Nitrogen fixation among boreal feather mosses along a clear-cut chronosequence

The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems. This study investigates the biological N2 fixation rates of two boreal feather moss species (Pleurozium schreberi and Hylocomium splendens) along a chronosequence from clear-cut to mature forest, as well as the vegetation characteristics along the chronosequence. Measurements and samples were collected from 32 forest sites that were classified into four age classes (clear-cut, pre-commercially thinned, thinned and mature forest). The sites were located near the city of Arvidsjaur in northern Sweden.

Den goda platsen : om varför vi tycker mer om vissa platser än andra

How can man´s place preferences be explained? What aspects influence our experience of place? This essay attempts to define a good place to be drawing from sources of environmental psychology as well as other landscape theories and relating these findings to the landscape architect?s field of work. Physical place properties, like physical elements and their juxtaposition in space are examined in relation to place preferences as well as psychological properties, such as place attachment and place identity due to cultural or social aspects.There are strong cross-cultural similarities in our place preferences but there are also some differences. Natural elements, like trees or water, are widely preferred over man-made ones, like buildings, roads or fences.Man seems to be sensitive for the balance between different place characteristics, like the balance between ?soft?, natural, elements and ?hard? man-made ones or the complexity versus the legibility of place.

Enkla och positiva inslag i kemiundervisningen i grundskolans tidigare år

Samhällets behov av naturvetenskapliga problemlösningar när de rör kemin ökar mer och mer, men ungdomars kunskaper och intresse för kemi har minskat det sista decenniet. Den kemididaktiska forskningen pekar ofta på brister och även om lärarens praktik har en avgörande betydelse för elevernas lärande är det väldigt lite av lärarens praktiska undervisnings metoder som kommer till tals. Syftet med denna studie är att sammanställa och lyfta fram det positiva i det praktiska arbetssättet som några yrkesverksamma lärare använder sig av för att uppfylla något eller delar av kursmålen i kemi för årskurs 5. Resultatet kan förhoppningsvis användas för att få fler lärare att våga undervisa i kemi i grundskolans tidigare år. Studien genomfördes genom djupintervjuer.Genom att välja en flexibel undervisning där elevernas intresse och förmåga var i fokus kunde lärarna genomföra en undervisning som bidrog till att delar av de beskrivna målen skulle kunna uppfyllas.

Intellectual Property Rights in Software : A Critical Investigation from an Ethical Perspective

The development of software was considered until the beginning of the 1990th as a cathedral like product development in closed companies. This way of development changed in the last decade. Open source software (OSS) development challenged this consideration significantly. OSS is produced in co-operation by skilled people, distributed and used by many moral agents. The result, the software itself, can be studied and modified.

Kanten : mötets poesi

Water connects heaven and earth. Water is the most obvious element of nature. To move in water is for me more than cooling of on a hot summer?s day. It is about freedom and the feeling of being above the state of things.

Restaurering av våtmarker; Inventering av vadare och andfåglar vid Norra Lingenäset

The release of green house gases and the environmental impacts humans have on the environment are huge and might cause irreversible changes to our earth. Meat is considered to have large impacts on the environment, especially beef meat and therefore there have lately been considerable discussions on the sustainable level of meat consumption and production. The main goal with this thesis is to study sustainable meat production and meat consumption in the county of Dalarna in Sweden. Indicators for sustainable meat production and meat consumption were developed and applied on three cases. Interviews were carried out with a municipality in the region that represents the consumer and three beef farmers that represents the producers.

Utomhuspedagogik i skolan

Nature is in many ways considered a source to both physical and mental health among people. Trends in today?s society reveal that children become more distanced to nature. Seen from the perspective of sustainable development this trend is considered crucial: it is of importance that children in their early ages experience nature positively in order to develop a dedication towards environmental issues as adults.The purpose of this study is to investigate how teachers use outdoor learning as an educational tool. Research data were collected through a series of interviews.

Projektledarutbildningar på svenska universitet och högskolor : Innehåll och relevans för yrkesrollen

One year Master's thesis, Degree of master in Business and Economics, School ofBusiness and Economics at Linnaeus University, Management, 4FE10E SpringSemester 2014.Author: Johanna Björklund and Sarah Gustafsson.Mentor: Magnus Forslund.Title: Lean in the public sector - Potential barriers to a long-term Lean work.Background: Organizational changes are something that is constantly done inorganizations, and in the last decade, there has arisen a plethora of different changemodels. A reorganization that is popular among companies today is Lean. Lean is aconcept that was developed within the Japanese automotive industry, but has evolvedfrom the Japanese shop floor and is now a concept that can be found in, for example,several Swedish municipalities.Purpose: The purpose of this study was to create an understanding of why the conceptLean may have difficulty getting a hold in the in the long term.Methodology: The study was done with a qualitative research approach and through anabductive approach. As we intended to create an understanding, of what potentialbarriers that may affect that a Lean work, in some cases, does not become a long-termcondition, it seemed natural to choose a hermeneutic approach to knowledge. Theempirical data collected via individual unstructured interviews, through a groupinterview, and by non-participant observations.

