This paper reports a method to produce a solvent-free extract from green tea leaves with high content of catechins and low content of caffeine, in two steps and using only "green" solvents. The method is based on the pressurized liquid extraction (PLE) of the green tea leaves using ethyl lactate as solvent, followed by a selective precipitation procedure using the supercritical carbon dioxide (SCC
A major bottleneck in high-throughput protein production is the validation step, which is why parallel and automated sample processing methods are highly desirable. Also, a miniaturized sample preparation format is preferred, as the reduction of reagent volumes significantly decreases the analysis cost per sample. We have developed an automated and miniaturized protein sequence verification protoc
Africa is largely influenced by fires, which play an important ecological role influencing the distribution and structure of grassland, savanna and forest biomes. Here vegetation strongly interacts with climate and other environmental factors, such as herbivory and humans. Fire-enabled Dynamic Global Vegetation Models (DGVMs) display high uncertainty in predicting the distribution of current tropi
The concentrations of cartilage proteoglycan (aggrecan), stromelysin-1, tissue inhibitor of metalloproteinases-1 (TIMP-1) and procollagen II C-propeptide in knee joint fluid and the levels of aggrecan, hyaluronan and keratan sulfate in serum were measured before and after exercise in 33 healthy athletes. The samples before exercise were obtained after 24 h rest from running or soccer and the sampl
Populärvetenskaplig sammanfattning: AB Klippans Läderfabrik var under sina verksamma år en av de största arbetsgivarna i området. Ett flertal giftiga ämnen användes i verksamheten, främst krom men även formalin och under en kort period arsenik. Fabrikstomten kom med tiden att förorenas. Stora delar av fabriken brann ned år 1917 och röken från branden sträckte sig in över ett intilliggande villaomrDuring environmental investigations at the polluted Klippan Leather Factory, elevated levels of arsenic were detected in the adjacent residential area. The arsenic is believed to have originated from a fire in the leather factory in 1917, when a plume of smoke covered the residential area and deposited arsenic as fallout. Investigations showed that the pollution was located in the topsoil, and dur
Histamine is known to be present in ovarian tissue and may play a role in the ovulation process. The effect of histamine on the follicular smooth musculature was investigated using strips from the protruding part of mature bovine follicles, mounted in vitro for registration of isometric motor activity. Histamine contracted the preparation in a concentration-dependent manner. The response was inhib
Questions: How does the number of species in a community affect the level of genetic diversity of its constituent species? What is the relation between competitive interactions and the spatial distribution of genetic variation? When spatially structured, how is the genetic differentiation among subpopulations affected by competition and size of the community? Model features and key assumptions: A
Acoustophoresis is a method to manipulate and move cells or particles suspended in a medium using acoustic waves. The speed of the acoustophoretic motion depends on the cells' acoustic mobility, i.e. their size, density and compressibility relative to the medium. Differences in acoustic mobility can be used to separate particles from each other. Separation is an important tool within biomedica
Uppsatsens övergripande syfte är att utreda såväl innebörden som omfattningen av Migrationsverkets och migrationsdomstolarnas utredningsansvar i asylärenden/ mål enligt 23 § FL respektive 8 § FPL. För att kunna ge en tillfredsställande bild av utredningsansvaret studeras dessutom, om än mer kortfattat, bevisreglerna i asylärenden/mål. Uppsatsen ger inledningsvis en introduktion till regleringen The overall purpose of the thesis is to investigate the meaning and scope of the Swedish Migration Agency's and the Migration Courts' investigative responsibility in asylum cases /cases according to § 23 FL and § 8 FPL. In order to be able to give a satisfying picture of the investigative responsibility, the rules of evidence in asylum cases /cases are also studied, but more briefly. The
The overall purpose of this thesis is to investigate the feasibility of producing electrofuels from CO2 and H2 in connection to a CHP plant equipped with carbon capture technology. This is done by investigating the production of e-methane, e-methanol and e-kerosene from captured CO2 and H2 produced from electrolysis. Each of the processes is designed and analyzed in Aspen HYSYS. From this, the ene
While calls to reduce air travel have emerged in many high-income countries, Nepal, with only one international airport, is still striving to improve its air connectivity. In 2015, the government resumed its 1995 plan to build a second international airport near Nijgadh, a town in the southern plains. The project has since come under scrutiny from conservationists after plans emerged for extensive
I Sverige kom det första undantaget från turordningsreglerna 1994 med syftet att upprätthålla balansen mellan arbetstagarnas trygghet och verksamheternas behov av flexibilitet. Sedan 2001 är undantaget i turordningsreglerna begränsat till två personer och gäller för företag med högst tio anställda. År 2020 är tvåundantaget återigen uppe för diskussion om ändring i och med betänkandet SOU 2020:30, In Sweden the first exception concerning turn rules was accepted in 1994 with the purpose to maintain the balance between employment protection and the companies need for flexibility. Since 2001 the exception concerning turn rules is limited to two employees for organisations with at most ten employees. In the year of 2020 the exception within the turn rules is up for discussion once again hence t
Stora invandringsflöden till Sverige under många år har gjort Sverige till ett av de länder som har störst andel invandrare per yta. En av de viktigaste frågorna är huruvida invandrare kommer in på arbetsmarknaden och vad det i så fall har för följder på svenskföddas arbetsmarknadsutfall. Syftet med denna uppsats är att undersöka hur invandringen påverkar den svenska arbetsmarknaden då det gälle
In this master´s thesis I seek to explore the concept of restorative justice, an ideological approach to justice which aims to repair the harm caused by crime through means of communication, cooperation, participation and restoration. By involving all parties affected by crime, restorative justice seeks to address crime through empowering victims, increasing community cohesion and making offenders

Seriefelet i Forsmarks kärnkraftverk den 30 maj 2013 har uppmärksammat behovet av utredning kring effekterna av fasavbrott på transformatorers primärsida när sekundärsidan är lastad med olika typer av last. I Forsmark spänningssattes de bortfallna faserna bakvägen via kombinationen av transformatorer och lastobjekt i systemet så väl att underspänningsskydden inte kunde detektera felet. Reservkraft
The concentration of soluble HLA class I (sHLA-I) was measured by ELISA in serum samples from 30 well-characterised SLE patients at high and low disease activity states and from 100 healthy controls. HLA-A allotypes in the patients were analysed by a PCR-based typing technique. A higher level of sHLA-I was found in SLE patient sera both at high and low disease activity than in controls (P< 0.001).
In northern Sweden, Empetrum hermaphroditum Hagerup dominates the ground layer vegetation in post fire successions by suppressing other plant species. Previous studies suggest that this negative effect by E. hermaphroditum may be explained, at least in part, by the release of phenolic compounds, particularly batatasin-III, from foliage to soil. In this pilot study, we evaluated the effect of batat
A gene encoding a lipolytic enzyme amplified from the alkaliphilic bacterium Bacillus halodurans LBB2 was cloned into the pPICZ alpha B vector and integrated into the genome of the protease deficient yeast strain Pichia pastoris SMD1168H. This previously undescribed enzyme was produced in active form, and cloning in frame with the Saccharomyces cerevisiae secretion signal (alpha-factor) enabled ex
