The use of commercial proteases, bromelain and Protex 30L for oil extraction/recovery of polyunsaturated fatty acids (PUFA) from Nile perch and salmon heads was evaluated. Four phases were obtained after hydrolysis, oily phase, emulsion, aqueous phase and sludge. An increase in water content during the hydrolysis resulted in a decrease in oil yield. Maximum oil yield was obtained when hydrolysis w

The effect of applied potential pulses on DNA functionalization (thiolated single stranded DNA) and hybridization processes has been monitored in-situ on gold surfaces using electrochemical quartz crystal microbalance with dissipation (EQCM-D). The applied potentials were chosen with respect to the potential of zero charge (E-pzc) of the gold surfaces: a positive potential to attract the negativel

A bi-enzymatic cascade consisting of a Baeyer-Villiger monooxygenase and an alcohol dehydrogenase (ADH) was designed in a convergent fashion to utilise two molar equivalents of cyclohexanone (CHO) and one equivalent of 1,6-hexanediol as a 'double-smart cosubstrate' to produce epsilon-caprolactone (ECL) with water as sole by-product. The convergent enzymatic cascade reaction reported herein, is per

Previous research on violence during the war in Bosnia and Herzegovina has resulted in a one-sided presentation of the phenomenon of “war violence.” Researchers have emphasized the importance of narratives in general but have not analyzed stories on war violence that were the product of interpersonal interaction and meaning-making activity. The aim of this article is to fill this knowledge gap by

In this study, we investigate structural transitions of tetraethylene glycol monohexadecyl ether (C16E4) in D2O as a function of shear flow and temperature. Via a combination of rheology, rheo-small-angle neutron scattering and rheo-small-angle light scattering, we probe the structural evolution of the system with respect to shear and temperature. Multi-lamellar vesicles, planar lamellae, and a sp

Response times to risky events have been seen to increase with the use of adaptive cruise control (ACC). It has been unclear whether driver experience with ACC mediates this increase. We compare driving in a cut-in event in a simulator both with and without system support, studying ACC as well as ACC with automatic steering. 31 participants were tested in a repeated-measures design, 10 novices and

Evidence for distinct human cancer stem cells (CSCs) remains contentious and the degree to which different cancer cells contribute to propagating malignancies in patients remains unexplored. In low- to intermediate-risk myelodysplastic syndromes (MDS), we establish the existence of rare multipotent MDS stem cells (MDS-SCs), and their hierarchical relationship to lineage-restricted MDS progenitors.

The recent loss of pollinating insects and out-crossing plants in agricultural landscapes has raised concern for the maintenance of ecosystem services. Wild bees have been shown to benefit from garden habitats in urban and suburban areas. We investigated the effects of distance from garden habitats on wild bees and seed set of a native out-crossing plant Campanula persicifolia, in intensively mana

Biological production of hydrogen sulfide (H2S) using sulfate-reducing bacteria (SRB) has important potential within environmental biotechnology. The aim of this work was to study the possibility of using SRB for the treatment of an acid mine drainage (AMD) at bench-scale. This process involved three stages: the optimization of H2S production through the utilization of total volatile fatty acids (

Some case reports have shown that patients suffering from obsessive-compulsive disorder can be effectively treated with anti-androgenic pharmacological agents with various modes of action. The most effective group of such agents is the long-acting analogues of the gonadotropin-releasing hormone. This investigation was undertaken in order to further elucidate the possibility of using such powerful

Phosphorylation of extracellular-signal-regulated kinase 1/2 (p-ERK 1/2) was investigated by immunohistochemistry at 30 min, 1 h, and 48 h after nerve transection in the sciatic nerve of healthy and diabetic [streptozotocin (STZ)-induced diabetes mellitus and BioBreeding (BB; i.e. DR.lyp/lyp or BBDP)] rats. Transection injury increased the intensity of p-ERK 1/2 in nerve stumps at all time points.

Popular Abstract in Swedish En omorganisation av det svenska Vägverket har medfört ett behov för dem att fungera som en professionell beställare enbart, utan utförande i egen regi. Det har naturligtvis också medfört en förändring i hur man hanterar upphandlingen av vägunderhåll. En väghållares främsta uppgift är att underhålla befintliga anläggningar och se till at de fungerar som avsett. Den näsA reorganization of the Swedish National Road Administration (SNRA) has urged a demand to work as a professional agency only, without any work by direct labor. This structure has enforced a change in how to handle the pavement maintenance and performance contracts are being promoted since they encourage product development and sustainability. Furthermore, SNRA desires to use the road network as a

In recent decades we have witnessed a proliferation of new kinds of retail space. Retail space has cropped up just about everywhere in the urban landscape, at libraries, workplaces, churches and museums. In short, retail is becoming a more and more manifest part of the public domain. The traditional spaces of retail such as city centres and outlying shopping malls are either increasing in size or

Popular Abstract in Swedish "Män födda 1914" är en studie som påbörjades 1982 för att studera hjärt- och kärlsjukdomar. Studien bedrivs vid Institutionen för samhällsmedicin vid Universitetssjukhuset MAS. Alla män, födda jämn månad 1914 och bosatta i Malmö, inbjöds att deltaga. Totalt inbjöds 621 män, då 68 år gamla, och av dessa deltog 500. Då man jämförde deltagare med icke-deltagare kunde man k"Men born in 1914" is a prospective cohort study on the epidemiology of cardiovascular disease. The study is run by the Department of Community Medicine, Lund University, Malmö. Five hundred men participated in the study when it started with a baseline examination in 1982/83. The men were then 68 years old. The psychological part of the study included tests of cognitive function and the serial Col

This thesis investigates advanced Swedish students’ development of three grammatical phenomena: subject-verb concord, prepositions and article use in compositions and translations. In order to describe the students’ development of these categories, actual errors are related to potential errors forming so called ‘error scores’. When the error score for the first test opportunity is compared with th

Combining the strengths of an advanced mathematical model of human physiology and a thermal manikin is a new paradigm for simulating thermal behaviour of humans. However, the forerunners of such adaptive manikins showed some substantial limitations. This project aimed to determine the opportunities and constraints of the existing thermal manikins when dynamically controlled by a mathematical model

In 1998 renewable energy sources supplied 56 ± 10 exajoules,or about 14 percent of world primary energy consumption. Thesupply was dominated by traditional biomass (38 ± 10 exajoules a year. Other major contributions came from large hydropower (9 exajoules a year) and from modern biomass (7 exajoules). The contribution of all other renewables — small hydropower, geothermal, wind, solar, and marine

The short-chain fatty acids (SCFA) formed from colonic fermentation of indigestible carbohydrates have been suggested to exert different physiological effects. In this thesis the fermentability and SCFA produced from various indigestible carbohydrates in the hind-gut were investigated using balance experiments in rats. In the case of propionate, experiments were also performed to evaluate possibl

This book commemorates the 65th birthday of Karl Johan Åström, who is professor in Automatic Control at Lund Institute of Technology. Karl Johan Åström is one of the leading researchers of the world in automatic control. The contributions are chosen to illustrate some of the areas where Karl Johan Åström has been active in his research. The idea of the papers is also to point out new directions wi
