Weathering rates of base cations are crucial in critical load calculations and assessments of sustainable forestry. The weathering rate on a single site with detailed geological data can be modelled using the PROFILE model. For environmental assessments on a regional scale, the weathering rates for sites are scaled into regional maps. The step from sites to regional level requires focus on the spa
A new class of block codes with low state complexity of their conventional trellis representations called double zero-tail terminated convolutional codes (DZT codes) is introduced. It is shown that there exist DZT-codes meeting the Varshamov-Gilbert bound on the minimum distance and having asymptotically optimal state complexity. Two ways of constructing DZT-codes are considered. Examples of DZT-c
We analysed and compared the functioning of UV-B screening pigments in plants from marine, fresh water and terrestrial ecosystems, along the evolutionary line of cyanobacteria, unicellular algae, primitive multicellular algae, charophycean algae, lichens, mosses and higher plants, including amphibious macrophytes. Lichens were also included in the study. We were interested in the following key asp
In a cross-sectional study of diabetic patients diagnosed at or after 30 years, and with different stages of retinopathy, factors such as duration of diabetes, treatment mode, metabolic control, blood pressure, and clinical signs of nephropathy were examined. The different stages of retinopathy used were absence of retinopathy, simplex, and severe retinopathy. Patients with simplex and severe reti
Lyme borreliosis (LB) is the most common vector-borne disease in the northern hemisphere, and southern Sweden is a highly endemic area. In over 70% of the cases, LB is represented by the non-disseminated cutaneous form erythema migrans (EM). This thesis has its focus on EM from a primary health care perspective in southern Sweden, including aspects on epidemiology, the clinical picture, gender dif
Graft copolymers containing poly(ethylene oxide) side chains on a polystyrene backbone have been synthesized. Styrene copolymers synthesized by free radical mechanism and containing between 5 and 15 mol % acrylamide or methacrylamide were used as backbones. The amide groups in the copolymers were ionized by using potassium tert-butoxide or potassium naphthalene, and grafting was achieved by utiliz
A method of analyzing & describing the acoustic properties of fricatives is developed & applied to the fricatives & to the fricative components of the affricates of Standard Chinese. The method consists of making f spectra using the Fast Fourier Transform & analyzing the spectra in terms of critical bands. Three measures are proposed for characterizing the fricative spectra: the ce
Myeloperoxidase ( MPO) is one of the major target antigens of antineutrophil cytoplasmic autoantibodies ( ANCA) found in patients with small-vessel vasculitis and pauci-immune necrotizing glomerulonephritis. To date, the target epitopes of MPO-ANCA remain poorly defined. Human MPO-ANCA do not typically bind mouse MPO. We utilized the differences between human and mouse MPO to identify the target r
A dispersion experiment, where the tracer SF6 Was released from line sources, was carried out within a young pine forest. Line sources made of silicone tubes were installed at different heights and distances from a tower. Vertical concentration profiles were measured on the tower and the samples were analysed with a gas chromatograph. The measured concentration profiles were compared to those calc
This article traces the reception of the the Swedish film Ingeborg Holm in 1913. The film created a fierce debate regarding the Swedish poor laws. This debate eventually led to changes in the law in 1918.
The portal appearance of enteral alpha-ketoglutarate (AKG) and the effect of enteral or parenteral AKG on portal net appearance of glucose, short-chain fatty acids, alanine, aspartate, glutamate, glutamine, proline and insulin were investigated in three growing pigs. During the experimental samplings the pigs were fed hourly with a standard feed mix with 5% glucose (control), 5% AKG (enteral) or n
Popular Abstract in Swedish Selektiv dorsal rhizotomi (SDR) är en effektiv operationsmetod som framgångsrikt minskar graden av spasticitet med bestående positiva effekter för barn med spastisk diplegia. Barn som genomgår SDR har svåra smärtor postoperativt, smärtan är relaterad till både den stora kirurgin med blocklaminotomin och nervrots manipulation. För att kunna ge en optimal smärtlindring ärSelective dorsal rhizotomy (SDR) is an effective operations method that successfully decreased the degree of spasticity with long lasting beneficial effects for children with spastic diplegia. Children undergoing SDR are postoperatively in severe pain, a pain related to both the extensive surgical exposure with multilevel laminotomy and the nerve root manipulation. To give an optimal pain relief,
Intim a-media thickness (IMT) is considered as a valuable marker of early atherosclerosis. We suggest a new algorithm for simultaneous measurements of absolute diameter at diastole, distension (diameter change), IMT at diastole and the intima-media compression (IMC) with a new fast, robust, high-resolution, and automatic algorithm utilizing the ultrasonic gray-scale information. The new algorithm
Ionizing radiation is a well-known risk factor for sarcoma development. To investigate whether radiation-associated sarcomas are characterized by chromosome aberrations that distinguish them from de novo sarcomas, we identified those patients in our series of more than 500 cytogenetically abnormal sarcomas that fulfilled the following criteria: (1) each patient should have been irradiated for anot
BACKGROUND: Pulmonary hypertension may result in significant morbidity and mortality after pediatric cardiac surgery. The objective of this study was to determine the incidence and outcome of severe pulmonary hypertension, defined as a ratio of pulmonary to systemic arterial pressure equal to or greater than 1.0, after cardiac surgery in children. METHODS: Data from all children younger than 18 ye
