Why does trehalose not improve autophagy in the SOD1G93A transgenic mouse model of familial ALS?
Amyotrophic lateral sclerosis is one of the major neurodegenerative diseases, causing an ascending paralysis that usually kills the patient within a few years from disease onset. The motor neurons show aggregates of proteins which in approximately 20 % of cases of the familial form contain mutated SOD1 protein.
Trehalose is a disaccharide which has been shown to reduce protein aggregation and increase viability in cell models and alleviate symptoms in animal models of several neurodegenerative diseases associated with protein aggregation. When given orally to the SOD1G93A mouse model of ALS, trehalose failed to slow down the disease progression, which has led to questions about the uptake and distribution of the molecule in this mouse strain.
The aim of this study was to investigate whether significant levels of trehalose REACH the central nervous system of the SOD1G93A mouse after oral administration. This was performed by a trehalose assay of the brain of trehalose treated animals. A glucose assay was optimised for use in small samples of brain lysate after the digestion of trehalose into glucose by trehalase, and the difference in glucose concentration before and after digestion represented the trehalose level.
DET HÄR ÄR OCKSÅ GRAFISK DESIGN - Ett bidrag till diskussionen om ornamentik, funktionalism och kvinnors marginalisering.
This thesis examines the relationship between the marginalization of ornamentation
during functionalist modernism and the effect it had on female graphic design practice.
By examining the historiography from a gender and feminist theory of history I
present a different way of interpreting, not only the history of graphic design but also
the concept of graphic design. This thesis does not REACH a conclusive result, instead
it sets the foundation for further research and illustrates the opportunities that we as
graphic designers have to benefit contemporary graphic design by critically reviewing
and redefining our history through a diverse historiography..
Maskinskydd på rullriktverk
ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s REACH.
Vertikalhoppet uppvisar högre sensitivitet i jämförelse med horisontalhoppet och trippelhoppet - 7 månader efter ACL-rekonstruktion
Syfte och frågeställningarHuvudsyftet med denna studie var att se om ett vertikalhopp eller ett trippelhopp uppvisade större känslighet att identifiera skillnader mellan opererat och icke-opererat ben i jämförelse med ett horisontalhopp hos individer som genomgått främre korsbands(ACL)-rekonstruktion.Studien syftade även till att undersöka om individens kön påverkade resultatet och om prestationen på de olika hoppen hade ett samband med isokinetisk benstyrka respektive det knäspecifika instrumentet KOOS, The Knee injury and Osteoarthritis Outcome Score.Metod17 försökspersoner, 9 män och 8 kvinnor (medelålder 28 år) deltog i studien. De hade alla genomgått primär unilateral ACL-rekonstruktion i genomsnitt 7 månader tidigare. Vid ett och samma mättillfälle utfördes ett isokinetiskt styrketest samt tre funktionella hopp: vertikalhopp (?Jump and REACH?), trippelhopp samt horisontalhopp. KOOS fylldes i av försökspersonerna runt samma tidpunkt (nätbaserat frågeformulär för utvärdering av patientens upplevelse av sitt knä och knärelaterade besvär).ResultatVertikalhoppet uppvisade en högre sensitivitet i jämförelse med horisontalhoppet vid test 7 månader efter ACL-rekonstruktion.Gällande de absoluta värdena (opererat ben) uppvisade både vertikalhoppet som trippelhoppet ett statistiskt samband med explosiv quadricepsstyrka (240grader/sekund), r=0,75 respektive r=0,73.Inget samband kunde ses mellan hopp och resultatet på KOOS.Inga könsskillnader hittades.SlutsatsResultaten visar att vertikalhoppet är ett mer sensitivt test för att identifiera funktionella nedsättningar i ACL-rekonstruerat knä i jämförelse med horisontalhoppet som ofta används som ?gold standard? i forskning och i den kliniska vardagen.En enkel och billig testmetod för vertikalhoppet, ?Jump and REACH? som användes i denna studie visar liknande resultat på sensitiviteten i jämförelse med datoriserade mätmetoder som är dyra och ofta inte tillgängliga i sjukgymnastens kliniska vardag..
Styrmekanismers funktion i relationsbyggande: En studie av ett relationsnätverk i verkstadsindustrin
The aim of this study has been to examine the role of control mechanisms when it comes to building relationships in a small business network. In order to REACH this goal, we have performed a case study of a Swedish supplier of machines to the engineering industry, which acts as the exclusive representative of a foreign manufacturer on the Swedish market. Main results: A number of control mechanisms, both formal and informal, could be identified in the network. Their specific use, as well as relative importance differ between different actors in the network. In general, the importance of formal control mechanisms decreases as the relationship evolves over time and the importance of informal ones, mainly trust, increases in a corresponding manner..
Säkerhetsbrytare för Gräsklippare
This thesis describes teh solution of two problems regarding safety on powered lawnmowers; protectning the users from injury when using the lawnmower in slopes, and when cleaning the cutting blade.The task was carried out through initial studies on a representative lawnmower. A generation of ideas followed with an evaluation to select the best solution. The winning concept was further developed to REACH acceptable performance. The word resulted in a functioning prototype utilising an original way of detecting inclinations without incorrect signals. It c an serve as a platform for further development into a product.The work gives insightful experience of solving real-world problems, and especially to deal with situations where several variables and their effects are unknownPlease note that several parts of the work are confidential, and have therefore been removed from the thesis..

Anaerob nedbrytning av TNT : Ett bioreaktorförsök på Vingåkersverken
A bioslurry reactor was built for the bioremediation of TNT contaminated waste from the demilitarization industry. The field test was conducted at Vingåkersverken in Vingåker, Sweden, to see if results from laboratory studies could be repeated in a full scale reactor. The goal of the project was to optimize the reactor to such a degree that it could be used to handle the waste produced at Vingåkersverken and also that this technique could be applied for remediation of contaminated soils. Unfortunately the samples taken during the full scale field test were destroyed by the shipping company and no analysis was possible. A later attempt by the Biorex research group has also been unsuccessful to reduce the amount of TNT using the bioreactor.

Theborrowers and the personnel are quite satisfied with the work and are only pointing out a fewviews on changes. The politicians mean that the aim of the extension work of the library ison one hand to give service to certain more or less neglected groups and on the other handto REACH new book readers..
Energivinst vid hybridisering av hydrauliskt system
Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A REACH stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.
Energikartläggning av Fridhemsskolan 16:2
