2. 1. Seed dynamics and the ecological restoration of hill slopes of Kondoa Irangi, Central Tanzania

   Author : Herbert V. M. Lyaruu; Ingvar Backéus; Jerry Skoglund; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; anemochorous; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Ecological Botany; Ekologisk botanik;

   Abstract : Improper agricultural practices such as bill slope cultivation, extensive clearing of vegetation using fire over a long period, and to some extent overgrazing have converted the once fertile hill slopes of Kondoa Irangi in central Tanzania into unproductive marginal land. It is 25 years now since reclamation measures were introduced to save the hills from further degradation, but the regeneration process, has been rather slow. READ MORE

4. 2. Numerical and modelling aspects of large-eddy and hybrid simulations of turbulent flows

   Author : Matteo Montecchia; Arne V. Johansson; Gert Brethouwer; Stefan Wallin; Dominic Von Terzi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; wall-bounded flows; large-eddy simulation; SGS modelling; OpenFOAM; hybrid RANS-LES; Engineering Mechanics; Teknisk mekanik;

   Abstract : In this study, the explicit algebraic sub-grid scale (SGS) model (EAM) has been extensively validated in wall-resolved large-eddy simulations (LES) of wall-bounded turbulent flows at different Reynolds numbers and a wide range of resolutions. Compared to eddy-viscosity based models, the formulation of the EAM is more consistent with the physics and allows to accurately capture SGS anisotropy,which is relevant especially close to walls.

5. 3. A city on a hill cannot be hidden: Function and symbolism of Ancient Greek akropoleis

   Author : Robin Rönnlund; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; Antik historia; Klassisk arkeologi; akropolis; acropolis; citadel; hillfort; fortifications; polis; city state; Ancient Greece; archaeology; monumentality; Thessaly; Boeotia;

   Abstract : En akropolis (plur. akropoleis), en befäst kulle högt över en antik grekisk stad, utgör en av de mest välkända vyerna från antiken, men ingen har än studerat akropoleis systematiskt. READ MORE

6. 4. Interventions for improved prescribing and dispensing of medicines in Nepal, Thailand and Vietnam

   Author : John C Chalker; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Dispensing; prescribing; intervention studies; rational drug use; antibioitcs; indicator studies; simulated client method; ARI; STD; Vietnam; Nepal; Thailand.;

   Abstract : Background: To find successful interventions to improve drug use, especially antibiotics, is a pressing need in low income countries. The objectives of the research are to explore current practice and knowledge of practitioners in the public and private sectors in resource poor countries, and experiment with different interventions to improve practices in the prescribing and dispensing of medicine.

7. 5. The optic tectum of the salmon:site of interaction of neurohormonal photoperiodic and neural visual signals. The GABAergic neuronal system and melatonin receptors

   Author : Marie Anzelius; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal anatomy; melatonin receptors; GABA; optic tectum; fish; brain; animal morphology; Djurs anatomi och morfologi;

   Abstract : Melatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. READ MORE
