Myllrande våtmarker och vektorburen smitta : Våtmarker och dagvattenhantering i planeringen

En åtgärd som allt mer förespråkas runt om i världen för att uppnå en hållbar utveckling är att planera för öppen dagvattenhantering genom att bland annat återställa våtmarker och uppföra dammar och diken. Att dessa åtgärder även innebär fler potentiella habitat och större populationer av myggor, som kan vara vektorer för smittor, är dock ett problem som sällan diskuteras i planprocessen.Planprocessen förutsätts vara en rationell process som tar hänsyn till alla ståndpunkter och leder till den bästa lösningen. I detta arbete framkommer dock indikationer på att planprocessen kring öppen dagvattenhantering snarare går att betrakta som ett utslag av makt där handlingsutrymmet över problemformuleringen varit avgörande. Planprocessen förefaller att genom subtila maktordningar stärka vissa aktörers inflytande på andras bekostnad. Detta har medfört att ett biologiskt och tekniskt synsätt tycks dominera föreställningen om vad öppen dagvattenhantering innebär, vilket lett till att de medicinska synpunkterna inte kommit till uttryck utan exkluderats från planprocessen..

?W? zh? ramla-le? : Om kinesisk-svensk kodväxling hos tvåspråkiga barn i Sverige

This thesis focuses on Chinese?Swedish code-switching of bilingual children in Sweden. The purpose is to, through a case study, study what Chinese?Swedish code-switching looks like in daily conversations between bilingual children and their parents. Three main questions are formulated from the purpose of the thesis, foucusing on the types and frequencies of code-switching, the grammar of code-switching, and the motivation of code-switching.The linguistic material comes from voice recordings of naturally occurring conversations between three children and their parents, which are transcribed afterwards.

Detektering av in- och utandning vil bilkörning med hjälp av Matlab

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

Svenska preferensaktier: Ett eget kapital- eller skuldinstrument?

On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.

Interspecies embryo transfer in South American camelids : a field study

The aim of this study was to investigate the possibility of performing inter-species embryo transfer under actual field conditions in the natural habitat of South American camelids. In this study embryos from llamas were transferred to alpaca recipients. In a parallel study alpaca embryos were transferred to llama recipients. All animals used were free of uterine and ovarian abnormalities detectable by rectal palpation and /or ultrasound examination. Embryos were harvested twice after single ovulation in 10 mated female llamas and non-surgically transferred to synchronized alpaca recipients.

Utemiljön ur ett ekosystemtjänstperspektiv : undersökning och gestaltning med fokus på en bostadsgård i stadsdelen Norra Fäladen, Lund

Målet med detta arbete är att undersöka vad begreppet ekosystemtjänster kan innebära i den urbana utemiljön och hur ett ekosystemtjänstperspektiv kan användas för att beskriva och gestalta grönytor i staden. Bakgrunden är det växande intresset för hållbar stadsplanering och hur landskapsarkitektur kan bidra till detta. Frågeställningarna som har varit utgångspunkt för arbetet är: ? Vad innebär begreppet ekosystemtjänster i mindre, urbana sammanhang? ? Vilken roll skulle ett ekosystemtjänstperspektiv kunna ha vid gestaltning av utemiljöer i mindre skala? Arbetets metoder består av studier av litteratur, studiebesök i Malmö, Lund och Helsingborg samt av ett gestaltningsförslag för en bostadsgård i området Rådhusrätten i Lund. Begreppet ekosystemtjänster fick sitt genomslag med Millennium Ecosystem Assessments rapporter i början av 2000-talet och betyder de tjänster och fördelar som människor får från naturen. Det inkluderar exempelvis odling av mat, rening av vatten och luft, rekreation, hälsa och symboliska värden.

Vatten som väcker sinnena : - förslag för införande av vatten i Alnarps rehabiliteringsträdgård utifrån några miljöpsykologiska teorier

Alnarp?s Healing Garden is a place for rehabilitation as well as an ongoing multidisciplinary scientific research experiment. The garden is built on research results from the disciplines of Landscape architecture, Environmental Psychology and Garden Therapy. In the garden, people diagnosed with burnout syndromes are being rehabilitated. The participants need safe and calm environments which activate their bodies self healing systems. Theories show that water as an element, per se, increases the observer?s preference for an environment.

