    Kandidatarbetet gick ut pĂ„ att göra gestaltningsförslag till tvĂ„ planteringar i en villatrĂ€dgĂ„rd som Ă€r belĂ€gen i Floda. Även om de tvĂ„ planteringarna hade skilda förutsĂ€ttningar skulle det finnas en samhörighet mellan de tvĂ„. Det fanns problem pĂ„ platsen i form av rĂ„djur och av den anledningen behövdes det vĂ€xter som inte Ă„ts upp av dem, det behövdes samt nĂ„gon metod för att hĂ„lla dem borta frĂ„n planteringarna. Litteratur studien undersökte vilka vĂ€xtalternativ det fanns nĂ€r rĂ„djur Ă€r ett problem i trĂ€dgĂ„rden. Den kunskapen tog jag med mig in i gestaltningsförslaget till de tvĂ„ planteringarna. En av planteringarna var befintlig och den andra skulle anlĂ€ggas pĂ„ en plats dĂ€r det förr var en stor kulle. Arbetet Ă€r uppbyggt i tre steg analys, koncept och gestaltningsförslag. En analys av platsen gav förstĂ„else för platsen och dess förutsĂ€ttningar, samt vilka förhĂ„llanden som rĂ„dde vid de tvĂ„ olika delarna av trĂ€dgĂ„rden, den befintliga planteringen och vid den som skulle anlĂ€ggas. I analysdelen fördes det en konversation med Ă€garna dĂ€r deras önskningar tydligt framkom. De viktigaste aspekterna frĂ„n deras sida var att det skulle vara planteringar med perenner och att det skulle vara relativt lĂ„g skötselnivĂ„, samt att fĂ€rgen lila var en viktig aspekt att fĂ„ med. Med kunskapen frĂ„n analysen och efter ett framtaget koncept utformade jag ett förslag till de olika planteringarna. Förslaget innehĂ„ller planteringsplaner, vĂ€xtlistor samt illustrationsplan. Resultatet visade sedan att designa planteringar som skall möta kundernas önskemĂ„l, vara hĂ„llbar, vara relativt lĂ„gt skötsel behov, ha en helhets bild med sammanhĂ€ngande tema i fĂ€rg och form samt inte bli förstörda av rĂ„djur, gĂ„r att göra pĂ„ mĂ„nga sĂ€tt. Det har mycket med personliga Ă„sikter och smak att göra och det blir i slutĂ€ndan detta som avgör, det finns mĂ„nga olika sĂ€tt att designa en plantering. Men det slutgiltiga resultatet visar hur man kan anvĂ€nda sig utav vĂ€xter med liknande fĂ€rg, med nĂ„gra inslag av kontrastfĂ€rger för att fĂ„ harmoniska, men Ă€ndĂ„ spĂ€nnande planteringar som möter kraven pĂ„ platsen samt Ă€garnas önskemĂ„l. Planteringarna Ă€r utformade helt efter kundernas önskemĂ„l av fĂ€rg och form och Ă€r vĂ€xtvalen Ă€r valda för att förhoppningsvis lĂ€mnas ifred utav rĂ„djuren, men om det gör det kan bara tiden avgöra

