Det Nya Sydafrika : Nationell identitet och bygget av en regnbågsnation
The South African nation and society have experienced significant changes and reforms over the last decade. Less than ten years ago black and white people were not even allowed to share a bench in a park. Today they are expected to live side by side in what is called a"Rainbow Nation". When a new society is built language plays an important part. The language constantly reproduces daily the small things that identify a nation and the people living in it.
Termohalin cirkulation i Nordatlanten
Den termohalina cirkulationen är en global havscirkulation driven av densitetsskillnader, som gör att varmt vatten transporteras mot polerna och kallt vatten mot ekvatorn. Densiteten påverkas av temperatur och salinitet (och tryck, som vanligtvis ignoreras). Därför heter cirkulationen termohalin. Saliniteten minskar när vatten tillförs genom nederbörd, havsissmältning eller landavrinning. Saliniteten ökar genom avdunstning och isbildning.
Storlommens (Gavia arctica) häckningsframgång relaterad till vattenkvalitet
This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .

Regionbiblioteken i Tanzania en fältstudie av den offentliga biblioteksservicen
This masters thesis concerns the Public Library Service in Eastern Africa, Tanzania. Our subject was developed through a feasibility study that gave us comprehension that developing countries have individual problems concerning books and libraries. We understood that the main problems were the libraries financial situation and their dependence on aid. We also understood that the libraries do not have the resources to satisfy the society as a whole. The major questions raised in this study are: - How do the regional librarians describe their work situation? -Which role do the Regional Librarians have in society? Data was collected through interviews and observation, and the study is a qualitative case study.

Musik som ett specialpedagogiskt verktyg för barns språkutveckling : Fem sydafrikanska pedagogers syn på musik som pedagogiskt verktyg
The purpose of this essay is to study if and how five South African educators work with music as a special pedagogical tool in children's language development. To achieve the purpose of this study, two research questions were created. As method, interviews of a qualitative character were chosen. The aim of the method is to give the educators the opportunity to think about and use their own experience before answering the questions.The result shows that the South African educators are not using music as a special educational tool. They rather use music as an everyday educational tool to promote children's language development. The result indicates that music in educational activities promotes children?s communication with each other.
Skredriskutsatta områden vid ett förändrat klimat - Konsekvenser för vattendistributionen i Göteborg
This report presents suggestions and recommendations on how to convert an old industrial building, built in 1958, to an office hotel. One of the main criteria was that the floor plan should be flexible. The building is situated at Jonsereds Fabriker and the study was conducted for Hantverkslokaler i Göteborg AB, the estate owner.The survey is initiated with study visits at various office hotels, together with studies of literature regarding office planning. One conclusion from the study visits is that meeting-places, where the different companies can meet and exchange ideas and services, are important. Another one, and probably the most important parameter when planning offices is that they should have windows.
Uttryck i sten : En studie av röjningsrösen, stensträngar och husgrundsterrasser under mellersta järnålder i Uppland
This thesis deals with two types of agrarian remains in relation to settlement remains; clearance cairns, low stone walls and house terraces in the area of Northeastern Uppland and the area north of Lake Mälaren, during the middle Iron Age. The aim whit this thesis is trying to get a better understanding of the relation between agrarian and settlement remains in Uppland. Three places have been chosen where these three elements are present and they are interpreted through Richard Whites concept of middle ground but also Landesque capital. The three elements have shown to be expressed in different ways in all three sites. It is possible to see two areas with different traditions, but also to see two areas that closely interact with each other, this opens up for a new discussion around agrarian remains in both areas.

Secondly; it also discusses if the automation has changed the librarys condition. The empirical material consists of fifteen interviews with librarians and students. The empirical material itself has functioned as a base when discerning the analytical themes.
Matematik : Pedagogers syn på inlärning av matematik i en förskola
Many researches demonstrates that children who deal with matematics in a meaningful context early in their age, will manage a much wider context later in school. The purpose of this work is to highlight the importence of teacher´s view on matematics and how matematics can be visible for the children when they are in a preschool age. Im trying to promote the importance of mathematics wich characterizes much of our society. Highlighting todays nursay?s and the fact that there is plenty of good enviroments for the learning of mathematics.

Dags att tjäna lite pengar! : En studie om möjligheten att generera överavkastning genom att imitera insynspersoner inom den svenska oljebranschen
Vi har studerat möjligheten om det går att tjäna pengar på kort sikt genom att imitera insidertransaktioner efter det att information om transaktionen har publicerats offentligt. Studien begränsades till att endast undersöka köp- och säljtransaktioner för oljebolag som kan handlas på Stockholmsbörsens huvudlistor samt First North. Studien genomfördes i form av en eventstudie där vi med hjälp av statistiska tester undersökte om det existerar en signifikant skillnad i den dagliga avkastningen före och efter en viss insidertransaktion ägt rum. Detta visade sig inte vara fallet utan de fluktuationer som påvisades var ej enhetliga och kunde inte bevisas bero på insynstransaktionerna..
En jämförelse av sitkagranens (Picea sitchensis) och den vanliga granens (P. abies) produktion :
Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the
West Coast of North America, from Alaska in the north to northern California in the south.
Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs
in single pure as well as in mixed stands.
The main purposes of this study were to describe the Sitka spruce growing characteristics and
the volume production in comparison to spruce (Picea abies). The possibility to predict future
volume production by using prognosis tools designed to be used on spruce were also studied.
The material that has been used in this study are permanent sitka trials established by the
Faculty of Forestry fixed Sitka trials and also material gathered in this study.
A literature study was also carried out in order to determine the Sitka spruce growing
characteristics.
Sitka spruce has a high adaptation and a high volume production on a broad scale of soil
types. The tree species is a pioneer species that has a fast early growth and in combination
with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the
single most limiting factor for where the Sitka spruce can be planted is frost. This factor can
be limited by using plant material with a well-suited provenance.
According to the literature, the Sitka spruce has an average total volume production that is
between 20-40% higher than spruce.
Reducerad jordbearbetning : en fallstudie
This is a study made because I would like to see how much money can be saved when
reduced soil preparations is used. This is a case study, the farm is located in the north
vest part of Skåne, Sweden.
I have calculated with four different soilpreparation methods.
Alternative 1: Conventional soil preparation, the way the farm is managed today.
Alternative 2: Ploughing on depth of 12 centimeters, with a ridge packer followed with
sowing.
Alternative 3: Eco-tillage
Alternative 4: Direct drilling
The results of my study showes that Alternative 2 is the most profitable. Alternative 4 is
very good if you see to dieselexpenses and hours of work, but the yield is far to low.
If the numbers are further analized, it showes that in spring barley the differense
between Alternative 2 and Alternative 4 is at a minimum. So if there is lack of time for
one reason or another, this might be an alternative in spring barley.
The differense in how the farm is managed today and the most profitable alternative in
the study, Alternative 2 showes that it can be saved up to 60 940 SEK..
