    Syftet med den hĂ€r kandidatuppsatsen Ă€r att undersöka om, och i sĂ„ fall hur, ge-staltningen av en bostadsgĂ„rd pĂ„verkar gĂ„rdens anvĂ€ndning. Uppsatsen utgĂ„r sĂ„ledes frĂ„n följande frĂ„gestĂ€llning: PĂ„verkar gestaltningen av en bostadsgĂ„rd anvĂ€ndningen av gĂ„rden, och vilka faktorer i utformningen Ă€r det i sĂ„ fall som har betydelse? Studien appliceras pĂ„ fyra bostadsgĂ„rdar i nyanlagda omrĂ„den i centrala Uppsala. En inventering genomfördes för att fĂ„ en uppfattning av gĂ„r-darnas utformning. Med det som grund gjordes en SWOT-analys som en summe-ring av gĂ„rdens eventuella styrkor, svagheter, möjligheter och hot. En enkĂ€tundersökning och samtal med de boende genomfördes, vilket gav en upp-fattning om de boendes anvĂ€ndning av gĂ„rden. Slutligen utfördes samtal med de gestaltande landskapsarkitekterna för att fĂ„ deras syn pĂ„ gestaltningsprocessen och den fĂ€rdiga gĂ„rden. VĂ„rt resultat visar att sju faktorer tycks pĂ„verka anvĂ€nd-ningen av gĂ„rdarna. Dessa Ă€r vegetationen, avskildheten, de sociala ytorna, bal-kongen, ljudnivĂ„n, lekplatsen och sollĂ€get. Resultatet tyder dock pĂ„ att gestaltningen av bostadsgĂ„rdar i nyanlagda omrĂ„den prĂ€glas av mĂ„nga begrĂ€ns-ningar, och dĂ„ framförallt att de byggs pĂ„ bjĂ€lklag. Det rĂ„der svĂ„ra förhĂ„llanden, med grunt jorddjup, vilket begrĂ€nsar möjligheten att fĂ„ upp stora vegetationsvo-lymer. SĂ„ Ă€ven om gestaltningen pĂ„verkar anvĂ€ndningen, begrĂ€nsas gestaltningen pĂ„tagligt av de rĂ„dande förhĂ„llandena, vilket i sin tur pĂ„verkar anvĂ€ndbarheten. I uppsatsens diskussionsavsnitt behandlas brukarnas preferenser och argument rörande gĂ„rdarnas olika delar.The aim of this Bachelor’s thesis is to investigate whether, and in that case, how the design affects the use of the housing estate. In order to specify the purpose this question at issue was used: Does the design of the housing estate affect the use, and in that case, what factors in the design affect the use? We started our project by choosing four housing estates which were as different from each other as possible. An inventory was made of each housing estate to get an idea of the design. By using the inventory we were able to make a SWOT analysis of the housing estates and look at potential strengths, weaknesses, opportunities and threats. A web survey was carried out followed by conversations with the resi-dents to get an idea of how they use their housing estate. Finally, we had conver-sations with the creative landscape architects to hear their point of views. The results show that seven factors in the design seem to affect the use of the housing estates. These are vegetation, privacy, social areas, balcony, noise, playground and sunny areas. However, the results indicate that the design of housing estates in the newly constructed areas are characterized by many restrictions, especially the fact that they are built on beam joists. Shallow soil means poor vegetation conditions. Thus, although the design markedly affects the use, it gets limited by the prevailing conditions, which in turn affects the use of the housing estate. The residents’ preferences and arguments relating to the different parts of the housing estates are processed in the discussion