    HĂ€r i Sverige Ă€r det under stor del av Ă„ret mörkt och kallt, vilket försvĂ„rar för kĂ€nsligare grupper i samhĂ€llet att vistas utomhus under lĂ€ngre perioder. Detta gĂ€ller bland annat vĂ„ra Ă€ldre i samhĂ€llet. Vintern och mörkret kan i vissa fall leda till att en del personer inte kan ta sig ut om inte de fĂ„r hjĂ€lp, vilket i sin tur kan leda till att de inte gĂ„r ut och istĂ€llet spenderar nĂ€stan all sin tid inomhus. NĂ€rmiljön och omgivningen runt boenden spelar en större roll för att Ă€ldre personer skall kunna leva ett sĂ„ sjĂ€lvstĂ€ndigt liv som möjligt, med chansen till att sjĂ€lva avgöra vad de vill göra under sin dag och leva sĂ„ fritt som möjligt. Med anledning av detta kan tillgĂ„ng till och anvĂ€ndandet av vintertrĂ€dgĂ„rdar, det vill sĂ€ga övergĂ„ngszoner mellan inomhus och utomhus, vara betydelsefullt för mĂ„lgruppen Ă€ldre personer. I detta arbete sammanstĂ€lls vilka kvaliteter i vintertrĂ€dgĂ„rdar som Ă€r viktiga för att möta Ă€ldre personers behov. MĂ„lgruppen i arbetet Ă€r Ă€ldre personer, men jag har valt att göra en generell sammanstĂ€llning som kan fungera för alla Ă€ldre personer, oberoende Ă„lder, psykisk och fysisk hĂ€lsa. De boenden som undersöks i platsanalyserna samt i fokusgruppsintervjuerna Ă€r tvĂ„ olika seniorboenden (55+). Dessa boenden Ă€r Neptuna i VĂ€stra hamnen, Malmö och Bovieran pĂ„ Hönö. UpplĂ€gget av arbetet följer strukturen i QET, quality evaluation tool, men med en modifikation för att passa studiens syfte. Arbetet Ă€r uppbyggt i tre olika steg: Steg 1. inventering av evidensbaserade miljökvaliteter, i detta steg genomfördes en platsanalys av de valda platserna. Steg 2. Undersökning av miljökvaliteternas betydelse för de potentiella brukarna, detta steget genomfördes med fokusgruppintervjuer pĂ„ de tvĂ„ valda boendena. Steg 3. SammanstĂ€llning av steg 1 och steg 2, ta fram förslag pĂ„ konkreta Ă„tgĂ€rder och designförslag utifrĂ„n de nitton miljökvaliteterna sĂ„ miljön uppnĂ„r önskade behov. Det sista steget presenteras som Riktlinjer – viktiga miljökvaliteter i vintertrĂ€dgĂ„rdar. HĂ€r sammanstĂ€lls resultaten frĂ„n steg 1 och 2 genom att presentera vilka miljökvaliteter som Ă€r viktiga för mĂ„lgruppen i vintertrĂ€dgĂ„rdar.In Sweden, it is dark and cold for most of the year, which makes it harder for some of the more sensitive groups in society to stay outdoors for a longer period of time. This is especially true of the elderly in our society. Winter and darkness can in some cases lead to some people not being able to go outdoors unless they receive help, which in turn can cause them not to go out at all and instead spend almost all their time indoors. The surroundings play a bigger role in allowing the elderly to live as independently as possible, with the chance to decide for themselves what they want to do during the day and let them live as freely as possible. Because of this, access to and use of conservatories, i.e. transition areas between indoors and outdoors, be important for the elderly. In this work, the environmental qualities of winter gardens are examined and presented to meet the needs of the elderly. The target group at work is older people, but I have chosen to make a general compilation that can work for all older people, regardless of age, mental and physical health. The housing units that are examined in the site analyses and in the focus group interviews are two different senior housing units (55+). These accommodations are Neptuna in the Western Harbor, Malmö and Bovieran on Hönö. The composition of the study follows the structure of QET, the quality evaluation tool, but with a modification to fit the purpose of the study. The work is structured in three different steps: Step 1. inventory of evidence-based environmental qualities, in this step a landscape analysis of the selected sites was carried out. Step 2. Investigation of the importance of environmental qualities for potential users, this step was carried out with focus group interviews on the two selected residents. Step 3. Compilation of step 1 and step 2, prepare proposals for concrete measures and design proposals based on the nineteen environmental qualities so that the environment meets the desired needs. The final step is presented as Guidelines - important environmental qualities in winter gardens. Here, the results from step 1 and 2 are compiled by presenting the environmental qualities that are important for the target group in winter gardens

    We present a new 3-D shear-velocity model for the top 30 km of the crust in the wider Vienna Basin region based on surface waves extracted from ambient-noise cross-correlations. We use continuous seismic records of 63 broad-band stations of the AlpArray project to retrieve interstation Green’s functions from ambient-noise cross-correlations in the period range from 5 to 25 s. From these Green’s functions, we measure Rayleigh group traveltimes, utilizing all four components of the cross-correlation tensor, which are associated with Rayleigh waves (ZZ, RR, RZ and ZR), to exploit multiple measurements per station pair. A set of selection criteria is applied to ensure that we use high-quality recordings of fundamental Rayleigh modes. We regionalize the interstation group velocities in a 5 km × 5 km grid with an average path density of ∌20 paths per cell. From the resulting group-velocity maps, we extract local 1-D dispersion curves for each cell and invert all cells independently to retrieve the crustal shear-velocity structure of the study area. The resulting model provides a previously unachieved lateral resolution of seismic velocities in the region of ∌15 km. As major features, we image the Vienna Basin and Little Hungarian Plain as low-velocity anomalies, and the Bohemian Massif with high velocities. The edges of these features are marked with prominent velocity contrasts correlated with faults, such as the Alpine Front and Vienna Basin transfer fault system. The observed structures correlate well with surface geology, gravitational anomalies and the few known crystalline basement depths from boreholes. For depths larger than those reached by boreholes, the new model allows new insight into the complex structure of the Vienna Basin and surrounding areas, including deep low-velocity zones, which we image with previously unachieved detail. This model may be used in the future to interpret the deeper structures and tectonic evolution of the wider Vienna Basin region, evaluate natural resources, model wave propagation and improve earthquake locations, among others

    Arrival angles of teleseismic fundamental mode Rayleigh waves across the AlpArray

