The mechanism of hydrolysis of cellulose is important for improving the enzymatic conversion in bioprocesses based on lignocellulose. Adsorption and hydrolysis experiments were performed with cellobiohydrolase I (CBH I) and endoglucanase II (EG II) from Trichoderma reesei on a realistic lignocellulose substrates: steam-pretreated willow. The enzymes were studied both alone and in equimolar mixture

In this paper, a new approach for on-line monitoring and detection of abnormal readily biodegradable substrate (SS) and slowly biodegradable substrate (XS) concentrations, for example due to input of toxic loads from the sewer, or due to influent substrate shock load, is proposed. Considering that measurements of SS and XS concentrations are not available in real wastewater treatment plants, the S

Det här examensarbetet har till avsikt att fördjupa och aktualisera kunskapen om vilka skolvägsutredningsmetoder som är bäst lämpade för att klarlägga en förbättrad trafikmiljö för barn.

This study subsequently collects information from children via these surveys regarding their travel habits, the reason for their modes of transport and how they perceive different factors in the transport envir

Den svenska sexköpslagstiftningen är kontroversiell och har kritiserats för att sakna tydliga skyddsintressen och uppvisa bristande effektivitet. Även om lagstiftningen lett till minskad efterfrågan av sexuella tjänster i Sverige, kommer lagstiftningen inte åt de som istället köper sex utomlands i stater utan motsvarande lagstiftning. Kravet på dubbel straffbarhet hindrar lagföring i svensk domstoThe prohibition of purchase of sexual services under Swedish law is controversial and has been criticized for its lack of clear protection interests and defective efficiency. Although such legislation has reduced the demand for sexual services in Sweden, it does not apply when Swedish nationals purchase sexual services in states which do not have corresponding legislation. The double criminality r

How should we deal with city planning in a world that is rapidly turning urban, without destroying valuable nature assets along the way? The last decades are proof that the system we are using today is not up to the challenge. Therefore this thesis is showing a new approach to how comprehensive city planning can grow from nature based values and a deeper understanding of a city’s foundation. Toda

This thesis empirically investigates the question if US firm’s capital structures are stable over longer periods of time and which firm characteristics drive optimal leverage. The analysis is based on a Compustat panel data sample consisting of 2,900 US firms between 1985 and 2016. After analyzing the stability of firm’s capital structure via a “narrow band” and a “relative bucket approach” an err

Denna kandidatuppsats undersöker en direkt aktion mot brännvinsbrännerier som genomfördes i Karlshamn, november 1853. Den arbetande befolkningen i staden var vid denna tid mycket upprörda över det faktum att de lokala brännvinsbrännerierna fick fortsätta att köpa upp och bränna spannmål och potatis, trots den ständigt ökande bristen på livsmedel. Genom att tillämpa den brittiske historiken E.P. ThThis thesis aims to investigate a case of worker’s direct action against distilleries of hard liquor (brännvin) in the southern Swedish town of Karlshamn, November 1853. Many people were angry because the distilleries were allowed to keep on distilling grains and potatoes despite the constantly increasing shortage of basic foodstuffs. By applying English historian E.P. Thompson’s theory of “the mo

Recent research has shown that the solar energy has a potential impact on people1, which accounts for one of the most of the available renewable energy on earth. In this research, I decided to look deeply into the appliance of solar light systems, to make solar energy accessible fo

Huvudregeln i upphandlingsrätt är att upphandlingar ska annonseras. Detta grundar sig i principerna om att upphandlingar ska vara öppna för alla leverantörer att söka för att principerna om fri konkurrens och fri rörlighet av varor och tjänster i den inre marknaden ska säkerställas. Emellertid finns det undantag från denna huvudregel. Vid synnerlig brådska finns det möjlighet att frångå annonserinThe exception for extraordinary urgency is primarily evident through the strict interpretation by the European Court of Justice (ECJ). It's so strict that it has never been invoked in any of the Court's cases. The fundamental rule in procurement law mandates that tenders must be ad-vertised. This is rooted in the principles of open access for all suppliers with the intent to ensure free c

Objectives. To investigate the caries risk profiles in young adults and to compare the risk classification using the Public Dental Service (PDS) guidelines with a risk assessment program, the Cariogram. Materials and methods. All 19-year-old patients registered at eight public dental clinics were invited to participate (n = 1699). The study group who completed the baseline examination consisted of

Människokroppen förändras med ökad ålder. Rörelseapparaten, där skelett, leder och muskulatur ingår, påverkas av ökad ålder och där muskulaturen är mest ansatt. Ett vardagligt moment som att resa sig upp ifrån en stol kan därför bli svårt att utföra för äldre personer med en ökad risk för att falla. Den vanligaste olyckan i hemmet är fall. Var tredje person över 65-års ålder faller minst en gång The human body changes with increasing age. The locomotor system, where skeleton, joints and muscles are included, is affected with increased age where muscles are the most affected. A casual moment as rising from a chair will therefore be difficult to perform for older people and an increased risk of falling increases. The most common accident at home is falling accidents. Every third person ove

Conservation genomics is a rapidly growing subdiscipline of conservation biology that uses genome-wide information to inform management of biodiversity at all levels. Such efforts typically focus on species or systems of conservation interest, but rarely consider associated microbes. At least three major approaches have been used to study how microorganisms broadly contribute to conservation areas
