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.

Modellering, identifikation och reglering av en quadcopter

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

The Instant Generation : - hur ser ungdomars attityder till fildelning ut?

Abstract:Title: Engelska (Svenska)Number of pages: 40 (47 including appendix)Author: Carl StrandTutor: Göran SvenssonCourse: Media and Communication Studies CPeriod: Fall 2005University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The purpose of this essay is to analyze how young people, in the ages 18 to 25, relate to the subject of file sharing, and what their attitudes to this phenomenon are. I aim to describe how they use file sharing, their knowledge about it, how their usage have changed due to the new copyright law, what their stands are on the question of resource control and management on the Internet, and what they think of the future of file sharing.Material/Method: The method being used is a qualitative focus group interview model, used to investigate how young people look at the subject of file sharing. The results of the interviews is then applied to a theoretical framework based on thoughts of Denis McQuail, Lawrence Lessig concerning creativity, copyright, resource management and file sharing on the InternetMain Results: My conclusion is that the widespread file sharing habits of young people is not only caused by the temptation of getting free stuff, but of the lack of commercial and legal alternatives. Youths are willing to pay for media if the distribution is superior to the illegal file sharing alternative. They are a generation of young people that has grown up in a society where the tendency in many fields has been to make everything faster and more effective.

Projektering av fårstall :

The purpose of this work was to see if it was possible to rebuild an old dairy house into a house fore sheep production. The goals fore the work was to see witch kind of production model was suitable, how the actual drawing would look like and witch kind of interior was needed. The building was built in the beginning of 1900. It is located on the mountain Kinnekulle in Sweden. It was a big production fore its time and hade about 60 dairy cows. It was a lot of hard work because the floor was built by big stone blocks and it was very hard to rebuild when some more automatic solutions came fore handling all the manure. The idea of remaking the building came when we rebuilt the roof fore 5 years ago.

Analys av turbulensmodeller för CFD

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

Sociala medier och turism : Logga in! Hela värden får veta vad jag tycker, men vad tycker turistaktörerna?

The purpose with this study is to enlighten and discuss the information and communication which is spreading through social media, about the tourist operators and also to examine the operators view on social media. Social media can be described as a tool to use word of mouth on the Internet. To make this possible, five actors involved in tourism were picked on Gotland and interviewed for a content analysis. The results showed that the use of social media as an information channel before the consumer buys a trip, has increased. The study also shows that the selected actors have a lot of work to do, before they understand how to use the social media in their best interest for further developing their companies.

Förrotation till omrörare

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

Lévinas och den andre. Nycklar till en gångbar etik i det postmoderna samhället

Emmanuel Lévinas is one of the great ethics in the 20th century. His contribution to the philosophical discourse defies our thinking and behavior in a revolutionary way. He dismisses every categorization, every tematization, every moral based on an analytical reflection and compels us with an ethics that demands us not only to think, but to act and be responsible. The 21st century?s emphasis of the individual, globalization, plurality and the questioning of authorities has created new challenges for the individual who sees herself as the nave of morality.

Habitat use and ranging behaviour of GPS tracked juvenile golden eagles (Aquila chrysaetos)

Throughout its wide distribution in the northern hemisphere, the golden eagle occurs in a diverse range of environments, e.g., mountainous, forest and open areas. The literature on juvenile golden eagles is limited, and this study provides further knowledge on habitat use and ranging behaviour during the post-fledging period in boreal Sweden. A total of 14 golden eagle juveniles were tagged with GPS transmitters during 2010 and 2011, and nine could be followed during the entire post-fledging period from fledging until migration. The juveniles fledged at the end of July and beginning of August and initiated migration during October and beginning of November. The length of the post-fledging period, until migration started, ranged from 49 to 97 days. During this period, the juveniles? distance from their natal nest and their GPS height increased with time as their flying abilities developed.

Abstract This qualitative interview study focuses on job coaching by examining what thoughts, views and opinions the involved parties, such as job applicants and job coaches, have of the contribution. The aim is to highlight the obstacles and opportunities by examining the expectations that exist from both parties as well as how to look at job coaching and its different areas. In this context, examine the similarities and differences between the two parties approach to the contribution. This is made possible through four interviews with job applicants as well as four interviews with job coaches. A grounded theory inspired approach was used to obtain the results of the study.

Näringsämnesretention i fyra nyanlagda våtmarker i Falkenbergs Kommun

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

Tvådimensionella rum

We are always surrounded by space, not just only in a room with four walls, but also when we are outdoors.Constantly we move in a flow of space that changes whenever we move. Unaware we are affectedby this threedimensional surrounding of ours, and it reacts with our perception. Many times, we chooseto translate it into something two-dimensional, for example when we take a photo, recording a movie orframing a view with a window. It helps us to catch a moment, a piece of reality and restore it in our ownway. In this project I?ve chosen to explore this process, to interpret and create my own theories about thistranslation from space to a two-dimensional surface.