    The dense AlpArray network allows studying seismic wave propagation with high spatial resolution. Here we introduce an array approach to measure arrival angles of teleseismic Rayleigh waves. The approach combines the advantages of phase correlation as in the two-station method with array beamforming to obtain the phase-velocity vector. 20 earthquakes from the first two years of the AlpArray project are selected, and spatial patterns of arrival-angle deviations across the AlpArray are shown in maps, depending on period and earthquake location. The cause of these intriguing spatial patterns is discussed. A simple wave-propagation modelling example using an isolated anomaly and a Gaussian beam solution suggests that much of the complexity can be explained as a result of wave interference after passing a structural anomaly along the wave paths. This indicates that arrival-angle information constitutes useful additional information on the Earth structure, beyond what is currently used in inversions

    Charismatic Species as Indicators of Plastic Pollution in the RĂ­o de la Plata Estuarine Area, SW Atlantic

    Get PDF
    Marine plastic pollution is projected to increase globally in the next few decades.This holds true for South America where the number of species that interacts withplastics is increasing. In this study, we explore for the first time the potential of certaincharismatic species of marine turtles, mammals and seabirds as indicators of plasticpollution in the Río de la Plata (RdP), one of the largest and most important estuarineareas of the Southwest Atlantic. Through a revision of published studies integratedwith unpublished data, we summarize studies on the interaction of charismatic marinespecies with plastics in the region and evaluate their role as indicators of plasticpollution in the RdP based on aspects of their local ecology and key attributes (i.e.,biological/ecological, methodological, and conservation attributes) of indicator species.We found that at least 45 charismatic marine species interact ?whether by ingestionor entanglement? with plastics in the region. Eight of these species were selected aspotential indicators given their occurrence, probability of sampling and interaction withplastics in the RdP, namely: Chelonia mydas, Caretta caretta, Dermochelys coriacea,Pontoporia blainvillei, Arctocephalus australis, Otaria flavescens, Larus dominicanus,and Spheniscus magellanicus. The species shared some key attributes of indicatorspecies, e.g., they are relatively well studied, but differed in critical aspects such astheir home range and mobility. We discuss whether the species? attributes are strengthsor weaknesses according to the available knowledge on their ecology in the RdP, andpropose a multispecies indicator of plastic pollution given that those strengths andweaknesses can be compensated among species. Monitoring plastic pollution througha combination of species would enable a better understanding of plastic pollution in thisrelevant area.Fil: Gonzålez Carman, Victoria.

    Regulatory effects of simvastatin and apoJ on APP processing and amyloid-ÎČ clearance in blood-brain barrier endothelial cells

    Amyloid-ÎČ peptides (AÎČ) accumulate in cerebral capillaries indicating a central role of the blood-brain barrier (BBB) in the pathogenesis of Alzheimer\u27s disease (AD). Although a relationship between apolipoprotein-, cholesterol- and AÎČ metabolism is evident, the interconnecting mechanisms operating in brain capillary endothelial cells (BCEC) are poorly understood. ApoJ (clusterin) is present in HDL that regulates cholesterol metabolism which is disturbed in AD. ApoJ levels are increased in AD brains and in plasma of cerebral amyloid angiopathy (CAA) patients. ApoJ may bind, prevent fibrillization, and enhance clearance of AÎČ. We here define a connection of apoJ and cellular cholesterol homeostasis in amyloid precursor protein (APP) processing/AÎČ metabolism at the BBB. Silencing of apoJ in primary porcine (p)BCEC decreased intracellular APP and AÎČ oligomer levels while the addition of purified apoJ to pBCEC increased intracellular APP and enhanced AÎČ clearance across the pBCEC monolayer. Treatment of pBCEC with AÎČ(1-40) increased expression of apoJ and receptors involved in amyloid transport including lipoprotein receptor-related protein 1 [LRP1]. In accordance, cerebromicrovascular endothelial cells isolated from 3 x Tg AD mice showed elevated expression levels of apoJ and LRP1 as compared to Non-Tg animals. Treatment of pBCEC with HMGCoA-reductase inhibitor simvastatin markedly increased intracellular and secreted apoJ levels, in parallel increased secreted AÎČ oligomers and reduced AÎČ uptake and cell-associated AÎČ oligomers. Simvastatin effects on apoJ, APP processing, and LRP1 expression in BCEC were confirmed in the mouse model. We suggest a close and complex interaction of apoJ, cholesterol homeostasis, and APP/AÎČ processing and clearance at the BBB

    The junctional adhesion molecule JAM-C regulates polarized transendothelial migration of neutrophils in vivo

    No full text
    The migration of neutrophils into inflamed tissues is a fundamental component of innate immunity. A decisive step in this process is the polarized migration of blood neutrophils through endothelial cells (ECs) lining the venular lumen (transendothelial migration (TEM)) in a luminal-to-abluminal direction. By real-time confocal imaging, we found that neutrophils had disrupted polarized TEM ('hesitant' and 'reverse') in vivo. We noted these events in inflammation after ischemia-reperfusion injury, characterized by lower expression of junctional adhesion molecule C (JAM-C) at EC junctions, and they were enhanced by blockade or genetic deletion of JAM-C in ECs. Our results identify JAM-C as a key regulator of polarized neutrophil TEM in vivo and suggest that reverse TEM of neutrophils can contribute to the dissemination of systemic inflammation
