathogenesis of various neuro-degenerative diseases. Alzheimer's disease (AD) is a complex and genetically heterogeneous disease that is the most common form of dementia and aff ects up to 15 million individuals worldwide. Th e presenting pathology of AD
The worldwide growing demand for whey proteins and derivatives requires more efficient and sustainable whey protein production processes. Whey is an important by-product from cheese manufacturing. In whey industry membrane processes such as microfiltration, ultrafiltration, nanofiltration and reverse osmosis are well-established to concentrate, fractionate and purify whey proteins as well as whey
Fouling is a constant challenge in membrane-based technologies. As conventional fouling monitoring and control methods are often based on process performance or product quality, they might reveal fouling so late that it has already damaged the membrane in severe and non-reversible way. Thus, surface sensitive online monitoring techniques capable of providing early warning capacity and information
Measurements of jet activity in top-quark pair events produced in proton–proton collisions are presented, using 3.2 fb- 1of pp collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. Events are chosen by requiring an opposite-charge eμ pair and two b-tagged jets in the final state. The normalised differential cross-sections of top-quark p
To assess the benefits of introducing Agile practices, it is important to get a clear understanding of the baseline situation, i.e. the situation before their introduction. Without a clear baseline, we cannot properly assess the extent of impacts, both positive and negative, of introducing Agile practices. This paper provides a preliminary guideline to help researchers in capturing and reporting b
Software developing organizations strive to achieve flexibility to maintain a competitive advantage. There is no common understanding of what characterize flexibility for a software organization beyond the scope of the software product. Without a common understanding, it is difficult to evaluate the degrees of flexibility of software development approaches. The aim of this literature review is to
