Abstract in UndeterminedRenewable energy flows are very large in comparison with humankind’s use of energy. Therefore, in principle, all our energy needs, both now and into the future, can be met by energy from renewable sources. Technologies exist that convert renewable energy flows to modern energy carriers or directly into desired energy services. Technological development during the last decad

The human genome, in common with all mammalian genomes, carries a high load of inheritable retroviral sequences. We have identified and characterized a novel family of these endogenous retroviruses and have named this family HERV-F as based on the primer binding sites of three members. The HERV-Fs are C-type endogenous retroviruses that have unique gag, pol and env regions that are, based on phylo

It is generally assumed that whereas referential nominal phrases are at least of DP size, predicative nominal phrases are structurally smaller. However, this paper argues that at least in Scandinavian, predicative nominal phrases as well as referential nominal phrases can be bigger than, equal to, or smaller than DP. Hence, the only consistent difference between nominal arguments and nominal predi

Various applications need an electric machine that can provide a wide range of torque over a broad range of rotation speed and temperature. Dynamic testing, where the machine acceleration is compared to the deceleration slope, allows to scan through a wide scope of operation points with insignificant temperature rise. Therefore, the goal of this paper is to analyse the consistency of the rapid exp

Results related to time-mean pressure distributions around a circular cylinder in cross-flow are presented and discussed briefly with special emphasis on the effect of relative pressure hole size and the position of separation. Experiments cover Reynolds numbers from $0.2 imes 10^3$ to $2.1 imes 10^5$.

Abstract The present work investigates i) the occurrence and removal of pharmaceuticals at Swedish WWTPs, and ii) potential causes for differences in the removal efficiency of pharmaceuticals at wastewater treatment plants. Particular attention is directed at the biological treatment and the pharmaceutical removal capacity per unit biomass of activated sludges and carrier biofilms of different or

Boken skildrar hur byn Dannäs i västra delen av Småland växer fram ur ett förmedeltida samhälle, hur byn utvecklas och så småningom försvinner. Den visar också hur politiska skeenden speglas på lokalnivå och griper in i människors vardag. Mycket av innehållet är resultatet av omfattande studier i arkiv, till exempel skattelängder och kyrkböcker, men också äldre kartor. Boken är relevant, både fak

Long-distance migration is a strategy some animals use to survive a seasonally changing environment. To reach favorable grounds, migratory animals have evolved sophisticated navigational mechanisms that rely on a map and compasses. In migratory insects, the existence of a map sense (sense of position) remains poorly understood, but recent work has provided new insights into the mechanisms some com

An efficient method for increasing the dilution rate of brine water discharged into the sea is an inclined negatively buoyant jet from a single port or a multi-diffuser system. Such jets typically arise when brine is discharged from desalination plants. Two small-scale experimental studies were conducted to investigate the behaviour of a dense jet discharged into lighter ambient water. The first e
