Ethanol can be produced from lignocellulose by first hydrolysing the material to sugars, and then fermenting the hydrolysate with the yeast Saccharomyces cerevisiae. Hydrolysis using dilute sulphuric acid has advantages over other methods, however, compounds which inhibit fermentation are generated during this kind of hydrolysis. The inhibitory effect of aliphatic acids, furans, and phenolic compo
Speckle is an unwanted noise in ultrasound images, and appears as returning echoes are coherently summed over the transducer surface. In Doppler applications, the total power of the received spectrum varies in a manner similar to speckle. This paper investigates the correlation of continuous-wave (CW) Doppler signals obtained from simultaneously transmitted carrier frequencies, when a slowly flowi
Popular Abstract in Swedish Magnetkameran är ett diagnostiskt instrument med vilket man kan ta skiktbilder av kroppen. Den började användas i sjukvården för drygt 20 år sedan och baseras på ett fysikaliskt fenomen som kallas för kärnmagnetisk resonans (MR). Detta innebär att vissa atomkärnor som placeras i ett starkt magnetfält kan avge en radiosignal när de utsätts för korta radiopulser. RadiosigContrast-enhanced magnetic resonance angiography (CE-MRA) is a diagnostic method for imaging of vascular structures based on nuclear magnetic resonance. Vascular enhancement is achieved by injection of a contrast medium (CM). Studies were performed using two different types of CM: conventional paramagnetic CM, and a new type of CM based on hyperpolarized (HP) nuclei. The effects of varying CM con
Popular Abstract in Swedish Stroke är en heterogen sjukdom som inkluderar främst hjärninfarkt samt hjärn- och hjärnhinneblödningar från sprucken pulsåderbråck. Stroke är den tredje största dödsorsaken i industriländerna efter hjärtinfarkt och cancer. Varje år drabbas t.ex. i USA cirka 700 000 personer av stroke och runt 230 000 av dessa är fatala. Behandlingsmöjligheterna är trots framsteg på senaIncreasing [K+]o is intimately coupled to progressive ischemia and reduced CBF. In isolated cerebral and mesenteric arteries, it was found that significant differences in the vascular responses to [K+]o exist. Among the species studied, human cerebral arteries were the most sensitive artery to increasing [K+]o. Rabbit basilar arteries, denuded from the endothelium, showed increased sensitivity to
I dagens samhälle är bristen på fysisk aktivitet, ohälsosamma matvanor, tobaksbruk och bruk av alkohol de största orsakerna till ohälsa. Livsstilsrelaterad ohälsa förorsakar stora kostnader för hälso- och sjukvården och är en stor belastning för sjukvårdspersonal. Genom att röra på sig, äta nyttig mat, undvika tobak och stora mängder alkohol skulle alla individer bli mer hälsosamma. Hälsosamt leva
Uppsatsen ämnar granska relationen mellan kognitiv terapi, här representerad av Judith S Becks texter, och samhället utifrån en poststrukturell förklaringsmodell. Motivet är att påvisa psykologins och i synnerhet kognitiv terapis position och inverkan inom samhällsdiskursen. I uppsatsen ämnas eventuella sanningsregimer undergrävas samt möjligheter för dekonstruktion inom kognitiv terapi att diskutThe essay intends to examine the relationship between cognitive therapy, represented by Judith S Beck's texts, and society from a poststructural viewpoint. The motive is to demonstrate psychologies, in particular cognitive therapies, position and influence within social discourse. I intend to undermine possible truthregimes and to discuss the potential for deconstruction within cognitive thera
This report contains a mapping of the different types of goods imported into Sweden by air during 2004. The process of the collection of statistical data resulted in a model. The model was developed with the purpose to make future updates easier and more accurate. Finally, the report contains a vulnerability analysis for the supply chain of pharmaceuticals in Sweden. The role of aviation was taken
The objective of this master’s thesis has been to develop a model for valuation and comparison be- tween SCA plants with reference to fire loss prevention work. The aim of this report has been ful- filled by analysing results from literature studies, interviews and questionnaires answered by per- sons experienced within fire loss prevention work and paper industry. The report resulted in a Loss Pr
This master thesis presents a qualitative model for performing a due diligence analysis of non- financial risks and their management, the DANFiRM model. The model includes a thinking process and a working procedure for identifying and evaluating the current non-financial risk exposure at the target enterprise and further required measures for altering risk exposure and risk management activities t
According to the legislation for accident prevention and protection, which took affect January 1st 2004, all Swedish municipalities have to establish plans of actions for accident prevention and the fire service. Municipal risk analyses should constitute the foundations for these plans of actions. The purpose of this report is to describe and meet the requirements on municipal risk and vulnerabili
