PLM-SYSTEM FÖR TILLVERKANDE MINDRE FÖRETAG : EN STUDIE OM LÄMPLIGHETEN AV PLM-SYSTEM OCH FÖRANKRING GENOM CHANGE MANAGEMENT

This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.

Broiler production in Zambia - management, growth, diseases and welfare

Successful broiler production in hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare. The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.

Fordonsgas eller el-produktion vid Centrala Reningsverket Kristianstad? : skall producerad biogas vid centrala reningsverket nyttjas som fordonsgas eller användas till el-produktion?

Varje månad produceras 100 000Nm3 (normalkubikmeter) biogas vid centrala reningsverket i Kristianstad. Denna gas används primärt som uppvärmning till lokaler på området genom tre gaspannor lokaliserade i källaren under huvudbyggnaden. På gasnätet finns även en uppgraderingsanläggning inkopplad som kan ta ut gas som sedan uppgraderas till fordonsgas. Gasen som går till uppgraderingsanläggningen generar en årlig intäkt på cirka 700 000:-. Överbliven gas lagras i en gasklocka och när denna är full facklas överskottet av gas upp.

Att skapa nya rum : Roomservice - en annan form av marknadsföring

Due to the technical development the enterprises of today are forced to creative thinking when it comes to marketing of their products. An example of one of these new methods are the development of product placement which has come to an interesting turn namely advertiser funded programming (AFP). Instead of the product just being a small part of the storyline it has become the story itself. The purpose of this study is to analyse how the advertiser funded tv-production Roomservice, a Swedish home styling program, communicates with it?s viewers as well as how they perceive the message.

Biogas, en lönsam investering för framtiden

Den globala uppvärmningen är ett faktum och behovet av ett hållbart energianvändande av en förnyelsebar resurs är större än någonsin. Regeringens vision är idag (år, månad) att Sverige ska få en fossilfri fordonsflotta och en hållbar resurseffektiv energiförsörjning utan nettoutsläpp av växthusgaser innan 2030. Biogas är ett förnyelsebart bränsle som inte bidrar till nettoutsläpp av växthusgaser och är således ett fullgott substitut till fossila bränslen. Biogasmarknaden är idag osäker, detta beror på att det finns ett intresse hos fordonsaktörer för biogas men ännu inte viljan att ställa om på grund av den begränsade tillgången av biogas. Samtidigt anser potentiella biogasproducenter att efterfrågan på biogas är för låg från fordonsaktörernas sida för att de ska investera i en biogasanläggning.

Från alger till biodiesel - Den italienska drömmen?

This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.

Effects of biogas residues on respiration and denitrification in arable soil : evaluation of methods, microbial activity and agronomic implications

Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.

Marknadsföring av lokal mat : en fallstudie av tre livsmedelsproducenter

The process of food production has changed dramatically over the past one hundred years. Industrialization has led to large units of production, manufacturing, distribution, marketing and retail business. The final food product, in this system, is quite often fairly anonymous and the consumer will most likely know very little concerning the origin of the product. In recent years, the market for locally produced food has grown. There is an increasing interest in and demand for locally produced food items.

Lantbrukaren som energiproducent : en fallstudie i energisatsningar inom lantbruket

The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production. Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy. The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.

Svenska hushålls vedarbete : en fallstudie i Umeåregionen

In Sweden there are 354 000 private individuals owning forest. Of these forest owners there are at least two thirds that are self-employed, which means that about 215 000 forest owners conduct some kind of work in their own forest. Those numbers do not refer to firewood production, but every year 7.3 million piled cubic meters of firewood are used for heating Swedish households. This implies that many households are also producing firewood. The objective of this study was to assess and analyse the small-scale firewood production in the Umeå-region in terms of persons engaged in the work, equipment used, produced volumes and share of forest-owning households involved in these activities. According to results from a questionnaire, the average firewood producing person is a man between 40-60 years old.

Mikroalgbaserad biogas - ett raffinerat bidrag till en hållbar stadsutveckling

I detta arbete undersöks möjligheterna att använda mikroalger som råvara för produktion av biogas, både genom en litteraturstudie och genom en förstudie för hur en pilotanläggning för hållbar odling av mikroalger för biogasproduktion skulle kunna initieras. Utgångspunkten är hållbarhet, vilket innebär att odlingen av mikroalgerna baseras på befintliga, outnyttjade samhällsflöden. Avloppsvatten och koldioxidutsläpp är exempel på flöden som kan orsaka negativ miljöpåverkan i form av klimatförändringar, övergödning och försurning. Om dessa resurser istället får utgöra närings- och kolkällor vid odling av mikroalger för produktion av biogas utnyttjas dessa resurser istället till att generera hållbart producerad energi. När biogasen ersätter fossila bränslen ökar miljövinsten ytterligare.

OTEC-Ett energialternativ för enhållbar ö

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

Normering av Rösthandikappindex och Halsskalan för personer över 65 år i Sverige.

The population over 65 years of age is increasing and health in elderly has been a subject of research for decades but voice function and vocal health has not been prioritized. The purpose of this study is to obtain reference value for the Swedish version of Voice Handicap Index (RHI) and the Throat Scale among people over 65 years of age and assess voice function and vocal health for this age group. The questions were as followed:1) What is the reference value of RHI for people over 65 years of age? 2) What is the reference value of the Throat Scale for people over 65 years of age? 3) Is there a correlation between a self-rated VA-scale on the perceived degree of voice problems, and the self-rated RHI-/Throat Scale result? 4) Does age, gender or previous profession matter for the self-perceived voice?In total 100 individuals participated in the study, 50 women and 50 men, between 65 and 92 years old. The reference value of RHI for people over 65 years of age was 13,4 points and the reference value for the Throat Scale was 7,7 points.

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.
