Meeting, greeting & seating : a design proposal for Magomeni garden, Dar es Salaam, Tanzania

More than fifty percent of the world population today lives in cities, and the pressures of urbanisation are particularly present in developing countries. As landscape architects, it is important to gain knowledge about the effect of urbanisation and ways to prevent the negativities. Experiencing the effects in person in a developing country, as well as learning from and about other cultures, enhances the understanding for global situations. Dar es Salaam is located in one of the most rapidly urbanising regions in the world, which puts pressure on the environment and the humans living in it. Lack of means to regulate land development has led to a situation where expansion of unplanned settlements occurs, with spatial disorder as a consequence. This has in the extension led to a decreasing amount of publicly available and qualitative green spaces, and degradation of the few ones that exist. There are facts that strengthen the status of urban parks, which especially becomes relevant in developing countries where many people live in sparse and exposed conditions.

Naturliga filtermaterial för reduktion av metaller i dagvatten

Förorenat dagvatten från Stena Gotthards metallåtervinningsanläggning i Eskilstuna har filtrerats genom kolonner innehållande två olika adsorbenter, torv och furubarksflis. Torv är en organisk jordart som främst används som bränsle och furubarksflis är en biprodukt från skogsindustrin. Båda filtermaterialen är relativt billiga och finns i stora kvantiteter i Sverige. Filtermaterialen har visat sig ha varierande kapacitet att adsorbera metaller i vatten på grund av själva materialet samt vattnets sammansättning. Resultatet från den här studien visar att av de två undersökta filtermaterialen så har furubarksflis störst kapacitet att reducera bly, koppar och zink från det specifika dag vattnet..

Tillgängligt landskap : spänger i naturmark

The title of this thesis is ?Accessible Landscape - boardwalks in nature areas?. The main purpose of this thesis is to show how you can increase the accessibility for disabled people by constructing boardwalks in nature areas. The platform for the thesis is a study of litterature on boardwalks, accessibility and disabilities. After defining these terms I made three excursions to three different locations in the south of Sweden. During the excursions I evaluated the boardwalks situated in each of the areas through preferences such as the construction of the boardwalk, its design and the accessibility. After the excursions I interviewed managers of the areas I visited, and people working with disability questions in the municipalities where the excursions took place. To know how to make a boardwalk accessible you need to have knowledge about certain concepts, rules and recommendations. My thesis deals with aspects such as: *Accessibility *Disability *Rules and recommendations when building boardwalks *Real life - evaluation from the excursions and interviews with the managers The result shows that accessibility is a hot topic in Sweden and a lot of improvement is being done with fi nancial support from the European Union.

Det viktiga mötet: En studie av intern interaktion i företagsinkubatorer

Entrepreneurship is considered essential for the Swedish economy, as well as globally. Accordingly,massive efforts are put into creating environments that successfully can support new ventures. The business incubator is a prominent part of these efforts and is important especially for the knowledge shared within its internal network. The aim of this study is to further explore how different activitieswithin the incubator can influence the interaction, and thereby the construction of social capital,among the incubatees. Using a qualitative case study of three incubators, and the framework of theincubator model, it is concluded that three distinguishing components within the framework influence the interaction, namely infrastructure, mediation and business support.

PCB i byggnader : Handlingsplan för saneringsarbetet i Eskilstuna kommun

Polychlorinated biphenyls, PCBs, were used in elastic sealants in buildings during the years1956-1973. Studies of PCB have revealed that it is harmful for humans and animals,especially water-living predators and other top-predators. It is also a persistent organicpollutant and remains in the environment for a very long time. To reduce the levels of PCB inthe environment, it has to be removed from the buildings. According to Swedish law, theproperty holder has to decontaminate sealants with a PCB level of 500 mg/kg or above.

Är marknaden för utsläppsrätter effektiv? : En eventstudie av klimatmötet i Köpenhamn

Inledning: Människans utsläpp av växthusgaser påverkar klimatet kraftigt, internationellt samarbete är avgörande för att minska det globala utsläppet. EU:s utsläppshandel inleddes i januari 2005 och omfattar ca 1300 anläggningar inom industri och energi produktion. Terminer på utsläppsrätter introducerades i april 2005 och i samband med det öppnades European Climate Exchange som idag är den ledande och mest likvida marknadsplatsen för handel med utsläppsrätter i Europa och internationellt. I enlighet med hur aktiepriser påverkas av utomstående faktorer generellt på aktiemarknader vill författarna undersöka om priserna på utsläppsrätter påverkas av en utomstående faktor.Syfte: Syftet med studien är att undersöka hur priset på utsläppsrätter på ECX spotmarknad reagerar på klimatmötet i Köpenhamn samt om marknaden för utsläppsrätter är effektiv.Metod: Genom att använda finansiella marknadsdata kan en eventstudie mäta vilka följder ett specifikt event har på det undersökta objektet. För att kunna värdera hur eventet påverkar priset på utsläppsrätter tillämpas en uträkning av den abnorma avkastningen, vilket är den verkliga avkastningen minus den normala avkastningen under eventfönstret.Teoretisk referensram: Det teoretiska angreppssättet kommer att utgöras av den effektiva marknadshypotesen.

Undervegetation : användning av vedartade marktäckare i anläggning

The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull. The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.

Lactobacillus reuteri som probiotisk terapi mot bakteriell vaginit hos avelsråttor :

I was part of a small project team of museum staff. The purpose of this exhibition was to show how cultures have met and influenced each other throughout history. The National Historical Museum has in its collections and exhibitions several examples of objects that has been imported from or inspired by other cultural areas.

Optimerande av gasanläggning - genom värmeåtervinning och förlustreducering. Gässlösa Reningsverk

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.

Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

Klassificering av utländska dotterföretag

Background: Companies often invest in foreign subsidiaries and that gives rise to translation exposure. Translation exposure arises with the consolidation of the foreign subsidiary and depends on the rate of exchange that are used for translation of the foreign subsidiary. In time several different methods of translation and recommendations has been developed. Companies listed on OM Stockholmsbörsen shall follow RR8. According to RR8 a classification of foreign subsidiaries as indipendent or integral to the parent company determines which method of translation that should be used.
