Pentaklorfenol (PCP) är en klorerad aromatisk förening som användes flitigt för att behandla trä mot mikrobiell nedbrytning innan den blev förbjuden på 70-talet. På grund av dess höga löslighet förekommer PCP som en grundvattenförorening kring äldre sågverk. Hjortsberga i södra Sverige är ett exempel på denna typ av förorening och är det område som undersöks i arbetet. Förorenat grundvatten spridsPentachlorophenol (PCP) is a chlorinated aromatic compound that was commonly used for treatment of wood against microbial degradation before it got banned in the 1970s. Due to its solubility in water, PCP is a common groundwater contaminant around old sawmills, for example near Hjortsberga in southern Sweden where this study was performed.. The contaminated groundwater is spreading and leaking int

Enriched environment significantly enhances postischemic functional outcome. We have tested the hypothesis that housing in enriched environment stimulates gene expression for brain-derived neurotrophic factor. After ligation of the middle cerebral artery in male spontaneously hypertensive rats, they were housed in individual cages for 30h, then housed either in standard cages or in an enriched env

Popular Abstract in Swedish Cystisk fibros (CF) är en ärftlig sjukdom som orsakas av en defekt jonkanal. Denna defekt ger upphov till en onormal saltbalans i kroppen och följderna blir många. I lungorna och magtarmkanalen produceras ett väldigt segt slem vilket täpper till luftvägarna och medför andningssvårigheter. De slemfyllda lungorna klarar inte av att transportera upp slemmet och istället stCystic fibrosis is an inherited disease, caused by mutations of the cystic fibrosis transmembrane conductance regulator gene. The gene codes for a protein that serve as chloride channel. In cystic fibrosis, this protein is lacking or has a defect function resulting in a thick and sticky mucus of the airways. The altered airway environment promotes mucus and growth of pathogenic bacteria. A common

The influence of 10 wt.% mature compost was tested on the heavy metal leachate emissions from a calcium-rich municipal solid waste incineration air pollution control residue (MSWI APC). Apart from elongated columns (500 and 1250 mm), an otherwise norm compliant European percolation test setup was used. More than 99% of the metals Al, As, Cd, Cr, Cu, Fe and Ni were left in the APC residue after lea

This experimental study examines the influence of moisture variations on the load-bearing capacity of steel-timber dowel joints. The glulam specimens used to manufacture the joints were first exposed to controlled climate changes. After being stored in the climate chambers, holes were drilled and dowels were inserted. Then, the joints were loaded to failure. The main aim of this study was to inves

Organic farming may contribute substantially to future agricultural production worldwide by improving soil quality and pest control, thereby reducing environmental impacts of conventional farming. We investigated in a comprehensive way soil chemical, as well as below and aboveground biological parameters of two organic and two conventional wheat farming systems that primarily differed in fertiliza

We present a novel visibility algorithm for rendering motion blur with per-pixel anti-aliasing. Our algorithm uses a number of line samples over a rectangular group of pixels, and together with the time dimension, a two-dimensional spatio-temporal visibility problem needs to be solved per line sample. In a coarse culling step, our algorithm first uses a bounding volume hierarchy to rapidly remove

In vitro mechanotransduction studies, uncovering the basic science of the response of cells to mechanical forces, are essential for progress in tissue engineering and its clinical application. Many varying investigations have described a multitude of cell responses; however, as the precise nature and magnitude of the stresses applied are infrequently reported and rarely validated, the experiments

The aim of this study was to investigate myocardial wall motion using echocardiography and color-coded tissue velocity imaging and to generate a cardiac state diagram for evaluation of the duration of the pre- and post-ejection phases in asphyxiated fetal lambs. Six near-term lambs were partly exteriorized and brought to cardiac arrest through asphyxia. Echocardiography measurements were recorded

Fifty-one adolescent-onset anorexia nervosa (AN) cases recruited after community screening were compared with 51 age-, sex-, and school-matched cases with regard to personality disorders and autism-spectrum disorders (ASD)/empathy disorders at age 21 years. All 102 cases had originally been examined at a mean age of 16 years, slightly over a year after the reported onset of the eating disorder. St

The birth, growth and maturity of industries, sectors and technologies have spurred the curiosity of researchers as well as managers and policy makers for a long time. Intriguingly, the emergence of a new industry is a complex process including many different actors and with a high level of uncertainty related to technology, institutions and markets facing the actors involved. Empirically this b

We introduce a scalable observer architecture to estimate the states of a discrete-time linear-time-invariant (LTI) system whose sensors can be manipulated by an attacker. Given the maximum number of attacked sensors, we build on previous results on necessary and sufficient conditions for state estimation, and propose a novel multi-modal Luenberger (MML) observer based on efficient Satisfiability

Popular Abstract in Swedish Nematofaga svampar förekommer inom många grupper i svampriket och har den gemensamma förmågan att döda nematoder (millimeterstora rundmaskar) och använda dem som näring. Vissa arter är obligata parasiter, medan andra är fakultativa saprofyter, vilket innebär att de förutom att parasitera nematoder lever av dött organiskt material. Dessa svampar har, sedan de upptäcktes Nematophagous fungi possess various mechanisms for infecting nematodes, and are either obligate parasites or facultative saprophytes. Nematophagous fungi have a potential as biological control agents against plant- and animal-parasitic nematodes. Generally there has been little success in using these fungi in such a way, and one reason might be that too little is known about the ecology of the nem

The quantitative information in SPECT images is distorted by photon attenuation and contribution of photons scattered in the object. It is, therefore, important to know the distribution of different attenuating tissues in order to be able to perform a proper attenuation correction. A correction method, based on correcting one pixel at a time by using density maps and build-up functions, has been d

Organizations and individuals maintain and use an ever increasing amount of computer systems, either deployed locally, or in the cloud.These systems often store and handle vast amounts of data, some of which is sensitive and should be kept private.Regardless of where the data is located, there is a need to prevent data from falling into the wrong hands.To this end, this dissertation presents contr