    Uppsala Àr en stad som vÀxer och förtÀtas i snabb takt. Den höga exploateringen ger en ökad procent hÄrdgjord yta och fÀrre grönomrÄden. Detta leder till en större andel dagvatten som mÄste omhÀndertagas, dÄ den naturliga infiltrationen minskar. En god tillgÄng av natur och rekreation Àr viktigt för mÀnniskors vÀlbefinnande. NÀr andelen grönomrÄden minskar stÀlls det högre krav pÄ de som ÄterstÄr, för att uppfylla bÄde sociala, ekologiska och estetiska vÀrden. I detta arbete har ett gestaltningsförslag tagits fram av ett parkstrÄk i södra UllerÄker; ett planerat omrÄde i Uppsala med hög exploateringsgrad. Fokus i gestaltningen har varit att skapa ett parkstrÄk med en integrerad dagvattenhantering som samtidigt innehÄller ytor för vistelse och fungerar som en spridningsvÀg för hotade arter i omrÄdet. Den största utmaningen i gestaltningsarbetet har varit att rymma dessa funktioner pÄ en begrÀnsad yta. Arbetet Àr framtaget med trivalent design som hjÀlpmedel, dÀr en balans mellan sociala, ekologiska och estetiska vÀrden som utgÄngspunkt. Genom en tolkning av trivalent design formulerades frÄgor som anvÀnts under hela arbetet för att sÀkerstÀlla att alla tre vÀrden Äterfinns i gestaltningen. Gestaltningsförslagets utformning bygger pÄ ett koncept som bestÄr av tre delar; stark identitet, grön lÀnk och möten. DÀr stark identitet syftar till att skapa ett sammanhÀngande strÄk med en tydlig orienterbarhet, uppnÄs detta genom att lÄta Cinnoberbaggens röda fÀrg Äterkomma pÄ möbler och utrustning lÀngs hela strÄket. ParkstrÄket ska Àven fungera som en grön lÀnk mellan naturomrÄdena i öster och vÀster. Genom att bevara och plantera ny vegetation knutet till hotade arter i omrÄdet möjliggörs en spridningsvÀg. Möten stÄr för mötet mellan natur och stad dÀr parkstrÄket ska fungera som en brygga mellan dem. Det syftar Àven till att frÀmja möten mellan mÀnniskor genom att möjliggöra för spontan vistelse och aktivitet.Uppsala is a city that rapidly grows and densifies. The high exploitation results in a decreased percentage of green areas that can infiltrate water. This leads to a larger amount of stormwater to manage. A good access to nature and recreation is important for people's wellbeing. When the green spaces decreases, it require higher demands on those who remain to fulfill both; social, ecological and aesthetic values. This master thesis is presenting a design proposal of a park in southern UllerÄker; an area in Uppsala planned to be densified. The focus of the design has been to create a park with integrated stormwater management, that contains areas for social activity and that serves as an ecological pathway for endangered species in the local area. The biggest challenge in the design has been to merge these aspects together in to a limited area. Trivalent design was used as a tool to develop this master thesis, where a balance between social, ecological and aesthetic values is important. Through an interpretation of trivalent design, questions were formulated to ensure that all three values can be found in the design. The design of the proposal is based on a concept consisting three parts; strong identity, green link and meeting points. Where strong identity aims to create a coherent path with clear orientation. This is achieved by letting furniture and equipment have a red color, inspired by the Cinnoberbagge, an endangered beetle which can be found in the UllerÄkers area. The park will also serve as an ecological corridor between the green areas in east and west. This is accomplished by preserving and planting new vegetation linked to threatened species in the area. Meeting points represent the meeting between nature and the city where the park will function as a bridge between them. It also aims to encourage spontaneous social activity between people

    Mutations in \u3ci\u3eDMRT3\u3c/i\u3e Affect Locomotion in Horses and Spinal Circuit Function in Mice

    Locomotion in mammals relies on a central pattern-generating circuitry of spinal interneurons established during development that coordinates limb movement. These networks produce left–right alternation of limbs as well as coordinated activation of flexor and extensor muscles. Here we show that a premature stop codon in the DMRT3 gene has a major effect on the pattern of locomotion in horses. The mutation is permissive for the ability to perform alternate gaits and has a favorable effect on harness racing performance. Examination of wild-type and Dmrt3-null mice demonstrates that Dmrt3 is expressed in the dI6 subdivision of spinal cord neurons, takes part in neuronal specification within this subdivision, and is critical for the normal development of a coordinated locomotor network controlling limb movements. Our discovery positions Dmrt3 in a pivotal role for configuring the spinal circuits controlling stride in vertebrates. The DMRT3 mutation has had a major effect on the diversification of the domestic horse, as the altered gait characteristics of a number of breeds apparently require this mutation

