Konsumenters synsätt på ekologiska livsmedel avseende frukt, grönsaker & rotfrukter : - En tvärsnittsundersökning ur ett konsumentperspektiv

Background: Pesticides in conventional food may be related to morbidity and mortality. Furthermore pesticides have a negative impact on the whole ecosystem. Organic food can presume better health as they contain less chemicals and toxins and contribute to sustainable development efforts.Objective: The aim was to examine what attitudes consumers have regarding to purchase organic fruit, vegetables and root vegetables.Methods: The association between consumers? views on conventional food and organic food was investigated using questionnaire given to a population sample of men and women aged by 23-65 (N=60) in grocery stores and in a fitness center. The study was based on a cross-sectional study in a municipality in central Sweden.Results: Consumers were interested to buy organic food.

En studie av metodbyte vid sintring av hårdmetaller till mikrovågsintring samt dess ekonomiska fördelar : Självständigt arbete i teknisk fysik med materialvetenskap & Självständigt arbete i kemiteknik

The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the manufacturing cost were made.The main difference between the two heating methods is that the conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.

Samarbete mellan lantbruksföretag : möjligheter och problem

Nowadays, cooperation is necessary and this study tries to illuminate the possibilities and problems about cooperation in fiction between 7 small/midsize farms in Skåne. Conventional Farming is done with grain and sugarbeets as specialization. Calculation of machine costs have been done and compared in the study, both for the farms in thorough and the fictitious operation companies. Business ratios as depreciation/ha, interest/ha and maintenance/ha have been calculated. In this essay we present a proposal about how a practical implementation can be done. In the proposal there is an example how the distribution of work can be done.

Informations- och kunskapsflöde i byggbranschen : En studie av informations- och kunskapsflöde till och från produktionsledare

This report that is written in cooperation with Peab Sverige AB, studies the information and knowledge management from the production support to the production management. The conclusion of this report is that to have a good and functional information and knowledge management it is necessary that the company has a good way of regain and handling experiences from its projects. The way to do this is to develop the managing system on the production management?s terms. It is also critical to find an easy way for the production management to use the system..

Miljöbilar - ett steg närmare en bättre miljö

This report concentrates on why more people do not choose an environmentally friendly car instead of a conventional car. To find this answer we have used theories that include decision - behavior and environment - philosophy. We have also made four surveys, which includes several interviews. The results of these interviews, together with the secondary data we have found, have been analyzed against the theories made by our choice. We have found that the stimulus that we have today isn?t enough to make more people choose an environmentally friendly car instead of a conventional car.

Produktionsavbrott - förekommer det effekter att lära av?

A large part of the time losses in production in modern manufacturing industry are a cause of unplanned interruptions in production. In this essay we have studied the effects of an unplanned interruption in production. The study was performed during one month on a press production line at Volvo Cars Body Components (VCBC) in Olofström. The effects of the interruptions have been studied on the basis of two perspectives of the environment of the production. The study started at the level of automation and was mainly done as a survey of the unplanned interruptions in production.

ABB Capacitors is looking to introduce LEAN within their organization. The purpose of this research is to suggest ways to improve the production planning in order to facilitate the company?s production processes. This should be done in accordance with the LEAN concept.Today, ABB will produce two of the customers? orders at the same time.

Håller vindkraften vad den lovar?

The purpose of this study is to investigate how much of the estimated annual electric energy production from Swedish wind power that actually was produced, as well as the history of this agreement over time. The aim is to also examine if there are properties that have caused some group of wind power plants to produce more or less, compared to their estimated production. Operational data on wind turbines collected by the Swedish Energy Agency was analyzed. A survey was made among owners of wind power plants with a nominal power of at least 2 MW. Two different methods for normal year correction of production data were used and compared.

Effektivisering av produktionsgrupp : Improving the efficiency of a production group

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

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.

Barriers to convert to organic farming and the role of risk : an empirical application on Swedish data

To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.

Utvärdering av svensk vindkraft : Skillnaden mellan skogs- och traditionella placeringar

During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good..

Textilhantverkets betydelse i Uppåkra - en studie av Uppåkra och närliggande agrarboplatser

This survey deals with textile production and how it was carried out during the late Iron Age,with main focus on a central place, Uppåkra. A comparison has been carried out betweenUppåkra and two agrarian settlements, Fosie and V. Karaby, from the nearby landscape toinvestigate whether any variation in production can be detected. The value of textiles has alsobeen investigated to determine whether a potential specialization in production may have ledto a surplus.An analytical and comparative method has been used with focus on the context of thematerial.The results show that the textile production vary at the different sites, and that a need fordifferent types of textiles has existed. At Uppåkra, the possibility to produce fine threads andtextiles existed as demonstated by the findings of small and lightweighted spindle whorls.This suggests that the production may have included both fine and coarse textiles.

Bacterial contamination of eggshells in conventional cages and litter floor systems for laying hens in Jordan

In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.