Klimatanpassning med grönstrukturplanering : Med exempel från Malmö stad

Climate change is expected to lead to increased rainfall and higher temperatures, among other things. This will have a major impact on our cities. Floods can lead to property damage as well as damages to human and animal health. Higher temperatures will increase the frequency of heat-related health risks and premature deaths. The consequences of climate change will be particularly large in our cities because of the city's morphology with a high amount of paved surfaces and buildings that affect the natural processes in areas such as drainage and absorption of solar radiation.

En park för alla

This Master Thesis is a product development project that has been carried out in cooperation withLappset Sweden AB.The purpose has been to develop a group of products suited for parks andtraditional playground locations. The specific target area has been courtyards of newly builtresidential areas. (These pieces of open land resemble glades that can be found in the forest,which in Swedish is called ?gläntan? and has given name to the product family). Therefore thedesign should match contemporary architecture.

Uppförandekoder inom livsmedelsindustrin : en fallstudie

The world has changed its understanding of environmental issues dramatically and more people are showing awareness of social and environmental problems. Various stakeholders have increasingly begun to show an interest in how companies are taking responsibility for their actions. This has led to an improved activity amongst organizations to make their production consequences positive. They work with Corporate and Social Responsibility (CSR). In order to communicate their responsibilities, many companies work with CSR and ethical guidelines.

De bortglömda stenarna : om byars äldre gränsmarkeringar och rågångar i Ekeberga socken

This essay is about the hamlets´ older boundaries, i.e. boundary lines (?rågångar?) and boundary markers in the form of rocks, and an own survey of two hamlet boundaries in southeast Sweden. Many of the boundary rocks were subjected to unintentional damage or destruction that arose during forestry activities, the excavation of ditches, or road construction. Boundaries between hamlets sparsely populated areas were not clearly defined from the beginning, but were established initially in the form of boundary zones, that often consisted of wetlands, watercourses, or mountain heights.

Parc de la Villette & Bulltoftaparken : en jämförelse mellan parkerna

I Malmö finns en stor park som anlades på 1980-talet och som heter Bulltoftaparken. Samtidigt i Paris anlades Parc de la Villette efter att man haft en tävling om parkens utseende och chefsarkitekt. Här någonstans började mina tankar att cirkulera runt det faktum att parkerna ser olika ut, men båda är anlagda från 1982 ungefär och framåt. Finns det några andra gemensamma nämnare från början? Hur såg deras tillkomst ut? Vad bidrog till utformningen av Parc de la Villette och vad bidrog till utformningen av Bulltoftaparken? Genom att titta på historik, tillkomst, arkitekt och landskapsarkitekter, idéförslag och struktur, jämför jag parkerna och ser vad som skiljer dem åt och vad de har gemensamt.

Thuja plicata - etableringsförsök av jättetuja med fyra olika provenienser

Future climate changes may lead to an interest of alternative and foreign forest tree species in order to spread the risks in forestry. Douglas fir, Sitka spruce, Freemont cottonwood and hybrid aspen are examples of popular foreign tree species that along with western red cedar could have a future in the Swedish forests.Södra Skogsägarna and SLU have collaboration in establishment of foreign species in Swedish forests.The purpose of this study was to analyze and present the establishment of western red cedar, and to survey and illustrate injuries of freeze drying and other damages like deer browsing, vegetation and insect attacks. The study included four different provenances, and spruce as a reference, planted in two locations ? Asa and Släne.Western red cedar is despite its name a conifer of the cupressaceae family with defined secondary characteristic and gets along well with an overstory. Western red cedar grows often in mixed stands with similar conifers and its natural habitat is within and in the area near to British Columbia.The study included two series of field inventories, one made in the summer and one in the autumn 2013, three growing seasons after plantation.

The secret life of Bacillus anthracis

Bacillus anthracis is the causative agent of anthrax, a serious and globally distributed zoonosis affecting a wide range of wild and domestic animals, invariably also humans. However, although known to humans since biblical times, much remains to be elucidated concerning the ecology and transmission of this bacterium. Of particular interest is the Bacillus anthracis spore, the uptake of which is the predominant way to contract anthrax and which is legendary for its resilience in the environment and thus crucial for persistence and spread of the disease. Hence, the aim of this study is to review the natural transmission of Bacillus anthracis and investigate potential means by which soil persisting Bacillus anthracis spores reach concentrations sufficient to infect susceptible hosts. When reviewing the literature, three different theories can be distinguished. Firstly, ?the incubator area? hypothesis suggests that favourable soil factors, possibly in association with amoebas, may constitute an environment supporting repeated spore-bacterium-spore cycling, thus increasing the local amount of spores.
