The effects of Gotland pony grazing on forest composition and structure in Lojsta hed, south eastern Sweden
Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.
Jordlöparfaunan i bestånd av contortatall (Pinus contorta) och svensk tall (P. sylvestris) 1987 och 2010
In the 1970´s the North American lodgepole pine (Pinus contorta) was introduced to Sweden in large scale. The lodgepole pine affects its new environment different from Scots pine (P. sylvestris), leading to a change in biological diversity.
Forestry today affects the ground beetle fauna (Carabidae). Habitat specialists associated with older forests are first affected. When the canopy closes again after a clear-cutting species that prefer open habitats reduces and those who prefer mature/closed forests increase.
In this study we compare differences in diversity and community structure of ground beetles in stands of lodgepole pine and Scots pine.
Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?
Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.
Social Construction of Crisis: The Constructed Realities of SAS Ground Service Employees Regarding the Preparatory Period of Strategy 2011 Organizational Development Program.
The thesis explores an ongoing dialectical process between different levels of employees including top management to workers of Scandinavian Airline Service (SAS) regarding a new change program and to find out the possible social construction among them. In particular, it searches for the constructed reality of SAS ground service employees at Malmö Airport with regard to the preparatory stage of SAS Strategy 2011. A possible ambiguity in dialectical process is explored as it relates to an organization?s ability to effectively influence the understanding and identity of its employees through discourse.
Framtidens begravningsplatser : en historisk tillbakablick, dagssituationen och visioner för framtidens gestaltningsuttryck
The purpose of this article is partly to find out how
the burial grounds are used today and the needs of its
visitors, but also to develop the character and
expression of future burial grounds. My suggestions
focus on burial grounds without religious attributes;
something that, according to the burial law
(Begravningslagen, 1990:1144), the manager of the
burial ground is ordered to obey. In my design I aim to
fulfill any requests regarding the place of burial that
have been raised during my study.
I have chosen the history of burial grounds as my
starting point and will subsequently discuss their
significance in today's society. I describe what
distinguishes the burial ground throughout history
from medieval times and onwards. Tradition and
religion are closely linked regarding burial rituals.
Stålfiberarmerad betong för platta på mark : -En kostnads- och sprickbreddsanalys
AbstractToday there is an opportunity to reinforce concrete with steel fiber reinforcement. In some cases, completely replace the conventional reinforcement. Replacing conventional mesh reinforcement with steel fiber reinforcement in slabs on ground has shown economic benefits, less crack width and less reinforcement amount.Today there are no Swedish standard for designing steel fiber reinforced concrete, what is there is different international recommendations.In this work, design methods for steel fiber concrete are used according to RILEM and Bekaer Swedish AB's software DRAPRO. For other design methods Eurokod 2 is followed.In this work, the design of slabs on ground that are not exposed by large tension strength been designed. Design of crack-reinforcement and restrictions of crack width have been conducted in three different slabs on ground.The calculations have been performed using only conventional reinforcement and only steel fiber reinforcement, and the results are then compared.The results of the theoretical analysis are summarized in tables that compare the amount of reinforcement, crack width and economic cost.This work showed that the slabs on the ground reinforced with steel fibers provide less crack width with a minor amount of reinforcement.
Räder och svensk doktrin samt reglemente för markoperationer?
NATO, USA, Storbritannien och Ryssland m.fl. använder sig av stridsuppgiften räd för markstridskrafter och erfarenheter från bl.a. Irakkriget 2003 visar att de kan få stor betydelse. Räder anses överensstämma med manöverteorin, men räder återfinns inte som stridsuppgift för svenska markstridskrafter.Denna uppsats analyserar stridsuppgiften räd för markstridskrafter, operationaliserar två indikatorer för räder och med hjälp av dessa undersöks hur räder är förenligt med FM nuvarande doktrin och Reglemente för Markoperationer (RMO).Undersökningen visar att räder inte är förenliga med nuvarande doktrin och RMO. Bl.a.
"Man får liksom inte bli slav under nationella prov" : en undersökning om lärares reflektioner kring de nationella proven i årskurs 3
Since the beginning of 1940 there have been externally developed tests in Sweden. Their appearances have changed over the years together with the cognitive approach. Nowadays, this kind of tests is going by the name of the national tests, which was introduced in the year of 1994. When the Swedish National Agency for Education received the assignment to develop new purposes and national tests to the third grade students, debate took a bounce. The matter was well discussed; national tests in third grade or not?The national tests thus far carried out four rounds in the third grade and the purpose of my study was to find out how teachers are reasoning about the tests.
Vakuumisolering ? Ekonomiskt försvarbart för småhus?
The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.
Tredimensionell fastighetsindelning : med fokus på tillbehörsproblem
Real estate is defined as ground, which is divided into property. Ground means every part of the surface, which is situated within the country. There is no legal definition of property to be found. Property is usually explained as every unit, which legally should be registered in the register of landed properties. To constitute a property the property must permanently be suited for its purpose.
Att få sätta spår : om medbestämmande och platstagande på gymnasieskolgården
Every place is a stage where people interact. The nature of the stage and its scenography to some extent shapes the interaction.
Considered as a place, the school ground gives rise to many varying expectations. Lower school pupils often have clear ideas of how they are expected to behave and how they are expected to use the place. But as the pupils age, the purpose of the school ground grows less obvious.
Kan Olikheter ena? En studie om sociala rörelsers potential att skapa dialog
In the process of globalization, identity has become one of the central factors.An understanding of the difference that makes up our society has made thequestion of weather is it possible to envision a society where difference is thecommon ground, one that has been up for contest. To answer this we need to seeif this kind of democracy is possible at all. For this I?m turning to the socialmovments who while they are working close to the reality also can give us somereal answers. Therefore I have looked at how social movements adress identity,difference and conflict and concluded that three things are crucial in organizing ongrounds of difference.
Ryskt luftmaktsanvändande i Georgien 2008 ? ett fall av Warden?
The Russian-Georgian war of 2008 drastically changed Europe´s and Sweden´s political climate.Russiashowed that it is capable of successfully completing complex campaigns including ground, naval and air assets. However, not much has been said about the theoretical framework and doctrine of the Russian military of today. Even less has been researched about Russian use of air power and applied air theory. Are air power assets still considered primarily as support of ground offensives or has the theoretical framework changed?John A.
Förbättring av U-värde i träkonstruktion för fönster med Aerogel
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
Den värdefulla insidan : en fallstudie av Swedbank Stadion
The purpose of this essay is to look at the Swedbank Stadion, which is a modern stadium in the south of Sweden. Swedbank Stadion is the home ground of Malmö FF, one of the largest football team in Sweden, and the goal is to create value for the team. The stadium owners have to get companies to hire premises inside of the stadium so they can pay for the home ground of Malmö FF. Therefore we have focused on the servicescape in the stadium and how it can create value for the companies that act on Swedbank Stadion on a daily basis.This study of the Swedbank Stadion is based on a qualitative approach. The qualitative approach is chosen because we wanted to establish deeper understanding for the case itself.
