We estimated total lake plant biomass and primary net production in two shallow Swedish lakes that differ in nutrient loading and plant form dominance. In clearwater Lake Krankesjon (10 mu g chlorophyll a L-1), submerged macrophytes contributed more than phytoplankton and epiphyton to the estimated plant biomass. Estimated net primary production during May to September was 90-130, 1.2, and 14 g C

The equilibrium terrestrial biosphere model BIOME3 simulates vegetation distribution and biogeochemistry, and couples vegetation distribution directly to biogeochemistry. Model inputs consist of latitude, soil texture class, and monthly climate (temperature, precipitation, and sunshine) data on a 0.5 degrees grid. Ecophysiological constraints determine which plant functional types (PFTs) may poten

Popular Abstract in Swedish Avhandlingen undersöker de kontexter inom vilken Malmö Stadsteaters ungdomsgrupp Unga Teatern existerade, bl a kulturpolitik, skol- och läroplansutveckling och reception. Den övergripande frågeställningen är huruvida det under vissa perioder funnits en genomgripande estetik. Nio uppsättningar analyseras med avseende på pjästext, iscensättning, arbetsprocess och receptioThis dissertation investigates whether Unga Teatern, a theatre group for children and youth at Malmö City Theatre, had an aesthetic profile of its own. It focuses on three sections: the theme of fairy tales and myths under the artistic direction of Ronnie Hallgren (19977-83), his staging of English plays (1982 -84) and the avantgarde production for children and youth under the direction of Karin P

The outdoor environment is deteriorating in many tropical cities due to rapid urbanization. This leads to a number of problems related to health and well-being of humans and also negatively affects social and commercial outdoor activities. The creation of thermally comfortable microclimates in urban environments is therefore very important. This paper discusses the influence of street-canyon geome

Objective. To study the distensibility and the diameter of the abdominal aorta and the common carotid artery (CCA) in patients with rheumatoid arthritis (RA), and investigate the relation between mechanical properties of these arteries and disease severity. Methods. One hundred and one patients with RA (33 consecutive cases with extra-articular manifestations, and 68 subjects with non-extra-artic

Neuroblastoma is a childhood tumour derived from the sympathetic nervous system. Although most children with neuroblastoma initially respond to treatment, approximately 50% of these patients relapse with multidrug-resistant tumours. Arsenic trioxide (As2O3) has been used for centuries to treat different clinical disorders including malignancies. This drug has now attracted new attention since it h

Background and Purpose - The subventricular zone in the adult brain is identified as an endogenous resource of neuronal precursors that can be recruited to adjacent lesioned areas. The hypothesis was tested that postischemic environmental enrichment might enhance subventricular zone cell genesis. Methods - A cortical infarct was induced in adult spontaneously hypertensive rats by ligating the midd

Background: We have previously demonstrated that patients with Crohn's disease ( CD) of long duration have signs of autonomic neuropathy. The aim of this study was to examine whether autonomic neuropathy is an early manifestation of CD, or a sign appearing late in the course. Methods: Twenty patients, median age 40 years, with a short duration of CD were included. Examination of autonomic reflexes

Popular AbstractI denna avhandling analyseras den svenska skogsbruksdebatten under nittonhundratalets tre sista decennier. De ideal och värderingar som genom det moderna skogsbrukets ideologi och praktik kom att råda i skogarna utmanades av miljörörelsen från sextiotalet och framåt. Till en början stod skogsnäringen och miljörörelsen mycket långt från varandra, men under nittiotalet började man näIn this dissertation, the Swedish forestry debate during the last three decades of the 20th century is analysed. The contents, values and underlying assumptions of the debate are investigated from a discoursive point of view. Ideals, methods and aesthetics are analysed, as they have been expressed throughout the debate. Modernity's focus on uniformity, order and culturalisation of nature is contra

Detailed numerical simulations of fires in road tunnels were carried out using the CFD code JASMINE. Fire tests performed in the Ofenegg tunnel have also been validated. A parametric study of fires in an arbitrary 300-m-long tunnel was made, in which the influence of fire size, tunnel width, ventilation and ground slope was investigated. The movement of hazardous temperature and smoke regions as a

Vertebral deformities are a common consequence of osteoporosis and are known to decrease quality of life. The Qualeffo-41 is a quality-of-life questionnaire especially developed for measuring quality of life in patients with vertebral deformities. It consists of 41 questions arranged in five domains: pain, physical function, social function, general health perception, and mental function. The obje