    Lithocholic Acid Is an Eph-ephrin Ligand Interfering with Eph-kinase Activation

    Eph-ephrin system plays a central role in a large variety of human cancers. In fact, alterated expression and/or de-regulated function of Eph-ephrin system promotes tumorigenesis and development of a more aggressive and metastatic tumour phenotype. In particular EphA2 upregulation is correlated with tumour stage and progression and the expression of EphA2 in non-trasformed cells induces malignant transformation and confers tumorigenic potential. Based on these evidences our aim was to identify small molecules able to modulate EphA2-ephrinA1 activity through an ELISA-based binding screening. We identified lithocholic acid (LCA) as a competitive and reversible ligand inhibiting EphA2-ephrinA1 interaction (Ki = 49 ”M). Since each ephrin binds many Eph receptors, also LCA does not discriminate between different Eph-ephrin binding suggesting an interaction with a highly conserved region of Eph receptor family. Structurally related bile acids neither inhibited Eph-ephrin binding nor affected Eph phosphorylation. Conversely, LCA inhibited EphA2 phosphorylation induced by ephrinA1-Fc in PC3 and HT29 human prostate and colon adenocarcinoma cell lines (IC50 = 48 and 66 ”M, respectively) without affecting cell viability or other receptor tyrosine-kinase (EGFR, VEGFR, IGFR1ÎČ, IRKÎČ) activity. LCA did not inhibit the enzymatic kinase activity of EphA2 at 100 ”M (LANCE method) confirming to target the Eph-ephrin protein-protein interaction. Finally, LCA inhibited cell rounding and retraction induced by EphA2 activation in PC3 cells. In conclusion, our findings identified a hit compound useful for the development of molecules targeting ephrin system. Moreover, as ephrin signalling is a key player in the intestinal cell renewal, our work could provide an interesting starting point for further investigations about the role of LCA in the intestinal homeostasis

    Internationellt talas det ofta om den nordiska modellen – en modell som sammanlĂ€nkar de nordiska lĂ€nderna och dess vĂ€lfĂ€rdssystem. LĂ€nderna har dock valt att arrangera arbetsmarknadspolitiken pĂ„ olika sĂ€tt. Arbetsförmedling och andra typer av arbetsmarknadsĂ„tgĂ€rder görs pĂ„ olika sĂ€tt av olika aktörer i de olika lĂ€nderna. Alla lĂ€nder brottas dock med samma utmaningar kring arbetslöshet och utanförskap. Syftet med denna rapport frĂ„n Oxford Research Ă€r att jĂ€mföra de olika system som finns för att styra arbetsmarknadspolitiken i Norden för att lĂ€nderna dĂ€rmed ska kunna lĂ€ra sig av varandra. Rapporten granskar de reformer som gjorts sedan 2000 för att utröna vad som fĂ„tt effekt. Rapporten konkluderar med rekommendationer kring bland annat detaljstyrning, ekonomiska incitament som styrmedel, privata aktörer, reformtakten i Norden samt kommunernas roll inom arbetsmarknadspolitiken

    Locomotion in mammals relies on a central pattern-generating circuitry of spinal interneurons established during development that coordinates limb movement(1). These networks produce left–right alternation of limbs as well as coordinated activation of flexor and extensor muscles(2). Here we show that a premature stop codon in the DMRT3 gene has a major effect on the pattern of locomotion in horses. The mutation is permissive for the ability to perform alternate gaits and has a favourable effect on harness racing performance. Examination of wild-type and Dmrt3-null mice demonstrates that Dmrt3 is expressed in the dI6 subdivision of spinal cord neurons, takes part in neuronal specification within this subdivision, and is critical for the normal development of a coordinated locomotor network controlling limb movements.
