A consequence of eutrophication in the Baltic Sea is growth of algae that accumulates in the coastal areas and beaches. Dense algal mats may cause anoxia or hypoxia and greatly reduce the recreational value of the area. Algae also functions as hyper accumulators of heavy metals and their metal levels may become toxic to higher trophic levels. The project Wetlands, Algae and Biogas (WAB) aims at removing algal beach cast for commercial use in biogas production and further use of the fermentation residues as fertilizer. Collection of algae would remove both nutrients and heavy metals from the Baltic Sea but leave us with large amounts of algae containing heavy metals. A concern for the biogas production based on these Baltic algae is the effects from the heavy metals, during fermentation, in the residues and the use of them as fertilizer. A literature review shows that the levels of heavy metals should not inhibit the biogas production but during the fermentation there is a loss of (48%) biological material and the metals are concentrated in the residues. Samples of algae from Trelleborg (SE) show higher concentrations of cadmium (Cd) than algae from Poland (PL). The Swedish residues border or surpass the legislative amount of heavy metals that are allowed to be applied to arable land in Sweden. This is both due to the higher concentrations of heavy metals and the differences between European and Swedish legislation. To use the residues as fertilizer detoxification is required, mainly for Cd in Sweden. There are effective methods, chemicals and ion exchangers (70-80%), for removing heavy metals from organic leachate. But these methods lack testing on a large scale, the costs and the environmental aspect of these methods on tons of algae per year are unknown. Co-fermentation with a suitable substrate would dilute the heavy metal concentration and could reduce possible problems such as hydrogen sulfide accumulation in the biogas. Another possible pathway for dealing with the heavy metal rich residues is as fertilizer for non-food crops such as the biofuel species willow (Salix). Willow is a fast growing tree that is a known accumulator of heavy metals and can be used as a remediation for contaminated soil. Based on the metal concentrations and respective legislation, estimations of 20 000 ha of willow for Trelleborg and 400 ha for Sopot beach (PL) is needed to process harvested algae. / Wetlands, Algae and Biogas (WAB)

Ett examensarbete i Arkitektur om två experimentella villor, konst, design, modernism och framtidstro. Allt samlat i en tidning. (svenska / engelska) Villorna är belägna på en skogstomt i Horndal, i södra Dalarna samt på en havstomt utanför Trelleborg vid Gislövs Läge.

Studiens syfte var att undersöka otryggheten hos Trelleborgs kommuns kvinnor och undersöka samvariationen mellan otrygghet i offentliga miljöer och kvalitet på deras sociala nätverk. Syftet var även att undersöka vad som låg till grund för kvinnornas oro samt vilka brottstyper de var mest rädda att utsättas för. Antagandet var att kvinnor med ett starkare socialt nätverk upplevde en lägre otrygghet. I begreppet socialt nätverk inkluderades frekvensen av kontakt samt vilket stöd deras privata relationer genererade. Empirin samlades in i centrala Trelleborg och 100 kvinnor deltog, kvinnorna var mellan 20 och 87 år. Datan analyserades statistiskt främst genom jämförelser mellan medelvärden men även genom regressionsanalyser och korstabuleringar. Resultatet visar att de kvinnor som erhöll stöd från sitt nätverk hade en signifikant lägre otrygghet än de som inte erhöll stöd. Inga tydliga samband fanns mellan storleken på nätverken- eller vilka relationer de hade till sina kontakter. Orsaken till oron hos flest kvinnor och även till majoriteten av de mest otrygga var att brottsligheten var hög i Trelleborg och det brott som flest kvinnor oroade sig att utsättas för var rån. / The aim of this study was to examine women’s fear of crime in Trelleborg and the relationship between women’s fear of crime in public places and the quality of their individual social networks. The hypothesis was that women with a better quality of their network will have lower feelings of fear of crime. The aim was also to study the sources to their fear and which crime they feared most. In the term social network women’s frequency of contact and which support their relations generated was tested. Survey data was collected from 100 women, aged 20 to 87 years in Trelleborg city. The empirical data was statistically analyzed through crosstabulations, Anova, t-test and simple linear regressions. The results show that the largest correlation between less fear of crime and the social network was connected to which support the women received through their network. No strong support was found for the importance of the numbers in the network or which kind of relation women with less fear had to their contacts. The most common source to fear was the knowledge of high crime rates and the crime that most women feared was to be robbed.

Denna studie utreder hur hållbara utvecklingsinitiativ inom klimatanpassning inramas i kommunala visioner från de två svenska kommunerna Kristianstad och Trelleborg. Båda städerna befinner sig i prekära geografiska lägen och är speciellt i riskzonen för de stigande havsnivåerna. Klimateffekterna är redan här och havsnivåerna förväntas att bli allt värre i samband med den stigande temperaturen. Kommunerna har ett viktigt ansvar i klimatanpassningen. Kommunerna ansvarar för den fysiska planeringen och därav ansvar för mark- och vattenregleringen. Syftet med studien är att undersöka huruvida Kristianstad och Trelleborg lyckas sammanfläta klimatanpassningsplaneringen med alla tre hållbarhetsdimensioner (ekologiska, sociala och ekonomiska). Studien avser att utvärdera hur dessa dimensioner värderas i kommunernas kommunala dokument, genom en kvantitativ innehållsanalys. Tidigare forskningen tyder på att det är svårt att synkronisera de tre hållbarhetsdimensionerna och istället står de i vägen för varandra och tenderar att favorisera den ekonomiska hållbarheten. Resultaten från Kristianstad efterliknande den tidigare forskningen, där de ekonomiska värdena överskuggade de andra hållbarhetsaspekterna. De var snarlikt mellan de ekologiska och ekonomiska, men framförallt var det den sociala hållbarheten som fick väldigt lite uppmärksamhet. Trelleborg fick dock andra resultat. Det var fortfarande en väldigt svag balans mellan dimensionerna, dock var värderingen av dimensionerna annorlunda. Den sociala, men framförallt den ekologiska, värderades högre än den ekonomiska.

This degree project is done in collaboration with Vinnergi AB at their officein Halmstad. The aim for this project is to deliver a proposal for a new charging station in Trelleborg with focus on technology implementation. With an increase in electrification in the transport sector comes the need to construct more charging stations in order to keep up with the increased demand for charging points for electric vehicles. This report will cover research for existing chargers at the same location in order to determine the current usage of those chargers, the amount of chargers that the nearby electrical grid can handle as well as a power quality study for the existing electrical grid. To reach the specified goals, simulations of the actual electrical grid were conducted along with several calculations and technology considerations that were partly based on the simulations. This research came up with a new proposal for a charging station with two charging posts for fast charging with a charging capability of between 175 kW and 350 kW. Cables, breakers and a grounding system for the chargerswere evaluated and chosen along with a fundamental budget for the whole project. This proposed charging station will extend the charging capabilities in the area and be a part of keeping up with the increased demand for fast andreliable charging in Trelleborg.

In relation to last year’s introduction of Digital Archaeological Process this study is supposed to investigate the opportunities of using quantitative methods on the archaeological material. The subject of the investigation is to problematize and process the concept of ”central places”. The investigation is based on a combination of qualitative and quantitative methods executed on seven different grave- and settlement areas during the Iron Age in Skåne. The archeological material is gathered through archaeological reports and later processed in tables. The concept of central places is often based on luxury finds and places with much archaeological material. Quantitative methods on archaeological material are a possibility by many reasons. For example by getting an overview of each grave- and settlement area which is an opportunity for more interpretations. DAP is an opportunity to restore the archaeological material during excavations for future research. The introduction of DAP is a step in the right direction for future archaeology.
