Implementering av statistisk processtyrning på en serviceavdelning.

På senare tid har företag i allt större utsträckning börjat mäta processprestationer istället för att enbart styras efter ekonomiska termer. Att lägga resurser på ständiga förbättringar istället för ?brandsläckning? har samtidigt blivit mer vanligt. Siemens Industrial Turbomachinery AB (SIT AB) i Finspång har arbetat med förbättrings¬konceptet Sex Sigma en längre tid och har som ett led i detta kommit långt i arbetet med processorientering. På serviceavdelningen har man börjat intressera sig för statistisk processtyrning (SPS) som ett sätt att koppla ihop processernas prestation med förbättringsarbetet.

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.

Teknikimplementering vid muddringsprojekt : Viktiga faktorer vid teknikval samt olika aktörers betydelse i processen

There are today large amounts of contaminated sediments in the Baltic Sea. These contaminants are the result of many years industrial activity where the contaminants have not been taken care of and just released out in the water. When ports want to dredge in their fairways and harbor areas the contaminated sediments need to be considered since they are a environmental risk. The development in this area has been slow and new techniques have just recently made its way into dredging operations in the Baltic Sea region. As a result of this there are no clear methods for implementing new techniques today.

Poultry producers? perceptions of changing market conditions : a field study of the poultry production in Khartoum state of Sudan

Sudan has always showed great potential in the poultry industry, but it has not been until now that this potential has blossomed and is growing quickly. As large agribusinesses1are taking over the market shares within the urban areas, smallholders2 have been put out of business. They are not able to compete with mass production and lack financial assets to improve their production techniques. Contract farming is defined as initiatives from agro industrial companies to secure access to smallholder produce and has in developing countries become a way of allowing the poor to participate in a larger market (Farrington, 1999). The aim with this study was to investigate the suitability of implementing the contract farming concept within the poultry industry in Sudan today. The study is a qualitative field study and the authors have conducted qualitative interviews with respondents involved in the poultry industry in Sudan.

"Sharing is caring" : Om Piratbyrån och kognitiv praxis i en ny social rörelse

Words like pirates and anti-pirates are becoming common features in the cultural political debate of today, and the file-sharing phenomenon has become a more and more delicate and disputed subject. The fact that people are organizing in networks to swap computerfiles with each other has, among other things, led film and music companies from all over the world to initiate a number of anti-piracy organizations, assigned to protect the right to culture and information. The industrial organization Antipiratbyrån (the Anti-pirate Bureau) and the network Piratbyrån (the Pirate Bureau) have on several occasions been used to represent the prevailing conflict in Sweden. The purpose of this study is to apply a sociological perspective to the collective act of file sharing. Additionally, the purpose is to argue that the activity can be understood as a social movement, although it is rarely referred to as such.

Urskogen med de stämpelbleckade gammeltallarna : en skogshistorisk tolkning av Brännlidens naturreservat

People have used forest resources in northern Sweden for different purposes. Before the 20th century the forest was used for many different reasons, but during the past 200 years it has become an industrial raw material. The presence of people in the forest has left different kinds of traces in the forests. One example is culturally modified trees (CMT´s). The aim of this study was to study and document how people have used the forest resources during the last centuries in Brännlidens nature reserve, and what kind of traces this land use has left.

Distansledarskapets spelregler - en fallstudie av utlokaliserade journalisters upplevelser av distansledarskap och arbetsmotivation

What is e-leadership and how can it be framed in a distance context? How can work motivation be understood as a correlated theme? In prior leadership research and theory it has been taken for granted that leadership occurs in a face-to-face environment, so how to study leadership in a remote context? According to recent research, e-leadership defines this leader-member relation in this new arena, and a central focus of this research has been on communication. Communication is a central theme in the remote setting because it is the only interaction arena which allows leadership to be seen and understood. By conducting a case study in a multi media organization with distance working journalists as focus group this essay aims to bring a deeper understanding of how e-leadership works and how it effects work motivation. The field of media organizations is interesting to study as distance work is not an unusual working environment for journalists, and research has indicated that work motivation needs for these highly specified creative workers are somewhat differentiated from other, for example industrial workers, which implies that motivation theories urges an update.

Rening av metallhaltigt avloppsvatten : En teknisk/ekonomisk utvärdering av reningsmetoder för metallhaltigt avloppsvatten

This Master?s Thesis aims to investigate and assess the methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna.Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste water.Assa has four plating lines: the Trumline, the big Zinkline, the new Zinkline and the Decorativeline. The new Zinkline is the most modern of the four lines and purification is done byrecirculation over an ion exchange unit. The demand for fresh water is thereby heavily reduced.The Trumline, the big Zinkline and the Decorative line all use older techniques.
