Impact of harvest intensity on long-term base cation budgets in Swedish forest soils

Abstract in UndeterminedThe effects of harvesting on the long-term mass balances of calcium (Ca), magnesium (Mg) and potassium (K) were evaluated on a regional level in Sweden. A new high-resolution weathering database was used together with estimates of total deposition, losses through harvest and leaching. Estimates were made for pine and spruce separately and for two harvesting intensity scenar

Ikke kun grøn revolution

Abstract in Danish At indisk landbrug stik imod forventningerne har udviklet sig positivt efter selvstændigheden, er ikke blot et resultat af den grønne revolution. Det skyldes i lige så høj grad statens aktive indblanding og ikke mindst bøndernes kamp for jordreformer, fremgår det af denne analyse af sociale bevægelsers betydning for indiske landbrugsudvikling. Nye producentorienterede bondebevæg

Control of Dissolved Oxygen in Stirred Bioreactors

This report discusses control of dissolved oxygen in a bioreactor where the oxygen supply is manipulated using the stirrer speed. In batch and fed-batch cultivations the operating conditions change significantly which may cause tuning problems. Analysis using a linearized process model shows that the process dynamics is mainly affected by changes in the volumetric oxygen transfer coefficient $K_La

First Results from the Stopped Beam Isomer RISING Campaign at GSI

The first results from a series of experiments focused on the study of the internal structure of nuclei at the extremes of N:Z ratio using isomer spectroscopy are reported. These experiments represent the first of the Stopped Beam section of the Rare Isotopes Investigations at GSI (RISING) project. Exotic nuclei were synthesized using relativistic projectile fragmentation of similar to 500 -> 1000

The inner world of a simple robot

The purpose of the paper is to discuss whether a particular robot can be said to have an 'inner world', something that can be taken to be a critical feature of consciousness. It has previously been argued that the mechanism underlying the appearance of an inner world in humans is an ability of our brains to simulate behaviour and perception. A robot has previously been designed in which perception

Regulation of skeletal muscle PPAR delta mRNA expression in twins

Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors regulating the expression of genes involved in lipid and glucose metabolism in a complex and to some extent unknown manner. Our aim was to study the impact of different factors on PPAR delta mRNA expression in human skeletal muscle on one side, and the impact of PPAR delta mRNA expression on these factors, including glucose

The accuracy and efficacy of screening tests for Chlamydia trachomatis: a systematic review

Screening women for lower genital tract infection with Chlamydia trachomatis is important in the prevention of pelvic inflammatory disease, ectopic pregnancy and infertility. This systematic review aims to state clearly which of the available diagnostic tests for the detection of C. trachomatis would be most effective in terms of clinical effectiveness. The review included all studies published fr

Context And Comprehension - A Neurolinguistic And Interactional Approach To The Understanding Of Semantic Pragmatic Disorder

Abstract in French Au cours de la preacutesente eacutetude nous faisons la description systeacutematique, du point de vue neurolinguistique et interactionnel, de deux enfants de sexe feacuteminin souffrant de deacutesordres seacutemantico-pragmatiques, ces derniers formant un sous-groupe au sein du groupe des deacutesordres speacutecifiques les plus aigus du deacuteveloppement du langage. Nous avaIn the present study we provide thorough descriptions of two children with a semantic-pragmatic disorder, a subgroup within the group of specific and severe developmental language disorders, from a neurolinguistic and interactional perspective. We argue that the pragmatic problems, at least in these two girls, are most probably secondary to their semantic'conceptual deficit. If sufficient contextu

Metalloantibiotic Mn(II)-bacitracin complex mimicking manganese superoxide dismutase

Superoxide dismutase (SOD) activities of various metallobacitracin complexes were evaluated using the riboflavin-methionine-nitro blue tetrazolium assay. The radical scavenging activity of various metallobacitracin complexes was shown to be higher than those of the negative controls, e.g., free transition metal ions and metal-free bacitracin. The SOD activity of the complex was found to be in the

A Study of Spreading of Vanadia on Titania Polymorphs Using Mechanical Mixtures

Mechanical mixtures of V2O5 and each of the three titania polymorphs TiO2(B), anatase and rutile were heated in air at 450°C. Spreading of vanadia was found to occur on all three polymorphs. After 36 hours of heating, coverage with interacting vanadia (the part that is insoluble in aq. NH3) on TiO2(B), anatase and rutile, respectively, was 54, 48 and 38 % of a theoretical monolayer. Raman spectra

Space wars and the new urban imperialism

Popular AbstractAvhandlingen analyserar sentida urbana förändringar ur perspektivet kampen om rummet, här kallat 'space wars'. Fokus är på investeringsflöden inom den kommersiella fastighetsmarknaden, förändringar inom urbanpolitik, förändring inom stadens socialgeografi, och relationer mellan dessa tre aspekter. Empiriskt bygger avhandlingen på studier av data rörande utländska investeringar, arkThe dissertation analyzes recent urban transformations through the lens of space wars. The main focus is on investment flows in the commercial property market, changes in urban governance and changes in social geography, and how these three aspects are related. Drawing on cross border investment data, archive studies, interviews with key actors and street walking experiences in Copenhagen, Lisbon