Vilken kvinna? En intersektionell diskursanalys av ämnesordlistan i databasen KVINNSAM

The aim of this thesis is to critically analyse the subject heading list in the database KVINNSAM at Kvinnohistoriska samlingarna. This list is intended for the retrieval of gender specific information and the subject heading women is implied. The main question is: which woman is represented in the list? The thesis analyses specifically the representation of disability, ethnicity and other sexualities than heterosexuality. Kvinnohistoriska samlingarna, the concept of gender studies and KVINNSAM is presented.

Bibaggar i Halländska grustäkter

This report is a result of a first survey of Halland?s gravel pits as an assignment from the County Administrative Board of Halland. The focus has been on Apalus bimaculatus, since the Swedish Environmental Protection Agency are creating a restoration program as it is red listed as Near Threatened. The purpose was also to get an overview of the pits since the County Administrative Board wants to continue this project. Apalus bimaculatus is easy to overlook since it is a short-lived beetle and it lives early in the spring.

Plesiomonas shigelloides ? en ovanlig orsak till diarré hos katt? :

Plesiomonas shigelloides is a gram-negative, oxidase-positive rodshaped bacterium of the family Enterobacteriaceae. P. shigelloides is most frequently isolated in tropical and subtropical areas, but has also been isolated in colder areas for instance in Sweden. The primary natural habitat of the bacterium is fresh water and indirectly waterliving animals, but the bacterium can also be recovered from humans, mammals (of which cats are over-represented), birds, insects and poikilothermic animals. P.

Arbetsmotivation efter mammaledighet

Att gå åter till arbete efter en period av mammaledighet kan för många kvinnor upplevas negativt. Tidigare forskning har visat att en kvinna kan känna känslor som ångest, rädsla och stress för att gå åter till arbete, men även att pensionen kan sjunka drastiskt för en kvinna som har varit mammaledig en längre period. Det är därför värdefullt att undersöka om mammaledighet har några effekter på arbetsmotivationen. Detta examensarbetes syfte är att undersöka arbetsmotivationen efter mammaledighet med frågeställningarna om det finns förändringar i arbetsmotivationen efter mammaledighet och om mammaledigheten kan påverka arbetsmotivationen på något sätt. Resultatet av intervjuer med 10 kvinnor visar att arbetsmotivationen var relativt hög efter en period av mammaledighet, men att andra faktorer för arbetsmotivationen hade blivit alltmer viktiga.

Habitatpreferenser hos tjockskalig målarmussla (Unio crassus) med avseende på vattendjup och beskuggning.

The thick-shelled river mussel (Unio crassus) is a red listed species classified as Endangered (EN) and is also considered within the Habitats Directive. The distribution in Sweden is fragmented and it is mostly occurring in the south eastern parts. We investigated the presence of Unio crassus in a section of the stream Storån, Östergötland County, from Falerum to the inflow into Lake Åkervristen. The environmental parameters investigated were water depth, bottom substrate, shading, water velocity and the slope over the water surface. In this thesis I have focused mainly on water depth and shading, comparing sites with and without mussels.

Rissepareringens effekter på viltets nyttjandegrad av GROT

Successful forest regeneration is a prerequisite for sustainable forest management. Therefore, it is important to prevent browsing damage on the commercially important tree species Scots pine. In this study I have tested a new alternative way to increase the available amount of forage and increase the use of these resources by especially moose. The method is based on a slash treatment at harvest, where the accessibility of slash as forage is increased during final felling or commercial thinning by gathering the slash and putting the Scots pine slash on top of the slash piles. This study has compared the availability of forage, the amount of browsed biomass and the number of fecal pellet groups between conventional and slash treated stands after final felling and commercial thinning in southern Sweden.

Predation som selektiv kraft bakom differentiering av populationer av sötvattensgråsugga, Asellus aquaticus

Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.

Vad tycker medarbetarna?: en studie av medarbetarnas
pensionspreferenser vid LKAB

One trend that can be seen in the EU countries is that employees want to exit from the workforce before they turn 60 years. A Dutch study of some EU countries has noticed that an early retirement from labor in many countries is considered as a social right. This has created an ?early exit-culture?. Large early outflows of the labor have created an institutionalization, the right to cease work early.
