Flodpärlmusslans status i Laxtjärnbäcken : Effekter på flodpärlmusslan av sedimentbelastning och förekomst av bäckröding

The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.

Byggnadsarbetarens syn på att bli involverad i projekteringen : En intervjustudie i byggprojekt

Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews.          The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.

Konstruktion av efterbehandlare

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

Malmö stadsbiblioteks nya informationsdiskar : Planering, utformning, höjd och placering

This Masters thesis in Library and Information Science has the title The New Information Desks at Malmö Public Library . During the rebuilding of the library in Malmö a new information desk was developed. This desk differs to a great extent from conventional information desks used in libraries. The information desk is triangular with rounded edges which allows the librarian and the user of the library to work side by side without any physical barriers. The aim of this thesis is to explore the requirements for the information desks formulated by the library and how they are perceived by the librarians and the users of the library.

En jämförelse avseende beståndsgående-och stickvägsgående gallringsmaskiner

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

Regeringens transportinfrastruktursatsningar : En studie av tågtrafikens utrymme i regeringsanslagen för transportsektorn

In the government's bill on infrastructure for 2010-2021, the government presents that road investments should be prioritized before investments in the railway. The grants for operation and maintenance of the railways are much higher then in the last government's bill. Furthermore the current founding of investment in railways is higher then for road investment which is in opposite of the bill on infrastructure's directives. Therefore the purpose with my thesis is to find which factors that can explain how come the government has chosen to take these actions. As a model to help me achieve my purpose I have been using a modified version of the DBO-theory, where the basic factors to explain an action is Desire, Belief and Opportunities.

Förstudier av kommersiella fastigheter : En analys av arbetssätt ur ett projektledarperspektiv

This thesis is written at WSP management and investigates the practice of pre-project planning and feasibility studies at Swedish construction companies, through the study of the ongoing feasibility study of the mall Sturegallerian in Stockholm, and through interviews with experienced project managers in the construction industry. There is currently a big span in the way Swedish construction companies plan the pre-project phase and the aim of this thesis is to present a more generic and standardized way that helps minimize project risks and maximize efficiency and profit. The result is a generic model which can be used in pre-project planning. The model describes the phases in the preproject planning process and the activities that span these phases. Is also describes the categories of professions that need to participate in the preproject planning group and which activities that each profession executes. The other result is a list of factors that need to be considered for a well performed pre-project phase, as found during the interviews. Among others the thesis stresses the importance of involving the client as a key participant in the process.

En studie av slaget vid Verdun och de taktiska grundprinciperna : Är Doktrin för markoperationer applicerbar på utnötningskrig?

This essay is about the tactical basic principles as they are mentioned in the Swedish Doctrine for land based operations (2005) and the German side during the battle of Verdun 1916. The purpose of this essay is to clarify whether the used doctrine is appropriate to use on future attrition battles.        This is done by a case study of the German side during the battle ofVerdun.

Finally the tactical basic principles are analysed and discussed based on the questions that the essay is based on.In the analysis and the discussion the conclusion is drawn that the tactical basic principles were present on the German side during the battle of Verdun and that they are of a general character and may be applied on both attrition warfare of 1916 and modern battles of attrition..

Förutsättningar och hinder för att använda offentlig upphandling som styrmedel för en hållbar hantering av entreprenadberg

Large volumes of excavated soil and rock are generated in building- and construction projects. These materials need to be transported longer and longer distances due to the densifications of cities. The transportation affects the environment in terms of noise and emissions, but also makes high demands on road infrastructure. To reduce the transport distances an increased responsibility for the excavated rock generated needs to be taken. Responsibility can be increased through an introduction of means of control.

A tricycle construction was chosen because it?s the simplest. Communication between the robot and the computer also kept as simple as possible..

Det kanske är lite meningen att man ska vidga sina vyer. En undersökning om yrkesförares inställning till läsning och användning av vägkrogsbibliotek.

This Masters thesis is a study of the truck-driver profession and their use of libraries located in gas-stations and restaurants along the highways in Sweden. The reason for this interest is the positive trend that has occurred concerning men without any university education and their reading-habits, that is due to their increased interest in listening to audio books. This challenges the general opinion that this group is not particularly interested in reading literature. Questions posed in this study are: How do the truck-drivers relate to the activity of reading literature, what part does the road-libraries play, and how can the services that the road-libraries offer be improved according to the truck-drivers. The method used in the study is interviews made by telephone.

Utvärdering av BeWi Byggsystem

The construction industries are relatively conservative type of business that takes a longtime to adjust for new methods and embrace new ideas. It dose not matter if the newmethod seems to be an improved method as long as it is new and untried. Constructioncompanies are reluctant to change form a longtime working method to a relativelyunknown method.The purpose with our report is to perform an evaluation of BeWi construction method.Our goal are to present the generally opinion about BeWi from the contractors that hasbeen in contact/worked with the method. We also want to know from the contractor?spoint of view if BeWi and the method measure up to the standards that are presented byBeWi and if they believe that improvements need to be done.Our progress up to the final report has consisted of three parts[1]Field studies[2]Interviews[3]Literary studiesWe started out with field studies where we took notes and observed all the includedworking phases on the construction site when using the BeWi method.

Personsäkerhet vid väderskyddsbyggande : En kartläggning över dagsläget och problematiken med frånvaron av föreskrifter i branschen

This paper, Personal safety when working with weather encapsulation constructions, is focused on weather encapsulation constructions and how the absence of Swedish standards and regulations is affecting the safety for the workers. The usage of weather encapsulation construction is increasing in Sweden therefore the needs for standards and regulations are becoming more and more urgent. The risks involving the rising and the demolition of the weather encapsulation construction and when the construction is transported along its rails are treated in the paper. Since there are no regulations companies have had to solve the safety issues without instructions, the paper regards how the companies have solved this problem without the support of formal institutions..
