Anaerobic Treatment of Agricultural Residues and Wastewater - Application of High-Rate Reactors

The production of methane via anaerobic digestion of agricultural residues and industrial wastewater would benefit society by providing a clean fuel from renewable feedstocks. This would reduce the use of fossil-fuel-derived energy and reduce environmental impact, including global warming and pollution. Limitation of carbon dioxide and other emissions through emission regulations, carbon taxes, an

Efter stormen. En sociologisk undersökning av skogsägarfamiljer

After the storm. A sociological analysis of families owning forest properties. A Book By Sellerberg publiched by Bokbox, March 2011 "Has it been windy?", someone asks a forest owner in March 2005. In January practically all of his forest was annihilated. A storm rolled by with winds as strong as 46 metres per second. The forest owners in Kronoberg county were particularly badly hit by the disaste

Management of Information Systems Outsourcing: Challenges and Lessons Learned

To be successful in Information Systems (IS) outsourcing the necessity of better management practices has been pointed out.This research contributes to the knowledge base on management of IS outsourcing by addressing management of ISoutsourcing relationships. The research describes two cases of IS outsourcing relationships that differ in type of activityoutsourced, IS development versus IS mainten

The public sphere: Linking the media and civic cultures

The perspective of the public sphere, despite its utility, has some gaps. Not least is its lack of sociological anchoring in the everyday lives and experiences of citizens. The text argues that we can illuminate the media's role in promoting or hindering participation in the public sphere by making use of the six-dimensional framework of civic cultures.

Integrated Chromatographic Systems for On-Line Bioprocess Monitoring Based on Microdialysis or Tangential Flow Filtration

Popular Abstract in Swedish För drygt tio år sedan startade ett forskningsprojekt mellan fyra avdelningar på Kemicentrum i Lund i syfte att ta fram en process för framställning av etanol ur snabbväxande energiskog. Etanol är ett miljövänligt alternativ till bensin som drivmedel för bilar och bussar, och redan idag körs ungefär 100 bussar i svenska städer på detta bränsle. Priset på drivmedelsetanoSystems for on-line monitoring of bioprocesses were developed, consisting of a membrane-based sampling unit, a liquid chromatographic (LC) separation step, and a detector. Two sampling units, a tangential flow filtration (TFF) module and a microdialysis probe, were characterised and evaluated for use in different types of bioprocesses. When using the TFF module, an additional sample clean-up step

Optimum data rate in cellular systems

The spectrum efficiency in a cellular radio system is affected by the data rates used in the system. High data rates may result in low spectrum efficiency if the frequency reuse is low. The spectrum efficiency may be enhanced by using adaptive modulation with carefully chosen data rates. We present an analytical method, based on a lower bound on the BER, for finding the best data rates. The method

Global Engagement, Complex Tasks, and the Distribution of Occupational Employment

Building on a framework introduced by Chaney and Ossa (2013), we construct a task-based model of the firm’s choice of occupational inputs to examine how that choice varies with greater global engagement. We depart from Chaney and Ossa by assuming that more complex tasks are more costly to complete. Within the structure of our model, firms skew employment toward occupations engaged in more complex
