Alternativa skogsbruksmetoder i Norden : ett välbehövligt komplement?

Clearcutting systems have been the dominating silvicultural approach during the last decades in the Nordic countries. While economically rational, it is also leading to a trivialisation of the flora and fauna, and may result in negative reactions of people in urban settings. As a consequence of this, and a more diversified view on which goods and services forests should deliver, there is an increasing interest in broadening the range of silvicultural methods that are used. The term continuous cover forestry (CCF) represents a suite of methods that have gained increasing interest in the Nordic countries. In CCF a considerable amount of the trees are left after harvest to favour values that require a continuity of tree-covered areas. There are thus hopes that this method will meet the needs for maintaining biodiversity and satisfy social and cultural values.

Telemedicinska samarbeten : - Låt kunskapen flöda!

Inom hälso- och sjukvården spelar informationsteknologi en allt större roll för utvecklingen. Informationsteknologin har skapat nya förutsättningar där chansen till förbättrade vårdrutiner finns inom många områden genom att införa och utveckla användandet av telemedicin.Då vi tror att den telemedicinska potentialen kommer att användas i större utsträckning i framtiden känner vi att det finns ett intresse för en utredning av redan existerande samarbeten inom telemedicin. Vi skrev denna uppsats med syftet att undersöka, identifiera och analysera vad som krävs för att möjliggöra ett effektivt telemedicinskt partnerskap inom sjukvården för att förbättra patientens vård, behandling och ta tillvara på de arbetsprocesser som skapas i och med ett telemedicinskt samarbete. Vi har analyserat två olika typer av telemedicinska samarbeten. Vi har genom en kvalitativ undersökning, främst genom intervjuer, grundligt undersökt två av de bestående nätverken för att sedan analysera dessa med hjälp av den modell vi har sammanställt från de teorier om nätverk som vi utgått ifrån.Utifrån analysen om Konsensusnätverket är slutsatsen att samarbetet har lett till en förbättring av kvaliteten i behandlingarna.

Being the media : decentraliseringen av nyhetsproduktionen och dess effekter på tidningsjournalisters informationsbeteende

The Internet provides the common user with a variety of both traditional and non-traditional news sources, and a vast range of possibilities to contribute to the flow of information. By their participation in the production of information ordinary citizens can sometimes function as non-traditional news sources them selves and reach a potentially unlimited audience. The interactive nature of the Internet blurs the line between producers and consumers, and challenges traditional definitions of what counts as "news" as well as who qualifies as a "journalist". The main purpose of this thesis is to examine the potential consequences of this decentralization regarding the information behaviour of newspaper journalists and their perception of their professional role. The study consists of qualitative interviews with six journalists, employed by four of the leading Swedish newspapers, and a review of earlier research in the field.

Tacklingar, svett och rullskridskor - om den feministiska potentialen i sex kvinnors upplevelser av sitt utövande av roller derby

In this thesis the fullcontact sport roller derby is examined and it´s potential to work as a feminist strategy. Through interviews with six women who are active in the Gothenburgbased team Gothenburg Roller Derby the performative aspect of the sport is examined. Focus in the study is toinvestigate how, according to the informants, roller derby can challenge conventional norms about sex and gender. The result of the study shows how the informants through their participation in roller derby are able to perform a different type of femininity and in this process also are empowered as women. The study also shows how the women-only-aspect of the sport is of greatimportance in their experience of roller derby..

Viltanpassad röjning längs skogsbilvägar som en foderskapande åtgärd för älgen

The moose is a keystone species in the boreal forest ecosystem, but the dense Swedish population do cause some serious problems. From a forestry perspective, their browsing on young Scot pine (Pinus sylvestris) causes extensive losses of revenue. Adjusting the cleaning along roadsides of low trafficked forest roads can favour the production of plant species preferred by the moose. This is thought to redirect the moose´s browsing to the roadsides and thereby decrease the damages on commercial forest.The aim of this study has been to present a first evaluation of the vegetation in roadsides, one year after wildlife-adapted roadside clearing has been undertaken. In the wildlifeadapted clearing operation, the roadside was widened by removal of some trees in the forest edge whereupon a complementary clearing with a conventional chain flail was conducted.

Grön marknadsföring i detaljhandeln

The purpose with this research is to examine how the green marketing in retail trade can be developed in order to promote the eco-labeled products closer to the consumer.The method for the survey includes interviews with managers of a few retailers and their customers in the industrial sector. The purpose with the interviews was to produce the retailer and the customer?s perspective of products with eco-label on.The research is limited to the region of Västra Götaland.The results from this research indicate that there is a lack of communication between the retailer and the consumer. The consumers don?t think that the product is available.

Energivinst vid hybridisering av hydrauliskt system

Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.

När ska dieselelektrisk framdrift av fartyg väljas?

Diesel electric propulsion is in many ways a good alternative to conventional shaft propulsion, both economically and environmentally. There are also many other good side effects which need to be considered, i.e. better manoeuvrability, more efficient use of space and less noise on board. However, there are applications where diesel electric propulsion is not profitable. Large ocean going ships? profitability is much depending on fuel costs and the diesel electric alternative cannot compete on long journeys with large low speed engines.This thesis will treat the aspects of choosing between a diesel electric system and a classic mechanical propulsion system.

Sekundärnät för lågtempererad fjärrvärme

Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.

Betydelsen av information till patienten - om jodkontrastmedel påverkan i kroppen

Bakgrund: Kontrastmedel är ett flytande medel som injiceras i kroppen för att förstärka skillnader mellan kroppens olika vävnader. Jodkontrastmedel används varje dag i samband med vissa bestämda röntgenundersökningar. Effekten av kontrastmedel underlättar för att få en bra bilddiagnostik. Användning av kontrastmedel är inte riskfritt eftersom kontrastmedel kan orsaka negativa reaktioner som kan uppträda antingen som akuta eller sena, exempelvis hjärtstillestånd eller klåda. Syfte: Att belysa vikten av information till patienten om risker och biverkningar inför intravenös jodkontrastmedelsinjektion samt att belysa röntgensjuksköterskans roll och ansvar i samband med denna information.

Giraffens blodtrycksreglering

Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.

Fröodling av Raj- och rörsvingel i Sverige

Festulolium (Festulolium) and tall fescue (Festuca arundinacea) has not been grown inSweden over a longer period. So far there is no greater area cultivated, but the area isincreasing. Festulolium and tall fescue are expected to eventually replace meadowfescue in many leyseed mixtures to dairy cows in southern and central Sweden. Tallfescue has in recent years become popular again. Festulolium is a hybrid betweenryegrass and fescue.

Utveckling av dataanalysprogram för Opcon Powerbox

Opcon Powerbox is a product developed by Opcon together with the underlying company SRM (Svenska Rotor Maskiner) where surplus heat from the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower temperatures than the conventional Rankine process.In this master?s thesis a data analysis software for the Opcon Powerbox has been developed in which measurement data is retrieved and handled from the Opcon Powerbox.

Mekaniserad plantering med Eco-Planter i södra Sverige :

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Södra Skogsägarna and the aim of the work was to investigate the economical and biological output after mechanical planting with Eco-Planter compared with traditional manual planting. Eco-Planter is a tool for mechanized planting, fixed at the end of the boom on a conventional harvester. The study confirms that manual planting is less expensive under normal conditions. However, the differences between mechanized and manual planting are not that big and with technical development and/or increased labor costs together with an improved work organization the system with Eco-Planter could be competitive. The biological output, e.g. planting result and survival rate, seems to be quite good.
