EPS production by Propionibacterium freudenreichii facilitates its immobilization for propionic acid production

Aims: Immobilization of microbial cells is a useful strategy for developing high cell density bioreactors with improved stability and productivity for production of different chemicals. Functionalization of the immobilization matrix or biofilm forming property of some strains has been utilized for achieving cell attachment. The aim of the present study was to investigate the production of exopolys

Towards an initial mass function for giant planets

The distribution of exoplanet masses is not primordial. After the initial stage of planet formation, gravitational interactions between planets can lead to the physical collision of two planets, or the ejection of one or more planets from the system. When this occurs, the remaining planets are typically left in more eccentric orbits. In this report we demonstrate how the present-day eccentricities

The impact of radiation feedback on the assembly of star clusters in a galactic context

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

Improved distances and ages for stars common to TGAS and RAVE

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

Effectiveness of Contour Farming and Filter Strips on Ecosystem Services

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

Historiska museet

"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

Measurement of forward-backward multiplicity correlations in lead-lead, proton-lead, and proton-proton collisions with the ATLAS detector

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|

Lunds universitets historiska museum

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).

Precision measurement and interpretation of inclusive W+ , W- and Z/ γ∗ production cross sections with the ATLAS detector

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

Search for dark matter at √s=13TeV in final states containing an energetic photon and large missing transverse momentum with the ATLAS detector

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

Assessing requirements engineering and software test alignment - Five case studies

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 – sydvästra Australiens unika mistelträd och dess upptäckthistoria

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

Large-scale information retrieval in software engineering - an experience report from industrial application

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

Adhesion molecules in dementia

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

Real time monitoring of whey foulants adsorption on polyethersulfone surface

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

Real-time fouling monitoring in food and biorefining industries – Needs and possibilities

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

Measurement of jet activity produced in top-quark events with an electron, a muon and two b-tagged jets in the final state in pp collisions at √s=13 TeV with the ATLAS detector

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
