ABSTRACT: BACKGROUND: Two-step dilute acid hydrolysis of softwood, either as a stand-alone process or as pretreatment before enzymatic hydrolysis, is considered to result in higher sugar yields than one-step acid hydrolysis. However, this requires removal of the liquid between the two steps. In an industrial process, filtration and washing of the material between the two steps is difficult, as it
Background: When scaling up lignocellulose-based ethanol production, the desire to increase the final ethanol titer after fermentation can introduce problems. A high concentration of water-insoluble solids (WIS) is needed in the enzymatic hydrolysis step, resulting in increased viscosity, which can cause mass and heat transfer problems because of poor mixing of the material. In the present study,
This article is a way to try to concretize the so-called new economy based on a couple of concrete expressions. The concepts of cultural heritage and consumption are used to describe and analyse some specific service operations in a couple of Swedish retailers. In both are the products manufactured, in one case, stone-baked sourdough bread and in the other handmade chocolates with reference to tra
The purpose of the project has been to investigate how people dwell and furnish in recently build apartments. The project consists of a dwelling survey where 14 tenants in four different types of apartments, architects, realtors and an availability expert are interviewed to give their view on how Swedish regulations regarding housing corresponds to how people live, and want to live. The project co
I dagens samhälle görs IT investeringar i alla tänkbara verksamheter. Om investeringen lyckas eller inte beror bland annat på förståelsen av vilka delar av verksamheten som kommer att påverkas samt hur de kommer att påverkas. Uppsatsen behandlar hur nyttovärdering av IT-investeringar görs i verkligheten i jämförelse med vad som nämns i litteraturen. Syftet med uppsatsen är att få grepp om olika as
A general introduction to the use of feed-back artificial neural networks (ANN) for obtaining good approximate solutions to combinatorial optimization problems is given, assuming no previous knowledge in the field. In particular we emphasize a novel neural mapping technique which efficiently reduces the solution space. This approach maps the problems onto Potts glass rather than spin glass models.
Vatten är en naturresurs som vi kanske tar lite för mycket för givet i vårt land. Grundvattenforskaren charlotte Sparrenbom menar att skyddet av den kanske viktigaste naturresursen för vår överlevnad är kraftigt eftersatt. hon vill väcka till eftertanke om hur vårt fotavtryck ser ut för kommande generationer, och föreslå sätt att komma igång med bättre skydd av vårt vatten.
The article argues that the way Anabaptist history and theology is commonly narrated needs to be reshaped. A fundamental question is asked: Did women have positions of power in the early Anabaptist movement? Two points are considered: 1) How is power understood? and 2) On what premises can the history of Anabaptist women be written? These two points are put in relation to portraits of three women
Considerable efforts by leading experts and funds from around the world are put into restructuring the West Bank justice and security sector (JSS). This is an effort done in a highly contested environment, with an ongoing Israeli occupation and weak local trust in the Palestine Authority (PA). This article analyzes the understandings by local Palestinian non-government organizations and internatio
Artikeln undersöker en teologisk traktat skriven på 1570-talet av Jesper Marci, kyrkoherde i Vadstena, (handskriften T 147 i Linköpings stiftsbibliotek), riktad mot Hans Pauli Montanus, kaplan i Vadstena kloster, och dennes enligt Jesper Marci vidskepliga bruk av vigvatten under 1570-talet. Det svenska reformatoriska prästvigningsritualet och bakgrunden till det symboliska överlämnandet av en bib
