Det försvunna fascinerar, ofta mer än det som finns i behåll. Bilden måste återskapas inom oss. Till ledning finns minnesbilder, rester av det försvunna, eller indirekta avtryck som foton, teckningar och beskrivningar. Att återskapa kräver efterforskningar och stimulerar fantasin. Särskilt lockande kan det vara att rekonstruera försvunna byggnader, konkreta avtryck av människor som levat tidigare.

In this study we compare two types of Large Eddy Simulation (LES) turbulent combustion models with experimental data for a low swirl stabilized turbulent lean premixed flame. Such flames are a great challenge to numerical simulations since they are unsteady and sensitive to boundary conditions, and details of the experimental set-up. The two classes of LES turbulent combustion models considered ar

The work presented in this paper deals with the use of green gluing (also known as wet gluing) as a mean to overcome the difficulties in making use of side boards for structural applications. By manufacturing laminated beams from unseasoned side boards several advantages are obtained. Beams were manufactured from side boards of approximately 25 mm thickness. The board width was 120 mm. The boar

Using the latest available data, this brief article attempts to provide the first regional decomposition analysis of CO2 emissions from fuel combustion. Covering eight regions of the world, determinants are estimated in relative and absolute terms for the period 1971-2010. We take the 2010 global surge in CO2 emissions as an entry point for the analysis. Overall, results show that most regions hav

Recent observations of the NN Serpentis post-common envelope binary system have revealed eclipse timing variations that have been attributed to the presence of two Jovian-mass exo-planets. Under the assumption that these planets are real and survived from the binary's main-sequence state, we reconstruct initial binaries that give rise to the present NN Ser configuration and test the dynamical stab

The Cone Calorimeter is a widely used advanced reaction to fire test, where a material’s fire properties is determined from test parameters such as time-toignition and heat release. The Cone Calorimeter has further a role in flame spread modelling, where data from the small-scale test can be used as input to models, or alternatively, the test can be used for validation purposes. In such cases, how

Based on published missionary reports and two conversion stories the missionary tactics and the used arguments from the Bible are presented alongside the Christian use of the conversion stories

Numerical simulations are performed for multiphase jets in crossflow. The flow solver uses an Eulerian/Lagrangian approach. Turbulence in the gas phase is modeled in the framework of large eddy simulation. The dispersed phase is handled using Lagrangian particle tracking. The model assumptions of solvers for Lagrangian particle tracking are critically assessed for typical flow conditions of spray

Telomere-associated DNA in Chironomus pallidivittatus contains tandemly repeated 340-bp units. We show that they are distributed among several subtypes of which we have characterized two, M1 and D1, with regard to base sequence, homogeneity, and intertelomeric distribution. Each subpopulation is highly homogeneous and the two subtypes have identical consensus sequences throughout 90% of their leng
