Estimating catchment scale soil loss based on rainfall simulators is often hampered by the difficulty to scale up simulator results. Our objective was to develop and test a method for estimating catchment scale soil loss based on observed rainfall using a variable intensity rainfall simulator in an erosion-sensitive catchment in semiarid Tunisia. A 7-year period, 1992-1999, with observed sedimenta

To identify Escherichia coli genes potentially regulated by filamentous phage infection, we used oligonucleotide microarrays. Genome-wide comparison of phage M13-infected and uninfected E. coli, 2 and 20 min after infection, was performed. The analysis revealed altered transcription levels of 12 E. coli genes in response to phage infection, and the observed regulation of phage genes correlated wit

L’évolution à long terme de l’humidité relative interne, de la résistance et de l’hydratation ont été étudiées sur huit bétons en conservation étanche, à l’eau, pendant 28, 90 et 450 jours. Le rapport eau/ciment du béton oscillait entre 0,22 et 0,58. La moitié des bétons contenaient 10% de fumée de silice. Les échantillons consistaient en disques de 1 mètre de diamètre et de 100 mm d’épaisseur. Le

The aim of this population-based prospective study was to determine the incidence of limb fracture by site and gender in different regions of Europe. Men and women aged 50-79 years were recruited from population registers in 31 European centers. Subjects were invited to attend for an interviewer-administered questionnaire and lateral spinal radiographs. Subjects were subsequently followed up using

The high-resolution far-infrared absorption spectrum of the intermolecular HCl libration band nu(6)(1) (nu(B)) of the gaseous molecular complex (HCN)-C-12-HCl and the two isotopically substituted species (HCN)-C-13-HCl and (DCN)-C-12-HCl is recorded by means of static gas-phase Fourier transform far-infrared spectroscopy at 205 K using an electron storage ring source. The rotational structure of t

TiO2 (anatase), SiO2 and gamma-Al2O3 were used as supports for Co-, Cu-, Fe- and Mn-oxide with a loading of active phase corresponding to one theoretical layer. The catalysts were tested for the combustion of CO and toluene, and the best combinations with active phase and support were submitted to a deactivation test in a waste gas incinerator for 50 days. The catalyst screening showed that CuOx/T

Popular Abstract in Swedish Barns lek är ett väl beforskat område där forskare till exempel försökt förstå lek som företeelse, studerat lekens betydelse för lärande, arbetat fram metoder för lekpedagogik eller studerat lek så som den framstår för barnen. I denna studie av lek i förskolan fokuseras den styrning som äger rum i leken. Det teoretiska perspektivet utgörs av Foucaults maktanalys. UtgångThe purpose of the thesis is to shed light on pre-school as an arena for governmentality, where play is a tool for governing the child. The study focuses what in play-situations may become an object of governance and what techniques the teachers use to govern the children when they play. The theoretical framework is the work of Foucault and his perspective on power and knowledge. The empirical stu

Under rubriken Skeptiska betraktelser har uppsatser om skilda ämnen inom litteraturvetenskap samlats. Kontexters betydelser vid litteraturanalyser diskuteras, litteraturhistoriens berättande genomlyses, texter och bohemer och sjörövare får samsas med lyrikanalyser. Kvantitativa undersökningar uppvisas samtidigt som mediekulturens förhållande till den litterära kulturen undersöks. Dessa olika Skept

Protein C (PC) is activated to an essential anticoagulant enzyme (activated PC or APC) by thrombin (T) bound to thrombomodulin (TM), a membrane receptor present on the surface of endothelial cells. The understanding of this complex biological system is in part limited due to the lack of integration of experimental and structural data. In the work presented here, we analyze the PC-T-TM pathway in t

An experimental study was performed to investigate the dependency of particle size on the deposition rate. Polystyrene latex particles of two radii (0.23 and 0.38 mum) were deposited onto a glass surface covered with indium-tin oxide. Reduced deposition efficiency was observed for the larger particles, although an increase in the deposition efficiency was seen as that the diffusion boundary layer

OBJECTIVE: To determine the rate of 5-minute Apgar scores below 7 in term infants (at least 37 weeks) in Sweden during 1988-1997, evaluate the influence of obstetric risk factors on low 5-minute Apgar scores, and to study the infant prognosis regarding infant mortality, neonatal neurologic morbidity, and outcome. METHODS: Data were collected from the Swedish Medical Birth Registry 1988-1997, and t

We are facing a water crisis because the world’s water resources must supplya population of record size. Strategic use of water and utilisation of damsin some form will be an important part of the solution. The pressure for multiobjective utilisation of dams will increase. But if one and the same dam isto be employed for a number of purposes, conflicts of interest may arise. Whendams are to provid
