SASI07: Circular Economy – Managing Materials Sustainably The SASI07 Circular Economy – Managing Materials Sustainably an online course focusing on Circular Economy (CE); what CE is and how its emergence can be facilitated as the result of choices and strategies by suppliers, designers, businesses, policymakers, and all of us as consumers. How can we create a circular economy through sustainable m

We report abundance excesses of 1.2 and 2.6 dex, respectively, for vanadium and bromine in the hot, peculiar star 3 Cen A. Abundances for these two odd-Z elements have not been previously reported for this star. Taken with previous work, they strengthen the case of the origin of the abundance peculiarities by diffusion.
This paper presents a technique for reconstructing two interfering wavefronts by analyzing their 3D interference field pattern. The method is based on the numerical inverse problem and will present a robust algorithm for reconstructing of wavefronts. Several simulations are done to validate the proposed method.

The present contribution describes some simulations of the observation of binaries with GAIA. The results do not differ fundamentally from earlier estimates, e.g. in GAIA's Concepts and Technology Study Report (ESA-2000-SCI-4), but they are based on more realistic assumptions and much more extensive numerical work.
Barn och unga är en mycket utsatt grupp individer för vilka samhället har ett särskilt ansvar att ge stöd och skydd. Utgångspunkten är att sådant stöd ges i frivilliga former, men under vissa förutsättningar kan detta ske tvångsvis med stöd av lagen (1990:52) med särskilda bestämmelser om vård av unga. Enligt lagens 3 § kan ett tvångsingripande aktualiseras då den unge utsätter sin hälsa eller ut
As Tova Mark’s presidency comes to an end, she is getting ready to hand over the reins to Agnes Ask. We got a chance to speak with both of them about the past year and expectations of what is to come. Tova, you had been very active in the student life and LundaEkonomerna ever since you started here in Lund. This last year you stepped it up a level and became president just in time for your 30 year

There is a problem with overtraining when applying Artificial Neural Networks to a classification problem. One factor that strongly influences the overtraining is the network topology. Understanding the role of the network topology is therefore important to enable the creation of more efficient Artificial Neural Networks.
A selection of the latest and most frequently used PDFs is incorporated in Pythia8, including the MC-adapted PDFs from the MSTW and CTEQ collaborations. This thesis examines the differences in PDFs as well as the effect they have on results of simulations. The results are also compared to data collected by the CDF experiment.
We report on recent advances on the computation of the matrix elements of the electroweak penguins Q(7) and Q(8) which are relevant for the DeltaI = 3/2 contribution to epsilon'(K) in the chiral limit. The matching of scale and scheme dependences between Wilson coefficients and these matrix elements is done analytically at NLO in alpha(S).
An improved version of the “pop-corn” model for baryon production in quark and gluon jets is presented. With a reduced number of parameters the model reproduces well both production rates for different baryon species and baryon momentum distributions. Predictions are presented for a set of baryon-antibaryon correlations.
The dust detector system onboard Galileo has recoding dust impacts incircumjovian space since the spacecraft was injected into a bound orbitabout Jupiter in December 1995. This is the sixth in a series of papersdedicated to presenting Galileo and Ulysses dust data. We present datafrom the Galileo dust instrument for the period January to December 1996when the spacecraft completed four orbits about
The spectral analysis and data products in Data Release 16 (DR16; 2019 December) from the high-resolution near-infrared Apache Point Observatory Galactic Evolution Experiment (APOGEE)-2/Sloan Digital Sky Survey (SDSS)-IV survey are described. Compared to the previous APOGEE data release (DR14; 2017 July), APOGEE DR16 includes about 200,000 new stellar spectra, of which 100,000 are from a new south
Carbon is the fourth most abundant element after hydrogen, helium and oxygen. It is a product of stellar nucleosynthesis as well as it being an important bio signature for life; this makes the analysis of carbon very fundamental. The origin of carbon and the relative contributions from massive and low-to-intermediate mass stars in producing it is still under debate. The principal focus of this the
The Gaia-ESO Survey is a large public spectroscopic survey that aims to derive radial velocities and fundamental parameters of about 10(5) Milky Way stars in the field and in clusters. Observations are carried out with the multi-object optical spectrograph FLAMES, using simultaneously the medium-resolution (R similar to 20 000) GIRAFFE spectrograph and the high-resolution (R similar to 47 000) UVE
Abstract in Undetermined Vi problematiserar den kritik mot föreläsningsbaserat lärande vid universitet och högskolor, som är vanlig i dagens pedagogiska diskussioner. Vi baserar vårt arbete på enkätundersökningar och på djupintervjuer av studenter på grundutbildningskurser i fysik vid Lunds universitet och Kungliga Tekniska högskolan. Vi anser att den rådande bilden av föreläsningens värde bör nya
