Mjölkningsfrekvensens påverkan på mjölkproteinets sammansättning och kvalitet :

In modern dairy production the milking frequency is increased in some herds due to introducing of automatic milking systems or the farmers decision to milk high producing dairy cows more than two times a day. With more frequent milkings the milk yield increases while the content of fat and protein decreases. However, how the composition of protein is influenced is not fully evaluated. The purpose of this study was therefore to see if a higher milking frequency had any impact on the milk production and especially on the protein composition. This study was conducted as a half udder experiment.

Optimering av ett mellanspänningsnät : Optimization of a medium voltage electricity grid

EU vill genom att använda energin effektivare sänka sina energikostnader och minska sitt beroende av externa leverantörer av olja och gas vilket leder till att miljön skyddas. Av den anledningen krävs att energieffektiviteten ökas från produktion till den slutgiltiga konsumtionen inom EU. Jämtkraft är miljöcertifierat enligt ISO 14001 och arbetar därför årligen mot uppsatta miljömål. Detta examensarbete har studerat ett av dessa mål, möjligheten att minska överföringsförluster i ett av Jämtkrafts mellanspänningsnät. Området som examensarbetet baseras på är fördelningsstation Nälden FS23.

A cost benefit analysis of public procurement of pork meat : imported, Swedish or locally produced?

Public procurement stands for a substantial part of the total food consumption in Sweden. The majority of the procured food is today imported and according to market trends it?s intended to stay that way. Imported food is favoured for locally produced due to price pressure. Consequently domestic pork farmers have declined by 25 percent during the last twenty years.

Undersökning av exponeringsindex för bildplattesystem inför optimeringsarbete

The county hospital of Dalarna has for the last couple of years carried through a process of digitalization. The result is that within the county it exists image plate systems from two different manufacturers. In an attempt to create a tool for dose optimization and dose surveillance the county of Dalarna would like to investigate if the exposure index from Agfa and Fuji is suitable as a dose indicator. An investigation of the exposure index, S, from Fuji has already been done. This thesis has been continuing the investigation by evaluating the stability of the exposure index, lgM, from Agfa.

Om Gud vill får jag stanna ? en studie av hur nyanlända asylsökande upplever det mottagande de fått i Sverige.

The purpose of this essay has been to investigate how newly arrived asylum seekers experience their first month in Sweden. The focus has been on the introduction week that is given within the first month of their arrival, although the study aims to treat the reception that is given in general. This is important because the refugees are in a sensitive state, leaving their country for different reasons, and coming to a new place wich they know nothing or little about. The questions at issue has been the following; * What are the refugees´ views of the information and the treatment they´ve been given during their first month in Sweden? * Which are the possible reasons for the refugees experiencing the reception the way they do? The methods I´ve used have been observation studies during the introduction week, plus interviews with participants of this introduction.

Utredning av variablerna som påverkar storleken på brytspänningen i lindningskopplare

Brytspänningen är den spänning som uppkommer när överkopplingsmotståndet i lindningskopplaren lämnar sitt föregående läge vid omkoppling. Storleken på brytspänningen i lindningskopplaren beror på hur stor läckinduktansen är. Är den inte känd så kan brytspänningen istället beräknas med hjälp av FEM-programmet ACE (internt ABB-program) i samband med Mathcad. I ACE beräknas först reaktanserna i p.u-enheter mellan lindningarna och hur stora de är beror på lindningslayouten. Det är tidskrävande att använda ACE och Mathcad och uppgiften är att utreda de parametrar som påverkar storleken på brytspänningen samt att ta fram en förenklad beräkning av densamma.Genom simulering i ACE av en mängd olika lindningslayouter visar det sig snart att det är alltför många parametrar som påverkar reaktanserna.

Konstruktion av datainsamlingskort för mätsystemet COMET

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

Dokumentation av en experimentell biogasanläggning

This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed. For further notification, I am not   responsible for the programming of the devices in LabVIEW   which I have only used as a tool in my work. The plant   for production of biogas consists of four reactors   of which the third reactor (Lakbädden)   is connected to another reactor (UASB)   where they cooperate with each other.   The reactors are used for producing   biogas in the form of methane gas.The reactors I and II are   connected to, various electrical devices as, flow meters, temperature   sensors, frequency converter and   more.

Analys av mellanspänningsnätet i centrala delar av Västerås stad

The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

Annonseringsmediet Spotify - Nya möjligheter för mindre företag

The use of streaming media such as Spotify has increased rapidly in recent years. Although the consumption side of Spotify is well established with over 10 million users, the medium might provide new unexploited opportunities as an advertising channel. The purpose of this thesis is to increase knowledge about advertising through streaming media and in particular via Spotify. To contribute to such knowledge we have conducted a case study to investigate how Spotify can be used and serve as an advertising medium for a smaller firm, Hasseludden Yasuragi, so that it may reach its target group. To examine the medial effect, a quantitative as well as a qualitative study was carried out using the ARF Model as a basic framework.
