Lina och Ronna, strax utanför Södertälje i Stockholm, har i en undersökning påvisat hög kriminalitet och en otrygg befolkning. Områdena har trots sitt knappa avstånd stora socioekonomiska olikheter. Min ambition med projektet är att förena stadsdelarna på en bondgårdsinspirerad social mötesplats belägen på en åker strax utanför staden. Genom allt från en föreläsningssal i en lada, ett ekologiskt café, en restaurang och en uteservering i en silo, till växthus och odlingsytor samt en inbjudande marknadsplats som byggs upp av invånarna själva, engageras befolkningen till att bli mer självförsörjande, att börja odla och att finna en gemenskap i odlingen som aktivitet. De traditionella bondgårdshusen som återfinns på platsen för tanken tillbaka i tiden och ut mot landsbygden. Mötesplatsen ligger i anknytning till kolonilotter på åkern som dels bidrar till det visuella lärandet av att besöka platsen, men som också tillåts få sälja sina varor där. Slutligen är förslaget ett initiativ att se på varandra bortom social och ekonomisk status som jämlika. Ett sätt att öppna ögonen för varandra och inse att vi har mer gemensamt än vad vi tror, men också att det finns otroligt mycket som vi fortfarande kan lära av varandra. / Lina and Ronna, outside of Södertälje, Stockholm, have demonstrated high levels of criminality and insecurity in studies. The regions have, despite minimal distance, great differences in socio-economic standards. My ambition with this project is to unite the districts on a farm-inspired meeting place located outside the town. With everything from a lecture hall in a barn, an organic café, a restaurant and outdoor seating in a silo, to greenhouses and farming fields as well as an inviting marketplace built by the inhabitants, the visitors are encouraged to become more self-sufficient, cultivate, and build community via cultivating. The traditional farmhouses found on the location brings the visitor back in time and towards the countryside. The meeting place is closely connected with allotments, which partly contributes to the visual learning of visiting the place, but which also allows the cultivators to sell fresh produce at the market. Lastly, the proposition is an initiative to invite people to see beyond social and economical status and see each other as equals. A way of opening our eyes up to each other, discovering that we have more in common than previously thought, and realising there is much we have yet to learn from each other.

With the aim of designing an infrasound-integrated technology which can enhance the algae drying performance, this thesis provided the theoretical possibility of using infrasound as an algae dehydration technology. To test the relation between algae drying speed and other three parameters namely sound frequency, sound pressure and sample mass, four major experimental groups including initial experiments and core experiments with fifteen sub-experimental groups are designed. Results of the experiments shows expected accordance with the theoretical inferences of infrasound being an algae drying technology. Experiment steps and specifications are presented as the research methodology. A real system with the drying capacity of 2 ton fresh algae per day are designed based on the experimental calculations and results. Several revisions including air circulation and infrasound resonance are made when scaling up the research from experimental level up to industrial level. Other specifications of the real system design follow the experiment results with regard of the research consistency. Freeze drying technology is selected for the comparative cost analysis including manufacturing costs and energy consumptions. Results shows infrasound-integrated technology has a relatively low energy consumption whereas it costs more manufacturing costs than freeze drying technology. Research assumptions, limitations and recommendations for this research are described in this article. From the author’s perspective, this paper can be used as an initiation and instruction for larger scale researches in regard of infrasound-integrated algae dehydration/drying.

This thesis explores the ways in which LGBTQ+ individuals in Philadelphia ascribe significance to various places based on oral history interviews and additional primary source material collected initially for the National Park Service Northeast Regional Office’s LGBTQ+ Heritage Initiative. By examining stories from LGBTQ+ individuals of places that matter most to them in Philadelphia, this thesis argues that historic preservationists can expand their definition of significance to include personal testimony and broaden their practices to better engage the communities whose histories they seek to preserve. / History
