The study aims at investigating the use of Landsat thematic mapper (TM) for mapping leaf area index (LAI) in coniferous and deciduous forests in southern Sweden. LAI has been estimated in the field with optical measurements, allometric equations, and litter-trap data, and empirical relationships between LAI estimates and satellite-measured reflectances have been analysed. Several common vegetation
Background Open abdomen (OA) treatment often results in difficulties in closing the abdomen. Highest closure rates are seen with the vacuum-assisted wound closure (VAWC) technique. However, we have experienced occasional failures with this technique in cases with severe visceral swelling needing longer treatment periods with open abdomen. Feasibility and short-term outcome of a novel combination o
Extraction systems for hydrophobically tagged proteins have been developed based on phase separation in aqueous solutions of non-ionic detergents and polymers. The systems have earlier only been applied for separation of membrane proteins. Here, we examine the partitioning and purification of the amphiphilic fusion protein endoglucanase I(core)-hydrophobin I (EGI(core)-HFBI) from culture filtrate
In Sweden a new red list was issued 2000, but there is no published list of the most important areas for biodiversity preservation. I use woodliving and red-listed beetles as indicators of “hot-spots” for biodiversity preservation, since these insects constitute a large proportion of the red-listed forest living species in Sweden. Based on museum and many large private collections of beetles from
A new type of triangular phase diagram has been developed in which both the volume fractions and the shrinkage modes can be visualised and compared for the consolidation process in the paper dryer. The triangular phase diagrams show the development of the solid, the liquid and the gas volume fractions as well as the shrinkage relative to either ideal or no shrinkage of the sheets. Analysis showed
Popular Abstract in Swedish Parkinsons sjukdom uppstår när celler som producerar signalsubstansen dopamin i hjärnan dör. Detta leder till att de drabbade patienterna blir stela, får långsamma rörelser, svårt att påbörja och avsluta rörelser och även skakningar i framförallt armar och händer. Idag finns inget sätt att bota sjukdomen. Dock finns det läkemedel som kan lindra symptomen. Den vanligasteThe main pathological feature in Parkinson's disease is the progressive loss of dopamine neurons in the midbrain, which in turn leads to the appearance of motor deficits such as akinesia/bradykinesia (loss/slowness of movements), rigidity, postural imbalance and tremor. To this day, there is no cure for the disease, but there are medications to relieve the symptoms. The gold standard medication is
Objective: Interstitial laser coagulation (ILC) of the prostate is a minimally invasive method for treating symptomatic benign prostatic enlargement (BPE). We performed a prospective randomized study to compare the clinical outcomes of ILC and transurethral resection of the prostate (TURP). Material and Methods: Between December 1997 and February 2000, 38 patients with moderate-to-severe symptomat
Peptidoglycan from Staphylococcus aureus mobilized CD66b in human neutrophils but did not upregulate surface activation markers in eosinophils. In addition, Toll-like receptor 2, implicated in the recognition of peptidoglycan, was detected on the surface of resting neutrophils but not on eosinophils. These findings suggest roles for neutrophils but not eosinophils in innate recognition of peptidog
The typical catalyst layers (CLs) in proton exchange membrane fuel cells (PEMFCs) are fabricated as random heterogeneous composites to meet the multifunctional requirements of transport phenomena and electrochemical activity. The employment of Pt nano-particles, carbonaceous substrates and Nafion ionomers in CLs allows effective diffusion of hydrogen and oxygen, transport and phase change of water
Indolyl substituted pyranyl- and cyclohexenyl molybdenum complexes were synthesised through stereoselective nucleophilic addition of indoles to the corresponding cationic 2H-pyran or cyclohexadiene molybdenum complex. Decomplexation of an allylic molybdneum complex by treatment with iodine gave 1-(4-iodo-2-cyclohexenyl)-1H-indole-3-carbonitrile in high regio-selectivity. A new method for preparati
When biomass is used to produce fuels and green products by thermochemical conversion, the ability to handle or remove the fine particle phase in the product gas is crucial. The product gas from biomass gasification contains relatively volatile organic compounds (“tar”) condensed on nonvolatile cores of, for example, aggregated soot particles and char. The problems are, for example, that particles
A statistical distribution for the number of CDMA RAKE fingers, N T, to be assigned in order to track a given percent of the total received power has been derived. The obtained distribution reveals a strong dependence of NT on the system bandwidth, the median RMS delay spread, its standard deviation and other environment specific parameters. Also, a statistical distribution for the fading width fw
A virtual reality (VR) experiment with 96 participants was carried out in a Cave Automatic Virtual Environment (CAVE) laboratory at Lund University to provide recommendations on the design of flashing lights at emergency exit portals for road tunnel emergency evacuation. A set of variables were investigated, namely 1) Colour of flashing lights, 2) Flashing rate, 3) The type of light source, 4) The
In the development of new food products, more knowledge is needed about the occurrence and quantity of food-borne pathogens in the food chain to be able to implement effective control measures and assure food safety. In addition, improved understanding of how environmental factors and food preservatives effect the microbial virulence expression in foods will enable the formulation of new strategie
In addition to being a key criterion of the sustainable development proviso, for business, the integration of social- and ecological considerations into decision-making is of growing importance for minimising future environmentally-related risk and associated economic costs, as well as gaining a share in growing markets favouring products and companies focusing upon social responsibility and ecolo
In an era of lifelong learning, empowerment of the learner becomes fundamental. Therefore ex-ploitation of the full potential of learning objects depends upon creation of an appropriate infra-structure to promote symmetrical control of inquiry. The learner needs to be empowered because learning is a discovery process and thus must be under his or her own control. In early stages of education it
Popular Abstract in Swedish Patienten med underbensamputation på grund av kärlsjukdom Långt före Kristi födelse var amputation av benet en känd operation. Anledningen till amputationen kunde vara kärlsjukdom, olycksfall, tumör eller medfödda missbildningar. I västvärlden idag utförs 90 % av amputationerna på grund av kärlsjukdom. Dessa patienter är äldre och sjukare än övriga benamputerade och meThe patient with unilateral trans-tribal amputation for vascular disease. Functional assessments, prognostic factors and cost of prostheses. The aims of the study were to focus on the functional ability of the dysvascular patient with unilateral trans-tibial amputation and the early rehabilitation period, defined here as the period between the amputation and the prosthetic fitting.
