Dalby Söderskog är belägen tio kilometer öster om Lund och har varit nationalpark sedan 1918. Växtligheten består av ädellövträd samt en rik vårflora av bland annat vitoch gulsippor och skånsk nunneört. Sommaren 1921 utfördes en taxering av skogen och en karta upprättades (figur 1). Kartan visar Söderskogens utbredning samt varje träd i densamma. Arbetet grundar sig på just denna karta men tar äve
Popular Abstract in Swedish Membranteknik är en separationsteknik där stora partiklar skiljs av från mindre partiklar m.h.a. ett membranfilter. I min forskning har jag tittat på hur membranfiltrering kan användas inom bioteknikindustrin. Jag har tittat på hur mjölksyra kan renas upp från en lösning av jäst "vetemjölsvälling" samt hur första steget i uppreningen av protein A från en industriellt prMembrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. However, one drawback is that these liquids are often very complex, which is a disadvantage when using membrane technology as it makes the
A key virulence trait of pathogenic bacteria is the ability to bind to receptors on mucosal cells. Here the potential glycosphingolipid receptors of enterohemorrhagic Escherichia coli were examined by binding of S-35-labeled bacteria to glycosphingolipids on thin-layer chromatograms. Thereby a selective interaction with two nonacid glycosphingolipids of cat small intestinal epithelium was found. T
Purpose Biofilm infections have a major role in implants or devices placed in the human body. As part of the endourological development, a great variety of foreign bodies have been designed, and with the increasing number of biomaterial devices used in urology, biofilm formation and device infection is an issue of growing importance. Methods A literature search was performed in the Medline databas
When fruits ripen, microbial communities start a fierce competition for the freely available fruit sugars. Three yeast lineages, including baker's yeast Saccharomyces cerevisiae, have independently developed the metabolic activity to convert simple sugars into ethanol even under fully aerobic conditions. This fermentation capacity, named Crabtree effect, reduces the cell-biomass production but pro
For years tools and techniques such as Brainstorming, Mind-Maps and Rich Pictures have been used in both academic and professional practices to assist people with making sense of complex problem spaces. These tools have their supporters and in many cases their uses can be argued to be interchangeable. Seldom however have they been systematically applied in combination in theory or practice. Even t
Mutations in the PTEN gene are associated with a broad spectrum of disorders, including Cowden syndrome (CS), Bannayan-Riley-Ruvalcaba syndrome, Proteus syndrome, and Lhermitte-Duclos disease. In addition, PTEN mutations have been described in a few patients with autism spectrum disorders (ASDs) and macrocephaly. In this study, we screened the PTEN gene for mutations and deletions in 88 patients w
AimsMyoepithelial tumours of soft tissue are rare lesions with a broad morphological and clinical spectrum. Previous studies have found EWSR1 rearrangements in approximately half of all cases and PBX1, ZNF44 and POU5F1 have been identified as recurrent fusion partners. In bone, only a small number of myoepithelial tumours have been described. We investigated an intraosseous myoepithelioma of the s
Rabbit tibialis anterior (TA) and extensor digitorum longus (EDL) muscles are used extensively in studies of stimulation-induced fibre type transformation, but the proportions and sizes of the 2 main fibre types, and the way in which they are distributed within the muscles, have never been described in any detail. In this study, transverse sections were processed by enzyme histochemical and immuno
Plast ger upphov till stora mängder avfall i världen som riskerar att hamna i naturen. Fenomenet med mikroplastpartiklar från konventionell plast beror på att det mesta av den fossilbaserade plasten inte bryts ner biologiskt utan endast vittrar sönder till mindre delar. Detta examensarbete försöker ta reda på om biologiskt nedbrytbar plast kan lösa detta problem. Genom en litteraturstudie undersökThe purpose of this essay is to investigate if biodegradable plastics can solve the plastic littering problem. The essay discusses how bio-plastics is defined in society by different stakeholders such as the bio-plastics industry, science and municipal waste companies. A literature study on the subject of degradation of polymers have been made to find information on how different types of plastic
